菲利普·罗斯小说《人性的污点》是其"美国三部曲"之一,作品展示了一幅美国当代社会不同阶层的生活图景。目前,学界大多从族裔视角和道德层面对该小说进行研究,然而,从新现实主义视角阐释小说主人公科尔曼·希尔克的悲剧,更加凸显了少数族裔在当代美国社会的真实生活境遇。  相似文献

印度现代印地语女性作家曼奴·彭达莉在其代表作《班迪》中展现了女性主义思考和成熟的女性叙事策略。她通过孩童的新颖视角,挖掘女性的内心世界并将其客观地呈现给大众。印度知识女性在传统男权社会中是处于边缘化的群体,曼奴·彭达莉巧妙地运用策略使"雪恭"这个印度知识女性的符号从社会边缘上升为小说文本的主体。她将自己对女性的关注和深刻的认识蕴藏在表层化的儿童视角中,既关注了离异家庭中儿童的遭遇,又对印度知识女性群体表现出了极大的人文关怀。  相似文献

"侨易学"作为一种具有中国文化特色的新兴理论,对于美国非裔的研究提供了丰富的思想资源。从"侨易学"理论出发,分析侨易主体黑人在美移民生活境况,洞察黑人与美国社会的互动效应,见证黑人在侨动过程中身份建构的嬗变。从而得出,黑人要想在多族裔,多文化的美国社会中重拾自我,并在跨文化氛围内获得族裔生活的范式规律,则:既不能规避主流文化的影响,同时又必须珍视本族裔的中坚思想,保持族裔认同感,最终经历"侨动"与"易变"的洗礼,并完成黑人的少数族裔身份建构。  相似文献

印度妇女一直深受印度种姓制度的影响。虽然英国殖民者的入侵强行打破了印度的自然进程,使大量的农村妇女进入城市,在某种程度上改善了妇女的状况,但深厚的宗教情结使得已经神圣化了的种姓制度依然支配着人们的心灵。在当时印度人心里。种姓制度是一座很难推倒的心狱。近年来,随着社会的进步和时代的发展,很多印度妇女真正走出家庭.进入多种职业领域,经济、政治地位有所改善,而要从根本上提高印度妇女地位,应该从文化上淡化宗教意识,使妇女真正自觉自立自强。  相似文献

<正>从地缘政治的角度来看,东边的日本(连同美日同盟)已经对中国的海洋地缘政治构成了有效制约,西南边的印度又如何呢?实际上,在海洋地缘政治的构架内,无论从哪个角度来看,中国和印度的关系越来越具有特殊的重要性。越来越多的因素阻碍着中国解决与印度的领土纠纷问题中国在西边没有直接的出海口,离中国最近的就是印度洋了。中国通往印度洋必须通过邻国巴基斯坦或者  相似文献

国家利益是各个国家制订外交战略的最终依据,在印度对中国西藏政策上也不例外。考察中华人民共和国成立以来的中印关系史,我们不难发现,以下因素明显占据了印度在考虑对中国西藏政策时的重心:一是历史的继承性,即沿承英国的对藏政策;二是文化的影响性,即从印度传统文化的角度来制订对藏政策;三是安全的防范性,即把中国西藏视为印度的战略缓冲区。不过上述因素在历史的不同时期所起的作用是不同的,因国际、国内形势的变化而有所偏重。  相似文献

Language markedness is a common phenomenon in languages, and is reflected from hearing, vision and sense, i.e. the variation in the three aspects such as phonology, morphology and semantics. This paper focuses on the interpretation of markedness in language use following the three perspectives, i.e. pragmatic interpretation, psychological interpretation and cognitive interpretation, with an aim to define the function of markedness.  相似文献

The discovery of the prolific Ordovician Red River reservoirs in 1995 in southeastern Saskatchewan was the catalyst for extensive exploration activity which resulted in the discovery of more than 15 new Red River pools. The best yields of Red River production to date have been from dolomite reservoirs. Understanding the processes of dolomitization is, therefore, crucial for the prediction of the connectivity, spatial distribution and heterogeneity of dolomite reservoirs.The Red River reservoirs in the Midale area consist of 3~4 thin dolomitized zones, with a total thickness of about 20 m, which occur at the top of the Yeoman Formation. Two types of replacement dolomite were recognized in the Red River reservoir: dolomitized burrow infills and dolomitized host matrix. The spatial distribution of dolomite suggests that burrowing organisms played an important role in facilitating the fluid flow in the backfilled sediments. This resulted in penecontemporaneous dolomitization of burrow infills by normal seawater. The dolomite in the host matrix is interpreted as having occurred at shallow burial by evaporitic seawater during precipitation of Lake Almar anhydrite that immediately overlies the Yeoman Formation. However, the low δ18O values of dolomited burrow infills (-5.9‰~ -7.8‰, PDB) and matrix dolomites (-6.6‰~ -8.1‰, avg. -7.4‰ PDB) compared to the estimated values for the late Ordovician marine dolomite could be attributed to modification and alteration of dolomite at higher temperatures during deeper burial, which could also be responsible for its 87Sr/86Sr ratios (0.7084~0.7088) that are higher than suggested for the late Ordovician seawaters (0.7078~0.7080). The trace amounts of saddle dolomite cement in the Red River carbonates are probably related to "cannibalization" of earlier replacement dolomite during the chemical compaction.  相似文献

