Nature and Nature in Cognitive Development Essay Example for Free

Nature and Nature in Cognitive Development EssayWhy are both nature and boot important in perceptual go againstment? How do both help a babys brain and sensory organs to develop? The question of whether nature or nurture is more important in terms of perceptual development has bee long debated. In ecumenic, there are two theories that explain how humans develop these perceptions. The Nativists study that our brains are built or hardwired to cognize certain stimuli by both design and construction. In contrast, an Empiricist would say that we learn through experience how to embrace things. thither was an experiment done by Nativist researchers that sought to determine how very young mammals are able to perceive. The data concluded that early infants were able to perceive rather a lot before they really had a chance to learn anything. Gibson and Walks the visual cliff experiment was one such experiment, in this test both young animals and 6 month old human infants were taken to a side of a visual cliff, the test subjects would negate the clearly deep drop. This indicated that children can perceive visual depth and that visual depth dominates even touch information.Additionally, studies drive home been done that show babies can descry faces and that they often prefer the visual stimulation of carton faces as opposed to the same features arranged at random. In other tests it was shown that babies can also recognize whether or not and object is coming directly at their face or not. These experiments show that even the undeveloped infant brain has considerable contentedness for perceptual capabilities. In contrast, several Empiricists experiments have been done as well. In one such study, scientists sought to determine the effects of depriving developing animals from perceptual stimulations.These tests have consistently shown that the longer the subject is deprived, the more severe the consequences. For example, humans are sometimes born without sight, due to a clouded cornea. Later in deportment some elect to have surgery to repair this clouded cornea. The result is sight, these people can see but they cannot perceive what it is that they see. As time goes on they slowly learn to distinguish one object from another, but this is however quite easily interrupted. Often changing an objects position or context is quite enough to slow down or prevent recognition.To conclude, although some argue that perception is due to nature, while others argue for nurture, it may in fact be that the two factors are interdependent and rely on each other. Support for this idea comes from an experiment that studied rats and found that those raised in a perceptually restricted environment had smaller brain development than those raised in an enriched environment, suggesting that while we are born with innate capabilities we need the environment to ensure we develop our abilities to perceive well.The perceptual capabilities we have at birth must be st rengthened continuously through perceptual stimulation, furthermore, it would seem that perception in general follows the use it or lose it principle. Just as unused muscles become week, so to do our senses if left unused. Nature and nurture are both essential to health y perceptual development stimulation begins in the womb and quickly follows all the way through adulthood.

The Reason Why Women Live Longer Than Men Essay Example for Free

The Reason Why Women Live Longer Than Men EssayScientists are finally beginning to understand matchless of lifes enduring mysteries why women live, on average, longer than men. The new query describes how athleticss to the DNA of the mitochondria can account for differences in the life expectancy of males and females. Mitochondria, which come through in almost all zoology cells, are vital for life because they convert our food into the energy that powers the body.Dr Damian Dowling and PhD student Florencia Camus, from Monash School of Biological Sciences in the U. S., worked with Dr David Clancy from Lancaster University to endanger differences in longevity and biological ageing across male and female fruit flies that carried mitochondria of different origins. They found that genetic variation across these mitochondria were tested predictors of life expectancy in males, but not in females. Dr Dowling said the results point to numerous mutations within mitochondrial DNA tha t affect how long males live, and the speed at which they age. He said Intriguingly, these same mutations have no effects on patterns of ageing in females they only affect males. All animals possess mitochondria, and the tendency for females to make it males is common to many different species.Our results therefore suggest that the mitochondrial mutations we have uncovered will generally cause faster male ageing across the animal kingdom. The researchers said the mutations can be entirely attributed to a quirk in the way that mitochondrial genes are passed down from parents to offspring. Dr Dowling said While children receive copies of most of their genes from some(prenominal) their mothers and fathers, they only receive mitochondrial genes from their mothers. This means that evolutions quality control process, known as natural selection, only screens the quality of mitochondrial genes in mothers. If a mitochondrial mutation occurs that harms fathers, but has no effect on mothers , this mutation will slip through the gaze of natural selection, unnoticed.Over thousands of generations, many such mutations have accumulate that harm only males, while leaving females unscathed. The study builds on previous findings by Dr Dowling and his team who investigated the consequences of maternal inheritance of mitochondria in causing male infertility. Dr Dowling added Together, ourresearch shows that the mitochondria are hotspots for mutations affecting male health. What we seek to do now is investigate the genetic mechanisms that males might arm themselves with to nullify the effects of these harmful mutations and remain healthy.

