Why Do Chinese Students Choose To Study For First Degrees In UK Essay

Why Do Chinese Students Choose To Study For First Degrees In UK Universities - Essay Example Why Do Chinese Students Choose To Study For First Degrees In UK Universities? UK degrees are perceived to have greater career value than those offered in Chinese universities (Agelasto, 2001). Research question Why do Chinese students choose to study for first degrees in UK universities? Background This research study will basically involve the global expansion of Chinese students studying at UK universities. There has been declaration of policies in the UK for the expansion of both the absolute numbers of foreign students and their share of this huge Chinese market. Mainland China has been the largest component of this growth in the UK. Currently, they are by far the largest national group of overseas students in the UK, with numbers increasing by a factor of almost twenty over the ten years from 1994/5 to 2004/5. This study will focus on Chinese undergraduates, for whom the growth in numbers has been particularly marked – from 245 to 20,820 in that ten-year period (Denscombe, 2010). These Chinese students comprise of a major input generally to the UK economy and particularly to the financial health of universities. Strategies for the expansion of the market share will benefit from a vivid understanding of the kind of demand and the customers in the market. There have been no detailed studies assessing the relevance of various factors believed to influence students’ decisions to study abroad. ... foreign students, this study will also contextualize and develop our understanding of the processes which are involved in individuals’ decision-making (Agelasto, 2001). Other information The Chinese students’ decisions to study in the UK however, should be understood based on the relevant conditions in the home country, which will include the various university options available there. This study therefore will also briefly include Chinese students who have opted to study at their local universities, so as to have a whole picture of the involved decision-making process and its theorization. Two broad theoretical positions have been used to account for developments in patterns of educational enrolment and the choices that lie behind them: human capital theory and positional competition theory. The former argues that expansion of demand for education reflects increases in the skill levels demanded by the economy, with increasing components of technical and scientific know ledge that require longer periods of more advanced education and training, precisely the situation in contemporary China, and the basis of the policy of ‘massification’ of higher education. Rates of return on educational investment can be calculated and it is these that motivate social and individual decisions to invest in education (Hechanova-Alampay et al., 2002). Positional competition theory on the other hand, argues that the expansion of educational demand at increasingly higher levels of the system, as currently experienced in China, is the outcome of competition to increase one’s educational standing relative to others. The labor market and education relationship is not one of providing necessary technical skills, but one which is mediated by the use of credentials as a screening device

Highway Bound :: essays papers

Highway Bound Highway 40, is it a battleground or an interstate? It is a large mass of asphalt, dark rubber tire marks burnt into pavement, tons of fast moving steel, confusion, boiling anger, mental anguish and lost souls. I view the nations first federally funded interstate as a large mass of asphalt that stretches from North Carolina to California. I have personally spent many infuriating, intense and mentally draining hours on this highway, traveling in route between Durham and Raleigh. The memories of a thousand trips all seem to fuse into one long memory of roadwork, delays, chaos and horror. It takes strenuous efforts to confess and alleviate this burden from my shoulders. The nightmare begins as I navigate my pearl white Toyota Supra onto the Highway 147 onramp, denoted by an ever so familiar reflective green sign. My music blares a blissful tune as I sink the accelerator to the floor. Gaining speed, taking flight so that I can successfully merge into the never-ending column of vehicles racing towards their separate destinations. As I merge off of the onramp and into chaos I look cautiously over my shoulder, checking to make sure I am clear to get in. A minivan the color of the darkest midnight is the only obstacle in view. I merge successfully deciding the slow moving vehicle is well out of danger. No sooner do I slide securely into my lane upon the black asphalt than I notice that this family transport of safety is not really that, but a marauding mother hauling her troops into combat. The dark figure of the van grows larger and larger until it appears I am merely an obstacle meant to be trampled. I look down and realize that we are reaching sp eeds of eighty miles per hour, yet this minivan has virtually become a part of my bumper. I flash questioning glances behind me trying to predict the mad woman’s intentions. Unable to bring solace to the growing war behind me, I face forward concentrating on simply keeping my car between the bright, pure white line running broken down the highway. I keep my car within a few feet of the one in front of me, trying not to infringe upon danger but at the same time trying to keep mother murder behind me from laying on her horn.

Test Puzzle

Instructions In a logic puzzle you are given a series of categories, and an equal number of options within each category. Each option is used once and only once. Your goal is to figure out which options are linked together based on a series of given clues. Each puzzle has only one unique solution, and each can be solved using simple logical processes (i. e. educated guesses are not required). A custom-labelled grid is provided for every puzzle, like the one you see to the right.The grid allows you to cross-reference every possible option in every category. You can eliminate pairs you know aren't true with an X, and pencil in pairs you know are related with an O. If you know, for example, that Lauren wasn't born in 1961, you can add an X in the box where the Lauren column and 1961 row meet. Similarly, if you know that Bryant was born in 1971, you can add an O in the appropriate box.Furthermore, since every option can only be used once in any given puzzle, you can eliminate the four ot her options for Bryant in that category (1937, 1946, 1961, 1975) and the four other options for 1971 (Anahi, Jayden, Lauren and Nikolas). Continue doing this for every clue you're given. Eventually you will have filled in enough X's and O's on the board that you will then be able to use simple logic to deduce the solution to the puzzle. For example, if A = B, and B = C, then A must equal C.Similarly, if A = B, and B =/= D, then A must not equal D.

Spirituality How the belief in God or Gods plays a pivotal role in The Odyssey and The Godfather epics Free Essay Example, 1500 words

Spirituality: The Belief in God or Gods as it Relates to The Odyssey and The Godfather The concept of god is a way of describing a power within a story that is outside of human control. This power can also be ascribed to a human within a story, giving them a control that is beyond what is normally within the frame of human control. In The Odyssey, Odysseus experiences a series of encounters with god or godlike powers that he must overcome to continue on his journey. In the film The Godfather (1972), the Corleone family becomes the embodiment of godlike powers, their spiritual life enhancing the nature of their own power through events of violence. The nature of myth and the way in which it defines powers within the supernatural experience can be seen in the nature of both epics, their respective contemporary cultures reflected through the defined powers that are beyond that of the human world. The Greek mythologies are designed with the expression of god embodying exaggerated human failures of character. The gods of the Greeks were petty, selfish, and full of hubris, even though they looked down on humans and punished them for the same kinds of characteristics. We will write a custom essay sample on Spirituality: How the belief in God or Gods plays a pivotal role in The Odyssey and The Godfather epics or any topic specifically for you Only $17.96 $11.86/pageorder now The stories of the gods created a framework in which the nature of mankind was discussed, the challenges that they presented part of the explanation that helped ancient man to understand his world. Both the internal world of men and the external world of nature, its power and imposing destruction, was explained through the mythologies. Myth was the way in which the unknown was approached, mankind needing answers to questions that were often beyond the scope of any technology that could be defined. The nature of The Godfather films is similar in that a larger, mysterious organization was given context and explanation through the vision and myths created by Mario Puzo, the writer of the novel. The novel was then translated into film by Francis Ford Coppola in which not only the myth of the Corleone family was brought into the public consciousness, but the film, itself, gained mythic status. According to Horrocks, The Godfather (1972) â€Å"peels awa y the veneer of civilization, revealing to us a culture steeped in blood and death† (79). The myth of the masculinity of the ‘male corporation’, also found extensively in Western genre films, becomes more organized and brought into the modern context through the ‘mafia’ films as â€Å"the shrinking from domesticity and the emphasis on violence and death† creates a resource in which power is shifted to something that is more mythic and grandiose (Horrocks 70).
