The author presents the case that the study of migration over the past century has become too diverse. He reviews works by writers from the several disciplines covering the topic, then cites the need to develop a consistent classification of the types of migration and their origins using standardized terminology.

The relationship between ethanol and risk of heroin overdosage was studied. Statistical processing of the results of forensic chemical analysis (460 expert evaluations) carried out in Chelyabinsk Regional Bureau of Forensic Medical Expert Evaluations in 2000 was carried out. The results of morphine and ethanol measurements in the blood and urine from corpses where deaths ensued from narcotic or ethanol poisoning, were analyzed. The concentrations of morphine in the blood and urine were measured on a gaseous chromatographer with mass-selective detector (Hewlett Packard HP 6890/HP-5972). Methods for measuring urinary and blood morphine are described. The results of statistical analysis demonstrated relationships between the age and ethanol concentrations in the blood and urine; blood ethanol and total urinary and blood morphine concentrations; blood concentration of free morphine and presence of 6-monoacetylmorphine in the blood. The authors conclude that the presence of ethanol in the blood together with morphine drastically augments the risk of rapid death from respiration arrest. It can also lead to a relatively high risk of overdosage in experienced narcomaniacs using heroin and ethanol. 相似文献

The 11 Y-chromosomal short tandem repeats (STRs) included in the Promega Corporation PowerPlex Y System (DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS385, DYS437, DYS438 and DYS439) were typed in three ethnic groups ("Andalusians", Berber and Arab) and one cosmopolitan population (Tunis) from Tunisia, summing up 247 individuals, and 139 different haplotypes. Focusing the analysis on the seven Y-STRs of the YHRD Minimal Haplotype Core (DYS385 excepted), "Andalusians" showed no differences from the Cosmopolitan and the Arab samples previously published (our Arab sample presented an extremely low haplotype diversity), but were different from the Berbers. The Berbers from Tunisia were not different from those from Morocco. 相似文献

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. 相似文献

Different-distance experimental shots were made from a rifled gun at flat bones. Those shot distances were established, at which the wound canal had the smallest volume, and, at which entry and exit holes were virtually identical and matched the bullet diameter. A bigger shot distance was associated with an increasing volume of the wound canal caused by a bigger exit hole. A smaller shot distance led, also, to an increasing volume of the wound canal caused by bigger entry and exit holes. The volume of the wound canal in flat bones can be used as a reliable criterion in assessing the shot distance. 相似文献
