| Abstract: We illustrate a novel data-driven way of visualizing paths of labor market transitions. The proposed technique is used in many fields of science when analyzing transitions longitudinally. The statistical method applied in this study is based on sequence analysis (SA) used to identify similar and dissimilar individual transition patterns over longitudinal measurements. We briefly introduce the statistical basis of SA and discuss its use in the dynamic microsimulation context. We also report our results from the Finnish ELSI model to illustrate labor market transitions near retirement. SA is available in many popular statistical software packages such as R and Stata. The programming code for SA and data simulations are also given. Our conclusion is that SA is a useful tool also in a microsimulation context, in visualizing and validating simulated model transitions when statistically more sophisticated mixture modeling are not applicable. |

| Abstract: Price inflation has outbalanced the income of residents and buyers in major post-industrial city-regions, and real estate has become an important driver of these inequalities. In a context of a resilient inflation of home values during the last two decades in the greater Paris Region, it is critical to examine housing price dynamics to get a better understanding of socioeconomic segregation. This paper aims at presenting spatial analysis of the dynamics of segregation pertaining to inflation, analyzing price and sellers and buyers data. Using interpolation techniques and multivariate analysis, the paper presents a spatial analysis of property-level data from the Paris Chamber of Notaries (1996-2012) in a GIS (159,000 transactions in suburban areas, single family homes only). Multivariate analysis capture price change and local trajectories of occupational status, i.e. changes in balance between inward and outward flows of sellers and buyers. We adopt a method that fits the fragmented spatial patterns of suburbanization. To do so, we remove the spatial bias by means of a regular 1-km spatial grid, interpolating the variables within it, using a time-distance matrix. The main results are threefold. We document the spatial patterns of professionalization (a rise of executives, intermediate occupation and employees) to describe the main trends of inward mobility in property ownership in suburbs, offsetting the outward mobility of retired persons. Second, neighborhood trajectories are related the diverging patterns of appreciation, between local contexts of accumulation with a growth of residential prices, and suburbs with declining trends. The maturity of suburbanization yields a diversified structure of segregation between the social groups, that do not simply oppose executives vs. blue collar suburbs. A follow-up research agenda is finally outlined. |

| Abstract: In this study, methods, originally developed to assess life course trajectories, are explored in order to evaluate land change through the analysis of sequences of land use/cover. Annual land cover maps which describe land use/land cover change for the 1985–2017 period for a large region in Northeast Brazil were analyzed. The most frequent sequences, the entropy and the turbulence of the land trajectories, and the average time of permanence were computed. Clusters of similar sequences were determined using different dissimilarity measures. The effect of some covariates such as slope and distance from roads on land trajectories was also evaluated. The obtained results show the potential of these techniques to analyze land cover sequences since the availability of multidate land cover data with both, high temporal and thematic resolutions, is continuously increasing and poses significant challenges to data analysis. |

| Abstract: Most existing activity-based travel demand models are implemented in a tour-based microsimulation framework. Due to the significant computational and data storage benefits, the demand microsimulation allows a greater amount of flexibility in terms of demographic market segmentation, temporal scale, and spatial resolution, and thus the models can represent a wider range of travel behavior aspects associated with various policies and scenarios. This dissertation proposes three innovative methodologies, one for each of the three key dimensions, to fulfill the greater level of details toward a more mature state of activity-based travel demand model. |

| Abstract: This article analyses whether the trend of extending working lives has coincided with a destabilisation of late careers in Finland. On one hand, reforms that eliminate alternative exit pathways typically have been aimed at simplifying the transition from work to retirement. On the other hand, the need to work longer might entail a risk of increasing transitions between work and non-employment, as well as between jobs. Destabilisation is defined as the process of increasing complexity within individual life-course patterns over time. Using register-based Finnish Linked Employer-Employee Data, complexity within individual sequences of annual labour-market statuses between ages 51 and 65 is calculated for the Finnish population born between 1937 and 1948 (N?=?238,099). Distinction is made between sequences that only include transitions between employment and non-employment and sequences that include transitions between different jobs as well. Results show that the average late-career complexity has decreased when only transitions between work, unemployment, and pension types are considered, especially among women and the higher-educated. Less change is observed among the lower-educated. When transitions between jobs are included, the results show a slight late-career destabilisation among men and lower-educated, but a decrease in complexity among women and higher-educated. The findings suggest that late-career complexity was increasingly determined by transitions between jobs rather than between spells of employment and non-employment. However, lower-educated older workers continued to be at greater risk of early exit, while at the same time experiencing destabilising employment careers. |

