Analysis Paper - Essay Example These transitions are highly stressful and college years have been known to be the most stressful times in life. This stress is caused by academic, personal and social challenges. Students are expected to perform demanding tasks while adjusting to their new environment under minimal supervision. This stress has a negative impact on them which results to smoking, alcohol abuse and eating disorders. Research has shown that stress experienced in this period decreases mental health which leads to depression and low self esteem. Stress has become a major concern for the millennial student population and there is need to analyze this topic in relation to stress tolerance. It is important to note that people react differently to similar stressors. This paper agrees with this article and shall go into detail to explain why. College years are regarded as being the most stressful time in one’s life. The millennial age bracket has distinct features that entail the way they handle stresso rs. The sole purpose of the research discussed in the text was to make out lifestyle habits and coping approaches that are related to varying levels of stress tolerance among the millennial students in their college years. The methodology applied in this research was a random questionnaire that was conducted in a randomly selected college. The questionnaire included coping strategies, symptoms and checklists for stressors. The subjects were grouped into high stress tolerance and low stress tolerance and the STRs (Stress Tolerance Ratios) determined (Hellen et al. 362). From the results obtained, ten coping factors were connected to high stress tolerance, nine were put one in a situation of low stress tolerance while one was a protective factor. According to the findings of the study, it is clear that the lifestyle habits and coping mechanisms presently being used are ineffective. These strategies also put millennial students in a position of low stress tolerance. This article seeks to address the problem of stress experienced by millennial college students during the transition period. The study also identifies the strategies that are linked to low or high stress tolerance. This population is characterized by unique features thereby their stressors are also distinctive (Hellen et al. 365); thus the need for the application of non conventional coping methods. If some coping strategies are efficient, it is possible for students to develop their stress tolerance, not taking action when the stress is out of hand. This article mainly targets the college administration, teachers and general staff. It is an informative article that has information on the causes and symptoms of stress in the learning environment. It can be used as framework for formulating stress coping strategies. The article is also valuable to parents since it helps them to understand behavior of the millennial students and give them the necessary support throughout this period. The subjects themse lves are educated on how to cope with stress and develop high stress tolerance to the highly stressful college period. This is as clearly indicated in the essay. ‘Stress Tolerance: New Challenges for Millennial College Students’ is an effective essay because it is has been written is a clear language, has used supportive evidence to build on its argument and used transition statements to enhance flow. The writer has used simple and clear statements that are easy to read and understand. The essay has clearly

The Value of Hennes & Mauritz Essay Example for Free

The Value of Hennes Mauritz Essay In the last year the world economic recovery has come a long way. The Swedish economy has been at the forefront of that recovery and has showed impressive GDP growth. With still a lot of economic stress worldwide, mostly concerning national debt, it is still unclear if we have seen all that the financial crises, culminated in the late 2008, has to offer. With this said, the last years high volatility in the financial markets, will have an impact on this thesis. In almost all forms of valuation, some input will always be historical, why the past extreme years will affect the valuation. The models that are being used are the Dividend Discount Model and Free Cash Flow To Firm. Both of these valuation method has a couple of governing assumptions; mainly the assumptions of no transaction cost, perfect information and perfect competition. In reality none of these assumptions is hundred percent accurate. There exist transaction costs, everybody has not the same level of information, and there is evidence of not perfect competition. Nonetheless investors use these models and assume that the assumptions hold good enough for their purposes. This is Hennes Mauritz HM (Hennes Mauritz) is a Swedish clothing company headquartered in Stockholm, Sweden. The business idea is; Fashion and Quality at the best Price. With 87 000 employers in forty countries and with revenues over 126 000 000 000 SEK it is the third largest chain store in the world. HM has over 2200 stores on four continents and their goal is to increase the number of stores with 10-15% annually and keep a high profitability and increase sales in comparable numbers. In 2010 HM opened 218 new stores and in 2011 250 new stores are planned to open1. HM is a family business founded in Và ¤sterà ¥s, Sweden, 1947 by Erling Persson2. Today Erling Persson’s son, Stefan Persson, is chairman of the board and Stefan Persson’s son, Karl-Johan Persson is chief executive. As a token of the success of HM Stefan Persson is now the second richest man in Sweden and thirteenth richest in the world, with 159 000 000 000 SEK in wealth3. In 2008 Financial Times announced HM as the most valuable brand in Europe4. In the upcoming years HM is planning to expand in Kina, USA and Great Britain. Even though they are first and foremost a clothing company HM is also active in home equipment, shoes and cosmetics5 HM rents all their storage space or set up stores as franchise. In UK, Germany, Sweden, Norway, The Netherlands, Finland, Denmark and Austria online shopping is available. All expansion and growth is financed by equity6. The Purpose The purpose of this thesis is to establish the value of Hennes Mauritz. The valuation will eventuate in the conclusion if the stock is under- or overvalued. To arrive at this conclusion we will use two valuation methods; Dividend Discount Model and The Free Cash Flow to Firm valuation method. 2. Theoretical Framework 2.1. The concepts of Value and Discounted Cash Flow valuation Before we are getting into the theoretical aspects of our two valuation models, we are going to give a brief explanation about the concept of value for shareholders and discounted cash flow valuation. The most basic question one can ask about a valuation is: What is Value? When talking about a company’s performance there tends to be a focus on earnings and revenues. But must two companies that have the exact same earnings and revenues, over time, be worth equally? The answer to this question is no and the reason is that the cash flow may differ. Cash flow is the difference between earnings and invested capital. Even if earnings and revenues are the same, one of the companies may have to invest a lot more capital to gain the same earnings and revenues. This leads to a difference in cash flows between the companies. Value for shareholders is created when the company generates cash flows at rates of return higher than the cost of capital. When this condition is fulfilled a faster growth rate will create even more value. If the return on capital equals the cost of capital it doesn’t matter how fast the company grow, no value will be created. The conclusion is that managers’ main focus should be on improving cash flows because that is what creates value for shareholders. â€Å"Any action that doesn’t increase cash flows doesn’t create value.† 7 In this thesis we are going to use the Discounted Cash Flow (DCF) valuation in order to calculate the value of a company. DCF is built upon the concept that money has a time value. This means that the longer in the future one will receive a fixed amount of money the less it is worth. The reason is that if one receives the fixed amount immediately one can invest it and earn interest. In the DCF valuation the first step is to estimate all future cash flows. The second step is that the cash flows have to be adjusted for the time value. Since the purpose is to find out how much the company is worth today, one has to discount the cash flow to its present value. The discount rate will reflect the riskiness of the estimated cash flows. The riskier the estimation is the higher discount rate should be used. 2.2 Discounted Dividend Model The first method we are going to examine is the Discounted Dividend Model (DDM). The DDM uses earnings per share, discounted by the Cost of Equity to arrive at a value per share. The general version of the DDM8 looks like this; Where; E(DPSt)= Estimated dividend per share at time t ke = the Cost of Equity t = time in years To this general composition there exist several extensions. Some of these extensions are going to be examined below. 2.2.1 One-stage/ Gordon Growth Model An extension to the formula above is the Gordon Growth Model: Ë ¢IË ¬Ã‹ ¯Ã‹ ¥ JË ¦ ËŸË ®JIË « The principle is to take the expected dividend for the next year and discount it with the cost of equity minus the growth rate in dividends. An obvious restriction for the model is that the growth rate can never exceed the cost of capital, since the stock price in that case becomes negative9. Due to the simplicity with a constant growth rate it is far from possible to apply this model on every firm. The model is best suited for firms growing at a rate equal to, or lowers than, the nominal growth in the economy and which have well established dividend payout policies that they intend to continue into the future10. Since this model only contains one single growth rate, it is called one-stage model. The assumption is that the firm continues to grow at the same rate to infinity. However, it is not likely that a firm can maintain a high growth forever. Sooner or later the growth rate will decrease and a more stable and lower growth rate will emerge. This limitation takes us to the next model, the Two-Stage model, which is an extension to the One-stage model.

Can I know what another person is thinking or feeling? If so, how? :: essays papers

Can I know what another person is thinking or feeling? If so, how? The problem of Other Minds is a true philosophical enigma. It is apt to strike children with no philosophical education whatsoever, yet remains intractable to many academics. Broadly speaking, the problem can be divided into three questions. Firstly, how do I come to believe that there are minds in the world other than my own? Secondly, how can I justify my belief that there are minds in the world other than my own? Thirdly, what can I state about the mental states of minds other than my own?. The question we are dealing with here falls largely into the third category, although of course issues relating to the other two will also be involved. Firstly, it is imperative to assert that, in looking for 'knowledge', we are not aiming for logical certainties - we are not aiming to show that any propositions about other minds can be demonstrated with absolute certainty equivalent to that of mathematical truths. Philosophy ever since Descartes has tended to be defined by scepticism: either it aims to produce sceptical theories or it aims to refute them. And sceptics tend towards extremity in their doubts. It must be stated here and now that there are not, and never can be, any theories that prove demonstratively that other minds exist, or that I know others' mental states. This is not what should be aimed at in attempting to solve the problem. As Austin puts it "To suppose that the question 'How do I know that Tom is angry?' is meant to mean 'How do I introspect Tom's feelings?' is simply barking up the wrong gum-tree." Most philosophers agree that their theories only bestow a greater or lesser amount of probability onto statements about other minds (although there are exceptions, e.g. Peter Strawson's attempt to argue transcendentally for the existence of other minds through our own self-consciousness). There have been a number of different attempts to do this. J.S. Mill, who produced the first known formulation of the Other Minds problem, used the so-called 'Argument from Analogy' both to explain how we come to believe in other minds and to justify this belief. Briefly, the argument holds that I am directly aware of mental states in myself, and I am aware of the behaviour of mine that results from and is caused by these mental states. As I can observe similar physical behaviour in others, I draw the analogy that it is caused by the same (or at least similar) mental states to my own.

The Effects of the Renaissance Essay -- European Renaissance Essays

The Effects of the Renaissance When the Renaissance crept into the world?s social senses people were moved. However, when the Renaissance began to affect the literature of the sixteenth century, the world was changed forever. The Renaissance, meaning a ?re-birth,? was a time of many changes. These changes wrought pandemonium among the civilized people of earth. There was a recovery and discovery of medieval texts in which scholars were deeply impressed by. Those in love with the arts and literature now had more choices to view and read. There was an outpour of those individuals attempting to create paintings that exemplified the feelings that saturated the minds of the brilliant scholars. Most importantly, however, was the huge change of the role of the church in everything. Martin Luther nailed up his ?95 Thesis? and thus began the Reformation of the Catholic Church. With this came a rushing tide of secularization in Europe. This, of course, blew over into literature and the arts. The Faerie Queen is one epic that included the ideals and morals that the excom...

