Show moreUntil the 17th century, the Dutch coastal region of Zeeland ranked among Europe's most urbanized areas, driven by thriving international trade networks. People living in this time of flourishing economy benefitted enormously from it in terms of employment opportunities and working conditions, which were reportedly better than in the rest of the Low Countries. However, the rapid growth of Zeeland's urban centers likely presented increasing challenges for the population in terms of accessing essential resources, including food, clean water, and housing. In the 19th century, Zeeland's economy ultimately faced a significant downturn due to the decline in the maritime trade, leading to a substantial reduction in its urban population. Examining patterns of urbanization and economic histories that differ from the commonly studied thriving industrial contexts in bioarcheological research, as exemplified by Zeeland, is a crucial yet relatively underexplored facet in our efforts to understanding the human past. To address this gap, this study investigates the impact of urbanization on the health of Zeeland's inhabitants over time by analyzing nonspecific stress markers (i.e., cribra orbitalia, porotic hyperostosis, and linear enamel hypoplasia) and chronic maxillary sinusitis in a sample of 246 individuals from three urban sites dating from 1030 to 1800 CE. Our analysis of skeletal remains reveals significant differences in the prevalence of porotic hyperostosis, linear enamel hypoplasia, and sinusitis between the medieval and post-medieval periods. These findings suggest that de-urbanization and economic decline adversely affected the health and well-being of the populations under study, influenced by factors such as working conditions and food availability. This study provides a new perspective on bioarcheological approaches to urbanization, shedding light on the intricate realities of urbanization in Zeeland and offering important insights into its complexities.

Show moreThis dissertation examines the educational positions of children of immigrants in the Netherlands from 1980 to 2020. In particular, the influence of migration background and socioeconomic factors on educational positions is studied. Findings reveal substantial progress in education for migrant children overall, especially among the second generation, younger cohorts, and girls with a migrant background, indicating promising upward mobility within the education system for many of these children. The family environment impacts educational outcomes, with socioeconomic background playing a crucial role. Higher parental incomes correlate with higher education levels for children in both the short and long term. Additionally, the living environment affects outcomes such as school dropout rates, especially among boys from migrant backgrounds in larger cities. They are more prone to leaving education prematurely than their female or non-migrant peers. Despite institutional barriers and discrimination within the education system, these children demonstrate an upward trend in education, highlighting the need for further research incorporating discrimination as a factor.

Show moreSince the opening of the first CLIL department in the Netherlands in 1989, tweetalig onderwijs (‘bilingual education’) has expanded into a national network of over 130 secondary schools, serving a population of around 37,000 learners. While academic interest in the field has also seen growth and diversification, the pace of practical developments and the lack of a structured research agenda have led to research becoming fragmented and lagging behind practice. This chapter provides an overview of the Dutch CLIL context followed by a critical review of research into organisation, implementation, outcomes and experiences in Dutch bilingual education. The chapter concludes with a reflection on the ways in which future research could support further developments in practice. Show less

Show moreTHIS PAPER ADDRESSES THE QUESTION, who were the people who were buried at the early medievalNorth Sea emporia? Conclusions about the mercantile character of the North Sea emporia are often based on portablematerial culture. In recognition of the fact that it is difficult to draw conclusions about the identities of people basedon finds assemblages, two pilot projects have been completed that involved bioarchaeological analyses of cemetery pop-ulations associated with these sites. The first of these, the Investigating the Dead in Early Medieval Domburg project,undertook multi-disciplinary analyses of the (very small) surviving burial population from the mostly destroyed sitesin the Domburg area (Netherlands), combining isotope analysis, radiocarbon dating, biological anthropology, dendro-chronology, and provenancing and study of previous use of coffin wood. The second, the Medieval Migrants of theNorth Sea World project, inventoried available isotopic evidence for human remains from emporia sites in England,the Netherlands and Scandinavia, alongside contextual archaeological information. This paper presents both projects,providing the detailed information from Domburg in its wider, international context, and highlighting the need for acomprehensive research agenda to fill current gaps in our understanding of early medieval emporia populations.

