This paper investigates the relationship between defensive communication in performance appraisal settings by considering the mediating effect of leader–member exchange relationships. In a study of employees of a US federal fire department, defensive communication was associated with lower quality leader–member exchange relationships, which in turn was related to burnout. We discuss the implications of these findings, particularly as they apply to organizations and their employees, as well as limitations and directions for future research. 相似文献

观察了烟雾吸入后大鼠细胞内、外肺表面活性物质(PS)含量的变化及可能机理.分别检测了正常对照及烟雾致伤大鼠伤后2、6、12和24h的动脉血气、肺水量、血浆内皮素-1(ET-1)含量、支气管肺泡灌洗液(BALF)和肺匀浆总磷脂(TPL)含量、肺组织内板层体(LB)表达及肺泡Ⅱ型上皮细胞内LB平均数等.结果发现:动物伤后出现急性呼吸衰竭和严重肺水肿;血浆ET-1和BALF中TPL进行性升高,二者相关显著;肺组织和全肺TPL显著降低,LB表达及LB平均数明显减少,且与肺组织TPL的变化明显相关.提示烟雾吸入伤早期肺泡腔中细胞外PS增加,ET-1在介导PS持续分泌中可能有重要作用;细胞内及全肺PS减少,除分泌亢进外,可能还有合成障碍和(或)降解增加 相似文献
