Non‐English‐speaking people do not always seek medical care through established institutions. This paper reports a series of deaths in unlicensed alcohol rehabilitation facilities serving Spanish‐speaking men. These facilities are informal groups of alcohol abusing men who live together. New members receive various treatments, including administration of ethanol or isopropanol, restraint, and seclusion. We reviewed 42 deaths in unlicensed alcohol rehabilitation facilities in Los Angeles County during the years 2003–2014. Data gathered included age, length of time spent in the facility, blood alcohol and drugs at autopsy, and cause and manner of death. Causes of death included acute alcohol poisoning, alcohol withdrawal, and a variety of other causes. Three cases were considered homicides from restraint asphyxia. The Department of Medical Examiner‐Coroner has worked with the police, district attorney, and State Department of Health Services to try to prevent additional deaths in unlicensed alcohol rehabilitation facilities. Nevertheless, prevention has been difficult. 相似文献

The Philadelphia Low-Intensity Community Supervision Experiment provides evidence on the effects of lowering the intensity
of community supervision with low-risk offenders in an urban, US county community corrections agency. Using a random forests
forecasting model for serious crime based on Berk et al. Journal of the Royal Statistical Society, Series A, 172(Part 1), 191–211, 2009, 1,559 low-risk offenders were identified and randomly assigned to either standard or reduced frequency of mandatory office
visits. Treatment as assigned was substantially delivered at 4.5 probation visits per year versus 2.4, for as long as offenders
remained on active probation or parole. In a one-year follow-up for all cases, outcomes examined were the prevalence, frequency,
seriousness and time-to-failure of arrests for new crimes committed after random assignment was implemented. No significant
differences (p = .05) in outcomes were found between standard and low-intensity groups. Non-significant differences for offense seriousness
favored the low-intensity group. We conclude that lower-intensity supervision at the tested level of dosage can allow fewer
officers to supervise low-risk offenders in the community without evidence of increased volume or seriousness of crime. 相似文献

Abstract: There have been few documented comparisons of serial murder cases committed in the United States with cases occurring internationally. The authors contrasted two unique serial murder series: one in Italy and one in the United States by examining the details of both series, including the M.O., motivation, crime scene interactions, sexual acts performed, and the general backgrounds of both offenders. The comparison revealed a number of similarities. Both offenders specifically targeted elderly women, who were attacked in their residences. The two series involved sexually motivated crimes, although the sexual interactions were different. Both offenders stole objects from their victims after the murders and each kept newspaper accounts of their crimes. In addition, both offenders claimed to have abusive upbringings, including sexual abuse. 相似文献

Objectives
Conventional statistical modeling in criminology assumes proper model specification. Very strong and unrebutted criticisms have existed for decades. Some respond that although the criticisms are correct, there is for observational data no alternative. In this paper, we provide an alternative.Methods
We draw on work in econometrics and statistics from several decades ago, updated with the most recent thinking to provide a way to properly work with misspecified models.Results
We show how asymptotically, unbiased regression estimates can be obtained along with valid standard errors. Conventional statistical inference can follow.Conclusions
If one is prepared to work with explicit approximations of a “true” model, defensible analyses can be obtained. The alternative is working with models about which all of the usual criticisms hold.606.
An unidentified white powder collected as evidence in an intelligence investigation was characterized exclusively by nuclear magnetic resonance (NMR) analysis. A small fraction of the powder dissolved in D2O was subjected to a series of one- and two-dimensional techniques which were used to elucidate the molecular structure of the powder's major component and positively identify it as the scopolamine biotoxin. Quantitative one-dimensional experiments identified individual proton and carbon atom sites, and conventional 14N spectroscopy detected a single nitrogen atom site. Heteronuclear single quantum coherence data correlated all protons to their directly bonded carbon atom, and together with the quantitative spectra, were used to determine the number of protons directly bonded to each carbon atom. The presence of a methyl, carboxyl, and a benzyl group was also identified from these data. Correlation spectroscopy detected a three proton and a nine proton JH,H network, representing a CH2CH moiety and seven carbon atom ring, respectively. These five elements were assembled into an almost complete molecular structure by using long-range, J-coupled, 1H-13C pairs detected by heteronuclear multiple bond correlation (HMBC) spectroscopy and 1H-1H dipolar-coupled pairs found from nuclear Overhauser effect spectroscopy (NOESY) data. Additional oxygen atom sites were inferred from 1H-13C correlation intensities in the HMBC spectra along with 1H and 13C chemical shift values, or directly from NOESY correlations. Only a single oxygen atom site could not be inferred from NMR data, but its presence was inferred from comparisons to target analyte structures to complete the structure of the scopolamine molecule. To confirm these results, an ethanol/H2O solution of the powder was analyzed by direct infusion into an ion trap mass spectrometer. A prominent base signal was observed at m/z 304.1 amu, corresponding to the protonated molecular ion of scopolamine. Subsequently, the ion was selected and subjected to collision-induced dissociation, producing characteristic major MS/MS fragments at m/z 138.1 and 156.1. Comparisons of 1H and 13C chemical shift values and JH,H values measured from our NMR data were found to agree very favorably with previously reported values for scopolamine in D2O. 相似文献

Given the impediments around them, can welfare recipients be required to work? Most analysts have answered no. They say the recipients are usually kept from employment by socioeconomic barriers, such as insufficient jobs, and the disincentives to work inherent in welfare. Studies of recent AFDC work programs make them look promising but do not directly address the potential for work enforcement. This article, a cross-sectional study of state WIN programs in 1979, suggests that work requirements could raise work levels substantially despite the impediments. But requirements probably do not improve the quality of jobs recipients are able to get. Therefore, enforcement serves the goal of integration, but to achieve greater economic equality will require additional reforms. 相似文献
