Development and Validation of a Method Using Dried Oral Fluid Spot to Determine Drugs of Abuse

A liquid chromatography–mass spectrometry method using dried oral fluid spots was developed and validated for the simultaneous quantification of cocaine, benzoylecgonine, cocaethylene, amphetamine, and 3,4‐methylenedioxymethamphetamine. The oral fluid was applied to a Whatman 903 grade paper and submitted to a drying time of 2.5 h. The extraction procedure was optimized by chemometric approach using simplex centroid design. Spots were extracted with a mixture of acetonitrile, buffer, and methanol. Calibration curves covered a linear concentration range of 40–500 ng/mL. Validation parameters of linearity, precision, accuracy, selectivity, carryover, matrix effects, and stability were evaluated and showed satisfactory results. Spot homogeneity was also satisfactory, with less than 15% of deviation from nominal concentration. Spot volume did not influence accuracy when less than 100 μL of the sample was applied to the spot. The validation of the proposed method suggests a potential application in different scenarios in toxicology.     

Changing patterns of drug and alcohol use in fatally injured drivers in Washington State

We have previously reported on patterns of drug and alcohol use in fatally injured drivers in Washington State. Here we revisit that population to examine how drug use patterns have changed in the intervening 9 years. Blood and serum specimens from drivers who died within 4 h of a traffic accident between February 1, 2001, and January 31, 2002, were analyzed for illicit and therapeutic drugs and alcohol. Drugs when present were quantitated. Samples suitable for testing were obtained from 370 fatally injured drivers. Alcohol was detected above 0.01 g/100 mL in 41% of cases. The mean alcohol concentration for those cases was 0.17 g/100 mL (range 0.02-0.39 g/100 mL). Central nervous system (CNS) active drugs were detected in 144 (39%) cases. CNS depressants including carisoprodol, diazepam, hydrocodone, diphenhydramine, amitriptyline, and others were detected in 52 cases (14.1%), cannabinoids were detected in 47 cases (12.7%), CNS stimulants (cocaine and amphetamines) were detected in 36 cases (9.7%), and narcotic analgesics (excluding morphine which is often administered iatrogenically in trauma cases) were detected in 12 cases (3.2%). For those cases which tested positive for alcohol c. 40% had other drugs present which have the potential to cause or contribute to the driver's impairment. Our report also considers the blood drug concentrations in the context of their interpretability with respect to driving impairment. The data reveal that over the past decade, while alcohol use has declined, some drug use, notably methamphetamine, has increased significantly (from 1.89% to 4.86% of fatally injured drivers) between 1992 and 2002. Combined drug and alcohol use is a very significant pattern in this population and is probably overlooked in DUI enforcement programs.     

Mending the Divide: Lessons from LGBTQ+ Movements for Latin American Studies

Latin American has made remarkable progress in the last twenty years regarding LGBTQ+ rights. More recently, LGBTQ-related issues have had major impacts on national and regional politics. However, most of the literature about Latin American social movements still largely ignores LGBTQ+ movements. This article argues that including LGBTQ+ movements in social movements research is essential to further our understanding of LGBTQ+ politics in the region and of Latin American politics and social movements more broadly, as well as to address the enduring lack of academic engagement with gender and sexuality as political topics.     

Organization of family labor and fertility in rural Mexico

The relationship between the organization of a family's work force and fertility in rural Mexico is assessed. The data are from the 1981 Rural Family Planning Survey, which covered approximately 8,000 households. Four groups are examined separately: farmers, agricultural wage earners, self-employed, and nonagricultural wage earners. Consideration is given both to fertility differentials among these groups and to differences in levels of contraceptive practice. (SUMMARY IN ENG)

Offender-focused police intervention in residential burglary and theft from vehicle hot spots: a partially blocked randomized control trial

Objectives

To test an offender-focused police intervention in residential burglary and residential theft from vehicle hot spots and its effect on crime, arrests, and offender recidivism. The intervention was prevention-focused, in which detectives contacted offenders and their families at their homes to discourage criminal activity.

Methods

The study was a partially blocked, randomized controlled field experiment in 24 treatment and 24 control hot spots in one suburban city with average crime levels. Negative binomial and ordinary least squares (OLS) regression were used to test the effect of the presence of intervention and its dosage on crime and offender recidivism, and examination of average and standardized treatment effects were conducted.

