Social vulnerability is often thought of as a culmination of social factors influencing the susceptibility of various groups to harm and govern their ability to respond. In an effort to identify communities that may be susceptible to social impacts from changes to fishery policies or fishing conditions, NOAA Fisheries is...
Bacteria found in clarified ovine rumen fluid are capable of degradation of high-energy explosives such as RDX (Hexahydro-1,3,-trinitro‐1,3,5‐triazine) and HMX (Octahydro‐1,3,5,7‐tetranitro‐1,3,5,7-tetrazocine).
Volcanic hazard maps inform the public on the nature and extent of the hazards that threaten them, but these maps are often challenging for those who are not trained in map use or geology. The maps in this study focus on lahars, a dangerous, fast, and far-reaching volcanic hazard that...
Over the past few decades, a primary focus has been on the negative health effects of not participating in regular moderate-to-vigorous physical activity (MPVA). Only recently has sedentary behavior been studied as a distinct and independent risk factor for adverse health outcomes. This dissertation sought to provide new insights into...
For each of the 5 needs in Maslow’s motivational hierarchy (physiological, safety–security, belongingness, esteem, and self-actualization), measures of satisfaction were gathered from the German Socio-Economic Panel to assess their correlations with each other in order to test the validity of the structure of Maslow’s hierarchy of needs. While other studies...
Circadian rhythms are the daily oscillations in multiple organism functions, from clock gene expression to behavior. Lost or irregular rhythms lead to health problems later in life including nervous system disorders, abnormal sleep/activity cycles, diabetes and obesity. However, it is not known whether strengthening the expression of clock genes throughout...
The 1920’s was a period of immense growth of consumer and celebrity culture, that brought changes in film, art and the creation and presentation of identity. F. Scott Fitzgerald’s Tender is the Night reflects these changes, particularly with respect to how cultural shifts challenge prevailing views about individual autonomy and...
One method for CO2 sequestration is to store the liquid form of CO2 in small cement wells in the ground. An issue with this method is the susceptibility of cement to fracture and thus release the CO2. One proposition is to fill these cracks with biofilm of the bacteria Sporosarcina...
St. Joseph's College was located within St. Paul, Oregon, the first Roman Catholic mission in the Pacific Northwest. The St. Paul mission was finally established in 1839 by Father Francois Blanchet, four years after the French-Canadian settlers in the area, appropriately known as French Prairie, had requested the presence of...

Many algorithms in parallel systems can be easily solved if we can generate a Hamiltonian cycle on the underly network. Finding Hamiltonian cycle is a well known NP-complete problem. For specific instances of regular graphs, such as Torus and Gaussian network, one can easily find Hamiltonian cycles. In this thesis,...
Releasing hatchery reared salmon and steelhead to supplement threatened and endangered populations is a widely used conservation tool. One issue with this strategy is hatchery fish have lower reproductive fitness than wild fish when spawning in the wild. One of the drivers of fitness loss in steelhead is adaptation to...
As more people become interested in rock climbing, the need to understand climbers and their preferences and how their activities impact the resource are more vital than ever. With increased use, and with little empirical data about the Yosemite climbing community, park managers cannot adequately develop a comprehensive climbing management...
Steel foundries are in great need of automation as current operations involve many hazardous manual tasks. Automating foundry operations is very challenging due to the variety of tasks that must be performed on physical objects that vary significantly in size, shape, and weight. This thesis focuses on robotically automating the...
Invasive vegetation control studies traditionally aim to control existing populations as well as limit future spread of the species. However, little additional attention has been dedicated to aiding native communities to recover and reestablish. One prominent example of a studied invasive is Brachypodium sylvaticum (Huds.) P. Beauv. (false brome), a...
Ontogenetic niche theory predicts that as organisms grow they make size-specific changes in habitat use and diet to optimize growth and survival. A variety of factors contribute to growth and survival in different habitats, ultimately leading to variation in life history that can affect population dynamics. An understanding of the...
Emerging infectious diseases impact both human and wildlife populations. Infectious agents, in particular the aquatic fungus Batrachochytrium dendrobatidis (chytrid), have an influential role in driving global amphibian population declines. The emergence of the chytrid fungus has aspects of both geographic spread as well as climate shifts altering environmental conditions and...
Although fish are a nutritious food source, they also are the main source of methylmercury exposure in U.S. populations. This research examined the risks from methylmercury and benefits from omega-3 fatty acids and selenium from fish consumption. The first study provided the first region-specific quantitative risk/benefit analysis for nine commonly...
Automating pick-and-place operations for large steel castings in a foundry is challenging, particularly from a perception point of view. Accurately estimating the identity and orientation of a given part is an open and complex problem, especially if that part sits in a bin of very similar parts. The problem is...
Fluid-structure interaction (FSI) is a very interesting and challenging multi-disciplinary field involving interaction of a movable or deformable structure with an internal or surrounding fluid flow. FSI has several practical engineering applications such as the determination of the hydrodynamic forces on a structure or the dynamics of motion of bodies...
Reintroduction programs are increasingly being used to save animals from extinction and aid in their recovery. The California Condor (Gymnogyps californianus), one of the most endangered birds in the world, is a remarkable example of how reintroduction programs can help rapidly increase a species' population numbers and range following a...
The USDA Forest Services' actions have come under greater scrutiny by a public that has become increasingly concerned with the legality of their actions. Often, challenges involve the quality of science used in the decision-making. Congress has mandated that the agency use the "best available science" in its decision making...
Several dolphin species have global distributions. The extent of their radiation and limits to gene flow are presumably a product of oceanographic features both recent and historical, behavioral specializations and social organization. Rough-toothed dolphins (Steno bredanensis) are globally distributed in tropical and subtropical waters and are generally found in depths...
Spatially explicit maps of habitat relationships have proven to be valuable tools for conservation and management applications including evaluating how and which species may be impacted by large scale climate change, ongoing fragmentation of habitat, and local land-use practices. Studies have turned to remote sensing datasets as a way to...
Over the past twenty years, the national three-year graduation rate for community college students has ranged from 44% to roughly 31% in 2013 (NCES, 2013). As a way to address such low graduation rates, colleges have implemented a myriad of services and programs (i.e., tutoring, mentoring, etc.). Another intervention is...
Creative nonfiction is a genre replete with contradictions--the name itself shows that: nonfiction writing is true and factual, but creative writing is imaginative and inventive. Because of fundamental contradictions like this, there is no standardized or even most common definition of the genre. This creates confusion for both critics and...
Recent publications show that successive approximation register (SAR) analog to digital converters (ADC) are capable of achieving high efficiency over other ADC topologies. Furthermore, techniques have been adopted to process signals with low activity periods, such as biomedical and industrial sensors. Prior work used least- significant bit first quantization (LSBFQ)...
