Social information is used widely in breeding habitat selection and provides an efficient means for individuals to select habitat, but the population-level consequences of this process are not well explored. At low population densities, efficiencies may be reduced because there are insufficient information providers to cue high-quality habitat. This constitutes...
Premise of research. A large pollen cone cluster attached to a cunninghamioid twig and surrounded by leaves has been identified from Eocene calcium carbonate marine concretions from the Appian Way locality on Vancouver Island, British Columbia, Canada. The cluster preserves 18 cones but probably bore at least 24 pollen cones...
This research develops a theoretical account of cultural meanings as integral mechanisms in the normalization of credit/debt. Analysis derives these meanings from the credit/debt discourses and practices of 27 white middle-class consumers in the United States and tracks their negotiation in patterns and trajectories in social and market domains. Discussion...
We performed a real-world, controlled intervention to investigate
use of an antimicrobial surface polymer, MSDS Poly, on environmental
contamination. Pathogenic bacteria were identified in 18
(90%) of 20 observations in treated rooms and 19 (83%) of 23
observations in untreated rooms (P = .67). MSDS Poly had no
significant effect...
Outflowing streams of matter or jets are a common phenomenon in the observeduniverse. The most extreme and powerful jets are relativistic, i.e., they travel at speedscomparable to the of speed light. Gamma Ray-Bursts (GRBs) and Active Galactic Nuclei(AGNs) are two sources of these relativistic jets. In this work I will...
We present an analysis of the relationship between spectral lag and luminosity in time-resolved segments of long gamma-ray bursts detected by BATSE, an experiment aboard the Compton Gamma Ray Observatory satellite. For full bursts, there is a well-established correlation between the lag, which is easily computed, and the total burst...
The increased severity of Clostridium difficile infection is primarily attributed to the appearance of an epidemic strain characterized as PCR ribotype 027. The only report that identified epidemic C. difficile ribotype 027 in an American country outside of North America comes from Costa Rica, raising the possibility that strains 027...
The recent multistate outbreak of
a multidrug-resistant (MDR) Salmonella Heidelberg
strain from commercial poultry production highlights
the need to better understand the reservoirs of these
zoonotic pathogens within the commercial poultry production
and processing environment. As part of a larger
study looking at temporal changes in microbial communities
within the...
OBJECTIVE: To establish a statewide network to detect, control, and prevent the spread of carbapenem-resistant Enterobacteriaceae (CRE)
in a region with a low incidence of CRE infection.
DESIGN: Implementation of the Drug Resistant Organism Prevention and Coordinated Regional Epidemiology (DROP-CRE) Network.
SETTING AND PARTICIPANTS: Oregon infection prevention and microbiology laboratory...
A major goal of the Partnership for Interdisciplinary Studies of Coastal Oceans (PISCO) has been to understand the impacts of climate change and variability on the coastal ecosystems of the inner shelf of the California Current Large Marine System in particular, and other marine and even nonmarine systems more generally....
