Community and school choice: Geographies of care and responsibility

This paper draws on elements of critical discursive psychology in order to explore some of the issues and concerns raised by parents' responses to the policy and practice of school choice. Drawing on data from a group of mothers of diverse social class and racial backgrounds, this paper examines the dilemmas some mothers engage with in their role as chooser—reconciling competing rationalities for choosing or trying to manage contradictions. A central argument of this paper is that the policy and political context shaping the emergence of school choice in Britain has provisionally secured the development of certain trends in education—consumerism, individualism and competition. Alongside and coupled with this has been the veneration of a narrow utilitarian conception of parents as consumers of education services, defined as people who share the capacity and willingness to maximize the utility of their decisions in a rationally self‐interested way. This paper questions the value of this approach as a framing for understanding the aspirations, motivations and fantasies informing parents' school choice and highlights instead the ways in which some mothers articulate the importance of community in their decision‐making practices.

IMAGINATION'S GRIP ON SCIENCE

Abstract: In part because “imagination” is a slippery notion, its exact role in the production of scientific knowledge remains unclear. There is, however, one often explicit and deliberate use of imagination by scientists that can be (and has been) studied intensively by epistemologists and historians of science: thought experiments. The main goal of this article is to document the varieties of thought experimentation, not so much in terms of the different sciences in which they occur but rather in terms of the different functions they fulfil. I argue that thought experimentation (and hence imagination) plays a role not only in theory choice but in singular causal analysis and scientific discovery as well. I pinpoint, moreover, some of the rules governing the use of thought experiments in theory choice and in singular causal analysis, that is, some of the criteria they should meet in order to fulfil those functions successfully.     

FANTASY,FICTION, AND FEELINGS

Abstract: The nature of fantasy has been little discussed, despite its importance in the arts. Its significance is brought out here in relation to the long‐standing debate on the alleged paradox of fiction—that we respond emotionally to characters and events known to be unreal. Examination of the paradox shows it to be ill founded once the nature of fantasy is appreciated. Moreover, a detailed consideration of fantasy shows that it can itself provide a plausible account of our emotional reactions to creative literature, an account that, after a review of some possible objections, is then contrasted with the leading contemporary theories.     

印尼留学生汉语主动句被动句命题表征项目顺序

采用句子-图形验证任务初步探讨了不同汉语水平的印尼留学生理解汉语主动句、被动句所形成的命题表征中的项目顺序特点。结果表明,初级汉语水平印尼留学生理解汉语主动句、被动句后所建构的命题表征中项目顺序均为“受事→施事”;中级汉语水平印尼留学生理解汉语主动句所形成的命题表征项目顺序为“施事→受事”,而其理解汉语被动句所形成的命题表征项目顺序为“受事→施事”。母语主动句、被动句的理解特点影响印尼留学生汉语主动句、被动句命题表征项目顺序;这种影响作用与其汉语水平有一定的关系。     

想象对大学生内隐刻板印象的影响研究

通过对大学生在三种想象条件下性别-职业刻板印象的IAT的结果的对比进行实验。研究表明:反刻板印象想象策略的干预效果明显,刻板印象的内隐效应在明显地减弱;即使是大学生,在性别-职业刻板印象上也存在内隐效应,而且没有性别差异;内隐刻板印象具有一定的适应性,在内隐的和无意识的水平上反刻板印象想象无法完全消除刻板印象。     

Electrical stimulation of the pedunculopontine tegmental nucleus in freely moving awake rats: time- and site-specific effects on two-way active avoidance conditioning

The pedunculopontine tegmental nucleus (PPTg) is involved in the regulation of thalamocortical transmission and of several functions related to ventral and dorsal striatal circuits. Stimulation of the PPTg in anesthetized animals increases cortical arousal, cortical acetylcholine release, bursting activity of mesopontine dopaminergic cells, and striatal dopamine release. It was hypothetized that PPTg stimulation could improve learning by enhancing cortical arousal and optimizing the activity of striatal circuits. We tested whether electrical stimulation (ES) of the PPTg, applied to freely-moving awake rats previously implanted with a chronic electrode, would improve the acquisition and/or the retention of two-way active avoidance conditioning, and whether this effect would depend on the specific PPTg region stimulated (anterior vs posterior) and on the time of ES: just before (pre-training) or after (post-training) each of three training sessions. The treatment consisted of 20 min of ES (0.2 ms pulses at 100 Hz; current intensity: 40-80 microA). The results showed that (1) this stimulation did not induce either any signs of distress nor abnormal behaviors, apart from some motor stereotyped behaviors that disappeared when current intensity was lowered; (2) pre-training ES applied to the anterior PPTg improved the acquisition of two-way active avoidance, (3) no learning improvement was found after either post-training ES of the anterior PPTg, or pre- and post-training ES of the posterior PPTg. The results give support to a role of PPTg in learning-related processes, and point to the existence of functional PPTg regions.     

ALZHEIMER'S DISEASE AND SOCIALLY EXTENDED MENTATION

Abstract: The leading accounts of the ethics of proxy decision making implicitly draw on internalist conceptions of the philosophy of mind, or so this essay tries to demonstrate. Using the views of Ronald Dworkin as its jumping-off point, the essay argues that accepting the sort of externalism associated with writers such as Putnam and Burge would alter Dworkin's conclusions concerning how we should respond to the current or precedent decisions of people suffering from dementia. Building on the views of Agnieszka Jawarska, it argues that accepting "active" externalism à la Clark and Chambers would provide currently competent people with new resources for establishing the authority of their present values over inconsistent values they might come to entertain should they become demented.     

THE EFFECTS OF RESPONSE CARDS ON STUDENT AND TEACHER BEHAVIOR DURING VOCABULARY INSTRUCTION

The use of response cards during whole‐class English vocabulary instruction was evaluated. Five low‐participating students were observed during hand‐raising conditions and response‐card conditions to observe the effects of response cards on student responding and test scores and teacher questions and feedback. Responding and test scores were higher for all targeted students in the response‐card condition. The teacher asked a similar number of questions in both conditions; however, she provided more feedback in the response‐card condition.     

预搜索过滤分心物的机制

如果先呈现若干分心物,然后添加靶子与其他分心物,那么就会改善搜索——预搜索效应。对于过滤分心物的潜在机制,研究者相继提出了主动抑制说、突然呈现说与时间分离说等理论。这些理论都有其合理的一面,能解释一些特定的实验现象,但任何单一机制都无法解释所有的实验现象。文章提出,未来的研究应该整合已有的实验现象与理论,系统考察旧客体与新客体的作用,重点整合抑制说与突现说,它们可能是一个连续体的两端     

From Speechlessness to Presence

Spiritual direction, or the directed art of inner conversation, emerges from a psychological inflection in which we learn that radical inner otherness is the fuel of spirit. Spirit, manifesting between self and other incarnates through and in the subject, as well as through the other encountered as authentic subject. One individuates, then, by relating to the Self as a desiring subject. Moving in the direction of spirit, we push back dimension by dimension to get to one dimension. Eventually, we may encounter a numinous silence, an emptiness that is full.
