Different Family Values Between China and America

The family education is related to a person†s life. Nowadays, social development needs high qualified talents and good family education is the key point to the high qualified talents. Because of the different social systems, culture backgrounds, education aims and so on, family education for the children is different in many aspects between China and America. In the education projects of training new century talents in the world, all the countries put family education in a very important position.Although family education now attracts social circles’ attention, especially educational circles’ attention, Chinese family education still had a lot of problems. This paper first introduces the definition of family education. Second, this paper points out the main problems in today’s Chinese family education. Third, by comparing, this paper points out the different family education between China and America (mainly on aspects of family education’s contents, aims and methods). Family education aims for training the children into what kind of person that the education contents and methods choose according to the aims. After comparison, the paper interprets the reasons of these differences. Finally, the paper puts forward some methods that suit Chinese family education. [Key Words] family education; comparison; American; Chinese 1. Introduction Entering twenty-first century, as one of the hottest spot, family education is becoming more and more important in people’s life. Family, as the cell of society, is the first place that children receive education and the first unit that the children get in touch with the society. Education is a highly complicated process which is connected with families, schools and society throughout one’s whole life. A modern society, whether it can present its special education function, which is already the base of the power to push the society and creation of family happiness. In modern society, family education contents become various, it includes not only family life education, family relation education, family morality education, but also children education, parents education and so on. In this paper, I will discuss the education of the children.2.The definition of family education â€Å" Harry Chester’s Schools for Children and Institutes for Adults (1860) says, ‘Education is the development and training of the human being in all his capacities, spiritual, intellectual and physical†¦Ã¢â‚¬â„¢Ã¢â‚¬ [1]P148 In the dictionary, the definition of family education explained in this way: Parents or elder generation educate the child or teenage in family. Different society needs different family education. â€Å"Zheng Qilong, in his work family education, explained it in another way: Education is a society use to educate new generation with aims and systems†¦Ã¢â‚¬ [2]P6-7 Family education is parents educate their children, it is an important part of t he whole education system.For the sake of the changing situation, the definition of family education should be extended: â€Å"(i) Family education is not only the action of family but concerns the whole society. (ii) Family education’s aims are not only studying the family relation and living skills, but also the physiology and psychology of every family member and family members all-round development. (iii) Family education is not only the way that parents or elder generation educate the child or teenage in family, but all the family members educate each other. (iv) Family education is not only the education of the pre-school education, but also all life education.†[3]P523.Main problems in today’s Chinese family education 3.1 Parents’ mistake in conception of value and wrong activities leading A child’s conception of morality and value orientation learns from acquistion, especially from his parents. So parents affect the child’s mind great ly.â€Å"(i) If parents always say some positive view, such as, ‘Money makes the mare go’ or ‘Money talks.’†[4]P23 The child may form a conception that people live in order to make money which is a wrong view of value. (ii) Parents sometimes endorse some wrong behaviors, the child may form an idea that those wrong behaviors are right. 3.2 Utopian expectation of children’s educationChinese parents produce a great impact on children’s future. When a baby born in a Chinese family, his parents often design a future for him, no matter the child likes it or not. That is to say, Chinese parents would enforce their children living under the designed future instead of considering children’s feelings and abilities. â€Å"Just as Phierbaha says ‘Parents’ biggest  false is they stand in their position and interfere children’s nature development.’†[5]P24 In China, we can find the following scenes easily: Pa rents take their children to various kinds of lessons after school. Children would be punished if they didn’t get a good mark in examinations. 3.3 Harmful types of family education3.3.1 A utocratic type of family education In some Chinese families, parents require their children should do whatever they want their children do. If the children didn’t do as their order, they will scold the children, even worse, they will punish the children. â€Å"A questionnaire of 300 students in a middle school shows: Ninety percent of the students had been punished!† [6]P24. They can’t bear that children did’t obey them. They restrict their children. They check their children’s cellphone. 3.3.2 Indulgent type of family educationParents’ love is very important for the psychology development of teenagers. However, in modern China, a child is probably the only child in a family, and parents give too much love to the child. It leads to a situation that t he child can’t live without their parents. They seldom run into troubles because their parents had already solved the problem for them before they meet the problem. This kind of children can’t get along with other people very well. They consider themselves as the most important ones. Even worse, they may not have enough independent ability to live in the society without their parents’ help. When they go to society, they will feel depressed. â€Å"In a investigation of 4000 youth criminals, 16.3% of them receive this kind of family education. †3.3.3 Careless type of family education It usually refers to parents who lack of responsibility to take care of their children. Young parents are working hard to make money. They don’t have enough time to get along with their children. According to a survey, the children whose parents are individual entrepreneur, taxi driver or labor contractor, break the law easily. The main reason is the parents mentioned ab ove, who have few time at home. Even they are at home, they seldom put their hearts on their children. They simply think if they provides a good living condition for their children, who will become a talent. This type of  family education is dangerous. Children’s thought is not mature enough to judge all the things in a right way. It is easy for children to choose the wrong way to go.3.3.4 Changeable type of family educationThe children had been influenced greatly by this type of family education. For parents, the way to present this kind of education is self-contradictory. In other words, one parent is severe, another indulgent. Or the same behavior, is allowed today, but is forbidden tomorrow. A great number of research proved that children’s behaviors have a close connection with the changeable type of family education when they are young.3.4 Bringing up by elder generation show more disadvantagesBringing up by elder generation means more chance to spoil the child ren. The popular situation is that children raised by grand-parents. In this way, there are more disadvantages than advantages. Grand-parents used the traditional view to teach their grand-sons or grand-daughters. The result of this will destroy the children. 4.Main problems in today’s American family education4.1 Indulgent type of family education Different from Chinese family education, Ameirican indulgent type of family education had more harmful effection. Because over indulgent, it made a lot of social problems.Such as, teenage crime. In radio or TV, we sometimes can get a information that a 15-year-old boy shot his friend in the middle school.4.2 lack of communicationAmerican think that every member in a family, he or she should had his or her own space. In their opinions, they can†t interfere each other even they are in a family. And when a person is 18 years old, he may leave his parents. It means his has little time to stay with their parents. So they has less resbosibility to their parents. But, in Chinese people’eyes, it’s no a good idea to leave their parents. It may lose the chances to communicate with each other.4.3 pay too much attention on happy learningAmerican take happy learning serious. But, in fact, happy learning is good when children are young. Only pay attention to happy, parents may find that children’s learning levels are declined. For example, some students who get used to happy learning, can’t calculate without calculator.5.The comparison of the family education’s process between China and America From the results of the family education, we can find, in the process of family education, although it is not a kind of systematic education, it still has its educational aims, contents and methods, like the schools, which play an important role in the educational system. The aims of education are the most important ones which determine family education’s contents and methods.5.1 The c omparison of the contents of family educationThe aim of education determines the content of education. â€Å"The contents of American family education are very plentiful. American parents pay attention to their children’s all-round study.† We called â€Å"qualified education†,which includes physical strength, cognition, social ability, emotion and so on. To enhance children’s physical strength, children do outdoor exercises, such as, playing on a swing, hiking. On the development of cognition, parents train children’s sense organs, enlarging their culture view and hobby. For example, when parents go to library for study or borrow some books, they always take their children with them. In this way, they can stimulate children’s interest. On the development of social ability, children are required to enjoy themselves and share things with their friends. On the development of emotion, with the help of the parents, children learn to enjoy music, art or dancing etc.Although the contents of Chinese family education are divided into morality, intelligence, physical, art etc. However, when the child at school age, intelligence is the most important. The contents of education become imbalance. In physical, Chinese parents pay more attention to children’s nutrition, they make great effects to prevent their children from diseases. Compared with American parents, this kind of education is a protection which is defensible, static and passive. Greenhouse-training can train a person strong; On intelligence, children are given knowledge, skills, such as, the books that are full of knowledge and interesting things, at the same time, they learn the skills of reading, writing and counting.When the children begin their school  education, family education are inclined to the tendency of school education: parents supervise children’s study, check their homework, buy extracurricular exercises for the children. On art education , more and more parents realize the important professional skills. So they request children to learn drawing, dancing without children’s willingness. It is a blind action, it may kill children’s talent, even worse, they may pay a good deal of money and a lot of time but without good results. And doing this willgive too much pressure to children. By comparison, American family education’s contents are substantial and scientific. On the contrary, Chinese family education’s contents are narrow, limited and not scientific. For example, in Chinese family education, physical is less important than intelligence.Chinese parents pay more attention on children’s health from which is the low-level content. Children ignore physical training, lack of outdoor exercises, stay at home to watch television. Then the number of getting adiposity become larger. Intelligence includes practical ability and latent capacity. Practical ability is what you know, what skills and knowledge you should master. Chinese family education always ignore skills, such as, living skill, working skill, communicative skill etc. American people take these skills seriously instead of ignoring them. In their opinion, these skills are the basic quality to stand on the social stage.Chinese family education ignore not only some practical abilities, but also latent capacities which are divided into study ability and creativity. Chinese parents seem to think highly of knowledge study, in fact, they only pay attention to the low-level knowledge which just can deal with school examinations. In a questionnaire called â€Å"how to train teenagers’ creative ability.