从城市崇拜看阎连科的小说创作

阎连科出生在贫困的乡村,由于童年和少年时期的缺失性体验而产生一种向往城市的心理。这种心理在他的小说中体现为贫瘠土地上的青年农民拼命逃离土地、渴望进入城市的迫切心情。他的小说可以让人感受到主人公在逃离土地之路上挣扎的痛苦心声,同时也可体味到作者希冀精神上回归土地的殷切心情。     

Conceptualizing anxiety among social work students: implications for social work education

Student anxiety is frequently discussed within social work education. Due to its potentially devastating impacts, social work educators need to have a full understanding of anxiety in this context, in order to determine the best way to support students. Research on student anxiety from a broad body of literature provides implications for social work classrooms and field education. Key underlying concepts from previous social work and related research on student anxiety inform a conceptual model to help educators develop a more complex understanding of student anxiety. Implications for further research and important next steps in the development of support strategies for social work students are identified.     

人类学视角中的荣昌陶艺——关于荣昌陶艺的田野调查

荣昌陶器技艺是中国传统陶器技艺的重要组织部分，因其历史悠久、工艺精湛而久负盛名，与江苏宜兴陶、云南建水陶、广西钦州陶并称为中国四大名陶，荣昌又与广东佛山、江苏宜兴一起被誉为中国“三大陶都”。在千百年的传承和发展过程中，荣昌陶器为巴蜀地区人民的生产和生活曾做出过重要贡献。在非物质文化遗产保护热兴起的今天，重新梳理荣昌陶器技艺产生和发展的场境，发掘潜藏在陶器技艺背后的经济和文化动因，能够使我们在文化生态和生产条件发生巨大变化的今天更好地保护、传承和发展荣昌陶艺。

美学研究之当下论域与理论前景

近年来,我国的美学研究蓬勃发展,美学基本原理探讨成效显著,中外美学史梳理有条不紊,部门美学研究异彩纷呈,流派美学研究乐此不疲。其主要特征有五:一是参与者众,成果五花八门;二是师承关系明显,排异性强;三是教材各异,令人无所适从;四是思辨者多,实验取证者少,归纳总结者多,创新者少;五是学位论文俨然成为新见主产地。研究方法主要有哲学思辨法、心理还原法以及语义分析、经验主义、社会学、历史学、系统论等。不足之处即为缺乏理论创新,鲜有大师级人物出现,故此未来之研究应以创新为第一要务,力求把深奥难懂的美学理论阐发得通俗易懂。     

语义场理论对科技术语翻译的启示从——“水资源管理”一词的英汉互译谈起

科技术语在不同语言之间的翻译是一个复杂的语义匹配过程，如何在考虑相关术语使用现状的基础上将新产生的科技术语准确翻译为其它语言是科技工作者和术语研究者关注的重要问题。以语义场理论为分析框架，通过分析以"水资源管理"及其相关术语为代表的英汉互译，结果发现：不同科技术语在同一语义场所涵盖的语义范围将会随着相关研究深化带来的术语界定细化而发生相应的动态变化；新兴科技术语的翻译要充分考虑其所在语义场其它相关科技术语的翻译先例和使用现状所带来的影响，在翻译准确性和解读便利性之间做出适当的平衡。这是造成"水资源管理"及相关术语英汉互译处理极为复杂的重要原因之一，需要科技翻译者在工作实践中多加注意。     

The older the bolder: Does relative age among peers influence children’s preference for competition?

Having been relatively old at school tends to have a long lasting positive effect on professional achievement, in particular in competitive environments (sports, politics). We investigate the roots of this pattern and study whether the relative age position of children at school plays a role in shaping their preference for competition. We run a controlled experiment in high schools across two states in Australia. Our participants are students who are the very oldest or very youngest in their classroom. We elicit their preference for competition using the Niederle and Vesterlund (2007) task and find evidence of an effect of relative age. This effect is concentrated on male students. We find no differences in self-confidence, and risk attitudes between relatively old and young students. These results suggest that the observed pattern may come from pure preference for competition.
