The New Chinese Migration is frequently contrasted to the earlier 19th century mass migrations in terms of its origins (urban vs rural), migrant types (students and professionals vs coolies) and destinations (developed vs developing countries). A significant component of this new migration from the PRC however, continues to originate from the qiaoxiang – the emigrant‐sending areas of the 19th century migrations. Based on an extensive review of the literature on the old and new Chinese migration, as well as several years of fieldwork in the major rural sending areas or qiaoxiang of China, we examine the continuities between the new qiaoxiang migration and the old, and propose a qiaoxiang migration model of the entrepreneurial nature of the migration enterprise to account for the sustained and global character of the mobility generated.  相似文献

This study proposed and tested a model of factors influencing the effectiveness of Local Emergency Planning Committees (LEPCs). Data were collected from the chairs of Michigan LEPCs, who were asked to provide information about their LEPCs’staffing, activities, resources, and team climate, as well as information about community hazards and relationships with other organizations in their communities. The model was partially supported. As hypothesized, team climate substantially mediated the relationships between an LEPCs effectiveness and many of the attributes of its internal structure and external environment. In addition, three (emergency planning resources, community support and LEPC staffing and structure) out of four categories of variables hypothesized to influence team climate were, in fact directly related to it. There were two major inconsistencies with the model. First, two types of emergency planning resources were found to have a direct influence on LEPC effectiveness rather than an indirect effect mediated by team climate. In addition, hazard vulnerability was hypothesized to have a direct effect on team climate, but the data showed this relationship was mediated by community support and by LEPC staffing and structure. A revised model was proposed that suggests ways in which members can change the structure of an LEPC and strategies to enhance its effectiveness.  相似文献

我是今年回国的留学生。看了《我遇上了“抠门”老板》中讲的老板的事,觉得还真是那么回事,我的台资老板也是这样的……本以为自己是美国MPA,在国内找个称心的工作不成问题,没想到回来不到半年,非但没有找到好工作,还遇上了“抠门”老板。现在我的梦想完全破灭,连自信心都快湮没了,感觉就像一条在岸上搁浅的鱼……  相似文献

In the early period of the Labour Government of 1945–1951, the British economy underwent a serious crisis, one dimension of which was a severe labour shortage in sectors identified as essential to national economic recovery. In an attempt to resolve this problem, the Labour Government recruited foreign labour from a number of different European sources, but was also required to gain the consent and co‐operation of the trade union movement for this initiative. This paper documents and explains the evolution of the policy of the Trades Union Congress towards this initiative, and the opposition that this stimulated within the trade union movement.  相似文献

ABSTRACT

This phenomenological study used individual, semistructured, face-to-face interviews to explore motherhood experiences among 15 women receiving public assistance in a large urban area on the West coast. A primary phenomenon observed was that motherhood was described as an experience of identity change, with resulting emotional, behavioral, and sense-of-self changes. Within this broad theme, two categories emerged: the experience and process of change, and consequences of change. It was concluded that motherhood may serve as an important catalyst for change in some women and that the context of poverty is essential for understanding the motherhood experience. These results suggest that interventions aimed at leveraging emerging motherhood identities may be beneficial in setting women on the path out of poverty, drug addiction, and incarceration. Future research should examine the consequences of maternal change within the specific context of the stages of change documented in the recovery process from drug addiction.  相似文献

State environmental agencies in the United States are charged with making risk management decisions that protect public health and the environment while managing limited technical, financial, and human resources. Meanwhile, the federal risk assessment community that provides risk assessment guidance to state agencies is challenged by the rapid growth of the global chemical inventory. When chemical toxicity profiles are unavailable on the U.S. Environmental Protection Agency's Integrated Risk Information System or other federal resources, each state agency must act independently to identify and select appropriate chemical risk values for application in human health risk assessment. This practice can lead to broad interstate variation in the toxicity values selected for any one chemical. Within this context, this article describes the decision‐making process and resources used by the federal government and individual U.S. states. The risk management of trichloroethylene (TCE) in the United States is presented as a case study to demonstrate the need for a collaborative approach among U.S. states toward identification and selection of chemical risk values while awaiting federal risk values to be set. The regulatory experience with TCE is contrasted with collaborative risk science models, such as the European Union's efforts in risk assessment harmonization. Finally, we introduce State Environmental Agency Risk Collaboration for Harmonization, a free online interactive tool designed to help to create a collaborative network among state agencies to provide a vehicle for efficiently sharing information and resources, and for the advancement of harmonization in risk values used among U.S. states when federal guidance is unavailable.  相似文献

Although fundraising organizations in the third sector have gone through a progressive professionalization process, it remains unclear whether this development has led to any financial benefits. This article focuses on the question of whether or not it pays off for fundraising organizations to invest in professionalization. The data for this study come from 165 organizations representing 45 percent of the Swiss fundraising market. We first propose the term “organizational fundraising capability” as a new construct for measuring the degree of professionalization and rationalization in fundraising management. We then analyze its relationship to overall net revenue from donations as well as the growth of net revenue from donations. Our analysis indicates that, in addition to organizational size measured by total revenue, revenue share from donations, and expansion strategy, fundraising capability makes an important contribution to explaining both an institution's net revenue from fundraising and the level of increase in net donations. The consequences for the development of professionalization and rationalization in fundraising are discussed.  相似文献
