System of cities dynamics in newly industrializing nations 总被引:1,自引:0,他引:1
Rapid industrialization in such countries as Korea, Malaysia, and Taiwan suggests that the complex functional structures of cities in the periphery may appear early in development. This paper proposes a 4-stage framework for the dynamics of a system of cities in a developing country undergoing industrialization and encompassing both nonindustrial and industrial development. The synthesis is assessed with evidence from the newly industrializing Asian nations of Korea, Malaysia, and Taiwan. The 4 stages of cities' industrial change include 1) increasing primacy with industrial satellites, 2) increasing primacy with industrial satellites and nodal towns on a transport network, 3) rapidly increasing primacy with rapidly growing industrial satellites and nodal towns on the transport network, and 4) decreasing primacy with slowly growing industrial satellites and rapidly growing peripheral industrial towns. The 4-stage synthesis suggests that economic development in the periphery may occur even while the primate city maintains its hegemony over control and coordination functions. Peripheral industrial growth does not challenge this hegemony. The growth of industrial cities is, instead, part of a process of regional specialization in which the low cost labor in the periphery becomes an attraction for industry. These stages are not inevitable. Government efforts are necessary to develop rural areas in terms of social improvements (education and health), capital infrastructure (transportation and utilities), and fair payments to farmers for their outputs. These seem to be the lessons learned from the industrialization process in Korea, Malaysia, and Taiwan. 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 19-year-old school boy suffered from fluctuating uncharacteristic chest pain in the last 20 h before his death. He died unexpectedly within a few minutes of a hemopericardium, which resulted from an aneurysmal rupture of the ascending aorta. The patient's past history as well as the autopsy and ultrastructural findings led to the diagnosis of Marfan's syndrome with alterations of the cardiovascular skeletal system but no ophthalmological involvement ("oligosymptomatic" form of Marfan's syndrome). Appraisal of the cause of death is made more difficult by the fact that medical treatment was undertaken on the same day, whereby subtotal liver crushing was established that had resulted from attempts at resuscitation. 相似文献

The future of public health law 总被引:1,自引:0,他引:1
L O Gostin 《American journal of law & medicine》1986,12(3-4):461-490
Developments in medicine and constitutional law dictate modification of public health legislation in the United States. Traditionally overlooked by legislators, present public health laws provide inadequate decision-making criteria and inappropriate procedures for dealing with issues. Revised legislation should provide health care officials and agencies with the tools to balance individual rights against public health necessities. This Article makes four recommendations for legislative reform: (1) remove artificial legislative distinction between venereal and other communicable diseases; (2) provide criteria defining "public health necessity" to limit discretionary exercise of police power by health officials; (3) provide strong confidentiality protections in the collection and storage of public health information; (4) empower public health officials to select from a graded series of less restrictive alternatives in dealing with public health problems. 相似文献

Legislative and educational alternatives to a judicial remedy for the transfer trauma dilemma 总被引:1,自引:0,他引:1
E S Cohen 《American journal of law & medicine》1986,11(4):405-432
Transfer trauma is alleged to be an increase in morbidity and mortality in institutionally relocated chronically ill elderly. Efforts by the legal profession to persuade courts that transfer trauma should be a legally recognized phenomenon invoking judicial protections against transfer (the "transfer trauma argument") have been unproductive. In O'Bannon v. Town Court Nursing Center, Inc., the United States Supreme Court denied standing to elderly persons claiming a property interest in remaining in alleged substandard facilities. The Court rejected the argument that the possibility of transfer trauma constituted a deprivation of life or liberty that would have required due process protections of notice and hearing. Despite the Court's preclusion of transfer trauma litigation in a constitutional context and the general unwillingness of lower courts to recognize the phenomenon, attorneys continue to burden the judicial system with frivolous transfer trauma arguments. The unfruitful pursuit of a judicial remedy for the ethical and social problems that arise with relocation of the elderly continues, in part, because of a misguided belief that this distressing social phenomenon is best remedied by the courts. Judicial unwillingness to recognize the transfer trauma argument, however, does not preclude legislative consideration of the humanitarian issues concerning the institutional relocation of elderly persons. This Article examines gerontological research in order to understand the judicial rejection of the transfer trauma argument and argues in support of legislative and educational solutions for the ethical and social problems attending transfer. 相似文献

Adolescent incest sexual perpetrators seen at an out-patient clinic were interviewed regarding demographic characteristics and occurrence of deviant and nondeviant sexual behaviors. Results indicate that subjects (1) committed more sexual crimes than they had been arrested for, (2) reported a very early onset of sexual behavior, (3) had additional DSM-III psychiatric disorders, and (4) reported previous sexual victimization. Recommendations for future research are made. 相似文献