Language is a means of verbal communication. People use language to communicate with each other. In the society, no two speakers are exactly alike in the way of speaking. Some differences are due to age, gender, statue and personality. Above all, gender is one of the obvious reasons. The writer of this paper tries to describe the features of women's language from these perspectives: pronunciation, intonation, diction, subjects, grammar and discourse. From the discussion of the features of women's language, more attention should be paid to language use in social context. What's more, the linguistic phenomena in a speaking community can be understood more thoroughly.  相似文献

理论推导与室内实验相结合,建立了低渗透非均质砂岩油藏启动压力梯度确定方法。首先借助油藏流场与电场相似的原理,推导了非均质砂岩油藏启动压力梯度计算公式。其次基于稳定流实验方法,建立了非均质砂岩油藏启动压力梯度测试方法。结果表明:低渗透非均质砂岩油藏的启动压力梯度确定遵循两个等效原则。平面非均质油藏的启动压力梯度等于各级渗透率段的启动压力梯度关于长度的加权平均;纵向非均质油藏的启动压力梯度等于各渗透率层的启动压力梯度关于渗透率与渗流面积乘积的加权平均。研究成果可用于有效指导低渗透非均质砂岩油藏的合理井距确定,促进该类油藏的高效开发。  相似文献

As an American modern novelist who were famous in the literary world, Hemingway was not a person who always followed the trend but a sharp observer. At the same time, he was a tragedy maestro, he paid great attention on existence, fate and end-result. The dramatis personae's tragedy of his works was an extreme limit by all means tragedy on the meaning of fearless challenge that failed. The beauty of tragedy was not produced on the destruction of life, but now this kind of value was in the impact activity. They performed for the reader about the tragedy on challenging for the limit and the death.  相似文献

There are numerous geometric objects stored in the spatial databases. An importance function in a spatial database is that users can browse the geometric objects as a map efficiently. Thus the spatial database should display the geometric objects users concern about swiftly onto the display window. This process includes two operations:retrieve data from database and then draw them onto screen. Accordingly, to improve the efficiency, we should try to reduce time of both retrieving object and displaying them. The former can be achieved with the aid of spatial index such as R-tree, the latter require to simplify the objects. Simplification means that objects are shown with sufficient but not with unnecessary detail which depend on the scale of browse. So the major problem is how to retrieve data at different detail level efficiently. This paper introduces the implementation of a multi-scale index in the spatial database SISP (Spatial Information Shared Platform) which is generalized from R-tree. The difference between the generalization and the R-tree lies on two facets: One is that every node and geometric object in the generalization is assigned with a importance value which denote the importance of them, and every vertex in the objects are assigned with a importance value,too. The importance value can be use to decide which data should be retrieve from disk in a query. The other difference is that geometric objects in the generalization are divided into one or more sub-blocks, and vertexes are total ordered by their importance value. With the help of the generalized R-tree, one can easily retrieve data at different detail levels.Some experiments are performed on real-life data to evaluate the performance of solutions that separately use normal spatial index and multi-scale spatial index. The results show that the solution using multi-scale index in SISP is satisfying.  相似文献

本文叙述了对海南岛及其毗邻大陆边缘白垩纪到第四纪地层岩石进行古地磁研究的全部工作过程。通过分析岩石中剩余磁矢量的磁偏角及磁倾角的变化,提出海南岛白垩纪以来经历的构造演化模式如下:早期伴随顺时针旋转而向南迁移,后期伴随逆时针转动并向北运移。联系该地区及邻区的地质、地球物理资料,对海南岛上述的构造地体运动提出以下认识:北部湾内早期有一拉张作用,主要是该作用使湾内地壳显著伸长减薄,形成北部湾盆地。从而导致了海南岛的早期构造运动,而海南岛后期的构造运动则主要是受南海海底扩张的影响。海南地体运动规律的阐明对于了解北部湾油气盆地的形成演化有重要的理论和实际意义。  相似文献

In the 19th century the society was controlled by men, and women were just appendants of them, they had not any rights and freedom. But Jane was an exception, she showed some characteristics of early feminist. Jane showed her characteristics of feminism in three aspects: rebellion, equality, and independence. These characteristics were helpful to her success, and feminism is the only way out for women of that time.  相似文献
