The Crown Jewels, published in Great Britain in 1998 and the United States in 1999, is Oleg Tsarev's second book drawn from KGB archives and written in cooperation with a Western author in this case, Nigel West.1 This important, complex book has much to offer historians, especially those inclined toward archeology, for Tsarev has skillfully choreographed his version of history to dance around the facts of some very well known intelligence and espionage cases. Consequently, he deposits another dense layer of evidence to sift, sort, and evaluate. But an assessment of Tsarev's volume also leads to three major points. Admittedly, two are glimpses of the blindingly obvious,'' restated here because these fundamentals become buried under media hype. First, that new historical evidence requires careful interpretation. Second, the secrets spies gather should be evaluated within the context of national and institutional policy formulation and implementation. Third, the notion of damage'' from Soviet espionage, has been exaggerated and misunderstood, and it is now time to investigate the impact of Soviet espionage upon national and international politics. And, most relevantly, Tsarev, a former lieutenant colonel in the Russian Foreign Intelligence Service, also serves as a consultant to the Service's press department.  相似文献

Two ideas concerning the link between bullying in school and violence on the streets are investigated. (1) Bullying and victimization in school is a product of the school situation and people's inability to choose their levels of exposure to others. According to this hypothesis, bullying is largely a phenomenon that is isolated to the school context. (II) Bullying behaviour in school and inflicting damage to others outside school is a reflection of a more general aggressive behaviour pattern and, hence, bullying in school and violence on the streets will, to a great extent, involve the same individuals. The literature offers suggestions that either could be the case. Participants were 2915 14-year-olds in a medium-sized county in Sweden who responded to a self-report questionnaire.Theresults showed that bullying others in school was strongly linked to violent behaviour and weapon-carrying on the streets, both among boys and girls. It was also found that bullying others in school was related to being violently victimized on the streets. The findings remained the same when statistically controlling for loitering and nights spent away from home, which were both related to bullying behaviour. It is concluded that bullying behaviour in school is in many cases a part of a more general violent and aggressive behaviour pattern and that preventive efforts targeting individuals with bullying behaviour in school could, according to the present study, decrease violence among adolescents out in the community as well.  相似文献

Smokeless tobacco and areca nut are popular with South Asians and South Asian immigrants, most commonly used as paan and gutka. Their regular use leads to oral cancer. The South Asian community in the U.S. is rapidly growing, where paan and gutka are readily available. The study was the first exploration of the migration of the paan and gutka habits, and their use in the U.S.A 108-item questionnaire on paan and gutka usage and beliefs was administered to 138 first-generation Bangladeshi and Indian-Gujarati immigrant adults at community sites in the New York metropolitan area. Forty-five percent Indian-Gujaratis reported ever-regular paan use; of which 5% are current users. Thirty-one percent reported ever-regular gutka use; of which 77% are current users. Thirty-five percent Bangladeshis reported ever-regular paan use; of which 70% arc current users. Nine percent reported ever-regular gutka use; of which 67% are current users. Bangladeshis are more likely to identify paan as causing oral cancer. Indian-Gujaratis are more likely to identify gutka as causing oral cancer.Between the two communities, there were significant differences in paan and gutfca usage, migration effects, and oral career risk perception. There is a need for comprehensive migration studies on the determinants of usage, and for community-specific interventions for these carcinogenic products.  相似文献

Despite the important consequences of citizens' election quality perceptions on political behavior and political attitudes, very little is known about how citizens formulate their perceptions of election quality. In this paper, I assess the correlates of citizens' perceptions of election quality. I suggest that the performance of election-related institutions is an important correlate of citizens' election quality perceptions. However, citizens' experience with electoral irregularities, and partisan affiliation also matter. I test these hypotheses in the context of the 2007 Nigerian general elections using survey data from Afrobarometer and International Foundation for Electoral Systems. The findings provide robust support for the hypotheses. Most importantly, the results indicate that the performance of electoral management bodies is associated with citizens' assessment of election quality in Africa and that citizens demand electoral management bodies with impartiality and professionalism.  相似文献

Girls’ early pubertal timing has been linked in many studies to behavioral problems such as delinquency and substance use. The theoretical explanations for these links have often involved the girls’ peer relationships, but contexts have also been considered important in some explanations. By integrating two theoretical models, the peer-socialization and the contextual-amplification hypotheses, we propose a contextual framework for explaining the link between early pubertal timing and external problem behavior in girls. We hypothesize that early developing girls engage in unhealthy, dangerous, and risky behavior under contextual conditions that promote access to older friends and opposite-sex relationships. Under other conditions it is less likely. We tested this integrated hypothesis in two studies conducted in Sweden. The first was a cross-sectional study with information about school and free-time friends in a community sample (N = 284). Early pubertal timing was linked to having older, more normbreaking friends outside of school, but not in school, thus suggesting that the school context interferes early-developing girls’ selection of older peers. The second study involved both a longitudinal (N = 434) and a cross-sectional sample of girls (N = 634), where we examined a leisure setting that is known to attract delinquent youth. Results showed that early pubertal timing was most strongly linked to delinquency for girls who spent time in this context and were heavily involved with boys and peers. In sum, results from both studies supported our predictions that certain contexts would amplify the peer-socialization effect. Overall, we conclude that the integrated peer-socialization/contextual-amplification model satisfactorily explains the link between pubertal timing and external problem behavior.  相似文献
