The index of lethal poisoning with ethyl alcohol and its surrogates in Russia remains one of the highest in the world. It is explained by high alcohol consumption in Russia (about 15 liters of pure alcohol per capita annually), consumption of mainly strong beverages (about 80%), extensive sales of adulterated strong alcoholic beverages (more than 25%), virtually no preventive work in the population, and other causes. The index of lethal poisoning with alcohol and its surrogates in the country and its regions is one of the most important parameters in evaluation of the socioeconomic well-being of the population. 相似文献

Studies of college freshmen find that men are more sexist in their attitudes than women. Does this hold also for high school students? This paper reports the relationship of (1) sex-role attitudes to selected school and family characteristics and (2) attitudes toward family life to sex-role conceptions for women and men. The study is based on 529 students in grades 9 to 12 attending four high schools. The findings show that males are more sexist than females and Blacks more so than Whites. Women who are bright, from upper class backgrounds, and whose mothers work are more equalitarian in sex-role conceptions. For men, family background is unimportant, but attending an elite public school seems to foster equalitarian sex-role conceptions. Men's sex-role attitudes are harder to explain than women's, and, unlike women, their role attitudes have little connection to their family orientation. 相似文献

The chemical substances of perspiration found in latent fingerprint residue may hold the key for dating latent fingerprints. To study the chemical transformations of these components as a function of time and environment, fingerprint residues from four males and four females were analysed by thin-layer chromatography (TLC) and high performance liquid chromatography (HPLC). Three major and two or three minor components were detected by both methods and the variation in the quantity of the major components with time was observed. 相似文献

In patrilineal societies, surnames and Y-specific haplotypes and haplogroups are expected to be correlated. This characteristic could help defining an initial pool of suspects in forensic genetics analysis. Here we evaluated this correlation in a sample of Central-Brazilian men. Surnames and Y-SNP haplogroup and Y-STR haplotype were analyzed in 55 pairs of Central-Brazilian men sharing surnames (n = 110). Seven haplogroups and thirty-two haplotypes have been observed, none correlated solely to any of the twenty-eight surnames represented here. In this sample, two men with the same surname showed a chance of 0.41 of sharing a Y-specific haplogroup. This chance is higher for surnames of intermediate frequencies, whereas rare surnames show distinct chances as zero and one. Observed results may be over-estimated due to a predominance of a specific haplogroup (P92R7 = 49%) in the sample, what makes it possible for two men with no coancestry to share this haplogroup. Considering STR, only three pairs of men shared haplotypes. The average difference between the haplotypes in each pair was 2.45 mutational steps. This relatively low correlation is due to some historical and cultural peculiarities of the country, what makes it improper for forensic purposes in Brazil. 相似文献
