In this paper, we address the often contentious debate over state and local recycling policy by carefully estimating the social net benefit of curbside recycling. Benefits are estimated using household survey data from over 4,000 households across 40 western U.S. cities. We calibrate household willingness-to-pay for hypothetical bias using an innovative experimental design that contrasts stated...

The effect of elevation and rooftop configuration on local air quality was investigated at the Brooklyn Grange rooftop farm during a short-term observational campaign. Using multiple particle counters and sonic anemometers deployed along vertical gradients, we found that PM2.5 concentration decayed with height above the street. Samples adjacent to the street had the highest average PM2.5 concen...

background: glaucoma is one of the most common causes of blindness and is usually associated with elevated intraocular pressure. in patients with primary open angle glau-coma the number of trabecular meshwork cells is decreased. death of the trabecular meshwork cells may be a result of apoptosis. objective: to investigate the aqueous humor levels of soluble fas (sfas) and fas-ligand (sfasl) in ...

Curbside recycling is costly and performs poorly on expected environmental economic outcomes. This raises the question of whether curbside should endure or be eliminated to allow alternative services flourish.

Recycling has been touted as an important part of the solution to solid waste problems, yet most citizens still do not recycle, even when recycling is made easy by curbside pickups. This field experiment was designed to increase participation in a citysponsored curbside recycling program. Citizens who consistently recycled with the city program were approached and asked to be "recycling block l...

Improper waste disposal and management globally is linked to a variety of problems with the environment and health. This problem can be addressed by following the 3 R’s; reduce, reuse, and recycle. Japan is continually aiming towards becoming a sustainable, recycling oriented society with the implementation of the 3 R’s, reducing GHG emissions, and innovating new technologies for recycling and ...

Local authorities throughout the UK are refining or implementing curbside recycling schemes as they attempt to achieve challenging statutory recycling targets. Despite the importance of curbside schemes there are few published studies that have reported on actual measured levels and frequency of participation by residents, hindering transferability of lessons learned nationally and internationa...
