Process-based hydrological models have a long history dating back to the 1960s. Criticized by some as over-parameterized, overly complex, and difficult to use, a more nuanced view is that these tools are necessary in many situations and, in a certain class of problems, they are the most appropriate type of hydrological model. This is especially the case in situations where knowledge of flow paths or distributed state variables and/or preservation of physical constraints is important. Examples of this include: spatiotemporal variability of soil moisture, groundwater flow and runoff generation, sediment and contaminant transport, or when feedbacks among various Earth’s system …

Experience With Dynamic Reinforcement Rates Decreases Resistance To Extinction, Andrew R. Craig, Timothy A. Shahan

Psychology Faculty Publications

The ability of organisms to detect reinforcer-rate changes in choice preparations is positively related to two factors: the magnitude of the change in rate and the frequency with which rates change. Gallistel (2012) suggested similar rate-detection processes are responsible for decreases in responding during operant extinction. Although effects of magnitude of change in reinforcer rate on resistance to extinction are well known (e.g., the partial-reinforcement-extinction effect), effects of frequency of changes in rate prior to extinction are unknown. Thus, the present experiments examined whether frequency of changes in baseline reinforcer rates impacts resistance to extinction. Pigeons pecked keys for variable-interval …

Concentration And Ratio Of Essential Fatty Acids Influences The Inflammatory Response In Lipopolysaccharide Challenged Mice, Korry J. Hintze, J. Tawzer, Robert E. Ward

Nutrition, Dietetics, and Food Sciences Faculty Publications

The goal of this study was to evaluate the role of both the % of dietary, 18-carbon PUFA (2.5%, 5% and 10%) and the n-6:n-3 ratio (1:1, 10:1 and 20:1) on the acute inflammatory response. Mice were fed diets for 8 weeks and injected intraperitoneally with LPS to induce acute inflammation. After 24. h mice were sacrificed and plasma cytokines measured. Diets significantly affected the erythrocyte PUFA composition and the effect of PUFA ratio was more prominent than of PUFA concentration. The % dietary PUFA affected feed efficiency (p

Promoting Immigrant Parents’ Engagement In Early Intervention Through Culturally And Linguistically Responsive Service Delivery, Wendy B. Wieber, Lucia Quinonez Sumner

Journal of Early Hearing Detection and Intervention

This article focuses on the use of culture-based play, songs, and games in the early education of newcomers to the United States. Current studies examine culturally inclusive practices in PreK-12 schools in America, Canada, and Australia and suggest that parents participate more enthusiastically when their cultural orientation is honored. Although there is scant research regarding in-home early intervention for infants and toddlers who are deaf or hard of hearing for recent immigrants to the United States, the same principle may hold true for this group of immigrants. The type of parent involvement that an early interventionist in the U.S. hopes …

Professional Competence To Promote Resilience For Children Living In Poverty, Jenna M. Voss, Susan Lenihan

Journal of Early Hearing Detection and Intervention

Poverty has a tremendous impact on the educational results of all children, including those who are deaf or hard of hearing. With targeted, evidence-based interventions during the first three years of life, Early Hearing Detection and Intervention (EHDI) professionals can protect children from the numerous risk factors which impede development. While EHDI professionals often serve children and families living in poverty, it remains the case that the professional preparation programs offer limited instruction and experience in how to best serve children and families living in poverty. The purpose of this study was to explore professional preparedness to serve children who …

Coding By Choice: A Transitional Analysis Of Social Participation Patterns And Programming Contributions In The Online Scratch Community, Deborah A. Fields, Yasmin B. Kafai, Michael T. Giang

Instructional Technology and Learning Sciences Faculty Publications

While massive online communities have drawn the attention of researchers and educators on their potential to support active collaborative work, knowledge sharing, and user-generated content, few studies examine participation in these communities at scale. The little research that does exist attends almost solely to adults rather than communities to support youths’ learning and identity development. In this chapter, we tackle two challenges related to understanding social practices that support learning in massive social networking forums where users engage in design. We examined a youth programmer community, called Scratch.mit.edu, that garners the voluntary participation of millions of young people worldwide. We …

Ungulate Reproductive Parameters Track Satellite Observations Of Plant Phenology Across Latitude And Climatological Regimes, David C. Stoner, Joseph O. Sexton, Jyoteshwar Nagol, Heather H. Bernales, Thomas C. Edwards Jr.

