Periods of life densely populated with critical events may translate into an acute resource drain, affecting long-term wellbeing more strongly than if the same events were sparsely distributed. We investigate how the co-occurrence of critical events and their concentration in time influence life satisfaction in later life. To do so, we construct a novel indicator, the Concentration Index, based not only on the number but also on the time lag between occurrences. Using retrospective information on critical events in family, work, health, and residential trajectories in Switzerland, we show that the higher the concentration in time of critical events is, the stronger their negative long-term relation to wellbeing, net of sociodemographic characteristics, the total number of events ever experienced, and the time since the last event. Furthermore, relevant gender and social origin differences emerged with a stronger negative association with wellbeing among men and respondents from low socioeconomic backgrounds. Our work clearly shows that simply counting the number of events gives only a partial and potentially inaccurate measure of the complexity of the life course and its relationship with quality of life. Not only how many events experienced matter but also the spacing between them.</p></div>","PeriodicalId":47126,"journal":{"name":"Advances in Life Course Research","volume":"61 ","pages":"Article 100616"},"PeriodicalIF":3.4,"publicationDate":"2024-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1569490924000273/pdfft?md5=1e57a13f853d6344b34c1f887180ee7a&pid=1-s2.0-S1569490924000273-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140950840","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, although the increase in the integration rates of young Arab-Palestinian women into the higher education system, as girls belonging to a minority group with traditional structures, they are expected to prioritize family and community expectations over personal aspirations. This study focuses on art projects of female Arab-Palestinian college students in Israel, which serve as a prism for detecting cultural perceptions of pathways to entering adulthood among this population today. These topics are central themes in the projects in question. Working on these projects forced the students to profoundly contemplate their life stage - being engaged or newly married and young mothers. The aim of the study was to decode the artworks in order to explore the students’ feelings and thoughts on a topic rarely considered through the eyes of the young women themselves. The study provides a nuanced examination of the social processes that young educated Arab-Palestinian women experience in the current family structure. By analysing the projects using visual tools from semiotics and art history, along with verbal texts provided by the students, we assert that these projects serve as a crucial avenue for students’ self-expression regarding topics seldom addressed. Even though the projects cannot be understood as critical of traditional gender expectations, we did find some interesting voices of unease regarding them. The move from their parents' home to their new one is widely described as difficult, where sadness and concern about the future are highly noticeable. In addition to accepting the stages of marriage and motherhood with joy and excitement, they also express fear and hesitation. This tension between fulfilling their expected roles and being unsure and hesitant about them exists in the projects. We claim that even if implicit and careful, these signs are important to recognize. However, it seems that higher education has failed to significantly undermine patriarchal and gender expectations.</p></div>","PeriodicalId":47126,"journal":{"name":"Advances in Life Course Research","volume":"60 ","pages":"Article 100614"},"PeriodicalIF":3.4,"publicationDate":"2024-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140946044","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unhealthy weight gains following parental separation are more pronounced among female children and those with lower-educated and non-White parents.

These constellations differ in women’s and men’s respective contributions to household earnings and their relative participation in housework, spanning from one year before to ten years after the birth of a first child. National differences are found in the identified constellations, their prevalence, and the role of couples’ conjoint education in shaping these constellations. In both countries, couples in which the husband has an educational advantage are most likely to transition to a traditional arrangement. However, only in the U.S. do couples with both partners holding a college degree also tend to enter a traditional arrangement.

There is also little research that assesses the multiple domains of social isolation across the lifecourse and between generations in a holistic way accounting for different contexts. By applying a multi-context, multi-domain framework of social isolation to 5 successive British birth cohorts, we provide conceptual and empirical understanding of social isolation trajectories across the lifecourse and identify potential generational and sex differences in trends. Where data were available, comparable social isolation indicators were generated to enable lifecourse trajectories and cross-generational trends to be explored. Information on isolation was available across the following relational contexts: household i.e., living alone; partnership, family and friends outside the household; education and employment networks; and community engagement. Trajectories were modelled stratified by sex using a multilevel growth curve framework. Data were analysed from 73,847 individuals (48.5% female), in 5 successive cohorts born in 1946 (N = 5,362), 1958 (N = 16,742), 1970 (N = 16,950), 1989-90 (N = 15,562), and 2000–01 (N = 19,231). Exploring a range of social isolation indicators across several contexts provided a nuanced picture of social isolation across the lifecourse and between generations in the UK, with no consistent pattern of increased or decreased isolation over time. For example, more people are living alone, less women are out of education and employment in midlife, more people are volunteering, but fewer people regularly engage in religious activity. It therefore highlights the need to focus on a range of social isolation indicators across contexts to understand how people compensate for specific types of isolation, and to understand structural differences in social configurations in the UK, which may not only define the timing and sequencing of life transitions but also social isolation.</p></div>","PeriodicalId":47126,"journal":{"name":"Advances in Life Course Research","volume":"60 ","pages":"Article 100613"},"PeriodicalIF":3.4,"publicationDate":"2024-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140403660","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using longitudinal data from the German Socio-Economic Panel and models with entropy balancing and sibling fixed effects, I explore the heterogeneous effects of family transitions during early and middle childhood on academic secondary school track attendance, grades and aspirations. I find that family transitions only reduce the academic school track attendance among children of less educated parents living in stepfamilies or with a single mother after parental separation, and among children of highly educated fathers living in single-mother families. The mechanisms that partly explain these effects relate to reduced income and exposure to poverty after parental separation. The findings underscore the importance of considering the stepparent's educational level, indicating that the adverse consequences of parental separation on educational outcomes are mitigated when a highly educated stepfather becomes part of the family.
