Migration as a Tool in Development Policy: Caution Ahead?

The World Bank and UNDP have proposed that migration and mobility facilitate economic development. Yet the epidemiological and public health literature has often associated migration and population mobility with the extension and intensification of infectious diseases, most recently epitomised by the AIDS pandemic. Within the context of the well-documented negative developmental impact of AIDS, this suggests a potential clash in perspectives on the role of migration. However, if insights from public health can be incorporated into broader development perspectives, it may be possible to realise the developmental benefits of migration while mitigating or avoiding any associated health concerns.     

The Differentiation of Menstrual from Venous Blood and Other Body Fluids on Various Substrates Using ATR FT‐IR Spectroscopy

Crime scene investigators and laboratory analysts use chemical tests to detect and differentiate body fluids. Testing often requires a sample of the stain, and the chemicals may cause degradation of the fluid or interfere with subsequent tests. Colorimetric chemical tests do not differentiate between different types of the same fluid, such as venous and menstrual blood, and there is no presumptive test available to simultaneously differentiate several body fluids. In this study, we recorded ATR FT ‐IR spectra of venous and menstrual blood, semen, saliva, and breastmilk. Neat and simulated casework body fluid samples were analyzed on cotton, nylon, wood, paper, and glass substrates. Differences in fluid composition, including proteins and small molecules, resulted in spectral differences. Venous and menstrual blood is differentiated by the peak at 1039 cm^?1 attributed to phosphoric acid found in menstrual blood. Peak intensity is influenced by the porosity and weave of the substrate fabric.     

The front and back stages of carceral expansion marketing in Canada

This article examines how provincial and territorial government agencies and prison authorities in Canada promote new penal infrastructure initiatives. Through an analysis of press releases, websites, opening ceremonies and open houses to promote jail and prison construction projects, our analysis reveals discourses that are legitimating carceral expansion in the Canadian context including: the pursuit of public safety and institutional security; providing opportunities for rehabilitation and healing; addressing the legacies of colonization through the ‘indigenizing’ of imprisonment; generating economic stimulus through prison-related employment and other financial contributions; and the establishment of ‘environmentally-friendly’ prisons. Drawing from government records obtained using Access to Information and Freedom of Information requests, we also provide examples of how front stage messages communicated to the public are assembled by bureaucrats and marketing firms in the back stage of these punishment campaigns.     

Fentanyl concentrations in 23 postmortem cases from the hennepin county medical examiner's office

The purpose of this study was to compare blood fentanyl concentrations in fentanyl-related deaths with fentanyl concentrations found incidentally at autopsy, as well as with fentanyl concentrations found in hospitalized patients receiving fentanyl. Between the years 1997 to 2005, 23 fentanyl-positive postmortem cases were identified. Nineteen of 23 (82.6%) cases were deemed to be drug overdoses. Fentanyl alone was responsible for 8 of the 19 (42.1%) overdose deaths. Mean and median fentanyl concentrations were 36 (SD 38) microg/L and 22 microg/L, respectively, range 5-120 microg/L. Seven of the cases were accidental, one undetermined. The remaining 11 of the 19 (57.9%) cases were mixed drug overdoses. Fentanyl concentrations in these cases were 31 (SD 46) microg/L, range 5-152 microg/L. All of the mixed drug overdoses were determined to be accidental. Four cases where fentanyl was considered an incidental postmortem finding were determined to be natural deaths. In hospitalized inpatients (n = 11) receiving fentanyl 2 of the patients receiving fentanyl for chronic pain for more than 3 months had concentrations of 8.5 microg/L and 9.9 microg/L. The other nine inpatient concentrations were less than 4 microg/L. In conclusion, blood fentanyl concentrations found in cases where fentanyl alone was determined to be the cause of death were similar to cases where fentanyl was part of a mixed drug overdose. There was also considerable overlap between fentanyl concentrations in fentanyl-related overdose deaths compared to hospitalized patients being treated for chronic pain. Fentanyl concentrations in postmortem cases must be interpreted in the context of the deceased's past medical history and autopsy findings.

Bone Mineral Density Adult Age Estimation in Forensic Anthropology: A Test of the DXAGE Application

Estimating age‐at‐death of individuals represented only by skeletonized human remains is a fundamental aspect of forensic anthropological casework. Recently, several researchers have proposed that bone mineral density (BMD) is a useful predictor of age‐at‐death in forensic contexts. Navega et al. (JFS 63(2):497–503) developed an online application called DXAGE for calculating age‐at‐death from BMD parameters. This study tests the utility of DXAGE by utilizing data from the National Health and Nutrition Examination Survey (NHANES). BMD data from a female subsample (n = 470) of the NHANES 2007–2008 dataset were analyzed, and the relationship between predicted age and real age was examined. Inaccuracy was 14.25 years, and bias was ?7.20 years. Results show that there is a weak correlation between predicted and actual age (r = 0.47) using the DXAGE application. While BMD data are potentially useful for predicting age age‐at‐death, the DXAGE application should be used cautiously in forensic anthropological contexts.     

Cases of Kava Impairment in Iowa Drivers

Kava is an Oceanic plant in which the root is consumed as a beverage and is becoming increasingly popular. The effects of kava consumption may include sedation, euphoria, and impairment of motor coordination. This article demonstrates kava impairment through four cases of self‐reported kava use supported with Drug Recognition Expert (DRE) evaluations of each subject. Subject's urines screened negative for common drugs of abuse by immunoassay analysis. Urine from cases 3 and 4 were analyzed by liquid chromatography–tandem mass spectrometry, and gas chromatography–mass spectrometry, which yielded the presence of kavalactones. Subjects exhibited poor driving behavior and signs of intoxication. Indicators of impairment from multiple drug categories, central nervous system (CNS) depressants, CNS stimulants, and cannabis were observed, which may be consistent with the presence of multiple kavalactones and their diverse array of mechanisms of action. The consumption of kava can hinder one's ability to operate a vehicle safely.     

Criminal Records and Employment: A Survey of Experiences and Attitudes in the United States

Ban-the-Box (BTB) legislation, which bans employers from asking about criminal history records on the initial job application, is arguably the most prominent policy arising from the prisoner reentry movement. BTB policies assume: 1) most employers ask about criminal records, and 2) inquiries occur at the application stage. However, we lack reliable information about the validity of these assumptions or about public attitudes towards criminal background checks, which limits our understanding of the potential scope of this innovative policy. Using survey data from a national probability sample, we estimate that in the past year, over 31 million U.S. adults were asked about a criminal record on a job application. According to our survey, virtually all of the criminal record inquiries occurred at the application stage, highlighting the potential of BTB. However, we also found that the public is sharply divided on whether to prevent employers from asking on applications, as per BTB.     

The Extent and Correlates of Public Support for Deterrence Reforms and Hot Spots Policing

As one approach to prison downsizing and criminal justice reform, scholars recommend altering the nature of policing by reallocating resources toward policing and increasing sentinel patrols and hot spots interventions. Public attitudes toward these reforms are unknown. In the current police crisis, shifting policies in ways disfavored by the public can impact police‐community relations, especially among those disproportionately affected. The current study uses survey data from a nationally representative sample of Americans to evaluate whether the public is receptive to the suggested reforms. Our results indicate that the majority of the general public believes policing is more cost‐effective than incarceration and supports a focus on sentinel patrols and crime hot spots, although there is less support for hot spots policing among blacks, Hispanics, and lower income individuals. The hot spots policing strategy most preferred is situational prevention, and the least supported is aggressive order‐maintenance policing.
