施工现场的风险管理应用研究

风险管理理论已广泛应用于项目的设计、采购及施工等各个阶段。在建设项目施工阶段的应用,特别是在施工事故的主动预防领域的应用,国外企业已取得不少成效。通常建设项目的施工现场由一系列的土建、安装、试验等施工活动组成,每一项施工活动又分解为不同的施工步骤,各施工步骤之间又存在多种工艺关系或组织关系,结合这些关系的特点,如果能对每一步骤中存在的危害进行识别、评价并根据评价结果采取相应的控制措施,则整项施工活动的风险可以从"源"上消除或降低到可接受程度,从而实现安全。针对施工现场施工活动多样、人员流动性大等特点,通过对施工现场的风险管理的应用研究,以期为各级从事现场的管理技术人员提供一种便于现场进行施工风险控制的实践方法。     

我国安全生产法制宣传现状调研与对策研究

在调研我国当前安全生产法制宣传现状、存在问题以及地方安监部门和生产经营单位的现实需求等的基础上,本研究提出今后一段时期内提高我国安全生产法制宣传效果的建议措施,包括研究建立安全生产法制宣传制度、明确有关工作机制,优化安全生产网络与信息系统等平台、充分利用现代化传媒手段进行宣传,进一步发挥教育培训作为安全生产法制宣传的载体作用,以及加强生产经营单位重点人群、职业健康领域和标准的法制宣传。     

我国“十二五”期间生产安全死亡事故直接经济损失估算

对“十二五”期间发生的、已经公布的生产安全死亡事故报告进行检索,选择事故调查报告要素比较齐全、具有代表性的生产安全死亡事故219起进行直接经济损失统计分析,计算每死亡1个人造成的直接经济损失。建立以事故死亡人数测算全国生产安全死亡事故直接经济损失的计算模型,根据公开的年度生产安全事故死亡人数,估算全国年度生产安全事故直接经济损失。估算结果表明,“十二五”期间我国生产安全死亡事故直接经济损失达到4 651亿元,约占国内生产总值的0.16%,占全国财政收入的0.72%,生产安全死亡事故的直接经济损失巨大。     

安全生产大数据的5W2H采集法及其模式研究

为从安全生产大数据中挖掘安全规律并最终提炼安全生产基础原理,首先在对安全生产大数据的定义及其内涵进一步阐释基础上,提出安全生产大数据采集的定义,并将其分解为3个过程;然后提出安全生产大数据的5W2H采集法,并对其内涵(采集原因,使用主体、采集者及采集对象,采集数据类型,采集边界,采集时间,采集数据量及其采集方法）进行详细分析;最后以思维路径为主、过程路径和技术路径为辅,建立安全生产大数据采集的一般模式。结果表明,安全生产大数据采集模式的研究可为安全生产大数据的存储、处理及其应用提供基础。     

芳纶1313纤维的特点及其在个体防护服装领域的应用

对芳纶1313纤维的发展历程、性能特点、生产加工、产品应用等各个方面进行了详细的阐述。芳纶1313纤维是一种性能优异的阻燃耐热纤维,在安全生产领域有着广阔的应用前景。自问世以来历经半个多世纪的发展,其在安全生产领域的应用价值已经得到广泛的认可。由于芳纶1313纤维具备一系列的突出优点,同时也存在某些缺陷,因此建议扬长避短,充分发挥这种纤维的种种优点,同时通过纤维改性、改进和优化生产工艺等方法,充分发挥其在安全生产领域的应用,使之产生应有的社会效益和经济效益。     

Experimental evidence for the effects of task repetitiveness on mental strain and objective work performance

People frequently have to work in high repetitive jobs. Previous research has focused exclusively on the effects of task repetitiveness on well‐being, while neglecting effects on work performance. In the present study, we aimed to fill this void by conducting two workplace simulations with experimental manipulations of task repetitiveness. Participants worked for about 5 hours at either a computer workstation, compiling computer hardware packages according to customer requests (Experiment 1, N = 160), or at an assembly line, piecing together equipment sets for furniture (Experiment 2, N = 213). Both experiments provide consistent evidence that high repetitiveness has a detrimental effect on well‐being, whereas work performance increases under conditions of high repetitiveness. On a practical level, our study hence shows that high task repetitiveness is a double‐edged sword for both employees and organizations. On a conceptual level, our findings emphasize the necessity to account for both mental strain and work performance when examining the effects of task repetitiveness.

Episodic envy and counterproductive work behaviors: Is more justice always good?

The authors examined how perceived event‐specific procedural and distributive justice about own and envied others' outcomes interacts with episodic envy to predict counterproductive work behaviors. Our results were consistent with the attribution model of justice, finding that episodic envy significantly predicted counterproductive work behaviors aimed at envied others in the workplace and that this relationship was more pronounced when perceptions of procedural, but not distributive, justice about own or envied others' outcomes were high rather than low. We tested a moderated‐mediation model in which self‐attributions for the outcome mediated the effect of episodic envy on counterproductive work behaviors and that the effect of envy was stronger when perceptions of own or others' procedural justice were high rather than low. This research contributes to the literature on envy processes in the workplace and is the first to use a specific emotion, envy, as a proxy for a negative outcome in a demonstration of the attribution model of justice.

Family–work conflict and job performance: A diary study of boundary conditions and mechanisms

In this study, we used a within‐person daily research paradigm to examine the relationship between daily family–work conflict (FWC) and daily job performance. On the basis of theory on dynamic behavior, we hypothesized that concentration serves as a mechanism through which daily FWC impairs daily job performance. We further predicted that psychological detachment from work during time‐off (i.e., mentally switching off) buffers the negative relationship between daily FWC and daily job performance. Ninety‐five employees completed daily surveys over one workweek. Multilevel modeling results showed that daily FWC was negatively associated with daily job performance and that concentration mediated this relationship. Furthermore, general psychological detachment, but not daily psychological detachment, buffered the negative relationship between daily FWC and daily job performance. The current findings suggest that daily FWC has negative performance implications and that the general level rather than the daily level of psychological detachment from work helps alleviate the negative implications.
