Education Important Factor In A Developing Country

Education Important Factor In A Developing Country For thousands of years, education has been an integral part of society. But is it the single most important factor in the development of a developing country? I believe education is of great significance instead of the most important factor. First and foremost, a complete education system provides large number of qualified people with advanced knowledges and skills in a wide range of subjects. Through attending various educational facilities, including but not limited high school, college and university, people can get themselves prepared for and contributed to the development of the country, which clearly requires the effort from all profession. For instance, if you want to be an architect, you go to university to learn basic knowledge in construction and designing, if you want to be doctor or nurse, you go to a medicine school to get familiar with all kinds of medicines and acquire some first-hand experience. In addition to talents cultivation, education in itself has tremendous influence on spirit civilization, which accounts for a large part in a countrys development. As a place where knowledge handed down and wisdom passed around, school represent the homeland of scholars like Socrates and Confucius, who had huge impact on the promotion of spirit civilization, and the birthplace of innovative ideas like democracy. Whats more, the improving of education involves many constructions of schools and universities which have positive effect on local economy. For instance, the university i attended, expand a new campus in the countryside area in Nanjing. With more and more students came to spend their four or even more years in here, the local economy was tremendously accelerated, restaurants, cafes, hotels, bookstores and supermarkets mushroomed in few years.

Relax and forget about the outcome of the test. Take your time to jot down two or three good ideas before you start writing, and then write only about them and nothing else. Include them all in your conclusion. In developing country, the most important thing is the way how to develop in firm foundations. And one of the firm foundations is education. This essay will discuss why education is the single most important factor in the development of a developing country. Firstly, in the life, people can live without education but education is the fast way helping people improve knowledges and experiences.Basic education provides people with a greater understanding of basic daily informations about life as well as of their own potential. A country with a strong education system can more definitely develop in the future.In developing country, improving citizens learning is very important because their attitude towards a question can influence on development of country.It is necessary to invest in education is because children will be laborer in future. If they work without education, this could be wasting a lot of resources and lead their country to go down. Secondly, in all countries especially developing countries, the way to develop is do own self. Developing education means the own way to develop country.Theres a famous saying If you give a man a fish you feed him for a day, if you teach the man to fish you feed him for a lifetime.In some countries, the government invests a big part of the profits in weapons but its really waste time and money. The long investment is in education.With a good education system, people can study easily, they can overtake the newest technology then they apply in their life. To sum up,education factor in developing country is very important.Developing education is the most needful.Its a firm foundation for most countries especially developing country. I posted it in dethi.com and now, I post it again in here.I hope people can help me.Thanks Today, having a good education is really important for people. So that, most people apply a lot of tecniques which help them their work and school. Education is the single most important factor in the development of a country. Countries need a lot of things for their future because educated people are good at many things, such as communication and also to know how to improve themselves. First of all ,being good at communicating which has some advantages for people is very urgent for todays life .It brings people a lot of feasibility and success. For example, at work people get on well and behave eachother suitable. They find possibility and become successful .But if they dont do these ,they can lose many things .In addition to this, they may be hopeless and destroy their future. For these reason, people can have a good communication thanks to only education .To sum up, having good education opens people new door in their work and give them many things for their life. Another issue in the development country is that people know how to advance themselves during their all lives. For instance, educated people improve themselves during their all lives. They learn many things and in the future when they face with some problems ,they know how to deal easily, because they read or saw previous anywhere these problems .As a result, improving themselves about a lot of things is very significant for people. In the light of the above-mentioned reasons ,a country cannot develop without the education which requires an essential communication and improving themselves .In my opinion ,the education includes the most things that advance to the country.

