Effect of hyperthermia on breath-alcohol analysis

Mild hyperthermia to the extent of a 2.5 degrees C increase above normal body temperature was produced by immersion of ethanol-intoxicated subjects in a warm water bath. Hyperthermia did not influence the blood-alcohol decay curve of the subjects. Hyperthermia did cause a significant distortion of the breath-alcohol decay curve, up to as much as a 23% increase above blood-alcohol concentration. The magnitude of this distortion effect was calculated to be a 8.62% increase in breath-alcohol concentration over blood-alcohol concentration for each degree C increase in core body temperature. The forensic relevance of these results is that further support is given to previous recommendations that temperature monitoring be included in procedures for breath-alcohol analysis. This leads to the recommendation that mouth temperature be measured before breath sampling to screen for abnormal body temperature and to allow for potential use of a "temperature correction factor." This modification to existing analytical procedures would optimize the reliability of breath-ethanol analysis for prediction of blood-ethanol concentration.     

Race/Ethnic-Specific Homicide Rates in New York City: Evaluating the Impact of Broken Windows Policing and Crack Cocaine Markets

The current study evaluated a range of social influences including misdemeanor arrests, drug arrests, cocaine consumption, alcohol consumption, firearm availability, and incarceration that may be associated with changes in gun-related homicides by racial/ethnic group in New York City (NYC) from 1990 to 1999. Using police precincts as the unit of analysis, we used cross-sectional, time series data to examine changes in Black, White, and Hispanic homicides, separately. Bayesian hierarchical models with a spatial error term indicated that an increase in cocaine consumption was associated with an increase in Black homicides. An increase in firearm availability was associated with an increase in Hispanic homicides. Last, there were no significant predictors for White homicides. Support was found for the crack cocaine hypotheses but not for the broken windows hypothesis. Examining racially/ethnically disaggregated data can shed light on group-sensitive mechanisms that may explain changes in homicide over time.     

Societal openness during the urban crisis. Partner selection in the 19th-century Belgian textile cities Ghent and Verviers

This paper examines the partner selection of the lower classes during an urban crisis period in early industrial Belgian cities. It was found that in this period characterized by an economic transition, overpopulation, migration and a low standard of living, social heterogamy was high, whereas social homogamy increased, or was ‘restored’, in the subsequent period. The urban crisis effect on partner selection contradicts the claims of modernization theory that there was a gradual increase in societal openness and that societal openness was typically modern, but it fits the idea of the informalization of marriage, a process marked by an increase in unmarried cohabitation and illegitimacy.

Relationships between the deinstitutionalization of healthcare for patients with mental disorder, substance abuse, and isolated death

Isolated death (ID) (i.e., dying alone without anyone noticing for several days) has been suggested to be related to social isolation, mental disorder, and alcohol and/or drug abuse. A major transfer of patients with a mental disorder and/or alcohol and/or drug abuse from institutionalized care to treatment as outpatients has been enacted in Sweden during the past decade. On the basis of the assumption that such deinstitutionalization is likely to result in increased social isolation, our working hypothesis was that the incidence of ID among patients belonging to these categories has increased in Sweden. The present study involved all deaths subjected to a medicolegal examination in Stockholm County (with a population of approximately 1.9 million people) during the period 1992-2000. The pattern of ID (defined as cases involving a postmortem delay between death and discovery of at least 1 week), as well as the incidence of fatalities subjected to medicolegal examination with a record of mental disorder and/or alcohol and/or drug abuse was evaluated. Throughout this period, the proportion of the deceased with a record of a mental disorder was high among all the cases examined and higher still among the cases of ID, especially among those younger than 65 years of age. There was a rather limited increase in the incidence of ID and a much more pronounced increase in the number of former psychiatric patients whose deaths were subjected to medicolegal examination, but did not satisfy the criteria for ID. A record of alcohol and/or drug abuse was more common than a diagnosis of mental disorder among both the males and females who died at an age of less than 65, with a clear difference between the cases of ID and non-ID in the case of men. There was no significant increase in incidence over the course of this study. Thus, this study reveals a slight increase in the number of IDs and a more pronounced increase in the number of medicolegal examination of non-IDs of individuals with a record of a mental disorder.     

