It explores the transformation of these fortifications, such as moats and ramparts, which once marked urban landscapes across Europe. Over time, these defensive structures became redundant, and most were either fully or partially destroyed, leaving behind traces. The land once occupied by these city fortifications has since been repurposed for various uses, one of which being green spaces. The thesis focuses not on the reasons behind these repurposing decisions but on their consequences. As such the main question that the thesis is answering is: How do decisions made in the past regarding the repurposing of land formerly occupied by historical city fortifications influence present-day urban greening efforts and green space allocation in the cities of Copenhagen and Groningen? Examining how these decisions have influenced the current distribution of green space and the urban greening agendas in cities, for this thesis Copenhagen and Groningen. By understanding the impact of past policies and planning strategies on the development of these former fortification sites, the thesis sheds light on how these decisions continue to shape contemporary urban environments. The thesis underscores the enduring influence of these land-repurposing decisions on today’s urban greening efforts. It highlights their significance for urban landscapes and cultural heritage and the current distribution of urban green spaces and urban greening initiatives. The study provides valuable insights into how past land use decisions continue to affect urban greening agenda efforts in the present day.Show less

Additionally, it focused on optimal integration of mental health care into gender-affirming care according to TGD individuals. Both were within the framework of an ongoing investigation at the Zaans Medical Centre. The quantitative data analysis consisted of intake questionnaire data of twenty-five TGD individuals, variables were derived from sections of the intake questionnaire. For the qualitative data analysis, seven semi-structured interviews were held with TGD individuals. The characteristics of TGD individuals consisted of self-reported psychological distress and well-being. Their relationship to requested mental health care intensity was studied through Spearman rank order correlations. The demographics included age, educational level, ethnicity, employment status, experienced income, and gender assigned at birth. Their association with requesting mental health care was explored through chi-square tests. A thematic analysis with semantic approach was performed to analyse the data. No significant correlations were found between demographic variables and mental health care requests at admission. The correlation between self-reported psychological distress and mental health care intensity was χ2 = -.003, p = .987, for self-reported psychological well-being and mental health care intensity χ2 = -.001, p = .997. Thematic analysis of interview data yielded three overarching themes: motives for seeking mental health care, recommendations for integrating mental health services into gender-affirming care, and desirable attributes of mental health care providers. Reasons for refraining from or seeking mental health care included experiencing psychological distress or good psychological well-being, experiences due to gender dysphoria, acceptance of themselves, and experienced lack of support. Suggestions for optimal mental health care integration were better and more provision of (mental) health care and travel distance to mental health care. Qualities of the ideal mental health care professional were having certain character traits such as being accepting and being specialized in TGD. Overall, this research emphasizes the importance of knowledgeability and empathetic and inclusive qualities in mental health care professionals in the treatment of TGD individuals suggesting its importance over mental health care professionals’ gender identity.Show less

Understanding the factors that influence vegetable intake is vital for promoting healthy development in children, as unhealthy eating habits can increase the risk of diseases like cardiovascular conditions, cancer, and diabetes. A cross-sectional study was conducted with a sample of 256 mother-child dyads (age children M = 4,68, SD = 0,42). Participants were recruited through email lists and child health centers in four Dutch provinces, targeting mothers about to introduce solid foods to their 4-6 month-old infants The data in this study was collected from the same sample of children, but when they were 24 months old. Information about the variables was gathered using multiple questionnaires: Compl-Eat, Meals in Our Household, CFPQ, and CEBQ-T. Results show that less picky children consume significantly more vegetables on average than picky children, with an average difference of 38.64 grams. However, no significant effects were found for parental encouragement or the frequency of family meals at the table on vegetable intake. Possible explanations for the lack of significant results include the skewed data distribution and potential social desirability bias in parental reporting. Future research should aim to precisely define and measure 'encouragement' and 'meals at the table', considering factors like frequency, method, and context. This will lead to the development of more precise measurement tools, improving the accuracy and reliability of findings. These insights are crucial for developing effective interventions to promote vegetable consumption in children and improve their overall health.Show less