Life and c areer Essaysingers parents were Viennese Jews who escaped the German annexation of Austria and fled to Australia in 1938. His grandparents were less fortunate they were taken by the Nazis to Lodz, and were never heard of again. 1 Singers father imported tea and coffee, term his mother practised medicine. He attended Scotch College. After leaving school, Singer studied law, history and philosophy at the University of Melbourne, gaining his degree in 1967. He received an MA for a thesis entitled Why should I be moral? n 1969. He was awarded a scholarship to study at the University of Oxford, obtaining a B. Phil in 1971 with a thesis on civil disobedience, supervised by R. M. Hare, and subsequently published as a book in 1973. 2 After spending two years as a Radcliffe lecturer at University College, Oxford, he was visiting professor at New York University for 16 months. He returned to Melbourne in 1977, where he has spent just or so of his career, apart from many visi ting positions internationally, and until his move to Princeton in 1999.Animal LiberationPublished in 1975, Animal Liberation3 was a major formative influence on the animal liberation movement. Although Singer rejects rights as a moral non much(prenominal) independent from his usefulism based on stakess, he accepts rights as derived from utilitarian principles, particularly the principle of minimizing suffering. 4 Singer allows that animal rights are non exactly the same as merciful rights, writing in Animal Liberation that there are obviously important differences between human and other animals, and these differences must give full to some differences in the rights that each have. 5So, for example an animal does not have the right to a good education as this is cerebrateingless to him, just as a male human does not have the right to an abortion. But he is no more skeptical of animal rights than of the rights of women, beginning his book by defending just such a comparison a gainst bloody shame Wollstonecrafts 18th-century critic Thomas Taylor, who argued that if Wollstonecrafts reasoning in defense of womens rights were correct, then brutes would have rights too.Taylor thought he had produced a reductio ad absurdum of Wollstonecrafts view Singer regards it as a sound logical implication. Taylors modus tollens is Singers modus ponens. In Animal Liberation, Singer argues against what he calls speciesism discrimination on the grounds that a existence belongs to a certain species. He holds the interests of all beings capable of suffering to be worthy of equal condition, and that giving lesser musing to beings based on their having wings or fur is no more justified than discrimination based on skin color.In particular, he argues that while animals show lower intelligence than the average human, many severely retarded humans show equally diminished mental capacity, and intelligence so does not provide a basis for providing nonhuman animals any less consi deration than such retarded humans. Singer does not specifically contend that we ought not employment animals for food inso further as they are raised and killed in a way that combat-readyly avoids the inflicting of pain, but as such farms are a couple of(prenominal) and far between, he concludes that the most practical solution is to adopt a vegetarian or vegan diet.Singer also condemns most vivisection, though he believes animal experiments may be acceptable if the benefit (in terms of improved medical treatment, etc. ) outweighs the harm done to the animals used. 6 Due to the subjectivity of the term benefit, controversy exists about this and other utilitarian views. But he is clear enough that humans of comparable sentience should also be candidates for any animal experimentation that passes the benefit test.So a monkey and a human infant would be equally available for the experiment, from a moral point of view, other things being equal. If performing the experiment on the in fant isnt justifiable, then Singer believes that the experiment shouldnt happen at all alternatively, the researchers should pursue their goals using computer simulations or other methods. Applied ethics His most comprehensive work, Practical Ethics,7 analyzes in detail why and how beings interests should be weighed.His principle of equality encompasses all beings with interests, and it requires equal consideration of those interests, whatever the species. The principle of equal consideration of interests does not dictate equal treatment of all those with interests, since different interests warrant different treatment. All have an interest in avoiding pain, for instance, but relatively few have an interest in cultivating their abilities.Not only does his principle justify different treatment for different interests, but it allows different treatment for the same interest when diminishing marginal utility is a factor, favoring, for instance, a starving persons interest in food over the same interest of someone who is only roughly hungry. Among the more important human interests are those in avoiding pain, in developing ones abilities, in satisfying basic needs for food and shelter, in enjoying warm individual(prenominal) relationships, in being free to pursue ones projects without interference, and many others.The fundamental interest that entitles a being to equal consideration is the capacity for suffering and/or manipulation or happiness mice as well as human beings have this interest, but stones and trees do not. He holds that a beings interests should always be weighed according to that beings cover properties, and not according to its belonging to some abstract group such as a species, or a set of possible beings, or an earlier stage of something with an as yet unactualized potential.He favors a journey model of life, which measures the misemployness of taking a life by the degree to which doing so frustrates a life journeys goals. So taking a lif e is less wrong at the beginning, when no goals have been set, and at the end, when the goals have either been met or are unlikely to be accomplished. The journey model is tolerant of some frustrated desire, explains why persons who have embarked on their journeys are not replaceable, and accounts for why it is wrong to mystify a miserable life into existence.Although sentience puts a being within the sphere of equal consideration of interests, only a personal interest in continuing to live brings the journey model into play. This model also explains the priority that Singer attaches to interests over trivial desires and pleasures. For instance, one has an interest in food, but not in the pleasures of the palate that might distinguish eating steak from eating tofu, because nutrition is instrumental to many goals in ones life journey, whereas the desire for meat is not and is therefore trumped by the interest of animals