Negative Life Events and Epigenetic Ageing: A Study in the Netherlands Twin Register.

We aimed to understand the long-term impact of negative life events on epigenetic aging in 1783 adults from the Netherlands Twin Register, analyzing five epigenetic biomarkers (Hannum, Horvath, PhenoAge, GrimAge, DunedinPACE) and a series of negative life events, including victimization and economic hardship. In population-level analyses, associations between a higher number of negative life events (particularly financial adversities, sexual crimes, and job loss) were seen for the GrimAge biomarker. The association between the number of negative life events and financial problems and epigenetic age acceleration measured by the GrimAge biomarker persisted after adjusting for BMI, smoking, and white blood cell counts.

Delusion-proneness predicts COVID-19 vaccination behavior.

Introduction: Vaccination-related conspiracy ideation is related to reduced compliance with public health advice globally. Such beliefs have previously been linked to the delusion-proneness trait. However, it is not known how this extends to getting vaccinated.

A Comparative Study of the Help-Seeking Behavior of Victims of Contact Sexual Violence and Image-Based Sexual Harassment and Abuse.

Sexual victimization may have serious consequences for victims' well-being. Thus, seeking support is encouraged and associated with positive outcomes. However, no research has compared the help-seeking behavior of victims of contact and image-based (i.

Changes in Probation Officer Procedural Justice and Self-Reported Recidivism.

An increasing number of studies has studied the role of procedural justice for reducing recidivism in the probation context. The objective of this study is to contribute to existing knowledge by examining (a) whether people on probation alter their perceptions of probation officer procedural justice over time and (b) the extent to which changes in procedural justice relate to recidivism. This study utilized longitudinal data from 326 adults who were released from Dutch (pre-trial) detention centers and who had contact with the Probation Service.

Bystander Action Beyond Intervention: Video-Observing the Bystander Behavior of Men and Women in Real-Life Public Conflicts.

Previous research suggests that bystanders of conflicts use a range of intervention strategies. Yet, much less is known about other actions-beyond intervention-that bystanders might engage in during conflicts. Further, while prior studies reveal that gender differences emerge in bystander behavior, few studies have assessed the ecological validity of such potential differences in bystander actions during real-life conflicts.

System-justifying beliefs buffer against psychological distress during the COVID-19 pandemic.

The coronavirus disease 2019 (COVID-19) pandemic has had a detrimental effect on people's mental health. Drawing on the palliative function of ideologies, we suggest that people rely on system-justifying beliefs to mitigate psychological distress during the pandemic. We conducted three studies with correlational and experimental designs to examine whether and how system-justifying beliefs can buffer against psychological distress during COVID-19, and whether this effect may vary across social classes.

Rejection of the status quo: Conspiracy theories and preference for alternative political systems.

Conspiracy theories introduce a democratic paradox, as belief in conspiracy theories predicts support for both democratic and non-democratic political systems. In this article, we explore whether democratic and anti-democratic attitudes, resulting from conspiracy beliefs, can be mutually exclusive. In Study 1 (United Kingdom, N = 293), we show that belief in conspiracy theories is associated with decreased support for representative democracy, and increased support for direct democracy, anarchism, and autocracy within the same individuals.

Anti-establishment sentiments: realistic and symbolic threat appraisals predict populist attitudes and conspiracy mentality.

Previous research has found that populist attitudes and conspiracy mentality - here summarised as anti-establishment attitudes - increase when people feel threatened. Two types of intergroup threat have been distinguished, namely realistic threats (pertaining to socio-economic resources, climate, or health), and symbolic threats (pertaining to cultural values). However, there is no agreement on which types of threat and corresponding appraisals would be most important in predicting anti-establishment attitudes.

Why do users continue to contribute to darknet Child Sexual Abuse Material forums? Examining social exchange, social capital, and social learning explanations using digital forensic artifacts.

Background: The darknet hosts an increasing number of hidden services dedicated to the distribution of child sexual abuse material (CSAM). Given that by contributing CSAM to the forum members subject themselves to criminal prosecution, questions regarding the motivation for members contributing to darknet CSAM forums arise.

Objective: Building on insights gained from research into clearnet communities, here we examine the extent to which social incentives generated by the online CSAM community may explain members' posting behavior on darknet CSAM forums.

It's Just a Distance Thing: Affordances and Decisions in Online Disclosure of Sexual Violence Victimization.

The Internet offers an alternative context in which personal experiences with sexual violence can be shared. It has been suggested that victims experience lower barriers to disclosing their stories in a digital environment due to an online disinhibition effect and mainly anonymity. However, little is known about the lived experiences of victims who have shared their experiences online regarding these disinhibiting affordances of the Internet.

How perceived coercion polarizes unvaccinated people: The mediating role of conspiracy beliefs.

During the COVID-19 pandemic, different policies were implemented to increase vaccination uptake. Meanwhile, conspiracy theories spread widely, and vaccinated versus unvaccinated people increasingly polarized against each other. This study examined the associations between perceived vaccination coercion, conspiracy beliefs and polarization.

Procedural Justice in Their Eyes: A Qualitative Interview Study Among Detainees.

The literature on procedural justice has been mainly focused on examining whether a fair and respectful treatment affects justice-involved individuals' legitimacy evaluations and their behavior. It is, however, equally important to examine (a) the role that perceptions of procedural justice play for individuals in their encounters with criminal justice authorities and (b) what makes individuals feel treated procedurally (un-)just. In this qualitative study, semi-structured interviews were conducted with 35 detainees in a Dutch prison, asking questions about their encounters with police officers, prison staff, judges, and probation officers.

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.

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.

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.

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.

"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.

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.