Selective mutism shares similarities with social anxiety disorder. The cause of selective mutism is unknown, although several factors appear to be involved. The current study examined whether children with selective mutism have deficits in their inhibition and mental flexibility. Using parent questionnaires and a neurocognitive task for the children, inhibition in daily life, inhibition on a cognitive task, flexibility in daily life, flexibility on a cognitive task, and the social anxiety of both silent and non-silent children were assessed. A total of 33 children between four and six years old participated in the study, including 16 silent and 17 non-silent children. The results imply that inhibition and flexibility as behavioral characteristics are not the same constructs as inhibition and flexibility as cognitive functions but should be used to complement each other. Silent children were found to have more difficulty suppressing their responses on a cognitive task compared to the non-silent group. This difference was not observed for inhibition measured in daily life. It is suggested that silent children may struggle to suppress cognitive reactions for instance anxious thoughts in new situations while being capable of controlling impulses at a behavioral level. Additionally, silent children did not differ in their cognitive task-based mental flexibility from non-silent children, but they did differ in their mental flexibility in daily life. One explanation for this difference may be that environmental influences, such as stress, may prevent a child from effectively applying certain skills. Furthermore, in the present study of young children mental flexibility skills in daily life explained about a significant portion of the variance in social anxiety.Show less

Higher intake of vegetables appears to aid in preventing overweight. Since food preferences form before the age of 2, understanding factors influencing children's vegetable intake is crucial. Parental vegetable intake predicts children's vegetable intake, but research on the mother-child relationship in this context is limited, especially regarding young children under the age of 2. This study examines the relationship between maternal and child vegetable intake among children aged 11 to 14 months, exploring the potential moderating roles of maternal body mass index (BMI) and exclusive breastfeeding. Method: Data were drawn from the "Baby's First Bites" study, involving 240 mother-child pairs from the Netherlands, with 121 pairs included in this analysis. Children's vegetable intake was measured using Compl-eat, while mothers' vegetable intake was measured using the Food Frequency Questionnaires (FFQ). One multiple regression and two moderation analyses were conducted, with the mother's education level included as control variable. Results: Results indicated no significant association between maternal and child vegetable intake. Moderation analyses revealed that neither maternal BMI nor exclusive breastfeeding moderated this relationship. Even after accounting for the mothers' educational levels, the results remained unchanged. Discussion: These results are contrary to the hypotheses. Possible explanations for these findings include the young age of the children in this study, which may prevent them from applying modeling as a possible working mechanism between maternal and child vegetable intake. Also, methodological limitations such as the use of Compl-eat and the limited duration of exclusive breastfeeding could explain the lack of an observed association. Future research could investigate whether altering methodologies reveals a previously unnoticed association between mothers' and children's vegetable intake, and explore the underlying mechanisms of this relationship to clarify the effectiveness of increasing mothers' vegetable intake as a preventive measure against childhood overweight.Show less

A sensitive and responsive parent provides comfort and security to the child when needed (Bowlby, 1969). Various factors may play a role in parental sensitivity. This correlational study examined whether factors such as child temperament, parenting self-confidence, and parental mental well-being contribute to the degree of parental sensitivity. Thirty-two respondents participated in the study. Sensitivity was measured through observations, while child temperament, parenting self-confidence, and parental mental well-being were assessed using various validated questionnaires. The results showed that child temperament, parenting self-confidence, and parental mental well-being did not determine the degree of parental sensitivity. Despite the lack of a found correlation, it remains important to conduct further research on sensitivity and the factors that play a role in it. Sensitivity can be enhanced through appropriate support of the parents, leading to more sensitive responses to the child.Show less

Due to a lack of research and the complexity of the disorder, much remains unclear about the etiology and contributing risk factors of SM. More knowledge about the risk factors can contribute to early identification of children that are prone to developing SM. This may lead to better treatment outcomes, as earlier treatment is preferred. Methods: This quantitative, cross-sectional case-control study investigates if there is a relationship between facial emotion recognition and social anxiety in 4- and 5-year-olds that are exceptionally quiet in social situations. Additionally, this study tried to identify whether parental behavior has a moderating effect. This was done by performing independents samples t-tests and multiple regression analyses. 16 silent children (M = 5.1 years, SD = 0.64) and 17 healthy controls from the same group (M = 4.8 years, SD = 0.52) participated in this study. The children performed an affect recognition subtest and parents filled in online questionnaire about their child. Results: Results showed that the quiet children had higher levels of social anxiety compared to the controls, with a medium, negative effect (r = -.4). Additionally, parents of quiet children were found to show less positive parenting compared to the controls. No group differences were found in facial emotion recognition. Regression analysis showed a negative, but non-significant, relation between emotion recognition and social anxiety, in both the quiet children and the control group. Positive parenting was negatively correlated with social anxiety but did not show a moderating effect on the relation between social anxiety and emotion recognition. Discussion: According to this study, emotion recognition cannot be seen as a risk factor for social anxiety. Positive parenting is associated with lower social anxiety in the child. However, the direction of this relation remains unclear. Replication of this study with a clinical population is advised, as well as further research on the causal relation between social anxiety and parenting behavior.Show less

