Over the past two decades, South Africa has sought to perform several roles on the world stage, such as the economic dynamo of Southern Africa, a diplomatic heavyweight representing the African continent, and a norm leader on the world stage as a so-called ‘middle-power’. Although South Africa's evolution and rise as an important player in global affairs has generated a welcome body of critical scholarly literature, comparatively little analysis has been allocated to understanding how norm dynamics and the country's ever-evolving international identities have enabled it to construct and reconstruct its ‘interests’. Social constructivism is best suited for such an analysis because it can operationalise norms, commitments, identities, and interests, and it provides the epistemological tools to map the increasingly multilateral connections between global, regional, and domestic forums. By employing a rationalist approach to constructivism, this paper remedies the aforementioned gap in the literature by illustrating how South Africa constructs and reconstructs its identities and interests in relation to membership in international organisations (IOs). To that end, the paper examines the evolution of South Africa's participation in the African Union (especially ‘peacekeeping’ contributions) and the International Criminal Court. The paper concludes by assessing the theoretical implications and practical ramifications of the norm dynamics involved in South Africa's commitment to these two IOs. 相似文献

In prior tests of Beckerian rational choice theory, the notion that individuals are responsive to the (dis)incentives associated with crime has been supported. Much of this research has comprised composite scores of perceived rewards and risks of multiple, often disparate, crime types that are then used to predict “general” offending behavior. Although the results of such prior tests are informative, we believe that this tendency has resulted in two shortcomings. First, a central component of mathematical rational choice theory is overlooked, namely, that responsivity to incentives will be crime specific. That is, offenders should prefer crime types that subjectively offer greater rewards and fewer risks relative to other crimes. Second, individual differences in offending specialization are not addressed, of which Clarke and Cornish (1985) and Shover (1996) argued rational choice theories are well suited to explain. Using a sample of serious offenders, we find that in a given time period, individuals are more likely to engage in crime types they viewed as more intrinsically rewarding and less risky compared with other crimes. Furthermore, individuals displayed greater specialization in violence to the extent they view violence as more rewarding and less risky than property offenses 相似文献

Peer victimization is a significant risk factor for a range of negative outcomes during adolescence, including depression and anxiety. Recent research has evaluated individual characteristics that heighten the risk of experiencing peer victimization. However, the role of emotional clarity, or the ability to understand one’s emotions, in being the target of peer victimization remains unclear. Thus, the present study evaluated whether deficits in emotional clarity increased the risk of experiencing peer victimization, particularly among adolescent girls, which, in turn, contributed to prospective levels of depressive and anxiety symptoms. In the present study, 355 early adolescents (ages 12–13; 53 % female; 51 % African American) who were part of the Adolescent Cognition and Emotion project completed measures of emotional clarity, depressive symptoms, and anxiety symptoms at baseline, and measures of peer victimization, depressive symptoms, and anxiety symptoms at follow-up. Moderation analyses indicated that deficits in emotional clarity predicted greater peer victimization among adolescent girls, but not adolescent boys. Moderated mediation analyses revealed that deficits in emotional clarity contributed to relational peer victimization, which, in turn, predicted prospective levels of depressive and anxiety symptoms among adolescent girls, but not boys. These findings indicate that deficits in emotional clarity represent a significant risk factor for adolescent girls to experience relational peer victimization, which, in turn, contributed to prospective levels of internalizing symptoms. Thus, prevention programs should target deficits in emotional clarity to prevent peer victimization and subsequent internalizing symptoms among adolescent girls. 相似文献

Estimating postmortem interval (PMI) of surface found skeletal remains is challenging. This novel study used UV‐Vis‐NIR spectroscopy to scan soil collected from cadaver decomposition islands (CDIs) ranging from 15‐ to 963‐d postmortem and control soils. A decomposition product spectra model (DPS model) was constructed by deducting the control soil spectra from the CDI soil spectra for the estimation of postmortem indices: PMI (d), ADD4, ADD10, and ADD20. The DPS model (n = 55) was calibrated and subjected to a full cross‐validation. Calibration R2 and RPD for the DPS model ranged from 0.97 to 0.99 and from 6.1 to 9.9, respectively, for the four postmortem interval indices. Validation R2 and RPD for the DPS model ranged from 0.73 to 0.80 and from 1.9 to 2.2, respectively. The DPS model estimated postmortem intervals for three test CDIs in a clay soil under perennial grassland (test set 1; n = 3) and six CDIs in a sandy soil under a loblolly pine forest (test set 2; n = 6). Test set 1 had PMI prediction ranges from ?69 to ?117 days, ?796 to +832 ADD4, +552 to +2672 ADD10, and ?478 to ?20 ADD20 of observed PMI. Test set 2 PMI prediction ranged from ?198 to ?65 days, ?9923 to +2629 ADD4, ?6724 to +1321 ADD10, and ?2850 to +540 ADD20 of observed PMI. Test set 2 had poor predictions for two CDIs, for all measures of postmortem indices resulting in discussion of sampling depth, effect of body mass index (BMI), and scavenging. 相似文献
