父母教养与学业成就：心理因素的中介作用

近十几年来,研究者们致力于探究父母教养与子女学业成就关系的内在机制。认知、大五人格、动机与自我概念作为学习者的心理特质,在父母教养与学业成就间起着重要的中介作用。父母教养能通过影响这些心理因素间接地影响子女的学业成就。尽管研究者们在该领域已经取得较为丰富的研究成果,仍需要在将来加强综合性研究、应用研究和跨文化比较研究,以深化和拓展对这一领域的探索,同时促进已有研究成果的应用。     

一个带有事务管理的动态偏好逻辑

问题对偏好的变化会有影响。本文在偏好逻辑的背景下考虑事务管理并提出了一个新的带有事务管理的动态偏好逻辑。我们的逻辑表明它能把其他情况均同的偏好（ceteris paribus preference）与普通的偏好联系起来并将其动态化和显性化。并且,通过引入混合逻辑使得我们能在同一层次谈论命题和对象之间的偏好,除提问这个行动之外,我们还在逻辑系统的动态部分考虑了解决、建议和软公开宣告等行动。在对这四种行动的不同影响进行比较后,我们证明了这个动态系统的完全性。

Sample size planning with the cost constraint for testing superiority and equivalence of two independent groups

The allocation of sufficient participants into different experimental groups for various research purposes under given constraints is an important practical problem faced by researchers. We address the problem of sample size determination between two independent groups for unequal and/or unknown variances when both the power and the differential cost are taken into consideration. We apply the well‐known Welch approximate test to derive various sample size allocation ratios by minimizing the total cost or, equivalently, maximizing the statistical power. Two types of hypotheses including superiority/non‐inferiority and equivalence of two means are each considered in the process of sample size planning. A simulation study is carried out and the proposed method is validated in terms of Type I error rate and statistical power. As a result, the simulation study reveals that the proposed sample size formulas are very satisfactory under various variances and sample size allocation ratios. Finally, a flowchart, tables, and figures of several sample size allocations are presented for practical reference.     

New heterogeneous test statistics for the unbalanced fixed‐effect nested design

When the underlying variances are unknown or/and unequal, using the conventional F test is problematic in the two‐factor hierarchical data structure. Prompted by the approximate test statistics (Welch and Alexander–Govern methods), the authors develop four new heterogeneous test statistics to test factor A and factor B nested within A for the unbalanced fixed‐effect two‐stage nested design under variance heterogeneity. The actual significance levels and statistical power of the test statistics were compared in a simulation study. The results show that the proposed procedures maintain better Type I error rate control and have greater statistical power than those obtained by the conventional F test in various conditions. Therefore, the proposed test statistics are recommended in terms of robustness and easy implementation.     

自然主义集合实在论与数学哲学研究范式

In recent 50 years,the debate between mathematical realism and anti-realism has been dominating the mainstream development in the contemporary philosophy of mathematics. Penelope Maddy proposed a naturalistic set theoretic realism in 1990. This project brings the philosophy of mathematics a new research idea,that is,philosophy should attach importance to mathematical practice. This article will critically analyze Maddy's naturalistic set theoretic realism on the basis of research paradigm background belief....     

哈尼族自然宗教的神职人员——莫批

莫批是哈尼族社会生活中的重要角色之一。他们既是自然属性的人,又是人神交界的代言人;他们曾经是哈尼族社会政治领袖人物,又是宗教祭司。莫批作为哈尼人民为人处事的楷模,又是哈尼人人生价值的标榜。本文在分析莫批产生的历史演变基础上,阐述莫批在哈尼族社会中的功能和地位及其在哈尼族地区构建和谐社会和保护生物多样性中具有的重要现实意义。     

一致的先前知识对类别学习影响机制探讨

探讨一致的先前知识对类别学习的影响,包括2个实验。被试是112名大学生,分别探讨不同实验任务和不同项目呈现时间引发的机械特征在类别学习中的重要程度和加工程度不同的情况下先前知识对类别学习的影响。结果表明:(1)在实验任务为项目类别归属判断任务时,机械特征重要程度低,主题特征与机械特征在学习上存在竞争关系;在实验任务为项目类别归属及记忆任务时,机械特征重要程度高,主题特征与机械特征在学习上存在促进关系。(2)在限制步速呈现项目时,机械特征加工程度低,主题特征与机械特征在学习上存在竞争关系;而在自定步速呈现项目时,机械特征加工程度高,主题特征与机械特征在学习上不存在竞争关系。     

“物质无限可分”是全称存在命题

运用分析哲学方法研究物质可分性问题,能够得到这样的结果:"物质无限可分"是全称存在命题;"物质有限可分"是存在非存在命题。而这两个命题都既不可证实又不可证伪。因此,"物质结构是否无限可分"是一个超经验的信仰问题,无法从经验上证明究竟是肯定回答正确,还是否定回答正确,因而这方面的争论没有什么意义。     

显示方式对小学生阅读动态文本的影响

以小学三年级和五年级学生为被试,在机控速度（240字/分）条件下,如何在单行呈现动态文本以提高小学生的阅读绩效。实验采用2（呈现方式：引导式、RSVP）×2（年级：三年级、五年级）×2（窗口：5字、10字）的多因素混合实验设计。结果发现：（1）在呈现方式上,平滑滚动引导式优于RSVP,更受被试偏爱;（2）在两种呈现方式下,五年级的阅读正确率显著高于三年级;（3）与平滑滚动引导式相比,窗口大小对RSVP的影响更大。
