However, there are also concerns about a preoccupation with 'impact' in academia, which may result in a narrow focus on applied research. The most common definitions of impact (for example, UK Research Excellence Framework) emphasise generating measurable change outside of academia. However, this may overlook other important endeavours, such as influencing discourse and development of theory. The implicit assumption that single research projects will trigger measurable policy change is often unrealistic. Data infrastructures are also expected to demonstrate their 'impact', yet existing definitions are levied at the individual researcher or substantive projects. Such definitions do not account for the additional assumptions required for infrastructure to be impactful, and arguably, in their current form are not fit for purpose in demonstrating the full contribution of longitudinal and life course studies to society. We argue that broader definitions of impact should be considered for longitudinal studies and data infrastructure, that account for the importance of 'influence', and recognise the many and multifaceted contributions of longitudinal and life course research. Here we aim to (1) review definitions of impact in the context of longitudinal and life course studies, using UK national cohorts as a case studies; (2) to provide a working definition appropriate for longitudinal research, that incorporates 'influence'; and (3) to consider approaches that can be utilised to track impact.</p>","PeriodicalId":45988,"journal":{"name":"Longitudinal and Life Course Studies","volume":" ","pages":"1-18"},"PeriodicalIF":1.2,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144486541","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this context, one would expect that the population of childless women has recently become more heterogeneous. In particular, one would suspect a process of polarisation with a growing distinction between women who are unable to give birth and women who forgo motherhood for one reason or another. We investigate this supposed polarisation within the framework of the life course approach. We examine the childless Indian women's partnership trajectories and their associated socioeconomic profiles. Data was extracted from the fourth round (2015-2016) of the National Family Health Survey. A total of 8,997 women aged 36-49 who have not given birth by age 36 were studied. The analysis consisted of three parts: a sequence analysis, a cluster analysis, and a multinomial regression. Results confirm childlessness' polarised experience, along with a real heterogeneity of partnership trajectories. Indian childless women come from diverse socioeconomic backgrounds, and their life courses reflect a continuum of different realities in terms of social norms and decision-making power. In particular, trajectories without any relational event or with extramarital sexual activity are observed among the most educated women, suggesting that their childlessness may be related to factors other than infertility. By describing the heterogeneity of their backgrounds and profiles, our findings challenge the uniform representation of childlessness in India. In doing so, this article participates in the expansion of research on non-parenthood in non-Western populations and highlights the contribution of the life course approach.</p>","PeriodicalId":45988,"journal":{"name":"Longitudinal and Life Course Studies","volume":" ","pages":"1-30"},"PeriodicalIF":1.2,"publicationDate":"2025-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144486570","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We extend this literature by asking whether socioeconomic status moderates the association between child genotype and cognitive skills among racialised and ethnicised minorities in the United States. Hence, what we study is whether high socioeconomic status conveys an equal advantage when it comes to the relationship between genotype and cognitive skills. We use data from the Future of Families and Child Wellbeing Study. Using molecular genetic data, we construct a polygenic index for educational attainment and test whether the association between this index and children's cognitive skills is moderated by maternal education and household income in two principal component defined ancestry groups: African ancestries (n=1,551) and Latinx ancestries (n=890). The polygenic index for educational attainment is positively associated with cognitive skills in both groups. In the African ancestries group, this association does not differ by socioeconomic status. In the Latinx ancestries group, the results are mixed. Because our samples are likely underpowered to detect genotype-socioeconomic interactions, our results should be considered suggestive until larger samples of diverse ancestries are available. Advances in genetic research have been skewed towards European ancestry populations, and the broader implication of our study is to eliminate this bias through the collection of large, diverse genotype samples and measuring their genotypes with arrays designed for multi-ancestry populations.</p>","PeriodicalId":45988,"journal":{"name":"Longitudinal and Life Course Studies","volume":"16 2","pages":"199-227"},"PeriodicalIF":1.2,"publicationDate":"2025-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144486574","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Work-family trajectories are conceptualised by considering individual- and household-level explanations of poverty. Taking a life course perspective, the study explores sequences of labour market attachment, the extent of low-wage receipt and the needs-to-resource ratio in households across eight years. Methods combine multichannel sequence analysis to identify four clusters of work-family trajectories, and linear regressions to link these clusters to the cumulated length of poverty experiences and the average distance from the at-risk-of-poverty threshold across eight years. Findings reveal that most work-family trajectories among working-age households with poverty experience are dominated by low household work intensity and the presence of children, with trajectories of low-wage receipt forming less prominent patterns. Household histories of low work intensity are linked to increased poverty duration and severity. This relation is even stronger for households that simultaneously experience a high needs-to-resource ratio or frequent low-wage receipt, emphasising the interplay between these two factors and household work intensity. High household work intensity reduces poverty persistence the most, with education identified as an important contextual factor mitigating poverty persistence. Findings suggest to reduce poverty persistence by supporting higher work intensity and regular employment in households with poverty experiences by addressing what prevents individual employment, such as upskilling or reskilling along individual strengths. Such initiatives are particularly important to decrease poverty persistence in families with children.</p>","PeriodicalId":45988,"journal":{"name":"Longitudinal and Life Course Studies","volume":" ","pages":"1-24"},"PeriodicalIF":1.2,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144486572","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
