经过一百多年的发展,利用多导仪进行犯罪心理测试不同程度地被50多个国家所接受,但对于它的质疑并没有停止过。在对近年来国外关于准绳问题测试和隐蔽信息测试的评价与研究成果进行罗列及评价的基础上,可以发现,未来犯罪心理测试技术虽然由于其心理学原理的科学性而受到争议,并且对于测试人员的经验性要求较高,但是只要严格按照标准进行测试,其准确性仍然能够得到保障。 相似文献

Citizens participate in elections, at least partly, because they perceive voting as a social norm. Norms induce compliance because individuals prefer to avoid enforcement mechanisms—including social sanctions—that can be activated by uncooperative behavior. Public visibility, or surveillance, increases the likelihood of norm-compliant behavior and applies social pressure that impels individuals to act. Some scholars have linked social pressure to community size, advancing the notion that pressure to conform to social norms is heightened in smaller, less populous communities in which citizens interact frequently and where monitoring behavior is less onerous. Others argue that even highly-populated communities can exhibit “small world” properties that cause residents to be sensitive to social pressure. In this paper, I analyze data from a recent field experiment designed to test the impact of social pressure on voting taking interactions with community size into account. The findings I report suggest community size does not moderate the impact of social pressure. 相似文献

Research has shown that messages of intra-party harmony tend to be ignored by the news media, while internal disputes, especially
within the governing party, generally receive prominent coverage. We examine how messages of party conflict and cooperation
affect public opinion regarding national security, as well as whether and how the reputations of media outlets matter. We
develop a typology of partisan messages in the news, determining their likely effects based on the characteristics of the
speaker, listener, news outlet, and message content. We hypothesize that criticism of a Republican president by his fellow
partisan elites should be exceptionally damaging (especially on a conservative media outlet), while opposition party praise
of the president should be the most helpful (especially on a liberal outlet). We test our hypotheses through an experiment
and a national survey on attitudes regarding the Iraq War. The results show that credible communication (i.e., “costly” rhetoric
harmful to a party) is more influential than “cheap talk” in moving public opinion. Ironically, news media outlets perceived
as ideologically hostile can actually enhance the credibility of certain messages relative to “friendly” news sources.

The Ur-History of Media Space: Walter Benjamin and the Information Industry in Nineteenth-Century Paris 总被引:1,自引:1,他引:0
Jaeho Kang 《International Journal of Politics, Culture, and Society》2009,22(2):231-248
This essay is primarily concerned with Walter Benjamin’s analysis of the newspaper as a media space with reference to privatization
of urban space, industrialization of public communication, and mediazation of public space in nineteenth-century Paris. I
seek to show how the information industry brought about the fundamental changes in literary practice, intellectual activity,
and the formation of a new social subject. I also demonstrate how Benjamin’s rich illustration of the complex dynamics of
media space in the nineteenth century largely avoids the shortcomings of oversimplification embedded in the analysis of the
bourgeois public sphere. In doing so, I argue Benjamin’s critical analysis that the newspaper provides a systematic framework
by which to examine the intersection between the media space and the urban experience in a digital age.

ABSTRACTThe economic rationale for contracting out local services is increasingly contested by empirical research. This article aims to contribute to this literature, first by scrutinising the economic effects of contracting out in local road and park services and, second, by exploring how characteristics such as markets, contracts, municipal strategies and contracting history influence these outcomes. Drawing on original survey data from Danish municipalities, we find that competitive tendering has on average reduced costs. Further analysis shows that savings are not associated with lower quality, thus indicating that ‘quality shading’ was not taking place. Another finding is that municipalities that repeatedly contract the services experience smaller savings, suggesting that competitive tendering is subject to declining marginal returns. Finally, we find that larger municipalities and those emphasising expenditure cuts realise larger savings, whereas the characteristics of markets and contracts do not seem to explain variations in cost savings. 相似文献

In contemporary high-choice media environments, people increasingly mix and combine their use of various news media into personal news repertoires. Despite this, there is still limited research on how people compose their individual news repertoires and the effects of these news repertoires. To address this and further our understanding of how media use influences political participation, this study investigates (a) how people combine the use of offline and online media into personal news repertoires and (b) the effects of different news repertoires on both offline and online political participation. Based on a two-wave panel study covering the 2014 Swedish national election, this study identifies five news repertoires, labeled minimalists, public news consumers, local news consumers, social media news consumers, and popular online news consumers. Among other things, the results show that social media news consumers are more likely to participate in politics both offline and online. 相似文献

As evidence of the contextual effects of place upon individual outcomes has become increasingly solid over time, so too have urban policies and programs designed to connect underserved people with access to spatial opportunity. To this end, many attempts have been made to quantify the geography of opportunity and quite literally plot it on a map by combining evidence from studies on neighborhood effects with spatial data resources and geographic information systems (GIS) technology. Recently, these opportunity maps have not only become increasingly common but their preparation has been encouraged and facilitated by the U.S. Department of Housing and Urban Development. A closer look at the foundations and methods that underlie these exercises offers important lessons I examine the practice of opportunity mapping from both theoretical and methodological perspectives, highlighting several weaknesses of the common methods. Following this, I outline a theoretical framework based on Galster’s categorization of the mechanisms of neighborhood effects. Using data from the Baltimore metropolitan region, I use confirmatory factor analysis to specify a measurement model that verifies the validity of the proposed theoretical framework. The model provides estimates of four latent variables conceived as the essential dimensions of spatial opportunity: social-interactive, environmental, geographic, and institutional. Finally, I develop a neighborhood typology using unsupervised machine learning applied to the four dimensions of opportunity. Results suggest that opportunity mapping can be improved substantially through a better connection to the empirical literature on neighborhood effects, a multivariate statistical framework, and more direct relevance to public policy interventions. 相似文献
