The implications of the residential concentration of minority populations are issues of vital concern in the United States. Much of the previous minority concentration literature has focused on African-American residents of metropolitan communities. This article expands on this literature by exploring a variety of minority groups in nonmetropolitan communities. It was found that the minority residents of communities with large minority populations were in worse socioeconomic conditions than the minority residents of predominately white communities. Further, for most socioeconomic variables, it was found that as minority concentration increased, white residents tended to do better. In addition, the extent of racial inequality between minority and white residents was greater in communities with larger minority populations. Implications of the above findings are discussed.  相似文献

Abstract In recent years, the most pronounced change in the structure of American agriculture has been the increasing concentration of farm production. A human ecological perspective was used to generate hypotheses about the factors related to variations in farm concentration in U.S. counties. Analysis using the 1978 and 1987 Censuses of Agriculture revealed that concentration is greatest in counties with higher levels of agricultural intensity, greater use of mechanization, and greater use of farm labor.  相似文献

In this paper, I examine how video methods are used to record what people do as a basis for generating ideas, constructing data, testing hypotheses, and developing grounded theory. Fieldwork with a camera captures emergent social structure and processes that arise from human interaction. While the discovery of serendipitous findings through video methods provokes new theoretical questions, this intrusion into the lives of others also raises ethical and legal issues for the researcher. I conclude that video methods constructively reorient the investigator to the behavior being studied.This research was supported in part by DHEW-SRS grant number 16-P-56809/5-07 NIH and National Library of Medicine grant number 5 K10 LM 0063-02. My thanks go to Doctors Henry Betts and Byron Hamilton from the Rehabilitation Institute of Chicago who offered strong support throughout the three years of this research effort. My appreciation also goes to Meredith Gould for editorial assistance with this paper and to Sean Keenan of the Rehabilitation Institute of Chicago who made the cover photo possible.  相似文献

Abstract Despite literally dozens of attempts, and the expenditure of billions of dollars, efforts to site radioactive waste disposal facilities in this country have been uniformly unsuccessful. While both researchers and policymakers continue to address reasons for these failures, little attention is being given to the consequences for the communities themselves of these intensive siting battles. Using a research framework that addresses both the sources and consequences of community conflict, we examine what is happening in four different areas currently being considered as potential hosts for either a high- or a low-level radioactive waste facility. Some degree of conflict is observed in each community, although it varies from one area to another based on such differences as potential to experience economic benefits, perceptions of class and ethnic equity, and the role of extra-local players in the controversy. We conclude that current policies lead to inequitable distributions of risk that, in turn, create “fairness” questions that are important both in explaining current patterns of conflict and in anticipating long-term consequences for the affected communities.  相似文献

Using prestige and SES measures requires information on the occupation performed. Because gathering and coding this information is time consuming and expensive, appropriate data are often missing. This article presents proxy-scales that may be used in this situation. These scales are derived from original status measures on the basis of commonly available variables. After presenting the derived status scales their validity is examined. It turns out that they capture approximately half of the variance of the original measures. Using a simple status attainment model, the utility of the derived status scales is demonstrated. Finally, we discuss how the scales may be adjusted to other data structures.  相似文献

The Benefits and Costs of Inequality for the Advantaged and Disadvantaged*   总被引:1,自引:0,他引:1  
Objectives. To test theoretical models intended to improve our understanding of the consequences of increased inequality for advantaged and disadvantaged populations. Methods. The 5 percent PUMS (Public Use Microdata Sample) data from the 2000 Census of Population and Housing were analyzed using a variety of ANOVA and regression techniques. Results. It was found that in geographic areas where inequality levels were high, individuals with low levels of education earn lower incomes than equally educated individuals in areas where inequality levels were lower. Similarly, in high‐inequality areas, individuals employed in low‐paying industries, who were not married, and who were minority earned lower incomes than individuals with similar characteristics in low‐inequality areas. The data clearly show that as the level of inequality increases, the benefits of being advantaged and the costs of being disadvantaged both increase. Conclusions. Support was found for both theoretical models tested in this study. As the extent of inequality increases in the United States, it is apparent from this study that the life chances of disadvantaged individuals diminish and are largely determined by the accident of their birth.  相似文献

Customer product returns are key cost drivers that eat into online retailers’ profits. However, management research has neglected to examine ways of reducing return rates without causing a concomitant decrease in sales. Drawing from signalling and dissonance theories, we investigate the relationship between online retailers’ reputation and product return rates. Two experiments designed to produce causal conclusions show that reputation reduces return rates (Studies 1 and 2) and that return motivation is a boundary condition for that relationship (Study 2). A field study based on an online consumer panel demonstrates the robustness of the negative impact of online retailer reputation on product returns in a setting that emphasizes external validity (Study 3), in comparison with Studies 1 and 2, which maximize internal validity. Study 3 also examines managerially important contingencies of the causal relationship by considering three variables: purchase frequency; retailer type; and customer gender. Overall findings indicate that an online retailer's reputation is a powerful means of reducing product return rates. The findings also show that the strength of the relationship between reputation and product returns is influenced by return motivation and the three variables investigated in the field study.  相似文献

Abstract Two of the most significant changes affecting U.S. society during the 20th century were transformations in family structure and the transition from a nonmetropolitan/farm society to a largely metropolitan society. In this study, classic sociological theory, developed to understand differences between metro and nonmetro society, was employed. Despite contentions that the residence variable is no longer viable, we hypothesized that nonmetro interaction patterns would result in nonmetro residents making more traditional and conservative choices relative to family formation. Analysis of data from the 1995 National Survey of Family Growth provided support for these contentions. Nonmetropolitan women were significantly more likely than metropolitan women to be married at the time of conception. Further, when comparing women who were not married at conception, nonmetro women were significantly more likely than metro women to get married prior to the birth of the child, and were significantly more likely to have the pregnancy result in a live birth.  相似文献

Environmental sociology is founded on the assumption that the natural resource base of a society establishes the limits or constraints within which that society must operate. Thus, a change in the resource base on which a society depends will necessitate changes or adaptations within that society. This study attempts to empirically test these assumptions by looking at the effects of groundwater availability in the Great Plains of the United States from 1940 to 1980. Using a model derived from human ecology theory, it was found that irrigation development had major implications on nonmetropolitan counties during the time period studied. Irrigation development resulted in increased agricultural production, variations in the structure of farm enterprises, and in increased retention of both farm and nonfarm populations.  相似文献
