Essays on Well-Being Comparisons, Gender Dynamics, and Economic Resilience. 

This thesis employs big data and computational methods to investigate aspects of human behavior and well-being across four diverse studies.

Chapter 1 introduces a new measure of financial vulnerability using survey data to assess the resilience of households in seven EU countries during income shocks, such as those triggered by COVID-19. Using microsimulation techniques, it finds that employment protection benefits significantly reduced vulnerability, though disparities remain for certain groups, notably younger individuals, single parents, women, and non-EU-born individuals.

Chapter 2 leverages over 60 million online hotel reviews to explore cultural heterogeneity in self-reported assessments of well-being across nationalities. The study reveals that differences in scale usage for identical experiences correlate with broader life satisfaction scores, highlighting the complex influence of national characteristics on subjective well-being measures and challenging universal comparisons.

Chapter 3 narrows this focus to examine the impact of minor events, such as a football match, on well-being reports, showing that responses can shift significantly depending on outcome, thus questioning the stability of subjective assessments in cross-national analyses.

Chapter 4 utilizes machine learning and audio analysis to study peer interactions in academic seminars, particularly regarding gender dynamics. Results reveal a pattern where female speakers face more frequent, earlier, and often negatively toned interruptions. These findings contribute to the literature on gender biases in professional settings.

Together, these studies demonstrate how computational approaches and high-dimensional datasets can advance economic research, providing new insights into well-being, cultural reporting biases, and gender dynamics.

BUILDING MINDS BY SOLVING PROBLEMS Exploring Computational Thinking and STEM Integration in Vocational Education

Computational Thinking (CT) and STEM education are vital for developing problem-solving skills in today’s rapidly evolving technological landscape. As automation and emerging technologies reshape workforce demands, vocational education plays a key role by offering hands-on learning aligned with real-world applications. This dissertation examines the integration of CT and STEM in vocational education through six studies. 

Study 1 establishes a theoretical framework that aligns computational thinking and STEM integration with vocational education and training’s practical, hands-on nature. By identifying synergies between computational thinking and STEM, the study positions computational thinking as a problem-solving approach, adaptable across vocational disciplines. Studies 2 and 3 develop and validate instruments to measure students’ motivation and computational thinking skills. Key findings reveal diverse motivational profiles, gender differences in engagement, and a disconnect between self-reported and demonstrated computational thinking abilities, emphasizing the need for robust assessment tools. Studies 4 and 5 explore teachers’ attitudes and classroom practices using a framework based on technological pedagogical content knowledge. These studies highlight the role of self-efficacy and perceived relevance in shaping teaching practices and underscore the need for tailored professional development to address varying confidence levels among educators. Study 6 applies the computational thinking and STEM framework in the 'Social Robot' project, a case study demonstrating how integrated computational practices engage vocational education and training students in problem-solving. Findings reveal the importance of adaptable instructional strategies to meet the diverse needs of technical and non-technical students.

Collectively, these studies contribute to a deeper understanding of how computational thinking and STEM integration can be implemented in vocational education settings.

The effectivity of professional development trajectories for school leaders: opportunities and challenges for sustainable professional development and school development

It is generally believed that school leadership contributes to efficiency and equity in learners' academic performance. The focus on their important role ensures that school leaders consistently apply leadership strategies that are more goal-oriented and demonstrate the effects of their policies on learning outcomes. Therefore, it is essential that professional development initiatives for school leaders adequately focus on aspects of effective leadership. Professional development of school leaders asks for high-quality professional development trajectories that promote concrete transfer and sustainable implementation of the content provided.

This dissertation presents research on the effectiveness of a two-year professional development trajectory for school leaders in primary and secondary education in Flanders and the Brussels region. In five sub-studies, it investigated the experienced impact of the specific organizational and didactic approach of the trajectory on the sustainable professional development of school leaders and on school development, both during and after the trajectory.

The research contributes to a better understanding of the key factors for a thoughtful organization of and approach to professional development trajectories for school leaders. In addition, it provides valuable insights for school leaders, school boards, and the government to facilitate sustainable professional and school development.

Meat at steak. Exploring masculinity in meat consumption and reduction on personal and interpersonal levels. 

