皖西白鹅内分泌器官的形态学研究

本试验研究了皖西白鹅内分泌器官的形态学特征。试验应用20只成年皖西白鹅(公母各10只),进行新鲜标本和10％福尔马林溶液固定标本的观察,同时比较公母鹅间内分泌器官的差异。结果表明成年皖西白鹅的体重为:公鹅5.05±0.72千克,母鹅4.88±0.68千克,公鹅的内分泌器官量值较母鹅略大。     

《白鹿原》：回归传统的平庸

本文通过对于黄土坡塬上的精神哲学－“白鹿精魂”－及其理想人格范型的解读,从一个侧面论述了回归传统是《白鹿原》的文化本性。文章指出,《白鹿原》并没有提供富有现代人文价值的文化观念,并没有最大可能地开掘人物灵魂的深度,它的成功在于以貌似丰厚沉静的鲁钝品性回应了九十年代文化民族主义的主潮。回归传统既成就了它,也埋葬了它。从这一角度言,《白鹿原》无疑是一部资质平庸的作品。     

“狼”与“狗”之间的转化:进化还是退化?

杰克·伦敦是美国杰出的批判现实主义作家,被誉为"美国无产阶级文学之父"。但他不是一位真正的无产阶级作家,因为他在接受马克思主义的同时,也接受了达尔文的进化论、斯宾塞的社会进化论和尼采的"超人"哲学。世界观的矛盾和思想的撞击充分体现在他的两部动物小说《野性的呼唤》和《白牙》中。     

Taking time,breaking codes: moments in white teacher candidates’ exploration of racism and teacher identity

Abstract

In three narrative vignettes, this paper challenges scholars and practitioners of teacher education to consider ways that our courses do and do not engage white teacher candidates to take on racially conscious orientations. The work addressed in this paper has implications for our understandings of how preservice teachers can learn about racial identity in ways that benefit individual teachers and support their work in schools and communities. These findings buttress previous work in ‘second wave’ white teacher identity research and can translate directly into teacher education course and program design. Simultaneously, this research speaks to the broader literature in teacher education, offering evidence to support the value of extended periods of time for new teachers to build authentic relationships and conduct critical study of self and society in a climate where teacher preparation programs face pressure to reduce credits to degree and intensify their focus on preparing students for externally mandated assessments.     

从《最蓝的眼睛》中的两例会话分析看白人文化对黑人心灵的戕害

《最蓝的眼睛》是美国著名黑人女作家托妮·莫里森（1993年度诺贝尔文学奖获得者）的处女作。小说通过一个黑人小女孩佩科拉的悲惨遭遇,控诉了占霸权统治地位的白人文化对黑人心灵上的戕害。本文选了小说中的两例会话,运用格赖斯的合作原则与会话含义理论进行会话含义分析,旨在探究人物会话行为背后所蕴合的深刻社会原因,同时也为该小说的文本批评提供一个新的视角。     

概念整合视阈下的文学经典重构——以巴塞尔姆的《白雪公主后传》为例

文章基于概念整合理论的基本概念整合网络模型运作机制,以唐纳德·巴塞尔姆的《白雪公主后传》为例,对该作品中展现出来的反童话主题进行认知分析,以期证实概念整合理论对此类经典重构的文学作品的解释力,同时为读者理解和品析美国其他后现代文学作品提供新借鉴.     

论《白雪歌送武判官归京》的感情脉络——兼评《“风掣红旗冻不翻”新解》

岑参的<白雪歌送武判官归京>是以白雪为背景的送别之作,将送别之情寓于咏雪之中,以融情入景的笔法,暗示送别之情,形成隐伏于篇中的感情脉络.但<"风掣红旗冻不翻"新解>一文,却对"风掣红旗冻不翻"作了曲解,认为"风掣"二字,正是"红旗冻不翻"的根本原因","北风将红旗全部吹开并拉直","红旗在空中一动不动","丝毫不翻卷".这样的"新解",颅不合<白雪歌送武判官归京>一诗的实际,既穿凿于写景的理解,又丢弃了"风掣红旗冻不翻"的表情作用.     

Production of recombinant enveloped structural proteins from the Chinese WSSV isolate

The white spot syndrome virus (WSSV) is one of the deadly pathogens of penaeid shrimps and other crustaceans. The WSSV virion consists of an enveloped rod-shaped nucleocapsid enclosing a large circular double stranded DNA genome of 305 Kb with 181 open reading frames. The two major structural genes, VP19 and VP28 were amplified from the genomic DNA of Chinese isolate of WSSV and cloned in pUCm-T vector and sub cloned in pET-30a (+) vector. The expressions of genes inE. coli (BL21) were confirmed by SDS-PAGE analysis. The clones were sequenced, submitted to the gene bank and the Xiang Shan strain of WSSV were compared with the previous reported sequence of WSSV of various regions which revealed that VP19 and VP28 gene sequences had certain differences from the sequences of similar genes of the isolate already reported. The recombinant proteins expressed, purified and characterized.     

文学与叙事之维的历史存在——论海登·怀特的后现代历史叙事学

海登·怀特（Hayden White）的后现代历史叙事学理论拆解了文学、历史与哲学之间的藩篱,从而将史学批评转向了对叙事活动本身的观察。在他看来,历史只能以叙事的方式存在,而叙事则是一种有目的的组织意义的过程。这便使得有关历史的研究具有一种文学叙事学研究的意味。这一理论创见,对于史学研究以及一切有关历史的文本化叙事活动的研究都有着深刻的启示意义。
