风险情景中不同成就动机者的冒险行为特征

采用计算机模拟和问卷的方法,研究不同成就动机的个体在动态情境下的冒险行为。结合成就动机的静态与动态理论,考察具有不同程度的成就动机个体在动态环境中的行为差异。结果发现,在动态情境的初期,可以看到不同成就动机的被试有稳定的偏好：成就动机高的个体偏爱中等难度的任务,成就动机低的个体偏爱较易或者是较难难度的任务;随着行为的动态进行,个体的冒险行为呈现出与静态情境中不同的规律性：成就动机高的个体在初期选择的中等难度的基础上逐渐选择更难的任务;成就动机低的个体在初期选择较易难度任务的基础上也逐渐选择更难的任务;相对于成就动机低的个体,成就动机高的个体会更慢地选择难度高的任务;高成就动机个体出现非典型转换次数显著低于低成就动机的个体。     

‘Additive difference’ models without additivity and subtractivity

This paper studies conjoint measurement models tolerating intransitivities that closely resemble Tversky's additive difference model while replacing additivity and subtractivity by mere decomposability requirements. We offer a complete axiomatic characterisation of these models without having recourse to unnecessary structural assumptions on the set of objects. This shows the pure consequences of several cancellation conditions that have often been used in the analysis of more traditional conjoint measurement models. Our models contain as particular cases many aggregation rules that have been proposed in the literature.     

Generic statements require little evidence for acceptance but have powerful implications

Generic statements (e.g., "Birds lay eggs") express generalizations about categories. In this paper, we hypothesized that there is a paradoxical asymmetry at the core of generic meaning, such that these sentences have extremely strong implications but require little evidence to be judged true. Four experiments confirmed the hypothesized asymmetry: Participants interpreted novel generics such as "Lorches have purple feathers" as referring to nearly all lorches, but they judged the same novel generics to be true given a wide range of prevalence levels (e.g., even when only 10% or 30% of lorches had purple feathers). A second hypothesis, also confirmed by the results, was that novel generic sentences about dangerous or distinctive properties would be more acceptable than generic sentences that were similar but did not have these connotations. In addition to clarifying important aspects of generics' meaning, these findings are applicable to a range of real-world processes such as stereotyping and political discourse.     

Une étude sur le rôle modérateur des traits de personnalité sur la relation entre les conditions de l’organisation du travail et la détresse psychologique

This study is about psychological distress lived by Canadian workers. Only a few studies considered personal traits in the comprehension of this phenomenon. This study aims to determine the moderator role of self-esteem, the sense of control and the sense of cohesion on the relation between the work organization conditions and psychological distress. Some longitudinal data (n=7338 workers) coming from five cycles (1994-2003) of the National Population Health Survey (NPHS) have been used to complete some multilevel analysis (n1=time and n2=individual). The results indicate that the sense of control and the sense of cohesion play a moderator role on the relation between some of the work organization conditions and the level of psychological distress.     

Collective Efficacy as a Key Context in Neighborhood Support for Urban Youth

Neighborhood context, including the physical and social environment, has been implicated as important contributors to positive youth development. A transactional approach to neighborhood asserts that place and people are mutually constitutive; negative perceptions of place are intrinsically bound with negative portrayals of stigmatized groups, including youth. Adult perceptions of neighborhood youth may contribute to an increased sense of alienation and youth antisocial behavior. This study uses street‐intercept interviews with adults (N = 408) to examine the relationship between neighborhood conditions and adult support for neighborhood youth. A path model was used to examine the direct and indirect relationship of neighborhood constructs (safety, aesthetic quality, and walkability) on adult support for neighborhood youth. Neighborhood aesthetic quality and the walking environment were directly associated with adult support for youth, whereas perceived safety was indirectly associated. Collective efficacy partially explained these relationships. Findings support theorized relationships between people and places; improvements to neighborhood physical environment may directly impact resident adults’ perceptions of neighborhood young people.     

工作场所领导愤怒的有效性及其作用机制

领导愤怒(leader anger)作为最常见、最易被感受到的工作场所负面情绪之一, 对于改善工作关系、行为和绩效具有显著影响。然而, 已有文献关于领导愤怒阻碍还是促进领导有效性的观点存在许多争议, 对于领导愤怒为什么以及何种条件下影响领导有效性的问题尚不明确。在回顾工作场所领导愤怒概念起源和内涵特点的基础上, 从消极效应和积极效应双刃视角厘清了工作场所领导愤怒的有效性, 基于情绪即社会信息理论阐释了工作场所领导愤怒有效性的双路径中介机制, 并从个体/团队/组织三层面分析了领导愤怒有效性的边界条件。未来研究应从工作场所领导愤怒的概念和结构测量、事件前因和后果、中介机制、情境因素、研究方法和研究层面等方面进一步拓展。     

Having both hands on the steering wheel: Driving behaviour of white-collar workers with degenerative eye conditions

Because people in the United States are highly reliant on cars for transportation, individuals with restricted driving abilities face severe accessibility constraints in the labour market. Guided by the social exclusion framework, we used a qualitative approach to gain insights into the role of car driving and alternative commute modes in the lives of white-collar workers with degenerative eye conditions. The study participants gradually restricted their driving behaviour as the disease progressed. They also exhibited several types of commute solutions, which lent themselves to a variation in the experienced degree of exclusion (both between participants and within participants over time), with changes in vision state and available resources. Another aim of our study was to identify the motivations for driving behaviour. The results showed that while a desire to reduce the risk of an accident motivated the participants to stop driving, certain normative (for men) and practical considerations motivated participants to continue driving. While all of the participants eventually stopped driving due to vision decline, the decision to quit often occurred only after the participants experienced one or more car accidents. Workplace accessibility is a factor that hinders labour market participation of individuals with degenerative eye conditions and encourages individuals to engage in risky behaviour.