Wildland Resources Faculty Publications

The effect of climatically-driven plant phenology on mammalian reproduction is one key to predicting species-specific demographic responses to climate change. Large ungulates face their greatest energetic demands from the later stages of pregnancy through weaning, and so in seasonal environments parturition dates should match periods of high primary productivity. Interannual variation in weather influences the quality and timing of forage availability, which can influence neonatal survival. Here, we evaluated macro-scale patterns in reproductive performance of a widely distributed ungulate (mule deer, Odocoileus hemionus) across contrasting climatological regimes using satellite-derived indices of primary productivity and plant phenology over eight degrees of …

A Social Semiotic Analysis Of Instructional Images Across Academic Disciplines, Amy Wilson-Lopez, Melanie Landon-Hays

Teacher Education and Leadership Faculty Publications

Framed in theories of social semiotics, this descriptive multiple case study examined the images used by six middle-school teachers during one school year as they each taught two different subject areas: earth science, language arts, mathematics, and/or social studies. Using Kress and Van Leeuwen’s visual grammar to analyze these images, this study identified discipline-specific patterns in how 1,132 images realized assumptions in regards to the ideational and interpersonal metafunctions of communication. A content analysis suggested discipline-specific differences in the presumed social distance between the content of the images and the students, as well as discipline-specific differences in assumptions about the …

The effect of surface or lattice modification of nanoparticles (NPs) on terrestrial plants is poorly understood. We investigated the impact of different zinc oxide (ZnO) NPs on green pea (Pisum sativum L.), one of the highest consumed legumes globally. Pea plants were grown for 65 d in soil amended with commercially available bare ZnO NPs (10 nm), 2 wt% alumina doped (Al2O3@ZnO NPs, 15 nm), or 1 wt% aminopropyltriethoxysilane coated NPs (KH550@ZnO NP, 20 nm) at 250 and 1000 mg NP/kg soil inside a greenhouse. Bulk (ZnO) and ionic Zn (zinc chloride) were included as controls. Plant fresh and dry …

Development Of Elisa Assay For D1327 Adenovirus, Christopher Peterson, Yohichi Kumaki, Dale L. Barnard

Biology Posters

Adenoviruses are a common cause of upper respiratory tract infections in children and the source of acute respiratory disease outbreaks among military recruits. Named after the human adenoid tissue it was first isolated in, the adenoviridae are non-enveloped, double-stranded DNA viruses with over 50 serotypes1. Yet to date vaccines have been developed for only two serotypes, and no adenovirus antiviral drugs have been approved by the FDA, highlighting the need for more research. In virus research, detection the presence of a particular virus is of especial interest when developing animal or cell models. As human pathogens often do not infect …

Analysis Of Rocky Mountain Snail (Oreohelix Sp.) Dietary Preference, Michael R. Bernard, Joseph S. Wilson

Biology Posters

Rocky Mountain snails in the genus Oreohelix go mostly unnoticed beneath layers of leaf litter in the western Mountain ranges. These snails are most common in rocky foothill habitat that consists of high-density deciduous groves of maple and oak. It is in this habitat where a great number of unobserved feeding behaviors occur. While some research indicates that terrestrial snails may prefer to feed on living plants, it is thought that Oreohelix are detritivores, feeding primarily on decomposing plant matter. In this study we investigated Oreohelix diet by designing a food preference experiment. We provided two food sources (Boxelder maple …

Use Of A Mouse Model To Evaluate The Effect Of Statins On The Immune Response To An Influenza Virus Vaccine, Calvin Olsen, Bart Tarbet

Biology Posters

Statins are cholesterol lowering drugs that have shown a profound effect on human health by reducing cardiovascular disease. However, two recent publications in the Journal of Infectious Diseases showed that statin use had a negative impact on the influenza vaccine response in elderly individuals [1, 2]. We propose to evaluate the immune response following vaccination in mice undergoing statin treatment. An initial study will determine the therapeutic window for statin treatment of mice fed a lipid-enriched diet. From the literature this window is expected to be between 21-28 days. That therapeutic window will be used for evaluation of the immune …