Show moreThe overall aim of this dissertation was to study the contribution of a syndemics framework to understanding and addressing persistent health disparities. Departing from an interdisciplinary approach, the dissertation attends to research questions on syndemics indicators, contextual drivers for syndemics, the intergenerational nature of syndemics, and possibilities for early public health interventions in Katwijk, a former fishing town in the Netherlands. An epidemiological study described the three most prevalent disease clusters in Katwijk. A qualitative life course study found a first indication that syndemic vulnerability is potentially intergenerational, and that syndemic processes can be countered. A mixed method study showed that while challenging, a family-engagement approach can elicit positive effects on families’ health and wellbeing. The ethnographic study described the hurdles for implementing family-focused health promotion for multifaceted health conditions, such as childhood obesity. This dissertation establishes that the syndemics framework provides tools to identify past and present factors on the complex pathways to persistent poor health, which in turn point at directions for breaking patterns of generational health. The findings highlight a need for multisystem approaches in which stakeholders develop a thorough understanding of a community’s history and past legacies with institutions, and professionals are equipped with the necessary knowledge, attitudes and skills for community-based and family-focused interventions.

Show moreBackground:Identification of risk factors and causes of stroke is key to optimize treatment and prevent recurrence. Up to one-third of young patients with stroke have a cryptogenic stroke according to current classification systems (Trial of ORG 10172 in Acute Stroke Treatment [TOAST] and atherosclerosis, small vessel disease, cardiac pathology, other causes, dissection [ASCOD]). The aim was to identify risk factors and leads for (new) causes of cryptogenic ischemic stroke in young adults, using the pediatric classification system from the IPSS study (International Pediatric Stroke Study).Methods:This is a multicenter prospective cohort study conducted in 17 hospitals in the Netherlands, consisting of 1322 patients aged 18 to 49 years with first-ever, imaging confirmed, ischemic stroke between 2013 and 2021. The main outcome was distribution of risk factors according to IPSS classification in patients with cryptogenic and noncryptogenic stroke according to the TOAST and ASCOD classification.Results:The median age was 44.2 years, and 697 (52.7%) were men. Of these 1322 patients, 333 (25.2%) had a cryptogenic stroke according to the TOAST classification. Additional classification using the ASCOD criteria reduced the number patients with cryptogenic stroke from 333 to 260 (19.7%). When risk factors according to the IPSS were taken into account, the number of patients with no potential cause or risk factor for stroke reduced to 10 (0.8%).Conclusions:Among young adults aged 18 to 49 years with a cryptogenic ischemic stroke according to the TOAST classification, risk factors for stroke are highly prevalent. Using a pediatric classification system provides new leads for the possible causes in cryptogenic stroke, and could potentially lead to more tailored treatment for young individuals with stroke.

Show moreIn this project we examine whether homicide ‘clusters together’ with other adverse health outcomes in the Netherlands, focusing on child mortality, suicide, sexual risk behavior, and substance abuse. We expect moderate-to-strong correlations between homicide and the other adverse health phenomena (hypothesis 1). Further, we expect that these correlations will be reduced when social disorganization is controlled for (hypothesis 2).The study used population-level data between the years 1996 and 2019, for each of the 40 local regions of the Netherlands. We applied a multilevel correlation procedure to evaluate correlations between homicide and the other adverse health outcomes. Correlations between homicide and the other adverse health outcomes were modest. That is, we found only limited evidence for clustering between homicide and the other adverse health outcomes. The patterns of clustering that did occur, suggested that social disorganization in the region promotes risk-taking behaviors in the population, which ultimately increases rates of homicide, abuse of illegal drugs and births to adolescent parents.Project materials, syntax and supplementary information can be found on the Open Science Framework at https://osf.io/jd5yu/.

Show moreThe aim of this chapter is to contribute to the debate on deconstructing the gender binary, toexplore notions of experiencing shame and violence, and also to identify key points of self-concept ingenderqueer people, by running a survey in three different countries: Greece, the UK and the Netherlands.The survey is the first to explore the impact of this gender- binary discourse and the experience of shameand violence within this frame, within the genderaqueer community in a comparative perspective. Thechapter contributes to the debate on perceptions of masculinity and femininity in association with shameand violence, while reconnoitring the role of culture as a driver of these perceptions and how that role leadsto the re-evaluation of the self along with the sense and impact of shame as a relational process with the self and the society. The survey approaches shame and violence, not only in terms of how they are perceived by the genderqueer community, but also of how they are expressed, e.g. in a passive way (directed violence against a person) or active way (person as actor engaging in violent behaviour) in everyday life. The application of different perspectives on confronting the binary, power and shame provides a critical take on the gender-based debate and on the crux of self-concept and identifies breaks with existing thinking and practice that are essential to any reform of gender recognition policy.