| Abstract: In Belgium, lone parent families represent almost one fourth of the households with children, aside from the existence of regional differences in the phenomenon's prevalence. Zooming in on Flanders, the poverty risk for this type of family is significantly higher compared to couple-with-children households and the general population; thus, labour market participation represents a crucial resource for individuals heading such households to cope with the economic needs of the family and to avoid long-lasting poverty or to rely extensively on social assistance. We use data from the Crossroads Bank of Social Security (CBSS Datawarehouse) to study Flemish lone mothers' patterns of labour market participation and test the association between employment trajectories after lone parenthood and both individual and household characteristics. Flanders represents an interesting case because of (i) the relatively high diffusion of lone motherhood, (ii) the presence of welfare measures supporting a number of different types of recipients (even to different extents and not necessarily so generous to keep them out of poverty), and (iii) the availability of longitudinal data to observe lone mothers' employment trajectories over time. We find that differences exist among lone mothers, who thus experience different risk of social exclusion driven by family and labour market arrangements set up to resolve the potentially contradictory trade-off between the needs for care and for income. The age at which mothers have children is crucial in understanding their future exclusion from the labour market: selection into early lone motherhood is associated with lower employment opportunities. Furthermore, it is the number of children below 17 in the household rather than the presence of very small children that defines a lower probability of having a strong labour market attachment through full-time jobs, and that increases the likelihood of being unemployed/inactive and receiving welfare benefits. |

| Abstract: A destandardization of labor-force patterns revolving around retirement has been observed in recent literature. It is unclear, however, to which degree and of which kind. This study looked at sequences rather than individual statuses or transitions and argued that differentiating older Americans' retirement sequences by type, order, and timing and considering gender, class, and race differences yields a less destandardized picture. |

| Haenssgen, M.J. & Ariana, P. (2017), "Healthcare access: A sequence-sensitive approach", SSM - Population Health. Vol. 3, pp. 37-47. |
| Abstract: It is widely accepted that healthcare-seeking behaviour is neither limited to nor terminated by access to one single healthcare provider. Yet the sequential conceptualisation of healthcare-seeking processes has not diffused into quantitative research, which continues to analyse healthcare access as a "one-off" event. The ensuing lack of understanding healthcare behaviour is problematic in light of the immense burden of premature death especially in low- and middle-income countries. This paper presents an alternative approach. Based on a novel survey instrument, we analyse original survey data from rural India and China that contain 119 unique healthcare pathways among 637 respondents. We offer three applications of how such sequential data can be analysed to enhance our understanding of people's health behaviour. First, descriptive analysis of sequential data enables more a comprehensive representation of people's health behaviours, for example the time spent in various healthcare activities, common healthcare pathways across different groups, or shifts in healthcare provider access during a typical illness. Second, by analysing the effect of mobile technology on healthcare-seeking process characteristics, we demonstrate that conventional, sequence-insensitive indicators are potentially inconsistent and misleading approximations when compared to a more precise, sequence-sensitive measure. Third, we describe how sequential data enable transparent and flexible evaluations of people's healthcare behaviour. The example of a sequence-insensitive evaluation suggests that household wealth has no statistical link to an illustrative "ideal" form of public healthcare utilisation. In contrast, sequence-sensitive evaluations demonstrate that household wealth is associated with an increased likelihood of bypassing referral processes and approaching unregulated and costly informal and private practitioners before accessing a public clinic. Sequential data therefore do not only reveal otherwise neglected locational idiosyncrasies, but they also yield deeper insights into the drivers of people's health behaviours compared to a conventional approach to "access to healthcare." |

| Abstract: Scholars have long debated the relative merits of site-based, subsidized housing owned and operated by a public entity or by the private sector. This is the first study to classify long-term residential trajectories of nationally representative low-income households in the United States by their initial assisted housing status. We employ a matched sequence analysis of neighborhood poverty and racial trajectories of low-income households in the Panel Study of Income Dynamics who formed during 1988–1992. Among households carefully matched by their demographic and economic attributes, we find that those first forming households in public housing spend much longer durations over the subsequent 20 years in poorer, minority dominant neighborhoods than similar households first forming in market-rate housing do. In contrast, forming a household in private site-based subsidized housing is associated with superior neighborhood socioeconomic (but not desegregated racial composition) trajectories compared with starting in market-rate housing. Implications for housing policy are discussed. |

| Abstract: Neighborhood poverty experienced over time by low-income households is a topic of increasing interest and public policy importance. We employ sequence analysis of neighborhood poverty rates to identify distinct patterns among the 18- to 22-year longitudinal residential trajectories of 389 low-income households in the United States who formed households during 1988–1992, as represented in the Panel Study of Income Dynamics. Our most striking finding is the important role of poverty in their first neighborhood to the probability that low-income households ultimately reside in neighborhoods with higher poverty rates. Contrary to conventional wisdom, there are a wide variety of neighborhood poverty trajectories that low-income American households experience. However, those with felicitous neighborhood trajectories were almost entirely White households. The majority of Blacks formed households in high-poverty neighborhoods and were unlikely to live in any other sort of neighborhood for the next two decades when they are typically raising children. In addition, both in-place neighborhood changes and residential mobility have likely led to this racial variation in low-income neighborhood trajectories. We contribute to the evidence base about the role of place in perpetuating socioeconomic and racial inequalities. |