† There is a question , â€Å"If you find your children trying to take a clock apart, what will you do?† 40% of parents will scold the children. 48% of parents will use a way without patience.From this questionnaire, we can find out Chinese parents’ ideas of training creation should be impr oved.By comparison, American parents pay attention to children’s multi-hobby and creation-consciousness training. Most American experts adviced that not to learn knowledge without comprehension study. When children come back home from school, Chinese parents always ask a question â€Å"Do you remember what the teacher teach?† or â€Å"Do you get a good mark on today’s test?† Yet, American parents will ask â€Å"Do you ask teacher some questions?† or â€Å"Is the lesson  interesting today?† This present the different opinions on intelligence between Chinese parents and American parents. 5.2 The comparison of the aims of family educationFamily education’s aims determine it’s direction. So the aims of family education are the core, which is the basic reason of the different family education between Chinese and American. Family education’s aim is to train a child with some characteristics through family education. Once the aim is determined, education contents and methods should be chosen according to the aims. So what’s the different aims of Chinese family education and American family education, or we can say the different expectations of the parents in the two countries.American family education’s aims are to train the child into a social man, who can deal with all kinds of events and own independent ability. It is not a high expectation. â€Å"Social man† is not an utopia idea, but a requirement which is practical and easy to achieve. So American parents have a relaxed attitude to educate their children. They are good at finding out the active parts from their children’s individuality. And the children can find their value from family education. In fact, this kind of education can achieve good results.According to this aim, they can train their children’s independent ability. Let’s see American children in different periods. When they are still a baby, th ey sleep alone; When they can walk by themselves, they seldom ask parents for help; When they grow up, they own their rooms and they should clean the rooms by themselves; They do what they can do from childhood to make money. For example, they do house cleaning, be a baby sitter, send newspapers; When they go to senior middle school or university, they do part-time jobs to make money for the cost of living. By comparison, Chinese family education’s aim is to train the child into a talent, who has a bright future. A bright future means to get a good job and to lead a simple life all their life time.First, this aim is high and full of utility. It is hard to achieve, because â€Å"having a bright future† is not an ordinary aim. Because of the aim, Chinese parents especially concern about children’s study achievements. Their only requirement is that their children can concentrate all the attentions on study. At the same time, they ignore their children’s extr aordinary abilities, damage their imaginations. At the end, parents would kill the talents before the children  become qualified persons. Although Chinese children study very hard, and get good achievements. They lack of abilities to suit this society. Sometimes, parents’ expectation would come to nothing.5.3 The comparison of the methods of family educationThe methods of family education are the concrete measure of education contents. The choices of which education methods are connected closely to a nation’s custom, culture and history. At the same time, it is restricted by education aims. Conversely, whether the parents can use the scientific education methods properly is connected to the realization of family education’s aims and contents. Generally speaking, in American families, â€Å"parents mainly use an equal way to educate their children.They respect children’s personality and rights. Children, in the family, are treated as independent individ uals. Parents and children are equal.†By comparison, Chinese family education’s methods lack of equality. Chinese parents don’t treat their children on the same level as themslves. Instead, parents stand for the elder generation and the children stand for younger generation. American parents advocate the open education:First, they pay attention to practical training, emphasis on training children in practice instead of preaching. In American’s opinion, if the children can do the work, let them do it. Through the process of doing the work, they can improve their recognition of things, accumulate experiences, master skills, enhance capacities, develop hobbies and consolidate self-confidence and responsibility. We can say, American parents give the key of the door to children instead of opening the door for the children.Second, American parents think play and game are very important. They think play is the most important thing when children are young. In Amer ican, children take part in all kinds of activities, do a lot of outdoor exercises. There are a lot of good places for them to do exercises. On the weekend, parents go out for tour with children. In the process of playing, the children develop their intelligence, such as imagination, judgement, communication with other people and emotion adjusting and so on.. Chinese parents advocate the close education:First, they ignore the importance of practical training, instead they pay attention to preaching. The requirement to children is study. All the things, including what the children can do by themselves, are done by their parents. It is the reason why Chinese children learn a lot of knowledge but can hardly do anything when they enter the society. Second, they lack of outdoor exercises because Chinese children have endless homework. They live under the pressure of a lot of examinations. At the same time, they can’t find a good place to do outdoor exercises. Because of different education types, American family education and Chinese family education show different methods. So, we can try to turn our close education into open education. American family education methods present in four aspects:First, children have their right to speak, in other words, they can show their opinions on family affairs. American parents inspire their children to say what they want to say . Second, American children have right to choose, when the children start to show their ability to cognize things, they would like the children to choose by themselves. The children can choose games, books, friends, jobs and so on. American parents wouldn’t put their opinions on their children. Most of the time, their role is to lead the children to choose, or they only stand behind the children, to give them confidence.Third, American parents can make friends with their children, they can communicate on the base of equality. Fourth, American parents respect children’s rights of pri vacy. Chinese family education methods also present in four aspects: First, children have less right to speak, that is to say, Chinese parents require their children to obey the rules, and have few different ideas. As the American president Nixon said â€Å"The task of Chinese education system is to train children into a person who is docile, completely listen to elder generation. In this way, they lose Chinese Darwin and Einstein.†Second, Chinese children have limited right to choose and most of them would like to do things according to parents’ willingness. Third, Chinese parents always appear with a image of authority so their status are higher than their children at home. Fourth, Chinese parents always destroy children’s rights of privacy. For example , their school bags are searched; diaries are peeked. We can find that differet family education methods present in different aspects. American pay attention to the right  children own, but Chinese never thin k so. The democratic method of education which is a kind of loose and comfortable education, and presents a great deal of advantages: For one thing, it helps to train creative ideas. Loose and comfortable conditions are the most important to stimulate children’s creativities.Under high pressure, children’s creative ideas would be constrained. On the contrary, in a happy and calm family atmosphere, children can be stimulated easily. To produce a loose and comfortable atmosphere, parents should build a relationship equalled with children. For another, it helps to form healthy personality. Children would take part in family affairs actively, to express their own opinions, stop being afraid, and be full of self-confidence and responsibility if they are given the rights of speaking, attending and choosing. In addition, this kind of relation can inspire children to share their secrets to their parents. At the same time, parents can understand children’s thoughts. It u rges children to form a good personality. However, autocratic method of education presents a kind of restrained education, which constrains creation and the development of personality.6.The comparison of the family education†s results between China and America Different results of education are due to different contents, aims and methods, which can be discovered after comparison . Generally speaking, American children show distinguishing features when they are very young. For example, they show great enthusiasm, keep calm when they run into troubles, get on well with other people, have great power and are full of new ideas, strong independent ability and social ability. Because they are independent from parents when they are 18, they are full of more confidence and courage.Further more, they should do part-time jobs to meet their needs of money. Having the idea of suiting market economy, they take part in money management, at the same time, they learn how to promote sales and communicate with customers. They realize money is not easily earned by all these kinds of practice. Thus, they get into a habit of thrift. In a word, the outstanding characteristics of American children are their great abilities and the adaption to the society smoothly. However, Chinese children, teenagers, even university students, who do well in their studies, show negative tendency in their characteristics. In more details, they  behave in a passive way, such as timid, having deep-rooted dependent mentality, lacking of the ability to communicate with other people.Even worse, with poor independent viability, they can’t deal with money in a proper way. In short, they are lack of the ability to adapt to the society. All of these characteristics, which can be found from Chinese children, are due to Chinese â€Å"diploma-education†. Chinese parents expect their children to study hard in the school instead of taking part in the changeable society. Nowadays, what kind of the education results fits the society? Social development needs man’s activity, creativity and humanity’s liberation.As the civilization develops, more and more people need to focus on the development of humanity and the ability to do all kinds of things. So we can say today’s society needs active and all-round talents. Obviously, American family education can train a child, who is full of creativity and capability, by comparison, Chinese family education only can produce a â€Å"talent†, who is good at studying and obeying the rules. It is the result of â€Å"examination-center-education†, which can do harm to our teenagers’ body and mind. So Chinese family education needs a reform immediately.7.The causes of family education’s differences between China and America In modern society, parents take education seriously in Amreican the same as those in China. Why these two kinds of family education have so many differences? To sum up, the causes of different education are:7.1 The different history backgroundsAmerican, which is an emigrant country with a short history, has less old culture. Affected by multi-culture and multi-value, it can accept new thoughts and culture more quickly without restriction. So compared with Chinese people, they possess more adventure and creation sprits. However, China had a long history, at the same time, it reserves more old culture, especially is affected by feudal farmer’s idea for a long period. Its culture value is conservative and cautious, which lacks of adventure spirits and creation consciousness. Chinese people are educated to be obedient, comparative and lack of an environment to accept new ideas on the whole.7.2 The different economic patternsAmerican productive force is advanced. Its commodity economy is flourishing. There are a lot of opportunity to get jobs. The pressure of living are limited. Moreover, The United States is a society of capabilities, where the system of is perfect, staff are free. And they have a lot of opportunities of changing a job. It means there are various of jobs for Americans to choose. In American parents’ opinions if children can base themselves on the society, no matter the job is highly valued or not. Besides, commodity economy is changing in every minute, jobs are changing too. So parents never think their children can live a smooth life.Consequently, American family education’s aim is to focus on training children into â€Å"human† It seems more macroscopic and wide-ranged. It meets all changes by remaining unchanged. By contrast, â€Å"China is a developing country. The pressure of living is great. China is a society of diplomas. Jobs are stable, so Chinese always put all their happiness on a job. Their choosing are limited. Chinese parents think good study achievement can bring a good job for their children. It is a smooth way of life, and it is also the best way for a person.