| Abstract: This paper investigates the reproductive life course of native and immigrant women in 19th century Antwerp and Geneva, two contexts characterized by rapid population growth, urbanization and immigration. Using data from the COR*-sample of Antwerp and from a family reconstitution of Geneva, we analyze individual family life courses in a sequential data perspective. We conceptualize the reproductive life course as a sequence of 4 states: the phase between the entry into reproductive age and marriage (1), the interval between marriage and first birth (2), the period of childbearing (3) and the phase of completed family size (4). The analysis shows an opposition between local immigrants (characterized by long childbearing periods) and long-distance immigrants (longer periods of completed family size) in Antwerp. In Geneva, natives married at a much younger age than immigrants, which explains why their life course was characterized by a longer period of completed family size. |

| Abstract: Optimal matching (OM) is a method that assesses sequence similarity. It was originally developed to study protein and DNA sequences and was later transferred to the social sciences where it was applied accordingly. However, there is an ongoing debate on the adequacy of its use in the social sciences, as a superficial transfer might not respond to the significant differences between typical sequences in biological and social settings. In this paper, I elaborate on these differences and introduce a distinction between two sequence types—namely, common ancestors and unfolding processes. While the first sequence type is typically found in biological settings (e.g., DNA sequences), the latter applies to most sequences studied in the social sciences (e.g., careers). Based on this distinction, I present a new way of coding sequences as an extension to conventional OM analyses and demonstrate its usefulness in simulated and empirical examples. The paper concludes with a discussion of this new approach and its integration into previous extensions of OM. |

| Abstract: Do certain patterns of actors’ behavior reinforce or undermine democracy? Are different patterns of bargaining associated with different regime types? Earlier work (Casper and Taylor 1996) showed that countries where actors bargained intensely to install democracy after a period of authoritarianism were more likely to have negotiated a wide range of details concerning the new rules of the game. To the extent that this pattern of bargaining and cooperation continued, the new democracies were more likely to consolidate. In this paper, we consider the effect of actors’ behavior in a broader set of circumstances - national crises - to see whether different patterns of cooperation or conflict are associated with different regime types. We used both qualitative and quantitative analysis to answer our research questions. Qualitative analysis entailed capturing actors’ behavior across forty-two crises in twelve countries from 1950-1999. We used three crises that occurred in Italy as the basis on which to derive hypotheses for the crises in our remaining eleven countries. For the quantitative analysis, we coded actors’ behavior across the crises using the Intranational Political Interactions (IPI) codes. We then applied sequence analysis to cluster the crises based on the actors’ levels of cooperation and conflict. Over two-thirds of our sample cluster into two distinct groups that differ in the level and duration of conflict as well as regime type. Furthermore, three factors are associated with these patterns of clustering: need, group support, and type of crisis. In future work we plan to extend our investigation of the actors’ behavior to explain regime stability. |

| Abstract: We study the scheduling of work by using optimal matching analysis. We show that optimal matching can be adapted to the number of periodicities and theoretical concerns of the topic by adjusting its costs and parameters. Optimal matching is applied at two stages to define workdays and workweeks at the first and second stage respectively. There were five types of workdays and seven types of workweeks in the UK between 2000 and 2001. Standard workdays represented just over a half of workdays and standard workweeks constituted one in four workweeks. There were three types of part-time workweeks. |

| Abstract: Sequence analysis has been an increasingly popular tool to find patterns in sociological sequences. Sequence analysis compares sequences individually on similarity after which similar sequences are clustered into distinct groups. Analysing how and why certain groups are different from other groups yields important insights. This paper proposes more useful method to calculate sociologically valid similarity values between sequences. It is shown that the proposed method does not only yield sociologically expected results, it also outperforms existing algorithms with regard to the valuation of order and the support for time-dependent substitution matrices. Moreover, it supports both single-channel and multi-channel sequences, as well as sequences of unequal length. Finally, tests on existing data-sets show that the new method produces sociologically expected results for real-life data, and that the algorithm is confident in doing so. |

| Abstract: Characterization of lifetime behavioral changes is essential for understanding aging and aging-related diseases. However, such studies are scarce partly due to the lack of efficient tools. Here we describe and provide proof of concept for a stereo vision system that classifies and sequentially records at an extremely fine scale six different behaviors (resting, micro-movement, walking, flying, feeding and drinking) and the within-cage (3D)location of individual tephritid fruit flies by time-of-day throughout their lives. Using flies fed on two different diets, full sugar-yeast and sugar-only diets, we report for the first time their behavioral changes throughout their lives at a high resolution.We have found that the daily activity peaks at the age of 15–20 days and then gradually declines with age for flies on both diets. However, the overall daily activity is higher for flies on sugar-only diet than those on the full diet. Flies on sugar-only diet show a stronger diurnal localization pattern with higher preference to staying on the top of the cage during the period of light-off when compared to flies on the full diet. Clustering analyses of age-specific behavior patterns reveal three distinct young, middle-aged and old clusters for flies on each of the two diets. The middle-aged groups for flies on sugar-only diet consist of much younger age groups when compared to flies on full diet. This technology provides research opportunities for using a behavioral informatics approach for understanding different ways in which behavior, movement, and aging in model organisms are mutually affecting. |

