The introduction of new technologies is associated with a major change of employment in society, from the traditional agricultural and manufacturing sectors, to the service sector. The availability of more and better services will, according to some analysts, generate wealth that will absorb the surplus labour made available from the traditional sectors. We believe this will be at best a short-term phenomenon. In the longer term, many service sector jobs will be taken over by computer-based systems. In addition, for most people employment also provides security, a pattern for their day, social relationships, a place to belong, and the opportunity to be involved in learning. These will be difficult to achieve in the newer jobs, and much more difficult for the jobless or those in short-term employment. It is critical that the meaning of ‘work’ in society be re-examined.

Under a regime in which ‘hard’, technological systems are programmed to treat society as a collection of individuals, we see the need to develop social, political and economic decision-making tools from the ‘soft’ systems viewpoint. These are not predictable from the sum of individual properties; they are properties of the system, and of the system alone. We also discuss analogies between societies and nonequilibrium thermodynamic systems, which we believe can be helpful when looking at questions involving invention of futures.  相似文献

Oral Cancer is one of the five leading sites of cancer in Indian population. The circulating immune complexes were investigated in 100 serum samples of 60 oral cancer patients having different grades of the disease and 40 patients with precancerous lesions obtained from Nair Hospital Dental collage, Mumbai. The results obtained were compared with those of group of 40 healthy blood donors. Elevated levels of Circulating Immune Complexes were observed in oral cancer patients and patients with oral precancerous lesions. 92% positive samples were observed in well differentiated squamous cell carcinoma whereas 100% positive samples were observed in both moderately and poorly differentiated squamous cell carcinoma. Oral leukoplakia and oral submucous fibrosis showed 15% and 90% positivity respectively. Increased level of Circulating Immune complexes in high grade tumor suggest that Circulating Immune complexes is likely to contribute in evaluating the degree of malignancy, but follow up study is needed to draw any conclusion regarding it's prognostic role  相似文献

Abstract

The U.S. Department of Agriculture has been mandated to “acquire and diffuse among the people of the United States useful information on subjects connected with agriculture in the most general and comprehensive sense of that word. …” With this authority the department has taken advantage of continuing advances of communications and computer technologies by initiating several programs related to the electronic dissemination of agricultural information. For example, the Foreign Agricultural Service has begun testing the release of agricultural trade leads through the University of Nebraska's AGNET computer‐based network. The Agricultural Marketing Service disseminates updated market data on more than 150 farm commodities over its leased wire market news network; the system has 140 terminals linked by some 14,500 miles of leased wires. Additional projects described in the article include a pilot project to deliver market news information to farmers via public television, programs testing the electronic marketing of livestock, and the electronic mail network operated by the department's Office of Governmental and Public Affairs.  相似文献
