A variation of the ABAB experimental design was used to assess the impact of a verbal prompt on safety-belt use for those traveling by urban roads and highways in Spain. The personal prompt resulted in an increase (29.6%) in safety-belt use among drivers traveling on urban roads. This research shows that the impact of personal prompts can be generalized to cultures outside the United States. 相似文献

An in-vehicle information system (IVIS) was used to videotape drivers (N = 61) without their knowledge while driving 22 miles in normal traffic. The drivers were told that they were participating in a study of direction following and map reading. Two data-coding procedures were used to analyze videotapes. Safety-related behaviors were counted during consecutive 15-s intervals of a driving trial, and the occurrence of certain safety-related behaviors was assessed under critical conditions. These two methods of data coding were assessed for practicality, reliability, and sensitivity. Interobserver agreement for the five different driving behaviors ranged from 85% to 95%. Within-subject variability in safe driving was more pronounced among younger drivers and decreased as a function of age. Contrary to previous research that has relied on self-reports, driver risk taking did not vary significantly as a function of gender. These results are used to illustrate the capabilities of the technology introduced here to design and evaluate behavior-analytic interventions to increase safe driving. 相似文献

Community-based participatory research (CBPR) is increasingly being used to better understand and improve the health of diverse communities. A key strength of this research orientation is its adaptability to community contexts and characteristics. To date, however, few studies explicitly discuss adaptations made to CBPR principles and processes in response to community context and partners’ needs. Using data from our CBPR study, the San Francisco Chinatown Restaurant Worker Health and Safety Project, and drawing from literature on immigrant political incorporation, we examine the links between the contexts of the Chinese immigrant worker community, adaptations made by our collaborative, and study outcomes. In particular, we explore the concepts of contexts of reception and participatory starting points, which may be especially relevant for partnerships with immigrant communities whose members have historically had lower rates of civic and political participation in the US. We discuss contextual findings such as worker partner accounts of language barriers, economic and social marginalization, and civic skills and participation, as well as subsequent adaptations made by the partnership. We also describe the relative effectiveness of these adaptations in yielding equitable participation and building partners’ capacity. We conclude by sharing lessons learned and their implications for CBPR and partnerships with immigrant communities more broadly. 相似文献

The authors studied effects of healthy aging on 3 components of the internal force vector during static prehensile tasks. Young and older subjects held an instrumented handle using a 5-digit prismatic grasp under different digit configurations and external torques. Across digit configurations, older subjects showed larger internal normal (grip) and tangential (load-resisting) digit force components and larger internal moment of force. In contrast to earlier reports, safety margin values were not higher in the older subjects. The results show that the increased grip force in older persons is a specific example of a more general age-related problem reflected in the generation of large internal force vectors in prehensile tasks. It is possible that the higher internal forces increase the apparent stiffness of the hand+handle system and, hence, contribute to its stability. This strategy, however, may be maladaptive, energetically wasteful, and inefficient in ensuring safety of hand-held objects. 相似文献

This study investigated the extent to which the psychological conditions and job characteristics predicted work engagement amongst higher education employees (n?=?149, females?=?60%) from a South African University. The participants completed a variety of instruments on psychological conditions of work, job characteristics and work engagement viz; the Work Engagement Scale (WES), Psychological Meaningfulness Scale (PMS), Job Enrichment Scale (JES), Work-Role Fit Scale (W-RFS), Co-Worker Relations Scale (C-WRS), Psychological Availability Scale (PAS), Self-Consciousness Scale (SCS), Job Resources Scale (JRS), Outside Activities Scale (OAS), Psychological Safety Scale (PSS), Supervisory Relations Scale (SRS) and the Co-Worker Norms Scale (CWNS). Data analysis applied multiple regression to predict work engagement from psychological meaningfulness, psychological availability and job characteristics and also to determine the mediation effect of psychological condition of availability on the relationship between work engagement and job characteristics (resources). Findings suggest psychological meaningfulness to predict work engagement and to mediate the relationship between job characteristics and work engagement. Psychological resources for work engagement should emphasise a sense of meaningfulness as a resource for work participation. 相似文献

The functional assessment of challenging behavior (e.g., self-injurious behavior) has evolved over many years of research and practice. This concise review summarizes the positive predictive value, negative predictive value, accuracy, sensitivity, and specificity of common procedural adaptations reported to improve functional assessment safety and efficiency. We conclude with suggestions for clinicians and researchers. 相似文献

Double Reference Points: the Effects of Social and Financial Reference Points on Decisions Under Risk 下载免费PDF全文
The existing literature is inconsistent about how social comparison affects risk attitudes. We propose a framework where the total utility is composed of the social and financial utilities. The financial utility is consistent with prospect theory (i.e., an S‐shaped utility function with a financial reference point), whereas the social utility is affected by both social and financial reference points. Therefore, social risk attitudes are determined by interaction between gains/losses in both social and financial contexts. On the basis of safety‐first principle, we propose that when experiencing financial gains, individuals tend to seek upside potential and take social risks (i.e., a convex social utility function). In contrast, when facing financial losses, people would be more risk seeking in social gains but more risk averse in social losses to maximize security (i.e., an inverse S‐shaped utility function). We also propose that the relative importance of financial and social utilities depends on the saliency of the reference points and size of stakes. Studies 1 and 2 showed that individuals were risk seeking in both social gains and losses with social reference points alone. Studies 3 and 4 demonstrated that when both financial and social reference points were salient, participants were risk averse in both social gains and losses when facing financial gains, but risk seeking in social gains and risk averse in social losses when facing financial losses. The hypotheses derived from the theoretical framework were in general supported by our experiments. Copyright © 2015 John Wiley & Sons, Ltd. 相似文献

‘I Can't Go Back Because If I Go Back I Would Die’: How Asylum Seekers Manage Talk about Returning Home by Highlighting the Importance of Safety 下载免费PDF全文

Asylum seekers living in the UK have been shown to have fled danger in their countries of origin, only to face hardship and the threat of deportation once there. This paper draws on the discursive psychological approach to address the way in which asylum seekers in the UK manage questions about returning to their country of origin. Interviews were conducted with nine asylum seekers in a refugee support centre in the Midlands. The interviews were transcribed and analysed using discourse analysis. The analysis showed that participants drew on the notion of safety to counter suggestions that they should return to their country of origin and to manage their identity as legitimate asylum seekers in need of support. The use of this strategy and the use of interviews for discursive analysis are discussed. Copyright © 2014 John Wiley & Sons, Ltd. 相似文献
