Alison M. Gill 《Social indicators research》1991,24(2):177-204
New resource towns on the Canadian frontier have presented planners with opportunities to experiment with innovative planning ideas which attempt to resolve the persistent problems of such communities. In the planning of Tumbler Ridge, a new coal mining town in British Columbia, socially responsive planning was an attempt to develop a town using principles derived from social science research. In this paper the reactions of residents to selected attributes which reflect the application of these principles are examined five years after settlement began. Ratings of community attributes offer an indication of aspects of residential satisfaction, while the results of a principal components analysis suggest the dimensionality of residents' evaluative structures and provide a useful framework within which to consider planning issues. Issues examined are: the association between employment and the community environment; the suitability of the environment for children; and the social environment. While social aspects of the new community are judged as satisfactory, less positive elements reflect the underlying influence of the economic well-being of the mining company on overall community satisfaction. When compared to indicators of community satisfaction in other western Canadian resource towns, ratings for Tumbler Ridge tend to be fairly low. It is concluded that the inability of planners to adequately control implementation or dontinuity of their ideas has resulted in a community not distinctly different from other resource towns. Efforts have been further hampered by a lack of adequate models of the distinctive dynamics of resource communities. 相似文献

This paper extends earlier research into methods for estimating adult mortality from information on the recent incidence of orphanhood. It presents a series of regression coefficients for estimating female and male mortality from synthetic cohort data on the subsequent orphanhood of those who had a living mother or father at exact age 20. Such information can be obtained either where questions about parental survival have been asked in two inquiries or by asking retrospectively about dates of orphanhood in a single survey. Although the method is somewhat sensitive to errors in the reporting of ages and dates, it is a promising source of up-to-date estimates of adult mortality that are free from bias due to the underreporting of the orphanhood of young children ("the adoption effect"). 相似文献

74 labor migrant families from various socioeconomic classes in Amman, Jordan were interviewed to examine changes in relationships among family members, extended family, and neighbors and their concerns about economic stability in the host country, Jordan, and the world market. Another purpose was to determine how current migration policies of the Arab oil-producing countries which prohibit labor migrants from bringing their families to the host country affect labor migration among families. The families consisted of either those who did or did not accompany the labor migrant. Overall labor migration affected unaccompanied families more than accompanied families, e.g., only 19% of the unaccompanied families reported increased family unity compared with 56% of accompanied families. Problems within unaccompanied families increased in 43% of the cases but in only 6% of the accompanied families. Many of these problems resulted in children dropping out of school which reflected the control fathers had within the family, separation, or divorce. Yet labor migration reduced family ties with extended family members and neighbors almost equally for both groups. Accompanied families were not as concerned about economic stability in Jordan as unaccompanied families (38% vs. 50%). Perhaps these families tended not to invest remittances received from the labor migrants working in Arab oil-producing countries in Jordan. Both groups were quite concerned about the economic stability in the host countries (66% and 72%, respectively) and the world market (59% and 62%, respectively), however. Since family unity suffers when families do not accompany labor migrants, it is suggested that oil-producing nations that depend on foreign labor should guarantee family unity as a human right. 相似文献

The effects of regulatory tools on organizational populations 总被引:6,自引:0,他引:6
One of the main activities of regulation is the control of market development by influencing the number of firms in an industry, their entry into an industry, and their exit from an industry. Population ecology is used as a framework for explaining both the direct and indirect effects of regulatory activity on entry, exit, and market structure. This framework is then used to derive specific propositions about regulatory effects on entry, exit, and market structure in the health maintenance organization industry. 相似文献

Common sense has to do with problem solving. In the complexities of everyday human life, we are faced time and again with the need to solve problems. In fact, every situation we face, at least at the first exposure, requires some form of problem solving. When we want food, we have to solve a series of problems from acquisition to preparation to serving and eating. When we deal with organizational needs, problem solving is the daily fare. 相似文献

Information about board-and-care homes reported in the media and in federal committee hearings indicates that they are shoddy and exploitative environments that do not provide adequate care. Research done in board-and-care homes in recent years, however, demonstrates that they can provide adequate care and a satisfying environment for some of the people they serve. Policy at the federal, state, and local levels should be guided by both the need to assure the health and safety of board-and-care residents and the needs of residents and operators identified in scientific studies. 相似文献

RACE-OF-INTERVIEWER EFFECTS IN A PREELECTION POLL VIRGINIA 1989 总被引:1,自引:0,他引:1
All published preelection surveys of the 1989 Virginia gubernatorialcontest overestimated the vote share of the black candidateand eventual victor, Douglas Wilder. We offer a "social desirability"interpretation of the polls' inaccuracies and hypothesize thatclaiming support for Wilder was the socially desirable responsefor some whites, especially when the interviewer was black.We show a race-of-interviewer effect on the vote intention ofwhite respondents of 8–11 percentage points in a preelectionsurvey of Virginia voters. The effects were greatest among whiteDemocrats and among whites who were more uncertain of theirvote intention. We discuss the implications of these findingsfor race-of-interviewer research and for improving the accuracyof preelection forecasts in contests with black and white opposingcandidates. 相似文献
