Coping with Daily Stress: The Role of Conscientiousness

The current study examined how specific coping strategies mediate the relationship between Conscientiousness (C) and positive affect (PA) in a large, multiethnic sample. Using an internet-based daily diary approach, 366 participants (37.6% Caucasian, 30.6% Asian American, 20.7% Hispanic, 9.1% African American) completed measures that assessed daily stressors, coping strategies used to deal with those stressors, and PA over the course of five days. In addition, participants completed a measure of the Five-Factor Model of Personality. Problem-Focused coping partially mediated the relationship between C and PA. Individuals higher in C used more problem-focused coping, which, in turn, was associated with higher PA. The findings of the current study suggest C serves as a protective factor from stress through its influence on coping strategy selection. Other possible mediators in the C-PA relationship are discussed.     

社会创造性的微观变化：基于虚拟仿真技术的研究

本研究将微观发生法设计和虚拟仿真技术相结合,考察了不同特质社会创造性大学生跨情境、跨时间的状态社会创造性的变化特点。结果表明：（1）在四种具体社会问题情境中,个体策略新颖性的变化表现出了跨情境的多样性特点,而策略实用性的变化则主要表现出了跨情境的一致性特点;（2）个体特质社会创造性对其状态社会创造性的表现的影响主要体现在策略的实用性上。     

视觉形状知觉在近似数量系统和计算流畅性关系中的作用

已有大量研究揭示了近似数量系统与计算流畅性的相关关系, 但缺少对二者关系原因的系统检验与论证。视觉形状知觉假设有别于传统的数量领域特异性解释, 认为对形状的快速知觉是近似数量系统与计算流畅性的共同认知机制, 即视觉形状的快速知觉能力可以解释二者之间的相关关系。近似数量系统和计算流畅性在加工过程中依赖对形状的快速知觉, 二者在加工过程中都涉及了复杂视觉刺激的快速处理。视觉形状知觉假设得到了一系列研究结果的支持, 但局限在视觉形状知觉与二者关系的探讨上, 视觉形状知觉在二者关系中作用的加工机制仍不清楚。未来研究需要结合多种研究方法和技术, 多角度深入探讨视觉形状知觉在二者关系中作用的认知与脑机制, 并将研究结果应用于数学课堂教学和计算困难的干预中。     

Infant behaviors influence mothers’ provision of responsive and directive behaviors

Mother–infant interactions are important to infant development because they are predictive of infants’ social, cognitive, and language development (0070 and 0150). Because maternal responsive and directive behaviors are associated with differential infant outcomes, it is important to investigate influences on mothers’ provision of responsive and directive behaviors. Yet, the dyadic interaction literature is predominantly unidirectional from maternal behavior to infant outcomes. Therefore, the current study examined infant initiating behaviors and consequent maternal responses in a sample of 26 13-month-old infants and their mothers, videotaped during 5 min of free-play. Findings revealed that infants produced a variety of initiatives, and that these different infant initiatives prompted differential patterns of maternal responsive versus directive behaviors. Further, results of analyses of divergent types of maternal directive behaviors – Responsive Directives, ReDirectives, and Intrusive Directives – also may help clarify major discrepancies in the current literature regarding the positive and negative effects of maternal directiveness.     

From Reading Minds to Social Interaction: Respecifying Theory of Mind

The aim of this paper is to show some of the limitations of the Theory of Mind approach to interaction compared to a conversation analytic alternative. In the former, mental state terms are examined as words that signify internal referents. This study examines children’s uses of ‘I want’ in situ. The data are taken from a corpus of family mealtimes. ‘I want’ constructions are shown to be interactionally occasioned. The analysis suggests that (a) a referential view of language does not adequately account for how mental state terms are used in talk, (b) the dominant methodology for examining children’s understanding of ‘desires’ is based on several problematic assumptions. It is concluded that participation in interaction is a social matter, a consideration that is obscured by Theory of Mind and its favoured methods.     

原发灶切除在转移性乳腺癌治疗中的地位

无论是国内还是世界其他国家,乳腺癌近年来已成为女性常患恶性肿瘤之首。早期乳腺癌通过手术、化疗、放疗及内分泌治疗等综合治疗后可以达到长期生存。然而对于晚期乳腺癌,特别是伴有远处转移的乳腺癌,疗效却不尽如人意。对于转移性乳腺癌,目前治疗优先选择毒性尽可能小的全身系统性治疗方案;而对于需要缓解症状或避免即将发生并发症（如皮肤溃疡、出血、真菌感染以及疼痛等）的情况可于全身治疗后行相应手术。然而对于转移性乳腺癌是否手术切除原发灶以及是否可从手术中获益,仍然充满争议。     

非小细胞肺癌 EG FR 基因突变检测与临床意义

采用荧光PCR法对199例晚期非小细胞肺癌（NSCLC ）组织进行表皮生长因子受体（EGFR ）基因突变检测,分析EGFR基因突变的分布特征及其与临床病理特征的相关性。结果显示56例（28．1％）存在EGFR基因突变,其中27例（13．6％）为外显子19突变,25例（12．6％）为外显子21突变,2例为外显子18突变,1例外显子20突变,1例外显子18和20的共突变。另外,除广东及安徽省铜陵市外,辽宁地区NSCLC患者EGFR基因突变率及主要突变类型与其他地区相符,常见于外显子19、21突变,其中腺癌、不吸烟患者突变率更高,更适宜EGFR-TKI靶向治疗。