| Abstract: The gap between wealthy and disadvantaged neighbourhoods seems to be increasing in many contemporary Western cities. Most studies of neighbourhood change focus on specific case-studies of neighbourhood downgrading or gentrification. Studies investigating socio-spatial polarisation in larger urban areas often compare neighbourhoods at two points in time, neglecting the underlying dynamic character of neighbourhoods. In the current literature, the question if neighbourhoods with similar characteristics experience similar changes over time remains unanswered. As a result, it is unclear why some neighbourhoods appear to be more prone to change than others. In this paper, we propose a dual approach for analysing neighbourhood change. We argue that researchers should both adopt a long-term perspective (20–40 years), because significant changes are only visible after longer periods of time, and focus on more detailed neighbourhood trajectories to understand how neighbourhood change is interrelated with context. Focussing on Dutch neighbourhoods over the period 1971–2013, we analyse the role of physical characteristics on low-income neighbourhood trajectories using an innovative visualisation technique. A tree-structured discrepancy analysis allows for the visualisation of complete neighbourhood pathways, enabling the analysis of complex, contextualised patterns of change. We find that the original quality of neighbourhoods and dwellings seems to be an important predictor for future neighbourhood trajectories, indicating a high level of path-dependency. |

| Abstract: Visual distraction among cyclists interacting with their mobile phones is a growing concern. Yet, very little research has actually investigated how cyclists apply visual strategies and adapt task execution depending on the traffic situation. The aim of this study is to investigate visual behaviour of cyclists when conducting self-paced (initiated by the cyclist) vs. system-paced (initiated by somebody else) smartphone tasks in traffic. Twenty-two cyclists completed a track in real traffic while listening to music, receiving and making calls, receiving and sending text messages, and searching for information on the internet. The route and the types of tasks were controlled, but the cyclists could choose rather freely when and where along the route to carry out the tasks, thus providing semi-naturalistic data on compensatory behaviour. The results show that the baseline and music conditions were similar in terms of visual behaviour. When interacting with the phone, it was found that glances towards the phone mostly came at the expense of glances towards traffic irrelevant gaze targets and also led to shortened glance durations to traffic relevant gaze targets, while maintaining the number of glances. This indicates that visual “spare capacity” is used for the execution of the telephone tasks. The task type influenced the overall task duration and the overall glance intensity towards the phone, but not the mean nor maximum duration of individual glances. Task pacing was the factor that influenced visual behaviour the most, with longer mean and maximum glance durations for self-paced tasks. In conclusion, the cyclists used visual strategies to integrate the handling of mobile phones into their cycling behaviour. Glances directed towards the phone did not lead to traffic relevant gaze targets being missed. In system-paced scenarios, the cyclists checked the traffic more frequently and intensively than in self-paced tasks. This leads to the assumption that cyclists prepare for self-initiated tasks by for example choosing a suitable location. Future research should investigate whether these strategies also exists amongst drivers and other road user groups. |

| Abstract: Digital tracking technologies have considerably increased the amount and quality of animal trajectories, enabling the study of habitat use and habitat selection at a fine spatial and temporal scale. However, current approaches do not yet explicitly account for a key aspect of habitat use, namely the sequential variation in the use of different habitat features. To overcome this limitation, we propose a tree-based approach that makes use of sequence analysis methods, derived from molecular biology, to explore and identify ecologically relevant sequential patterns in habitat use by animals. We applied this approach to ecological data consisting of simulated and real trajectories from a roe deer population (Capreolus capreolus), expressed as ordered sequences of habitat use. We show that our approach effectively captured spatio-temporal patterns of sequential habitat use by roe deer. In our case study, individual sequences were clustered according to the sequential use of the elevation gradient (first order) and of open/closed habitats (second order). We provided evidence for several behavioural processes, such as migration and daily alternating habitat use. Some unexpected patterns, such as homogeneous sequences of use of open habitat, could also be identified. Our findings advocate the importance of dealing with the sequential nature of movement data. Approaches based on sequence analysis methods are particularly useful and effective since they allow exploring temporal patterns of habitat use in a synthetic and visually captive manner. The proposed approach represents a useful and effective way to classify individual movement behaviour across populations and species. Ultimately, this method can be applied to explore the temporal scale of ecological processes based on movement. |

| Abstract: Background: Previous research has concentrated on the quantum and timing of partnership statuses during the transition to adulthood, but it has however remained unclear how partnership trajectories unfold and how trajectories interdepend. It is furthermore unknown how individual characteristics and regional living conditions relate to the type of partnership trajectory an individual experiences. Objective: By studying longitudinal partnership trajectories in a sequence analysis, this article examines the types of partnership trajectories that are observable between the ages of 15 and 40. It furthermore asks how individual characteristics and regional living conditions relate to the sequencing, timing, and quantum of partnership transitions. It finally shows how the turbulence in partnership trajectories relates to these factors. Methods: I analyze the 1971-1973 birth cohort in the German Family Panel (pairfam). Results: Partnership trajectories split up into four patterns. Educational level, gender, and ethnic background significantly influence the probability of experiencing one of these partnership trajectories. Urban residents experience greater diversity in partnership statuses and are single for longer periods than rural residents. Twenty-six years after Germany's unification, socialization in eastern or western Germany still matters: Eastern Germans are more likely than western Germans to remain in a cohabitation until they are 40. Contribution: This article presents novel evidence on the typical partnership trajectories of a recent cohort. It shows that partnership histories are closely linked to membership in a social group and socialization in an institutional setting. Only some social groups are prone to experiencing turbulent partnership histories. |

