Reactive cognition, reactive emotion: Toward a more psychologically-informed understanding of reactive homicide.

[Correction Notice: An erratum for this article was reported in Vol 15(2) of Psychology, Public Policy, and Law (see record 2009-08329-001). Due to a production error, this article was published with incorrect footnote numbering. Specifically, the intended footnotes 2 through 9 were moved to the end, and footnote 10 became footnote 2 and so forth.] Recent scholarship has drawn attention to the alternative contributions of dysfunctional reactive cognition (e.g., provocation interpretational bias) and emotion (e.g., provoked fury) in heat-of-passion killings. Two main theses have been advanced. First, there exists a meaningful parallel between the instrumental-reactive aggression dichotomy in psychology and murder-manslaughter distinction in law. Second, analysis of this parallel suggests that the heat-of-passion (or provocation) defense disproportionately favors emotional over cognitive dysfunction in mitigating murder to manslaughter. These theses, however, have yet to be fully developed and raise additional, critical questions that have not yet been addressed: Other than interpretational style, how may social-cognitive science inform our understanding of the role of cognitive bias in reactive homicide? How is serious interpretational bias related to alternative forms of psychiatric disorder as recognized in law? This article addresses these and related questions regarding the differential and interactive contributions of dysfunctional cognition and emotion in the execution of reactive homicide.

高气液比垂直两相管流流型判别研究

在多相管流中,流型判断准确与否决定着压降计算的精度,根据流型来选择相应的压降计算公式,能提高压降结果的准确性。目前,在现场所遇到的绝大多数多相流问题是气一液(油、气),气一液一液(油、气、水)形式的多相流。本文以气一液两相流为主,着重讨论其流型的划分和判断。并模拟高气液比环境进行了一组室内实验,应用Beggs-Brill、Aziz-Govier、Kaya、Zhmx4种模型分别对室内实验流动形态进行了判断,结果表明Kaya和Zhmx模型对高气液比垂直管流的流型判断比较准确。     

一种基于场景区分算法的背景抽取方法

视频监控面对的场景具有静态的成分和缓变的成分.为了从视频流中稳定地抽取较精确的背景,提出了一种基于场景区分的背景抽取算法.首先通过混合高斯模型对视频序列中稳定的成分进行建模,然后采用Kalman滤波模型对视频序列中变化的成分进行建模,最后采用场景的区分算法将2种模型结果进行处理从而得到背景.实验结果表明:该方法能从视频...     

构建和谐城市——青岛城市南北势差的形成及应对分析

青岛是德国人开发和建设的殖民城市,建设之初已呈现南北不同的布局特点。德国人撤离之后青岛继续完善、扩展,形成了北工南宿的带状格局,南北差距不断加大。这一状况大大阻碍了城市的和谐发展。其间几次迁移市中心的设想和实践都未能改变这一局面。近年出台了许多措施,整治北部区域,以此来缩小南北差距。以青岛城市发展为例强调了综合平衡发展对于构建和谐城市的重要意义。     

钢带简支梁自振特性测定试验研究

介绍了模态计算方法和基本原理，通过多点激振、单点拾振的方法进行了钢带简支梁自振试验测定了梁的模态，利用模态理论计算得出该简支梁的模态，从理论解析解和有限元分析来看，试验结果与理论分析结果吻合比较好。     

略论传统中、西方绘画的主要区别

传统中、西方绘画,由于受世界各民族、各国家政治经济、宗教哲学、文化传统和艺术观念、审美情趣等因素的影响,使得传统中、西方绘画形成了各自不同的特点。     

一种基于变精度粗糙集的图像分类方法

基于变精度粗糙集,引入近似区分矩阵的概念,提出一种基于颜色特征的图像分类模型及其分类算法.变精度粗糙集理论在数据分类应用中主要是将集合间精确的包含关系改为多数包含关系,既允许一定程度的错误分辨率存在.用该方法进行图像资源的分类,克服了经典粗糙集不宜处理带有噪声的数据和决策表不协调的分类问题的缺陷,同时又大大简化分类规则,且形成的规则集便于用户理解.完善近似空间的概念.实验结果表明：在处理决策表不协调的图像分类问题,变精度粗糙集方法性能良好,分类准确、高效.     

On the spuriousness of the symbolic/subsymbolic distinction

The article criticises the attempt to establish connectionism as an alternative theory of human cognitive architecture through the introduction of thesymbolic/subsymbolic distinction (Smolensky, 1988). The reasons for the introduction of this distinction are discussed and found to be unconvincing. It is shown that thebrittleness problem has been solved for a large class ofsymbolic learning systems, e.g. the class oftop-down induction of decision-trees (TDIDT) learning systems. Also, the process of articulating expert knowledge in rules seems quite practical for many important domains, including common sense knowledge.The article discusses several experimental comparisons betweenTDIDT systems and artificial neural networks using the error backpropagation algorithm (ANNs usingBP). The properties of one of theTDIDT systemsID3 (Quinlan, 1986a) are examined in detail. It is argued that the differences in performance betweenANNs usingBP andTDIDT systems reflect slightly different inductive biases but are not systematic; these differences do not support the view that symbolic and subsymbolic systems are fundamentally incompatible. It is concluded, that thesymbolic/subsymbolic distinction is spurious. It cannot establish connectionism as an alternative cognitive architecture.
