Abstract The general purpose of this paper is to develop an explanation of how the macrostructural distribution of social resources affects the microsocial structure of personal social networks and, therefore, constraints on individual purposive action. Specifically, the paper attempts to provide a theoretical integration for two sets of recent findings; those noting status-related variations in personal network structures and those noting differential success in occupational attainment as a function of personal network structure and use. It is suggested that the effects of macrosocial and microsocial structure on purposive action in general can now be understood using a social resources perspective. 相似文献

Abstract This paper assesses the male contribution to contraceptive mismanagement and unwanted pregnancy. The subjects were 109 students at the University of Melbourne. A high incidence of risk-taking was reported, and almost one-fifth of the sexually experienced men stated that they had been involved in an unwanted pregnancy. A small group of these reported more than one such incident. The underlying reasons for poor contraceptive technique seemed to be related to two beliefs: that contraception is a female responsibility, and that sexual intercourse should be entirely spontaneous and unplanned. 相似文献

This article provides new evidence on the effects of recent debt‐relief programmes on different macroeconomic indicators in developing countries, focusing on the Heavily Indebted Poor Countries (HIPCs). The relationship between debt relief and institutional change is also investigated to assess whether donors are moving towards ex‐post governance conditionality. Results show that debt relief is only weakly associated with subsequent improvements in economic performance but is correlated with increasing domestic debt which undermines the positive achievements in reducing external debt service. There is also evidence that donors are moving towards a more sensible allocation of debt forgiveness, rewarding countries which have better policies and institutions. 相似文献

This paper applies concepts from the sociology and anthropology of organizations to understand limits to the implementation of a more effective safety culture in the workplace. It highlights unintended consequences of combining bureaucratic control and shared governance and identifies sources of inertia within already existing safety cultures. The data come from focus group interviews with workers in a research and development facility of a multinational corporation in the Western U.S. It is found that safety protocols, rules, and rhetoric, combined with efforts to give workers more responsibility for safety in the workplace, create tendencies toward worker alienation, shame with regard to injuries, complacency, and fear of bureaucratic processes. Therefore it appears that some efforts to create safety culture in the workplace may unintentionally undermine the goal of manufacturing safety. 相似文献

Economists have long conceptualized and modeled the inherent interdependent relationships among different sectors of the economy. This concept paved the way for input-output modeling, a methodology that accounts for sector interdependencies governing the magnitude and extent of ripple effects due to changes in the economic structure of a region or nation. Recent extensions to input-output modeling have enhanced the model's capabilities to account for the impact of an economic perturbation; two such examples are the inoperability input-output model( 1 , 2 ) and the dynamic inoperability input-output model (DIIM).( 3 ) These models introduced sector inoperability, or the inability to satisfy as-planned production levels, into input-output modeling. While these models provide insights for understanding the impacts of inoperability, there are several aspects of the current formulation that do not account for complexities associated with certain disasters, such as a pandemic. This article proposes further enhancements to the DIIM to account for economic productivity losses resulting primarily from workforce disruptions. A pandemic is a unique disaster because the majority of its direct impacts are workforce related. The article develops a modeling framework to account for workforce inoperability and recovery factors. The proposed workforce-explicit enhancements to the DIIM are demonstrated in a case study to simulate a pandemic scenario in the Commonwealth of Virginia. 相似文献

This article presents the findings of an intersectional study on migrant women on German television. Besides content and textual analyses, we conducted focus groups with audiences and interviews with migrant media workers. As the representation of Others was explored through the nodes of production, consumption, and identity, a complicated intersectional practice emerged. We found the televised representations of migrant women to be dominated by (often veiled) women as signifiers of non-integration but also by instances when gendered ethnicity was used as a marketable attribute. The audiences and producers employed various distancing strategies: they criticized specific programs for blatant stereotyping as much as didactic counter-stereotyping while downplaying systemic shortfalls of the coverage. These distancing strategies were intensified by the acceptance of individualized ideologies of success and commodified logics of media production. Ultimately, class appeared as the central demarcating category. On German television a problematic class distinction was articulated through ethnic and gender difference. Female migrants were often “othered” as lower-class. This class discourse absolved middle-class viewers and media workers from engaging in the systemic struggles over female/migrant identities, thus undermining the potential for gender and migrant solidarity and for the dynamic creation of cultural citizenship as a mode of belonging. 相似文献

The German Corporate Tax Reform Act of 2008 requires an adjustment of classic valuation concepts because it limits interest deduction from taxable income depending on the operating performance of the company. By using time- and state-contingent discount rates in a risk-neutral valuation with predetermined debt levels, a theoretically sound valuation result is obtained. However, a modified APV-concept which assumes deterministic debt over the planning horizon and constant leverage in the terminal value phase also yields consistent valuation results when two types of tax shields with different levels of risk are distinguished. 相似文献
