地方新建本科院校体育、艺术类学生英语自主学习能力培养研究

随着地方新建本科院校招生规模逐年扩大,体育、艺术类学生的招生量也在不断地增加。作为大学英语教学的对象,体育、艺术类学生是一个特殊的学生群体,他们普遍存在着英语基础差、学习自主性程度和水平不高、学习策略水平不高等特点。文章旨在通过行动研究的方法为体育、艺术类学生的大学英语教学提供一个课内外相结合的自主学习教学模式,以期提高学生的英语学习效率。     

杠杆化和公允价值计量模式对商业银行业绩的影响

2007年4月开始的美国次贷危机到2007年底还没有对美国的商业银行造成太大的打击。但2008年9月雷曼兄弟的破产撼动了商业银行生存的根基。本文分析表明,商业银行的业务越来越多地涉足到资本市场,而去杠杆化和公允价值计量模式使商业银行的业绩在很大程度上受资本市场波动的影响。     

Is abusive supervision an absolute devil? Literature review and research agenda

Abusive supervision has received increasing attention in the field. However, few studies have qualitatively reviewed its latest developments. The current paper reviews 48 studies on abusive supervision using content analysis. We identify six emerging trends of abusive supervision, including inconsistency of abusive behaviors, comparison between perceived and objective behaviors, reciprocity, team-level climate, coworker effects, and comparisons between theoretical perspectives. Based on a review of those six trends and some emerging findings, we identify and validate the possible positive effects of abusive supervision from an integrated analysis. We also determine the moderating role that Asian culture plays in differentiating the negative and positive effects of abusive supervision. Specifically, we identify the differences between Asian and Western cultures, and then explore the moral mechanisms (i.e., violation of moral standards, conflict of moral principles) through which abusive supervision may exert positive effects in the Asian cultural context. Finally, we clarify our theoretical implications and provide suggestions for future research.     

Calibration Weighting Methods for Complex Surveys

This paper presents a careful investigation of the three popular calibration weighting methods: (i) generalised regression; (ii) generalised exponential tilting and (iii) generalised pseudo empirical likelihood, with a major focus on computational aspects of the methods and some empirical evidences on calibrated weights. We also propose a simple weight trimming method for range‐restricted calibration. The finite sample behaviour of the weights obtained by the three calibration weighting methods and the effectiveness of the proposed weight trimming method are examined through limited simulation studies.     

PSC指标在VFM评价中的应用研究

Testing for serial correlation and random effects in a two-way error component regression model

In this paper, we test the existence of serial correlation and random effects in a two-way error component regression model with panel data. Under moment conditions alone, we suggest several easily implemented tests based on the parameter estimators for artificial autoregressions modeled by the differences in residuals. Under the null hypotheses, the tests for serial correlation are two-sided and asymptotically chi-square distributed, whereas those for random effects are one-sided, and are asymptotically standard normally distributed variables. Moreover, these methods can also be used similarly to construct tests for both serial correlation and individual effects jointly, whether or not time effects are present. The proposed tests are able to detect local alternatives that are distinct from the null at the parametric rate. Monte Carlo simulations and real data applications are carried out for purposes of illustration.
