Why do some leaders make deeper commitments to human rights treaties (HRAs) by consenting to receive extra monitoring of complaints or communications from individual citizens? Extant theory suggests leaders join HRAs for tangible benefits. However, empirical support for this argument is mixed. To address this mismatch, we approach this question from a different angle. We argue that by ratifying HRAs, leaders send a signal that they are reliable partners who value future returns. Accepting optional articles and protocols that increase monitoring of the state’s human rights behavior, without changing the state’s substantive obligations, helps better signal that the regime does not fear instability nor sees the need to resort to the proscribed abuses in the future. This, in turn, serves as an important middle step to recognizing tangible benefits, such as foreign direct investment, by improving investors’ risk perception of ratified countries.  相似文献

An accruing body of evidence supports associations between self-perceived gender typicality and peer relationship difficulties; however, researchers have yet to evaluate peers' perceptions of problem behaviors to gain insight into the social correlates of gender typicality. A short-term longitudinal study was conducted to evaluate associations between gender atypical problem behavior and subsequent peer relational difficulties for 2,076 fifth graders (M age= 10.27; 53% female). Peer nomination methodology was used to assess participants' classroom peer relationships, problem behaviors, and social-emotional characteristics. Findings showed that youth characterized by gender atypical, compared to gender typical, problem behavior (withdrawn boys/aggressive girls vs. withdrawn girls/aggressive boys, respectively) evidenced higher levels of subsequent peer difficulties; moreover, participation in a mutual friendship was associated with decreased risk for peer relationship maladjustment, particularly among youth characterized by gender atypical problem behavior. Results further revealed that, compared to friendless youth, friended youth earned higher prosocial and peer liking scores and, for withdrawn youth, lower emotional sensitivity scores. The present research contributes to our understanding of the potential short-term consequences of youth's gender atypical problem behavior. Findings underscore the need for supplemental conceptualizations of gender typicality as well as multifaceted interventions designed to promote the acceptance of gender nonnormativity, support the development of adaptive peer relationships, and reduce the occurrence of problem behaviors.  相似文献

Age is one of the most robust correlates of criminal behavior. Yet, explanations for this relationship are varied and conflicting. Developmental theories point to a multitude of sociological, psychological, and biological changes that occur during adolescence and adulthood. One prominent criminological perspective outlined by Gottfredson and Hirschi claims that age has a direct effect on crime, inexplicable from sociological and psychological variables. Despite the attention this claim has received, few direct empirical tests of it have been conducted. We use data from Pathways to Desistance, a longitudinal study of over 1,300 serious youthful offenders (85.8 % male, 40.1 % African-American, 34.3 % Hispanic, 21.0 % White), to test this claim. On average, youths were 16.5 years old at the initial interview and were followed for 7 years. We use multilevel longitudinal models to assess the extent to which the direct effects of age are reduced to statistical and substantive non-significance when constructs from a wide range of developmental and criminological theories are controlled. Unlike previous studies, we are able to control for changes across numerous realms emphasized within differing theoretical perspectives including social control (e.g., employment and marriage), procedural justice (e.g., perceptions of the legitimacy and fairness of the legal system), learning (e.g., gang membership and exposure to antisocial peers), strain (e.g., victimization and relationship breakup), psychosocial maturity (e.g., impulse control, self-regulation and moral disengagement), and rational choice (e.g., costs and rewards of crime). Assessed separately, these perspectives explain anywhere from 3 % (procedural justice) to 49 % (social learning) of the age-crime relationship. Together, changes in these constructs explain 69 % of the drop in crime from ages 15 to 25. We conclude that the relationship between age and crime in adolescence and early adulthood is largely explainable, though not entirely, attributable to multiple co-occurring developmental changes.  相似文献

The following article traces the development of East Germany's secret police, the Stasi, during the reign of Ernst Wollweber, the second Minister of State Security. By examining key Stasi operations during this period, notably the ‘concentrated strikes’ strategy following the June 1953 revolution, the campaign against Ostbüros, and operations to secure the economy, and by examining Wollweber's major speeches, it argues that Wollweber's reign was a decisive one for the Stasi because of the integration of intelligence gathering outside of East Germany (Aufklärung) with domestic surveillance (Abwehr). Although this balance shifted toward external duties in Wollweber's landmark August 1955 speech, Wollweber continued to promote integration of the two duties, in particular by anchoring the intelligence gathering duties in the local-level domestic structures of the Stasi.  相似文献

The widespread use over the past two decades of Michigan's PA 198 Industrial Tax Abatement program provides an opportunity to assess the inter‐urban equity impacts of this economic development tool. Not only has PA 198 been used relatively more often by suburban municipalities, local governments at the metropolitan periphery are more likely to use abatements to attract new plants and new jobs. The older central cities primarily use the program to retain existing jobs, albeit at high cost of lost tax revenues. On balance, it appears that PA 198 has done little to alter the location decisions of participating firms.  相似文献
