How does the academic study of problem solving and thinking relate to Essay
How does the academic study of problem solving and thinking relate to everyday life - Essay Example Along with maturation, people obtain substantial competence that enables them to solve common problems encountered daily. (Holyoak 1995, p. 267) However, Anderson (1993, p. 39) explains, not everything requiring solution, like routine activities, is indeed problems. For example, summing-up a three-month electric bill, though requires solution is not a problem because one simply has to compute it either manually or electronically, but how to pay the bill with practically nothing left in oneââ¬â¢s pocket is surely a problem. The difference here lies on the immediate availability of achieving the task. Computing the bill could be easily achieved with the simple knowledge of addition or much easier the use of calculator, but where to find the money to pay the bill not to be cut off power presents a problem, as there is no immediate solution to it. Hence a problem is determined by the gap between the present state and the target goal wherein the means to solve the gap is not immediatel y evident (Schwarz & Skurnik 2003, p. 267). Problem solving begins with problem identification (Rudd 2005, p. 11). Generally defined as the activity by which the goal of eliminating the gap is undertaken without certainty of success (Tallman, Leik, Gray, & Stafford, 1993, cited in Nelson, Brice & Gunby 2010, p.74), problem solving which could be correct or erroneous differs for every individual, because individual experiences and task demands, which problem solving entails, vary (Martinez 1998, p. 605). Similarly, the difficulty of solving problems differs in degree depending on the nature of the problem. Some could be easy; others could be truly hard or could never be solved at all. (Joswiak 2004, p. 19) ââ¬ËThe relative ease of solving a problem will depend on how successful the solver has been in representing crucial elements of the task environment in his problem spaceââ¬â¢ (Simon, 1978, p. 276). The more exposed a person to varied task of compelling nature, the greater is the chance of that person to handle problems of similar/related nature. For example, an ex-marine has the greater chance of surviving a physical assault than a language teacher who has yet to experience physical violence. Moreover, problem solving has two aspects: The answer that which solve the problem, and the solution procedure by which way the answer is known (Robertson 2001, p. 6). With a variety of problems that people come across everyday solutions also vary by which Robertson (2001, pp. 6-11) says problems can also be categorised. One, what knowledge does the problem require ââ¬â would it be ââ¬Å"knowledge-leanâ⬠or ââ¬Å"knowledge-richâ⬠problems (p. 7)? For example, household maintenance though complex requires simple management, whereas ensuring national security is far more complicated that it requires expertise. Steif, Lobue, Kara, & Fay (2010, p. 135) suggest that the ability to determine fitted conceptual knowledge in order to solve a problem is cons idered a metacognitive skill. This according to Greeno (1978, p. 62) is learnable. Although, Gagne (1979) clarifies that what can be learned in problem solving are its specific aspects, cited as: "rules of syntax and mathematics," "knowledge about particular objects and events," "specific cognitive strategies" (cited in Mayer 1987, p. 111). Two, what is the nature of the goal? Is it technical, routine, domestic, political,

Critical Evaluation Of Value Chain Analysis Marketing Essay
Critical Evaluation Of Value Chain Analysis Marketing Essay In todays world, due to the development of globalization and the improvement of science and technology, the international economic situation is fast-changing. Whats more, competition is severer than before. It is unadvisable for managers to make a long-term plan and then ask the whole company to implement it days and nights. Managers should analyze the internal environments and external environments continuously surrounding their own company and then make plans in accordance with the analysis. There are lots of approaches which can be used during the strategic analysis process, such as SWOT analysis, PESTIN analysis, Value Chain analysis and Porter Five Forces. Therefore, it is very essential for managers to understand the usages of them during the strategic analysis process. Moreover, the functions of these approaches are also deserved to be researched. The main purpose of this dissertation is to evaluate critically two approaches, value chain analysis and porter five forces, during the strategic analysis process in order to make managers acquaintance with the knowledge about these two approaches and then make better plans for their own companies. There are four parts in this dissertation begun with an introduction. In the second and third parts, this dissertation will provide critical evaluation of value chain analysis and porter five forces separately by some empirical examples to illustrate the disadvantages and advantages of value chain analysis and porter five forces. A conclusion will be made in the end. Critical Evaluation of Value Chain Analysis Used during the Strategic Analysis Process According to Robbins (2009), only depending on value chain analysis, an organization delivers its products or services to its customers fast and quickly. This part will introduce what the value chain analysis is and the general review about value chain analysis. Simultaneously, this part will also explain the disadvantages and advantages of Value Chain Analysis by empirical examples. 2.1 What is Value Chain Analysis? Value chain analysis was proposed in 1985 by Michelle Porter in his book Competitive Advantage: Creating and Sustaining Superior Performance (Robinson, 2009) to describe the way of how customer value accumulates along a chain of activities leading to an end product or service (Institute of Management Accountants, 1996). Porter described that value chain analysis was the internal processes or activities performed by a company to design, produce, market, deliver and support its products (Robinson, 2009, pp564). Porter also claimed that the main purpose of value chain analysis is to create a value chain strategy to meet and surpass customers demands and desires (Scholes and Whittington, 2010). And according to Robinson (2009), a successful value chain management should meet the following factors, including collaboration and cooperation, technical investment, organization process, leadership, employees, organizational culture and attitudes. Porter describes two major categories of busine ss activities: primary activities and support activities (Institute of Management Accountants, 1996, pp1). In 1993, Shank and Govindarajan broadened the definition of value chain analysis and states that the value chain is the value-creating activities of any firm to provide products and services to final consumers hands. 