† Therefore, Chinese family education’s aim is to focus on training children into â€Å"talents†.7.3 The different social conditionsAmerican have good economic conditions, perfect old-age social system. American parents don’t have the idea that rearing children against old age. Instead, they think when they become old, they can go to old people’s home to live the rest of their life. So they rear the children to 18 years old, who become independent persons, and they finish their jobs without considering what the children will be in the future. They don’t care about whether the children will bring honor to them or not.By comparison, China, a nation which economic condition is poor, has incomplete social old-age system, and exists some old conception questions. Chinese parents consider that children’s education is connected with the rest of their life. They treat the children as their own property, require children to pay back for them. And the t hing that presents it in their ways is education. Many Chinese parents treat the thing of beating children as a personal affair. They think no one can interfere,let alone the law. 7.4 The different traditional cultures7.4.1 Different value orientationsAmericans pay attention to personality, their value orientation is based on the individualism. They lay stress on their own benefits, advocate individual improvement and find their own true value. It is the core of American culture. An American scholar pointed out: In a democratic society, every citizen has his own goal, which is himself. In the family, individual is the most basic one, which is the valuable, independent from his family relation and doesn’t depend on others. So in American family, parents used to treat themselves and their children as two separate individual. â€Å"Self† doesn’t only include parents themselves but the children selves. To carry out children’s self-value, parents should respec t children’s willingness, interest and hobby first. But American parents attach importance to enjoying their life.They wouldn’t give up to go to cinema because of the children. Chinese pay attention to general character. They have a conception, which is the most important. The conception is collective spirit. In other words, it means considering things as a whole. It emphasizes collective interest more important than individual interest. Chinese consider that a person is living in contrast with other people. From ancient time to the present, â€Å"self†, this conception results from contrast with other people, that is, individual value only can live with others’ relations in Chinese society. In Chinese family, parents lose themselves at the same time, they don’t respect their children.â€Å"The way that Chinese parents lose themselves presents as following: they consider children as their own, as a continuation of themselves; their children seems to be their whole lives and hopes; they put all their hopes on their children. This kind of parents would use their determination to replace their children’s.†[10] P62 They think from adult’s view. So we can find Chinese parents always set an impractical goal for their children. American pay attention to personality while Chinese pay attention to general character. It has its economic background. In the structure of modern capitalism, American’s commodity economy defeated nature economy. And it exists for more than a hundred years. In the condition of commodity economy, individual is independent relatively. One person, if he wants to develop in the competition of commodity economy, he must improve himself.Therefore, in the commodity economy society, people keep a tradition which is to value self the most important. By comparison,  Chinese’s nature economy existed for thousands of years. Chinese are get used to tying on the land. Individuals lack o f the condition of developing by themselves. Through dozens of years planned economy, even more than twenty years of market economy, Chinese can’t get rid of the dependency. Individual’s development often need other people’s help. Even evaluating an individual is carried out by comparing with other persons. So Chinese like taking part in community, in order not to be isolated. å’Å'Americans encourage rationalism. Their family education praise rationalism highly, which they treat as a basic principle to deal with family members and family affairs. Most of American parents consider the obligation of raising a child the same as the obligation to the society. It does stand not only in an individual position but the social position. In Americans’ opinions family education is considered as an obligation, so Americans never want to get something back from their children. They consider that they ought to go to the old people’s home. Of course, it is bas ed on American perfect social security system and their culture.Chinese encourage affection which is considered to be the most important thing in Chinese society. Chinese family education, human relation is the base and emotion is the rule to deal with the relation of family. Chinese parents consider the children as their own private property, from the angle of their honor. Chinese parents take the greatest care of their children but with a conception of getting back something from their children. From this point of view, we can understand why more Chinese parents expect their children to be talented than American parents does. They put too much material gain in the aim of family education.8 Suggestions This paper is comparing the vague generalization of family education between China and America. Chinese family education and American family education have their own characteristics. Furthermore, American family education has its disadvantage either. Apparently, the paper doesnâ€⠄¢t aim at denying American family education or Chinese family education. Through the comparison, this paper puts forward some suggestions that suit for Chinese family education.8.1 For education aims: turn â€Å"talent† education into  Ã¢â‚¬Å"human† education. Through the comparison, we can find, American family education’s aim more fits the development of society. At the same time, it can produce more creative persons. We can’t deny, in Chinese examination education, we kill a lot of talents .If we want to change the situation, we need family education’s help. Generally speaking ,as the enhance of social productive force, the society competition becomes more and more fierce. A person’s comprehensive quality becomes more and more important. In fact, this comprehensive quality is the basic human education. Using human education as our family education’s aim, Chinese will get rid of the mistaken ideas of family education.8.2 For educa tion contents: â€Å"turn ‘one-sided’ family education into ‘all-round’ family education. Today’s aim of family education is to teach intelligent knowledge. Because of the wrong aim, the intelligent education is the most important. This kind of education, will make children’s quality development unbalanced so that they can’t fit for this changeable society. After setting up â€Å"human† education as our family education’s aim, parents should improve children’s comprehensive quality. If we want to improve children’s comprehensive quality, we should turn one-sided family education into all-round family education, especially education of latent energy, morality and temper.8.3 For education methods: turn â€Å"restrained† education into â€Å"loose and comfortable† education, turn â€Å"closed† education into â€Å"open† education. Affected by Chinese culture, parents have more power than democracy. This kind of education is harmful for teenagers’ mature. Modern society should advocate loose and comfortable education and open education. 8.4 To set up a conception of qualified educationNowadays, education reform’s core is to improve education’s quality. â€Å"The main aim of education is to teach children to learn from how to live to care other people then responsible for others.† Concerning to family education, parents should set up a conception of qualified education. Qualified education is based on human’s physiology and psychology, which has nature peculiarity. It is a kind of education that can train teenagers all-round development. Furthermore, its goal is to fit the needs of the society’s development.Through qualified education, parents teach the youth playing, working and communicating which are the abilities a person should  own in modern society. Quality education aims to improve every aspect of quality a tale nt needs. It is not only a conception of qualified education but also a conception of value. Only when the parents set up the conception and use it as family education’s guide, can the children get used to this society quickly and smoothly. 8.5 To turn sole education into multiple educationIn Chinese, many parents aim the goal of education on intellective education. So they ignore non-intellective education which concerns children’s physiology health. Scientific family education should give first place to intellective education and in addition, take care of children’s physiology, psychology, knowledge. Besides, parents not only teach the children knowledge of culture, which is necessary in a person’s life, but teach other kinds of knowledge. Although to increasing knowledge of culture does good to intellective development, it is not sure it helps a lot.8.6 To turn knowledge education into capability educationIn today’s society, development of moder n science has put training ability in a higher position than teaching knowledge. Family education demands the parents not only to give children food but the skills to get food. Chinese should change the method which focuses on the knowledge, turn knowledge education into capability education. Ability is the intelligence that people finish a task or achieve their goals It is the result of psychology condition and physiology condition. It includes intelligence skill system, motivation structure system and operating skill system. These three systems connect with each other and inspire one by one. A person’s development level depends on the whole ability system which is formed by them.8.7 To use scientific mode of family education to speed the refrom of family education8.7.1 Creative type of educationâ€Å" This kind of education pays close attention to the development of children’s latent energy, which fixes eyes upon the use and training of intelligence. It advocates on creative study through active research and self improvement. â€Å"The basic education mode is: cognition-research-creation-application, which is people’s ability of  acquiring and using knowledge, and the wisdom that people show.† It includes observing ability, memorial ability, thinking ability, practical ability and so on. These abilities connect with each other and restrict each other. They are always considered as a whole. So intelligent education depends on all of the abilities mentioned above.8.7.2 Successful type of educationIt aims at creating the condition of success.

