Monitoring the metropolitanization process 总被引:1,自引:0,他引:1
Alternative approaches have led to different interpretations of the metropolitanization process in the United States. We identify and illustrate several methods and procedures for monitoring metropolitan-nonmetropolitan population change using the 1950-1980 U.S. decennial censuses. Two basic approaches are compared: constant area approaches and component methods. In addition, we assess the effects of changing metropolitan definitions on metropolitan-nonmetropolitan growth. The results clearly reveal that the underlying mechanics of metropolitanization not only are complex but have changed substantially during the 1950-1980 period. We conclude with observations regarding the use of these procedures in future research. 相似文献

Participatory research: Three models and an analysis 总被引:2,自引:0,他引:2
This article examines three models of participatory research: what we call the parallel process model, the mutual engagement
model, and the University of Central America (UCA) model. These models represent successively greater degrees of academic
engagement with outside communities—from complementary, though not necessarily uncommitted, engagement by academic(s); to
compromised full engagement between the academic(s) and the community; to institutional engagement between the entire university
and the community.
Our analysis outlines the tensions that may arise within participatory research between service and scholarship. We conclude
that for participatory research to capture the attention and involvement of the broader discipline, it must provide a spectrum
of theory, methods, and substance that sociologists find of importance independent of the participatory way in which such
contributions are generated.
This article is based on a paper presented at the 87th Annual Meeting of the American Sociological Association, D.L. Lawrence
Convention Center, Pittsburgh, Pennsylvania, August 20–24, 1992. 相似文献

This report illustrates how countertransference issues emerged for a consultant therapist whose guidance about practice was sought by an ill and dying colleague. The detechment necessary for consultation was difficult to maintain. Denial, avoidance, and isolation operated for both. Ambivalence about directive behavior developed. Unexpressed grief, shock, feelings of inadequacy, and identification with the colleague intruted but were managed. The occurrence of such countertransference phenomena can be anticipated and understood in a consultation process that represents one valuable, underutilized, and important means of encouraging quality clinical practice under extremely painful circumstances. 相似文献

The aim of this study was to investigate the power of the Average Leadership Style (ALS) and Vertical Dyad Linkage (VDL) models of leadership in explaining relationships between leader's initiating structure behaviour and consideration behaviour, and subordinates' attitudes and perceptions. The considered dependent variables were five facets of job satisfaction, two role stress variables (role conflict and ambiguity), one role strain indicator (job tension), and four dimensions of workteam climate. The relationships were investigated in two occupational samples comprising 127 family physicians and 155 nurses working in 28 Primary Health Care Teams. Within and between analysis (WABA) and contextual analysis were applied in order to determine the appropriate level of analysis (group as expected from ALS or individual as expected from VDL) for studying the relationships between leader consideration and initiating structure behaviours and the dependent variables. The results obtained showed the prevalence of the VDL model in most of the cases, although two of the relationships studied fitted the ALS model. 相似文献

Learning about radon's risk 总被引:1,自引:1,他引:0
V. Kerry Smith William H. Desvousges Ann Fisher F. Reed Johnson 《Journal of Risk and Uncertainty》1988,1(2):233-258
This article reports the results of an evaluation of the effectiveness of different types of information materials in communicating the risk from exposure to radon, a naturally occurring indoor air pollutant. The study involved a panel of 2300 homeowners who actually experienced risks from radon, and the information program used to explain these risks. The analysis considered information transfer and performance on specific tasks requiring information on the risk from radon to measure learning. The results suggest a systematic learning process, but indicate that the process can be influenced by how risk information is presented. 相似文献
