The present study explored the heterogeneous nature of popularity by investigating subgroups of popular girls (N = 365) in their first year of secondary school (mean age  =  13.05). Cluster analysis revealed the presence of five subgroups based upon sociometric popularity (i.e., those considered likeable by peers) and consensual popularity (i.e., those considered popular by peers), and academic behavioral indices. Two of these groups contained girls who were all nominated as “popular” by classmates, yet the girls in one group displayed very positive academic behaviors (Popular Studious); girls in the other popular group displayed extreme antiacademic behaviors (Popular Disengaged). The remaining groups were Average Popular, Unpopular Disengaged, and Unpopular Studious. External validating measures confirmed the existence of the subgroups, that is, Popular Studious girls were judged by classmates to behave in a prosocial fashion, whereas Popular Disengaged girls exhibited many antisocial behaviors, and were often nominated as bullies. Unpopular Studious girls were often nominated as victims. These findings confirmed the hypothesis that consensual popularity is a heterogeneous concept, and that antiacademic and antisocial girls may still be among the most consensually popular students in secondary schools.Lecturer at the Department of Educational Sciences, University of Amsterdam, Wibautstraat 4, 1091 GM Amsterdam, The Netherlands.

This article examines four accepted wisdoms about HIV/AIDS andAfrican armies and in each case concludes that substantial revisionis necessary in the light of emerging evidence. First, it appearsthat military populations do not necessarily have a higher prevalenceof HIV than civilian populations. HIV levels in armies dependon many factors including the demographics of the army, itspattern of deployment, the nature and stage of the epidemicin the country concerned, and the measures taken to controlthe disease by the military authorities. Second, although theepidemic has the potential to undermine the functioning of nationalmilitaries, and may have done so in isolated instances, armiesin general are well placed to withstand the threat. Third, evidencethat war contributes to the spread of the virus is meagre andsuggests that we should be concerned primarily with specificrisks that conflict may entail including population mobilityand changing sexual networks. Lastly, the hypothesis that AIDShas the potential to disrupt national, regional, and internationalsecurity remains speculative. 1.

“行为”是犯罪最基本的分析单位和最基本的特征要素,是刑法学研究的逻辑起点。对贩卖假毒品行为的定性及处罚不仅仅是司法实践中的难题,而且涉及到许多刑法理论问题,诸如不能犯与未遂犯的区别,行为无价值论与结果无价值论的争议等。本文主张以结果无价值为基本根据评价行为的实质违法性,如果行为人不知是假毒品而以毒品进行贩卖的,不应以贩卖毒品罪追究其刑事责任。  相似文献

Political scientists often argue that political processes movetogether in the long run. Examples include partisanship andgovernment approval, conflict and cooperation among countries,public policy sentiment and policy activity, economic evaluationsand economic conditions, and taxing and spending. Error correctionmodels and cointegrating relationships are often used to characterizethese equilibrium relationships and to test hypotheses aboutpolitical change. Typically the techniques used to estimateequilibrium relationships are based on the statistical assumptionthat the processes have permanent memory, implying that politicalexperiences cumulate. Yet many analysts have argued that thisis not a reasonable theoretical or statistical assumption formost political time series. In this paper I examine the consequencesof assuming permanent memory when data have long but not permanentmemory. I focus on two commonly used estimators: the Engle-Grangertwo-step estimator and generalized error correction. In my analysisI consider the important role of simultaneity and discuss implicationsfor the conclusions political scientists have drawn about thenature, even the existence, of equilibrium relationships betweenpolitical processes. I find that even small violations of thepermanent memory assumption can present substantial problemsfor inference on long-run relationships in situations that arelikely to be common in applied work in all fields and suggestways that analysts should proceed.  相似文献

The premise of political priming is that public evaluations of political leaders are made on the basis of issues that are on the top of citizens' minds. This study investigated the impact of a national referendum campaign about a European integration issue on the evaluation of the incumbent government, the prime minister, and the opposition leaders. Drawing on a content analysis of news media and a two-wave panel survey, the results showed that as the topic of the referendum (the introduction of the euro) became more visible in the media during the campaign the importance of the euro issue for formulating general evaluations of political leaders increased. The incumbent government that was seen to handle the referendum poorly was penalized by the referendum. Exposure to news media outlets that covered the referendum extensively and offered negative evaluations of political leaders boosted the decline in the overall performance rating of political leaders by politically less involved respondents. These results stress the necessity of considering the campaign and the specific content of the media to understand fluctuations in public opinion during a referendum campaign. The study concludes with a discussion of the implications of a referendum campaign for political leaders.  相似文献

The emergence and future of PPOs   总被引:2,自引:0,他引:2  
A new development in the restructuring of American health care is the dramatic growth of preferred provider organizations (PPOs). Based on a national telephone survey, this paper assesses the future direction of PPOs by examining segments of the market that are believed to be lead indicators of future activity. It includes analyses of "new" versus "old" PPOs, the ten largest PPOs, and the entrance of hospital chains into the insurance market. We conclude that the dramatic growth of PPO enrollment in 1985 is likely to continue in the future, but with increased movement toward vertical integration and joint ventures among providers and insurers.  相似文献

Problems related to blood contamination by other postmortem fluids in decomposed bodies (DB) make the interpretation of medicolegal blood alcohol levels (B EtOH) a very difficult task. So the aim of this paper is to show the utilization of vitreous humor (VH) as the biological fluid for an unequivocal determination of ethanol origin in DB for forensic purposes. Alcohol was determined in VH, blood (chest fluid-CF) and urine (Ur) collected from 27 DB in different states of putrefaction. A simple head-space gas-chromatographic method was used. In fifteen cases alcohol was found to be of endogenous production due to its absence in VH. In the twelve remainders, alcohol was detected in VH and CF in an atypical distribution. Examining the reliable scene and historical information together with the analytical data, ethanol origin in these cases was classified: endogenous production (3 cases), ingested (2 cases), both (2 cases), contaminated plus endogenous production (3 cases) and unable to determine (2 cases). According to the results obtained it was possible to conclude that alcohol analysis in VH is fundamental for determining the origin of ethanol detected in CF of DB.  相似文献
