Differentiated Citizenship and Contextualized Morality

Political theorists, increasingly, are realizing the virtues of contextuality to conceptual analysis. Just as theory may provide useful standards for the assessment of political practices, so may application of theoretical constructs within particular contexts provide a critical corrective to theory. This essay relates work undertaken within sociolegal studies applying a constitutive methodology to such efforts to contextualize political theorizing. The essay describes how the emphasis placed by constitutive theory on locality and meaning entails a contextual analysis. The essay then demonstrates how a constitutive and contextual approach can enhance our understanding of the moral issues surrounding differentiated citizenship policy. While the most obvious cost associated with differentiated citizenship policy is a loss in formal equality, a contextual assessment demonstrates the prospect of an even deeper, though ultimately contingent, moral loss in self-invention.     

Healthy and chronically‐ill children's generalisation of illness to biological and non‐biological categories

Using children's naïve theory of biology as a framework, this study investigated children's developing understanding of illness by examining their generalisation of illness to biological and non‐biological categories. In addition to differences associated with age, the children's health status was investigated for any possible linkwith their understanding. Healthy and chronically‐ill children, aged 4–11 years, were randomly assigned to one of three conditions, according to which exemplar (child, dog or duck) was described as suffering from an imaginary illness. Using a card‐sorting technique, the children assessed whether each entity out of 30 entities (five representatives in each of six categories: humans, mammals, non‐mammals, birds, plants and artifacts) could be afflicted by that illness. The children's generalisations indicated a grasp of the distinctiveness of the various categories, although they seemed less certain about the biological status of plants. Furthermore, the type of exemplar on which the children had been taught influenced their responses. However, the children's reasoning appeared unaffected by their health status and largely unaffected by age or gender. Copyright © 2004 John Wiley & Sons, Ltd.     

学前儿童朴素生物学理论及其获得机制

学前儿童朴素生物学理论发展的研究近20年来一直是儿童认知发展研究的热点。Carey等主张学前儿童的生物概念系统是从心理概念系统中分离出来的由一个系统到另一个系统的根本性概念转变,儿童还没有一个包含动植物的整合的生物系统。但另一些研究主张学前儿童能够对生物现象进行本体区分并形成内在一致的生物学因果解释,拥有朴素生物学理论,该理论是在一个概念系统（生物学概念系统）中逐渐的连续性变化过程。目前整合的观点认为儿童朴素生物学理论在童年早期就独立于心理学理论,但在分离一开始的一段时间里还要受心理学的影响。     

The influence of relational complexity and strategy selection on children's reasoning in the Latin Square Task

The present study focused on children's deductive reasoning when performing the Latin Square Task, an experimental task designed to explore the influence of relational complexity. Building on Birney, Halford, and Andrew's (2006) research, we created a version of the task that minimized nonrelational factors and introduced new categories of items. The results of two experiments conducted with school-aged children yielded an apparent dilution of complexity effects and suggest that specific inferential strategies can reduce the relational complexity that children need to process. A theoretical account is proposed emphasizing the influence of adaptive selection of strategies that mediate processing capacity constraints in reasoning development.     

The mediating and moderating effects of differentiation of self on body mass index and depressive symptomatology among an American college sample

Differentiation of self – a core construct of Bowen's (Bowen, M. (1978). Family therapy in clinical practice. New York: Jason Aronson) family systems theory – was examined as a possible predictor of psychological health and physical health and as a mediator and moderator of the relation between overall functioning and psychological health and physical health. A total of 818 American college students participated (mean age?=?23.72, SD?=?4.79) in this study. Differentiation of self was correlated and was predictive of psychological health, as measured by the Beck depression inventory, and physical health, as measured by body mass index (BMI). A multivariate multiple regression model revealed that differentiation of self partially mediated the effects of overall functioning on depressive symptomatology and on BMI. Results from a hierarchical regression model showed that differentiation of self moderated the relation between overall functioning and depressive symptomatology but did not moderate the relation between overall functioning and BMI. Taken together, these preliminary findings provide initial evidence of the importance of the associations between family systemic factors (differentiation of self) and psychological and physical health factors among American college populations.     

A phase transition model for the speed-accuracy trade-off in response time experiments

Most models of response time (RT) in elementary cognitive tasks implicitly assume that the speed-accuracy trade-off is continuous: When payoffs or instructions gradually increase the level of speed stress, people are assumed to gradually sacrifice response accuracy in exchange for gradual increases in response speed. This trade-off presumably operates over the entire range from accurate but slow responding to fast but chance-level responding (i.e., guessing). In this article, we challenge the assumption of continuity and propose a phase transition model for RTs and accuracy. Analogous to the fast guess model (Ollman, 1966), our model postulates two modes of processing: a guess mode and a stimulus-controlled mode. From catastrophe theory, we derive two important predictions that allow us to test our model against the fast guess model and against the popular class of sequential sampling models. The first prediction--hysteresis in the transitions between guessing and stimulus-controlled behavior--was confirmed in an experiment that gradually changed the reward for speed versus accuracy. The second prediction--bimodal RT distributions--was confirmed in an experiment that required participants to respond in a way that is intermediate between guessing and accurate responding.     

A general mechanism for linking personality traits to affect, motivation, and action

This article describes a general mechanism for linking personality traits to affect, motivation, and action. It is hypothesized that personality traits confer a propensity to perceive convergences and divergences between our belief that we can attain certain goals and the importance that we place on these goals (belief-importance or belimp theory). Belief and importance are conceptualized as two coordinates, together defining the belimp plane. Four distinct quadrants can be identified within the belimp plane (Hubris, Motivation, Depression, and Apathy), broadly corresponding to the personality dimensions of trait emotional intelligence, conscientiousness, neuroticism, and introversion. Strategies and requirements for testing belimp theory are presented as are a number of important theoretical and practical advantages that it can potentially offer.     

从系统论分析慢性炎症向肿瘤的恶性转化

慢性炎症相关肿瘤疾病,其机制涉及到的不再是个别的基因产物或蛋白分子,也不再是单一的信号通路或代谢途径,而是众多的基因、蛋白质和代谢小分子等各种生物分子构成的复杂的调控网络。这一网络中的相互联系、动态以及突变特性,要求运用系统论的方法来分析。这种分析将拓展临床医生的研究思路,推动对炎症向肿瘤转化本质的认识。