| Abstract: This study examines the impact of demographic and socio-economic variables on the variability of family-life trajectories during young adulthood. We define life-courses as sequences on a monthly time scale and we apply optimal matching (OM) to compute dissimilarities between individuals. We propose a generalization of analysis of variance (ANOVA) to evaluate the link between non-metric measures (sequence dissimilarities) with categorical variables. We conduct hypothesis test using a permutation approach. Data come from the first and third wave of The National Longitudinal Study of Adolescent Health (Add Health). The sample is restricted to women from age 18 to 24. |

| Abstract: Une perspective interactionniste sur les carrières sociopolitiques à base de données de questionnaire doit prendre en compte la diversité des parcours individuels, dans une pluralité de sphères de vie, et intégrer la complexité des parcours en termes d'occupation de statuts et de rôles et de réaménagements identitaires. Afin de traiter le temps social dans toute sa complexité, c'est-à-dire à la fois la nature des expériences individuelles, leur durée et leur ordre, nous recourons à l'analyse séquentielle (AS), en particulier à l'optimal matching. Plusieurs logiciels sont testés, le module TraMineR sous R s'avérant particulièrement adapté, moyennant des ajustements aux données multiséquentielles. La comparaison pragmatique de séquences standardisées débouche sur une classification des biographies, qui sont ensuite décrites au moyen de graphes monocarrières et multicarrières, de répertoires de sous-séquences typiques et de croisements avec les données longitudinales et extra-longitudinales. Elles peuvent ensuite être lus dans le contexte générationnel, organisationnel et historique. Au final, l'importation en sociologie politique de l'AS répond à certaines des critiques qui ont été adressées à celle-ci et incite à de nouveaux développements statistiques et informatiques. |

| Abstract: This article examines pathways to adulthood among cohorts born in the second half of the nineteenth century. Although largely overlooked by previous studies, theory suggests that life courses of young adults born during this period were already influenced by a process of standardization, in the sense that they became more similar over time. Using data from a Dutch registry-based sample, we examine household trajectories, that is, sequences of living arrangements of young adults aged 15-40. Our study shows that for successive cohorts household trajectories became more similar. We identified six types of trajectories: early death, life-cycle service, early family formation, late family formation, spinster- and bachelorhood, and childless and with partner. Over time, early family formation gradually became the 'standard' trajectory to adulthood. However, late family formation and spinster- and bachelorhood, common pathways within the pre-industrial West-European Marriage Pattern, remained widespread among late nineteenth century born cohorts. Laboring class youths, farmers' daughters, young people of mixed religious background, and urban-born youngsters were the nineteenth century forerunners of a 'standard' pathway to adulthood. |

| Abstract: Goldthorpe's conception of mobility into service class relies strongly on biographical explanations. Hence, it is surprising that empirically biographical trajectories are merely approached by methodological proxies. Employing a sequence analysis of the work histories of 13,119 members of the NCDS 1958 cohort we examine different routes into service class. It appears that there are two important roads leading to the service class: one direct and short, the other tortuous and long. Surprisingly, these two routes fork not along the boundaries of the fractions of the service class, but along gender lines. Women move later and through feeder occupations to service class positions, whereas men attain these positions immediately subsequent to the educational phase. In conclusion, we distinguish a feeder phase during which men win their spurs on the route to management from a female feeder-logic of "retarded realisation" of educational credentials on the road to professionalism. |

| Abstract: Drawing upon the trajectory-based (holistic) approach, this article compares early family trajectories observed during the socialist period with those after the transition to a market economy in the Czech Republic. It aims (1) to provide an empirical analysis of change in the heterogeneity of early family trajectories between the ages of 18 and 35 and (2) to identify their distinct patterns. To do this an entropy index and optimal matching analysis is applied. The paper uses data from the ISSP 2002, which included questions on partnership and family history in the Czech Republic. The findings show that the process of de-standardisation is quite complex and non-uniform. Cohorts born from the 1970s on experience more diverse early family trajectories than older cohorts, mainly due to increasing unmarried cohabitation. However, in the cohort born in the 1980s we can observe a reversal trend of declining diversity of family statuses in the subjects' early twenties due to the postponement of family related transitions. Even among older birth cohorts, who experienced their family starts under the socialist regime, it is possible to find a certain plurality of family starts, differentiated by the level of education. |

