PDW involves tasks during work that require prolonged standing, heavy lifting, repetitive movements, and taxing postures. Recent research shows that PDW deteriorates health, but mechanisms and buffers or boosters for this relation have remained unclear. In the present study, lower leisure-time physical activity (LTPA) and higher alcohol consumption are postulated as explanations and as moderators for the negative relation between PDW and health. Thus, this study investigates the relationship between PDW and health outcomes over one year, and further focusses on the potential mediating and moderating roles of the lifestyle behaviors, LTPA and alcohol consumption. The sample consisted of N = 1,259 Dutch employees and data was used from a longitudinal study (LISS-panel) conducted over two waves with a one-year interval (2021-2022). Using self-reported questionnaires, the participants reported about their health status (at both baseline and after one year), physical work demands, alcohol consumption and participation in LTPA. The statistical analysis involved a regression analysis (main effect), and the PROCESS Macro by Hayes model 1 (moderation) and 4 (mediation). There was controlled for gender, age, education level and health at baseline. The analyses showed that first, in line with the literature, PDW negatively affects health. Second, neither LTPA nor alcohol consumption significantly mediates or moderates the negative relationship between PDW and health outcome. These results suggest that the impact of PDW cannot be explained by the lifestyle factors studied. Also, the findings point at a need for investigating other mechanisms in the relation between PDW and health, such as other lifestyle behaviors or implementing tools to make jobs itself less physically demanding. We also recommend future research to follow up on these findings with objective measurements of health and physical activity (instead of self-reporting questionnaires), longer study periods, and the use of multiple item questions to fully understand the long-term health implications of PDW and lifestyle behavior.Show less

The European Union plays a leading role in climate politics and the global reduction of greenhouse gas emissions through one of its key tools, the Emissions Trading System. This thesis examines the impact of EU member states’ industrial composition on implementing the EU ETS in phase 2 through a comparative analysis of the Netherlands and Belgium. An examination of the correlation between national industries and the national implementation of the ETS has thus far remained absent in the existing literature and provides policy insights for future climate politics. An analysis of the relevant policy documents reveals how both countries varied in their implementation of the system. It demonstrates how the more pollutive industrial composition of the Netherlands caused the government to be more responsive to the affected industries’ interests in the allocation process. However, contrary to expectations, the Netherlands was not more lenient the monitoring of the system and was even more strict than Belgium in most areas.Show less

Dit onderzoek kijkt als een van de eerste onderzoeken naar descriptieve representatie als afhankelijke variabele. Hiermee wordt een wetenschappelijke bijdrage geleverd door te onderzoeken welke factoren een invloed hebben op de mate van descriptieve representatie. In dit onderzoek worden regressieanalyses gebruikt om te onderzoeken of er een correlatie bestaat tussen descriptieve representatie van vrouwen, mensen met een migratieachtergrond en leeftijd als afhankelijke variabelen. Daarnaast gaat het in dit onderzoek om het aandeel hoogopgeleiden, gemiddeld inkomen per persoon en de mate van religieuze aanhang in een gemeente als onafhankelijke variabele. Er wordt geconcludeerd dat opleidingsniveau een positief verband kent met descriptieve representatie. Gemiddeld inkomen kent een negatief verband bij descriptieve representatie van vrouwen en voor mensen van de leeftijd van 18 tot en met 35 jaar. De mate van religieuze aanhang heeft een negatief effect op de descriptieve representatie van vrouwen. Voor migratieachtergrond en leeftijd zijn er in dit onderzoek geen statistisch significante verbanden gevonden.Show less

