Why Do Bystanders Report Intimate Partner Violence? Insights into Real-Life Reasoning from Those Who Actually Intervened.

As intimate partner violence (IPV) often remains unknown to police, bystanders can play a crucial role in prevention and further escalation of IPV. However, little is known about what brings them into action by reporting incidents of IPV to authorities. As such, we use statements of bystanders who filed reports about IPV incidents to an official domestic violence agency in the Netherlands ( = 78), to investigate the reasoning and motivations for reporting their suspicions.

Protocol of a monocentric, double-blind, randomized, superiority, controlled trial evaluating the effect of in-prison OROS-methylphenidate vs. placebo treatment in detained people with attention-deficit hyperactivity disorder (BATIR).

Background: Attention-deficit hyperactivity disorder (ADHD) is characterized by difficulty paying attention, poor impulse control, and hyperactive behavior. It is associated with several adverse health and social outcomes and leads to an increased risk of criminality and recidivism. Worldwide, ADHD is thus highly prevalent in prisons.

Who's Keeping an Eye on the Kids? Changes in Monitoring During Emerging Adulthood.

Previous research indicates that parental monitoring protects adolescents from delinquency. While, emerging adults spend increasing amounts of time outside the family setting, they often remain in or return to reside in the parental home, possibly prolonging the period of parental monitoring. We examine whether parental monitoring, differentiating between child disclosure, parental solicitation, and parental control, is a protective factor for delinquency for emerging adults.

More Than Just a Scratch: A Scoping Review on Physical and Psychological Consequences of Violence Against Police.

Violence against police is a reality for many officers. Despite growing concerns over the rise in violence against police and the serious individual and societal repercussions associated with it, a comprehensive overview of the psychological and physical consequences of verbal and physical violence against police remains elusive. By performing a scoping review ( = 21) of studies and reports identified via database searches (Web of Science and Google Scholar), reference mining, and purposive sampling, and published between 2010 and 2023, this article is the first of its kind to map psychological and physical consequences of violence against police, as well as the risk and protective factors that respectively increase and decrease adverse consequences.

The interpretation of forensic conclusions by professionals and students: Does experience matter?

Are professionals better at assessing the evidential strength of different types of forensic conclusions compared to students? In an online questionnaire 96 crime investigation and law students, and 269 crime investigation and legal professionals assessed three fingerprint examination reports. All reports were similar, except for the conclusion part which was stated in a categorical (CAT), verbal likelihood ratio (VLR) or numerical likelihood ratio (NLR) conclusion with high or low evidential strength. The results showed no significant difference between the groups of students and professionals in their assessment of the conclusions.

Why do we never have enough time? Economic inequality fuels the perception of time poverty by aggravating status anxiety.

People in many societies report that they do not have enough time. What makes people feel so rushed? We propose that economic inequality leads to perceived time poverty by increasing status anxiety. Five studies examined this line of reasoning.

Direct and Indirect Genetic Effects on Aggression.

Background: Family members resemble each other in their propensity for aggression. In twin studies, approximately 50% of the variance in aggression can be explained by genetic influences. However, if there are genotype-environment correlation mechanisms, such as environmental manifestations of parental and sibling genotypes, genetic influences may partly reflect environmental influences.

How does economic inequality shape conspiracy theories? Empirical evidence from China.

Conspiracy theories tend to be prevalent, particularly in societies with high economic inequality. However, few studies have examined the relationship between economic inequality and belief in conspiracy theories. We propose that economic inequality leads people to believe conspiracy theories about economically advantaged groups (i.

The Co-Twin Control Design: Implementation and Methodological Considerations.

Establishing causal relationships in observational studies is an important step in research and policy decision making. The association between an exposure and an outcome can be confounded by multiple factors, often making it hard to draw causal conclusions. The co-twin control design (CTCD) is a powerful approach that allows for the investigation of causal effects while controlling for genetic and shared environmental confounding factors.

Genetics and epigenetics of human aggression.

There is substantial variation between humans in aggressive behavior, with its biological etiology and molecular genetic basis mostly unknown. This review chapter offers an overview of genomic and omics studies revealing the genetic contribution to aggression and first insights into associations with epigenetic and other omics (e.g.

Parental Divorce and Adolescent Offending: A Comparison Between Children of Discordant Siblings.

Various studies have found that parental divorce is associated with offspring offending during adolescence. Less is known, however, about the mechanisms underlying this association, and it may be possible that this association is spurious rather than causal. In this study, register data on 1,883,794 individuals, who were born in the Netherlands between 1991 and 2001, and their parents were used to examine to what extent parental divorce is associated with offspring adolescent offending.

Changing perspectives: enhancing learning efficacy with the after-action review in virtual reality training for police.

The After-Action Review (AAR) in Virtual Reality (VR) training for police provides new opportunities to enhance learning. We investigated whether perspectives (bird's eye & police officer, bird's eye & suspect, bird's eye) and line of fire displayed in the AAR impacted the officers' learning efficacy. A 3 x 2 ANOVA revealed a significant main effect of AAR perspectives.

The mechanism of assortative mating for educational attainment: a study of Finnish and Dutch twins and their spouses.

