Detection of cannabinoids in homicide victims and motor vehicle fatalities

A gas chromatographic/mass spectrometric (GC/MS) procedure is described for the detection and measurement of delta 9-tetrahydrocannabinol, 11-hydroxy-delta 9-tetrahydrocannabinol, and 11-nor-delta 9-tetrahydrocannabinol-9-carboxylic acid in blood, or 11-nor-delta 9-tetrahydrocannabinol-9-carboxylic acid in urine. About 50% of all homicide victims and motor vehicle drivers killed in Bexar County in 1985 were tested for the presence of cannabinoids. Of 130 homicides and 69 drivers tested, blood was analyzed primarily in all but 15 and 3 cases, respectively. In these latter cases, blood analyzed after urine was found to be positive. Of the homicide victims, 44 (34%), and of all drivers, 19 (28%), tested were positive for one or more of the cannabinoids. As a separate group, 16 motorcycle drivers tested had 38% positive as compared with 25% of the other vehicle drivers. Ethyl alcohol was present in 55% of the drivers, and in 63% of the homicide victims. Drugs other than alcohol or cannabinoids were found in 10% of the drivers, and in 12% of the homicide victims.     

EXPENDITURES ON CHILDREN AND VISITATION TIME

In their critique, Garfinkel, McLanahan, and Wallerstein raise concerns about the representativeness of the authors' sample, benchmark approach methodology, and historical review of guidelines, all of which lead them to discount the evidence presented opposing the cliff-model assumption of father expenditures on children, and to laud instead child support guidelines that give little monetary credit or adjustment for visitation. This article presents evidence that (a) this sample is at most little biased, and remains trustworthy for the main implications presented; (b) although only a beginning, the benchmark approach is highly useful and most of the concerns raised about it are ill founded or implausible; and (c) the historical review suggesting that current guidelines assume zero visitation expenses is indeed accurate for the vast majority of states, according to the foremost authority. Thus, notwithstanding the critique, these findings have merit and importance and should be considered by policy makers. The authors also comment on the additional arguments against continuous and generous adjustments for visitation, finding them based on a weak foundation of evidence and reasoning.     

Medication noncompliance in schizophrenia: codification and update

Risk of relapse and recidivism makes the failure to take antipsychotic medication as prescribed a significant issue in forensic psychiatry. This question may arise in such contexts as the setting of bail, plea bargaining, the insanity defense, and sentencing. We have reviewed the literature on medication noncompliance in schizophrenia and present here the results, organized by topics relevant for the work of forensic mental health experts. Reported rates of noncompliance vary widely, reflecting major differences in the populations studied and the methods used as well as the complexities involved in defining noncompliant behavior. A noncompliance rate of 50 percent has been attributed globally to chronic patients, both medical and psychiatric. The tendency of significant factors to interact precludes a simple typology of noncompliance. However, environmental security and supportiveness correlate positively with adherence; whereas anxiety, paranoia, grandiosity, depression, and side effects correlate negatively. Clinicians' assessments of whether medication is being taken have proven to be unreliable. Although monitoring by chemical measurement, particularly a radioreceptor assay for urine samples, can be useful, depot injection ensures that prescribed medication is being taken. Less invasive means of promoting compliance are described; psychodynamic and ethical issues to be considered in the monitoring and promotion of compliance over extended time periods are presented. We also probe the link between medication noncompliance and behavioral relapse. The time between default and relapse is most often measured in weeks. Whether due to medication withdrawal or not, the relapse pattern of each individual tends to repeat, allowing its recognition before recidivism occurs. Restarting medication at this stage, especially with a dosage increase, is usually effective. In sum, the forensic mental health expert can now readily use a large and diverse literature to assist with a variety of significant issues.

“Sex change” in skeletal remains: Assessing how heat-induced changes interfere with sex estimation

The true impact of heat-induced changes in human bone regarding their sex estimation has not been comprehensively documented having a potentially negative impact on forensic anthropology. The objective of this paper was to evaluate how heat exposure affects sex estimation based on both morphological and metric features. The study focused in both low-to-medium intensity burns and high intensity burns. Selected sexually dimorphic features were analysed in 51 experimentally burnt skeletons from the 21st Century Identified Skeletal Collection. Bones were burnt to maximum temperatures between 450 °C and 1050 °C achieved after 75 to 257 min. Morphological methods tested in this study comprised the recommendations for hipbone features from Buikstra and Ubelaker (1994) and from Bruzek (2002). On the other hand, metric references tested here were the ones from Wasterlain (2000), Curate et al. (2016) and Gonçalves et al. (2013) focused on the humerus, femur, calcaneus and talus. Agreement was tested with Gwet’s AC1 test and was further assessed by calculating the relative amount of perfect agreements. Results demonstrated that heat-induced changes affected not only the scoring of morphological features burnt at high temperatures but also the scoring of features burnt at lower intensities. On the other hand, metric features were only considerably affected in high intensity burns, no major changes being documented for low-to-medium intensity burns. For low-to-medium intensity burns, the Bruzek and Curate et al. methods revealed a better agreement between the pre- and post-burning scores. For high intensity burns, better agreement was obtained by using the Bruzek (2002) and Gonçalves et al. (2013) methods. As expected, heat-induced warping, fracture and metric change had a major impact on the pre- and post-observations’ agreement. Contrary to what has been systematically assumed over the years, this impact is also quite substantial in bones burnt at low-to-medium burn intensities so caution is advised during the analysis of this kind of burnt skeletal material.     

Citizen Participation in City Governance: Experiences From Vietnam

The radical political and economic reforms sweeping through former socialist countries during the last several decades have facilitated economic growth and urbanization. During this period of market reform and urbanization, citizen participation is greatly needed yet easily lost to other priorities. We employ stakeholder theory to examine whether citizen participation differs between large and small cities and between the poor and non‐poor people in Vietnam. Using data from a sample of citizens in five centrally managed cities, we found that citizens in large cities and citizens that belong to “unofficially poor” groups participate less. For policy makers, this implies that citizen participation should be of central importance in the management of current cities' expansions. In addition, the categorization of “poor households” needs to be closely monitored to minimize the risk of de facto poor households being excluded from the group.

Female serial killers in the United States: means,motives, and makings

Most studies that have focused on female serial killers (FSKs), although informative, have examined limited sample sizes. We consulted mass media reports of demographics, motives, methods, mental health, and victim characteristics of 64 FSKs who committed their crimes in the US from 1821 to 2008. Consistent with other studies, our data showed that FSKs were typically White, educated, have been married, and held a caregiving role (e.g. mother, health care worker). Nearly 40% of FSKs in this sample experienced some form of mental illness. Their most common motive for murder was financial gain, and their most common method of killing was poisoning. FSKs knew all or most of their victims, and most were related to their victims. In all cases, FSKs targeted at least one victim who was a child, elderly, or infirm – those who had little chance of fighting back. We interpret these killers’ behaviors from clinical and evolutionary angles.
