How do you test a program when only a single user, with no expertise in software testing, is able to determine if the
program is performing correctly? Such programs are common today in the form of machine-learned classifiers. We consider the
problem of testing this common kind of machine-generated program...

The model presented herein is the same as that of Leon et al. (2010b), except that it has been
modified to preserve "lake at rest" conditions in sloped prismatic conduits. The results of the
new model (present paper) are identical to those of Leon et al. (2010b) for non-rest conditions....
Weed management practices were evaluated in a new field of trailing blackberry (Rubus L. subgenus Rubus Watson) established in western Oregon. The field was planted in May 2010 and certified organic in May 2012. Treatments included two cultivars, Marion and Black Diamond, grown in 1) non-weeded plots, where weeds were...
This article examines visitor perceptions of voluntary environmental programs (VEPs) at the Mt. Bachelor ski area in Oregon, USA by examining what they know about VEPs, how these programs influence motivations to visit this area currently and in the future, and how place attachment, value orientations, and specialization influence these...
We have developed VitisCyc, a grapevine-specific metabolic pathway database that allows
researchers to (i) search and browse the database for its various components such as
metabolic pathways, reactions, compounds, genes and proteins, (ii) compare grapevine
metabolic networks with other publicly available plant metabolic networks, and (iii)
upload, visualize and analyze...
Lidar is currently the most accurate method for remote estimation of forest structure, but it has limited spatial and temporal coverage. Conversely, Landsat data are more widely available, but exhibit a weaker relationship with structure under medium to high leaf area conditions. One potentially valuable means of enhancing the relationship...
