The art of choosing the right tram – A study of urban segregation, choice of school and young people’s life plans When discussing barriers to integration and young people’s choice of school, research often focuses on language skills, cultural capital, supportive environments and other more obvious, distinct and material aspects that have an impact on educational achievement. In the present study, we have instead chosen to look at how young immigrants construct their inner career landscapes and life-plans, and how this relates to their perception of ethnicity, neighbourhood and identity. The sample used here consists of altogether twenty individuals. The interviews were used to explore certain designated dimensions and processes. All interviews were conducted in the school environment, in classrooms and other locations. The students attended two different inner-city schools. A narrative-sociological approach is used in the analysis. The young people’s perceptions and narratives are analysed in relation to concepts such as: territorial stigmatization, identity, self-perception and modifications of life plans. The findings show that the feelings of otherness which originates in housing conditions, experiences of exclusion and the everyday life of many immigrants, are transposed into the school area and transformed into strategies and life plans.

BACKGROUND: Whether the type of dietary fat could alter cardiometabolic responses to a hypercaloric diet is unknown. In addition, subclinical cardiometabolic consequences of moderate weight gain require further study. METHODS AND RESULTS: In a 7-week, double-blind, parallel-group, randomized controlled trial, 39 healthy, lean individuals (mean age of 27±4) consumed muffins (51% of energy [%E] from fat and 44%E refined carbohydrates) providing 750 kcal/day added to their habitual diets. All muffins had identical contents, except for type of fat; sunflower oil rich in polyunsaturated fatty acids (PUFA diet) or palm oil rich in saturated fatty acids (SFA diet). Despite comparable weight gain in the 2 groups, total: high-density lipoprotein (HDL) cholesterol, low-density lipoprotein:HDL cholesterol, and apolipoprotein B:AI ratios decreased during the PUFA versus the SFA diet (-0.37±0.59 versus +0.07±0.29, -0.31±0.49 versus +0.05±0.28, and -0.07±0.11 versus +0.01±0.07, P=0.003, P=0.007, and P=0.01 for between-group differences), whereas no significant differences were observed for other cardiometabolic risk markers. In the whole group (ie, independently of fat type), body weight increased (+2.2%, P<0.001) together with increased plasma proinsulin (+21%, P=0.007), insulin (+17%, P=0.003), proprotein convertase subtilisin/kexin type 9, (+9%, P=0.008) fibroblast growth factor-21 (+31%, P=0.04), endothelial markers vascular cell adhesion molecule-1, intercellular adhesion molecule-1, and E-selectin (+9, +5, and +10%, respectively, P<0.01 for all), whereas nonesterified fatty acids decreased (-28%, P=0.001). CONCLUSIONS: Excess energy from PUFA versus SFA reduces atherogenic lipoproteins. Modest weight gain in young individuals induces hyperproinsulinemia and increases biomarkers of endothelial dysfunction, effects that may be partly outweighed by the lipid-lowering effects of PUFA.