| Humphries, J.E. (2016), "The Causes and Consequences of Self-Employment over the Life Cycle". paper. University of Chicago, Chicago, 2016. |
| Abstract: This paper uses population panel data from Sweden to investigate the causes and consequences of self-employment over the life cycle, and to evaluate how self-employment decisions can be influenced by policy. In the first part of the paper, I use machine learning methods to summarize the patterns of self-employment behavior observed in the data. I find that careers involving self-employment fit into a small number of economically distinct groups. Some self-employment spells are short, with minimal capital investment and rapid return to paid employment, while others persist and have substantial capital devoted to the business from the outset. Guided by these descriptive results, I develop and estimate a dynamic Roy model in which self-employment decisions depend on factors such as cognitive and non-cognitive skills, prior work experience, the cost of capital, and other labor market opportunities. The model integrates traditional models of dynamic career choice that feature human capital investment and models of business start-up that feature physical capital investment. I estimate the model and use it to evaluate policies designed to promote self-employment. Cognitive and non-cognitive skills, education, and prior work experience are important determinants of the types of businesses individuals start, how much capital they employ, and how long they remain in self-employment. Subsidies that incentivize self-employment are generally ineffective, both in terms of promoting long-lasting firms and in terms of improving the welfare and earnings of those induced to enter self-employment. |

| Abstract: Sur le front des métropoles américaines, une formidable recomposition s'est opérée : les marges métropolitaines sont devenues le lieu privilégié de l'intégration sociale. Le discours dominant sur les suburbs des États-Unis fait néanmoins la part belle aux << lotissements à l'américaine >> comme lieux de l'entre-soi, à l'hyper-ségrégation de périphéries opposées au centre, et à la monotonie d'espaces sans qualités. Pourtant, ces territoires sont construits, habités, pratiqués. Cet ouvrage analyse la production de la morphologie spatiale, fonctionnelle et sociale des espaces suburbains en Californie du Sud, sur les marges de la région urbaine de Los Angeles. L'offre, les acteurs de la construction et les dynamiques de ce marché sont analysés au prisme d'une double mutation : celle, d'une part, de la maturation et la diversification du modèle suburbain ; celle, plus brutale, de son modèle économique, révélé par l'ampleur de la crise des subprimes. L'évolution de ces territoires révèle les transformations d'une métropole étalée et fragmentée, où s'entremêlent logiques de la privatisation urbaine (les lotissements en copropriété, les gated communities), rouages de la finance et politiques publiques de maitrise de la croissance et de la densification. Les logiques du changement métropolitain sont multiples : la production de l'espace bâti et les trajectoires des suburbs se tissent par la combinaison des cycles d'urbanisation (suburbs matures, suburbs récentes, exurbs), des cycles économiques et des évolutions socio-démographiques. L'ouvrage dresse ainsi le portrait d'une suburbia en crise(s), fragmentée, mais aussi mixte, dynamique et en profond renouvellement, tant d'un point de vue socio-économique que des groupes et appartenances communautaires. |

| Abstract: This article analyses how Danish farm families adapted to harsh and changing conditions in the period after the great western agricultural crisis in the early 1980s. Drawing on Bourdieu's concepts of habitus and adaptation, I analyse the creation and consolidation of different class fractions amongst farm families due to different adaptation strategies. The data contain information about the population of self-employed farmers and their families who were between 30-35 years old in 1980 (n = 9,123). Using sequence analysis, I examine farm families' adaptation strategies for maintaining their agricultural production annually from 1980–2008. The result is a five-farmer typology that, together with logit regression models including background covariates, reveals how the farm families' adaptation strategies relate to educational level, financial situation, family composition and whether the farmer can receive help from a spouse or other close family members. |

Vol. 6(1), pp. 1-25. |
| Abstract: We present two types of approach to the analysis of recurrent events for discretely measured data, and show how these methods can complement each other when analysing co-residential partnership histories. Sequence analysis is a descriptive tool that gives an overall picture of the data and helps to find typical and atypical patterns in histories. Event history analysis is used to make conclusions about the effects of covariates on the timing and duration of the partnerships. As a substantive question, we studied how family background and childhood socio-emotional characteristics were related to later partnership formation and stability in a Finnish cohort born in 1959. We found that high self-control of emotions at age 8 was related to a lower risk of partnership dissolution and for women a lower probability of repartnering. Child-centred parenting practices during childhood were related to a lower risk of dissolution for women. Socially active boys were faster at forming partnerships as men. |

| Abstract: Late career is often seen as a more vulnerable life-stage in the labour market, in which workers may experience a deterioration in job quality. Using a life course perspective and longitudinal data, this article analyses the vulnerability associated with late career by focusing on four occupational dimensions: working-time, career continuity, retirement timing and income change. The research is carried out using data from Switzerland, a country where the age profile of the labour force is an increasing issue. The paper also adopts a cumulative disadvantage perspective to examine the impact of previous work and family life experiences on work life vulnerability at older age. Our data come from the Survey of Health, Ageing and Retirement in Europe (SHARELIFE). The paper uses cluster analysis, sequence analysis and ordered logistic regression. Results show that women with previous family responsibilities resulting in long-term unemployment or caring, often with health complications, are more likely to be vulnerable to deterioration in job quality in late career. This suggests that experiences in the last period of the working life may be just as gendered as earlier periods. |

