This paper uses a life-history grid to collect narrative data on the labor market transitions of young people aged 20–34 (n = 98) in order to analyze the support provided by relatives in the Barcelona Metropolitan Area. Drawing on social capital theory, we explore these mechanisms by analysing the flow of resources within family networks (one-step social capital) and how relatives mediate with other agents in the labor market (two-step social capital). Hence, we address the diversity of material, symbolic and informational resources provided by relatives during labor transitions in order to understand the mechanisms involved in the intergenerational reproduction of occupation inequalities. Although the ‘strength of weak ties’ thesis usually associates the use of family networks among disadvantaged groups, our results show that the mobilization of relatives is equally important in upper-class background, in which mechanisms such as nepotism and influence on third-party employers are activated. Among the working classes, family ties help job seekers to reach non-redundant connections in the secondary segment of the labor market. The article contributes by providing a detailed map of the roles played by relatives in a southern European context characterized by precariousness and unemployment.

This paper proposes a conceptualization of the life course as a set of behavioral processes characterized by interdependencies that cross time, life domains, and levels of analysis. We first discuss the need for a systematized approach to life course theory that integrates parallel and partially redundant concepts developed in a variety of disciplines. We then introduce the ‘life course cube,’ which graphically defines and illustrates time-domain-level interdependencies and their multiple interactions that are central to understanding life courses. Finally, in an appendix, we offer a formal account of these interactions in a language that can be readily adopted across disciplines. Our aim is to provide a consistent and parsimonious foundation to further develop life course theories and methods and integrate life course scholarship across disciplines.

In this article, we propose a methodology for the validation of sequence analysis typologies based on bootstraps. The method works by comparing the quality of the obtained clustering with the quality obtained by clustering similar but unstructured data. Several models are proposed in order to test the different structuring aspects of the sequences that are important in life course research, namely sequencing, timing and duration. The framework is extended to multichannel sequence analysis by looking at the structure stemming from the association between the channels.

The aim of this article is to explore the links between former guest workers’ attitudes toward return, as they approach retirement age, and ambivalence. More specifically, we seek answers to the following two questions: Do older immigrants modify their intentions toward return around the retirement period? If the answer is positive, we then ask: To which factors are these changes related when looking at intentions to return both before and after retirement? These questions have seldom been analyzed in the sociological literature, and their relation to ambivalence has not yet really been explored. After considering the state of the art, both from a sociology of migration perspective and through a life-course approach, we analyze empirically how older immigrants deal with the question of return. Our data come from a representative survey of approximately 300 older immigrants from Southern Europe (Italy, Portugal, and Spain), aged between 65 and 79 and living in urban Switzerland. Our findings show that (1) while a significant proportion of Italian and Spanish older migrants give up the idea of returning definitively to their country of origin and decide to establish their main residence in Switzerland, among the Portuguese, a significant minority wanted to return before retirement and are still planning to return, expecting to recover full citizenship in their “home” country; (2) changes with respect to return intentions mainly concern former blue-collar workers and white-collar employees; and (3) older immigrants who do not see migration as a positive decision demonstrate more ambivalence about return.

\textbf\textitBackground: Cognitively stimulating activities contribute to the accumulation of cognitive reserve that is proposed to be instrumental for maintaining cognitive functioning in aging. Adopting a novel, more general conceptual perspective including models of vulnerability, we argue that cognitive reserve may modify the longitudinal association between perceived stress and the rate of subsequent decline in executive functioning. \textbf\textitObjective: The present study set out to investigate the longitudinal relationship between perceived stress and subsequent decline in executive functioning over 6 years as measured through performance changes in the Trail Making Test (TMT) and whether this longitudinal relationship differed by key markers of cognitive reserve (education, occupation, and leisure activities), taking into account age, sex, and chronic diseases as covariates. \textbf\textitMethods: We used latent change score modeling based on longitudinal data from 897 older adults tested on TMT parts A and B in two waves 6 years apart. Mean age in the first wave was 74.33 years. Participants reported information on perceived stress, education, occupation, leisure activities, and chronic diseases. \textbf\textitResults: The longitudinal relationship between greater perceived stress in the first wave of data collection and steeper subsequent decline in executive functioning over 6 years was significantly reduced in individuals who had pursued a higher frequency of leisure activities in the first wave. \textbf\textitConclusion: The longitudinal relationship between perceived stress and subsequent decline in executive functioning may be attenuated in individuals who have accumulated greater cognitive reserve through an engaged lifestyle. Implications for current cognitive reserve and gerontological research are discussed.

People's perceptions of benefits and risks play a key role in their acceptance or rejection of medical interventions, yet these perceptions may be poorly calibrated. This online study with N = 373 adults aged 19–76 years focused on unrealistic optimism in the health domain. Participants indicated how likely they were to experience benefits and risks associated with medical conditions and completed objective and subjective numeracy scales. Participants exhibited optimistic views about the likelihood of experiencing the benefits and the side effects of treatment options described in the scenarios. Objective and subjective numeracy were not associated with more accurate ratings. Moreover, participants’ underestimation of the risks was significantly greater than their overestimation of the benefits. From an applied perspective, these results suggest that clinicians may need to ensure that patients do not underestimate risks of medical interventions, and that they convey realistic expectations about the benefits that can be obtained with certain procedures.
