足球德比文化研究

运用文献资料法和专家访谈法,对足球德比文化的现象与内涵、形成因素及其特征、形成的理论解释进行了研究。指出,德比现象与内涵都随社会变化得到延展,现象上从最初的地理对抗向文化领域甚至更大范围扩展,内涵上对德比的概念界定从客观条件向主观条件延伸。认为,群体间的冲突、同侪、偏见对德比的形成和延续有显著作用,显示出德比的形成因素具有竞争性、相似性、差异性三方面的特征。“争议密度”和“竞争对手威胁论”是用来解释德比形成原因的两大理论,经过比较分析,认为竞争对手威胁论可以更为清晰地解释德比的形成与延续的内涵,克服了以往研究的局限性。对于我国足球而言,探究足球德比文化具有重要现实意义,通过借鉴西方的成熟经验培育具有中国特色的足球文化,亦有助于我国足球“三步走”战略目标的实现。     

How does education have an impact on ethnocentrism? A structural equation analysis of cognitive,occupational status and network mechanisms

Previous studies have distinguished cognitive, occupational status and network mechanisms in the relation between education and ethnocentrism. Hypotheses on these mediating mechanisms are derived from socialization theory, realistic group threat and contact theory. In the current study we use structural equation modeling to investigate the explanatory power of these three mechanisms simultaneously. The analysis is based on a representative population survey from the Netherlands (NELLS 2009, n = 1910). The results show that more than half of the initial association between education and ethnocentrism can be attributed to cognitive ability and occupational status mechanisms. The remaining part of the overall association, however, still has to be modeled as a direct relationship between education and ethnocentrism. This direct association can be attributed either to social desirability or to a direct liberalizing effect of education on social and political attitudes. Our analysis tentatively suggests that the rise of average education levels in Western societies might lead to less ethnocentric attitudes via the cognitive sophistication mechanism.     

Authoritarianism, perceived threat and exclusionism on the eve of the Disengagement: Evidence from Gaza

Major political events such as terrorist attacks and forced relocation of citizens may have an immediate effect on attitudes towards ethnic minorities associated with these events. The psychological process that leads to political exclusionism of minority groups was examined using a field study among Israeli settlers in Gaza days prior to the Disengagement Plan adopted by the Israeli government on June 6, 2004 and enacted in August 2005. Lending credence to integrated threat theory and to theory on authoritarianism, our analyses show that the positive effect of religiosity on political exclusionism results from the two-staged mediation of authoritarianism and perceived threat. We conclude that religiosity fosters authoritarianism, which in turn tends to move people towards exclusionism both directly and through the mediation of perceived threat.     

Examining the effects of news coverage linking undocumented immigrants with criminality: Policy and punitive implications

Although research suggests that there is no meaningful real-world connection between crime rates and undocumented immigrants, media coverage of this group almost exclusively portrays them as criminals. The present two-study investigation experimentally tests the effects of exposure to crime news depicting undocumented immigrant suspects on White viewers’ social judgments. To this end, assumptions from social identity theory were applied to research and theorizing on mediated intergroup threat and compound penalties for immigrant criminality. Results from Study 1 and Study 2 indicate that when White viewers are exposed to threatening crime news featuring undocumented immigrants, out-group bias emerges in the form of harsher sentencing. In Study 1, when exposed to highly threatening coverage, attitudes toward immigration and in-group identification partially mediated and moderated this relationship, respectively.     

CAS Scientists Reveal the Genetic Basis of Drug Resistance in Mycobacterium tuberculosis

<正>Tuberculosis(TB)is a chronic respiratory disease caused by Mycobacterium tuberculosis and is a serious threat to human health.Every year there are 1.3 million new cases of TB worldwide,100,000 of which are multidrug resistant.The TB burden in China is the second highest in the world.The widespread occurrence of multidrug(MDR)and extensively drug-resistant(XDR)tuberculosis is making the treatment of TB more and more problematic.Research on the mechanisms underlying drug resistance,one of the most important,diffi cult and competitive areas of TB research worldwide,has been carried out in the labs of Professors BI Lijun and ZHANG Xian’en at the Institute of Biophysics,CAS.On September 1st,2013,Nature Genetics     

《文选》所载应璩《百一诗》探微

《文选》收录应璩《百一诗》一首,结合应璩其人所处时代及其生平才具,对于应璩写作此首《百一诗》之创作动机及心理作了一番探索。认为应璩写作此首《百一诗》,目的主要不在规箴曹爽,也不是为了表现自己的修为,而是在司马氏集团与曹爽争夺权力的乱局背景下,出于朱建平死亡预言的恐惧,面对司马氏集团的侵诬行为,所作出的惊弓之言而已。

我国民族传统体育文化发展的SWOT分析

借助SWOT分析方法从优势、劣势、机遇和挑战四个维度对我国民族传统体育文化发展进行深入分析研究,结果认为:优势在于其依附于中国传统文化,具体体现在具有顽强的生命力和凝聚力;具有鲜明的主体性和整合性;具有独特的东方哲学思想和持久的激励性.劣势在于附加了一种比较片面的、趋向于自我封闭的文化倾向,具体表现在相对自我封闭,数字化传播过程中居于劣势,数字鸿沟明显;缺乏科学合理的评价标准;国人对中国文化的认识和了解存在断层,文化自觉意识仍亟待加强三个方面.现代信息技术的发展为传统体育文化注入了新的活力;文化产业的发展使民族传统体育文化成为东西方文化交流的纽带是其发展的机遇所在.以西方体育文化为主体的域外文化冲击;西方文化霸权主义对中国民族传统体育文化母体的威胁是其面临的主要挑战.
