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 degrees 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.     

Toward a moral theory of negligence law

This paper explores how the widely acknowledged conception of tort law as corrective justice is to be applied to the law of negligence. Corrective justice is an ordering of transactions between two parties which restores them to an antecedent equality. It is thus incompatible with the comprehensive aggregation of utilitarianism, and it stands in easy harmony with Kantian moral notions. This conception of negligence law excludes both maximizing theories, such as Holmes' and Posner's, and Fried's risk pool, which combines Kantianism with distributive rather than corrective justice. Central to the Kantian approach is the impermissibility of self-preference. The two types of self-preference, self-preference in conception and self-preference in action can respectively account for the objective standard and the Learned Hand test, which are the two most characteristic features of negligence and which are generally (and wrongly) considered to be inescapably aggregative. This corrective justice conception of the negligence standard can then be compared to Epstein's corrective justice conception of strict liability, and arguments can be offered in favour of the superiority of the former.     

Political Ideology,Political Party,and Support for Greater Federal Spending on Environmental Protection in the United States: Evidence from the General Social Surveys, 1993–2018

This paper focuses on the effects of political ideology and party affiliation on support for more government spending on environmental protection. Pooled‐sample results show that Liberals (Democrats) are more likely to support higher government spending on environmental protection than Moderates (Independents), who, in turn, are more likely to support higher spending levels than Conservatives (Republicans). The results persist even when we control for respondents' opinions concerning whether the federal government, in general, does too little or too much. When stratifying by party, ideological divisions generally narrow, while stratifying by ideology leads to slightly wider divisions between Democrats and Republicans. Together, these results suggest that when Liberals and Conservatives form opinions about government spending on the environment, party affiliation, to some degree, dampens the effects of ideology. Between 2014 and 2018 the probability of supporting more environmental spending increased, albeit slightly, for all ideologies and parties, but more so for Liberals and Democrats.     

Conduct Problems Among Children at Battered Women's Shelters: Prevalence and Stability of Maternal Reports

The present research was designed to (1) replicate prevalence estimates of clinical levels of conduct problems in a large (n = 401) sample of children residing at a shelter for battered women, and (2) assess the stability of mothers' reports of child conduct problems following shelter departure. According to mothers' reports on standardized questionnaires and diagnostic interviews obtained during shelter residence, approximately one third of the children between 4 and 10 years of age exhibited clinical levels of conduct problems. Prior research has demonstrated elevated maternal distress during shelter residence and suggests that such distress may influence mothers' reports of child conduct problems. To examine this issue, a subset of families with children exhibiting clinical levels of conduct problems (n = 68) was reassessed following their shelter departure. Mothers' reports of child conduct problems remained stable despite significant reductions in mothers' distress after shelter exit.
