Relations between coparenting and father involvement in families with preschool-age children

A sample (N = 112) composed primarily of European American and middle-class two-parent families with a resident father and a 4-year-old child (48% girls) participated in a longitudinal study of associations between coparenting and father involvement. At the initial assessment and 1 year later, fathers reported on their involvement in play and caregiving activities with the focal child, and coparenting behavior was observed during triadic family interactions. Structural equation modeling was used to test cross-lagged associations between coparenting behavior and father involvement. Overall, paths from father involvement to coparenting behavior were significant, but paths from coparenting behavior to father involvement were not. Specifically, greater father involvement in play was associated with an increase in supportive and a decrease in undermining coparenting behavior over time. In contrast, greater father involvement in caregiving was associated with a decrease in supportive and an increase in undermining coparenting behavior. Multigroup analysis further showed that these cross-lagged relations did not differ for dual-earner families and single-earner (father) families, but these relations appeared to differ for families with focal daughters and families with focal sons. These findings highlight the potential for fathering to affect coparenting and the importance of the role of contextual factors in coparenting-fathering relations.     

Attachment dismissal predicts frontal slow-wave ERPs during rejection by unfamiliar peers

Attachment representations are thought to provide a cognitive-affective template, guiding the way individuals interact with unfamiliar social partners. To examine the neural correlates of this process, we sampled event-related potentials (ERPs) during exclusion by unfamiliar peers to differentiate insecure-dismissing from securely attached youth, as indexed by the child attachment interview. Thirteen secure and 10 dismissing 11- to 15-year-olds were ostensibly connected with two peers via the Internet to play a computerized ball-toss game. Actually, peers were computer generated, first distributing the ball evenly, but eventually excluding participants. Afterward children rated their distress. As in previous studies, distress was related to a negative left frontal slow wave (500-900 ms) during rejection, a waveform implicated in negative appraisals and less approach motivation. Though attachment classifications were comparable in frontal ERPs and distress, an attachment-related dismissal dimension predicted a negative left frontal slow wave during rejection, suggesting that high dismissal potentially involves elevated anticipation of rejection. As expected, dismissal and self-reported distress were uncorrelated. Yet, a new approach to quantifying the dissociation between self-reports and rejection-related ERPs revealed that dismissal predicted underreporting of distress relative to ERPs. Our findings imply that evaluations and regulatory strategies linked to attachment generalize to distressing social contexts in early adolescence.     

时空隐喻研究的新问题:时间表征的左右方向性

传统的时空隐喻研究主要通过启动范式来研究空间中的前后轴线和上下轴线与时间表征的关系;而近年来,研究者们通过综合运用排序法、判断法、比较法和线索范式,证明了个体会用左右轴线来表征时间.由于传统的理论无法很好地解释时间表征的左右方向性,研究者们倾向于用具身理论(embodiment theory)来解释这一现象.为了深化对空间轴线和时间表征之间的关系的认识,需要统一研究方法、整合不同理论并在神经机制层面上开展新的研究.     

“投桃报李”——互惠理论的组织行为学研究述评

互惠是一种存在于各种社会文化中的人际交往规范.组织行为学中许多研究都是通过互惠理论来解释变量之间的内部作用机制.文章回顾并讨论了互惠的涵义,不同互惠类型的特点及互惠的测量方式.此外.还论述了不同类型互惠对社会交换方式产生的影响.依据现有的互惠研究成果,分析了互惠发挥影响的内在作用机制是通过:互惠各方的价值观、互惠过程中各方感知到的风险、各方冲突的程度这三种途径来实现的.最后,根据现有互惠理论的研究成果提出该领域的未来发展应从研究设计和研究内容两方面进行扩展.     

医疗改革的公众参与问题研究

公众参与有助于增强医疗改革政策制定的透明度和有效性;但如何使公众能真正参与并影响医疗改革是亟需解决的难题.回顾国外卫生政策制定过程中公众参与的实践经验;发现我国医疗改革公众参与需要从协商监督机制建构、直接参与度设计以及价值观建构三方面开展.     

CyclinD1、VEGF、Flt-1在肝细胞癌中的表达及临床意义

探讨肝细胞癌( Hepatocellular carcinoma,HCC)、胆管癌、肝硬化及正常肝组织中周期素D1 (CyclinD1)、血管内皮生长因子(VEGF)及血管内皮生长因子受体(Flt-1)蛋白表达的意义及其与肝癌生物学行为关系.对52例符合要求的HCC组织、10例胆管癌组织、10例肝硬化组织及10例正常肝组织采用免疫组化S-P法检测CyclinD1、VEGF及Flt-1蛋白.CyclinD1、VEGF及Flt-1在HCC的强阳性表达率分别为55.8％、55.8％及67.3％,均显著高于胆管癌、肝硬化及正常肝组织(P＜0.001).CyclinD1及VEGF表达与肿瘤包膜完整、血管侵犯及肿瘤分化程度明显有关(P＜0.05);Flt -1与肿瘤分化程度明显有关(P＜0.05).CyclinD1与VEGF间、CyclinD1与Flt-1间及VEGF与Flt-1间的蛋白表达均呈正相关(R=0.445,P＜0.01、R=0.368,P＜0.01、R=0.332,P＜0.01).CyclinD1、VEGF及Flt-1蛋白的过表达可促使肝癌细胞增殖,使肝癌细胞具有更强的侵袭力,与肝癌的发生、发展密切相关.

小学教师的创造力培养观与创造性教学行为的关系:教学监控能力的中介作用

用创造力培养观、教学监控能力和创造性教学行为问卷对430名小学教师进行调查,考察三者之间的关系,并着重对教学监控能力在其中的中介作用进行分析。结果表明:(1)创造力培养观、教学监控能力及其各个维度对创造性教学行为都有正向预测作用;(2)教学监控能力的计划准备性、控制调节性、评价反馈性、课后反省性及作为一个整体在创造力培养观与创造性教学行为之间均具有显著的中介效应。这一发现提示教师培训工作应重视教师教学监控能力的实际增长,这样才能使教师已经接受的创造教育理念落实到创造性教学行为上。
