Show moreAmple research has shown that more household chaos is related to lower parenting quality, but it is yet unknown whether this is a causal relation. This dissertation focuses on two research questions. The first is whether household chaos has a causal effect on parenting. The second is whether the effect of household chaos on parenting is stronger for parents with certain characteristics, such as high sensory-processing sensitivity (SPS), low self-regulation, and more impulsivity. Two experimental studies were conducted in which household chaos was manipulated. The results show that household chaos affects both positive and negative parenting, but only in demanding parenting situations. Moderation by impulsivity was not found and moderation by SPS and by self-regulation was inconsistent. Regarding SPS, this may exacerbate the effect of household chaos on parenting in case of extreme differences between or high levels of household chaos. Regarding self-regulation, parents with low self-regulation may not have enough self-regulation capacities to simultaneously lower their levels of household chaos and refrain from harsh discipline. These results form a promising vantagepoint for further research, which could eventually lead to prevention and intervention programs to improve parenting by reducing household chaos. Show less

Show moreThe present study employs a randomized control trial design to evaluate the impact of deterrence and procedural justice on perceptions of legitimacy and cooperation with law enforcement among individuals in Quito, Ecuador. Specifically, a sample of 308 premises where alcohol is sold were randomly assigned to one of two conditions: an experimental group (n = 156) in which officers received training in the implementation of a procedural justice-based script, and a control group (n = 152) in which officers were not provided with any specific instructions. Results indicate that the manipulation of procedural justice was associated with a significant enhancement in perceptions of legitimacy and a greater willingness to cooperate with the police.

Show moreThe current study investigates whether self-talk phrases can infuence behavior in Ultimatum Games. In our three self-talk treatments, participants were instructed to tell themselves (i) to keep their own interests in mind, (ii) to also think of the other person, or (iii) to take some time to contemplate their decision. We investigate how such so-called experimenter-determined strategic self-talk phrases afect behavior and emotions in comparison to a control treatment without instructed self-talk. The results demonstrate that other-focused self-talk can nudge proposers towards fair behavior, as ofers were higher in this group than in the other conditions. For responders, self-talk tended to increase acceptance rates of unfair ofers as compared to the condition without self-talk. This efect is signifcant for both other-focused and contemplation-inducing self-talk but not for self-focused self-talk. In the selffocused condition, responders were most dissatisfed with unfair ofers. These fndings suggest that use of self-talk can increase acceptance rates in responders, and that focusing on personal interests can undermine this efect as it negatively impacts the responders’ emotional experience. In sum, our study shows that strategic selftalk interventions can be used to afect behavior in bargaining situations. Show less

Show moreWhy can vigilantes count on public support? Why do citizens in certain cases oppose the formal prosecution and punishment of vigilantes? Are such reactions an indication of lacking confidence in the criminal justice system? Or do situational aspects perhaps also play a role? The goal of this dissertation is to explain public support for vigilantism. In two studies, respondents were presented with a fictional case about vigilantism and answered related questions. The findings of both studies show that support for vigilantism cannot be interpreted automatically as a sign that confidence in the criminal justice system is lacking: situational characteristics have an independent influence on support. The results also reveal that support for vigilantism is a complex concept. People are not simply for or against vigilantism; responses to vigilantism are more nuanced. People can for instance feel little empathy for the victim of vigilantism, but at the same time express a desire for punishment of the vigilante. Additionally, a higher level of confidence in the courts and criminal justice system led to less support for vigilantism, while confidence in police did not play a role. Lastly, general support for vigilantism was an important predictor of support for a specific case. Show less

Show moreThe relationship between the media and politics is close and often characterized by tensions. Politicians often are accused of being led by short-lived media cycles in their actions, thereby losing sight of broader societal interests. At the same time, the media are accused of primarily seeking out conflicts and sensational news which is detrimental to both politics and society. This dissertation provides an empirical test of these claims based on unique data from experimental studies with elected politicians and political journalists in Switzerland and the Netherlands. What media reports trigger politicians to take parliamentary action? And how and when do messages from political parties get picked up by journalists? The answers to these two questions presented in the first part of the book provide the basis for a unique direct comparison of the selection mechanisms politicians and journalists apply in the final part.

Does the way in which governments respond to disasters affect their legitimacy? The current study investigated how evaluations of authorities were influenced by four aspects of a governmental response to a hypothetical disaster. In a survey experiment participants read a scenario in which a government distributed aid in the aftermath of a flooding. Data were collected from the Netherlands, France, Poland, Ukraine, and Russia (N = 2,677). Results showed that the government was seen as more legitimate when it was described as distributing resources fairly, following fair procedures, and providing a material benefit to the participant. However, in contrast to predictions derived from system‐justification theory, results showed that outcome dependence was associated with reduced legitimacy. These findings suggest that response policies that address both instrumental and fairness concerns might help maintain positive evaluations of governments. Show less

Show moreAs the de facto industry standard for software modeling, the Unified Modeling Language (UML) is used widely across various IT domains. UML__s wide acceptance is partly because the language offers flexibility and freedom in modeling software systems: 1) UML provides an extensive set of modeling notations that can be used to model various concepts; 2) UML can be used both in a casual and formal manners. In the context of model-driven software development, the degree of freedom in which UML is used raises an important issue related to model quality. Different styles and rigors in using UML affect the quality of the resulting models. It is then logical to think that the level of quality of the UML model may affect the quality of the resulting software. This thesis reports on a series of empirical studies performed to address a pivotal question concerning the benefits of UML modeling in software development, particularly from a quality perspective. The results of these empirical studies show that the use of UML provides benefits in terms of increased quality and productivity in software development. The availability of UML models also allows early prediction of defects in software systems. Such prediction is potentially useful for identifying and fixing defects early during software development, and for prioritizing testing. Show less

Show moreLaws regulate behaviour. However, human beings do not always obey the law. This makes it important to identify how law enforcement can stimulate compliance. This thesis investigates multiple gaps in the literature on instrumental and normative pathways to compliance and counters some of the limitations in previous research. It contains three empirical studies that answer the following questions. Do citizens update their perceived sanction risk in response to changes in police activity? Does police behaviour that signals higher quality of treatment or decision-making lead to higher perceived procedural justice? Howdo instrumental and normative motivations translate into greater compliance with traffic laws?All results are based on field research conducted with the help of the Dutch National Police between January and August 2017. During this period data was collected at routine traffic control check-points for mopeds. The combination of data gathered through surveys, structured social observations and an experimental manipulation contributes to a better and more precise understanding of pathways to compliance.
