This essay seeks to specify some of the social–psychological determinants that led to the mobilization of deadly state crime
in the Latin American authoritarian state context. The Mexican case provides an interesting case in which to specify some
of these determinants because hundreds of leftist political party militants, often engaged in legal activities, have been
gunned down by state agents (the police, the military, local politicians associated with the dominant party-state) or indirectly
by hired guns on behalf of state leaders Schatz. S. (Research in Social Movements, Conflicts and Change, 23:255–295, 2001). I argue, in the Mexican case, the leadership authorization of destructive behavior was the critical activating
historical condition activating deadly state crime because it created a permissive social milieu that allows for the utilization
of more extreme forms of violence including the use of political assassination as a mode of social control. This permissive
social milieu was, of course, aided by a passive legal system that generated the almost complete lack of penalties for state-sanctioned
brutality. While none of these determinants alone may be sufficient to produce a wave of political–electoral homicides, when
they all combine, it makes such destructive behavior very likely to occur. 相似文献

Associations between bullying behavior and school-related stress experience, self-efficacy, social support, and decision control were explored in a study of 885 Norwegian adolescents aged 13–15 years. Information was based on self-reports. The psychosocial factors were represented by an average of scores on 3–12 single items, each with 5 possible response categories. Bullying behavior was defined as bullying other pupils sometimes or more often during the term. The prevalence of bullying behavior was 9.2%, but significantly higher among boys than girls. Odds ratios of bullying behavior according to psychosocial factors were calculated in a multiple logistic regression analysis. Increasing school alienation was associated with an increased risk of bullying, whereas increasing support from teachers and peers decreased the risk. Increasing self-efficacy was associated with a significant increase in risk only among 14-year-old pupils, but a similar tendency was seen for 15-year-old pupils. No significant association was seen with decision control. 相似文献

The aim of this study was to investigate whether clinical reference premortem values can be used to assess postmortem concentrations of thyroxine, triiodothyronine, and thyroid stimulating hormone (TSH), to compare the postmortem concentrations in blood and vitreous humor, and to study the possibility of diagnosing hyperthyroidism by comparing thyroid histologic appearance and postmortem hormone values. Biochemical analyses of free thyroxine (FT4), free triiodothyronine (FT3), and TSH in femoral blood and vitreous humor were made in 38 cases. In 40 cases, the hormones and thyroid histologic appearance were studied; 22 had no significant pathologic changes, and 18 showed focal hyperplasia of the follicular epithelium. A positive correlation was seen between the femoral blood and vitreous humor concentrations of FT4 (R = 0.66) but not between the corresponding concentrations of FT3 and TSH. A positive correlation was also seen between FT3 and FT4 in femoral blood (R = 0.74). In cases with normal thyroid histologic appearance, 58% were found to have FT4 values >24 pmol/L (clinical reference interval 9-24 pmol/L), mean value 27.5 +/- 9.4 pmol/L), which did not differ from the FT4 values in the cases with hyperplasia, 31.6 +/- 15 pmol/L. Only 5% of the T3 measurements in the group with normal histologic appearance were >9 pmol/L (clinical reference interval 3-9 pmol/L). The mean value of FT3 in cases with normal histologic appearance was 3.4 +/- 1.3 pmol/L, and in the group with hyperplasia 8.6 +/- 6.1 pmol/L. The difference was statistically significant P < .005). It is concluded that postmortem values of FT3 and FT4 in femoral blood are fairly comparable to premortem clinical reference values, but the upper normal limit, especially for T4, has to be adjusted upward. Analysis of vitreous humor cannot be used post mortem to assess thyroid function. Histologically, hyperplastic changes correlate well with elevated FT3 in femoral blood. 相似文献

The ‘events approach’ claims for a new explanation of cabinet termination and cabinet survival in parliamentary democracies. The failure of the universal laws set by the culturalist approach and the party system approach raised the question whether one should search for random or probabilistic events of cabinet termination and survival. It is argued that the events approach fails both for the epistemological weakness of its premises and for the poverty of its empirical conclusions. A reappraisal of theoretical enterprise is advanced and a new research perspective is sketched, which requires a more careful treatment of the non‐uniform institutional features of parliamentary democracies. 相似文献
