先天易的数学基础初探——试论先天卦序与二进位制

本文从自然数及其记数法的基本慨念出发。辨析了与二进位制相关的几个容易混淆的概念,指出序数概念的引入在近代数学发展中有重要意义。作为邵雍数学学派的数学基础,先天易是数学史上第一个专门定义的序数体系,该序数体系在数学史上率先采用了二进位制记数法。先天易作为二进制序数体系这一事实在明清时期引起不同的反响,反对者认为它使易道沦落,大数学家汪莱则从P进制的角度论证它的优越性。本文最后还对近年来反对先天易与二进制有关的两种典型观点进行了剖析．指出其谬误所在。     

Emotional and autonomic responses to visual traumatic stimuli

A fine-grain analysis of autonomic responses are presented with the purpose of extending the conclusions from a previously published paper (Christianson & Nilsson, 1984) on emotional and memorial responses to traumatic visual stimuli. Control subjects were presented with a series of 18 slides of neutral faces, whereas the experimental subjects were presented with six slides of horrible facial injuries in positions 7–12, interspersed between six slides of neutral faces in the beginning, and six slides of neutral faces at the end of the series. The time course of heart rate (HR) and skin conductance (SC) during stimulus presentation was recorded. These data showed an initial pattern of increase in SC, but not in HR. This pattern was subsequently replaced by a combined increase in both SC and HR. The results are discrepant to previous work and are interpreted as effects of not informing the subjects about the gruesome slides to be presented.     

The role of age on reactivity and memory for emotional pictures

The purpose of this study was to investigate subjects' reactivity to emotional pictures and their recollection of these pictures, and to examine these two factors as they relate to age. Adolescents and young adults were shown emotionally arousing scenic pictures for long (4-s) and very brief (50-ms) durations. Recognition of the pictures and recall and recognition of words presented along with the pictures were assessed both immediately after the presentation and six weeks later. The results showed that very negative pictures are retained better than neutral or even positive pictures, and that very negative pictures reduce memory for associated information. It was also found that adolescents show a somewhat lower reactivity to very negative pictures and a higher degree of retention of these pictures than adults. The results are discussed in relation to (a) habituation effects, (b) strategies that subjects might develop to block emotional involvement, and (c) the notion that watching violence might serve as a powerful prime to socially undesirable behaviour.     

Personality organization defined by DMT and the Structural Interview

The psychoanalytic concept of Personality Organization (PO) may be operationalized by means of a Structural Interview as well as by means of psychological tests. The present study utilized the Structural Interview and a projective test called the Defence Mechanism Test (DMT) to operationalize the PO concept on a sample of 50 psychiatric inpatients. The reliability of the PO judgements were found to be acceptable for both the Structural Interview and the DMT. The validity, which was estimated as the correlation between the two methods, was also found to be substantial. The conclusion is that the concept of PO may be reliably operationalized for psychiatric patients and seems to have concurrent validity. Both the DMT and the Structural Interview may be used for differential diagnosis of PO.     

The law and counselor ethics

Counselors cannot look only to the law to solve their professional problems in dealing with information about students. Nevertheless, they must understand confidentiality, privilege, and privacy in the context of ethical standards and legal requirements if they are to meet their responsibilities to clients, the profession, and to themselves.     

Evaluation of long term effects of phonemic awareness training in kinderarten: Illustrations of some methodological problems in evaluation research

The long-term effects of phonemic awareness training in kindergarten were evaluated by studying various aspects of reading, spelling, and oral phonological skills in school. In the kindergarten-part of the study 95 children divided into three experimental and two control groups took part. One year later 83 of them were identified and tested in school. The children who participated in the phonemic training program seemed to have benefited from it to some extent. At least they improved their scores on phonemic synthesis tests in school. Some children in the middle and high range of pretest performance seem to have avoided a risk for reading failure to a greater extent than the corresponding children in the control groups. It is suggested that phonemic training contributes to the development of accurate concepts of reading in the preschool child and makes the child less confused when confronted with formal reading instruction in school. Great variances, ceiling effects, and group heterogeneity created many difficulties in evaluating the training effects. The various methodological problems implied in evaluation research with nonequivalent control group design were analysed and illustrated with data from the present research.     

Can phonemic awareness be trained in kindergarten?

The effect of a training program designed to develop phonemic awareness skills in kindergarten was assessed in a study involving three experimental groups and two control groups. The degree of structure imposed upon the program was varied in the experimental groups. One control group was trained in non-verbal auditory discrimination, and the second control group followed the ordinary preschool program during the 6–8 week observational period. A clear improvement in the ability to segment and blend three-phoneme words was observed in the highly structured training cohdition, especially among the children with poor pre-test performance, while no clear changes from pre- to post-test were found in the other groups. It was concluded that phonemic awareness can be developed in prereaders outside the context of formal reading instruction.     

内隐关系评估程序(IRAP)：测量原理及应用

内隐关系评估程序(Implicit Relational Assessment Procedure, 简称IRAP)是基于关系结构理论直接测量社会认知、信念或态度的新内隐测量方法, 具备一定的可靠性和有效性, 并与其它相关测量方法的适用性存在一定差异。不同的理论模型为IRAP的不同效应提供了解释。IRAP最初应用于临床诊断性研究, 新近已扩展到自我、社会认知、群体和态度等研究领域。进一步验证不同形式IRAP的信效度、探究IRAP的心理机制及产生的心理效应、在不同领域发挥IRAP的方法优势等将是未来研究的重要方向。     

EMPLOYEE SELF-SERVICE TECHNOLOGY ACCEPTANCE: A COMPARISON OF PRE-IMPLEMENTATION AND POST-IMPLEMENTATION RELATIONSHIPS

Implementation of employee self-service (ESS) technology presents a variety of challenges for organizations as they strive to maximize return on investment and change management. Using a research framework grounded in the theory of planned behavior, this study examines factors that enhance user acceptance of ESS technology both before and after implementation. Results suggest that employees are more likely to intend to use ESS technology when they have positive attitudes toward using it and when subjective norms in the organization support use of the technology. Perceived organizational support (POS) enhanced the effect of managerial pressure on perceptions of normative beliefs supporting use of the technology post-implementation. Implications of the research and future research directions are discussed.