De studie is uitgevoerd middels semi-gestructureerde interviews en is kwalitatief van aard. Er is voor een kwalitatieve benadering gekozen omdat op deze manier diepere kennis vergaard kan worden. Daarnaast is gekozen voor een selecte steekproef, waarbij alleen de cliënten van Siriz zijn geworven op vrijwillige basis. De uiteindelijke steekproef bestond uit twee personen. De data zijn geanalyseerd door middel van een inhoudsanalyse om te kunnen achterhalen wat de uitdagingen en behoeften van de ongeplande zwangere vrouwen zijn. Tevens is een literatuuronderzoek uitgevoerd. Uit de literatuur blijkt dat ongeplande zwangerschappen gepaard kunnen gaan met fysieke problemen en een negatievere kijk op hun zwangerschap en bevalling dan vrouwen met een geplande zwangerschap (Karaçam et al., 2011). Echter was er beperkte beschikbare literatuur. De gevonden informatie sluit hierdoor niet volledig aan op de onderzoeksvraag. Het empirisch onderzoek toonde aan dat de deelnemers vooral uitdagingen ervaren op het gebied van gebrekkig contact met eigen opvoeders, financiën, sociale vaardigheden en beide deelnemers hebben geen relatie meer met de biologische vader van hun kinderen. Daarnaast blijkt uit het onderzoek dat de behoeften verschilden per individu. De deelnemers gaven aan behoefte te hebben aan meer duidelijkheid en ondersteuning na de bevalling, aan meer lichaamsbeweging en om te stoppen met roken. Tevens gaven ze aan behoefte te hebben aan opvang of een oppas voor hun kind om werk of studie te kunnen combineren met de verzorging van het kind. Tot slot was er behoefte aan oude leefgewoonten. Om de vrouwen binnen Siriz optimaal te kunnen helpen, is het van belang dat er naar gestreefd wordt om elke ongepland zwangere vrouw de juiste hulp en ondersteuning te bieden bij haar specifieke situatie. Maatwerk is daarom een cruciaal aspect. De ondersteuning kan geboden worden middels voorlichting, trainingen of intensieve een-op-een begeleiding. Geadviseerd wordt dat Siriz zich gaat richten op het bieden van gerichte ondersteuning op de veelvoorkomende uitdagingen en behoeften die in dit onderzoek naar voren zijn gekomen. Dit kan ervoor zorgen dat de ongepland zwangere vrouwen zich beter kunnen redden in het dagelijks leven. Door het bieden van ondersteuning kan de zelfredzaamheid en het psychosociaal functioneren verbeterd worden.Show less

To minimize the negative effects of climate change, it is important to increase our pro-environmental behavior. This study explored the underlying factors within the environmental attitude – behavior gap among young adults by investigating the mediating role of descriptive environmental norms between environmental attitudes and pro-environmental behavior of young adults, moderated by social connectedness. Data was collected from 216 young adults using self-report questionnaires. The moderated mediation model using Hayes PROCESS macro (model 14) was conducted to test the study hypothesis. Results showed there was no significant moderated mediation. Environmental attitudes were not significantly associated with either pro-environmental behavior or descriptive environmental norms. However, descriptive environmental norms showed a significant positive association with pro-environmental behavior (t = 6.86, p < .001, 95% CI [0.27, 0.49]). Furthermore, social connectedness significantly moderated the association between descriptive environmental norms and pro-environmental behavior, with lower social connectedness strengthening this association (t = -2.39, p = .018, 95% CI [-0.23, 0.02]). These findings provide a better understanding of what drives young adults to pro-environmental behavior and can contribute to more targeted campaigns to encourage young adults to pro-environmental behavior.Show less