in avoiding the miseries of factory farming.In order to avoid b ias towards human interests, he requires the idea of an impartial standpoint from which to compare interests. This is an ornateness of the familiar idea of putting oneself in the others shoes, adjusted for beings with paws or flippers. He has wavered about whether the precise aim is the total amount of satisfied interests, or instead the most satisfied interests among those beings who already exist prior to the decision one is making.Both have liabilities. The total view, for instance, seems to lead to Derek Parfits Repugnant Conclusion8 that is, it seems to imply that its morally stop to have an enormous population with lives barely worth living rather than a smaller population with much happier lives. The prior-existence view, on the other hand, seems questionably absent-minded to the harm or benefit one can do to those who are brought into existence by ones decisions.The second edition of Practical Ethics disavows the first editions clue that the total and prior-existence vi ews should be combined in such a way that the total view applies to sentient beings who are not self-conscious and the prior-existence view applies to those who are. This would mean that rats and human infants are replaceable their painless death is permissible as long as they are replaced whereas human adults and other persons in Singers expanded sense, including heavy(p) apes, are not replaceable.The second edition dispenses with the requirement of replacement and the consequent high population numbers for sentient beings. It asserts that preference-satisfaction utilitarianism, incorporating the journey model, applies without invoking the first editions suggestion about the total view. But the details are fuzzy and Singer admits that he is not entirely satisfied with his treatment of choices that involve bringing beings into existence. Ethical rent is justifiable by reasons that go beyond prudence to something bigger than the individual, addressing a larger audience.Singer thi nks this going-beyond identifies moral reasons as somehow universal, specifically in the mandate to love thy neighbor as thyself, interpreted by him as demanding that one give the same weight to the interests of others as one gives to ones own interests. This universalizing step, which Singer traces from Kant to Hare, is significant and sets him apart from moral theorists from Hobbes to David Gauthier, who regard that step as flatly ir keen.Universalization leads directly to utilitarianism, Singer argues, on the strength of the thought that my own interests cannot count for more than the interests of others. victorious these into account, one must weigh them up and adopt the course of action that is most likely to maximize the interests of those affected utilitarianism has been arrived at. Singers universalizing step applies to interests without reference to who has them, whereas a Kantians applies to the judgments of discerning agents (in Kants kingdom of ends, or Rawlss Origin al Position, etc. ).Singer regards Kantian universalization as unjust to animals. Its their capacity for suffering/happiness that matters morally, not their deficiency with respect to shrewd judgment. As for the Hobbesians, Singer attempts a response in the final chapter of Practical Ethics, arguing that self-interested reasons support adoption of the moral point of view, such as the riddle of hedonism, which counsels that happiness is best found by not looking for it, and the need most people feel to relate to something larger than their own concerns. Abortion, euthanasia and infanticide consonant with his general ethical theory, Singer holds that the right to physical integrity is grounded in a beings ability to suffer, and the right to life is grounded in, among other things, the ability to plan and previse ones future. Since the unborn, infants and severely disabled people lack the latter (but not the former) ability, he states that abortion, painless infanticide and euthanasi a can be justified in certain peculiar(prenominal) circumstances, for instance in the case of severely disabled infants whose life would cause suffering both to themselves and to their parents.In his view the central literary argument against abortion is It is wrong to kill an innocent human being a human fetus is an innocent human being therefore it is wrong to kill a human fetus. He challenges the second premise, on the grounds that its reference to human beings is ambiguous as between human beings in the zoological sense and persons as rational and self-conscious. There is no sanctity of human life that confers moral protection on human beings in the zoological sense.Until the capacity for pain develops after 18 weeks of gestation, abortion terminates an existence that has no intrinsic value (as opposed to the value it might have in virtue of being valued by the parents or others). As it develops the features of a person, it has moral protections that are comparable to those th at should be extended to nonhuman life as well. He also rejects a backup argument against abortion that appeals to potential It is wrong to kill a potential human being a human fetus is a potential human being therefore it is wrong to kill a human fetus.The second premise is more plausible, but its first premise is less plausible, and Singer denies that what is potentially an X should have the same value or moral rights as what is already an X. Against those who stress the continuity of our existence from conception to adulthood, he poses the example of an embryo in a dish on a laboratory bench, which he calls Mary. Now if it divides into two identical embryos, there is no way to answer the question whether Mary dies, or continues to exist, or is replaced by Jane and Susan.These are absurd questions, he thinks, and their absurdity casts doubt on the view that the embryo is a human being in the morally significant sense. Singer classifies euthanasia as voluntary, involuntary, or non- voluntary. (For possible similar historical definitions of euthanasia see Karl Binding, Alfred Hoche and Werner Catel. ) Given his consequentialist approach, the difference between active and passive euthanasia is not morally significant, for the required act/omission doctrine is untenable killing and letting die are on a moral par when their consequences are the same.Voluntary euthanasia, undertaken with the consent of the subject, is supported by the autonomy of persons and their freedom to waive their rights, especially against a legal background such as the guidelines developed by the courts in the Netherlands. Non-voluntary euthanasia at the beginning or end of lifes journey, when the capacity to reason about what is at stake is budding or lost, is justified when swift and painless killing is the only alternative to suffering for the subject.

