学习型团队三维特征结构与团队效能关系的现场实验研究 总被引:11,自引:0,他引:11
本研究用现场实验的方法对作者提出的学习型团队三维特征结构与团队效能关系模型进行了实证研究。结果表明:学习型团队三维特征结构可以显著地影响团队效能。实验组在团队学习、团队角色、团队授权三维水平上与对照组相比均有非常显著的差异,在质量合格率上明显好于对照组。改善团队学习、团队角色、团队授权三维水平对提高我国现阶段企业的组织效率有重要价值。 相似文献

Few empirical studies have been conducted to determine the influence of hospitalization on adolescents' psychosocial processes because younger children are regarded as more vulnerable. Therefore, the purpose of this self-report, retrospective study of 115 adolescents was to compare the self-esteem and locus of control of the never hospitalized to that of adolescents hospitalized during adolescence, prior to adolescence, and during and prior to adolescence. Although no significant differences were found, the findings raise questions about long-term effects of early experiences, especially among lower socioeconomic status youth. Also, general measures of self-esteem and locus of control may be unable to determine situation-specific effects. 相似文献

Modernist approaches to research in the social sciences dominate academia, including much of organization science. Discovery through reason, observation, and analysis are the quintessential modernist quests. However, this reductionist approach to essentialize the social through the usage of language, a product of culture with its inevitable entanglement with cultural ideology, values, sensibility, intelligibility, and history, is akin to capturing a moving target on shifting grounds. Positing social constructionism as an alternative, we explain it has revolutionalized the social sciences and organization science alike; offer an array of social constructionist inquiry methodologies to fuel generative possibilities for organization research; compare and contrast modernist and social constructionist organization theories, research methodologies and assumptive metaphors to accentuate the textual and dialogic potential social constructionism brings to organization science; and conclude with creative ways social constructionism can realize actionable knowledge through co-creation among communities. 相似文献

This study aimed to explore the physiological and psychological impacts on male medical interns during on-call duty (OCD). A prospective study of 13 medical interns was carried out using repeated testing during an on-call internal medicine and a duty-free course. There are 10 OCDs per month and each duty is composed of 33.5 consecutive work hours followed by 2 duty-free days for a time period of 3 months. Spectral analysis of R-R intervals was performed to evaluate the participants' heart rate variability. Among the three main spectral components distinguished, a high-frequency (HF) component of 0.15-0.4 Hz and a low-frequency component (LF) of 0.04-0.15 Hz were analyzed. The ratio of LF and HF (LF/HF) was also calculated. Reduced LF/HF, which suggests reduced cardiac sympathetic modulation, was found during duty night work. Increased HF was identified during the first sleep after OCD, which corresponded to the sleepiness scales. The OCD causes temporary emotional influence by the findings of higher anxiety and depression scores. In addition, inattention and impulsiveness, as represented by the continuous performance test score and lower nocturnal sympathetic modulation, were found, which indicated the differences between the internal medicine course and duty-free course. Our study suggests that 10 stressful on-call duties monthly result in reduced sympathetic modulation during duty night work, high anxiety and depression state, and a persistent inattention. 相似文献
