Literacy comes second: working with groups in developing societies

The ?Literacy comes second? model is an experimental approach that may hold greater promise for the future than the traditional literacy classes. The model works with groups that already exist within the community, such as religious groups, groups meeting for business, residents? groups (especially in urban areas), local government and political groups. The main characteristic of these groups is that, from the point of view of literacy, they are mixed groups consisting of men and women who have different levels of literacy skills. The group members share their skills and experiences; thus every member is valued. The justification for the approach comes from an adult learning theory, which states that adults learn best through doing things in their own lives for real. In general, the goal for this approach is that people will learn how to read and write and use literacy skills to achieve developmental tasks.     

Distribution of morphine and morphine glucuronides in body tissue and fluids--postmortem findings in brief survival

An intoxication following administration of morphine, tramadol and atracurium in a suicide case is reported. The route of administration and the amount of the particular drug were known from the investigation of the death scene and the findings of the postmortem examination. Tramadol was present in the gastric contents as well as in blood, liver, kidney and brain samples, whereas the drug could not be detected in muscle. All body fluids and tissues investigated contained morphine as well as its 3- and 6-glucuronides with the exception of muscle tissue. The concentrations of morphine and its glucuronide metabolites were determined by LC/MS following solid phase extraction. Interestingly, the concentration of M6G in brain, liver and kidney were close to the concentration of M3G in the particular tissue. This phenomenon might be explained by a preferential hydrolysis of M3G or by a preferential formation of M6G postmortem. Measurement of morphine and M6G in femoral blood and cerebrospinal fluid may be a useful indicator in rapid deaths.     

Solving an "appalling" problem: social reformers and the campaign for the Alberta Sexual Sterilization Act, 1928

In this article, the author examines the campaign leading up to the passage of the Sexual Sterilization Act in Alberta in 1928. The author asserts that the passage of this Act was the result of the influence of a few elite individuals, particularly those involved with the United Farm Women of Alberta social reform movement, and may not have been reflective of widespread favourable public sentiment. While there were serious misgivings regarding the passage of the Sexual Sterilization Act, the legislation was ultimately successful because of the pressing problems of inadequate mental facilities and budgetary constraints. The author discusses the legislation's eventual repeal in 1972 due to public denunciation of eugenic measures, concerns about liability, and the threat posed to individual liberties. This article was the winner of the William Morrow Essay Contest in 1999.     

Physical and chemical evidence remaining after the explosion of large improvised bombs. Part 1: firings of ammonium nitrate/sugar and urea nitrate

Recent criminal acts in the United Kingdom, United States and other countries have demonstrated the dangers to public safety from the criminal use of improvised explosives on a large scale. Four sets of trials were carried out over four years, partly in collaboration with the United States Federal Bureau of Investigation, involving the firing of large bombs, mostly fertilizer based. The principal objectives of the firings were to measure the physical effects of the explosions upon objects representative of those that would be found at a real bomb scene and to recover any chemical traces deposited on these objects. The results are intended for use as an aid in determining the approximate size and type of an explosive employed in a terrorist attack. This paper describes the background behind the trials, the procedures for preparation of witness materials and charges, and the collection and analysis of physical and chemical evidence.     

The FAA's postmortem forensic toxicology self-evaluated proficiency test program: the first seven years

Existing proficiency-testing (PT) programs do not address the complexity of postmortem forensic toxicology. These programs do not include decomposed samples and solid tissues. Therefore, the Federal Aviation Administration in July 1991 started such a needed PT program. This program is used to: (i) professionally develop and maintain technical currency on a voluntary, interlaboratory, and self-evaluation basis, and (ii) quantifiably assess methods in the absence and presence of interfering substances. There are currently about 30 laboratories in the program. Functioning under various governmental/non-governmental agencies and academic institutions, these laboratories represent a broad cross-section of the country. PT samples are distributed quarterly, and result summaries are sent to the participants, while maintaining their anonymity. Since the inception of the program, 28 PT samples encompassing whole blood, plasma, urine, kidney, or liver, with (or without) drugs, metabolites, and common chemicals (nicotine, caffeine, beta-phenylethylamine, etc.) have been analyzed by the participants. Analytical findings were generally consistent with the anticipated values, but they were dependent on the nature and conditions of the specimens and types of the added analytes. Some incidences of false positives of concern were noted, as well. This PT program is one of the few programs recommended by the American Board of Forensic Toxicology in which laboratories may participate for their accreditation by the Board. It is anticipated that this PT program will continue to play a critical part in supporting the quality assurance/quality control (QA/QC) component of forensic toxicology, thereby enhancing operational performance.
