Studies investigating the connection between environmental factors and migration are difficult to execute because they require the integration of microdata and spatial information. In this article, we introduce the novel, publically available data extraction system Terra Populus (TerraPop), which was designed to facilitate population–environment studies. We showcase the use of TerraPop by exploring variations in the climate–migration association in Burkina Faso and Senegal based on differences in the local food security context. Food security was approximated using anthropometric indicators of child stunting and wasting derived from Demographic and Health Surveys and linked to the TerraPop extract of climate and migration information. We find that an increase in heat waves was associated with a decrease in international migration from Burkina Faso, while excessive precipitation increased international moves from Senegal. Significant interactions reveal that the adverse effects of heat waves and droughts are strongly amplified in highly food insecure Senegalese departments.  相似文献

Gambling studies have described a “near-miss effect” wherein the experience of almost winning increases gambling persistence. The near-miss has been proposed to inflate the value of preceding actions through its perceptual similarity to wins. We demonstrate here, however, that it acts as a conditioned stimulus to positively or negatively influence valuation, dependent on reward expectation and cognitive engagement. When subjects are asked to choose between two simulated slot machines, near-misses increase valuation of machines with a low payout rate, whereas they decrease valuation of high payout machines. This contextual effect impairs decisions and persists regardless of manipulations to outcome feedback or financial incentive provided for good performance. It is consistent with proposals that near-misses cause frustration when wins are expected, and we propose that it increases choice stochasticity and overrides avoidance of low-valued options. Intriguingly, the near-miss effect disappears when subjects are required to explicitly value machines by placing bets, rather than choosing between them. We propose that this task increases cognitive engagement and recruits participation of brain regions involved in cognitive processing, causing inhibition of otherwise dominant systems of decision-making. Our results reveal that only implicit, rather than explicit strategies of decision-making are affected by near-misses, and that the brain can fluidly shift between these strategies according to task demands.  相似文献

This study evaluated the effectiveness of the 2nd and 3rd editions of the Children First parent education programs for parents experiencing divorce or separation. Participants were 678 parents experiencing separation or divorce in 2 Midwestern counties. Changes from pretest to posttest on participants’ knowledge, attitudes, and likelihood of adaptive coparenting were assessed. Both editions of the program had a significant positive effect on all 3 measures of adaptive coparenting. The effect sizes from pretest to posttest for the 2nd edition were small, whereas the effect sizes for the 3rd edition of the program were nearly twice as large. Superiority of the 3rd edition might be due to an increased focus on explicit training on adaptive coparenting behaviors.  相似文献

Drawing upon findings from a national evaluation of student social workers' experiences of ‘non-traditional’ placements with a national charity, this article considers what such placements can contribute to the development of an individual and collective sense of professional identity for social work. This is explored against the background of current developments in social work education in England, including changes to the requirements for practice placements and the introduction of ‘fast-track’ routes to qualification, preparing students for social work in statutory children's services. The article suggests that with the establishment of The College of Social Work and the development of the Professional Capabilities Framework, relevant to all social workers throughout their careers, the profession has an opportunity to promote a concept of social work in England beyond that required by statutory sector employers; and that practice learning in non-statutory and non-traditional settings has an important role to play in this.  相似文献

This article describes and highlights the potential contributions that the constructs multifinality, work hope, and possible selves make for designing career counseling interventions and for better understanding possible career‐related factors associated with academic engagement and achievement among urban minority youth. Multifinality may serve as a superordinate orientation because it conceptualizes development as discontinuous and relatively plastic, allowing for youth deemed at risk to follow more hopeful pathways. Work hope and possible selves emphasize the utility of providing urban minority youth with space to answer questions related to what they might achieve and do in the future and who they might become. Together, multifinality, work hope, and possible selves provide a hopeful conceptual framework for career researchers and practitioners.  相似文献

Gutierrez (2006) experimentally demonstrated the effects of joint control and particularly the role of response mediation in the sequencing behavior of adults using an unfamiliar language. The purpose of the current study was to replicate and extend the procedures used by Gutierrez by comparing the effects of joint control training with the effects of a prompt-and-fade procedure on the acquisition of a sequencing task. The effects of each procedure on delayed sequencing behavior were also tested. Ten undergraduate students participated in 2 experiments. The results indicated that all participants acquired the sequencing response in fewer trials and maintained accurate delayed responding when the component responses necessary for joint control were directly taught. Finally, when the self-echoic mediation component was blocked, accurate responding deteriorated in 8 of 10 participants.  相似文献
