Linked lives: intergenerational transmission of labour-market pathways between parent dyads and children.

While a vast number of studies confirm the transmission of labour-market disadvantages from one generation to the next, less is known about how parents' interconnected labour-market pathways co-evolve and shape the opportunities and obstacles for their children's future careers. This study uses a multidimensional view of intergenerational transmission by describing the most typical pathways of parents' occupational careers and assesses how these patterns are associated with their children's labour-market outcomes. Drawing on Swedish longitudinal register data, we used multichannel sequence analysis to follow a cohort of people born in 1985 (n = 72,409) and their parents across 26 years. We identified four parental earning models, differentiating between (1) dual earners with high wages, (2) dual earners with low-wage, (3) one-and-a-half-earners and (4) mother as the main breadwinner. Regression analysis shows strong intergenerational transmission among the most advantageous trajectories, with education as a key determinant for young people to become less dependent on family resources. This study stresses the importance of intra-couple perspectives in life course research to understand how inequalities are shaped and preserved across generations.

Becoming a parent: Trajectories of family division of labor in Germany and the United States

The transition to parenthood represents a turning point shaping couples’ arrangements for paid work and housework. Previous studies often examined these changes in isolation, rather than as interrelated trajectories reflecting diverse models of family division of labor. Drawing on data from different-sex couples from the 1984–2019 Panel Study of Income Dynamics and the 1984–2020 German Socio-Economic Panel, this study uses multichannel sequence analysis to identify four and three patterned constellations of family division of labor in the United States and Germany, respectively. 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. Furthermore, among U.S. couples in which the wife has an educational advantage, they are most likely to adopt a partly egalitarian arrangement (equal earnings but not housework) upon becoming parents.

Non-standard employment and underemployment at labor market entry and their impact on later wage trajectories

Using data from the Australian Household, Income, and Labour Dynamics in Australia (HILDA) Survey (2001–2020), we examine how combined patterns of non-standard employment and underemployment in the early career shape later wage trajectories, paying careful attention to gender differences on a representative sample of Australian young men ( N = 470) and women ( N = 497). By combining multichannel sequence analysis and random effects panel models, we make three central findings. First, we identify seven distinct early employment trajectories, with the “standard” career, characterized by stable, full-time permanent jobs in the first 5 years post-education, being the most prevalent. Second, we find that combined patterns of non-standard employment and underemployment during early careers are associated with significant wage penalties. However, these wage penalties diminish within 10 years. Third, enduring and widening wage disparities are found only among youth primarily unemployed or inactive early in their careers. These penalties are particularly pronounced among men, underscoring the influence of the “ideal” worker norm. Overall, integrating underemployed jobseekers into the workforce and addressing gender-based biases should be a priority for policymakers to ensure equal opportunities and fair treatment for all workers in the labor market.

Evolution of the profiles of new psychotropic drug users before and during the COVID-19 crisis: an original longitudinal approach through multichannel sequence analysis using the French health-care database.

The COVID-19 pandemic has had a substantial impact on mental health. An increase in the use of anxiolytic, hypnotic, and antidepressant drugs has been highlighted in France, but with no information at the individual level (trajectories) or concerning patient characteristics. The objective of this study was to describe the profile of new psychotropic drug users since the beginning of the pandemic. We formed two historical cohorts using the Pays-de-la-Loire regional component of the National Health Data System (SNDS): a "COVID-19 crisis cohort" (2020-2021) and a "control cohort" (2018-2019). We analyzed reimbursements for psychotropic medications (anxiolytics, antidepressants, hypnotics, mood stabilizers, and antipsychotics) using a multichannel sequence analysis and performed clustering analysis of sequences. The proportion of new consumers of psychotropic drugs was higher in the COVID-19 crisis cohort (18.0%) than that in the control cohort (16.0%). In the COVID-19 cohort, three clusters of psychotropic drug users were identified, whereas four clusters were identified in the control cohort. A time lag in treatment initiation was observed in the COVID-19 crisis cohort (September) compared with the control cohort (July). This study is one of the first to analyze the profile of psychotropic treatment users during the COVID-19 crisis. Our analysis sheds light on changes in patterns of psychotropic drug use during the COVID-19 pandemic, possibly associated with changes in prescribing conditions and mental health conditions during the crisis. This study also provides an example of the application of an innovative longitudinal analysis methodology in the field of pharmacoepidemiology.

