SSCI中自我表露研究的计量分析

采用文献计量学方法,利用SSCI对1975~2005年有关自我表露的文献进行统计分析,以揭示30年来自我表露研究主要涉及的学科领域、源期刊、研究者及其特点,特别将我国香港、台湾、大陆研究者的38篇本土研究进行了整理分析。从分析中可以看到我国本土研究虽然数量少,但研究热点、对象、方法等与国外研究基本一致,与此同时一些研究还关注到中国文化对表露的影响。从研究脉络来看,我国本土研究理论性有待加强

Co-induction of long-term potentiation and long-term depression at a central synapse in the leech

Most studies of long-term potentiation (LTP) have focused on potentiation induced by the activation of postsynaptic NMDA receptors (NMDARs). However, it is now apparent that NMDAR-dependent signaling processes are not the only form of LTP operating in the brain [Malenka, R. C., & Bear, M. F. (2004). LTP and LTD: An embarrassment of riches. Neuron, 44, 5–21]. Previously, we have observed that LTP in leech central synapses made by the touch mechanosensory neurons onto the S interneuron was NMDAR-independent [Burrell, B. D., & Sahley, C. L. (2004). Multiple forms of long-term potentiation and long-term depression converge on a single interneuron in the leech CNS. Journal of Neuroscience, 24, 4011–4019]. Here we examine the cellular mechanisms mediating T-to-S (T → S) LTP and find that its induction requires activation of metabotropic glutamate receptors (mGluRs), voltage-dependent Ca²⁺ channels (VDCCs) and protein kinase C (PKC). Surprisingly, whenever LTP was pharmacologically inhibited, long-term depression (LTD) was observed at the tetanized synapse, indicating that LTP and LTD were activated at the same time in the same synaptic pathway. This co-induction of LTP and LTD likely plays an important role in activity-dependent regulation of synaptic transmission.     

广东省城乡初中生元认知水平比较研究

研究采用自编问卷和访谈法对城乡初中生进行元认知水平的对比研究,结果表明：1）城乡初中生元认知水平总体差异显著,农村初中生的元认知水平总体低于城市初中生的元认知水平。2）城乡初中生在认知前元认知体验和认知中元认知知识维度上差异显著。认知前元认知知识、认知中元认知体验、认知后元认知知识、认知后元认知体验之间无显著性差异。建议加强教师和学生元认知训练,提高学生元认知水平。     

镇静与镇痛在ICU机械通气患者中的应用变化

探讨ICU内机械通气患者应用镇痛剂、镇静剂及肌松剂的情况及其对机械通气和预后的影响。回顾性分析我院中心ICU2006年、2007年收治的244例行有创机械通气治疗超过48h患者的临床资料,并将患者分为2006年组和2007年纽,用统计软件分析患者在年龄、性别、入ICU时APACHEⅡ评分、血糖、血浆白蛋白、基础疾病,气管插管时间、机械通气时间、ICU住院天数、镇痛与镇静剂应用的时间、机械通气时是否使用肌松剂、Ramsay评分及病死率方面是否存在差别。统计分析显示2006年组和2007年组在年龄、性剐、入ICU时APACHEⅡ评分、血糖、血浆白蛋白、是否使用肌松剂及基础疾病方面无差别;与2006年组相比2007年组患者气管插管时间、机械通气时间及ICU住院天数均缩短,镇痛与镇静剂应用时间均缩短,Ramsay评分降低,病死率下降。提示对机械通气的危重症患者应合理使用镇痛剂与镇静剂。     

抗震救灾官兵心理健康状况及相关因素分析

了解参加抗震救援官兵的心理健康状况及相关因素,为进行心理危机干预提供科学依据。方法 采用症状自评量表（SCL-90）、简易应对方式问卷（SCSQ）、艾森克人格问卷简式量表中国版（EPQ-RSC）及军事应激症状核查表（PCL-M）,对空军某部抗震救援官兵进行心理测评。结果 消极应对和PCL-M总分与SCL-90总分及各因子分呈正相关（p＜0.01）;积极应对方式与PCL-M总分、SCL-90总分及4项因子分呈低相关（p＜0.01）;不同气质类型PCL-M总分及SCL-90各项统计指标之间均有显著性差异（p＜0.01）。结论 气质类型与应对方式对心理健康状况有很大影响,个别官兵应及时给予心理疏导     

非正态分布下概化理论方差分量变异量估计

方差分量估计是概化理论的必用技术,但受限于抽样,需要对其变异量进行探讨。采用Monte Carlo数据模拟技术,探讨非正态数据分布对四种方法估计概化理论方差分量变异量的影响。结果表明：（1）不同非正态数据分布下,各种估计方法的“性能”表现出差异性;（2）数据分布对方差分量变异量估计有影响,适合于非正态分布数据的方差分量变异量估计方法不一定适合于正态分布数据。     

双任务干扰的注意资源限制机制:来自汉字笔画数效应的证据

该研究的两个实验采用心理不应期范式,探讨了重叠任务情境下双任务的相互干扰机制。实验中被试相继完成高低音的辨别任务(T1)和汉字外在特征(颜色或笔画数)的任务判断(T2),T1和T2间采用变化的SOA。结果发现:(1)T1的反应选择导致T2的加工成绩大幅下降,PRP效应非常显著。(2)当T1占据中枢瓶颈时,T2和T1在中枢瓶颈中并行得到加工并导致T1的加工效率显著下降。(3)由于注意资源的有限性,具有自动激活特征的汉字同样受瓶颈机制的限制。只要存在对注意资源的二次分配就会存在瓶颈的调节机制。     

《孟子》对戴震《原善》的影响

《孟子》在义理和话语两方面深深影响到戴震的《原善》。戴震将《易传》的“继善成性”与孟子的性善论区别为两个问题,前者是泛论,后者专论人性。受孟子断言“天之生物使之一本”的鼓舞,戴震严厉批评宋儒所谓性分义理、气质两种的学说犯了“二本”的错误。《原善》关于心的论述,关于“仁义礼智圣”和“条理”话语的使用,都鲜明表现出《孟子》的启发和影响。     

Regulatory Focus and Subjective Well-Being: The Mediating Role of Coping Styles and the Moderating Role of Gender

Abstract

Although previous research has suggested that regulatory focus may exert considerable impacts on individuals’ subjective well-being (SWB), little research has explored the mechanism for this relation and the potential gender difference. The current study investigated the potential mediating effects of coping styles on the relationship between regulatory focus and three aspects of SWB (indicated by life satisfaction, positive affect, and negative affect) among Chinese adolescents. Total of 2943 Chinese adolescents participated in this cross-sectional survey and completed self-reported questionnaires (M_age = 14.47, SD?=?1.59, 44.50% boys). Hypothesized pathways were tested by structural equation models. Results showed that regulatory foci were significantly associated with SWB. Promotion focus predicted SWB mainly through problem-focused coping, and the mediating effects of emotion-focused coping were also observed; Prevention focus predicted SWB mainly through emotion-focused coping, and the mediating effects of problem-focused coping were observed. Furthermore, relative to boys, the prediction of problem-focused coping on life satisfaction was stronger and the prediction of promotion focus on life satisfaction was weaker for girls. These findings provide a new approach to understand the mechanism for the relationship between regulatory foci and SWB, and indicate the gender differences of this process.
