China’s State-Owned Enterprises (SOEs) traditionally have been governed by the Communist Party. Privatization has brought greater numbers of investors who have a stake and demand a voice in how SOEs are managed. Three traditional governance perspectives are agency theory, resource dependence, and institutional theory, but China’s transition introduces several additional governance approaches. Are “capitalism with Chinese characteristics” and “bureaucratic entrepreneurialism” paradoxes? Based on initial interviews of SOE executives, a survey of top managers and board chairs of listed companies, and subsequent interviews and observations in select case companies, this paper develop a taxonomy of SOE governance that now exists in China. Two of the approaches represent the extremes of the old state-centered regimes and the new shareholder-centered regimes. Considering China’s historical and cultural contexts coupled with its current stage of economic transition, two additional approaches to corporate governance are to have a vacuum as neither the state nor shareholders dominate or – in unique contrast to other countries – a hybrid of both. 相似文献

This study examines youths' experiences of loneliness and community connectedness in relation to seven domains of subjective quality of life among pre-adolescents, early adolescents, and middle adolescents. Participants consisted of 464 youth, ranging in age from 11 to 17 years, from two rural towns. Youth reported on their subjective experiences of loneliness and their perceptions of their community environments (neighbourhood and school). Hierarchical regressions indicated the importance of loneliness in accounting for subjective quality of life for early adolescents, and less so for middle and pre-adolescents. Community factors significantly accounted for additional variance in pre-adolescents' reports of their quality of life, compared with early and middle adolescents' reports. Discussion highlights the importance of understanding the determinants of quality of life from an individual, community, and developmental perspective. 相似文献

Objective. This article examines long-term trends in the environmental voting behavior in Congress and attempts to identify the factors that account for racial differences in voting patterns. Methods. Hypotheses about the various possible influences on environmental voting behavior are tested using longitudinal analyses and path analysis techniques. Results. Findings indicate African American members of Congress have been consistently more supportive of proenvironment legislation than either Republican or Democrat colleagues from 1981 to 1998. The data further suggest that much of these overall differences are explained by an especially large racial gap in proenvironmental voting among members from the South. Although such a gap among members from outside the South is eliminated by controlling for ideology and other variables, it remains substantial among Southern members. Conclusions. Based on the strong and consistent support for environmental legislation by African American members of Congress in the past, we expect significant racial differences in environmental voting to endure. Although results suggest that ideology plays a partial role in explaining such differences, future research will be needed to identify the reasons for the especially large racial gap in proenvironmental voting among members from the South. Given the growth in their numbers, their relatively safe seats, and their potential to chair important committees as they gain seniority, we expect African American legislators to play an increasingly important role in shaping and deciding the fate of national environmental policy in the future. 相似文献

Several metbods have been proposed to weight decision criteria. In this field study a decision group, like that used by public agencies, was formed to establish project priorities. The decision group used a variety of criteria weighting methods to study how these methods influence the magnitude of the weights assigned by members of the decision group. Direct criteria weighting methods (scaling, rank-weight, point assignment and odds procedures) and an indirect approach (weights derived from hypothetical projects) were considered. The study compared the methods in terms of the magnitude of the weights assigned, the variance in weights among members of the decision group, and the similarity of the decisions based on weights assigned by each method. The time to apply each method and the preferences of the decision makers were also determined. The linear rating scale that defined the meaning of scale increments, called an ‘anchored ratin scale’, was found to be favorably received and efficient and led to the most defensible decisions. 相似文献

This paper is concerned with the problem of allocating a fixed number of trials between two independent binomial populations with unknown success probabilities θ1 and θ2, in order to estimate θ1 - θ2 with squared error loss. Introducing independent beta priors on θ1 and θ2, a heuristic allocation procedure is introduced and compared both with the optimal and with the best fixed allocation procedure. Numerical and asymptotic results of these comparisons are given and seem to indicate that there are situations when the best fixed allocation procedure performs almost as well as the optimal procedure. 相似文献

The manual dexterity of the oriental female is famous all over the world. Her hands are small and she works fast with extreme care. Who, therefore, could be better qualified by nature and inheritance to contribute to the efficiency of a bench assembly production line than the oriental girl. 相似文献