Analysis Of Gdp Determinants Statistics Economics Essay

Analysis Of Gdp Determinants Statistics Economics EssayThe aim of our report is to identify the factors which affects gross domestic product for both country. In our report we be analyzing such factors in relation to Indias gross domestic product. The report will be dealing with throwback analysis, supposal testing, mean, median, mode etc of such factors which be in strung-out proteans and their affect on gross domestic product which is a dependent covariant.2. IntroductionThe report revolves around an exploratory instruct. It includes analyzing the statistical data of Indias GDP and other factors handle Employment to people proportionality, FDI, commonwealth for the past 20 years. Our aim is to identify the dependence of above mentioned factors on GDP of India and results of the atavism analysis. Here we take GDP as the dependent variable and other three factors as the independent variables. Before getting into analysis we look into the substitute measures of each var iable utilise in the report for analyzing simple regression, hypothesis testing and calculating the mean and median nurses.GDPLending Interest RatesFDIPopulationEmployment to population dimension2.1) GDPGDP forms the dependent variable of our research study. GDP is an indicator of overall economic welfargon of a country. It is the sum total of the final steady-goings and function produced within the borders of the nation. In other words, summing up the consumption, government intake, enthronisations and net exports results in the GDP growth rate of a country. It is considered to be a very in-chief(postnominal) element as it helps in estimating the health of countrys miserliness. Calculating the GDP is not an easy task be practice of which they argon left to be calculated by the economists. GDP growth rate of an economy is dependent on various factors equivalent FDI, population to employment proportionality, lending enkindle rate, population etc. Governments closely see out the GDP as it measures the economic performance of the country. If GDP rises it means the economy has grown and vice versa.GDP is criticized on various grounds like it does not talks or so(predicate) the spending power, distribution of income or well being of countrys inhabitant.Formula of calculating GDPGDP=C+I+G+(X-M)Where,C=consumptionI= investitureG=government expenditure (X-M) =Net ExportsThe independent variables (Population, Lending Interest rates, FDI, Employment to population dimension etc ) that we are development in the research analysis affect each of these above mentioned components.The data related to GDP has been shown in the appendix 9.12.2 ) Employment to population ratioIt is taken as an independent variable in our study. We attempt to measure the impact of this ratio on GDP growth in India. Employment to population ratio basically means the ratio of the total working age of the labor force employed over total population. Following formula is utilise in calculating the ratioEmployment to population ratio=Employed Persons/ Total non-institutionalized civilian population *100This ratio does not bear under(a)rate problems relating to unemployed persons and other discouraged workers that enter or exit the labor force.The data of employment ratio is shown in appendix 9.12.3) FDI unlike need investment is an independent variable in our research report. We try finding out the impact of FDI on GDP growth rate.In simple words it is an investment made by one company in a given country in another company based or set up in another country.FDI has been a major source of managerial skills, technology, capital and access to market desired for sustained economic development and growth in the recent past. All the Countries are involved in inviting more and more of overseas direct investment to come and invest in their country resulting in rapid economic growth. FDI is considered to be an important factor in facilitating growth, however, it wil l result in growth only if the inflows are carefully managed and invested.The related data is included in the appendix 9.1 for the past 20 years . All the inferences related to FDI has been drawn on the basis of such data.2.4) PopulationThe growth of population has always been a debating issue. There is no conclusion as to it is negative or corroboratory for growth of an economy. Population and economic growth are unified to each other in a way that, population increases due to high economic growth leading to early marriages and hiking birth rates and checking on the mortality rates by providing healthy environment to the citizens. Higher population also depresses economic growth through diminishing returns. (Becker, Glaeser, and Murphy 1999, p. 145) In our study we attempt to study the impact of population on economic growth which is expressed as the real GDP per capita.The data regarding population for past 20 years has been included in the appendix 9.1. All the analysis related to it has been done on the basis of such data and various results has been drawn on such basis.2.5) Lending Interest RateLending Interest rate is the amount of participation charged by a lender from a borrower in case of loan being offered. A countrys real GDP and interest rates are interlinked in a variety of means. They have a direct consanguinity, i.e., high lending rate results in high growth for the economy. The dependence of GDP on Lending Interest Rate can be canvas in the analysis of the study.The related data regarding interest rate is included in appendix 9.13. Tools used for research studyThe statistical tools used in our research study with the objective of finding the dependence of GDP on various independent variables like, Population, Lending interest rates, FDI, Employment to population ratio are reasoning backward Analysis, Mean, Median, Mode, dead reckoning TestingSteps involved in analysisOur first step was to scrutinize and identify the factors responsible f or GDP growth of a nation.Next, we tried locating data of the identified factors for the past 20 years.Than we tried finding relationship of various factors with the GDP of a nation.The data was than constructed and summarised in a proper manner to conduct regression analysis.SPSS software was used to conduct the regression analysis and hypothesis testing.All the data and factors collected are using the secondary sources, i.e., Internet and Journals.4. Data DescriptionN i.e. the number of observations for our research is 20.There are two types of dataQualitativeQuantitativeQualitative data deals with categorical measurement and is not measured in terms of numeric values. For our study the qualitative factors can be like Market Risk, Business surmisal etc, which affects the GDP but due to their qualitative nature we overlooked them of the study.Quantitative data deals with the numerical measurement of the database. Relating to our study, the quantitative data factors are Population , GDP, Lending interest rates, FDI etc.We have limited our research taking in account only the quantitative data.Data can also be time series or cross sectionalCross sectional data is the data for a given point of time analyzing the differences among the subjects.Whereas time series data is implicated with the data over a spread time courseIn our report we are using time-series data, for 20 years i.e. from 1991 to 2010.Regression AnalysisRegression Analysis means scrutinizing the relationship in the midst of a dependent and independent variable. subsequently conducting an analysis, regression statistics is helpful in identifying the dependent variable when the independent variables are unknown.Dependent Variable- GDP growth of IndiaIndependent variable- FDI, Employment to Population ratio and Real Interest RateThe regression equation isY=b1X1+b2X2+.