I focus on marginalised groups whose experiences often diverge from mainstream perspectives. Through case studies such as the Minha Casa Minha Vida project in Brazil and Hyde Park in the United States, this thesis highlights how these communities infuse spaces with personal and collective memories, influencing their interactions with the environment. These studies suggest that standardised urban planning policies may overlook the lived realities of marginalised communities, leading to social sustainability initiatives that fall short of addressing their needs. By examining the complex social, historical, and economic factors that shape human-environment relations, the thesis proposes a reimagined approach to urban planning that could foster more inclusive, equitable and supportive urban spaces.Show less

While crochet is still being gendered as a craft, the study aims to understand the motives and the factors that contribute to the sense of belonging within the community. It also unravels the importance of crochet intertwined with a form of feminist standpoint:crochet can convey feminist statements and actions, when they empower women.Show less

Therefore, a deeper understanding of the underlying mechanisms may help improve the treatment. Inhibitory learning has been a recently developed approach, stating that new fear associations must be actively developed. One proposed strategy has been that of expectancy violation, in which threat expectancies are actively challenged during exposure. Actively experiencing a mismatch between expectancy and reality is supposed to benefit learning and thus improve exposure success, yet results have been mixed. The aim of this study was to expose the mechanisms of expectancy violation by analyzing the types of expectancies experienced by PTSD patients. Furthermore, the effects of the strength of these expectancies and the extent to which they change in strength during exposure on treatment success was tested. In a clinical assay, participants (N = 60) were randomized across two groups, which both received exposure therapy. The experimental group’s exposure treatment was designed to enhance expectancy violation. In both groups, PTSD symptoms were measured at baseline and follow- up, and threat expectancies were measured right before and right after exposure. Results showed that both threat expectancies and PTSD symptoms reduced significantly. However, baseline expectancy strength did not have a significant effect on the amount of PTSD symptom reduction, both in the total and the experimental group. Furthermore, the amount of expectancy change did not predict PTSD symptom reduction either. A full ranking of expectancy types was provided.Show less

Brooding rumination is a symptom and a risk factor for depression. The default mode network (DMN) is active during brooding rumination. Inadequate suppression of this network obstructs activation of the central executive network (CEN), essential for performing cognitively demanding tasks. While previous research linked DMN suppression to depression, this has not been investigated in a healthy population. This study examined potential gender differences in the time required to switch from the DMN to the CEN in a healthy sample. Additionally, it investigated whether switching time was positively related to brooding rumination and whether this relationship differed between genders. Lastly, it explored whether functional connectivity (FC) between the DMN and the subgenual anterior cingulate cortex (sgACC) was related to brooding rumination. Results indicated a faster DMN-CEN switch in men compared to women. No relationship was found between switching time and brooding rumination in either men or women. Lastly, brooding rumination showed no relationship with sgACC-DMN FC. This study proposes a slower DMN-CEN switch as a possible neural mechanism for higher rates of depression and relapse proneness in women compared to men. Moreover, it suggests that DMN suppression may not underlie brooding rumination as a risk factor for MDD. Researchers developing preventive measures for depression aimed at reducing brooding rumination may consider targeting other neural mechanisms than DMN suppression. Future research should explore these alternative neural mechanisms to support the development of preventive measures for the onset and relapse of depression.Show less

