论卡瑞·丘吉尔的《九重天》中性别属性的不确定性

英国著名剧作家卡瑞·丘吉尔的《九重天》中性别压迫不但体现在女性被扭曲的个体上,甚至在克莱夫之子爱德华艰难的性别角色寻求中。本文以剧中人物爱德华在两幕剧中孜孜不倦地寻求性别身份为线,探讨剧作家丘吉尔运用人物性别身份的颠倒、错位与拼贴,以及重建母系神话等方式或行为,从而说明人类社会性别属性的不确定性。对此展开研究有助于读者认清当下非异性恋(包括同性恋)话语权的建构,以宽容姿态看待同性恋现象,并以团结友爱的精神为纲,实现社会和谐。     

Quark and Gluon Condensates at Finite Temperatures by the Linear Sigma Model Approach

Based on a linear sigma model, we discuss the mixing between a quark condensate and a gluon condensate. It is shown that the linear sigma model will not be self-consistent if we switch off the mixing coupling between glueball and chiral fields. By introducing a proper mixing coupling, we realize the second-order phase transitions of chiral symmetry restoration and deconfinement. We further show that the critical temperature of chirM symmetry restoration could not be larger than the temperature of deconfinement phase transition in all possible parameter spaces of our model.
