图书馆服务质量的本土化模型：高阶因子结构与测量

在回顾图书馆服务质量测评当前研究状况的基础上,建立了五维度(因子)的本土化图书馆服务质量模型,并证实存在高阶因子主宰五维度的表现。经过严谨的信度与效度检验,该模型不仅有效揭示了图书馆服务质量测量的高阶因子结构关系,而且可以确定测量指标对各因子的影响程度。据此,将图书馆服务质量指数化,为其改进提供依据。

A study of the validity of four types of student ratings of college teaching assessed on a criterion of student achievement gains

The purpose of the study was to investigate relationships between student ratings of college teaching using four types of student rating instruments and pre- vs. post-student achievement gains in 36 sections of an undergraduate analytic geometry and calculus course. Student rating instruments used varied according to type of items (high vs. low inference) and focus (students rating their own perceived growth vs. rating the instructor). Data were collected on 799 students (66% freshmen; 16% sophomore; and 15% juniors) at the University of Florida, and relationships were analyzed using the Pearson product-moment correlation technique. Significant relationships were not found between student ratings and student achievement.     

Penn State Worry Questionnaire: structure and psychometric properties of the Chinese version

The Penn State Worry Questionnaire (PSWQ) is a measure of worry phenomena and has been demonstrated valid in cross-cultural populations. The present study examined the factor structure and psychometric properties of the Chinese version of PSWQ (Ch-PSWQ) in a Chinese college sample (n=1243). Exploratory factor analysis of the Ch-PSWQ revealed a two-factor solution (engagement of worry and absence of worry). Confirmatory factor analysis and model comparison supported that the model of one factor with method effect provided the best fit to the data. The Ch-PSWQ and its factors evidenced good internal consistency and both convergent and discriminate validity. The present study supports the opinion that the second factor of PSWQ not only contains the component of evaluating pathological worry, but also might represent other traits.

谈语言测试的信度

信度在语言测试中非常重要，对于广大语言教师来说，重要的是从一开始就认识到不同因素对信度的影响，因为很多教师倾向于认为测试是绝对可靠的测量工具，却认识不到语言测试只能是一种间接测试，即使是最好的测试在充当测量语言能力的工具时，也有几分不准确。本文简要介绍检验测试信度的方法及提高信度要注意的主要事项。     

New Ways to Evaluate Goodness of Fit: A Note on Using Equivalence Testing to Assess Structural Equation Models

Structural equation models are typically evaluated on the basis of goodness-of-fit indexes. Despite their popularity, agreeing what value these indexes should attain to confidently decide between the acceptance and rejection of a model has been greatly debated. A recently proposed approach by means of equivalence testing has been recommended as a superior way to evaluate the goodness of fit of models. The approach has also been proposed as providing a necessary vehicle that can be used to advance the inferential nature of structural equation modeling as a confirmatory tool. The purpose of this article is to introduce readers to key ideas in equivalence testing and illustrate its use for conducting model–data fit assessments. Two confirmatory factor analysis models in which a priori specified latent variable models with known structure and tested against data are used as examples. It is advocated that whenever the goodness of fit of a model is to be assessed researchers should always examine the resulting values obtained via the equivalence testing approach.     

On Equivalence of Public Sign Translation from the Perspective of the Relevance Theory

At present,with the development of the city culture and globalization,bilingual signs are more widely used in the society.Among the public sign translations,there are many successful examples.But,at the same time,many problems such as mistranslation and poor translation widely exist in the process of promotion of city culture.The relevance theory interprets translation from the original author’s and translator’s cognitive surroundings,thus bringing a new approach for translation,especially for applied text translation.Based on the previous study,the author analyzes the equivalent effect of sign translation from the perspective of the relevance theory and summarizes some principles and strategies for public sign translation,in hope of helping the promotion of the city image and culture.