Children’s character and destiny are connected closely to family education. For the family, for the children, for the parents, we should change the wrong conception of family education and correct it at once.We, Chinese, should change utopian expectation of  children’s education.

To use scientific mode of family education to speed the refrom of family education. If we can follow these changing, Chinese family education will go to a bright future. Ameircan also can get something they lack of from our family education.

Dr. Pepper Snapple Group Case Study Essay

1. HOW WOULD YOU CHARACTERIZE THE ENERGY BEVERAGE CATEGORY, COMPETITORS, CHANNELS, AND DPSG’S CATEGORY PARTICIPATION IN LATE 2007?_ In late 2007 the energy beverage category was reaching market maturity and projected to have a slower annual growth rate from 2007 to 2011 (10.5%) than it had between 2001 and 2006 (42.5%). Rising prices, packaging competition, and the introduction of hybrid energy beverages also added to the slower projected growth rate. However in 2007 the market still saw growth of 32%. The category is dominated by 5 major brands (94% of dollar sales), with Red Bull far above the pack with a 43% dollar sales market share. The other 4 are in close competitions with dollar sales market shares from 10-16%. Though Red Bull continues to grow, so does the competition. New, aggressive competition into the market and brands offering lower prices has brought Red Bull’s market share down from 82% in 2000 to 43% in 2007. This 43% of dollar sales is maintained with only a 30% share of unit case volume. Because of loyalty to Red Bull, consumers pay a premium price for its products. Red Bull’s 8.5 oz. cans sell for the same price (approx. $2.00) as many competitors’ 16 oz. cans and their 16 oz. can sells for around $3.50. This loyalty puts Red Bull far above other brands and leaves them to compete with each other on price and packaging. Pepsi and Rockstar are not projected to have any significant media expenditures in 2007, but Red Bull and Hansen Natural Corporation are projected to increase their media expenditures to $60.9 Million (from $39.6M) and $153,800 (from $61,100) respectively. Once again, it is clear to see the major difference between Red Bull and the rest of the group. Coca-Cola (Full-Throttle, Tab) is projected to decrease its media expenditure from $7.3 million to $492K, which is still more than Hansen, but far from the expenditure that Red Bull maintains. Off-premise retailers represent 71% of total retail dollar sales compared to 29% for on-premise retailers. Off-premise retail sales are dominated by convenience stores (74%), but the off-premise retailers are slowly evolving. Convenience stores are slowly decreasing in percentage of sales, while sales  in supermarkets and Wal-Mart are growing. Brands with broad product lines, multi-packs, and widespread distribution networks are succeeding in supermarkets and stores like Wal-Mart. In convenience stores, brands with smaller product lines and high inventory turnover, are gaining success. Restaurants, night clubs, and other on-premise retailers remain constant and are not projected to have any significant changes. In 2007 DPSG began setting up distribution channels, which were projected to reach 80% of its target market by early 2008. It also began distributing Monster energy drinks on behalf of Hansen. DPSG also participated in the U.S. Sports Drink market in late 2007 with its launch of Accelerade RTD. Using its distribution network, DPSG introduced Accelerade to convenience stores, supermarkets, and mass merchandisers. It targeted the $35 million Americans who were competitive and exercise regularly. It supported the launch with a large marketing budget which consisted of a web site, podcasts, search-engine marketing, and a chat room. It emphasized the protein content to differentiate itself from the competition. _2. DOES YOUR CHARACTERIZATION BODE WELL FOR A NEW ENERGY BEVERAGE BRAND INTRODUCTION GENERALLY AND FOR DPSG, INC. IN PARTICULAR?_ Generally it does not bode well for the introduction of a new energy beverage brand but in Dr. Pepper Snapple Group’s case, they may have the brand loyalty, budget, and awareness to pull it off. With a large market share and huge media budget, Red Bull makes it difficult for new brands to compete. Unless a brand is willing to spend a large amount of cash on R&D, media expenditures and competitively price its product to give incentive for consumers to switch from Monster or one of the other brands, it would not gain enough of the market share to compete. Red Bull is in a league of its own so new entries would mostly be competing with Monster, Full-Throttle, Tab, Rockstar, and numerous other less popular brands. DPSG on the other hand has the brand loyalty, equity, image, and budget to support such a venture. It also has some unique qualities such as the addition of protein, a larger, re-sealable bottle, and an emphasis on performance over simply something to perk the consumer up. Since DPSG already has a target market,  distribution network, and manufacturing set up, it could feasibly enter the market on the shoulders of its good name. The fact that DPSG has differentiated itself from the other brands also gives them a leg up. If it could successfully attract more consumers from the 35-54 year old range by riding its healthy image and promoting a healthier, more fulfilling energy beverage, it could that target market and become a great competitor. _3. WHAT TARGET CONSUMER MARKET SHOULD BE CHOSEN FOR A NEW ENERGY BEVERAGE BRAND?_ An opportunity lies in the 35-54 year old range. It is a market that does not receive much attention and is not specifically targeted. Since this target market consumes only slightly less than the 24 and under market, there is a great opportunity to promote a product that suits their needs and advertisements that speak to them. By capturing that market, DPSG will stay consistent with its brand image and give it the awareness and experience to begin transitioning into the 12-34 year old market in the future. After 35, many men and women begin to exercise harder, and more often to maintain their youth as much as they can. If DPSG can provide a happy medium between a sugary energy drink and a full-fledged protein shake, they could help the 35+ consumers feel younger, while still giving them beneficial ingredients that their bodies need. _4. WHAT PRODUCT SHOULD BE INTRODUCED AND HOW SHOULD IT BE POSITIONED/DIFFERENTIATED?_ Considering DPSG’s brand image, I think its best bet would be to introduce a low carb, low sugar, protein infused energy tea. Since the earliest civilizations, teas have been used for their various health benefits and today is no different. If they target the 35-54 market, a tea would be much more attractive than a sugary, carbonated beverage. Since Snapple has such a good name in today’s marketplace, especially with adults, I believe the drink should be branded under the Snapple name. As of right now, Snapple’s most popular flavors out of all its products are Lemon Tea and Peach Tea. DPSG could parlay that popularity into an energy tea by adding a few  ingredients. In order to position itself in a more grown up market, differentiate itself from the competition, and stay true to its loyal customers, DPSG should introduce the energy tea an aluminum bottle with the same dimensions as its 16 oz. glass bottles. This allows it to be resealed and gives it a different look than the energy drink competition on the shelf. 4-packs could also be considered for supermarket shelves. The tea should keep with the healthy image by using vitamins, minerals, herbs, and other natural ingredients to provide sustainable energy and health benefits that other energy drinks just do not provide. Instead of focusing on providing a large energy burst, DPSG should focus on providing a youthful, energetic feeling, and restoring the body to full potential. _5. THROUGH WHICH CHANNEL(S) SHOULD A NEW ENERGY BRAND BE DISTRIBUTED?_ The new energy brand should be distributed mostly through off-premise retailers, but health conscious on-premise retailers such as subway would also be a good fit. Convenience stores are a great place to start because of the amount of exposure they provide and their track record in the energy drink market. Supermarkets are also a must because the majority of supermarket shoppers are within the target market. Whole foods would be a great place to showcase a new product to health conscious 35-54 year old adults. Also, vending machines in fitness centers and even placing fridges in sporting goods stores could attract attention from the target market. Other possible vending machine spots include golf-courses, college gymnasiums, police departments, firehouses, and airports.

Stylistic analysis Essay Example | Topics and Well Written Essays - 2500 words

Stylistic analysis - Essay Example This is not new in modern times, and it began long ago. This play talks about mans infidelity and how women can cope with it. Stylistic analysis is part of linguistics used to analyze style in language. It shows how it varies in different type of art, literature or entertainment. Author and time could be some factors that bring about variance. In writing, there are distinct styles used by each writer that differentiates him from other authors. There are also styles that are associated to a particular piece of work for example language used in newspaper or novel written by extinct Germanic authors (Gothic novel). Stylistic analysis is wide and does not have a numerical system (Jeffries 2010:1). Stylistic analysis should be able to differentiate text features, the way the reader understands them and their effects on them. Theory of foregrounding states clearly in detail and compares texts analyzed by reader with the original text. (Hoover 2007:5). According to this poem the aspects of analysis used are as follows; lexical and grammatical categories, figures of speech, repetition, Semantics, Semantic field and atmosphere. This refers to words or phrases. In this poem William Shakespeare use â€Å"Dumps, Dull, Heavy† (line 11), to show the state of women when they concentrate on mans infidelity. These Dumps, Dull, heavy can be connected to the semantic field of sorrow. â€Å"Sounds," â€Å"woe† are words that describe sorrow and sadness in women. In the play positive semantic field can be seen to illustrate positive feelings of joy as in contrary to sorrows. It is illustrated by the word â€Å"summer† (line 13). The discussed semantic fields show the internal feelings of women when faced with problems with men. This kind of feeling leads to women making tantrums all the time they suspect or learn of their men infidelity. Women’s mood is connected to use of words;

Humanities essay on historical, cultural and artistic periods of

Humanities on historical, cultural and artistic periods of origin of images - Essay Example his style and for the first time in art destroyed the space between the people viewing the art and the event covered in the painting, in this case the entombment of Christ (Gardner & Fred 67). During this period, paintings were required to remove all sorts of superstitions and lasciviousness. Paintings also lacked adornments with beauty to excite lust and everything in it was orderly. The counter0reformation period, as directed by the church, also removed profanity and indecency by ensuring that holiness was observed in the house of God. Caravaggio’s work, especially the entombment of Christ, were especially striking for their serenity and orderliness, unlike the Last Judgment by Michelangelo that came under attack from the Church (Gardner & Fred 69). This was especially so in the counter-reformation period with its nudity that was later covered with painting over it. Judgment day also contained the Charon, a pagan symbol. These symbols were completely absent during the counter-reformation era. Judgment day was also criticized for not showing a bearded Jesus Christ or a seated Christ, which was required to create orderliness and serenity in the counter-reformation era. Another painting from the reformation era that came under attack was the Last Supper that was criticized for its dwarfs, drunken Germans and extravagancy. The painting of Madame de Pompadour is an embodiment of the high Rococo style of art that shows the madam in a nonchalant demeanor, which symbolized her high standing in society. The painting is also tracing her progression to official mistress from the bourgeoisie and finally to lady-in-waiting. The book, bookcase and quill all point to a pleasure in correspondence and the arts, which was the norm in French high society at the time. Her pose, which shows her as relaxed and confident, points to her new leisure that, was also associated with French high society. The rococo style, while initially being prevalent in decorative arts also crept

