The study investigated: (1) if there is an AB to or from itch; (2) whether this differs between people with chronic itch and healthy controls; (3) and if there is a possible AB/stress association. This is because understanding ABs to/from itch further elucidates the experience of patients with chronic itch and possible future clinical applications. Furthermore, an explorative analysis compared two tasks measuring AB, namely the Posner cueing and dot-probe task. The two tasks, alongside a stress-questionnaire, were administered online to the participants (N=70). A (frequentist and Bayesian) RM ANOVA was done for the main analysis, and a within- subjects t-test for the explorative task-comparison. Given that the task-comparison found the two tasks differing significantly (p = 0.01 d = -0.31), the results of the two tasks were interpreted separately. Overall, indications of AB being biased away from itch stimuli was found. When the AB was contrasted between participant group (people with and without chronic itch), the Posner cueing task found no significant difference (p = 0.68, ηp 2 = 0.003) whereas the dot-probe task found an AB away from itch-stimuli in patients with chronic itch (p = 0.02, ηp 2 = 0.077). Similar pattern unfolded with the stress-association: the Posner cueing task finding that AB did not significantly differ with stress (p = 0.23, ηp 2 = 0.021). The dot-probe task did find that they significantly differed (p = 0.01, ηp 2 = 0.091) where with higher stress, the AB switched to being an AB towards itch stimuli. The discrepancy between the two tasks aligns with expectations considering that the tasks were found inequivalent - highlighting one of the strengths of this study being that the two tasks were compared. Altogether this points towards differences in what the two tasks tap into, and that the attention of people with chronic itch is biased as a function of stress. Summarizing, AB to itch differed between the two groups and was associated with stress when using dot-probe task, which did not apply to the Posner cueing task.Show less

Data were collected using a scenario approach (N = 205) in an experimental study, which simulated a debt assistance setting in a municipality. The variables Status (low/high) and Warmth (low/high) were investigated in a betweensubjects design. Participants completed an online survey on perceived warmth, status, and locus of attribution of a help-seeker and indicated their willingness to help as well as the type of help. It was hypothesized that warmth perceptions of help-seekers would influence the likeliness to help, that status perceptions would influence the locus of attributions as well as the type of help and that the effect between status and type of help would be mediated by the locus of attributions. The study did not find support for these hypotheses. However, exploratory analyses revealed a significant positive effect of both Status and Warmth on perceived competence, and significant correlations between locus of attributions and likeliness to help, autonomy and dependency-oriented help, and emotions (admiration/envy/pity) and type of help. These findings underline the role of stereotypes and biases in influencing helping behavior, emphasizing the need for further investigations of helping mechanisms.Show less

However, it is uncertain if the ability to learn sequences of movements is also impaired in this population. Therefore, this study investigated whether aMCI and AD affect motor sequence learning abilities, and how such abilities are related to AD biomarkers. The sample included 33 individuals with aMCI, 28 with AD, and 52 healthy controls (HCs). All groups completed a motor task consisting of performing a sequence of button presses, alternated with random blocks. Reaction time, coefficient of variation, and learning rates were obtained from the task. Participants also completed a series of cognitive tests to assess memory, visuospatial abilities, processing speed, language, and attention. Additionally, the following biomarkers for AD were assessed: amyloid beta via PET imaging, hippocampal volume via structural MRI, and number of e4 alleles via APOE genotyping. ANOVAs showed that AD participants had longer and more variable reaction times, followed by aMCI individuals, and with HCs having the shorter and more consistent reaction times. No significant differences in sequence learning rate were observed between groups. Exploratory analyses revealed that aMCI/AD had significantly slower initial learning rate than HCs. Linear regressions showed associations of slower reaction times with smaller hippocampal volume, and of higher coefficients with higher amyloid deposition. Poisson regressions revealed no significant correlations between motor sequence learning and APOEe4 allele count. Akaike Information Criterion (AIC) results indicated that combining cognitive test with motor measures improves the prediction of AD biomarkers. Overall, AD and aMCI individuals showed impairments in general motor performance but relatively preserved motor sequence learning abilities, with some deficits in initial rate of learning. Moreover, statistical model comparison suggested that adding motor sequence learning measures to neuropsychological assessment tools enhanced the prediction of AD biomarkers. As such, future studies should explore the value of integrating motor sequence learning measures in the assessment and tracking of AD/aMCI.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

The contribution of this paper is two-fold. First, it gave an extensive overview of relevant research from numerous fields, which were subsequently combined into one overarching theoretical framework. Secondly, a preliminary empirical analysis was conducted using multiple linear regression (OLS) models to test the resulting expectations - that horizontal inequalities (economic and political) are likely positively related to civilian victimisation during civil wars. The analysis came back with mixed results, and at best limited and indirect support for the expected positive link between horizontal inequality and civilian victimisation.Show less

Analyzing the Dutch submarine order and Rheinmetall's industrial expansion into Ukraine, it explores the interplay between government policies, corporate interests, and international security. Utilizing realism and corporatism, the study highlights how states and industries navigate defense procurement to achieve national security and economic goals. Realism emphasizes state interests and competition, which is utilized by the military-industrial complex to their advantage. Corporatism focuses on collaborative interactions between government and industry which can be used by governments to get the best offer. The findings reveal that defense procurement is influenced by government priorities, key players, corporate strategies, and lobbying. Overall, this research provides insights into the military-industrial complex's role in shaping EU defense policies and international relations.Show less

People all around the world are engaging in environmental activism, yet environmentalism research has disproportionately centered on the West. Considering how most countries on the front lines of climate change are non-Western, this gap must be rectified. Southeast Asia (SEA) is a region severely overlooked in this regard, particularly in terms of what environmentalism actually brings here. There is insufficient knowledge on how SEA states respond to environmental activism, despite the relevance for its citizens and environmental sector practitioners, who witness some of the worst repercussions of environmental degradation. Therefore, this paper aims to expand our understanding of state responses to SEA environmentalism and contentious political action by investigating Vietnam and the Philippines. A comparative study was conducted on these two cases, which employed qualitative content analysis on texts like news articles to study responses to environmentalism. Findings reveal that both countries display a variety of responses, but are most inclined to repress. However, they differ considerably in how they approach each response type in terms of methods, actors involved, and consistency. It is proposed that each country’s distinct response pattern is linked to its respective regime type, as suggested by existing literature on contentious political action. Beyond the popular notion that non-democracies are more likely to repress contentious claim-making, this study illustrates how hybrid regimes can be more covert and lethal in their repression than other regimes. From these findings, this paper stresses the importance of local socio-political contexts for those engaged in environmental protection and advocacy. Additionally, this investigation hopes to spur similar research on other SEA countries and expand the political science literature on this region.Show less

The involvement of Iranian diaspora communities in cyberspace successfully transformed this movement into the online sphere. This paper seeks to answer the following research questions: How do Iranian diaspora communities construct identity through cyberfeminism in the 'Women, Life, Freedom' movement? The paper aims to explore the effectiveness of cyberfeminism and more importantly, it aims to identity the role of X and diasporic websites in constructing Iranian diaspora’s identity through an inductive approach. Frame theory is utilized as a lens to examine how Iranian diasporas frame themselves in the cyberspace and make connections between those inside and outside Iran. This paper finds three framing strategies, namely: identification of common enemies, victimization, and empowerment of women that contribute to forming a collective identity within diasporas.Show less
