Field of study variation throughout the college pipeline and its effect on the earnings gap: Differences between ethnic and immigrant groups in Israel

This study demonstrates the analytical leverage gained from considering the entire college pipeline—including the application, admission and graduation stages—in examining the economic position of various groups upon labor market entry. The findings, based on data from three elite universities in Israel, reveal that the process that shapes economic inequality between different ethnic and immigrant groups is not necessarily cumulative. Field of study stratification does not expand systematically from stage to stage and the position of groups on the field of study hierarchy at each stage is not entirely explained by academic preparation. Differential selection and attrition processes, as well as ambition and aspirations, also shape the position of ethnic groups in the earnings hierarchy and generate a non-cumulative pattern. These findings suggest that a cross-sectional assessment of field of study inequality at the graduation stage can generate misleading conclusions about group-based economic inequality among workers with a bachelor’s degree.     

民族互嵌社区精准治理的理论向度与实践路径——以贵州省兴义市S街道社区为例

民族互嵌社区是中华民族多元一体格局空间场域延展的实践形态,是对“各民族相互嵌入式的社会结构和社区环境”这一时代命题的现实阐释。现代城市社区功能的集聚和细化为民族互嵌的再造及重释提供了场域空间,由于民族互嵌社区具有公共性、聚合性和互动性的本质特征,从而形成了立体化嵌套结构,催生出精准互嵌理论和实践的“双重愿景”:理论层面,要深刻把握民族互嵌社区精准治理的目标向度、方法向度、内容向度;实践层面,要精准识别民族互嵌社区的场域情境,以智能技术描绘民族互嵌过程的“全景图”和“晴雨表”,通过社区制度体系的精准供给,提升民族互嵌社区精准治理的效能。     

民族记忆与文化基因--瑶族民族记忆中“中华民族共同体”文化基因的表征及其价值阐释

民族记忆既是传承民族文化基因的载体,也是彰显民族文化基因的重要文化表征。民族记忆作为延续民族历史和文化基因的内在根基,通过传承民族历史文化、建构民族身份、塑造民族形象等形式传承和彰显民族文化基因的内在特征。以瑶族为代表的少数民族文化基因是中华民族文化基因的重要组成部分,深入挖掘瑶族民族记忆中蕴含的“中华民族共同体”文化基因,并阐释其内在的价值与意义,对培育和铸牢我国各民族的“中华民族共同体”意识有着重要的理论价值与现实意义。

福建宁德畲族(聚居区)文化遗产保护与利用的调查报告

福建宁德畲族文化作为中华畲族文化的主源头之一,在团结与凝聚当地和国内外的畲族同胞,增进人们对畲族历史文化和现实了解方面发挥了不可替代的纽带作用,它与聚居区内景色秀丽的山水风光相映成趣,具有潜力巨大的旅游价值与产业价值。但近期以来,该地畲族传统文化也面临着逐渐失传的现实危机。抓紧实施抢救与发展畲族文化遗产系统工程的各项具体工作,对于继承畲族优秀传统文化,促进地方自然生态、文化生态与经济的和谐发展具有重要的意义。     

萨满教与北方少数民族帝王--兼论中国历史上的政治宗教

在中国历史上大多数少数民族帝王和萨满教发生过密切关系。北方少数民族建立的巫王合一、巫王合作型的政权形态是中国历史上政治与宗教有机结合的产物。在这种政权形态中 ,王权和神权结合在一起 ,但二者相互干预 ,并在双向互动过程中发生作用。萨满巫师和北方少数民族帝王合伙建构了中国历史上的一种典型的政治宗教形态。建立在萨满教观念基础上的北方少数民族政治宗教的核心是“王权神授”和“汗权天授”思想。这与中原王朝历代统治者宣扬的“君权神授”观念基本一致。     

Sampling Strategies for Toxic Air Contaminants

Annual concentrations of toxic air contaminants are of primary concern from the perspective of chronic human exposure assessment and risk analysis. Despite recent advances in air quality monitoring technology, resource and technical constraints often impose limitations on the availability of a sufficient number of ambient concentration measurements for performing environmental risk analysis. Therefore, sample size limitations, representativeness of data, and uncertainties in the estimated annual mean concentration must be examined before performing quantitative risk analysis. In this paper, we discuss several factors that need to be considered in designing field-sampling programs for toxic air contaminants and in verifying compliance with environmental regulations. Specifically, we examine the behavior of SO2, TSP, and CO data as surrogates for toxic air contaminants and as examples of point source, area source, and line source-dominated pollutants, respectively, from the standpoint of sampling design. We demonstrate the use of bootstrap resampling method and normal theory in estimating the annual mean concentration and its 95% confidence bounds from limited sampling data, and illustrate the application of operating characteristic (OC) curves to determine optimum sample size and other sampling strategies. We also outline a statistical procedure, based on a one-sided t-test, that utilizes the sampled concentration data for evaluating whether a sampling site is compliance with relevant ambient guideline concentrations for toxic air contaminants.     

Surname analysis for estimating local concentration of Hispanics and Asians

Surname analysis is a potentially useful technique for identifying members of particular racial, ethnic, or language communities within a population. We review the existing state of the art for identifying persons of Hispanic or Asian origin, based on surnames distinctive of each group. We describe the logic of surname analysis, profile several available surname dictionaries, and illustrate their applications in local redistricting. Results of our ongoing validation studies suggest promising future directions for improving accuracy and broadening applications.This article is based on a paper presented at the annual Population Association of America meetings at Cincinnati, 1 April 1993.     

民族地区构建和谐社会应加强对传统多元生态文化的利用和改造

“人与自然和谐相处”是社会主义和谐社会的六个基本特征之一,民族地区构建社会主义和谐社会必须考虑到传统多元生态文化的功能。在开放的、以市场经济为主导的现代社会生态经济系统下,传统多元生态文化的约束力远不如在传统社会生态经济系统中那么有效、广泛。民族地区只有在维护自身生态经济系统可持续运作的基础上,进一步加强对传统多元生态文化的利用和改造,才能充分发挥生态文化的协调功能。因此,民族地区应当在继续维护传统生态文化的多元性、科学性和合理性的同时,根据现行社会生态经济系统的特征,把其改造成为“强生态文化”,构建以科学发展观为基础,具有较强约束力的、适应现行社会生态经济系统的、协调人与自然关系的,包括精神、物质、制度层面的整体文化体系。
