This cross- sectional study consisted of an online questionnaire, completed by 158 MBO students and which measured academic stress, related constructs and coping strategies. Data was investigated through two multiple linear regressions: one investigating the whole sample and one investigating men and women separately. An independent samples t-test analyzed gender differences in self-compassion. Results indicated a positive association between academic stress and depressive symptoms in both the total sample and the two gender groups, as well as a negative association between self-compassionate coping and depressive symptoms. Self- compassionate coping was found not to have a moderating effect in the total sample, nor in either gender group. Moreover, no significant gender differences were found in either the amount of self-compassion students experienced, or its moderating effect. Findings showed that non- university students experience many of the same issues as university students do. Despite no moderating effect being found, a direct negative association between self-compassionate coping and depressive symptoms was established. These findings indicate that existing interventions for academic stress in university students need to be applied to non-university students, as such interventions could be of help in reducing this student population’s mental health issues. Additionally, interventions aimed at non-university students’ mental health should take self- compassionate coping into account as a possible protective factor for depressive symptoms.Show less

Part of multiple Roman fortifications along the Limes dating from 40 A.D. onwards, the cemetery was likely used as a burial ground for inhabitants of the Valkenburg fort or nearby vicus, a civilian settlement. The cemetery comprised at least 250 cremated individuals as well as 47 inhumations, which is a striking find that contradicts the common Roman practice of cremation. Due to these inhumated skeletal remains, the site provides an unique opportunity to employ osteoarchaeological analysis to reconstruct the lives of individuals that lived in the Roman Frontier region. This thesis utilizes cross-sectional geometry and bilateral asymmetry analysis to infer activity patterns among individuals at the Valkenburg-Marktveld cemetery, as current research on the differences in bone geometry between different demographic groups within Roman communities in the Lower Rhine area is limited. The study further investigates the factors and potential activity patterns that might influence those variations, such as biological age and sex. To do so, it builds on the initial osteoarchaeological study conducted by Lonnée and Maat (1998), who reported the estimated sex and age-at-death of each individual. Following this, each relevant bone in the upper and lower limbs was measured on various points to generate the indices for each point of measurement, as well as calculate the percentage directional asymmetry (DA%) and absolute asymmetry (AA%). The resulting values were then compared statistically between the biological sexes and age-at-death categories. While statistical significance is limited, the interpretation of data highlights the potential of these analyses in inferring activity patterns. Results from the analysis indicate that males tend to display more robust and symmetric upper and lower limbs than females, which are likely attributable to biological factors or a wider range of activities in males. Age-at-death categories exhibited inconsistencies with patterns described in other study, which is possibly due to natural variation or the limited preservation and availability of the skeletal material. Despite the limited number of individuals that could be examined, this thesis contributes valuable insights into the application of cross-sectional geometry and bilateral asymmetry analysis in osteoarchaeological studies, complementing historical data and broadening our understanding of activities in Roman frontier regions.Show less

Desperate to resolve the infection, patients were often subjected to prolonged and extensive treatments with toxic mercury. Unfortunately, osteoarchaeological study of syphilis is challenging due to the limited skeletal visibility of the infection. Moreover, historical evidence is sparse and often influenced by sociocultural stigma attributed to the venereal nature of the disease. This scarcity of data on syphilis in the early modern period has limited more holistic research into the disease and its treatment. Therefore, this study adopted a multidisciplinary approach to investigate syphilis and its treatment at St. Gertrude’s infirmary (1382 - ca. 1611) in Kampen, the Netherlands, where presence of the disease has been previously reported. Human skeletal remains (n=79) were re-examined with a focus on treponemal disease, following the scoring system laid out by Harper et al. (2011). The potential therapeutical use of mercury was investigated by conducting archival research and multiple trace elemental analyses. Using portable X-Ray Fluorescence Spectrometry (pXRF) and Inductively Coupled Plasma-Mass Spectrometry (ICP-MS), subsamples of the skeletal assemblage were assessed on the presence of mercury in human bone. Scanning Electron Microscopy with Energy Dispersive X-Ray (SEM-EDX) was conducted to assess the potential uptake of mercury in dental calculus on the teeth. Osteoarchaeological study identified several diagnostic cases of treponemal infection at the site (n=5 or 6.33%), as well as a number of cases with lesions suggestive of treponemal disease. This finding demonstrates the influence of treponemal disease, likely attributable to venereal syphilis, at St. Gertrude’s infirmary in Kampen, especially when compared to the prevalence of the disease in human skeletal assemblages from similar Dutch sites. Research into historical archives indicated that mercury was indeed used therapeutically in Kampen during the 18th century. However, it showed no direct evidence for syphilis or mercury treatment at St. Gertrude’s infirmary in the period of interest (1382 – ca. 1611). Unfortunately, elemental analyses revealed no substantial evidence for significantly elevated mercury concentrations, although interesting trends were found. In particular, both pXRF and SEM-EDX analyses did not result in absolute and quantifiable mercury concentrations. While ICP-MS analysis showed absolute concentrations of mercury in a subsample of bone material, interpreting and contextualising these results remains challenging. These observations may be explained by a lack of available mercury treatment in Kampen or a preference for other treatment methods. Nonetheless, this study helps to understand syphilis and its treatment in the early modern Netherlands and provides an evaluation of chemical analyses to detect mercury in archaeological bone.Show less