Diverse Early-Life Family Trajectories and Young Children’s Mental Health in the UK

Past research suggests that children from two-parent married families fare better than children from other families on many outcomes. Only fragmented evidence on diverse family trajectories in association with child mental health is available. Using multi-channel sequence analysis and data from the UK Household Longitudinal Study, we jointly capture maternal partnership trajectories and type of father co-residence between birth and age 5. We then assess the association between these family trajectories and child mental health at age 5 and 8 using random effects regression. Children whose trajectories include the entrance of a non-biological father or parental separation have the lowest levels of mental health. However, children of never partnered mothers and those who repartner with the biological father have comparable mental health to children of stably married biological parents. Thus, not all types of family complexity or instability appear to be equally detrimental to children’s mental health.

Work-family trajectories across Europe: differences between social groups and welfare regimes.

Work and family trajectories develop and interact over the life course in complex ways. Previous studies drew a fragmented picture of these trajectories and had limited scope. We provide the most comprehensive study of early-to-midlife work-family trajectories to date. Using retrospective data from waves 3 and 7 of the Survey of Health, Aging and Retirement in Europe (SHARE), we reconstructed work-family trajectories from age 15 to 49 among almost 80,000 individuals born between 1908 and 1967 across 28 countries. We applied multichannel sequence and cluster analysis to identify typical trajectories and multinomial logistic regression models to uncover their social composition. The results revealed six common trajectories. The dominant and therefore standard trajectory represents continuous full-time employment with having a partner and children. Women, the lower educated and persons from conservative and liberal welfare regimes are underrepresented in this trajectory, whereas men, higher educated people and those from social-democratic, Eastern European and Baltic welfare regimes are overrepresented. The other trajectories denote a deviation from the standard one, integrating a non-standard form of work with standard family formation or vice versa. Mothers in a stable relationship generally work part-time or not at all. When mostly in full-time employment, women are more likely to be divorced. Lower educated persons are less likely to have work-family trajectories characterized by full-time work and a non-standard family, yet more likely to be non-employed for large parts of their life with standard family formation. Younger cohorts are underrepresented in non-employment trajectories, but overrepresented in part-time employment trajectories along with a partner and children as well as full-time employment trajectories with divorce. Individuals from Southern European and liberal regimes are more likely to be non-working and self-employed partnered parents and those from social-democratic regimes are more likely to be full-time employed divorced parents. We also found pronounced gender differences in how educational level, birth cohort and welfare regime are associated with work-family trajectories from early to midlife. Our findings highlight the socially stratified nature of earlier-life work-family trajectories in Europe. Potential implications for inequalities in later life are discussed.

Comparison of two approaches in multichannel sequence analysis using the Swiss Household Panel.

Sequence analysis is an established approach to study life courses. When several life domains are considered simultaneously, multichannel sequence analysis (MSA) and the extended alphabet (EA) approach are the most frequently used strategies. We compare these two methods using real data composed of four life domains (cohabitational status, children, professional status, health), and we focus on clustering since sequence analysis usually aims to identify typical patterns in sequences. As professional status trajectories, and potentially their relationship with other domains, proved to be different between men and women, the analyses were run separately by sex. We describe step by step the approach followed and the different criteria to judge the relevance of a typology. Neither of the two approaches is clearly superior, and the typologies obtained with both methods are often close. However, even if MSA is generally easier to use and applies to a broader range of situations, EA can provide original typologies in specific cases and we therefore propose guidelines for choosing between the two approaches depending on the context.

Do Working and Parenting Trajectories Influence Retirement Timing? Evidence From Spain, Using a Sequence Analysis Approach and Focusing on Women

Abstract This paper investigates the association between accumulated experiences in the working and parenting spheres and retirement timing among Spanish women, utilizing data from the Survey of Health, Ageing and Retirement in Europe (SHARE). The study examines whether labor market attachment or cumulative disadvantage characterizes women’s retirement and how these factors relate with the number of children. Firstly, multichannel sequence analysis and cluster analysis were employed to identify distinct work–family life courses from ages 20 to 50. Seven clusters were identified: “Full-time work with 2+ children,” “Out of the labour force and 2+ children,” “Mid-life discontinuity and 2+ children,” “Full-time work and 1 child,” “Full-time work and childless,” “Part-time work and 2+ children,” and “Part-time work or out of the labor force and 1 child.” Secondly, the study examines the association between these identified groups and retirement timing. The results indicate that Spanish women who have experienced more unstable careers characterized by extended periods of inactivity or part-time work, particularly in combination with having 2 or more children, are more likely to retire at a later age compared with women with continuous careers, with or without children. These findings underscore the ongoing challenges of balancing unpaid care work and wage work in Spain, while also revealing notable variations among women.