The Outsiders Literature Response

The Outsiders by S. E. Hinton original copyright 1967 The protagonists in the book are the Greasers and the antagonists are the Socs. The main characters are Darry, Soda, Dally, Bob, Ponyboy, and Johnny. Darry is tall, muscular, smart and very strict towards Ponyboy. Darry yells at Ponyboy and always seems to expect better from Ponyboy. For example, Darry yells at Ponyboy on page 49, â€Å"Where the heck have you been? Do you know what time it is? He was madder than I had seen him in along time. I shook my head wordlessly. † Soda is always optimistic and lighthearted. One of the only things that bring Soda down is the fact that he is a school dropout who works at a gas station. Soda tries to support Pony when Darry is mad at him but tries not to take sides. Soda explains how he doesn’t like when Darry and Pony fight when he says, â€Å"It’s just†¦I can’t stand to hear y’all fight. Sometimes I have to get out or†¦it’s like I’m the middleman in a tug o’ war and I’m being split in half (page 175). † Dally’s actions, like robbing a store, makes him seem like he is mean and tough but actually he is a very caring person on the inside. An example is when Dally enters the burning church to save Pony and says, â€Å"For Pete’s sake, get outa there! That roof is going to cave in any minute. † Bob is rich and undisciplined by his parents who make him feel like he has the power to do anything he pleases. Bob is intimidating to the Greasers like Johnny and Pony because he has the ability to do almost anything he wants. An example of Bob picking on Pony and Johnny is when he orders a Soc to give Ponyboy a bath in the park fountain by drowning him as a sort of cruel joke (page 55). Ponyboy is more emotional than all of the Greasers and takes feelings in to deeper consideration. Pony is not as violent as other Greasers and is very friendly. An example is when Pony went to the drive-in movie; he easily became friends with the popular Soc cheerleader, Cherry. This shows a lot about his personality because most Socs wouldn’t even want to talk to a Greaser. Johnny is shy, defenseless, and small for his age. He is harshly bullied by the Socs and by his parents. For instance on page 33, Pony describes how Johnny was mugged by the Socs, â€Å"They caught him and one of them had a lot of rings on his hand—that’s why they had cut Johnny up so adly. It wasn’t just that they had beaten him half to death—he could take that. They had scared him. † The setting takes place in a rough town somewhere in the U. S. around the 1960’s. The town is infested with crimes and delinquents. It’s socially divided into two parts, the east where the low-class Greasers live, and the west where the rich Socs live. The Greasers and the Socs are strong rivals who always take the opportunity to fight each other. Therefore, it makes walking down the street a dangerous task with the possibility of being mugged. An example of the environment of this town is in the scene where Ponyboy is mugged by the Socs while he was walking himself home from the movie theater. It’s dangerous for people like Pony to even walk on the city streets without risking being cut up by a Soc. The story starts out with Pony being jumped by the Socs until Pony’s gang rescues him. The next night Pony, Dally, and Johnny go to a drive-in movie and meet two girl Socs, Cherry and Marcia. By the end of the night Pony and Cherry become good friends. Before returning home Pony and Johnny go to a vacant lot to talk. They both fell asleep in the lot and woke up around 2 A. M. Pony goes back home only to find Darry as mad as ever. Darry lectures Pony about his curfew and ends up hitting him. Ponyboy becomes overwhelmed and decides to run away with Johnny. Pony and Johnny walk to the park until they notice the Socs approaching them. Bob is mad that the Cherry and Marcia were interacting with the Greasers; so he decides to mug both Johnny and Pony. The Socs begin to drown Ponyboy in the fountain until Johnny stabs Bob. The Socs then began to flee. Ponyboy and Johnny need help from Dally to run away while avoiding being arrested for murder. Dally tells them how to escape to Windrixville and survive behind an old church. Dally checks up on them in a week and tells Johnny that Cherry had testified that the murder had just been an act of self-defense. Johnny decides to turn himself in; so Dally drives them back until they notice that the church was on fire. Pony and Johnny run inside and rescue the kids that are trapped. Pony barely escapes, but Johnny was more severely hurt and ends up dying in the hospital. Dally becomes depressed because of all the misfortunes so, he commits an armed robbery at a grocery store. The police chase Dally to a lot where they kill him for armed robbery. Pony becomes traumatized because of all of the drastic events and deaths of his close friends. The main conflict in the story is when both Pony and Johnny are jumped at the park by the Socs. The Socs start to drown Pony in the fountain until Johnny stabs Bob. The Socs immediately fled to their cars and drove away. This conflict type person vs. person, in this case it would be the Socs (particularly Bob) vs. Johnny and Ponyboy. This conflict was external because it was made up actions. A minor conflict would be when Ponyboy is in great sorrow because of Johnny’s recent death. Pony can’t get over the fact that one of his closest friends, who actually deeply cared about him, died just overnight. This conflict type is a person vs. self; this is internal because it involves Pony’s feelings. An example of a person vs. nature conflict is when the church burns down. Johnny and Pony frantically enter the burning church to save the children form the fire. This is a person vs. nature conflict because the fire, which is part of nature, burns down the church which affects Ponyboy, Johnny, and the children who are trapped inside. The story is told for Ponyboy Curtis’s point of view. The author may have chosen this point of view because it would be easier to understand the story through a fourteen year old boy’s perspective and it may also make the book more appealing to teenagers. This point of view is critical to the story because it’s from the perspective of an outsider who thinks life isn’t fair to them. This story would have been altered if it were from the point of view of a Soc because the Socs feel as if they can do what ever they want and get what ever they want. If that had happened then the story would have been talking about how bad the Greasers were and how fabulous the Socs were. The mood in this story is bitter and unruly, especially for the Greasers because of their low status in life. The atmosphere is violent because of gang fights and various crimes. The story’s mood and atmosphere change when Pony and Johnny go to the country. The mood changes from harsh to quiet and relaxed because of the smaller population in the country. Here is an example of a mood and atmosphere change in the country (pg 63), â€Å"We lay in the tall weeds and damp grass, breathing heavily. The dawn was coming. It was lightening the sky in the east and a ray of gold touched the hills. The clouds were pink and meadow larks were singing. † The underlying message and theme of the story is the line, â€Å"Stay gold. † Stay gold means that you should remain young and wondrous because nothing stays gold forever. Johnny’s letter to Ponyboy explains that you are gold when you are a kid. Johnny says that the way Pony like sunsets is gold and to remain gold forever.

Macroeconomics essays

Macroeconomics essays All those who live in the United States are accustomed to private property. Everyday situation sometimes lead to what life would be like without it. One can see what the effects are to living in a private society and realize how efficiency and justice are raised to an overall level. This takes place within an apartment building in Washington DC, however many apartments throughout the United States would off the same aspects. Upon living in the apartments, tenants are charged a monthly rent as well as an additional bill for utilities, which includes gas, water, fuel, oil, and electricity. The apartments are considered "master metered", which means those living in the apartments are allowed to use as much electricity, water and gas as they want. At the end of the month the utilities are added up and divided amongst the number of tenants and then billed appropriately. However, the idea of "master metered" brings up the problem of some getting a free ride off those who conserve. For example, take two people who live in the same apartment complex. One of the tenants is very aware of conserving energy. She always turns off the lights when she's out of the room, turns the air up a little in the summer and the heat down in the winter. She basically lives her life being a little uncomfortable for the sake of saving everyone in her building a little money. On the other hand, her neighbor does just the opposite. He never turns out the lights, keeps his apartment ice cold in the summer and nice and toasty in the winter. He even decides against turning his air off when leaves for the weekend, figuring he'll come home to a hot apartment. He feels he is just paying an average of everyone's consumption so why should he not be comfortable? So between the neighbors, the bill at the end of the month remains the same because one gives a little wh ...

Chills operates under a parent company which is Bringers who also runs and operates On the Border Mexican Grill and Magicians Little Italy. (Salad, 2009). This strength is Important because with all three restaurants each is getting exposure through advertisement . Gift cards to the restaurants identify that the customer can use the card at any of the three restaurants mentioned, which heightens curiosity and the opportunity for new customers.

I carry out the simple goals of providing excellent customer service which ultimately boost sales because guests are more likely to return. How I contribute to the companys business strategy may seem very small but its also the most important.

Principal Quantum Number Definition

Principal Quantum Number Definition The principal quantum number is the  quantum number denoted by n and which indirectly describes the size of the electron orbital.  It is always assigned an integer value (e.g., n 1, 2, 3...), but its value may never be 0.  An orbital for which n 2 is larger, for example, than an orbital for which n 1. Energy must be absorbed in order for an electron to be excited from an orbital near the nucleus (n 1) to get to an orbital further from the nucleus (n 2). The principal quantum number is cited first in the set of four quantum numbers associated with an electron. The principal quantum number  has the greatest effect on the energy of the electron. It was first designed to distinguish between different energy levels in the Bohr model of the atom  but remains applicable to the modern atomic orbital theory. Source Andrew, A. V. (2006). 2.

The effects of the 2008 financial crisis on the investment in the Gulf Research Paper - 2

The effects of the 2008 financial crisis on the investment in the Gulf area and Qatar(different copy) - Research Paper Example The initial impact of the financial crisis was felt partly in some Arab states depending on their participation in the international markets (Qatar 6). Impact on Finance and Economy The 2008 global economic crisis affected the financial markets of countries in the Gulf region. In many states, the stock exchange index declined by nearly 62% in 2008. By 2009, the projected GDP growth rates had fallen from 3.5% to 0.5% (Rocha & Subika 71). In addition, the economic growth decreased by more than 3% in the same year. With the exception of Qatar and Yemen, most states in the gulf area have projected lower GDP growth rates. The cornerstone of Qatar’s’ economy is petroleum. Most of the government revenue, export earnings, and GDP are derived from oil reserves and gas exports. Qatar is the third producer and exporter of oil in the world making it the richest country in the world (Rocha & Subika 71). Effects on banking The banking sector in Qatar escaped the impact of the financi al crisis. Most banks all over the world lost their role as creditors and financiers because of the crisis. Banks in Qatar posted big profits in the Gulf Cooperation Council markets in 2009 despite the financial crisis (Sheng 45). ... Qatar’s Central Bank has taken measures particularly in the real estate sector. Qatari Central Bank issues instructions on buying of shares and financing of real estate projects. Decisions of lowering interest rates, enhancing the compulsory reserve ratios and other key issues in management of banks have been properly addressed in accordance with market mechanism. Qatar’s monetary policy is risk free due to the sound policies implemented to attract foreign markets (Rocha & Subika 65). Economic growth and Employment Before the financial crisis, the gulf region had numerous job opportunities in the world. The financial crisis led to a decline in job opportunities in the gulf area. Total employment decreased greatly. Research shows that the percentage of women seeking employment also increased in the region due to the effects of the financial crisis that caused slow economic growth, inflation, and economic meltdown. Agriculture and manufacturing that were once the main sou rces of employment are now less competitive because of the export of goods to the global markets. It is difficult for women and girls to find jobs that are considered gender appropriate (Sheng 34). The financial crisis led to a decline in labour productivity in the non-oil sectors in the Gulf region and especially in Qatar. An expectation of future pick up in labour has led to hoarding resulting and reduced productivity of labor. Recent conducted analysis shows that the working age and gender have a great impact on the labour force. The global crisis has led to a reduction in migrant remittances. Migrants are important because they contribute to the labor force in the