Differences In Animal Phyla Essay -- essays research papers

Because they are grouped in the same kingdom, the nine animal phyla share the same fundamental characteristics- they are multicellular, heterotrophic eukaryotes that obtain nutrients through ingestion, they lack cell walls, they have nervous tissue and muscle tissue, and they reproduce sexually and have a unique embryonic life cycle. However, the animal phyla have a great number of differences as well. Some are visible to the naked eye, while others are less obvious, and still more cannot even be seen after embryonic development. What are these differences, and how did they shape the development of the phylogenetic tree? In animals, the embryo becomes layered through the process of gastrulation, or the formation of the two layered, cup-shaped embryonic stage from a blastula. These layers are called germ layers. Most animals are triploblastic, meaning they have three germs layers. These are the ectoderm, the endoderm, and the mesoderm. The ectoderm is the outermost layers which forms the body’s covering and the central nervous system. The endoderm is the innermost germ layer. It forms the digestive tube and gives rise to most organs. The third layer, the mesoderm, exists between the endoderm and ectoderm. It forms the muscles and most other organs towards the upper layer of the animal. Diploblastic animals, or animals with only two germ layers, lack mesoderm. There are only two diploblastic phyla: Porifera, the sponges, and Cnidaria, the â€Å"bag animals.† All other animals are ...

