《我为什么是无神论者》一书述评（二）

作者欧黑尔是“让美国人停下脚步，审视他们价值观的无神论者”。本书陈述了她的无神论不但是消极的，否认神、灵魂和天堂地狱等宗教主要元素的真实性，而且是积极的，展示一种非宗教的生活方式，依靠人类自己的力量创造大家共同的幸福生活。她的无神论以唯物主义为哲学基础，认为宗教的世界观是唯心主义的：她为唯物主义者辩诬．表述了唯物主义的基本特征及其优越性。以其主张政教分离的观念鲜明而坚定．曾推动美国最高法院判决在公立学校里限制宗教活动．因此也受到种种诅咒。     

芭特勒对萨特身体观的阅读探析

美国哲学家茱迪恩·芭特勒认为连串理所当然地跟性相关的论述,同时存有化了及固定化了物质性的身体.芭特勒阅读波伏娃的<第二性>,认为这并非就是萨特的<存在与虚无>于女性问题或处境上的应用.波伏娃曾说意识存在于一个人的身体当中,并且在文化的脉胳里,参与形成一个人的性别.芭特勒认为对萨特身体哲学的理解,在很多方面都能提高我们对波伏娃思想的欣赏,并认定她是一个具原创性的思想家.     

需求和接受的授权型领导匹配对下属工作结果的影响：情绪耗竭的中介作用

基于人-环境匹配理论和压力认知交互作用理论, 本文探讨了下属需求和接受的授权型领导匹配性对下属态度、行为和绩效的影响及情绪耗竭的中介作用。本文分别通过对150位领导与150位下属(研究1)、50位领导与243位下属(研究2)的配对样本开展两项多时点、多来源的问卷数据收集, 并采用跨层次多项式回归和响应面分析方法得出以下结论: (1)下属需求和接受的授权型领导失配会导致下属情绪耗竭; (2)相对于授权不足, 领导的过度授权更会导致下属情绪耗竭; (3)下属需求和接受的授权型领导匹配性通过作用于下属情绪耗竭进而影响下属对领导的满意度、组织公民行为和工作绩效。     

春秋齐国军事体制对我国预备役部队建设之启示

中国古代有作为的君王与将相都十分重视军队包括后备力量建设。春秋五霸之首齐桓公在贤相管仲的辅佐下改革内政,建立国鄙制,“作内政而寄军令”,在国的行政单位基础上建立起三军编制,推行军政合一,寓兵于民。行政官员平时处理政事;战时则带领精兵作战。由于士卒平时居住在一起,彼此熟悉,且福祸相依,因而战时配合默契,生死与共,具有极强的战斗力,为齐建立霸业奠定了基础。春秋齐国军事体制的成功实践,对于今天现代预备役部队建设,仍具有启示意义。     

Effect of Acute Psychological Stress on Motion-in-Depth Perception: An Event-Related Potential Study

The present study explored the intrinsic event-related potential (ERP) features of the effects of acute psychological stress on the processing of motion-in-depth perception using a dual-task paradigm. After a mental arithmetic task was used to induce acute psychological stress, a collision task was used to evaluate motion-in-depth perception. The error value and average amplitude of late slow waves (SW) were significantly larger for the earlier colliding spheres’ than for the later colliding spheres. The P1 peak latency in the left occipital region was significantly shorter than that of the right occipital region in the motion-in-depth perception task. Compared to the control condition, the estimated value of residual time-to-collision and error value were significantly reduced, and the N1 peak amplitude and the SW averaged amplitude were significantly increased in the stress condition. Longer motion-in-depth time improved discrimination accuracy and decreased the investment of cognitive resources. Acute psychological stress increased behavioral performance and enhanced attention resources on the motion-in-depth perception task together with greater investment of cognitive resources.     

