Through the vehicle of the Winnipeg and Edmonton Area Surveys of 1981 this paper compares perceptions of the city by its residents in two cities of dramatically different growth rates, holding constant the region of the country, the size of the city, the time of the analysis and the methodology used. The growth rate did influence the evaluations of the attributes of the city by its residents. However, this evaluation of growth was not a significant contributer to overall satisfaction with the city. While levels of satisfaction with the city were similar in the two cities, the contributing variables differed somewhat. 相似文献

Summary This paper discusses the analysis of selective predation experiments with two types of prey when the prey are not replaced
after they have been removed by the predators. In an earlier paper (Manly
et al., 1972) consideration was given to situations where the replication of experiments allows the estimation of standard errors
from the experimental results; in the present paper a table of standard errors is given for a large range of experiments and
replication is therefore no longer necessary. The standard errors were calculated on an electronic computer by solving the
exact equations given in the earlier paper.
The suggested method of analysis is illustrated using some data where the prey were red and yellow artificial ‘maggots’ and
the predators were garden birds. 相似文献

Objective. I examine where Texas students send their SAT scores in 1998 to identify their revealed preferences for higher education and determine if race/ethnicity influences their decision. Methods. Using data from the Texas Schools Microdata Panel, I estimate the influence of race/ethnicity on various college choice sets using a multinomial logit model. Results. The empirical estimation indicates that minorities perceive their opportunities at Texas public institutions to be different from whites. Furthermore, although blacks and Hispanics are less likely than whites to send their SAT scores to selective Texas institutions, they are more likely to send their scores to selective institutions out of state. Conclusion. Although the reasons for this are currently unclear, a possible suspect is the Hopwood v. Texas decision, a court ruling ending affirmative action initiatives in the admissions decisions of all Texas public colleges and universities. 相似文献

The contraceptive habits of the Arab population in rural Israel was explored by means of a cohort ( n =429) of rural Muslim women, with the aim to compose a profile of the women who practice modern contraception. Self-reported information revealed that only one third of the women apply modern contraceptive devices. Multivariate analysis showed the following independent variables to bear a contributory and predictive value with respect to use or non-use of modern contraceptive means by Muslim village women in Israel: degree of religiosity of the woman, male offspring, extent of modernity within the nuclear family, number of children, occupation of the husband, and adherence to traditional norms by the woman. 相似文献

This paper analyzes health policy development in Europe in response to economic instability, and describes agreements and declarations at a European level as well as commitments in some selected countries. One significant example is the European Health for All Strategy, which encompasses 38 operational targets agreed upon by all 32 member states of the European region. The Council of Europe and the Commission of the European Communities have instituted study groups on psychosocial and health effects of long-term unemployment, and on intervention measures taken or contemplated. This paper discusses interventions such as psychological and socio-pedagogic training schemes, measures for long-term unemployed, and a "social guarantee" of employment or training, as well as prevention of unemployment and empowerment of the unemployed. A local approach in a region of the Federal Republic of Germany illustrates the need for political involvement and strategies. 相似文献

In formulating empirically tractable, economywide models, researchers are often forced to employ “convenient” functional forms. These forms embody restrictive maintained hypotheses. Alternatively, flexible functional forms may be utilized in a partial equilibrium setting. Estimation and incorporation of flexible functions into computable general equilibrium models is considerably more demanding of research resources. Assuming that shortcuts will continue to be necessary for researchers attempting to respond to current policy problems, this paper compares these two alternatives. Specifically, a general equilibrium model for New York State is employed to evaluate the relative performances of flexible partial equilibrium models and their more restrictive, general equilibrium counterpart. In the particular application considered, the former approach is found to dominate the latter. 相似文献

Objective. This study used the differential‐outcomes hypothesis as a theoretical guide to examine the association of Guam's same‐sex‐ and both‐sex‐oriented Asian‐Pacific Islander adolescents and their participation in defensive aggression. Methods. Using ordinary least squares multiple regression analysis we tested the hypothesis with a probability sample of Guam's Asian‐Pacific high school students. Results. The results of the study demonstrated that same‐sex‐oriented males were less likely to participate in physical aggression and that same‐sex‐oriented adolescent females were significantly more likely to report that they had participated in defensive aggression. Conclusions. Same‐sex‐oriented females are more likely than same‐sex‐oriented males to participate in defensive aggression, primarily because they may be more likely to experience threatening situations on Guam's high school campuses. 相似文献
