Bioethical issues in biostatistical consulting: development of a survey

To develop a survey, the Bioethical Issues in Biostatistical Consulting Questionnaire, for investigating bioethical issues in analysis, a comprehensive literature review was conducted to specify areas of bioethics. Through a focus group study and the evaluation by 10 biostatisticians, the questionnaire was constructed. Validation must involve a panel of experts. Now, test-retest reliability and factor analysis should be conducted on a group of eligible subjects.     

组织文化预览对企业并购绩效的影响

在Weber和Camerer实验范式的基础上,基于真实并购预览概念提出了组织文化并购预览,通过实验室模拟研究探索了组织文化预览对并购后绩效的影响。结果表明:(1)组织文化预览对提高并购后组织绩效有积极作用,其中双向组织文化预览对改善并购后的整体绩效以及主、并双方各自的绩效都有显著的积极作用,而单向组织文化预览未显示出显著的积极影响;(2)组织文化预览可能主要起效于并购后初期,在并购后短期内对整合组织文化有积极促进作用,利于并购后的快速整合。实验结果为组织文化预览在企业并购整合中的应用提供了理论依据和实证支持。     

Duchenne型肌营养不良基因诊断技术的发展及其哲学评析

Duchenne型肌营养不良(DMD)是发病率较高的神经系统遗传病,其基因突变机制复杂,探索简便、准确的基因突变检测技术是DMD研究的热点之一.随着分子生物学的进展,DMD基因诊断技术不断发展,经历了DNA印迹杂交、聚合酶链反应、生物芯片、多重连接探针扩增等.其发展过程带给我们许多哲学思考.     

大圆满(Dzogchen)及海德格尔的四维时间

关于时间,我们有太多的疑问,比如过去的事情就不再有了吗?未来是不可预期的吗?现在存在吗?时光的流逝是不可逆转的吗?什么是永恒?它与时间的关系如何?本文以藏传佛教大圆满传统的龙清巴和西方现象学派的海德格尔为例讨论时间的经验。他们都没有去构想永恒的生命,而是深入到时间流逝的现象和经验之中,揭示了一个全新的时间维度,即所谓第四时间或时间的第四维度。本文首先介绍大圆满传统中处理时间经验的一种修行,然后分析龙清巴的四时概念及其在佛教史上的意义,接着讨论海德格尔的四维时间概念,以及其追随者对这一概念的进一步讨论。最后在结论中,我将简单说明四维时间在这两个传统中的同异点,并探讨其相似点后的可能原因。     

论英美医事法立法体系

我国现阶段的有关医疗方面的法律、法规,在整个医疗卫生活动中起到了规范和制约的作用,但仍不完善.了解国外医事立法的历史和现状,有利于我国医事立法工作的开展.从英美法系医事立法出发,对英美法系的医事立法进行讲解和论述,从而起到借鉴的作用.     

权威与群体因素对中学生受暗示心理的影响研究

本研究在前人的基础上再次证实权威与群体是影响受暗示心理的主要因素,选取了即将参加高考的高三学生作为被试,从而证明该结论在不同的群体样本中都成立。同时也比较了两者影响作用的大小和在不同群体中的表现是否有差异。通过设计由两个群体暗示实验组、两个权威暗示实验组和一个控制组组成的实验来进行研究。研究表明在中学生群体中权威与群体都对受暗示心理有影响,但是群体的暗示作用更大,权威的暗示作用显得比较小甚至会出现相反的结果,这说明中学生和大学生相比,心理发展还处于不稳定时期,在受权威暗示上还存在一定程度的逆反心理。     

Common neural systems associated with the recognition of famous faces and names: An event-related fMRI study

Person recognition can be accomplished through several modalities (face, name, voice). Lesion, neurophysiology and neuroimaging studies have been conducted in an attempt to determine the similarities and differences in the neural networks associated with person identity via different modality inputs. The current study used event-related functional-MRI in 17 healthy participants to directly compare activation in response to randomly presented famous and non-famous names and faces (25 stimuli in each of the four categories). Findings indicated distinct areas of activation that differed for faces and names in regions typically associated with pre-semantic perceptual processes. In contrast, overlapping brain regions were activated in areas associated with the retrieval of biographical knowledge and associated social affective features. Specifically, activation for famous faces was primarily right lateralized and famous names were left-lateralized. However, for both stimuli, similar areas of bilateral activity were observed in the early phases of perceptual processing. Activation for fame, irrespective of stimulus modality, activated an extensive left hemisphere network, with bilateral activity observed in the hippocampi, posterior cingulate, and middle temporal gyri. Findings are discussed within the framework of recent proposals concerning the neural network of person identification.     

齐秦两国军事制度之比较

齐亡秦兴的历史命运虽由诸多因素促成,但不可否认,军事实力的差异是造成两国命运迥异的最直接原因。军事力量强弱与军事制度密不可分,军事制度是否健全、能否适应时代发展要求就成为决定一国军事实力强弱的关键,正是军事制度的差异对齐秦两国一亡一兴的最终命运产生了重要影响。     

Beyond the mental number line: A neural network model of number–space interactions

It is commonly assumed that there is an interaction between the representations of number and space (e.g., Dehaene et al., 1993, Walsh, 2003), typically ascribed to a mental number line. The exact nature of this interaction has remained elusive, however. Here we propose that spatial aspects are not inherent to number representations, but that instead spatial and numerical representations are separate. However, cultural factors establish ties between them. By extending earlier models (Gevers et al., 2006, Verguts et al., 2005) based on this hypothesis, the authors present computer simulations showing that a model incorporating this idea can account for data from a series of studies. These results suggest that number–space interactions are emergent properties resulting from the interaction between different brain areas.
