Racial diversity, minority concentration, and trust in Canadian urban neighborhoods

Using a sample of 42,329 respondents nested within 4254 Canadian urban neighborhoods, this study demonstrates the conceptual and empirical importance of making a distinction between neighborhood racial diversity and minority concentration, and examines how each is uniquely associated with trust. Our analysis shows that at a given level of racial minority concentration, Whites are more trusting when their minority neighbors are more evenly distributed across racial minority groups. Meanwhile, Whites are less trusting as the neighborhood share of racial minorities increases. Overall, the effect of racial minority concentration tends to prevail over that of racial diversity.     

西昆仑出山径流尼雅河与尼雅聚落

西昆仑山脉出山径流尼雅河,系依赖上游源区冰川融化及山区降雨才得以形成.进入平川区、尾闾地区后,在塔克拉玛干沙漠气象条件及其下垫面作用下,尼雅河水渐渐消失.一百年来的尼雅遗址考察、考古及历史研究成果丰硕,尼雅从聚落到废墟的演变过程,反映了尼雅河来水等水源逐渐匮乏的事实,魏晋后尼雅行政建置丧失于交通价值的下降,喀帕克阿斯干村以北居民点,则最后废弃于彻底无水接济.

《西游记》中阿傩的冤案

《西游记》九十八回有一个阿傩向唐僧师徒索要"人事"的情节,这被许多人认为是作者表现阿傩索贿并进而讽刺佛教的重要证据。但从《西游记》的抑道扬佛倾向、从该情节所体现出的佛教教理教义、从作品的艺术构思与主题表现等方面来看析,作品中这个索要"人事"的情节,并非是对佛教的讽刺,而是作品整个佛教思想体系中的一个非常重要的组成部分,有着深刻的佛教文化内涵。     

"异化理论"中的自由观透视——重读《1844年经济学哲学手稿》

<1844年经济学哲学手稿>在异化劳动理论的阐释中,涵摄着马克思自由观的基本思想和基本逻辑.当我们在异化理论的透视中领悟这种自由观时,得出的结论是马克思在确立自由观时遵循着理性人与自由人的理论前提预设.站在当代角度上重新审视马克思理论的前提及由此演绎出的理论内容,是我们力图穿越时空界限、走进马克思的新的尝试.

2013年西方马克思主义研究述评

坚持和发展马克思主义,必须重视加强对西方马克思主义的研究。2013年学界对西方马克思主义的研究主要集中在人物、流派、问题等个案研究方面,研究水平参差不齐,总体研究和比较研究偏少,研究方法也不丰富。为此,应从不同的视角开展对西方马克思主义的研究,为马克思主义基本理论的研究提供依据和支持,从而维护和发展马克思主义。     

梁启超群治文学观初探

梁启超是中国近代文化转型过程中最具代表性的人物。20世纪初期,梁启超引进西方文化观念,首倡近代多种文体的革新,提出了著名的"群治社会构想",反映在文学思想上主要包括四个方面,即聚合现代民族精神,展示历史进化趋势,"言文一致"语体风格和构建市民文化空间。梁启超"群治"文学观的提出及其有益实践对启蒙国人思想、推进中国文学发展和社会进步,都具有重要意义。     

Business Cycles,Medicaid Generosity,and Birth Outcomes

Birth outcomes influence many aspects of later life health and wellbeing, making healthcare access during pregnancy a policy priority. Low-income mothers often depend on Medicaid, for which eligibility is determined by their income relative to state eligibility thresholds. The prevalence of adverse birth outcomes is known to exhibit cyclical variation, due in part to changes in the composition of women giving birth in response to changing economic conditions. However, cyclical variation in adverse birth outcomes also varies with respect to Medicaid eligibility thresholds. Our analysis uses birth-records data for 2000 through 2013, aggregated into 173,936 county-by-quarter observations and linked to county-level unemployment rates and state-level parental Medicaid thresholds. Using fixed-effects negative binomial models, we examine the role of Medicaid generosity in influencing birth outcomes across business cycles. We test for interactions between Medicaid and unemployment, hypothesizing that the negative effects of recessions are worse where Medicaid thresholds are more restrictive. We find that higher Medicaid generosity dampens the negative effects of recessions on birth outcomes. The extent to which Medicaid interacts with unemployment also varies according to the age and race composition of mothers; in particular, Black mothers are both most affected by unemployment and most responsive to Medicaid generosity. Given current concerns about racial gaps in both infant and maternal mortality, our findings suggest that Medicaid may be an important feature of a strategy to close gaps in the prevalence of adverse birth outcomes across racial groups, especially during bust years.     

城市空间关系问题研究——以黄冈与武汉城市圈内周边城市空间关系为例

城市化的快速发展使得城市空间关系不断变化,如何准确界定城市空间关系对城市战略选择至关重要。本文在总结前人对城市空间关系研究的基础上,将城市空间关系分为依附型、竞争型、共生型、异质型四种。进而在此基础上以黄冈为案例,研究黄冈与武汉城市圈内周边城市的关系,并提出黄冈的定位和发展战略。
