Evaluation of the Cozart RapiScan drug test system for opiates and cocaine in oral fluid

The purpose of this study was to evaluate the efficiency of the Cozart^® RapiScan (CRS) drug test system for detecting opiates and cocaine in oral fluid. Oral fluid samples were collected using the Cozart^® RapiScan collection system from 358 donors who were receiving treatment for their addiction and were monitored for drug misuse. A further 103 oral fluid samples were collected from volunteer donors who were not drug users. The samples were analyzed in the laboratory using the two-panel Cozart^® RapiScan cartridge for opiates and cocaine and confirmed using gas chromatography–mass spectrometry (GC–MS). The samples were stored frozen at −20 °C until analysis by GC–MS. The overall accuracy of the CRS for both opiates and cocaine was 100%. Samples spiked at 50% above and below the cut-off consistently gave negative and positive results respectively. A total of 88 samples were positive for various opiates and 111 samples were positive for cocaine and/or its metabolites. The CRS for opiates and cocaine in oral fluid, using a cut-off of 30 ng/mL morphine or benzoylecgonine equivalents in neat oral fluid, had overall efficiencies of 98% and 99%, respectively, versus GC–MS. A series of potential adulterants of oral fluid were evaluated and shown not to alter the outcome of the test result.     

A Study of Juror and Jury Judgments in Civil Cases: Deciding Liability for Punitive Damages

A study was conducted to investigate civil juries' decisions concerning defendants' liability for punitive damages in tort cases. A total of 121 six-member mock juries composed of jury-service-eligible citizens were presented summaries of previously decided cases and given a comprehensive instruction on the defendant's liability for punitive damages. Most of the mock juries decided that the consideration of punitive damages was warranted, although appellate and trial judges had concluded that they were not warranted. The tendency to find the defendant liable was partly due to jurors' failure systematically to consider the full set of legally necessary conditions for the verdicts they rendered. Individual differences in the jurors' backgrounds were not strongly related to their verdicts; income and ethnicity were weakly related to judgments. The social processes in deliberation on civil juries were similar to the dynamics of deliberation that have been observed in criminal juries.     

Forecasting the 2016 General Election in Jamaica

The objective of the article is to explain the methodologies and the findings of the 2016 Jamaican General Election forecasts. The Good Judgment Project’s CHAMPSKNOW system was applied using qualitative and quantitative methods. The research question was: what were the probabilities of the Jamaica Labour Party (JLP) or the People’s National Party (PNP) winning the 25 February 2016 General Election? The data were drawn from election results and macro-economic variables from 1962 to 2015; polls from 1976 to 2016; campaign ads; election newspaper stories; constituency fund disbursements and independent surveys in marginal seats. The results showed that the JLP had a greater number of ads with better and clearer policy contents than the PNP ads. The JLP also received more positive news coverage during the campaign. MPs who spent a large part of their constituency funds on welfare were more likely to win. The PNP had more garrison, traditional and marginal seats than the JLP so the PNP had the edge. Moreover, the data from the independent surveys and the macro-economic analyses indicated the likelihood of a PNP win. The national polls revealed a statistical dead heat but the forecasts started with the governing PNP having a slightly greater probability of winning because of its active political business cycle in which the PNP was rolling out programmes throughout the country in the election year. The forecasts were revised when the JLP narrowed the gap because the PNP refused to participate in the national debate, which generated negative news about the PNP. The final forecast said the election would be close with the PNP having the edge. However, the JLP’s tax plan was a wild card, which gave the party the edge with a one-seat victory.     

Psychopathy and Culpability: How Responsible Is the Psychopath for Criminal Wrongdoing?

Recent research into the psychological and neurobiological underpinnings of psychopathy has raised the question of whether, or to what degree, psychopaths should be considered morally and criminally responsible for their actions. In this article, we review the current empirical literature on psychopathy, focusing particularly on deficits in moral reasoning, and consider several potential conclusions that could be drawn based on this evidence. Our analysis of the empirical evidence on psychopathy suggests that while psychopaths do not meet the criteria for full criminal responsibility, they nonetheless retain some criminal responsibility. We conclude, by introducing the notion of rights as correlative, that even if psychopaths were to be fully nonresponsible, imposing some form of civil commitment would still be warranted.
