Because of the intangible nature of online shopping, consumers perceive online shopping as being risky. This study examined how this risk can be reduced specifically by using a more effective online product presentation method. A combination of the number of product views (one and four) and size (small and large)...
Family forest owners (FFOs) control a majority of private forestland in the United States and have widely diverse ownership and management objectives. Many FFOs manage their holdings for timber production and, thus, are concerned with issues such as reforestation incentives and tax treatment of timber revenues. Their actual knowledge of...
Vibrio cholerae, an etiological agent of cholera, circulates between aquatic reservoirs and the human gastrointestinal tract. The
type II secretion (T2S) system plays a pivotal role in both stages of the lifestyle by exporting multiple proteins, including cholera
toxin. Here, we studied the kinetics of expression of genes encoding the...
We propose a mathematical formulation for strategic relay network design and dispatching method selection for full truckload transportation. The proposed model minimizes total transportation and installation costs of a mixed fleet dispatching system combining relay network and point-to-point dispatching. Operational constraints such as maximum driver tour length and load circuity...
We investigated habitat attributes related to the occupancy of the globally rare and endangered
epiphytic lichen, Erioderma pedicellatum, in a newly discovered (2009) population center in Denali National
Park and Preserve (DNPP), Alaska. We measured forest, tree and epiphytic lichen community
characteristics on eighty-five systematically selected plots in four study...
A key challenge for resource and land managers is predicting the consequences of climate warming on streamflow and water
resources. During the last century in the western United States, significant reductions in snowpack and earlier snowmelt have led
to an increase in the fraction of annual streamflow during winter and...
Floods are the most frequent natural disaster, causing more loss of life and property than any other in the USA. Floods also strongly influence the structure and function of watersheds, stream channels, and aquatic ecosystems. The Pacific Northwest is particularly vulnerable to climatically driven changes in flood frequency and magnitude,...
Paleomagnetic analysis and radiocarbon dating of an expanded Holocene deep-sea sediment sequence
recovered by Integrated Ocean Drilling Program (IODP) Expedition 303 from Labrador Sea Site U1305
(Lat.: 57°28.5 N, Long.: 48°31.8 W, water depth 3459 m) provides insights into mechanisms that drive
both paleomagnetic secular variation (PSV) and magnetization acquisition...
The epiphytic lichen Letharia vulpina has been commonly sampled in-situ for nitrogen (N) deposition biomonitoring studies but has never before been transplanted for this purpose. In the high-elevation wilderness areas of southern California Letharia vulpina is generally uncommon, making in-situ sampling difficult. In this study, we compared thallus N accumulation...
