A culture of whiteness: How integration failed in cities,suburbs, and small towns

As America's neighborhoods have become more racially diverse in the last half century, are these shared spaces fulfilling the “promise of integration”? In this study, I review the literature on desegregation as it occurs in urban, suburban, and rural places, illuminating how a culture of whiteness works in each of these types of places to reproduce racial domination. The literature on multiethnic urban areas demonstrates how a culture of whiteness reframes gentrification as ‘revitalization’ and nostalgia, which result in social control and cultural displacement of non-white residents. In suburban places, I draw out the ways a culture of whiteness is expressed as ‘niceness’ and ‘governmentality’, resulting in symbolic exclusion and forced assimilation of people of color. Finally, in rural places, a culture of whiteness uses narratives of ‘pollution’ and ‘parasitism’ to understand often low-income migrants of color, which renders them invisible and reproduces their structural disadvantage in the community. Revealing the subtle and obscure mechanisms through which a culture of whiteness reproduces racial domination in diverse places ultimately provides the key to their undoing and opens the door to the promise of integration.     

论《正义论》中基本善的作用及其存在的必然性

罗尔斯在其义务论的道德哲学中区分了两种善理论,即善的强理论(the thick theory of good)和善的弱理论(the thin theory of good)。前者以良序社会中的正当原则为基础,并在正当优先于善的义务论框架中被广泛讨论。后者则以基本善为核心范畴,以此构建其道德哲学的实践推理基础。不过,他对基本善的设定由于游离于其义务论框架之外而未能得到足够关注。然而,《正义论》对基本善的设定却是理论的必然。该理论在《正义论》中有两个应用层次:首先,它是罗尔斯的道德契约论的推理起点;其次,没有基本善的存在,罗尔斯提出的两个正义原则将难以在道德层面获得足够的稳定性。     

论杜甫的艺术审美观

杜甫不仅是位伟大的诗人,而且是位有着广博高深的艺术鉴赏、品评功力的艺术批评家。书论他以“瘦硬通神”为最高境界,画论他以“画骨传神”为最佳标准,诗论他以“凌云健笔”之风为喜,创作他以“沉郁顿挫”而见长,更多地表现为瘦劲之力、沉雄之气和冷峻之美。杜甫在各门类艺术鉴赏中所共同表现出重瘦劲轻肥俗、重骨弃肉、重神轻形的艺术审美观,是他对魏晋时期的文艺思想和艺术审美观的继承和发扬。     

任意角向模数的介质切伦可夫脉塞

利用自洽线性场理论普遍讨论了相对论电子注中电子在扰动电磁场作用下的三维扰动，在此基础上，对常用的簿环形相对论电子注在介质筒慢波波导中激励的具有任意角向模数的切伦可夫辐射进行了详细的分析，导出了此电子注与慢波系统中具有任意角向模数的波导模工作用的普遍色散方程和波增长率。

90°细弯管内稀疏气固两相流动数值研究

为了研究细弯管内稀疏气固流动条件下颗粒的分布特性,采用离散相模型( DPM)追踪颗粒行为,利用雷诺应力 模型( RSM)模拟气相的湍流流动,考虑了流体一颗粒间的双向耦合作用。通过对颗粒和气体流动行为的分析,得到了气 体压力、速度及颗粒浓度等的分布,研究了细弯管内颗粒流动行为的形成机理。结果表明：细弯管内气相压力沿流动方 向逐渐降低;弯管段内气相最大速度沿管外壁分布;水平段颗粒作下沉运动,弯管段颗粒浓度先分两束,后成单束贴壁流 动,最终杂乱分束,在竖直段彻底弥散化,这是由于各管段不同主要作用力所导致。     

薄膜垂直磁化的理论形成机理

要形成垂直磁化膜,必须要有足够强的垂直磁各向异性能,使得由于磁化而产生的退磁场能量不足以让磁化矢量位于膜面内。在垂直磁记录情形下,针对垂直磁各向异性常数Ku、磁化矢量M与外加磁场Hext成θ角的情况进行了理论分析。在满足磁化矢量与外加磁场方向之间的夹角稳定的平衡条件和稳定性条件的基础上,分析得知:只有满足磁各向异性常数Kn大2πM这一关系的物质才可能形成垂直磁化膜。     

论北随园边连宝其人其诗

北随园边连宝是清诗人中的名家,曾与同时的清代著名诗人袁枚号称南北两随园。其一生科举失意,穷困潦倒,与此相关联,诗风亦清矫冷峭。分析其生平经历及诗歌风格的发现虽然其身后诗名不彰,但其诗歌创作自成一家,理应在清代诗坛占据一席之地。     

宽带光学增透膜的正交设计

镀制多层宽带光学增透膜是改善镜头成象质量,提高光能透过率和协调彩色平衡的必要手段。本文采用二次设计原理,结合正交试验法编制膜系自动设计程序。设计结果表明不但光学性能优良,而且工艺稳定性好,从而可以利用误差来源多、控制精度低的设备镀制出高质量的膜系。文中详述了设计方法并给出程序框图和设计结果。     

Random sections of a sphere

The Bertrand paradox is that, whereas we can define in a unique way a point uniformly at random in the interior of a circle, uniformly random chords can be given a variety of competing specifications. This is generalized to spheres, and the distributions of the uniformly random line sections (chords) and plane sections (disks) are tabulated. This includes the large class which are constructed as uniformly random chords of uniformly random disk sections.