Reflective Case Study on the Assessment and Evaluation of Secondary Essay

Reflective Case Study on the Assessment and Evaluation of Secondary Mathematics - Essay Example An evaluation refers to an intermittent process of gathering data and then analyzing it in such a way that the resulting information can be used to determine whether an individual is effectively carrying out planned objectives. Through evaluation, we will be able to anticipate results of a student's progress. On the other hand, assessment is the process of detailing knowledge, skills, attitudes and beliefs which, in turn, is often used in the educational context. I may consider that both of these techniques are the first steps in getting your child the assistance he needs to learn and develop in school. In accordance to this, a series of educational assessments carried out on children attending schools in England, Wales and Northern Ireland that follows the National Curriculum was made, called as National Curriculum Assessments. The exam-based assessments (National Curriculum Tests) are often referred to as SATs (Standard, or Statutory, Assessment Tests), which was their title when they were being developed in the 1990s. One of the subjects that were given importance is the secondary mathematics. I personally believe that there has never been a greater need to be mathematically literate but for those who comprehend mathematics, there are important enhanced opportunities and options that will open doors to dynamic futures. In the National Curriculum, schools are ensure... It is a flexible framework given to teachers by Government, so that all school children are taught in a way that is balanced and manageable, but stretching enough to challenge them and meet their diverse needs. The National Curriculum is prearranged into blocks of years called 'key stages'. I am about to examine key stage 3 and key stage 4 performance in Mathematics. Here is an example individual pupil profile of a student in key stage 3. *Important Note: A pupil's score is only an estimate of true ability as performance on any one occasion can be affected by a number of factors such as mood, illness, external distractions etc. Here are the results of last year's (2005) National Curriculum Test Scores in Mathematics. These tables show the percentage of year 9 pupils achieving each level nationally in 2005 Assessment Data The following can are some available assessment tests that can be used. The Basic Yellis Test, which has been in use since 1992, as a measure of developed abilities providing a fair baseline from which GCSE predictions and value-added scores can be generated, also helps in assessing the pupil's performance with regards to the curriculum. Their compulsory math section has been designed with an emphasis on measuring fluency and speed as well as numerical ability. One of their most efficient ways of collecting mathematical information is the use of constructed answers rather than just multiple choice questions. According to them, the Math score is an excellent predictor of later academic achievement.

Analysis of the costs and benefits of China`s economic reforms in last Essay

Analysis of the costs and benefits of China`s economic reforms in last decades - Essay Example The early reforms were more definite since they were responses to definite problems and crisis of that period. In the second phase, the reforms were adapted to new set of challenges and opportunities (Naughton, p.107). China has shown a remarkable economic progress after centuries of oppression by the Westerners. Recently the China Daily newspaper has conferred that the nation is an example to all nations who are struggling to stand on their own feet (Callick, 13). In 1991, General Secretary Jiang Zemin that temporary difficulties cannot prevent the Chinese from continuing to develop (Saich, 75). This paper is the best example of analysis of the pros and cons of China’s economic reforms in recent decades. In the early 1990s, China’s approach towards economy resembled any other transitional economies with emphasis on sustaining balanced and efficient financial policies. The principles objectives were to eradicate corruption, promote a developed market economy and maintain fair competition in the domestic market. China’s fiscal policies are mostly complex and have yield varying resulting in different phases of reform. The early reforms were more definite since they were responses to definite problems and crisis of that period. In the second phase, the reforms were adapted to new set of challenges and opportunities. China has shown a remarkable economic progress after centuries of oppression by the Westerners. Recently the China Daily newspaper has conferred that the nation is an example to all nations who are struggling to stand on their own feet. It has been rightly assumed that the conversion of China from state socialism to market economy has generated pervasive corruption. With constant changing of reforms, public official took the opportunity to fulfill their personal ambitions. The factors encouraging corruption became more apparent from the pre-reform era with officials submerged in informal relationships. Market reforms in China have paved the way for growing disparity among different sectors of the society. Since policies now are mostly market based, the former strong relationship between the Communist Party and the Labor has deteriorated. Chinese economy today focuses mainly on urban regions. The transformation phase of China can be educative but only from the perspective of the overall transition

Standardising HR practice in IT company Essay Example | Topics and Well Written Essays - 2500 words

Standardising HR practice in IT company - Essay Example However, the situation might be a little bit complicated when it comes to handling manpower in the multinational company, which has operations in all over the world with different cultures and values. Globalisation is a very important concept. Knowing it fully will pave way to understanding how entirely a multinational level company should operate. Clive (2001) defined multinational companies as those with strategies and ability to organise allowing them to become sensitive and responsive to variation in national environments worldwide. From this definition, it is clear that the complexity in handling multinational company is taken into consideration. Paralleling the culture and technological innovations of recent time has been the most important development of a global business.For instance, the fact that there are differences of culture and other environmental factors from one country to another is a very important issue that the human resource department should take into consideration as far as the operation of company is concerned on a global basis. In the early 1990s, the IT Company as a large multinational organisation with relatively powerful independence was structured around geographical areas. This lead to different Human Resource (HR) policies that existed between countries where IT Company existed and this resulted further to different HR practices in areas such as training, pay and flexitime. In the early 1990s due to emerging global and local competition, IT Company experienced economic trouble. With this, the organisation tried to change its business and organisational structure. The decision-making authority of local managers was reduced and responsibility transferred to Paris and to the US as regional headquarters where regional managers have the total control on decision making process. In addition to this, business units were instituted which the purpose

School and Communities Essay Example for Free

School and Communities Essay A school leader guides a student for such a brief moment, but is one of the connections that contribute to a student being successful and allowing for the student to transition easily in the learning environment? According to the recommended readings there is a correlation between the student’s home, community, and the school that facilitates the student’s transitions into and throughout the school system, leading to an environment that supports student success. There are several major transitions starting with kindergarten and progressing to the middle school level, and then onto high school. Each transitional time is critical and requires additional support to continue and to achieve academically. Based on my review of various articles, the following topics are promising directions that have emerged as areas that will make the connection powerful and successful. Family involvement during Kindergarten preparation is essential for young students to achieve to their potential. The importance of being prepared academically for school, and its implications for parents, has been the subject of extensive research and attention. One recent study suggests that fostering parent support and  parent learning about Kindergarten readiness can help ensure that children are adequately prepared to start school (Starkey Klein, 2000; Perroncel, 2000). In my readings it was suggested that a network of social connections that support children and families during the Kindergarten transition are needed, including interactions between teachers and children, children and peers, parents and teachers, and preschool teachers and Kindergarten teachers. While there is an increased amount of evidence about the elements that support Kindergarten readiness, there is also a need to better integrate the early childhood development literature to  fully understand the connections that make a difference and allow the student to be successful. For example, Fantuzzo et al. (2000) conducted a study to assess parent involvement for children in day care, Head Start, and Kindergarten. Studies such as this can begin to build understanding of how parent involvement changes from pre-school to Kindergarten. Future research can also build our understanding of the specific types of family and community connections that provide a strong support network for children, particularly those who come from disadvantaged backgrounds, as they prepare to enter Kindergarten. STUDENT TRANSITION THROUGH EDUCATION LEVELS 3 Despite the continued occurrence of the myth that family and community connections are primarily important at the elementary school level, researchers have begun exploring the effects of school, family, and community connections during transitions to middle and high school as well. Gutman and Midgley (2000) found that during the transition from the elementary level to the middle school level, both school factors and family factors were important to support academic achievement in African American students. Another study found that, contrary to popular belief, middle and high school students do want their parents to be involved, especially in terms of homework help and other home-based types of support and involvement (Catsambis Garland, 1997). This study found that parent involvement does not decline, as expected, but rather shifts as students move into middle and high school. Although they continued to be involved, parents reported increasing dissatisfaction with their role in relationship to the school, especially involving school policy (Catsambis Garland). These results confirm the importance of continued exploration of needs that students have during the transition to middle school and to high school, and roles that families play in supporting these transitions. The impact of school outreach is an important finding. School outreach and invitations to families and community members have a significant impact on the level and quality of family and community connections. In at least three studies, it has been found to have a greater impact than family characteristics on previous student academic achievement (Van Voorhis, 2000; Simon, 2000; Chrispeels Rivero, 2000). Simon found that when schools reach out, and families and community members feel that the school is extending invitations at a personal level, they respond with higher attendance at school-based activities and better quality of family involvement at home. The unique role that schools play in initiating and setting the tone for connections with families and the community cannot be denied. Researchers have also suggested that more research is needed regards to what motivates individual school staff members to reach out to parents and community and how  school staff can be further motivated and supported in building these relationships. STUDENT TRANSITION THROUGH EDUCATION LEVELS 4 There is a growing understanding of the role that relationships between staff in schools and community organizations play in the development of successful collaborations between school and communities. Jehlet al. (2001) suggests that there are â€Å"sticking points,† in organizational cultures and values that can hinder school-community connections. They suggest that these sticking points must be understood and addressed in order to build effective partnerships. These disconnects can be exacerbated by the lack of personal relationships that build trust and understanding between school and community staff (Center for Mental Health in Schools, 1999a). It is clear that family, school, and community connections can benefit children from before the time they enter Kindergarten until after they graduate from high school. Our charge in the educational field of study is to come together to address the issues highlighted in this synthesis paper and to clarify the concept and outcomes of family and community connections with schools. In doing so we will better understand these connections and create the knowledge needed to realize the potential of family, school, and community connections for student learning and student’s success.

