A growing body of evidence suggests that urban neighborhoods of color experience a dearth of institutional resources, including parks and social services. Yet, little is known of how a key process in the creation and maintenance of racially and ethnically segregated neighborhoods—the flight of whites from integrating neighborhoods—influences the availability of nonprofit human services. Drawing insights from the place stratification perspective and the sociological study of residential segregation by race and ethnicity, we develop hypotheses on the relationship between white flight and nonprofit presence, and test them with a dataset that combines census tract data with data on all nonprofit human service organizations in Los Angeles County in 2001 and 2011. Consistent with the place stratification perspective, we find that white flight is negatively associated with the presence of nonprofit human services after controlling for neighborhood structural characteristics. However, the expectation that the negative effect of white flight on organizational numbers is stronger in poor neighborhoods than in nonpoor neighborhoods is not supported. The negative association between white flight and the presence of nonprofits is equally as pronounced in neighborhoods with low and high levels of poverty. 相似文献

The purpose of this article is to elaborate on the history of the relationship between the political ecological and political economic changes occurring in the Mohawk communities in the Saint Lawrence river valley during the Twentieth Century with three Mohawk efforts at land reclamation in Upstate New York and the reestablishment of a Mohawk residential community in the ancestral homelands of the Mohawk river valley. I demonstrate how each of these efforts is conceptualized and should be understood in historical materialist terms as a social response to the changing social, economic, ecological, and political conditions in those communities and the processes involved in the reshaping and remaking of those communities. 相似文献

Despite an abundant literature exploring the relationship between population growth and forest cover change, comparatively little research has examined the forest cover impacts of family planning use—a key determinant of population growth rates in many developing countries. Using data from a panel survey of farms in the Northern Ecuadorian Amazon, this paper explores whether family planning use affects changes in forest cover. After controlling for household life cycle effects, family planning use among female heads of farm households did not have an independent effect on deforestation, reforestation, or net forest loss between 1990 and 2008. Rather, shorter-term drivers of forest change tend to be associated with household life cycles and shifts in production and consumption. However, family planning will continue to improve development and health outcomes for women by reducing unwanted fertility and may offer longer-term environmental benefits. 相似文献

Existing measures in the literature that are specifically concerned with testing and measuring independence between two continuous variables are all based on examining the definition of independence, i.e., FXY(x, y) = FX(x)FY(y). A new measure is constructed uniquely in this paper that uses the absolute value of first difference on adjacent ranks of one variable with respect to the other. This measure captures the degree of functional dependence attributable to the amount of randomness and the complexity of the underlying bivariate dependence structure in a commensurate way that existing coefficients are incapable of. As a test statistic of independence, this measure is shown to have comparable or better power than existing statistics against a wide range of alternative hypotheses that consist of functional and multivalued relational dependence with additive noise. 相似文献

Gonadotrophin receptor hormone analogues (GnRHa) have been used in a range of sex hormone-dependent disorders. In the management of premenstrual syndrome, they can completely abolish symptoms. The success of GnRHa in the treatment of endometriosis and adjuvant therapy in the management of fibroids is proven. This efficacy does not come without a cost and the side-effects of the hypo-estrogenic state have limited their application. The use of add-back therapy to counter these effects has enabled wider application, longer durations of treatment and an increase in compliance. This review article is an update on the evidence supporting gonadotrophin receptor hormone analogues in combination with add-back therapy. 相似文献

Re-conceptualizing habitus as a complex of inculcated moral dispositions that—particularly within the racialized social system
of the United States—are racially-constituted, this article proposes a framework through which racial conflict and structural/cultural
domination within interracial religious organizations, and perhaps other volunteer organizations, may be analyzed. Drawing
upon qualitative data from a study of fundraising experiences within interracial evangelical organizations, I demonstrate,
first, that racial conflicts within these organizations are best framed as disputes over moral standards arising out of divergent,
racially-constituted, moral dispositions, and second, that these conflicts are worked out via the institutionalization and
instilment of white cultural norms, ultimately resulting in the hegemony of white moral standards within the organizations. 相似文献

In acceptance sampling, producer's and consumer's risk are traditionally based on assumed fixed values of p, the proportion of the lot which is defective. A more useful definition of producer's risk would be the probability of rejecting a lot in which the proportion defective falls within some range of acceptable values. Similarly, a more useful definition of consumer's risk would be the probability of accepting a lot in which the proportion defective falls within some range of unacceptable values. In this paper, we construct measures of these more useful definitions of risk by assuming that p follows either a uniform or triangular probability distribution. The proposed measure yields consumer's risk values, β', which are smaller than the traditionally computed values by a factor of up to twenty times. The proposed measure of producer's risk, α', gives values smaller than traditional values by a factor of two to four times. Decision makers who adopt the proposed measures may be able to reduce sample sizes substantially while maintaining given risk levels. 相似文献

Since the foundations of the contemporary anti-violence movement in the 1960s and 1970s, advocates have sought to establish a critical understanding of domestic violence that we can use to direct our efforts for social change. Yet many advocates and advocacy organizations continue to rely on a problematic narrative of sameness that marginalizes and erases diverse victims’ experiences and needs. In this article, I conduct a critical discourse analysis of the National Coalition Against Domestic Violence Web site to identify outcomes of this narrative for the inclusivity of advocacy efforts. I argue that despite the organization’s numerous claims to represent diverse victims’ experiences, Web site content reveals that its purportedly general account of domestic violence normalizes the experiences of a small group of victims—namely, heterosexual, cisgender women. Further, the Web site’s content greatly limits the potential for thinking about and discussing violence across difference. I conclude with recommendations for changes in advocacy practices. 相似文献

Premature termination challenges the successful outcomes of psychological treatments for gambling disorder. To date, research has primarily identified clients who are at particular risk for dropping out of treatment. A smaller but growing body of literature has investigated when dropout occurs. Typically, those studies have not considered improvement in psychological distress within their operationalizations of dropout and therefore may have misrepresented when dropout occurs. The current study examined when dropout occurs using an operationalization based on the criteria of attaining reliable change in a naturalistic sample of clients with gambling disorder, and the classification rates yielded from that operationalization were compared to the rates from a more common operationalization. Participants (n = 334) were clients meeting diagnostic criteria for gambling disorder at an outpatient private practice who completed a measure of psychological distress at baseline and prior to each subsequent treatment session. A survival analysis was conducted to determine temporal patterns of treatment dropout (i.e., clients who discontinued treatment before realizing reliable changes in psychological distress) and completion (i.e., clients who discontinued treatment after realizing reliable changes in distress) at each treatment session. Forty-nine percent of clients were classified as dropouts, and the majority of those clients did so in the first few sessions. The more common operationalization of dropout classified clients as dropouts when they had improved in their distress and clients as completers when they had not improved in their distress. Discussion centers on the implications of dropout occurring at various stages of treatment and future directions. 相似文献

Objective: To examine racial/ethnic differences in weight perception by sex among U.S. college students. Participants: a national sample (N = 70,267) of college students selected from 2- and 4-year postsecondary institutions (N = 62) during the Fall semester from 2011 to 2014. Methods: This is a secondary data analysis using 4 years of American College Health Association-National College Health Assessment IIb data. Sex-stratified multinomial logistic regression was performed to investigate racial/ethnic differences in body weight perception. Results: Compared with non-Hispanic whites, non-Hispanic black men and women were more likely to underestimate their body weight (p < .01). Asian men and women were more likely to overestimate their body weight than non-Hispanic whites (p < .001). Conclusions: Weight-related interventions should take into account racial/ethnic differences in body weight perception. 相似文献