If unpartnered at the birth of a child, how would you fare? A life-course perspective on contemporary single motherhood

ABSTRACT In this article, we use population-based administrative data and multichannel sequence analysis to investigate the trajectories of single mothers in Norway who had a child while unpartnered in 1993, 2001 and 2008. Our observation period is from 1994 to 2015. This period covers several structural transformations in Norwegian society and changes in family policies and welfare policies concerning single mothers. Furthermore, the period saw the growth of alternatives to the nuclear family as the prevailing normative ideal. Our findings demonstrate both complexity and heterogeneity among single mothers and their trajectories. Even so, the population of this group of single mothers is both younger and have lower education than the comparable population of non-single mothers. Nearly half of the single mothers followed trajectories characterized by strong labour market integration and family re-establishment. The other half followed more precarious trajectories characterized by unemployment and health related benefits. Importantly, age and life stage have strong implications for the labour market and family trajectories. Thus, early parenthood combined with leaving school early increases the probability of following precarious trajectories. The results further suggest that both economic cycles and changing welfare state framework is of great importance for single mother trajectories.

Investigation of the pharmacological treatment patterns of Chinese patients with major depressive disorder under real-world settings using multi-channel sequence analysis.

Despite many treatment guidelines available now, the treatment patterns of major depressive disorder (MDD) in China haven't been well-understood due to complexity and diversity. To describe pharmacological treatment patterns of MDD patients in real-world settings using electronic health records from a major psychiatric hospital in China. MDD patients (18-65 years, ICD-10: F32.x, F33.x) newly initiated single antidepressant (AD) in 2015 were enrolled, the date of first AD prescription during the study period was defined as index date, and eligible patients were followed up to 1 year. Treatment patterns were revealed and analyzed using multi-channel sequence analysis (MCSA), considering patients' chronological sequences (in days) of AD prescription, cumulative treatment step(s), and polypharmacy usage during the follow-up. This study (n = 5,003) identified four types of MDD treatment patterns. The first type (1-time treatment) represents the largest proportion of patients (73.6%, n = 3,686), followed by the second type (6-month consistent treatment) and third type (long-term, consistent treatment) collectively accounted for 20.6% (n = 1,031) of patients, by contrast the last type (long-term, inconsistent treatment) made up the rest 5.7% (n = 286) of patients while exhibiting the most complicated treatments patterns. The choice of AD was dominated by selective serotonin reuptake inhibitors (SSRIs), while treatment duration spent in polypharmacy spanned at 2.8%, 16.4%, 2.0%, and 36.5% over the four types, respectively. Treatment patterns reflecting real-world pharmacological treatment practices of MDD in China were revealed using MCSA. The observed discrepancies between real-world practice and treatment guidelines provided additional insights in improving the clinical management of MDD.

Union formation and fertility amongst immigrants from Pakistan and their descendants in the United Kingdom: A multichannel sequence analysis

Previous work identifies conservative family behaviour amongst Pakistanis in the United Kingdom relative to natives, including earlier marriages, fewer dissolutions, and higher fertility. However, few studies have investigated how fertility and partnership

Women's Employment-Family Trajectories and Well-Being in Later Life: Evidence From France.

Objective: Previous research in various countries has found that employment-family trajectories characterized by early or single motherhood, or weak ties to employment, are associated with poor well-being among older women. Our paper explores whether this differs (1) in France, characterized by a high female employment rate and supportive family policies; (2) across dimensions of well-being. Method: We used the Health and Occupational Itinerary survey to identify 10 common patterns of employment-family trajectories (derived from multi-channel sequence analysis) and analysed their association with six indicators of well-being in 2010 (N = 2882 50-78years old women). Results: Continuous full-time employment is associated with better well-being, except for women who had a first child around 24years old, who reported increased anxiety and lack of support. Discussion: Employed mothers' well-being seems to be protected in a context of family friendly policies, but we identified one group with lower well-being, which merits further study.

