The United States Congress set out to increase the blending of biofuels by updating and implementing the Renewable Fuel Standard (RFS2) in 2007. The new mandate required that a combination of 36 billion gallons of ethanol, biodiesel, and cellulosic biofuel be blended annually, by 2022. To offset the cost of...
Economists have devoted considerable attention to rent-dissipation in limited-entry fisheries as a result of excessive use of capital inputs, or "capital stuffing." We may refer to this mechanism of rent dissipation as "cost-driven rent dissipation." An alternative potential mechanism of rent dissipation, which we refer to as "value-driven rent dissipation,"...
The role of fire as a natural disturbance, its interactions with nonnative species and effects of repeated fires in the Hawaiian Islands have received little investigation. We are unsure of the role fire played in shaping forest structure and composition as well as affecting evolutionary processes of the native biota....
Historically fire has been the primary disturbance factor in the sagebrush-steppe. The settlement of the West by Euro-Americans, grazing by domestic livestock, and the concomitant spread of invasive species have altered the historical fire regime. Understanding the long-term vegetation structure and fuel succession of the various sagebrush-dominated communities of this...
This study examined the effect that three environmental
hues had on subjects' work performance and on mood levels of
anxiety, depression, and arousal in an office work environment.
Pre-test post- test measurements of differences in work performance
and mood levels were used to test twelve hypotheses. Work
performance was measured...

The purpose of this study was to develop an achievement test
suitable for eighth grade industrial arts, in the Province of British
Columbia. The test was designed to conform to the limitations established
in the curriculum bulletin, Industrial Arts 8, authorized in
1962. Norms were to be developed from the...
The problem was to determine (1) to what extent the Industrial
Arts Program had expanded in facilities, enrollment and teachers
from 1952 to 1962, (2) to compare the status of the Industrial Arts
Program in 1952 with that in 1962 to determine growth and trends,
and (3) to determine to...
