The rapidly changing political, economic, and security policies in the Soviet Union and Eastern Europe in late 1989 and 1990 have added to the complications faced by Chinese leaders since they decided to suppress the unprecedented large-scale pro-democracy demonstrations in Chinese cities in spring 1989. These changes had an obvious “ripple effect” in China, encouraging prodemocracy forces and alarming Chinese leaders. They attracted strong positive attention from the developed countries of the West and Japan, and international financial institutions and businesses. This came at the indirect expense of China. And they accelerated changes in world politics (especially in U.S.-Soviet relations) and in the politics of government decision making in the West that promised to reduce China’s relative influence in world affairs in the 1990s. The prospect of reduced influence abroad and curbed economic contacts did not appear to be sufficient cause for Beijing leaders to markedly change existing policies. Chinese leaders in mid-1990 appeared focused on issues of internal political power at a time of leadership transition. Significant changes in policy appeared most likely to await leadership changes as Deng Xiaoping and other aged leaders die or are incapacitated.  相似文献

One-hundred and seventeen college-aged women at varying risk for developing bulimia answered a number of questions addressing their attitudes toward and comfort with sexuality as well as their sexual and contraceptive history. Risk for developing bulimia was unrelated to sexual attitudes and weakly related to greater comfort with sexuality. High-risk women reported first engaging in intercourse at earlier ages and were also more likely to engage in risky contraceptive behavior than their lower risk counterparts. Despite their tendency to report a greater number of previous sexual partners, high-risk women currently engaged and expected to continue to engage in sex less frequently than lower risk women. Taken together with previous findings, results suggest that the relationship between risk for bulimia and certain patterns of sexual behavior reflects a general cycle of impulsive and controlling behavior exhibited by high-risk women. Limitations and implications of the present study are discussed.Half-time Editorial Assistant, Journal of Social and Clinical Psychology. Quarter-time research assistant, University of Kansas.

The prospects for European Union citizenship are sometimes discountedby reference to homogeneity in the United States compared todiversity in the European Union. This article suggests thatthere may be more similarities between the two systems thanis sometimes supposed by many observers. Even though there areimportant differences, both systems have had to address similarquestions about how to combine the benefits of integration andthe protection of rights. In discussing the common and divergentfeatures, the author argues that comparison also reveals thepossibility that it is diversity, not homogeneity, that is necessaryto the protection of citizenship's rights.  相似文献

Generous Commonwealth funding before self-government in 1989 meant that the ACT enjoyed high government expenditures and low taxation compared with the states. Self-government meant a transition to normal state funding, ultimately involving substantial reductions in Commonwealth grants. Successive governments aligned taxes with other jurisdictions, but failed to reduce expenditures, which remained well above Commonwealth Grants Commission (CGC) assessments of levels necessary to provide a standard level of services. The fiscal position — however measured — has worsened. The transition to normal funding has been unsuccessful and, without the necessary adjustments, a heavy burden will be placed on future Canberrans.  相似文献

"We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable rights, that among these are life, liberty and the pursuit of happiness. That, to secure these rights, governments are instituted among men, deriving their just powers from the consent of the governed." These words from the Preamble to the Declaration of Independence, proclaimed a conviction and announced a challenge for our newly formed nation. Today, they either stir the American heart with pride or generate nostalgia for a time when any truth was self-evident and the right to life was deemed inalienable.  相似文献
