中国梦想家——关于90后中国人混合价值观转变的新兴观点

作者： Gregory j.dubois 上海外国语大学

学位级别：硕士

对于外文化者而言,中国的内文化是极其复杂且难于理解的。中国是有史以来人类最早的文明发源地之一;然而自19世纪以来,中国也在发生了着深刻的文化变化。因此,当前文化研究对如何准确地描绘当今中国文化现状,描绘中国文化的变化方向,阐释变化产生的原因,仍存在不小的困难。很多学者认为,日益增多的西方文化产品和文化信息输入导致中国的年轻一代正朝着个人主义价值取向转变。但是,此类观点恰好与同样简单化标签化地归纳中国文化为“集体主义”的论断是相互冲突的。因此,基于一系列扎根理论的研究,本文采用了主位研究的方法,聚焦于在中国90后群体中极为盛行的概念“梦想”,分析其背后所蕴藏的文化价值观变化。具体而言,本文旨在探索目前在中国年轻一代流行的“梦想”是否是全然来自于西方的概念;进而探讨中国90后的文化价值观发生了何种变化,而这些文化价值观变化是否可以映射“梦想”这一概念的渗透。研究发现,尽管大多数受访者的梦想的确是是纯粹地源于个人兴趣爱好,但他们对“梦想”地追逐与个人主义价值观的增强之间并没有必然联系。确切地说,通过对中国当代青年对“梦想”的描述进行分析,研究揭示了四个理想结果价值观与三个过程价值观,一共七种价值观;他们部分与中国传统价值观吻合,而部分又与现代价值观或西方价值观契合。其中最引人注意的发现在于,在中国90后眼中,“梦想”是一个纯粹的本土概念。通过大量量化研究,多维度以及价值观研究,本文为了解中国年轻一代的多重价值观提供了丰富而深刻的见解,为学者向世界阐述“新”中国提供了全新的视角。

某些学者.主要是美国学者,根据骨盆的放射线测定数据和解剖学标本调查提供的资料,认为真正的产科骨盆上口平面应为骨盆横径和耻骨联合后径所规定的平面。因此,骨盆入口切接于此平面内,就应在这个平面上来测量骨盆上口的形状、大小及其骨盆倾斜度。在该平面上没有骶骨岬的凸起,致使上口呈现椭圆形,以骨盆上口最大横径作为标准,上口的前、后两孤并不对称,故传统的分娩机转似应修改:分娩时;由于耻骨联合上缘与骶骨岬形成一个峡口(峡口轴斜向后下方),胎头在骨盆上口的上方,取横位,并向后肩倾斜,因而胎头并非垂直于骨盆上口以进入骨盆腔内的。虽然.这些问题的解答不能完成令人满意,大部分解答是假设性的,因传统概念阻碍现实的看法。或在这方面应当形成论证。我们从三方面的论据中重新研究,希能提供一确切答案。某些法国或外国学者用骨盆放射线测定数据,例如LANCHOU教授的解剖实验标本资料。本世纪初,一个女性骨盆的解剖标本制品是从后向前通过无名线作一断面,至耻骨联合上缘为止。保留尚未被切断的一小块骨质,以免遗失,但这并不妨碍看清整个断面的范围,这个断面很清楚地划分出大骨盆和小骨盆(产科骨盆)。至于放射学方面的论据,就更成为要求修正的有力理论根据。难道今后不能离开放射线学数据面阐述骨盆和分娩机制,因过去我们只凭想象而论证。一般说来,放射线骨盆测量是在怀疑骨盆有异常时才采用,不适于正常骨盆的研究。但也有人从100例放射线的骨盆测量资料中,选出正常骨盆30例,以此确定骨盆上口的位置、形状及其在入盆的机转。Ridberg分析分娩过程中的X线摄片,指出在分娩过程中胎儿的姿势和活动并非象课堂上讲授的那样。另外有些学者,在详述放射线学论证后,尽管方法上仍有不合理的地方,但仍然回到传统的说法上来。我们浏览了法国和国外的文献后,看到一些临床病例报告,既合乎实际,又彼此相符;但他们的论述前后不一,说了不算数。

作者： David j.Bottjer Department of Earth Sciences University of Southern California

The defining feature of a mass extinction and its associated recovery is the global amount of extinction that occurred[1]. However, there is finer-scale detail to the story, as seen in the ongoing modern mass extinction(the sixth mass extinction), which exhibits variable effects among marine ecosystems and environments, and hence geographic areas [1].

A strong motivation for studying mass extinctions is understanding how current climatic and biodiversity crises will affect creatures living on land such as ourselves. Perhaps the question is: how bad can it get? In that case, terrestrial Permian-Triassic mass extinctions are an irresistible worst-case scenario [1].

A recent study by Adams and colleagues published in Nature unveiled more than one hundred genes that are involved in micronucleus formation,1 which is a biomarker for genomic instability and associated with aging,cancer,and other disorders.2 As an outstanding achievement,the authors identified DSCC1(DNA Replication And Sister Chromatid Cohesion 1)as a critical gene protecting against early developmental defects,genomic instability,reduced proliferative capacity,cohesinopathy-related phenotypes,and tumor development in vivo.

The global trend towards raising broiler chickens without the use of in-feed antibiotics(IFAs) means that there is an ongoing need to develop alternative treatments capable of delivering the benefits that IFAs previously provided. IFAs supported the productivity performance of chickens and played a key role in maintaining their health. Necrotic enteritis(NE) is an important disease of broilers that affects health,productivity, and welfare, and was previously well controlled by IFAs. However, with the reduction in IFA use, NE is resurgent in some countries. Vaccines and various feed additives, including pre-, pro-, and postbiotics, phytobiotics, fatty acids, and phage therapies have been introduced as alternative methods of NE control. While some of these feed additives have specific activity against the NE pathogen, Clostridium perfringens, most have the more general goal of reinforcing gut health. Extensive reviews of the effects of many of these feed additives on gut health have been published recently. Hence, rather than cover previously well reviewed areas of research this review focuses on the challenges and pitfalls in undertaking experimental assessment of alternative NE treatments and translating laboratory research to real world commercial production settings. The review is based on the author's particular experience,reading, thoughts, and analysis of the available information and inevitably presents a particular understanding that is likely to be at odds with others thinking on these issues. It is put forward to stimulate thinking and discussion on the issues covered.
