Sustainable landscaping programs in the United States and their potential to encourage conservation and support ecosystem services

Sustainable landscaping programs are voluntary initiatives that recommend a set of practices to improve the environmental quality of urban ecosystems by providing landscaping materials, guidelines, and educational resources. Our goal was to examine the recommendations and outcomes of these programs in the United States and their value for encouraging conservation practices in residential ecosystems. We conducted a comprehensive web search and identified 193 sustainable landscaping programs in the United States. Programs aim to increase native species richness, affordably manage stormwater runoff, and offer residents meaningful experiences with nature. Sustainable landscaping programs present many opportunities to engage people with local ecological knowledge and conservation practices, provide accessible spaces for environmental education, cultivate interdisciplinary research collaborations, and advance inclusion in conservation. However, assessments of their ecological value are rare, leaving many questions surrounding the benefits to biodiversity and water quality afforded by participation. Many programs also require investments in landscaping materials and certification fees that might limit participation by some households. Future work should examine how recommended practices influence urban biodiversity, identify and address barriers to participation, and generate social-ecological knowledge that can inform future programs.

     

Political Orientations and Naturalization Among Latino and Latina Immigrants*

Objective. This study adds to our knowledge of the naturalization process by considering the impact of political orientations in shaping the pursuit of U.S. citizenship among contemporary Latino and Latina immigrants. Methods. We draw on data from the 1999 Harvard/Kaiser/Washington Post “Latino Political Survey” and use ordered logistic regression analyses to test the effects of political orientations on immigrant naturalization. Results. Political orientations exert a powerful influence on naturalization beyond the traditional sociodemographic determinants. Furthermore, the impact of political orientations on naturalization varies by gender. Conclusions. Naturalization can be induced by stressing the importance of voting and being interested in politics. In addition, Latinas are more likely to pursue naturalization than Latinos and the factors driving their decisions systematically differ from those of their male counterparts.     

The Continuing Dominance of Traditional Gender Roles in Southern Elections*

Objective. Studies of the election of women to public office have been increasingly encouraging about their prospects of female candidates. The purpose of this study is to examine the extent to which gender roles continue to influence the election of women to local office and the pool of candidates for higher office. Methods. Utilizing data on the gender of officials, the nature of the office, and constituency demographics from county elections in eight Southern states, we construct logit models of the election of women. Results. Women hold few local offices involved in fighting crime or of an executive nature. On the other hand, women routinely win election to process‐oriented offices with less discretion. Our analysis of constituency demographics reinforces our conclusions. Women win election in areas where the public office is relatively undesirable compared to other opportunities and the ratio of high‐quality male to high‐quality female candidates is relatively low. Conclusions. Although the frequent election of women to county office provides an expanded pool of female candidates for higher offices, it seems unlikely that women will find it as easy to move up the electoral ladder into the more competitive arena of high‐profile statewide and federal leadership offices.     

Involvement of Ministries of Health in Health Service Coverage Decisions: Is England an Aberrant Case?

This article examines the involvement of ministries of health in making health service coverage decisions in Denmark, England, France and Germany. The study aims to inform debate in England about the feasibility of reducing perceived ministerial and bureaucratic ‘interference’ in decisions affecting the National Health Service, based on interviews with senior government officials and other health system stakeholders. Ministries of health differ in their involvement in health system governance and coverage decisions (‘the benefits package’), reflecting differences in institutional arrangements. In all four countries, organizations at arm's length or independent from government are either involved in providing technical advice to the ministry of health or have been mandated to take these decisions themselves. However, ministries of health occasionally intervene in the decision‐making process or ignore the advice of these organizations. The Department of Health in England is not an aberrant case, at least in relation to coverage decisions. Indeed, ministries of health in Denmark and France play a larger role in making these decisions. Public pressure, often amplified by the media, is a shared reason for ministerial and ministry involvement in all four countries. This dynamic may thus limit the feasibility of attempts to further separate the NHS from both the Department of Health and wider political pressures.     

A Preliminary Investigation of a Telephone Administration of the Quality of Marriage Index

Follow‐up data collection presents many challenges for longitudinal research. Validating paper‐and‐pencil assessments for use via telephone may alleviate these issues. This study evaluates psychometric properties of the Quality of Marriage Index (QMI; Norton, 1983, Journal of Marriage and the Family, 45, 141) when administered by telephone and compares scores with the paper‐and‐pencil version. Participants included women with major depressive disorder and dyadic discord and their male spouses (n = 24 couples). Results suggest excellent scale reliability for the verbal QMI. However, a significant mean difference was found: participants scored on average 3 points higher on the telephone‐administered QMI than on the written QMI. Recommendations for future research and clinical implications are discussed.     

Unconditional pseudo-maximum likelihood and adaptive estimation in the presence of conditional heterogeneity of unknown form

We consider parametric non-linear regression models with additive innovations which are serially uncorrelated but not necessarily independent, and consider the consequences of maximum likelihood and related one-step iterative estimation when the innovations are treated as being iid from their unconditional density. We find that the estimators' asymptotic covariance matrices will generally differ from those that would obtain if the errors actually were iid, except for the special case of strictly exogenous regressors. One important application of these results is to analysis of the properties of adaptive estimators, which employ nonparametric kernel estimates of the unconditional density of the disturbances in the construction of one-step iterative estimators. In the presence of strictly exogenous regressors, adaptive estimators are found to be asymptotically equivalent to the one-step iterative estimators that use the correct unconditional density. We illustrate our results through a brief Monte Carlo study.     

The Impact of Migration on the Gendering of Service Work: The Case of a West London Hotel

This article responds to a call from Kerfoot and Korczynski to investigate the gendering of service sector employment. As a characteristic of many post‐industrial economies in the global North is the growing significance of migrant workers, this article investigates the impact of migration for work on the gendering of service work. Taking the embodied and emotional labour of workers to be fundamental to service work, it describes how these are refracted and produced through migration. The article draws on 60 interviews with workers in a west London hotel who were born abroad and the human resources staff and managers who are responsible for the recruitment and promotion of the workforce. We argue that migration is an important process in the construction of the contemporary workforce in post‐industrial service economies and that migration status should be understood as intersecting with gender in the production of a gendered performance at work.
