美国对受试者研究中特殊挑战的观点:遗传研究中的伦理问题

虽然基因研究比其他任何时候更有望了解人类疾病及其在世界各类人群中的表现形式,并且对预防和治疗疾病产生了深远影响,但是它的应用也会极大地改变我们对个体及群体特征。从个体属性及群体意识的角度来看,特别是关于知情同意这个议题,我们会非常清楚地看到遗传研究所面临的挑战。阐述了在美国遗传研究所面临的挑战,讨论了遗传研究进行过程中出现的一系列伦理问题,如：如何正确执行知情同意;研究中可能对受试者产生的标签和歧视行为;遗传流行病研究中出现的伦理问题以及需要关注的社区和民族的伦理问题;对人类组织样本的储存和使用中所出现的伦理问题。强调了知情同意和社区参与遗传研究及在研究中社区代表性的重要性;强烈主张在遗传研究中建立多民族的合作是确保研究的顺利进行的基础。     

Does parochial cooperation exist in childhood and adolescence? A meta-analysis

Although previous meta-analytic evidence supports the existence of parochialism in cooperation among adults, the extent to which children and adolescents are more willing to incur a personal cost to benefit ingroups, compared to outgroups, is not yet clear. We provide the first meta-analysis on the existence and magnitude of parochialism in cooperation among pre-adults. Based on 20 experimental economics studies (k = 69, N = 5268, age = 3–19, 12 countries, published 2008–2019), a multilevel meta-analytic model revealed a small overall effect size indicating that children and adolescents were more cooperative towards ingroups (d = 0.22, 95% CI [0.07, 0.38]). A series of single-moderator analyses tested for the following conditions: participant age and sex; game type ([mini-]dictator game, prisoner's dilemma, public goods dilemma, trust game, ultimatum game); outcome interdependence; membership manipulation (between- vs. within-subjects); group type (natural vs. experimental); reward type (monetary vs. non-monetary); and country of the participant. Parochial cooperation did not vary with participants' age. Parochialism was larger in non-interdependent (dictator-type) compared to interdependent (bargaining and social dilemma) games. There were no moderating effects of group type, membership manipulation or reward type. To provide more data on how parochialism develops, primary studies should report age ranges more precisely and use more restricted age groups.     

临时知识型员工自主性动机激发：关系导向人力资源管理建构及其作用机理

快速变化的技术需求使得人才外部化, 人才共享成为组织获取技能型、知识型人才的重要方式。共享经济背景下的人力资源管理属于新兴研究领域, 企业在管理临时知识型员工面临很大挑战。由于身份的外部性、临时性, 员工关系基础薄弱, 临时知识型员工专业能力发挥受限, 工作场所关系需求受阻, 导致自主性动机不足, 影响绩效产出, 而传统对外部员工的契约型管理难以解决以上问题。针对嵌入团队工作的临时知识型员工, 研究基于关系型协调理论探索关系导向人力资源管理实践构成。在此基础上, 结合自我决定理论探讨关系导向人力资源管理实践提升临时知识型员工绩效的作用机理, 验证从自主性动机来源、自主性动机激发到自主性动机结果的路径机制。对关系导向人力资源管理实践内容和效用探讨有助于深入理解临时知识型员工的管理, 为共享经济背景下新型用工管理实践提供启示。     

THE WICKED PROBLEM OF OUR FAILING SOCIAL COMPACT

The United States is an outlier among nations in its failure to adopt robust climate policy. The underlying cause is not unique to the climate issue. Climate, like growing national debt, embodies a trade‐off between individual consumption now versus investment yielding long‐term societal gain. Over human history, social norms favoring one over the other wax and wane with the pervasiveness of transcendental values as embodied in personal virtue, social connectedness, spirituality, and religious faith. Over the past few decades, many indicators show that American social norms and extended cooperation have weakened. Given entrenched political corruption and continuing institutional failure to address multiple long‐term societal challenges, individuals are called upon personally to practice and to enforce pro‐social norms and to advance high‐leverage systemic changes, some identified in this article, which will allow extended cooperation to once again flourish.     

