Discuss Two or More Psychological Explanations

Discuss two or more psychological explanations for institutional aggression. The importation model is a dispositional theory which states that an individual would bring in – import – characteristics from outside of prison which lead them to be aggressive in daily life. This then leads to aggression while incarcerated. Cheeseman said that men have a certain way of behaving, probably why they ended up in prison to begin with, which they then apply to their new setting. Irwin and Cressey found 3 subcultures within prisons, the criminal, the convict and the straight/conventional.They found that the convict subculture were most likely to be aggressive as they are influenced by deprivation, and bring values of this into the prison setting. Also, certain factors such as age, sex and race can affect the level of aggression you exhibit in prisons, as found by Janus. Support comes from DeLisi who examined prison records of 831 prison inmates from South West USA. They made note of prisoners who had been involved in street and prison gangs. They found a small but significant relationship between gang membership and prison aggression.This implies that they imported subculture values of being in a gang with them into prisons. Further support comes from Poole and Regoli who looked at juvenile correction facilities and found that inmates who were violent outside of prison where more likely to be violent inside of prison. This shows that they may have imported aggressive characteristics into the prison setting with them. However, in a real life setting this theory isn’t particularly useful, as it does not give any suggestions as to how aggression can be reduced within prisons.Also it is deterministic to say that people of a certain race, age and education level will be aggressive within prison as it ignores the fact that humans have free will and also would lead to stereotyping within prison. This theory can be considered socially sensitive as people will b e stereotyped and treatment towards them by others could change. This would in turn lead to scapegoating and possibly have a negative impact on the persons self esteem. The deprivation model is a situational model.Situational models say that it is the environment which causes aggression, not the individuals. This model suggests that aggressive behaviour within prisons is due to a prisoner being deprived of 5 fundamental rights that they would have outside of the prison setting. These include liberty –prisoners aren’t trusted to live in the free world, autonomy – prisoners have a lack of power – and security. When these are removed, it can lead to prisoners becoming stressed, anxious and often they act aggressively towards others to release this.Prison settings can also lead to deindividuation, as prisoners are represented by numbers and wear the same uniform as everyone else, causing them to lose their own identity. This can lead to aggression as individu als do not feel accountable for their actions. Also, the dysfunctional power systems model, outlined by Zimbardo, says that when people are given power without direction It can lead to aggressive behaviour. This is known as the Lucifer Effect, which was Zimbardo’s assertion that situations turn good people evil.An example that supports this is the treatment of Iraqi prisoners of war in Abu Ghraib. American military police tortured and abused Iraqi detainees after being given power to make sure they were ready for interrogation. This gave them the power to treat prisoners how they wished, without any restrictions on what is acceptable to do to them. This also supports the theory of deindividuation, as the soldiers were anonymous, and dehumanized the prisoners to make what they were doing appear justified.The deprivation model is culturally bias to a westernized culture, as in some cases where deprivation is common throughout life, prison may actually be a better environment fo r prisoners than their usual living environment, which would not explain any aggressive behaviour they may have. Also, in terms of applications to the real world, this model is quite effective, as if these deprivations were somehow prevented, it may improve aggression in prisons.

Geographical Information Systems (Gis)

1. Spatial data are what drive a GIS. Spatial features or entities and their attributes are stored in computers using a number of spatial data models. It is vital to understand the characteristics of them since the data model employed has considerable influence on the functionality of the GIS. Spatial data can represent real world features with discrete boundaries (such as roads, buildings, lakes, rivers, administrative boundaries) as well as real world phenomena with non-discrete boundaries (such as precipitation and nutrient levels, terrain).The basic approaches are: raster data model and vector data model. Depending on the type of problem that needs to be solved, the type of maps that need to be made, and the data source, either raster or vector, or a combination of the two can be used. Each data model has strengths and weaknesses in terms of functionality and representation. | Raster Data Model| Vector Data Model| Descriptions| The raster data model is the simpler model and is ba sed on the division of reality into a regular grid of identically shaped cells.Raster data represent the landscape as a rectangular matrix of square cells. In raster data model, attributes are limited to the numeric values of the cells themselves, and while it is possible to link additional attributes to the groups of cells having same values, which is rarely done in practice because of the low utilizing value and cumbersome data management. | In vector data model, an object’s shape is represented by dots which are located where the shape of the object changes.The dots which are known as vertices are joined by straight lines. Vector data represent features as discrete points, lines, and polygons. In vector model, as a point of difference, vector objects are additionally described by one or more characteristics, in GIS called attributes. Vector files attributes are stored in tables which consists of records (rows) representing individual features, fields (columns) representing a particular theme describing the feature, and attributes that refers to an intersection between a record and a field. Advantages| * The geographical location of each cell is implied by its position in the cell matrix. Accordingly, no geographical coordinates are stored other than an origin point. * Due to the nature of the data storage technique data analysis is usually easy to program and quick to perform. * The inherent nature of raster maps that is one attribute maps, is ideally suited for mathematical modeling and quantitative analysis. * Grid-cell systems are very compatible with raster-based output devices. As reconnaissance satellites and aerial surveys use raster-based scanners, the information can be directly incorporated into GIS. | * Data can be represented at its original resolution and form without generalization. * Graphic output is usually more aesthetically pleasing (traditional cartographic representation). * Allows precise representation of points, boundaries, an d linear features. * Accurate geographical location of data is maintained. * Since most data, e. g. hard copy maps, is in vector form no data conversion is required. Allows for efficient encoding of topology and operations that require topological information. | Disadvantages| * The cell size determines the resolution at which the data is represented. * It is especially difficult to adequately represent linear features depending on the cell resolution. Accordingly, network linkages are difficult to establish. * Processing of associated attribute data may be cumbersome if large amounts of data exist. Raster maps inherently reflect only one attribute or characteristic for an area. Since most input data is in vector form, data must undergo vector-to-raster conversion. Besides increased processing requirements this may introduce data integrity concerns due to generalization and choice of inappropriate cell size. * Most output maps from grid-cell systems do not conform to high-quality ca rtographic needs. | * The boundaries of the resulting map polygons are discrete whereas in reality the map polygons may represent continuous gradation or gradual change, as in soil maps. * The location of each vertex needs to be stored explicitly. Vector data must be converted into a topological structure to achieve effective analysis, which is often processing intensive and requires extensive data cleaning. * Continuous data is not effectively represented in vector form that usually requires substantial data generalization or interpolation for these data layers. * Spatial analysis and filtering within polygons is impossible. | References Heywood, I.

Basic concept of GIS As the name implies, geographic information systems (GIS) are systems designed to be input, store, edit, retrieve, analyze, and output geographic data and information.It is composed of an orchestrated set of parts, which includes computer hardware and software, space and organizations within which these reside, personnel who use the system in numerous levels and capacities, data and information upon which the system operates, clients who obtain and use the products, vendors who supply the hardware and software, and other systems within which the GIS functions. These parts allow it to perform its many interrelated tasks well. The main task of a GIS is to analyze spatially referenced data and in formation.There are various ways of classifying the analytical and modeling capabilities of GIS as many of these capabilities interact. Ultimately, the software most certainly contains algorithms and computer code specifically designed to: (i) Organize geographic data within appropriate referencing systems, (ii) Selectively query those data and aggregate them for easy understanding, (iii) Count and measure both individual objects and collections of objects, (iv) Classify and reclassify objects based on user specified properties, (v) Overlay related thematic map data, vi) And be able to combine these individual techniques into ordered sequences of operations designed to simulate some natural or anthropogenic activities for decision making. One of the purposes of using GIS is to take observations of the real world and simplify and scale the data into graphical elements to which are related descriptive features termed attributes. Database management system (DBMS) is used to maintain th e attributes while the graphical elements are described in any one of two general types of spatial structure which are vector and tessellation.Vector structures which refer to discrete elements, points, lines, and polygons, are represented digitally by a series of 2-D coordinates (x and y) that imply magnitude and direction. Whereas tessellation refers to representation of spatial data with a network of elements such as rectangles, squares, hexagons, equilateral triangles, and irregular rectangles. In general, vector methods are more suitable for mapping and performing spatial queries, while tessellation is more suitable to represent continuous surfaces such as topography.The history of development of GIS parallels the history of developments in digital computers and database management systems as wells as those in cartography and automation of map production. The development of GIS has also relied upon innovations made in other sectors including geography, photogrammetry, remote se nsing, civil engineering, and statistics. Generally, GIS can be very beneficial in various fields that some organizations are utilizing it, such as retail, utilities, environment, local government, health care, transportation and financial services.However, it could go wrong if the organization was not really sure how it could use it. It should be determined that how an organization uses spatial data and whether the current practices can be automated, and also identify any new processes which would be useful to help decision making. Some people believe that there is no difference between computer-assisted cartography (CAC), computer aided drafting (CAD), and GIS. Because the graphic display from these three systems can look identical to both casual and trained observers.Nonetheless, CAC computer systems that designed to create maps from geographical objects combined with descriptive attributes are excellent for display but lack of the analytical capabilities of a GIS. Also, for pure mapping purposes, CAC is highly desirable for the input, design, and output of mappable data rather than working through the myriad analytics of GIS to produce a simple map. Whereas CAD is developed to produce graphic images that is excellent for architects, but it is not capable of analyzing maps that it is the primary task assigned to the GIS.A successful GIS may not be an off-the-shelf solution to your problems, while it will require considerable thought for a successful implementation. Applications Nowadays, GIS technologies have been applied to diverse sectors to assist experts and professionals in analyzing various types of geospatial data and dealing with complex situations. GIS plays a vital role to help people collect and analyze related spatial data as well as to display data in different formats in business, education, transportation, public safety, natural resources, mapping and charting, geospatial intelligence, government, tourism, and health service.In agriculture, G IS can be very beneficial too as the ability of GIS to analyze and visualize agricultural environments and workflows has contributed much in the farming industry. Balancing the inputs and outputs on a farm as a fundamental to agriculture success and profitability can be determined easily through GIS. Pest/ disease tracking, farm management, crop monitoring, yield prediction and soil analysis can easily be done through GIS.From mobile GIS in the field to the scientific analysis of production data at the farm manager’s office, GIS is playing an increasing role in agriculture production by helping farmers increase production, reduce costs, and manage their land more effectively. In natural resource management, GIS has also played important role in various applications. For example, groundwater recharge potential evaluation platform, soil database query system, biodiversity geographic information system, climate rainfall map system, private forest land management system, water bo dy quality and pollutant management system, as well as rainfall analysis system.In planning and economic development, GIS helps economic developers in effective decision-making that it conducts analysis, displays and disseminates results and makes informed decisions about where to locate new businesses or grow existing ones. GIS technology is really powerful and efficient in helping economic developers sustain economic recovery and growth. The necessary platform for visualization, modeling, analysis, and collaboration can be provided by GIS tools and help the economic developers to achieve their goals.Next, for public safety, GIS contributes a lot especially in disaster management. There are some systems introduced to detect and prevent disasters such as GIS-based campus emergency system, disaster prevention area planning, urban disaster prevention spatial system, and emergency response digital map platform. However, remote sensing can be combined with GIS to produce a better tool i n disaster management. For example, the Wellington Regional Council (WRC) in New Zealand has developed a comprehensive library of earthquake hazard maps.The data have been digitized and forms part of the WRC GIS. Black and white copies of the maps are faxed to media outlets, police and emergency services while GIS/GPS were utilized to monitor the daily spread of the fire, measure fire suppression actions and assess damage to structures and to natural and cultural sources.

