A large body of evidence suggests physical activity is inversely associated with
several cardio-metabolic risk factors among children and adolescents. Despite these
health benefits, a majority of youth are not meeting the physical activity guidelines set
forth by the USDHHS. Schools have been identified as an ideal vehicle for interventions;...
BACKGROUND: Parents play a significant role in shaping youth physical activity (PA). However, interventions targeting PA
parenting have been ineffective. Methodological inconsistencies related to the measurement of parental influences may be a
contributing factor. The purpose of this article is to review the extant peer-reviewed literature related to the measurement...
Machine learning models are powerful tools which may aid in the prediction of survival outcomes of cancer patients. This study evaluated eight classification models and eight regression models on their ability to predict survival outcomes on breast cancer and prostate cancer data sets from the SEER database. The most accurate...
The release of transgenes into the environment by transgenic plant species is a significant ecological concern, and consequently a containment method for these genetically modified organisms is highly sought after. For poplar trees, an option for containment is to produce trees that do not flower and therefore cannot spread genetic...

Agonistic behavior among three species of Microtus live-trapped
near Corvallis, Oregon was recorded in order to interpret habitat
segregation by the species in areas of syrnpatry. The method used to
measure agonistic interaction was similar to that of Colvin (1970).
Agonistic behavior was recorded under red light in a neutral...
Exposure assessment is necessary to determine the frequency and magnitude of environmental contaminants, especially since exposure may lead to adverse health outcomes. Traditional personal exposure assessment tools such as biological samples are limited in their ability to capture a wide range of chemical exposures from a single sample, and others...
During the past two decades, interest has grown in the role and welfare implications of different head and neck positions (HNPs) in equine biomechanics as well as dressage training and competition. To evaluate the influence of HNP on stride length, 17 horses of varying breeds and dressage levels were studied...
Population and habitat characteristics of Acorn Woodpeckers
(Melanerpes formicivorus) were examined in oak stands (Quercus
garryana) in Benton County, Oregon. Characteristics of eight oak
stands not containing Acorn Woodpeckers were also examined. The
data were used to determine which factors might be related to woodpecker
presence and abundance within the...
The vegetation surrounding a nest shades and insulates the incubating
bird in addition to concealing it. The vegetative material
that makes up a nest insulates the eggs from its warmer or cooler
surroundings. Since a Killdeer builds a stone-lined nest on barren
ground, both egg and adult are subject to...
Intensive observations were made of play behavior in the
young hamster (Mesocricetus auratus) from 14 to 54 days of age.
Behavior was recorded using movie film and a multi-channel event
recorder.
Play was first seen at 14 days of age. The amount of play
increased rapidly thereafter, remaining relatively high...