2.2 The General review about Value Chain Analysis The importance of value chain analysis propels lots of scholars to spend more time and energies to do researches on value chain analysis. In 2006, Khan, Pochampalli, Ding and Ponce adopted lots of approaches to make strategic case analysis, including value chain analysis taking the analysis of Nucor Corporation as the example. They analyzed Nucor Corporations mission, products and services, leadership, culture, structure and governance and gained the concluded that Nucor Corporation had the unique leadership, strong corporate culture and decentralized structure, which led this company to be successful and have effective corporate governance (Khan, Pochampalli, Ding and Ponce, 2006). In 2003, Dekker wrote an article named Value Chain Analysis in Interfirm Relationships: A Field Study to analyze the influence of value chain analysis on management accounting. In this article, Dekker pointed out that interfirm relationships was the new challenges for management accounting and a value cha in analysis is a useful tool to meet this challenges. Moreover, Awa and other scholars also proposed a research called collaborative experience of value chain architecture: a systemic paradigm to building customer loyalty in 2011. There are still another researches on value chain analysis, due to the limited space, this dissertation will not list them one by one. 2.3 Explain the Disadvantages and Advantages of Value Chain Analysis by Empirical Examples According to Robinson (2009), value chain analysis has a lot of advantages and disadvantages. In this part, this dissertation will explain the disadvantages and advantages of Value Chain Analysis by empirical examples. 2.3.1 The advantages of Value Chain Analysis by Empirical Examples Before listing the advantages of value chain analysis, this dissertation first show a survey result about the benefits of value chain analysis made by Taninecz (2000) (p44). From this survey result, it is reasonable to gain the conclusion that a successful value chain analysis can improve the services level to the customers. If the company performs well on each point of the value chain and the employees cooperate well and try their best to optimize service process, the service level to the customers can be improved (Scholes and Whittington, 2010). Meanwhile, a successful value chain analysis can help company increase sales, save cost, increase market, reduce inventory and improve logistics management (Robinson, 2009). Therefore, value chain analysis emphasizes not only the production process but also the various activities that make up the chain (McCormick and Onjala, 2007). Tetra-Pak, a multinational food packaging and processing company of Swedish, is one of the excellent examples which reconfigured the value chain in the packaging industry (Institute of Management Accountants, 1996). Tetra-Pak designs and uses a filling machine to package step by step, which brings a great change to the packaging industry (Institute of Management Accountants, 1996). Under this circumstance, no space in filling and packing would be wasted. According to the survey made by institute of management accountants (1996), the famous furniture Sweden Company IKEA also reconfigures the value chain and IKEA Company divides its operation activities into several parts, including design, assembly and even home delivery and has specific requirements in each activity, which also brings a revolution to the furniture industry in Swedish and even worldwide. Nucor Corporation is one of the largest steel manufacturers in the United States and takes value chain analysis during the strategic analysis process (Ding, Khan, Pochampalli and Ponce, 2006). According to them (2006), the value chain of Nucor Corporation includes firm infrastructure, human resource, technology development, procurement, logistics and other activities and due to the usage of value chain analysis help Nucor Corporation establish strong organization culture and unique leadership, which provide an excellent foundation for this company. All in all, value chain analysis during the strategic analysis process can help managers to divide operation activities into several different activities and assign tasks to specific employees and then through the cooperation and collaboration between employees, company can be a success. 2.3.2 The Disadvantages of Value Chain Analysis by Empirical Examples In the section 2.3.2, this dissertation has introduced the advantages of value chain analysis. However, managers should overcome some obstacles when they adopt value chain analysis during the strategic analysis process. In other words, there are some deficiencies of value chain analysis. For example, if the employees are unwilling to change their status and to share information between each other, they can not collaborate and cooperate with each other. Under this circumstance, the value chain analysis can not be implemented fully and effectively (McCormick and Onjala, 2007). Secondly, excessive trust between employees also can lead value chain analysis to become a failure (Scholes and Whittington, 2010). The implementing of value chain analysis needs employees and managers have necessary abilities, such as the abilities of good coordination and team spirits and the abilities to train all the employees. However, it is difficult for managers and employees to make themselves acquaintanc e with these abilities. For example, American Standard Company, Deere Company and Furon Company have come across lots of big difficulties. Due to the development of information technology and knowledge economy, the global economic situation is fast-changing. The managers have to change the value chain of the operation activities according to the change of environment. Therefore, if the company wants to make a long-term plan, the value chain will lose its efficiency, otherwise the company will spend lots of costs to change the value chain and organize employees to implement the value chain (Cadle, Paul and Turner, 2010). Pentagon Company, a famous high technology company in the United States, has no chance to take value chain analysis during the strategic analysis process if this company can not ensure the security of its own website (Robinson, 2009). Therefore, there are still some disadvantages of value chain analysis. 