Future of GIS Geographical Information System (GIS) is a technological tool designed to store, analyze and display geographical data so that a person reading a map can select data necessary for a specific project or task. The demand for GIS tools is constantly growing.Comparing to the early years of GIS one would dream up a new spatial widget, code it, and then attempt to explain to others how and why they ought to use it, nowadays GIS has been applied into various fields whether in data management, economic planning and development, agriculture, and public safety, whereas in future GIS application should be better than this and make jobs to be done more easily. Why is future of GIS valuable? One of the reasons is geographic information science as a new science that is used to design future information systems.Also, it is valuable as it generates expansion into new fields and application areas, discovering new uses and solving problems. In future, the scie ntific visualization and computer graphics will be increasingly integrated with GIS capabilities, especially animated and interactive maps. The potential of future of GIS is far beyond the other sciences for the tools. In today’s world, acquiring data for a new GIS is no longer a major problem. GPS has become a main source of new GIS data and comes increasingly from integrated GPS/GIS systems.Nevertheless, this GIS domain has always been the outdoors where GPS signals are strong and reliable. Thus this matter should be looked into that moving GIS indoors. We need techniques for the rapid, cheap, and accurate capture of 3D geometries and attributes, as well as efficient methods of determining indoor position. The market for solutions to the problem of moving GIS indoors and integrating the indoors and outdoors really holds an enormous potential. By developing GIS trends, knowing where everything is can be very possible.Take consideration during emergencies but not invading pri vacy of ones, tracking individuals using the technologies of GIS would be very useful. For instant, it would be much easier to search for the possible victims if every inhabitant of the Wenchuan area of China had been tracked prior to the May 2008 earthquake. Furthermore, shifting GIS from the relatively leisurely process of analyzing static data to a far more dynamic process of real-time monitoring and decision making can be possible in future also.A GPS navigation system, fed by sensors, might show the state of congestion of the road system in real time; an emergency manager might view the real-time situation of a disaster response; and a public health researcher might monitor the real-time state of a disease outbreak. Nonetheless, as the progress of future of GIS is developing, we should also take the major influencing factors on it either positive or negative into consideration.There are several positive influences of future of GIS that we can see, such as continuing hardware co st reductions and improved performance, improvements in storage capacities and performance, the improved capability and functional range of most software, the adoption of standards for GIS in many countries, the availability of a greater range of digital data sets, the greater recognition of GIS as valuable management tool, and also the perceived success of GIS in a number of varied fields.For the negative sides, the lack of government funding for basic research initiatives, too many systems are stand-alone applications having little incentive to progress, the necessary implementation procedures are very complex, data costs can be prohibitive, too frequently data is difficult to integrate because of structure, accuracy, scale, level of aggregation, as well as the legal concerns over the copyright of data. In conclusion, GIS can be very useful if researches of innovation and evolution can be made more.Of course, advantages and disadvantages of applications of GIS in future have to be concerned much so that it can be fully utilized and the consequence of GIS development can be minimized. Last but not least, there is one fact that is inescapable: the world of GIS has always been full of surprises, and there is every reason to believe the future will be just exciting!

It is argued that such failures are in direct result of inadequately vetting their globalization strategies. We offer an in depth discussion surrounding the globalization issue and the necessary strategies, followed by recommendations we believe could help reduce the prevalence of globalization failures. We open our discussion with a 2008 case study urging the company considering globalization to ask themselves a series of revealing questions. Providing real life examples, we go on to highlight several underlying pressures and challenges often associated with the process of globalization. An analysis of the strengths, weaknesses, opportunities and threats, often associated with a firm who is not prepared for globalization, is performed. The often intimidating global climate and several mixed assumptions surrounding globalization are discussed across a multitude of service industries. We continue by presenting three of Sun Tzu’s principles, as cited in The Art of Business, as we argue ways in which they are instrumental to any successful globalization venture, providing examples of firms who have historically and successfully applied the three principles. Several Christian values and how they are intertwined within the structural framework of a successfully globalized firm mentioned, noting the importance of a functional mission statement and several key characteristics to be explored before attempting the cross-border venture; ensuring global readiness. Finally, we offer several recommendations that we conclude are vital in addressing globalization preparedness, suggesting that with additional research, insight, and after fully vetting the related risks and rewards, the frequency of globalization failures would be significantly reduced. Case Overview Marcus Alexander and Harry Korine (2008), argue that many companies do not take the time to ensure that their globalization strategies were not â€Å"deeply misguided. † Believing that many of these failures could be avoided, Alexander and Korine (2008) recommend the company pondering globalization ask themselves three questions: 1. Are there potential benefits for our company? 2. Do we have the necessary management skills? and 3. Will the costs outweigh the benefits? Among the arguments made by Alexander and Korine is that which encompasses the pressures surrounding the globalization process. Alexander and Korine (2008), argue that companies going global in relation to various marketplace pressures are making serious mistakes, subsequently forced to undo their international investments, often involving the firing of senior management teams. Alexander and Korine (2002), offer up examples of failed strategies such as Dutch financial-services firm ABN Amro, Daimler-Chrysler, and AES – a U. S. based energy firm that despite operating in 29 countries on five continents, struggle to bring added value. The authors relate the struggles of deregulated industries to a â€Å"glocal† problem. That is to say that many â€Å"customer expectations, operating environments, and management practices of a globally standard service can vary greatly depending on location,† in example, citing the standardization of electricity flowing over power grids (Alexander & Korine, 2008, p. 107-109). Every industry has its own challenges with globalization. Issues within the service industry, such as Starbucks, for example, have been that profit margins are equivalent to about half of that which can be expected domestically. In the IT industry the protection of intellectual property rights has caused many companies to simply leave countries like India, while the failed integration of Daimler-Benz and Chrysler is a perfect example of a failed globalization strategy in the manufacturing industry (Alexander & Korine, 2008). In discussing some of the strategies that did work, such as GE, and Renault’s alliance with Nissan, Alexander and Korine caution against focusing on these success stories. Stating that that while many companies are planning rapid expansion, they are underestimating the management challenges. Their final point is that the landscape of players is very different than that of the global landscape of 30 years ago. Today’s successful global behemoths, according to Alexander and Korine (2008), are more diversified â€Å"both in type and international footprint. † Meaning, such companies possess a greater diversity in the types of subsidiaries they own and operating in more countries than ever before. SWOT Analysis – When you Shouldn’t Go Global Strengths Reduced financial, political, currency, and exchange risk- Foreign investment involves all of these risks. By refraining from foreign investment we avoid these risks. Simplicity of operations- Setting up and maintaining foreign investments complicate operations. Refraining from going global keeps operations more simple. Protection of intellectual property- It is very difficult to protect intellectual property in foreign countries. By keeping all activities domestic, one is adding a layer of protection to intellectual property rights. Weaknesses Loss of economies-of-scale and economies-of-scope- This according to Alexander and Korine is what is not being fully realized by going global, and therefore may not be that significant of an issue in many industries. Loss of first-mover advantages- Choosing not to go global may mean making the irrevocable choice to give up the first-mover advantage. This is usually a very small window and a one-time opportunity. Foregoing additional revenue sources- For a company that has no additional potential revenue sources domestically, going global may be the only opportunity to gather additional revenue. Foregoing market growth- For companies wishing to expand market reach, the choice to forego going global will limit their market penetration. Opportunities No financial investment- Refraining from foreign financial investment frees-up those funds for investment in domestic activities. No use of other resources- Refraining from going global frees-up all resources (human, etc. ) for use in domestic activities. Threats Loss of market share to competition- Should one’s competition be successful in going global, they may be able to offer similar products at much lower prices thus forcing you out of the market. The competition may also offer superior products at higher prices, and capture the market, via the use of superior technology. Loss of talent to competition- In many fields, such as high tech and engineering, the worldwide competition for talent is fierce. Failure to go global often means failure to secure talent. Loss of learning opportunities- Since globalization can take the form of joint ventures. There is also the threat of the loss of learning from a joint venture partner that should be considered. Situation Analysis Since the seventh century business have possessed the desire to operate internationally however, those considered truly global, did not start appearing until the past century. With growing stories of globalization successes, follow just as many testaments to failures. Despite the growing number of failed attempts the overwhelming pressure to conduct the ultimate border-less business has become increasingly enticing. Most large companies founded 20 years ago feel battered by numerous external forces pushing them towards globalization. Driving forces such as the removal of political and regulatory barriers to global trading and investment and the ability to conduct business 24 hours a day from anywhere in the world, draw these business behemoths one step closer to customers in emerging economies (Alexander &Korine, p. 106). Deanna Julius (1997), lists in her article titled Globalization and Stakeholder Conflicts; a corporate perspective), three primary, macro-level forces, driving the need for change as; how companies are organized, how goods and services are produced and how they are bought by and delivered to customers. Alexander & Korine (2008), mention that while many of the companies that have rushed to globalization have benefited, or at the very least have not suffered irreparable damage, some are witnessing major fallout from the move. The authors suggest that while companies often fail from misguided global strategies and an unanticipated level of execution, they could have avoided such failure by seriously addressing if potential benefits even exist in going global, if their management possess the necessary skills and the most logical one, will the costs of going global outweigh the benefits? Alexander & Korine (2008), argue that most companies fail to ask themselves these questions due to previously held false assumptions regarding the virtues of globalization and seduction from the stock market. As previously mentioned, deregulated industries such as those who provide water, power, and mail service are among those experiencing global failure. Alexander & Korine (2008), suggest that deregulated industries are operating under the misguided assumptions as well. The greatest assumption being that, going global will save them money, given they will be sharing resources across their international operations. When in reality, the costs to enter the foreign markets end up outweighing the assumed benefits (Alexander & Korine, 2008, p. 107). Managerial fads are suggested to undermine rational behavior from within a company, thus resulting in sloppy thinking that distracts management from more imperative tasks associated with global success. Properly servicing global customers from a national perspective contributes too many failures given, much attention must be afforded to a mix or global and local factors simultaneously. Global manufacturing companies are said to fail due in part to the complexities related to the integration tactics necessary grow and compete better, resulting in costly delays and thus failures (Alexander & Korine, 2008, p. 110). STAB Principles Win All without Fighting – Capturing Your Market without Destroying It The goal of business is to survive and prosper over a long period of time. Sun Tzu, author of The Art of War, described the strategy in achieving this long term prosperity as an offensive one in which a company must take all under Heaven intact, â€Å"Thus your troops are not worn out and your gains will be complete (McNeilly, 1996, p. 11). McNeilly (1996), utilizing Sun Tzu’s principles in his book The Art of Business, adds that, by taking all under heaven intact you will capture your marketplace thus ensuring your company’s survival and prosperity. However, your desired markets must be defined as such and nothing less than commitment in achieving market dominance must be displayed (McNeilly, 1996, p. 1). Application of Sun Tzu’s principle, win all without fighting – capturing your market without destroying it, as cited in McNeilly (1996), has been useful to many of today’s leading companies, including global cement producer, CEMEX. Cemex’s CEO Lorenzo Zambrano has applied Sun Tzu’s technique when expanding his cement company in Mexico and abroad. By the year 2000, CEMEX had become the world’s third largest cement company. In Cemex’s quest for market dominance they switched to a strategy of growth through acquisitions. In the late 1980’s large firms were considering expanding their operations into Cemex’s Mexican territory. Realizing the imminent threat CEMEX decided to unify its Mexican operations by acquiring two of Mexico’s large cement producers, affording CEMEX access to Mexico’s central market and bolstering its exporting capabilities, making CEMEX Mexico’s largest cement producer and a threat not to be competed against. While CEMEX won all without fighting, they gained market dominance in Mexico, later fueling their geographic expansion (Ghemawat, 200, p. 155). Deception and Foreknowledge – Maximizing the Power of Market Information Foreknowledge, as described in Sun Tzu’s third strategic principle, is not projecting what will happen in the future, based on past occurrences or merely conducting a trend analysis. Foreknowledge and maximizing the power of market information is to; gain firsthand knowledge of your competitions strengths and weaknesses, know their capabilities, culture and mindset, and obtain a deeper understanding of who their decision makers are and what their future goals and plans are (McNeilly, 1996, p. 0). As Sun Tzu stated in The Art of War, as cited in McNeilly (1996), regarding foreknowledge â€Å"What is called foreknowledge cannot be elicited from spirits, nor from Gods, nor by analogy with past events, nor from calculations. It must be obtained from men who know the enemy situation. † In order for a company to succeed on a global scale not only do the ins and outs of their competition need to be understood and plotted against, they must also know themselves; their own weaknesses, strengths, people and plans as well as the market in which they will be entering. A corporation lacking this level of foreknowledge should reconsider entering global markets until they better know themselves and their competition. Before Wal-Mart swept our nation, Sam Walton gathered vast amounts of information on his competitors, large and small, before he ever brought competition to their territory. In fact, before Wal-Mart took on then behemoth value retailer Kmart, it was the smaller, local mom and pop retailers that were seized up. Walton learned about the smaller retailers value chains and distribution methods, through foreknowledge, he attacked their weakest points, where they could not afford to compete, in costs and deceptfully defeated them where they did not expect it; in their own small, rural towns. Defeating the smaller retailers gained Wal-Mart the necessary market share to then surround urban Kmart. Wal-Mart, knowing that Kmart’s operating costs was on average 5% higher than theirs attacked Kmart at its cost structure, and won. Kmart was just not able to get under Wal-Mart’s five point advantage in operating costs (McNeilly, 1996 p. 25). In 2009, after waiting for a new government with a more ‘hopeful’ political environment and a well paired partnership with local market-savvy grocery retailer, Bharti, Wal-Mart utilizes foreknowledge and deception to enter India’s market. Historically however, Wal-Mart has been unsuccessful in several global markets such as Japan due to their inability to adapt to local markets and tastes (Consumer Goods, 2009). As McNeilly (1996), notes in summary, you must learn everything you can about your competition, not merely the facts, but you must also learn about its culture, market, mindset and capabilities. Possibly additional foreknowledge in these areas could be of great use to Wal-Mart. Character Based Leadership – Providing Effective Leadership in Turbulent Times Character based leadership is not only desirable but it is an attribute than often separates the globally successful firms from the rest. When a company first tries its business hand and people skills at cross-border trading, most of the times are turbulent ones and without effective and transparent leadership, going global can quickly escalate from intimidating to downright terrifying. When we think of character based leaders, often people like Chrysler’s Lee Iacocca, Steve Jobs (Apple), The Snyder family (In-N-Out burger), Dan Cathy (Chick-Fil-A), Eric Schmidt (Google) and Jim Skinner of McDonalds come to mind, but McNeilly (1996) reminds us that not only are leaders of this caliber unique, they can also be hard to find. It is of no coincidence than that we can more readily recall companies operating under less than character based leadership, faster than those with it. Companies like Nike, BP, Exxon (Valdez Oil spill) and even Carl’s Jr’s current CEO Andy Puzder, come to mind. Sun Tzu stated in The Art of War, as cited within McNeilly (1996), â€Å"The general who in advancing does not seek personal fame, and in withdrawing is not concerned with avoiding punishment, but whose only purpose is to protect the people and promote the best interests of his sovereign, is the precious jewel of the state†¦few such to be had. McNeilly (1996) suggests that leaders of this caliber are desirable given they put the needs of others before theirs, they have strong and well developed characters. Becoming such a leader is not easy and will require much sacrifice to: â€Å"Build your character, not just your image; lead with actions, not just words; Share employee’s trials, not just triumph s, motivate emotionally, not just materially, assign clearly defined missions to all, avoiding mission overlap and confusion and the make your strategy drive your organization; not the reverse† (McNeilly, 1996, p. 119). Jim Skinner, CEO for McDonalds and winner of the 2009 CEO of the Year award is greatly admired and willingly followed by his employees around the world and thus a great example of a character based leader attributing to McDonald’s global successes. Skinner, who began his career with McDonald's in 1971 as a grill cook was named CEO in 2004, at a tumultuous time for the company. Skinner acted quickly to turn the company around and in result between 2004 and 2008 McDonald’s revenues climbed 41. 1 percent in four years, and net income jumped by 81 . 3 percent (Top Executive, 2009). The top nominees for CEO of the year are judged by such criteria as; leadership, integrity, ability to outperform and for their commitment to employees. It was no surprise to those who knew and worked with Jim Skinner that he had excelled in every category. After receiving the award, Skinner acknowledged the support his leadership team, along with the entire McDonald's system, stating â€Å"Together, our franchisees, employees and suppliers make up what we call our three-legged stool, we succeed only when all three legs of that stool are strong, aligned and performing at the highest levels† (Top executive, 2009). In closing, Skinner noted that while the challenges of leadership have grown more complex in the multifaceted business climate, holding fast to fundamental principals will serve today's global business leader well (Top Executive, 2009). The character based leader of today’s successful global firm provides effective leadership in turbulent times, Sun Tzu refers to this as ‘moral influence’ stating in The Art of War, as cited within McNeilly (1996), â€Å"By moral influence I mean that which causes people to be in harmony with their leaders, so that they will accompany them in life and unto death without fear of mortal peril. Skinner possesses moral influence among his employees, an important principle that will undoubtedly advance McDonalds in global markets around the world. Christian Values At the minimum, companies poised for global success, will adopt a mission statement. Ideally, these companies will have a statement of values. One organization that is not on ly global, but transnational – World Vision International has a statement of values that serves as moral compass in decision making and strategic planning. It states that WVI’s values are to â€Å"Bring a Christian, community-based, child-focused HIV and AIDS response, reflecting God’s unconditional love for all people and the affirmation of each individual’s dignity and worth† (World Vision International, 2009, p. 2). It is these types of clear statements of vision that removes the guess work from the Christian Business Praxis model. Additionally, companies need to look at the characteristics of their organization and the values their leadership possesses to determine whether or not the decision to global is in the best interest of the organization. Some examples are: Benevolence- For many organizations benevolence is the primary reason for going global. This was certainly the case of bicycle manufactures and APU alumni ACIRFA, who after going on mission to Africa saw a need for transportation and found a way to meet that need. Stewardship- Stakeholder theory, which seems to dominate most modern business decision making, indicates that it is unethical to go global without first considering the impact on all of your stakeholders. Clearly, one’s shareholders are his or her primary stakeholders. However, one must be mindful of the fact the fact that the organization is also the steward of its employees. And, to that end the organization has a duty to plan responsibly and minimize risk to those employees. As such, it is important for organizations to ensure that they are balancing potential profitability with the potential of not serving some of those under their care. Collaboration- This is a particularly useful skill if an organization is considering joint ventures. If, however, the organization has found that that the leadership of the organization or the organization as a whole is particularly weak in this area this is an indicator that a joint venture is not ideal. Integrity- The challenge associated with integrity (assuming that your organization possesses a great deal of integrity) is that one doesn’t know the off-shore partners and vendors one’s organization will be dealing with. New relationships will need to be established, and with that trust will need to be cultivated. Management skill- For every ounce of management skill it takes to manage domestically it takes a pound to manage off-shore. This is because there is an entirely new set of challenges and risks. There are language barriers in many cases. There are currency fluctuations, political risks, supply chain issues, and a whole host of challenges that one may not have realized existed even with extensive due diligence. Passion- The type of passion we are addressing here is the type associated with buy-in. If all members of the executive management team have not bought-in to the idea of going global it is going to be very difficult to have a great deal of success. Leadership must be passionate about going global. They must be excited, and they must be convinced that this is the future of the organization for global efforts to be successful. Preparation- Preparation is the key to success in going global. It may be fine to start out by simply exporting a few items. However, as demand increases, organizations will find that the need for strategic planning and preparation will also increase. Should a company wish to enter into either a joint venture, licensing agreement or build facilities off-shore, extensive due diligence involving outside consultants will be necessary. Zest- As we have suggested, going global is not for the faint-at-heart. Leaders have to be willing to take risks, and moreover leadership should invigorate others. Going global is not an easy task, great planning and preparation are integral. There will be many challenges and many hurdles and in many cases there will be more reasons to quit than stay the course. Therefore, zest is a prerequisite for going global. Recommendations Before making the decision to go global, heed Alexander and Korine’s advice, and ask three questions of your organization: 1. Are there potential benefits for our company? 2. Do we have the necessary management skills? and 3. Will the costs outweigh the benefits? The answers to those three questions will give the organization a starting point from which to determine if going global is in the best interest of the organization as a whole. Next, ask the operational questions- Is going global necessary for the growth and/or survival of our organization? Is globalization worth the various risks involved? Can effectively and protect our intellectual property in a cost efficient manner? Will the complications surrounding operations be overwhelming? What do we stand to lose if we don’t go global and if we don’t who within our competition will? What possible ramifications exist at the expense of not going global? Are we losing out on a learning opportunity by not going global? Is there unsecured talent out there that we may miss out on by not going global? Then ask the company, how much the above is worth in terms of opportunity cost? If we don’t utilize our time and resources in going global, how then will we allocate said resources to growth? Then ask your company the values questions- Is going global a responsible and ethical management decision? Can we trust that we will find people of integrity in the global economy to do business with and if so, do we possess the necessary passion and zest to be successful at such as risky cross-border venture? In addition, have we well prepared, and will we continue to be, throughout every step of the process? After asking the above questions we recommend conducting a detailed SWAT analysis where all possible risks and rewards involved with going global are fully vetted, then establish that all Christian perspectives are clear and present and finally, if the decision to go global is made, go forward while applying Sun Tzu’s Art of Business principles. In conclusion, Alexander and Korine (2008), suggest that we should not expect the influx of globalization failures to stop or improve any time soon. Making the valid point that, companies in a variety of industries will continue on in their reckless pursuit of global strategies, activists will continue to cause change and disruption and less than character based leaders will stand behind flawed globalization strategies, all the while, customers will always be demanding select attention. While it is undeniable that globalization is a seductively daunting opportunity with promises of increased power and unlimited benefits looming about the mere thought and that while even the best and brightest leaders, heading up the most well prepared companies may eventually succumb to its pressures, make the cross-border transition and possibly fail at it, keep in mind- sometimes to fail is necessary to succeed.

