Bayesian estimation of a multilevel IRT model using gibbs sampling

In this article, a two-level regression model is imposed on the ability parameters in an item response theory (IRT) model. The advantage of using latent rather than observed scores as dependent variables of a multilevel model is that it offers the possibility of separating the influence of item difficulty and ability level and modeling response variation and measurement error. Another advantage is that, contrary to observed scores, latent scores are test-independent, which offers the possibility of using results from different tests in one analysis where the parameters of the IRT model and the multilevel model can be concurrently estimated. The two-parameter normal ogive model is used for the IRT measurement model. It will be shown that the parameters of the two-parameter normal ogive model and the multilevel model can be estimated in a Bayesian framework using Gibbs sampling. Examples using simulated and real data are given.     

Li Zehou and Moritz Schlick on the Roots of Beauty

Beginning from the Enlightenment view that beauty or art is ＂useless,＂ the attempts to explain how aesthetic experience and judgment are possible presented by Moritz Schlick and Li Zehou are examined, compared and contrasted. The paper treats three main subjects, the anthropological origins of beauty, the origins of aesthetic judgments and the problem of the purpose or function of beauty or aesthetic experience. In the first--the historical-causal roots of beauty--the problem discussed is how to account for aesthetics in light of the practical needs and pursuits of human beings. For Schlick, the problem is couched in terms of how aesthetic experience can be made consistent with natural selection. The second main subject-the philosophical roots of beauty-is a discussion of the origin in the sense of justification of aesthetic judgments. And the third examines the problem of assigning some purpose to aesthetic feelings and attitudes. An apparent contrast is made, and perhaps resolved, between the respective views of Schlick and Li.     

职业使命感与免费师范生学业投入的影响：基于社会认知职业理论的视角

本研究以436名师范生为研究对象,采取社会认知职业理论（SCCT）为理论分析视角探讨了职业使命感对大学生学业投入的影响及其内在机制。结果表明：（1）职业使命感可以显著提高师范生的学业投入度;（2）职业结果期待和职业自我效能在职业使命感与学业投入之间起到部分中介作用;（3）职业使命感还可以通过职业结果期待、职业自我效能影响职业满意度,进而影响大学生的学业投入。最后,本研究对实践意义和研究局限进行了讨论。     

免费师范生的成就动机与职业兴趣相关研究

该研究以陕西师范大学的1349名大学生为样本,将成就动机的三个因素和职业兴趣六个因素综合起来加以考察,以揭示免费师范生的成就动机与职业兴趣之间的内在关系。结果表明：（1）免费师范生的成就动机水平低于大学生平均水平。非免费师范生的避免动机水平依次高于免费师范生和非师范生。（2）免费师范生的成就动机存在专业差异,职业兴趣存在性别和专业显著。（3）免费师范生的追求成功动机与职业兴趣的六个类型呈正相关,避免失败的动机与探索型、社会型和管理型星负相关。回归分析发现,追求成功和合成动机能够正向的预测社会型的职业兴趣。     

Plural Action Sentences and Logical Form: Reply to Himmelreich

This paper replies to Himmelreich's ‘The Paraphrase Argument Against Collective Actions’ [2017], which presents three putative counterexamples to the multiple agents analysis of plural action sentences. The paper shows that the argument from the first example, the discursive dilemma, fails because it relies crucially on a simplification of the target analysis, and that the others don't bear on the question because they turn out on examination to be about individual rather than group action sentences.     

John Calvin on the Christian's Social Responsibility: Cultural Activist or “Modest Social Reformer”?

Recently there have been heated discussions between Reformed theologians who embrace the two‐kingdoms doctrine and proponents of the Neo‐Calvinist tradition on whether Calvin held social transformationist views. This article examines the debate and argues that Calvin did not interpret the kingdom as a progressive social‐transforming reality that gradually establishes God's future eschatological reign on earth. Instead, he regarded Christ's present reign as a “backward”‐reaching reality that restores God's original created order. At the same time Calvin did not make a sharp categorical distinction between the spiritual and civil realms but depicted the civil and spiritual order as two regiments of God's one reign that mutually aid and assist each other.     

