Information campaigns are key elements of elections. Past research has established the importance of campaigns in informing and educating citizens, and ultimately strengthening participatory democracy. While the Internet has increased the possibilities to disseminate information campaigns and eased access to political information, it is still debated whether online campaigns are effective in stimulating political interest and participation among the general public. The issue is not only one of access, but also of use of information. The investigation of main effects of campaigns obscures the fact that citizens may not use information in the same way and reap the same political benefits. In this study, I examine the conditional effects of a new type of Web information campaign, Voting Advice Applications (VAAs), on the political engagement and electoral participation of citizens with varying levels of education. By investigating who benefits most from using these apps, I evaluate whether VAAs reinforce patterns of participation or mobilize new people in politics. Building on political behavior research, communication theory, and social psychology, I study the differential effects of VAAs with an innovative randomized field experiment design. The results confirm that VAAs can stimulate the political engagement of the public. However, there is no significant impact on electoral participation. In addition, the evidence shows that VAAs work differently for more or less educated citizens, and that the lower educated users benefit the most from VAAs as they become more interested in the election and more motivated to vote.  相似文献

Non‐state market regulation has become a central focus and continues to receive scholarly attention. The present paper provides an assessment of the conditions under which multinational firms join a multi‐stakeholder certification initiative. The cases of the Fair labor Association and 17 international sport footwear companies have been selected for this purpose. A Qualitative Comparative Analysis of the 17 cases is performed. The paper argues that the combination of sustained NGO pressure and public ownership of a firm is a necessary precondition for firms joining a multi‐stakeholder certification initiative. The theoretical and policy implications of this result are discussed.  相似文献

Although agricultural biotechnology has been a seminal reference point in risk perception studies, public awareness of their exposure to risk deriving from this new technology has been minimal at best. However, recent events indicate there may be growing public concern as new variations of this technology appear. Understanding what drives perceptions of benefits from the third generation of the agricultural biotechnology and what determines public worries are keys for the future of this technology. To this end, this study analyzes survey data from the midsouth region of the United States to construct four separate regression models of perceived benefits from and worries over plant‐made industrial products and plant‐made pharmaceuticals. Findings suggest that while prior experience with and knowledge about agricultural biotechnology has an impact on perceptions of benefits and worries, trust in farmers plays a highly important role in determining perceptions.  相似文献

Technology‐based economic development programs have become a salient feature of the state policy landscape since the 1980s. While much research exists on the topic, little attention has been given to the processes of policy formation. State programs have moved towards high technology areas emphasized at the federal level over the past decades, and nanotechnology became one of the latest targets. This paper examines the eight‐year process through which Pennsylvania adopted a “state‐wide strategy,” culminating in the Pennsylvania Initiative for Nanotechnology. In this process, programs that responded to the interests of multiple agents came first, and a state policy was formulated after the fact. This pattern of “rationalized policy formation,” as opposed to rational policy formation, may be more common than suspected. Its strengths and weaknesses in this Pennsylvania case are discussed.  相似文献

In order to guarantee a further successful functioning of the enlarged European Union a Federal European Constitution is proposed. Six basic elements of a future European federal constitution are developed: the European commission should be turned into a European government and the European legislation should consist of a two chamber system with full responsibility over all federal items. Three further key elements are the subsidiarity principle, federalism and the secession right, which are best suited to limiting the domain of the central European authority to which certain tasks are given, such as defense, foreign and environmental policy. Another important feature is direct democracy, which provides the possibility for European voters to participate actively in political decision making, to break political and interest group cartels, and to prevent an unwanted shifting of responsibilities from EU member states to the European federal level.  相似文献

Tetramethylene disulfotetramine (tetramine) is a rodenticide that has been banned for many years in China. Since 2005, inhabitants of a village in the Henan Province have been suffering from grand mal seizures. To investigate the possibility of tetramine as the cause, we developed a method to determine tetramine in human hair. Sample preparation involved external decontamination, frozen pulverization, and ultrasonication in 2 mL ethyl acetate in the presence of cocaine-d3 as an internal standard. The method exhibited good linearity; calibration curve was linear over a range of 0.1-20 ng/mg hair. The limit of detection for the assay was 0.05 ng/mg hair. Except for one subject (No. 4), all head and pubic hair samples were positive for tetramine. The concentrations of tetramine in pubic hair were significantly higher than those in the same subjects' head hair samples. Because of a long retention in body, segmental head hair analysis cannot provide an accurate exposure history of tetramine in the body.  相似文献

This paper uses a survey experiment to assess what individuals understand about election fraud and under what circumstances they see it as a problem. I argue that political parties are central to answering both these questions. Results from the 2011 CCES survey suggest respondents are able to differentiate between the relative incentives of Democrats and Republicans where fraud tactics are concerned, but whether voters see these tactics as problematic is heavily influenced by partisan bias. The results show little support for the notion that partisan ideology drives fraud assessments, and suggest support for the idea that individual concerns for fraud are shaped a desire for their preferred candidate to win. These results offer insights that might be applied more broadly to questions of perceptions of electoral integrity and procedural fairness in democracies.  相似文献

This article focuses on two groups of Southern Cone exiles' communities, Chileans and Argentineans, choosing to settle down in an atypical destination: the United States. After estimating some qualitative and quantitative findings, the article delves into the ways these communities settle down, remember their relationship with politics, maintain their connection with exiled fellow‐countrymen worldwide and perceive their national identity. By relying on an empirical, single‐case perspective, with no theoretical ambitions to extrapolate its conclusions to other contexts, this article examines the extent to which the conceptualisation of the exile and diaspora categories changes when applied to these two communities.  相似文献

Abstract: This study was based on a morphometric analysis of bite marks starting from the quantitative definition of the anterior teeth by the geometric acquisition of the “injuries,” using bite marks impressed on pig skin and plastic. Each mark was photographed and acquired. A dedicated program automatically supplied the values of the shape factors and the areas of the pattern geometric figures. The values obtained for the homologous samples were compared to the heterologous values. Statistical comparison was made of the sets by linear regression, determining the correlation coefficient and the determination coefficient for each value. Results showed only 4.8% and 2% of overlap between homologous and heterologous values. This study was carried out in attempting to quantitatively define the anterior teeth of the human dentition and the procedure described and the results obtained support the advantage of morphometric studies and computer‐aided programs in this study of bite marks.  相似文献