Nutrition During Pregnancy | Annotated Bibliography

Nutrition During Pregnancy | Annotated Bibliography Geraldine O’Sullivan, et al (2009) did this study to investigate the effect of feeding during labour on obstetric and neonatal outcomes. Prospective randomized controlled trial was used as design in this study. Setting of this study was at Birth centre in London teaching hospital. 2426 nulliparous, non-diabetic women at term, with a singleton cephalic presenting fetus and in labour with a cervical dilatation of less than 6 cm. were participants. In this study they provide light diet or water during labour and they measure the outcome of spontaneous vaginal delivery rate. Other outcomes measured included during this duration of labour, was need for augmentation of labour, instrumental and caesarean delivery rates, incidence of vomiting, and neonatal outcome. Result was the spontaneous vaginal delivery rate was the same in both groups (44%; relative risk 0.99, 95% confidence interval 0.90 to 1.08). No clinically important differences were found during duration of labour (geomet ric mean: eating, 597 min v water, 612 min; ratio of geometric means 0.98, 95% confidence interval 0.93 to 1.03), the caesarean delivery rate (30% v 30%; relative risk 0.99, 0.87 to 1.12), or the incidence of vomiting (35% v 34%; relative risk 1.05, 0.9 to 1.2).Outcomes of neonatal were also similar Hazel M Inskip et al (2009) conducted this to examine the extent to which women planning a pregnancy completely with recommendations for nutrition and life style .Design was used for this study were prospective cohort study. Setting was at Southampton, United Kingdom. Participants are 445 non-pregnant women aged 20-34 recruited to the Southampton Women’s Survey through general practices, 238 of whom became pregnant within three months of being interviewed. Result was the 238 women who became pregnant within three months of the interview were only marginally more likely to completely with recommendations for those planning a pregnancy than those who did not become pregnant in this period. Among those who became pregnant, 2.9% were taking 400 ÃŽ ¼g or more of folic acid supplements a day and drinking four or few units of alcohol a week, compared with of those who did not become pregnant. 74% of those who became antenatal mothers were non-smokers compared with 69% of those who di d not become antenatal mother (P=0.08). Women in both groups were equally likely to consume five or more portions of fruit and vegetables per day (53% in each group, P=1.0), but only 57% of those who became antenatal mothers had taken any strenuous exercise in the past three months compared with 64% in those who did not become antenatal mothers (P=0.03).Concluded the study as only a small proportion of women planning a pregnancy follow the recommendations for nutritional diet and lifestyle. Greater publicity for the recommendations is also needed, but as many pregnancies are unplanned, improved nutritional diet and lifestyles of women of childbearing age is also required. Alison M. Stuebe,(2009) e tal did this study to identify modifiable risk factors for excessive gestational weight gain (GWG). Project Viva cohort study was used as a design. In this study they assessed associations of diet and physical activity with excessive GWG among 1388 women. Three hundred seventy-nine women (27%) were overweight (body mass index ≠¥ 26 kg/m2) and 703 (51%) experienced excessive GWG, according to Institute of Medicine guidelines. In multivariable logistic regression models, they found that intake of total energy (odds ratio [OR], 1.10; 95% confidence interval [CI], 1.00-1.22, per 500 kcal/d), dairy (OR, 1.08; 95% CI, 1.00-1.17, per serving per day), and fried foods (OR, 3.47; 95% CI, 0.91-13.24, per serving per day) were associated with excessive GWG. In first trimester vegetarian diet (OR, 0.46; 95% CI, 0.28-0.78) and mid pregnancy walking (OR, 0.92; 95% CI, 0.83-1.01, per 30 minutes per day) and vigorous physical activity (OR, 0.76; 95% CI, 0.60-0.97, per 30 minutes per day) were inversely associated with excessive GWG. Hannah Tait Neufeld et al. (2008) did this study to describe how aboriginal women in an urban setting perceive dietary treatment recommendations associated with gestational diabetes mellitus (GDM).Design used was Semi-structured explanatory model interviews explored Aboriginal womens illness experiences with GD. Twenty-nine self-declared Aboriginal women who had received a diagnosis of GDM were participated .Result was participants associated fear, anxiety, and frustration with GDM. Emotional reactions appeared alongside negative relationships with food and other prescribed in lifestyle treatments. Results suggested that the experience of living with GDM can be overwhelming, as suggested by some of the complex factors influencing womens perceptions and reported behaviors. Discussions indicated that many felt socially isolated and had a poor self-image and sense of failure resulting from ineffective management GDM of practices. Penelope McLernon et al (2008) did this study. In this study, one of the most prevalent complications of pregnancy is asthma which is associated with an increased incidence of intrauterine growth restriction. The mechanisms that affect fetal development in pregnancies complicated by asthma were not clearly defined. Dietary fatty acids (FA) especially polyunsaturated fatty acids (PUFA) are particularly important during pregnancy due to their role in fetal growth and other development. The current study was designed to characterize the fatty acid profile in pregnant women with asthma to determine whether asthma severity or reduced fetal growth were associated with an altered FA profile. Maternal dietary intake and plasma fatty acid profile were examined in mother with and without asthma at 18, 30 and 36 weeks of gestation and maternal fatty acids levels were related to measures of fetal growth using Doppler ultrasound and birth outcomes. This was used as a method for data collection. R esults of this was that pregnant women with moderate and severe asthma had increased circulating plasma fatty acid levels at 36 weeks gestation but reduced dietary intake of fats compared to those women with mild asthma and healthy pregnant controls. In addition, women with moderate and severe asthma had increased circulating levels at 36 weeks gestation which was associated with reduced fetal and neonatal head circumference. Ruth M. McManus, (2007) et al did this study to compare the associated costs of actual food choices versus the cost of a constructed recommended diet. In this study costs associated with nutritious foods may be a barrier to healthy dietary choices and of particular concern to pregnancies complicated by diabetes. Survey was conducted in a tertiary care diabetes and pregnancy clinic to compare the associated costs of actual food choices versus the cost of a constructed recommended diet. Method which used this study was women with types 1, 2 and gestational diabetes mellitus (GDM) completed 24-hour dietary recalls under the supervision of the research coordinator (Actual Diet). Recommended Diet for this population was constructed independent of responses of participants. Actual and Recommended Diets were standardized per 2000 kcal, priced and compared for content and cost of diet. Result was Seventy-five women participated: 27 with GDM, 29 with type 1 diabetes and 19 with type 2 diabete s. There were no significant cost differences between Recommended and Actual Diets .Food choices expressed per 2000 kcal: Recommended Diet $10.14 ±3.72; Actual Diet GDM: $11.30 ±3.88; Actual Diet of type 1 diabetes: $9.00 ±3.16; Actual Diet of type 2 diabetes: $10.24 ±3.92. Percentage of fiber intake was lower for Actual Diets than Recommended Diet for all, while percentage of protein intake was lower in Actual than Recommended Diet for women in type 1 diabetes.

Making Money When the Market is Mistaken! :: essays research papers

Making Money When the Market is Mistaken! Part 1.) I did my program review on a one-hour show I watched straight through. It was called, â€Å"Making Money when the Market is Mistaken.† The lead man basically running the show was Conrad De Aenlle. He is also a writer for the New York Times and is an expert on making money. The show was basically on Stocks and how J.P. Morgan runs their company. Now nobody has ever gone broke by thinking others where stupid. There are many managers that work for J.P. Morgan and many of them agree that there is good money to be made underestimating others ability to get the job done right. Now what does that mean? Sounds wrong to me, I was taught to never underestimate others. Now during the entire show they would focus in on this point and try to prove that J.P. Morgan could and would make me money off others mistakes. The funds in most companies are run according to principles of behavioral finance, which means they are run according to behavior repetition. They believe that people are illogical, yet predictable. Followers of this approach do not ignore the nuts and bolts of business - profits, sales, cash flow and so forth. Basically all the functions of the daily business, But they say that investors consistently have errors in evaluating such information, and that professional portfolio managers, wink, wink (J.P. Morgan) can profit from the ways that others make mistakes. Conrad would constantly remind the viewers that he was a part of J.P. Morgan and he was trying to make me money. "Traditional finance theory tells us markets are efficient and rational," said Silvio Tarca, one of the managers of the Morgan funds and one of two people interview live on the show. And basically she says that human behavior leads to irrational decisions and that J.P. Morgan makes a lot of money off of and so should you or me. People when wrapped up in the stock investment life, start to invest based on feelings and emotions instead of logically reasoning. She said J.P. Morgan is practicing sociology instead of just stock investments to become a step ahead of everybody else. The five Morgan portfolios sold under their own brand all produced better than the Standard & Poor 500-stock index over the 12 months through March. Which would mean their theory is working.

Finding Enlightenment (and we wernt really looking for it) :: Essays Papers

Finding Enlightenment (and we wern't really looking for it) I knew it was coming. I just didn’t know what it would look like, how close we would be, or if it would trap us like the siege of St. Petersburg. It is hard to explain why I didn’t ask these kinds of questions before the twenty-three miles we’d gone that day, but it is easy to see why I couldn’t picture such things. Being in new places and seeing new things everyday and you just end up succumbing and rolling with the punches. The magnitude of what we were in for could not be documented on a chart or a map, which was the extent of our resources. For whatever incredible inventions humans have created, numerically speaking, the earth in all its vastness and beauty easily outnumbers human technology. There are trillions of enormous and miniscule creatures, spectacular mountain ranges that reach so high they touch the limit of mortal tolerance. There are evolved and intricately worked canyons and caves, wide fields and forests that never seem like they change but in all actuality have never stopped moving or changing since the beginning of time. We as humans look mighty ignorant to believe that we are the most special things ever to enter this world, especially when we are more destructive to our symbiosis with the natural world than preservers of our relationship with it. But on this particular day when I was confronted with something I’d never seen before, not even on television or in a text book , there it was so enormous that from 2 miles away I felt like I could reach out and touch it. Realistically, had I been close enough to scrape my frail human skin across its front side there is no doubt in my mind that I would not be around to tell the story today. That morning started so early, I felt as though the night before never came. During the summer in Alaska, the sun never sets and thus the day never ends, and if the day never ends then the next day never actually begins. I constantly tangled with this very confusing theory and lasted long into the night writing in my journal, fishing while my two-week permit lasted, or basking in the beauty that was and is Alaska. It was Day 20 of my 30-day excursion to Prince William Sound in Southern Alaska.

