Extending the General Theory of Crime to “The East:” Low Self-Control in Japanese Late Adolescents

This study examined the measurement of low self-control as well as the low self-control-deviance relationship in a sample of N = 335 Japanese late adolescents. Participants completed the Grasmick et al. low self-control instrument and the Normative Deviance Scale (NDS). Findings indicated that the low self-control measure was a valid and reliable indicator of low self-control among male and female Japanese late adolescents and that it was multi-dimensional. Furthermore, the study provided evidence that low self-control was consistently related to diverse measures of deviance, ranging from trivial to more serious norm-violating behaviors (e.g., assault). Finally, in a series of comparisons of partial unstandardized regression coefficients between Japanese and U.S. late adolescents, the study found that the low self-control-deviance relationship was invariant across all measures of deviance with the exception of alcohol use. Findings are discussed in terms of their importance for cross-cultural/cross-national predictions made by the General Theory of Crime.     

The effects of delay on voice recognition accuracy

Two experiments were conducted in which 176 listeners heard male and female objectively defined high- and low-recognition voices and then attempted to identify these voices from a voice parade containing 20 distractors after either 10, 40, 100, or 130 minutes (experiment 1), or 10 minutes, one day, seven days, or 14 days (experiment 2). In experiment 1 delay had no overall effect, although further analysis revealed that the shortest delay did produce better performance than all other delay conditions. Further, high-recognition voices were better identified than low-recognition voices. In experiment 2 delay had an overall effect, with the shortest delay interval again being significantly better than all other conditions, which did not differ among themselves. High- and low-recognition voices, however, did not exhibit a statistically significant difference, although these two factors entered into a marginally significant interaction. Theoretical speculation and forensic implications were drawn.This research was funded by the British Home Office, research grant no.

A Decision Theoretic Model of Public Opinion: Guns, Butter, and European Common Defense

Why do individuals support the public policies they do? We argue that individuals can have quite sophisticated policy preferences and that not correctly modeling those preferences can lead to critically misspecified empirical models. To substantiate this position we derive and test a decision‐theoretic model that relies upon three critical assumptions: (1) policies affect the provision of multiple goods about which individuals care; (2) individuals have diminishing returns to scale in those goods; and (3) preferences over at least some subset of those goods are correlated. Using this model, we demonstrate that arbitrarily small secondary policy effects can confound predictions over primary policy effects. Thus, not considering even arbitrarily small policy effects can cause one to conclude that evidence is consistent with one's theory when in fact it is inconsistent or vice versa. Testing this theory on support for forming a European common defense, we find evidence consistent with our model.     

Evaluation of Non‐Natural Deaths among Veterans: New Mexico Medical Examiner‐Investigated Deaths, 2002–2011

While it is recognized that veterans have increased rates of depression, post‐traumatic stress disorder (PTSD), suicide, and substance use disorders, rates of homicide and unintentional injury deaths in veterans have been minimally investigated. We evaluated all non‐natural deaths in New Mexico veterans between 2002 and 2011 in comparison with non‐natural deaths among non‐veterans. We reviewed all decedents in New Mexico with a history of military service and investigated by the medical examiner, excluding natural deaths and deaths due to fall from standing height. The most common manner of death was unintentional injury (62%), most of these deaths due to motor vehicle accidents (29%) followed by unintentional overdose (26%). Suicide rates among veterans were consistently higher than the general population. The most common mechanism of suicide in men was gunshot wound (72%), and intentional overdose in women (49%). Services are needed for veterans that are tailored to all ages and both sexes.     

Post-Release Substance Abuse Treatment for Criminal Offenders: A Cost-Effectiveness Analysis

This study conducted a cost-effectiveness analysis of Delaware's CREST Outreach Center, a work release therapeutic community (TC) and aftercare program for criminal offenders. Treatment effectiveness was assessed using the number of days reincarcerated during an 18-month, post-release follow-up period. The 6-month CREST program cost $1937 for the average participant, and led to 30 fewer days incarcerated (29% less) than the average participant in a standard work release program. This implies that the CREST program reduced incarceration for criminal offenders at an average cost of $65 per day. The additional investment of $935 per client to provide aftercare services led to 49 fewer days incarcerated (43% less) than CREST work release-only participants. This suggests that by adding an aftercare component to the CREST work release program, a day of incarceration is avoided at an average cost of $19 per day. These findings have implications for future investments in post-release substance abuse treatment for criminal offenders. However, the results must be interpreted with caution given potential selection bias in the groups that participated in the CREST work release and aftercare programs. Selection bias and the policy implications of this research are noted and discussed.