Life course Centre Working Paper Series, 2015-29. ARC Center of Excellence for Chidren and Families over the Life Course, Queensland, AU, 2015. |
| Abstract: Life course perspectives suggest that later life health reflects long term social patterns over an individual's life, in particular the occurrence and timing of key roles and transitions. This has been demonstrated empirically for multiple aspects of fertility and partnership histories, including timing of births and marriage, parity, and the presence and timing of a marital disruption. Most previous studies have, however, addressed particular aspects of fertility or partnership histories singly. Until recently, most of this work has focused on cross - sectional associations between family statuses and health, or short-term changes in health associated with family transitions. Such analyses are limited in their ability to examine the lifelong histories of biological, social, and psychological development reflected in observed health differences. This study is the first to consider how a combined classification of marital and fertility histories over a long period of the life course is associated with later life general and functional health, and provides a new approach to understanding the position of the family in health inequalities. Our results suggest that family life course trajectories have lasting consequences for men's physical health which are dependent on the occurrence and timing of major life course events. In particular, early family formation, marital disruption, the timing of marital disruption, and failure to marry were detrimental for men's physical health. For women, we found few differences in physical health between the family life course trajectory groups: only women with both a disrupted marital history and a high level of fertility were in significantly worse health than those women who had experienced a normatively 'standard' family life course. |

| Abstract: This thesis shows how critical life events and life transitions impact on different dimensions of the relationship quality of men and women. Furthermore, it is examined how conjugal interactions intervene between critical life events and transitions and relationship quality. The study is based on the longitudinal Swiss survey «Social Stratification, Cohesion and Conflict in Contemporary families» which provides information of both partners of a couple in two points in time. The results show that critical life events and transitions which are related to the professional life are from great importance for the relationship quality of men and women. Conjugal interactions have additive effects on this impact. Additionally, fusional couples show higher relationship quality than couples where partners are autonomous from each other. In conclusion, if we want to understand conjugal relationships, it is important to consider external and internal factors. |

| Abstract: Relatively little is known about the pathways youth with autism spectrum disorders (ASDs) take in the transition to adulthood in terms of employment and postsecondary education (PSE). Applying life course sequence analysis to a nationally representative sample of youth with ASDs (N = 120), this study clustered various longitudinal sequences into three typical transition groups in the 6 years after high school exit: primarily focused on PSE (57.4%), continuously or increasingly disengaged (i.e., not employed nor in PSE, 29.0%), and primarily focused on employment (13.6%). All three groups experienced unique struggles in the transition to adulthood. We found variations in disproportionate transition patterns by gender, family income, functional cognitive skills, and conversational skills. Policy implications are discussed. |

| Abstract: Using EU-SILC panel data from years 2008 to 2010, this paper builds typologies of labour market sequences over the three years, using a clustering analysis algorithm. The results confirm the importance of individual characteristics (age, gender, education level) in observed labour market mobility patterns. Low-educated youth tend to be disadvantaged across the EU over the two years considered. Gender differences are mainly related to the importance of inactivity. Cross-country differences appear important in terms of medium term labour market trajectories, especially for youth. In particular, the heterogeneity across countries is the highest for low-educated youth. These differences are influenced by the labour market context, but also by the role of education system since sequences including studies are quite frequent. |

| Abstract: Time-use diary data convey information about the activities an individual was engaged in, when and for how long, and the order of these activities throughout the day. The data are usually analyzed by summarizing the time used per activity category. The aggregates are then used to determine the mean time use of a mean individual on an average day. However, this approach discards information about the duration of activities, the order in which they are undertaken, and the time of day each activity is carried out. This paper outlines an alternative approach grounded in the time-geographic theoretical framework, which takes the duration, order, and timing of activities into consideration and thus yields new knowledge. The two approaches to analyzing diary data are compared using a simple empirical example of gender differences in time use for paid work. The focus is on the effects of methodological differences rather than on the empirical outcomes. The argument is made that using an approach that takes the sequence of activities into account deepens our understanding of how people organize their daily activities in the context of a whole day at an aggregate level. |

