3G时代手机媒介传播的构型及意义

随着现代生活信息化节奏的加快与新媒介的日新月畀,个体与媒介展现为充满张力、动态发展的关系。手机媒介传播经历了接打电话、短信交往到达3G网络时代,不仅激发了沟通与生活方式的改变,更促进了生活理念和价值观念的更迭。3G网络时代的手机交往从主体认知和人际交往方式两方面介入了人际传播,从手机出版、广播、影视、网络生活等方面极大地丰富了大众传播。3G网络实现了手机媒介从人际传播到大众传播的转型,手机媒介文化也变身为大众传媒亚文化的典型代表。     

关联理论在语篇教学的应用

英语的语篇教学侧重培养学生对语篇的分析理解能力和逻辑思维能力。该文从关联理论的视角,论述了语篇学习中如何通过语境寻找最佳关联,推断话语含义,从而领会作品的深层意义。文章从四个方面展开探究：通过确定词义之间的关系寻找关联;借助认知语境寻找关联;通过话语的间接性寻找关联;从低调陈述寻找关联。     

Au/SrTiO3（001）界面电子结构的第一性原理研究

采用在密度泛函理论框架下的第一性原理方法,系统地分析了4种可能Au/SrTiO3（001）界面模型的界面能、原子间距、电子结构及其化学键特征.研究表明：Au/SrTiO3（001）界面的稳定性与其界面原子构型密切相关;Au与排列在以TiO2原子层截止SrTiO3（001）表面的氧原子上的界面构型最为稳定.     

基于湖南省域视角的“3+5”城市群发展研究

"3+5"城市群综合实力在湖南省域范围内处于绝对优势,肩负着启动湖南发展的重任。然而,"3+5"城市群在建设和发展的过程中也出现了诸如中心城市竞争力不足、区域发展不平衡、城乡差距较大等问题,因此,唯有对症下药,以"两型社会"建设为突破口,以新型工业化、新型城市化为推动力,提升竞争力、改善产业结构、统筹区域发展、统筹城乡发展,才能使"3+5"城市群真正成为撬动湖南崛起的杠杆。     

Lukasiewicz蕴涵算子的导出算子及其n值逻辑系统Ln

讨论了剩余类蕴涵算子之一Lukasiewicz蕴涵算子的导出算子的三值系统L3和n值逻辑系统Ln（n〉3）,首先给出了L3的真值表,它是C2真值表的扩充,它也保持MP规则和正则性,接下来讨论了b中的重言式（tautology）与IPC（inmitionistic propositional calculus）公理之间的关系以及L3的准重言式与C2的重吉式之间的关系。最后考虑了Ln中的予代数及不同逻辑系统Ln中重言式的比较。

How does early childhood care and education affect cognitive development? An international review of the effects of early interventions for children from different social backgrounds

A number of authors have investigated the impact of early childhood education and care programs on the development of children. Often they have focused on the effects on children from socio-economically disadvantaged families. To assess the effects of various preschool programs on cognitive development, recent key studies were reviewed. In addition, the extent to which these programs could establish equal educational opportunities for children from different social backgrounds was evaluated. Program start, intensity, and duration were considered. The findings indicate that the vast majority of recent early education and care programs had considerable positive short-term effects and somewhat smaller long-term effects on cognitive development and that in relative terms children from socio-economically disadvantaged families made as much or slightly more progress than their more advantaged peers. Despite this, early childhood education and care cannot compensate completely for developmental deficits due to unfavorable learning conditions in disadvantaged milieus. Implications for research and policy are discussed.     

Faculty employment and R&D expenditures at Research universities

This study uses panel data to examine the relationship between faculty employment and external R&D expenditures at Research and Doctoral institutions over a 15-year period of time. On average, a 1% increase in the number of full-time faculty is associated with about 0.2% increase in total R&D expenditure. Further, a one percentage point increase in the share of full-time faculty members that are not on tenure-track lines is associated with a decrease in total external R&D expenditure by about 0.6%, suggesting that full-time faculty that are tenured or on tenure-tracks are the main category of faculty that generate external R&D funding. Further, our results suggest that an increasing usage of part-time faculty, holding constant the institution's full-time faculty size, boosts an institution's external R&D expenditures. On average, a one percentage point increase in the share of part-time faculty members is associated with a 0.44% increase in the total external R&D expenditures. Increases in graduate student enrollments are associated with increases in external R&D expenditures. Finally, an institution's external R&D expenditures are significantly influenced by both the amount of its own institutionally financed research expenditures and the level of federal funding for research.
