Early childhood development in Africa: interrogating constraints of prevailing knowledge bases

The past two decades have been characterized by renewed attention to the importance of early childhood development (ECD) policies and services in the world's richest and most industrialized countries. During the same period, we have witnessed unprecedented efforts to place ECD policies on the national development planning agenda of the economically less advantaged countries of the Majority World. This paper is premised on the concern that the purposes that have led bilateral and multilateral international agencies to promote and support ECD services in Africa may also be paving the way for uncritical adoption of program and service delivery models grounded in value systems and knowledge bases that may not be appropriate for the continent. We present two critiques to highlight the dangers of ignoring the sociocultural contexts of the knowledge bases that inform ECD policies and practices. We describe one capacity-building effort, under the auspices of the Early Childhood Development Virtual University (ECDVU), to promote culturally relevant knowledge and prepare leadership personnel for Africa's emerging ECD movement. Finally, based on an exercise designed for an ECDVU cohort to engage and reflect on critiques of mainstream research and theorizing on child development, we share insights that are suggestive of the ways in which African perspectives can contribute to and enrich a global knowledge base on child development.     

Effects of verbal working memory and cumulative linguistic knowledge on reading comprehension1

Abstract: In the present study, the effects of verbal working memory (VWM) and cumulative linguistic knowledge (CLK) on reading comprehension were investigated using an individual difference approach. We examined whether VWM and CLK are distinct verbal factors and whether each has independent influences on reading comprehension. VWM was tested using the Japanese Reading Span Test (RST). CLK was assessed using information, vocabulary, and similarity subtests of the Wechsler Adult Intelligence Scale‐Revised (WAIS‐R), as well as with the Hyakurakan kanji reading test. The differences between VWM and CLK were examined using correlation analyses between reading comprehension scores, and digit forward and backward span scores. The results showed that VWM and CLK were independent of each other, and that VWM and CLK independently contributed to reading comprehension. The obtained correlations also showed that CLK was independent of any type of short‐term memory, and that the VWM measured using the RST had little correlation with digit span.     

Epistemic luck and the generality problem

Epistemic luck has been the focus of much discussion recently. Perhaps the most general knowledge-precluding type is veritic luck, where a belief is true but might easily have been false. Veritic luck has two sources, and so eliminating it requires two distinct conditions for a theory of knowledge. I argue that, when one sets out those conditions properly, a solution to the generality problem for reliabilism emerges.

Common knowledge of payoff uncertainty in games

Using epistemic logic, we provide a non-probabilistic way to formalise payoff uncertainty, that is, statements such as ‘player i has approximate knowledge about the utility functions of player j.’ We show that on the basis of this formalisation common knowledge of payoff uncertainty and rationality (in the sense of excluding weakly dominated strategies, due to Dekel and Fudenberg (1990)) characterises a new solution concept we have called ‘mixed iterated strict weak dominance.’     

RATS,We Should Have Used Clinton: Subliminal Priming in Political Campaigns

Political strategists decide daily how to market their candidates. Growing recognition of the importance of implicit processes (processes occurring outside of awareness) suggests limitations to focus groups and polling, which rely on conscious self‐report. Two experiments, inspired by national political campaigns, employed Internet‐presented subliminal primes to study evaluations of politicians. In Experiment 1, the subliminal word “RATS” increased negative ratings of an unknown politician. In Experiment 2, conducted during former California Governor Gray Davis's recall referendum, a subliminal photo of Clinton affected ratings of Davis, primarily among Independents. Results showed that subliminal stimuli can affect ratings of well‐known as well as unknown politicians. Further, subliminal studies can be conducted in a mass media outlet (the Internet) in real time and supplement voter self‐report, supporting the potential utility of implicit measures for campaign decision making.     

直觉对内隐学习优势效应的特异性贡献

已有人工语法的内隐学习研究中一个关键的问题是被试在不同指导语诱发下究竟形成了什么样的知识表征？实验借助结构知识的测量方式, 采用记忆和规则探索两种指导语, 考察了两组被试所获得的深层知识表征(结构知识)。结果发现：(1)在记忆指导语条件下, 被试获得了语法规则; (2)直觉在记忆指导语条件下贡献突出, 表现出特异性。该结果表明记忆指导语引发了被试基于直觉区分人工语法规则的内隐学习优势效应。     

工作设计对知识型员工和体力工作者的差异化影响：一个现场准实验研究

虽然泰勒主义似乎已被工作设计所替代, 但是近来有些学者们注意到工作设计并未起到预期的效果。该研究旨在探讨工作类型作为一个重要的调节变量, 影响着这两种观点的适用性。通过一个纵向现场准实验设计研究, 结果证实了工作类型的调节作用, 即工作丰富化对知识型员工和体力工作者工作产出的影响存在显著差异。这一结果表明, 泰勒主义和工作设计思想并无优劣之分。该文的研究结果对人力资源管理实践的发展, 具有一定的现实指导意义。     

计算机化自适应测验在认知诊断中的应用

作为认知诊断与计算机化自适应测验相结合的产物, 认知诊断计算机化自适应测验(Cognitive Diagnostic Computerized Adaptive Testing, CD-CAT)是对被试知识状态的自适应。它既有传统CAT所面临的普遍性问题, 也有在认知诊断中遇到的特殊问题：由于认知诊断中涉及属性这一概念, CD-CAT与传统CAT有很大的差别。本文紧紧围绕属性引起的差异, 分别从认知诊断模型、题库建设、起始规则、选题策略、被试知识状态估计和终止规则等几部分详细介绍CD-CAT的研究进展和存在的问题。     

The Knowledge Argument against Physicalism: Its Proponents and Its Opponents

The knowledge argument usually takes the form of a thought experiment where the subject, having some psychological deficiency, lacks any introspective data to derive the knowledge of her experience. Most defenders of the knowledge argument see the argument as both a support of dualism and an objection to any full-blooded form of physicalism. However, this paper argues that the knowledge argument against physicalism may be directed, in an exactly parallel form, against reductive dualism; moreover, although most physicalists who are the opponents of the knowledge argument do not give any convincing response to the knowledge argument, some kinds of physicalism can live with the knowledge argument.     

Slavoj Žižek and the Real Subject of Politics

Slavoj ?i?ek's refusal to sketch an alternative to the global liberal-capitalist order, combined with his claim that there is an urgent need for a repolitization of, most of all, the economy, raises the question of the possibility of radical political thought and action. Considering fundamentalisms and politically correct multiculturalism not as oppositional, but as correlative to the “depolitization” of post-modern societies, ?i?ek invokes the emancipatory legacy of Europe in an attempt to reinvent Marxism in a way similar to what Lenin, thrown into an open situation, had to do in 1917 between the revolutions. A single question confronts political philosophy today: is liberal-capitalist democracy the ultimate horizon of our political practice, or is it possible to open up the space for another political articulation? The key to a repolitization is to identify with the “symptom” of the existing global order's false claim to Universality, with the excluded “part of no part” who politicizes it's predicament by claiming to stand for the real universal. In order not to discard political struggle as “unrealistic”, today's cynical “realist” consensus must be broken. Taking things as they “really are” has become the dominant ideological mode that keeps people from thinking about alternatives. The remedy is to show that things never are “really” as they are.