3. Critical Evaluation of Porters Five Forces Used during the Strategic Analysis Process Same as the value chain analysis, Porters Five Forces also has advantages and disadvantages, which will be exposed in this part by some empirical examples. 3.1 What is Porters Five Forces? Porters Five Forces Analysis is a theory made by Michael Porter, who is a professor in Harvard University. He came up with five factors that may influence the profitability of a company, namely the intensity of rivalry among existing competitors, threat of entry by new competitors, pressure from substitute products, bargaining power of buyers, and bargaining power of suppliers (Scholes and Whittington, 2010). First, the rivalry can be weak or intensive. If it is weak, theres no need to worry about it. But if it is intensive, it should be pay much more attention to. When having the intensive rivalry among existing competitors, one is likely to be in a cut-throat position. Many factors will influence the intensity of rivalry, including the size of competitors, the costs of products, and the product differentiation (Scholes and Whittington, 2010). Second, the new companies are the other threats to ones benefits. They will become the obstacles to expend your market scale and cut off your market share (Robinson, 2009). Third, pressure from substitute products is another barrier for a company to get interests. Fourth, bargaining power of buyers is of the vital importance in the effect of the benefits (Scholes and Whittington, 2010). Since the profit margin has close relationship with the price. When the price is low, the profit margin may be high and vise versa. Last but not the least, bargaini ng power of suppliers is much similar to the factor of bargaining power of buyers. When the supply price is low, the costs of the product are low. Therefore, the profit margin will be high due to the low cost. 3.2 The General Review about Porters Five Forces As mentioned before, Porters Five Forces Analysis has its own characteristics. These are helpful when used as managerial strategies in big decision of the company. Most of the researches about the Porters Five Forces Analysis is based on the prior experiments, collective data and analysis. For example, the application of the Porter Five Forces Analysis in Internet (Nikolopoulos, 2005à ¼Ã¢â¬ °and automobile industry (Cafferky, 2005) . All these researches can be viewed as the practical theories for future use. Undoubtedly, the aim of these studies is to find out the managerial problems and ways to solve these problems. This model is strive to improve the companys performance through the analysis, namely which part of its market it the most profitable one and which is the most cost-consuming one. After the Porters Five Forces Analysis, great efforts should be made to maximize the former market and minimize the latter market. It will help the company make the greatest profits as well. The well management of the five most important factors influencing the market share will reduce the difficulties standing in the progressing path. This framework of the Porters Five Forces can also define the opportunities, threats, strengths and weaknesses. Ones structure coping with these five forces can determine competitiveness of the company. 3.3 Explain the Disadvantages and Advantages of Porters Five Forces by Empirical Examples The Porters Five Forces Analysis has its advantages and disadvantages. If used well, it will help make great profits for a company. As for the advantages, it is very simple and direct. It has a simple framework in dealing with managerial problems. However, it also has shortcomings. For examples, it is not as clear as the Value Chain Analysis. The five factors cannot be separated clearly when analyzing. On the other hand, it can be easily affected by other factors, such as the size of the company, different economic environment and national investments. 3.3.1 Advantages of Porters Five Forces There are many advantages of Porters Five Forces Analysis, but two are among the most important ones. The first one is simplicity. Compared to other models, it is very simple. Five factors are easy to define. In the Mobile Company, the Porters theory provides an easy access to the information about these areas. It is known to all, this area is much more complicated regarding the practical market. But the five factors narrow these complicated factors down to the relationship among the suppliers, the sellers, and the buyers. The cash flows among the three most important participators. The main rivalries in this field in China are China Mobile, China Unicom and China Telecom. The competition is still very fierce (Wu, 2012). As the emerging of the iphones and various kinds of smart phones, China Unicom Company begins to take on the stage by its excellent 3G service. The company can quickly identify its valuable market and worthless market by the Porters theory. Here the word valuable mea ns that it will make profits for the company and worthless means that it makes little contribution to the companys benefits. Although there isnt the fourth competitor, the potential threats still exist. However, from Porters theory, the problems can be simply defined and solutions can be easily made to solve the problems. The second one is directness. The diagram of the Porters Five Forces Analysis seems very direct to analyze. In automobile industry, substitute products are used in order to improve the performance and to increase profits. It goes straight to the point so that the weakness and threats. For example, the General Motors Corp decides to reduce the carbon emission of its cars. So it tries its best to cooperate with an Italy company who can produce the environmental-friendly combustion motor. With the new motors, the company successfully increases its competitiveness and decreases its costs. Innovation ranks the most important factor affecting ones profitability. Without innovation, one could not move forward. But if substitute products are used instead of innovation, it may be a solution at the moment. And in modern society, such action can express its good images of being responsible. It means the company is not a profit-striving business man. It cares about people, society and the whole world. 