Attachment, affect, and sex shape responsivity to psychosocial stress. Concurrent social contexts influence cortisol secretion, a stress hormone and biological marker of hypothalamic–pituitary–adrenal axis activity. Patterns of attachment, emotion status, and sex were hypothesized to relate to bifurcated, that is, accentuated and attenuated, cortisol reactivity. The theoretical framework for this study posits that multiple individual differences mediate a cortisol stress response. The effects of two psychosocial stress interventions, a modified Trier Social Stress Test for Teens and the Frustration Social Stressor for Adolescents were developed and investigated with early adolescents. Both of these protocols induced a significant stress reaction and evoked predicted bifurcation in cortisol responses; an increase or decrease from baseline to reactivity. In Study I, 120 predominantly middle-class, Euro-Canadian early adolescents with a mean age of 13.43 years were studied. The girls’ attenuated cortisol reactivity to the public performance stressor related significantly to their self-reported lower maternal-attachment and higher trait-anger. In Study II, a community sample of 146 predominantly Euro-Canadian middle-class youth, with an average age of 14.5 years participated. Their self-reports of higher trait-anger and trait-anxiety, and lower parental attachment by both sexes related differentially to accentuated and attenuated cortisol reactivity to the frustration stressor. Thus, attachment, affect, sex, and the stressor contextual factors were associated with the adrenal-cortical responses of these adolescents through complex interactions. Further studies of individual differences in physiological responses to stress are called for in order to clarify the identities of concurrent protective and risk factors in the psychosocial stress and physiological stress responses of early adolescents. 相似文献

This research used open source information to investigate the motivational backgrounds of 219 suicide attackers from various regions of the world. We inquired as to whether the attackers exhibited evidence for significance quest as a motive for their actions, and whether the eradication of significance loss and/or the aspiration for significance gain systematically differed according to attackers’ demographics. It was found that the specific nature of the significance quest motive varied in accordance with attackers’ gender, age, and education. Whereas Arab-Palestinians, males, younger attackers, and more educated attackers seem to have been motivated primarily by the possibility of significance gain, women, older attackers, those with little education, and those hailing from other regions seem to have been motivated primarily by the eradication of significance loss. Analyses also suggested that the stronger an attacker’s significance quest motive, the greater the effectiveness of their attack, as measured by the number of casualties. Methodological limitations of the present study were discussed, and the possible directions for further research were indicated. 相似文献

This article identifies and estimates economic drought vulnerability indicators among communal farmers in South Africa, using an economic vulnerability index based on a household survey of 121 communal farmers. The results show that lack of resources, unemployment, price sensitivity, market access, the level of farm debt, output, on- and off-farm diversification, management, and financial safety nets were the main economic vulnerability variables. Farm debt and financial safety provide the bulk of the vulnerability index. The study’s findings suggest that government should reconsider priorities in the implementation of appropriate policy measures in response to drought. 相似文献

This paper explores how remittances influence happiness among migrants and their households of origin. It is based on a novel data set of matched samples of Bangladeshi migrant households (living in the UK and Malaysia) and their origin families in Bangladesh. Empirical findings suggest that remittances play a significant role in stimulating migrants’ happiness. We also find that the households of origin’s life satisfaction not only depends on receiving remittances from the emigrants, but also other factors such as number of migrants from the household living abroad and the migrants’ country of destination. 相似文献

Why are some Latin American states plagued by persistent policy volatility while the policies of others remain relatively stable? This article explores the political economy of natural resource rents and policy volatility across Latin America. It argues that, all else equal, resource rents will create incentives for political leaders, which will result in repeated episodes of policy volatility. This effect, however, will depend on the structure of political institutions. Where political institutions fail to provide a forum for intertemporal exchange among political actors, natural resource rents will result in increased levels of policy volatility. Alternatively, where political institutions facilitate agreement among actors, resource rents will be conducive to policy stability. This argument is tested on a measure of policy volatility for 18 Latin American economies between 1993 and 2008. The statistical tests provide support for the argument. 相似文献

This article addresses the question of whether the economic crisis provides a politically opportune time to drastically curtail public healthcare in South Europe or whether, instead, there are signs of longer-term reform strategies for potentially balancing fiscal targets with the quest for enhanced value and health outcomes, when eventually growth resumes. After a brief examination of the profile of healthcare systems in Greece, Italy, Portugal and Spain prior to the crisis, we comparatively assess the mix of retrenchment, restructuring and recalibration strategies. The effects of the austerity-driven reforms on current (and expected) health outcomes are also briefly analysed. We conclude with reflections on the future of public healthcare in South Europe. 相似文献
