实践社区核心成员大五人格特征及其与沟通技能的关系

文章采用修订的大五人格问卷和自编的沟通技能问卷,对宁夏8家企事业单位中15家实践社区的核心成员进行了调查,结果表明:大五人格问卷和沟通技能问卷信度和效度良好;实践社区核心成员一般拥有敏感的、外向的、温和的、开拓性、高利他性、灵活性等人格特质;核心成员的沟通技能在年龄、职位、文化程度、单位性质等变量上均有不同程度的显著性差异;大五人格特质与沟通技能之间存在密切的关系,五个因素中的社交性、开放性和利他性对沟通技能水平具有较大的影响。     

The end of “information”: Computers,democracy, and the university

This paper describes some of the challenges which the growing pervasiveness of computers and electronic communications technology present to liberal democracies. We argue that these technologies, by their influence on the mechanisms of publicity and privacy, make possible the abuse of an under-developed popular epistemology. The confused response of the courts to cases of information crime suggests that the university is a better forum in which to meet and master these challenges.Freedom is not a simple experience. And as technology becomes more sophisticated, living in freedom—which means living with constant, changing choice—will only become more complex.

灰色马尔科夫模型在高校招生中的应用研究

本研究深入剖析了灰色马尔科夫模型在高校招生中的应用,由于高校生源变动的随机性、波动性以及复杂性,给招生预测工作带来了很多瓶颈。为了更准确地预测招生人数,我们将试图把灰色动态预测与马尔科夫预测模型融为一体,对高校招生人数进行预测。选取河南师范大学部分新生历年录取入学情况为研究对象,采用数据收集法、实验分析法、灰色马尔科夫模型等技术发掘数据中隐藏的规律和模式,从而为高校招生工作提供科学的依据。     

Examining Intermediate Omitted Levels in Hierarchical Designs via Latent Variable Modeling

This article outlines an interval estimation procedure that can be used in a 3-level setting to evaluate the proportion of outcome variance attributable to the second level of clustering. The method is useful for examining the necessity of including a possibly omitted intermediate level of nesting in analyses of data from a multilevel study, and represents an informative addendum to current statistical tests of second-level variance. The approach is developed within the framework of latent variable modeling and can be used as an aid in the process of choosing between 2-level and 3-level models in a hierarchical design. The discussed procedure is illustrated with an empirical example.     

Making sense of learner and learning Big Data: reviewing five years of Data Wrangling at the Open University UK

Most distance learning institutions collect vast amounts of learning data. Making sense of this ‘Big Data’ can be a challenge, in particular when data are stored at different data warehouses and require advanced statistical skills to interpret complex patterns of data. As a leading institute on learning analytics, the Open University UK instigated in 2012 a Data Wrangling initiative. This provided every Faculty with a dedicated academic with expertise data analysis and whose task is to provide strategic, pedagogical and sense-making advice to staff and senior management. Given substantial changes within the OU (e.g. new Faculty structure, real-time dashboards, two large-scale adoptions of predictive analytics approaches, increased reliance on analytics), this embedded case study provides an in-depth review of lessons learned of five years of data wrangling. We will elaborate on the design of the new structure, its strengths and potential weaknesses, and affordances to be adopted by other institutions.
