The bi-directional relationships within the personal and contextual environments of adolescents are critical to the development of adolescents and their transition into adulthood. Opportunities for youth to participate in and provide leadership in meaningful programs, gain life skills, and interact with adults in sustained relationships are key features leading to...
The primary purpose of this study was to determine which factors related to adult 4-H volunteer empowerment in 4-H youth development settings. This study examined the relationship of adult 4-H volunteers’ perceived leadership styles of Oregon 4-H Youth Development Educators (YDE) to the adult 4-H volunteer sense of empowerment. In...
Despite several factors favoring the development of haddock (Melanogrammus aeglefinus) aquaculture, there is virtually no economic information on its feasibility. This paper uses bioeconomic simulation techniques to conduct an ex-ante impact assessment of the early life stages in haddock production. Using an economic engineering methodology, early life stages are modeled...
A NE–SW-trending graben at Kap Dalton on the Blosseville Kyst contains an at least 600 m thick
succession of Eocene basalt lavas and sediments. The succession has been investigated by new field
work, geochemical analysis and radiometric dating by the ⁴⁰Ar-³⁹Ar incremental heating method.
The results show that the volcanic...
A study was conducted to determine effects of year and season on diet quality of beef cattle grazing northern Great Basin rangelands from 1990 to 1993. Forage quality was high early in the growing season, then declined as seasons progressed (P<.05). Plant chemical composition was higher early in the growing...
PART I. The concentration of nickel in some soils may be
insufficient to meet the requirements of enzymes such as
urease in soybeans and hydrogenase in Rhizobium. Nickel
availability in soils was examined by measuring microbial
urease activity in soils which were treated with glucose
and urea. Supplemental nickel was...
from the summer dry season to the winter wet season. Such movement that connects summer and winter habitats may be particularly important for coho salmon, O. kisutch, because availability of overwintering habitat can limit freshwater survival for this species. Here, I describe basin-scale variability in the spatial pattern of fall...