Show moreOver the past ten years, seven Dutch Universities have built a sustainable exchange with seven institutes in Cuban healthcare. The exchange was initiated by the Leiden University Medical Centre and the University of Medical Sciences of Havana. Cooperation with Cuba was chosen as Cuba has excellent primary healthcare and has a strong focus on prevention and public health. These were considered important due to the major contribution of non-communicable diseases to morbidity and mortality in the Netherlands. Exchanges have occurred with Dutch health professionals and students visiting Cuban healthcare institutions and Cuban postgraduate students studying in the Netherlands. There has been an increased awareness of the importance of public health and prevention in Dutch professional organizations following the exchange. The exchange has also helped to break the scientific and economic US blockade of Cuba and resulted in joint publications. In this review we described the process, key aspects, results and lessons learned in this process. Collaboration between Cuba (a middle income) and the Netherlands (a high-income country) is possible. Show less

Show moreBackground and Purpose: Tumor recurrence, a characteristic of malignant tumors, is the biggest concern for rectal cancer survivors. The epidemiology of the disease calls for a pressing need to improve healthcare quality and patient outcomes. Prediction models such as Bayesian networks, which can probabilistically reason under uncertainty, could assist caregivers with patient management. However, some concerns are associated with the standard approaches to developing these structures in medicine. Therefore, this study aims to compare Bayesian network structures that stem from these two techniques. Materials and Methods: A retrospective analysis was performed on 6754 locally advanced rectal cancer (LARC) patients enrolled in 14 international clinical trials. Local tumor recurrence at 2, 3, and 5-years was defined as the endpoints of interest. Five rectal cancer treating physicians from three countries elicited the expert structure. The algorithmic structure was inferred from the data with the hill-climbing algorithm. Structural performance was assessed with calibration plots and area under the curve values. Results: The area under the curve for the expert structure on the training and validation data was above 0.9 and 0.8, respectively, for all the time points. However, the algorithmic structure had superior predictive performance over the expert structure for all time points of interest. Conclusion: We have developed and internally validated a Bayesian networks structure from experts' opinions, which can predict the risk of a LARC patient developing a tumor recurrence at 2, 3, and 5 years. Our result shows that the algorithmic-based structures are more performant and less interpretable than expert based structures. Show less

Show moreThis qualitative case study uses a life-course approach to explore syndemic vulnerability in a former fishing village in the Netherlands. Building on four years of fieldwork in a low-income neighborhood, we explored salient themes between and across families and generations. Elderly community members (> 65 years) were interviewed to map village history and explore how contextual factors have affected family life, health, and wellbeing since the 1940s. We systematically traced and compared processes leading to or from syndemic vulnerability by studying seven families across three generations. Adults with at least one of clustering diseases, their parents (when possible), and their children participated in semi-structured life-course interviews. A complex interaction of endemic social conditions, sociocultural normative processes, learned health be-haviors, and disheartening life events shaped families' predispositions for a syndemic of psychological distress, cardiometabolic conditions, and musculoskeletal pain. Educational attainment, continued social support, and aspirational capabilities emerged as themes related to decreasing syndemic vulnerability. This study demonstrates that syndemic vulnerability is potentially intergenerational and reveals the need for culturally sensitive and family-focused syndemic interventions. Future longitudinal research should focus on unravelling the pathogenesis of the clustering of psychological distress, cardiometabolic conditions, and musculoskeletal pain among young people.

Met in zijn bagage een dosis moderne landbouwkennis uit Wageningen, werkte hij aan programma’s in de tropen waarbij overdracht van westerse kennis het doel was. De aanpak blijkt niet te werken. Hij plaatst vraagtekens bij de toepasbaarheid van de westerse kennis in situaties waar de ecologie, economie en cultuur zoveel verschillen. In samenwerking met lokale deskundigen uit India, Bolivia en Ghana wordt onderzocht hoe lokale wereldbeelden, waarden en kennis een rol spelen. Daarvoor wordt gewerkt aan een onderwijsmethode voor endogene ontwikkeling en aan een benadering voor co-creatie van wetenschappen uit verschillende tradities en wereldstreken. De internationale ervaringen worden in verband gebracht met de huidige crisis in de landbouw in Nederland en monden uit een pleidooi voor klimaat- en natuurvriendelijke landbouw. Show less