On Hare's attempt to bridge the Kantian-consequentialist gap: A response to Forschler's rejoinder

In a paper in this journal (Wall 2016), the author of the present paper critiqued Scott Forschler's attempt (2013) to establish that Jens Timmermann's argument (2005) against R. M. Hare's attempt (1981) to bridge the Kantian-consequentialist gap is unsuccessful. Forschler's thesis is that Hare's utilitarianism is strictly normative, not metaethical. In Hare's ethical rationalism, which is metaethical but contains no intrinsic ends (Forschler 2013), reason determines the proper ends, and preference satisfaction has no value prior to reason's determinations (Forschler 2013). The present author responded that Hare's moral approach presupposes that preference satisfaction is the ultimate end (Wall 2016) and that an analysis of preference satisfaction in Hare's moral approach cannot be confined to normative ethics. Forschler's rejoinder (2017) suggests that Hare's moral theory was misinterpreted by the author, who now shows that such a judgment results from significant oversights concerning the foundation of Hare's moral theory and utilitarian foundations.     

Neuropsychological test norms controlled for physical health: Does it matter?

The objective of the present study was to investigate the effects of physical health on neuropsychological test norms. Medical and neuropsychological data from 118 healthy volunteer controls, aged 26–91 years, were collected during five recruitment occasions. The examinations included a clinical investigation, brain neuroimaging, and a comprehensive neuropsychological test battery. Test‐specific statistical regression‐weights for age, education and gender were calculated to establish preliminary test norms. Hierarchical regression analyses demonstrated that control in addition for physical health moved best performance from age 60 to 65 for abstraction; replaced a plateau above age 70 for verbal fluency, with a continued rise in performance; eliminated significant negative influences of age on auditory learning, spatial reasoning and complex copying; reduced them on wordlist recall, psychomotor speed, visual scanning and mental shifting; and slightly reduced negative influences of low education on most verbal tests, several memory tests, and psychomotor speed, indicating rises in normative scores of up to 0.8 SD at age 80 and 0.4 SD at age 60. No differences were found at age 40. Although the sample size is not adequate to be used for normative data, the findings indicate that norms uncontrolled for health overestimate the negative influence of advanced age and low education, implying a risk of drawing false diagnostic conclusions.     

Change and Management of Complex Services: The Ethno-narrative Form to Support Good Living and Working Together

Nowadays, managing change in complex services requires that middle management re-designs its objects and professional practices, in order to cope with new needs. It seems therefore crucial to activate training settings that allow managers to: (1) develop research and analytical skills on their own work practices and professional objects; (2) face and manage conflict, related to every change, that represents an opportunity to reflect and review one's own practices; and (3) build new and shared repertories of managerial practices, able to support a better form of living and working together within the management community. Moving from these hypotheses, inside the setting of a training intervention conducted in an educational service, the article discusses a specific tool used to generate opportunity of exchange, and reflection, within a challenging framework of change.     

Eye Movements in Strategic Choice

In risky and other multiattribute choices, the process of choosing is well described by random walk or drift diffusion models in which evidence is accumulated over time to threshold. In strategic choices, level‐k and cognitive hierarchy models have been offered as accounts of the choice process, in which people simulate the choice processes of their opponents or partners. We recorded the eye movements in 2 × 2 symmetric games including dominance‐solvable games like prisoner's dilemma and asymmetric coordination games like stag hunt and hawk–dove. The evidence was most consistent with the accumulation of payoff differences over time: we found longer duration choices with more fixations when payoffs differences were more finely balanced, an emerging bias to gaze more at the payoffs for the action ultimately chosen, and that a simple count of transitions between payoffs—whether or not the comparison is strategically informative—was strongly associated with the final choice. The accumulator models do account for these strategic choice process measures, but the level‐k and cognitive hierarchy models do not. © 2015 The Authors.
