PRODUCTIVITY GROWTH HYPTHESIS Essays - Statistical Inference

PRODUCTIVITY GROWTH HYPTHESIS Essays - Statistical Inference PRODUCTIVITY GROWTH HYPTHESIS Business PRODUCTIVITY GROWTH HYPTHESIS In this assignment, we will attempt to study the effects that difference in Income Ratio (henceforth known as I.R.) between the years 1980 and 1990 have on the Productivity Growth (P.G.) during the same period of time. The Income Ratio of one specific year can be found if we take the average income of the richest faction of a country (the richest 20% of the population) and divide it by that of the poorest faction (the poorest 20%). In this assignment, the Income Ratios that were used were those of 13 different countries. The I.R.'s on both 1980 and 1990 were taken for all these countries and, to find the difference between them, the I.R. for 1990 was divided by the I.R. for 1980, for each country. These new numbers illustrate the change of I.R. between the two years so that we can compare how the P.G. changes in relation to the changes in the I.R.. On this assignment, we use inductive reasoning to examine the data and find a theory (a hypothesis) that would combine the data given in a way that would make sense, based solely on our data. How do we know if the "theory" that we formulate makes sense? In this case we will plot the points (derived from the column "I.R. 1990/1980," going on the x-axis, and the column "Productivity Growth 79-90," on the y-axis). According to how the points are on the graph in relation to the Average Point (0.94,1.45) (point that is an average of all values and which divides the graph into four Quadrants), if 80% of these points are where they would be expected to be to conform to the hypothesis, then there is no reason to reject this hypothesis. If, on the other hand, the majority of the points does not conform to our hypothesis (are not where they were predicted to be), then it is rejected. Another method of reasoning frequently used by Mainstream economists is "deductive knowledge," as opposed to "inductive," described above. Their theory is formulated and only then it is applied to the data. Their theory on this subject suggests that productivity within a country grows when the population has incentives to work harder (or to work more). When the gap between rich and poor increases (an increase in I.R. form 1980-90, resulting in a larger ratio on the column I.R. 1990/1980), so does the population's eagerness to work, therefore increasing the Productivity Growth. Since when one variable goes up the other also goes up, there is a positive (or direct) correlation between the two. Mainstream economists use deductive reasoning to deduce that there exists a positive correlation between the two factors. In short, their hypothesis is that when the Income Ratio increases, the Productivity Growth also increases, since people are more motivated. For this to be true, we would expect a line going up and to the right on the graph, passing by Quadrants II and IV. Most points (80% or more) would have to be on these two Quadrants. This, however, is not the case (see graph), since only about 30.77% of the points plotted satisfy these conditions. Since the original hypothesis was rejected, we might want to see if there is a negative correlation between the two variables (that is, as one goes up, the other goes down). Our new hypothesis would then be "as the Income Ratio increases, the Productivity Growth decreases." Then, in the case of a high I.R., people in lower classes would rationally start to feel insecure and that their work is not being recognized by society, therefore losing motivation and producing less. In this case, since there's a negative correlation, one would expect the line on the graph to go downwards, from left to right, passing on Quadrants I and III. If this hypothesis were valid, 80%+ of the points would have to be on these Quadrants. This is also not the case, for only 69.32% of the points are on the appropriate Quadrants. Like the first, this second hypothesis also has to be rejected. After analyzing these two relationships and seeing that neither is valid, we conclude that there is no direct relationship between the two variables tested. That does not mean that one has no effect on the other (it probably does), only that there may be other factors and influences involved that have not been accounted for in this assignment and that one is not the only factor responsible for the changes in the other.

