教师工作满意感与工作绩效:职业倦怠的中介效用

本研究通过考察398名幼儿园和小学教师的工作满意感、职业倦怠和工作绩效状况,采用纵向研究方法,借助于结构方程模型建构,以揭示其工作满意感、职业倦怠与工作绩效三者之间的关系。结果表明,(1)工作满意感对工作绩效存在显著的影响;(2)工作满意感通过职业倦怠中情感耗竭维度的中介作用影响教师的工作绩效;(3)职业倦怠中人格解体维度和成就感低落维度对工作绩效没有显著影响。     

胸腔镜肺切除术治疗肺部恶性肿瘤的合理性

通过回顾近年电视胸腔镜手术(VATS)在治疗非小细胞肺癌的进展,得出以下结论:在有经验的胸外科医师手中,VATS肺叶切除术是一种安全有效、死亡率和并发症发生率很低的术式.VATS肺叶切除是一种完全的肺部肿瘤切除手术,在有选择的早期病例可以达到与开胸手术一样的生存率.但这种术式并不适用于全部肺部恶性肿瘤和所有胸外科医师.     

社会自我效能感的结构、测量及其作用机制

班杜拉的自我效能理论一直是当代心理学的热点话题。作为社交情境中的特殊自我效能感,社会自我效能感是能够影响个人人际互动质量的重要心理因素之一,因此也逐渐开始受到研究者的关注。通过对国内外理论文章与实证研究的分析发现,社会自我效能感与社交自尊、社交果敢性、社交信心等相关概念有所不同,是指个体对自己社交能力的主观信念;其内涵在不同文化自我或情境的视角下可能存在差异,具有多元结构的可能性。社会自我效能感与个人特质、情绪、态度及行为等变量相关,并能够显著预测抑郁、社交焦虑、生活满意度、社会适应等变量。此外,社会自我效能感也在外向、性别角色、依恋、目标定向、网络人际交往的影响机制中起到中介作用,且能够对压力和不公平感所造成的消极影响具有一定的缓冲作用。然而有关研究仍存在诸多问题与不足,未来研究应该关注社会自我效能感内涵与结构的确定、测量工具的开发,并加强对其影响因素与影响效应的探索、系统模型的构建和跨文化研究的扩展。     

Adolescents' use of affiliative and aggressive strategies during conflict with romantic partners and best-friends

Objective: Developmental theory suggests romantic relationships present unique demands when adolescents transition from the interaction patterns of same-sex friendships to cross-gender interactions. A possible response is to incorporate behaviours of the other gender: girls adopting aggressive strategies and boys adopting affiliative ones. The goal of this study is to explore this hypothesis by comparing conflict resolution among romantic couples and same-sex best friends. Method: Observational methods were employed with 37 female best friends, 22 male best friends and 37 romantic couples. Of the romantic couples, 35 also were observed with a best friend. Affiliative and aggressive behaviours were tabulated during two conflict tasks. Results: Female best friends were more affiliative than male best friends and romantic partners; these latter dyads were more aggressive than the female best friends. Within group comparisons indicated that boys and girls decreased their affiliative behaviours, especially verbal humour, and increased their aggressive behaviours, especially teasing, when observed with the romantic partner compared to the best friend. Decomposing the romantic dyad, girlfriends displayed relatively more aggressive behaviours than their boyfriends, and boyfriends exhibited more affiliative behaviours. Conclusions: Findings shed light on gendered shifts in patterns of interaction as adolescents transition from same-sex friendships to romantic relationships.     

Personality traits in old age: measurement and rank-order stability and some mean-level change

Lothian Birth Cohorts, 1936 and 1921 were used to study the longitudinal comparability of Five-Factor Model (McCrae & John, 1992) personality traits from ages 69 to 72 years and from ages 81 to 87 years, and cross-cohort comparability between ages 69 and 81 years. Personality was measured using the 50-item International Personality Item Pool (Goldberg, 1999). Satisfactory measurement invariance was established across time and cohorts. High rank-order stability was observed in both cohorts. Almost no mean-level change was observed in the younger cohort, whereas Extraversion, Agreeableness, Conscientiousness, and Intellect declined significantly in the older cohort. The older cohort scored higher on Agreeableness and Conscientiousness. In these cohorts, individual differences in personality traits continued to be stable even in very old age, mean-level changes accelerated.     

循证医学教学模式对医学生消化内科实习效果的影响

探讨循证医学教学模式在消化内科临床实习教学中的运用效果.对入科实习的60名本科生,随机分为两组:循证教学模式组和传统教学模式组,每组30人,带教时间均为一个月.结果显示,两组间理论考试成绩比较无明显差异,而循证教学模式组临床答辩成绩与传统教学模式组比较差异有统计学意义(P＜0,05);循证教学模式组在提高学生的学习兴趣和主动性、分析和解决问题的能力及检索文献资料的能力等方面比率高于传统教学模式组(P＜0.01).因此,把循证医学教学模式运用于消化内科临床实习带教中,能提高学生的学习兴趣,增强学生的自学能力以及评判性思维能力.     

Perfectionism and multiphasic personality inventory (MMPI) indices of personality disorder

The present research tested the hypothesis that personal and social aspects of the perfectionism construct are related differentially to indices of personality disorders. A sample of 90 psychiatric patients was examined with respect to their scores on the Multidimensional Perfectionism Scale (MPS) and the personality disorder subscales (PDS) of the Minnesota Multiphasic Personality Inventory. The MPS provides measures of self-oriented, other-oriented, and socially prescribed perfectionism, whereas the PDS assess levels of various personality disorder symptoms. Zero-order and partial correlations indicated that the perfectionism dimensions of the MPS were related to various subscales of the PDS and, perhaps more importantly, that the findings vary as a function of the perfectionism dimension in question. The results are discussed in terms of the importance of perfectionism in personality disorder symptom patterns.     

精神病态与反社会型人格障碍间的关系

精神病态传统上一般被定义为一种人格(尤其是情感缺乏)的障碍,其次在小范围内才是行为障碍。尽管经常被相互混用,但是在诊断思路上,精神病态与反社会型人格障碍还是有区别的。二者不能简单等同起来,需明辨二者的关系。     

The MISTRA data: Forty-two mental ability tests in three batteries

The Minnesota Study of Twins Reared Apart (MISTRA) was initiated in 1979 and continued until 2000. It consisted of 139 pairs of twins who had been separated in early childhood and not re-united until adulthood, and members of their families. As part of a broader assessment, these participants completed 42 mental ability tests from three well-known test batteries. In this article, we present some background on the sample and tests and the correlation matrix of test scores, for the use of other researchers. As in all science, however, replication across samples of both tests and participants remains key to the development of ideas about mental ability.     

Spatial updating according to a fixed reference direction of a briefly viewed layout

Three experiments examined the role of reference directions in spatial updating. Participants briefly viewed an array of five objects. A non-egocentric reference direction was primed by placing a stick under two objects in the array at the time of learning. After a short interval, participants detected which object had been moved at a novel view that was caused by table rotation or by their own locomotion. The stick was removed at test. The results showed that detection of position change was better when an object not on the stick was moved than when an object on the stick was moved. Furthermore change detection was better in the observer locomotion condition than in the table rotation condition only when an object on the stick was moved but not when an object not on the stick was moved. These results indicated that when the reference direction was not accurately indicated in the test scene, detection of position change was impaired but this impairment was less in the observer locomotion condition. These results suggest that people not only represent objects’ locations with respect to a fixed reference direction but also represent and update their orientation according to the same reference direction, which can be used to recover the accurate reference direction and facilitate detection of position change when no accurate reference direction is presented in the test scene.
