Job stressors and the pursuit of sport activities: A day-level perspective.

This article addresses the relation between day-specific experiences of job stressors and the pursuit of off-job activities. Following the limited-resources model of self-regulation, the authors proposed that job stressors and long working hours are negatively related to pursuit of sport activities after work because, after stressful days, employees have no resources left for initiating and persisting in effortful behaviors such as sport. Routines for off-job activities were hypothesized to be positively related to the pursuit of sport activities after work. Seventy-eight police employees completed a daily survey over 5 working days and indicated that they perceive sport to be highly useful for recovery. Random coefficient modeling showed that job stressors (particularly situational constraints) encountered on a specific day were negatively related to self-regulatory resources and to the amount of time spent on sport activities after work, whereas the relation with low-effort activities was positive. Thus, after a stressful day when an effective recovery activity such as sport is highly needed, persons tend to engage less in such an activity.

The association of distress and sleeping problems with physicians’ intentions to change profession: The moderating effect of job control.

The present study examined whether job control moderated the association between stress indicators (distress and sleeping problems) and intentions to change profession among 2,650 Finnish physicians. Ordinal logistic regression analysis was applied. The authors found that high levels of distress and sleeping problems were associated with higher levels of intentions to change profession, whereas high job control was associated with lower levels of intentions to change profession even after adjusting for the effects of gender, age, and employment sector. In addition, high job control was able to mitigate the positive association that distress and sleeping problems had with intentions to change profession. Our findings highlight the importance of offering more job control to physicians to prevent unnecessary physician turnover. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

动态环境下工作分析定性模拟方法研究

传统工作分析方法的工作环境静态假设与企业实际面临的动态环境现实相违背,使得其工作分析结果缺乏动态适应性,可以采用定性模拟的方法对原有的分析结果进行修正.首先设计了工作分析的定性因果关系模型、变量知识的定性表述方法、状态变量转换规则及模拟步骤;为防止模拟组合爆炸,设计了基于管理常识的过滤器;最后给出了企业管理岗位职能变化过程的模拟应用实例,模拟结果符合企业管理相关理论.

能耗受限时实现性能最大化的作业管理模型

在诸如星载并行计算机这样的系统中,一定周期内,系统能耗存在上限。围绕高产出率计算的概念,针对这种能耗受限条件下性能最大化的作业管理需求,提出了一种作业分配的模型。该模型基于计算节点、作业的性能和能耗参数,动态地进行作业分配,从而在满足能耗上限的前提下获得尽可能大的计算性能。通过模拟实验,验证了该算法的有效性。     

油基钻井液下水泥浆抗污剂的研究与应用

针对目前油基钻井液下水泥浆易被污染,固井质量难以保证的问题,运用实验方法结合理论分析,开展了抗污染水泥浆体系的研究。利用人工岩心法证实了油基钻井液对固井质量有较大影响,特别是对二界面胶结强度影响最大。通过实验分析了基础水泥浆被油基钻井液污染后性能的变化,研制出了一种主要成分为烷基酚聚氧乙烯醚的抗污染剂Anti-P。室内实验结果表明,将1%抗污剂Anti-P加入水泥浆中,在水泥浆被少量油基钻井液污染后（小于10%）,水泥浆性能不受影响,保证了固井质量。将其在多口井进行应用,效果良好。该成果填补了目前抗污染水泥浆体系的空白,值得进一步研究推广。      

The effect of self-reported and observed job conditions on depression and anxiety symptoms: A comparison of theoretical models.

The demand/control/support and effort/reward imbalance models have relied on self-reported methods to describe how poor psychosocial working conditions lead to harmful health outcomes. The hindrance/utilization model uses an observational methodology to assess these relationships. Cross-sectional observational and self-reported data from 98 civil servants participating in the Whitehall II Study of British civil servants were used to test whether work conditions measured by each of the three theoretical models explained a significant amount of the variance in depression and anxiety symptoms. Observational measures were also used to assess potential common methods variance bias between the self-reported job conditions and the outcomes. Results showed that the demand/control/support model explained the most variance in depression and anxiety symptoms and the associations were not wholly due to common methods variance. Moreover, measures associated with job resources (e.g., skill discretion, social support and skill utilization) had a protective effect on depression and anxiety symptoms. Exertion-related conditions (e.g., demands, effort, over commitment) were not consistently associated with depression or anxiety symptoms.