History and Archaeology of Chinchorro Culture

History and Archaeology of Chinchorro Culture Chinchorro Culture (or Chinchorro Tradition or Complex) is what archaeologists call the archaeological remains of the sedentary fishing people of the arid coastal regions of northern Chile and southern Peru including the Atacama Desert. The Chinchorro are most famous for their detailed mummification practice that lasted for several thousand years, evolving and adapting over the period. The Chinchorro type site is a cemetery site in Arica, Chile, and it was discovered by Max Uhle in the early 20th century. Uhles excavations revealed a collection of mummies, among the earliest in the world. Read more about the Chinchorro Mummies The Chinchorro people subsisted using a combination of fishing, hunting and gatheringthe word Chinchorro means roughly fishing boat. They lived along the coast of the Atacama Desert of northern-most Chile from the Lluta valley to the Loa river and into southern Peru. The earliest sites (mostly middens) of the Chinchorro date as early as 7,000 BC at the site of Acha. The first evidence of mummification dates to approximately 5,000 BC, in the Quebrada de Camarones region, making the Chinchorro mummies the oldest in the world. Chinchorro Chronology 7020-5000 BC, Foundation5000-4800 BC, Initial4980-2700 BC, Classic2700-1900 BC, Transitional1880-1500 BC, Late1500-1100 BC Quiani Chinchorro Lifeways Chinchorro sites are primarily located on the coast, but there are a handful of inland and highland sites as well. All of them seem to follow a sedentary lifeway reliant on maritime resources. The predominant Chinchorro lifestyle appears to have been an early coastal sedentism, supported by fish, shellfish and sea mammals, and their sites all contain an extensive and sophisticated fishing tool assemblage. Coastal middens indicate a diet predominated by sea mammals, coastal birds, and fish. Stable isotope analysis of the hair and human bones from the mummies indicates that nearly 90 percent of Chinchorro diets came from maritime food sources, 5 percent from terrestrial animals and another 5 percent from terrestrial plants. Although only a handful of settlement sites have been identified to date, Chinchorro communities were likely small groups of huts housing single nuclear families, with a population size of approximately 30-50 individuals. Large shell middens were found by Junius Bird in the 1940s, adjacent to the huts at the site of Acha in Chile. The Quiana 9 site, dated to 4420 BC, contained the remains of several semicircular huts located on the slope of an Arica coastal hill. The huts there were built of posts with sea mammal skin roofs. Caleta Huelen 42, near the mouth of the Loa River in Chile, had several semisubterranean circular huts with superimposed floors, implying long-term ongoing settlement. Chinchorro and the Environment Marquet et al. (2012) completed an analysis of environmental changes of the Atacama coast during the 3,000-year span of the Chinchorro culture mummification process. Their conclusion: that the cultural and technological complexity evidenced in mummy construction and in fishing gear may have been brought about by environmental changes. They point out that the micro-climates within the Atacama desert fluctuated during the end of the Pleistocene, with several wet phases that resulted in higher ground tables, higher lake levels, and plant invasions, alternating with extreme aridity. The latest phase of the Central Andean Pluvial Event occurred between 13,800 and 10,000 years ago  when human settlement began in the Atacama. At 9,500 years ago, the Atacama had an abrupt onset of arid conditions, driving people out of the desert; another wet period between 7,800 and 6,700 brought them back. The effect of ongoing yo-yo climates was seen in population increases and decreases throughout the period. Marquet and colleagues argue that cultural complexitythat is to say, the sophisticated harpoons and other tackleemerged when the climate was reasonable, populations were high and plentiful fish and seafood were available. The cult of the dead exemplified by the elaborate mummification grew because the arid climate created natural mummies and subsequent wet periods exposed the mummies to the inhabitants at a time when dense populations spurred cultural innovations. Chinchorro and Arsenic The Atacama desert where many of the Chinchorro sites are located has elevated levels of copper, arsenic and other toxic metals. Trace amounts of the metals are present in the natural water resources  and have been identified in the hair and teeth of the mummies, and in the current coastal populations (Bryne et al). Percentages of arsenic concentrations within the mummies ranges from Archaeological Sites: Ilo (Peru), Chinchorro, El Morro 1, Quiani, Camarones, Pisagua Viejo, Bajo Mollo, Patillos, Cobija (all in Chile) Sources Allison MJ, Focacci G, Arriaza B, Standen VG, Rivera M, and Lowenstein JM. 1984.