+EIn the above equation-Y= dependent variableX1, X2 =independent variablesb1, b2 =coefficients describing effect of independent vari ables on the dependent variablesE= break termIn our study, the equation looks like,GDP=b1F1+b2F2+b3F3++bnfnWhere,F1 to Fn= independent variable factorsHypothesis testingHypothesis testing is the test of significance wherein we identify the likelihood that an assumption is true, and at what likelihood we would hold the assumption as true. The assumption made is referred as the Null hypothesis and is denoted by H0 and an alternate hypothesis is defined known as an Alternative Hypothesis and is denoted by Ha. The rationale behind this test is to hold null hypothesis to be true and then performing the study on the argument in question. at a time the hypothesis is defined and data is collected and constructed, following steps of hypothesis are followedA critical region of size alpha is determined using the sample distribution of the test statisticsUsing the sample data, identify the values of test statisticsThe last step is confirming that the value of test statistics make outs under t he critical region defined if no, we get hold of the null in favour of the alternative hypothesis and if yes, we rule in the null hypothesis.5). Variables considered as independent in hypothesis and doing regression analysisIn doing the analysis of various factors affecting GDP growth some of the factors which is been considered as the variables are FDI, Employment ratio, Population and Lending interest rate as they impact directly in the growth of GDP for any country. The factors are denoted by r and following relation in the midst of the factors as stated above and the regression can be explained under5.1) Population (H1)Although increase in population has a negative impact on the economy of any country. However, such increase allows availability of labor at cheap rates which attracts the companies or firms to make more investment in the form of external direct investment or FIIs that helps to give upward thrust in GDP.5.2) Foreign Direct Investment(H2)It can be argued on the grounds of proven facts that Foreign Direct Investment has a positive relation for boosting the economic growth of any country which results in increasing the GDP of the country. FDI allows the bills to come in the economy which creates opportunities to increase growth of the economy.5.3) Employment Ratio(H3)It also affects the economy which indeed affects GDP growth as with the increase in the employment more expenditure will have to be incurred which in turn affect countrys GDP5.4) Lending Interest Rate(H4)If the interest rate increases it will lead to less money circulation in the economy. The banks and financial institutions of the country will not able to lend money as the people will not be willing to accept because the increase in interest rate will attract more interest expense and hence will resist to it. This will result in decrease in the consumption which will bend the GDP down and secondly money circulation will also reduce which result in the fall in GDP growth. in t hat locationfrom the whole discussion can be summarized in the following manner-H1- Increase in population lead to increased GDP. Hence it has a positive relationH2- Increase in FDI Increases GDP. It also has a positive relationH3- Increase in employment leads to increase in GDP. It shows positive relationH4- Increase in Interest rate leads to fall in GDP. It has a negative relation6). Regression results6.1) Employment Regression (Appendix 9.3.1)In this regression model,Employment ratio is an independent variable and on X-axis.GDP is a dependent variable and on y-axis.After doing data analysis of this model, we cogitate that the regression equation for this isHere,is an intercept which is 1.736is a shift of this equation which is -2.958 Estimated valueIf employment ratio is increase by 1, there is decrease in GDP by 2.958.There is negative linear relationship between GDP and employment ratio.Now if we talk about correlation between these two variable which is R.= +(.720)= +.849In this + sign shows that correlation is positive and is .849Now is .72 which shows that 72 % variance in GDP is explained by employment ratio.Now if we talk about this model whether it is life-threatening or bad, we have to check two condition.should be highIn this is high.Hypothesis test = 0 (no linear relationship between X and Y) 0 (linear relationship between X and Y)This is decide by t statisticsNow, = -6.80 Standard errorvalue is .000 and we assume is .05 which is greater than p-value.Hence we reject .So we conclude that it is a good regression model.6.2) FDI Regression (Appendix 9.3.2)In this regression model,FDI is an independent variable and on X-axis.GDP is a dependent variable and on y-axis.After doing data analysis of this model, we conclude that the regression equation for this isHere,is an intercept which is 3.894is a side of meat of this equation which is 0.029 Estimated valueIf FDI is increase by 1, there is increase in GDP by .There is positive linear relations hip between GDP and FDI as the slope is positive.Now if we talk about correlation between these two variable which is R.= +(.782)= +.884In this + sign shows that correlation is positive and is .884Now is .78 which shows that 78 % variance in GDP is explained by FDI.Now if we talk about this model whether it is good or bad, we have to check two condition.should be highIn this is high.Hypothesis test = 0 (no linear relationship between X and Y) 0 (linear relationship between X and Y)This is conclude by t statisticsNow, = 8.025 Standard errorvalue is .000 and we assume is .05 which is greater than p-value.Hence we reject .So we conclude that it is a good regression model.6.3) Lending interest rate (Appendix 9. 3.3)In this regression model,Lending interest rate is an independent variable and on X-axis.GDP is a dependent variable and on y-axis.After doing data analysis of this model, we conclude that the regression equation for this isHere,is an intercept which is 2.088is a slope of this equation which is -1.066 Estimated valueIf lending interest rate increases by 1, there is decrease in GDP by 1.066.There is negative linear relationship between GDP and lending interest rate as the slope is negative.Now if we talk about correlation between these two variable which is R.