安全动机在安全绩效模型中的作用：自我决定理论的视角

在日常工作中, 安全动机是员工保持安全行为的重要决定因素。安全动机对安全绩效的影响虽然已引起研究者的关注, 但相关的实证研究缺少清晰的理论界定和有效的测量工具。本项目拟在安全绩效模型的基础上, 借鉴自我决定理论对动机的分类, 将安全动机的类型进行扩展, 并在多层次模型中探讨安全动机在变革型领导、个体特征和安全绩效之间的中介作用, 以及在中国管理背景下可能存在的边界条件。研究将结合访谈、问卷和情境实验等方法对上述变量间关系进行相关和因果关系的探讨。本项目将自我决定理论与安全绩效模型相结合, 可以为安全研究的动机理论发展做出贡献; 研究结果亦可为安全管理实践提供评价工具和有效指导。     

心理距离与后果严重性对人身安全决策的影响

已有研究发现决策者在为自己与不同他人决策时,其风险偏好存在差异。但是当对后果严重性不同的事件进行决策时,上述结果也并不总是如此。为了探究在人身安全情境中决策者面对后果严重程度不同的任务时,为自己和为他人决策时风险偏好的差异,实验一采用人际亲密度和决策所带来消极结果的严重程度分别操纵心理距离与后果严重性,结果发现决策者在后果严重任务中的决策比后果不严重任务更保守,为自己和为陌生人决策均比为最好朋友决策更冒险。这可能是由于决策者知觉到的决策责任不同所致。因此在实验一的基础上实验二引入决策责任这一变量,考察其在心理距离对风险决策影响中的作用,研究结果证明了我们的假设。     

The Effect of Residential Neighborhood on Child Behavior Problems in First Grade

Child behavior problems have been identified as being responsible for the greatest reduction in quality of life for children between ages 1 and 19. In this study, we examine whether neighborhood social processes are associated with differences in child behavior problems in an economically and racially diverse sample of 405 urban-dwelling first grade children and whether parenting behavior mediates and/or moderates the effects of neighborhoods. Furthermore, we examine whether neighborhood social processes play the same role with regards to child behavior problems at differing levels of neighborhood economic impoverishment. Results of multivariate multilevel regression analyses indicate that a high negative social climate is associated with greater internalizing problems. High potential for community involvement for children in the neighborhood was associated with fewer behavior problems, but only in economically impoverished neighborhoods. Differences in parenting behavior did not appear to mediate neighborhood effects on behavior problems, and parenting characterized by a high degree of positive involvement was associated with fewer behavior problems in all types of neighborhoods.     

Using real-time visual feedback to improve posture at computer workstations

The purpose of the current study was to examine the effects of a multicomponent intervention that included discrimination training, real-time visual feedback, and self-monitoring on postural behavior at a computer workstation in a simulated office environment. Using a nonconcurrent multiple baseline design across 8 participants, the study assessed the effects of the intervention across three postural variables. Following an information phase, the intervention started for the lowest stable postural variable. The intervention led to substantial improvements in safety behavior for most targeted postural variables. A reversal to the information phase for 2 participants did not lead to decreases in safety. Postures self-monitored with high accuracy improved to a greater degree than postures self-monitored with low accuracy.     

Peer tutoring to prevent firearm play acquisition, generalization, and long-term maintenance of safety skills

Hundreds of accidental injuries and deaths to children occur annually in the United States as a result of firearm play. Behavioral skills training (BST) and in situ training have been found to be effective in teaching children the skills to use if they find a firearm, but training requires substantial time and effort. The current study examined the use of peers as tutors as a potential way to decrease the time and resources needed to teach these safety skills to youngsters. Peer trainers conducted BST and in situ training with other children. Children taught by the peer trainers acquired the safety skills and demonstrated them in naturalistic situations in which the skills were needed. Furthermore, all of the peer trainers acquired and maintained the skills. These results support the use of peer tutoring for teaching safety skills to other children.     

