城市居民相对剥夺感的实证研究

问卷调查的结果表明 ,我国城市居民的相对剥夺感相当强烈 ,尽管人们的生活水平大幅度提高了 ,但人们普遍感到自己的相对社会地位和相对经济收入下降了。这种相对剥夺感的强烈程度与被访者的个人生活状况和对社会现实的评价有关。社会利益的调整和价值观念的冲突是相对剥夺感产生的重要原因     

The effect of format and device on the performance and usability of web-based questionnaires

This article explores the comparability of assessment tools under different format conditions. Prior studies have not considered the interaction of format and device on time to complete an assessment and have instead treated each of them separately with conflicting results. This study assesses, by linear regressions using web-based data, the performance of multiple devices under varying formats while controlling for non-device factors such as demographic information. The results of this study add to the growing literature on the equivalence among devices and formats used to collect and interpret performance in a variety of organizational settings.

海员心理测量情境模拟法的可行性分析

分析海员心理测量情境模拟法的可行性,指出情境模拟法长期以来被当成是基于经验的非科学的心理检测方法,然而对于海员的心理素质检测而言,却主要是看海员对特殊情境的应对能力和行为反应方式,这给情境模拟法在海员心理测量中的应用和将其推向科学化提出迫切要求。简要论述传统问卷法的不足,并提出用计算机仿真情境模拟进行海员心理测量的设想。

课程项目中的学习动机、策略与成绩的关系

课程项目是提高学生动手实践能力的重要教学手段。以数字图像处理课为例,探讨课程项目中的学习动机、策略与成绩间的关系。通过改进的学习动机策略量表对上海大学的292名学生进行问卷调查,有效样本为245人,计算学习动机、策略各分量及成绩间的相关系数,并根据课程项目成绩将学生分为高分组与低分组,比较两组间的差异。结果表明：总体学习动机与总体学习策略间存在显著相关性（r=0.49,p<0.001）;学习动机的价值分量及总体学习策略均与课程项目成绩显著相关（p<0.05）,且在项目高低分两组间存在显著差异（p<0.05）;资源管理策略分量在项目高低分组间存在显著差异（p<0.05）。课程项目中学习动机与策略更强的学生能取得更好的项目成绩。     

Bayesian hierarchical models for food frequency assessment

The aim of this study is to assess the biases of a Food Frequency Questionnaire (FFQ) by comparing total energy intake (TEI) with total energy expenditure (TEE) obtained from doubly labelled water(DLW) biomarker after adjusting measurement errors in DLW. We develop several Bayesian hierarchical measurement error models of DLW with different distributional assumptions on TEI to obtain precise bias estimates of TEI. Inference is carried out by using MCMC simulation techniques in a fully Bayesian framework, and model comparisons are done via the mean square predictive error. Our results showed that the joint model with random effects under the Gamma distribution is the best fit model in terms of the MSPE and residual diagnostics, in which bias in TEI is not significant based on the 95% credible interval.

Eyes on the Block: Measuring Urban Physical Disorder Through In-Person Observation

In this paper, we present results from measuring physical disorder in Los Angeles neighborhoods. Disorder measures came from structured observations conducted by trained field interviewers. We examine inter-rater reliability of disorder measures in depth. We assess the effects of observation conditions on the reliability of reporting. Finally, we examine the relationships between disorder, other indicators of neighborhood status, and selected individual outcomes.Our results indicate that there is considerable variation in the level of agreement among independent observations across items, although overall agreement is moderate to high. Durable indicators of disorder provide the most reliable measures of neighborhood conditions. Circumstances of observation have statistically significant effects on the observers’ perceived level of disorder. Physical disorder is significantly related to other indicators of neighborhood status, and to children’s reading and behavior development.This result suggests a need for further research into the effects of neighborhood disorder on children.     

非英语专业大学生的英语听力课堂焦虑研究

焦虑现象是二语习得过程中制约学习效果的重要情感因素之一。为了研究非英语专业大学生英语听力课堂焦虑的现状,文章通过自制量表,以问卷形式测试了合肥工业大学120多名非英语专业大二学生的听力焦虑程度。在对数据进行分析后得出结论：焦虑情绪在英语听力课堂中普遍存在,和听力理解的成效呈明显的负相关;应对策略的适当运用可以在一定程度上缓解这一情绪,从而提高听力。根据调查结果,还探讨了焦虑可能的成因并提出有效的教学手段和应对策略。