Green Energy Essay

This is a serious issue in many countries and is harmful to humans’ and animals’ health, the environment and also increases pollution (Veziroglu 2007). Now, it is the time to face these problems by using clean energy such as solar, wind and water. Wagner & Mathur (2011) state that hydropower is the most efficient renewable energy, while Veziroglu (2007) claims that hydrogen is the key to the solution in the 21st century. Therefore, this essay will focus on energy sources water and hydrogen. The first part will analyse how to use water to produce a large amount of power in several ways. The second will discuss the effect of hydro energy. The third point will explain where hydrogen comes from and how to use it. The last section will describe the reason why many researchers and industrialists are interested in using hydrogen power. It is argued that using hydro power and hydrogen energy in many countries can decrease CO2 emissions that are the main cause of climate change and create an amount of clean energy, although these sources of energy have some negative impact and requires high investment costs. Hydro is a large natural resource that can be used to generate power in different ways. Hydro means water which is a significant power source to generate electricity. Destouni & Frank (2010) state that hydro-electric is a large resource, and it is more stable and reliable than other resources when they are compared. Additionally, the electric can be produced from water by using generator in many ways. Wagner & Mathur (2011) reveal that there are three ways which are river power plant, storage power plant and oceanic power plant. Firstly, they state that river power plants create power by the flowing and dropping of elevation of water. For storage power plants, they reveal that they generate electricity when the reservoir allows water to fall from natural resources such as Mountain Lake and artificial resources such as dam. For example, they point out that the biggest storage energy stations is the Three Gorges Dam in China which creates over 25 times more electricity than a coal-fired energy station on the basis of capacity. Secondly, another power plant uses water from the ocean such as wave, tide and the different temperatures of the sea to produce energy. Furthermore, hydro-energy is the main source of electricity in some countries. For instance, the percentage of using hydropower in Norway, Brazil and Canada are 99, 84 and 58, respectively (Wagner & Mathur 2011). In the future, the global product of hydro-electricity tends to be growth. Destouni and Frank (2010) suggest that it will increase around 20 percent by 2050 for decreasing the using of fossil fuel and carbon emission. Hydro energy has negative and positive sides that affect human lives. Firstly, all hydro power plants require a great amount of capital. Secondly, river plants produce small amounts of energy compared with other hydropower plants because this type does not use the full flow of the river, so the energy is not sufficient for many households. Thirdly, large dams could lead to floods in the cities which are situated lower than the dams because of overload caused by heavy rain or damage caused by earthquakes (Wagner & Mathur 2011). Moreover, hydro plants could impact on environment. For example, large dams can interrupt fish’s lives when fish try to swim upstream and deplete natural animal habitat for birds and ducks that have to move to another area as shown in the O’Shaughnessy Dam in the United State which destroyed some parts of Yosemite National Park. Moreover, over one million people were forced to move out their villages when China built the Three Gorges Dam project (National Geographic 2012). On the other hand, there are many advantages of hydro power plants. Wagner & Mathur (2011) indicate that storage power plants can generate large amount of energy, and when well managed can avoid flooding, and can provide water for farmers whenever they demand because the dams collect water all year. In addition, dams have the efficiency of controlling the water that can begin, stop and generate power immediately. Furthermore, the average cost to invest in this power is lower than the other sources, and it can be used longer than 50 years. For example, the plant in Darjeeling in India is installed in 1897 (Wagner & Mathur 2011). According to National Geographic (2012), hydropower is sustainable and clean source because of water cycle that water transforms to steam and come back to water again, and no greenhouse gases such as carbon dioxide which pollute into the air so that it decreases impact on environment and reduce the causes of global warming. Another widespread renewable energy is hydrogen which is a basic source which can be produced from natural and artificial resources and can use in many kinds of industries for reducing carbon dioxide emissions. Hydrogen is made from primary sources such as solar, nuclear, water and fossil fuel (Fig. 1). Edwards, Kuznetsov & David (2007) point out that a fuel cell is a device for generating electricity and recharging power by oxidation between hydrogen and oxygen from the air though electrodes and this process will continue until no fuel and air (Fig. 2). Therefore, many countries select hydrogen energy to solve climate change problems that are caused by the use of fossil fuel. For example, some countries which are interested in using hydrogen power are the United States and Japan who spend a lot of money investing in hydrogen energy projects both to decrease carbon emissions, and as an alternative power resource (European Commission 2003). Hydrogen energy and fuel cell have some pros and cons for decision to use in society such as vehicles, aerosol and stationary. The advantages of hydrogen power and fuel cell are cycling of water, low or zero carbon emission, high efficiency and power quality, and low noise. As a result, these advantages will reduce pollution and eliminate greenhouse gases which cause ozone layer depletion. Moreover, these systems are used in wide range such as hospitals, transport, and IT centres (Edwards, Kuznetsov & David 2007 and Veziroglu 2007). In transport, hydrogen energy has been used in transport because it provides good performance and high convenience such as smoothing and low noise, and also it is used for silent power of airspace and producing high levels of power for advanced soldier uniforms in military program. Furthermore, technology such as computers, telephone and radios also use hydrogen and fuel cell in recent year because it can provide long life batteries. However, it cost a great amount of money to hydrogen project and sometimes it can use in short time just thousands hours (European Commission 2003). In addition, Veziroglu (2007) reports that some process will produce other gases not only hydrogen such as nitrogen oxide group can cause global warming. In conclusion, the advantage of hydropower is providing the amount of energy that is sufficient for the requirements of every household, and the advantage of hydrogen energy is that it can be used in many industries such as cars and airplanes. Moreover, both of them, which are clean and sustainable energy systems, reduce carbon emissions. Furthermore, the cost of these kinds of energy will decrease as these systems become more prominent and will be used more widely in the future. Therefore, hydropower and hydrogen energy are likely to be used in the future to decrease the causes of climate change.

Boys vs. Girls

Commonsense beliefs about boys and girls are not arbitrary. According to Archer and Lloyd (2002), they are associated with coherent ways of understanding the world in which we live, which for many centuries have been presented to each succeeding generation in the form of religious truths. The following little experiment demonstrates one situation where girls have outdone boys. Three boys and three girls were asked to kneel on the floor with their legs together by their high school teacher.All of them were made to bend forward and put their elbows up against their knees. Lipstick containers were placed upright at the end of the six young people’s fingers. Then, they were made to kneel up straight with their legs still together, with hands clasped behind their backs above their waists. They were then told to keep their arms and legs in their position while leaning forward, knock the lipstick container over their noses and return to the kneeling-up position. The observation was t hat girls can do it while boys can’t.The reason that this happened is because girls tend to have more body weight in the lower half of their bodies than boys do so they can balance better. But this little story/experiment does not prove that girls are better than boys. There are just some things that girls perform better than boys, AND vice versa. For instance, boys are observed to do significantly better than girls at mathematics, and understand relationships in the physical world better than the opposite sex (Archer and Lloyd, 2002).Conversely, girls are better at processing language than boys, which goes a long way toward explaining why girls overall have better communication than their gender counterparts. All of these examples and the experiment stated above just means that girls and boys are different. Differences do not imply an order of rank. Oranges and apples are different, but that doesn’t mean oranges are better than apples. Ovaries and testicles are differ ent, but that doesn’t mean that one is better than the other. WORK CITED Archer, J. & Lloyd, B. (2002). Sex and Gender. (2nd Ed. ). New York: Cambridge University Press. Boys vs. Girls Boys and Girls had always been perceived to be greatly different from each other. It has been stereotypically observed that when the doctor shouted, â€Å"It's a baby boy,† the nurse will wrap him around a blue cloth while on the other hand when the doctor declares, â€Å"It's a baby girl,† a pink cloth will then be wrapped around her. But aside from the usual determining colors associated with boys and girls, what other factors set both genders apart and make them distinct? According to Armin Brott, baby boys are slightly heavier and longer than girls at birth.This is why many first-time mothers spend longer labor hours and it ultimately leads to higher birth trauma resulting to more irritable actions among the boys than the girls (Brott, 2008). He also adds that boys are more inclined in a more energetic and rough games as compared to the girls who like to pretend and mimic (Brott, 2008). In accordance to this perception, Leonard Sax, a doctor and a psychologist asser ts that boys and girls differ in their view of the surroundings and environment.In studying the outlook of the girls, he showed an image with â€Å"a girl, a dress, a pet, the sun, flowers, rainbow and all those colors,† which has been the same kind of drawing girls all over the world has drawn (Selliot, 2008). On the other hand, he presented an image of â€Å" bloody red battle scenes, gray rocket ships and black speeding vehicles,† all of which are the same content of a boy's painting (Selliot, 2008). Furthermore, Brott observed that the girls take in greater sensory than boys wherein they can taste more, and tend to exhibit a greater need to be touched.There are actually more differences associated to the two genders. However, it is really difficult to identify who is greater or more superior than the other because as observed in the above comparison, both have their own unique personalities and inclinations which help develop their skills and perception in the thin gs around them. It is therefore important to appreciate the characteristics and traits that set the boys apart from the girls and vice-versa and what makes them special in their own ways. References Brott, A.

The e-learning community Essay Example | Topics and Well Written Essays - 1500 words

The e-learning community - Essay Example This site is reminiscent of many other open source code sites, provides a mixture of community information areas for those who are developers and those who simply want to understand what Moodle is about. Like many open source website, there are continual downloads and as such are constantly updated on a regular basis. The site does presents a very balanced view as it is open source software, it is open to the internet community as a whole. This is an excellent way to continually improve a site with respect to having developers add to the source code as well as reporting and helping, in some cases, to fix bugs that affect the software. The site was extremely easy to navigate due to it's simple site architecture in place. It has general areas that all sites require and conforms to the standards required by open source code sites. The site is very crisp and clean and is not overly complicated with respect to needing to go where you need to. Navigation is extremely well thought out. The site is clean, and not overcrowded by site advertising and lets you find the areas that the visitor needs to go to. The menu system to the left of the site is extremely easy to navigate and, for example, if you do to documentation, that is the first and only place you need to go to find every piece of documentation you would need to find. This style of site allows for the average user looking for a solution to easily understand what they want without being crowded out by technical language. 5. How the site could be improved. I would only say the site only needs improvement in understanding what the open source software is exactly. Moodle gives you a "welcome to moodle", but, unless you are familiar with open source code and what it is about, it is impossible to understand the technical language. Although they provide links to the different definitions of terminology, an unfamiliar and non-technical person may turn away from this site. It would also be helpful to use dynamic flash images or pages instead of static images that don't lend to an overly receptive front page, or, for that matter, cascading sheets. atutor.ca site This website is entirely formatted and styled after the Microsoft site in its arrangement of the menu system and overall style sheets. 1. What information did the site cover, e.g. did it try to present a summary of the facts or did it also give opinions Did it try to give complete and up- to-date coverage, or did it appear to be selective The site is entirely composed of presenting to the visitor what the open source web-based software is inclusive of and as such provides a very good description of what it is representing. As with many open source sites, this too, like Moodle, has continual updates on a daily basis to any fixes to the code itself or those that report a problem they can track it in the documentation section. 2. Did the site present a balanced view or did it represent one perspective The site does

New Public Management has led to a convergence between the public and Essay

New Public Management has led to a convergence between the public and private sector and enhanced the delivery and organization of public services. Discuss - Essay Example In some public organizations when the measure of success is considered to be on the basis of powerlessness or apathy, all efforts would be geared towards this even if it compromises the quality of services given to the service users. In such instances, the traditional tools and avenues for measuring success in the business and private sector cannot be employed. While the two sectors share several similarities in terms of management methods, they are not entirely the same. This difference can only be appreciated when one accepts that the administration means as well as the values in the sectors are very much dissimilar. Ferlie et al. (2006) notes that the public sector greatly values the interest of the public and also puts emphasis on political compromise when undertaking its initiatives. On the other hand, the private entities are more focused on profitability and they therefore strive to come up with ways of management and operation that will ensure that they achieve the goals. Despite this being the case, there has been a very interesting phenomena whereby there appears to be a convergence between the public and the private sector aided by the New Public Management (NPM). This treatise discusses how this convergence has taken place and the effect it has had on the delivery and the organization of public services. Esping-Anderson (1990) remarks that in order to appreciate the effect that New Public Management has had on both the private and private sector operations, it is imperative to explore the traditional sectors and how the two operated in terms of management and priorities. Haynes (2003) says that businesses in the private sector normally engage in the creation and distribution of services and other commodities to be able to enhance the quality of life of the buyers while at the same time making profits for the shareholders. This, therefore, calls for constant innovations to reward

Contemporary social problems paper Essay Example | Topics and Well Written Essays - 500 words

Contemporary social problems paper - Essay Example These concerns are real social problems that the nation faces at present. There have been significant changes in the population growth since 1967 and it has been unevenly distributed, since 1970, with growth in the South and West, and loss in the other areas. This will result in many types of social problems. Already there are many problems like increased traffic congestion, proliferation of foreign language TV channels, expansion in the number of professional teams and so on. These are minor issues compared to the more serious issues connected with environment, education system, health care system, political system and others. The racial and ethnic disparities that the US is facing put the nation in great distress. The difference in these areas can turn up as decisive factor in the making up of the modern civility. The life in the nation is conditioned by the racial and ethnic group one belongs to. There is now a substantial gap between the minority and the White which can result in the social unrest as well. The minority that is growing at a fast rate will hold increasing share of the future work, resulting in the social imbalance.