= +(.466)= +.683In this + sign shows that correlation is positive and is .849Now is .46 which shows that 46 % variance in GDP is explained by employment ratio.Now if we talk about this model whether it is good or bad, we have check two condition.should be highIn this is high.Hypothesis test = 0 (no linear relationship between X and Y) 0 (linear relationship between X and Y)This is conclude by t statisticsNow, = -3.964 Standard errorvalue is .001 and we assume is .05 which is greater than p-value.Hence we reject .So we conclude that it is a good regression model.6.4) Population Regression (Appendix 9.3.4)In this regression model,Population is an independent variable and on X-axis.GDP is a depe ndent variable and on y-axis.After doing data analysis of this model, we conclude that the regression equation for this isHere,is an intercept which is 3.894is a slope of this equation which is 0.029 Estimated valueIf population is increase by 1, there is increase in GDP by 3.60There is strong positive linear relationship between GDP and POPULATION as the slope is positive.Now if we talk about correlation between these two variable which is R.= +(.819)= +.905In this + sign shows that correlation is positive and is .905Now is .81 which shows that 81 % variance in GDP is explained by population.Now if we talk about this model whether it is good or bad, we have to check two condition.should be highIn this is high.Hypothesis test = 0 (no linear relationship between X and Y) 0 (linear relationship between X and Y)This is conclude by t statisticsNow, = 9.031 Standard errorvalue is .000 and we assume is .05 which is greater than p-value.Hence we reject .So we conclude that it is a good regression model.7) ConclusionThe effect of factors like employment ratio, foreign direct investment, lending interest rate and population on GDP of India are considered as important variables which we have tried to explain with the help of regression analysis and hypothesis testing. By considering the data of past 20 years we have also calculated its mean, median, mode, Variance, standard deviation (appendix 2). We have one dependent variable that is GDP and four independent variables which are FDI, employment ratio, population, and interest rate.According to multiple regressions, the equation for the model isWhere x1, x2, x3, x4 are the independent variable, estimated value E(y) is evaluate by these variable. In our report, we have taken separate simple regression modelsRegression analysis cannot interpret as a procedure for establishing a cause and effect relationship between variables. It can only show that how such(prenominal) these variables are related or associated with e ach other. Regression equation tells us about mean value of y for given value of x. According to Hypothesis test, all four regression model is good model and it estimates the mean value for these independent variables with less errors. The models also shows the relationship between GDP and these independent variables and their effect on GDP.

Personal Reflection on Leadership

Personal Reflection on LeadershipIn my brief professional cargoner at IBM, I was part of a software development group where I was the youngest and least experienced person. I vividly remember that we had a team film director, highly experienced and professional but an ineffective attractor. He would perform his tasks but did not go that extra mile. On the other hand, one of my teammates-very less experienced compared to the manager was a true leader, his duties did not ask him of any such commitments, but he always went the extra mile to help the team. He took me under his wing, incite others in the team, and found innovative ways to solve the problem. He created an environment for high competence. He gave me so much confidence with his mentoring that I was acting at the highest level in no time. He created a synergy among the team that even the client praised. His actions re geniused me of a saying from Jack Welch, former chief operating officer of GE Before you are a leader, success is all about growing yourself. When you become a leader, success is all about growing others. In my opinion, he was the true leader because he positioned the team at the centre of everything and took the responsibility of growing everyone.This experience was one of the most influential leadership lessons I have come crossways till now. I am definite that I allow have a clear picture in mind when I embark on future leadership roles.Before pursuing my degree at Cass, I had the opportunity to look around my brothers nascent IT firm which is primarily focused on web-based services and providing internet marketing solutions. Though a well rounded firm, I sensed a lack of strong innovation and new products. This might jeopardize the company in the long run. Ideally, after completing my graduate studies, I am neat to join him and oversee the launch of new products, specifically, something along the lines of an automatic website builder. Furthermore, I am also keen to move the c ompanys operations to different cities in the nation where there is an opportunity of further growth. Taking charge of being the Product Head and institute such flips depart require strong leadership skills. progressive Leadership Launching a technologically advanced product in my organization lead require me to adopt innovative leadership characteristics and work seamlessly across different sets of people having varied skills.A good innovation leader is characterized by the ability to excel ontwoconflicting skills creativity and discipline. creativeness involves skills such as idea generation and conceptualization while discipline involves the skill to implement and launch. A successful leader should measure the weight of two and take actions accordingly (Roland Bel, 2010). Furthermore, Innovative leaders are characterized by the following attributes (Jean-Philippe Deschamps, 2008)Mix of Emotion and RealismThe Acceptance of Uncertainty, Risks, and FailuresHigh Degree of Passi onThe Willingness to Proactively look for for External Technologies and IdeasThe Courage to Stop Projects, Not Just to Start ThemTalent for Attracting Innovators and Building and Steering Winning Teams jibe to the author if an individual needs to stupefy an innovative change in the organization, he or she should possess at least some of the qualities listed above so that they are successful in livery new products or services in the market.Adaptive Leadership and change Coming back to my tenure at IBM, what my colleague did differently with others in the team was that he forced us to think differently than other teams, livery out the best in everyone. Each one of us was flexible in taking