The hidden costs of ethnic conflict - decomposing trends in educational outcomes of young Kosovars

The authors examine the impact of ethnic segmentation in education on educational outcomes. Between 1991 and the late 1990s, the Albanian Kosovar population received education services in an informal system parallel to the official one. Using the 2000 Kosovo LSMS Survey data, the authors exploit cohort differences in exposure to the parallel system to estimate its effects among Albanian youth. The first (untreated) cohort includes individuals who entered secondary education before 1991 when the"parallel"education system was initiated. The second (treated) cohort includes individuals who entered secondary school in the last ten years under the ethnically segmented education system. To disentangle the effects of the changing system and economic environment, and the changes in the characteristics of the population, a Oaxaca-type decomposition is used. The results suggest that the past decade of ethnic tension has claimed a substantial toll on the educational outcomes of young male Albanian Kosovars. In addition to declines in enrollment rates in secondary education, those who are enrolled are expected to complete one less year of education. However, secondary school enrollment for girls increased during the parallel system, but with a sharp decline in the expected number of years completed.Primary Education,Public Health Promotion,Teaching and Learning,Curriculum&Instruction,Health Monitoring&Evaluation,Primary Education,Curriculum&Instruction,Gender and Education,Teaching and Learning,Health Monitoring&Evaluation

Single-cell analysis of early progenitor cells that build coronary arteries

International audienceArteries and veins are specified by antagonistic transcriptional programs. However, during development and regeneration, new arteries can arise from pre-existing veins through a poorly understood process of cell fate conversion. Here, using single-cell RNA sequencing and mouse genetics, we show that vein cells of the developing heart undergo an early cell fate switch to create a pre-artery population that subsequently builds coronary arteries. Vein cells underwent a gradual and simultaneous switch from venous to arterial fate before a subset of cells crossed a transcriptional threshold into the pre-artery state. Before the onset of coronary blood flow, pre-artery cells appeared in the immature vessel plexus, expressed mature artery markers, and decreased cell cycling. The vein-specifying transcription factor COUP-TF2 (also known as NR2F2) prevented plexus cells from overcoming the pre-artery threshold by inducing cell cycle genes. Thus, vein-derived coronary arteries are built by pre-artery cells that can differentiate independently of blood flow upon the release of inhibition mediated by COUP-TF2 and cell cycle factors
