The basic traumatic situation in the analytical relationship1

The author attempts to develop a concept of psychic trauma which would comply with the nucleus of this Freudian notion, that is, an excess of excitations that cannot be processed by the mental apparatus, but which would also consider the functions and the crucial role of objects in the constitution of the psychism and in traumatic conditions, as well as taking into account the methodological positioning according to which the analytical relationship is the sole possible locus of observation, inference and intervention by the psychoanalyst. He considers as a basic or minimal traumatic psychoanalytical situation that in which a magnitude or quality of emotions exceeds the capacity for containment of the psychoanalytical pair, to the point of generating a period or area of dementalisation in the psyche of one or both of the participants, of requiring analytical work on the matter and promoting a signifi cant positive or negative change in the relationship. Availing himself of Bion's theory about the alpha function and the metapsychological conceptions of Freud and Green concerning psychic representations, he presents two theoretical formulations relating to this traumatic situation, utilising them according to the ‘altered focus’ model proposed by Bion. He presents three clinical examples to illustrate the concept and the relevant theoretical formulations.     

Graph coloring, minimum-diameter partitioning, and the analysis of confusion matrices

It is well known that minimum-diameter partitioning of symmetric dissimilarity matrices can be framed within the context of coloring the vertices of a graph. Although confusion data are typically represented in the form of asymmetric similarity matrices, they are also amenable to a graph-coloring perspective. In this paper, we propose the integration of the minimum-diameter partitioning method with a neighborhood-based coloring approach for analyzing digraphs corresponding to confusion data. This procedure is capable of producing minimum-diameter partitions with the added desirable property that vertices with the same color have similar in-neighborhoods (i.e., directed edges entering the vertex) and out-neighborhoods (i.e., directed edges exiting the vertex) for the digraph corresponding to the minimum partition diameter.     

关系研究的新取向：社会网络分析

社会网络分析（Social Network Analysis, SNA）是用社会实体之间的关系来描述、解释和预测社会现象的一种研究取向。SNA提供了深入探究社会环境特征及其对个体心理发展影响的一种方法。本文基于SNA的发展历程,依次介绍了中心性分析、小团体分析、位置分析、QAP以及统计模型法。SNA在社会学研究中得到了较多应用,近年来在心理学研究中开始受到重视。     

加速追踪设计的方法和应用

加速追踪设计(ALD)是一种选择相邻多个群组同时进行短期追踪研究, 获得在测量上有重叠的多个群组追踪数据, 对多个群组数据进行合并建构一条在时间跨度上较长的发展趋势或增长曲线的方法。ALD结合真追踪和横断设计的特征, 既保持真追踪设计的大部分优点, 克服真追踪研究中由于重测效应和被试缺失导致的问题, 又尝试分离年龄、群组和历史时间效应, 在发展心理研究有重要应用。已有研究探讨ALD的数据分析方法、ALD的有效性及设计特征。未来研究应关注拓展设计条件下ALD的适应性, 探索非线性假设或群组效应显著时的数据分析方法和ALD中缺失数据处理问题。     

追踪研究方法在国内心理研究中的应用述评

以1982~2012年中国期刊网收录的88例追踪研究为对象,从应用现状、设计特征、数据处理三方面分析和评估追踪研究方法在国内心理研究的应用情况及存在的问题。结果显示,2005年之前追踪研究方法应用增长缓慢,2005年开始呈显著增长趋势,研究对象以未成年及成年早期群体为主。主要采用固定样本追踪设计,大部分研究测量2-3次、样本量在10~300之间、持续时间在3年内。61例有缺失的研究中,38例用删除法处理缺失;主要运用 HLM、方差分析、t检验和SEM分析追踪数据。相当部分研究存在测量次数少、样本量较小、持续时间短、被试缺失严重及数据处理方法相对陈旧问题。追踪研究方法的应用应注意,根据理论模型和研究有效性要求确定设计类型和设计特征,根据数据特征选择缺失处理方法和追踪数据分析方法。     

计划缺失设计——通过有意缺失让研究更高效

缺失值是社会科学研究中非常普遍的现象。全息极大似然估计和多重插补是目前处理缺失值最有效的方法。计划缺失设计利用特殊的实验设计有意产生缺失值, 再用现代的缺失值处理方法来完成统计分析, 获得无偏的统计结果。计划缺失设计可用于横断面调查减少(或增加)问卷长度和纵向调查减少测量次数, 也可用于提高测量有效性。常用的计划缺失设计有三式设计和两种方法测量。     

中国当代研究生的情感素质现状及其影响因素

为揭示当代研究生情感素质及所受因素影响状况, 用自编问卷调查全国3类地区14座城市51所高校的10056名研究生。结果发现：研究生情感素质呈2层面6大类33种情感的结构; 爱国感、责任感、信用感、自立感、自尊感、成就感等水平较高, 正直感、宽恕感、人文美感、表达自己情绪能力等较低; 不同性别、获奖经历、学科研究生的情感素质有结构性差异; 核心价值观认同、对舆论关注、人际关系、自我要求等对其情感素质有正向影响; 研究生理智情感等高于本专科生。总之, 当代研究生情感素质总体尚好, 各部分发展不均衡, 发展水平受社会、人际和自我等多方因素影响。     

进展性脑卒中诊治及相关因素分析

进展性脑卒中是缺血性脑血管病最常见的一个临床现象,进展性脑卒中的存在严重影响卒中患者的预后。迄今为止,关于其流行病学资料、发病机制、诊断标准、治疗均是极具挑战性的问题。进展性脑卒中可能是多种原因、多种病理机制所产生的多种状态的组合,治疗的手段应该以开放动脉或通过全身治疗的方法来增加脑灌注压为主。     

Treatment of Missing Data: Beyond Ends and Means

The ethical decision making process behind the treatment of missing data has yet to be examined in the research literature in any discipline. The purpose of the current paper is to begin to discuss this decision-making process in view of a Foucauldian framework. The paper suggests how the ethical treatment of missing data should be considered from the adoption of this theoretical framework.
