The Effect of Varying the Composition of Fingerprint Sweat Deposits on the Corrosion of Brass and Fingerprint Visibility

Corrosion of α‐phase brass by sebaceous sweat fingerprint deposits produced identifiable impressions in a majority of samples (n = 40) 4 days after deposition. Combining sebaceous with eccrine sweat yielded a greater percentage of identifiable fingerprint deposits, although this increase was not statistically significant. Production of identifiable fingerprints from eccrine sweat deposits was dependent on the sampling time of year with deposits taken during summer months giving similar percentages of identifiable fingerprints to sebaceous deposits. A statistically significant positive correlation was found between elapsed days after deposition and identifiable eccrine (ρ = 0.787, p < 0.05), sebaceous (ρ = 0.724, p < 0.05), and eccrine/sebaceous mixture (ρ = 0.908, p < 0.01) fingerprints deposited during summer months. The summer increase in the percentage of identifiable eccrine sweat deposits was statistically significant compared to winter eccrine deposits (p < 0.0001). Observations were consistent with results obtained from artificial sebaceous and eccrine sweat.     

ADOLESCENT DRUG USERS: THE JUSTICE SYSTEM IS MISSING AN IMPORTANT OPPORTUNITY

A significant number of youth and young adults who use drugs have fallen through the cracks of our juvenile and adult justice systems in terms of receiving any meaningful services. The situation is due to a number of factors, including the reliance on adolescent self reporting utilized by most of the research, the failure of justice and other systems to routinely assess youth for either current drug use or indicia of drug use (e.g., "resiliency" or "protective" factors), and confidentiality and other restrictions pertaining to access to juvenile justice system information. Yet, retrospective reviews of drug use patterns for adults in the criminal justice system make it clear that drug use is beginning for most of these offenders during adolescence or before. This article urges (1) juvenile courts to develop mechanisms for systematically screening youth who come into the system for drug use and/or propensities for drug use and (2) adult courts to embark on similar strategies and to develop adolescent tracks that would be geared to providing the services these youth (despite their chronological age) need and would otherwise not receive in the adult system.     

Performance characteristics of the Cozart RapiScan Oral Fluid Drug Testing System for opiates in comparison to ELISA and GC/MS following controlled codeine administration

Oral fluid is an interesting alternative matrix for drug testing in many environments, including law enforcement, workplace drug testing, and drug treatment facilities. Performance characteristics of the FDA-cleared, qualitative, Cozart RapiScan Opiate Oral Fluid Drug Testing System (Opiate Cozart RapiScan System or Opiate CRS) were compared to the semi-quantitative Cozart Microplate EIA Opiate Oral Fluid Kit (Opiate ELISA) and to gas chromatography/mass spectrometry (GC/MS). The following oral fluid opiate cutoffs were evaluated: the GC/MS limit of quantification (LOQ) of 2.5 mg/l; 15 microg/l currently used for oral fluid testing in the United Kingdom (UK); 30 microg/l (Opiate CRS cutoff); and 40 microg/l, the proposed Substance Abuse and Mental Health Services Administration (SAMHSA) cutoff. Subjects provided informed consent to participate in this IRB-approved research and resided on the closed research ward throughout the study. Three oral codeine doses of 60 mg/70 kg were administered over a 7-day period. After a 3-week break, subjects received three doses of 120 mg/70 kg within 7 days. Oral fluid specimens (N = 1273) were analyzed for codeine (COD), norcodeine (NCOD), morphine (MOR) and normorphine (NMOR) by GC/MS with an LOQ of 2.5 microg/l for all analytes. MOR and NMOR were not detected in any sample; 26.5% of the specimens were positive for COD and 13.7% for NCOD. Opiate CRS uses a preset, qualitative cutoff of 10 microg/l; this is equivalent to 30 microg/l in undiluted oral fluid as the oral fluid collection process involves a 1:3 dilution with buffer. Sensitivity, specificity, and efficiency of Opiate CRS compared to Opiate ELISA were 98.6, 98.1, and 98.2% at a 30 microg/l cutoff and 99.0, 96.2, and 96.6% at a 40 microg/l cutoff. Compared to the much lower GC/MS LOQ of 2.5 microg/l, sensitivity, specificity and efficiency were 66.8, 99.3 and 90.7%. Increasing the GC/MS cutoff to the current UK level yielded performance characteristics of 81.5% (sensitivity), 99.3% (specificity), and 95.4% (efficiency). Using a GC/MS cutoff identical to the preset Opiate CRS cutoff yielded sensitivity, specificity, and efficiency of 88.5, 99.2, and 97.5%, respectively. At the proposed SAMSHA confirmation cutoff of 40 microg/l, sensitivity increased with little change in specificity and efficiency (91.3% sensitivity, 98.9% specificity, and 97.5% efficiency). Oral fluid is a suitable matrix for detecting drugs of abuse. Opiate CRS, with a 30 microg/l cutoff, is sufficiently sensitive, specific and efficient for oral fluid opiate analysis, performing similarly to Opiate ELISA at the same cutoff, and having performance characteristics >91% when compared to GC/MS at the proposed SAMHSA cutoff.     