正常人以及精神障碍人群在合作与竞争中的表现

合作与竞争是社会互动的两种主要形式,也是冲突解决的两种方法,对人际交往具有重要作用,一直以来都受到研究者的广泛关注。但是从心理与社会学角度研究合作与竞争的文献却相对较少,而对于精神障碍人群在合作与竞争中异常表现的原因目前也存在争议。本文从心理与社会学的角度出发,对合作与竞争的神经机制和生物基础进行综合论述,并对精神障碍人群在合作与竞争两种社会互动中的表现进行比较,试图为精神障碍人群在人际交往中的康复训练提供理论依据。     

Cautious Defection: Group Representatives Cooperate and Risk Less than Individuals

Individuals often make decisions that affect groups, yet the propensities of group representatives are not as well understood than those of independent decision makers or deliberating groups. We ask how responsibility for group payoffs—in the absence of group deliberation—affects the choice. The experiment utilizes the Interdependent Security Dilemma paradigm. In its deterministic version, the game is identical to a finitely repeated Prisoner's Dilemma. In the stochastic version, potential losses are larger but uncertain, occurring with a predefined probability when one or both players choose to forgo investment in protection. Participants were assigned to play either as individuals, or as representatives of three‐person groups, with each member's choices equally likely to determine the group's payoffs. In the deterministic condition, individuals were more likely to invest (cooperate) than group representatives (80% vs. 62% of rounds). In the stochastic condition, the pattern was reversed as representatives were slightly, but not significantly, more likely to invest than individuals (46% vs. 40%). The significant interaction effect suggested that group representatives were not only less cooperative but also more risk averse than individuals. A follow‐up study supported this account by showing participants who construed the invest strategy as low‐risk than those who perceived this strategy to be high risk. Overall, group representatives exhibited a tendency to act more competitively and more cautiously than individuals acting alone. Copyright © 2015 John Wiley & Sons, Ltd.     

双侧梭状回面孔区在面孔加工中的功能分工与协作

梭状回面孔区(fusiform face area,FFA)是视觉皮层上专门加工面孔的区域。然而,双侧FFA在面孔加工中的功能分工与协作还存在争议。在特异性刺激的加工上,右侧FFA主要负责人类面孔类别的知觉,而左侧FFA的功能与面孔精细特征的感知有关;在皮层可塑性上,右侧FFA主要参与青少年的社会适应学习,而左侧FFA负责成年人的知觉学习;在面孔网络中,二者与不同区域的连接用以适应不同的认知需求;他们之间的有向协作具有任务特定性。未来研究需要回答三个问题:左侧FFA的可塑性程度及这一可塑性是否是认知特定的、左侧FFA及其形成的网络连接的认知意义,双侧FFA在面孔网络中的连接有向性等问题。     

Cooperative responding in rats maintained by fixed‐ and variable‐ratio schedules

The present study investigated the effects of fixed‐ratio (FR) and variable‐ratio (VR) reinforcement schedules on patterns of cooperative responding in pairs of rats. Experiment 1 arranged FR 1, FR 10, and VR 10 schedules to establish cooperative responding (water delivery depended on the joint responding of two rats). Cooperative response rates and proportions were higher under intermittent schedules than under continuous reinforcement. The FR 10 schedule generated a break‐and‐run pattern, whereas the VR 10 schedule generated a relatively high and constant rate pattern. Experiment 2 evaluated the effects of parametric manipulations of FR and VR schedules on cooperative responding. Rates and proportions of cooperative responding generally increased between ratio sizes of 1 and 5 but showed no consistent trend as the ratio increased from 5 to 10. Experiment 3 contrasted cooperative responding between an FR6 schedule and a yoked control schedule. Coordinated behavior occurred at a higher rate under the former schedule. The present study showed that external consequences and the schedules under which the delivery of these consequences are based, select patterns of coordinated behavior.     

The Pentecostal Church in Slovakia and the Common Witness of Evangelical Churches in the Spirit of Partnership and Cooperation

This study aims to describe the Pentecostal Church in Slovakia in the scope of current ecumenical cooperation and dialogue. The Apostolic Church is a member of the Union of Evangelical Churches in Slovakia, which established the Department of Theology and Christian Education (DETM) at the University of Matej Bel. Since 1994, individual churches have continued together in ecumenical cooperation in the education of their young spiritual workers. The curriculum includes academic interpretation and missiological reflection on selected parts of mission. It offers the practical efforts of the teachers and students, especially from the viewpoint of the churches' common witness in diversity. The curriculum of the study programme for theologians interprets the two mission documents Together towards Life (TTL) and The Cape Town Commitment (CTC) from a Slovakian evangelical theological view and applies it practically in context. This paper introduces DETM's educational programme in mission and ecumenism and examines how it embodies the values and concepts of those two mission documents through its activities. Special interest is focused on the topic of the practice of common witness in a spirit of partnership and cooperation.
