Do voters like the party they already agree with or do they agree with the party they already like? Previous studies have suggested a link from preferences to perceptions. However, such a causal link has not been convincingly demonstrated. Most issue voting studies have adopted the basic premise of spatial models of voting—that voters compare parties’ positions with their own ideal points and apply a rule to choose among these parties. Drawing on a natural experiment, this study shows that perceptual agreement between parties and voters is endogenous to voters’ party affect. We use the murder of a Dutch politician amidst the data collection period of the 2002 Dutch election study. The death increases respondents’ feelings for his party without providing information about its issue stances. This upward shift in feelings translates into a significant increase in the perceived level of proximity with the party. The design also allows us to explore the mechanism bringing parties and voters closer. Rather than taking up the party’s stances, voters move a party’s positions closer to their own views when their feelings for that party increase. The findings challenge established assumptions about the theoretical underpinnings of spatial models of voting. They support classic notions of voter projection and lend credence to recent theories of attitudinal change, which are based on coarse thinking and uninformative updating. 相似文献

In this contribution we demonstrate how the usage of panel data offers possibilities for testing new hypotheses in a research tradition with a long history in political science. Focusing on citizens’ transitions in and out of voluntary associations, we tested four possible explanations for the well-documented correlation between civic engagement and political socialization. Two are due to self-selection effects (pools of democracy), and two are due to socialization effects (schools of democracy). Our analyses offer little support for the idea of voluntary associations playing a major role in political socialization processes: our latent growth curve models showed no or very little increase of political discussion, interest, efficacy, and action among those who became actively involved in voluntary associations. In contrast, we found convincing evidence for our pools-of-democracy hypotheses, and the self-selection turns out to be a double-edged sword: politically engaged citizens are more likely to join voluntary associations and less likely to leave them. These findings challenge the conclusions of many studies based on cross-sectional data. 相似文献

The dynamics of doping: Lance Armstrong,the United States Anti‐Doping Agency and the regulatory governance of professional cycling 下载免费PDF全文
On 10 October 2012, the United States Anti‐Doping Agency published an investigative report on the use of performance‐enhancing drugs by professional cyclist Lance Armstrong. The report paints a disconcerting picture of the doping program that Armstrong and his US Postal Service professional cycling team managed to carry out for several years, despite being subject to many inspections. It contains a wealth of unique empirical data, including a large number of affidavits. In this article, we use this data to answer the question of how Armstrong was able to prolong prohibited behavior. In doing so, we focus in particular on the interactions between Armstrong and the many doping inspectors he encountered. Our analysis results in a variety of answers to this question. First, inspectors were confronted with an inspectee who behaved as an “amoral calculator” and acted strategically. The strategies of inspectors were not adequately attuned to such behavior. Second, the team's internal professional control was neutralized by various factors, including its strict hierarchy and the many friendships within the team. And, finally, the environment created strong incentives to start doping and subsequently deny doing so. We argue that the dynamics underlying doping necessitate a combination of measures to regulate the use of performance‐enhancing drugs in the field of professional cycling and beyond. 相似文献

With pressure on universities to better contribute to society, academic entrepreneurship is an increasingly recognised source of new knowledge and technologies as well as being a driver of the movement to a knowledge society. However, whilst growing, the level of academic entrepreneurship in Europe is still relatively low. Two reasons that are factors influencing this are inhibitors (barriers) and facilitators (drivers), however the understanding of how their interplay influences academic entrepreneurship, particularly across different context is lacking. For this reason, this study focussed on two environmental settings, European regions and countries, seeking to understand if it is the hurdle (barrier) or (and/or) tail-wind (drivers) that most impacts academic entrepreneurship and how does the regional or national context influence this. An online survey was translated into 22 languages and undertaken in 33 countries in Europe and the European Economic Area. From the original data set, 12 countries in four European regions provided a sample of 2925 responses, with a second step to focus on four ‘lead’ countries within those regions. The results show that there is a significant difference in the university-business cooperation barriers and drivers that effect academic entrepreneurship in the European regions. Furthermore, different barriers and drivers were found to significantly affect the four lead countries with barriers and drivers being able to provide a good explanation of the extent of academic entrepreneurship in the UK and Germany, and a limited explanation of entrepreneurial activity by Spanish and Polish academics. Overall the article contributes to the literature of resource-based theory and also the understanding of factors influencing European academic entrepreneurship. 相似文献

The little versified treatise on the elements of Buddhist logic, often referred to as the Hetucakra?amaru, is usually attributed to Dignāga. It is only available in a Tibetan translation and quotations from a few of its verses are extant in Sanskrit sources. On the basis of a novel interpretation that is based on a critical edition of the text, we argue that there is a good reason why its title was Hetucakra?amaru - a ?amaru is a two-headed drum. The “heads” of the drum are circular and they refer to the sapak?a and vipak?a conditions of the logical reason (hetu). These “wheels” can be turned clock-wise and counter clock-wise. The nine positions that are located on the wheels do remind one of a dharmacakra, which has a center and eight positions that are placed around it as if it were a compass. We illustrate our interpretation of the text by means of various diagrams. 相似文献

The trade in caviar has a rich and colorful history, influenced over thousands of years by many cultures, societies and in the last decades by regulation. The value of caviar is historically discovered in the context of social change, political relationships and environmental change. The role of organized crime is described, as the scarcity of caviar has offered the unique opportunity to fish illegally, smuggle and trade contraband to mainly European countries with millions in profits. This study highlights that these criminal networks manifest themselves at all levels of the trade: from the poaching areas where organized criminal groups cooperate with law enforcers and possess top-notch equipment to major smuggling operations in the hands of sophisticated criminal networks. Although due to overexploitation ‘wild caviar’ is increasingly difficult to obtain, the demand in the context of exclusivity and scarcity remains intact by the upper class society desire for edible gold. 相似文献

Since the development of the Violence Risk Appraisal Guide (VRAG), one of the most widely used actuarial risk assessment instruments, numerous replication studies have shown its usefulness in predicting (violent) recidivism among various offender populations. It is not clear, however, whether these findings can be generalized to forensic psychiatric patients admitted to a medium security forensic psychiatric unit in the Flemish part of Belgium. Therefore, the main aim of this study was to test the predictive validity and reliability of the VRAG in a sample of 191 Flemish medium security patients. The mean follow-up period was 2.4 years. Contrary to the expectations, the VRAG was unable to significantly predict any kind of outcome. Possible explanations are discussed and further research with the VRAG in Flanders, and its recently revised version, is recommended. 相似文献