On a warm summer evening, the smell of grilled meat fills the air as men gather around the barbecue. This familiar scene reflects a broader pattern where meat consumption is deeply tied to identity, particularly masculinity. Across many Western cultures, meat—especially red meat—is associated with power, strength, and dominance, reinforcing traditional male identity norms. This connection contributes to men's resistance to plant-based diets despite growing awareness of environmental, health, and ethical concerns. Consequently, men consume more meat than women and hold more positive attitudes toward it. Meat avoidance, by contrast, is often perceived as incompatible with traditional masculinity, creating social tensions between meat eaters and meat avoiders. However, the specific role of gender identity and intergroup contact in shaping these attitudes remains underexplored.

This dissertation investigates the intersection of masculinity, identity, and meat consumption through four empirical studies across two levels: personal and interpersonal. At the personal level, an online survey examines how both sex and gender influence meat consumption attitudes and behaviors. A second study analyzes publicly posted tweets (now on X) to explore how men and women express their views on meat in digital spaces.

At the interpersonal level, an online experiment examines how men engage with social media posts about meat consumption, simulating real-life digital interactions. The final study investigates face-to-face discussions between meat eaters and meat avoiders, exploring how intergroup and intragroup dialogues shape attitudes toward dietary choices. Together, these studies provide a comprehensive look at how masculinity and identity influence—and are influenced by—attitudes and interactions around meat consumption.

This research moves beyond biological sex to highlight the social and identity-driven dimensions of dietary behavior. It underscores the role of traditional masculinity norms and the importance of intergroup contact in fostering openness to plant-based diets. Practically, these findings offer insights for encouraging dietary change by promoting respectful dialogue and challenging restrictive gender norms. By targeting young men—a demographic with high meat consumption—this work contributes to efforts addressing the environmental, health, and social challenges posed by excessive meat consumption, paving the way for a more sustainable future.

Designing theory-based, evidence-based, and strategic communication materials to increase radon protection intentions. 

Radon, a naturally occurring radioactive gas, is the second leading cause of lung cancer worldwide. Despite the severe health risks, radon testing and mitigation remain insufficient. This issue is situated on multiple levels, ranging from the individual to the political, economic, social, and physical environment. While effective communication is essential to bridge this gap, radon health communication remains underexplored. This dissertation examines how strategic, theory- and evidence-based communication can enhance public engagement with radon-related behaviours. In the first phase of this research, the current communication was analysed. A systematic review of radon-related mass media interventions reveals that most campaigns rely on informational messaging, often failing to evoke personal relevance or emotional engagement. Moreover, in focus group workshops homeowners emphasised the need for communication strategies that extend beyond awareness-raising, addressing practical concerns such as financial support and regulatory measures. Participants also suggest tailoring messages to different behavioural stages, using approaches such as humour, personal letters, and testimonials. In the second phase, communication materials were developed and tested. An online experiment compared the impact of narrative-based and statistical messages on risk perception and behavioural intentions. Findings indicate that narratives are more effective in increasing personal and general risk perception while also strengthening intentions to seek information, test for radon, and consider mitigation. These results inform the development of a large-scale social media campaign, Radon Buster, designed to motivate individuals to take action. The campaign, implemented across Austria, Belgium, Ireland, and Slovenia, uses Facebook ads incorporating narratives, humour, and social norm nudges to attract attention and drive engagement. A controlled online survey experiment finds that exposure to these ads positively influences information-seeking intentions. A subsequent live Facebook study demonstrates strong audience engagement, with click-through rates and interaction metrics suggesting that social media can serve as an effective platform for radon risk communication. Overall, the findings highlight that radon communication must go beyond merely providing information, but should engage audiences, and align the messages with the decision-making process. While no one-size-fits-all solution exists, integrating social, emotional, and cognitive factors can enhance the effectiveness of communication strategies. This dissertation underscores the importance of a multi-level approach, combining stakeholder-targeted messaging with broader environmental interventions to ensure radon risk communication translates into meaningful action.

Making sense of absence, distance, and presence: The role of time and space in the meaning-giving processes underlying loneliness in old age