Parents' perception of adolescent behavior problems

Fifty-seven parents, usually mothers, rated their adolescent sons and daughters on the Walker Checklist at the time of their initial clinic appointment. Parents perceived this group of adolescents as more disturbed than the elementary school age normative group on three of the scales, Immaturity, Acting Out, and Distractibility. The results support an increase in behavior problems at adolescence which is more marked for the younger females and younger males. Neither gender nor age, separately, determines the degree of behavioral disturbance, with one exception. The scores of both the younger and older male groups are significantly higher than the scores of their corresponding female groups on the school-related Distractibility scale.Received her Ph.D. from University of Washington 1959.

Predictor Variables in Competency to Stand Trial Decisions

Clinicians possess significant discretion in competency to stand trial assessment. Therefore, it is paramount to explore the contribution of individual variables to ensure that the decision-making process is devoid of bias and solely relates to the legal criterion. To test for the possibility of bias in clinical decision-making, we examined the predictive efficiency of clinical, criminological, and sociodemographic variables in a sample of 468 criminal defendants referred for competency evaluations. Only clinical diagnostic variables and employment status were significant predictors. This finding supports the idea that examiner decisions of competency appear to be unbiased and relate primarily to a defendant's functional ability.     

Chimeric governance and the extension of resource regulation

The contemporary securitisation of underdevelopment is based on the myth of mutual vulnerability—the idea that underdevelopment and state failure pose diverse threats both to the developed world and the poor in the developing world. The mutual vulnerability thesis provides the rationale for an attempt to expand the range of both military and regulatory interventions inside the developing world. The promise of these interventions is of a synthesis between security for the developed world and solidarism with the poor. The reality is a form of chimeric governance which purports to protect the rich from a range of imagined threats and which masks an unwillingness to really address the problems of the poor.

One illusion has been shattered on 11 September: that we can have the good life of the West irrespective of the state of the rest of the world…. Once chaos and strife have got a grip on a region or a country trouble will soon be exported. Out of such regions and countries come humanitarian tragedies, centres for trafficking in weapons, drugs and people, havens for criminal organisations, and sanctuaries for terrorists…. The dragon's teeth are planted in the fertile soil of wrongs unrighted, of disputes left to fester for years, of failed states, of poverty and deprivation.1 ?1.

Neutral heroin impurities from tetrahydrobenzylisoquinoline alkaloids

Laudanosine, reticuline, codamine, and laudanine are members of the tetrahydrobenzylisoquinoline family of natural products. These alkaloids are present in the opium poppy, Papaver somniferum, and are subsequently found as impurities in clandestinely processed morphine. Morphine is then synthesized to heroin using hot acetic anhydride. During the course of this study, it was determined that these four tetrahydrobenzylisoquinolines undergo degradation to a series of 18 neutral impurities when subjected to hot acetic anhydride. Based on the degradation pathway, these new impurities were categorized into two sets of impurities called the C1-acetates compounds and the stilbene compounds. Synthesis, isolation, and structural elucidation information is provided for the tetrahydrobenzylisoquinoline alkaloids, and the new neutral impurities have been studied. Several hundred authentic heroin samples were analyzed using an established heroin signature program method. This methodology features the detection of trace neutral impurities present in heroin samples. It was determined that all 18 new impurities were detected in various quantities in four different types of heroin samples. Analytical results featuring these new impurities are reported for South American-, Southwest Asian-, Mexican-, and Southeast Asian-type heroin samples. These new impurities, coupled with other established forensic markers, enhance the ability to classify illicit heroin samples.     

Professionalization and unionization of police: A Delphi forecast on police values

The Delphi Forecasting technique was utilized to assess the general direction and magnitude of broad future trends in the occupationally-related values of police officers. Two panels of experts were established and utilized in the Delphi Process: one composed of veteran police officers and the other consisting of law enforcement educators, top echelon police administrators, attorneys, and social ethicists.Two major trends emerged in the course of the study: a movement toward professionalization and a movement toward unionization. These two movements were found to embody generally conflicting sets of occupationally-related values.The increasing emphasis of police chiefs and their administrators on managerial efficiency was identified as the critical factor influencing the future of these trends.     

The biological concept of race and its application to public health and epidemiology

The category of race is widely used in public health. Although its significance may be clear-cut in some practical situations, an adequate theoretical construct for the concept of race does not exist. Public health appears to lag far behind the other biological sciences in the effort to grapple with the idea of race and its implications for the nature-nurture question. This paper outlines the current anthropological and social perspective on race, and applies this view to problems of disease epidemiology. It is proposed that uncritical use of the traditional biological concept of race has distorted etiological thinking in public health and has proven an obstacle in the development of effective intervention strategies. The pragmatism of medicine and its isolation from social science may account for much of this backwardness.
