Being a victim of sexual aggression from a peer is a common experience among adolescents and poses a significant risk for various forms of psychopathology. Unfortunately, little is known concerning specific interpersonal factors that increase an adolescent’s risk for experiencing sexual aggression. The current study assessed the contribution made by several interpersonal factors both for the first and repeated experience of becoming a victim of sexual aggression from a peer. Data were collected annually from a longitudinal sample of 200 adolescents over a period of 4 years and were analyzed using multiple-spell, discrete-time survival analysis. Approximately 46% of the adolescents reported experiencing some form of sexual aggression by the end of wave 4. Further, 65% of victims reported experiencing a repeat incident of aggression. Females were at higher risk both for initial and repeated victimization, as were adolescents with more sexual experience and higher levels of rejection sensitivity. Results are discussed in terms of implications for future prevention efforts.

We review the theoretical literature on the concept of institutions and its relationship to national development, propose a definition of the concept, and advance six hypotheses about institutional adequacy and contributions to national development. We then present results of a comparative empirical study of existing institutions in three Latin American countries and examine their organizational similarities and differences. Employing the qualitative comparative method (QCA) proposed by Ragin, we then test the six hypotheses. Results converge in showing the importance of meritocracy, immunity to corruption, absence of “islands of power,” and proactivity in producing effective institutions. Findings strongly support Peter Evans’ theory of developmental apparatuses.

In this article, we test individual and contextual level hypotheses about right-wing extremist voting in Germany derived from cleavage theory and the theory of realistic group conflicts. The data base is exceptional insofar as it allows multilevel analyses of right-wing extremism that include the level of the German districts between the respondent and the federal state level. Our findings demonstrate — to our knowledge for the first time — that the contextual influence of the religious/catholic milieu as well as of the regional tradition of trade union membership reduce the likelihood of a right-wing extremist party preference. Cleavage theory is thus clearly supported. With respect to the theory of realistic group conflicts we find support for some of its implications.  相似文献

Do state supreme courts act impartially or are they swayed by public opinion? Do judicial elections influence judge behavior? To date these questions have received little direct attention due to the absence of comparable public opinion data in states and obstacles to collecting data necessary for comprehensive analysis of state supreme court outcomes. Advances in measurement, data archiving, and methodology now allow for consideration of the link between public opinion and judicial outcomes in the American states. The analysis presented considers public opinion's influence on the composition of courts (indirect effects) and its influence on judge votes in capital punishment cases (direct effects). In elective state supreme courts, public support for capital punishment influences the ideological composition of those courts and judge willingness to uphold death sentences. Notably, public support for capital punishment has no measurable effect on nonelective state supreme courts. On the highly salient issue of the death penalty, mass opinion and the institution of electing judges systematically influence court composition and judge behavior.  相似文献

One of the key recommendations of the Winter Commission was the empowerment of governors over the executive branch. However, key institutions have not evolved in this direction; the long ballot still exists in most states, and the formal powers of governors have strengthened to their probable capacity. The authors suggest that a quasi‐formal power—the gubernatorial use of executive orders—may be a significant tool for empowering the governor in the state administrative realm. Analyzing all executive orders in 49 states for 2004 and 2005, they find variation in the aggregate use of and functions performed through these orders. Many executive orders do allow the government more direction and control of state bureaucracy. Finally, the authors suggest that the study of executive orders may be necessary to understand gubernatorial power in the executive arena and beyond.  相似文献
