价值取向与社会距离影响经济决策的合作与冲突行为：Chicken Game的证据

采用Chicken Game博弈任务,考察了不同社会价值取向个体（亲社会者与亲自我者）在面对不同社会距离的博弈对手（朋友和陌生人）时表现出的合作与冲突行为。研究结果发现：（1）社会价值取向与社会距离交互影响个体的合作与冲突行为;（2）社会价值取向影响选择策略的反应时,亲社会者选择合作的反应时长于选择冲突的反应时,亲自我者选择合作与选择冲突的反应时没有显著差异;（3）无论对亲社会者还是亲自我者,反馈类型都显著影响个体的合作与冲突行为的选择率以及随后决策的反应时。上述结果表明,个体的合作或冲突行为,并非单一地受到社会价值取向的影响,更可能是受到个人因素（社会价值取向）与其他社会因素（比如,社会距离）的共同调节,并且在这一过程中个体会根据决策后反馈信息不断的调整自己的行为策略。     

Exploring diversity effects: nationality composition and nationality context in workgroups

The types of conflict that emerge in nationally diverse teams may depend on the number and types of nationalities present in the team. We investigate the possibility that when teams have individuals from multiple different nationalities (i.e., Dutch, Swiss and Indonesian), rather than just two different nationalities (Dutch and Indonesian), performance and task conflict will be higher while process and relationship conflicts will be comparatively lower. A scenario-based study was conducted in two countries in which we examined how nationality composition (size of national diversity or number of nationalities) and context (nature of national diversity or types of nationalities) affected perceived conflict and expected performance. We hypothesized and found that task conflict and performance are higher in nationally diverse workgroups that included multiple dissimilar nationalities compared to workgroups with just two nationalities. Results also showed that relationship and process conflicts are lower in groups that are diverse in size and nature of national diversity. We observed that social distances among nationalities varied in such a way that a distant nationality became more distanced and a close nationality became even closer in a nationally diverse group. Social distance, in that way, moderated the effect of national diversity. We discuss implications for diversity and conflict management.     

Lower back pain in nurses working in home care: linked to work–family conflict,emotional dissonance,and appreciation?

In industrial countries home care services for elderly people living in the community are growing rapidly. Home care nursing is intensive and the nurses often suffer from musculoskeletal pain. Time pressure and job control are job-related factors linked to the risk of experiencing lower back pain (LBP) and LBP-related work impairment. This survey investigated whether work-family conflict (WFC), emotional dissonance and being appreciated at work have incremental predictive value. Responses were obtained from 125 home care nurses (63% response rate). Multiple linear regression showed that emotional dissonance and being appreciated at work predicted LBP intensity and LBP-related disability independently of time pressure and job control. WFC was not a predictor of LBP-related disability in multiple regression analyses despite a zero-order correlation with it. Redesigning the working pattern of home care nurses to reduce the emotional demands and improve appreciation of their work might reduce the incidence of LBP in this group.     

Investigating cycling kinematics and braking maneuvers in the real world: e-bikes make cyclists move faster,brake harder,and experience new conflicts

Pedelecs (e-bikes), which facilitate higher speeds with less effort in comparison to traditional bicycles (t-bikes), have grown considerably in popularity in recent years. Despite the large expansion of this new transportation mode, little is known about the behavior of e-cyclists, or whether cycling an e-bike increases crash risk and the likelihood of conflicts with other road users, compared to cycling on t-bikes. In order to support the design of safety measures and to maximize the benefits of e-bike use, it is critical to investigate the real-world behavior of riders as a result of switching from t-bikes to e-bikes.Naturalistic studies provide an unequaled method for investigating rider cycling behavior and bicycle kinematics in the real world in which the cyclist regularly experiences traffic conflicts and may need to perform avoidance maneuvers, such as hard braking, to avoid crashing. In this paper we investigate cycling kinematics and braking events from naturalistic data to determine the extent to which cyclist behavior changes as a result of transferring from t-bikes to e-bikes, and whether such change influences cycling safety.Data from the BikeSAFE and E-bikeSAFE naturalistic studies were used in this investigation to evaluate possible changes in the behavior of six cyclists riding t-bikes in the first study and e-bikes in the second one. Individual cyclists’ kinematics were compared between bicycle types. In addition, a total of 5092 braking events were automatically extracted after identification of dynamic triggers. The 286 harshest braking events (136 cases for t-bike and 150 for e-bike) were then validated and coded via video inspection.Results revealed that each of the cyclists rode faster on the e-bike than on the t-bike, increasing his/her average speed by 2.9–5.0 km/h. Riding an e-bike also increased the probability to unexpectedly have to brake hard (odds ratio = 1.72). In addition, the risk of confronting abrupt braking and sharp deceleration were higher when riding an e-bike than when riding a t-bike.Our findings provide evidence that cyclists’ behavior and the way cyclists interact with other road users change when cyclists switch from t-bikes to e-bikes. Because of the higher velocity, when on e-bikes, cyclists appear to have harder time predicting movements within the traffic environment and, as a result, they need to brake abruptly more often to avoid collisions, compared with cycling on t-bikes. This study provides new insights into the potential impact on safety that a cycling society moving to e-bikes may have, indicating that e-cycling requires more reactive maneuvers than does cycling traditional bicycles and suggesting that any distractive activity may be more critical when riding e-bikes compared to traditional bikes.     

