BACKGROUND: Interventions to promote physical activity (PA) in children attending family child care homes (FCCHs) require valid, yet practical, measurement tools. The aim of this study was to assess the validity of two proxy report instruments designed to measure PA in children attending FCCHs. METHODS: A sample of 37 FCCH...
This has been a banner year for open access, and the momentum shows no sign of letting up. College and university faculties, and the granting agencies that fund a significant amount of their research, are increasingly embracing open access to ensure research findings across disciplines are freely accessible to the...
A systems trial was established in Oct. 2006 to evaluate management practices for organic production of northern highbush blueberry (Vaccinium corymbosum L.). The practices included: flat and raised planting beds; feather meal and fish emulsion fertilizer each applied at rates of 29 and 57 kg·ha⁻¹ nitrogen (N); sawdust mulch, compost...
Accurate quantification of terrestrial carbon storage and its change is of key importance to improved understanding of global carbon dynamics. Forest management influences carbon sequestration and release patterns, and gap models are well suited for evaluating carbon storage. An individual-based gap model of forest dynamics, FAREAST, is applied across Russia...
Inhaled and intranasal corticosteroids (ICS and INS) are among the mainstays of the treatment for asthma and allergic rhinitis, respectively, and also carry the potential to suppress the hypothalamic–pituitary–adrenal (HPA) axis. Several important factors affect the interpretability of trials investigating the impact of ICS and INS on the HPA axis....
The utility of the fatty acid biomarker (FAB) approach in fisheries ecology is limited by our understanding of how biotic and abiotic factors determine dietary markers in fish tissues. An 8-week laboratory experiment was conducted on two species of juvenile gadids (Pacific cod, Gadus macrocephalus and walleye Pollock, Theragra chalcogramma)...
OBJECTIVES: To improve understanding of factors that may influence disclosure of complementary and alternative medicine (CAM) use in the U.S.
DESIGN: Cross-sectional survey.
METHODS: Data are from the 2001 Health Care Quality Survey (HCQS), a nationally representative study of adults aged 18 and older living in the continental United States....
The spectrum of the interior transmission problem is related to the unique determination of the acoustic properties of a body in thermoacoustic imaging. Under a non-trapping hypothesis, we show that sparsity of the interior transmission spectrum implies a range separation condition for the thermoacoustic operator. In odd dimensions greater than...
BACKGROUND: The illicit use of prescription stimulants (IUPS) has emerged as a high-risk behavior of the 21st century college student. As the study of IUPS is relatively new, we aimed to understand 1) characteristics of IUPS (i.e., initiation, administration routes, drug sources, motives, experiences), and 2) theory-guided intrapersonal, interpersonal, and...
Context: Antibiotic prescribing in hospice patients is complicated by the focus on palliative rather than curative care and concerns regarding increasing antibiotic resistance.
Objective: To estimate antibiotic use in a national sample of hospice patients and identify facility and patient characteristics associated with antibiotic use in this population.
Methods: This...
Irrigation percolation can be an important source of shallow aquifer replenishment in arid regions of the southwestern United States. Aquifer recharge derived from irrigation percolation can be more significant in fluvial valleys overlying shallow aquifers where highly permeable soils allow rapid water infiltration and aquifer replenishment. We used data from...
The genome sequence of a baculovirus from Hemileuca sp. was determined. The genome is 140,633 kb, has a G+C content of 38.1%, and encodes 137 putative open reading frames over 50 amino acids. 126 of these ORFs showed similarity to other baculovirus genes in the database including all 37 core...
The significance of the various carbon cycling pathways in driving the sharp sulfate methane transition (SMTZ) observed at many locations on continental margins is still a topic of debate. Unraveling these processes is important to our understanding of the carbon cycle in general and to evaluate whether the location of...
Regeneration of the Earth’s magnetic field by convection in the liquid core produces a broad spectrum of time variation. Relative palaeointensity measurements in marine sediments provide a detailed record over the past 2 Myr, but an explicit reconstruction of the underlying dynamics is not feasible. A more practical alternative is...
Viruses and/or virus-like selfish elements are associated with all cellular life forms and are the most abundant biological entities on Earth, with the number of virus particles in many environments exceeding the number of cells by one to two orders of magnitude. The genetic diversity of viruses is commensurately enormous...
Model–data comparisons of plant physiological processes provide an understanding of mechanisms underlying vegetation responses to climate. We simulated the physiology of a pi~non pine–juniper woodland (Pinus edulis–Juniperus monosperma) that experienced mortality during a 5 yr precipitation-reduction experiment, allowing a framework with which to examine our knowledge of drought-induced tree mortality....
Light availability strongly influences stream primary production, water temperatures and resource availability at the base of stream food webs. In headwater streams, light is regulated primarily by the riparian forest, but few studies have evaluated the influence of riparian forest stand age and associated structural differences on light availability. In...
Youth depression is a significant and growing international public health problem. Youth who engage in high levels of delinquency are at particularly high risk for developing problems with depression. The present study examined the impact of a behavioral intervention designed to reduce delinquency (Multidimensional Treatment Foster Care; MTFC) compared to...
In August 2011, a cohort of 30 Oregon State University Libraries and Press librarians and staff received free e-readers (Kindle Keyboards, Nook Simple Touches, Kobo Touches, and Sony PRS-350 Reader Pocket Editions) to use and adopt as they wished. In return, they were asked to participate in a year-long study...
Climate change models predict that future precipitation patterns will entail lower-frequency but larger rainfall events, increasing the duration of dry soil conditions. Resulting shifts in microbial C cycling activity could affect soil C storage. Further, microbial response to rainfall events may be constrained by the physiological or nutrient limitation stress...
