Controlling item exposure and test overlap on the fly in computerized adaptive testing

This paper proposes an on‐line version of the Sympson and Hetter procedure with test overlap control (SHT) that can provide item exposure control at both the item and test levels on the fly without iterative simulations. The on‐line procedure is similar to the SHT procedure in that exposure parameters are used for simultaneous control of item exposure rates and test overlap rate. The exposure parameters for the on‐line procedure, however, are updated sequentially on the fly, rather than through iterative simulations conducted prior to operational computerized adaptive tests (CATs). Unlike the SHT procedure, the on‐line version can control item exposure rate and test overlap rate without time‐consuming iterative simulations even when item pools or examinee populations have been changed. Moreover, the on‐line procedure was found to perform better than the SHT procedure in controlling item exposure and test overlap for examinees who take tests earlier. Compared with two other on‐line alternatives, this proposed on‐line method provided the best all‐around test security control. Thus, it would be an efficient procedure for controlling item exposure and test overlap in CATs.     

Dispositional resistance to change: measurement equivalence and the link to personal values across 17 nations

The concept of dispositional resistance to change has been introduced in a series of exploratory and confirmatory analyses through which the validity of the Resistance to Change (RTC) Scale has been established (S. Oreg, 2003). However, the vast majority of participants with whom the scale was validated were from the United States. The purpose of the present work was to examine the meaningfulness of the construct and the validity of the scale across nations. Measurement equivalence analyses of data from 17 countries, representing 13 languages and 4 continents, confirmed the cross-national validity of the scale. Equivalent patterns of relationships between personal values and RTC across samples extend the nomological net of the construct and provide further evidence that dispositional resistance to change holds equivalent meanings across nations.     

青少年冒险行为及其与人格、依恋的关系

该文采用问卷法对671名初、高中生及大学生进行青少年冒险行为、人格、同伴依恋调查。结果发现,性别、年龄、独生子女与否对青少年冒险行为均有不同程度的影响作用;人格五因素既对青少年冒险行为有直接预测作用,又以同伴依恋的疏远维度为中介间接影响青少年冒险行为。     

大学生公民教育新路径探析

当代中国的马克思主义是大学生公民教育的思想基础;培育中国特色社会主义共同理想的社会主义建设者是大学生公民教育的发展目标;传承与发扬民族精神与时代精神是大学生公民教育的重要使命;坚持弘扬社会主义荣辱观是大学生公民教育的实践方向.大学生公民教育要取得实效,一要不断探索新的实践路径,二要大力营造全社会共同关心高校公民教育的氛围.     

EZ does it! Extensions of the EZ-diffusion model

In this rejoinder, we address two of Ratcliff’s main concerns with respect to the EZ-diffusion model (Ratcliff, 2008). First, we introduce “robust-EZ,” a mixture model approach to achieve robustness against the presence of response contaminants that might otherwise distort parameter estimates. Second, we discuss an extension of the EZ model that allows the estimation of starting point as an additional parameter. Together with recently developed, user-friendly software programs for fitting the full diffusion model (Vandekerckhove & Tuerlinckx, 2007; Voss & Voss, 2007), the development of the EZ model and its extensions is part of a larger effort to make diffusion model analyses accessible to a broader audience, an effort that is long overdue.     

评价性条件反射效应：无条件刺激的呈现时长、效价强度与关联意识的作用

以真实商标图案为条件刺激, 情绪图片为无条件刺激, 探索无条件刺激呈现时长、效价强度与关联意识对评价性条件反射效应的影响。实验通过结合四图再认测验与基于项目分析, 对关联意识的作用进行了详细探讨。结果表明, 评价性条件反射效应只发生在无条件刺激长呈现水平与无条件刺激强效价水平; 评价性条件反射效应的产生需要基于被试的关联意识。关联意识在呈现时长(效价强度)与评价性条件反射效应间的中介作用不显著。结果不支持评价性条件反射的内隐错误归因机制及联想-命题评价模型的相关论断, 部分支持命题性解释模型。     

Academic Integrity from China to the United States: The Acculturation Process for Chinese Graduate Students in the United States

The ethics-related beliefs of Chinese international graduate students are heavily influenced by their academic cultural background, and given the nature of that culture, they often face challenges when adapting to the U.S. academic environment. This qualitative study examines Chinese graduate students’ perceptions of the differences between Chinese and American academic integrity practices and the effects of those differences on their ethical practices and adaptations in a graduate program in the United States. Data were collected via semistructured interviews in a public university in the United States. Findings suggest that perceptions of academic integrity in Chinese universities are influenced by Confucian philosophy, collectivist assumptions, and a resultant convenience mind-set. These cultural premises clash with academic expectations in the United States. Participants describe how they, and their Chinese peers, navigate U.S. integrity standards and provide recommendations for ways that U.S. schools can help them better adjust. We expand on those and provide recommendations for university personnel.     

儿童心理虐待与忽视和自杀意念的关系：有调节的中介模型

采用问卷法对988名初中生进行调查,探究儿童心理虐待与忽视和自杀意念的关系,应对方式的中介作用以及友谊质量的调节作用。结果表明：（1）儿童心理虐待与忽视正向预测自杀意念;（2）应对方式是儿童心理虐待与忽视和自杀意念之间的中介变量;（3）儿童心理虐待与忽视对自杀意念的直接效应受到友谊质量的调节,直接效应对于友谊质量低的青少年更显著;（4）儿童心理虐待与忽视通过应对方式对自杀意念的间接效应的后半段受到友谊质量的调节,友谊质量高的青少年的自杀意念水平相对更低。因此,儿童心理虐待与忽视和自杀意念之间是有调节的中介关系,儿童心理虐待与忽视通过应对方式影响自杀意念,友谊质量在直接路径和间接路径中起调节作用。