Freud’s theory of Psychosexual Development Essay

I will begin my essay by outlining Freud’s theory of Psychosexual Development and I will then go on to evaluate how far this help us to understand a client’s presenting issue. Freud’s theory of psychosexual development begins with the belief that human beings are purely driven by biology, in the form of the libido or sexual energy. The driving force of the libido is divided into five stages, he argues, and our early experiences during childhood are responsible for the development of a healthy personality, or if any individual were to experience trauma during these stages then it would result in disruption in the child’s personal development and the child may become stuck in this stage, resulting in neurosis. This five stages of sexual libido are: The Oral Stage – from birth to about 18 months – is where the child directs all its attention to the mouth in the form of sucking, eating and drinking. If stuck in this stage the client may still like to use their mouth a lot, resulting in the client presenting with overeating, drinking, smoking or talking The Anal Stage – from about 18 months to three years – is where the child directs their attention to the elimination of waste, and of the feelings experienced by the expelling of waste. This is also the stage where the child first experiences an element of control over themselves, as to where they excrete or and indeed whether or not they excrete their waste product. The child learns that he can use his bodily functions to elicit attention from his carer by excreting on the floor rather than in the potty. Clients stuck in the anal stage may be either anally retentive or expulsive in personality. Those that are anally retentive individuals are controlling and like to have everything in order – they may suffer from OCD and have quick outbursts of anger. Anally expulsive individuals tend to be untidy and disorganised. The Phallic Stage – from about three to five years – is where children become aware of their genital regions. This is the stage where the child starts to become aware of the differences between male and female genitalia, and their energy is spent undressing themselves, and perhaps others, in order to explore these differences. It is also the stage  of manipulating the genitals and the discovery of pleasure in doing so. It is during this stage that the Oedipus conflict arises; the belief that a boy has incestuous cravings for his mother and views his father as a rival for this affection. The boy also fears his father, as his father is bigger than him in all ways including his penis. Freud argued that the boy feels castration anxiety at this stage as a result of repressed sexual desire for his mother. If the boy has the correct parenting at this stage, then the boy identifies with the father and comes to have harmless affection for the mother. The Electra complex is the female counterpart. It is based on the view that each girl wants to possess her father and replace her mother. A phallic fixation can lead to an individual with a narcissistic, homosexual, egotistical or overly sexualised personality that may lead to serial marriage, polygamy or polyandry. The phallic fixation tends to use sex to discharge emotional tension and will often have sexual relationships that are superficial and lacking in love and affection The Latency Stage – from five years to adolescence. In this stage, sexual motivated needs subside as the child focuses their attention on developing other skills needed for their survival. A child stuck in this stage may have issues forming sexual relationships and have trouble expressing themselves sexually, leaving themselves and or their partners sexually unfulfilled. The Genital Stage – from adolescence to adulthood. During the onset of adolescence, the child moves from self-love or narcissistic love to diverting this love to others. It is argued by psychotherapists that are advocates of this theory that individuals disrupted during the ‘Genital stage’ may result in sexual disorders such as fetishes and paedophilia. According to Freud, only symptoms can be modified, and not the behaviour of the client – this can be done in two ways: 1. Lessening of the intensity of the unconscious urges, by bringing them to the consciousness or by strengthening the defences against them. An example of lessening the client’s behaviour is by encouraging a client to leave a job where aggressive urges were continually being aroused by an oppressive boss. 2. Alternatively the client can act out their urges in a more acceptable and symbolic way. An example being that anal urges can be expressed through pottery, as an alternative to faecal play. Feminists would argue that Freud’s theory concentrates on male sexual development, and provides little in understanding female sexuality. Freud’s work has also  been criticised for over emphasising sex drive and little else in order to assess a client’s presenting issue. Carl Jung and Fromm, two students of Freud, agreed with this statement, but used Freud’s work to develop their own theories, which I outline below. Carl Jung (1875 -1961) believed that that the libido was not just sexual energy, but instead generalised psychic energy. The purpose of this psychic energy was to motivate the individ ual in a number of ways, including spiritually, intellectually, and creatively. It was an individual’s source for seeking pleasure as well as reducing conflict. Jung placed greater emphasis on the unconscious than Freud; he argued that the psyche was composed of three components. Firstly, he believed that the ego is conscious, because people are aware of their own thoughts, memories and emotions. The unconscious mind, Jung believed, was split into two parts (the remaining two components): The personal unconscious, which is the same as Freud’s belief, in that it consists of repressed memories. Jung explained an important feature of the personal unconscious called ‘complexes’. A complex is a collection of thoughts, feelings, attitudes and memories, which focus on a single concept. The more elements attached to the ‘complex’ the greater its influence on the individual. The second deeper level is the Collective consciousness. This level of unconscious is shared with other members of the human species, comprising of latent memories from our ancestral and evolutionary past (‘The form of the world into which a person is born is already inborn in him, as a virtual image’ Jung, 1953). Jung called the ancestral memories and images ‘archetypes’. For Jung, our primitive past becomes the basis of the human psyche, directing and influencing present behaviour. Important archetypes include: the persona, or our social mask, just like an actor in a play; Anima/Animus, or our male and female sides – this comes from living side by side with the opposite sex for centuries; the shadow, similar to Freud’s ID, comprised of our animal urges or survival and reproduction. Jung argued that the psychological development of both sexes was undermined as the development of western society has led to the devaluation of feminine qualities over the predominance of the persona, leading to insecurity. Jung agreed with Freud that a person’s past and childhood experiences determined future behaviour, but he also believed that we are shaped by our future aspirations too. Erich Fromm (1900 – 1980) differed with the Freudian  emphasis on unconscious drives. Fromm argues that a person’s drives were not purely biological – he believed that man had free choice to decide on whatever action he felt appropriate and therefore gui ded their own destiny. Fromm saw conflict arising within the individual, when they had to weigh up the freedom of choice with the fear of uncertainty, when making these decisions. As a sociologist and psychologist, his theories integrated both psychology and Marxist Historical Materialism. Fromm argued that each socioeconomic class fosters a particular character, governed by ideas and concepts that justify and maintain the socioeconomic system. Fromm believed that the unique character of human existence gives rises to eight basic needs. Firstly Unity, as human beings have lost their original oneness with nature, they need to relate in order to overcome their isolation. Secondly their relatedness with others, care, respect and knowledge. Thirdly humans need to transcend their own nature, as well as their passivity and randomness of existence, which can be accomplished either positively, by loving and creating, or negatively, through hatred and destruction. Fourthly the individual also requires a sense of rootedness or belonging, in order to gain a feeling of security, and sense of identity. Fifthly the sense of identity which is expressed non-productively as conformity to a group and productively as an individual. Sixthly is need is for orientation understanding the wor ld and our place in it. Seventhly is excitation and stimulation or actively striving for a goal rather than simply responding. Eighthly is effectiveness the need to feel accomplished. This Orientation can be achieved either through assimilation (relating to things) or socialisation (relating to people). Fromm identified several character Orientations in Western Society. Authoritarianism – when an individual cannot come to terms with this freedom, he could avoid his responsibilities by withdrawing beneath the protection of someone or something else. Examples of this include God, a specific political leader of party, an institution of even one’s carer. Receptive Orientation – this is common in a society which encourages exploitation of the individual, who then seeks solace in affection and related comforts, such as eating, where the individual can only take and not give. Exploitative Orientation – the defence being the aggressive possession of goods, usually those of others. Examples being the plundering of goods in historical times, or in more modern times, those  nations that seek the territories and chattels of others. Productive Orientation – which donates love and tolerance towards others, and an acceptance of their freedom, with the ability to use this orientation to their advantage, without harming others. Hoarding Orientation – the ‘I want – I need’ society, based on material wealth. If one owns objects, then the individual can be seen, at least in his eyes, as clever and powerful. These individuals are threatened by the outside world and cannot share. Marketing Orientation – this is people copying or being influenced by the media and advertising by wearing the latest fashions. Individual personal qualities are redundant over what looks good. The individual sees themselves as a commodity to be bought and sold. Fromm added two further states: Necrophilous character- attracted to death Biophilous character – drawn to life. According to Fromm, gaining independence from one’s parents leads to a profound sense of loneliness and isolation, which the individual attempts to escape by establishing some type of bond with society through social conformity and submission to authority. By relating both Jung and Fromm’s work to our clients, they have made us aware of the client’s wider world or heritage into which he or she is born. Jung would argue that a Muslim woman may have low self-esteem and isolate herself from others, but these presenting issues are more down to the client’s collective consciousness than their childhood. In this case, Jung helps us as therapist to understand that the client’s neurosis may not arise from bad parenting, but from something primal based upon evolution within the individual. Fromm’s Socio- economic theories also provide us with insight of the client’s wider world, and how neurosis can arise due to external economic forces that dr ive the client’s neurosis in an exploitative and materialistic society that values things over the human existence. Both would argue that it is our environment rather than biology that constrains us, in the form of society and culture. For Jung and Fromm, in order to understand the client’s presenting issue, we must also understand their culture and the way in which they relate to the economic society into which they are born. An alternative view to Freud’s psychosexual development is that of the Behaviourist approach. Behaviourists believe that what is learned can be unlearned. Skinner built upon the work  of Pavlov’s classical conditioning experiments (1927) and his use of dogs as subjects, and the Little Albert experiments of Watson and Rayner (1920). To further these experiments, Skinner (1938) designed a Puzzle box and, by using rats, he showed that by using both positive and negative reinforcements, he could change the behaviour of the rats, as their behaviour is affected by consequences. He called this Operant Conditioning to which he identified three responses: Neutral Operants: responses from the environment that neither increase nor decrease the probability of a behaviour repeated. Reinforces: responses from the environment that increase the probability of a behaviour being repeated – this can be ether positive or negative Punishers: Responses from the environment that decrease the probability of a behaviour being repeated. Punishment weakens behaviour. Skinner concluded that there was a Law of Effect, and that by using reinforcement, behaviour tends to be repeated, while behaviour which is not reinforced tends to die out. As human beings, we often respond to verbal Operants by taking advice, listening to the warnings of others and by obeying given rules and laws. This helps us understand the development of children, as the feelings associated with behaviour are controlled by conditioning. If the child has been positively rewarded, then the child is more likely to repeat those behaviours happily and willingly, feeling that they are doing what they want to be doing. If on the other hand the child avoids these behaviours due to negative reinforcement, they will be inclined to feel that their freedoms are being repressed, resulting in feelings of negativity, which could led to depression or anxiety. The work of Skinner, Pavlov, Watson and Rayner has led to the development of different treatments, such as C ognitive behavioural therapy and talking therapy that will help you manage your problems by changing the way you think and behave, commonly used to treat anxiety, depression and phobias but can be useful for other mental and physical health problems. In conclusion, Freud’s work on psychosexual development does help us in part to understand a client’s presenting issue, by understanding that their behaviour may very well stem from how their parents handled the child’s psychosexual development. By accepting this assertion, it also helps us to understand that what we, as society, view as very disturbing or deviant behaviour can arise from childhood trauma. This allows the therapist, and society, to be more  compassionate to such clients. An example of this is that Freud stated that homosexuality is neither a sinful nor a criminal act, but rather a condition that arose from childhood biological and psychological factors, and was just a ‘variation of the sexual function’, and because of this is could not be treated by punishment or therapy, but should just be accepted. Freud’s work, as already discussed, is limited in understanding the client’s total world, however we must understand th at Freud’s work was the first of its kind in understanding human psychological development, and was written at a time when most adults probably were sexually repressed, as well as viewing homosexuality as sinful. The later work of others, including Jung and Fromm, built upon his work, to help us understand the client’s presenting issue in a wider context. They widened our worldly view of the client by demonstrating how neurosis of the individual may also arise due to internal factors of the collective consciousness, arising from cultural and social heritage, or by external factors, such as how the client relates to the economic environment into which they are born. The work of the behaviourists also helps us to understand that any negative social conditioning also plays its part in understanding the client’s presenting issue. As a final note, we must remember that it is the job of the therapist to use the work of others as a tool to understanding the client’s own world in order to get enough understanding of the client’s perspective in relation to their own presenting issue. This understanding helps facilitate the client in coming to their own conclusions as to how best to tackle their own presenting issue, either by managing their condition from the Freudian perspective, or helping them change their own perspective and/or behaviour, as argued by the behaviourists.

