Independent instances of "souvenir" Asian skulls from the Tampa Bay area

In the summer of 1984, police in Pinellas County, Florida, confiscated six identically colored imported Asian skulls (in a shipping case) from a private citizen. In May 1988, in nearby Hillsborough County, police confiscated a very similar skull from another private citizen, who allegedly had found it in an abandoned house. Aside from slight color differences between the six found in Pinellas County and the one found in Hillsborough County, the skulls are virtually identical in their osteological characteristics and condition and in the vital statistics derived from each. Each skull is as clean and dry as those typically sold by commercial scientific supply outlets in the United States. Each is edentulous (primarily premortem), between approximately 20 and 60 years of age at death, and morphologically Asian. Five of the seven are morphologically male, one is morphologically female, and one is a mosaic with respect to gender-related features. Police, medical examiners, coroners, and forensic anthropologists should be aware of such "souvenir" specimens, in the event that they encounter similar skulls. Discriminant function analyses for race and sex yield considerably conflicting results, which underscores the need for using extreme caution when interpreting forensic science estimates based on such techniques.     

The gas chromatographic determination of carbophos in cadaveric material

The authors developed a method of malathion insecticide determination in the cadaveric material (blood and wall of the stomach) including extraction of 5 ml of blood (5 g of fragmented tissue of stomach wall) by hexan; preparative chromatographic purification of extract on silicagel layer L 5/40 mkm in hexan-diethyl ether system 10:2; Gas-liquid chromatographic investigation on column with 5% SE-30 and 5% XE-60 (Chromatograph "Colour-106" with thermionic detector). This method makes it possible to detect 72-76% of malathion added.     

Technology-transfer strategies of DOE's conservation programs

This paper examines the process by which R&D results funded by the Office of Conservation and Renewable Energy (CE) of the US Department of Energy (DOE) have generated commercial applications. It looks at examples of technology-transfer procedures and activitees across three of CE's component offices that correspond to the major energy end-use sectors: transportation, buildings, and industry. On the surface, the conservation programs would appear to have little strategic consistency and, therefore, lack the clear leadership many seek in a technology-transfer program. However, as an alternative to strategic consistency, one may tailor the technology-transfer approach of each program to its unique circumstances. This paper presents case studies of such tailoring, in which the diversity of approaches mirrors the complexity of the energy end-use markets and the private-public interests that must be negotiated to successfully commercialize energy-saving innovations. The paper discusses the lessons learned about the conditions requiring adaptive design and the structures and practices that have been proven effective.     

Work,fertility, and the status of women in Mexico

Among the major transformations affecting Mexican women in recent decades were their growing participation in the labor market and the fertility decline that began in the 1970s with widespread access to contraception. Data from 3 major Mexican fertility surveys, employment surveys, and censuses are used to analyze changes in female employment and their determinants during the years of economic recession in the 1980s. The main characteristics of the Mexican fertility decline are described, and the relationship between fertility and female employment before and during the economic recession is scrutinized for different social sectors. Suggestions for research on the affects of these changes on the social condition of Mexican women are then presented. The proportions of Mexican women over 12 years old who declared themselves economically active increased from 16% in 1970 to 21% in 1979 and 32% in 1987. Until the 1970s the majority of employed women were young and single or childless. But a clear increase occurred between 1976-87 in the economic participation of older women in union. Economic participation of low income and less educated women increased as they sought work or created their own in response to deteriorating living conditions during the recession. Young women with intermediate or higher educational levels did not increase their relative presence in the labor market in the same period. The marked increase in economic participation of less educated women in union with small children was accompanied by a significant increase in manual occupations. Between 1982-87, the proportion of women aged 20-49 in nonsalaried manual occupations rose from 7.6% to 18.5%. Mexico's fertility decline has been well documented. The total fertility rate declined from 6.3 in 1973 to 3.8 in 1986, while the percentage of women in union using a contraceptive method increased from 30.2 in 1976 to 52.7 in 1987. Fertility differentials have been declining but are still considerable. The inhibitory influence of children on female labor force participation in Mexico is clear, but in the years of economic recession the most notable increase in female workers was in women with 3 or more children of whom the youngest was under 3. It appears that the influence of children on women's employment depends on the socioeconomic status of the woman as well as on the dynamism or sluggishness of the labor market. Research is needed on the significance of changes in fertility and female employment for women's status in Mexico. Several recent works have presented results of microsocial analyses of the ways in which women experience changes in their lives resulting from fertility and employment decisions. A methodological strategy for studying these changes and their influence on women's status should focus on comparisons between different generations and birth cohorts, different types of employment, and different socioeconomic statuses. Both macrosocial and microsocial forms of analysis are needed to provide a full picture.
