New Fathers’ Perceptions of Dyadic Adjustment: The Roles of Maternal Gatekeeping and Coparenting Closeness

Although the association between maternal gatekeeping and relationship functioning has been explored by a few studies, none of these have focused on fathers’ perceptions of these constructs. Given that today's new fathers are challenged by elevated expectations for active parenting and coparenting even as most new mothers remain primary caregivers of infant children, this is a critical omission. This study examined the associations between new fathers’ perceptions of maternal gatekeeping and change in dyadic adjustment as mediated through coparenting closeness. Maternal gatekeeping was reported by 182 fathers at 3 months postpartum, coparenting closeness was reported at 3 and 6 months postpartum, and dyadic adjustment was reported during the third trimester of pregnancy and at 9 months postpartum. Fathers’ perceptions of relative change in coparenting closeness from 3 to 6 months mediated associations between fathers’ perceptions of maternal gatekeeping at 3 months and relative change in dyadic adjustment from the third trimester to 9 months postpartum. In particular, findings indicate that greater perceived maternal gate opening was associated with higher levels of dyadic adjustment through higher levels of coparenting closeness, whereas greater perceived maternal gate closing was associated with lower levels of dyadic adjustment through lower levels of coparenting closeness. This study highlights the importance of studying fathers in the context of the family system and the role of the coparenting relationship at the transition to parenthood in couple relationship functioning.     

Development of a social interaction questionnaire for the trainers and mothers of children with disabilities participating in Dousa-hou (Japanese psycho-rehabilitation) camps

A 12-item Social Interaction Questionnaire was developed to measure the social interactions among trainers and mothers of children with disabilities in Dousa-hou camps. Dousa-hou is a Japanese psychological rehabilitation method which is widely used for children with mental retardation, cerebral palsy, and autism in Japan and other Asian countries. The primary focus of the rehabilitation method is to improve bodily movements, posture, and social support to patients and their first-degree relatives as well as promoting social interaction among participants. Two factors of interaction, (1) educational and daily life matters and (2) health and care matters, emerged through factor analysis. Cronbach coefficient alpha of the questionnaire was .91. The back-translated version of the Social Interaction Questionnaire also yielded two factors and Cronbach coefficient alpha of .87. It was found that mothers or first degree relatives (N=138; M = 43.5 yr., SD = 12.3) of the patients reported more social interaction than trainers when interacting with their child's trainer, supervisor, other trainers, and other mothers during six-day Dousa-hou camps.     

论元认知和智力的相互关系

元认知水平与智力活动之间关系密切。元认知由三部分组成：元认知知识、元认知体验和元认知技能,它与智力中的元成分、操作成分和知识获得成分密切相关。人知在人类智力因素中占有重要作用,是智力活动中的核心因素之一。智力也会影响元认知活动。它们之间相互影响、相互作用。     

应激对记忆影响的脑科学研究及其教育启示

大量脑科学的研究揭示,应激对与海马相关的陈述性记忆的调节主要通过应激激素,尤其是糖皮质激素的分泌而发生作用,而影响的方向取决于一些调节变量,包括糖皮质激素升高的水平以及记忆的不同阶段等。研究发现基底外侧杏仁核是糖皮质激素对记忆不同阶段产生差异性影响的关键部位。因此,在教育过程中,既要科学地认识应激对记忆的消极影响,又要有效利用应激对记忆产生的调节作用,来提高学生的学习效率。     

增殖和凋亡的单独与联合检测对垂体瘤侵袭性诊断的价值

垂体瘤是颅内常见的良性肿瘸,但却存在着较高的复发率。Jefferson于1940年提出侵袭性垂体腺瘸的概念,认为这部分垂体腺瘤的生物学行为介于良性垂体瘤和垂体癌之间。随后人们从分子生物学、病理学等多个角度对侵袭性腺瘸的发病机制进行了探讨,以期寻找到特异性的侵袭性指标。众所周知,细胞增殖能力的增强和凋亡的抑制是导致肿瘤恶性生物学行为的重要机制。但对垂体瘤的研究却发现有为数不少的侵袭性垂体腺瘸并不呈现高细胞增殖状态。而凋亡的研究则更是出现了不同甚至相反的结果,那到底是什么原因导致了侵袭性的形成呢？本文从细胞增殖和凋亡各自的临床意义以及其联合检测的角度探讨侵袭性的确切机制。

21世纪是通识教育与专业教育逐步走向综合的世纪,而综合性通识课程内容的构建则是通识课程改革的关键.为了有助于我国医学院校构建综合性通识课程,通过对不同国家和地区综合性通识课程内容的组织、设计和实施的分析,探讨了高等医学院校综合性通识课程内容的构建.     

系统生物学——中西医结合的平台

通过比较系统生物学与中医理论在整体观、系统观、预测性和预防性医疗以及个体化治疗等方面的相似之处,并分析中医和西医各自的优点和不足,提出中医和现代医学在系统生物学的基础上进行整合的必然性和可能性,系统生物学是中西医结合的平台.     

客体与空间工作记忆的分离：来自皮层慢电位的证据

利用128导事件相关电位技术,采用延迟匹配任务的实验范式,测查了16名正常被试在完成客体任务和空间任务时的皮层慢电位（slow cortical potentials,简称sp成分）,实验发现：在后部脑区,客体工作记忆与空间工作记忆在慢波活动的时间上存在分离,空间任务更早的诱发出负sp成分,并且空间任务激活更多的后部脑区;左下前额叶在客体工作记忆任务与空间工作记忆任务中都有激活,并且激活强度不存在显著差异;背侧前额叶主要负责客体信息的保持与复述,但左右背侧前额叶的激活强度存在不对称性。     

面孔加工特异性的事件相关电位研究

采用事件相关电位方法,以面孔、汽车、鸟和椅子为刺激,在汽车搜索作业及分类判断作业两种条件下考察了N170面孔特异性效应。结果发现,面孔在两种条件下均引起明显不同于其余三类物体的N170。实验任务对汽车刺激有明显的影响,具体表现为：在搜索作业下,汽车N170有接近面孔N170的趋势,其波幅显著大于鸟、椅子N170的波幅;在分类作业中,则没有这种显著的差异。从而为证明存在面孔识别的特异性神经机制提供了证据。     

试论《牟子理惑论》之真伪

《高僧传》、《祐录》等佛教文献记载佛法初传历史,依据的是《牟子理惑论》。《牟子理惑论》甚至影响了在南方翻译的佛经。汉末交州,社会安定,儒学盛行,学术自由,与海外交往密切,从而为佛教传播提供了条件,但也抑制了佛教传播范围和程度的进一步扩大,这是《牟子理惑论》创作的历史背景。《牟子理惑论》首先译Buddha为“佛”,并在中国南方介绍了佛“相好”制。