Environmental Geology Research Paper Example | Topics and Well Written Essays - 1500 words

Environmental Geology - Research Paper Example In his speech delivered on June 16, 2010, the President said that we needed to break our â€Å"addiction† to oil and that will be possible when, â€Å"†¦we seize the moment.   And only if we rally together and act as one nation –- workers and entrepreneurs; scientists and citizens; the public and private sectors (Obama, 2010).† As much as I would like to see this happen, I feel that there are three fundamental realities that will prevent this oil spill in the Gulf of Mexico from becoming some sort of catalyst that will change our energy policy as a nation and as individuals. The first fact is that most American thing regionally about their citizenship, and it takes an event such as the terrorist attacks of 9/11 to really unite the nation as a whole. Americans surely feel for one another, as is shown by the volunteers that rush from all corners of the nation to clean-up after a hurricane or and earthquake. This sort of empathy, while wonderful in the most basic human sense, does little to change people’s choices. We still will build our homes in hurricane and earthquake prone areas after the mess is cleaned up. Everyone feels badly about the fishermen than are going to lose their homes and boats, but that isn’t going to make the guy driving 60 minutes each way to work to suddenly quit his job so he can burn less fuel each day. These are the choices that need to be made if we are going to become less dependant on oil, and most people won’t change because of the oil spill. The second regional issue is the economic roll oil plays in the Gulf of Mexico. The people that need to call for less oil consumption now is the residents most affected by the spill. They have the attention of the nation this summer. Unfortunately, they are not making these calls. The fact is, many are employed by oil companies in the region and the taxes generated by the oil

Dualism Research Paper Example | Topics and Well Written Essays - 2500 words

Dualism - Research Paper Example Are medical researchers within their rights to experiment on animals if their research helps cure diseases? Do animal rights properly belong to the realm of philosophy and pedagogy, or is it a matter for the courts? At the crux of the issue is the meaning of â€Å"sentience.† Does feeling (i.e. physical sensation) equate to intelligence? The main thrust of this paper is to argue that the ability to feel pain establishes a minimum ethical criterion for not experimenting on animals and, if by extension, feelings and other â€Å"emotions† are deemed to be present, then animal protection should acquire the force of law. Aristotle wrote that animals meet this minimum criterion, arguing that they are endowed with perceptive sensitivity, â€Å"which appears inherent in all animals, for they have an innate power, which (is called) sensible perception†¦Ã¢â‚¬  (Aristotle, 354). But when it came to this sensitivity, Aristotle said, not all animals are created equal. He said that â€Å"sense being inherent Name 2 in some animals, a permanency of the sensible object is engendered, but in others it is not engendered,† as would be the case with insects, for instance (Aristotle, 354). Descartes made a similar distinction, but one which drew on man’s supposedly divine nature, asserting that while animals wield an intelligence that allows them to carry out basic tasks, such as finding shelter, this intelligence â€Å"is of a significantly inferior type to the rational intelligence of man, which comes from his soul† (Kang, 117). Ultimately, Descartes decided that animal intelligence cannot be compared to that of humans, because animals are unable to reason or communicate verbally. Nevertheless, whatever the limits of animal consciousness might be, countless theories have been developed to support the validity of animal intelligence. Physicalist and Neurofunctionalist – philosophical approaches Physicalism postulates that consciousn ess canbe identified with neuron activity, a position that allows for the possibility that intelligence is a characteristic humans and animals share, so long as they are built upon the same â€Å"biological, chemical and physical† properties (Allen, 2010). Such an approach also claims that questions about the relative intelligence of different species becomes â€Å"trivial† â€Å"once neuroscientists have carried out the non-trivial task of determining the physiological basis of consciousness in animals for which no reasonable doubt of their consciousness can be entertained† (Allen, 2010). Neurofunctionalism considers the existence of neural cortex activity in primates as â€Å"the most plausible candidate for being the neural correlate of phenomenal consciousness in these species† (Allen, 2010). In â€Å"On a Confusion About a Function of Consciousness,† N. Block associates phenomenal consciousness with brain processes in certain higher-level perc eptual representations. â€Å"Since the evidence for Name 3 such processes is at least partially derived from animals, including other primates and rats, (Block’s) view is supportive of the that phenomenal consciousness is found in some nonhuman species (presumably most mammals)† (Allen, 2010). Other â€Å"first-order† theories take a more direct line, including representationalism, which insists that an animal’s ability to perceive its surroundings equates to conscious awareness. Aristotle and Locke took a

Managerial Decision Making Term Paper Example | Topics and Well Written Essays - 1500 words

Managerial Decision Making - Term Paper Example The studies that have been conducted by the bank are full of fuss, you can see that the bank is already putting a lot of money for conducting focus groups and collecting the business owners suggestions, it is all quite unusual and a big amount of risk is also involved here, the strategy that the company is applying is not a suitable one, there must be so many other alternatives for a much better data collection and analysis though it would require some more time and some human resources which would also have some investment but relatively less. The challenge is that the competitors are now quite aware of the fact that there is a new product going to be launched so they all know it and they must have also started making plans to ruin the scheme, though it is no longer remained to be an attack over competitors and most importantly the company itself can be under attack as the data collection is not very appropriate, the other challenges that might appear can be from the middlemen which in this case are people to whom the customer would bring the card and use such as the shop owners and other business owners, what they simply can do is that they can change their policies which would for sure ruin the entire scheme and also they can refuse to help the bank in their launching of such product. Another type of challenge is that the bank is unable to find the right target audience, it considers the entire population to be eligible to have this card, what should they have had done was that they should have asked their current customers to use their new product, on successful launching they would have been able to launch it nationwide, and most importantly they should try to convince each and every single departmental store or business owner as they are also unsure about which particular class uses which particular store.  Ã‚

Batman the Dark Knight (2008) and Religious Views Essay

Batman the Dark Knight (2008) and Religious Views - Essay Example Harvey Dent (Aaron Eckhart) the District Attorney is threatened by this action. Going by the situation he approaches Lt. Jim Gordon (Gary Oldman) and the Batman. As there are very little that could had been done by being within the boundary of law, Batman is asked to bring back Lau from Hong Kong. The Joker brings in a series of terrorism in the city and Batman again had to don in his black cloak and fight against the terror. Instead of following the league and reprocessing the super hero cliche, Nolan tries to depict his two archetypal characters that are the Joker and the Batman with an emphasis on religious relevance. Religious Aspect The directorial aspect of Nolan resemble with the Buddhist understanding, where the evil deeds of the movie have been shown as an effect of various adverse causes and situation. Unlike other superhero movie evil is not created out of vacuum here. In fact the joker has been portrayed as a victim of severe emotional and physical child abuse. The Distri ct attorney who is the protector of law also breaks the law of the city when he asks the Batman to do something which remains unresolved by law. The absence of good has been constructed through actions in the movie. The emergence of Two-Face in the movie reveals the dichotomy in the human nature and that no single human being is either a white character-full of virtues or a black character-full of vices, they represent shades of grey. Two-Face has also been symbolized by the fact that despite the economic crisis in the city of Gotham, the mafias and the Joker are able to keep small army of people. The movie depicts the joker as the most non- religious person and the Batman is the religious person who thinks for the good of the human kind. Respecting humanity is the essence of any religion in the world and hence Batman can be regarded as the religious character despite some controversies which does not acknowledge him as a Catholic and denotes him rather, as a Catholic who has drifte d away. A religious person is expected to follow certain rituals like paying a visit to the church. The Batman does not seem to follow these rituals and hence might lead to a controversy when regarded as a religious character. However while diffusing the bomb the Batman says, â€Å"If I had the time or the right – I’d say a prayer†. Again, the character of Two-Face is regarded as non religious in traditional sense. Even this has been projected as a villainous character as a result of severe psychosis. The movie reveals how human beings are vulnerable and get more influenced by Satan than by God despite the religious beliefs of some characters. Also the importance of rituals and good deeds or actions can be controversial at times while commenting on a character’s religiosity. Analysis of the ritualistic aspect of the movie The three main characters can be analyzed in the context of rituals and religious beliefs. Harvey Dent or Two-Face who was initially wh ite turns black in the end when he is killed. Batman is represented in shades of gray while the Joker is depicted in black shade. The Joker does not believe in ethics or religion. On the other hand, the Batman, through his actions symbolizes godly deeds but he does not believe in rituals. When the Two-Face is cured from his psychosis state, he is seen to wear the Taoist symbol on his belt. This might give an impression of ritual which according to Nye, is more

How much Macbeths character changes during the course of the play Essay Example for Free

