Participation research has hitherto taken age, gender, socio-economic status, and ethnicity-related individual inequalities in political participation as independent universal categories and hence overlooked their simultaneous and interactive effects. Nor has it much considered the impact of the context in which individual inequalities are embedded. By exploiting the paradigm of intersectionality, we intent to examine in this thesis contextualized intersecting inequalities in political participation in the Western European context. To that end, we utilize a rich quantitative data set that combines all the waves of the European Social Survey (ESS) and apply a new methodological strategy. We make use of intercategorical approach of the paradigm of intersectionality and attempt to develop a multiple correspondence analysis of multilevel data as a means of relating individual inequalities to contextual factors and capturing contextualized unequal relations in political participation. We argue that individual inequalities in political participation are not mutually exclusive, but intersect with one another and coincide with the context in which they are embedded. We expect this thesis to contribute to the advancement of quantitative intersectionality research and to future policymaking on equality and non-discrimination in Western Europe in order to reduce inequalities and encourage the political participation of hard-to-reach individuals.

The phenomena of migration, as well as the policies and the representations associated with them, constitute a field concentrated in the paradoxical relationships between rights, their universality and their violations.This research aims to study the social representations of immigrant rights and tolerance towards the violations of these rights. It aims specifically to understand how these representations are shaped by experiences of institutional violence over the course of the biographical trajectories of immigrants and by the strategies they mobilise to cope with this violence. These phenomena will be studied with a focus on migration trajectories (namely, those of Portuguese immigrants in Switzerland). Qualitative and quantitative procedures will be articulated through the collection of life stories and life calendars, as well as the quantitative study of attitudes and social representations of the rights of migrants and of institutional violence towards migrants.

My PhD project aims to explore the career trajectories and the professional socialization of aspiring elites in the Swiss field of finance since the 2010s, focusing on graduates from finance master programs: How do young professionals enter the field of finance? How do they learn the rules of the game and how do they biographically construct their adherence to the norms and values of finance (what Bourdieu calls the illusio)? How do their experiences differ regarding their respective social origins and the resulting dispositions? What insights do their experiences provide about the structures and transformations of the field? This research adopts a multidisciplinary approach, integrating methodologies and concepts from educational studies, social mobility research and elite sociology.
The study centres around a case study of a cohort of 20 graduates from two Swiss universities, one in the French-speaking and one in the German-speaking region, who will be systematically accompanied and interviewed from their graduation through the initial years of their professional careers.

Despite progress in recent years, balancing professional and personal commitments within dual-earner relationships remains a significant challenge. Gender disparities in career disparities and income persist, particularly in Swiss society, where traditional labor divisions continue to obstruct the realization of a gendered-balanced workforce. This project mainly utilizes data from the Swiss Household Panel to explore these enduring patterns. The primary goal is to understand the complex nature of gendered task divisions among couples. Therefore, the first phase involves a multichannel sequence analysis to identify task division types and the factors influencing them. Subsequently, the project will focus on the long-term consequences of these divisions, considering gender, migration status, and socio-economic background. Building on these insights, the project will investigate the impact of critical life events, technological advancements, and normative changes on task division dynamics. Finally, it will assess the role of institutional and policy contexts, including legal frameworks and support structure, in shaping labor patterns. A comparative perspective may also be incorporated to deepen the analysis and broaden its implications.

This thesis project focuses broadly, first, on the influence of occupational group on economic (liberalism vs. redistribution) and cultural (progressive vs. traditional values) attitudes. Occupational groups are positioned quite distinctly from one another on these two axes. Using data from the European Social Survey (ESS), the project centres on how the occupational groups’ positions on these two attitudinal axes evolve over time. Data from the World Values Survey (WVS) will also be used to support a broader perspective, beyond the ESS’ European focus.
A second part of the thesis project deals with the effects of intragenerational occupational mobility on peoples’ position on these two main axes of political attitudes. This part of the project focuses on how occupational mobility affects political attitudes across time (instead of using a binary, before-after comparison). Potential anticipation effects in the time-period leading up to the change, as well as progressive post-change effects, can therefore be studied. Data will be pooled from panels (SHP, BHPS/Usoc, …) to allow for this. Difference-in-difference models, with asymmetric fixed-effects, will be used.