International Business - Global Marketing Essay Example | Topics and Well Written Essays - 750 words

International Business - Global Marketing - Essay Example Most firms will be reluctant to enter countries that have high political risks unless the potential returns are high or when countries with high political risk are providers of raw material that are in short supply. Thus, inflation rates, balance of payments, exchange rate stability, government budgets and the record of growth will be considered to evaluate the prospects for economic instability or crisis. Environmental scanning, strategy development and consistent market and global industry monitoring are the main steps for successful operation oversees (Keegan, Green, 2003). 2. The organizational theory/management has a long history goes back to ancient times. The main stages of management history development coincide with the traditional stages of historical development. The first is the Ancient history including Sumerians, Egyptians, Babylonians (Hammurabi's Code), Hebrews (Jethro), when private merchants appeared. Scalar and Exception Principles were the core of management. It is possible to include the primitive stage into this classification, when collecting and primitive trade (interchange) existed, but this management process was not conscious, but rather intuitive. In Ancient East, China developed management thought based on a class principle (division of labor), generic and distinct management styles. Further, Alexander the Great developed a staff principle. During Medieval Period delegation principle and Mercantilism were developed. In their works Machiavelli and Thomas More discussed the principle of ideal organizational structure. Industrial period has lasted from 1765 to present time. This period is marked by a free market system of production, corporate culture and integration (R. Owen, A Ure). The XX century has evolved the main concepts of contemporary management practice utilizing the previous knowledge (Keynes). (Minor, 1995). 3. a). A company should use international division when it achieves competitive advantage in a national industry and requires executives and managers to maintain a well-defined strategic focus abroad. Their task is to guide marketing efforts, coordinate and direct activities and monitor economic environment of a country to predict possible opportunities and threats. International division will be able to maintain a strict control over trade and administrative activities in a foreign country, and reach wider target audience implementing advertising and promotion activities. A single organizational unit will help to deal with special environment of a foreign country. The international division cannot solve the problems of another layer of management if its budget is inadequate to this task. It cannot solve the problems outside its regional location (Keegan, Green, 2003). b). Global product structure is often considered as a separate marketing context requiring adaptations of the product, its price and the way it is promoted to account for differences in cultural expectations or constraints imposed by the governments of nation states. Geographic approach allows a firm to select particular markets similar to their organizational arrangements, which help to avoid a failure if products are not tailored to local markets. Such differences have led many firms to appoint local agents in different countries to

