慢性应激对大鼠行为和免疫细胞热休克蛋白70表达的影响

目的：研究慢性不确定应激对大鼠急性整体热水浴后外周血和脾脏免疫细胞热休克蛋白70（Heat shock protein 70, HSP70）表达的影响。方法：随机将大鼠分成慢性应激组和控制组（每组14只）。通过4周的慢性不确定性应激诱发实验组大鼠明显的抑郁行为,此期间控制组大鼠正常饲养。随后给予大鼠42度整体热水浴刺激,维持直肠温度41度25min。热刺激后6h,采用流式细胞仪测定大鼠外周血和脾脏免疫细胞HSP70 水平。结果：与控制组大鼠相比,慢性应激大鼠在急性热刺激后HSP70合成明显减少。控制组大鼠的所有被检测的免疫细胞热应激后HSP70合成均明显增加。相反,慢性应激大鼠仅在外周血的单核细胞和粒细胞检测到HSP70合成增加,同时升高的水平明显低于控制组大鼠。结论：慢性应激降低大鼠免疫细胞HSP70的热诱导反应,提示HSP70保护性作用减弱可能参与了慢性应激损害免疫细胞功能的生物学过程     

Cohesiveness, coach's interpersonal style and psychological needs: Their effects on self-determination and athletes' subjective well-being

GoalThe goal of this study was to test the impact of cohesiveness and coaches' controlling interpersonal style on athletes' perceptions of autonomy, competence and relatedness. A contextual motivation sequence [Vallerand, R. J. (1997). Toward a hierarchical model of intrinsic and extrinsic motivation. In M. Zanna (Ed.), Advances in experimental social psychology, Vol. 29 (pp. 271–360). New York: Academic Press.] was tested whereby social factors supporting the satisfaction of basic needs would increase the level of sport self-determination, which in turn, should predict subjective well-being in athletes.MethodThe proposed sequence was tested with 197 basketball players using structural equation modeling. The hypothesized model was supported.ResultsPerceptions of cohesiveness positively predicted the satisfaction of the basic needs. Perceptions of coaches' controlling interpersonal style negatively impacted feelings of autonomy. In turn, psychological needs predicted self-determination in sports ensuing greater sport satisfaction and positive emotions in sports. Tests of indirect effects also supported the mediating role of psychological needs and self-determination.ConclusionResults are discussed in light of the different types of motivational antecedents and their influence on the psychological needs.

国家青年排球队员时间管理倾向与自我价值感的相关研究

运用时间管理倾向量表和自我价值感量表对13名国家青年排球队运动员的研究表明,国家青年排球队运动员的整体时间管理倾向与大学生没有显着差异;自我价值感显着高于常模群体,具有较高的自我价值感水平;相关分析发现,时间监控观与总体自我价值感和一般自我价值感之间的相关显着,时间监控观与社会取向的家庭自我价值感、时间管理倾向的三维度与个体自我价值感之间存在显着的相关;多重回归分析发现时间监控观对总体自我价值感和一般自我价值感具有直接的预测作用。     

A Method for Tracking Implementation Strategies: An Exemplar Implementing Measurement-Based Care in Community Behavioral Health Clinics

Implementation experts suggest tailoring strategies to the intended context may enhance outcomes. However, it remains unclear which strategies are best suited to address specific barriers to implementation, in part because few measurement methods exist that adhere to recommendations for reporting. In the context of a dynamic cluster randomized trial comparing a standardized to tailored approach to implementing measurement-based care (MBC), this study aimed to (a) describe a method for tracking implementation strategies, (b) demonstrate the method by tracking strategies generated by teams tasked with implementing MBC at their clinics in the tailored condition, and (c) conduct preliminary examinations of the relation between strategy use and implementation outcomes (i.e., self-reported fidelity to MBC). The method consisted of a coding form based on Proctor, Powell, and McMillen (2013) implementation strategy reporting guidelines and Powell et al.’s (2012) taxonomy to facilitate specification of the strategies. A trained research specialist coded digitally recorded implementation team meetings. The method allowed for the following characterization of strategy use. Each site generated 39 unique strategies across an average of six meetings in five months. There was little variability in the use of types of implementation strategies across sites with the following order of prevalence: quality management (50.00%), restructuring (16.53%), communication (15.68%), education (8.90%), planning (7.20%), and financing (1.69%). We identified a new category of strategies not captured by the existing taxonomy, labeled “communication.” There was no evidence that number of implementation strategies enacted was statistically significantly associated with changes in self-reported fidelity to MBC—however, financing strategies were associated with increased fidelity. This method has the capacity to yield rich data that will inform investigations into tailored implementation approaches.     

