A defining feature of the modern US Senate is obstruction. Almost all pieces of legislation considered in the Senate are affected either directly or indirectly by obstruction. Obstruction takes many forms in the modern Senate, but one of the most prevalent, yet least studied, is the hold. Using a newly created dataset on Republican Senate holds, we cast light on this important practice. Our results suggest that a variety of factors including timing, party status, and a senator's voting record are related to both the prevalence of holds and the success of legislation subject to holds in the Senate. 相似文献

There is an urgent need for consistent data sharing policies that promote the advancement of science while respecting the values and interests of those providing their genetic data for research. Responding to the article of Jalayne J. Arias, Genevieve Pham-Kanter, and Eric G. Campbell, ‘The Growth and Gaps of Genetic Data Sharing Policies in the United States’, this commentary further explores the challenges of human subjects’ protection in existing data sharing policies. We will elaborate on the need for data sharing policies to accommodate variation in individual and group preferences around data sharing and privacy concerns by comparing our previously published data on patients’ and parents’ consent to data sharing and attitudes about privacy to data from focus groups with HIV-positive, underserved individuals who were asked about their willingness to participate in genetic research and share their data broadly. These studies support the observation of Arias, Pham-Kanter, and Campbell that researchers, and funding agencies will need to balance the privacy interests of groups as well as individuals in future genomic data sharing policies. 相似文献

Intensifying labour conflict in China has posed a serious challenge to the industrial relations system. Under growing pressure, the Chinese government has sought to reform the system but the results are meagre. Among the supposedly successful cases, the development of collective bargaining in Wenling, Zhejiang province has been hailed as a model of labour relations to be replicated elsewhere. Based on a detailed case study of Wenling, this study aims to analyze the process whereby local government reconstructs the industrial relations system by organizing and incorporating the interest of employers and workers, leading to regularized wage growth and reduced labour dispute. This restructuring, the study argues, is designed to create a functional state corporatist system by means of expanding union representation and instituting tripartite collective bargaining. However, the tensions in the state corporatist structure may still undermine any attempt by the government to reconstruct industrial relations. 相似文献

Statistics describe realities, but they also shape them, since they are used to design or support policies. As such accurate statistics are important. Using the agricultural sector in Rwanda as a case study, we demonstrate that dubious statistics can spread quickly. According to data from the Food and Agricultural Organization (FAO), yields have increased by 60 per cent since the implementation of large scale agricultural reforms, while other datasets point towards more modest gains. Yet, estimates in line with those of the FAO dominate the official discourse. We suggest that the discrepancies between datasets may be explained by the difficulties of collecting accurate agricultural statistics combined with an incentive to overestimate yields to show that the reforms have worked. 相似文献

This paper offers new evidence regarding the impact of public spending on the supply of leisure services on citizens’ spare-time quality of life. Using data from 103 Italian capital municipalities covering the period 2007–2010, the analysis revealed that public spending on leisure impacted spare-time quality of life in various ways, depending on the category of spending. Spending for tourism essentially followed an upward path, linearly enhancing citizens’ spare-time quality of life. Surprisingly, municipalities’ spending on sport- and culture-related services had a non-linear impact. Hence, spending on sports within a maximum threshold reveals a positive impact on spare-time quality of life, whereas passing over a minimum level of public spending for culture-related projects had a positive effect. This paper provides helpful suggestions for policymakers who approach decisions that address whether it is worth spending on leisure, which is typically a non-basic need but one that must be properly satisfied by municipalities in today’s service-based society. 相似文献

Information and communication technology have played an important role in the tactics of uprisings against non-democratic regimes worldwide. However, there has been little attention paid in studies so far of how authorities in those countries employ such information and communication technology. In this article we examine the evolution of such tactics as employed by one of the most ingrained authoritarian regimes—that of Belarus—during the decade 2001 to 2010. The political opposition's responses to the authorities' countermeasures are also investigated, followed by an analysis of the co-evolution of these opponents' tactics. 相似文献
