从作者性别批评视角看简·爱和吕蓓卡的人物形象差异

简·爱与《名利场》中的女主角吕蓓卡是英国维多利亚时期文学中两个具有同样独立反叛意识但被作者赋予不同命运结局的女人。从作者的性别视角去解读这两个传统女性形象的本质差异,能看出男女作者对女性反抗压迫行为的不同理解和价值判断,并能更好地发掘出被别的批评视角忽略或误读的文本内涵。     

中西方对青少年异性交往的态度及教育效果比较

对青少年异性交往的态度，中国自古以来比较保守、消极，西方比较开放、积极，我们应该把二者的优点结合起来．把青少年的异性交往引入健康的轨道。     

不容忽视的审计细节

就注册会计师在执业过程中必须关注的一些细节，如对管理当局声明书的依赖问题，会计资料中的非常数字，采用询证法对应收帐款的查询，实地观察公司运营情况，符合性测试以及对作为审计证据的公司函，复印件等问题进行了探讨。     

如何避免英文中的歧视性语言

歧视性语言是指一个社会中的强势群体把自己视为社会的规范和中心,在语言交际过程中,毫无必要地或不恰当地指出对方的性别、年龄、种族或民族等,将对方划入某一弱势群体,表示出对其的轻视、冒犯或侮辱.笔者在本文中就如何避免在英文交际的过程中使用歧视性语言作了论述.     

论铁凝对女性模仿性生存的女性叙事

铁凝一直自我定位于“第三性”写作,可是读罢她的大多数小说之后,却发现了她不同的小说中存在着一个共同的女性生存模式——模仿。这种模仿与生存处境的弱势有关,模仿中的焦虑与性别弱势有关。铁凝的“第三性”声明是作家刻意的性别遮蔽。     

Determination of diel periodicity of sex pheromone release in three species of Lepidoptera by ‘closed-loop-stripping’

Summary By means of closed-loop-stripping and subsequent GC analyses the diel periodicity of release of (Z)-11-hexadecenyl acetate, (E)-8-dodecenyl acetate, and (Z)-9-tetradecenyl acetate, the main constituents of the respective sex pheromone blends ofMamestra brassicae, Cryptophlebia leucotreta andSpodoptera sunia females, was determined.Pheromones, 64. For the 63rd contribution we have taken from: Szöcs, G., Toth, M., Bestmann, H. J., Vostrowsky, O., Heath, R. R., and Tumlinson, J. H., Z. Naturforsch.42c (1987) 165; Pheromones, 62: Bestmann et al.¹³.     

Tamoxifen ‘sex reverses’ alligator embryos at male producing temperature,but is an antiestrogen in female hatchlings

Summary Tamoxifen is an anticancer drug widely used in the treatment of estrogen-dependent breast cancer. In hatchling alligators it acts as a pure antiestrogen in that it completely blocks the effect of estradiol-induced oviductal hypertrophy and completely blocks the estradiol-induced hepatic vitellogenin secretion. Paradoxically, when injected into alligator eggs incubated at 33°C, a temperature which would normally result in 100% male hatchlings, tamoxifen sex reverses the embryos into apparently normal female hatchlings.     

Sex pheromone of the pine sawflyDiprion pini (Hymenoptera: Diprionidae): Chemical identification,synthesis and biological activity

The main component of the sex pheromone secretion of femaleDiprion pini L. (Hymenoptera: Diprionidae) from insects collected both in Finland and in France has been identified as athreo-3,7-dimethyl-2-tridecanol (8 ng per female) stereoisomer by GC-MS and synthesis. The secretion also contains lower and higher homologues in small amounts (1–4% of the main component). Combined gas chromatographic-electroantennographic detection showed activity in both natural and esterified extracts (acetates and propionates); the esters of the main component gave the largest responses. The acetates and propionates of the eight stereoisomers of 3,7-dimethyl-2-tridecanol were synthesized from enantiomerically highly enriched (>99% ee) building blocks. The stereochemistry of the main component was established to be (2S,3R,7R)-3,7-dimethyl-2-tridecanol by GC analysis of the natural material. It was purified by liquid chromatography prior to the GC analysis of both its pentafluorobenzoates and its isopropylcarbamates on a non-chiral polar column (ECD) and a chiral column (NPD), respectively. Field tests demonstrated that both the acetate and propionate of the main component (100 g of each applied on cotton roll dispensers) were active in attracting males, with or without the presence of several of the minor compounds. Experiments with smaller amounts of the acetate and the propionate (1 g in France and 50 g in Finland) demonstrated that the propionate was more active than the acetate, and that it also caught more males than a blend of the two compounds.
