Introduction: Accountability in Neuroethics

Pharmaceutical sponsored clinical trials, formerly conducted predominantly in the United States and Europe, have expanded to emerging regions, including the Middle East. Our study explores factors influencing clinical trial privacy and confidentiality in the United Arab Emirates. Factors including concept familiarity, informed consent compliance, data access, and preservation, were analyzed to assess current practices in the Arab world. As the UAE is an emerging region for clinical trials, there is a growing need for regulations related to data confidentiality and subject privacy. Informational and decisional privacy should be viewed within the realms of Arab culture and religious background.     

Streetwise sales and the social order of city streets

This paper analyses how a Big Issue vendor approached passers-by and how they responded, how recognizable courses of social and economic activity were interactionally produced from initiation through to some conclusion. The paper recovers how the vendor's work was contextually embedded in the urban landscape, how it was constrained by, and actively shaped, the social order of the street. Drawing on video-audio recordings the paper contributes to a growing body of ethnographic and ethnomethodological research which has emphasized the embodied, contingent and interactional character of economic activity. By examining such materials, the paper is well positioned to describe how the vendor found his market on the street, social interventions that propelled passers-by into buying behaviour. The paper sheds light on now familiar encounters which occur millions of times each week in the UK and beyond.     

Comparability of the 6-min walk test using different test configurations

The 6-min walk test (6MWT) is a common component of fitness assessments of older adults; however, differing course configurations might affect 6MWT performance. It is unclear how comparable 2 different configurations are. To determine the comparability of 2 courses, 35 adults >65 years of age completed two 6MWT, once walking around a 20- by 5-yd outdoor rectangle and once on an indoor oval track (circumference 144.3 yd). Scores for the 2 tests were internally consistent (intraclass correlation coefficient = .95). The participants walked farther on the oval track than around the rectangle (639 +/- 19 vs. 582 +/- 16 yd; p < .0001), but responses to the rectangular configuration could be readily estimated using the equation 66.7 yd + 0.807 x (oval walking distance), R2 = .85. Thus, within-participant responses are similar across both 6MWT, but the course configuration affects the distance walked.     

AN INTERNATIONAL COMPARISON OF LIFETIME INEQUALITY: HOW CONTINENTAL EUROPE RESEMBLES NORTH AMERICA

We compare earnings inequality and mobility across the United States, Canada, France, Germany and the United Kingdom during the late 1990s. A flexible model of earnings dynamics that isolates positional mobility within a stable earnings distribution is estimated. Earnings trajectories are then simulated, and lifetime annuity value distributions are constructed. Earnings mobility and employment risk are found to be positively correlated with base‐year inequality. Taken together they produce more equalization in countries with high cross‐section inequality such that the countries in our sample have more similar lifetime inequality levels than cross‐section measures suggest.     

Age-Specific Death Rates With Tobacco Smoking and Occupational Activity: Sensitivity to Sample Length,Functional Form,and Unobserved Frailty

In this article, we estimate accelerated time-to-failure and proportional-hazard functions with about 100,000 members of the Dorn sample, finding greater hazards associated with smoking and some dependence on occupational variables that measure risk and physical activity. We answer three questions: (1) How sensitive are the estimates to sample length, using monthly data for the periods 1954–1969 and 1954–1980? The results differ somewhat between these sample periods. (2) How sensitive are the estimates to alternative functions for the hazard? Within a given time period, the estimates are fairly robust to specification changes in the distribution of the hazard in the accelerated time-to-failure models. (3) How sensitive are the estimates to alternative controls for unobserved frailty? Within a given sample period, the estimates are fairly robust to the allowance for parametric or nonparametric heterogeneity in the proportional-hazard models.     

Valuation of education and crime neighborhood characteristics through hedonic housing prices

This article studies households' valuation of neighborhood amenities through analysis of housing as a bundle of structural and neighborhood characteristics. Using statistical techniques, hedonic prices, or incremental values in the market, can be imputed to each element of the bundle. Twelve variables describe neighborhood crime; twenty-one variables describe neighborhood schools. Together with structural variables, they significantly and substantially explain house prices in the Baltimore metropolitan area. The technique is also shown to provide a market framework for approximating the benefits of localized neighborhood improvements.The authors wish to thank David Puryear, Ralph Taylor, and the two anonymous referees for their helpful comments on earlier drafts of this paper. We also thank Central Maryland Multiple Listing Service, the Baltimore City and Baltimore County Police Departments, and the Johns Hopkins Center for the Social Organization of Schools for house price, crime, and education data. None of the people or organizations listed is in any way responsible for the analyses or conclusions presented. Requests for reprints should be addressed to Dr. Allen C.

An international classification system for child welfare programs

A major challenge in child welfare is whether a program (or service) developed and successfully implemented in one jurisdiction, especially another country, will attain the same outcomes for children and families in another jurisdiction? This paper presents the “DCE Classification System” (Defining, Classifying, and Evaluating), a classification system that facilitates cross-jurisdiction comparisons of child and family services. The paper reviews the cross-national research literature in child and family services as well as literature on classification schemes and typologies. As an example of the issues that arise when importing a promising program, we briefly highlight the exporting and importing of family group conferencing. After tracing the history and development of the DCE Classification System, the paper describes the proposed classification scheme, and provides a brief example of how researchers and practitioners can use the classification system for cross-national comparisons of client outcomes and program costs. Finally, we discuss the strengths and weaknesses of this approach, as well as possible benefits for child and family practices.     

An experiment to test the feasibility and quality of a web-based questionnaire of teachers

The use of web-based surveys to gather information from teachers has become increasingly common primarily based on the premise that they can reduce costs. Yet, relatively, little is known about the quality or cost effectiveness of web-based versus mail surveys for teachers. To study the efficacy of web-based teacher surveys, the author randomly assigned a nationally representative sample of 877 elementary school teachers to a paper or web survey mode. The cost savings from the web administration were not enough to offset the loss of sample due to missing/inaccurate email addresses and the lower response rates that resulted from the web survey.
