We aimed to quantify the risk of comorbid disorders in SUD youth with ACE-history. Additionally, we aimed to examine relations between ACEs, overall household experience, and general distress. We used cross-sectional YIT-study data from interviews with Dutch youth (aged 16-22) upon SUD treatment entry for cannabis, alcohol, or stimulant use. We measured ACE-types experienced up until 15 years of age, past-year DSM-5 disorders, general distress (DASS-21), and overall household experience rating. Logistic regressions quantified relations between ACE sum score and anxiety, depressive, behavior, and any disorder. Higher ACE sum scores related to increased risks for a(n) anxiety (OR = 1.12, highest odds = 2.84; χ2(1) = 6.71, p < .010; Nagelkerke R2 = 0.2), depressive (OR = 1.21, highest odds = 5.43; χ2(1) = 18.11, p < .001; Nagelkerke R2 = 0.6), behavior (OR = 1.20, highest odds = 5.24; χ2(1) = 17.41, p < .001; Nagelkerke R2 = 0.6), and any (OR = 1.25, highest odds = 7.58; χ2(1) = 17.26, p < .001; Nagelkerke R2 = 0.7) disorder. Exploratory analyses revealed that frequency of parental fighting, being hit/abused, getting belittled, emotional neglect, physical neglect, insufficient household income, long parental sickness, and overall household experience positively related to DASS-21. In a hierarchical regression analysis with all ACEs and overall household experience, only emotional neglect related to DASS-21 (B = 3.68, t(373) = 2.41, p = .017). Overall household experience did not improve the model (F(12) = 3.51, p < .001; R2change < .001). In hierarchical regression analyses containing ACE sum score and overall household experience, overall household experience was not uniquely related to DASS-21 (t = -0.22, p = .824; R2change < .01). In conclusion, ACEs relate to comorbid disorders in SUD youth. Our exploratory research suggests that ACE frequency might influence this relation, while overall household experience does not further explain this relation. Further research should investigate which ACE measures (a.o., type, frequency) strongly relate to SUDs and psychopathology and examine improved treatment options.Show less

This discrepancy may partly stem from the complex and multifaceted nature of migration, with the climate factors influencing economic opportunity and conflict, making it difficult to differentiate between people that migrate for climate reasons and people that migrate for other reasons, such as economic opportunities. However, it more likely arises from people being trapped within their increasingly uninhabitable homes, because they do not have the capacity to move or willingness to leave their home. Therefore, policymakers and researchers should redirect their attention to immobility, as the ‘trapped populations’ are an urgent and underexposed problem. This thesis will examine the term 'trapped populations,' by using conceptions of Zickgraf (2019, 2023) and De Shalit (2011) and clarifying the complexities inherent in their immobility. I will argue for ‘the right to stay’ as the most protective right for the interests of the trapped populations, as it respects the importance of a home in a person their life.Show less

Political parties in European countries have responded differently to this influx of people. This study aims to clarify the relationship between the agenda of these political parties and the European migration crisis. Based on qualitative research, a content analysis was used to study the differences between left-wing, right-wing and centre-parties and how the European migration crisis has impacted these points of view. The analysis shows that political parties with different ideologies about migration react differently to the crisis. The European migration crisis has little to no effect on the agenda of left-wing parties and right-wing parties, but a major effect on the agendas of centre-parties.Show less

Deze scriptie gaat in op de manier waarop doven en slechthorenden worden gezien. Hierbij zal vanuit verschillende perspectieven worden gekeken wat het inhoudt om doof te zijn. De perspectieven van de horende maatschappij zullen tegenover die van de doven en slechthorenden worden gezet. Het perspectief van de horende maatschappij is op dit moment dominant. Om te analyseren waarom dit het geval is zal worden gekeken hoe de horende maatschappij het zintuig horen waardeert. Vervolgens zal worden gekeken hoe doven en slechthorenden in het dagelijks leven functioneren zonder het zintuig horen. Zij bewijzen dat het zintuig horen niet nodig is om goed te kunnen functioneren in de maatschappij. Op dit moment leven doven en slechthorenden in een wereld die niet altijd toegankelijk is. Er worden wel veranderingen gedaan om de maatschappij toegankelijker te maken, maar zijn dit wel de veranderingen die doven en slechthorenden zelf graag zien? Er is sprake van een spanningsveld tussen doven en slechthorenden en de horende maatschappij en dit spanningsveld zal in deze scriptie worden geanalyseerd.Show less

