项目反应理论观察分数核等值的影响因素

探究带宽选择方法、样本量、题目数量、等值设计、数据模拟方式对项目反应理论观察分数核等值的影响。通过两种数据模拟方式,获得研究数据,并计算局部与全域评价指标。研究发现,在随机组设计中,带宽选择方法表现相似;考生样本量和题目数量影响甚微。在非等组设计中,惩罚法与Silverman经验准则表现优异;增加题目量可降低百分相对误差和随机误差;增加样本量导致百分相对误差变大,随机误差减小。数据模拟方式可影响等值评价。未来应重点关注等值系统评估。     

Acculturation Preference Profiles of Spaniards and Romanian Immigrants: The Role of Prejudice and Public and Private Acculturation Areas

The main goal of this study was to identify acculturation preference profiles using cluster analysis in public and private areas of culture in the host and immigrant populations, and to find out the relationship between these profiles and prejudice levels. Four hundred and ninety-nine Spaniards and 500 Romanians participated in a survey. The sampling of Spaniards was multistage random and the sampling of Romanians was by quota. The results confirm our predictions. Romanians who are less prejudiced against Spaniards prefer assimilation in public areas and integration in private areas. Romanians who are more prejudiced against Spaniards prefer integration in public areas and separation in private areas. Spaniards who are less prejudiced against Romanians prefer integration in both public and private areas. Spaniards who are more prejudiced against Romanians prefer assimilation in both areas.     

Maternal and paternal infant representations: A comparison between parents of term and preterm infants

Objective

Research on parental attachment representations after preterm birth is limited and inconclusive. The present study is the first in which maternal and paternal attachment representations after term, moderately and very preterm birth are compared. In addition, special attention was directed toward disrupted attachment representations.

Method

Mothers and fathers of term infants (≥37 weeks of gestational age, n = 71), moderately preterm infants (≥32–37 weeks of gestational age, n = 62) and very preterm infants (<32 weeks of gestational age, n = 56) participated in the present study. Attachment representations (balanced, disengaged, distorted) about their infants were evaluated with the Working Model of the Child Interview (WMCI). To asses disrupted representations the coding of the WMCI was extended with the disrupted scale (WMCI-D).

Results

The three main classifications of attachment representations were not affected by preterm birth. In addition, there were no gender differences in the rate of balanced representations. In case of non-balanced representations however, maternal representations were more often distorted, whereas fathers showed more often disengaged representations. Results further revealed that maternal disrupted attachment representations were marked by role/boundary confusion or disorientation, whereas paternal disrupted attachment representations were characterized by withdrawal.

Conclusion

Given the gender differences it is essential to tailor interventions according to the attachment representations of the parent, in order to be able to alter their non-balanced and/or disrupted attachment representations.     

Personality and Serum Lipids: Does Lifestyle Account for Their Concurrent and Long‐term Relationships

This study evaluates concurrent and over time associations of personality with measures of three serum lipids associated coronary heart disease morbidity, namely, high‐density lipoprotein cholesterol (HDL‐C), low‐density lipoprotein cholesterol and triglyceride (TRI). Participants were individuals who underwent a health examination at two points of time, T1 (N = 3835) and T2 (N = 2283), about 2.5 years apart. Personality was assessed by the Five‐Factor Model. Health, socioeconomic status and healthy lifestyle behaviours (smoking intensity, physical activity and body weight) were controlled. Regression analyses indicate that the personality factors of neuroticism, extraversion and conscientiousness are each significantly associated with HDL‐C and TRI, both concurrently and over time. However, most of these associations decreased to marginal significance when adjusted for body weight or physical activity as possible mediators. Both concurrent and over time associations of the openness personality trait with HDL‐C and TRI were significant and persisted after adjustment for measures of a healthy lifestyle. This study emphasizes the importance of collecting measures of a healthy lifestyle to better understand how personality might influence serum lipids.

研究生入学考试写作评分的概化理论研究与多面Rasch分析

为了评价和改进硕士研究生入学考试一般能力测试的写作评分,研究者采用概化理论和多面Rasch分析对113位考生的写作样本的评分误差来源、评分信度等进行了探讨.概化理论研究显示,评分者和题目对评分准确性影响不大,以两道写作题的考试设计而言,评分者为2人即可保证评分信度在0.75以上.多面Rasch分析显示,评分者宽严度的估计值及其误差均在可接受的范围内,评分者之间在宽严度上不存在显著差异,且评分者自身在评分时总体上比较稳定.但个别评分者在特定考生特定题目上表现出特殊偏向.概化理论和多面Rasch分析丰富了写作评分研究的量化指标,证实了硕士研究生入学考试一般能力测试的写作评分具有较高的信度.     

Taking religion to heart: the relationship between the Five Factor Model and the New Indices of Religious Orientation among religious students

The relationship between religious orientation and personality has been investigated using several different measures and diverse samples. As part of a larger study, 114 undergraduate students were given the Duke University Religion Index (DUREL) to include only those participants who were considered religious. The final sample of 80 participants were given the NEO Personality Inventory-Revised (NEO PI-R) and the New Indices of Religious Orientation (NIRO). Based on the results of the bivariate correlations, higher levels of intrinsic religious orientation were associated with greater Agreeableness and Conscientiousness. Multivariate analyses further revealed that Agreeableness was the most important personality variable when predicting intrinsic and quest religious orientations, with higher levels of Agreeableness predicting greater intrinsic and lower quest orientations. While lower levels of Neuroticism predicted greater intrinsic orientation, higher levels of Neuroticism predicted greater quest orientations. Higher Conscientiousness predicted greater intrinsic and lower quest orientations. Implications of these findings are discussed.     

高中英语阅读测验中题组模型的选择与应用

本研究通过高中英语阅读测验实测数据,对比分析双参数逻辑斯蒂克模型 (2PL-IRT)和加入不同数量题组的双参数逻辑斯蒂克模型 (2PL-TRT), 探究题组数量对参数估计及模型拟合的影响。结果表明：(1) 2PL-IRT模型对能力介于-1.50到0.50的被试,能力参数估计偏差较大;(2)将题组效应大于0.50的题组作为局部独立题目纳入模型,会导致部分题目区分度参数的低估和大部分题目难度参数的高估;(3)题组效应越大,将其当作局部独立题目纳入模型估计项目参数的偏差越大。     

探索语言水平测验的认知诊断改造和深度分析： 以广州市英语学业考试为例

本研究探索在通用认知诊断模型和相关检验方法的基础上对现有语言水平测验进行诊断改造和分析,分三步进行探索：1）探索对语言水平测试不同的属性和Q矩阵构建途径;2）探索对语言水平测试基于通用模型的建模和效度验证;3）探索对语言水平测试建模后续的深入分析。研究发现：属性分布和总分分布划分的学生水平一致性较高;学生对属性掌握存在性别差异且属性间的难易层级不同;属性模式分布进一步验证了语言属性间关联程度较高以及通用认知诊断模型和相关检验方法对语言测验的适用性。三步式的建模分析可作为对语言水平测验进行认知诊断改造的参考。