3.3.2 Disadvantages of Porters Five Forces The first one is that it is unclear. The five forces may be easy to define, but it has no clear boundary. Each involves many details. What is more important, they cannot be separated clearly. In other words, they overlap each other. For instance, in the steel industry, the supplier power changes with the buyer power, and the buyer power is also swifts with the supplier power. They are mutually influenced. It is difficult to say which one is the fatal factor. Also in the General Motors Corp, five factors should be analyzed together. None of them can be separated from others. For example, the threats of the new entry warn the General Motors Corp to change its traditional producing forms. New technology should be employed to enhance its images and competitiveness. Therefore, the company analyses all of the five factors to solve the problems and to expand its market share all over the world. Second, it is easy to be influenced by other uncontrollable factors. Also in the steel industry, it has gone through many stages, from immature to mature (Ponce, 2006). When at the immature stage of lifecycle, the suppliers and the buyers are instable, while in the mature stage, they are consolidate. Different states of the buyer power and the supplier power will lead to different problems. It is too hush to make decision only according the only five factors. An overview should be made to identify the whole situation. And a comprehensive thinking should be put into the analysis. Although there are shortcomings of the Porters Five Forces Analysis, it is still a valuable framework used to discriminate the strength, weakness, threats and opportunities of the company. And it is useful to solve various problems that one could meet. Conclusion In conclusion, managers should make plans for their own companies according the fast-changing economic situation worldwide and during the strategic analysis process, it is essential for them to adopt some useful approaches, such as value chain analysis, SWOT analysis, porter five forces analysis and the like. Therefore, this dissertation provides a critical evaluation of value chain analysis and porter five force during the strategic analysis process. Before representing the advantages and disadvantages of value chain analysis and porter five forces, this dissertation has provide the definition and general literature review about these two approaches. From the above analysis, it is reasonable to conclude that the value chain analysis and porter five forces have advantages as well as disadvantages, which can help managers to learn about the general knowledge about these two approaches. Meanwhile, during the strategic analysis process, the managers can make full use of their advantages to gain more efficiency. Due to the limited energy and time, limitations must exist in any kind of research. This dissertation mainly takes the secondary data, which mainly are from journals, books and website, so it is difficult to ensure that the data are reliable enough. Due to the limited space, this dissertation can not explain all the disadvantages and advantages of these approaches and the listed examples may not represent all the industries and be typical. And all of these are the key points which are needed to be improved in the future. In the end, this dissertation will give the audiences some suggestions for future research to do the researches about the merits and demerits of these approaches better in the future. For example, the researchers should do some practical surveys about these two approaches to learn about the usage situations in different industries. Secondly, the researches also can make good use of books, journals, websites and even magazines to gain more and better information to give more specific analysis about the disadvantages and advantages about these two approaches.

Examples of human societies that collapsed prior to c. 1700 CE
Classic Mayan civilization was among the most advanced to ever develop in the New World prior to European contact, and at its height, Mayan cities supported populations estimated at 250 to 750 people per square mile. 1 They were the only advanced Mesoamerican civilization to have developed an extensive system of writing; they also developed their own unique calendar, and extensively studied mathematics and astronomy.The Classic period of Maya civilization is thought to have begun around 250 CE, based on scholarly interpretation of glyphs on Mayan monuments. 2 It is thought that the occurrence of certain repetitive glyphs within an area signify the rise of a local dynasty or kingdom. Based on the number of archeologically verified houses, the Mayan population is estimated to have exponentially increased to its peak of approximately 13 million in around 750CE3, accompanied by a similar increase in the number and size of monuments and buildings.After this point these numbers decline unt il around 900 CE, which is said to mark the collapse of the Classic Mayan civilization in general. Among Mayan cities of the Classic period, however, some were noted to have peaked and collapsed as early as 600 CE, while others persisted much longer, such as Chichen Itza (around 1250 CE). 4The end of the Classic Maya period was not the end of Mayan civilization itself, because Spanish explorers such as Cortes encountered Mayan resistance as they established their presence in the area. While diseases introduced by the Spanish occupation eventually brought the survivorsââ¬â¢ numbers down to an estimated 3,000 in 1714 CE5, the Spanish occupation itself was not a significant factor in the decline of a civilization which had already reached its zenith and collapsed centuries before.Although the Spaniardsââ¬â¢ religious fervor drove them to destroy several of the Mayan manuscripts out of fear of paganism, the surviving written records have enabled archeologists to understand much ab out the Mayan writing system, and the explorersââ¬â¢ own documentation of the Maya have proved helpful to scholars6. Modern scientific methods have enabled us to understand a great deal about the factors that may have undermined such an advanced society and brought about its downfall.Located at latitudes of 17o to 22o north of the equator, rainfall in the land of the ancient Maya is seasonal and unpredictable, and hence in reality, the habitat of the Mayan civilization can be most accurately described as a seasonal rainforest or desert7. Rainfall varies with location, from 500 mm a year along the north coast, to 4,000 mm a year in some southern areas8. Due to the unpredictable timing and amount of rain in any given season, even modern farmers have frequently encountered difficulties in growing crops.The Maya obviously succeeded in their agricultural efforts for a long time, and cities such as Tikal even show evidence of the construction