Criminalization Against Traffic Offenders in Japan

Japan experienced rapid motorization, which was followed by an increase of traffic accidents. However, the increase was suppressed around 1970. Criminalization against traffic offenders may have contributed to it. The process of criminalization may be instructive to other countries suffering from an increase of traffic accidents. But in Japan we should realize the limit of criminalization and check further criminalization.     

Promoting the Safe and Strategic Use of Technology for Victims of Intimate Partner Violence: Evaluation of the Technology Safety Project

The Technology Safety Project of the Washington State Coalition Against Domestic Violence was designed to increase awareness and knowledge of technology safety issues for domestic violence victims, survivors, and advocacy staff. The project used a “train the trainer” model and provided computer and Internet resources to domestic violence service providers in order to (1) increase safe computer and Internet access for domestic violence survivors in Washington; (2) reduce the risk posed by abusers by educating survivors about technology safety and privacy; and (3) increase the ability of survivors to help themselves and their children through information technology. Evaluation of the project suggests that the program is needed, useful, and effective. Consumer satisfaction was high and there was perceived improvement in computer confidence and knowledge of computer safety. Areas for future program development and further research are discussed.     

A potential metallographic technique for the investigation of pipe bombings

This study was conducted in an attempt to develop a metallographic method for the investigation of pipe bombings. Three common pipe materials, ASTM A53 steel, AISI 304L stainless steel, and 6061-T6 aluminum, were shock-loaded using five high explosives and three propellants. The explosives used were ANFO, Composition C4, C6 detasheet, nitroglycerine-based dynamite, and flake TNT. The propellants used were FFFFg black powder. Red Dot smokeless powder, and Turbo Fuel A. The post-blast microstructure, hardness, and, in the case of 304L, transformed martensite content were examined for each test. The damage done to the microstructure was found to increase with increasing detonation velocity of the explosives and increase in pressure generated by the shock-metal interaction. Material hardness and, in the case of 304L, martensite content showed a sharp increase followed by a plateau as the shock pressure and detonation velocity increased.     

The failure of effective technological transfer in Polish industry

Central planners in Poland have continuously emphasized the importance of increasing factor productivity as a major goal of Polish development policy and have included this goal as an integral part of every economic reform proposal of the last two decades. In the decade of the 1970s a new development strategy was initiated which counted heavily on the import of more technologically advanced machinery and equipment and the purchase of licenses and production processes from the West. This paper documents the tremendous increase in Western imports and the purchase of licenses which took place in the 1970s, and which would then be expected to generate an increase in joint factor productivity due to technological change. Empirical analysis, however, indicates that there was no effective transfer of the technology. Joint factor productivity for total industry calculated as a residual in estimated production functions, which include imported inputs, has a zero rate of growth from 1970 to 1978 (using quarterly data). Disaggregating and using annual data over a longer sample period yields estimates of the rate of growth of joint factor productivity which increase slightly for total industry in the 1973–1977 period. For the electrical and mechanical branch which received large numbers of license and joint production agreements the rate of growth of joint factor productivity remained unchanged. The results indicate that systemic factors such as central planning, managerial inhibitions and supply bottlenecks out-weighed any potential increase in factor productivity as a result of technology transfer.     

Effect that the relative abundance of copper oxide and zinc oxide corrosion has on the visualization of fingerprints formed from fingerprint sweat corrosion of brass

From an examination of the fingerprint sweat corrosion of 40 different individuals on α phase brass, we show that an increase in visualization can be achieved by applying a negative potential to the brass followed by the introduction of a conducting powder. Previously, this technique has been demonstrated only for a positive applied potential and a corrosion product that was dominated by p-type copper (I) oxide. X-ray photoelectron and Auger electron spectroscopic analyses of the surface of the corroded brass show that an increase in visualization with a negative applied potential corresponds with an increase in the concentration of n-type zinc oxide relative to p-type copper (I) oxide with the Cu:Zn ratio <0.8:1. Work function conditions for the formation of an n-type zinc oxide/brass rectifying Schottky barrier are fulfilled.     