Substance Use and Health and Safety among Homeless Youth

This study examines how substance use is associated with the health and safety of homeless youth using cross-sectional, self-report data from 285 homeless adolescents. Path models were used to examine concurrent relationships between youth’s substance use and multiple aspects of their health and safety, including measures of psychological distress, housing risk and instability, and medical problems. Substance use was examined with both global (i.e., a composite of days of use across various drugs and alcohol) and specific (i.e., rates of use of specific drugs, injection drug use) measures. After controlling for demographic and historical variables, number of days of use was significantly related to psychological distress, whereas injection drug use was significantly related to housing risk. Examination of specific drugs revealed relationships between psychological distress and the use of alcohol, cocaine, and amphetamines, and a specific relationship between housing risk and the use of heroin. None of the measures of substance use was significantly related to youth’s medical problems. Implications for interventions with homeless adolescents are discussed.     

An examination of message-relevant affect in road safety messages: Should road safety advertisements aim to make us feel good or bad?

Drawing upon the multiple roles of affect posited by Elaboration Likelihood Model, the current paper examines the effectiveness of message-relevant affect. Specifically, humourous and fear-evoking anti-drink driving messages are examined in terms of perceptions of relative influence on self and others (i.e., the third-person effect) and their performance on a range of persuasion outcomes. The influence of involvement, response efficacy, and gender on persuasion outcomes is also examined. Participants (N = 201) viewed two advertisements and completed two questionnaires: the first, assessed pre-exposure attitudes and behaviour and immediate-post exposure attitudes and intentions; the second, 2–4 weeks later, assessed attitudes and behaviour. The results revealed, as predicted, interactions of the key variables and evidence of the greater persuasiveness of negative appeals immediately after exposure whilst greater improvement of positive appeals over time. The findings highlight the importance of continuing the exploration of positive appeals as a persuasive alternative to negative appeals.     

The role of bystanders in students' perception of bullying and sense of safety

Two studies employing a mixed experimental design were conducted to determine if perceptions of bullying, attitudes towards victims, and students' sense of safety at school were influenced by bystanders' reactions to different types of bullying. In Study 1, 217 middle-school children were randomly assigned to read a hypothetical scenario describing a direct bullying episode. In Study 2, 376 primary-school children and 390 middle-school children were presented with scenarios describing a direct bullying episode and an indirect bullying episode. In all scenarios, the bystanders' reactions to the bullying and the gender of the victim were manipulated. Participants endorsed the prosocial behavior in favor of the victims and did not endorse pro-bullying behavior. Furthermore, they perceived passive reactions to the bullying as negative behavior. Participants showed positive attitudes towards victims, which were significantly higher at younger grade levels and among girls. Bystanders' behavior influenced both participants' perceptions of the victims and their perceived sense of safety at school. Implications for anti-bullying programs based upon the group ecology are discussed.     

RELIABILISM AND SAFETY

Abstract: Duncan Pritchard has recently highlighted the problem of veritic epistemic luck and claimed that a safety‐based account of knowledge succeeds in eliminating veritic luck where virtue‐based accounts and process reliabilism fail. He then claims that if one accepts a safety‐based account, there is no longer a motivation for retaining a commitment to reliabilism. In this article, I delineate several distinct safety principles, and I argue that those that eliminate veritic luck do so only if at least implicitly committed to reliabilism.     

A strategy for assessing closure

This paper looks at an argument strategy for assessing the epistemic closure principle. This is the principle that says knowledge is closed under known entailment; or (roughly) if S knows p and S knows that p entails q, then S knows that q. The strategy in question looks to the individual conditions on knowledge to see if they are closed. According to one conjecture, if all the individual conditions are closed, then so too is knowledge. I give a deductive argument for this conjecture. According to a second conjecture, if one (or more) condition is not closed, then neither is knowledge. I give an inductive argument for this conjecture. In sum, I defend the strategy by defending the claim that knowledge is closed if, and only if, all the conditions on knowledge are closed. After making my case, I look at what this means for the debate over whether knowledge is closed.
