固井水泥作业场所粉尘治理及效果评价

对油田固井水泥生产和使用作业场所进行了劳动卫生学调查,对粉尘污染严重的立式散装水泥储存罐尾气口排放、水泥裸口装卸、水泥与外加剂干混工艺进行了技术改造和粉尘治理,使作业场所空气中粉尘浓度由平均49.94 mg/m3降至1.19 mg/m3,除尘效率达97.81%,效果明显。     

A multilevel model of emotional skills,communication performance,and task performance in teams

There is increasing research regarding the influence of emotions on teamwork. In this study, we use a multilevel approach to examine how team members' use of emotion‐related skills affects team task performance and communication performance within the team. We measured individual self‐reported emotional skills prior to team formation and then collected peer‐rated individual communication performance and independently rated team task performance eight weeks later. Although there was no influence at the individual level between emotional skills and performance, team‐level emotional skills positively predicted team task performance scores. At the cross level, team‐level emotional skills predicted individual‐level communication performance. These findings emphasize the importance of distinct team emotional skills in shaping both team performance and individual team member performance. Copyright © 2011 John Wiley & Sons, Ltd.

An interpersonal perspective of perceived stress: Examining the prosocial coping response patterns of stressed managers

We adopt an interpersonal perspective and examine the adaptive effects of managers' perceived stress on their behavior towards subordinates. Drawing from the transactional model of stress (Lazarus & Folkman, 1984), we advance a model that highlights the propensity for stressed managers to engage in prosocial coping behaviors towards their employees, which in turn are related to lower levels of turnover and higher levels of job performance. We tested our predictions in a sample of 281 employees and their 53 managers working in a clothing retailer in Turkey. Consistent with predictions, we found positive effects of managers' perceived stress on their prosocial coping behaviors and employee outcomes. Managers' perceived stress was positively related to sharing credit with employees for managers who held positive implicit prototypes about employees. Results also indicated that managers' perceived stress was positively related to sharing knowledge with their subordinates regardless of implicit follower prototypes. Both sharing credit and sharing knowledge, in turn, were related to turnover intentions and actual turnover, and sharing credit was related to job performance. This study extends past work by adopting an interpersonal perspective of stress and demonstrating that managerial stress can have positive effects on employee outcomes via prosocial coping behaviors.     

高职院校学生职业能力培养研究的意义

虽然教育部在中等职业教育的培养目标中就提出了“综合职业能力”这个概念,且各类职业学校对如何培养学生综合职业能力也做了一些探索,但由于综合职业能力培养毕竟是近几年世界职教界研究的新课题,对我国职业教育实践来说更是全新的理论,因而对其进行研究具有理论和实践上的意义.参7.