Myocardial hypertrophy induces carotid body hyperplasia

The carotid bodies tend to enlarge after long-standing cardiopulmonary disease. Our objective was to investigate whether cardiac hypertrophy is associated with carotid body hyperplasia. Fifteen autopsy cases with combined left and right ventricular hypertrophy were examined and compared with two control groups (16 cases). The study involved a meticulous dissection of carotid bifurcations, thin serial sections, and morphometric analysis of carotid body volume and cell types (progenitor, dark, light, and sustentacular). There was a significant increase in sustentacular cells in all individuals with cardiac hypertrophy, which was not drug-induced, and accompanied by a similar increase in carotid body volume. Dark or light cell accumulation was detected focally and only in three instances. It appears that the generalized sustentacular cell hyperplasia is the result of long-standing hypoxia, while a superimposed focal prominence of dark or light cells may be proliferative or metaplastic in nature and attributed to short-term hypoxia.     

In vivo facial tissue depth measurements for white British children

This paper reports the results of a study of facial tissue depth measurement in White British children of both sexes, aged between 11 and 18 years. The purpose of this research was to increase the information available upon tissue depth data for children, primarily for use in forensic facial reconstruction. Facial tissue depths were measured at 21 anatomical points using ultrasonic echo-location. The mid-philtral, upper lip border and lower lip border points showed consistently larger tissue depths in the males than the females, and the zygomatic attachment showed consistently larger tissue depths in the females than the males. The males showed a general increase in tissue depth with an increase in age at all the mid-line facial points and the cheek points. The females showed increased tissue depth with age at all the points except the infra-orbital, lateral orbital, mid-zygomatic arch and mid-mandibular points. A table of mean tissue depths was developed for males and females divided into two-yearly age groups.     

Population Size,Age Structure,and Sex Composition Effects on Official Crime in Canada

Canada, along with most other Western, industrialized countries, has experienced a dramatic increase in both the overall volume and the rate of official crime, as well as significant increases in the amount of female crime since the mid-1950's. Several authors have suggested that much of this increase in official crime is related to major demographic fluctuations, such as the post-war “baby-boom.” Specifically, in this paper it is maintained that a large proportion of the increase in the overall amount of crime is due to both absolute as well as relative increases in those segments of the population which have high a priori crime rates.

Using 1957 as a base year, the volume of convictions for criminal offenders in Canada is standardized for population size, age structure, and sex composition effects. It was found that approximately one-half of the increase in volume of crime could be attributed to overall population growth. The impact of age structure and sex composition was not unambiguous, however, with the period 1958–1964 showing a greater sensitivity to these variables than the period 1965–1973.     

LinkedLegal: Investigating social media as evidence in courtrooms

The pervasive nature of social media suggests it would increasingly appear as evidence in the courtroom as it has increasingly documented daily life. This research examines the use of such evidence through the review of appellate judgments. It has identified 5,189 appeal cases in federal and state jurisdictions for the period from 1 October 2000 to 30 September 2017. California was used for the state jurisdictional analysis and the Ninth Circuit Court of Appeals, which includes California, was used for the federal. In 2017, there was a 350% increase in Ninth Circuit cases using social media evidence as compared to the first cases in 2010. There was a 3933% increase in the California state cases from the first cases in 2007. Photos/images evidence were used the most in State criminal cases and all Federal cases, while posts evidence was used the most in State civil cases.     

Waste not, want not—A look at the impact of manufacturing extension centers

Manufacturing extension centers have helped small manufacturers improve performance on the shop floor and thereby reduce costs. This article presents a case study of a metal working firm that was able to increase productivity and profits by instituting measures recommended by a field agent working for the Florida Manufacturing Technology Center (FMTC). As a result of services provided, the company was able to boost manufacturing throughput and increase production efficiencies. Using a simulation model, the article explores how small changes in manufacturing performance can result in significant cost reduction. It then discusses the consequences of alternative strategies designed to enhance the value of goods sold, rather than lower the costs of production. It concludes by arguing that manufacturing extension centers should help companies become more distinctive as well as more efficient.     

