城市消防安全影响因素及评估体系研究——以海南某沿海城市为例

在前人评估重点研究公共消防基础、灭火救援力量的基础上,增加消防安全形势、火灾防控工作对城市消防安全影响因素的研究,以海南某沿海城市为例,采用层次分析法构建城市消防安全评估体系,设置定量化评分判定基准,运用模糊集值统计法计算得分。评估结果表明体系更真实地反映了该市消防安全现状及火灾防控薄弱环节,最后针对高风险项提出具体改进措施。该体系模型丰富了评估指标数量;宏观考虑了该市热带气候、旅游型城市特征、火灾情况对消防安全形势的影响;更重要的是,提出将社会面火灾防控工作纳入评估体系。研究对于城市消防安全评估的宏观化、系统化、地域化、实用化、定量化都有一定参考意义。     

Antecedents and consequences of satisfaction with work–family balance: A moderating role of perceived insider status

This study developed a moderated mediation model to investigate how family‐supportive paid leave and supervision affect employees' satisfaction with work–family balance and in turn their affective organizational commitment and supervisor‐directed organizational citizenship behavior depending on their perceived insider status in the organization. Our analysis of data collected from 118 employee–supervisor dyads in Korean organizations revealed that satisfaction with work–family balance mediated the linkages from family‐supportive supervision to affective organizational commitment and supervisor‐directed organizational citizenship behavior, and the linkage from family‐supportive paid leave to affective organizational commitment. Results further showed that the entire mediational process for family‐supportive supervision was more pronounced for those who perceived themselves to be an insider of their organizations, while the same pattern was not found for the meditational process related to family‐supportive paid leave. Our findings provide theoretical implications for work–family balance research and offer practical suggestions to make employees satisfied with work–family balance.     

Infrared thermography reveals effect of working posture on skin temperature in office workers

Introduction. Musculoskeletal symptoms related to using traditional computer workstations are common. Quantitative methods for measuring muscle stress and strain are needed to improve ergonomics of workstations. We hypothesize that infrared thermography (IRT) is suited for this purpose. Methods. This hypothesis was evaluated by estimating muscle activity in upright and traditional working postures with IRT and surface electromyography (sEMG). IRT and sEMG measurements were conducted in 14 female participants with both working postures. First, measurements with the traditional posture were performed. Later, participants had 1?month to adjust to the upright working posture before repeating the measurements. IRT images were acquired before and after a full working day, with sEMG recordings being conducted throughout the measurement days. Participants evaluated their neck pain severity using neck disability index (NDI) questionnaires before the first and after the second measurement day. Results. Spatial variation in upper back temperature was higher (p?=?0.008) when working in traditional posture and the upright working posture reduced (p?p?=?0.003) after working in the upright posture. Conclusion. IRT was found suitable for evaluating muscle activity and upright working posture to reduce the NDI and muscle activity in the upper back.     

Simultaneous effect of shift work on blood pressure and lipid profile: a path analysis

The aim of this study was to assess the direct and indirect effects of shift work (SW) on the systolic blood pressure (SBP) and lipid profile of male workers. For this purpose, a cross-sectional study was conducted involving 6539 male workers of Esfahan Mobarakeh Steel Company. From all of the participants, 3065 (46.8%) were day workers and the remainder were shift workers. The results of path analysis revealed that the most effective variables on SBP were body mass index, fasting blood sugar, triglycerides and SW with a total effect of 0.241, 0.095, 0.064 and 0.056, respectively.     

Effects of safety climate on safety norm violations: exploring the mediating role of attitudinal ambivalence toward personal protective equipment

Problem

Research on the role of organizational and psychosocial factors in influencing risk behaviors and the likelihood of injury at work showed that safety climate also has great impact on workers’ behavior. However, the mechanisms through which this impact operates are still partially unclear.

Method

In order to explore the role that attitudinal ambivalence toward wearing PPE might play in mediating the impact of safety climate on safety norm violations, a questionnaire was administered to 345 Italian workers.

Results

Three dimensions of safety climate (i.e., company safety concern, senior managers’ safety concern, supervisors’ attitudes towards safety) were found to be positively associated with the individual ambivalence level, whereas the fourth one (i.e., work pressure) was negatively correlated with it. In turn, low levels of ambivalence were associated with a lower tendency to break the safety norms, even though the perception of a good safety climate also maintained a direct effect on unsafe behaviors.

Impact on industry

Designers of training program for the prevention of work related injuries must pay great attention to the psycho-social factors (such as the effects of the safety climate perception by employees on their attitudes and behaviors), and include specific contents into the prevention programs in order to improve workers compliance with safety norms.

Stressful but rewarding: Norwegian personnel mobilised for the 2004 tsunami disaster

Adequate responses to disasters and emergency situations rely, among other factors, on coping abilities in disaster workers and emergency personnel. In this study, different aspects of disaster-related stressors and training/experience were investigated in Norwegian personnel (n = 581) mobilised for the 2004 tsunami disaster. The level of stress reactions, measured nine to ten months after the tsunami, was relatively low in this sample, indicating that the personnel coped well with the challenges of the disaster. The level of intrusive memories was higher in disaster-area personnel (n = 335) than in home-base personnel (n = 246). Stress reactions were significantly associated with witnessing experiences (disaster-area group) and with having to reject victims in need of help (both groups). Specific preparation for the mission was associated with a lower level of stress reactions in disaster-area personnel. Such factors may be considered in training and preparation programmes for disaster workers.     

安全生产责任的制度整合与伦理道德建设

在分析安全生产责任危机含义和安全生产责任概念基础上,指明安全生产责任体系的"四要素",即道德责任、政治责任、法律责任与管理责任,重点阐明道德责任是该体系的基础要素及其意义。根据对我国现有安全生产责任制度的分析,提出一个关于安全生产责任制度建设的伦理框架:强化安全生产责任意识;用人权伦理原则对安全生产责任制度伦理化;以特定的安全生产责任的伦理规范和准则构建责任规则系统;强化责任主体道德素质培养与监察制度建设,促使其自觉履行好自身应负的安全生产责任。总之,该理论框架为安全生产责任制度建立提供一个新的伦理学基础。

安全生产效益的分析评价及其与安全投入的关系

通过把握和界定安全效益、安全投入等反映安全生产的经济活动特征和规律的经济学范畴的内涵,指出从企业的经营利润指标上看安全投入不能带来直接经济效益,只产生远期(长远)的、潜在的间接性效益,包括间接经济效益和非经济效益,安全投入的效益具有间接性、潜在性、隐形性、不确定性和迟滞性。由于生产安全事故风险不可能为零,当事故预防水平达到一定程度(可接受的程度及其以下)时,通过增加经济投入提高预防水平而对于事故风险的削减无明显的效果,就应考虑与经济效益的结合问题。笔者提出安全投入数量限度问题和安全投入的阈值;并进一步建立安全效益评价模型和安全投入与安全指标的函数关系模型,对安全投入与安全水平(安全指标)、安全效益的关联关系进行了定性分析。
