Cases of Kava Impairment in Iowa Drivers

Kava is an Oceanic plant in which the root is consumed as a beverage and is becoming increasingly popular. The effects of kava consumption may include sedation, euphoria, and impairment of motor coordination. This article demonstrates kava impairment through four cases of self‐reported kava use supported with Drug Recognition Expert (DRE) evaluations of each subject. Subject's urines screened negative for common drugs of abuse by immunoassay analysis. Urine from cases 3 and 4 were analyzed by liquid chromatography–tandem mass spectrometry, and gas chromatography–mass spectrometry, which yielded the presence of kavalactones. Subjects exhibited poor driving behavior and signs of intoxication. Indicators of impairment from multiple drug categories, central nervous system (CNS) depressants, CNS stimulants, and cannabis were observed, which may be consistent with the presence of multiple kavalactones and their diverse array of mechanisms of action. The consumption of kava can hinder one's ability to operate a vehicle safely.     

Exposure to Intimate Partner Violence Amongst Women of Reproductive Age in Lagos,Nigeria: Prevalence and Predictors

Research on predictors of Intimate Partner Violence (IPV) in Sub-Saharan Africa is contradictory, necessitating further investigation. This study sought the prevalence and predictors of IPV among women in Lagos, Nigeria. Questionnaire data from 934 women visiting an obstetrics and gynecology clinic in Lagos were analyzed using multivariable methods. The 1 year prevalence of IPV was 29%, with significant proportions reporting psychological (23%), physical (9%) and sexual (8%) abuse. In-access to information, women’s autonomy and contribution to household expenses independently predicted IPV. The findings provide new incites for IPV prevention in Lagos with implications for further research.     

The “new” view of investment decisions and public policy analysis: An application to green lights and cold refrigerators

Recent research in investment theory emphasizes the importance of sunk investment costs, uncertainty in returns, and flexibility in investment timing. Allowing for the presence of these characteristics alters traditional discounted cash flow rules for when to invest. Those rules will recommend investing at lower rate-of-retum thresholds than is optimal. This article describes this research and suggests the range of potential situations to which the theory applies. It also discusses the implications for policy analysis and suggests that government programs to encourage investment may, in some cases, be inappropriate. After discussing a wide array of possible applications, we focus on one in particular: programs to encourage energy-efficient investment. The examples suggest the importance of applying the new investment theory for economic analysis of investment in energy-efficient technologies.     

Crime and the Czech Republic: Summary observations

Increased levels of street and organized crime activity have accompanied the transition from totalitarian rule to a freer political climate both in the Soviet Union and in its former east European satellites. A conference in the Czech Republic involving officials from the host country and visiting practitioners and academics largely from the United States considered methods for dealing with burgeoning crime issues. The article summarizes the tone and content of the discussions as well as the substantive issues addressed.

Truman's revenge: Social control and corporate crime

Many criminologists have found that corporate crime does more harm than street crime, whether measured by property lost, money stolen, or lives taken. Yet, public concern about crime is almost exclusively focused on street crime and “just deserts” for the offender. The authors argue that corporate criminality is more likely than individual criminality to be planned and subjected to cost/benefit analysis than street crime and therefore more likely to be deterred by raising the costs of corporate criminality. The Model Penal Code is used to demonstrate that both individual and corporate crime produce a comparable array of avoidable harms. Public policies that demand just deserts for individual offenders (natural persons) are revealed as highly inconsistent with policies that protect corporations (juristic persons) from accountability for the harms they create. A philosophical and legal foundation for corporate crime control strategies is provided. The authors propose a sanctions regime for corporate criminals comparable to the sanctions regime imposed on natural persons for street crimes. Strategies to avoid risk shifting by corporations are suggested. This revised version was published online in July 2006 with corrections to the Cover Date.
