高校思想政治课“微博课堂”网络教学平台建设的思考

微博是近年来网络传媒中发展非常迅速的一项网络应用。随着用户数和使用率的不断增高,微博已经不再仅仅是一种表达意愿、分享心情的工具,它正在向越来越多的领域渗透,发挥着比信息分享、传播与获取更多的作用。在教育领域,微博因其低门槛、易操作的特性,在学生中广受欢迎。通过高校思想政治理论课"微博课堂"的教学实践,探讨高校思想政治课"微博课堂"网络教学平台的理论与实践价值,构建高校思想政治课"微博课堂"网络互动平台,旨在为高校思想政治课开辟思路,提高教育教学质量。     

Improved nonparametric tolerance intervals based on interpolated and extrapolated order statistics

The standard approach to construct nonparametric tolerance intervals is to use the appropriate order statistics, provided a minimum sample size requirement is met. However, it is well-known that this traditional approach is conservative with respect to the nominal level. One way to improve the coverage probabilities is to use interpolation. However, the extension to the case of two-sided tolerance intervals, as well as for the case when the minimum sample size requirement is not met, have not been studied. In this paper, an approach using linear interpolation is proposed for improving coverage probabilities for the two-sided setting. In the case when the minimum sample size requirement is not met, coverage probabilities are shown to improve by using linear extrapolation. A discussion about the effect on coverage probabilities and expected lengths when transforming the data is also presented. The applicability of this approach is demonstrated using three real data sets.     

Anglo‐Australian and non‐Anglophone middle classes: ‘foreign accent’ and social inclusion

Building on the concept of ‘multicultural middle class’, this paper explores social inclusion of professionally educated and employed non‐Anglophone immigrants in Australia. We focus specifically on the perceptions and implications of ‘foreign accent’ in the interaction between two groups of middle‐class Australians: non‐Anglophone immigrants and Anglo‐Australians. ‘Non‐Anglophone immigrants’ are defined as those who arrived in Australia as adults, grew up speaking a language other than English, and therefore usually speak English with a ‘foreign accent’. ‘Anglo‐Australians’ are defined as people born in Australia who grew up in families/households where only English was spoken, therefore speaking with a ‘native Australian’ accent. Through a survey of a targeted sample of respondents, the two groups were asked about their intergroup communication, wider interaction (e.g., intermarriage, friendships and working together) and mutual perceptions. Our findings indicate high levels of agreement between the two groups that Anglophone/non‐Anglophone communication is minimally hindered by comprehension problems due to foreign‐accented speech and cultural differences. Although the positive picture that emerges may reflect specific experiences and attitudes of middle‐class professionals and may not be generalisable, increased contact of the 'multicultural middle class' with its Anglo‐Australian counterpart is likely to be a factor in dissociating foreign accent and negative stereotyping.     

权力作用下中国城市居民的纠纷卷入与应对

社会纠纷始终是社会学关注的重要议题。本文在现有关于社会纠纷的研究基础上,以权力为核心概念,从地位结构观和网络结构观两种理论视角出发,试图提出“权力的强制性及传导机制” 这一理论框架,分析当前中国城市中,个体自身拥有的权力和个体社会网络中的权力对居民的纠纷卷入及其应对行为所产生的影响。CGSS2006的数据结果表明,第一,无论是个体自身的权力还是个体社会网络中的权力,都有助于居民规避社会纠纷;第二,无论是个体自身的权力还是来自其社会网络中的权力,居民占有的权力资源越多,就越可能使用正式渠道来应对纠纷。     

关于汉语词类问题的反思

研究实践表明,汉语词类划分存在词无定类或类无定职以及循环论证的问题。汉语词类问题源于西方语言学,印欧语言的词类是一种有形态制约的句法手段,汉语没有这样的形式手段。汉语词类是一种“赤裸裸”的意义类,由于词的意义与句法功能之间有比较稳定的关联,句法功能可以作为意义同类的验证手段。目前以句法功能为标准划分词类,是为了讲语法方便,这只是一个权宜方案。由于词类是词与句法结构的接口,汉语词类研究应该着力探寻词的意义与句法功能之间的关联,进而转向直接研究词与句法结构的接口问题。     

A Note on the Compatibility of Bivariate Copulas

This article answers to a problem by Kolesárová, Mesiar, and Sempi about the class of all copulas that are compatible with two given bivariate copulas A and B. It is shown that, even if A and B are not completely dependent, the class of all copulas compatible with A and B may consist of a singleton.     

On Complete Convergence for Weighted Sums of NA Random Fields

In this paper, we prove the complete convergence for the weighted sums of negatively associated random variables with multidimensional indices. The main result generalizes Theorem 2.1 in Kuczmaszewska and Lagodowski (2011 Kuczmaszewska, A., Lagodowski, Z.A. (2011). Convergence rates in the SLLN for some classes of dependent random field. J. Math. Anal. Appl. 380:571–584.[Crossref], [Web of Science ®] , [Google Scholar]) to the case of weighted sums.     

Modelling Uncertainty and Overdispersion in Ordinal Data

In this article we introduce a probability distribution generated by a mixture of discrete random variables to capture uncertainty, feeling, and overdispersion, possibly present in ordinal data surveys. The choice of the components of the new model is motivated by a study on the data generating process. Inferential issues concerning the maximum likelihood estimates and the validation steps are presented; then, some empirical analyses are given to support the usefulness of the approach. Discussion on further extensions of the model ends the article.     

The Clustering of Categorical Data: A Comparison of a Model-based and a Distance-based Approach

For clustering multivariate categorical data, a latent class model-based approach (LCC) with local independence is compared with a distance-based approach, namely partitioning around medoids (PAM). A comprehensive simulation study was evaluated by both a model-based as well as a distance-based criterion. LCC was better according to the model-based criterion and PAM was sometimes better according to the distance-based criterion. However, LCC had an overall good and sometimes better distance-based performance as PAM, although this was not the case in a real data set on tribal art items.