How much Macbeths character changes during the course of the play Essay By reference to three key scenes, shoe how much Macbeths character changes during the course of the play: Act I scene VII, Act III scene IV, Act V scene III The first we hear of Macbeth is when a bloodied soldier looking valiant after battle with great gaping wounds, describes a Great War hero: For brave Macbeth well he deserves that name. Shakespeare uses this speech to show Macbeths loyalty by saying he fought off a whole army and all for king and country. He also said their enemy ran away, then launched another attack and that Macbeth and Banquo fought it off even with their severe wounds: They meant to bath in reeking wounds And they still repelled the second attack, as though with renewed strength: So they doubly redoubled strokes upon the foe. We can see from this that Macbeth is a noble, loyal and trusted man, let alone a war hero. After Macbeth meets the witches, his personality begins to change. He becomes consumed with ambitions. In my understanding it was always there, like a petrol station with petrol running everywhere and leaky gas mains (always a fire hazard), the witches just threw in a Zippo. They had given him two predictions: 1) They greeted him as thane of Cawdor Hail thane of Cawdor (which he wasnt) 2) Then as king hail Macbeth, that shalt be king hear after. After meeting the witches, the Kings messenger came to him and named him thane of Cawdor. He is very surprised at this and writes a letter home to his wife telling her about the things the witches had said, how out of the blue he had become thane of Cawdor and even mentioned about becoming king. This is where Shakespeare introduses Macbeths more sinister side: Why do I yield to that suggestion whose horrid image doth unfix my hair and make my seated heart knock upon my ribs As we can see Macbeth is starting to think of murder. We get another insight into his character from Lady Macbeth. She says that she thinks that he will be too kind to actually commit murder, and that she will have to do most of it then persuade him: Yet I do fear thy nature it is too full o th milk of human kindness We can see from this quote that Macbeth has a conscience and that his wife believes that he would grieve afterwards. When Duncan arrives at Macbeths castle, a banquet is held. We can se in Macbeths opening soliloquy (a dramatic technique show the audience what he is thinking) that he doesnt want to carry on with the murder as he says Could trammel up consequences By Shakespeares use of the word trammel we can se he is thinking of death and if he could just be done with it and that was it, it would be fine but he knows there will be consequences for killing the king: Hear upon this bank and shoal of time, Wed jump thr life to come This shows that the Elizabethans believed in the after life. He also refers to the Elizabethan belief of the king being chosen by god: His virtues will plead like angels trumpet-tongued against the deep damnation of his taking off Later on in the scene we see that Macbeth doesnt want to go through with the murder and wants to call it off: We will proceed no further in this business And he gives three reasons he is his host as his host He is his kin I am his kinsman and his subject Duncan has been extremely kind to him Duncan hath borne his faculties so meek So to make Macbeth commit the murder Lady Macbeth taunts him and calls him a coward: When you durst do it then you were a man And at this Macbeth wants to do it to prove he is not a coward and we can see this from his next line: If we should fail showing he is thinking about the murder. Although Macbeth can wash Duncans blood from his hands he cannot wash it from his conscience: Will all great Neptunes oceans wash this blood clear from my hand? No Macbeth is duly crowned king Banquo reveals his suspicions about Macbeth in a soliloquy: Thou hast it now king, Cawdor, Glamis, all the wired women promised and I fear thou playdst most foully fort Macbeth holds a banquet and invites every one. After this Macbeth hires an assassin to kill Banquo and Fleance his son. Macbeth seems to be losing his moral standing the further he gets into the play. Banquo sacrifices his life to save his son and Fleance gets away. The assassin shows up at the banquet and stands at the door to give Macbeth the news there is blood upon thy face The murderer then seeks praise for the murder of Banquo: Macbeth then asks about Fleance and is agitated to hear that he is still alive: The worm thats fled hath nature in time will venom breed, no teeth for the time present Shakespeare uses a metaphor to show how Macbeth is afraid of Banquo and Fleance Macbeth then goes to sit down at the table but he thinks his place is taken and when the figure stands up it is the ghost of Banquo. No one else can see the ghost. It is only by Macbeths speeches that we can tell he can see a ghost. Macbeth is very scared and starts shouting but Lady Macbeth calms everything down. In a stage whisper, She calls him a coward and says that it is just like the dagger he saw pointing to Duncans room the ghost vanishes and he calms down and they send every one home saying he will be fine in the morning. Shakespeare usage of a ghost reflects king James fascination with the supernatural and the Elizabethans general belief in spirits and ghosts. He also uses stage whispers sililoquy and the idea of no one seeing the ghost except Macbeth, which could just be him hallucinating. So we are not entirely sure whether there really is a ghost there or the pressure of all the killing has got to him and he has flipped and had hallucinations. After this he is still paranoid and so to stop this he goes to see the witches again and this time the show him three visions. 1) Beware Macduff 2) None of woman bore shall harm Macbeth 3) Macbeth shall never vanquished be Until great Birnam wood comes to Dunsunane hill He is woken up by Lenox and decides to kill Macduff to be safe but he has fled to England to help Malcolm at this Macbeth is so angry he orders the assassins to kill his wife and kids and this shows a complete depletion of his morals. He as ordered assassins to go kill innocent children and women without a second thought. There has been a character reversal and now Macbeth has no morals and lady Macbeth as been driven mad with guilt. At the start, Macbeth would not kill Duncan and Lady Macbeth drove him to it. In the next scene Macbeth is getting hundreds of reports of the English force amassing on the horizon, but of-coarse he had the predications from the witches and feels confident. He doesnt worry about them Bring me no more reports, let them fly all. Till Birnam wood remove to Dunsinane This shows an air of self-confidence and pride. He even accuses Thanes that ran away of being false which was very ironic as he killed the king then fly false thanes. From his opening speech we can see he thinks he is invincible: The mind I sway by and the heart I bear shall never sag with doubt nor shake with fear. When his servant comes he is white and pale so Macbeth calls him lily liveried, because the Elizabethans believed that courage came from the liver. When the doctor said that there was no cure for lady Macbeth that she had to cure herself Macbeth insulted him, which is a valid point, as King James 1st didnt believe in doctors. Macduff and Malcolms army burst into the castle and the first wave come to find Macbeth and die until Macduff finds him and they fight. Macduff tells Macbeth he was born by caesarean section and so was not born of woman and he kills Macbeth. In conclusion I would say that Macbeths character changes drastically throughout the play. At the start he is a good and noble soldier who would never betray the king but gets persuaded easily by his wife. Then as the story progresses we see him start to lose morals as he orders the killing of Banquo on his own but is still upset about it, we can see that because of his hallucinations (seeing the ghost). Then he orders the killing of lady Macduff and her children showing he has gone of the scale and is totally evil. Whilst fighting Macduff he is arrogant and spares his life at one point in the fight. So when Macbeth is told that Macduff is not born of women he is shocked and dies a wicked fool. So we see the down fall of such a brave character we saw at the start because of a few predictions and the ambition. For if he saw what being king would do to him I doubt he would have wanted to be king and would have been contented but was tricked by the evil of the witches.

