Ethnic ghettos in Britain: a fact or a myth?

A common claim is that Britain's minorities live isolated "parallel lives" in inner cities that have become ethnic ghettos. Does the evidence confirm such dangerous lack of integration? Ludi Simpson and Nissa Finney find a basic misunderstanding about population change—a misunderstanding that makes changing the ethnic mix of neighbourhoods an unrealistic policy goal.     

Mitigating the Combined Distributional Consequences of the Georgia Lottery for Education and the HOPE Scholarship*

Objective. Research demonstrates that nonwhite, lower‐income households bear the Georgia Lottery's tax burden, yet receive fewer benefits. However, local disparities in grading standards may mitigate the observed income redistribution. Our objective is to determine whether certain localities obtain more HOPE scholarships than expected, mitigating the observed redistribution. Method. We use fixed‐effects regression and a sample of Georgia's counties (1996–2002). Results. Our results indicate that some localities obtain more HOPE scholarships than expected, mitigating the observed redistribution. Conclusions. We conclude the income‐redistribution research result does not reveal a complete picture because it overlooks the HOPE scholarship's extraordinary allocation mechanism.     

Rating methodological quality: toward improved assessment and investigation

Assessing methodological quality is considered essential in deciding what investigations to include in research syntheses and in detecting potential sources of bias in meta-analytic results. Quality assessment is also useful in characterizing the strengths and limitations of the research in an area of study. Although numerous instruments to measure research quality have been developed, they have lacked empirically-supported components. In addition, different summary quality scales have yielded different findings when they were used to weight treatment effect estimates for the same body of research. Suggestions for developing improved quality instruments include: distinguishing distinct domains of quality, such as internal validity, external validity, the completeness of the study report, and adherence to ethical practices; focusing on individual aspects, rather than domains of quality; and focusing on empirically-verified criteria. Other ways to facilitate the constructive use of quality assessment are to improve and standardize the reporting of research investigations, so that the quality of studies can be more equitably and thoroughly compared, and to identify optimal methods for incorporating study quality ratings into meta-analyses.     

Slippery discrimination: a review of the drivers of migrant and minority housing disadvantage

ABSTRACT

This paper aims to identify housing disadvantages faced by migrants and ethnic minorities; the legal, policy and market forces that shape them; how they have developed over time; how they are manifest nationally and locally; and how they are being responded to locally by those concerned with mitigating them. The paper thereby intends to provide a foundation to inform future research and policy and to engage with local actors to develop ways of overcoming migrant housing disadvantage and challenging discrimination. The paper finds that the interplay of legal changes, which have increasingly differentiated migrants since the 1940s, and shifting housing markets, has driven exclusion of migrants and minorities such that considerable disadvantage is revealed by analysis of census data. However, attention to local specificity provides evidence of positive responses. Examples are presented in relation to access to affordable housing, enactment of homelessness duties and community actions. Methodologically, this paper highlights the importance of simultaneous consideration of migration and ethnicity as markers of difference and exclusion, and the potential of co-production approaches for socially meaningful research concerned with inequalities.     

Environmental assessment and evaluation research: examples from mental health and substance abuse programs.

Evaluation researchers have been broadening the traditional client input--"black box" treatment--client outcome paradigm that has guided many evaluations of mental health, substance abuse treatment, and other intervention programs. The points of expansion are in the areas of treatment implementation and treatment processes, as well as "extratreatment" influences on treatment selection, duration, and, especially, outcome. This review illustrates the application of environmental assessment procedures--particularly social climate measures--in four aspects of evaluation research suggested by the more comprehensive model: (a) evaluating treatment implementation; (b) exploring treatment processes; (c) identifying extratreatment influences on client posttreatment functioning; and (d) operationalizing outcome variables. Conceptual and methodological issues raised by these applications are discussed, and the benefits to be derived from an expanded model of evaluation research--especially the greater potential for program improvement--are considered.     

Assessing Climate Change Impacts on Wildfire Exposure in Mediterranean Areas

We used simulation modeling to assess potential climate change impacts on wildfire exposure in Italy and Corsica (France). Weather data were obtained from a regional climate model for the period 1981–2070 using the IPCC A1B emissions scenario. Wildfire simulations were performed with the minimum travel time fire spread algorithm using predicted fuel moisture, wind speed, and wind direction to simulate expected changes in weather for three climatic periods (1981–2010, 2011–2040, and 2041–2070). Overall, the wildfire simulations showed very slight changes in flame length, while other outputs such as burn probability and fire size increased significantly in the second future period (2041–2070), especially in the southern portion of the study area. The projected changes fuel moisture could result in a lengthening of the fire season for the entire study area. This work represents the first application in Europe of a methodology based on high resolution (250 m) landscape wildfire modeling to assess potential impacts of climate changes on wildfire exposure at a national scale. The findings can provide information and support in wildfire management planning and fire risk mitigation activities.     

Theory and method in treatment evaluation

We outline a conceptual model of evaluation research that has both guided and flowed from our research on the process and outcome of treatment for alcohol abuse and for depression. The conceptual model encompasses three basic processes: the process of treatment selection, the process of treatment, and the process underlying the onset and course of the disorder or problem being treated. A theory guiding a program evaluation can focus on one or more of these processes, and findings from evaluations can contribute to the development of better theories of these processes. We discuss how theories can guide both experimental and naturalistic evaluations, as well as aid in the estimation of treatment effects with either type of design. We then consider the role of theory and method in exploring patient-treatment matching. Finally, we discuss the implications of theory-guidance for the utility of evaluations—particularly the utility for evaluation researchers.