Self Evaluation in Business law - Essay Example The paper is done using the Harvard referencing system and proper in-text citation and bibliography is provided. There is also a list of appendices used in the research report. Familiar cases and ruling have been applied appropriately, for example the case of in liability for allergic reaction of goods purchased under the sale of goods agreement. Most importantly has been submitted in good time. Last but not least the answer provide in different question have demonstrated that reasonable reach has been conducted and there is understanding of the Sale of good Act of 1974 and the Consumer Credit Act. It is one thing knowing about the Acts, and it is another thing being able to apply the provisions in handling complex real situations.Under the Sale of Goods Act, Julia has a right to complain to the seller of the washing machine. It is the buyers duty to inspect goods once there are delivered and to notify the seller of any faults within reasonable time. Some products have warranty perio ds but the Sale of goods act stipulates that the rights of a buyer can not be curtailed by simple warranty terms and conditions. A buyer has the right to inspect goods within reasonable time and place before accepting them. Generally, a buyer who finds goods purchase too be faulty is entitled with the responsibility to proof that the goods were faulty at the time of purchase. This way, a buyer can request for a full refund. Had Julia inspected the washing machine before six months, it would have been agreed that the machine was fault at the time of sale. However, Julia has reasonable circumstances as to why she did not return the machine earlier. She was traveling and thus had no time to inspect the machine. Julia was not in position to inspect and check the washing machine when it was delivered because she was called immediately the machine was delivered to an emergency and was away for 6 months. Her responsibility in this case is to just proof that the machine was not in satisfact ory condition at the time of purchase because she has never used it even once. It is her right as a consumer to get goods of acceptable standard and that are fit for their purpose (National Consumer agency 2011). It is now Julia’s responsibility to act promptly. She can seek refund, replacement or repair under the sale of goods Act. Oliver bought a luxury deep filled duck –down pillow so he would sleep well. However, he did not ask the sellers for man –made fibre pillow. The sellers were unaware of his allergy reactions to feather. Therefore, the sellers acted in good faith while selling Oliver the luxury pillow; he wanted to sleep well and he never told them about any problems with feather. The seller’s responsibility under consumer Act was to let the buyers know that the pillow had feather in it. The case would have been different if Oliver had told the seller that he was allergic to feather. Then, he would have statutory rights to be compensated for the harm suffered and may get another feather free luxury pillow. The product was not faulty or defective, it is just that he was allergic and other buyers may be not allergic. In the case of Adelman-Tremblay V.Jewel Companies, Inc in 1988, it was

Case Study Analysis Google Inc. in China Term Paper

Case Study Analysis Google Inc. in China - Term Paper Example Compliance to Chinese law conflicts the process of conducting a successful business model for companies such as Google. When attempting to circumvent various govern-ment-sanctioned filters, consumer freedoms are at risk from authorities charged with Web surveillance. Concurrently, defying sanctions that are not aligned or considered appropriate for Western nations such as the United States can lead to significant business disruption if (or when) the government demands complete deconstruction of Internet services such as Google. Thus, personally speaking, the regulatory environment in China creates a conflict of interest within the business model as it pertains to providing excellence in service and maintaining a filtered Web presence that does not sustain revenue growth or even brand reputation. B. State what you are bracketing:5 Â ¶ Personal values associated with a firm belief in the democratic process and consumer independence must be removed to avoid bias when analyzing the case study. The socialist doctrine that has replaced long-standing communist values would, according to various theories, be associated with promoting liberties for consumers and giving them more ownership over business and personal lifestyle. An enduring and genuine distaste for oppressive regimes must be bracketed to avoid incorporation of personal values associated with analysis of the case study. II. The Situation6: A. List the facts7 relevant to the issue(s) identified: Â ¶ Deciding whether to defy regulatory authorities to provide a richer and more liberal Internet experience is conflicted by the high volume of policing officials dispersed throughout China. The sophistication of Chinese filtering poses many risks to a business model that is designed to extend breadth of knowledge to consumers, having built this capacity in a free nation where such issues are not a business risk. From human capital to technologies, non-compliance to regulatory demands is going to be noticed by gov ernment regulatory forces and, thus, businesses providing Internet content cannot avoid these filtering obligations if the business is to remain sustainable in a foreign nation. B. List the facts that comprise the historical context relevant to the issue(s) identified: Â ¶ The physical structure of the Internet in China that was developed since allowing Internet services in 1999 provides ample opportunities for enforcement of laws associated with content sanctions. Furthermore, recruitment of private citizens in the enforcement and reporting processes seriously conflict attempting to avoid establishing government-mandated controls and filtrations and expanded the reach of enforcement against these laws. The totalitarian regime in China is long-standing, developed under previous communist-oriented government frameworks. The Chinese government also was not forthcoming in establishing clear and concise frameworks to define compliance to Internet censoring. Lack of clear language made the process of complying with laws, while also attempting to improve profitability in China, created a need for innovation at Google to satisfy

Toyotas Position in the Automobile Industry Research Paper

Toyotas Position in the Automobile Industry - Research Paper Example The competencies are responsible for the growth of an organization’s core products which in turn support the growth of other business units. Eventually, the business units are responsible for the production of the end products. This has been the case of Toyota. Toyota is among the most successful businesses in the global car manufacturing market. The success of the company is attributed to its core competencies and capabilities.   Toyota entered the vehicle manufacturing market with the few competencies and low capabilities that saw the company manufacture small volumes of cars annually. In 1947, the company could only manage to manufacture 100,000 cars only. The company was small in size and had limited resources and capacity to produce significant volumes for its market. This situation was compounded by the fact that the company was a new entrant in the car manufacturing market. However, the company made the first step towards growth by creating a team of visionary manager s that had competent skills in the manufacturing of cars and the management of the company in the new Japanese market. The operations of the company were directed by the exceptional skills of the founder. The founding team has been at center of the management of the company because of the management principles that they managed to establish when Toyota was making entry into the car manufacturing industry.   In terms of effectiveness, the company produces such large volumes but still maintain quality.  For instance, in the year 1962, the company was taking 15 minutes to change dies but the time was later reduced to only 3 seconds in its current production process.  

From the book 'TO KILL A MOCKINGBIRD - tHE SCOURGE OF RACISM Essay

From the book 'TO KILL A MOCKINGBIRD - tHE SCOURGE OF RACISM - Essay Example â€Å"Killing a Mocking Bird† set his background in the Alabama state during the depression and sort to find out the hardships that the black and other minority groups faced at the helm of this depression era. The relationship between the races at this era is depicted as being very wanting given the fact that the novel portrays the way the black race was victimized by the whites. The Tom Robinson trial just portrays the nature of prejudice that took place given the fact that when Atticus protected Tom, he was accused of being a nigger lover. The white jury refuses to accept the fact that Tom is innocent just because his testimony was pitted against that of a white person. This shows the amount of injustice offered to minority groups and then there’s the fact that the blatant testimony given against the evidence of Tom is taken as the judging clause to sentence him to death (Bloom, p.143). Atticus wants to reveal the truth to his fellow race, expose their discriminative racial comments, and encourage them to imagine the possibility of racial equality and an integration of the two races. The very moment that a person is just sentenced to death just because his case is against a perso n of a different race that sits at the jury, shows how discriminative the white people were in terms of justice offered to other races. What Atticus portrayed was a will to fight even when you new that you could not win. The whites describe the black community as trash. This is evident when Mr. Ewell threatens to kill Atticus just because he was on a black man’s side. He tries to kill Jem and Scout one night to get his revenge but the tables turn around and he ends up dead. For the first time, the sheriff declares a black person innocent. According to the author, in the court room there was a balcony for the black population which implies that the two races were not to stay together. As Atticus puts it in the book during his closing remarks in the Tom Robinson case, he acknowledged

Comparison of J.S. Bachs Fugues Essay Example | Topics and Well Written Essays - 500 words

Comparison of J.S. Bachs Fugues - Essay Example This was Bach's training ground. Bach's professional career commenced in 1700 as a chorister in Luneburg, followed by positions as an organist in Arnstadt, Muhlhausen, and Weimar up until 1717. It was his appointment in the ducal court at Weimar in 1708 where he started to compose fugues using contrapunctual 1techniques. In 1707 he composed the Little Organ Fugue in G minor (BWV 578), also known as the "Little Fugue" or "Little G minor". This music was originally written for the organ. As a typical fugue, the music commences with a brief musical theme, so called its subject, represented by a lone musical voice. This first voice continues and another enters to play the subject. Other voices enter one by one until there are several independent musical voices at play, developing the piece of music. The Little Fugue starts the subject in a minor key, but ends in with a (G) major chord, which was characteristic of Baroque fugues of the time that were written in the minor keys. Bach composed "The Art of Fugue", or "Die Kunst de Fugue" (BWV 1080) in 1748-1749 in Leipzig, where he was the Kantor 2of St Thomas's.

Treating Tobacco Dependence Essay Example for Free

Treating Tobacco Dependence Essay The article aims to reveal the connection between tobacco dependence, smoking cessation, and depression, in mentally ill health patients, especially those who have been previously diagnosed with unipolar depression. According to previous studies, smoking cessation causes depression in individuals who have suffered from the condition previously. Moreover, statistics gathered from comprehensive data analysis and research show that most individuals suffering mental conditions are highly dependent on tobacco use, which poses detrimental effects on their health. Resolutions in order to stop mental health patients or individuals previously diagnosed with depression from smoking, is yet to be discovered due to the absence of comprehensive information of how to handle relapse after smoking cessation. Since then, the treatment of tobacco abuse has become difficult since individuals with mental health conditions or who were previously diagnosed with depression, since undergoing smoking cessation, have worsened their present mental health functioning or have influenced them to revert to their previous depressive conditions. Another study conducted by Glassman et. al. on 100 individuals who were found out to have history of depression resulted to similar outcomes. They were administered with setraline, which was utilized to inhibit individuals from smoking and eventually help them get over the addiction. Majority of the sample population obtained for the study relapsed into their depressive state. The study conducted by Tsoh et. al., on the other hand, revealed that almost half of the sample population who were involved in smoking cessation also returned to their previous depressive state. If individuals who previously suffered from depression depend on tobacco use to repress depressive symptoms, then they would doubly suffer if smoking cessation were administered as a means of ending tobacco use. The particular study aimed to identify the extent of damage for individuals who depend on tobacco use and the effects of smoking cessation shortly after. The research studied and observed 322 individuals who are highly dependent on smoking, and who were previously diagnosed with unipolar depression. The individuals who were asked signed up and participate in the research were allowed by the mental health outpatient clinics, following up consent from these institutions. The particular research utilized a computer program designed to accomplish the purpose of the study. The computer program was employed to provide feedback for the changes in the behavior of an individual regarding smoking as they were monitored for a particular period of time. Individuals who took part in the research study completed the program from baseline, the third, sixth, twelfth, and eighteenth months following smoking cessation. The feedback generated for each program completion was based on previous data gathered from the individual. The standard for individuals who quit smoking was based on the individual’s abstinence from smoking for a seven-day period. To measure the results when it comes to mental conditions, the Beck Depression Inventory-II, Mental Component Summary of Medical Outcomes Study Short Form, the State-Trait Anger Expression Inventory. The results of the study were analyzed by utilizing a table, which monitored the mental health functioning of individuals as they commenced with smoking cessation practices. As the time progresses, the feedback generated by the computer program utilized in the study revealed that, individuals slowly showed signs of quitting from smoking. Some individuals reverted to alcohol and drug abuse, while some also lessened their use of drugs and alcohol. Only a small portion of the total population successfully quit from smoking. The results of the study were taken vis-à  -vis the findings of another study conducted by Hall and et. al. The study showed that individuals who are presently undergoing serious mental health conditions, such as depression, could be possibly assisted to undergo smoking cessation. This process, of intervention while experiencing mental health conditions would not hold negative effects upon recovery. Moreover, on a positive note, those who were found out to have successfully quit smoking also lessened their intake of alcohol, drugs, and other substances that led to addiction. The most significant outcome of the study reveals that both groups of individuals, mentally ill patients who underwent smoking cessation and abuse intervention, and those who successful quit smoking did not manifest any symptom of depression. Therefore, the study strongly supports intervention while patients are under care for mental health problems, rather than waiting for the depressive state to subside. This study greatly contributes to previous studies conducted in order to determine smoking cessation and its influence to patients with mental health problems that are highly dependent on tobacco use. Although the problem still lies with individuals who depend on tobacco use, and have suffered depression previously, and smoking cessation, there should be certain regulations and interventions prior to the elimination of mental health functioning. For instance, mental health patients should not be allowed to revert to smoking in order to suppress their depression. Mental health clinics should implement more programs and activities that are interesting and are more prone to relieve the stress of the patients in order to revert their attention from smoking cigarettes. This measure is an efficient way of influencing greater effects on the mental health of individuals, and also to save cost and effort on the part of mental health clinics, once previous patients relapse into their depressive states.          References Prochaska, J.