Als deze zelfregulatie niet tot stand komt, spreken we van zelfregulatie falen. Hierbij hoort ook het ervaren van een setback, een terugval in het naleven van een gedragsdoel. Om de kans op setbacks zo klein mogelijk te maken, moeten we begrijpen hoe individuen reageren op deze setbacks. In deze thesis wordt onderzoek gedaan naar het belang van gedragsdoelen en welke psychologische constructen invloed hebben of worden beïnvloed door het ervaren van een setback. Deze thesis onderzoekt daarnaast het verschil tussen approach-oriented en avoidoriented doelen in relatie tot subjectief succes bij gedragsverandering. Vanuit de literatuur werd verwacht dat doelen met betrekking tot fysieke gezondheid de belangrijkste gedragsdoelen waren. Daarnaast werd als hypothese gesteld dat approach-oriented doelen meer subjectief succes opleveren dan avoid-oriented doelen. Methoden. Met een steekproef van 167 participanten werden verschillende statistische analyses toegepast om antwoord te geven op de drie onderzoeksvragen. De resultaten duiden op een significant onderscheid tussen beide typen doelen, waarbij approach-oriented doelen aanzienlijk hogere gemiddelde scores op subjectief succes vertonen dan avoid-oriented doelen. In de context van de eerste onderzoeksvraag blijkt dat het verhogen of reguleren van wekelijkse sportactiviteiten het meest voorkomende doel is, terwijl het verhogen of reguleren van gezonde voeding het daaropvolgende meest gangbare doel is. De tweede onderzoeksvraag wijst op een algemene positieve perceptie van doelbereiking onder deelnemers, waarbij approach-oriented doelen, zoals het verhogen van gezonde voeding, meer succesvol lijken dan avoid-oriented doelen, zoals het reduceren van alcoholinname. Echter tonen de resultaten aan dat deelnemers die zich richten op het verhogen of reguleren van sportactiviteiten zich over het algemeen niet significant succesvoller voelen dan degenen die zich concentreren op het verhogen of reguleren van gezonde voeding, Conclusie. De bevindingen suggereren dat het streven naar gewenste resultaten een verhoogd gevoel van succes teweegbrengt in vergelijking met het vermijden van ongewenste resultaten. Dit impliceert praktische implicaties voor interventies gericht op gedragsverandering, waarbij een nadruk op approach-oriented doelen een effectieve strategie lijkt te zijn. Echter wijst dit onderzoek op enkele beperkingen, zoals een beperkte steekproefomvang en de mogelijkheid van vertekening door zelfrapportage. Toekomstig onderzoek zou baat hebben bij een representatievere steekproef en longitudinale ontwerpen om een dieper inzicht te verschaffen in deze dynamiek.Show less

Om de negatieve gevolgen van externaliserend gedrag te voorkomen, is het belangrijk om de mechanismen erachter beter te begrijpen. Het doel van dit onderzoek is om te kijken of deze relatie daadwerkelijk bestaat en of een laag zelfbeeld deze relatie versterkt. In een cross-sectioneel onderzoek met 80 kinderen en hun ouder(s), werden ouderlijke kritiek, het externaliseren van de kinderen en het zelfbeeld van de kinderen gemeten aan de hand van vragenlijsten en een interactietaak. De resultaten toonden dat er geen relatie is tussen kritiek van de ouders en externaliserend gedrag van het kind. Ook versterkte een laag zelfbeeld deze relatie niet. Het blijft echter nog de vraag op welke manier deze drie variabelen met elkaar in verband staan en of factoren zoals het geslacht van het kind of verschillen tussen de ouders hier iets mee te maken hebben. Onderzoek hiernaar zou meer duidelijkheid geven rondom dit vraagstuk.Show less

EMSs have been categorized into five broader schema domains. Transdiagnostic depressive symptoms entail depressive symptoms observed across various psychological disorders. We studied the relative contribution of the five EMS domains on transdiagnostic depressive symptoms in a cross-sectional within-subjects design. The sample consisted of students from Leiden University (N = 125) participating for course credit or monetary rewards, of which 91.2% were assigned the sex female at birth and 8.8% male (median age = 19, IQR = 2). Participants completed measures of the Young Schema Questionnaire 3 - short form (YSQ-S3) and the DSM-5 self-rated level 1 cross-cutting symptom measure – Adult (DSM-XC). Pearson correlations were inspected between each EMS domain and transdiagnostic depressive symptoms. A multiple regression analysis including the total scores of the five EMS domains as predictors was carried out. Individually, the EMS domains Disconnection & Rejection, Impaired Autonomy & Performance, Impaired Limits, Other-directedness, and Overvigilance & Inhibition were positively associated with transdiagnostic depressive symptoms (rs .451, .365, .289, .298, .345, p < .001), as hypothesized. The joint effect of the five EMS domains was positively associated with transdiagnostic depressive symptoms (Adj. R2 = .18, F(7, 117) = 4.88, p <.001). Interestingly, when holding the other domains constant, only the Disconnection & Rejection domain significantly predicted transdiagnostic depressive symptoms in the model (β = .44, 95% CI [.15, .74], p = .004). The domain groups the beliefs about expectations that one’s needs for security and stability will not be met predictably. Our findings suggest that each EMS domain is positively related to transdiagnostic depressive symptom severity in a university student population. The Disconnection & Rejection domain, relative to the other four domains, seems to uniquely contribute to transdiagnostic depressive symptoms. Future research could test whether identifying and changing the EMSs someone has in psychotherapy could reduce their transdiagnostic depressive symptoms across different psychological disorders. It remains a question if paying specific attention to the Disconnection & Rejection domain in psychotherapeutic treatment could improve the reduction of transdiagnostic depressive symptoms.Show less