The human right to development, as established in the 1986 Declaration, recognizes a right to continuous improvement of life, irrespective of the negative environmental consequences related to this development. There is thus a need to review the human right to development in the context of climate change. In this thesis, I argue for a ‘threshold conception’ of the right to development, as it should be understood as a right to an unconditional process of development till the fulfillment of basic needs. Thereafter, development – then considered economic growth – should be consistent with the concept of sustainability. Moreover, I argue in favor of the adoption of the OHCHR’s Draft Convention on the Right to Development (2020) because it recognizes the triangular interconnectedness of development, the protection of human rights, and climate-related obligations. The convention establishes duties regarding climate mitigation, adaptation, and combatting climate injustices for states and the international community, which can both realize the right to development as the objectives of the human rights approach to climate change.Show less

In deze scriptie werden twee structurele MRI-maten geëvalueerd: grijze stofdichtheid (48 predictoren) en subcorticale volumes (14 predictoren). Deze scriptie onderzocht wat de toegevoegde waarde van subcorticale volumes bovenop grijze stofdichtheid is. Hierbij werd verwacht dat I) grijze stofdichtheid accurater was voor de classificatie van Alzheimer dan subcorticale volumes, maar dat II) subcorticale volumes nog wel iets zouden toevoegen aan grijze stofdichtheid. Om dit te onderzoeken, is data gebruikt van 249 participanten afkomstig uit twee verschillende studies. 76 participanten hadden de diagnose Alzheimer en de overige 173 participanten waren cognitief gezonde ouderen. Er zijn drie modellen gebruikt: een model van grijze stofdichtheid (48 predictoren), een model van subcorticale volumes (14 predictoren) en een combinatiemodel van grijze stofdichtheid en subcorticale volumes (62 predictoren). Voor alle modellen is een logistische regressieanalyse met geneste kruisvalidatie uitgevoerd. Het model van grijze stofdichtheid had een AUC-waarde van 0.897 en een MGA-waarde van 0.822. Het model van subcorticale volumes had een AUC-waarde van 0.807 en een MGA-waarde van 0.769. Het gecombineerde model had een AUCwaarde van 0.897 en een MGA-waarde van 0.841. De eerste hypothese werd bevestigd, aangezien grijze stofdichtheid belangrijker was voor de classificatieaccuratesse dan subcorticale volumes. De tweede hypothese kon niet worden bevestigd, aangezien subcorticale volumes weinig tot niets lijken toe te voegen aan grijze stofdichtheid voor de classificatieaccuratesse van Alzheimer. Deze kennis kan gebruikt worden om toekomstige classificatiemodellen van Alzheimer te verbeteren.Show less

When it comes to psychedelic rituals, there are several important factors to take into account, such as the setting, dosage, and type of substance consumed. This paper examines the effects of virtual ceremonies on psychedelic experiences. The study utilized an online self-report questionnaire that was sent 1-2 days after the ceremony conducted by retreat company Spinoza. The gathered data were analyzed using thematic qualitative analysis. The categorization and themes were agreed upon by two independent researchers. The themes presented relate to the improvement of mental health and physical comfort along with insightful personal journeys. Further evaluation of the research suggested that the findings provide a general idea about the effects of digital format on the psychedelic experience. It has been found that with digital platforms on psychedelic experiences, individuals can experience clarity of unsolved issues, improved self-regulation, as well as improved emotional and mental states.Show less

In their experiment, van Putten and colleagues (2007) tried to decouple the inaction inertia effect by using ambiguous information. Their results yielded that ambiguous information did in fact decouple. However, the authors came to these conclusions by using optional stopping and p-hacking. This influenced the reliability of the results, so we decided to replicate this study, for good research practices and because it can give us valuable insight into how decoupling works when given an attractive offer. We made use of the replication recipe of Brandt and colleagues (2014) to conduct the replication.Show less

This paper explores the intricate relationship between disgust and visual attention, employing the eye-tracking method. Drawing insights from primate studies, habituation, and human facial expressions, the research aims to address three key questions: Does gaze aversion occur in humans when exposed to disgusting stimuli, extending avoidance behavior into the visual domain? Do individuals exhibit prolonged attention to facial area, indicating a social imperative to assess the risk of pathogen contamination? How does gaze aversion change with repeated exposure to disgust-inducing stimuli? The study employs three conditions, including scenes of feces ingestion in the test condition, to assess total looking time. Results reveal significant gaze aversion towards feces as compared to control conditions, supporting the hypothesis of avoidance behavior. Participants displayed prolonged attention to faces during non-disgusting conditions, challenging assumptions about social necessity for risk assessment. Repeated exposure across trials to disgust-inducing stimuli did not significantly alter gaze behavior, highlighting the nuanced nature of responses to aversive stimuli. Discussion of the findings and implications are also addressed.Show less
