《红与黑》的心理学阐释

按照弗洛伊德的理论,把人的精神生活分为意识、潜意识两个主要部分,那么<红与黑>中"红与黑"的含义从心理学角度也可以这样看:"红"代表意识;"黑"代表潜意识;<红与黑>中处处体现着人物内心的矛盾和紧张,整部作品充斥着"力",是红与黑的较量,是意识与潜意识的斗争.     

Making the most of “external” group members in blended and online environments

Although the importance of boundary spanning in blended and online learning is widely acknowledged, most educational research has ignored whether and how students learn from others outside their assigned group. One potential approach for understanding cross-boundary knowledge sharing is Social Network Analysis (SNA). In this article, we apply four network metrics to unpack how students developed intra- and inter-group learning links, using two exemplary blended case studies in Spain and the UK. Our results indicate that SNA based upon questionnaires can provide researchers some useful indicators for a more fine-grained analysis how students develop these inter- and intra-group learning links, and which cross-boundary links are particularly important for learning performance. The mixed findings between the two case-studies suggest the relevance of pre-existing conditions and learning design. SNA metrics can provide useful information for qualitative follow-up methods, and future interventions using learning analytics approaches.

Snippets of physics

One of the celebrated results in black hole physics is that black holes have a temperature and they emit a thermal spectrum of radiation. Though a rigorous derivation of this result requires quantum field theory, a flavour of the essential ideas can be provided at an elementary level as indicated here. T Padmanabhan works at IUCAA, Pune and is interested in all areas of theoretical physics, especially those which have something to do with gravity. This is based on an article originally published by the author in Physics Education, Vol. 24, p.67, 2007.     

“女性主义”行动策略下的黑人女性主体性建构——解读艾丽丝·沃克的三部长篇小说

黑人女性不仅在经济上,而且还在政治上、文化上都处于权力的边缘地位,沦为失去自主性的非人存在。黑人女作家艾丽斯·沃克在创作实践中依托黑人女性的特殊经验,坚持＂女性主义＂的行动策略,将处于边缘地位的黑人女性置于文本的中心主体位置。其作品深刻揭示了黑人女性在白人主导的社会中所遭受的多重压迫,探索了黑人女性在男性霸权社会中建构自我的艰难历程,彰显了黑人女性鲜明的女性自我主体意识和对平等的两性关系的追求。