In recent years, the topic of loneliness has garnered significant public attention in Flanders, as evidenced by the substantial growth in its media coverage and the emergence of policies aimed at mitigating and preventing it. Research findings have repeatedly demonstrated the association between loneliness and various health problems, including depression, chronic diseases, and early mortality, thereby raising public awareness that loneliness is a ‘silent killer’ with a detrimental impact on the quality of life across all age demographics. The increasing proportion of life spent in retirement, attributable to changes in life expectancy, underscores the necessity for strategies that promote inclusion, good health, and mental well-being in old age. Such strategies are not merely a matter of fundamental human rights and needs but also benefit society at large. In this regard, researching and formulating strategies to detect, prevent, and alleviate loneliness among older adults is paramount.  By identifying specific attributes that shape the perceptual and conceptual processes by which older adults construct and interpret their social realities and create mental images of absence or presence, distance or proximity, loneliness or belonging, this dissertation seeks to explore the conditions that empower older adults to effectively navigate their spatial and temporal surroundings and attain social connectedness, or, conversely, prevent them from doing so. To that end, the dissertation is structured into three sections: the first part is theoretical, while the subsequent parts are empirical.  The first chapter delineates five core characteristics of loneliness and further elucidates that it constitutes an adverse emotional response to perceived absence, emanating from a series of perceptual and cognitive-evaluative processes in which relational standards and expectations, as well as the capacity to compensate for the perceived absence of human or non-human objects with an internally felt presence or mental image of these objects, are involved.  The subsequent two chapters draw on several principles of grounded theory to systematically analyze two theoretical subsamples derived from a larger data set of 615 in-depth interviews with individuals aged 65 and above. The first study indicates that the dynamic interplay of four evaluative dimensions guides older adults’ interpretations of specific properties of video calling and, subsequently, shapes how they situate video-mediated interactions within the broader realm of their social interactions, allowing them to perceive either distance or closeness, absence or presence. The second study suggests that older adults’ mental representations of past, present, and future spatial settings serve as stable anchoring points, enabling them to (re)construct temporal horizons and contextualize their current living environment. Depending on whether or not older adults are successful in making aspects of their living environments their own and filling in the perceived gaps left by past experiences of loss and exclusion, as well as those anticipated in the future, they perceive either the absence or presence of a place called home, which, in turn, contributes to feelings of loneliness or belonging, respectively. The anchoring points and attributes identified in this dissertation provide researchers with multiple points of departure for further study of the topic, both empirically and theoretically, and allow practitioners and policymakers to seamlessly translate the findings presented into multi-layered loneliness prevention and intervention strategies, which are necessary given the multidimensional and multidisciplinary nature of the phenomenon.

Dream and Nightmare Issues: Interest Group Influence and the Logic of Agenda-Setting

This dissertation examines the agenda-setting influence of interest groups, focusing on their ability to promote ‘dream’ issues while preventing ‘nightmare’ issues from reaching the formal policy agenda. While existing research has extensively explored interest groups' role in later policymaking stages, their impact at the agenda-setting stage remains understudied. To bridge this gap, the dissertation examines how organizational characteristics, lobbying strategies, and issue-specific conditions interact to affect interest groups' agenda-setting influence.

Empirically, the study examines the European Union, with a specific focus on the Green Deal agenda. Using a mixed-methods approach, it integrates expert interviews with public officials, media content analysis, and interviews with interest representatives to evaluate interest groups' agenda-setting influence across 65 policy issues spanning climate, energy, transport, agriculture, economy, health, and food safety—33 of which became policy priorities, while 32 were excluded from the agenda. This comprehensive dataset allows for a systematic evaluation of the factors that facilitate or constrain interest groups’ ability to shape the formal policy agenda.

The findings contribute to three key debates in political science. First, they refine theoretical perspectives on interest group influence by integrating both positive and negative agenda-setting within a single analytical framework. Second, they advance methodological discussions on measuring lobbing influence by combining four different assessments of interest groups’ effectiveness in the agenda-setting stage. Third, they engage with normative debates on democratic governance, examining whether interest group lobbying enhances or distorts the representativeness of policy agendas. Overall, this dissertation provides a comprehensive account interest groups’ ability to exert agenda-setting influence.

Implementing team teaching: Exploring effective teaching behaviour and the professional identity of beginning team teachers.

Team teaching has emerged as a promising collaborative teaching strategy to tackle the challenges teachers face in the teaching profession. However, transitioning to team teaching presents challenges for teachers unfamiliar with collaborative practices. Despite its potential, limited research has explored how beginning team teachers experience and implement this collaborative model. This dissertation aims to address this gap by investigating (a) the effective teaching behaviour exhibited by beginning team teachers and (b) the development of their professional identity during the first year of team teaching. Additionally, it explores the impact of formal professional development initiatives on these aspects.

Study 1, a qualitative study, investigated beginning team teachers' perceptions of the added value of team teaching in realising effective teaching behaviour. Sixteen team interviews were conducted, revealing that teachers perceived team teaching as particularly beneficial for more complex teaching behaviours, such as adaptive teaching and activating learning. However, they found less value in aspects like teaching learning strategies. Teachers also highlighted team teaching as a valuable professional development strategy, enabling them to learn from colleagues, refine their practices, and enhance lesson organisation.