Effect of CR Supplementation on Athletic Performance

Effect of CR Supplementation on Athletic Performance Introduction To succeed in a given sport at any level of competition, athletes must possess specific physiologic, psychologic, and biomechanic traits critical to success in that sport, but they must also receive optimal physical, mental, and biomechanical training to maximise this genetic potential (Williams, Kreider Branch, 1999). However many athletes believe that the combination of genetic traits and optimal training alone are not sufficient to achieve maximum performance, therefore the use of ergogenic aids has become common to improve sports performance beyond the effect of training (Sundgot-Borgen, Berglund Torstveit, 2003). The use of ergogenic aids will allow athletes to gain that competitive advantage over opponents therefore leading to potential success. According to Williams, Kreider Branch, (1999) ergogenic aids are substances or treatments that are theoretically designed to enhance physical power, mental strength or mechanical edge therefore potentially improving athletic performa nce. Given the various demands of team sports such as Soccer, Rugby and Hockey, which require short intermittent bouts of high intensity exercise which are interspersed by low level exercise, it seems feasible the use of ergogenic aids in such sports may enhance and benefit performance to gain that competitive edge over opponents. One ergogenic aid which has become popular among amateur, professional and recreational athletes over recent years is Creatine Monohydrate (Cr). Creatine is a naturally occurring amino acid derivative which is found in skeletal muscle, but is also a normal dietary constituent with a daily requirement of approximately 2 to 3 grams depending on body size (Ostojic, 2001). The majority of creatine in muscles is stored in the form of phosphocreatine (PCr) which serves as an important contributor to energy metabolism during high intensity exercise (Williams, Kreider Branch, 1999). PCr provides the high energy phosphate for adenine diphosphate (ADP) to restore adenine triphosphate (ATP) concentration rapidly via the Cr kinase (CK) reaction (Clarkson, 1996). Hultman, Bergstrom and McLennan-Anderson, (1967) demonstrated that depletion of PCr stores within the muscles can lead to a decline in athletic performance during high intensity exercise, so theoretically increasing PCr stores through Cr supplementation would enhance the ability to maintain high intensity exercise over a prolonged period of time, leading to increases in sporting performance. Ahmun (2005) and Hultman, Soderlund, Timmons, Cederblad, Greenhaff, (1996) demonstrated that the average Cr concentration in human muscle can be increased through Cr supplementation over a 7 day period from 20% pre Cr to 50% post Cr. Since PCr is a substrate for the ATP-PCr energy system which is essential for high intensity exercise of 30 seconds or less it seems logical that the supplementation of Cr would be beneficial to exercise tasks of this duration. Therefore the majority of previous research has focused on bouts of anaerobic performance of To date the effect of Cr supplementation on athletic performance has been widely researched. This includes include positive effects of Cr supplementation over a prolonged period of over 4 weeks which is otherwise known as the maintenance phase (Knehans, Bemben, Bemben and Loftiss, 1998; Larson, Hunter, Trowbridge, Turk, Harbin and Torman, 1998). Also demonstrated have been positive effects of Cr supplementation on exercise performance using a shorter ingestion period known as the loading phase (Stout, Echerson, Noonan, Moore, and Cullen, 1999; Volek, Boetes, Bush, Putukian, Sebastianelli and Kraemer, 1997a). This includes improvements in performance variables such as strength, speed and delaying the onset of fatigue (Okudan and Gokbel, 2004; Volek, Kraemer, Bush, Boetes, Incledon, Clark and Lynch 1997b; Kocak Karli , 2003) Team sports consist of repeated bouts of intermittent high intensity exercise therefore consistently relying on the ATP-PCr energy system which if depleted can have a major factor on performance and the outcome of a game (Ostojic, 2004). One such sport which consists of repeated bouts of high intensity exercise is soccer. Soccer players are required to produce high power outputs and maintain or repeat them with only a few seconds of recovery, (Reilly and Williams, 2003). Such high intensity instances could be the deciding factor of a game, for example sprinting back to make a game saving tackle or sprinting past a defender to the ball to make a shot. One high intensity exercise instance which occurs in a soccer match are bouts of sprinting, which are estimated to consist of 8.1% of a 90 minute match and occur approximately every 90 seconds lasting between two to four seconds in duration (Bangsbo, Norregard Thorso, 1991). Given the fact that there is considerable support for Cr as an ergogenic aid it would be reasonable to suggest that a soccer players sprint performance would benefit from Cr supplementation. However there is minimal research which has looked into the effects of Cr on sprint performance and variables of soccer match play such as agility running, lateral stepping and running backwards( Cox, Mujika, Tumilty and Burke 2002; Ostojic, 2004; Mujika, Padilla, Ibanez, Izquierdo and Gorostiaga, 2000). The aforementioned studies have determined the effects of Cr on elite soccer players, female soccer players and youth soccer players (Ostojic, 2004; Mujika et al., 2000; Smart et al 1998; Cox et al., 2002). However there is no present research that looks into the effects of acute ( Another aspect to consider upon testing the effects of Cr on sprint performance on amateur soccer players is the protocol to be used. Although there have been many protocols which have been designed to measure and simulate soccer performance, plenty of these have failed to adequately simulate the different movement patterns (sprinting, walking, running backwards, lateral stepping) which are involved in a game of soccer (Drust, Reilly and Cable, 2000; Abt, Reaburn, Holmes and Gear, 2003; Thatcher and Batterham, 2004). It seems rational that when assessing components of soccer performance that the protocol that is utilised replicates the different activity patterns and demands of soccer match. If this is not taken into consideration it becomes difficult to determine whether Cr supplementation will have any benefit on soccer performance. Therefore the utilised protocol needs to concisely replicate movement patterns in soccer so that a valid assumption can be made to determine the erogen eity of acute Cr supplementation on sprint performance in amateur soccer players. Thus the purpose of this study is to conduct an investigation that will determine the effect of acute Cr supplementation on sprint performance in Caucasian male amateur soccer players, using a soccer simulation protocol in an accurate, valid and reliable manner with two trials consisting over a 7 day period. Concluding whether or not acute Cr supplementation can be used as an ergogenic aid to improve a footballers sprint performance, therefore recommending to athletes and coaches alike. Literature Review Creatine Monohydrate: Background Creatine monohydrate is one of the most popular sporting supplements in the world today and is used by high school athletes, the elderly, professional and recreational athletes in the hope of improving physical performance (Bemben and Lamont, 2005). It is the most commonly available Cr supplement and the form primarily used in most research studies. Cr monohydrate comes in a number of forms including powder, tablets, gel, liquid, chewing gum and candy (Williams, Kreider and Branch, 1999, p.43). Greenhaff (1997) indicated powdered Cr, ingested with solution to have a quicker absorption rate at raising muscle Cr concentration than using Cr supplementation of a tablet form. Conversely Vuckovich and Michaelis (1999) reported no significant difference in absorption rate between the two different forms. Dosage methods The supplementation dosages of Cr can be broken down into two different phases, otherwise known as the loading phase and maintenance phase. The loading phase that is commonly used in research consists of ingesting daily, 20-30g of Cr in four equal doses of 5-7g dissolved in around 250ml of fluid interspersed throughout the course of the day (preferably morning, noon, afternoon and evening) for a period of 5 to 7 days (Greenhaff, 1997; Kreider, 1997). Hultman et al (1996) utilised a less intense loading method of 3g/day for 28 days and proposed it to be just as effective as the aforementioned loading protocol. However this method places a longer dependency on subjects to comply with the supplementation program, therefore placing more variables into the reliability of results. Following the loading phase, maintenance dosages are considerably lower. Most research investigating the effects of Cr using the maintenance phase, have utilised dosages of 3 to 15g over a 4 to 10 week period (Bemben et al., 2001; Kreider et al., 1998; Stone et al., 1999; Vandenberghe et al., 1997). It is recommended to consume Cr with warm water, as it facilitates the dissolving of the solution and also aid absorption (Harris et al., 1992). It should also be noted that the ingestion of caffeine during Cr supplementation eradicates its potential ergogenic effect (Vandenberghe et al., 1996; Van Leemputte, Vanstapel Hespel, 1997). Vandenberghe et al (1996) demonstrated that a control group that ingested Cr combined with caffeine to have a lessened ergogenic potential compared to a group that ingested Cr without caffein e during repeated bouts of high intensity exercise. Side effects There is no conclusive scientific evidence to suggest that Cr ingestion has any negative side effects utilising the proposed dosage methods ( Larson et al., 1998; Schroder, Terrados Tramullas, 2005). There is further evidence to support this as Kreider et al (1999) found no negative side effects in athletes who had been ingesting Cr for up to 3 years. Poortmans and Francaux (1999) demonstrated similar findings for athletes for taking Cr for up to 5 years. Only undocumented anecdotal reports have reported any adverse negative side effects through Cr supplementation, this includes gastrointestinal distress, muscle cramping and dehydration (Associated press 1997, 1998). Taking dehydration into consideration such anecdotal research can be scrutinised. Oopik, Timpmann and Medijainen, (1995) demonstrated that Cr supplementation increased body mass, while also reporting increases in total body water. Such findings signify that Cr supplementation may prevent dehydration rather than be a cause, due to the fact it can promote water retention. Cr supplementation has been demonstrated to increase body mass by up to 2kg over an acute period of time (Balsom et al., 1995; Becque et al., 1997). This could be recognised as a negative side effect for athletes that compete in weight control sports, as Cr ingestion may impede their ability to make regulated weight in a forthcoming event. This gives a consensus that athletes in such activities need to be made aware that although Cr can promote gains in strength and power, it can increase body mass. Physiology of Soccer Soccer players are frequently required to produce high power outputs and maintain of repeat them with only a few seconds of recovery (Reilly and Thomas, 2003). This includes intermittent bouts of kicking, tackling, turning, sprinting, changing pace and maintaining balance and control of the ball whilst under pressure from an opponent (Wisloff, Helgerud Hoff, 1998). To gain a scientific perspective of the different physiological demands of soccer performance, match and time motion analysis have been utilised (Bangsbo, 1994). This analysis has allowed researchers to determine the overall workload of players during a 90 minute match by calculating total distance covered, and the pattern of activities performed during a game (e.g. sprinting, cruising, walking etc). Movement patterns of Soccer It is estimated that the total distance covered during a 90 minute soccer match varies from 8.7km to 11.5km ( Bangsbo Lindquist, 1992; Ekblom, 1986; Ohashi et al., (1988); Reilly and Thomas, 1976; 1988; Rampini et al., 2007; Wade, 1962). The large variance in distances covered are due in part to the differing styles of play, levels of competition and skill level of the teams that were utilised (Luxbacher, 1997). Reilly (1994) documented the different activity patterns of elite outfield players from the English top division and other major national leagues in Europe and Japan using different methods of match analysis. Results found that a 90 minute match consists of 24% walking, 36% jogging, 20% cruising sub maximally (striding), 11% sprinting, 7% moving backwards and 2% moving in possession of the ball. The categories of sprinting and cruising are defined as high intensity exercise. In terms of distances covered the ratio of low intensity exercise to high intensity exercise during a soccer match is 7 to 1 denoting that the outlay of energy for soccer is predominately aerobic ( Reilly and Thomas, 1976). However the importance for high intensity bouts during soccer match play should not be underestimated. The timing of such a bout could be the defining factor of a game whether in possession of the ball or without the ball. Although work-rate profiles are relatively consistent for players from game to game it is the high intensity exercise which is the most constant feature (Bangsbo, 1994). The number of sprints reported in a soccer game varies greatly from 17 to 62 (Bangsbo et al., 1991; Mohr, Krustrup Bangsbo, 2003). This variance is largely determined by the positional role of the player. Findings by Reilly (1996) demonstrated that midfielders and strikers completed more sprinting bouts than centre backs or full backs therefore relying more on the anaerobic energy system. However if there is not a prolonged recovery period or an individual is not properly conditioned they will not subsequently recovery from high intensity bouts of exercise and fatigue will occur (Reilly, 1996). This is evident as Reilly (1996, p.72) documented that the majority of goals conceded during a soccer match occurred in the final ten minutes of play. A popular theory for this occurrence has been found to be mental fatigue or lapses in concentration from defenders (Reilly, 1996, p.72). However this can theory can be scrutinised as research found that the onset of fatigue in intermittent exercise such as soccer is caused by low muscle glycogen stores (Balsom et al., 1999). Acute Cr supplementation and sprint performance in team sports Athletes in team sports such as soccer, rugby, hockey and American football are required to repeatedly reproduce intermittent bouts of high intensity exercise with minimal recovery. Being able to consistently reproduce such bouts at maximal ability (e.g. sprinting, jumping, running backwards) could be the deciding factor in competition to gain that extra edge of an opponent. During high intensity exercise of an intermittent nature the main contributor of energy is PCr (Williams, Kreider Branch, 1999, p29). Depletion of PCr stores during high intensity exercise has been found to be a factor which has lead to a decline in athletic performance (Hultman, Bergstrom and McLennan-Anderson, 1967). Through the supplementation of Cr, it hypothesised that PCr stores are replenished at a faster rate therefore improving an athletes ability to recover and perform intermittent high intensity bouts of exercise, leading to improved athletic performance (Greenhaff et al, 1993). There have been various studies that have tested this hypothesis by investigating the ergogenic effect of acute Cr supplementation on sprint performance of athletes in team sports (Ahmun et al., 2005; Cornish, Chilibeck Burke, 2006; Izquierdo et al., 2001; Kocak Karli, 2003; Romer et al., 2001; Vandebuerie et al., 1998). However the aforementioned studies have contrasting findings with a quantity of studies finding a significant improvement in sprint performance through Cr supplementation (Izquierdo et al., 2001; Romer et al., 2001; Vandebuerie et al., 1998). On the contrary other studies have found no significant improvements in sprint performance through acute Cr ingestion (Ahmun et al., 2005; Cornish, Chilibeck Burke, 2006; Kocak Karli, 2003). Ahmun et al., (2005) investigated the ergogenic effect of Cr on sprint performance in male rugby players. For this study a Wingate test protocol was utilised prior and post Cr supplementation. Findings of this study were that there was no significant improvement in maximal cycle sprints through Cr ingestion. However in contrast Izquierdo et al., (2001) found that acute Cr supplementation improved sprint times in male hand ball players. For this study subjects were either assigned Cr or placebo over a 5 day period. The protocol that was utilised consisted of repeated sprint runs that were consistent with sprint distances achieved during handball match play. One issue that could have had a determining factor of the non significant results found by Ahmun et al (2005) is the protocol that was utilised. A Wingate test was utilised to test the sprint performance in rugby players, however the relevance of a Wingate test to measure rugby performance is not sports specific there scrutinising the validity of the results. In contrast Izquierdo et al (2001) utilised a protocol which successfully replicated distances found in handball match play therefore maintaining validity. Ahmun et al (2005) also failed to incorporate a dietary analysis into the experimental design of the protocol, therefore whether or not Cr stores within the subjects utilised were full cannot be determined, which gives rationale for results showing no significant improvement. In contrast Izquierdo et al (2001) implemented a dietary examination of subjects that were utilised; this was initiated to determine whether any subjects had ingested Cr or any ergogenic aids prior to baseline testing. This assisted with maintaining validity during research. This can be supported by Romer et al (2001) and Vandebuerie et al (1998) who utilised a protocol containing a dietary analysis and concluded a significant improvement in sprint times within subjects. Cr supplementation and Soccer performance Given the intermittent physical demands of soccer, which requires players to produce high power outputs and maintain or repeat them with only a few seconds of recovery, (Reilly and Williams, 2003) it seems feasible that soccer players would benefit from the supplementation of Cr as an ergogenic aid to improve their overall performance. However research that has investigated the effect on acute Cr supplementation on different variables of soccer performance and predominately sprint performance utilising a soccer simulation protocol is limited (Ostojic, 2004; Mujika et al 2000; Cox et al 2002). The Aforementioned studies have primarily focused on the effects of Cr supplementation on highly trained athletes that are competing at a high standard of competition. However no previous research has looked into the effects of acute Cr supplementation on amateur soccer players. Being as though Cr monohydrate is an immensely popular ergogenic aid not only among professional athletes but also amateur and recreational athletes, the benefit to amateur athletes needs to recognised. Previous research that has looked into the effects of acute Cr supplementation on soccer players using a soccer simulation protocol is discussed below. Ostojic (2004) examined the effects of acute Cr supplementation (3 x 10g doses for 7 days) on 20 young male soccer players (16.6 Â ± 1.9 years). For the testing procedure a double blind method was used and where subjects were either administered either Cr or placebo. Subjects completed two separate trials prior and post to Cr or placebo. The testing procedure consisted of a number of soccer specific skill tests which included a dribble test, sprint-power test, endurance test and a vertical jump test. Results found that there was a significant improvement in a number of the soccer specific tests; this includes superior improvements in sprint times, vertical jump scores and the dribble test. However no significant improvements were made on endurance performance after the two trials. Although a significant improvement was found in vertical jump performance, it is of concern to future researchers to whether the vertical jump test that was utilised during the design is a soccer specific test. During the test subjects were instructed to keep their trunk as straight as possible whilst keeping their hands on their hips to avoid contribution from the arms which doesnt successfully replicate jumping movements in soccer therefore questioning the validity of the vertical jump test as to whether or not it is a measure of soccer specific performance. The age of the subjects in this research can also be scrutinised. Eichner, King, Myhal, Prentice and Ziegenfuss (1999) confirmed that there was insufficient research to determine the acute and chronic side effects of Cr consumption in athletes under the age of 18 therefore places the subjects which were used in the mentioned study under possible risk. Eichner et al (1999) also highlighted that Cr supplementation in young athletes could have a possible degradation of ethics, by where a win at all costs mentality is fostered and an attitude by where ergogenic aids are necessary to win, which is the wrong message to be installing in young athletes. Likewise Mujika, Padilla, Ibanez, Izquerido and Gorostiaga (2000) concluded acute Cr supplementation (20g a day x 6 days) significantly improved sprint performance and found no significant improvement in endurance performance using a soccer simulation protocol. Mujika et al (2000) also documented no increase in vertical jump performance using a similar protocol to Ostojic (2004) which has minimal significance in a soccer simulation study. Mujika et al (2000) tested 19 elite male soccer players who at the time of investigation were highly trained, however only 17 fully completed the testing due to illness or injury. The protocol for this investigation consisted of a circuit of different exercises which consisted of a repeated sprint test (5 and 15m), vertical jump test and an intermittent endurance test. Findings in this study concluded that mean sprint times improved significantly (p This de-training effect is evident for the vertical jump test as no significant improvement between the two trials was found. However if there was a significant de training effect it would have had negative consequences on other testing variables such as sprint performance, this however is not the case as sprint performance significantly improved. Mujika et al (2000) should have took into consideration a possible detraining effect when devising the experimental design as this could have negatively affect the validity of the results. Cox, Mujika, Tumilty and Burke (2002) devised a study which tested Cr supplementation (20g a day) or placebo (20g glucose a day) on 14 elite female soccer players from the Australian institute of sport (AIS) using a soccer simulated protocol. The experimental design consisted of two trials before and after Cr or placebo over a 6 day period. The protocol consisted of fifty five 20m sprints, ten agility runs and a precision ball kicking drill which are separated by recovery walks, jogs and runs. The main findings in this study were that the average 20m sprint time in the Cr group decreased from 3.75 Â ± 0.19 to 3.69 Â ± 0.18s however this decrease in sprint time failed to reach the statistical significance level (p Cox et al (2002) also incorporated a standardised training regime and a controlled diet for the intervention week and also scheduled testing so that it would occur at the same time of day before and after supplementation. In contrast Mujika et al (2000) failed to utilise effective standardised procedures during their experimental design. As previously mentioned Mujika et al (2000) testing procedures took place 3 days after the subjects season had finished therefore training was not standardised due to the fact that subjects had no organised training sessions during the intervention week. Mujika et al (2000) also lacked a familiarisation trial, subjects were only familiarised with the testing procedures prior to arriving for the 1st trial which could substantially affect the results. However although Cox et al (2000) standardised procedures by included a controlled diet for the subjects, it is interesting to note that one of the subjects was a vegetarian, whos Cr content is virtually zero (Greenhaff, 1997). Research has found that vegetarians respond quicker and more effectively to Cr supplementation than those who follow a normal sedentary diet and have natural muscle creatine content (Burke, Chilibeck, Parise, Candow, Mahoney Tamopolsky., 2003; Watt, Garnham Snow, 2004) therefore scrutinising the validity of the results. It may be of future reference to eradicate vegetarians in a experimental design which utilises Cr supplementation due to the diet implications that vegetarians have. Soccer Simulation performance tests To date there has been a number of soccer simulation performance tests which have been utilised to assess and measure different physiological aspects of the game (Bangsbo and Lindquist, 1992; Cox, 2002; Drust, Reilly and Cable, 2000; Nicholas, Nuttall and Williams, 2000). These protocols have been implemented so that they take into consideration different aspects of soccer performance and try to replicate the exercise patterns that are observed during match play, however due to the spontaneity of the soccer it is difficult to assess every physical or metabolic demand (Drust, Reilly and Cable, 2000). Researchers have used different protocols when investigating the metabolic and physical demands of soccer, these can documented into laboratory based protocols (Drust, Reilly and Cable, 2000; Thatcher and Batterham, 2004) and field based protocols (Bangsbo and Lindquist, 1992; Cox, 2002; Nicholas et al 2000). Laboratory based soccer performance protocols Drust, Reilly and Cable (2000) devised a laboratory based protocol on a motorised treadmill what represented the work rates that are observed during soccer match play. For the experimental design 7 male university soccer players (24 Â ± 2 years) were used and the testing consisted of three separate testing blocks which were separated by 6 days. The protocol consisted of the different exercise intensities that are utilised during soccer match play; this consisted of walking, jogging, cruising and sprinting. The speeds at which these exercises were performed on the treadmill were consistent with speeds observed by Van Gool, Van Gervan and Boutmans (1988) during a match analysis. Each testing block consisted of two 22.5 minute cycles which consisted of 23 bouts which were followed by a recovery period of 71 seconds. During each bout the duration of each activity was as follows: walking 35 seconds (s), jogging 50.3s, cruising 51.4s and sprinting 10.5s. However in relevance to this research project it should be noted that the duration covered during the sprint bouts of the protocol of Drust, Reilly and Cable (2000) which is 10.5s does not successfully coincide with match analysis from several soccer studies that have documented the duration of sprint bouts during soccer match play. Research has found that the average sprint time during soccer match play lasts between on average two to four seconds in duration (Bangsbo, Norregard Thorso,1991; Mayhew and Wenger, 1985) therefore concluding in some instances Drust, Reilly and Cables (2000) laboratory based soccer specific protocol can be deemed as in valid as it fails to accurately replicate different soccer performance variables that take place in match play. Another lab based test that was utilised to measure specific variables in soccer performance was devised by Thatcher and Batterham (2004). For this protocol six male professional soccer players were used and the testing consisted of 29 minute exercise bouts on a non motorised treadmill that focused on replicating different speeds, durations, distances and heart rates that occur during soccer match play. Findings from this study suggest that the protocol that was utilised induced a similar physiological load to soccer match play and can be determined as a valid measure of soccer performance. Although lab based soccer specific protocols have been found to replicate some instances of soccer performance it is of consideration of this research project that the limitations and positives of such protocols be noted. The aforementioned lab based failed to perform a re-test procedure to conclude whether their protocols maintained reliability therefore the amount of error in each protocol cannot be determined. Another limitation of lab based testing is that due to tests being performed on treadmills, this limits the subjects to straight-line running only, therefore does not take into consideration lateral movements and agility patterns, which have found to be major characteristics of soccer performance (Bangsbo and Lindquist, 1992). These unorthodox movement patterns need to be taken into consideration when assessing soccer performance as they increase energy expenditure significantly (Nicholas et al., 2000). One positive aspect of lab based protocols are that procedures such as a ir temperature, equipment utilised and humidity can be easily standardised to remain constant throughout performance testing. Field Tests Nicholas et al (2000) devised the Loughborough Intermittent Shuttle test (LIST) to simulate the activity patterns during a game of soccer. The LIST consisted of two separate stages which were known as part A and part B. Part A lasted 70 minutes and consisted of five 15 minute exercise pe