云南边疆少数民族间的"康吧"经济交往模式:理论与实证分析

"康吧"交往是纳西族与傈僳族、藏族之间一种独特而历史悠久的物质交换模式,它不符合理性选择的逻辑却能世代延续至今,同时,不同民族间的"康吧"交往又存在差异。本文借鉴西方主流理论对这种古老的交往模式进行分析,从经济学、社会学、人类学的多重理论角度出发,采用访谈、观察与定量分析相结合的研究方法,对上述现象进行了分析。研究结果表明:(1)资源依赖性、信任和互惠原则对"康吧"交往的延续至关重要;(2)货币市场和投机行为的出现导致"康吧"交往走向衰落,但情感互惠和资源互补使之至今存在;(3)自然资源条件、资源互补程度、社会历史背景和文化因素,对交往模式的差异都有重要影响作用。     

Dopamine and risk choices in different domains: Findings among serious tournament bridge players

We explore how risk-taking in the card game contract bridge, and in a financial gamble, correlate with variation in the dopamine receptor D4 gene (DRD4) among serious tournament bridge players. In bridge risk-taking, we find significant interactions between genetic predisposition and skill. Among men with the 7-repeat allele of DRD4, namely 7R + men, those with more bridge skill take more good risks and fewer bad risks, while the opposite is found for less-expert 7R + men. Conversely, skill does not predict risk-taking among men without the 7R + allele. Consistent with some prior studies, we also find that 7R + men take more risk in the financial gamble. We find no relationship between 7R + and either risk measure among our female subjects. Our results suggest that the dopamine system plays an important role in individual differences in risk-taking among men, and is the first to distinguish between advantageous and disadvantageous risk-taking.     

Racial/ethnic disparities in US college students’ experience: Discrimination as an impediment to academic performance

ABSTRACT

Objective and Participants: Using data from 69,722 US undergraduates participating in the spring 2015 National College Health Assessment, we examine racial/ethnic differences in students’ experience of discrimination. Method: Logistic regression predicted the experience of discrimination and its reported negative effect on academics. Additional models examined the effect of attending a Minority Serving Institution (MSI). Results: Discrimination was experienced by 5–15% of students, with all racial/ethnic minority groups examined- including Black, Hispanic, Asian, AI/NA/NA, and Multiracial students- more likely to report discrimination relative to White students. Of students who experienced discrimination, 15–25% reported it had negatively impacted their academic performance, with Hispanic and Asian students more likely to report negative impacts relative to White students. Attending an MSI was associated with decreased experiences of discrimination. Conclusion: Students from racial/ethnic minority backgrounds are disproportionately affected by discrimination, with negative impacts for academic performance that are particularly marked for Hispanic and Asian students.     

Field Note—From MSW to J-O-B: Using Field Seminar to Prepare Students for Employment

ABSTRACT

Social work field education is expected to help students transition from the classroom to the practice setting. Yet, few social work programs adequately provide career development support to increase students’ employability. This Field Note presents practical, relevant and immediate strategies for implementing the MSW to J-O-B curriculum innovation in the field practicum seminar. The purpose is to help students clarify professional goals and successfully obtain employment or career advancement opportunities following graduation. Formative evaluation results for this professional development curriculum are presented.     

Game-Based Cognitive-Behavioral Therapy (GB-CBT) Group Program for Children Who Have Experienced Sexual Abuse: A Preliminary Investigation

This preliminary investigation examined the efficacy of a game-based cognitive-behavioral therapy group program for elementary school-aged children who have experienced sexual abuse. Treatment aimed to improve: (a) internalizing symptoms, (b) externalizing behaviors, (c) sexually inappropriate behaviors, (d) social skills deficits, (e) self-esteem problems, and (f) knowledge of healthy sexuality and self-protection skills. Results indicate that game-based cognitive-behavioral therapy was effective for improving internalizing and externalizing symptoms, reducing sexually inappropriate behaviors, and improving children's knowledge of abuse and self-protection skills. Although results pointed in a positive direction for social skills and self-perception, these findings were not statistically significant. Clinical significance was also evaluated to assess the clinical utility of treatment effects. Treatment implications of the findings and future research directions are discussed.     

企业社会责任行为中的战略管理视角理论综述

基于组织对企业社会责任(CSR)表现出的不同态度和内在动机,将企业的CSR行为划分为强制性、回应性、战略性和利他性4种类别,并在此基础上对相关理论进行回顾。通过对以往研究的比较总结,认为CSR行为在本质上作为企业的一种战略决策,受到内外部环境的共同影响并与之协同演进。由此,首次将战略管理中的协同演进观引入CSR研究,建立起CSR行为战略与组织绩效相互作用的协同演进模型,并在此模型基础上提出了下一步理论和实证研究的方向。
