Résumé

This paper is concerned with the summarization of a set of categorical sequences. More specifically, the problem studied is the determination of the smallest possible number of representative sequences that ensure a given coverage of the whole set, i.e. that have together a given percentage of sequences in their neighbourhood. The proposed heuristic for extracting the representative subset requires as main arguments a pairwise distance matrix, a representativeness criterion and a distance threshold under which two sequences are considered as redundant or, identically, in the neighborhood of each other. It first builds a list of candidates using a representativeness score and then eliminates redundancy. We propose also a visualization tool for rendering the results and quality measures for evaluating them. The proposed tools have been implemented in our TraMineR R package for mining and visualizing sequence data and we demonstrate their efficiency on a real world example from social sciences. The methods are nonetheless by no way limited to social science data and should prove useful in many other domains.

Résumé

In this paper we argue that in order to test competing hypotheses on the emergence of social mortality differentials, one has to adopt a long-term perspective. Studying social inequality in mortality in Geneva from 1625 to 2005, we use historical mortality data published by different authors and contemporary data drawn from an ongoing research project. The comparison over four centuries gives evidence to both the constancy and convergence hypotheses. Mortality is systematically lower-than-average among elites on the one hand, but on the other hand the difference between the top and the bottom of the social ladder is decreasing over time.

Résumé

Various papers published in Switzerland and elsewhere in Europe have highlighted an improvement in the living conditions of new cohorts reaching retirement age. This paper examines whether this general trend to old age democratization applies also to elderly immigrants. It reviews some dimensions of the older immigrant population situation in Switzerland. It explores mainly their socio-economic and health situation. The article also examines their access to social security and to social services for elderly people. It reports selected findings from two original surveys carried in Switzerland in the 1990s (Pre-Retired Immigrants study, PRI) and the 2000s (Minority Elderly Care study, MEC) on older Italian, Spanish and former Yugoslavians citizens who are residents in the country. The article gives also more general information about Swiss social security and social work with older populations.

Résumé

In this article, the authors define a methodological framework for analyzing the relationship between state sequences and covariates. Inspired by the principles of analysis of variance, this approach looks at how the covariates explain the discrepancy of the sequences. The authors use the pairwise dissimilarities between sequences to determine the discrepancy, which makes it possible to develop a series of statistical significance–based analysis tools. They introduce generalized simple and multifactor discrepancy-based methods to test for differences between groups, a pseudo-R2 for measuring the strength of sequence-covariate associations, a generalized Levene statistic for testing differences in the within-group discrepancies, as well as tools and plots for studying the evolution of the differences along the time frame and a regression tree method for discovering the most significant discriminant covariates and their interactions. In addition, the authors extend all methods to account for case weights. The scope of the proposed methodological framework is illustrated using a real-world sequence data set.

Résumé

Does culture shape the demand for social insurance against risks to health and work? We study this issue across language groups in Switzerland where a language border sharply separates social groups at identical actual levels of publicly provided social insurance. We find substantially stronger support for expansions of social insurance among residents of French, Italian or Romansh‐speaking language border municipalities compared with their German‐speaking neighbours in adjacent municipalities. Informal insurance does not vary enough to explain stark differences in social insurance but differences in ideology and segmented media markets potentially contribute to the discrepancy in demand for social insurance.

Résumé

A sociological explanation of conjugal conflict was often stressed but seldom empirically tested. Based on a two-wave longitudinal dataset of 1534 women in heterosexual relationships, we use structural equation modeling (SEM) to measure the impact of the division of household labor, individualism and conjugal closure on the likelihood of conjugal conflicts. Results indicate that conjugal individualism has a major impact, division of household labor a minor impact, and conjugal closure no impact, on conjugal conflict. Results are discussed in the light of current sociological debates on partnerships.