Study 2, a mixed-methods study, examined students’ perceptions of effective teaching behaviours in team-taught lessons. A survey (n = 428) and focus groups (n = 15) revealed that students rated less complex teaching behaviours, such as creating a safe and stimulating learning climate and providing clear instruction, more positively (and thus more present in team-taught lessons) than more complex behaviours like adaptive teaching. Students identified learning gains and increased support as key benefits of team teaching but noted occasional confusion due to inconsistent explanations between teachers. The study also found that team teaching in multi-grade classrooms led to lower student ratings on all dimensions of effective teaching behaviour.

Study 3, a longitudinal study, tracked the evolution of teachers’ professional identity over the first year of team teaching, using survey-based data gathered on four measuring moments. Findings showed that occupational commitment and autonomous motivation remained stable, while controlled motivation increased due to external pressures. Self-efficacy improved gradually, due to growing confidence in shared teaching responsibilities. Factors such as pedagogical comfort and successful collaboration contributed positively, whereas role ambiguity and interpersonal conflicts hindered professional identity development.

Study 4, a longitudinal video observation study using 96 recordings, examined the evolution of effective teaching behaviour during team teaching. The study identified five distinct teams’ trajectories: consistently struggling, declining, stagnating, improving, and fluctuating. Overall, less complex behaviours, such as clear instruction and classroom management, improved over time, whereas more complex dimensions of effective teaching behaviours, such as activating learning and adaptive teaching, remained challenging. Teachers who received intensive professional development, including coaching, demonstrated the most significant improvement in adaptive teaching.

This dissertation contributes to a deeper understanding of the process of implementing team teaching, highlighting the complexities of teaching together and the crucial role of structured support. While team teaching facilitates professional growth and fosters collaboration, mastering complex teaching behaviours remains difficult. Formal professional development, particularly when including coaching, enhances both teaching effectiveness and professional identity development. Policy and practice should support structured training initiatives to optimise the benefits of team teaching, ensuring that teachers receive adequate guidance to navigate the transition from solo to collaborative instruction successfully.

To know it all? How party position knowledge varies between citizens, political parties, and policy issues. And why it matters. 

In this dissertation, I examine how party position knowledge (PPK) varied during the 2019 Belgian federal elections. PPK is the factual & verifiable information about political parties’ policy positions stored in people’s memory. Representative democracy assumes that citizens are informed about the policy preferences of parties so that they can better align their choices with parties that reflect their own policy preferences (Pierce, 1999). However, previous research suggests that voters are generally uninformed about politics and that knowledge is not distributed equally (Bennett, 1995; Delli Carpini & Keeter, 1996). I replicate findings from previous research to examine how PPK varied between voters (inter-voter differences in PPK) during the 2019 Belgian elections. However, I also move beyond inter-voter variation and ask how party, issue, and voters’ perceptions of these relate to voters’ PPK (intra-voter differences in PPK). Finally, I ask how the clarity of party communication shapes what voters know about their issue positions.

Empirically, the study draws on data from the RepResent Belgian Panel survey to develop a fine grained measure of PPK, inspired by a systematic exploration of previous research on PPK. I supplemented the voter data with a content analysis and party surveys. I find that that PPK varies with abilities (cognitive skills, education), motivation (interest, ideological extremity), and opportunities (media exposure). Older, highly educated, politically engaged men tend to have higher PPK. While traditional media exposure enhances PPK, reliance on social media does not significantly improve it.

Beyond individual-level variables, I find PPK varies strongly with party and issue characteristics. Voters are more knowledgeable about traditional left-right issues, opposition parties, and ideologically extreme parties. Moreover, issue ownership perceptions—the belief that certain parties are best suited to handle specific issues—may enhance voters’ ability to correctly identify party positions.

Finally, party communication strategies may play a key role in shaping PPK. Voters are more knowledgeable about positions that are emphasised and consistently communicated in traditional media. This highlights how parties influence what voters know through message clarity.

The Prism of academic optimism. Measuring, understanding and fostering its role in school improvement. 

Academic optimism is a multidimensional framework encompassing academic emphasis, trust in students and parents, and feelings of efficacy. It holds strong potential for enhancing student outcomes. Positioned within the discourse on equity and excellence, this dissertation aims to deepen the theoretical and empirical foundations of academic optimism while informing practical efforts for school improvement.