liquids essays In this chapter we will see how water and its three states of matter play a big role in our daily lives. Even though all the three of matter of water have the same molecule, they can be different at some point. For example it takes more energy to change liquid water to steam than to melt ice at 0 c. The liquid water state lies in between solid and gas, but not midway between. But liquid is more similar to solid than to ice. Solid states is in terms of closely packed, highly ordered particles in contrast to widely spaced, randomly particles of gas. The liquid states between both, with more disorder arrangement than for the solid state and with some empty spaces. Those are just some of the important properties of liquids and solids. There are many solids and also gases at the atmosphere, but the liquid we most see is water. It is one of the most important substances on earth. It is important for sustaining reactions in our bodies that keep us alive. One water phase change is when you heat liquid water, what happens? First the temperature of the water rises. Now the motion of the water molecules increase, then when the temperature reaches 100 c, the water starts boiling, the temperature remains at 100 c. Until all the water has change to gaseous state. That is how liquid water can change from liquid to gaseous state. Another water phase occurs when liquid water is cooled to 0 c where the water starts to freeze. But until all the liquid water has change to ice, then the temperature starts decreasing again. Now the water is no longer liquid it has change states to solid ice. At temperatures below 0 c liquid water freezes and above 0 c ice melts. But water expands when it freezes. That is because ice at 0 c has a greater volume than one gram of liquid water at 0 c. 13.2 Energy Requirements for the Changes of State Changes of state from solid to liquid and from liquid to gas ...