(2014), "Sequence Patterns in the Resolution of Clinical Instabilities in Community-Acquired Pneumonia and Association with Outcomes", Journal of General Internal Medicine. Vol. 29(4), pp. 563-571. |
| Abstract: BACKGROUND: In patients hospitalized with community-acquired pneumonia (CAP), indicators of clinical instability at discharge (fever, tachycardia, tachypnea, hypotension, hypoxia, decreased oral intake and altered mental status) are associated with poor outcomes. It is not known whether the order of indicator stabilization is associated with outcomes. OBJECTIVES: To describe variation in the sequences, including whether and in what order, indicators of clinical instability resolve among patients hospitalized with CAP, and to assess associations between patterns of stabilization and patient-level outcomes. DESIGN / PARTICIPANTS / MAIN MEASURES: Chart review ascertained whether and when indicators stabilized and other data for 1,326 adult CAP patients in six U.S. academic medical centers. The sequences of indicator stabilization were characterized using sequence analysis and grouped using cluster analysis. Associations between sequence patterns and 30-day mortality, length of stay (LOS), and total costs were modeled using regression analysis. KEY RESULTS: We found 986 unique sequences of indicator stabilization. Sequence analysis identified eight clusters of sequences (patterns) derived by the order or speed in which instabilities resolved or remained at discharge and inpatient mortality. Two of the clusters (56 % of patients) were characterized by almost complete stabilization prior to discharge alive, but differing in the rank orders of four indicators and time to maximum stabilization. Five other clusters (42 % of patients) were characterized by one to three instabilities at discharge with variable orderings of indicator stabilization. In models with fast and almost complete stabilization as the referent, 30-day mortality was lowest in clusters with slow and almost complete stabilization or tachycardia or fever at discharge [OR = 0.73, 95 % CI = (0.28–1.92)], and highest in those with hypoxia with instabilities in mental status or oral intake at discharge [OR = 3.99, 95 % CI = (1.68–9.50)]. CONCLUSIONS: Sequences of clinical instability resolution exhibit great heterogeneity, yet certain sequence patterns may be associated with differences in days to maximum stabilization, mortality, LOS, and hospital costs. |

| Mahaney, R.A. (2014), "Exploring the Complexity and Structure of Acheulean Stoneknapping in Relation to Natural Language", Paleo Anthropology. Vol. 2014, pp. 586-606. |
| Abstract: The intuition that there is a homology between sequenced action during stoneknapping and syntax in language is long-standing, but rarely explicitly analyzed. If valid, this proposed homology would allow paleoanthropologists to gain a handle on the timing and context of language emergence. Here, I present the results of three pilot studies performed to explore the methods such an analysis would require, as well as the issues that such an analysis would raise. The replication of an Acheulean handaxe was videotaped, then coded. This lithic reduction was analyzed using information theory, formal grammars, and Markov models. These three analyses found: (1) in terms of information entropy, the thinning phase of handaxe manufacture is as complex as many English language utterances; (2) the lithic reduction can be represented as a Context-Free Grammar (CFG), though in reality it only has limited embedding and is largely iterative in structure; and, (3) the lithic reduction also can be simulated by ‘mindless’ Markov models. These results raise a number of issues. First, it is not clear how to define and validate comparable units in stoneknapping and language. It is also not clear that the flow of actions performed by a stoneknapper can be easily segmented into discrete units. Second, in Studies One and Two, it was found that handaxe replication could be simulated by both a CFG and a Markov model instantiating a Finite State Grammar. The types of cognitive mechanisms capable of instantiating these are significantly different, with a CFG requiring memory resources not needed by the simpler Markov processes. These pilot studies indicate that it is possible to utilize these methods in the analysis of stoneknapping, but a number of basic conceptual and methodological issues remain to be clarified |

| Abstract: Integrating insights from cultural sociology and identity theory, I explore the mental health consequences of adolescent romantic relationship inauthenticityâ€â€?incongruence between thoughts/feelings and actions within romantic contexts. Applying sequence analysis to National Longitudinal Study of Adolescent Health data, I measure relationship inauthenticity by quantifying the extent to which the ordering of events of actual romantic relationships (e.g., holding hands, saying “I love youâ€i?`½) diverges from the sequence of events within idealized relationship scripts among 5,316 adolescents. I then test its association with severe depression, suicide ideation, and suicide attempt. I find that romantic relationship inauthenticity is positively associated with the risk of all three markers of poor mental health, but only for girls. This study highlights the importance of gender and culture in determining how early romantic involvement influences psychological well-being. |

| Abstract: Comparing text strings in terms of distance functions is a common and fundamental task in many statistical text-processing applications. Thus far, string distance functionality has been somewhat scattered around R and its extension packages, leaving users with inconistent interfaces and encoding handling. The stringdist package was designed to offer a low-level interface to several popular string distance algorithms which have been re-implemented in C for this purpose. The package offers distances based on counting q-grams, edit-based distances, and some lesser known heuristic distance functions. Based on this functionality, the package also offers inexact matching equivalents of R’s native exact matching functions match and %in%. |

| Abstract: This paper investigates means to visualize and classify patterns of study of a college math learning environment. We gathered logs of learner interactions with a drill and practice learning environment in college mathematics. The environment offers a large number of exercises along with their solutions and the theory linked to each problem. Freshman students in engineering were invited to use the environment to refresh the prerequisite concepts of mathematics for their degree. Detailed logs of student usage was gathered for four months. Means to cluster and visualize sequence of activities within user sessions are shown. The results reveal highly distinct patterns of use that can be extracted from a clustering algorithm and visualized as sequence patterns. These means can prove useful to learning environments designers who need to better understand how their application software are used in practice by learners. In particular, the case studied reveals an unexpected, and substantial amount of navigation through exercises and notes without actually trying the exercises themselves. |

| Abstract: Wafer fabrication in the semiconductor industry is probably one of the most complex manufacturing processes. Maintaining high yields through the statistical process control as a sole monitoring method for quality control is obviously inefficient in such highly complicated operations. We thus present in this paper a sequence analysis method, which is one of the advanced data mining techniques, to identify and extract unique patterns from manufacturing data that can reveal and differentiate low performance processes from the normal ones. We also provide the program coding, implemented with the R language, for easy experimental repetition. |

