Proficiency testing (external quality assessment) of drug detection in oral fluid

Eighteen external quality assessment (proficiency testing) samples were prepared from client specimens collected with the Intercept^® oral fluid collection device and by spiking drug-free oral fluid. Samples were circulated in pairs at quarterly intervals to 13 UK and USA based laboratories for analysis by a panel of OraSure micro-plate Intercept^® enzyme immunoassay kits and hyphenated mass spectrophotometric techniques. During the survey, there was a single case of non-specificity in a false report for methadone. The major errors were of lack of sensitivity relative to the concentration thresholds specified for the immunoassays. The sensitivity for overall ‘present’/‘not found’ reports calculated as true positives/(true positives + false negatives) were for the amfetamine specific assay 50%, methyl-amfetamines 93%, barbiturates 64%, cannabinoids 73%, cocaine and metabolites 100%, benzodiazepines 69%, methadone 95%, opiates 79% (opiates excluding oxycodone 93%), phencyclidine 93% and human gamma-globulin 97%. A small number of the sensitivity errors were attributable to errors in chromatographic confirmation techniques.

Consent and its meaning to the sexual victimization of women

Two conditions must be met in order for a person to be rightly considered the victim of a crime. First, there must be the victim of some form of harm. Second, the harm in question was the direct result of an act in which the harmed individual did not knowingly consent to take part. What are the dynamics of consent and how important should consent be in defining and placing criminal responsibility in crimes where women are sexually victimized? Finally, how does the conceptualization of victimization change when viewed from liberal and radical feminist perspectives?     

Reviews

Recently, various authors have examined the relationship between growth in government size and total economic growth. In each case, the authors permitted only a monotonic relationship. This paper examines the issue of a non-linear relationship between growth in government and overall growth in the economy.Government contributes to total economic output in various ways. The provision of Pigovian public goods enhances the productivity of the private sector inputs increasing total output. However, the public decision-making process can result in an inefficient quantity of public goods. The likelihood of this outcome increases with the size of government. Further negative effects are created by the revenue raising and spending mechanisms of government, and the increasing diversion of resources into unproductive rent-seeking activities. The magnitude of these effects is likely to increase with the relative size of government.     

Assessment of competency for execution? A guide for mental health professionals

Assessment of competency for execution presents two compelling ethical questions for mental health professionals: whether clinicians can ethically provide such assessment, and if so, how it should be done in order to maximize quality and minimize ethical conflict. In this article we address the issue of whether to participate and, if so, how. The question of whether to participate is discussed by summarizing the arguments for and against participation and offering guidelines for making a decision. The question of how to proceed is discussed in two contexts: preadjudication (before a formal decision about competency) and postadjudication (following a determination of "incompetent" and transfer of the offender to another facility for treatment and further assessment). Finally, recommendations are made regarding research that would improve the quality of execution competency assessments.     

Rural Development Councils: An Intergovernmental Coordination Experiment

Eight pilot state Rural Development Councils were establishedby the federal government in 1990 to coordinate rural developmentefforts among federal departments and agencies and to establishcollaborative relationships with states, local governments,and the private sector. After one year of operation, these councilsprovided a mechanism for the participating states to definethe rural issues relevant to their unique settings and to worktoward the accomplishment of their goals. In addition, the processallowed federal officials in Washington and in the states toutilize the discretion available in the system to maximize collaborationand cooperation. Additional states will be involved in the effortin 1992. Three types of agendas or expectations surrounded theinitiative: substantive, political, and process approaches.Although it is too early to determine the extent to which thecouncils have "delivered" on these expectations, the experimentprovides preliminary evidence of the scope of federal abilityto stimulate change within a state as well as the economic andpolitical forces that constrain it.     

The transition of migratory patterns in medium-sized cities

"The authors attempt to present some empirical findings regarding a phenomenon which they chose to call the 'transition in migratory patterns'.... The general hypothesis states that: changes in migratory patterns are due to an interaction between those economic, political and social processes which affect the distribution of the population; and that this interaction is also highly influenced by macroeconomic politics--an arena where technology plays a dominant role." Data are for Guadalajara and the state of Jalisco in Mexico. (SUMMARY IN ENG)
