语言多元化的历史演变——基于欧盟官方资料的语料分析

欧盟对语言多元化的理解和构架大致经历了三个阶段：第一阶段（1997--2004年）的文件资料中经常提到语言及语言学习,但还没有明确提出语言多元化这一概念;第二阶段（2004--2007年）公共文件资料中已经明确提出语言多元化,然而却是在教育和文化政策资料中出现,没有将其单列出来;第三阶段（2007--2010年）,欧盟专门出台了语言多元化相关政策或报告,从而基本形成了完备的语言多元化政策格局。欧盟语言多元化对我国少数民族语言保护及外语教育有一定的借鉴意义。

The role of British newspapers in framing the public perception and experience of European radio 1930 to 1939

This article analyses how British newspapers in the 1930s created a particular frame or view of radio as an international medium. This frame was created around the idea of a duality, of radio being defined by both national and foreign broadcasts. By analysing coverage provided by the main national newspapers at this time, in relation to their specific radio coverage, such as programme listing and highlights, this paper delineates the form the frame took, what was included and was absent. Such a frame provides an understanding of how the newspapers viewed and valued radio in a period when international broadcasts were seen as an important part of what radio could offer.     

新欧洲政策与英国“三环”外交的形成

均势和孤立主义是英国欧洲政策的一贯立场,但二战的后果使这一传统政策在战后初期发生了转变。英国不但企图拉住欧洲,缔造“世界第三力量”,而且第一次在和平时期主动与欧洲国家结盟。这是英国欧洲外交在观念和实践上的真正变化。这种变化所引起的政策调整促成了“三环”外交的形成。     

Estimating the causal effect of R&D subsidies in a pan-European program

We investigate the effect of Europe's largest multilateral subsidy program for R&D-performing small and medium-sized enterprises. The program applied a specific budget allocation rule, referred to as Virtual Common Pot (VCP), which is designed to avoid cross-subsidization between participating countries. This rule creates exogenous variation in funding status and allows us to identify the causal effect of public R&D grants on firm growth. In addition, we compare the program's effect under the VCP rule with the standard situation of a Real Common Pot (RCP), in which program authorities allocate a single budget according to uniform project evaluation criteria. Our estimates suggest that R&D grants had no average effect on job creation and sales growth, but treatment effects were heterogeneous and positive for high-quality projects. Under an RCP the program would have created 53% more jobs and 48% higher sales.     

The Governance of University Knowledge Transfer: A Critical Review of the Literature

Universities have long been involved in knowledge transfer activities. Yet the last 30 years have seen major changes in the governance of university–industry interactions. Knowledge transfer has become a strategic issue: as a source of funding for university research and (rightly or wrongly) as a policy tool for economic development. Universities vary enormously in the extent to which they promote and succeed in commercializing academic research. The identification of clear-cut models of governance for university–industry interactions and knowledge transfer processes is not straightforward. The purpose of this article is to critically discuss university knowledge transfer models and review the recent developments in the literature on research collaborations, intellectual property rights and spin-offs, those forms of knowledge transfer that are more formalized and have been institutionalized in recent years. The article also addresses the role played by university knowledge transfer organizations in promoting commercialization of research results.

Learning (abroad) mobility in the European Union: A comparison of youth in and out of higher education

In the European Union (EU) context, learning abroad mobility (LAM) also includes non-formal learning activities. Young people can participate in LAM whether they are in tertiary education or not. Nevertheless, studies focusing on the participation of out-of-higher-education (Out-HE) youth in LAM are often scarce. The current study aims to explore the role of several sociodemographic factors in participation in LAM among Out-HE youth, based on the analysis of a large-scale survey conducted across EU member countries. Findings show that Out-HE youth is less likely to participate in LAM than the youth in higher education as expected. However, some socioeconomic factors, such as gender and age, play different roles among Out-HE youth and the youth in higher education in old (EU15) and new member countries (NMS) of the EU.     

对2005世界青年足球锦标赛中国队防守技战术的研究

通过观察2005年世青赛的比赛,以中国青年队为主要研究对象,将比赛中出现的防守行为分为个人防守技战术和集体防守技战术.结果表明:防守中的技战术行为是围绕整体防守队形展开的,表现出很强的整体性特征.断球成为最主要的个人防守形式.围抢是在防守队形的保护层次形成后,在局部区域内,数名防守队员相互协调,围堵控球队员,并将球抢断下来的一种集体性的防守行为.在前、中、后场各区域内,防守行为表现出不同的战术目的.通过防守行为的整体性和主动性加强防守效果,是中青队在防守中的主导思想.
