There has been a perceived increase in the number of medical negligence claims in recent years. The modern metropolitan medical examiner is increasingly called upon to deal with numerous medical, legal, social, and ethical issues. Nowhere is the role of the medical examiner more important than in the investigation of deaths related to surgical, diagnostic, anesthetic, or therapeutic procedures. Medical examiners have an important role in the investigative process. Through utilization of the offices and services of the medical examiner, questions raised by families, physicians, and other hospital employees may be satisfactorily answered a priori, and litigation may therefore be averted.  相似文献

"This article presents some of the latest available figures on illegal immigration in Japan, a process that did not assume significant proportions until the mid-1980s. It also discusses briefly the latest developments around 'immigration' policy--more precisely, the law on the entry and exit of aliens."  相似文献

Merowe province in rural northern Sudan has been divided into three local government council areas: Merowe, Karima, and Ed Debba. A government program was instituted to increase the welfare of residents and food production. A baseline survey of 490 respondents was conducted in order to ascertain how illiterate women viewed development in the area and to provide useful information for program design and implementation. Women from 24 villages were administered questionnaires, observed in their daily activities, and engaged in discussion in a local meeting place. Discussions were also held with members of the local Popular Committee. Demographic information was very sketchy about age, and 48% had no formal education in writing and reading. General reading and writing skills of the remainder were very poor. There were 500 female children and 502 male children, and the sex ratio varied among the 3 council areas. 52% were married and 14% were divorced or widowed and living with relatives. The average monthly income was from Ls. 700 to Ls. 3000 based on reports from only 59.3% of respondents. Most of the women had skills in food processing and 25.7% were skilled in handicrafts. Water was obtained primarily from local wells and not decontaminated before use. Pit latrines were the standard. One bathing facility was available in the compound for the entire council area. Health units were either in each village or within 20-30 minutes walk. Child mortality was 4.3% in Merowe province. 77 children 0-5 years old died out of a total of 1002 live births. Life expectancy was 41-50 years for women and 61-70 years for men. Cleanliness and healthful eating were observed. 58% owned no land; plots were under 5 feddans and usually half a feddan. 92.1% had no bank account and 90% had no experience with loans. 70.2% were indifferent about involvement in an income generation program. 26% were interested in part-time participation. Only 3.9% desired full-time participation. 8.6% said they wanted raw materials to produce handicrafts, and 21% said they wanted cash to raise livestock. 28.4% had radios. 80.4% lacked any farm equipment. 7.6% owned an electric pump and 7% had an ox plough. A program could be offered after lunch and coordinated with other activities after 4 P.M. at a local center. The population would have to be oriented to business and income generation would have to be planned very carefully.  相似文献

"Teacher, what are we going to do next class?" This is an exciting question which I often hear from my students. As an English conversation teacher, I can make the learning of English either a dull and boring duty, or an exciting adventure. It is very important that I make my students hate missing my class, and keep them guessing just what will happen the next time! Let us consider some important ways that any teacher can help his other students want to do their  相似文献

"This article examines the probable effects of the North American Free Trade Agreement (NAFTA) on migration from Mexico to the United States, disputing the view that expansion of jobs in Mexico could rapidly reduce undocumented migration. To the extent that NAFTA causes Mexican export agriculture to expand, migration to the United States will increase rather than decrease in the short run. Data collected in both California and the Mexican State of Baja California show that indigenous migrants from southern Mexico typically first undertake internal migration, which lowers the costs and risks of U.S. migration. Two features of employment in export agriculture were found to be specially significant in lowering the costs of U.S. migration: first, working in export agriculture exposes migrants to more diverse social networks and information about U.S. migration; second, agro-export employment in northern Mexico provides stable employment, albeit low-wage employment, for some members of the family close to the border (especially women and children) while allowing other members of the family to assume the risks of U.S. migration."  相似文献

Beyond the theoretical basis for integration, three core considerations stand out as the primary reasons for pursuing integration from a physician's perspective. In the authors' experience, the ability to make a case for physician integration stands or falls based on the ability of the integrated delivery system to address these considerations: Gain greater access to capital; develop human resources with talents in managed care and the full spectrum of care services; and sustain an information infrastructure. This article explores the lessons learned in pursuing physician integration.  相似文献

"While several studies (in both Turkish and English) have been made on migration to the Ottoman Empire from the Caucasus and the Balkans during the nineteenth century...very little systematic and comprehensive research on migration has been undertaken on the period since the establishment of the Turkish Republic. This article, which aims to partially fill the gap, is divided into three parts: the issue of national refugees (refugees of Turkish origin) in relation to Turkey's overall refugee policy; Turkey's policy towards national refugees; and the volume and causes of refugee migration to Turkey since 1945."
