The computer-mediated network is a moderately expanding phenomenon. A major reason for this growth is the need for transferring technology to developing nations. But because many of these nations are not traditional users of advanced technology and because even the purveyors are not yet fully comfortable with the networks, the medium is not being used as much as perhaps it ought to be. In establishing a multinational network, one should be careful to treat all potential users with equity and not create an informational elite. Part of the challenge of such a system is making it accessible to operatives in the field. An effective way of introducing a network is to blend it with existing technologies, keep the costs down and the quality of information up, provide a usable information-retrieval system, and pay attention to microand macro-ergonomics. The Adult Education Network (AEDNET) of the Kellogg Project at Syracuse University has started working on a next-generation computer-mediated network system. It is proposed that AEDNET involve three action groups in the project: researchers, those interested in social implications, and users.  相似文献

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.  相似文献

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.  相似文献

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.  相似文献

A conference was held at the State University of New York at Stony Brook in October 1984 to discuss the controversy concerning treatment of a newborn with severe congenital defects that became known as the Baby Jane Doe case. Fox provides some background information on the case to introduce a set of of six articles consisting of papers delivered at the conference. These articles deal with historical aspects of the treatment debate (Stanley J. Reiser), problems of clinical decision making (John M. Freeman), the legal issues involved (John A. Robertson), coverage of the case by the media (Stephen Klaidman and Tom L. Beauchamp), federal efforts to regulate the treatment of handicapped newborns (Lawrence D. Brown), and the alliance that arose between opponents of abortion and advocates of the rights of the handicapped (Constance Paige and Elisa B. Karnofsky).  相似文献