As such, it can serve as a useful area for activity reconstruction in the past. Though its function and evolution have long been studied, parts of it still need to be better understood. There is evidence to suggest that the fifth ray of the hand contributes significantly to grip strength and stability in a way that has so far gone largely ignored. The aim of this study is two-fold. First, it seeks to gain a better understanding of the function and use of the fifth digit in habitual activity on the basis of three postmedieval Dutch populations. Second, it investigates habitual activity and occupation among the individuals that belonged to these communities to gain a better understanding of the lives led by people in the post-medieval Netherlands. In order to achieve those goals, the study analyses activity patterns among hand entheses through the “Validated Entheses-based Reconstruction of Activity” (VERA) method. The method is applied to 3D scans of the hand bones of 43 adult individuals. Multivariate statistics, including principal component analysis, are used for the analysis of the entheseal attachment sizes. The analysis showed that the muscles of the fifth ray are recruited in both precision and power grips in different capacities. It suggests that the fifth ray is an important supporting structure that aids in the execution of power and precision grips through its opposing position to the thumb. It is also used to provide stability by pulling it towards the other fingers. The results of this study support the assumption that the fifth ray of the hand plays a crucial role in everyday manual activity. They also suggest that a deeper understanding of its role could provide additional insights into different kinds of grasping activities in the past. The analysis further showed that the three different groups exhibit different activity patterns. The lower-class urban individuals or Arnhem exhibit a trend towards more intense power grasping, while the higher-class urban individuals from Zwolle showed a tendency for precision grasping activity. This is consistent with historical records that suggest the Zwolle individuals had worked as merchants, investors, and in similar professions, while the working poor in the city of Arnhem were probably working in factories and in the local tobacco production. The individuals from the rural community of Middenbeemster fell somewhat surprisingly in the middle of the other two groups, with a sizeable number of individuals exhibiting precision gripping patterns. This suggests that, despite this community having mainly revolved around dairy farming, individual life experiences were likely quite varied. Future analyses of the fifth ray should expand on the groundwork laid in this study by increasing the sample size, looking into individuals from different contexts and time periods, and looking into potential connections between the fifth ray and the fourth ray, wrist, and forearm.Show less

This is an important issue due to the gap in literature and the increasing importance of media in society. Furthermore, the ISS act has caused public outcry in the Netherlands and citizens fear for their privacy and rights. The watchdog of the AIVD, CTIVD has published four reports investigating their conduct. Using these reports a benchmark of issues is created as indicator of good reporting to enhance accountability. This thesis has chosen to analyse the amount of coverage these issues receive in the media articles in 2018 and compare it to the occurrence of the issues in the reports. Limitations of this study are the lack of linguistic and contextual comparison and the lack of consideration of political affiliation of the news outlet. Furthermore, the CTIVD reports are considered as the ideal way to report in order to maximise intelligence accountable, which neglects the imperfection of the organisation. This paper concludes that in the 17 news articles that contain one or more of the benchmark issue(s), 6 out of the 8 relevant issues (75%) were extensively reported on in the media when comparing to the CTIVD reports resulting in a positive effect on the media’s ability to hold the AIVD accountable. Therefore, this thesis argues that the ability of the media to hold the AIVD accountable in news articles that cover the unlawful conduct is very high.Show less

Instead of viewing radicalisation as a process involving deep-rooted societal issues such as discrimination and social exclusion, a disproportionate focus is put on the ideological push factor that is Islam to understand and combat radicalisation. This article examines the degree to which Islamophobia has been present in Dutch policies on Preventing and Countering Violent Extremism (P/CVE) through discourse analysis. Previous research examined the effects of elements of Islamophobia being present in governmental discourse on the Muslim communities, but there showed to be a gap in the research on how this anti-Muslim sentiment is reflected and can be recognized in governmental texts. Ten Terrorist Threat Assessment Reports that were published in the early stages of the War on Terror were compared with the ten most recent reports based on the framework of elements of a closed and open view of Islam as established by the Runnymede Trust in 1997. The analysis reveals that elements of Islamophobia have been present ever since the War on Terror in the form of constructing Muslims as the enemy and overgeneralising various factions within Islam, but have seen an increase in recent years, leading current reports to reinforce Islamophobic sentiment. This research allows for elements of Islamophobia in government texts to be recognized and confronted.Show less

