A contribution to the discussion of probabilities and human hair comparisons

The paper by Gaudette and Keeping on "An Attempt at Determining Probabilities in Human Scalp Hair Comparison" in the Journal of Forensic Sciences (Vol. 19, No. 3, July 1974, pp. 599-606) has provoked considerable controversy. This paper highlights two of the sources of the controversy and shows how the probability, 1/4500, quoted by Gaudette and Keeping should be treated with caution. The necessity of the use of a likelihood ratio statistic is described. It is suggested that the hair examination form resulting from the responses to the questionnaire recently distributed by the authors and also the discussions at Quantico (Proceedings of the International Symposium on Forensic Hair Comparisons, 25-27 June 1985, Quantico VA) should be used to facilitate the collection of the data which will be necessary to enable a likelihood ratio statistic to be estimated effectively.     

The evolution of employment in Mexico: 1895-1980

Employment figures from the Mexican national census are the basis for this analysis of employment changes in Mexico between 1895-1980. The work identifies longterm trends in the volume and composition of employment and distinguishes 3 main periods in the evolution of employment. The first period, from 1895-1930, marked the end of a stage of development lasting until about 1907 in which sufficient internal stability was achieved to support Mexico's entrance into the world market. Export of agricultural products and metals was the principal focus of economic growth. Construction of roads and railroads was a central element of progress. But economic and social problems manifested in regional disparities, concentration of wealth, conflicts between economic sectors, low pay for agricultural workers, and fierce social and political control characterized the period and culminated in the Mexican Revolution. After the first decade of the 20th century the ability of the economy to absorb new workers began to decline, and the falling of crude activity rates was not reversed until the 1940s. During the 1920s, total employment increased less than 6%, reflecting a net increase of 403,000 male workers and a decrease of 110,000 female workers. The second major period of employment from 1930-1970 saw the change from an economy based on export of primary products to one based on manufacturing for the internal market. There were 2 subperiods, a stage of transition from 1930-50, the economy registered marked fluctuations, but by the 1940s the consolidation of state power and important reforms permitting expansion of the internal market were factors in an accelerated growth of employment relative to the preceding intercensal period. Despite considerable increases in agricultural employment, the relative share of the agricultural sector in total employment was beginning a decline. Employment registered the highest growth rates of the century in the 1940s and exceeded population growth. The increased employment was explained by accelerated growth and accumulation in manufacturing along with increases in commerce, services, construction, and agriculture. From 1950-70, industrial development was consolidated, and there was a generalized expansion in employment in manufacturing as well as in the secondary and tertiary sectors. The economy was less able to absorb new labor, primarily because the agricultural sector had reached the limits of expansion in both the commercial and peasant sector by 1965, at just the time that population growth was most rapid. During the 1970s, manufacturing employment grew less rapidly because of modernization, almost exclusive orientation to the internal market which limited expansion, and scarcity of funds for importing capital goods. A new model of growth will be needed if Mexico is to escape its present stagnation, and a significant share of economic activity will need to be oriented to export. Until this process is consolidated, the national economy is unlikely to show signs of sustained recuperation.

Unusual hanging deaths

Four unrelated hanging deaths involving young white males, all in enlisted status in the United States military, are presented. Taken in a military context, one scene served as a suicide note equivalent with the unmistakable message of extreme defiance toward military regulations. In two cases, the elaborate attire of the decedents could have lead to the misclassification of the manner of death if investigative information had not been considered. Extensive background investigation and review of medical records in the fourth case disclosed that the victim had an eight- to ten-year history of compressing his neck to cause unconsciousness. He left an extensive suicide note in which he concluded that "hanging would be good." Each case has certain unique features, as a group, the cases all demonstrate a continuum from obvious suicide to cases where the manner of death is, at first, equivocal.     

The impact of health maintenance organizations and competition on hospitals in Minneapolis/St. Paul

The Healthcare Educational and Research Foundation (HERF) in Minneapolis undertook a two-year research project to study the effects of health maintenance organizations (HMOs) and competition on the hospital industry in Minneapolis/St. Paul. This article summarizes HERF's major findings surrounding three key questions: (1) do the HMOs in Minneapolis/St. Paul use fewer hospital resources relative to conventional payers?; (2) do recent overall community trends in inpatient use suggest evidence of hospital utilization-reducing effects attributable to HMOs?; and (3) given the highly visible competitive process among Minneapolis/St. Paul providers, do hospital cost and revenue data suggest any evidence of cost-containment? The findings (based on data through 1982) indicate that for comparable patients, Twin Cities HMOs appear to use fewer medical care resources per hospitalized patient. There was, however, no clear evidence of community-wide, utilization-reducing effects directly attributable to the "competitive effect" of HMO introduction and development in the market. In addition, there was no empirical evidence that HMOs (which had enrolled 25 percent of the consumer market by 1982), or other large buyers of inpatient services, have selected hospitals on the basis of price as hypothesized by competition advocates.

Legalization of consensual unions in Mexico

Data examined in this study are from the 1976 Mexican Fertility Survey. The authors review previous findings and compare information from this survey with data from the 1969 PECFAL Survey. They then examine the types of consensual union and factors such as women's age, educational status, occupation, premarital fertility, and rural or urban residence. The focus of the study is on the extent to which consensual unions eventually become legal marriages. The authors also investigate the increasing probability of termination of marriage through divorce or separation, especially in urban areas.     

Practitioner fraud and abuse in medical benefit programs: government regulation and professional white-collar crime

Physicians who defraud and abuse medical benefit programs provide a unique group of lawbreakers for scientific study. They could be considered to epitomize white collar criminals given their exceedingly high socioeconomic status and power as a professional group. Using official reports and documents, as well as interviews with enforcement and program personnel at both state and federal levels, this study examines the problem of physician fraud and abuse in Medicare and Medicaid. Major areas relevant to understanding this phenomenon and its control are presented and policy implications of present knowledge in the area are discussed.