Results

The analyses of the hot spot impact measures did not reveal significant results to indicate that the treatment had an effect on crime or arrest counts, or on repeat arrests of the targeted or non-targeted offenders living in the hot spots. However, the relationships, while not significant, were in a promising direction.

Conclusions

The collective findings from all four impact measures suggest that the intervention may have had some influence on the targeted offenders, as well as in the treatment hot spots. So, while the experimental results did not show an impact, they are promising. Limitations include large hot spots, the low case number, low base rates, and inadequate impact measures. Suggestions are provided for police agencies and researchers for implementing preventive offender-focused strategies and conducting studies in suburban cities.

How to overcome the cost of a criminal record for getting hired

Many theories emphasize how employment is protective against criminal recidivism, yet a criminal record is a major barrier for getting hired. We asked 591 managers to make hypothetical hiring decisions between two applicants whose key difference was the presence or absence of a criminal conviction. In addition, we randomly manipulated the education, references, wage, or experience of the applicant with the criminal record to identify which manipulations can offset the cost of the record on an applicant's probability of being selected. We found that, when credentials were the same, the applicant with a criminal record was unlikely to be hired. That applicant, however, could become likely to be hired (i.e., the likelihood crossed 50 percent) by having at least 1 year of relevant experience, a GED or a college degree, or references from a former employer or a professor. Incomplete degrees, references from criminal justice professionals, or wage discounts did not make the applicant with the record likely to be hired. Findings confirm that a criminal record carries a high employability cost but also indicate that this cost can be superseded by specific credentials that signal an applicant's reliability, which can be provided by existing programs and institutions.     

Detection of Pb,Ba, and Sb in Cadaveric Maggots and Pupae by ICP-MS*

The concentrations of lead (Pb), barium (Ba), and antimony (Sb), characteristic of GSR, were determined in soil sediments and immature (larvae) of cadaveric flies of the family Calliphoridae, by inductively coupled plasma mass spectrometry (ICP-MS). This research refers to a case study from two real crime scenes in which the corpses were in an advanced state of decomposition. In case 1, the victim had holes similar to gunshot wounds, and in case 2, there was no evidence of perforations in the corpse. Soil sediment collection was performed at three different points of the terrain, at a minimum distance of 10 m from the corpse, for cases 1 and 2. In relation to the collection of immatures, larvae were collected in regions of the mouth, nose, and orifices similar to the entry of firearms projectile into the body, for case 1, and collection of larvae and pupae, located on the body and underneath it, for case 2. It was possible to detect and quantify the three elements of interest (Pb, Ba, and Sb) by ICP-MS in both sediment and cadaveric larvae. Concentrations of 4.44, 8.74, and 0.08 μg/g were obtained for Pb, Ba, and Sb, respectively, in the soil for case 1. For the case 2, the concentrations in Pb, Ba, and Sb were from 16.34 to 26.02 μg/g; from 32.64 to 57.97 μg/g and from 0.042 to 0.30 μg/g, respectively. In the larvae, Pb, Ba, and Sb were quantified in cases 1 and 2 with a concentration of 6.28 and 1.78 μg/g for Pb, 1.49 and 2.94 μg/g for Ba, 0.50 μg/g and <LD for Sb, respectively. These new results present the detection of characteristic elements of GSR in cadaveric larvae in humans in a real crime scene, besides highlighting the importance of the study of immature flies, using the ICP-MS technique in forensic analysis.     

A four-phase process for translating research into police practice

ABSTRACT

This article presents a framework that extends the discussion of translational criminology and the dynamic process of translating research to practice. The goal is to provide an explicit dissection of the translation process into four phases to help outline a structured way of thinking about how to incorporate research into police practice. The four-phases include: Phase I: ‘Does it Work?’ Research and Evaluation; Phase II: ‘What Works?’ Synthesis and Dissemination; Phase III: ‘How to Make it Work?’ Implementation and Evaluation; and Phase IV: ‘Make it Work!’ Institutionalization and Sustainability. The process is founded in implementation science and the ‘Knowledge to Action’ model (KTA) used in the medical and public health fields, as well as current translation activities for policing, and the authors’ experience as practitioners, researchers, and ‘translators’ over the last 25 years. It is the hope that parsing out four distinct phases for the translation of research to practice will assist researchers and police leaders to identify and fill gaps in current and future translation activities.