Through a mixed methods design, the research refines the measurement of academic optimism at both the teacher and school levels, resulting in valid and reliable instruments. Two key conceptual advancements are introduced: the separation of trust into trust in students and trust in parents, and the nuanced differentiation between school- and teacher-level constructs. These refinements provide a strong foundation for more accurate analysis and application.

Next, this dissertation examines the variation of academic optimism across educational settings. Findings reveal strong associations between school academic optimism and teacher academic optimism, while classroom and school composition have only modest effects. Educational track proves more influential, with lower levels of teacher academic optimism reported in vocational pathways. Teachers’ attribution patterns differ notably between schools with high or low optimism, revealing contrasting narratives about students, colleagues, and the work itself – highlighting the need to foster internal, instable and controllable attributions that support a more optimistic school culture.

Finally, the dissertation explores how leadership can foster academic optimism. Principals who adopt “performance management for academic optimism” not only help align teachers, students, and parents around shared educational goals, but also reinforce the academic optimistic culture of their school.

Together, these findings contribute to a deeper understanding of academic optimism as a driver of school improvement. This dissertation offers refined measurement tools and practical insights for cultivating optimism in schools, empowering teachers and school leaders to support more equitable and effective learning environments.

Fair and square? The role of recognition in promoting fair and resilient flood risk management in Flanders and internationally. 

Throughout Europe, climate change and urbanisation are increasing flood risks. While Flanders has mostly experienced small-scale flooding so far, future climate scenarios suggest that large events – such as the July 2021 floods in Wallonia – are also possible here. Physical interventions in the water system through dikes and flood retention areas play an important role in managing these rising flood risks. But the social dimension of flood risk management (FRM) is often overlooked. This is problematic, as floods do not affect everyone equally. Some groups are more vulnerable to the impacts of flooding, either due to their location (e.g., proximity to rivers or the coast) or their socioeconomic and demographic characteristics – such as low-income households, older adults, or those with low-quality homes. This is referred to as social vulnerability to flooding in this PhD research. 

Based on policy analysis and expert interviews in Flanders, including cross-country comparisons with England, Finland, and France, this study explored (1) to what extent social vulnerability is recognised and addressed in FRM, (2) how expert knowledge shapes the levels of recognition, and (3) how broader societal trends influence attention to social vulnerability. The findings show that social vulnerability is rarely a central concern outside of emergency planning and crisis management for flooding. Recognition appears to depend heavily on the FRM expert’s disciplinary background and knowledge base, shaping how professionals understand and prioritise social vulnerability in policy and practice. Furthermore, trends such as individualising governance, neoliberalism, and the shift of responsibility to citizens in FRM risk reinforcing vulnerability and deepening inequality, as vulnerable groups may not be able to bear that burden.

Recognition is essential to strengthen fairness in FRM, because without acknowledging people’s differing needs and perspectives, they remain unprotected and more vulnerable to future flooding. This research calls for greater attention to who is vulnerable and why, better use of existing social data, and policy integration and interdisciplinary collaboration to develop more just and resilient flood risk policies.

Signed, Sealed, Delivered? A Cross-Contextual Investigation of Determinants, Communication Strategies and Voices that Shape Vaccination Confidence and Decision-Making. 

Vaccination remains one of the most effective interventions for preventing disease and promoting health equity, yet its success is increasingly challenged by growing distrust and emotional uncertainty. In recognition of these challenges, in 2019, the World Health Organization identified vaccine hesitancy as one of the top ten threats to global health. The COVID-19 pandemic further exposed these dynamics, as countries with strong technical capacity did not always succeed in reaching high vaccine uptake, revealing a critical disconnect between vaccine availability and uptake.

This dissertation explores vaccine confidence as a complex, socially shaped phenomenon, with a particular focus on the role of communication in enabling or undermining trust in vaccination. It draws from five empirical chapters that investigate how people make sense of vaccination in a changing landscape, examining intentions, emotional concerns, healthcare provider perspectives, and participation in vaccine trials. Different communication strategies are explored, including autonomy-supportive messaging, two-sided communication, and targeted approaches.

Three conceptual cornerstones guide the analysis: currents of vaccination behaviour, capturing the emotional and social undercurrents that drive doubt or refusal; orchestrating the message, examining how framing and tone affect perceptions and motivation; and voices of vaccination, highlighting the role of trusted messengers in shaping public engagement. Together, these insights point to the need for communication strategies that move beyond persuasion, towards approaches that foster relevance, respect autonomy, and strengthen trust in public health.
