This note amends the model of informational lobbying presented in Potters and van Winden (Public Choice 74:269–292, 1992). In the original article, the authors find that only separating and pooling equilibria exist when the cost of lobbying is intermediate and the policymaker’s prior favors the interest group’s preferred policy. However, we prove that a semi-separating equilibrium also exists under these conditions. Implications for lobbying behavior are discussed. 相似文献

Scholars do not usually test for the duration of the effects of mass communication, but when they do, they typically find rapid decay. Persuasive impact may end almost as soon as communication ends. Why so much decay? Does mass communication produce any long-term effects? How should this decay color our understanding of the effects of mass communication? We examine these questions with data from the effects of advertising in the 2000 presidential election and 2006 subnational elections, but argue that our model and results are broadly applicable within the field of political communication. We find that the bulk of the persuasive impact of advertising decays quickly, but that some effect in the presidential campaign endures for at least 6 weeks. These results, which are similar in rolling cross-section survey data and county-level data on actual presidential vote, appear to reflect a mix of memory-based processing (whose effects last only as long as short-term memory lasts) and online processing (whose effects are more durable). Finally, we find that immediate effects of advertising are larger in subnational than presidential elections, but decay more quickly and more completely.

This article analyses potential end-user copyright violations associated with peer-to-peer (P2P) file sharing and the anti-piracy efforts currently underway in order to tackle them. This article discusses international developments in terms of trends, issues and solutions aimed at addressing peer-to-peer file sharing of copyrighted material. First, the article introduces P2P file sharing, its increasing significance in the growing digital media economy, and the legal issues surrounding this topic. Next, the article provides a comparative analysis of global efforts and trends in preventing digital piracy by analyzing relevant legislation, case law and practices in multiple jurisdictions, including the United States, United Kingdom, France, Sweden, and Japan. In addition, the article reviews Hong Kong's current case law and proposed legal reforms including an analysis of their deficiencies with respect to addressing P2P copyright infringement. The article concludes with an analysis of existing trends in preventive measures against copyright infringement through P2P file sharing and suggests directions on future legal and non-legal measures that Hong Kong as well as the international community can take in combating digital piracy and copyright infringement through peer-to-peer file sharing. 相似文献

Abstract Eliciting useful and reliable disclosures from sex offenders is imperative for effective risk management. Responsiveness to accurate self-report by sexual offenders of their risky thinking and problematic behaviours ensures that offenders are dealt with at the correct risk level. This requires practitioners to use a range of constructive strategies and techniques for eliciting disclosures. Drawing on a recent study that investigated the nature and usefulness of disclosures, this paper explores the inherent challenges and identifies best practice in this important area of work. 相似文献

This research explores the implications of the growing use of the Internet to campaign and win elections in the United States. After exploring the historic assumptions and motivations behind the use of the Internet to campaign, the authors use election data from the 2006 midterm congressional elections and webpage ranking data from the leading web-based ranking service to assess the impact of Internet campaigning. The findings indicate that web presence is a significant predictor of the total votes candidates garnered in the 2006 congressional elections, even when controlling for variables such as funding, incumbency and experience. Further, the findings also suggest that, generally, Democrats had a stronger web presence than Republicans and this increased presence contributed to their success in the election. This research suggests that potential candidates need to be particularly concerned about the success of their websites and their popularity within the Internet community when running for office. 相似文献

Although some scholars suggest that racial/ethnic concordance between physicians and patients will do much to eliminate disparities in medical care, the evidence for concordance effects is mixed. Using nationally representative data with an oversample of blacks and Latinos, this study examines a variety of topics, including beliefs about and preferences for concordance, the effects of concordance on patient experiences, and interactions between expectations and experiences. The results point to the limited effects of concordance in general but illuminate for whom concordance matters most. The results encourage more nuanced and contingent theories. They suggest that racial/ethnic concordance holds little salience in the minds of most black and Latino patients and that discordance has little effect. Nevertheless, there is some evidence that concordance has a positive effect among those who prefer concordance-thus the apparent effects of concordance might reflect the effects of patient choice more than concordance per se. The conclusion sketches policy implications, including the merits of promoting concordance among targeted groups of patients, even in the absence of overall effects on disparities. 相似文献

The current study examined medical care need and utilization patterns among a substance abusing and recovering population (n = 876), investigating factors such as employment and drug use categories (e.g., pharmaceutical use, cocaine use, heroin use, alcohol use). It was found that those who were unemployed needed and utilized greater medical care than those who were employed. Results indicated that heroin, cocaine, and/or alcohol use was not predictive of medical care need or utilization, whereas pharmaceutical drug use was predictive of medical care need and utilization. Trauma and risky use of substances were not significant predictors of medical care need or utilization whereas the suicide severity composite was significant. Potential implications for misuse of medical services (e.g., to obtain pharmaceutical drugs of use) and federal medical care expenditure allocation are discussed. 相似文献