| Abstract: Categorical time series, covering comparable time spans, are often quite different in a number of aspects: the number of distinct states, the number of transitions and the distribution of durations over states. Each of these aspects contributes to an aggregate property of such series that we call "complexity". Amongst sociologists and demographers, complexity is believed to systematically differ between groups as a result of social structure or social change. Such groups differ in e.g. age, gender or status. We propose quantifications of complexity, based upon the number of distinct subsequences in combination with, in case of associated durations, the variance of these durations. A simple algorithm to compute these coefficients is provided and some of the statistical properties of the coefficients are investigated in an application to family formation histories of young American females. |

| Abstract: Applications of optimal matching analysis in the social sciences are typically based on sequences of specific social statuses that model the residential, family, or occupational trajectories of individuals. Despite the broadly recognized interdependence of these statuses, few attempts have been made to systematize the ways in which optimal matching analysis should be applied multidimensionally—that is, in an approach that takes into account multiple trajectories simultaneously. Based on methods pioneered in the field of bioinformatics, this paper proposes a method of multichannel sequence analysis (MCSA) that simultaneously extends the usual optimal matching analysis (OMA) to multiple life spheres. Using data from the Swiss household panel (SHP), we examine the types of trajectories obtained using MCSA. We also consider a random data set and find that MCSA offers an alternative to the sole use of ex-post sum of distance matrices by locally aligning distinct life trajectories simultaneously. Moreover, MCSA reduces the complexity of the typologies it allows to produce, without making them less informative. It is more robust to noise in the data, and it provides more reliable alignments than two independent OMA. |

| Abstract: Cette analyse met en évidence l’évolution des trajectoires de formation suivies depuis le premier quart du XXe siècle. S’appuyant sur une enquête biographique rétrospective auprès d’un échantillon représentatif de 3500 personnes résidant en Suisse, cette étude rend compte des itinéraires, à travers les phases composant le curriculum d’une personne en formation. La perspective classique, articulée sur l’indication du diplôme ne reflète pas les caractéristiques des parcours effectivement suivis. Le diplôme peut être l’aboutissement d’un itinéraire sinueux, oscillant entre plusieurs filières, redoublant ou s’interrompant. Il peut aussi résulter de la reconnaissance de compétences acquises lors d’expériences professionnelles ou s’ajouter à un diplôme inférieur. Il peut enfin ne jamais être obtenu, malgré plusieurs années de formation. Il est impossible de déduire ces scénarios de la seule indication du diplôme le plus élevé. La tendance historique à l’allongement de la formation, commentée dans la littérature scientifique (Prost 1986) est analysée ici sous l’angle de la forme des trajectoires typiques et de leurs liens à l’origine sociale. |

| Abstract: User studies with geographic and other interactive information visualizations have the potential to produce datasets that contain sequences of user behaviors. One barrier to exploiting the information that these behavioral sequences contain is the difficulty of finding appropriate analytical methods for probing such datasets. This paper outlines some of the potential uses, advantages and disadvantages of two types of methodologies for analyzing sequential data: sequence alignment and sequence mining. Sequence alignment is essentially concerned with identifying regions of similarity between sequences and then grouping sequences according to a similarity score. This score is based upon the size and number of regions within the sequences that are identical. Sequence mining, on the other hand, while also concerned with finding interesting and relevant statistical patterns in sequences, focuses less on identifying groups of sequences and more on providing a wide range of sequence metrics that can be used to compare different sequences. Sequence alignment and sequence mining offer some advantages over simple visual analysis of sequences because they provide comparable quantitative measures of sequence similarity of geovisualization user behavioral patterns. A remaining challenge lies in determining which method is best used in a particular context. |

| Lesnard, L. (2009), "Cost Setting in Optimal Matching to Uncover Contemporaneous Socio-Temporal Patterns". Notes & Documents, 2009-03. SciencesPo. Observatoire sociologique du changement, Paris, 2009. |
| Abstract: This article addresses the question of the effects of cost setting on the kind of temporal patterns Optimal Matching (OM) can uncover when applied to social science data. It is argued that the balance between indel (insertion and deletion) and substitution costs determines what kind of socio-temporal pattern can be brought to light. Insertion and deletion operations favor identically coded states irrespective of their locations whereas substitutions ones focus on contemporaneous similarities. The lower the ratio of substitution to indel costs, the closer OM is to the Hamming distance where only substitutions are used. The higher this ratio, the closer OM is to the Levenshtein II distance, which amounts to finding the longest common subsequence. When the timing of sequences is crucial, substitutions should be favored over indels and their costs should be carefully fixed. Ideally, substitution costs should vary with time to better take into account the timing of the sequences studied. As indels warp time, hence the timing of sequences, it is suggested to use only substitution operations with time-dependent costs inversely proportional to transition frequencies whenever the timing of sequences is central. This OM variant, coined Dynamic Hamming Matching, is applied to the question of the scheduling of paid work where timing is critical (1985 and 1999 French time-use surveys, N = 7908) along with three classical OM variants (Hamming and Levenshtein I and II). As expected, the two Hamming dissimilarity measures fare better to identify patterns of workday schedules, as measured by entropy, than the two Levenshtein ones. |

