Which constructs can predict emotional exhaustion in a working population? A study into its determinants

The main objective of this study was to examine the psychosocial stress model developed by Taylor and Aspinwall with emotional exhaustion as the outcome variable. Respondents, 409 men and 346 women, who had a paid job for at least 20 hours per week, completed questionnaires concerning demographic variables, personality, temperament, work pressure, workload, perceived social support, appraisal, coping, and emotional exhaustion. Structural equation analyses provided only partial support for the validity of the model. First, on theoretical and statistical grounds, one more path linking external resources to social support was added. Second, contrary to expectations, coping styles did not predict emotional exhaustion. To conclude, when coping is measured retrospectively, it does not add to our understanding of emotional exhaustion. It is suggested that future studies should be longitudinal and include objective measures of stressors and psychosocial health outcomes in addition to self‐reports.

When work strain transcends psychological boundaries: an inquiry into the relationship between time pressure,irritation, work–family conflict and psychosomatic complaints

Against the theoretical background of the effort–recovery model and the action regulation theory, the author presents a cross‐sectional questionnaire study testing hypotheses about the relationship between work‐related time pressure, cognitive and emotional irritation, work–family conflict and psychosomatic complaints. Subjects were 576 female home care nurses. Results of a path analysis show that the relation of time pressure and psychosomatic complaints is partially mediated by experiencing a work–family conflict; also the relation of time pressure and work–family conflict is partially mediated by cognitive and emotional irritation. It is argued that cognitive and emotional irritation are fruitful concepts for a more comprehensive understanding of the relationship between work stressors and the development of strain‐based work–family conflict. Implications for the prevention of work–family conflict are outlined. Copyright © 2008 John Wiley & Sons, Ltd.

Occupational injury and illness in the semiconductor manufacturing industry

Two thousand nine hundred and ninety-four reports of OSHA-reportable occupational injury or illness cases in 1984 from member companies of a national trade association of semiconductor manufacturing firms were analyzed. The 37 participating manufacturing facilities represented 16 companies employing over 95,000 persons, or approximately one-third of the U.S. work force for this industry in 1984. The annual incidence rate for all reportable injuries and illnesses was 2.7 per 100 full-time employees (FTE) for men and 3.7 per 100 FTE for women. Strains, sprains, or dislocations were the most frequently reported incidents (N = 956 [31.9%]), followed by cuts, lacerations, punctures, scratches, and abrasions (N = 445 [14.9%]), and chemical burns (N = 401 [13.4%]). Increased work-loss days per case were associated with manufacturing sites that did not have an employee health clinic on the premises, with custodial occupations, and with female gender.     

长期居住海平面后藏族经受急性减压低氧时的体力活动能力

本研究从急性低氧对移居海平面后藏族的体力活动能力的影响来探索藏族的高原低氧适应机制。结果揭示藏族的最大体力负荷强度没有显著下降，最大氧耗和氧脉搏也没有明显变化，动脉血氧饱和度明显高于汉族，这更显示藏族对高原低氧适应机制有独特之处。推测可能是藏族在氧的摄取、传递和释放过程比汉族更有利于对高原低氧环境的适应。     

Are Continuity Clinic Patients Less Satisfied When the Resident Is Postcall?

Due to recent public debate and newly imposed resident work hour restrictions, we decided to investigate the relationship of resident call status to their ambulatory patients' satisfaction. Resident continuity clinic patients were asked to rate their level of satisfaction on a 10-point Likert-type scale. Using multiple regression approaches, these data were then assessed as a function of resident call status. We found that in 646 patient encounters, patient satisfaction scores were significantly less when the resident was postcall, 8.99 ± 1.8, than when not postcall, 9.31 ± 1.3. We herein discuss etiologies and implications of these findings for both patient care and medical education.

轻度贫血对学龄儿童体力工作能力的影响

本文报告29对轻度贫血和非贫血儿童在平板机运动试验条件下的最大运动耐受时间,耗氧量、心率和运动后血乳酸浓度。结果表明,轻度贫血组儿童最大耐受时间、最大耗氧量均低于非贫血组。运动后血乳酸高于非贫血组。经一个月补铁治疗后,贫血组最大耐受时间提高0.9分钟,血乳酸降至非贫血组水平,但最大耗氧量无显著性变化。由此说明轻度贫血对学龄儿童体力工作能力有一定的影响。     

平板玻璃厂工人体力劳动强度的调查

本文对平板玻璃厂工人体力劳动强度的调查结果表明,该厂9个工种的平均劳动时间率为58%(18～83%);8小时工作日平均耗能为7010kJ/man(4043～9190)。在所调查的9个工种中,劳动强度属Ⅰ级占33.3%,Ⅱ级占44.4%,Ⅲ级占22.3%。与其它玻璃制品行业比较,平板玻璃厂主要特点是劳动耗能量大,工时利用率低。为此,建议今后应改进生产工艺与劳动条件,合理劳动定额、定员,提高工时利用率,降低体力劳动强度。