It uses a quantitative analysis of items from the Dutch Parliamentary Electoral Survey (2021) and POPPA (2018) to research whether the more salience is attached to economic, socio-cultural, and political issues by voters, the more important the chosen dimension will be for their vote. The examination provides data on voters’ and party positions on these three dimensions, and the binary logistic regression finds that the effect is strongest for the socio-cultural issues, but also somewhat significant for political issues, which confirms the importance of populism in contemporary Western European democracy.Show less

The register is aimed at tackling gambling addiction and protecting consumers. This study forecasts the likely success of CRUKS in meeting these public policy goals by way of comparison with the ROFUS self-exclusion register in Denmark, where a similar gambling regulatory environment exists, but which has also had its register in place for longer than in the Netherlands. Gambling exclusion registers such as CRUKS and ROFUS are examples of digital public sector innovation, with clear theoretical roots in behavioural economics, whereby the vulnerable gambler is offered a ‘one stop shop’ facility for (temporary) removal from gambling channels, while not prohibiting the less vulnerable and recreational player. The extension of the ROFUS register to land-based casinos in Denmark in late 2016 is employed as a cut-off point at which to test its effect on gambling activity in that sector. This policy intervention is shown to have a significant but steady downward effect on gambling activity, suggesting that such a register will likely have a similar effect on the gambling market in the Netherlands. This is particularly important to Dutch gamblers in light of the recent regulation of online gambling in the country, in light of the potential intensifying effects this channel has on problem gamblers.Show less

This new domain brought many opportunities, but also many new threats to governments and citizens worldwide. This paper focusses on one of the main cyber threats of this time: cyber espionage. This research discusses how the official position of the Dutch government regarding cyber espionage has evolved from 2011 onwards. As a heavily digitalized country that greatly contributes to the regulation of cyberspace and cyber espionage in international fora, the Netherlands is the ideal country to analyse. This is done by looking at policy documents and official statements of Dutch government officials at international fora. Two case studies – the DigiNotar hack in 2011 and the Organisation for the Prohibition of Chemical Weapons hack in 2018 – illustrate how policy is put to practice.Show less

They are responsible for 90% of poleward water vapor transport and have been linked toflooding and extreme rainfall events (EREs). While the impacts of this meteorological phenomenonhave been well-studied in some parts of the world, such as mountainous California, research on ARs in low relief regions is lacking. This study thus determinesto what extentARs are associated with EREs and precipitation in the Netherlands (NL) and whether this relationshipchangesspatially.NL was chosen as the study location as it is experiencing the effects of changing rainfall patterns and is a low-lying country with little relief. AR influences on one coastal city, The Hague, and one inlandcity, Maastrichtwereexamined. The scale of ARs is significantly larger than the surface area of NL, meaning that both cities are often affected by the same AR. Therefore, results between The Hague and Maastricht only differ slightly. By combining AR presence data with precipitation datathis study demonstrated that ~46% of all EREs are accompanied by an AReventin the two cities. Moreover, itwas found that 28.5% and 33.5% of all precipitation iscorrelated with AR occurrencesin The Hague and Maastricht,respectively. Lastly, rain days in Maastricht are1.9% more likely to be accompanied by an AR than in The Hague.This study supports the claim that ARs are an important factor in explaining EREs, which is highly relevant considering the predicted increase in AR occurrences due to climate change.Show less

The securitisation model analyses the securitising actor’s response to the threat. Further, it analyses whether the securitisation act enabled the securitising actor to implement drastic measures. This thesis uses the case study method and selected the cases with a shared perpetrator and objective. For the findings, this thesis concluded the following for the three cases. The Dutch government completed the securitisation act for the attempted OPCW hack but did not implement drastic policies. For the Bundestag hack, the Federal Government did not complete the securitisation act but did implement drastic measures. The United States completed the securitisation act and implemented drastic policies. Thus, the extent to which the securitisation model explains the response of the victim state differs in each case.Show less

This area is poorly researched compared to the city of Nijmegen in the west and the newly discovered auxiliary forts in Germany to the east. Roman fortifications were hypothesized to have existed on the higher peaks of the moraine, offering a commanding view over the wider area and connecting west to east. An analysis of the available literature indicates this part of the moraine might hold more Roman archaeological remains than is currently known, including villae and fortifications on the high peaks. In an attempt to predict and locate these, the AHN3 height map of the Netherlands is used for a visibility analysis and LiDAR visualization analysis of the area. The visibility analysis shows that several high peaks, most notably the Duivelsberg, are ideal locations for a watchtower which could act as a missing link in a signalling system between the fortifications in Nijmegen and those in Germany. LiDAR analysis indicates that several areas on the moraine likely contain undiscovered archaeological remains, including World War Two battle remains, prehistoric barrows, and urnfields. The research also demonstrates the strengths and shortcomings of using these digital methods to locate new archaeological remains. It is concluded that the moraine is a highly attractive area for future archaeological research into Roman Nijmegen or other periods.Show less
