Adolescent substance use is a developmentally contingent social practice that is constituted within the routine social-environment of adolescents' lives. Few studies have examined peer networks, perceived activity space risk (risk of substance use at routine locations), and substance use. We examined the moderating influence of peer network characteristics on the...
Saccharomyces cerevisiae contains three NAD⁺/NADH kinases, one of which is localized in
mitochondria and phosphorylates NADH in preference to NAD⁺. Strand et al (Euk. Cell
2:809 (2003)) reported that a yeast mutation in POS5, which encodes the mitochondrial
NADH kinase, is a mutator, specific for mitochondrial genes. Because of the...

As the elderly population increases, more family, friends, and paid service providers assist them with consumption activities in a group that the authors conceptualize as the elderly consumption ensemble (ECE). Interviews with members of eight ECEs demonstrate consumption in advanced age as a group phenomenon rather than an individual one,...
Applying concepts from the behavioral complexity literature (Ashby, 1952; Denison, Hooijberg, and Quinn, 1995) we examine if supply managers’ multiple roles and the ability to shift among these roles is related to their interpersonal relationship with their key contact within the strategic suppliers’ organization and ultimately with the firm-to-firm relationship....
Viruses were defined as one of the two principal types of organisms
in the biosphere, namely, as capsid-encoding organisms in
contrast to ribosome-encoding organisms, i.e., all cellular life
forms. Structurally similar, apparently homologous capsids are
present in a huge variety of icosahedral viruses that infect bacteria,
archaea, and eukaryotes. These...
We compared brood sizes among adult female Euphausia pacifica Hansen, 1911 from 3
populations in the North Pacific: Puget Sound, Washington, USA; Toyama Bay, Japan; and the Oregon coast, USA. Additionally, we used multiple linear regression models to compare the interspecific brood size as a function of female length and...
Ambient ultraviolet-B radiation can harm amphibian eggs, larvae and adults. However, some amphibians avoid UV-B radiation when given the opportunity. The strawberry poison dart frog, Oophaga pumilio, is diurnal and males vocalize throughout the day in light gaps under forest canopies that expose them to solar radiation. Previous studies have...
Time-depe ndencies of suspended-sediment discharge from six coastal watersheds of northern Califor nia
– Smith River, Klamath River, Trinity River, Redwood Creek, Mad River, and Eel River –were evaluated
using monitoring data from 1955 to 2010. Suspended-sediment concentrations revealed ti me-dependent
hysteresis and multi-year trends. The multi-year trends had two...