Le rôle des stresseurs sur le comportement d’innovation : Quand le leadership habilitant du supérieur protège le potentiel d’innovation des travailleurs

This study focuses on the relationship between workplace stressors and innovative work behavior. The joint analysis of the mediation process supporting this relationship as well as the influence of certain external conditions such as the moderating role of the supervisor has made it possible to highlight the dynamic that underlie the relationship between stressors and innovation behavior. Using the challenge-hindrance model, this theory proposes that challenge (i.e., role overload) and hindrance (i.e., role ambiguity and role conflict) stressors exert positive and negative indirect effects, respectively, on innovative work behavior through psychological empowerment (PE). Furthermore, empowering leadership (EL) has the potential to optimize the benefits of challenge stressors and reduce the effects of hindrance stressors on PE and indirectly on innovation work behavior. In support of these predictions, a time-lagged study of 146 employees from various Canadian firms reveals that hindrance stressors, particularly role ambiguity, are negatively related to innovative work behavior through PE. Moreover, when EL was high, the positive effects of role overload were enhanced through PE while the negative effects of role ambiguity and role conflict were attenuated. The implications of these findings for research and practice are discussed.     

The West Bank “Alternative Peace Movement” and its transnational infrastructure: a case study in “primordialist universalism”

This article provides an overview and theorization of the “Alternative Peace Movement” (APM), a transnational education and advocacy network based in the West Bank. Emerging in the troubled context of current Israel-diaspora relations and US campus politics, the APM promotes a syncretic Jewish identity narrative and boundary-crossing political programme. Drawing on a content and discourse analysis of the movement’s online documentation, as well as interviews with movement leaders, participants, and allies, the article outlines the APM’s infrastructure and discourse, and provides an historical backdrop and set of theoretical tools for rendering comprehensible the movement’s seeming contradictions and incoherencies. It describes the APM as a case study in “primordialist universalism,” a political orientation that aims to pursue civic and human rights of a universal character by inhabiting a “hard” ethnonational subjectivity and discursive frame. The concept of primordialist universalism offers social scientists a tool for making sense of hybrid social phenomena that confound traditional categories of political analysis.     

Agents of Prosociality: Agency Affirmation Promotes Mutual Prosocial Tendencies and Behavior Among Conflicting Groups

Members of conflicting groups are motivated to restore their ingroup's agency, leading to antisocial tendencies against the outgroup. The present research tested the hypothesis that affirming conflicting groups' agency would increase their members' mutual prosociality. The effectiveness of agency affirmation was demonstrated in three contexts of conflict between groups: Switzerland and the EU following the 2014 referendum (Study 1), Israelis and Palestinians (Study 2), and Israeli rightists and leftists (Study 3). Study 1 found that in a nonconflictual context Swiss participants prioritized their moral (prosocial) over agentic goals, yet in the context of conflict with the EU, they prioritized their agentic over moral goals. This “primacy‐of‐agency” effect, however, was eliminated once their ingroup's agency was affirmed. Studies 2 and 3 demonstrated the positive effect of agency affirmation on prosociality among Israelis referring to Palestinians and Israeli rightists and leftists referring to the adversarial political camp. This effect was mediated by group members' readiness to relinquish some power for the sake of morality. Pointing to the importance of the affirmation's specific content, Studies 2 and 3 demonstrated that morality affirmation failed to increase prosociality. As such, the present research puts forward a promising strategy to reduce hostility and promote prosociality between conflicting groups.     

Dietary planning,self-efficacy,and outcome expectancies play a role in an online intervention on fruit and vegetable consumption

Objective: An online intervention to improve fruit and vegetable (FV) intake examines the role of planning, outcome expectancies, self-efficacy and gender. Women are not only expected to eat more FV than men, but they are also expected to be more responsive to nutritional advice and benefit more from treatment.

Method: A two-arm digital intervention with 269 men and 395 women (M_age = 41.2, SD_age = 11.45; range: 19–66 years) was conducted in Italy, Spain and Greece, followed up at three and six months, comparing a static with a dynamic, feedback-intensive platform.

Results: Linear mixed models yielded an increase in FV consumption in both the dynamic and the static intervention arms. In men, outcome expectancies were positively related to follow-up FV intake. Dietary planning interacted with self-efficacy on behavioural outcomes.

Conclusion: FV intake increased overall, and being a woman and involvement in planning facilitated behaviour change. Women seemed to be more engaged in the dynamic platform resulting in a higher amount of planning. Initial motivation, as indicated by outcome expectancies, seemed to be beneficial for men. Self-efficacious individuals benefitted from their engagement in planning, but self-efficacy did not compensate for failing to plan.     

The role of retributive justice and the use of international criminal tribunals in post‐conflict reconciliation

Four experiments examined people's responses to intergroup violence either committed or suffered by their own group. Experiment 1 demonstrated that Serbs who strongly glorified Serbia were more supportive of future violence against, and less willing to reconcile with, Bosniaks after reading about Serbian victimization by Bosniaks rather than Serbian transgressions against Bosniaks. Replicating these effects with Americans in the context of American–Iranian tensions, Experiment 2 further showed that demands for retributive justice explained why high glorifiers showed asymmetrical reactions to ingroup victimization vs. perpetration. Again in the Serb and the American context, respectively, Experiments 3 and 4 demonstrated that post‐conflict international criminal tribunals can help satisfy victim group members' desire for retributive justice, and thereby reduce their support for future violence and increase their willingness to reconcile with the perpetrator group. The role of retributive justice and the use of international criminal justice in intergroup conflict (reduction) are discussed.
