Associations between air pollution and cardio-respiratory physiological measures in older adults exercising outdoors.

We examined whether exercising indoors vs. outdoors reduced the cardio-respiratory effects of outdoor air pollution. Adults ≥55 were randomly assigned to exercise indoors when the Air Quality Health Index was ≥5 and outdoors on other days (intervention group, n = 37), or outdoors everyday (control group, n = 35).

Science for Policy: A Case Study of Scientific Polarization, Values, and the Framing of Risk and Uncertainty.

It is well documented that more research can lead to hardened positions, particularly when dealing with complex, controversial, and value-laden issues. This study is an attempt to unveil underlying values in a contemporary debate, where both sides use scientific evidence to support their argument. We analyze the problem framing, vocabulary, interpretation of evidence, and policy recommendations, with particular attention to the framing of nature and technology.

Interfering with therapeutic tranquility: Debates surrounding biosolid waste processing in rural Ontario.

Uncertainty surrounding potential health effects of techno-industrial facilities continues to result in heightened debate about what are the best and safest options for future generations in rural places regarded by residents for their therapeutic tranquility. This research examines how a proposed biosolid processing facility in rural Ontario producing agricultural fertilizer from primarily urban sewage has in some residents elicited particularly strong concerns about potential health impacts, which are accompanied by perceptions that the tranquil and pastoral nature of their landscape is being altered. However, fueling community conflict between friends and relatives is the contested nature of the landscape's restorative qualities and the facility's disruption of this tranquil place.
