不知是大牌设计师们突发奇想,还是近年来流行的自然风已平淡得让人生厌。总之,2006年的女人们开始拒绝平凡、抵制朴素,怎样的女人才能称得上是合格的拜金女呢?《W》的专栏作家苏珊娜的答案是:"必须要深刻了解限量版物质所带来的精神意蕴,因为,那是时尚的格调,是挑剔到尖锐并且很私人的癖好,这种私人癖好能及时地展现她们与众不同、卓尔不群的个性……"

在西方历史上,姐妹情谊经历了从家庭范围内的血亲关系走向公共领域中的女性友谊,继而形成女性共同体的漫长历程。美国华裔女作家谭恩美在《喜福会》中对姐妹情谊的书写,在继承西方女性文学传统中“百纳被”叙事和审美的基础上,融合了以“麻将会”为象征符号的、和合共生的中国传统文化思想和理念,消解了姐妹情谊在性别、阶级、族裔等问题上的二元对立,调和了女性共同体内部同质化与个性化的矛盾,为姐妹情谊在多元文化冲突与融合背景下的继承和发展提供了华裔女性的智慧和策略。

Molecular Plant 2010年第1期3卷 91-100页

Sinapoylmalate is the major sinapate ester found in leaves of Arabidopsis thaliana, where it plays an important role in UV-B protection. Metabolic profiling of rosette leaves from 96 Arabidopsis accessions revealed that the Pna-10 accession accumulates sinapoylglucose instead of sinapoylmalate. This unique leaf sinapate ester profile is similar to that of the previously characterized sinapoylglucose accumulator1 （sngl） mutants. SNG1 encodes sinapoylglucose：malate sinapoyltransferase （SMT）, a serine carboxypeptidase-like （SCPL） enzyme that catalyzes the conversion of sinapoylglucose to sinapoylmalate. In the reference Columbia genome, the SNG1 gene is located in a cluster of five SCPL genes on Chro- mosome II. PCR and sequencing analysis of the same genomic region in the Pna-10 accession revealed a 13-kb deletion that eliminates the SNG1 gene （At2g22990） and the gene encoding sinapoylglucose：anthocyanin sinapoyltransferase （SAT）（At2g23000）. In addition to its sinapoylmalate-deficient phenotype, and consistent with the loss of SAT, Pna-10 is unable to accumulate sinapoylated anthocyanins. Interestingly, the Pna-17 accession, collected from the same location as Pna-10, has no such deletion. Further analysis of 135 lines collected from the same location as Pna-10 and Pna-17 revealed that four more lines contain the deletion found in Pna-10 accession, suggesting that either the deletion found in Pna-10 is a recent event that has not yet been eliminated through selection or that sinapoylmalate is dispensable for the growth of Arabidopsis under field conditions.

“心”是中国文化的核心概念和最基本特性,作为中国文化三大主干之一的道文化概莫能外。道文化主要是关于“心”的心理学思想,主要从个体生命构成的视界探究“心”的地位和作用,建构起以“心”为核心的生命哲学和心理学思想体系,可称之为“道文化心理学”。道文化心理学是研究道文化在其形成和发展过程中逐渐形成的以“道”为核心的独具道文化特色的结构化的意义系统或心理系统,是解决人的存在矛盾性的独特的基本方式。它具有如下基本性质和特征:道法自然的基本态度,天乐的情感方式,体认式心理感悟模式,以道观之的认知方式,阴阳相即的辩证思想。

近年来,三晋民歌一直是学界研究的热点,但晋南地区民歌的艺术特色尚未得到应有的关注和研究。本文尝试以晋南乡宁县新民歌为研究对象,分析其思想内容与美学特征。从思想内容来看,乡宁县新民歌包括:迎接港澳回归,表达对祖国繁荣的赞美之情;怀恋故乡热土,表达对家乡人民的思念之意;赞美无私奉献,表达对高尚品德的传承之歌;弘扬爱国精神,表达对全国人民的团结之爱等。从美学视角考察,乡宁县新民歌具有以“颂”为美、以“雅”为美、以“器”为美、以“和”为美等美学特征。通过上述解读,不仅能够加深人们对晋南乡宁县新民歌的认知与理解,而且可以进一步传承与发扬中华优秀传统艺术文化。

错误妊娠之诉的损害赔偿责任探讨

在比较法上,错误妊娠诉讼目前已基本得到支持,但其损害赔偿范围仍存争议。错误妊娠诉讼表现为侵权之诉或违约之诉,两者的诉讼主体有所不同,但救济结果殊途同归。尽管医务人员的过失行为侵害了原告夫妇生育权,但新生命降生为家庭带来之喜悦作为精神得益可扣减其父母生育权受到侵害的精神损害。在意外出生的子女抚养费问题上,基于亲子人伦、生命尊严及父母义务等考量因素,应缓和适用完全赔偿原则,故子女抚养费不具有可赔偿性。错误妊娠诉讼中医疗机构最终须赔偿的仅仅是因手术失败侵害孕妇健康权造成的损害。