Research has shown that both maternal and child characteristics can significantly impact the stability and length of these out-of-home placements, yet there is a lack of comprehensive studies examining these relationships within the Dutch context. Understanding these factors is crucial for developing effective interventions and support mechanisms. That is why this study aims to investigate the associations between the duration of out-of-home placements and maternal and child risk factors, as well as the role of help provided during the placement. Method: A case file analysis was conducted of 199 children (104 boys, 95 girls) within the Dutch child welfare system. The data was collected from randomly selected case files from various certified agencies across the Netherlands. The study employes both correlation and regression analysis to examine the relationship between the variables. Results: Correlation analysis revealed a significant negative correlation between maternal risk factors and the child’s age and a significant positive correlation with the duration of the placement and the amount of help provided during the placement. Child risk factors were positively correlated with the child’s age and negatively correlated with maternal risk factors. Regression analysis confirmed that maternal risk factors and help during the placement are significant predictors of the duration of out-of-home placements. Conclusions: This study underscores the importance of targeted interventions addressing maternal risk factors and providing psycho-education for mothers regarding their role in the duration of out-of-home placements. Additionally, it is crucial to ensure that access to support services is easy and straightforward for mothers, to encourage their engagement and participation in available interventions.Show less

Therefore, this study aimed to further demonstrate whether differences in perceptions of inequality of opportunity and outcome negatively affects students’ educational aspirations. Further, based on previous research demonstrating positive main effect of internal locus of control (Sagone & Caroli, 2014) and a moderating effect of internal locus of control (Jia et al., 2021) on educational outcomes, locus of control was added as a moderator to see if an internal locus of control offsets negative effects of inequality on educational aspirations. Our manipulation, videos explaining inequality of opportunity and outcome, failed to tease apart perceptions of inequality of opportunity and outcome and were consequently combined into one factor, inequality. We found no significant main effect of perception of inequality, but a significant positive main effect of locus of control on educational aspirations. An interaction effect between perceptions of inequality and locus of control on educational aspirations was found. However, unexpectedly, students perceiving inequality within the external locus of control group scored highest on educational aspirations. Implications, limitations, and avenues for further research are discussed.Show less

Research indicates that students tend to have poorer diets during exam periods, with stress and sleep quality potentially influencing this pattern. The decline in diet quality among university students during examinations is a significant social issue that needs to further understanding. The aim of this study was to assess the relationship between exam stress and perceived changes in food choice -healthy or unhealthy eating- during an exam period among university students aged 18 to 25 and to assess to what extent this relationship is mediated by sleep quality during an exam period. Utilizing a cross-sectional design, data was collected from 200 Dutch university students who completed three questionnaires, the Examination Stress Scale, a questionnaire about changes in food choice during an exam period and the Regensburg Insomnia Scale. A mediation analysis was conducted using linear regressions in SPSS. The results indicated no significant relationship between exam stress and changes in food choice (β = .042 , p = .558). There was a significant positive relationship between exam stress and poor sleep quality (β = .44, p < .001). No significant association was found between sleep quality and changes in food choice (β = -.02, p < .770). When controlling for sleep quality, exam stress was still not associated with changes in food choices (β = .05, p < .514). Thus, the present study concluded that there is no relationship between exam stress and perceived changes in food choice -healthy or unhealthy eating- among university students ages 18 to 25 and that this relationship is not mediated by sleep quality during exams. However, there was a significant relationship between exam stress and poor sleep quality. Prevention strategies for exam stress and poor sleep should include stress management and education about the importance of sufficient sleep.Show less

Remaining open to alternative explanations, through exploring discourse of Afro-Brazilian movement Black Coalition for Rights, this study concludes that two forms of consciousness theoretically assumed to be different are both built on similar premises that recognise the role of capitalist structures in processes of racialisation.Show less