City Genral plan Essay Example | Topics and Well Written Essays - 1000 words

City Genral plan - Essay Example As well as activities that are acceptable on every land parcel, this provides every area with compatibility and continuity as well as those individuals who border those areas. Taking an example of a general plan of Albany, in New York and, the element of land use element has been addressed of which its purpose is to benefit individuals and shape development of cities this is vividly seen in reference with the cities prospective of which its plans are to shape the road ahead, with a target that they feel should be accomplished in the future twenty years from the current time. In the land use plan land uses a pattern known as the spatial distribution all over the city and ways in which for instance the occupants or even enterprises make use of land that is available. The goals that are entailed in this element are simple but at the same time work best, it ties to the six original visions statements which are original and its aim is to support the adoption of a balanced future land use pattern standing with these concepts. There’s also strategies in the land use element and has suggestions such as the utilization of properties that have been neglected or could be they are not occupied, maps are used to guide decisions in the transportation connections land generally the use of land. The land use map outlines a number of lands uses for instance what is referred to as the downtown hub. In all of these corridors there’s employment and education centers that are contained and their results lead to a prosperous economy and revitalized development of the city. The land use element is essential because it is what is used to guide future development and make land use decisions that maintain attractive and economically sustainable city, through considering citizens satisfaction survey in making improvements it can lead to a commendable city development. While dealing with the land use element hardships that are involved in matters like understanding nature an d the limitations the planners coaching and motivation bring to decision concerning how land is used. In land use element we see that the cultural factors are mainly less emphasized in comparison to the physical and even the economic and social characteristics in making decisions on land use patterns. For instance in places that are have the potential of productivity according to soil and the slope parameters and to the existing social economic aspect do not maintain the activities that a land use would assign to them. The cultural factors that affect land use element and mostly in development of a city are information, the technology and the biasness that comes along this factors could either affect land use component positively or negatively. Due to cultures being different from one another, there happen that evaluation on land use can’t be standardized for similar physical conditions. People living and working in a given space often there’s is disregard the proposal s of studies on the constraints that are physical in the area. When we have people living and working together at a place there’s usually disregard of proposals on studies on the physical parameters of the area. Land use element evaluation on the Albany city portrays the potential for production and loss under a specified land use thus there is no possibility of commanding a decision that depends on the individuality of the populations influenced. Some of the systems attributes turn out to be dangerous to the

Judaism paper Research Example | Topics and Well Written Essays - 1000 words

Judaism - Research Paper Example Certain varieties of Judaism consider the idea that all Jewish teachings must strictly be adhered to (Wylen, 2000). Although, there are other forms of Judaism that believe teachings that encourage on how to usher a morality in human lives are obligatory, much less, essential; others can be considered as discretionary or optional. For the reason that Judaism is an assorted religion with an extensive range of beliefs and practices, it must not be presupposed that a Jew has certain types of beliefs or follows precise forms of religious practice (Eisenberg, 2004). Various types of Judaism are linked by an intense impression of "peoplehood" (ICS, 2013), a shared inheritance, tradition or custom, and collective values and standards. Judaism gives Jews with guidance on how to carry out their religion and inspire good values (ICS, 2013). These instructions descend from numerous bases that include Jewish sacred texts such as the Bible and the Talmud (ICS, 2013). Other Jewish texts such as the subsequent literary works written by rabbis and philosophers are also being used. Judaism is one of the most important religions that are still being practiced today. Thus, it sensibly important to dig in deeper to its historical derivations, and the significant figures, observance, teachings, and events that can be relatively associated with it. This paper shall elaborate on these categories, which should provide readers a general overview of Judaism. Judaism and Abraham One of the fundamental teachings of Judaism is the belief that there is only one God, a belief that is also known as ethical monotheism (Wylen 2000; ICS, 2013). Judaism teaches that there is a lone God who created the universe and everything that is in it; a Supreme Being who cherishes and tends humanity; a God who desires that His people will live ethical lives (ICS, 2013), which makes it a strong cause that having a profound understanding of Judaism is crucial in appreciating the historical lineage of the world. The Old Testament confirms that Abraham started off monotheism or the belief in one God, and was the first person to refuse idol worship. Abraham is a fundamental component of Judaism in that he was considered to be the Father of the Jewish people and that it was through him and his offspring that a covenant was handed on to succeeding generations (Pellach, 2006). The Abrahamic Covenant, which can be found in Genesis 12-17, elaborates three main issues: (1) God would bestow Abraham the Land of Canaan and make him the father of all nations and of his progenies; (2) God would create a great nation through him; and (3) God would yield a blessing to those who consecrate him and curse those who curse him. In Genesis 12:3 God says, â€Å"I will bless those who bless you, and I will curse him who curses you; and in you all the families of the earth shall be blessed† (New International Version). Abrahams covenant is particularly important because it serves as the source to the Bible and world history (Pellach, 2006). The basis of almost all Christian teachings is rooted on the belief that God has a chosen people, which will reveal themselves in the last days of the earth. Although, some people in various civilization and cultures believe that the covenant no longer applies today, the Bible reaffirms that Abrahamic covenant is still in effect. The Bible says, â€Å"He [God] remembers his covenant forever, the word which he commanded,

Islam, Quran, Sunnah Essay Example for Free

Islam, Quran, Sunnah Essay The paper talks about the importance of the Quran and the Sunnah as the primary sources of Islamic beliefs, practices, and law, and their influence in Muslims daily life Islam. Islam is a religion that was originated when Prophet Mohammad (PBUH) began to spread the teachings of Allah (God of the followers of Islam) in the 7th century. God choose Prophet Mohammad as his last messenger and ordered the Prophet to spread his teachings and to ask everyone to believe in the oneness of Allah and the people who follow Islam are called the Muslims. Quran is the book of God that was revealed to Prophet Mohammad through Angel Jibrael and the Muslims consider the book to be a very Holy Book of God that covers each and every aspect of life and the word Quran stands for recitation. It talks about everything a human being needs to seek guidance for and it tells the right way of how to live your life. When the Quran was revealed, the language it was written in was Arabic, however, now the book is available in all translations so that people can read and understand the true context of the book well and can follow its teachings. The teachings in the Quran differentiate the right from wrong and also tell the benefits of selecting the right path and the consequences of selecting the wrong path. The Muslims who select the right path would always benefit in the world and also in the hereafter i. e. life after death. Quran does not force anyone to adopt the right or the wrong path but it does portray the negative and the positive aspects of the path the Muslims select. As mentioned above, Quran is a complete book of guidance for the Muslims and it covers every aspect of life. To further explain this, I would give some examples of what Quran speaks of. Some of the very basics that Islam as well as other religions also ask the human community to do is to always select the right path that means they should not cheat anyone, they should not lie, they should not betray anyone or should not take the sue share of another person. As said by the Quran and the Prophet Mohammad, the Muslims who will follow the teachings of Islam and implement the etchings of the Quran will always be successful in every way and the most important thing is that Allah (God) will also love such people and this would then result in the worldly reward or the reward of going to Heaven after death. When the Quran was revealed, the companions of Prophet Mohammad used to write down each and every verse of Allah and the Book was later complied and the text is still the same as it was when it was revealed. The Muslims also believe that each and every word is the Book is the word of Allah. Quran is thus very important in shaping up the life of a Muslim and is one of the primary sources of Islamic beliefs. Other than the Quran, the Sunnah is also considered to be one of the primary sources of the Islamic believes. The word Sunnah basically refers to the path that Prophet Mohammad choose to live his life and it includes the traditions he followed, his actions and words, what he practiced. Overall, it basically the way he had chosen to live his life. The Muslims follow the example of the Prophet Mohammad mainly through the Hadiths. Prophet Mohammad did each and everything God asked him to do and led his whole life always by choosing the right path. For instance, Prophet Mohammad taught the Muslims to offer prayers both individually as well as in congregation especially for the men and that is what the Muslims follow today especially on every Friday when all Muslim men go to the mosque to offer the Friday prayers. Since the time of Prophet Mohammad, people have learned how to live in a practical manner and this has been transmitted to their future generations. The Muslims also adopt the living style of the Prophet that includes his habits and style and the way he dealt with the other people. He was always considerate and caring, he always used to forgive others and he always used to be polite with others and this is what the Muslims must inculcate in themselves as well. The Quran also talks about Prophet Mohammad and has commanded the Muslims to follow what the Prophet has taught and to obey the teachings of the Prophet at all times. The significance of Sunnah is moreover also to please God by doing what His most loved Prophet did and to embrace his way of living. Both the Quran and the Sunnah therefore, play a very vital role in shaping up the life of a Muslim and so these have a great influence on the lives of the Muslim community. Work Cited Neusner, Jacob.

