In this paper, we examine whether investments in higher education have contributed to changes in occupational inequality by
focusing on the impact of college completion rates on movement into desirable occupations between 1983 and 2002. Since forces
generating inequality vary by gender, race, and ethnicity, we examine trends for white, black, and Hispanic men and women
in our study. Utilizing Ordinary Least Squares Regression on data from 20 Current Population Surveys, we find a modest decrease
in both gender and racial inequality in access to desirable occupations and an increase in inequality between Hispanics and
members of the other groups. College completion accounts for the progress made by white women and for the declines among Hispanic
men. It does not explain changes for African Americans, either between men and women or when compared to whites. 相似文献

Estimates of air pollution mitigation with green plants and green roofs using the UFORE model 总被引:4,自引:0,他引:4
The purpose of this study was to investigate the effect of green roofs and green walls on air pollution in urban Toronto.
The research looked at the synergistic effects on air pollution mitigation of different combinations of vegetation by manipulating
quantities of trees, shrubs, green roofs and green walls in the study area. The effects of these manipulations were simulated
with the Urban Forest Effects (UFORE) model developed by the USDA Forest Service Northeastern Regional Station. While UFORE
contains several modules, Module—D quantifies the levels of air pollution for contaminants such as NO2, S02, CO, PM10 and ozone as well as hourly pollution removal rates and the economic value of pollutant removal. Six vegetation scenarios
were developed within the Toronto study area to compare different subsets of vegetation and their effect on air contaminants.
Results of the study indicate that grass on roofs (extensive green roofs) could augment the effect of trees and shrubs in
air pollution mitigation, placing shrubs on a roof (intensive green roofs) would have a more significant impact. By extension,
a 10–20% increase in the surface area for green roofs on downtown buildings would contribute significantly to the social,
financial and environmental health of all citizens.

Objective. In this study, we examine how contextual factors influence voting behavior on nativist ballot initiatives using California's Propositions 187 and 227. We argue that spatial proximity to the border is associated with voting behavior on nativist initiatives. Methods. To examine the influence of environmental factors on Anglo voting behavior on nativist ballot initiatives, we utilize California Field Polls, U.S. Census data, and spatially referenced data generated using GIS software. Results. The results indicate that spatial proximity to the border is an important component in individual‐level voting on nativist initiatives and that the impact of proximity to the border on the vote for Propositions 187 and 227 varies as a function of individual‐level partisan affiliation. Conclusions. These findings hold implications for future research regarding the influence of geospatial boundaries and political behavior. 相似文献

This article reports on a research partnership between a community-based hospice and a graduate school of social work. The purpose of the collaboration was to design and test a tool for assessing caregiver strain and resources in families caring for older adults receiving hospice home care services. Eighteen hospice home care social workers interviewed 162 caregivers for the study and provided their own assessment of the tool's clinical utility. Both strengths and challenges of the collaboration are evaluated and implications are discussed for social work practice and research, particularly academic-community research partnerships. 相似文献

As a reaction against neo‐liberalism, Social Entrepreneurship has been promoted as the solution to welfare problems brought about by social change and persistent unemployment. The Social Entrepreneurship Movement (SEM) proposes the reconstruction of welfare by building social partnerships between the public, social and business sectors. Major aspects of this agenda include non‐profit organisations undertaking entrepreneurial ventures and the pooling of government welfare funding under the control of local communities. In this paper we argue that the SEM literature is based on two false premises: the failure to understand the true causes of mass unemployment, and the assumption that the government faces financial constraints in the provision of welfare services. We also argue that implementation of the SEM proposals would erode the rights‐based eligibility to universal welfare services based on the principle of social justice. We also conclude that the SEM is indistinguishable from neo‐liberalism and as such does not represent a viable solution to unemployment and the welfare needs that accompany it. 相似文献

The COVID-19 pandemic created multiple stressors for college students, particularly for young adults experiencing multiple forms of disadvantage. Little is known about the pandemic experiences of independent college students, many of whom are emancipated minors, former wards of the state, and other students who lack familial financial and practical support as they pursue higher education. Twenty-three independent students, ages 18–23, from one northeastern university were interviewed to understand how independent students were affected by the COVID-19 pandemic, and their needs for support from the university during this time. Most participants were identified as Black or Latinx, and two thirds were first-generation college students. Participants reported an overall lack of support from their families prior to the pandemic. During the pandemic, they experienced compounding academic, economic, and mental health-related stressors. Students responded to these stressors in resilient and resourceful ways, by adapting to their new realities, expressing gratitude, and finding opportunities for self-growth. Participants recommend that institutions of higher education support independent students during periods of emergency through providing financial assistance, offering opportunities for connection with both adults and peers, and demonstrating administrative flexibility and understanding of their unique needs. 相似文献

Infants by 6 months recognize that speech communicates information between third parties. We investigated whether 6-month-olds always expect speech to communicate or whether they also consider social features of communication, like how interlocutors engage with one another. A small sample of infants watched an actor (the Speaker) choose one of two objects to play with (the target). When the Speaker could no longer reach her target object, she turned to a new actor (the Listener) and said a nonsense word. During speech, the actors were either face-to-face, the Speaker was facing away from the Listener, or the reverse. When the actors had been face-to-face, infants looked longer when the Listener selected the non-target object compared to the target. Infants looked equally regardless of what the Listener chose when either actor had been disengaged. Area-of-interest gaze coding suggests that infants were similarly interested in the interaction across conditions, but their pattern of attention to Speaker and Listener differed when the Listener was disengaged during speech. Although these experiments should be replicated with a larger sample, the findings provide initial evidence that 6-month-olds do not expect speech alone to communicate, but also attend to the social context in which speech is produced. 相似文献

Traditional methods do not capture the multidimensional domains and dynamic nature of infant behavioral patterns. We aim to compare full-day, in-home leg movement data between infants with typical development (TD) and infants at risk of developmental disabilities (AR) using barcoding and nonlinear analysis. Eleven infants with TD (2–10 months) and nine infants AR (adjusted age: 2–14 months) wore a sensor on each ankle for 7 days. We calculated the standard deviation for linear variability and sample entropy (SampEn) of leg acceleration and angular velocity for nonlinear variability. Movements were also categorized into 16 barcoding states, and we calculated the SampEn and proportions of the barcoding. All variables were compared between the two groups using independent-samples t-test or Mann-Whitney U test. The AR group had larger linear variability compared to the TD group. SampEn was lower in the AR group compared to TD group for both acceleration and angular velocity. Two barcoding states’ proportions were significantly different between the two groups. The results showed that nonlinear analysis and barcoding could be used to identify the difference of dynamic multidimensional movement patterns between infants AR and infants with TD. This information may help early diagnosis of developmental disabilities in the future. 相似文献
