Executions as a deterrent to homicide

For the period 1977-1992, the number of homicides in a state tended to decrease more often after a year of no executions than after a year with one or more executions, the opposite of a deterrent effect.     

Manic-depressive tendencies, suicidality, and perfectionism

In a sample of 82 college students, depression scores, but not manic scores, were associated with both perfectionism and imposter scores.     

Steven Stack's ecological research on suicide applied to homicide

In a sample of 72 nations in 1980, birth rates proved to be the strongest predictor of national homicide rates.     

Motivations for preventing versus assisting suicide

The motivations of those seeking to prevent and assist suicide are conceptualized as defensive styles of repression versus sensitization adopted to deal with personal suicidal desires.     

Accumulation of Risk and Promotive Factors Among Young Children in US Military Families

In the families of the new cohort of war veterans now entering the civilian population in the United States are over two million young children (Cozza, Haskins & Lerner, 2013; Institute of Medicine, 2013). Several noteworthy studies have shown that children exposed to separation from a parent due to combat‐related deployment are at elevated risk for a variety of negative consequences (Lester & Flake, 2013). Cozza et al. (2013) argue that existing studies of military children focus too much on the stresses or deficits they experience, failing to give sufficient attention to their strengths, the strengths of their families, or the supports around them. In the current study we focus on risk and promotive factors in the lives of children aged 0–10 in military families. We examine the likelihood of negative outcomes as functions of additive, cumulative, and interactive relationships between risk and promotive factors and children's outcomes. Risk factors, particularly parental depression, community poverty, and cumulative risk, were more strongly associated with children's outcomes than promotive factors. There was, however, a significant risk‐protective relationship between accumulations of risk and promotive factors, consistent with promotive conditions operating in a protective fashion under conditions of elevated risk.
