Time-lapse geophysical investigations over a simulated urban clandestine grave

A simulated clandestine shallow grave was created within a heterogeneous, made-ground, urban environment where a clothed, plastic resin, human skeleton, animal products, and physiological saline were placed in anatomically correct positions and re-covered to ground level. A series of repeat (time-lapse), near-surface geophysical surveys were undertaken: (1) prior to burial (to act as control), (2) 1 month, and (3) 3 months post-burial. A range of different geophysical techniques was employed including: bulk ground resistivity and conductivity, fluxgate gradiometry and high-frequency ground penetrating radar (GPR), soil magnetic susceptibility, electrical resistivity tomography (ERT), and self potential (SP). Bulk ground resistivity and SP proved optimal for initial grave location whilst ERT profiles and GPR horizontal "time-slices" showed the best spatial resolutions. Research suggests that in complex urban made-ground environments, initial resistivity surveys be collected before GPR and ERT follow-up surveys are collected over the identified geophysical anomalies.     

Further observations on the speed of death in hanging

Given that most fatal hangings are suicidal and occur in locations that have been selected to conceal this activity (thus maximizing the chances of a lethal outcome), there has been very little corroboration of the speed with which unconsciousness and death may occur. A 35-year-old male is reported who committed suicide by hanging immediately after talking to his spouse. Police investigations confirmed her reliability as a witness indicating that lethal anoxia in this case had occurred within a very short time (most likely in less than 1 min) of suspension. The speed with which death may result from hanging not only gives an insight into fatal pathophysiological mechanisms, but also provides useful information for situations where a lethal outcome is to be avoided, or is not intended. For example, individuals at risk of suicide who are being monitored in institutional facilities need to be constantly under direct visual surveillance as significant hypoxia can be rapidly induced, parents and caregivers with infants and children in potentially unsafe sleeping environments need to realize how swiftly death or irreversible anoxic brain damage may occur from neck compression, and those who engage in recreational asphyxia should be informed just how quickly a fatal outcome may ensue.     

The relationship between serial sexual murder and autoerotic asphyxiation

This case series documents and examines the association between autoerotic asphyxiation, sadomasochism, and serial sexual murderers. Autoerotic asphyxiation, along with other paraphilias found in this population, is reviewed. Five cases of serial sexual killers who engaged in autoerotic asphyxiation were identified worldwide: four from the United States and one from Russia. Case reports for each are provided. All (100%) were found to have sexual sadism in addition to autoerotic asphyxiation. Furthermore, two (40%) had bondage fetishism, and two (40%) had transvestic fetishism, consistent with these paraphilias co-occurring in those with autoerotic asphyxiation. Overall the group averaged 4.0 lifetime paraphilias. Some possible relationships were observed between the offenders' paraphilic orientation and their modus operandi, e.g., all of these serial killers strangled victims-suggesting an association between their sadistic and asphyxiative paraphilic interests. The overlap of seemingly polar opposite paraphilias in this sample--sexual sadism and autoerotic asphyxiation--is explored from a historical and clinical perspective. Multiple commonalities shared between these five offenders and serial sexual murderers in general are addressed. A primary limitation of this study is its small sample size and empirical basis; the results may not be generalizable beyond the sample. The findings from this study support the supposition that crime scene behaviors often reflect paraphilic disturbances in those who commit serial sexual homicides.     

Economic incentives for the self-regulation of the release of price-sensitive information

Companies, as primary disseminators of information, and financial institutions, as major recipients, have economic incentives to self-regulate the transmission and usage of price-sensitive information. These include increased (lost) reputation costs and adverse share price penalties arising from poor management of information disclosure. The economic motivation for self-regulation is seen as conceptually linked to but distinct from legislative changes. Self-regulation has the strong support of economic efficiency arguments, whereas recent additional new legislative changes do not. This article examines a major corporate and institutional response to the new regulatory climate—to internalize part of the regulatory process during their regular relationship communications. Relationships between the case companies and institutions already exist for transaction purposes. They are used as a convenient and low-cost means to pursue self-regulation and to avoid errors of price-sensitive information release. This self-regulatory process is illustrated using case material. It is clear from the response pattern presented that the development of a self-regulatory framework by the parties has been an iterative one. The corporate and institutional systems that have been evolving seem to be significantly influenced by the regulatory trends. The regulatory changes appear to have played a role in increasing market costs incurred by those companies with poor stock market communication practices. The article ends by arguing that new proposals to change in the formal regulatory system should recognize that further legislation is unlikely to improve the poor prosecution record. Nevertheless, legislative changes can combine with and buttress the self-regulation process to create an effective regulatory system.     

A new Fair Trade registration scheme based on the relations of production

Fashion, accessories, and homeware fall outside the regulations of Fairtrade Labelling Organizations International (FLO), which certifies mostly food products. A handful of fashion-led Fair Trade enterprises are now providing ranges of high-quality desirable products, made by workers employed in urban enterprises as well as independent producers in cooperatives. Tabeisa, an NGO involved in Fair Trade retailing, has developed a new regulatory framework which uniquely starts by defining the relations of production between all actors in the chain. This ensures that those not previously covered by existing standards are made visible and receive fair pay and conditions.

Nations hospitable to organized crime and terrorism

This report assesses conditions that contribute to or are potentially hospitable to transnational criminal activity and terrorist activity in selected regions of the world during the period 1999–2002. Although the focus of the report is on transnational activity, domestic criminal activity is recognized as a key foundation for transnational crime, especially as the forces of globalization intensify. The report has been arranged geographically into the following major headings: Africa, the former Soviet Union and Eastern Europe, South Asia, Southeast Asia, Western Europe, and the Western Hemisphere. Within the geographical headings, the report addresses individual countries with particularly salient conditions. Cases such as the Triborder Area (TBA) of South America and East and West Africa, where conditions largely overlap national borders, have been treated as regions rather than by imposing an artificial delineation by country. The bibliography has been divided into the same geographical headings as the text. The major sources for this report are recent periodical reports from Western and regional sources, Internet sites offering credible recent information, selected recent monographs, and personal communications with regional experts. Treatment of individual countries varies according to the extent and seriousness of conditions under study. Thus some countries in a region are not discussed, and others are discussed only from the perspective of one or two pertinent activities or conditions. Because they border the United States, Canada and Mexico have received especially extensive treatment.     

Identification of ascorbic acid and its degradation products in black powder substitutes

Low explosives such as smokeless powder, black powder, and black powder substitutes have been used in illicit pipe bombings throughout the United States. Some of the newer black powder substitutes are formulated with ascorbic acid, which gradually decomposes as the powder ages, making it difficult if not impossible for the forensic chemist to identify it by traditional bulk techniques. A sensitive method for the identification of residual levels of ascorbic acid in black powder substitutes is presented. Powder samples are extracted with a mixture of acetonitrile and bis(trimethylsilyl)acetamide (BSA), which converts carboxylic acid and alcohol functional groups to trimethylsilyl esters and ethers, respectively. Samples are then analyzed by gas chromatography-mass spectrometry (GC-MS). Results have shown that trace amounts of ascorbic acid can be identified at detection limits that are well below those for traditional bulk techniques. Degradation products for ascorbic acid (hydroxylated carboxylic acids, furanones, and lactones) can also be detected.