Consultancy business report - Term Paper Example organization that has progressed or has a vision for a brighter future is can be gagged by an analysis of how it takes care or manages its human resources. The saddest fact in the recent trend has been to assume or overlook the roles human resources play in a particular organization. With the current age of automation, scores of managers looks upon the machines as vital components for executing their business strategies. They tend to shift their focus from the human aspect of their business operations and concentrate on the technological aspect. On the same note, the current business age calls for comprehensive strategies from business organizations that aim to remain in the market. With globalization as the target mark for many companies, every business organization will strive to achieve it. However, the only route for the achievement of the same lays in the careful planning and implementations of an all inclusive market related plans that are termed as corporate strategies. The fo rmulation and implementations of corporate strategies has been seen as a decisive tool in the growth of a company only if a proper correlation between the same and the human capital has been made. For a long time, human capital has been only valued in terms of their labor output per unit; with their roles in the implementation of corporate ignored in most cases. This paper looks into the links between corporate strategy and human resources with due considerations to Sedibeng breweries from South Africa. A strategy is simply a plan that is aimed at making a company or a business organization to market itself to attain a larger share of market from its competitors (Miller, 1989). Thus, the process is entirely a marketing plan that is aimed at making that particular business unit to have a relatively different and unique platform that will distinguish its activities from those of its competitors, to gain a competitive advantage. If the management’s plan of making the company to gain a

Improving Participation of the Staff Meeting in a University Essay

Improving Participation of the Staff Meeting in a University - Essay Example As I noted in my earlier Action Research Project Plan, which basically became the manual for this research, Hill defines management as â€Å"getting things done through and with other people† (Hill, ibid.). As the time has elapsed between writing that plan and concluding this research, I have become even more convinced that co-operation (the â€Å"through and with other people† of Hill’s notion) is an essential behaviour if the work of our group is to prosper.It will be recalled from that project plan that I have chosen to pursue this work through the qualitative paradigm of Action Research as a practitioner- researcher. I hoped during the research to improving my own skills in facilitating meetings and to improve practice through the implementation of change in the way meetings are run in my workplace. To be a successful practitioner- researcher, I understood that I must achieve what Ritchie and Spencer (1994: 173) have called â€Å"actionable outcomes† i n order to bring about the organisational change that I seek but that I must also maintain the academic rigour of the work. I found guidance for my approach to keeping this balance in the research in the work in Argyris' (1999: 432) who has made the social scientist's dilemma of choosing between rigour and relevance central to the way in which he has adapted Lewin's Action Research heritage. He concludes that: From the action researcher's perspective, the challenge is to define and meet standards of appropriate rigor without sacrificing relevance. (Italics in the original) Thus in mid November 2005 I began, with some confidence, to apply the wide range of data gathering techniques (including, collection of documentary evidence, observation, questionnaire, group discussion and analysis of my own reflective research journal) that I had planned earlier. I expected to do this within a highly practitioner centred approach that ensured academic appropriateness, rigour and relevance within the research as a whole. 2. An account of the situation and action to improve it I began the research by applying the data gathering methods that had been foreseen in the Action Research Project Plan. In this section I will report on the usage of these methods and demonstrate how they helped in the data collection process. Whilst each of these tools was used throughout the work, the emphasis and importance of each changed as the programme evolved and moved through the various cycles of the research from Reconnaissance to Review and Reflection. The programme of Reconnaissance data collection took place between the 1st November 2005 and Christmas of the same year with the data being analysed during the Christmas/New Year break. 2.1 Reflective research diary Firstly, I began to write my reflective research journal. This was quite a difficult task to maintain because although the early enthusiasm ensured that I sat down regularly at my computer I found that it was difficult to make the writing "reflective". I began to ask myself "what is it that makes this document a reflective journal and not just a diary" As a result of this difficulty I adopted an approach whereby I first wrote down a record of events and made notes of things that people had said or done during the period that I was recording. This was the diary phase of journal writing and was quite easy. I then got into the habit of going over the work and using the automatic highlighter, would colour code things that struck me as relevant to the ongoing research. It was through this routine that I developed my reflective skills and, for example, identified for myself the fact that one of my co-researchers had tendency to support

