In this article the authors draw attention to the most recent and promising developments of sequence analysis. Taking methodological developments in life course sociology as the starting point, the authors detail the complementary strength in sequence analysis in this field. They argue that recent advantages of sequence analysis were developed in response to criticism of the original work, particularly optimal matching analysis. This debate arose over the past two decades and culminated in the 2000 exchange in Sociological Methods & Research. The debate triggered a "second wave" of sequence techniques that led to new technical implementations of old ideas in sequence analysis. The authors bring these new technical approaches together, demonstrate selected advances with synthetic example data, and show how they conceptually contribute to life course research. This article demonstrates that in less than a decade, the field has made much progress toward fulfilling the prediction that Andrew Abbott made in 2000, that "anybody who believes that pattern search techniques are not going to be basic to social sciences over the next 25 years is going to be very much surprised" (p. 75).

Visualization is a potentially powerful tool for exploration and complexity reduction of categorical sequence data. This article discusses currently available sequence visualization against established criteria for graphical excellence in the visual display of quantitative information. Existing sequence graphs fall into two groups: They either represent categorical sequences or summarize them. The authors propose relative frequency sequence plots as an informative way of graphing sequence data and as a bridge between data representation graphs and data summarization graphs. The efficacy of the proposed plot is assessed by the R 2 and the F statistics. The applicability of the proposed graphs is demonstrated using data from the German Life History Study on women's family formation.
Since the 1970s people have retired increasingly early across advanced societies. Parallel to this trend, numerous institutional early retirement pathways evolved, such as bridge unemployment and pre-retirement schemes. This article compares retirement in Britain and Germany to show how individuals progress through these institutional retirement pathways. The analysis uses longitudinal data and recent innovations in sequence analysis to capture the sequential nature of retirement as a series of transitions over time. As expected, prominent institutional retirement pathways are mirrored in individual retirement trajectories. Beyond these expected patterns, there are pronounced regularities in individual retirement trajectories outside of explicit institutional pathways. The ‘institution of the family’ is an additional powerful force in structuring women's retirement. Access to advantageous institutional retirement pathways is stratified by gender, education, income, and health. The article concludes that specific population groups, particularly women, are systematically excluded from protective institutional early retirement pathways in Britain and Germany.
We analyze the impact of economic globalization and industry growth on the complexity of early work careers in Germany. We conceptualize complexity as the absolute number of employer changes, the regularity in the order of job changes, and the variability of the durations spent in different employment states. Results from empirical analyses based on the German Life History Study (N = 5453) show only a small increase in the complexity of work careers over the last decades, but there was a shift in the prevalence of different career patterns. This suggests that effects of globalization might be counteracted or modified by other social changes that affected work careers in Germany during the last 60 years. In particular, we consider the possible impact of educational expansion, labor market restructuring, and women's increased employment. We find no evidence that industry-specific economic globalization impacts the complexity of work careers, but we find a U-shaped relationship between industry growth and career complexity. Careers are slightly more complex in industries with high or low industry growth. We conclude that, while there has been a shift in career patterns over time, the impact of globalization on career stability is possibly overestimated.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