Effect of CR Supplementation on Athletic Performance Effect of CR Supplementation on Athletic Performance Introduction To succeed in a given sport at any level of competition, athletes must possess specific physiologic, psychologic, and biomechanic traits critical to success in that sport, but they must also receive optimal physical, mental, and biomechanical training to maximise this genetic potential (Williams, Kreider Branch, 1999). However many athletes believe that the combination of genetic traits and optimal training alone are not sufficient to achieve maximum performance, therefore the use of ergogenic aids has become common to improve sports performance beyond the effect of training (Sundgot-Borgen, Berglund Torstveit, 2003). The use of ergogenic aids will allow athletes to gain that competitive advantage over opponents therefore leading to potential success. According to Williams, Kreider Branch, (1999) ergogenic aids are substances or treatments that are theoretically designed to enhance physical power, mental strength or mechanical edge therefore potentially improving athletic performa nce. Given the various demands of team sports such as Soccer, Rugby and Hockey, which require short intermittent bouts of high intensity exercise which are interspersed by low level exercise, it seems feasible the use of ergogenic aids in such sports may enhance and benefit performance to gain that competitive edge over opponents. One ergogenic aid which has become popular among amateur, professional and recreational athletes over recent years is Creatine Monohydrate (Cr). Creatine is a naturally occurring amino acid derivative which is found in skeletal muscle, but is also a normal dietary constituent with a daily requirement of approximately 2 to 3 grams depending on body size (Ostojic, 2001). The majority of creatine in muscles is stored in the form of phosphocreatine (PCr) which serves as an important contributor to energy metabolism during high intensity exercise (Williams, Kreider Branch, 1999). PCr provides the high energy phosphate for adenine diphosphate (ADP) to restore adenine triphosphate (ATP) concentration rapidly via the Cr kinase (CK) reaction (Clarkson, 1996). Hultman, Bergstrom and McLennan-Anderson, (1967) demonstrated that depletion of PCr stores within the muscles can lead to a decline in athletic performance during high intensity exercise, so theoretically increasing PCr stores through Cr supplementation would enhance the ability to maintain high intensity exercise over a prolonged period of time, leading to increases in sporting performance. Ahmun (2005) and Hultman, Soderlund, Timmons, Cederblad, Greenhaff, (1996) demonstrated that the average Cr concentration in human muscle can be increased through Cr supplementation over a 7 day period from 20% pre Cr to 50% post Cr. Since PCr is a substrate for the ATP-PCr energy system which is essential for high intensity exercise of 30 seconds or less it seems logical that the supplementation of Cr would be beneficial to exercise tasks of this duration. Therefore the majority of previous research has focused on bouts of anaerobic performance of To date the effect of Cr supplementation on athletic performance has been widely researched. This includes include positive effects of Cr supplementation over a prolonged period of over 4 weeks which is otherwise known as the maintenance phase (Knehans, Bemben, Bemben and Loftiss, 1998; Larson, Hunter, Trowbridge, Turk, Harbin and Torman, 1998). Also demonstrated have been positive effects of Cr supplementation on exercise performance using a shorter ingestion period known as the loading phase (Stout, Echerson, Noonan, Moore, and Cullen, 1999; Volek, Boetes, Bush, Putukian, Sebastianelli and Kraemer, 1997a). This includes improvements in performance variables such as strength, speed and delaying the onset of fatigue (Okudan and Gokbel, 2004; Volek, Kraemer, Bush, Boetes, Incledon, Clark and Lynch 1997b; Kocak Karli , 2003) Team sports consist of repeated bouts of intermittent high intensity exercise therefore consistently relying on the ATP-PCr energy system which if depleted can have a major factor on performance and the outcome of a game (Ostojic, 2004). One such sport which consists of repeated bouts of high intensity exercise is soccer. Soccer players are required to produce high power outputs and maintain or repeat them with only a few seconds of recovery, (Reilly and Williams, 2003). Such high intensity instances could be the deciding factor of a game, for example sprinting back to make a game saving tackle or sprinting past a defender to the ball to make a shot. One high intensity exercise instance which occurs in a soccer match are bouts of sprinting, which are estimated to consist of 8.1% of a 90 minute match and occur approximately every 90 seconds lasting between two to four seconds in duration (Bangsbo, Norregard Thorso, 1991). Given the fact that there is considerable support for Cr as an ergogenic aid it would be reasonable to suggest that a soccer players sprint performance would benefit from Cr supplementation. However there is minimal research which has looked into the effects of Cr on sprint performance and variables of soccer match play such as agility running, lateral stepping and running backwards( Cox, Mujika, Tumilty and Burke 2002; Ostojic, 2004; Mujika, Padilla, Ibanez, Izquierdo and Gorostiaga, 2000). The aforementioned studies have determined the effects of Cr on elite soccer players, female soccer players and youth soccer players (Ostojic, 2004; Mujika et al., 2000; Smart et al 1998; Cox et al., 2002). However there is no present research that looks into the effects of acute ( Another aspect to consider upon testing the effects of Cr on sprint performance on amateur soccer players is the protocol to be used. Although there have been many protocols which have been designed to measure and simulate soccer performance, plenty of these have failed to adequately simulate the different movement patterns (sprinting, walking, running backwards, lateral stepping) which are involved in a game of soccer (Drust, Reilly and Cable, 2000; Abt, Reaburn, Holmes and Gear, 2003; Thatcher and Batterham, 2004). It seems rational that when assessing components of soccer performance that the protocol that is utilised replicates the different activity patterns and demands of soccer match. If this is not taken into consideration it becomes difficult to determine whether Cr supplementation will have any benefit on soccer performance. Therefore the utilised protocol needs to concisely replicate movement patterns in soccer so that a valid assumption can be made to determine the erogen eity of acute Cr supplementation on sprint performance in amateur soccer players. Thus the purpose of this study is to conduct an investigation that will determine the effect of acute Cr supplementation on sprint performance in Caucasian male amateur soccer players, using a soccer simulation protocol in an accurate, valid and reliable manner with two trials consisting over a 7 day period. Concluding whether or not acute Cr supplementation can be used as an ergogenic aid to improve a footballers sprint performance, therefore recommending to athletes and coaches alike. Literature Review Creatine Monohydrate: Background Creatine monohydrate is one of the most popular sporting supplements in the world today and is used by high school athletes, the elderly, professional and recreational athletes in the hope of improving physical performance (Bemben and Lamont, 2005). It is the most commonly available Cr supplement and the form primarily used in most research studies. Cr monohydrate comes in a number of forms including powder, tablets, gel, liquid, chewing gum and candy (Williams, Kreider and Branch, 1999, p.43). Greenhaff (1997) indicated powdered Cr, ingested with solution to have a quicker absorption rate at raising muscle Cr concentration than using Cr supplementation of a tablet form. Conversely Vuckovich and Michaelis (1999) reported no significant difference in absorption rate between the two different forms. Dosage methods The supplementation dosages of Cr can be broken down into two different phases, otherwise known as the loading phase and maintenance phase. The loading phase that is commonly used in research consists of ingesting daily, 20-30g of Cr in four equal doses of 5-7g dissolved in around 250ml of fluid interspersed throughout the course of the day (preferably morning, noon, afternoon and evening) for a period of 5 to 7 days (Greenhaff, 1997; Kreider, 1997). Hultman et al (1996) utilised a less intense loading method of 3g/day for 28 days and proposed it to be just as effective as the aforementioned loading protocol. However this method places a longer dependency on subjects to comply with the supplementation program, therefore placing more variables into the reliability of results. Following the loading phase, maintenance dosages are considerably lower. Most research investigating the effects of Cr using the maintenance phase, have utilised dosages of 3 to 15g over a 4 to 10 week period (Bemben et al., 2001; Kreider et al., 1998; Stone et al., 1999; Vandenberghe et al., 1997). It is recommended to consume Cr with warm water, as it facilitates the dissolving of the solution and also aid absorption (Harris et al., 1992). It should also be noted that the ingestion of caffeine during Cr supplementation eradicates its potential ergogenic effect (Vandenberghe et al., 1996; Van Leemputte, Vanstapel Hespel, 1997). Vandenberghe et al (1996) demonstrated that a control group that ingested Cr combined with caffeine to have a lessened ergogenic potential compared to a group that ingested Cr without caffein e during repeated bouts of high intensity exercise. Side effects There is no conclusive scientific evidence to suggest that Cr ingestion has any negative side effects utilising the proposed dosage methods ( Larson et al., 1998; Schroder, Terrados Tramullas, 2005). There is further evidence to support this as Kreider et al (1999) found no negative side effects in athletes who had been ingesting Cr for up to 3 years. Poortmans and Francaux (1999) demonstrated similar findings for athletes for taking Cr for up to 5 years. Only undocumented anecdotal reports have reported any adverse negative side effects through Cr supplementation, this includes gastrointestinal distress, muscle cramping and dehydration (Associated press 1997, 1998). Taking dehydration into consideration such anecdotal research can be scrutinised. Oopik, Timpmann and Medijainen, (1995) demonstrated that Cr supplementation increased body mass, while also reporting increases in total body water. Such findings signify that Cr supplementation may prevent dehydration rather than be a cause, due to the fact it can promote water retention. Cr supplementation has been demonstrated to increase body mass by up to 2kg over an acute period of time (Balsom et al., 1995; Becque et al., 1997). This could be recognised as a negative side effect for athletes that compete in weight control sports, as Cr ingestion may impede their ability to make regulated weight in a forthcoming event. This gives a consensus that athletes in such activities need to be made aware that although Cr can promote gains in strength and power, it can increase body mass. Physiology of Soccer Soccer players are frequently required to produce high power outputs and maintain of repeat them with only a few seconds of recovery (Reilly and Thomas, 2003). This includes intermittent bouts of kicking, tackling, turning, sprinting, changing pace and maintaining balance and control of the ball whilst under pressure from an opponent (Wisloff, Helgerud Hoff, 1998). To gain a scientific perspective of the different physiological demands of soccer performance, match and time motion analysis have been utilised (Bangsbo, 1994). This analysis has allowed researchers to determine the overall workload of players during a 90 minute match by calculating total distance covered, and the pattern of activities performed during a game (e.g. sprinting, cruising, walking etc). Movement patterns of Soccer It is estimated that the total distance covered during a 90 minute soccer match varies from 8.7km to 11.5km ( Bangsbo Lindquist, 1992; Ekblom, 1986; Ohashi et al., (1988); Reilly and Thomas, 1976; 1988; Rampini et al., 2007; Wade, 1962). The large variance in distances covered are due in part to the differing styles of play, levels of competition and skill level of the teams that were utilised (Luxbacher, 1997). Reilly (1994) documented the different activity patterns of elite outfield players from the English top division and other major national leagues in Europe and Japan using different methods of match analysis. Results found that a 90 minute match consists of 24% walking, 36% jogging, 20% cruising sub maximally (striding), 11% sprinting, 7% moving backwards and 2% moving in possession of the ball. The categories of sprinting and cruising are defined as high intensity exercise. In terms of distances covered the ratio of low intensity exercise to high intensity exercise during a soccer match is 7 to 1 denoting that the outlay of energy for soccer is predominately aerobic ( Reilly and Thomas, 1976). However the importance for high intensity bouts during soccer match play should not be underestimated. The timing of such a bout could be the defining factor of a game whether in possession of the ball or without the ball. Although work-rate profiles are relatively consistent for players from game to game it is the high intensity exercise which is the most constant feature (Bangsbo, 1994). The number of sprints reported in a soccer game varies greatly from 17 to 62 (Bangsbo et al., 1991; Mohr, Krustrup Bangsbo, 2003). This variance is largely determined by the positional role of the player. Findings by Reilly (1996) demonstrated that midfielders and strikers completed more sprinting bouts than centre backs or full backs therefore relying more on the anaerobic energy system. However if there is not a prolonged recovery period or an individual is not properly conditioned they will not subsequently recovery from high intensity bouts of exercise and fatigue will occur (Reilly, 1996). This is evident as Reilly (1996, p.72) documented that the majority of goals conceded during a soccer match occurred in the final ten minutes of play. A popular theory for this occurrence has been found to be mental fatigue or lapses in concentration from defenders (Reilly, 1996, p.72). However this can theory can be scrutinised as research found that the onset of fatigue in intermittent exercise such as soccer is caused by low muscle glycogen stores (Balsom et al., 1999). Acute Cr supplementation and sprint performance in team sports Athletes in team sports such as soccer, rugby, hockey and American football are required to repeatedly reproduce intermittent bouts of high intensity exercise with minimal recovery. Being able to consistently reproduce such bouts at maximal ability (e.g. sprinting, jumping, running backwards) could be the deciding factor in competition to gain that extra edge of an opponent. During high intensity exercise of an intermittent nature the main contributor of energy is PCr (Williams, Kreider Branch, 1999, p29). Depletion of PCr stores during high intensity exercise has been found to be a factor which has lead to a decline in athletic performance (Hultman, Bergstrom and McLennan-Anderson, 1967). Through the supplementation of Cr, it hypothesised that PCr stores are replenished at a faster rate therefore improving an athletes ability to recover and perform intermittent high intensity bouts of exercise, leading to improved athletic performance (Greenhaff et al, 1993). There have been various studies that have tested this hypothesis by investigating the ergogenic effect of acute Cr supplementation on sprint performance of athletes in team sports (Ahmun et al., 2005; Cornish, Chilibeck Burke, 2006; Izquierdo et al., 2001; Kocak Karli, 2003; Romer et al., 2001; Vandebuerie et al., 1998). However the aforementioned studies have contrasting findings with a quantity of studies finding a significant improvement in sprint performance through Cr supplementation (Izquierdo et al., 2001; Romer et al., 2001; Vandebuerie et al., 1998). On the contrary other studies have found no significant improvements in sprint performance through acute Cr ingestion (Ahmun et al., 2005; Cornish, Chilibeck Burke, 2006; Kocak Karli, 2003). Ahmun et al., (2005) investigated the ergogenic effect of Cr on sprint performance in male rugby players. For this study a Wingate test protocol was utilised prior and post Cr supplementation. Findings of this study were that there was no significant improvement in maximal cycle sprints through Cr ingestion. However in contrast Izquierdo et al., (2001) found that acute Cr supplementation improved sprint times in male hand ball players. For this study subjects were either assigned Cr or placebo over a 5 day period. The protocol that was utilised consisted of repeated sprint runs that were consistent with sprint distances achieved during handball match play. One issue that could have had a determining factor of the non significant results found by Ahmun et al (2005) is the protocol that was utilised. A Wingate test was utilised to test the sprint performance in rugby players, however the relevance of a Wingate test to measure rugby performance is not sports specific there scrutinising the validity of the results. In contrast Izquierdo et al (2001) utilised a protocol which successfully replicated distances found in handball match play therefore maintaining validity. Ahmun et al (2005) also failed to incorporate a dietary analysis into the experimental design of the protocol, therefore whether or not Cr stores within the subjects utilised were full cannot be determined, which gives rationale for results showing no significant improvement. In contrast Izquierdo et al (2001) implemented a dietary examination of subjects that were utilised; this was initiated to determine whether any subjects had ingested Cr or any ergogenic aids prior to baseline testing. This assisted with maintaining validity during research. This can be supported by Romer et al (2001) and Vandebuerie et al (1998) who utilised a protocol containing a dietary analysis and concluded a significant improvement in sprint times within subjects. Cr supplementation and Soccer performance Given the intermittent physical demands of soccer, which requires players to produce high power outputs and maintain or repeat them with only a few seconds of recovery, (Reilly and Williams, 2003) it seems feasible that soccer players would benefit from the supplementation of Cr as an ergogenic aid to improve their overall performance. However research that has investigated the effect on acute Cr supplementation on different variables of soccer performance and predominately sprint performance utilising a soccer simulation protocol is limited (Ostojic, 2004; Mujika et al 2000; Cox et al 2002). The Aforementioned studies have primarily focused on the effects of Cr supplementation on highly trained athletes that are competing at a high standard of competition. However no previous research has looked into the effects of acute Cr supplementation on amateur soccer players. Being as though Cr monohydrate is an immensely popular ergogenic aid not only among professional athletes but also amateur and recreational athletes, the benefit to amateur athletes needs to recognised. Previous research that has looked into the effects of acute Cr supplementation on soccer players using a soccer simulation protocol is discussed below. Ostojic (2004) examined the effects of acute Cr supplementation (3 x 10g doses for 7 days) on 20 young male soccer players (16.6 Â ± 1.9 years). For the testing procedure a double blind method was used and where subjects were either administered either Cr or placebo. Subjects completed two separate trials prior and post to Cr or placebo. The testing procedure consisted of a number of soccer specific skill tests which included a dribble test, sprint-power test, endurance test and a vertical jump test. Results found that there was a significant improvement in a number of the soccer specific tests; this includes superior improvements in sprint times, vertical jump scores and the dribble test. However no significant improvements were made on endurance performance after the two trials. Although a significant improvement was found in vertical jump performance, it is of concern to future researchers to whether the vertical jump test that was utilised during the design is a soccer specific test. During the test subjects were instructed to keep their trunk as straight as possible whilst keeping their hands on their hips to avoid contribution from the arms which doesnt successfully replicate jumping movements in soccer therefore questioning the validity of the vertical jump test as to whether or not it is a measure of soccer specific performance. The age of the subjects in this research can also be scrutinised. Eichner, King, Myhal, Prentice and Ziegenfuss (1999) confirmed that there was insufficient research to determine the acute and chronic side effects of Cr consumption in athletes under the age of 18 therefore places the subjects which were used in the mentioned study under possible risk. Eichner et al (1999) also highlighted that Cr supplementation in young athletes could have a possible degradation of ethics, by where a win at all costs mentality is fostered and an attitude by where ergogenic aids are necessary to win, which is the wrong message to be installing in young athletes. Likewise Mujika, Padilla, Ibanez, Izquerido and Gorostiaga (2000) concluded acute Cr supplementation (20g a day x 6 days) significantly improved sprint performance and found no significant improvement in endurance performance using a soccer simulation protocol. Mujika et al (2000) also documented no increase in vertical jump performance using a similar protocol to Ostojic (2004) which has minimal significance in a soccer simulation study. Mujika et al (2000) tested 19 elite male soccer players who at the time of investigation were highly trained, however only 17 fully completed the testing due to illness or injury. The protocol for this investigation consisted of a circuit of different exercises which consisted of a repeated sprint test (5 and 15m), vertical jump test and an intermittent endurance test. Findings in this study concluded that mean sprint times improved significantly (p This de-training effect is evident for the vertical jump test as no significant improvement between the two trials was found. However if there was a significant de training effect it would have had negative consequences on other testing variables such as sprint performance, this however is not the case as sprint performance significantly improved. Mujika et al (2000) should have took into consideration a possible detraining effect when devising the experimental design as this could have negatively affect the validity of the results. Cox, Mujika, Tumilty and Burke (2002) devised a study which tested Cr supplementation (20g a day) or placebo (20g glucose a day) on 14 elite female soccer players from the Australian institute of sport (AIS) using a soccer simulated protocol. The experimental design consisted of two trials before and after Cr or placebo over a 6 day period. The protocol consisted of fifty five 20m sprints, ten agility runs and a precision ball kicking drill which are separated by recovery walks, jogs and runs. The main findings in this study were that the average 20m sprint time in the Cr group decreased from 3.75 Â ± 0.19 to 3.69 Â ± 0.18s however this decrease in sprint time failed to reach the statistical significance level (p Cox et al (2002) also incorporated a standardised training regime and a controlled diet for the intervention week and also scheduled testing so that it would occur at the same time of day before and after supplementation. In contrast Mujika et al (2000) failed to utilise effective standardised procedures during their experimental design. As previously mentioned Mujika et al (2000) testing procedures took place 3 days after the subjects season had finished therefore training was not standardised due to the fact that subjects had no organised training sessions during the intervention week. Mujika et al (2000) also lacked a familiarisation trial, subjects were only familiarised with the testing procedures prior to arriving for the 1st trial which could substantially affect the results. However although Cox et al (2000) standardised procedures by included a controlled diet for the subjects, it is interesting to note that one of the subjects was a vegetarian, whos Cr content is virtually zero (Greenhaff, 1997). Research has found that vegetarians respond quicker and more effectively to Cr supplementation than those who follow a normal sedentary diet and have natural muscle creatine content (Burke, Chilibeck, Parise, Candow, Mahoney Tamopolsky., 2003; Watt, Garnham Snow, 2004) therefore scrutinising the validity of the results. It may be of future reference to eradicate vegetarians in a experimental design which utilises Cr supplementation due to the diet implications that vegetarians have. Soccer Simulation performance tests To date there has been a number of soccer simulation performance tests which have been utilised to assess and measure different physiological aspects of the game (Bangsbo and Lindquist, 1992; Cox, 2002; Drust, Reilly and Cable, 2000; Nicholas, Nuttall and Williams, 2000). These protocols have been implemented so that they take into consideration different aspects of soccer performance and try to replicate the exercise patterns that are observed during match play, however due to the spontaneity of the soccer it is difficult to assess every physical or metabolic demand (Drust, Reilly and Cable, 2000). Researchers have used different protocols when investigating the metabolic and physical demands of soccer, these can documented into laboratory based protocols (Drust, Reilly and Cable, 2000; Thatcher and Batterham, 2004) and field based protocols (Bangsbo and Lindquist, 1992; Cox, 2002; Nicholas et al 2000). Laboratory based soccer performance protocols Drust, Reilly and Cable (2000) devised a laboratory based protocol on a motorised treadmill what represented the work rates that are observed during soccer match play. For the experimental design 7 male university soccer players (24 Â ± 2 years) were used and the testing consisted of three separate testing blocks which were separated by 6 days. The protocol consisted of the different exercise intensities that are utilised during soccer match play; this consisted of walking, jogging, cruising and sprinting. The speeds at which these exercises were performed on the treadmill were consistent with speeds observed by Van Gool, Van Gervan and Boutmans (1988) during a match analysis. Each testing block consisted of two 22.5 minute cycles which consisted of 23 bouts which were followed by a recovery period of 71 seconds. During each bout the duration of each activity was as follows: walking 35 seconds (s), jogging 50.3s, cruising 51.4s and sprinting 10.5s. However in relevance to this research project it should be noted that the duration covered during the sprint bouts of the protocol of Drust, Reilly and Cable (2000) which is 10.5s does not successfully coincide with match analysis from several soccer studies that have documented the duration of sprint bouts during soccer match play. Research has found that the average sprint time during soccer match play lasts between on average two to four seconds in duration (Bangsbo, Norregard Thorso,1991; Mayhew and Wenger, 1985) therefore concluding in some instances Drust, Reilly and Cables (2000) laboratory based soccer specific protocol can be deemed as in valid as it fails to accurately replicate different soccer performance variables that take place in match play. Another lab based test that was utilised to measure specific variables in soccer performance was devised by Thatcher and Batterham (2004). For this protocol six male professional soccer players were used and the testing consisted of 29 minute exercise bouts on a non motorised treadmill that focused on replicating different speeds, durations, distances and heart rates that occur during soccer match play. Findings from this study suggest that the protocol that was utilised induced a similar physiological load to soccer match play and can be determined as a valid measure of soccer performance. Although lab based soccer specific protocols have been found to replicate some instances of soccer performance it is of consideration of this research project that the limitations and positives of such protocols be noted. The aforementioned lab based failed to perform a re-test procedure to conclude whether their protocols maintained reliability therefore the amount of error in each protocol cannot be determined. Another limitation of lab based testing is that due to tests being performed on treadmills, this limits the subjects to straight-line running only, therefore does not take into consideration lateral movements and agility patterns, which have found to be major characteristics of soccer performance (Bangsbo and Lindquist, 1992). These unorthodox movement patterns need to be taken into consideration when assessing soccer performance as they increase energy expenditure significantly (Nicholas et al., 2000). One positive aspect of lab based protocols are that procedures such as a ir temperature, equipment utilised and humidity can be easily standardised to remain constant throughout performance testing. Field Tests Nicholas et al (2000) devised the Loughborough Intermittent Shuttle test (LIST) to simulate the activity patterns during a game of soccer. The LIST consisted of two separate stages which were known as part A and part B. Part A lasted 70 minutes and consisted of five 15 minute exercise pe
