Rule following and rule use in the balance-scale task

Quinlan et al. [Quinlan, p., van der Mass, H., Jansen, B., Booij, O., & Rendell, M. (this issue). Re-thinking stages of cognitive development: An appraisal of connectionist models of the balance scale task. Cognition, doi:10.1016/j.cognition.2006.02.004] use Latent Class Analysis (LCA) to criticize a connectionist model of development on the balance-scale task, arguing that LCA shows that this model fails to capture a torque rule and exhibits rules that children do not. In this rejoinder we focus on the latter problem, noting the tendency of LCA to find small, unreliable, and difficult-to-interpret classes. This tendency is documented in network and synthetic simulations and in psychological research, and statistical reasons for finding such unreliable classes are discussed. We recommend that LCA should be used with care, and argue that its small and unreliable classes should be discounted. Further, we note that a preoccupation with diagnosing rules ignores important phenomena that rules do not account for. Finally, we conjecture that simple extensions of the network model should be able to achieve torque-rule performance.     

FINITE MODELS CONSTRUCTED FROM CANONICAL FORMULAS

This paper obtains the weak completeness and decidability results for standard systems of modal logic using models built from formulas themselves. This line of work began with Fine (Notre Dame J. Form. Log. 16:229–237, 1975). There are two ways in which our work advances on that paper: First, the definition of our models is mainly based on the relation Kozen and Parikh used in their proof of the completeness of PDL, see (Theor. Comp. Sci. 113–118, 1981). The point is to develop a general model-construction method based on this definition. We do this and thereby obtain the completeness of most of the standard modal systems, and in addition apply the method to some other systems of interest. None of the results use filtration, but in our final section we explore the connection.     

知道一个行动的逻辑(英文)

以活动为认知对象的逻辑还没有系统地建立。本文我们采用半无穷方法、自代入方法、固定点方法和拟赋值方法全面建立这样的逻辑,从而研究知道一个活动的各种逻辑特性。根据这些方法,我们分别提出四类刻画知道一个活动的逻辑系统和相应的语义,然后证明这些系统相对各自的语义是可靠和完全的。     

COLLECTIVE SELF‐ORGANIZATION IN GENERAL BIOLOGY: GILLES DELEUZE,CHARLES S. PEIRCE,AND STUART KAUFFMAN

Stuart Kauffman's proposal in Investigations to ground a “general biology” in the laws of self‐organization governing systems of autonomous agents runs up against the methodological problem of how to integrate formal mathematical with semantic and semiotic approaches to the study of evolutionary development. Gilles Deleuze's concept of the virtual and C. S. Peirce's system of existential graphs provide a theoretical framework and practical art for answering this problem of method by modeling the creative event of collective self‐organization as both represented and practiced in the scientific community.     

MAKING SPACE FOR THE METHODOLOGICAL MOSAIC: THE FUTURE OF THE FIELD OF SCIENCE-AND-RELIGION

This article is a response to Josh Reeves's recent book Against Methodology in Science and Religion: Recent Debates on Rationality and Theology that welcomes Reeves's proposal for an anti-essentialist future for the field of science-and-religion, particularly because it has the potential to move the field beyond current, well-worn methods: the dominance of Christian theology and doctrine, the importance of credibility strategies, and the dependence upon philosophical discourses. Reeves’ proposal has the potential to open the science-and-religion field to other topics, problems, and methods, such as studying lived science-and-religion. One way of doing this is to study popular culture and its artifacts such as literature, which portrays a co-mingling of religion and science at the level of day-to-day experiences and practices of characters. For at the level of lived experience, religion and science are not well-defined disciplines neatly compartmentalized into separate academic departments.     

The Philosophical Role of Illness

This article examines the philosophical role of illness. It briefly surveys the philosophical role accorded to illness in the history of philosophy and explains why illness merits such a role. It suggests that illness modifies, and thus sheds light on, normal experience, revealing its ordinary and therefore overlooked structure. Illness also provides an opportunity for reflection by performing a kind of suspension (epoché) of previously held beliefs, including tacit beliefs. The article argues that these characteristics warrant a philosophical role for illness. While the performance of most philosophical procedures is volitional and theoretical, however, illness is uninvited and threatening, throwing the ill person into anxiety and uncertainty. As such it can be viewed as a radical philosophical motivation that can profoundly alter our outlook. The article suggests that illness can change the ways in which we philosophise: it may shape philosophical methods and concerns and change one's sense of salience and conception of philosophy.     

Three Approaches to Doing Philosophy: a Proposal for Grouping Philosophical Exercises in Classroom Teaching

Classroom teaching has two aims: learning philosophy, that is, the great philosophers, and doing philosophy. This article provides an overview of thirty exercises that can be used for doing philosophy, grouped into three approaches. The first approach, doing philosophy as connective truth finding or communicative action, is related to such philosophers as Dewey and Arendt, and is illustrated by the Socratic method. The second, doing philosophy as test‐based truth finding, is related to such philosophers as Popper, and is illustrated by Community of Philosophical Inquiry. The third, doing philosophy as juridical debate, judging truth‐value and making judgment, is related to such philosophers as Foucault, and is illustrated by philosophical debate. The analysis shows that although the classical methods applied by the great philosophers appear to be missing from classroom exercises, they do, in fact, remain at the heart of the matter.     

骨外固定——微创肢体重建的利器

骨外固定以其独特的环形、铰链和螺杆等的简单构型,用于复杂创伤及创伤后遗症,复杂的肢体畸形的治疗,可以获得其他方法不可比拟的效果,堪称肢体重建的一把利器.本文从以胫腓骨中段的短斜型闭合骨折为例,详细阐述了外固定器治疗骨折的优势.以复杂的足踝畸形病例为例,阐释了以Ilizarov技术为代表的骨外固定用于肢体畸形矫正并创造神奇效果的秘密.骨外固定顺应了肢体损伤、肢体畸形发生发展的客观规律,由外而内,提供一个适宜的重建方向,符合生物学要求,可以实现骨与软组织的自然修复与重建.     

尿沉渣法、干化学法及传统镜检测定尿液中有形成分的对比研究

以传统镜检法结果作为标准,分别采用AX4280全自动尿液干化学法分析仪（干化学法）和IQ200尿沉渣分析仪（尿沉渣法）及两种方法的并联和串联检测新疆石河子地区532例患者的清洁中段尿,并评价两种方法的检测效果。结果显示,与传统镜检法比较,干化学法和尿沉渣法串联对尿液中红、白细胞检出率的阳性预测值高,具有临床意义;尿沉渣法对红、白细胞检测误诊率较高,需用镜检进行确认。尿沉渣法和干化学法可对临床提供一定的依据,但不能完全代替传统镜检,几种方法可作为互补,提高检测准确性。