Cocaine in Wayne County Medical Examiner's cases

We determined the incidence of detection of cocaine or its metabolites in Wayne County (Michigan) Medical Examiner's cases from 1984 to 1987. Over this four-year period there was a significant (P less than 0.01) increase each year in evidence of recent cocaine use in this population, reaching 38.3% of all tested cases in 1987. Much of this increase was accounted for by homicide victims, especially those in their third or fourth decade of life, of whom 58.6 and 56.3%, respectively, tested positive in 1987. There was a large increase in recent cocaine use in teenage homicide victims in 1987, having previously changed little from 1984 to 1986. In victims of drug abuse, recent cocaine use also increased significantly (p less than 0.01) each year, reaching 47.6% in 1987, generally in combination with heroin. Although deaths attributed solely to cocaine were not as common, they also increased significantly each year from 4 in 1984 to 25 in 1987. Compared with the general population, those who use cocaine in Wayne County are more likely than those who do not to die prematurely, often as a result of violence.     

Research of the extraction method of morphine from biological fluids

A solid-phase extraction method of morphine from urine and blood has introduced. The effect of 5 SPE columns, 3 eluents and pH on morphine recovery has been investigated systematically. Derivative GC was used as a method of detection. The result showed that the column and the eluent of such as GDX-301, GDX-403 and C18 chloroform:isopropanol (9:1) had good behaviors to extraction of morphine. When GDX-301 was used as a sorbent, the recovery of morphine from urine was above 90% at pH 9, then went down with the increase of pH. While the recovery from blood was growing with the increase of pH, which reached above 90% in strong alkaline. The extraction method is simple, inexpensive, efficient and reproducible, which provides an effective and practical method to extract morphine and similar illicit drugs from biological fluids.     

A comparison of the length and width of static inked two-dimensional bare footprints found on a hard compared to a soft surface

In forensic intelligence-gathering it would be useful to evaluate if there are differences between static inked bare footprints captured on hard surfaces compared to soft surfaces. This was undertaken using samples from 30 undergraduate students. Initially a static footprint was taken for each participant on a hard surface and this was followed by a static footprint on a soft surface. On both occasions, the participants stood on an inkless mat and then on reactive paper, creating a two-dimensional print. The Reel method was used to analyse each footprint and the print was measured to see whether a difference existed between length and width (forefoot and rearfoot width) on a hard surface compared to a soft surface. The conclusion from this study was there is a statistically significant increase in length and width of a static bare footprint on a soft surface as opposed to a hard surface. If a forensic footprint examiner compares static bare footprints found on a soft surface and compares them to a static bare footprint of the same foot taken later, then the increase in both length and width of the footprints on a soft surface should be considered in the evaluation.     

The impact of public policy and publicity on admissions to state mental health hospitals

This paper examines the impact of broadened Washington state civil commitment standards on utilization of the state's mental hospitals. Included in the analysis is an assessment of the impact of a public event (a well-publicized murder case) which was in all likelihood a precursor to the law's revision. We also examine the different ways Washington's two state hospitals managed the dramatic increase in civilly committed patients that occurred after the revision took effect. The findings indicate that the murder case, in which the defendant had been denied voluntary admission to a state hospital prior to the killing, resulted in an increase in involuntary admissions in the county where it occurred a full year before the standards were revised. The law itself had the effect of increasing commitments throughout the state, reducing the levels of voluntary admissions, and increasing the likelihood of involuntary admission for individuals previously admitted voluntarily, thus transforming a principally voluntary system into one which was primarily involuntary. Finally, it was found that the increased demand for services mandated by the broadened commitment standards was managed differently in the two state hospitals: one imposed a cap on admissions; the other phased out voluntary admissions at a rate roughly equal to the increase in commitments. These findings illustrate both the substantive impact of broadened civil commitment law and the importance, when assessing the impact of laws, of examining public events and administrative interventions which may have significant causal links with legal interventions.
