In order to update candidate evaluations voters must acquire information and determine whether that new information supports or opposes their candidate expectations. Normatively, new negative information about a preferred candidate should result in a downward adjustment of an existing evaluation. However, recent studies show exactly the opposite; voters(More)
The Tropospheric ORganic CHemistry experiment (TORCH) took place during the heatwave of summer 2003 at Writtle College, a site 2 miles west of Chelmsford in Essex and 25 miles north east of London. The experiment was one of the most highly instrumented to date. A combination of a large number of days of simultaneous, collocated measurements, a consequent(More)
The PUMA (Pollution of the Urban Midlands Atmosphere) Consortium project involved intensive measurement campaigns in the Summer of 1999 and Winter of 1999/2000, respectively, in which a wide variety of air pollutants were measured in the UK West Midlands conurbation including detailed speciation of VOCs and major component analysis of aerosol.

OBJECTIVES To evaluate a mass media campaign to reduce the consumption of sugar-sweetened beverages (SSBs). METHODS We disseminated messages emphasizing the health risks of SSBs through television, digital channels, and local organizations over 15 weeks in 2015-2016 in the Tri-Cities region of northeast Tennessee, southwest Virginia, and southeast(More)
A Lagrangian trajectory model used to simulate photochemistry has been extended to include a simple parameterisation of primary and secondary aerosol particles. The model uses emission inventories of primary particles for the UK from the NAEI (National Atmospheric Emissions Inventory for the UK), and for Europe from the TNO (Institute of Environmental(More)
