The success of civil engineering construction in cold regions often depends on the
assessment of the potential for frost heave. Over the past two decades two models have
been presented to the engineering community to identify the frost heave potential,
namely: (1) the segregation potential (SP), and (2) the discrete...
The carbon is photoelectron spectrum of CO₂ has been measured with very high photon energy resolution. The natural lifetime of the carbon is hole state has been determined from a series of spectra taken at photon energies of 308, 320, and 330 eV. The measured values of the lifetimes show...
The undermining of bridge foundations can lead to either costly repairs or a bridge
collapse. These foundations must be designed to counter the effects of scour. Current
practice does not allow for accurate estimates of scour in erodible rock. Scour in rock can be related to geotechnical and hydraulic properties....
Contingent valuation has been used to elicit values
for changes in the quantity and quality of nonmarket
amenities. Yet hypothetically trading dollars for
environmental improvements is not a familiar activity for
most survey respondents. A variety of response effects
associated with survey collected data can potentially lead
to biased contingent...
Since harvest levels of many of the world's fisheries are not likely to increase in
the foreseeable future, resource managers and seafood processors need to develop
improved strategies to maximize the utilization and benefits of current catches. In
addition to increasing utilization and benefits, seafood processors are subject to the...
The goal of this study is to test the accuracy of
various mutual fund timing and selectivity models under a
range of portfolio managerial skills and varying market
conditions. Portfolio returns in a variety of skill
environments are generated using a simulation procedure. The
generated portfolio returns are based on...
Despite the fact that fishing is an inherently uncertain business, risk has rarely
been formally recognized in fisheries science or management. Few fishery
management plans include any form of risk assessment and those that do focus on
minimizing risk caused by uncertainty associated with markets and environmental
conditions. Fishermen's attitudes...
Consumers' risk perceptions are examined to explain the underlying reasons for consumer
concern associated with milk from dairy herds treated with recombinant bovine growth
hormone (rbGH). A focus group study was employed as an initial step in exploring the
primary influences of consumer apprehension toward rbGH's use. The information
obtained...