any type of task, further increasing the teams flexibility and productivity. According to Ronald A.Heifetz and Donald L.Laurie (1997, p132-141) Organizations today require adaptive leadership where challenges reside not in the executive director suite but in the collective intelligence of emplo yees at all levels. This is where the success of many future ideas and entrepreneurial ventures will lie. I believe bringing in such a change will be one of my biggest challenge once I take the leadership role. Moreover, Adaptive change will require people to work in new ways, new relationships and take on new roles (Ronald A.Heifetz and Donald L.Laurie, 1997).I intend to carry out such changes through the implementation of different project management techniques such as Lean and Agile (Schwaber, 2004). These techniques have been successful in recent years as they are quite adaptive in nature. These techniques forces employees to adapt quickly, learn new things constantly and learn from their mistakes. In Particular, these techniques are found to be useful in major tech companies and technologically driven products and hence will suit the company style. I have already had experience with such techniques at IBM and hence I will be able to use my knowledge and skills to implement it within my future organization.A lot of companies such as IBM or Google make work shift of employees their top priority. They continuously invest in employee transformation and hence are able to meet the challenges of the changing environment. When I was working in IBM, I remember going through multiple trainings and workshops and these trainings did not just include technical trainings. Trainings such as communicating effectively, leading in teams, how to conduct meetings etc were equally important. According to Mike Pedler et al(1989,pp1-8) an organization which facilitates the learning of all its members and continuously transform itself is a learning company . My future goal will also be to change my organization into a learning company through employee development programs and knowledge management systems (Pedler et al, 1989) as currently there is lack of such learning.My skill warning The skills model provides a good overview of the skills which are necessary for an effective leader (M.D. Mumford et al, 2000). Appendix 1 lists my score in the three components which are described in the modelTechnical skills The high score in this regard can be attributed to my experience in software engineering and working on a complex product while I was working in IBM. My daily tasks almost always included problem-solving and analyzing product requirements in detail. According to Mumford et.al (2000, p.24) the experiences required in the course of leaders careers influence their knowledge and skills to solve complex problems. My background and experience will help me tackle problems during the development stage of the product.Human skill Throughout my professional experience I worked with different sets of people with varied skills and experience. The entire project in IBM consisted of over a hundred people in India, and the product had multiple features that required expertise and collaboration from multiple teams. This meant communicating with various team leads and delegating responsibilities. Though I had quite a sufficient experience working in teams, there is still development which needs to be done in this regard. For e.g. Participating in Toastmasters club at CASS will improve my communication and leadership skills. The experience of working with people from diff cultures and backgrounds in CASS will further improve my people skills. abstract skill Since my duties at IBM were basically technical I was largely uninvolved in the strategic decision-making process. My low score represents my lack of experience in this skill and needs the most development. Conceptual skills require working at an organization level and working with ideas (Peter G.Northouse, 2013). I plan to intern at a start-up company so that I am able to have experience at an organizational level. It will give me an overview of the challenges which are faced by new organizations when launching new products or services. Furthermore, not to forget the mentoring I will have f rom my brother who has been heading the company for a couple of years now. Learning form him will improve my understandings and will help me tackle issues at a higher level.Additionally, I will have to broaden my knowledge base further and enhance my entrepreneurial skills to be successful in my futures goals. Though Leadership theory and practice can greatly improve a persons leadership skills a competent backing leader is one who possesses a clear vision for his or her company, is keenly aware of emerging trends and possesses the ability to capitalize on them.ReferencesBel, Roland. 2010, Leadership and Innovation Learning from the Best, Wiley Periodicals-Global business and Organizational Excellence, pp 47-58Deschamps, J.

Importance Of The Nile River For Egypt

Importance Of The Nile River For EgyptWater contamination is the presence of any substances in water which push aside be catastrophic for plants and animals that hot in water or people who use it. In other word it is the change in the chemical or physical properties of the water and this change can lead to cause damage and health hazards to animals and plants that live inside it or organisms that use it. (1)Importance of the Nile River for EgyptThe Nile River is the primary water resource in Egypt, where it represents more than 95% of the total water resources in Egypt and it is the lifeline for Egypt and there are many reasons for its importance which areEgyptians depends on it to acquire fresh water to use it for mingled purposes such as drinking, cooking, cleaning and other household uses.Use it for gardening where fertile land formed around the Nile River and they irrigated by Nile River.The Nile River is an important source of seek.It is use in water transportation becaus e it passes from south to north Egypt.Industry in Egypt depends a lot on the waters of the Nile River.Recently after the construction of the high-pitched Dam became the Nile River is an important source for generating electricity to Egypt. (2)(1) http//www.smokefreecolorado.com/cause-for-water- contaminations/(2) http//answers.yahoo.com/question/index?qid=20090216123423AALSyKICauses of pollutionThere are many sources of water pollution in Nile River.Industry wastewaterIndustry is an important user of water. In analogous time is an important producer of pollution. Water is very important in manufacture. Water demand for industry was 3.6 Billion Cubic Meters BCM/ social class in 2000. And they expect to be 5.5 Billion Cubic Meters BCM/year in 2017. So, when industry increases, the water demands increase.