Efforts to promote and impose Mandarin Chinese as the language of instruction in ethnic minority schools in the Xinjiang Uyghur Autonomous Region, aimed at further integrating the state and raising regional educational and economic quality, have had mixed success. The 2004 plan to consolidate Han Chinese and minority elementary and middle schools and to make Mandarin the universal language of instruction in those schools is fostering an immersive second-language environment without prior preparation for students, bringing native speakers of Mandarin into unfair competition with non-native speakers. The increased focus on Mandarin has already had grave consequences for ethnic relations, especially in urban Uyghur schools, where the project is focused, while the mandate for change in educational curriculum and methodology has also been poorly planned and remains under-resourced, negatively impacting educational quality. The Chinese government has available to it other language policy solutions that are both more workable and friendlier to minority sensibilities.  相似文献

Criminologists have long debated the issue of how to define crime, and hence, the scope of criminological inquiry. For years, some critical criminologists have argued for expanded definitions of crime that include harmful behaviors of the state that may not be officially defined as criminal. Other critical criminologists have argued that existing legal frameworks may be used to study varieties of state crime, and that defining the harmful actions of the state as criminal is important to help mobilize public support for their control. In this paper, we first trace the historical development of these two perspectives, and then offer a tentative solution to the seeming tension between these two perspectives.  相似文献

This article explores the different and sometimes conflicting explanations of the success of the collective enterprises (town–village-enterprise) in China during the first phase of transition (1979–1995). It is argued that explanations, relying on cultural variables are not sustainable and this for two reasons. First, the importance of the collective enterprise is shrinking while the private sector is clearly on the rise. Second, other factors, referring to characteristics of the local and central political, administrative and economic environment, in which the Chinese enterprise has to (had to?) operate, provide for a sufficient explanation of the peculiar structure of the Chinese collective enterprises. These enterprises are seen as the result of ?bureau-preneurship’ because local bureaucrats were integrated in their management in order to pre-empt predatory behaviour and to facilitate the relationships with the central institutions. The article contributes to the property rights’ theory of the firm as it analyses an empirically very important case in which firms with unclear property rights and structures, apparently not conducive for incentives, might still be the most efficient option.  相似文献

In recent years, legislators in all fifty states have given grandparents rights to petition for visitation privileges with grandchildren that can be enforced over parental objections. Grandparent visitation rights reflect an effort to protect meaningful relationships children enjoy with nonparental caregivers, enlist the assistance of extended family when the child's nuclear family is disrupted, and defend the interests of grandparents themselves. This psycholegal analysis explores the direct and indirect consequences of grandparent visitation statutes for family functioning. Statutory provisions are summarized, and the effects of these statutes are evaluated in light of what is known about the role of grandparents in child development, how courts evaluate children's "best interests" in grandparent visitation disputes, and how these statutes can alter family functioning in informal ways. The authors conclude that there are risks as well as benefits to children and families in grandparent visitation statutes, and suggest directions for procedural and statutory reform.  相似文献

Kornai's thesis that shortage results from demand expansions bred by the soft budget constraint, derives from his implicit assumption that price regimes of input and output firms are different. Since any firm is both an input and an output firm, which discards the assumption as logically untenable, excess demand can only turn up because of lower than contracted inputs of labor and management that are not offset by an adequate downward adjustment of earnings. Expansions of demand that appear to be autonomous, are incited by uncertain deliveries of inputs, that is, by inefficiency (of output firms) as well. A by far the largest part of excess demand can be explained by state preferences for fast growth. As planners are more successful in generating investment, and the ensuing consumer, demand than in expanding production, shortage is inevitable regardless of the character of the firms' budget constraints.  相似文献
