患者集中大医院就医的行为经济学分析

认为患者的行为心理因素是造成就医集中现象的重要原因,其中,关于参照点的选择是影响患者就医行为的重要因素,风险规避、损失厌恶、心理账户、敏感度递减等因素也是重要的影响因素.通过提高社区医院的力量、改革医疗保险的支付方式、对技术的理性追求等措施,可以缓解这一反常现象.     

Variation in coordination of a discrete multiarticular action as a function of skill level

The authors investigated coordination modes that emerged as a function of the interaction between skill level and task constraints in a multiarticular kicking action. Five skilled, 5 intermediate, and 5 novice participants attempted to satisfy specific height and accuracy constraints in kicking a ball over a barrier. Skilled and intermediate groups demonstrated a functional coordination mode involving less joint involvement at the proximal joints and greater joint involvement at distal joints, mimicking a chip-like action in soccer. Conversely, the novice group tended to produce larger ranges of motion throughout the kicking limb in a driving-like kicking action. Key differences were also found for task outcome scores, joint angle-angle relations, and ball-trajectory plots between the skilled and intermediate groups and the novice group. Findings from this study demonstrated that joint involvement during this discrete multiarticular action is a function of skill level and task constraints rather than a consequence of a global freezing-freeing strategy suggested in some previous research. The authors also highlight the merit of using a model of the acquisition of coordination in examining how coordination modes for multiarticular actions differ as a function of skill.     

雄性HSF1基因缺陷小鼠的行为改变

为研究HSF1基因缺陷小鼠的行为特征,探索HSF1基因在小鼠行为表现中的作用。选取6~7个月大雄性HSF1基因缺陷小鼠39只及野生型小鼠36只进行情绪性评分、旷场实验、高架十字迷宫实验、简易迷津实验、T-CAT实验、独木桥实验和悬挂实验以观察其情绪性唤醒水平、焦虑水平、探索行为、工作记忆能力和运动能力。结果表明HSF1基因缺陷小鼠的情绪唤醒水平和焦虑水平较低、探索行为减少、T-CAT中转换率较低,提示小鼠的情绪、探索动机和工作记忆受HSF1基因的调控     

工程决策中的伦理问题及其对策

工程决策中的伦理问题是工程伦理学中最重要的问题.尽管工程决策所要考虑的伦理因素常常已经以不同的形式作为工程师的职业道德的一部分,在工程师协会章程或伦理规范里得到表达,但是仅此对于建造好的工程无济于事.如果没有合理的决策机制和决策程序,单靠工程师个人的力量,这些表达出来的要求是难以贯彻的.所以,什么人做决策和按什么程序决策就十分重要.建立"工程伦理委员会",按照民主程序,经过充分讨论协商,是正确处理工程决策中的伦理问题,最终作出最佳决策的切实可行的途径.     

组织认同的基础理论、测量及相关变量

组织认同是个体源于组织成员身份的一种自我构念,它与组织认定、组织承诺等概念存在显著差异。文章阐述了组织认同基础理论的三种主要观点,对比了差异论、资源论和信息论的研究视角和相互关系。文章着重说明了组织认同的测量工具,分析了组织层面和个人层面的前因变量,以及组织认同对离职意愿等结果变量的影响。文章最后指出今后有必要对扩展定义、影响因素和国家文化差异等方面进行探讨     

Toward a Social Psychology of Culture and Globalization: Some Social Cognitive Consequences of Activating Two Cultures Simultaneously

Despite the increased attention given to cultural phenomena in social psychology, the field has neglected issues related to globalization's cultural impacts. Meanwhile, opinions in the debates over these issues are divided, polarized, and often motivated by political and ideological commitments. Globalization has brought symbols of diverse cultures together and provided ample opportunities for the simultaneous activation of two or more cultural representations. Using our research on the social cognitive consequences of activating two cultural representations simultaneously as an example, we argue for constructing a social psychology of globalization that offers nuanced understandings of people's psychological responses to globalization. Although simultaneous activation of cultural representations does not determine an individual's cultural identity, it enlarges the felt distinctions between different identity options and magnifies the effects of identity choice. Furthermore, in situations that emphasize appropriating intellectual resources from diverse cultures to foster creativity, simultaneous activation of cultural representations may facilitate creative performance.     

主观社会经济地位与心理幸福感的关系：创造力的中介和安全感的调节作用

为探讨主观社会经济地位对心理幸福感的影响,以及创造力的中介作用和安全感的调节作用,采用问卷法调查了556名18～60岁城市成年人的主观社会经济地位、安全感、创造力和心理幸福感。结果发现：(1)主观社会经济地位正向预测心理幸福感;(2)性格优势之创造力是主观社会经济地位与心理幸福感的中介变量;(3)安全感调节了中介过程的前半路径。只有当个体的安全感较高时,主观社会经济地位对创造力才存在显著的正向预测作用。结果表明,提升社会经济地位的同时,还需要提升个体的安全感,这样才能更好地促进创造力的发展,并进一步增加个体的心理幸福感。     

Replication and extension of the military family stress model: The after deployment adaptive parenting tools ADAPT4U study

The military family stress (MFS) model conceptualizes that wartime deployments and post-traumatic stress disorder (PTSD) symptoms are associated with couple, parenting, and child adjustment difficulties. The aim of this study was to replicate and extend the military family stress model by examining the associations among deployment length, PTSD symptoms, marital functioning, parenting practices, and child adjustment in a replication sample of both National Guard and Reserve (NG/R) as well as active-duty service member families. The MFS model is extended to test whether these relationships vary between mothers and fathers. The sample included 208 families enrolled in a randomized controlled trial of a parenting program for military families (94.4% of fathers and 21.6% of mothers were deployed). Replicating the MFS model, we specified parenting, marital quality, and child adjustment as latent variables and conducted multi-group structural equation models. Parenting practices were positively associated with marital quality and child adjustment. PTSD symptoms were negatively associated with marital quality. The indirect effect from PTSD symptoms to parenting practices through marital quality was marginally significant. The indirect effect from marital quality to child adjustment through parenting practices was significant. There were no significant gender differences between the two structural models. This study provides empirical support for the MFS model. Results demonstrate that deployment-related stressors are significantly associated with parent and family functioning. Parenting programs for military families might effectively target similar risk processes among both mothers and fathers.     

8—12岁超常与常态儿童的检测时比较

研究者采用两种视觉检测时任务,比较了8至12岁超常和常态儿童的检测时发展变化特点。结果发现：随着年龄的增长,超常组和常态组儿童的检测时都呈现出逐步减小的趋势,并且对于不同任务的检测时,两组儿童的发展速度不同,但均未表现出性别差异;在不同的年龄段和检测时任务中,超常组儿童的检测时均显著地快于常态组儿童。通过对两组儿童的检测时发展速率的比较还发现,儿童的检测时发展基本上不受学校知识或经验的影响。另外,两组儿童的检测时和智力测验分数之间都有中等程度的负相关。