Increasing unemployment in the city, lack of government action, institutionalised racism within the police force and general poverty led to the 1981 Toxteth riots, for which the area is probably most famous. Immigration to Toxteth took place from the 1950s to the present day, mostly from Africa and the Caribbean with relatively few from the Indian sub-continent. July 1981 saw the riots, in which dozens of young males caused a great deal of damage and many injuries. Poverty, unemployment, racial tension, racism from the local white population and hostility towards the police were largely blamed for the disturbances, which were among the worst scenes of unrest seen during peacetime in Britain at that time. Hundreds of people were injured, one man was killed by a police Land Rover, and countless buildings and vehicles were damaged. [4] Crime rates in Toxteth have been high for many years. As well as racial and civil unrest, vehicle crime has also blighted Toxteth. The highest-profile instance of vehicle crime in Toxteth came on 30 October 1991, when two children (nine-year-old Daniel Davies and 12-year-old Adele Thompson) were killed by a speeding Mazda sports car driven by 18-year-old joyrider Christopher Lewin on Granby Street. Adele died at the scene, and Daniel from his injuries a week later. Lewin was found guilty on a double manslaughter charge at Liverpool Crown Court on 24 September 1992 and sentenced to seven and a half years in prison, as well as being banned from driving for seven years. At the end of his trial, relatives and friends of the two victims pelted him with missiles and threatened to attack him. Five of them were ejected from the court. [5]

