Rates of youth firearm exposure and carriage are well-established, but less work has examined how exposure to police violence and firearm violence, as victim or witness, may be associated with beliefs in gun ownership for society or access to guns. This study used survey data from a multiracial sample of 276 youth living in New Orleans, Louisiana…

The issue of school safety has been interrogated as school shootings have occurred multiple times each year in the United States. This devastating reality has captured the attention of many throughout the United States. School leaders have implemented strategies to increase school safety, including the creation of practices to deter shooting…

Objective: Examine the proportion of students with rapid firearm access and associations with recent alcohol and marijuana use. Participants: Cross-sectional data from college freshmen (n = 183) in 2020 who participated in the "Mason: Health Starts Here" study. Methods: Using logistic regression, associations were examined between past…

Research on firearm purchaser licensing laws has found population level reductions in firearm-related mortality. Limited research has been conducted specifically examining the impact of these laws among adolescents and emerging adults. We obtained death data from the National Center for Health Statistics from 1990 to 2019. We generated state-year…

Perceptual expertise is typically domain-specific and rarely generalises beyond an expert's domain of experience. Forensic feature-comparison examiners outperform the norm in domain-specific visual comparison, but emerging research suggests that they show advantages on other similar tasks outside their domain of expertise. For example, fingerprint…

This paper examines the impact of high-fatality school shootings on the subsequent outcomes of the survivors of those events. We focus specifically on the shootings at Columbine High School (Littleton, CO), Sandy Hook Elementary (Newtown, CT), and Marjorie Stoneman Douglas High School (Parkland, FL). We assess the subsequent educational record,…

Between 2014 and 2018, at least 974 youth were fatally shot by the police. Racial disparities in fatal police shootings (FPS) have been well-established in existing research, but less attention has been paid to patterns in fatal police encounters with youth. This study uses a multisource and externally validated research design to track cases of…

While previous studies have assessed public opinions for arming teachers in K-12 schools in the United States, comparatively less research has focused on understanding teachers' opinions for such policies and assessed whether and to what extent school- and individual-level factors are associated with differences in support. The current study aims…

Youth interpersonal firearm violence disproportionately affects Black youth, with residential racial segregation as a key determinant. Racially segregated neighborhoods, which are economically isolated (e.g., neighborhood disadvantage), are linked to increased exposure to violence. This exposure, in turn, is a determinant of youth firearm…

Observers' memory for a person's appearance can be compromised by the presence of a weapon, a phenomenon known as the weapon-focus effect (WFE). According to the unusual-item hypothesis, attention shifts from the perpetrator to the weapon because a weapon is an unusual object in many contexts. To test this assumption, we monitored participants'…

Scholars theorize that the nature of school gun violence varies across school settings. Yet, there is a lack of statistical research testing this idea. This study investigates contextual factors associated with six forms of school gun incidents (N = 1,238) over a 40-year period (1980-2019) in the United States. To conduct the analyses, school,…

Over the years, Nigerian society has the belief that given the potency of kánàkò (collision of time and space) and egbé (teleportation), it can only be applied by men while neglecting the role of women in its application for national safety. The study examines egbé and kánako and implications for community policing and women's involvement in…

Background: School shooting events and lockdowns have increased in the United States, raising concerns about their impact on youth mental health. Method: This study assessed the association between school lockdowns and changes in youth mental health in 10,049 children who participated in the Adolescent Brain and Cognitive Development study. The…

Rural adolescents are at risk for firearm-related injury and death. In response, professional organizations have called for communication between adolescents, parents, and providers about firearms. A shared understanding of firearms between providers and families can facilitate effectiveness of health interventions. However, few studies engage…

Using data from its national university entrance exam, we examined the relationship between armed conflict and student achievement in Afghanistan. Exploiting the province-year variation in exposure to conflict intensity, we estimated the relationship between conflict and exam results generally and by gender for all test takers from 2014-2019.…