of cisterns and reservoirs to store water i n times of drought9. However, considering the high population density of Classic Mayan cities at their peak, even with their successful agriculture and ability to store water reserves in times of drought, the Maya would still have been vulnerable to severe, prolonged drought ââ¬â perhaps enough to send them into collapse.To find records of what the climate in the Mayan homeland was like at that time, geologists from the University of Florida gathered sediment cores from several lakes in the Yucatan area and analyzed the patterns of deposition, which indicate that the driest interval in the region in the past 7,000 years had coincided with the collapse of the Classic Maya civilization, between 800-1000 CE. A further study by Larry Peterson and Gerald Haug used x-ray fluorescence to analyze oceanic sediment cores.Titanium and iron deposits in the sediment were used as indicators of rainfall, because these elements originate predominantly from continental rocks and thus a high amou nt of titanium and iron deposits would reflect on a high volume of rainfall on land in that year. The results corroborated the previous study that had been made using freshwater sediments, indicating an unusually long and severe drought during the period of Classic Maya collapse10. Despite this evidence, the drought theory behind the collapse of Classic Mayan civilization remains far from providing a complete and thoroughly satisfactory explanation.It fails to account for the previously mentioned differences in the dates of collapse of cities that lay within the same region and presumably suffered from the same drought. It has been suggested that the first cities to fall to the drought were more vulnerable by virtue of location, being less proximate to natural bodies of water, such as springs and rivers. This could then lead to warfare between cities due to competition for scant resources, and since the Mayan cities never were united into a single empire, it is likely that such warf are may have greatly destabilized Mayan society.As with other cases of collapsed societies throughout history, it is likely that multiple causes, of which drought was the most significant but by no means the only one, contrived to bring about the fall of the advanced Mayan society. Another society that was founded, peaked, and collapsed close to our modern day home would be the Anasazi of Chaco Canyon. This society had collapsed well before the arrival of Columbus, but unlike the Maya, left behind no written records. What is known about the Anasazi comes from using a combination of scientific methods to analyze what remains of their society.The Native Americans who first settled the U. S. Southwest faced a problem that is still obvious today. This region has very low and unpredictable rainfall. Drought is often cited as the obvious major reason for Anasazi societyââ¬â¢s collapse, but recent studies indicate that the Anasazi sites themselves may still have been able to sustain a p opulation at the time of their abandonment. 11 In the study of the decline and collapse of Anasazi society, archeologists have relied heavily on a few methods of analysis.One lies in the field of dendrochronology and is particularly useful since the Anasazi, particularly at Chaco Canyon, made heavy use of timber for their construction. Using the thickness of individual tree rings from a particular piece of timber, dendrochronologists are able match patterns in the rings of different trees from the same region. By comparing several different trees in this manner, dendrochronologists are able to correctly associate each ring with a specific year, starting from trees in the present day and dating back for thousands of years.Dendrochronological studies thus present highly detailed information regarding the weather patterns of the U. S. Southwest and can indicate not only years of high rainfall or drought, but also the amount of rainfall and the season within a particular year during whi ch the rain fell12. Scientists have also analyzed the contents of pack rat middens to gain insight into the local vegetation. Pack rats (Neotoma spp. ) are rodents that have lived in the area for thousands of years, and gather vegetation and other organic material from within their small territorial range, preserving it in their nests, called ââ¬Ëmiddensââ¬â¢.Pack rat midden analysis has allowed scientists to determine that the initial area around Chaco Canyon was forested with pinyon and juniper trees which no longer grow today in the vicinity, and led to the conclusion that the Anasazi of Chaco Canyon had deforested their surrounding woodland for firewood to fuel their pottery making, and for construction material as Chaco became an effective political and religious center for the Anasazi society. 3 Furthermore, studies of strontium isotopes in other types of wood used at Chaco indicate that several conifer logs had actually been imported from more distant areas such as the Chuska and San Mateo mountains, presumably after Chaco itself had been deforested. 14 It is believed that this deforestation led to irreversible nutrient loss in the soil of the Chaco area, which is further strengthened by studies of food remains at archeological sites.These remains indicate that as the food supply in Chaco deteriorated, its inhabitants resorted to eating rabbits and mice, and eventually cannibalism, as evidenced by boiled human bones with smooth ends and human muscle protein found in preserved dried human feces. 15 It is probable that cannibalism came with social unrest, possibly a revolt by the providers of Chaco Canyon against the elite, and that together with these factors, a drought (dated by tree rings to around 1130 CE) pushed Anasazi society at Chaco past its limits.Numbering at possibly 5,000 or more at their peak, the Chaco Anasazi had already exhausted and deforested their environment, and likely fought amongst themselves for the remaining resources. The final example I choose to discuss is the collapse of the Norse settlement of Greenland. Greenland is a harsh and fragile environment, but at the time of the Norse occupation around 980 CE, it was experiencing a relatively warm period that lasted from 800 ââ¬â 1300 CE, ending with the start of the Little Ice Age.Information about Greenlandââ¬â¢s climate is derived from palynological studies, wherein scientists analyze pollen found in mud deposits extracted from the bottom of lakes and bogs, and ice core studies. Pollen studies reveal what sort of plants were growing in the area, and can reveal subtle shifts in climate when pollen from cold-tolerant species is prevalent.Similar to dendrochronology, ice core studies reveal the amount of snowfall within a year, and by using a mass spectrometer it is possible to analyze the content of oxygen isotopes within a layer of snow, with the ratios of these isotopes indicating the average climate during that year. Ice cores can also reveal how stormy the year was in which the snow fell by analyzing concentrations of sodium and calcium ions, which are brought inland by sea spray. 