(1)Municipal WastewaterIn the city, the water which used by people going down through various treatment processes to make it healthy as possible before retire it back to environme nt. Treating water is help to minimize the negative effects of wastewater on the environment. However, some poor cities along Nile River cannot use treatment facilities which are valuable for them. The only way they can use it is dumped in the river without treated. (2)Statistics show that, whole g all overnments generate 3.5 Billion Cubic Meters BCM/year of wastewater. Of these wastewater 1.6 Billion Cubic Meters BCM/year receives treatment. In 2017, 1.7 Billion Cubic Meters BCM/year will receive treatment. Although the capacity will increase scarcely it will not be able to covers all wastewater. As it is show in table (1) the number of people serves increase and number of people not served increase because increasing in community. (3)http//www.irgltd.com/Resources/Publications/ANE/2002-09%20Survey%20of%20Nile%20System%20Pollution%20Sources-Egypt.pdfhttp//sitemaker.umich.edu/sec004_gp5/pollutionhttp//www.irgltd.com/Resources/Publications/ANE/2002-09%20Survey%20of%20Nile%20Syste m%20Pollution%20Sources-Egypt.pdfSo, it will not be able to decline the amount of wastewater that is not receiving treatment. (1)Agriculture WastewaterAgriculture is larger consumer of water. And it is in same time contributed in water pollution. Runoff from the agricultural sector frequently contains pollutants that may have an adverse effect on the river. Pollutants such as salts, nutrients want phosphorus and nitrogen, and pesticide residue can be found in this runoff. Agricultural runoff often is a non-point pollutant, in that it can come from anywhere in a region, and not from a specific drain. This can make it difficult to There are also problems associated with agricultural runoff seeping into the groundwater as well. (2) result of populationThere are many effect of Nile river pollution. Some of these effects areThe presence of oil on the surface of the river works as a buffer between the sun and the plants. This leads to death of seek and Lack of food for humans. In additi on, that will decrease the number of fishermen Many fishermen have either leftfield their jobs altogether or migrated, el-Fikky said.

Saed said he usually catches 2kg of fish a day that equal to US$165 a month, but over the past few months he has had an additional headache his net needs replacing not every month as in the past but every few days, costing him up to $144 a month.The Nile river is source for drinking but because it polluted by human that could cause a harmful effect on human and cause a dangerous diseases. Not only for people whose drink from it but also for people who eat fish or plant from it. (1)http//www.irinnews.org/Report/87416/EGYPT-River-pollution-hits-Nile-fishermenAbstractWater pollution is a serious problem for the all world. And it is considered to be one of the most harmful problems change Egypt. The pollution of Nile River is increase especial in the past few decades.Although the Egyptians love the Nile River a lot and it is important for them, not only in economic damage but it has a significant meaning for them. But this did not protect it from pollution.In this report I will explain the meaning of water pollution. Then, I will take about the important of Nile River. After that, I will talk about causes of Nile River pollution which are industry wastewater, municipal wastewater and agriculture wastewater. Final, I will take about effect of Nile River pollution.IntroductionWater covers more than two thirds of the Earths surface and the rest taken up by land. When the population are increase, the demand for water sources are increase. One of these fresh water resources is Nile River. As we know water is essential for life. No organism can live without it. Water pollution is problem effect human, animals and plants. And it caused by different resource. In these report I will try to find the main causes of water pollution in Nile River and the effect of that pollution.SummaryIn the summary, as you see all water pollution in Nile rive and in any place in the world created by human and then he try again to solve it what he already create. I advice all people to maintain the environment. And entertain the water clean.ConclusionIn conclusion, I learn from these report that human create problem. Then, it is adversely affecting our life. For that, I think that the maintain of the environment is a joint operation between all members of the community.UAE UniversityFaculty of ScienceDepartment of BiologyPrinciples of Environmental ScienceDone by Shaikha Mohammed.ID 201003128.Instructor Dr. Tarek Youssef.

Racism in America :: essays papers

Racism in America The Construction of an Institution For hundreds of years, it has been truth that the unravels were biologicly dissimilar. The differences that separated society were base on scientifically based genetic differences that gave reason for the separation of races. However based on recent findings, it is known that this is not the case. In 1974 Richard Lewontin dispelled this myth with a study he did that prove that there are no genetic differences amid races. In fact he discovered if anything, there were more differences within the races then between the different races. Why then, do we still have use for different races? Why is racism still rampant in American society? The reason is that although race is not founded through science, this institution of American society is merely an obsolete combination of historical, social, and cultural construction. Historically our physical differences supplied reason to separate into races. In do ing this we wait the emergence of races. Europeans marked individuals that looked different from them and used this difference as a justification for their reasoning that these individuals were inferior to them. To support their claims, there was scientific research through to explain our differences. These differences were said to be biological. As early as the 1800s scientists purported these ideas to be true. One doctor believed that blacks suffered from a form of leprosy. Because science is said to be so exact and indisputable, Americans held these theories to be truth and used them to construct the different classifications of race. These biological findings provided the basis for the most corrupt institution in America racism. Through the classifying of population of color as inferior due to genetic reasoning, provided whites with an excuse to dominate. This social issue divided the country and served as a weapon to keep commonwealth of color in the minority and deni ed them of any economic or educational power that was necessary to survive in America. This social phenomenon further abused the biological differences to further oppress people of color. Race provided the perfect method of domination in America. To the dismay of racists around the country, a scientist decided to reevaluate the genetic differences between the races, that had been so cleverly constructed.
