Sociometric nominations, social cognitive maps, and self-report questionnaires were completed in consecutive years by 327
students (56% girls) followed longitudinally from grade 7 to grade 8 to examine the stability of social standing in peer groups
and correlates of changes in social standing. Social preference, perceived popularity, network centrality, and leadership
were moderately stable from grade 7 to grade 8. Alcohol use and relational aggression in grade 7 predicted changes in social
preference and centrality, respectively, between grade 7 and grade 8, but these effects were moderated by gender and ethnicity.
Changes in social standing from grade 7 to grade 8 were unrelated to grade 8 physical aggression, relational aggression, and
alcohol use after controlling for the grade 7 corollaries of these behaviors. Results are discussed in terms of their implications
for understanding links between social standing and problem behaviors during adolescence.

Structured analytic techniques (SATs) are intended to improve intelligence analysis by checking the two canonical sources of error: systematic biases and random noise. Although both goals are achievable, no one knows how close the current generation of SATs comes to achieving either of them. We identify two root problems: (1) SATs treat bipolar biases as unipolar. As a result, we lack metrics for gauging possible over-shooting—and have no way of knowing when SATs that focus on suppressing one bias (e.g., over-confidence) are triggering the opposing bias (e.g., under-confidence); (2) SATs tacitly assume that problem decomposition (e.g., breaking reasoning into rows and columns of matrices corresponding to hypotheses and evidence) is a sound means of reducing noise in assessments. But no one has ever actually tested whether decomposition is adding or subtracting noise from the analytic process—and there are good reasons for suspecting that decomposition will, on balance, degrade the reliability of analytic judgment. The central shortcoming is that SATs have not been subject to sustained scientific of the sort that could reveal when they are helping or harming the cause of delivering accurate assessments of the world to the policy community. 相似文献

Research on negative campaigning has largely overlooked the role of stereotypes. In this study, we argue that the gender and partisan stereotypes associated with traits and policy issues interact with a candidate’s gender and partisanship to shape the effectiveness of campaign attacks. We draw on expectancy-violation theory to argue that candidates may be evaluated more harshly when attacks suggest the candidate has violated stereotypic assumptions about their group. Thus, attacks on a candidate’s “home turf,” or those traits or issues traditionally associated with their party or gender, may be more effective in reducing support for the attacked candidate. We use two survey experiments to examine the effects of stereotype-based attacks—a Trait Attack Study and an Issue Attack Study. The results suggest that female candidates are particularly vulnerable to trait based attacks that challenge stereotypically feminine strengths. Both male and female candidates proved vulnerable to attacks on policy issues stereotypically associated with their party and gender, but the negative effects of all forms of stereotype-based attacks were especially large for democratic women. Our results offer new insights into the use of stereotypes in negative campaigning and their consequences for the electoral fortunes of political candidates. 相似文献

Most colleges and universities in the United States face serious questions about missions, money, and morale in the 21st century. Some recent excellent books are useful for showing divergent perspectives on these problems. To one extreme, an historian tends to see that lack of planning has been an unexpected, enduring positive force. To another extreme, a high profile state university president draws on innovations in structure to deal with changes in demographics and academic fields. This review essay provides a balanced exploration of the disparate approaches, leading to the conclusion that American higher education is in need of a substantive "New Deal" in purposes and policies. 相似文献

This articles uses the work of Pyrooz and Densley as a springboard for a larger discussion of race-based perceptions from gangs to criminals to athletes. It concludes by showcasing how perceptions do not always equate with reality and the consequences of doing so. 相似文献

In this Special Section, this article reviews South Korean views on Japan's ‘peace’ Constitution and the Abe government's attempts at constitutional reform. It identifies three different understandings among South Korean academics on why Japan is escalating attempts to revise the Constitution under the Abe government. An in-depth analysis demonstrates that all three perspectives pay specific attention to Japan's constitutional reform in relation to security policy changes. However, they differ in assessing the impact of Japan's constitutional reform on South Korea as well as how South Korea should deal with such a change. A minority opinion considers Japan's ‘remilitarisation’ through constitutional revision as conducive to South Korean security interests by increasing deterrence against North Korea, whereas the dominant opinion is that any attempt to revise the Constitution could be in and of itself a potential threat to South Korea's security due to a lack of trust attributed to unresolved historical conflicts between Korea and Japan. However, all three approaches pay hardly any attention to the positive role of Japan's peace Constitution while Japan's peace Constitution might provide a regional peace model in Northeast Asia. 相似文献