Meaning of Concepts - Essay Example The values must cover all of the possible outcomes of the event, while the total probabilities must sum to exactly 1, or 100%. For example, a single coin flip can take values ‘Heads or Tails’ with a probability of exactly 1/2 for each; these two values and two probabilities make up the probability distribution of the single coin flipping event. For example, a dart thrown at a dartboard has essentially zero probability of landing at a specific point, since a point is vanishingly small, but it has some probability of landing within a given area. The probability of landing within the small area of the bulls’ eye would (hopefully) be greater than landing on an equivalent area elsewhere on the board. A smooth function that describes the probability of landing anywhere on the dartboard is the probability distribution of the dart throwing event. The integral of the probability density function (pdf) over the entire area of the dartboard (and, perhaps, the wall surrounding it) must be equal to 1, since each dart must land somewhere. The normal distribution, also called the Gaussian distribution. In it each member of the family may be defined by two parameters, location and scale: the mean ("average", ÃŽ ¼) and variance (standard deviation squared) ÏÆ'2, respectively. Type I error, also known as an â€Å"error of the first kind†, â€Å"ÃŽ ± error†, or a â€Å"false positive†, the error of rejecting a null hypothesis when it is actually true. It occurs when we are observing a difference when in truth there is none. Type II error, also known as an â€Å"error of the second kind†, â€Å"ÃŽ ² error†, or a â€Å"false negative†, the error of failing to reject a null hypothesis when the alternative hypothesis is the true state of nature. In other words, this is the error of failing to observe a difference when in truth there is one. This type of error can only occur when the statistician fails to reject the null hypothesis. The

Is aspartame safe for you Research Paper Example | Topics and Well Written Essays - 750 words

Is aspartame safe for you - Research Paper Example Aspartame’s health concerns have been an issue of debate lately and this is why it is surrounded by controversies. In this paper the impact of Aspartame will be analyzed. Researches on Aspartame have revealed more than a few negative effects of regular usage of Aspartame especially the way it affects human brain’s cellular activity. In a research it was concluded that â€Å"excessive aspartame ingestion might be involved in the pathogenesis of certain mental disorders (DSM-IV-TR 2000) and also in compromised learning and emotional functioning† (Humphries et al., 2007). It happens so because of the highly toxic derivatives created in the body after the consumption of aspartame. Once ingested, aspartame breaks down intotoxic derivatives because of the presence of 50% phenylalanine, 40% aspartic acid,10% methanol/wood alcohol in its formula which formsformaldehyde (a colorless toxin) and a carcinogen called diketopiperazine in the body. (Humphries et al., 2007) Cumulatively, these toxins are responsible for affecting neurotransmitter regulation. In some studies, aspartame was regarded as the potential prompter, encourager or aggravator of risky pregnancy and cancer. The chemicals that break down after the use of aspartame pose immense threat to the developing fetus as well as the mother because it damages brain activity and can cause birth defects, reported Dr. Russell Blaylock (Raffelock, 2010). Just one can of diet soft drink containing aspartame can cause salient health-affecting symptoms in pregnant ladies such as nausea, headaches/migraines, numbness and dizziness to name a few alongwith increasing the risk of pre-mature baby birth by 78% (Chitty, 2011). Similarly, the risk of Parkinson’s, Alzheimer’s and ALS (Lou Gehrig’s Disease) can also considerably increase with daily intake of aspartame. (Chitty, 2011) This happens due to the formation of excitotoxins like Domoic acid and glutamate by phenylalanine that stimulates the brain cells negatively to
