How do variations in Urban Heat Islands in space and time influence household water use? The case of Phoenix, Arizona
No full textabstract: This paper explores how urbanization, through its role in the evolution of Urban Heat Island (UHI), affects residential water consumption. Using longitudinal data and drawing on a mesoscale atmospheric model, we examine how variations in surface temperature at the census tract level have affected water use in single family residences in Phoenix, Arizona. Results show that each Fahrenheit rise in nighttime temperature increases water consumption by 1.4%. This temperature effect is found to vary significantly with lot size and pool size. The study provides insights into the links between urban form and water use, through the dynamics of UHI.Corresponding Author:

Myositis Basics/Who Gets Myositis
No full textThe idiopathic inflammatory myopathies (IIM), often referred to collectively but less specifically as “myositis,” have an estimated prevalence of ~14 per 100,000 with an annual incidence of ~8 per 1,000,000 population, which appears to be increasing over time. Any age group can be affected, but myositis commonly presents between 30 and 60 years of age. Differences are seen based on autoantibody subtypes as, for example, anti-signal recognition particle (SRP) seems more common in younger adults. Females are affected about twice as often as males, but again there are important differences when considering specific clinical subtypes as inclusion body myositis (IBM) is more common in males. Current research is focussed on understanding the complex interactions between genetic susceptibility and exposures to environmental triggers. The majority of genetic risk factors identified to date lie within the major histocompatibility complex (MHC), a region which contains genes responsible for antigen presentation, but a small number of genetic risk factors have been found outside this region and implicated in innate and adaptive immune functions. Important environmental associations have been already identified, including exposures to ultraviolet radiation, smoking and certain medications such as statins
