中、美大学网站规模的对比研究*     

段宇锋  刘伟 《现代图书情报技术》2005,21(11):72-76

网站规模是决定网站信息资源丰裕度和用户信息检索效率的重要因素，网站的字节数、总文件数、页面文件数和总链接数是目前用于衡量网站规模最重要的指标。本研究以美国101所著名商学院和医学院的网站，以及国内7所知名财经院校的网站为研究对象，通过对中、美网站以及美国商学院与医学院网站的比较分析，不仅明确了中、美网站在规模上的差异，更重要的是为大学网站建设和评价提出了具有重要价值的参考数据。  相似文献

宝贡敏 《资源科学》1994,16(4):55-61

我国乡镇工业企业的发展与环境、资源的协调问题已经成为我国发展与环境、资源关系方面的大问题。实际工农相对分离，组建乡村工业区，是提高乡镇工业企业素质、效益、强化乡镇工业企业优化组合、规模经营的有效途径；是保护环境，实现资源有效利用的基础工作之一；是提高农业劳动生产率，实现农业规模经营的基础工作之一。  相似文献   

大学新生英语课堂焦虑状况调查     

傅慧英  王皓璇 《培训与研究》2007,24(6):112-114

运用定量研究的方法,采用Horwitz等的“外语课堂焦虑量表”,对浙江科技学院119名大学英语新生的英语课堂焦虑状况作了统计分析。结果表明,大学英语新生的英语课堂焦虑度是比较高的。女生焦虑度比男生高,但是没有显著性差异;外语焦虑和外语学习效果之间呈现显著的负相关关系;焦虑程度越高,对于外语学习的负面影响越大。据此提出了一些减轻大学生外语焦虑的方法和建议。  相似文献   

Differences of math anxiety groups based on two measurements,MASS and EEG     

Sang S. Choi-Koh  Byeong G. Ryoo 《教育心理学》2019,39(5):659-677

This article investigated how mathematic anxiety (MA) of Korean middle school students could be reduced by comparing analytically their cognitive neuroscience and questionnaire results. We developed a three-hour Complex Treatment Program (CTP) on quadratic functions for the study. In the summer of 2016, we collected data of the pre and post MA questionnaires by Mathematics Anxiety Scale for Students (MASS), the percent of correct answers (PCA) and reaction time (RT) by E-prime program, and also brain-imaging data of the event related potentials (ERP) by Electroencephalograph (EEG) using computer-based functional F-G model. The result indicated the CTP to be effective with the group with higher math anxiety and the group with higher achievement respectively. The MASS result was verified with the better performance of PCA on type G, which was measured by E-prime program. Some interesting patterns were revealed on brain-imaging data by EEG, indicating more brain activities with the MA groups.  相似文献

Empathy towards people of different race and ethnicity: Further empirical evidence for the Scale of Ethnocultural Empathy     

Paolo Albiero  Giada Matricardi 《Int J Intercult Relat》2013

The present study examined the generalizability of the factor pattern, structural parameters, and latent structure of a multidimensional hierarchical model of ethnocultural empathy in males and females. The Scale of Ethnocultural Empathy (SEE) (Wang et al., 2003) was administered to a sample of 610 Italian undergraduates to examine the generalizability and reliability of its factor structure across gender, the psychometric properties and the validity of the scale. Two models were tested through multi-group confirmatory factor analysis (MGCFA): a confirmatory factor-analytic model that hypothesized a multidimensional model of ethnocultural empathy; and a structural equation model that proposed a multidimensional, hierarchical structure with global ethnocultural empathy as a superordinate construct that explained the covariances among the subdomains of the SEE. Both models satisfied multiple criteria for goodness-of-fit with the data. Full metric invariance of factor loadings and factor covariances, and partial invariance of error variances across gender for the four-factors model were supported. Scale reliability was also satisfactory, showing good internal consistency. As regard scale validity, evidence was found for a positive moderate association with a measure of general empathy and a negative high association with a measure of prejudice. Implications are discussed.  相似文献   

New media environments’ comparative effects upon intercultural sensitivity: A five-dimensional analysis     

Amy Jo Coffey  Rasha Kamhawi  Paul Fishwick  Julie Henderson 《Int J Intercult Relat》2013

An experimental 2 (channel) × 2 (gender) × 3 (time) mixed factorial design (N = 159) was applied to test and compare how individual dimensions of intercultural sensitivity might be affected by two channels: a virtual environment (i.e., Second Life^®) versus a Web environment. Using a modified version of Chen and Starosta's Intercultural Sensitivity Scale (ISS), the study sought to identify which of the five ISS dimensions played the most influential role in intercultural sensitivity outcomes: interaction enjoyment, interaction engagement, interaction confidence, interaction attentiveness, or respect for cultural differences. Results showed that one's willingness and effort toward understanding an intercultural interaction – interaction attentiveness – played the greatest and most statistically significant role in intercultural sensitivity outcomes, and that this effect was greatest within the virtual environment channel. Gender effects were also found, in which men experienced greater enjoyment but women expressed more attentiveness.  相似文献
