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.     

Partial Identification of Economic Mobility: With an Application to the United States

Abstract

The economic mobility of individuals and households is of fundamental interest. While many measures of economic mobility exist, reliance on transition matrices remains pervasive due to simplicity and ease of interpretation. However, estimation of transition matrices is complicated by the well-acknowledged problem of measurement error in self-reported and even administrative data. Existing methods of addressing measurement error are complex, rely on numerous strong assumptions, and often require data from more than two periods. In this article, we investigate what can be learned about economic mobility as measured via transition matrices while formally accounting for measurement error in a reasonably transparent manner. To do so, we develop a nonparametric partial identification approach to bound transition probabilities under various assumptions on the measurement error and mobility processes. This approach is applied to panel data from the United States to explore short-run mobility before and after the Great Recession.     

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。

Projective Identification as a Contributor to Domestic Violence

Many explanations have been given as to why men batter. Rarely are deep unconscious intrapsychic processes identified as contributing reasons. One way that violent men may use their partner to fill emotional needs is through the primitive defense of projective identification. Projective identification may be invoked by men to induce the other partner to carry split off threatening parts of the self that are too anxiety provoking to retain. The occurrence of projective identification could therefore be an important intrapsychic and interpersonal dynamic that contributes to the escalation of tension prior to the violent episode.

Estimation of Metabolic Rate Constants in PBPK‐Models from Liver Slice Experiments: What Are the Experimental Needs?

A mechanistic model is presented describing the clearance of a compound in a precision-cut liver slice that is incubated in a culture medium. The problem of estimating metabolic rate constants in PBPK models from liver slice experiments is discussed using identifiability analysis. From the identifiability problem analysis, it appears that in addition to the clearance, the compound's free fraction in the slice and the diffusion rate of the exchange of the compound between culture medium and liver slice should be identified. In addition, knowledge of the culture medium volume, the slice volume, the compound's free fraction, and octanol-water-based partition between medium and slice is presupposed. The formal solution for identification is discussed from the perspective of experimental practice. A formally necessary condition for identification is the sampling of parent compound in liver slice or culture medium. However, due to experimental limitations and errors, sampling the parent compound in the slice together with additional sampling of metabolite pooled from the medium and the slice is required for identification in practice. Moreover, it appears that identification results are unreliable when the value of the intrinsic clearance exceeds the value of the diffusion coefficient, a condition to be verified a posteriori.