Argument Against Gun Control :: Second Amendment The Right To Bear Arms

Gun Control is when you keep firearms plus guns away from people. Many people think that gun control is right because they think keeping people away from guns will reduce the amount of deaths each year. They also think that guns cause many of the deaths that had been committed each year. Also when ever people hear the word gun, the thoughts are of violence and negativity. Many people, myself included think gun control is wrong because we know that it is not necessary, since we know that guns were not involved in many of the deaths caused each year. While many other people disagree and think it is good because of the safety for people. In this essay I will tell you why gun control is unnecessary and why there shouldn?t be any gun control at all. There have been many gun control laws established throughout the U.S., but they vary from state to state. For example, in Colorado you can purchase any type of gun: handgun, machine gun, shotgun, rifle, automatic rifle, etc. at the age of 18, while in other places you would need a hunting license.1 I think this is unfair because when I?m at the age of 18 I would want to buy a gun, but I can?t because I?m living in California and another 18 year old could in Colorado. Also, another example is that in some states, they allow citizens to carry concealed weapons, while in other states citizens can?t. I don?t think this is fair at all because I think they should make laws that suits the whole U.S., and not make different laws in different states. Another reason that makes me think that they shouldn?t have different gun control laws in different places is because I knew a person that buys guns in New York, and some how got them over here and sells them to people by tripling the price. I have asked him how he got them over here, but he never told me how he did it. He told me that he has done this for many years until one time he got caught when he was selling them and was jailed for 6 or 7 months. If gun control laws were applied the same in every place he could of never have gotten the guns. This also means that criminals could have done the same thing that my friend had done, but not sell the guns but use them to do bad things.

The Wandering of King Lear’s Mother Essay - 1597 Words

The Wandering of King Lear’s Mother After he experiences all kinds of humiliation done by Goneril, and finds his messenger Kent in the stocks, King Lear, in Act 2 Scene 4, conjures up the â€Å"mother† to express his outburst of rage and physical symptom sensations: O! how this mother swells up toward my heart; Hysterica passio! down, thou climbing sorrow! Thy element’s below. Where is this daughter? (II.iv.56-58) Who is this â€Å"mother†? Or what is this â€Å"mother†? As many critics have identified, this â€Å"mother† is another name for the womb, matrix, or uterus. That the â€Å"mother swells up† points to the disease called hysteria. Yet, who is responsible for the rise or wandering of Lear’s â€Å"mother†? Does†¦show more content†¦Ã¢â‚¬Å"Besides the English name of the mother, or the suffocation of the mother, the disease goes under several other names† (Camden 391). As Jorden writes, â€Å"This disease is called by diverse names amongst our Authors, Passio Hysterica, Suffocatio, Prafocatio, and Strangulatus uteri, Caducus matrices, etc.† (5) We may wonder what has Lear to do with the mother, since his anatomy is obviously deficient of such a disease. How does the mother affect Lear as well as his relationship to other characters? Is Lear a male hysteric? It is obvious that the mother revealed and represented by Lear’s words is a complex representational figure, simultaneously â€Å"real† and â€Å"fantasized†. It is â€Å"real† in the sense that Lear can in no way deny or repress the mother’s urgent emergency and her terrifying power and wrath. 1 It is â€Å"fantasized† in the sense that there is simply no bodily space to mark her presence. On the other hand, the mother can be viewed as a metaphor employed by Lear to express his emotional and physical states. Given the entire absence of literal mothers in the play, this conjuring up of the mother seems particularly significant and meaningful. The purpose of this paper is to explore the theme of hysteria and to trace the wandering of this mother and its manifestations in Shakespeare’s King Lear from a feminist perspective.