The History Of The Kitchen Refrigerators

The History Of The Kitchen Refrigerators Today, refrigerators have become an essential part of every kitchen (Tatum, 2010). Refrigeration is used to store meat, vegetables among other foodstuffs at low temperatures, thus inhibiting spoilage due to microbial activity. The process of essentially, manufacturing or making a refrigerator was gradual and begain in the 18th century. It culminitated with Carl von Lindens work in 1876. (Bellis, 2010 Tatum, 2010) Evidence suggests that since 500 AD, man has known to produce ice by natural processes. Egyptians and Indians made ice on cold nights by setting water on earthenware pots. Later on in the 1700s, England servants in the 1700s collected ice in the winter and put into icehouses, which then provided cool storage in the summer. (Bellis, 2010 Tatum, 2010) In 1748, William Cullen of the University of Glasgow developed an entirely new process that consequently lead to an artificial cooling medium being developed. (Tatum, 2010). His experiment produced ice. However; he was unable to explain what it meant. Around 1805, the Oliver Evans was involved in designing a refrigeration apparatus, but unfortunately, he didnt build one until Robert Perkins improved on his creation in 1834. (Bellis, 2010). Thomas Moore coined the word refrigerator for these machines. However, as today Perkins and Evans machines are called iceboxes. In 1844, Dr. John Gorrie, a physician, was able to construct a working unit that was based on both Evans and Perkins model. constructed. It was because of a outbreak of yellow fever that led to Gorrie creating the unit, which was used to cooling the air. (Bellis, 2010 Tatum, 2010) Gorrie is credited as being the one who invented the refrigerator by many. (Bellis, 2010) However the situation began to change, when Carl von Linde (1842-1934), a German mechanical engineer published an essay on improved refrigeration techniques, in 1871. He proposed a continuous process of liquefying gases in large quantities. In 1873, he invented the first practical and portable compressor refrigeration machine. (Tatum, 2010) He obtained a patent for his refrigerator in 1877 from the German Imperial Patent Office. He made use of gases namely ammonia, sulphur dioxide and methyl chloride. (Bellis, 2010 Tatum, 2010) In the 1900s, various refrigeration models were seen. Noteworthy refrigerator models included Servel, Frigidaire, Electroflux among others. (Bellis, 2010) These models of the 1900s had several advancements since designs of pioneers such as Gorrie. By 1918, automatic controls were part of some models already. (Tatum, 2010) The gases used namely ammonia, sulphur and methyl chloride were replaced by Freon in the 1920s in order to comply with safety standards. When one looks at the history, it shows that in 1918, automatic parts were already installed. This included automatic dials that aid in the operation. It was rather unfortunate that the units were not self contained as different parts were separately placed from each other. It wasnt until 1923 that self contained refrigerators began appearing. (Bellis, 2010) Ice cube trays were also introduced. (Tatum, 2010) Although many advancements were made, the modern refrigerator was put in mass production until 1946 i.e., after the World War II. (Bellis, 2010 Tatum, 2010) People, in the the 1950s and 1960s were the ones that witnessed a variety of technological innovations by engineers and scientists of the day. Among them were: (i) automated defrosting and (ii) making of ice. Today, there are many features that are intertwined with the features of the olden days and includes power failure alerts, ice cabinets among others. (Bellis, 2010 Tatum, 2010) To present, domestic refrigerators are present in almost every home worldwide. Due to the models created by Gorrie, Cullen, Carl von Linche among others, the refrigerator has thus become one of the machines or applicances that is integral to us every day. (Bellis, 2010 Tatum, 2010) TYPES OF REFRIGERATORS Refrigerators are classified into three types: (Suyambazhahn, 2009) Air refrigerator Vapour compression refrigerator Vapour absorption refrigerator VAPOUR COMPRESSION REFRIGERATION SYSTEM The vapour compression refrigeration system is most commonly used in refrigerators. A refrigerant is a gas with characteristics that make is suitable for refrigeration and air conditioning. R-22 is a commonly used refrigerant. This cycle works in four phases, which are described later on because it is similar to the refrigeration cycle. Figure 1 Vapour compression refrigerator (Suyambazhahn, 2009) This type has various uses such as: (Suyambazhahn, 2009) Air conditioned cinema theaters, restaurants, hospitals, residential buildings for comfort. Advanced medicines which are manufactured and preserved only in special atmospheric conditions. Preservation of food products. VAPOUR ABSORPTION REFRIGERATION SYSTEM The principle of vapour absorption was first discovered by well known scientist Michael Faraday in 1825. But this concept is applied to refrigeration during 1860s by French Scientist Ferdinand Carve. The commonly used refrigerant for vapour absorption system is ammonia, NH3. In order to change the conditions and phase of refrigerants, heat energy is utilized in vapour absorption system where as mechanical energy is utilized in vapour compression systems. In a vapour absorption system, compressor is replaced by an absorber, a pump and a generator. The vapour at the low pressure that leaves the evaporator is then moved to the absorber. The absorber contains weak ammonia solution. The vapour leaving from the evaporator is dissolved in the weak ammonia solution to form a strong solution. Cooling water is used to cool he absorber. The strong solution from the absorber is pumped to the generator. The strong solutions pressure is increase by the pump (10 bar) and is circulated through the system by pump. Figure 2 Vapour absorption refrigerator schematic (Rajadurai, 2009) COMMONLY USED REFRIGERANTS Even though there are many types of refrigerants which are used in various applications, the following types are important from the subject point of view. AMMONIA It is the most widely used refrigerant. It is mainly used as the refrigerant in cold storage plants and also in ice making plants. Its boilined point at atmospheric pressure is -33 oC and it has a high latent heat and high critical temperature which are desirable properties of ammonia as a refrigerant. Also it is less expensive. But its usage becomes secondary due to the following characteristics: (Rajadurai, 2003) It is toxic It is flammable It has an irritating odour It attacks metals like copper and brass in the presence of moisture CARBON DIOXIDE The demerits involved in the usage of ammonia can be eliminated by using carbon dioxide. It is non toxic and odourless. It has a boiling point of -77.6 oC at atmospheric pressure. But it is not so often used because of its high operating pressure that is the operating pressure of CO2 is very high as 70 bar. (Rajadurai, 2003) SULPHUR DIOXIDE It has a boiling point of -10 oC at atmospheric pressure. IT has a very low working pressure and a large latent heat with a high critical temperature. It is non flammable and on explosive. Even though there are many positive characters mentioned, the SO2 refrigerant is very toxic and it has an irritating pungent odour. Also it is very corrosive in contact with moisture. (Rajadurai, 2003) FREON 12 (or DICHLOR DI FLUOROMETHANE) It has a boiling point of -30 oC at atmospheric pressure. It is non toxic, non explosive and on flammable. It is odorless and colourless. It is non corrosive to any metal. But it is highly costlier than other types of refrigerators. But the main demerit with respect to this is type is the large amount of refrigerant that is necessary to be circulated for a given output. It is generally abbreviated as R-12 or F-12. (Rajadurai, 2003) FREON 22 (or DICHLOR MONO CHLORO METHANE) It is widely used as the refrigerant for domestic refrigerants. It has all positive points like the characters posed by Freon 12 such as non toxicity. It is colourless, odourless and non corrosive to metal. Additionally, the amount of refrigerant required is only 1.3 kg/min per tonne for refrigeration. (Rajadurai, 2003) PRINCIPLES OF OPERATION THERMODYNAMICAL CONSIDERATION THE SECOND LAW The second law of thermodynamics is described as the most fundamental law of science (Khemani, 2008). It is fundamental in the sense that it can be used to explain not only refrigerators and heat engines but highly advanced phenomena such as the big bang. It has been put aptly in the words of Classius as it is impossible for a process to occur that has the sole effect of removing a quantity of heat from an object at a lower temperature and transferring this quantity of heat to an object at a higher temperature (Mortimer, 2008). This essentially means that heat cannot flow spontaneously from a cooler to a hotter body if nothing else happens (Mortimer, 2008) i.e. there needs to be an external agency to effect the change. In kitchen refrigerators, the closed box inside is able to be kept cool by the removal of heat from the inside of the box and deposits it to the outside. As per the second law, the heat will not move from the cold to the hot freely so it is important for it to be made to do so, this is done by using an intermediate fluid (Littlewood, 2004) which absorbed heat on the inside. This intermediate fluid is known as a refrigerant and carries the heat outside of the box whereby it it released into the air as heat as shown in Figure 3 (Littlewood, 2004). Figure 3 the flow of heat within the refrigerator a schematic (Littlewood, 2004) The fluid circulates within the pipe which passes in and out and can be found at the back of the refrigerator. It is kept by using a compressor (which uses electricity from the home) and allows it to work effectively without violating the second law of motion. (Littlewood, 2004) THE FIRST LAW Refrigerator takes in energy from a region that needs to be cooled and deposits this heat energy into some other region that is outside of the refrigerator. In order to do work, there needs to be some mechanism in place, where the work done by a compressor and its electric motor is utilized. Using the First Law of Thermodynamics we can write: (Littlewood, 2004) Figure 4 the first law of thermodynamics (Littlewood, 2004) QC QH = -W Where: Qc energy or heat of the cold system QH = energy or heat of the hot system W = work done Since work is done on the refrigerator by the compressor, the work is done is deemed negative because of sign conventions. This is part of the first law (Littlewood, 2004). The refrigerator is termed as a closed system and it possesses a constant composition: U = U + (à ¢Ã‹â€ Ã¢â‚¬Å¡U/à ¢Ã‹â€ Ã¢â‚¬Å¡V) T dV U = U + (à ¢Ã‹â€ Ã¢â‚¬Å¡U/à ¢Ã‹â€ Ã¢â‚¬Å¡T) V dT U = U + (à ¢Ã‹â€ Ã¢â‚¬Å¡U/à ¢Ã‹â€ Ã¢â‚¬Å¡V) T dV + (à ¢Ã‹â€ Ã¢â‚¬Å¡U/à ¢Ã‹â€ Ã¢â‚¬Å¡T) T dT dU = (à ¢Ã‹â€ Ã¢â‚¬Å¡U/à ¢Ã‹â€ Ã¢â‚¬Å¡V) T dV + (à ¢Ã‹â€ Ã¢â‚¬Å¡U/à ¢Ã‹â€ Ã¢â‚¬Å¡T) V dT According to Bain (2010), there are four basic parts to any refrigerator: Compressor Heat Expansion valve Refrigerant The exchanging pipes are a coiled set of pipes that is placed strategically outside of the unit. The refrigerant as will be discussed later on is a