Water Content Or Moisture Content Environmental Sciences Essay

Water Content Or Moisture Content Environmental Sciences Essay Water content  or  moisture content  is the quantity of  water  contained in a material, such as  soil  (called  soil moisture),  rock,  ceramics, fruit, or  wood. Water content is used in a wide range of scientific and technical areas, and is expressed as a ratio, which can range from 0 (completely dry) to the value of the materials  porosity  at saturation. It can be given on a volumetric or mass (gravimetric) basis. The water content of a material is used in expressing the phase relationships of air, water, and solids in a given volume of material. In fine-grained (cohesive) soils, the consistency of a given soil type depends on its water content. The water content of a soil, along with its liquid and plastic limits as determined by Test Method  D4318, is used to express   its relative consistency or liquidity index. The quality of the result produced by this standard is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used. Agencies that meet the criteria of Practice  D3740  are generally considered capable of competent and objective testing/sampling/inspection/etc. Users of this standard are cautioned that compliance with Practice  D3740  does not in itself ensure reliable results. The mass of water used in the above expression is the mass of free pore water only. Hence for moisture content determination the soil samples are dried to the temperature at which only pore water is evaporated. This temperature was standardized 105 C to 110 C. Soils having gypsum are dried at 60C to 80 C. The quantity of soil sample needed for the determination of moisture content depends on the gradation and the maximum size of particles. Following quantities are recommended. Soil Max quantity used (gm) Coarse gravel 1000 to 2000 Fine gravel 300 to 500 Coarse sand 200 Medium sand 50 Fine sand 25 Silt and clays 10 to 25 Moisture content affection : Always the amount of moisture contents affects the soil strongly by different issues , and this is the dramatically classifications of the different amounts of the moisture content in the soil : The soil is called ( brittle solid ) when its in a dry state or have a very little amount of moisture content inside the soil , and it will be hard and brittle as a result of that , though it breaks before it will deform ( hard candy ). The soil is described as ( semi-solid ) when its have a little amount of moisture content in it , thatà ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢s not able to cancel the solidity in the soil because of the little amount of it in the soil , and the behavior of the soil will be between the brittle and ductile state , and though it deforms permanently but with cracks ( like stiff cheese ). The soil described also as ( plastic ) when it have a noticed amount of moisture content which have an appearance affect in the soil , when the amount of the water content is nor little neither much in the soil , and the behavior of the soil in the state will noticed directly while catching the samlple of the soil by hand , it will have a very ductile , malleable behavior , thatà ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢s will deform without cracking ( like play-doh ). The soil in the last case , is the ( liquid ) soil which will have for sure a big amount of moisture content inside it , it we can notice that easily by slight moving or even by the naked eye , which will be like a thick or thin viscous fluid or like a soup. Actually always there is a limits between each state of the moisture content for the soil , and these limits called the consistency or atterberg limits of the soil , and to talk more briefly about the ( Atterberg Limits ) : The  Atterberg limits  are a basic measure of the nature of a fine-grained  soil. Depending on the  water content  of the soil, it may appear in four states: solid, semi-solid, plastic and liquid. In each state the consistency and behavior of a soil is different and thus so are its engineering properties. Thus, the boundary between each state can be defined based on a change in the soils behavior. The Atterberg limits can be used to distinguish between  silt  and  clay, and it can distinguish between different types of silts and clays. These limits were created by  Albert Atterberg, a  Swedishchemist.[1]  They were later refined by  Arthur Casagrande. These distinctions in soil are used in picking the soils to build structures on top. Soils when wet retain water and expand in volume. The amount of expansion is related to the ability of the soil to take in water and its structural  make up  (the type of atoms present). These tests are mainly used on clayey or silty soils since these are the soils that expand and shrink due to moisture content. Clays and silts react with the water and thus change sizes and have varying shear strengths. Thus these tests are used widely in the preliminary stages of building any structure to ensure that the soil will have the correct amount of  shear strength  and not too much change in volume as it expands and shrinks with different moisture contents, aand here is the informations about the three atterberg limits , shrinkage , plastic and liquid limit : Shrinkage limit The shrinkage limit (SL) is the water content where further loss of moisture will not result in any more volume reduction.[2]  The test to determine the shrinkage limit is  ASTM International  D4943. The shrinkage limit is much less commonly used than the liquid and plastic limits. [edit]Plastic limit The plastic limit is determined by rolling out a thread of the fine portion of a soil on a flat, non-porous surface. The procedure is defined in ASTM Standard D 4318. If the soil is plastic, this thread will retain its shape down to a very narrow diameter. The sample can then be remoulded and the test repeated. As the moisture content falls due to evaporation, the thread will begin to break apart at larger diameters. The plastic limit is defined as the moisture content where the thread breaks apart at a diameter of 3 mm (about 1/8). A soil is considered non-plastic if a thread cannot be rolled out down to 3mm at any moisture. [edit]Liquid limit The liquid limit (LL) is the water content at which a soil changes from plastic to liquid behavior. The original liquid limit test of Atterbergs involved mixing a pat of clay in a round-bottomed porcelain bowl of 10-12cm diameter. A groove was cut through the pat of clay with a spatula, and the bowl was then struck many times against the palm of one hand. Casagrande subsequently standardized the apparatus and the procedures to make the measurement more repeatable. Soil is placed into the metal cup portion of the device and a groove is made down its center with a standardized tool of 13.5 millimetres (0.53  in) width. The cup is repeatedly dropped 10mm onto a hard rubber base at a rate of 120 blows per minute, during which the groove closes up gradually as a result of the impact. The number of blows for the groove to close is recorded. The moisture content at which it takes 25 drops of the cup to cause the groove to close over a distance of 13.5 millimetres (0.53  in) is defined as the liquid limit. The test is normally run at several moisture contents, and the moisture content which requires 25 blows to close the groove is interpolated from the test results. The Liquid Limit test is defined by ASTM standard test method D 4318.[3]  The test method also allows running the test at one moisture content where 20 to 30 blows are requi red to close the groove; then a correction factor is applied to obtain the liquid limit from the moisture content..[4] The following is when you should record the N in number of blows needed to close this 1/2-inch gap: The materials needed to do a Liquid limit test are as follows Casagrande cup (liquid limit device) Grooving tool Soil pat before test Soil pat after test Another method for measuring the liquid limit is the  fall cone test. It is based on the measurement of penetration into the soil of a standardized cone of specific mass. Although the Casagrande test is widely used across North America, the  fall cone test  is much more prevalent in Europe due to being less dependant on the operator in determining the Liquid Limit. http://upload.wikimedia.org/wikipedia/commons/thumb/1/16/Atterberg_limits_02.JPG/220px-Atterberg_limits_02.JPG http://upload.wikimedia.org/wikipedia/commons/thumb/2/24/Casagrande_2.JPG/220px-Casagrande_2.JPG [edit]Importance of Liquid Limit test The importance of the liquid limit test is to classify soils. Different soils have varying liquid limits. Also to find the plasticity index of a soil you need to know the liquid limit and the plastic limit. [edit]Derived limits The values of these limits are used in a number of ways. There is also a close relationship between the limits and properties of a soil such as compressibility, permeability, and strength. This is thought to be very useful because as limit determination is relatively simple, it is more difficult to determine these other properties. Thus the Atterberg limits are not only used to identify the soils classification, but it allows for the use of empirical correlations for some other engineering properties. [edit]Plasticity index The plasticity index (PI) is a measure of the plasticity of a soil. The plasticity index is the size of the range of water contents where the soil exhibits plastic properties. The PI is the difference between the liquid limit and the plastic limit (PI = LL-PL). Soils with a high PI tend to be clay, those with a lower PI tend to be silt, and those with a PI of 0 (non-plastic) tend to have little or no silt or clay. PI and their meanings 0 Nonplastic (1-5)- Slightly plastic (5-10) Low plasticity (10-20)- Medium plasticity (20-40)- High plasticity >40 Very high plasticity [edit]Liquidity index The liquidity index (LI) is used for scaling the natural water content of a soil sample to the limits. It can be calculated as a ratio of difference between natural water content, plastic limit, and liquid limit: LI=(W-PL)/(LL-PL) where W is the natural water content. The effects of the water content on the strength of saturated remolded soils can be quantified by the use of the liquidity index, LI: When the LI is 1, remolded soil is at the liquid limit and it has an undrained shear strength of about 2 kPa. When the soil is at the plastic limit, the LI is 0 and the undrained shear strength is about 200 kPa.[4][11] [edit]Activity The activity (A) of a soil is the PI divided by the percent of clay-sized particles (less than 2 ÃŽÂ ¼m) present. Different types of clays have different specific surface areas which controls how much wetting is required to move a soil from one phase to another such as across the liquid limit or the plastic limit. From the activity, one can predict the dominant clay type present in a soil sample. High activity signifies large volume change when wetted and large shrinkage when dried. Soils with high activity are very reactive chemically. Normally the activity of clay is between 0.75 and 1.25, and in this range clay is called normal. It is assumed that the plasticity index is approximately equal to the clay fraction (A = 1). When A is less than 0.75, it is considered inactive. When it is greater than 1.25, it is considered active. After briefly explaining the the differences between the amounts of moisture content in the soil , we should explain a vey important issue , which is the methods of affection of the moisture content in the soil which is : Strength decreases as water content increases. à ´Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â€š ¬Ã… ¡Ãƒ ¢Ã¢â€š ¬Ã… ¾ Soils swell-up when water content increases. à ´Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â€š ¬Ã… ¡Ãƒ ¢Ã¢â€š ¬Ã… ¾ Fine-grained soils at very high water content possess properties similar to liquids. à ´Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â€š ¬Ã… ¡Ãƒ ¢Ã¢â€š ¬Ã… ¾ As the water content is reduced, the volume of the soil decreases and the soils become plastic. à ´Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â€š ¬Ã… ¡Ãƒ ¢Ã¢â€š ¬Ã… ¾ If the water content is further reduced, the soil becomes semi-solid when the volume does not change. And to talk more about the affection of the moisture aontent in the soil , this is a general affection of the moisture content in the soil at nature : The effect of increasing soil  moisture content  on soil temperature, soil reflectance and soil heat storage is studied in this work. The results show that an increase in  moisture content  decreases the soil temperature differences between day-time and night-time, which provides protection to the plant root system against sharp and sudden changes of soil temperature. It is also found that the solar energy absorption increases as the  moisture content  increases, which results in a higher heat storage capacity at higher  moisture content. Finally, plant growth rate and yield increased due to the modification of plant climate at higher moisture content Water content is an important property of soils, in ¯uencing soil solution chemistry and nutrient uptake by plants.Morphology and other speci ®c properties of the root, nutrient concentration in the soil solution, the mobility of nutrients in the soil, and supply from solid phases, aÃÆ' ¯Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬ect nutrient uptake (Nye and Tinker, 1977; Barber, 1995). Consequently, there are consistent diÃÆ' ¯Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬erences in concen- trations of elements near the rhizoplane at a range of soil water contents (Dunham and Nye, 1976). Soil chemical properties may exert a profound in ¯uence on growth and performance of plants (Grime and Curtis, 1976), and soil concentrations of several elements may be closely related to oristic composition (Tyler, 1996a). Under  ®eld conditions, soil moisture  ¯uctuates with temperature and rainfall. By changing soil solution chemistry, moisture  ¯uctuations could regulate the availability of nutrients, and the  ®eld distributi on of plant species. Water has a very different thermal conductivity than most soil particles and air (the thermal properties of the soil are determined by these three). The thermal conductivity of water is much greater than that of air, so the higher the soil moisture content the greater the thermal conductivity.  The greater the soil moisture content, the more the soil thermal conductivity is like that of water. Therefore, a saturated soil has a conductivity near that of water.  However, just because the soil moisture content is high, doesnt mean that the soil will warm up faster in the Sun than a dry soil. Evaporation of the water will remove much of the Suns energy before the soil will have a chance to warm.  Therefore, dry soils do warm up faster from sunlight and cool faster at night. This is assuming that there isnt a vegetation cover over the soil. Most wet soils evaporate the water, keeping the soil from warming as fast during the day, and cool more slowly at night because of their greater heat capacity (because of the higher water content).   Moisture content phase diagrame : this is a rough photo about the general form of the phase diagram of the soil , that we use always for calculation done for moisture contents and all other issues in the soil : http://upload.wikimedia.org/wikipedia/commons/thumb/5/54/Soil-phase-diagram.svg/300px-Soil-phase-diagram.svg.png Weight Components: à ´Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â€š ¬Ã… ¡Ãƒ ¢Ã¢â€š ¬Ã… ¾ Weight of Solids = Ws à ´Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â€š ¬Ã… ¡Ãƒ ¢Ã¢â€š ¬Ã… ¾ Weight of Water = Ww à ´Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â€š ¬Ã… ¡Ãƒ ¢Ã¢â€š ¬Ã… ¾ Weight of Air ~ 0 Volume Components: à ´Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â€š ¬Ã… ¡Ãƒ ¢Ã¢â€š ¬Ã… ¾ Volume of Solids = Vs à ´Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â€š ¬Ã… ¡Ãƒ ¢Ã¢â€š ¬Ã… ¾ Volume of Water = Vw à ´Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â€š ¬Ã… ¡Ãƒ ¢Ã¢â€š ¬Ã… ¾ Volume of Air = Va à ´Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â€š ¬Ã… ¡Ãƒ ¢Ã¢â€š ¬Ã… ¾ Volume of Voids = Va + Vw = Vv Weight-Volume Relationships : à ´Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â€š ¬Ã… ¡Ãƒ ¢Ã¢â€š ¬Ã‚   Steps to develop the weight-volume relationship à ´Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â€š ¬Ã… ¡Ãƒ ¢Ã¢â€š ¬Ã… ¾ Separate the three phases à ´Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â€š ¬Ã… ¡Ãƒ ¢Ã¢â€š ¬Ã… ¾ The total volume of a soil à ´Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â€š ¬Ã… ¡Ãƒ ¢Ã¢â€š ¬Ã… ¾ Assuming the weight of air (Wa) to be negligible, the total weight is then given as V = Vs + Vv = Vs + Vw + Va W =Ws +Ww Objectives Practical Applications This is some properties that we could conclude the state of it in the soil from knowing the amount of moisture content in the soil : à ¢Ã¢â‚¬Å¡Ã‚ ¬ Storability of the soil à ¢Ã¢â‚¬Å¡Ã‚ ¬ Agglomeration in the case of powders à ¢Ã¢â‚¬Å¡Ã‚ ¬ Microbiolgical stability à ¢Ã¢â‚¬Å¡Ã‚ ¬ Flow properties, viscosity à ¢Ã¢â‚¬Å¡Ã‚ ¬ Dry substance content à ¢Ã¢â‚¬Å¡Ã‚ ¬ Concentration or purity à ¢Ã¢â‚¬Å¡Ã‚ ¬ Commercial grade (compliance with quality agreements) à ¢Ã¢â‚¬Å¡Ã‚ ¬ Nutritional value of the product à ¢Ã¢â‚¬Å¡Ã‚ ¬ Legal conformity (statutory regulations governing food) Objectives : To learn the procedures of finding moisture content in the soil , and the variety in methods using to determine the moisture content. To determine the quantity of moisture content in the soil by good , accurate , safe , sheep way. To learn the differences in affection on the soil due to different amounts of moisture content in the soil To know the performance of the soil due to different amounts of moisture contents. To know how to use geotechnical laboratory tools, Such as the oven , balance , soil containers and all other different tools To know the importance of this experiment in the field work and how it affects the type and method of foundations must put upon different types of structures. Practical Applications : Moisture content plays an important role in understanding the behavior of fine grained soils. It is the moisture content which changes the soils from liquid state to plastic and solid states. Its value controls the shear strength and compressibility of soils. Compaction of soils in the field is also controlled by the quantity of water present. Densities of soils are directly influenced by its value and are used in calculating the Stability of slopes, bearing capacity of soils-foundation system, earth pressure behind the retaining walls and pressure due to overburden. The knowledge of determining the moisture content is helpful in many of the laboratory tests such as Atterbergà ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢s limits, shears strength compaction and consolidation. This experiment may be performed by two different methods. Geotechnical Engineering- I A. Oven drying method B. Torsion balance moisture content Actully we use the moisture content experiment mainly for getting the amount of water content inside the soil to be able to make the classification needs in the field for this soil ,and though to know how could we use this soil and where it could work and the amount of compaction needs of the soil containing a different amounts of water contents , to get the last conclusion from this important experiment , which is that the moisture content determination in the in situ in all field project is from the most important things that getting me ready to know the method of foundation thatà ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢s need above this soil to build on it at the end , stable , strong and good structure on it . In biological applications there can also be a distinction between physisorbed water and free water à ¢Ã¢â‚¬Å¡Ã‚ ¬ the physisorbed water being that closely associated with and relatively difficult to remove from a biological material. The method used to determine water content may affect whether water present in this form is accounted for. For a better indication of free and bound water, the  water activity  of a material should be considered. Water molecules may also be present in materials closely associated with individual molecules, as water of crystallization, or as water molecules which are static components of protein structure. In conclusion , Knowing the amount of moisture content of a substance helps determining if the soil is suitable for a specific use. Such like:- To know if the soil can hold structure safely for long time safely and serviceability or not. To be able and ready for the design of the foundation of any type of the structures. Determining and controlling the moisture in substances is unique and necessary for many products, and the process borders between art and science , in many and variable sides of the life and nature knowing how the Soil water regulates soil temperature by different amounts and shape of moisture content. Soil water serves as a solvent and carrier of food nutrients for plant growth. Tools , equipments and specimens Equipments that we have use in the laboratory for the moisture content determination experiment : Soil container : Ità ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢s a container which is ceramic containers of various shapes on light wood background Stock Photo 8282849 used to put different types of soil inside it or a combined types with others in the same container , and we have used it in this experiment to put a random type of fine-grained soil inside it and mix it with to determine the wight of it , and actually Soil container there are many sizes of the soil container upon to the quantity of soil need to put it in the container. IMG_0212.JPG SpatulaSpatula : it is an aluminum thin tool use to put soil by it in the soil container and for mixing the soil and water with each other in the soil container and also ità ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢s used for transfering soil from container and put it into heat resistance pot which is made of steel. IMG_0209.JPG Steel ContainerSteel Container : it is a container made of steel that have a heat resistance quality , which used to put the moist (wet) sample of soil inside it , to put the moist sample then inside the oven to dry the sample of the soil. Digital Balance : is the instrument use to weigh the different things , that not have an enormous weights , and it used in this experiment to weigh the soil container alone once , and to weight the soil container with soil inside it then. Digital Balance http://www.supplierlist.com/photo_images/167132/Vacuum_Drying_Oven.jpg Oven DryOven Dry : it is an apparatus used to heat the specimens needs to heat in the laboratories , and it was used in this experiment to dry the moist sample of soil. moist soil sample : the wet soil > Dry soil sample : the dry soil sample before putting in the oven sample after putting in the ovenIMG_0209.JPGIMG_0211.JPG Moist Soil Sample Dry soil sample Background Based on the literature review, the feasibility of using microwave oven to determine moisture content of soils is well demonstrated. In addition to the GS, there is an available international standard test method (ASTM D4643) for such determination. This method includes requirements to control the power ratings of microwave ovens and the period of drying procedure. Therefore, the possibility of overheating of a soil sample can be greatly reduced. In addition, the soil sample is required to be carefully mixed after each time of ovens heating for a certain period in order to prevent non-uniform heating of the sample. And in this experiment we going to compute the moisture content using this test method method be determine the weight of the soil before and after the dry process by the laboratory oven dry ,and then compute by a dramatically series of calculations the amount of moisture content in that sample of soil given in the laboratory. Procedures According to ASTM 2216, the dry and clean container should be weighted using balance and its mass recorded. A representative sample should be selected . The moist representative sample should be placed in the container. The lid should be secured in its position. The mass of the container with the sample should be taken and recorded. The lid should be removed and specimen should be placed in the oven. The sample should be dried in the oven at. The container should be removed from the oven when the sample reach a constant weight which means all the water has been evaporated. The specimen should be weighted and recorded. The moisture content then calculated by a series of calculations , and below in the next paragraph , all of the data and calculations is explained preefly by a list of numbers.

