Absolute and Relative Decision Processes in Eyewitness Identification

A prominent and long-standing theory of eyewitness identification decision making distinguishes between absolute judgments, based on the lineup members' match to the witness's memory of the perpetrator, versus relative judgments, based on match values relative to other lineup members. This distinction was implemented in a computational model and simulations showed that the model predicts an accuracy advantage for absolute judgments over relative judgments under some conditions. The present experiment tested this prediction by evaluating the accuracy of witnesses instructed to use relative or absolute rules. Contrary to predictions, the overall analysis did not show an absolute advantage. Additional exploratory analyses showed a relative advantage when the suspect was surrounded by high-similarity foils. These results are consistent with a model that assumes that side-by-side comparisons of lineup members increase diagnostic accuracy by allowing witnesses to give greater weight to more diagnostic features and less weight to less diagnostic features.     

人工智能决策的公平感知

不平等问题是全球社会和经济发展需要应对的首要挑战,也是实现全球可持续发展目标的核心障碍。人工智能(artificial intelligence, AI)为缓解不平等、促进社会公平提供了新的途径。然而,新近研究发现,即使客观上AI决策具有公平性和准确性,个体仍可能对AI决策的公平感知较低。因此,近年来越来越多的研究开始关注AI决策公平感知的影响因素。然而,目前研究较为分散,呈现出研究范式不统一、理论不清晰和机制未厘清等特征。这既不利于跨学科的研究对话,也不利于研究者和实践者对AI决策公平感知形成系统性理解。基于此,通过系统的梳理,现有研究可以划分为两类:(1) AI单一决策的公平感知研究,主要聚焦于AI特征和个体特征如何影响个体对AI决策的公平感知;(2) AI-人类二元决策的公平感知研究,主要聚焦于对比个体对AI决策与人类决策公平感知的差异。在上述梳理基础上,未来研究可以进一步探索AI决策公平感知的情绪影响机制等方向。     

信息呈现顺序对公平判断形成的影响

在公平启发理论的基础上,以130名大学生为被试采用实验室实验探讨了信息呈现顺序对公平判断形成的影响。结果表明：（1）信息呈现顺序能够影响人们的公平判断——当结果适宜性信息更早获得时,结果公平对公平判断的影响要大于结果适宜性信息较晚呈现时的影响;（2）公平形式偏好对公平判断的信息效应具有调节作用,即当高偏好信息先于低偏好信息出现时,公平判断的顺序效应会得到加强;而在低偏好信息先于高偏好信息出现的情况下,公平判断的顺序效应会被减弱。     

Agendas,Relevance and Dialogic Ascent

E. C. W. Krabbe characterizes a metadialogue as a dialogue about a dialogue, which in turn, is characterized as a ground level dialogue. Krabbe raises a number of interesting questions about this distinction, of which the most pressing is whether the difference between ground level and metadialogues can be drawn in a principled and suitably general way. In this note, I develop the idea that something counts as a metadialogue to the extent that it stands to its ground level counterpart in a relation of irrelevance. The irrelevance in question subsumes a triple of subconcepts: strategic relevance, agenda-relevance and irredundancy-relevance.     

The Relevance of Intention in Argument Evaluation

The paper discusses intention as a rhetorical key term and argues that a consideration of rhetor’s intent should be maintained as relevant to both the production and critique of rhetorical discourse. It is argued that the fact that the critic usually has little or no access to the rhetor’s mind does not render intention an irrelevant factor. Rather than allowing methodological difficulties to constrain critical inquiry, I suggest some ways in which the critic can incorporate the rhetor’s intention in evaluating argumentation. To this end, a standard of fairness is presented. The paper was presented at the 6th International Conference on Argumentation in Amsterdam, June 27–30, 2006.     

幽门螺杆菌cagA基因多态性对临床结局的影响:东亚菌株和西方菌株

CagA蛋白是幽门螺杆菌最重要的毒力因子之一.目前已证实cagA基因存在东亚及西方两种亚型.幽门螺杆菌产生CagA蛋白,注入胃上皮细胞后在其羧基端EPIYA重复序列区进行酪氨酸磷酸化,进而与SHP-2酪氨酸磷酸化酶相互作用,参与上皮细胞的信号传导,导致细胞骨架结构的重排,引起细胞表面形状的改变和细胞动力的增强,造成细胞异常的增殖和运动,在胃癌的发生中起了主要作用.cagA基因的羧基端EPIYA重复序列被认为是区分东亚型和西方型菌株的分子标记,东亚型CagA与SHP-2亲和力大于西方型,最终影响着不同CagA+菌株感染的临床表现.     

老子之道与佛教空性的比较研究

对于物质世界的根本实相:老子认为是存在于天地之先的道,佛教认为是具有复杂结构的空性。老子之道与佛教的空性,客观上存在融通及相似之处,这对于促进现代科学及哲学的发展是具有积极意义的。     

公正的启发理论述评

组织公正感包括分配公正、程序公正、互动公正等重要的组成要素。尽管这些公正感的构成要素有不同的内涵和影响因素,然而在许多情况下,这些要素之间有较高的一致性。与过去注重这些要素的差异性相反,Lind看到了这些公正感要素之间的一致性,提出了试图整合这些一致性的公正理论：公正的启发理论。该文比较全面地介绍了公正的启发理论的含义,如何启发等核心概念,并对启发理论存在的问题进行了分析,指出了启发理论研究的方向。     

THE ESCHATOLOGICAL THEOGONY OF THE GOD WHO MAY BE: EXPLORING THE CONCEPT OF DIVINE PRESENCE IN KEARNEY, HEGEL, AND HEIDEGGER

Abstract: While heightening the nihilistic tension underlying the discourse of Richard Kearney, I highlight the positive contribution his book The God Who May Be makes to the debate concerning the need for a postmodern revitalization of religious symbolism. I argue for three qualifications of Kearney's argument, suggesting, in response to Kearney's exclusionary approach to the God who "neither is nor is not but may be," a God whose possibility for meaningfulness arises as an "eschatological theogony" from out of the chaos (confusion and openness) of contemporary religious symbolism. Arguing that such a radical reenvisioning of God must be tempered and given meaning through reentering and reaffirming onto-theology in a qualified (hermeneutical) sense, I sketch a possible renewal of meaning for the traditional Christian parousia -concept as a hermeneutical circle between Hegel's systematic closure of Western metaphysics and Heidegger's deconstructive appropriation of the hidden possibilities of presence within the onto-theological tradition.
