Cognitive diagnosis models (CDMs) have been used as psychometric tools in educational assessments to estimate students’ proficiency profiles. However, most CDMs assume that all students adopt the same strategy when approaching problems in an assessment, which may not be the case in practice. This study develops a generalized multiple-strategy CDM for dichotomous response data. The proposed model provides a unified framework to accommodate various condensation rules (e.g., conjunctive, disjunctive, and additive) and different strategy selection approaches (i.e., probability-matching, over-matching, and maximizing). Model parameters are estimated using the marginal maximum likelihood estimation via expectation-maximization algorithm. Simulation studies showed that the parameters of the proposed model can be adequately recovered and that the proposed model was relatively robust to some types of model misspecifications. A set of real data was analysed as well to illustrate the use of the proposed model in practice. 相似文献

According to recent studies, people on both the political right and left show prejudice toward groups whose beliefs are in conflict with their own. This prediction applies to both cultural and economic dimensions of political beliefs. In three studies (N = 499) we demonstrate that people on both the cultural and economic right and left show negative attitudes toward groups on the other side of the given spectrum and that underlying this effect is the perception of value violation. In two out of three studies, we manipulated the extremity of target worldviews to further explore the causal chain between political beliefs, the perception of value violation, and prejudice. Our results showed a high degree of symmetry between the political left and right in their attitudes toward groups with dissimilar beliefs. However, although people on both sides of the political spectrum show prejudice toward each other, people on the cultural and economic right seem to be more sensitive to value violations than people on the left. 相似文献

在政治伦理论域中,多元文化主义和女性主义已成为自由主义正义论在当前的强劲对手.以社会批判理论著称的南希·弗雷泽就是以这样一种双重身份介入了这场论辩,提出了有关"后社会主义时代"的正义构想.弗雷泽提出"地位模式的承认"将承认的合法性框限在仅和社会平等地位相关的范围内,用以强调对承认正义的诉求绝不可遮蔽对再分配正义的反省与批判,并据此构建了一种以"平等参与"为支点的"双焦点的正义概念"和""视角上的二元论方法"来表达对当前社会不正义的关注. 相似文献

Initial psychometric properties of the experiences questionnaire: validation of a self-report measure of decentering 总被引:1,自引:1,他引:0

Decentering is defined as the ability to observe one's thoughts and feelings as temporary, objective events in the mind, as opposed to reflections of the self that are necessarily true. The Experiences Questionnaire (EQ) was designed to measure both decentering and rumination but has not been empirically validated. The current study investigated the factor structure of the EQ in both undergraduate and clinical populations. A single, unifactorial decentering construct emerged using 2 undergraduate samples. The convergent and discriminant validity of this decentering factor was demonstrated in negative relationships with measures of depression symptoms, depressive rumination, experiential avoidance, and emotion regulation. Finally, the factor structure of the EQ was replicated in a clinical sample of individuals in remission from depression, and the decentering factor evidenced a negative relationship to concurrent levels of depression symptoms. Findings from this series of studies offer initial support for the EQ as a measure of decentering. 相似文献

Pandora is a tool for supporting the learning of first ordernatural deduction. It includes a help window, an interactivecontext sensitive tutorial known as the "e-tutor" and facilitiesto save, reload and export to LATEX. Every attempt to applya natural deduction rule is met with either success or a helpfulerror message, providing the student with instant feedback.Detailed electronic logs of student usage are recorded for evaluationpurposes. This paper describes the basic functionality, thee-tutor, our experiences of using the tool in teaching and ourfuture plans. 相似文献

SAS and SPSS macros to calculate standardized Cronbach’s alpha using the upper bound of the phi coefficient for dichotomous items 总被引:1,自引:0,他引:1
Cronbach’s α is widely used in social science research to estimate the internal consistency of reliability of a measurement
scale. However, when items are not strictly parallel, the Cronbach’s α coefficient provides a lower-bound estimate of true
reliability, and this estimate may be further biased downward when items are dichotomous. The estimation of standardized Cronbach’s
α for a scale with dichotomous items can be improved by using the upper bound of coefficient ϕ. SAS and SPSS macros have been
developed in this article to obtain standardized Cronbach’s α via this method. The simulation analysis showed that Cronbach’s
α from upper-bound ϕ might be appropriate for estimating the real reliability when standardized Cronbach’s α is problematic. 相似文献

Satisfaction and psychological well-being as antecedents of organisational commitment. The role of organisational commitment in public administration and its repercussions on the institution are examined in this study. It reports part of a larger research project that studies job satisfaction, life satisfaction, and psychological well-being as antecedents of organisational commitment. Data were collected from 697 public-sector employees, using questionnaires. Results showed that job satisfaction, life satisfaction, and psychological well-being were strong predictors of organisational commitment. Higher levels of job satisfaction, life satisfaction, and psychological well-being were associated with more favourable perceptions of organisational commitment. Furthermore, this study highlights the impact of dynamic work on the employee's commitment. 相似文献

Parasuraman, Zeithaml, and Berry introduced SERVQUAL in 1998 as a scale to measure service quality. Since then, researchers have proposed several variations. This study examines the development of the tool. Marketing researchers have first challenged the conceptualization of a perceptions-expectations gap and have concluded that the performance-based measures are adequate to capture consumers' perception of service quality. Some researchers have argued that the five dimensions of the SERVQUAL scale only focus on the process of service delivery and have extended the SERVQUAL scale into six dimensions by including the service outcome dimension. Others have proposed that service quality is a multilevel construct and should be measured accordingly. From a sample of 467 undergraduate students data on service quality toward up-scale restaurants were collected. Using the structural equation approach, two measurement models of service quality were compared, the extended SERVQUAL model and the restructured multilevel SERVQUAL model. Analysis suggested that the latter model fits the data better than the extended one. 相似文献

网络使用线索对不同动机使用者上网欲望的诱发作用 总被引:2,自引:0,他引:2
以67名信息获取性动机者和54名人际情感性动机者为被试,以基于实景照片的网络信息获取线索、网络情感满足线索和负性情绪线索为刺激材料,采用线索暴露范式探讨了网络使用线索对网络使用者上网欲望的相对影响。实验结果表明,网络信息获取线索仅对信息获取性动机者的上网欲望具有显著的诱发作用,而情感满足线索和负性情绪线索仅对人际情感性动机者的上网欲望具有显著的诱发作用。该研究为解释人际情感性动机者的病理性互联网使用行为特征提供了实验证据。 相似文献