团队学习行为对团队有效性的影响

团队逐渐成为现代企业最基本的工作单元,团队学习水平决定着整个组织学习和适应的能力水平。研究一在杭州的6家企业的多个工作团队中,抽取400名员工,以半结构访谈和问卷调查为研究手段,对团队学习行为的理论结构进行探索性分析和验证性分析;研究二在对30多家企业101个工作团队中500多名员工进行问卷调查,进一步检验团队学习行为对团队绩效的影响效果。研究结果表明,企业中团队成员的学习行为包括两类,即互动性团队学习行为和反思性团队学习行为;互动性团队学习行为对团队有效性具有较好的预测效果,反思性团队学习仅对团队成员满意感具有较好的预测效果,对团队任务绩效则没有预测效果。     

Narrative Therapy Using a Reflecting Team: An Ethnographic Study of Therapists' Experiences

Narrative therapy in the last 15 years has been utilized by many clinicians and yet there is a lack of research on therapists' experience of this approach. This ethnographic research explores the views and perceptions of eight narrative therapists who belonged to a narrative team in an outpatient clinic. These therapists were observed and interviewed. Five themes emerge from the data. The themes include a sense of success in reducing the clients' problems as well as some limitations of narrative therapy. Two recommendations for research and practice involve the use of narrative therapy without a team and the use of narrative therapy in addressing issues of family violence.     

Effectiveness in top management group meetings: The role of goal clarity,focused communication,and learning behavior

Bang, H., Fuglesang, S. L., Ovesen, M. R. & Eilertsen, D. E. (2010). Effectiveness in top management group meetings: The role of goal clarity, focused communication, and learning behavior. Scandinavian Journal of Psychology, 51, 253–261. To explore the relationship between goal clarity, focused communication, learning behavior, and team effectiveness (i.e., task performance, relationship quality, and member satisfaction), self‐report and observer data from eight top management groups that processed 56 agenda items during meetings were analyzed. We found that goal clarity and focused communication was positively related to team effectiveness. The effect of goal clarity on team effectiveness was partially mediated by focused communication. Speaking up when a goal was unclear increased focused communication, task performance and relationship quality. Speaking up when the discussion was off track was not related to task performance and member satisfaction, and was negatively related to relationship quality. These findings have implications for how to conduct an effective management meeting.     

共享心智模型影响团队绩效的权变模型

共享心智模型指团队成员关于团队关键要素的共同的知识结构, 诸多研究表明其能有效提高团队运作效能。本研究从权变的角度入手, 以负责通讯网络监控与维护的106个高技术团队为分析对象, 探讨团队的共享心智模型与团队绩效的关系, 并揭示团队互依性作为权变因素对共享心智模型与团队绩效关系的调节效应。层次回归分析结果表明, 共享心智模型能显著预测团队绩效, 而团队互依性则负向调节两者之间的关系, 即在互依性程度较低的团队里, 共享心智模型才显著提高团队绩效。作者从共享心智模型的测量和权变因素的作用两个角度展开讨论, 并基于此提出了后续的研究方向。     

Application of The Assimilation Model in The Context of Family Therapy: A Case Study

In this case study the aim was to apply the APES (Assimilation of Problematic Experiences Scale) model to the analysis of the family therapeutic treatment process. This was done as a qualitative methodological triangulation in a case of the family of a 10-year old psychotic boy. The study suggests that assimilation model is suitable for many kinds of data in analyzing family therapeutic treatment processes, makes the change more comprehensible, and yields information about the effectiveness of experiential family therapy techniques.
