This research concerns how costs and benefits affect the voluntary provision of threshold public goods. Cadsby and Maynes (J. Public Econ. 71:53–73, 1999) hypothesized that the difference between the value and cost of such a good, its net reward, influences the likelihood of provision. Croson and Marks (Exp. Econ. 2:239–259, 2000) focused on the ratio of group payoff to total cost, the step return. We find that step return is the best predictor overall, although net reward has some impact, negatively affecting the probability of provision with inexperienced participants and positively affecting it with experienced participants. 相似文献

This article examines German national parties' use of the Internet in the 2002 federal election. Its main goals are to determine what the parties were doing in their online campaigns and how far their use of the Internet can be understood in terms of two party-specific variables – organisational size and primary goal. These questions are of significance given the relatively limited study of parties' use of the net in Germany in the comparative literature on this topic. Also, research on parties' use of the Web across countries has suggested that while context does produce differences in approach, partyspecific factors also play a major role in determining online strategy. The article attempts to investigate these questions systematically by examining nine German parties' use of the Internet (specifically websites, e-mail, and intra-nets) using questionnaire data from national party personnel and content analysis of web pages. Our findings show that while the divide between major and minor parties can be seen quite clearly in the German context in terms of website quality and visibility, evidence to support the impact of party outlook in shaping parties' online strategy can also be found. In addition, the study reveals that major parties are now beginning to take the Internet very seriously as a communication tool, particularly in terms of election campaigning. 相似文献

Scientists, policymakers, and medical professionals alike have become increasingly worried about the rise of antibiotic resistance, and the growing number of infections due to bacteria like Clostridium difficile, which cause a significant number of deaths and are imposing increasing costs on our health care system. However, in the last few years, fecal microbiota transplantation (FMT), the transplantation of stool from a healthy donor into the bowel of a patient, has emerged as a startlingly effective means to treat recurrent C. difficile infections. At present, the FDA is proposing to regulate FMT as a biologic drug. However, this proposed classification is both underregulatory and overregulatory. The FDA''s primary goal is to ensure that patients have access to safe, effective treatments—and as such they should regulate some aspects of FMT more stringently than they propose to, and others less so. This essay will examine the nature of the regulatory challenges the FDA will face in deciding to regulate FMT as a biologic drug, and will then evaluate available policy alternatives for the FDA to pursue, ultimately concluding that the FDA ought to consider adopting a hybrid regulatory model as it has done in the case of cord blood. 相似文献

AbstractForeign direct investment (FDI) can deliver benefits beyond the provision of capital, such as efficiency gains. We argue that the theorised positive effects of economic linkage are reduced when linkages are based on natural resources. Domestic elite coalitions supporting reform are also weaker in countries with extensive natural resources. Kazakhstan and Azerbaijan have high-value natural resources and significant FDI, making them most likely cases for reform. Kyrgyzstan is a contrasting case as it has few natural resources. We find that the institutional reforms we would anticipate because of linkages have not occurred and those that exist are often cosmetic. 相似文献

The study examines narrative data from in-depth, semi-structured interviews with 25 women in a medium security prison with the hope of deepening the knowledge base related to women’s beliefs about their mental health problems, mental health care during incarceration, and especially their experiences with psychotropic medication. The findings highlight the functional role of psychotropic medication in the lives of incarcerated women, while also emphasizing problems with limited access to prescribers, preferred medications, and other forms of mental health treatment. Trauma, substance use, and the impact of medication use on sense of self all emerged as interfacing with quality of life. 相似文献

This paper identifies the business constraints that are most binding for firm performance. Using panel methods on novel quarterly Ugandan business climate data, we exploit perceived changes in business climate constraints to account for changes in firm performance. Not all identified constraints are binding for firm performance. Macroeconomic instability, demand stability, access to finance, corruption/bribery, and weather variability are found to be binding constraints. Firms’ expectations about future performance outcomes are associated with current perceptions about these constraints, alleviating endogeneity concerns to some extent. While taxation constraints are usually highly ranked, we do not find evidence linking them to firm performance. 相似文献

This article suggests that the futuwwa articulated by Shihāb al-Dīn ‘Umar al-Suhrawardī (1144–1234) created a paradigm of exclusion and inclusion for late medieval Anatolian urban confraternities. This largely faith-based construct was developed in the Seljuk capital of Konya and reduplicated in futuwwa treatises that were composed in Armenian, Persian and Turkish in the region. The multi-cultural, multi-lingual, multi-religious cultural environment of the late medieval Anatolian city provided an opportunity and, possibly, a necessity for futuwwa associations to draw boundaries around their associations. It is uniquely through the study of the city as a unit that we will be able to understand the huge cultural and religious transformations that were taking place in Anatolia during the late medieval period. Study of futuwwa associations as regulating urban populations provides a window of insight into the ways in which groups of men attempted to define themselves in juxtaposition with others. 相似文献
