Street Audits to Measure Neighborhood Disorder: Virtual or In-Person?

Neighborhood conditions may influence a broad range of health indicators, including obesity, injury, and psychopathology. In particular, neighborhood physical disorder - a measure of urban deterioration - is thought to encourage crime and high-risk behaviors, leading to poor mental and physical health. In studies to assess neighborhood physical disorder, investigators typically rely on time-consuming and expensive in-person systematic neighborhood audits. We compared 2 audit-based measures of neighborhood physical disorder in the city of Detroit, Michigan: One used Google Street View imagery from 2009 and the other used an in-person survey conducted in 2008. Each measure used spatial interpolation to estimate disorder at unobserved locations. In total, the virtual audit required approximately 3% of the time required by the in-person audit. However, the final physical disorder measures were significantly positively correlated at census block centroids (r = 0.52), identified the same regions as highly disordered, and displayed comparable leave-one-out cross-validation accuracy. The measures resulted in very similar convergent validity characteristics (correlation coefficients within 0.03 of each other). The virtual audit-based physical disorder measure could substitute for the in-person one with little to no loss of precision. Virtual audits appear to be a viable and much less expensive alternative to in-person audits for assessing neighborhood conditions

MicroBooNE is the first phase of the Short Baseline Neutrino program, located at Fermilab, and will utilize the capabilities of liquid argon detectors to examine a rich assortment of physics topics. In this document details of design specifications, assembly procedures, and acceptance tests are reported

The equity debate within the British National Health Service

The equity debate within the British National Health ServiceThis paper begins by identifying the principles of equity and fairness on which the British National Health Service (NHS) was founded in 1948. It then goes on to summarize the viewpoints of those who more recently have argued that equity is an out-moded, Utopian and unachievable concept that should not be applied to the delivery of health care services. A brief review is conducted of the definitions of equity and inequity as these apply to health care. Brief attention is paid to the relationship between equitable distribution of health care and social class. The new contemporary significance of equity for all NHS managers is exposed through a debate concerning the impact of the recently introduced policies for the implementation of a quasi-market in health services in Britain. The inseparable relationship between equity and the rationing of resources is identified as central to the just distribution of health care. The paper presents evidence that the quasi-market solutions to improved economic efficiency and cost-containment are often in direct conflict with the equity doctrine on which the NHS was created. A brief conclusion how equity principles might be restored to health policy is proffered
