Life histories of single parents and illegitimate infants in nineteenth-century Sweden.

"This essay presents tentative findings for the Sundsvall area of Sweden, which is being studied in a recent project on the decline of infant and childhood mortality in the Nordic countries. The focus is on the complete reproductive histories of single mothers and the life expectancies among infants born to women who at least once in their reproductive life history experienced the birth of an illegitimate child. In Sundsvall, industrialization only temporarily affected the illegitimacy ratio, but its effect was obvious even in agrarian parishes. The number of illegitimate children per woman remained relatively stable over time, with the exception of the town of Sundsvall. It was more common in the urban environment to give birth to several illegitimate children. Mortality was also higher among these infants, but the negative effects can be seen equally among both legitimate and illegitimate children."     

Coming soon to the "genetic supermarket" near you

Recent medical studies have indicated that synthesized human growth hormone (hGH) may cosmetically enhance short, but otherwise perfectly healthy, individuals by adding inches to their final predicted height. In this note, Curtis Kin examines the legal and ethical implications of such a discovery, arguing that nontherapeutic hGH treatment is likely the first of many biotechnology and gene therapy enhancements that may be available to the public in a "genetic supermarket" of enhancement products. Mr. Kin finds that the current regulatory framework for biotechnology and gene therapy inadequately regulates unapproved uses of hGH and fails to address properly its implications for a genetic "race to perfection." He proposes changes to the current regulatory framework that will enforce a strict distinction between therapeutic and enhancement applications of biotechnology and gene therapy. These changes in the law, Mr. Kin reasons, will help to solve the social and ethical problems posed by these emerging developments in technology.     

An in vitro study of the accuracy and precision of Breathalyzer models 900, 900A, and 1000

Ninety Breathalyzer instruments (Model 1000) and twenty instruments (Models 900, 900A) were studied using a protocol described by the Department of Transportation's "Standard for Devices to Measure Breath Alcohol." Although the mean of each of three concentrations tested (0.05, 0.10, and 0.15 g/210 L) compared favorably in both series, the standard deviation was consistently higher for the Model 1000 instruments. The Model 1000 instruments also produced a significant number of test results which exceeded the normally expected scientific deviation.
