Studies on types and impacts of crime have indicated that crime and violent acts do occur on public lands and have negative consequences for managers of those lands and recreation visitors. It is important, then, to evaluate how to reduce or eliminate crime and violent acts on public lands. To...
Using a qualitative approach, the authors tested a crime
typology developed for tourism destinations in a U.S. National
Forest recreation setting. Specific objectives were to
classify the attributes of crime and violence, examine the effects
of crime and violence on visitor demand, and suggest
methods of prevention and recovery. A...
The aim of this article is to explain why research focusing on crime and violence on national forests is necessary and overdue. Four questions are offered to frame future research. First, how much crime is occurring on national forests, and how can the effects of crime and violence best be...
Mechanical thinning and prescribed fire are widely used to restore western forests after a century of fire suppression, yet we know little about how these treatments affect understory communities where plant diversity is highest. We followed understory plants and environmental factors in old-growth, Sierran mixed conifer for two pre-treatment and...

Biosolids are a by-product of municipal wastewater treatment. They contain organic matter and nutrients that are beneficial for soil, crop, and livestock productivity. Raw sewage solids must be processed to meet U.S. Environmental Protection Agency (USEPA) standards before they can be called biosolids. This publication focuses on how biosolids can...

The Generation Challenge programme (GCP) is a global crop research consortium directed toward crop improvement through the
application of comparative biology and genetic resources characterization to plant breeding. A key consortium research activity
is the development of a GCP crop bioinformatics platform to support GCP research. This platform includes the...

As in various freshwater and coastal marine ecosystems worldwide, seasonal bottom water hypoxia is a recurring phenomenon in Lake Erie's central basin. While bottom hypoxia can strongly affect sessile benthic animals, its effects on mobile organisms such as fish are less understood. We evaluated the potential for bottom hypoxia to...
Oregon’s forested coastal watersheds support important cold-water fisheries of salmon
and steelhead (Oncorhynchus spp.) as well as forestry-dependent local economies. Riparian
timber harvest restrictions in Oregon and elsewhere are designed to protect stream habitat
characteristics while enabling upland timber harvest. We present an assessment of riparian
leave tree rule effectiveness...
We find contagion effects are present in US small size portfolios during emerging market crises due to risk and liquidity concerns. Investors display flight from risk during emerging market crises, and as a result, safer larger stocks exhibit positive abnormal returns. We find little evidence of contagion in aggregate excess...
