In a simulated crime stituation, 3 groups of eyewitnesses viewed 2 target persons through a one-way mirror and were tested for accuracy of identification after dealy periods of 2, 21, or 56 days. Subjects made identifications from either a live “show-up” or by looking at photographs. In both methods of testing only 1 of the 2 targets was actually present in the 5-man array. Results indicated that delay affects number of false alarms, test method affects number of hits. Photographs produced less accurate performance than live show-up. More than 60% of the subjects erroneously selected one of the 4 distractor persons, a finding relevant to the use of eyewitness identification in criminal investigations. Only 28% of the subjects made no errors of identification. 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
Substantial research has been conducted towards understanding why and how universities shape regional wealth and competitiveness. In this paper we extend this literature to examine empirically causal relationships between university-induced knowledge spillovers and regional wealth using a hand collected panel data set from 1998 to 2012. Literature has identified three possible effects of causality, namely that a university exogenously fosters and spurs regional wealth, second that universities are endogenously shaped by regional wealth and finally that regional wealth and universities follow an interlinked and co-evolutionary path. Our findings support the latter direction in that universities and their regional endowment are linked together. 相似文献
Both lay persons and professionals believe that the emotions displayed by a child witness during disclosure of sexual abuse are a factor of importance when judging the child's credibility. Unfortunately, not all children display emotions according to expectations, leading to misjudgments, and possible miscarriage of justice. In the present study, we examined how lay people's credibility judgments were influenced by a child's displayed emotions during the disclosure of sexual abuse. Participants (n?=?119), viewed video recordings of a mock police interview of an 11-year-old child actor disclosing sexual abuse, displaying one of four emotional expressions (angry, sad, neutral, and positive). Results showed that participants were strongly influenced by the emotions displayed; in particular, the display of strong negative emotions (anger) or positive emotions during disclosure significantly reduced judged credibility. The credibility ratings predicted the participant? judgments of the defendant's guilt and the willingness to pass a guilty vote in a hypothetical trial. 相似文献
There is an emerging intellectual body of thought on the dynamics of de-politicisation and the “disappearance of the political”. In the first part of the paper, I shall consider the process of post-politicisation. In a second part, I shall re-centre the political by drawing on the work of a range of political theorists and philosophers who have begun to question this post-politicising process. The theme of the final section will consider the contours of a reawakening of the democratic political understood as a political order contingently based on the axiomatic presumption of equality of each and every one in their capacity to act politically. 相似文献
This study examines the conditions that make adolescents open to their parents’ attempts at political socialization. Based on a reformulation of the perceptual accuracy argument, that parents’ messages are filtered through correct perceptions of these messages by adolescents, the study suggests that adolescents who accurately recognize their parents’ high political sophistication are particularly likely to attend to and be open to their parents’ political communication. This proposition was tested using cluster analysis of a sample of 505 Swedish upper-secondary students and their parents (51% girls; Mage?=?16.56, SD?=?0.67). The analysis yielded two clusters where adolescents correctly identified (26%) and failed to correctly identify (22%) their parents’ high political sophistication, and three clusters where both parents and adolescents reported low or medium parental political sophistication (10%, 11%, and 32%). In confirmation of the hypothesis, members of the cluster group of adolescents who correctly recognized their parents’ high political sophistication were particularly aware of parents’ political socialization attempts and receptive to parents’ political communication. Moreover, these youth considered their parents’ political views as important and, accordingly, seemed to perceive their parents as political role models.
The abilities of national administrative agencies in Sweden and the United States to function effectively are influenced by their responses to three major phenomena: 1) growth in the responsibilities of government; 2) decentralization; and, 3) privatization. This paper delineates how these phenomena have affected the development of national administrative organizations in these two countries. Implications for administering national agencies in increasingly complex interorganizational environments are discussed. 相似文献
It is widely believed that cyberspace is offense dominant because of technical characteristics that undermine deterrence and defense. This argument mistakes the ease of deception on the Internet for a categorical ease of attack. As intelligence agencies have long known, deception is a double-edged sword. Covert attackers must exercise restraint against complex targets in order to avoid compromises resulting in mission failure or retaliation. More importantly, defenders can also employ deceptive concealment and ruses to confuse or ensnare aggressors. Indeed, deception can reinvigorate traditional strategies of deterrence and defense against cyber threats, as computer security practitioners have already discovered. The strategy of deception has other important implications: as deterrence became foundational in the nuclear era, deception should rise in prominence in a world that increasingly depends on technology to mediate interaction. 相似文献