16 By 1000 CE the Norse had settled Greenland in two different areas with a total population of around 5,000.They relied on hay farming to feed their livestock, which consisted of goats, sheep, and cows, but due to the length and severity of their winters, they were forced to estimate how many animals they could support with their stockpiled hay, and slaughter the remainder. If the winter lasted longer than expected, the consequences could obviously lead to the starvation and death of the few remaining livestock. Their pastoral lifestyle, use of turf for buildings, and need for firewood demanded the clearing of native vegetation, and livestock trampling hampered the regeneration of trees.Palynological studies support the conclusion that the Norse had deforested the environment and caused soil erosion, with the decline of pollen from willow an d birch trees as well as the presence of topsoil at the bottom of lakes indicating the loss of plant cover and soil. The loss of abundant lumber resulted in the halting of construction involving wood, and the lack of firewood limited the Norse in their efforts to pasteurize dairy products and extract iron for their implements.Unlike the Norse, the Inuit who settled Greenland in about 1200 CE managed to exploit the resources of the sea with their kayaks, hunting plentiful fish (which the Norse oddly refused to eat, as evidenced by the complete lack of fish remains in garbage) and whales, whose blubber could be used for fuel and warmth. Possible hostile contact between the Norse and Inuit may also have led to the decline of Norse society on Greenland, because it prevented the Norse from peacefully interacting with their neighbors and learning from them how to adapt to the extreme conditions.Another factor that weakened the Norse settlement was the increasing difficulty of transportati on, and hence trade and communication, across the sea with mainland Norway, as the cold weather brought by the Little Ice Age set in and ice began to make seafaring dangerous. 17 Summarized concisely in the words of Jared Diamond, the Norse settlement of Greenland collapsed due to ââ¬Å"environmental damage, climate change, loss of friendly contacts with Norway, rise of hostile contacts with the Inuit, and the political, economic, social, and cultural setting of the Greenland Norse. â⬠18

Formal Essay in Human Relationships and Life Transitions Being an Adult Essay
Throughout this essay, I will be discussing the transition of adolescence. This transition is a stage of development between childhood and adulthood, from about 12 to 20 years of age. This transition from childhood to adulthood is smooth for some but rough for others(Caspi, 2000). This essay will discuss predictable and non-predictable elements of the transition. Health in adolescence issues this involves drugs & alcohol abuse and sexually transmitted infections (STIs) are classified as unpredictable elements. Physical Development (body growth and physical changes during adolescence) or Puberty and Cognitive Development are classified as a predictable element during the transition. It will also explore the impact on relationships and concepts of self for persons undertaking the transition. Furthermore, it will deliberate the contributions of contemporary and seminal authors to describe the differences between the two past and presents authors/researcherââ¬â¢s theories in understanding of the adolescence life transitions. Another factor that will be discussed is the concept of self during the transition, and then finally it will comprehensively explain the importance for nurses to understand the adolescence transition. A.The importance of predictable and unpredictable elements in Adolescence transitions will assist in identifying the significant changes in every life event transition. Moreover, it will also benefit in supporting adolescent to meet challenging changes throughout the transition. The first predictable element is puberty the biological transition of adolescence, the most noticeable sign of being an adolescent. Theoretically, puberty refers as a collective term to refer to all the physical changes that occur in the growing girl or boy as the individual passes from childhood into adulthood(Habermas & Bluck, 2000). In boys a major change is the increased production of testosterone, a male sex hormone, while girls experience increased production of the female hormone oestrogen(Dedovic, Wadiwalla, Engert, & Pruessner, 2009). In boys a major change is the increased production of testosterone, a male sex hormone, while girls experience increased production of the female hormone oestrogen (Carpentier & Fortenberry, 2010). Internally, through the development of main sexual characteristics, adolescents become capable of sexual reproduction. Externally, as secondary sexual characteristics appear, girls and boys begin to look like mature women and men. In boys primary and secondary sexual characteristics usually emerge in a predictable order, with the rapid growth of the testes and scrotum, accompanied by the appearance of pubic hair. In later years, it will begin the growth of facial and body hair, and a gradual lowering of the voice. Around mid-adolescence internal changes begin making a boy capable of producing and ejaculating sperm. In girls, sexual characteristics develop in a less regular sequence. Usually, the first sign of puberty is a slight elevation of the breasts, but sometimes this is preceded by the appearance of pubic hair. In teenage girls, internal sexual changes include maturation of the uterus, vagina, and other parts of the reproductive system. Menarche(Cochrane, 1993). Regular ovulation and the ability to carry a baby to full term usually follow menarche by several years. The second predictable element is Cognitive Development transition a second element of the passage through adolescence is a cognitive transition(Champion & Collins, 2010). Compared to children, adolescents think in ways that are more advanced, more efficient, and generally more complex. Adolescence individuals become better able than children to think about what is possible, instead of limiting their