Symptoms of stress are a commonality of these disorders. However, the role of this commonality in the co-occurrence remains unknown. This cross-sectional study investigated the co-occurrence of depression, anxiety, and stress in adolescence using the network psychometrics approach. We obtained our data from the Open-Source Psychometrics Project. The data consisted of the Depression Anxiety Stress Scale (DASS)-42 (N = 25,086, ages 13-24 years old). We estimated Gaussian Graphical Models (i.e., partial correlations between nodes) and analyzed the bridge nodes. Bridge nodes are nodes of the network that are most influential in connecting the different disorders. We expected the bridge nodes to be the overlapping symptoms found among depression, anxiety, and stress as indicated in the DSM-V. Moreover, to examine whether bridge nodes were consistent across adolescence, we divided our sample into three age groups: early adolescence (ages 13-15, N = 2,354), middle adolescence (ages 16-19, N = 9,476) and late adolescence (ages 20-24, N = 13,256). Our findings of the full sample adolescent network indicated that symptoms of restlessness (stress) and negative mood (depression) served as bridge nodes, which was in line with our hypothesis. Other bridge nodes, not in line with our hypothesis, were symptoms of subjective experience of anxiety (anxiety) and situational anxiety (anxiety). Bridge nodes exclusive to the late adolescent network were: Finding it hard to wind down (stress) and feeling terrified (anxiety). Moreover, relief after anxious situations (anxiety) was uniquely present in the early and late adolescent networks. This study expands the current theoretical knowledge by, for the first time to our knowledge, including stress symptoms in the network models and by comparing the different adolescent age groups using a broad age range (13 to 24 years). Future research should examine whether clinicians can successfully incorporate this knowledge into transdiagnostic treatment interventions, which could contribute to better overall mental health.Show less

It has been recognized recently that vascular risk factors (VRF), such as hypertension, diabetes, and hyperlipidemia, can also have detrimental effects on these cognitive domains. Less research has been conducted on the synergistic influence of MCI and VRF on cognition, with available studies providing mixed results. Moreover, only one study has been conducted on the topic regarding the Greek population, so more research is needed to account for possible differences in ethnicity-related variables. Therefore, we sought to investigate how MCI with comorbid VRF influence PEM and EF, compared to VRF alone and healthy ageing. A sample of 111 Greek older adults participated in the study, divided into three groups: patients with MCI and concomitant VRF, patients with VRF and healthy controls. To assess cognition, tests were used to measure PEM, interference control, flexibility and semantic and phonemic verbal fluency. Data were analysed using MANCOVA, controlling for the educational level of the participants. Results showed that there were no differences between the two pathological groups for any of the measures, but the healthy controls outperformed the MCI+VRF (adjusted mean difference of total score being 8.94, 95 % confidence interval (CI) [3.67, 14.20], p < .001) and the VRF group (adjusted mean difference of total score being 8.20, 95% CI [2.94, 13.46], p < .001) in the semantic fluency task. Indeed, literature has shown that both MCI and VRF affect the integrity of frontal networks, which mainly support EF function. Methodological differences, such as the older age of the sample and the simplicity of the PEM task, ethnic differences and limitations in the statistical analysis can possibly account for the discrepancies with previous studies. All in all, this study suggests that there are no differences in cognition between VRF and MCI+VRF patients, while emphasizing the need for and more research into the cognitive consequences of comorbid MCI and VRF both in the Greek population and internationally.Show less

Differences in literary skills exist and increase at early ages. It is important to close the gap early so that every child gets an equal opportunity to develop their literary skills. This research evaluates the effectiveness of digital readingaloud programs aimed at developing early literary skills, such as broad and deep vocabulary which form the basis for later reading comprehension. The role of active attention is studied, as differences in active attention during the reading-aloud programs might cause differences in effectiveness of the program on developing reading skills. Different reading-aloud programs are used in pre-school classrooms (groups 1 and 2 in the Dutch education system) during several weeks. A total of 88 toddlers, of which 53 girls, have participated. Participants’ levels of broad and deep vocabulary are measured prior to following the programs and each time after following one of the programs. Active attention is measured using observations. Results indicated a strong effect for the development of broad vocabulary over the programs, where a program with instructions focused on semantics had the strongest effects. Students with higher degrees of active attention showed greater increases in broad vocabulary. Deep vocabulary develops to a lesser extent and additional instructions from the teacher did not show stronger effects. Toddlers with different degrees of active attention seemed to develop their deep vocabulary similarly. Active attention might play a smaller role in the development of broad and deep vocabulary than previously thought. Follow-up research should be aimed at the development of programs that are effective for every child, especially for those at risk of falling behind.Show less