Health among workers retiring after the state pension age: a longitudinal and comparative study

BackgroundIn recent decades, many countries have observed increasing labor force participation beyond the state pension age (SPA). However, there is a lack of research on employment beyond SPA and how it relates to older workers’ health. Moreover, there is a need to better understand how institutional factors affect the relationship between older workers’ employment and health. In this study, we examine simultaneous employment and health trajectories over 11 years in 12 countries from Europe and the Americas, and study how these trajectories differ by welfare state regime and level of old-age pension redistribution.MethodsWe used a harmonized pooled-country dataset of 3699 older workers based on four representative panel surveys: the Survey of Health, Ageing and Retirement in Europe (SHARE), the English Longitudinal Study of Ageing (ELSA), the Health and Retirement Survey (HRS), and the Chilean Social Protection Survey (EPS). We conducted multichannel sequence analysis to estimate the types of simultaneous employment–health trajectories, and multinomial regression analysis to examine the relationship between trajectory types and institutional factors.ResultsWe found that late retirement was equally associated with poor and good health. There is also a higher prevalence of late retirement trajectories in combination with poor health in liberal welfare regimes and in countries with lower levels of old-age pension redistribution.ConclusionOur study indicates that nonliberal welfare regimes and redistributive old-age pension policies may be better suited to protect vulnerable workers while providing those in good health with the opportunity to work beyond the SPA.

Employment trajectories and mental health-related disability in Belgium

ObjectivesAn individual’s quality of employment over time has been highlighted as a potential determinant of mental health. With mental ill-health greatly contributing to work incapacities and disabilities in Belgium, the present study aims to explore whether mental health, as indicated by registered mental health-related disability, is structured along the lines of employment quality, whereby employment quality is assessed over time as part of individuals’ labour market trajectories.MethodsUsing administrative data from the Belgian Crossroads Bank for Social Security over 16 quarters between 2006 and 2009, transitions between waged jobs of varying quality (based on dimensions of income, working time, employment stability and multiple jobholding), self-employment, and unemployment are considered among individuals in the labour force aged 30–40 at baseline (n = 41,065 women and 45,667 men). With Multichannel Sequence Analysis and clustering, we constructed ideal types of employment trajectories. Fitting Cox regressions, we then evaluated individuals’ hazard of experiencing a disability from a mental disorder between 2010 and 2016.ResultsOur analysis highlights various gender-specific trajectories. Among both genders, individuals exposed to near-constant unemployment over the initial 4 years showed the highest hazard of subsequent mental health-related disability compared to a group characterised by stable full-time employment, single jobholding, and above-median income. Trajectories involving a higher probability of subsidised and non-standard employment and (potential) spells of unemployment and lower relative income were also strong predictors of cause-specific disabilities. Health selection and confounding might, however, be contributing factors.ConclusionsOur study shows a gradient of mental disorders resulting in a disability along trajectory types. Our findings highlight the predictive power of labour market trajectories and their employment quality for subsequent mental disorder-related disability. Future research should examine the mechanisms, including selection effects in this association.

Gendered work-family life courses and late-life physical functioning: A comparative analysis from 28 European countries.

Combining work and family roles can have beneficial consequences on health but could also result in chronic stress and adverse health outcomes at older ages. This study aimed to examine combined employment, parenthood, and partnership histories of men and women during the childbearing period (ages 15-49), and to investigate the links of these work and family roles with physical functioning later in life. We used data from the Survey of Health, Ageing and Retirement in Europe (SHARE) with retrospective information on employment, parenthood, and partnership histories for 18,057 men and 20,072 women (n = 38,129) living in 28 different countries belonging to six European welfare clusters. We applied multichannel sequence analysis (MCSQA) and hierarchical clustering to group work-family trajectories into 12 clusters for men and 15 clusters for women. We assessed the association between work-family life courses and grip strength by estimating multivariable linear regression models. Delayed work and family transitions, unstable employment, and the absence of combinations of work and family roles between age 15 and 49 were associated with weaker grip strength in later life for both men and women. Results differed by gender and were framed by the welfare context in which gendered work and family responsibilities unfold across individual life courses. The findings make an important contribution to the domain of gender and health in later life and stress the need to engage more with issues related to the mechanisms linking work and family trajectories to poor health in later life.

