The issue of global climate change and possible remedies has been debated between national governments since the 1970s. While some countries have adopted aggressive measures to address the issue, others have lagged in their efforts. The United States, as a key player in global climate change conferences, has focused its...
New policies require legitimacy to survive. Prison privatization represents a policy challenged by initial perceptions of illegitimacy. In the 1980s, governments began to allow private firms to run correctional facilities, thereby shifting an inherently coercive, traditionally governmental function—incarceration—to the private sector. With data from 706 articles in four major American...
Library faculty are often tenure track, requiring a record of significant publishing and service before achieving tenure. However, meaningful tools and methods for evaluating the scholarship of librarianship frequently fall short of providing an accurate picture of the scholarship of any particular candidate. The authors conducted a case study analyzing...

This dissertation examines the impact of the German naturalist and literary figure Johann Wolfgang von Goethe’s ideas on twentieth century Anglophone plant morphology and biology. Goethe interpreted the organ forms of flowering plants as metamorphoses of each other. His literary, historical, and philosophical writings suggest themes of alienation from and...
Large ensembles of regional climate simulations were generated from the weather@home distributed volunteer computing project over the western US domain. Weather@home uses the U.K. Met Office Hadley Centre’s regional climate model HadRM3P (~0.22°) nested within the atmospheric global model HadAM3P (1.875 longitude° by 1.25 latitude°). Simulations from HadRM3P were evaluated...
Cyanobacterial harmful algae blooms (cyanoHABs) are a growing concern worldwide due to damage of ecosystems and threats to human health. Previous research indicates that plant humics from aquatic and wetland vascular plants are effective inhibitors of cyanobacterial metabolism and growth and may be useful as control agents for mitigating cyanoHABs....
Climate change, population growth, aging infrastructure, poor water management, and aquifer depletion are reducing US water supply. Increasing water scarcity will lead to an inability to support agriculture, industry, energy, and municipal demand that will negatively affect US economic growth and national security.

In this work we will analyze branching Brownian motion on a finite interval with oneabsorbing and one reflecting boundary, having constant drift rate toward the absorbingboundary. Similar processes have been considered by Kesten ([12]), and more recently byHarris, Hesse, and Kyprianou ([11]). The current offering is motivated largely by 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,...
In marine ecosystems, rising atmospheric CO2 and climate change are associated with concurrent shifts in temperature, circulation, stratification, nutrient input, oxygen content, and ocean acidification, with potentially wideranging biological effects. Population-level shifts are occurring because of physiological intolerance to new environments, altered dispersal patterns, and changes in species interactions. Together...
Seasonal wetlands in arid and semi-arid lands provide an important source of surface water in otherwise dry lands. Central Oregon's high desert, located in the Northern Great Basin (NGB) is dotted with hundreds of seasonal pools, locally called playas. The playas hold water or snow during parts of winter and...