Quantitative data are prone to incomplete data. This phenomenon of missing data (MD) is almost impossible to avoid in many research areas such as healthcare or social sciences. When poorly managed, MD can result in misleading estimates and affect the overall validity of the study. Hence, MD presents a pervasive challenge in the design of studies, especially in longitudinal studies which are increasingly encountered in health and social scientific research.
To overcome this problem, many methods have been proposed so far, such as multiple imputation (MI) developed by Rubin (1977). MI is a powerful method that gives reliable results in a transversal framework. However, its application in the longitudinal context has been seldom discussed. Features of longitudinal data such as temporal structure of the data, correlations from one wave to another, and correlations within the same wave of data, represent a real challenge in the application of MI in a longitudinal context. In this thesis, I will address that gap by focusing on the consequences of using MI, and putting a particular attention on strategies to avoid possible pitfalls in applying MI in a longitudinal context. The main objective is to explore the influence of the imputation on the final results and to investigate the limits of MI in longitudinal data. In order to reach this objective, classic MI method, linear increments method, and linear mixed models will be used to impute MD. Comparison of these three methods will be conducted using simulated data and a real longitudinal dataset.

I use for my dissertation the Becoming parent data. I’m interesting in the appearance of the gender master status (Levy et Krüger, 2000 et 2001). It’s a concept which explains the traditionalisation that couples experience during the transition to parenthood by the institutional constraints. With this aim in view, I’m at present working on the links between the intentions expressed before and after the first child birth by couples about child care tasks sharing between them and what they really do. I’m interesting too to understand which factors impact on these intentions and practices. On the long view, I’m interesting in how couples foresee the transition to parenthood in terms of work, child care (by external person or institution) and familial tasks (housework and child care) sharing and what they actually do.

This project explores social cohesion in multicultural contexts, focusing on Switzerland. It
aims to understand how diverse cultural identities and stereotypes impact social integration and
belonging. Social cohesion, essential for stability and inclusivity, is often disrupted by stereotypes and
prejudices, particularly regarding ethnic names and identity markers, leading to discrimination and
limiting opportunities for minorities. The research examines identity perceptions and stereotypes
through ethnic names in Switzerland, assesses discriminatory practices in employment, housing, and
childcare using field experiments, compares discriminatory practices and integration policies across
nine European countries through a comprehensive survey, and investigates adaptive strategies and
resilience of second-generation immigrants in Switzerland via surveys and interviews. By examining
identity perceptions, cumulative discrimination, cross-national differences, and minority adaptive
strategies, this study aims to provide insights for fostering inclusive societies and inform effective
integration policies. The findings will contribute to both academic discourse and practical
applications in enhancing social cohesion in multicultural environments.

Mental health problems are identified as being part of the leading health-related problems among young individuals. In fact, the wellbeing of young people does not improve and seems to even decline across the years. To address this problem, it is crucial not to overlook the influence of family interrelationships. Parents indeed play an important role in children’s wellbeing and the influence also goes in the other direction. However, literature about the interrelationships between parents’ and child’s mental health is scarce and mostly focuses on mothers and their children. Moreover, most studies are based on cross-sectional data that do not allow to measure mental health interrelationships accurately and assess their directionality, and none used Swiss longitudinal data yet. Gaining a better understanding of the interrelations between parents’ and children’s mental health would be beneficial for policy development, prevention and to better treat mental health problems themselves.
Following a life course perspective, the goal of this thesis is to contribute to research on parents' and children’s wellbeing by assessing their interrelationships in mental health and their directionality. Secondly, differences across subgroups will be examined (gender, place of origin and socio-economic conditions) and across family structures (children living with two parents, single parents and stepparents). Finally, the role of welfare policies on family mental health will be investigated.

Done within the frame of SNSF funded project "People-Opinion Networks: A study of polarization in word embeddings and social networks in Switzerland and Southern Africa", this thesis will study polarization and radicalization using the People-Opinion Networks model. This model uses machine learning and social network analysis, integrating relational networks and the linguistic features of actors to better understand how group polarization occurs. It will do so in three case studies. The first is the The Red Pill, an online space where men come together to discuss men issues that attracted attention by becoming a misogynistic forum. This first case will be a longitudinal study of the group dynamics of the forum while a second study will look at the most radicalized individuals of this group and their radicalization across time. The third study will be the Spanish Civil War. This project will focus on the groups that made up the Left in the conflict that, while having a common enemy, were ideologically divided. This historical case study will have more data limitations, providing an opportunity to investigate how to better integrate historical data into new methodologies and give a new perspective to this significant period in Spanish history.