Les données que nous utilisons sont issues de la base de données SISE qui recense de manière exhaustive les inscriptions des étudiants dans les universités francaises. En utilisant une méthode d'appariement optimal, nous construisons une typologie des parcours de ces étudiants avant et après l'introduction des frais d'inscription puis évaluons l'impact celle-ci sur la nature des parcours à l'aide d'un modèle logit multinomial non ordonné. Nous montrons que l'introduction de frais d'inscription dans cette université modifie les parcours en accentuant le phénomène de ségrégation sociale. |

| Abstract: Background: When providing advanced life support (ALS) in cardiac arrest, the patient may alternate between four clinical states: ventricular fibrillation/tachycardia (VF/VT), pulseless electrical activity (PEA), asystole, and return of spontaneous circulation (ROSC). At the end of the resuscitation efforts, either death has been declared or sustained ROSC has been obtained. The aim of this study was to describe and analyze the clinical state transitions during ALS among patients experiencing in-hospital cardiac arrest. Methods and results: The defibrillator files from 311 in-hospital cardiac arrests at the University of Chicago Hospital (IL, USA) and St. Olav University Hospital (Trondheim, Norway) were analyzed (clinicaltrials.gov: NCT00920244). The transitions between clinical states were annotated along the time axis and visualized as plots of the state prevalence according to time. The cumulative intensity of the state transitions was estimated by the Nelson-Aalen estimator for each type of state transition, and for the intensities of overall state transitions. Between 70% and 90% of patients who eventually obtained sustained ROSC had progressed to ROSC by approximately 15-20 minutes of ALS, depending on the initial rhythm. Patients behaving unstably after this time period, i.e., alternating between ROSC, VF/VT and PEA, had a high risk of ultimately being declared dead. Conclusions: We provide an overall picture of the intensities and patterns of clinical state transitions during in-hospital ALS. The majority of patients who obtained sustained ROSC obtained this state and stabilized within the first 15-20 minutes of ALS. Those who continued to behave unstably after this time point had a high risk of ultimately being declared dead. |

| Abstract: Although industrial organization is increasingly trending towards ecosystem competition, little is known about the processes of ecosystem emergence. We apply institutional theory, event colligation and optimal matching to extract and compare sequences of four types of activities---re-source, technological, institutional and contextual---in six successful ecosystem creation cases: Amazon, eBay, Facebook, Google, Salesforce, and Wikipedia. We show that although the emergence process of each ecosystem is unique, there are three common phases of emergence ? Initiation, Momentum, and Optimization. Path dependency and equifinality are then demonstrated through decreasing cross-subject similarities for each successive phase. |

| Abstract: We use electoral participation data coded from signature lists to show that patterns of voter turnout, be they related to average participation, versatility or precise moments of voting, are strongly related to what we call `electorate households', i.e. groups of voters registered in the same polling station and living together. Each household tends to be homogeneous, at levels much higher than chance would explain, so that modelling individual participation without taking this household effect into account ignores much of what actually happens. The status in the household also plays an important role among individual factors of voter participation. Not only do people who live together often participate together, but the precise shape of their relationships influences their behaviour. |

| Abstract: Daily mobility and transport demand have always been described and forecast through the concept of trip, de ned since early transportation studies [1] as the movement linking two activities. Over the last thirty years a growing number of studies have tried to change the perspective in order to better grasp daily mobility. Among these approaches one deserve a particular attention: the so called "activity based" approach. This approach, closely linked to Swedish time-geography, aims to comprehend daily mobility not as a juxtaposition of trips but as a chain of interdependent trips and activities |

| Abstract: Objective: To investigate the evolution of delirium of nursing home (NH) residents and their possible predictors. Design: Post-hoc analysis of a prospective cohort assessment. Setting: Ninety NHs in Switzerland. Participants: Included 14,771 NH residents. Measurements: The Resident Assessment Instrument Minimum Data Set and the Nursing Home Confusion Assessment Method were used to determine follow-up of subsyndromal or full delirium in NH residents using discrete Markov chain modeling to describe long-term trajectories and multiple logistic regression analyses to determine predictors of the trajectories. Results: We identified four major types of delirium time courses in NH. Increasing severity of cognitive impairment and of depressive symptoms at the initial assessment predicted the different delirium time courses. Conclusion: More pronounced cognitive impairment and depressive symptoms at the initial assessment are associated with different subsequent evolutions of delirium. The presence and evolution of delirium in the first year after NH admission predicted the subsequent course of delirium until death. Copyright (C) 2012 American Association for Geriatric Psychiatry |

