Fear generalization, a lack of discrimination between safe and unsafe cues, is a hallmark of posttraumatic stress disorder. The phosphodiesterase 5 (PDE5) regulates the cyclic guanosine monophosphate (cGMP) pathway, which has been proposed to be involved in fear memory generalization. However, whether PDE5 activity underlies fear memory generalization remains unexplored.

Over the past four decades, hundreds of studies have examined the presence of racial disparities in criminal punishment. The bulk of this research has been conducted in the United States and a few other western democracies, with limited research assessing the presence of racial disparities in criminal sentencing for homicides in South America. Using information gathered via original data collection on homicide cases from five different capital cities in Brazil, the current study examines two criminal court outcomes: whether a defendant was convicted and the length of sentence.

Research evaluating the relationship between work and crime has paid little attention to behavior in the workplace. We evaluate four hypotheses regarding the work-crime relationship: (1) Employment and crime are negatively related, (2) Employment displaces offending from the street to the workplace, (3) Work offending emboldens street offending, and (4) Work offending has no association with street offending. Drawing on longitudinal data from a high-risk sample of young adults from The Pathways to Desistance study, we use hybrid fixed effects models with measures of street property offending and workplace property offending to test the hypotheses.

Purpose: This study assesses the relationship between opioid mortality and homicide rates across 25 member countries of the organization for economic co-operation and development (OECD) over time and investigates the role of country-level public health expenditures in this relationship.

Methods: Fixed effects linear regression is used to assess the longitudinal association between opioid mortality and cross-national homicide rates in 25 OECD countries between 2000 and 2017. Moderation analyses are conducted to assess the interaction between opioid mortality rates and public health expenditures per capita.

Despite existing efforts to prevent bullying, research suggests that bullying remains a serious and common problem across the United States. Therefore, researchers should continuously propose and evaluate alternative policies that may mitigate bullying as a social issue. One such strategy that has been proposed is the use of police officers in schools, best known as School Resource Officers (SROs).