Times  in construction  we often need soil that must be suitable for building. In some cases  the soil  there and depending on where the land is located,  the soil  may not hold  foundation of  a building well.  In order for us to find out if  the soil  is durable enough to hold the  foundation of  a building we might have  to measure  the  moisture  of the content. When the percent of water is found we can than choose of  the soil  is suitable enough for the  foundation of  the building. actully the most important thing we have concluded from the experiment of determining the moisture content in the soil , is to know how much amount of compaction needs for this soil under the foundation to held the structure safely. Actully all foundations (including abutment) surfaces shall be shaped one horizontal to one vertical or flatter except as otherwise specified.And after stripping (due to stripping specification), the foundation shall be loosened thoroughly by scarifying or plowing to a minimum depth of six inches. The foundation shall then be compacted to the density and moisture requirements specified for the fill Areas that are too low after stripping and shaping must be filled to base grade with compacted fill equal to that used in other parts of the project, and eventhough the moisture content determination is from the most important tests that is from the basics we need in the Geo-technichal engineering, and later on in the foundation design. Conclusion The result of water content we get in the experiment after quit dry of the sample in the oven dry was 8.1% which is not acceptable to be able for building over it. Ità ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢s quite high for fine grain. This means ità ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢s not safe to build a structure, because the maximum allowable water content for grain is 1 %. Also this experiment is very important in Civil Engineering. Before construction ità ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢s very obligatory to know the water content of the soil. If the water content is very high and construction is done, that might cause damage to structure which will appear later. Actully , for each type of soil has its own capacity to keep the structure safe. For example, If the sample is coarse the maximum allowable water content is 6%. While for fine its 1% , so the last result we get from the determination of the moisture contents in this soil is that , with this high amount of moisture content we can not use this soid for the construction purposes , and if we try to do , it will cause a big proplems and damage in the building later in the future and will neve ever by safety to use it in the civil society. Type of errors Personal errors:- Personal errors such as mistakes in reading from the balance , or mistakes done by wrong transferring data to the data sheet ,also the delaying of time taking out sample from oven it can cause error. Instrumental errors:- Errors might occur in digital balance due to the amount of accuracy of the digital balance. The reading also will change because of air condition. To eliminate such type of errors the reading should be taken several times. Environmental errors:- Moisture in lab and air of air condition can cause errors in readings , and though will not give us the absolute amount of moisture content , and the temperature in the laboratory affecting the sample of soil and instruments in the lab , all of these invironmental factors could give us wrong readings in the esperiment.