thought to what is real. Whereas childrenââ¬â¢s thinking is oriented to the here and nowââ¬âthat is, to things and events that they can observe directly, adolescents are able to consider what they observe against a backdrop of what is possibleââ¬âthey can think hypothetically. Second, during the passage into adolescence, individuals become better able to think about abstract ideas. This is clearly seen in the adolescentââ¬â¢s increased facility and interest in thinking about interpersonal relationships, politics, philosophy, religion, and moralityââ¬âtopics that involve such abstract concepts as friendship, faith, democracy, fairness, and honesty. Third, during adolescence individuals begins thinking more often about the process of thinking itself, or metacognition. As a result, adolescents may display increased introspection and self-consciousness. Although improvements in metacognitive abilities provide important intellectual advantages, one potentially negative by product of these advances is the tendency for adolescents to develop a sort of egocentrism, or intense preoccupation with the self. Acute adolescent egocentrism sometimes leads teenagers to believe that others are constantly watching and evaluating them, much as an audience glues its attention to an actor on a stage. Whereas children tend to think about things one aspect at a time, adolescents can see things through more complicated lenses. Adolescents describe themselves and others in more differentiated and complicated terms and find it easier to look at problems from multiple perspectives. The unpredictable elements are health related issues in adolescence are alcohol and other drug use. Experimentation with psychoactive substance is widespread during adolescence. Psychoactive substances are naturally occurring or artificial materials that act on the nervous system, altering perceptions, moods and behaviour. They range from naturally occurring substances, such as alcohol, which is produced from the fermentation of plant sugars by yeast, to designer drugs such as ecstasy. Most teenager experiment with different substances, constituting substance use and in some individualââ¬â¢s experimentation escalates into habitual or repeated usage known as substance abuse. They also engaged in ââ¬Å"binge drinkingâ⬠which arising in recent years. Binge drinking is defined as the consecutive ingestion of five or more standard drinks in less than two hours. Other factors of unpredictable health issues is sexually transmitted infections, adolescent sexual behaviour may impose a significant health risk to teenagers through a range of sexually transmitted infections (STIs). Sexually transmitted infections are bacterial and viral infections that enter the body via the mucous membranes of the mouth and the sex organs following physical contact. Sexually transmitted infection includes syphilis, gonorrhoea, genital lice, scabies, chlamydia, herpes, genital warts, hepatitis and HIV/AIDS. The reason for the high rates of STIs in adolescents is that this age group is more prone to sexual experimentation and risky sexual behaviours than other age groups. Risky sexual behaviour includes unprotected sexual activity without using barriers such as condoms, sexual activity involving multiple partners and sexual activity involving partners whose sexual is unknown. B. The impact on relationships and concepts of self for persons undertaking the transition is established by a personal identity a key task of adolescence is successful resolution of Eriksonââ¬â¢s psychosocial crisis of identity versus role confusion. Identify formation involves selectively integrating some aspects of earlier childhood identity and discarding others. Successful resolution of the identity crisis of adolescence depends on the opportunities to experiment with different social roles and activities. Individual differences identify achievement are due to culture, gender roles , peer influences, parenting styles and life circumstances experienced by adolescents, which may increase or decrease opportunities for exploration. Self-concept is based on more abstract beliefs and values than the concrete and comparative ideas of self during childhood. Increased of perspective-taking ability may reveal ââ¬Ëtrueââ¬â¢ and ââ¬Ëfalseââ¬â¢ selves in relation to interactions with different people, but this can reflect positive experimentation with different roles that contribute to self-concept. Self-esteem decreases significantly between child self-concept and mid- adolescence, and more dramatically for girls than for boy s. The sex differences is probably anchored to sex-role differences, greater body image dissatisfaction in girls than in boys, and the differential boost to self-worth that romantic relationships bring to adolescent boys and girls. Parent ââ¬âchild relationships become less asymmetrical term s of the balance of power during adolescence compared with childhood, as a result of adolescentââ¬â¢s push for autonomy. There are wide individual differences in the degree of autonomy achieved by adolescents, depending on parenting styles and cultural and gender based norms and attitude. During adolesce, close same-sex cliques and larger, looser amalgamations of several cliques called crow. Cliques and crowds provide the backdrop for new cross-sex interaction, including romantic relationships. Peer group conformity within cliques seeks out different kinds of advice and support from both parents and peers, Nonetheless, for minority ineffective parenting and influenced with a wrong crowd will experience a criminal career, exacerbate the pre-existing interpersonal difficulties that predispose adolescent to violence and being a gang members in the society. Bullying is also common in the society especially teens in primary and high school, it can affect the psychosocial development of a person. Positive peer relationships include same-sex friendships that are high in intimacy and mutual support are both essential in bridging to a successful romantic relationships which may also begin during adolescence. During adolescence, most individuals experience their first sexual intercourse. The age when this occurs is becoming earlier, depending on gender, cultural constraints and peer influences. Sexual minority status ââ¬âlesbians, gay or bisexual may pose additional challenges to identify formation and sexual maturation during adolescence. C.The contribution of past and present authors and researcherââ¬â¢s in understanding towards the adolescent life transitions has vast changes in time. According to Kohlbergââ¬â¢s theory (Benenson, Tennyson, & Wrangham, 