虚拟团队学习效能研究:社会认知因素的影响

本研究采用现场研究的方法,对21个虚拟团队学习的效能进行了实证研究。研究对社会认知因素中的效能感和目标取向对虚拟团队学习效能(技能改变、工作任务和团队健康水平)的影响进行了研究,并探讨了对虚拟团队的态度在中间所起的作用。研究发现,虚拟团队效能感和学习取向对虚拟团队的学习效能产生作用,而对虚拟团队学习的态度、团队信任对虚拟团队学习的效能起着中介或直接的作用。     

信任倾向与主观参照对网上购物意向的影响

该研究对225名大学生、在职人员进行问卷调查,通过分层回归分析探讨了信任倾向与主观参照对网上购物意向的影响。结果表明:男性在职人员的信任倾向要显著大于男大学生的信任倾向,而对于女性,这种差异不显著。工作与否、性别、学历在信任倾向、主观参照以及网上购物意向上差异不显著。主观参照对网上购物意向的影响受到信任倾向的缓冲,相对于高信任倾向的人,低信任倾向人的网上购物意向更容易受到主观参照的影响。信任倾向和主观参照对网上购物意向都有显著影响,但主观参照的回归效应更大。     

临床试验中的利益冲突：伦理和政策问题

人们对于研究人员、赞助商和研究机构三者之间的经济利益关系给予越来越多的关注,人体试验研究中的经济利益与其他利益有所不同,这种经济利益会导致偏见或诱导不正当的行为,尤其是当有从研究中获益的机会存在时,将会影响到研究人员关于应该选择哪个受试者,应该提供给受试者什么样的医疗服务,甚至应该如何正确使用受试者保密的健康信息方面的判断,由经济利益引起的明显的风险同样也会威胁公众的学术机构研究使命的支持,从处理临床试验中利益冲突的准则,什么样的经济利益是研究中的重大经济利益。准则的实施等方面进行了详尽的叙述,最后指出没有潜在受试者和公众的信任,我们就不能有效地开展研究。     

Relational Risk and Its Personal Correlates in Strategic Alliances

In this study we focus on the perception of one particular type of risk in the context of strategic alliances—relational risk. Perceived relational risk refers to the degree to which decision makers are concerned with the partner's opportunistic behavior in cooperative efforts. We develop a measure of relational risk in strategic alliances, and empirically examine some of its personal correlates. Based on a survey of senior executives of corporations and MBA students, we found partial support for the principal hypothesis that the perception of relational risk for prospective strategic alliances is related to an individual's age and trust in people.     

价格框架对不同认知闭合需要者在线动态价格的感知与购买意愿的影响*

采用问卷与实验相结合的方法,以112名大学生为被试,考察价格框架对不同认知闭合需要者在线购物时对动态定价策略下的价格感知与购买意愿的影响。结果发现：（1）相比非动态价格,动态价格条件下消费者感知价格公平感、购买意愿都较低;（2）在打折框架下,高认知闭合需要者对采取动态价格在线购物网站的感知信任显著好于非动态价格,而低认知闭合需要者则相反,说明消费者的价格感知受这三个变量的综合影响;（3）在降价框架下,认知闭合需要与动态价格的交互作用不显著,意味着在线消费者的购买意愿可能受到更多其它因素制约。     

The effects of perceived phenotypic racial stereotypicality and social identity threat on racial minorities’ attitudes about police

This study examines the role of perceived phenotypic racial stereotypicality and race-based social identity threat on racial minorities’ trust and cooperation with police. We hypothesize that in police interactions, racial minorities’ phenotypic racial stereotypicality may increase race-based social identity threat, which will lead to distrust and decreased participation with police. Racial minorities (Blacks, Latinos, Native Americans, and multi-racials) and Whites from a representative random sample of city residents were surveyed about policing attitudes. A serial multiple mediation model confirmed that racial minorities’ self-rated phenotypic racial stereotypicality indirectly affected future cooperation through social identity threat and trust. Due to the lack of negative group stereotypes in policing, the model did not hold for Whites. This study provides evidence that phenotypic stereotypicality influences racial minorities’ psychological experiences interacting with police.     