Assortative mating refers describes a phenomenon in which individuals with similar phenotypic traits are more likely to mate and reproduce with each other; i.e. assortative mating occurs when individuals choose partners based on their similarity or dissimilarity in certain traits.

Just Dead, Not Alive: Reconsidering Belief in Contradictory Conspiracy Theories.

A well-established finding is that beliefs in contradictory conspiracy theories (e.g., Princess Diana was murdered vs.

Punishing Atrocity Crimes in Transitional Contexts: Advancing Discussions on Adequacy of Alternative Criminal Sanctions Using the Case of Colombia.

Criminal trials and proportional prison sentences are generally seen as the most suitable way to deal with perpetrators of atrocity crimes. Notwithstanding, traditionally conceived criminal penalties, such as imprisonment, may discourage active responsibility-taking by offenders, disaffect victims by not meeting their needs and impede meaningful engagement between perpetrators and survivors. Arguably, alternative criminal sanctions may be appropriate punishment even for atrocity crimes when tried in transitional societies.

Online Communities for Child-Attracted Persons as Informal Mental Health Care: Exploring Self-Reported Wellbeing Outcomes.

Online support communities are gaining attention among child-attracted persons (CAPs). Though research has largely focused on the negative consequences these environments create for potential offending, they may also provide a beneficial alternative to more formal treatment settings. To assess the utility for clinical and therapeutic purposes, this analysis focused on subcultural dynamics to examine self-reported wellbeing outcomes of participation in a Dutch forum for CAPs.

"Sometimes It Seems Easier to Push It Away": A Study Into the Barriers to Help-Seeking for Victims of Sexual Violence.

Experiencing sexual violence may have serious long-term consequences for victims. Seeking help may decrease the chances of developing long-term physical and psychosocial problems. Still not every victim seeks help, and especially with victimization of sexual violence, there may be several reasons as to why.

'Birds of a feather' - forever? Homogeneity in adult friendship networks through the life course.

This paper studies the changes in the homogeneity of friendship networks in terms of gender, age, and educational diversity. It is argued that through the life course, both an individual's demand and the structural supply of similar others change. This should be reflected in the composition of friendship relations in personal networks.

No pain, no gain? The effects of adding a pain stimulus in virtual training for police officers.

Virtual training systems provide highly realistic training environments for police. This study assesses whether a pain stimulus can enhance the training responses and sense of the presence of these systems. Police officers ( = 219) were trained either with or without a pain stimulus in a 2D simulator (VirTra V-300) and a 3D virtual reality (VR) system.

Stay Home, Stay Safe? The Impact of the COVID-19 Restrictions on the Prevalence, Nature, and Type of Reporter of Domestic Violence in the Netherlands.

Purpose: Insecurities and social isolation resulting from the COVID-19 restrictions, may have elevated tensions at home, consequently increasing the risk of domestic violence. The present study aims to examine changes in the prevalence, nature, and type of reporter of domestic violence following the various restrictions implemented to control the spread of the COVID-19 virus in the Netherlands.

Methods: All official domestic violence reports recorded by the 26 Dutch domestic violence agencies in 2019 and 2020 were collected and analyzed.

Decision-making by and for adults with impaired capacity: The potential of the Dutch levenstestament.

Anticipatory decision-making instruments - continuing powers of attorney and advance directives - are increasingly seen as a promising way forward to enhance the autonomy of adults with impaired capacity by making the adult's voice an influential component of future decisions. However, little is known about the experiences with these instruments in practice. This article presents the findings of an interview study looking at the expectations and experiences of both adults and attorneys with a Dutch anticipatory decision-making instrument, the so-called levenstestament.

Understanding Changes in Violent Extremist Attitudes During the Transition to Early Adulthood.

Objectives: The current study seeks to explain changes in support for violent extremism during the transition to early adulthood. This period during the life course could increase uncertainty and vulnerability to radicalization, or alternatively lead to maturation, prosocial bonds, and consequently less support for violent extremism. In the absence of population-based longitudinal data on violent extremist attitudes, we know very little about how and why attitudes change during this period.

Brief report: Free-living physical activity levels and cognitive control in multi-problem young adults.

Previous studies indicate a positive association between physical activity and cognitive control in sedentary but healthy adults, yet not much is known about physical activity levels in multi-problem young adults. We examined the level of self-reported free-living physical activity (i.e.

Detainees' Perceptions of Procedural Justice: An Examination Throughout the Criminal Justice System.

Procedural justice literature proposes that when individuals perceive their treatment by criminal justice authorities as more procedurally just, they will be more likely to view those authorities as legitimate and, in turn, show more compliant behavior. Knowledge on potential determinants of procedural justice is, therefore, crucial. Research suggests that prior perceptions of procedural justice may influence later judgements of procedural justice.

Corrupt third parties undermine trust and prosocial behaviour between people.

Corruption is a pervasive phenomenon that affects the quality of institutions, undermines economic growth and exacerbates inequalities around the globe. Here we tested whether perceiving representatives of institutions as corrupt undermines trust and subsequent prosocial behaviour among strangers. We developed an experimental game paradigm modelling representatives as third-party punishers to manipulate or assess corruption and examine its relationship with trust and prosociality (trust behaviour, cooperation and generosity).
