There are many different organizations and agencies which share responsibility for educating the public about responsible use of aquatic and marine resources. However, organizations specifically focused on particular dimensions of water use, such as Oregon State Marine Board (OSMB), often face challenges when attempting to recruit teachers to implement educational...
The intent of this report is to provide a brief description of water quality issues in Nicaragua, Uganda and Bangladesh, and the technologies available to address these issues. The water quality parameters considered include: bacterial contamination, heavy metals and arsenic, pesticides and industrious chemicals, turbidity, radiological characteristics, and taste and...
This is PMEL Contribution 4396.
Acidification has sparked discussion about whether regulatory agencies should place coastal waters on the Clean Water Act 303(d) impaired water bodies list. Here we describe scientific challenges in assessing impairment with existing data, exploring use of both pH and biological criteria. Application of pH criteria...
Drought and mandatory water restrictions are limiting the availability of irrigation water in many important blueberry growing regions and new strategies are needed to maintain yield and fruit quality with less water. Three potential options for reducing water use, including deficit irrigation, irrigation cut-offs, and crop thinning, were evaluated for...
Childhood obesity and physical inactivity are significant health problems. According to the CDC (2012), only 12.5% of high school students meet the recommended requirements for physical activity. One method to reverse this trend is promoting physical activity. The Walk to School Program promotes active transportation in schools nationwide. PURPOSE: The...

Graphics hardware in mobile devices has become more powerful, allowing rendering techniques such as ray-cast volume rendering to be done at interactive rates. This increase of performance provides desktop capabilities combined with the portability of a tablet. Volumes can demand a high amount of memory in order to be loaded...
The purpose of this thesis is to better understand how students who experience anxiety that interferes with their daily functioning perceive and interact with their formal learning environments such as classrooms and lab spaces so that instruction in these spaces may be improved. Specific attention was paid to the ways...
While individual portfolio diversity analysis is a well-studied problem in visualization, the visual analysis of individual or groups of portfolios, over time, has received little attention. Such analysis, however, is important to researchers who are interested in better understanding portfolio management behavior of experts as well as novices. We conducted...
Previous studies of coral viruses have employed either microscopy or metagenomics, but few have attempted to comprehensively link the presence of a virus-like particle (VLP) to a genomic sequence. We conducted transmission electron microscopy imaging and virome analysis in tandem to characterize the most conspicuous viral types found within the...
Current research on the topic of advanced reactor fuel types include the use of ultrahigh density Uranium-Molybdenum fuels, towards their use in high-performance research reactors. These reactors operate with high power densities, and the increased cooling requirements therefore place high relevance on the fluid-structure interaction with these fuel elements; therefore...
In 2010 the American taxpayers spent $697 million educating veterans under the provisions of the Servicemen's Readjustment Act of 1944 (commonly referred to as the GI Bill). Most veterans begin their college education at a community college. However, the number of veterans succeeding in community colleges is exceedingly low. Based...
College Algebra is a prerequisite for calculus and is thus an important stepping stone in the careers of STEM-intending undergraduates. However, College Algebra has low pass rates across the United States, interrupting students’ pathways to success. To address this concern, a research-oriented university in the Northwest United States restructured its...
With the development of technologies in genome sequencing and variant detection, a huge number of variants are detected. To further analyze the variants, it requires an efficient tool to annotate the functional effect of variants. This project managed to develop an efficient program to annotate the functional effect of variants...
Background. The US commercial fishing industry is hazardous, as measured by mortality data. However, research on non-fatal injuries is limited. Non-fatal injuries constitute the majority of occupational injuries and can result in workers' lowered productivity and wages, lost quality of life, and disability. In the United States, a Work Process...
Understanding ecological interaction strengths is one of the main objectives of ecology. Recently, two methods for estimating interaction strengths of predator-prey interactions in nature have been proposed: a field observation approach proposed by Novak and Wootton (2008) and stable isotope analysis. The field observation method estimates feeding rates based on...
Vitamin D sufficiency supports cardiovascular health and lower cancer risk. Rates of vitamin D insufficiency vary by racial/ethnic group, in part because skin pigment limits sunlight penetration. However race/ethnicity is an unreliable marker of vitamin D deficiency, given individual differences in skin pigment, or phototype, and other characteristics. Clarifying associations...
Mantel-based tests have been the primary analytical methods for understanding how landscape features influence observed spatial genetic structure. Simulation studies examining Mantel-based approaches have highlighted major challenges associated with the use of such tests and fueled debate on when the Mantel test is appropriate for landscape genetics studies. We aim...
