In the United States, falls are the leading cause of unintentional death with one of every three people 65 years and older falling each year. Falls account for approximately 95% of hip fractures among older adults and falls to the side predominate hip fracture related falls in this population. However,...
The use of fossil fuels and their related impact on the environment and global warming have encouraged societies to pursue more sustainable and renewable alternatives, e.g., forest-based bio-oil. Thus, a vital need to decrease the level of greenhouse gas emissions and the tendency of nations to reduce their dependency on...
The use of native plants in restoration and afforestation has increased worldwide as their benefits to habitat quality, ecosystem services and local community well-being become widely known. In many restoration and afforestation sites, the most cost-effective and efficient way to establish plants is to use seedlings. Unfortunately, there is a...
Title: African-American Women Faculty Teaching at Institutions of Higher Learning in the Pacific Northwest: Challenges, Dilemas, and Sustainability
Institutions of higher learning in the Pacific Northwest have successfully recruited African-American faculty, yet these institutions have difficulty retaining African-American faculty for at least five years. African-American women faculty experience problems obtaining...
Nutrient limitation constrains tree growth in many managed forests. Nitrogen (N) is the most common limiting nutrient, but high N supply can shift limitation to other nutrients, particularly phosphorus (P) and the base cations calcium (Ca), magnesium (Mg), and potassium (K). As different soil minerals have different capacities to supply...
Treating styroblock containers in hot water (68°C) with a very dilute bleach and detergent solution effectively reduced populations of Fusarium and Cylindrocarpon spp., two potential root pathogens of containerized conifer seedlings. However, the treatment did not significantly reduce levels of Phoma (another potential pathogen) nor saprophytic Penicillium and Alternaria spp....
Recent catastrophic wildfires have forced the forest management community to develop new strategies for reducing forest fuels. Tightly spaced understory trees often create a fire ladder allowing surface fires to encroach into the crowns of overstory trees. This situation can lead to intensive, catastrophic, stand-replacement forest fires. Mechanical removal or...
The purpose of this study was to analyze and interpret the results
of fall term student ratings of faculty teaching performance (n= 40,000)
in order to determine whether relationships exist between a range of
demographic variables and the ratings professors receive from students
enrolled in their classes. A population of...
During October 2000 the Po River, Italy's largest river, experienced a historically significant flood, producing a deposit on the adjacent prodelta. In December 2000 an event-response study of the deposit was conducted, and during the ensuing 16 months three additional sampling cruises were conducted to study the subsequent evolution of...