公安民警的创伤后应激症状对执行功能的影响—基于Stroop范式的探究

公安民警常常身临应激和危险情境中,是创伤事件的易感人群,但其创伤后应激症状对执行功能的影响研究尚且缺乏。已有研究发现,具有创伤后应激症状的个体的执行功能存在缺陷,表现在对冲突信息的抑制能力受损以及对创伤相关信息的注意偏向和情绪唤起。本研究以公安民警为实验组被试,据其创伤后应激症状分为高低两组,在校大学生为对照组被试,采用Stroop范式探究创伤后应激症状对公安民警“冷”、“热”执行功能的影响。结果表明,具有创伤后应激症状的公安民警在“冷”、“热”执行功能上不存在缺陷,但仍在一定程度上受到创伤后应激症状的影响。启示对具有创伤后应激症状的公安民警进行干预时,应关注其症状的严重程度,在“热”执行功能上寻求更有效的干预方式。     

从《无神论——绪论》看宗教自由和反无神论观念

《无神论》是美国马丁(MICHAEL MARTIN)教授写的一部名著,副标题《哲学的合理性证明》,1990年出版。书前有一篇颇长的《绪论》,针对一些有神论者的批评,作了扼要的回应,从中可以看出当代西方宗教神学是如何抨击无神论的,以及他对这些抨击所作的逻辑反驳和对无神论的合理性证明。我特别感兴趣的问题,还有作者无意中透露出来的美国的意识形态和宗教自由问题。作者回忆说,他幼年受家庭影响,倾向无神论,但同时知道,无神论在美国民众的心目中是很坏的,因为“他们大多数人都信仰上帝”。记得“三年级的一天,我向一个有同情心的指导顾问透露…     

制止高官参与封建迷信、伪科学活动(二)

高官支持、带头搞伪科学、封建迷信,影响很坏高官们这些做法之所以影响很坏,是由于以下一些因素在起作用。(一)组织性和纪律观念的误用全国解放半个多世纪了。现在我国广大干部都是在党的教育下成长起来的,有的本身就是共产党员,他们都有很强的组织性和纪律观念,一般对上级领导人的批示和指示都不打折扣地贯彻执行。这无疑是对的。但另一方面,党的民主集中制原则规定,个人服从组织,少数服从多数,下级服从上级,全党服从中央;同时还规定,党员“对党的决议和政策如有不同意见,在坚决执行的前提下,可以声明保留,并且可以把自己的意见向党的上级…     

Calcium signaling in mitral cell dendrites of olfactory bulbs of neonatal rats and mice during olfactory nerve Stimulation and beta-adrenoceptor activation

Synapses formed by the olfactory nerve (ON) provide the source of excitatory synaptic input onto mitral cells (MC) in the olfactory bulb. These synapses, which relay odor-specific inputs, are confined to the distally tufted single primary dendrites of MCs, the first stage of central olfactory processing. beta-adrenergic modulation of electrical and chemical signaling at these synapses may be involved in early odor preference learning. To investigate this possibility, we combined electrophysiological recordings with calcium imaging in olfactory bulb slices prepared from neonatal rats and mice. Activation of ON-MC synapses induced postsynaptic potentials, which were associated with large postsynaptic calcium transients. Neither electrical nor calcium responses were affected by beta-adrenergic agonists or antagonist. Immunocytochemical analysis of MCs and their tufted dendrites revealed clear immunoreactivity with antibodies against alpha1A (Cav2.1, P/Q-type) and alpha1B (Cav2.2, N-type), but not against alpha1C (Cav1.2, L-type) or alpha1D (Cav1.3, L-type) calcium channel subunits. Moreover, nimodipine, a blocker of L-type calcium channels, had no effect on either electrical or calcium signaling at ON-MC synapses. In contrast to previous evidence, we concluded that in neonatal rats and mice (P5-P8), mitral cells do not express significant amounts of L-type calcium channels, the calcium channel type that is often targeted by beta-adrenergic modulation. The absence of beta-adrenergic modulation on either electrical or calcium signaling at ON-MC synapses of neonatal rats and mice excludes the involvement of this mechanism in early odor preference learning.     

The emergence of cultural self-constructs: autobiographical memory and self-description in European American and Chinese children

This study examined the emergence of cultural self-constructs as reflected in children's remembered and conceptual aspects of the self. European American and Chinese children in preschool through 2nd grade participated (N=180). Children each recounted 4 autobiographical events and described themselves in response to open-ended questions. American children often provided elaborate and detailed memories focusing on their own roles, preferences, and feelings; they also frequently described themselves in terms of personal attributes, abstract dispositions, and inner traits in a positive light. Chinese children provided relatively skeletal accounts of past experiences that centered on social interactions and daily routines, and they often described themselves in terms of social roles, context-specific characteristics, and oven behaviors in a neutral or modest tone. Findings are discussed in light of the self as a constructed meaning system of culture that emerges early in life.
