However, rationally looking at how different the impact of foreign economic activities on China's economy and society is economic workers' main task. From 1982 to 2006, based on six categories of China's environmental indicators, the paper improves the entropy method to calculate the environmental pollution index which can represent China's overall environmental situation, uses the VAR model of the impulse response function and variance decomposition method to study the impact of foreign trade, FDI on China's environmental pollution in the long-term. The results show that, FDI and import trade is conducive to the improvement of the quality of our environment and export trade is the deterioration of our environment, "pollution haven" hypothesis is proved in China. Export trade is an important variable that aggravates environmental pollution.展开更多

We consider vehicle muting location problems, inventory-location problems and hub problems as a recent research field of discrete facility location problems according to literature from the last 10 years.展开更多

The findings show that the disclosure level has improved, but the overall level is still low and unable to satisfy information users; there is positive correlation between corporate size, industry type, accounting firm's type and corporate environmental dis-closure index. The companies of large scale and heavy pollu-tion and those audited by international "Big 4" and domestic "Big 10" accounting firms have a high level of environmental disclosure, while the profitability and financial leverage has no impact on the disclosure level. Finally some suggestions are put forward to establish environmental information disclosure sys-tem in China.展开更多

It focuses on the psychological process of the protagonist, Jim, by employing Freud's psychoanalysis to solve the puzzle surrounding Jim.展开更多

In their letter writing practice, English learners frequently commit all kinds of errors, quite a number of which are pragmatic errors. Since these errors seem to be quite correct in terms of grammar, they are likely to be ignored by both English learners and instructors. This paper attempts to expose such errors, analyze the causes of them and propose some tentative measures to prevent and to correct these errors.展开更多

This universal agreement necessitates an inclusion of a listening sub-test in any English proficiency test aimed at evaluating the candidates' comprehensive competence. Being a criterion-referenced proficiency test, both TEM4 and TEM8 (Test for English Majors: Band 4/8) contain a listening sub-test in their test battery. In this case, improving the authenticity of the listening sub-tests in TEM will no doubt be a contributory factor in improving the authenticity of the whole test. Based on the analyses of the current listening sub-tests used in TEM, the author concludes that there exists some inauthenticity in the test tasks. One source of the inauthenticity results from the input and the other from the test tasks which seem to be stereotyped in the current tests. In order to solve these two problems, the author suggests that major English varieties and limited-constructed-response question types be included in the TEM sub-tests so as to improve the authenticity of the tests and the accuracy of assessment.展开更多