Toward a Philosophy of Blockchain: A Symposium: Introduction

This article introduces the symposium “Toward a Philosophy of Blockchain,” which provides a philosophical contemplation of blockchain technology, the digital ledger software underlying cryptocurrencies such as bitcoin, for the secure transfer of money, assets, and information via the Internet without needing a third‐party intermediary. The symposium offers philosophical scholarship on a new topic, blockchain technology, from a variety of perspectives. The philosophical themes discussed include mathematical models of reality, signification, and the sociopolitical institutions that structure human life and interaction. The symposium also investigates the metaphilosophical theme of how to create a philosophy of anything, specifically a new topic such as blockchain technology. Repeated themes are identified, in all areas of philosophical inquiry (ontology, epistemology, and axiology), and conceptual resources are elaborated to contribute to a philosophical understanding of blockchain technology. Thus, philosophy as a metaphilosophical approach is shown to be able to provide an understanding of the conceptual, theoretical, and foundational dimensions of novelty and emergence in the world, with a particular focus on blockchain technology.     

Thieves of thankfulness: Traits that inhibit gratitude

If gratitude is important to well-being, it is important to understand the factors that might inhibit gratitude. The purpose of this study was to investigate four putative inhibitors of gratitude: narcissism, cynicism, materialism/envy, and indebtedness. We used a prospective design where participants were administered measures related to the putative inhibitors along with trait and state gratitude, 2 months apart. After controlling for initial levels of gratitude, Time 1 narcissism, cynicism, and materialism/envy were negatively associated with Time 2 state gratitude. Evidence also supported the theory that narcissism and cynicism may interact in a vicious cycle over time. We conclude that narcissism, cynicism, and materialism inhibit state gratitude, and narcissism and cynicism may be the foundational ‘thieves of thankfulness.’     

Effects of Gender on Costly Punishment

Women are often believed to be more cooperative and less egoistic than men. In the present study, we examined whether people punish women for failing to live up to these benevolent gender stereotypes. Participants played a prisoner's dilemma game with female and male partners who either cooperated or defected. Participants were offered a costly punishment option. They could spend money to decrease the payment of their partners. In Experiment 1, participants spent more money to punish the defection of female in comparison to male partners, but this effect of partner gender on punishment was indirect rather than direct: Participants were more likely to cooperate with female partners than with male partners, which gave them more opportunity for moralistic punishment. In Experiments 2 and 3, we examined the effects of the participants' own gender on cooperation and punishment of female and male partners. Female participants cooperated more with female partners than with male partners while male participants treated female and male partners equally. We conclude that the effect of facial gender on punishment are indirect rather than direct. The results also showed that women, in contrast to men, tended to make decisions that can be considered more social and less rational from an economic point of view, consistent with social‐role theory and evolutionary accounts.

Antecedents of trust in the sharing economy: A systematic review

Users and potential users of the sharing economy need to place a considerable amount of trust in both the person and the platform with which they are dealing. The consequences of transaction partners’ opportunism may be severe, for example damage to goods or endangered personal safety. Trust is, therefore, a key factor in overcoming uncertainty and mitigating risk. However, there is no thorough overview of how trust is developed in this context. To understand how the trust of users in the sharing economy is influenced, we performed a systematic literature review. After screening, 45 articles were included in a qualitative synthesis in which the results were grouped according to a well‐established trust typology. The results show various antecedents of trust in the sharing economy (e.g. reputation, trust in the platform, and interaction experience) related to multiple entities (i.e. seller, buyer, platform, interpersonal, and transaction). Trust in this economy is often reduced to the use of reputation systems alone. However, our study suggests that trust is much more complex than that and extends beyond reputation. Furthermore, our review clearly shows that research on trust in the sharing economy is still scarce and thus more research is needed to understand how trust is established in this context. Our review is the first that brings together antecedents of trust in online peer‐to‐peer transactions and integrates these findings within an existing framework. Additionally, the study suggests directions for future research in order to advance the understanding of trust in the sharing economy.
