This issue of the Journal of Social Issues focuses on the psychology, sociology, and public policy of global environmental issues. The goals of the issue are (1) to describe the current state of the environment and environmentalism, (2) to present new theories and research on environmentalattitudes and behaviors, and (3) to explore obstacles and ethical considerations in promoting proenvironmental action. The following brief introduction places this issue within a context of preceding JSI issues, provides a framework for the articles, and highlights several recurring themes that occur throughout the issue. 相似文献

Understanding the effects and consequences of missing data imputation is vital to the ability to obtain meaningful and reliable
statistics and coefficients in the examination of any quantitatively-based phenomena. Over time a series of sophisticated
methods have been developed to handle the issue of missing data imputation however, these sophisticated methods may not always
be appropriate or attainable. In these specific cases more traditional approaches to missing data imputation must be employed
and driven by the research project, theoretical framework, and the data. In this research note we offer a brief account of
one such instance, implementing a large-group mean imputation approach to handling missing data. The analysis is drawn from
a much larger project and shows the effect of proper group selection in terms of mean imputation using a cross-validation
approach based on the imputed data’s relation to known values. Ultimately, the results show that the use of Rural-Urban Continuum
codes are superior to currently used group-means in the U.S., thus introducing a new, and more efficient, approach to the
handling of missing data using group-mean imputation. 相似文献

Securing major gifts for nonprofit organizations can involve considerable cost. This study examines the relationship developed between 233 major gift donors and the development office at Northwestern University over a five-year period. The results show that the cultivation and solicitation process is usually long, measured in years rather than months, and the extent of the effort varies by type of donor and category of gift. Vignettes describing one of the relationships from each of the five most important categories are presented. 相似文献

This article provides the analytical characterization of the inverse of the information matrix for second-order SPD. A particular feature of these explicit expressions is that they are functions of the design parameters enabling the development of analytical functions to efficiently compute exact design optimality criteria. The application of these analytical expressions is demonstrated using the generalized variance of the parameter estimates for second-order SPD. An example illustrating the use of these expressions is also presented. 相似文献

Research on crime over the life‐course has made considerable progress in the last several decades. Despite this growth, significantly less attention has been devoted to longitudinal examinations of Hispanic populations beyond one phase of the life‐course, and/or examining differences between native‐born and foreign‐born Hispanics. Recognizing these limitations, this study offers an investigation of Hispanics in the United States focusing on offending and its relationship to immigration status. Using arrest data from a cohort of 375 Hispanic males from ages 18 to 50, trajectory analysis revealed four unique offending trajectories: very low‐rate offenders, high‐rate late‐onset escalators, initially high‐rate desisters, and high‐rate chronic offenders. Multivariate regression models demonstrated that Hispanic immigrants were significantly less likely to be initially high‐rate desisters or high‐rate chronic offenders compared with their native‐born counterparts, yet unmarried Hispanics were significantly more likely to be high‐rate late‐onset escalators. Study limitations and implications are also discussed. 相似文献

Previous research examines the ecological relationship between income inequality and mortality, and results are inconclusive. This analysis builds upon these findings by implementing a spatially weighted path analysis to better understand the mediating relationships of economic and social inequality, health infrastructure, and mortality. In the analysis, overall and race-specific mortality rates are combined with local health infrastructure data, income inequality and racial segregation data, and a series of ecological controls to undertake this examination. Ultimately, findings show that income inequality is a stronger determinant of mortality than is segregation, for whites and blacks, regardless of the existing health infrastructure. We also find racial disparities in the direct effect of local health infrastructure on mortality. In contrast to previous literature suggesting no association between income inequality and mortality after accounting for race and model sophistication, we argue that the significance of the relationship persists using race-specific, spatially weighted path models. 相似文献

We address two views from organization theory to consider the expansion and effects of nonprofits in education: first, a functional view emphasizing the direct effect of work of civil society organizations (CSOs) and, second, a phenomenological neoinstitutional view focusing on the cultural meaning of education CSOs as indicators of a rationalized, liberal world society. We use panel regression models with country fixed effects to analyze the cross-national expansion of domestic education CSO sectors in 130 countries from 1970 to 2014. We then examine the association between the size of the domestic education CSO sector and memberships in international non-governmental organizations (INGOs) with education outcomes, including spending, education aid, secondary and tertiary enrollments, and the share of women in secondary and tertiary education. Results show that INGO memberships, an expanded state, and an expanded education system are highly associated with the expansion of a domestic education CSO sector. Both domestic CSOs and INGO memberships tend to have a significant, positive relationship with education outcomes net of other factors. We also find preliminary evidence indicating that the causal forces at play are more complex than a straightforward direct effect of education CSOs doing good work. Specifically, CSOs, at least in part, are indicators of a Western, liberal model of a proper modern society; the underpinning culture, represented by CSOs, accounts for some educational expansion above and beyond the benefit (or harm) caused by any given entity. 相似文献