| 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. |

| Weldon, M. (2012), "Jointly modeling time-varying offending profiles and criminal career trajectories in a sample of sexual offenders. A multivariate approach to modeling criminal careers.". Master thesis. Department of Mathematics and Statistics, Lancaster University, 2012. |
| Abstract: The study begins by summarising three key topics of research in criminal careers of sexual offenders: explaining the observed bimodality of the age-crime curve for sexual offenders; determining whether rapists and child molesters follow well-separated, or overlapping criminal career paths; and assessing whether non-contact sexual offending is associated with serious sexual crime, and if so, which serious sexual crimes it is associated with. It is argued that these and other salient questions in the study of criminal careers of sexual offenders cannot easily be answered using trajectory models that aggregate crimes across types, or profile models that account for mix of crimes but do not take account of criminal career dynamics. Using data on 824 male sexual offenders from the Massachusetts Treatment Center, the study investigates four methods for the joint analysis of sexual offender trajectories and profiles. The four methods are: optimal matching with non-probabilistic clustering; ``constrained'' multivariate group based trajectory models; ``unconstrained'' multivariate group based trajectory models; and a Poisson-log normal factor model with posterior trajectory analysis of the factor scores. Optimal matching is found to be a useful way to summarise and visualise complex sequences of events, with the advantage that clustering can be performed without aggregating the data. However, without the ability to make inferences from findings its usefulness is limited to an exploratory role. The constrained and unconstrained multivariate trajectory models are compared, and it is found that neither one dominates the other in all contexts, and that both correspond to interesting theoretical hypotheses. It is suggested that the unconstrained models should be a starting point for modeling, since they make fewer assumptions and allow the appropriateness of the constrained model to be tested. It is demonstrated that the factor model can produce parsimonious trajectories for different types of criminal activity that are close to independent at each time point, but which are nevertheless highly associated (positively or negatively) over the life course. In applying the model, it is shown that a three factor model distinguishes between trajectories characterised by general crime, rape and child molestation. With regards to the research questions, all of the methods lend evidence to indicate the existence of bimodal trajectories, and that these trajectories exist at the individual level and are not an artifact of aggregation. However, it is shown that it is not possible to answer questions relating to associations between the occurrences of certain types of crime, using a dataset in which certain combinations of occurrence and non-occurrence are structurally missing. |

| Biemann, T. (2011), "A Transition-Oriented Approach to Optimal Matching", Sociological Methodology. Vol. 41(1), pp. 195-221. |
| 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. |

| Blanchard, P. (2011), "Sequence Analysis for Political Science". Working Papers of the Committee on Concepts and Methods, 32. International Political Science Association, 2011. |
| Abstract: Sequence analysis (SA) is a method to process sequence data, sequences being defined as series of states or events in the trajectories of statistical individuals. SA includes tools to code and format sequences, to compare them by pairs, to cluster them, to represent them in alphanumeric and graphical forms, to calculate specific statistics for sequences and groups of sequences, to mine sequences and to extract prototypical sequences. SA has been developing since the mid-1980s in the social sciences, after being imported from genetics and computer science. It has spread quickly to sociology and demography, and is now developing in history, geography, anthropology and political science. Some strong and original results have been achieved by means of SA, regarding for example the transition from education to work life and from work life to retirement. In this paper, I wish to show that SA presents a large potential for political science, through many, largely unexplored empirical applications. SA could soon enter the standard statistical toolbox, as a pragmatic, mainly descriptive approach to time-related phenomena. This paper intends to show the diversity of potential applications of SA, how to implement it and how it complements other methods |

| Casper, G. & Wilson, M. (2011), "Bargaining within Crises", In American Political Science Association Meetings, September 1-4, 2011, Seattle, WA |
| 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. |

Sont ainsi identifiés trois types de trajectoires vers l’insécurité : déclassement, insécurité intermittente et insécurité continue. Nous mettons en lumière la faiblesse du soutien de l’État-providence japonais envers les personnes en difficulté et sans aides familiales ou amicales qui tombent dans des situations extrêmes de précarité. |

| 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. |

| Bühlmann, F. (2010), "Routes into the British Service Class: Feeder Logics according to Gender and Occupational Groups", Sociology. Vol. 44(2), pp. 195-212. |
| 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. |

| Lesnard, L. (2010), "Cost Setting in Optimal Matching to Uncover Contemporaneous Socio-Temporal Patterns", Sociological Methods & Research. Vol. 38(3) |
| 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: 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. |

L'indication du diplôme ne permet pas de rendre compte des particularités diachroniques des parcours suivis : les inégalités devant la formation s'avèrent être aussi des inégalités du point de vue de l'itinéraire emprunté. L'éventail des trajectoires disponibles et la possibilité de s'en écarter pour réaliser un itinéraire « sur mesure » ne sont pas identiques d'une catégorie à l'autre.

| Griffin, A.L. (2009), "Analyzing Sequential Data From Geovisualization User Interfaces", In 24th International Cartographic Conference, ICC 2009, Santiago de Chile, November 15-21, 2009 |
| 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. |

We introduce a new methodology for clustering career-paths by combining statistical estimation of non-homogeneous Markov chains with self-organizing maps.

| 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. |