liquid that has the ability to evaporate efficiently so that inside the refrigerator is kept cooled. (Bain, 2010) A gas can be cooled by adiabatic expansion if the process is enthalphic. The gas expands through a process barrier from one constant pressure to the next and the temperature difference in observed. Insulation of the system made the process adiabatic. The result is that a lower temperature was absorbed on the on a low pressure side and the change in the temperature is proportional to the change in pressure. (Bain, 2010)  Ã¢â‚¬Å¾T  µ  Ã¢â‚¬Å¾P Figure 5 schematic of a domestic refrigerator (Bain, 2010) Figure 6 heat transfer within a refrigerator (Popular Mechanics, 1993) When an energy |qc| is removed from a cool source at some temperature Tc, and then deposited in a warmer sink at a temperature Th, the change in entropy is: (Atkins dePaula, 2006) Atkins dePaula (2006) also indicated that the process is not spontaneous because the entropy generated in the warm sink is not enough to overcome the loss of entropy from the cold souce. And because of this more energy needs to be added to the stream that enters the warm sink to generated the entropy required by the system. They further indicated that the outcome is expressed as the coefficient of performance, c: The less the work required to achieve a given transfer, the greater the coefficient of performance and the more efficient the refrigerator (Atkins dePaula, 2004). Because |qc| is removed from the cold source, the work |w| is added to the energy stream, the energy deposited as the heat in the hot sink |qh| = |qc| + |w|. Therefore, From: We can have an expression in terms of the temperature alone, which is possible if the transfer is performed reversibly (Atkins dePaula, 2006): Where: c = thermodynamic optimum coefficient of temperature Tc = temperature of the cold sink Th = temperature of the hot sink For a refrigerator, it important that a very low coefficient of performance. For a refrigerator withdrawing heat from ice cold water (Tc = 273 K) in a typical environment (Th = 293K), c = 14. As an example, to remove 10 kJ (enough to freeze 30 g of water), requires transfer of atleast 0.71 kJ as work. (Atkins dePaula, 2006) The work to maintain a low temperature is very important when designing refrigerators. No thermal insulation is perfect, so there is always some form of energy flowing as heat into a specific sample at a rate that is proportional to the temperature difference. (Atkins and de Paula, 2006). Figure 7 (a) the flow of energy as heat from a cold sink to a hot sink is not spontaneous as described the first law. Notice that the entropy increases but it is larger for the hot sink as compared to the cold sink. (Atkins dePaula, 2006). This contributes to a decrease in the NET entropy. (b) The process becomes feasible if work is provided to add to the energy stream. Then the increase in entropy of the hot sink can be made to cancel the entropy of the hot source (Atkins dePaula, 2006) The rate at which energy leaks happen is written as: Where: A = a constant that depends on the size of the sample and details of the simulation Tc = temperature of the cold sink Th = temperature of the hot sink The minimum power, P, required to maintain the original temperature difference by pumping out that energy by heating the surroundings is: As can be seen the power increases as the square of the temperature difference (Th Tc). THE REFRIGERATION CYCLE The gas is pumped continuously at a steady pressure, the heat exchanger (which brings the required temperature) and then through a porous plug inside container that is thermally insulated. A phase change heat pump uses a liquid, as described earlier, that has a very low boiling point, which is used to move heat from an area where it is cooler to one where it is warmer. The refrigerant requires energy so that it can evaporate, which essentially allows it remove the heat from the surroundings by absorbing it. When the vapor condenses, the energy absorbed in the process is released which is also in the form of heat as might be expected. A refrigerant is a compound used in a heat cycle that undergoes a phase change from a gas to a liquid and back. Latent heat describes the amount of energy in the form of heat that is required for a material to undergo a change of phase (also known as change of state). Two latent heats are typically described. (Bambooweb, 2009)For other uses, see CFC (d isambiguation). The pump operates a cycle in which the refrigerant changes state from its liquid form to the vapour form and vice versa. This process occurs repeatedly and I known as the refrigeration cycle. In this cycle, the refrigerant condenses and heat is released in one point of the cycle. It is the boiled (or evaporated) so that it absorbs heat in another point of the cycle. The widely used refrigerant is hydro fluorocarbon (HFC) known as R-134a and CCl2F2 (dichlorodifluoromethane). Other substances such as liquid ammonia, propane or butane, are be used but because of their highly flammable nature, they are disregarded as a good refrigerant. 1930 (MCMXXX) was a common year starting on Wednesday (link is to a full 1930 calendar). (Bambooweb, 2009)For other uses, see CFC (disambiguation). In the refrigerator the fluid used (e.g. CCl2F2 ) fluid is liquefied by compression then vaporized by sudden expansion which gives a cooling effect. The compressor, in itself does not create a cooling effect directly, as might be expected. The cooling effect is fashioned when the refrigerant absorbs the heat so that it is removed and the area becomes cooler. This is accomplished with a heat exchanger. (Bambooweb, 2009)For other uses, see CFC (disambiguation). A heat exchanger is a device built for efficient heat transfer from one fluid to another, whether the fluids are separated by a solid wall so that they never mix, or the fluids are directly contacted. The refrigeration cycle can be divided in two parts: The liquefaction stage The evaporation stage LIQUEFACTION STAGE The refrigerant vapour undergoes recycling by itself into the liquid form by the extraction of heat from a vapour at a higher temperature. The refrigerant is compressed by the compressor where a low pressure and low temperature condition is created. This is accomplished by an evaporating coil. During the compression process, the vapour of the refrigerant undergoes a temperature change (as an effect of the compression process). Additionally, the work of compression to create the high temperature and pressure vapour also contributes to the temperature change experienced by the vapour. The condenser that is located where the temperature is higher (i.e. the higher temperature heat sink) collects the vapour. Heat is then removed from the refrigerant and in lieu of this it condenses to its liquid state, hence the name for the condenser. (Mortimer, 2003 ; Brain, 1994 ; Bellis, 2010) Using the Joule-Thompson coefficient: For a perfect gas  µ = 0 Cp + Cv = (à ¢Ã‹â€ Ã¢â‚¬Å¡H/à ¢Ã‹â€ Ã¢â‚¬Å¡T)p (à ¢Ã‹â€ Ã¢â‚¬Å¡U/à ¢Ã‹â€ Ã¢â‚¬Å¡T)p Introducing: H = U + pV = nRT into the first term: Cp Cv = (à ¢Ã‹â€ Ã¢â‚¬Å¡U/à ¢Ã‹â€ Ã¢â‚¬Å¡T)p + nR (à ¢Ã‹â€ Ã¢â‚¬Å¡U/à ¢Ã‹â€ Ã¢â‚¬Å¡T)p = nR EVAPORATION STAGE As the refrigerant leaves the condenser, the next part of the cycle begins. This is accomplished when a high temperature and high pressure liquid passes through a metering device that is found within the refrigeration. The valve allows a specific quantity of liquid coolant to pass into the evaporation chamber. Evaporation chambers are relatively low pressure and this encourages coolant evaporation. Newly evaporated coolant is drawn though the cooling coils (typically a fan is used to blow air over the coils). Thus, the evaporative process produces the cooling effect. The refrigerant then is pulled to the compressor in the suction line where it will be compressed into a high temperature, high pressure gas and sent to the external heat sinking coils. Capillary action or capillarity is the ability of a narrow tube to draw a liquid upwards against the force of gravity. (Mortimer, 2003 ; Brain, 1994 ; Bellis, 2010) A refrigerator pumps heat up a temperature gradient. The cooling efficiency of this operation depends on the amount of heat extracted from the cold temperature reservoir (the freezer compartment), , and the work needed to do so. Since a practical refrigerator operates in a cycle to provide a continuous removal of heat, for the cycle. Then, by the conservation of energy (or first law), , where is the heat ejected to the high temperature reservoir or the outside. (Mortimer, 2003 ; Brain, 1994 ; Bellis, 2010) The measure of a refrigerator performance is defined as the efficiency expressed in terms of the coefficient of performance (). Since the purpose is to extract the most heat () per unit work input (), the coefficient of performance for a refrigerator, , is expressed as their ratio: (Mortimer, 2003 ; Brain, 1994 ; Bellis, 2010) Where, the conservation relationship given above is used to express the work in terms of heat. For normal refrigerator operation, the work input is less than the heat removed, so the is greater than 1. Refrigerators are commonly referred to as heat pumps of more specifically a it is a reversible heat pump because they basically pump heat. (Mortimer, 2003 ; Brain, 1994 ; Bellis, 2010) Figure 8 A diagram of the vapor compression refrigeration cycle that is used in heat pumps. The cycle shows the following: (i) condenser, (ii) expansion valve, (iii) evaporator, (iv) compressor. (Karin, 2003) It is commonly believed that by opening a refrigerator, itll cool the kitchen. However this is entirely opposite, opening a refrigerator or freezer heats up the kitchen because the refrigeration cycle does not accept the air from the outside (Karlin 2003). The heat is referred to as the heat dissipated from the compressors work and also includes that heat that s removed from within the refrigerator as well. (Karlin, 2003) The COP (in a heating or cooling application), provided that it undergoes steady state operation, is given by the following equation: Where: ΆQcool is the heat extracted from a cold reservoir, ΆQhot is the heat delivered to a hot reservoir. ΆA is the dissipated work by the compressor. THE CARNOT ENGINE The Carnot refrigerator is the maximum limit to the COP (efficiency) of a refrigerator system. Although we cannot make the carnot refrigerator, it tells us the maxium or best performance that can be garnered from a real refrigerator. The carnot refrigerator is sort of ideal in its design. As described earlier by Atkins dePaula (2006) with the Carnot engine, the COPc of a Carnot refrigerator depends (i) the temperature of the region that needs to be kept cool which has a characteristic temperature, TC and the temperature of the region where the heat needs to be transferred to, having a characteristic temperature, TH. It is equal to: (Littlewood, 2004) EFFICIENCY The efficiency of a refrigerator is described by a special coefficient known as a coefficient of performance and is defined in terms of the following parameters: SUMMARY OF THERMODYNAMICS OF A REFRIGERATOR AFTER ONE CYCLE Change in internal energy = 0 Change in heat is > 0 Total work > 0 Total volume change = 0 Change in Gibbs free energy = 0 Entropy change of the system = 0 Entropy change of the universe > 0