Does it pay off to specialize? The interplay between educational specificity, level and cyclical sensitivity

This paper investigates how the specificity of the field of study is related to the quality of school-to-work transitions, and whether this relation is moderated by the level of education and the cyclical sensitivity of the field of study. We apply a processual approach and produce a typology of school-to-work transitions based on labor market position and income. This is done with multichannel sequence analysis on register data on school-leavers in the Netherland for the 2009–2010 cohort (N = 182,057). The results confirm that specificity is positively related to the quality of school-to-work transitions in terms of employment and income security. This however mostly holds for the highest levels of upper-secondary vocational education (ISCED 354), and much less for the lower levels of upper-secondary vocational education and tertiary education. In contrast to our expectations, specificity was more often related to positive career outcomes for cyclically sensitive fields of study.

Life-Course Perspective on Personality Traits and Fertility with Sequence Analysis

Abstract We investigate the link between personality traits (PTs) and fertility, accounting for the possible interplay with other key life course events. Using data from German Socio-Economic Panel survey, we build sequence-type representations of fertility, union and job careers between the ages of 20 and 40. We rely on multichannel sequence analysis (MSA) and on the Partitioning around Medoids algorithm to cluster individuals with similar experiences, and relate clusters to PTs via multinomial regression. We also develop a procedure to apply standard and MSA to truncated trajectories. This enables inclusion of individuals whose trajectories were otherwise observed for a limited age span, notably belonging to younger cohorts. We show that PTs relate to these (portions of) life-course trajectories, of which fertility is only one outcome.

Part-time work and health in late careers: Evidence from a longitudinal and cross-national study

In this exploratory study, we examine how older workers' part-time employment and health are associated in four countries promoting this type of employment in late careers but with a different welfare regime: the United States, Germany, Sweden, and Italy. Using data from two large representative panel surveys and conducting multichannel sequence analysis, we identified the most typical interlocked employment and health trajectories for each welfare regime and for three different age groups of women and men. We found that there is more heterogeneity in these trajectories in countries with a liberal welfare regime and among older age groups. Overall, women are more strongly represented in the part-time employment trajectories associated with lower health levels. In countries with a social-democratic or corporatist welfare regime, part-time employment in late careers tends to be associated with good health. Our findings suggest that the combination of a statutory right to work part-time in late careers with a more generous welfare regimes, may simultaneously maintain workers’ health and motivate them to remain active in the labor force.

Scarred by Your Employer? The Effect of Employers’ Strategies on the Career Outcomes of Non-Standard Employment

In this article, we investigate how the strategies employers have for using non-standard employment – screening, workforce adaptability or cost reduction – affect the career outcomes of workers. To investigate this, we use multichannel sequence analysis to produce a typology of employment and income trajectories of workers with non-standard contracts in the Netherlands. The results show that workers starting employment in firms that use non-standard employment as a screening device are most likely to have careers with high levels of employment security. Strong scarring effects on the career are only found for workers who start employment in firms with cost reduction strategies.

Transformer Network Intelligent Flight Situation Awareness Assessment Based on Pilot Visual Gaze and Operation Behavior Data

Situational awareness is the ability of pilots to master flight status, which is of great significance to aviation flight safety and flight effect. According to the information processing model, the pilot’s main steps of processing information are feeling, perception and execution. There are many problems in situation awareness analysis guided by visual gaze, such as large analysis deviation and high delay due to various influencing factors and complex characteristics. In order to solve this problem, this paper proposes a situation awareness assessment method based on artificial intelligence neural network and integrating visual gaze and flight control. First, this paper carries out simulated flight training experiments for flight cadets, and collects the data of eye movement, line of sight tracking, flight control and flight parameters of pilot cadets. Then, aiming at the flight subjects, a situation awareness analysis method based on events is established, and the situation awareness state in the experiment is evaluated and analyzed through the flight parameter data. Then, the visual gaze and flight control data are sliced in the unit of situational awareness events, and the data set is constructed. Finally, this paper designs a multi-channel sequence data classification and analysis model based on transformer, in which the situation awareness characteristics of visual gaze and operation behavior are analyzed through the attention mechanism. The experimental results show that the accuracy of situation awareness classification of the designed neural network model to the experimental data set is 96%, and can classify and evaluate the pilot’s situation awareness state in 5[Formula: see text]s.