| Abstract: Analyzing school-to-work transitions is an important challenge for the specialists of the labor-market. The aim of this paper is to study the insertion of graduates and to identify the main career-paths typologies. We introduce a new methodology for clustering career-paths by combining statistical estimation of non-homogeneous Markov chains with self-organizing maps. The proposed methodology is tested on real-life data issued from the survey ``Generation 98'' elaborated by CEREQ, France (http://www.cereq.fr/) |

| Abstract: This paper is devoted to the analysis of career paths and employability. The state-of-the-art on this topic is rather poor in methodologies. Some authors propose distances well adapted to the data, but are limiting their analysis to hierarchical clustering. Other authors apply sophisticated methods, but only after paying the price of transforming the categorical data into continuous, via a factorial analysis. The latter approach has an important drawback since it makes a linear assumption on the data. We propose a new methodology, inspired from biology and adapted to career paths, combining optimal matching and self-organizing maps. A complete study on real-life data will illustrate our proposal. |

| Abstract: Dans un précédent travail, Winkler-Dworak et Toulemon (2007) ont comparé les modalités du passage à l'âge adulte à partir de modèles de durée, décrivant les évolutions des mises en couple et des premières naissances et leurs variations selon la situation face à la fin des études et du premier emploi. Les contraintes auxquelles sont soumis les femmes et les hommes en termes de mise ne couple et de naissance du premier enfant ont eu tendance à se rapprocher, entre les générations nées au début des années 1940 et celles nées au début des années 1960. Dans le cadre d'une approche globale de la transition vers l'âge adulte (Galland 2000, Galland 2007, Robette 2008), cet article cherche à analyser les transitions vers l'âge adulte en les décrivant de manière globale, plutôt qu'en considérant a priori que certains évènements influent sur la survenue d'autres évènements. Après une rapide présentation des données et des méthodes d'optimal matching permettant de calculer des distances entre des séquences d'états, nous décrirons la diversité des situations des jeunes adultes. Puis nous décrirons la complexité des séquences à l'aide des mesures de l'entropie et de la turbulence, en précisant la différence entre ces deux indicateurs. Enfin, nous reviendrons sur la question de l'évolution de la différence entre femmes et hommes pour comparer nos résultats avec ceux obtenus par des méthodes radicalement différentes |

| Abstract: We present results from a study examining how visual selection feedback and map layout impact interaction when expressing spatial queries on paper maps using handheld devices. A sequence analysis of gaze patterns indicates that efficient queries involved a progression of visual attention from the paper map to the handheld device for a city street map with a grid layout, and a more balanced split of attention for a landmark-heavy city tourist map. Selection feedback emphasizing the most prominent aspects of a map's visual layout yielded a large cluster of trials employing the more efficient approach for each map: a dynamic iconic list-view did this for the tourist map, versus a magic-lens map-view for the street map. Map layout correspondingly influenced the interaction technique chosen, such that continuous path selections were more frequent for the street map, while regional and discrete selections were more frequent for the tourist map. |

| Abstract: Extant ethnographic studies suggest that the nuclear family has been the predominant living arrangement in Cambodia, and the country's rapid socioeconomic transformation since the early 1990s may have accentuated that dominance. To examine these claims, we analyse here household structure in Cambodia between 1998 and 2006, based on data from the 1998 Census, two nationally-representative surveys (2000 and 2005), and a continuing demographic surveillance system (from 2000 on). Our analysis confirms the large prevalence of nuclear families, but not an unequivocal trend toward their increasing prevalence. First, nuclear families are less prevalent in urban than in rural areas, and nationwide, they appear to have receded slightly between 2000 and 2005. We find that increases in the prevalence of extended households correspond to periods of faster economic growth, and interpret these contrasted trends as signs of tensions during this transitional period in Cambodia. While the nuclear family may still be the cultural norm, a high degree of pragmatism is also evident in the acceptance of other living arrangements, albeit temporary, as required by economic opportunities and housing shortage in urban areas. |
