An exploratory study of the relationship between the use of the Learning Commons and students' perceived learning outcomes

This study proposes and empirically tests a model explicating the impact of the Learning Commons on university students' learning behaviors and skills development. Adapting the information literacy instruction model that is based on expectation disconfirmation theory, a series of hypotheses were developed, and data were collected through an online survey at a Hong Kong university. Responses from 388 students were subjected to a partial least squares structural equation modeling analysis. The results suggest that expectation disconfirmation theory can be applied in the domain of the Learning Commons, and that the degree to which students' expectations are confirmed affects their degree of perceived quality of and satisfaction with the Learning Commons. Perceived quality in turn influences satisfaction. Both perceived quality and satisfaction lead to psychological outcomes that produce behavioral changes and possible benefits, including time savings, effort reduction, better grades, advanced problem-solving skills, and improved learning outcomes.     

Inhibitory activities of microalgal extracts against Epstein-Barr virus DNA release from lymphoblastoid cells

This study aimed to assess the inhibitory activities of methanol extracts from the microalgae Ankistrodesmus convolutus, Synechococcus elongatus, and Spirulina platensis against Epstein-Barr virus (EBV) in three Burkitt's lymphoma (BL) cell lines, namely Akata, B95-8, and P3HR-1. The antiviral activity was assessed by quantifying the cell-free EBV DNA using real-time polymerase chain reaction (PCR) technique. The methanol extracts from Ankistrodesmus convolutus and Synechococcus elongatus displayed low cytotoxicity and potent effect in reducing cell-free EBV DNA (EC(50)<0.01 μg/ml) with a high therapeutic index (>28000). After fractionation by column chromatography, the fraction from Synechococcus elongatus (SEF1) reduced the cell-free EBV DNA most effectively (EC(50)=2.9 μg/ml, therapeutic index>69). Upon further fractionation by high performance liquid chromatography (HPLC), the sub-fraction SEF1'a was most active in reducing the cell-free EBV DNA (EC(50)=1.38 μg/ml, therapeutic index>14.5). This study suggests that microalgae could be a potential source of antiviral compounds that can be used against EBV.     

基于利益相关者理论的企业并购与反收购决策分析

对于利益相关者理论的提出、概念界定和类型划分,相关文献已经有了比较系统的概括。这里从企业并购的角度对利益相关者理论再做一点简单的分析.通过本文的分析我们可以发现,企业的利益相关者提出并购策略都有各自的利益动机,而反收购主要但并不局限于应对恶意并购,收购与反收购策略是相关者利益的博弈制衡结果.