2011) extended Piagetââ¬â¢s work on moral development during the 1960ââ¬â¢s uses male protagonist only as an examples of his theories which contradicts Carol Gilliganââ¬â¢s author of her popular book , ââ¬Å"In a Different Voice: Psychological Theory and Womenââ¬â¢s Developmentâ⬠(1982), suggested that Kohlbergââ¬â¢s theories were biased against women, as only males were used in his studies. By listening to womenââ¬â¢s experiences, Gilligan offered that a morality of care can serve in the place of the morality of justice and rights espoused by Kohlberg. In her view, the morality of caring and responsibility is premised in nonviolence, while the morality of justice and rights is based on equality. (Gilligan, 1982). CONCLUSION As we discussed the main points of being adolescence it embodies the importance, relevance and impact of a particular life event transition. Adolescence is a distinct stage that marks the transition between childhood and adulthood. Adolescents are capable of abstract reasoning. Although you may still include the family in education, adolescents themselves are a major focus of teaching since they have considerable independence and are, consequently, in more control of the degree to which recommendations will be carried out. Adolescents have many important developmental tasks to achieve. They are in the process of forming their own identity, separating themselves from parents, and adapting to rapidly changing bodies. Bodily changes at puberty may cause a strong interest in bodily functions and appearance. Sexual adjustment and a strong desire to express sexual urges become important. Adolescents may have difficulty imagining that they can become sick or injured. This may contribute to accidents due to risk taking or poor compliance in following medical recommendations. Because adolescents have a strong natural preoccupation with appearance and have a high need for peer support and acceptance, health recommendations that they view as interfering with their concept of themselves as independent beings may be less likely to be followed. Therefore, as sexual adjustment and strong sexual urges characterize this age, the nurse may do significant teaching about sex education and contraception. In addition to teaching adolescents about why and how their bodies are changing, the nurse is also in a good position to dispel misconceptions young patients may have about sexual development or sexual behaviour. Teaching adolescents about sexuality requires a special sensitivity and understanding. Respect for the patientââ¬â¢s modesty, privacy, and opinions are critical to establishing an atmosphere of openness and trust. In addition to sex education, other important patient teaching areas are alcohol and drug abuse and general health measures, such as the importance of good nutrition and exercise as the basis for life-long health. Regardless of the topic, health education for adolescents is more effective when the nurse establishes trust by respecting the adolescentââ¬â¢s needs, shows empathetic understanding, and answers questions honestly. Patient teaching for adolescents should take the form of guidance rather than lecturing. Nurses who gain credibility with an adolescent patient establish themselves as the teen-agerââ¬â¢s advocate rather than representatives of the parents. The nurse may increase health teaching effectiveness by including the family. The nurse can give guidance and support to family members that can help them understand and respect adolescent behaviour. Parents should be encouraged to set realistic limits for adolescents while still allowing them to become increasingly responsible for their own health care management.

Definition of a Prepositional Verb and How to Use One
Definition of a Prepositional Verb and How to Use One A prepositional verb is an idiomatic expression that combines a verb and a preposition to make a new verb with a distinct meaning. Some examples of prepositional verbs in English are care for, long for, apply for, approve of, add to, resort to, result in, count on,Ã and deal with. The preposition in a prepositional verb is generally followed by a noun or pronoun, and thus prepositional verbs are transitive. Examples and Observations God has cared for these trees, saved them from drought, disease, avalanches, and a thousand tempests and floods. But he cannot save them from fools. (John Muir, The American Forests. The Atlantic Monthly, 1897)The difference between the old ballplayer and the new ballplayer is the jersey. The old ballplayer cared about the name on the front. The new ballplayer cares about the name on the back. (Steve Garvey)I believe in equality for everyone, except reporters and photographers. (Mahatma Gandhi) Prepositional verbs consist of a transitive verb plus a preposition with which it is closely associated. He stared at the girl.She finally decided on the blue car. Prepositional verbs do not take the particle movement rule. The verb and the following preposition can be separated by an adverb, and the preposition can precede a relative pronoun and appear at the beginning of a wh- question. He stared intently at the girl.The girl at whom he was staring was strikingly beautiful.At whom was he staring? (Ron Cowan, The Teachers Grammar of English. Cambridge University Press, 2008) Pronouncing Prepositional Verbs A prepositional verb consists of a verb plus a particle which is clearly a preposition: for example, look at, send for, rely on. These are mostly lexically singly stressed, with a primary stress going on the verb. Thus look at has the same stress pattern as edit or borrow. The second element, the preposition, being unstressed, does not get accented (unless for contrastive focus). (John Christopher Wells, English Intonation. Cambridge University Press, 2006) The Difference Between Phrasal Verbs and Prepositional Verbs There are a number of syntactic criteria you can use for distinguishing phrasal verbs from prepositional verbs: in transitive phrasal verbs, the particle is movable, but the preposition in a prepositional verb is not;the NP is the object of the verb in phrasal verbs rather than of the preposition;in both transitive and intransitive phrasal verbs, the particle carries stress, as in She took the cap off or The plane took off, while prepositions are unstressed, as in We knocked on the door.adverbials cannot intervene between the verb and the particle whereas they can between the verb and the preposition, *looked quickly up the information, but looked quickly into the oven. (Laurel J. Brinton, The Structure of Modern English: A Linguistic Introduction. John Benjamins, 2000)