His main research interests are the sociology of the family, life course, longitudinal analysis and qualitative methods. His thesis studies families' life course and living conditions in French-speaking Switzerland with a lone parent experience. Based on the research project sample "The multiple paths of lone parenthood" (2012-2022), his thesis focuses on their adaptations to different life domains, the adoption of new roles and their family reconfigurations with a longitudinal and qualitative perspective.

In my thesis dissertation, I am investigating union dissolution among both married and unmarried parents. The increase in divorce in Western countries is part of a larger trend that has been affecting the family as an institution since the 1960s: while traditional families are becoming increasingly fragile, other forms of family are emerging, such as unmarried couples with children. Divorce is often mentioned as an example of an event that challenges the life course (which is supposed to follow a set of social rules and expectations) as well as the identity, social roles, and status of those who have experienced it. However, as union dissolutions have become increasingly frequent and concern more various family structures, I hope to understand whether divorce and separation can still be considered as critical life events, and if so, in which contexts. To answer these questions, I will use a mixed-methods design (methods and data) with four approaches that are embedded in a life course perspective: 1) a focus on the interdependence of family-work trajectories before and after the event, 2) an emphasis on the effects of time (sequence and duration) on the event/ transition in question, 3) an examination of the influence of the relevant institutional and social contexts, and 4) methodological innovations to answer such questions.

Equality of opportunity is widely acknowledged as a fundamental principle of justice. However, its exact definition remains a subject of debate, and current methods of measuring it are found lacking. This thesis aims to address these concerns by introducing both theoretical and methodological innovations. First, it distinguishes between a 'liberal' and a 'radical' definition of equality of opportunity. The former recognises as fair the inequalities arising from different natural talents, while the latter includes genetic endowments, such as social origin, gender, or ethnicity, in the category of morally arbitrary factors that should not form the basis for justifiable inequality under either definition. Second, it takes into account two levels at which inequalities arise, namely between families, and within them. In fact, our approach complements the traditional sibling similarity measure, quantifying the first dimension, with individual level factors explaining inequalities within families. For both aspects, some critical elements are taken into account. From a theoretical perspective, the assumption that effort constitutes a just base for inequalities because individuals have control over it is challenged. Concerning methodology, the estimation of liberal inequality of opportunity is refined by accounting for polygenic scores as a measure of the equitable transmission of genetic endowments from parents to offsprings.

Mounting evidence across disciplines suggests that early childhood environments have a lasting impact on later life outcomes. Among others, early childhood education (ECE) programs have been regarded as a human capital investment policy that improves not only children’s outcomes but also promotes the reconciliation of work and family life for parents, particularly for mothers. My thesis will analyze the impacts of mandatory pre-primary education in Switzerland, a change in compulsory school established by the Intercantonal Agreement on Harmonisation of Compulsory Education (HarmoS Agreement). The first part of the analysis concentrates on the impact of pre-primary education on children’s academic outcomes and intergenerational educational and social mobility. The goal is to investigate universal ECE as a policy strategy for reducing social inequalities and equalizing educational opportunities. The second part is focused on the effect of preschool attendance on maternal labor outcomes. Thus, it is centered on measuring the impact of preschool attendance on maternal employment and gender inequalities in the labor market. My thesis aims to contribute to the discussion of early childho

This purpose of this thesis is to investigate the link between custody arrangements and child’s well-being and particularly to gain a comprehensive understanding of the factors that impact child well-being after parental separation or divorce with an approach grounded in the life course theory. Firstly, the aim is to characterize along the socio-structural dimension the physical custody arrangements in terms of distribution and characteristics of families after parental separation or divorce in Switzerland. We will particularly try here to understand the distinctive role of social selectivity into different custody arrangements. Then, the second goal is to look at how those custody arrangements change or stay stable and why it does so by identifying under which socio-structural conditions custody arrangements change in terms of duration, stability, and trajectory. In the second part of this thesis, the aim is to investigate the impact of the grand-parental separation or divorce on the current situation, namely on the current parental separation or divorce, custody arrangement and child well-being. Finally, the last chapter will assess whether child well-being varies as a function of post-separation physical custody arrangements and, if so, to determine how and also what explains such variation using intact families as a comparison group.
