Fitting multivariage normal finite mixtures subject to structural equation modeling

This paper is about fitting multivariate normal mixture distributions subject to structural equation modeling. The general model comprises common factor and structural regression models. The introduction of covariance and mean structure models reduces the number of parameters to be estimated in fitting the mixture and enables one to investigate a variety of substantive hypotheses concerning the differences between the components in the mixture. Within the general model, individual parameters can be subjected to equality, nonlinear and simple bounds constraints. Confidence intervals are based on the inverse of the Hessian and on the likelihood profile. Several illustrations are given and results of a simulation study concerning the confidence intervals are reported.     

对从HSK题库中计算机自动生成试卷稳定性的试验检验

由计算机从题库中自动生成的试卷能否保持难度的相对稳定？根据IRT进行的等值误差范围有多大？为了回答这些问题,本文以共同组等值作为标准,对基于IRT之上的共同题等值误差进行了试验检验。试验中,采取一定措施保证了考生的动机水平。结果显示,IRT等值的校正方向都是正确的。在4个分测验中有3个分测验的的等值校正效果较理想,1个分测验的等值校正效果不够理想。计算机自动生成的试卷与原有人工命制的试卷在得分方面比较一致,分数相关达到0.931,获得证书的情况也是比较一致的。     

System and flexibility in law

Usually, rhetoric is supposed to provide a model of law which describes legal interactions as volitive, arbitrary, and void of any system. However, the Mainz School, founded by Theodor Viehweg, proves the contrary: without referring to any metaphysics, such as consensus or auditoire universel, it seeks to discover the systematic character and the more or less flexible structures of legal rhetoric.     

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.     

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。     

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.     

试论王龙溪的易学哲学

王畿易学认为易之体用不二,易为心易,太极为心之极,反对以易为书、泥于言象;继承和发展了王阳明的良知易说,视<周易>为提高人的道德修养境界的典籍,在修养方法上力倡先天之学,而以自然为宗.王畿易学是宋明时期陆王一路下来心学派易学思想最根本和最集中的体现,对传统易学起到一种解构的作用,是陆王心学在其本质上的必然结果.     

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.     

师范生职业认同感的效能—价值双维核心模型的构建

以师范生职业认同感研究的"职业能力"和"职业价值"两大取向为基础,根据其单维评估的不足,将职业效能感和职业价值感指标联合,提出师范生职业认同感的效能—价值双维核心模型,并考察该模型在3所部属师范大学的1237名免费师范生中是否存在及其效用。研究表明:(1)模型能有效将免费师范生分组,其中低效能—低价值占31.69%、低效能—高价值占6.63%、高效能—低价值占40.01%、高效能—高价值仅占21.67%,克服了单维评估存在的高估或低估问题;(2)模型在职业认同结果(职业意志感、职业意愿与期望感)、学业满意度、总体生活满意度及未来担忧上的分组效应显著,同时拥有高职业效能感和高职业价值感的免费师范生具有最佳的职业认同感、学业满意度、总体生活满意度和最少的未来担忧。
