Minimizing the number of observations: A generalization of the spearman-brown formula

A new method for determining the minimum number of observations per subject needed to achieve a specific generalizability coefficient is presented. This method, which consists of a branch-and-bound algorithm, allows for the employment of constraints specified by the investigator.     

Legal and Philosophical Fictions: At the Line Where the Two Become One

Anti-foundationalism is a central topic in recent legal scholarship. The critical legal studies movement (CLS) has mounted a strong challenge to the traditional belief that legal materials (constitutions, statutes, and precedents) determine legal outcomes and constrain judicial decision making. This scholarship has overlooked, however, the degree to which the debate between traditional legal determinacy and anti-foundational indeterminacy is yet another manifestation of a continuous debate in Western thought – one that has its roots in pre-Socratic rhetoric and philosophy.This paper traces the indeterminacy thesis back to the contest of ideas between Protagoras and Plato. I examine two well-known and elated Protagorean notions: first, that two arguments (logoi) are always set in opposition to one another with regard to every matter and, second, that the rhetorician can always make the weaker argument the stronger. I contend that taking these Protagorean notions seriously – perhaps even more seriously than self-avowed anti-foundationalists customarily do – leads paradoxically to a modified endorsement of foundationalism that is nevertheless wholly consistent with the Protagorean project. Calling upon texts by Aristotle, Seneca and René Girard, I focus upon how fictionality in representations of Platonically conceived Truth reveals a binarization in thought that is simultaneously untenable and unavoidable.     

Humanizing education: Subjective and objective aspects

I propose that there are four standards to be met if a given educational enterprise is to be considered humane: (1) the practice to be mastered must be socially justified; (2) the disciplines pursued to master the practice must be appropriate to the practice; (3) the practice must be owned by the learner; and (4) this ownership must itself meet certain ethical requirements. The paper emphasizes the problem of ownership. It argues for a view of ownership that is communitarian. This view sees ownership as a function of identification or membership. People become committed to certain educational ends in virtue of the fact that they see themselves as members of a group and the ends as the ends of the group. It is central to this view that ownership of ends does not require full understanding or rational appraisal of such ends. I argue that a rational appraisal of ends is difficult when a novice seeks to appraise the ends of some practice both because the ends of the practice are internal to it in a way that makes grasping such ends difficult prior to mastery of the practice and because initiation into the practice will change the individual's standards of appraisal.     

语法的进化连续性及进化起源解释

语法是人类交流系统有别于其他动物的关键特征之一。行为比较研究表明, 除人类外的其他灵长目动物也能理解并掌握抽象的顺序排序规则; 神经生物学比较研究表明, 支持排序处理的神经机制来自人类与其他灵长目动物共同具有的脑区。因此语法所依赖的序列学习能力在人类与其他灵长目动物间具有进化连续性。词汇限制假说、事件感知假说与自我驯化假说分别从不同角度对人类语法的进化起源进行了解释。未来研究需要探讨人工语法任务中所发现的脑神经机制是否是层级结构加工的通用处理器, 并进一步澄清语义加工与语法加工的关系。     

Delineating the Structural Precursors and Cognitive Consequences of Personal Powerlessness: the Filipino Woman's Experience

Adopting a structural-cognitive perspective and path analysis, this study demonstrates that personal powerlessness generates sequelae of maladaptive cognitions, namely, low self-esteem, low success expectancies and a weak motivation for self-improvement. Despite adverse structural and natural forces, Bicolano women exhibited self-efficacy, high self-esteem, and strong propensity for self-improvement, albeit expressing low success expectancies. These constructive cognitions can be attributed to the women's strong achievement ethic, high educational attainment, and supportive kinship system. These factors also compensate for the depressive effects of low success expectancies on the motivation for self-improvement. Implications for empowerment strategies and cognitive literature are discussed.     

Belief in a Just World and Employee Voice Behavior: The Mediating Roles of Perceived Efficacy and Risk

Abstract

In this research, we hypothesized that employees’ belief in a just world (BJW) would be positively related to their voice behavior, i.e., the expression of ideas or opinions with the intention of engendering organizational improvement or change, and that this relation would be mediated by perceived voice efficacy and perceived voice risk. To test these hypotheses, we collected self-reported data from employees in two different countries: China (N?=?313) and Germany (N?=?190). The results revealed a positive association between BJW and employee voice behavior in both samples. The two-mediator model was confirmed in the Chinese sample, while only perceived voice efficacy played a mediating role in the German sample. Possible reasons for these differences may be related to differences in cultural dimensions and education levels between the samples. The findings emphasize the importance of bolstering employees’ belief in justice and the organizational climate, which influence perceived voice efficacy and risk, as means to increase organizational voice behavior.     

Frontal-Lobe Involvement in Spatial Memory: Evidence from PET,fMRI, and Lesion Studies

Many studies have identified the prefrontal cortex as the brain area that is critical for spatial memory, both in humans and in other primates. Other studies, however, have failed to establish this relation. Therefore, the aim of this paper was to review the literature regarding the role of the human prefrontal lobe in spatial memory. This was done by examining the evidence obtained from neuropsychological patients and from studies using brain-imaging techniques (PET and fMRI). Evidence supporting the notion that the prefrontal cortex is extensively involved in spatial working memory was found. The majority of these studies, however, suggests that frontal-lobe involvement is not related to the type of material that is being processed (e.g., spatial vs. nonspatial), but to process-specific functions, such as encoding and retrieval. Theoretically, these functions could be linked to the central executive within Baddeley's working-memory model, or to recent theories that emphasize the various processes that play a role in working memory. Also, methodological issues were discussed. Further research is needed to enhance our understanding of the precise interaction of domain-specific and general processes.     

Studies of Work: Achieving Hybrid Disciplines in IT Design and Management Studies

We explore the relationship between ethnomethodology (EM), ethnography and the needs of managers and designers in industry, considering both ethnomethodological and industrial criteria of adequacy and explicating their relationship through the concept of “audience.” We examine a range of studies in this light, with a view to their possible candidacy as hybrid studies and identify three types of application of EM studies of work: market research, design, and business improvement. Application in the first of these fields we dub “anthropological,” in that it consists in studying and reporting back on the ways of exotic people (customers). This is the application most commonly found in studies of computer supported co-operative work (CSCW). A second CSCW application, “technomethodology,” involves the introduction of EM concepts into the design process. A further application, dubbed “holding-up-a-mirror,” involves reporting back to members of a setting upon their own activities. We argue that technomethodology and holding-up-a-mirror both offer the possibility of creating hybrid disciplines. We consider the objection that improvement and design involve the introduction of value judgements that threaten the practice of EM indifference, arguing that action research can serve as a guarantee of unique adequacy (UA) by testing the researcher’s understanding as analysis in action in the setting. Furthermore, the standard of reporting required by the UA criterion contributes to the effectiveness of proposed solutions.     

A Meta-Analysis of Cognitive Deficits in Adults with a Diagnosis of Schizophrenia

This review identified 1275 studies examining cognitive deficits in people with schizophrenia, published between 1990 and 2003. Data from 113 studies (4365 patients and 3429 controls) were combined in a meta-analysis carried out on the five cognitive domains of IQ, memory, language, executive function, and attention. Studies were excluded where they lacked a suitable control group or failed to present complete information. In all five cognitive domains, analysis indicated a consistent trend for patients to perform more poorly than healthy controls, with significant heterogeneity across studies. Sources of heterogeneity were analyzed and a need to ensure more appropriate composition of patient and control groups and to adopt a more refined and methodologically correct, hypothesis-driven approach was identified.
