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。     

The role of death qualification and need for cognition in venirepersons' evaluations of expert scientific testimony in capital trials

The purpose of this study was to investigate the role of death qualification in venirepersons' evaluations of expert scientific testimony in capital trials. 200 venirepersons from the 12th Judicial Circuit in Bradenton, FL completed a booklet that contained the following: one question that measured their attitudes toward the death penalty; one question that categorized their death-qualification status; the Need for Cognition (NFC) scale (Cacioppo, Petty & Kao, 1984); a summary of the guilt phase of a capital case (which included the cross-examination of the state's expert witness); verdict preference; five questions concerning participants' evaluations of the expert's testimony; the penalty phase of a capital case; sentence preference; and standard demographic questions. Results indicated that death-qualified venirepersons were more likely to demonstrate a low need for cognition and view ambiguous expert scientific testimony as valid, important in their decision-making processes, unbiased, and of high quality. Finally, death-qualified participants were more conviction- and death- prone than their excludable counterparts. Surprisingly, death-qualified and excludable jurors did not differ with respect to whether or not they felt that the expert followed correct procedures. Legal implications and applications are discussed.     

Experience in integrative negotiations: What needs to be learned?

In this research we focus on the roles of experience and understanding in fostering integrative negotiation performance. We report on two experiments in which we distinguish between understanding opponents’ general priorities among issues versus understanding their specific gains for particular offers. Although experience enhanced integrative performance even in the absence of understanding, we found that understanding the specific gains had an incremental effect on performance. We conclude that while generally acknowledging opponents’ interests is not sufficient, the additional inferential step of assessing their specific gains throughout the negotiation process is advantageous.     

The Influence of Ease of Retrieval on Judgment as a Function of Attention to Subjective Experience

The ease with which information comes to mind can impact judgment. We examine whether the influence of ease of retrieval is moderated by situational factors that call it to attention before judgment and by individual differences in experiential processing style, as measured by the rational experiential inventory scale (Pacini & Epstein, 1999). An ease of retrieval effect, indicated by less favorable evaluations of a proposal following the retrieval of many reasons advocating the proposal than following the retrieval of only a few, was found for high‐experiential style processors regardless of situational factors that made ease of retrieval salient. However, the effect was found among low‐experiential style processors only when ease of retrieval was explicitly called to their attention prior to judgment.
