Summary. Long waiting times for non-emergency (elective) procedures are a central feature of the UK's National Health Service, with about 1 million people waiting for surgery at any one time. This paper develops empirical models of the demand for and supply of elective surgery which simultaneously determine waiting times. The models are tested by using a panel of annual data for 5499 small areas from 1991 to 1998. Supply and demand functions are estimated for all specialties combined and for seven individual specialties, using panel data methods that incorporate simultaneously determined variables. The elasticity of demand with respect to waiting time varies between specialties but is always quite small. The results are discussed in the light of UK Government policy initiatives designed to reduce waiting times substantially. The analysis suggests that these initiatives will not stimulate demand markedly and therefore stand a good chance of succeeding provided that adequate additional resources are made available. 相似文献

The state of American Sociology 总被引:4,自引:0,他引:4
Seymour Martin Lipset 《Sociological Forum》1994,9(2):199-220
Sociology appears to be one of the most internally divided disciplines, if not the most. Departmental struggles, which have led to sociologists complaining to administrators about each other, have put the field in bad repute among campus officials and have endangered its survival in some schools. The American Sociological Society and American Sociological Association have been among the most conflict-ridden associations in academe for generations. Severe internecine struggles have a long history in the field. It may be suggested that they are related to the propensity of the field to attract social reformers and political activists. But hard evidence indicates sociology graduate students are among the weakest, as judged by test scores.This is an elaboration of an American Sociological Association presidential presentation to a plenary session of the Southern Sociological Association on April 2, 1993. 相似文献

In this article, the authors examine the characteristics of leisure that are of relevance in planning and look at some of the key leisure issues for the 1980s. The most fundamental question is how people will choose between extra income and more free time? This influences the rate of economic growth as well as the pattern of leisure activities. The authors see leisure as representing a cost, as well as an opportunity, for the U.K. in the 1980s.1 相似文献

The imperfect empiricism of the social sciences 总被引:1,自引:0,他引:1
Martin E. Spencer 《Sociological Forum》1987,2(2):331-372
The social sciences suffer from a methodological false consciousness that calls into question their progressive nature as cumulative, knowledge-building enterprises. While the practioners of social science believe that they accumulate knowledge through a classical scientific dialectic of hypothesis and evidence (scientific empiricism), they in fact assume their hypotheses to be true images of the nature of the social world, and they resist evidence that gainsays these images (imperfect empiricism). The idea that the social sciences progress, in a linear or dialectical fashion, is itself derived from the perspective of scientific empiricism. In reality the progress of the social sciences is problematic, if the movement of these sciences is viewed in terms of their actual practice of imperfect empiricism. Seen from the latter perspective, the social sciences are—at any particular moment in time—an aggregate of conceptual communities that communicate only imperfectly with each other and that assert the correctness of their point of view while disdaining that of the others. Since the progressive advance of knowledge is uncertain in these circumstances, the question is raised as to why the natural sciences that—according to Kuhn—are also practioners of imperfect empiricism work, while the social sciences apparently do not. 相似文献

Martin PL 《The International migration review》1985,19(1):135-143
The May 1984 Conference on Migrant Labor in Agriculture at the University of California-Davis discussed papers by 22 farm labor experts from 12 nations. Each industrial nation utilizes a different set of public and private policies to supply workers for labor-intensive agriculture, but none is entirely satisfactory. Labor-intensive agriculture is becoming more dependent on workers who are shut out of labor markets. Some countries have simply accepted foreign workers in agriculture, while others have adopted policies to integrate farm and nonfarm labor markets. Polices to reduce agriculture's reliance on workers-without-options include restructuring employment practices to employ fewer seasonal workers for longer periods, mechanizing production, and importing fruits and vegetables from nearby developing countries. This article explains the salient features of labor-intensive agriculture, the various polices for obtaining seasonal farmworkers, and options to reduce farming's dependence on migrant labor. 相似文献

Incompleteness in the reporting of illegitimate births in the U.S. vital registration system due to the consistent nonparticipation of a number of large States has left data published by the National Center for Health Statistics open to considerable criticism. Utilizing retrospective marriage and fertility data from the June 1978 Current Population Survey, a national probability sample of 54,000 interviewed households, a time series on teenage illegitimacy for first births is constructed that permits an evaluation of similar Vital Statistics data on teenage illegitimacy since the 1940s. Although there are some indications of a slight underreporting of white illegitimate first births by Vital Statistics during the 1940s and early 1950s, the overall comparison produces a general consensus between the two data sources on the incidence of illegitimacy among both white and nonwhite teenagers for the period 1940–44 to 1970–74. 相似文献
