There is consensus among researchers that some form of hemispheric lateralization exists when perceiving emotions. However, conclusions regarding the exact organization have been inconsistent with some studies supporting an overall right hemisphere lateralization and others suggesting differential lateralization for positively and negatively valenced emotions. The main objective of this study...
There are currently three main models used to describe the pattern of hemispheric specialization (i.e., lateralization) for emotion perception: the right hemisphere hypothesis, the valence model, and the motivational model. Although evidence exists in support of all three, the variation between each pattern of results may be due to differences...
The present study was undertaken to evaluate the seasonal
botanical composition of two grass pastures, tall fescue (Festuca
arundinacea Schreb.) and perennial ryegrass (Lolium perenne L.).
Botanical composition was determined by four methods: dry-weight-rank,
weight-estimate, hand separation, and the constituent differential,
with cattle and sheep grazing at two intensities.
The...
This study examined features of deep pool (>0.8 m mean depth) used by
adult summer steelhead in Steamboat Creek (1991-1992). Steamboat Creek had
a heterogenous thermal profile, with some segments exceeding preferred
temperature of steelhead. Deep pools were scarce (4% of the total habitat units)
and 39% of them were...
After the 1996 national welfare reform known as the Personal Responsibility and Work Opportunity Reconciliation Act (PRWORA) was enacted with more stringent eligibility and work requirements for the Temporary Assistance for Needy Families (TANF) and the Supplemental Nutrition Assistance Program (SNAP) program, a plethora of analyses have followed assessing the...
The milk fat globule membrane, a major component in buttermilk, contains many complex lipids known to be involved in a variety of biological processes. Phospholipids, including sphingolipids, exhibit antioxidative, anticarcinogenic, and antiatherogenic properties and have essential roles in numerous cell functions. Filtration coupled with supercritical fluid extraction (SFE) may provide...
BACKGROUND: The giant lizard of La Gomera (Gallotia bravoana), is an endemic lacertid of this Canary Island that
lives confined to a very restricted area of occupancy in a steep cliff, and is catalogued as Critically Endangered by
IUCN. We present the first population genetic analysis of the wild population...

Individual Transferable Quota (ITQ) systems have been used to control harvests and increase fisheries’ economic efficiency; however, they do not eliminate competitive fishing which can result in stock and congestion externalities that are especially apparent when resources are spatially heterogeneous within the controlled region of the ITQ system. These externalities...
If the spatial and temporal distribution of resources is not homogenous it creates an assignment problem. While the adoption of individual (or transferable) quota management in many commercial fisheries has resolved issues of over-appropriation, assignment problems may remain due to the spatial and temporal complexity of fisheries resources, which creates...
Annual socio-economic surveys, pared with third-party landing monitoring data, have allowed a multi-year analysis of the economic impacts and perceptions of implementing an individual vessel quota rights-based management system in the gulf corvina (Cynoscion othonopterus) fishery. This fishery is targeted by four communities, including an indigenous one, in the Upper...
Previous studies have reported that the metastable vaterite phase of calcium carbonate can be stabilized in solution by acidic additives. Here we demonstrate that vaterite can also be stabilized directly at surfaces by engineered peptides. Our data show that the mineralisation occurs in a 'self-templating' process where calcium ions restructure...

Infestations of container nursery beds by Phytophthora spp. can be persistent and costly. One method of disinfestation that does not require the use of chemicals is soil solarization, which captures energy from the sun to heat soil and thermally inactivate target pathogens. In laboratory temperature gradient experiments, I investigated the...
In horticultural nurseries for container-grown plants, production and sales have been threatened by the presence of a quarantined plant pathogen, Phytophthora ramorum (causal agent of sudden oak death). Infested nursery beds are an important source of P. ramorum, which can initiate disease through movement with surface water to infect roots...
