Using Computational Fluid Dynamics For Predicting Hydraulic Performance Of Arced Labyrinth Weirs, Shelby J. Koldewyn

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Our world is dynamic and as hydrologic research continues, the magnitude of flood estimates used in hydraulic design for reservoirs has increased. Consequently, many existing spillways are now undersized and unable to meet discharge requirements. These spillways often have a fixed footprint, so nonlinear weirs (e.g., labyrinth weirs) are often a viable solution. For reservoir applications, arcing labyrinth weirs in plan view increases hydraulic efficiency because of better cycle orientation to the approaching flow from the reservoir. This study supplements available physical arced labyrinth weir hydraulic data by observing flow characteristics of two numerical models (α=16°; θ=10° …

Big Fish And More Of Them: Salmonid Habitat Availability, Quality, And Use Across Multiple Scales Within A River-Reservoir System, John S. Mclaren V

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Reservoirs and their associated rivers provide water for agricultural and municipal uses, ecological benefits for fish and wildlife, and associated recreational activity. However, in the Greater Yellowstone Ecosystem climate change and population growth are putting pressure on water quality and supply, potentially damaging the unique and economically important coldwater trout habitat that these systems support. In this study, the author investigates the impact of changing water quality and supply on trout habitat quality, quantity, and selection to assist conservation goals in the Henry’s Fork Watershed in eastern Idaho. The study found that higher availability of cold-water refuge habitat in Island …

“Whan The Turuf Is Thy Tour”: Analyzing Gender Codes Of Burial Monuments In Late Medieval And Early Modern England, Shelbie Durrant

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The cultural pressures of gender conformity and "norms" have lasted as long as the social constructs of gender themselves. Gender is present and can be analyzed in symbols within material culture such as the Russell family funerary monuments located in their private chapel in Chenies, London. Gender, although not always transparently at the front of consciousness, was interacted with, performed, and memorialized in life and death, especially for families that were high status. The presence of gender in these funerary monuments illuminates how expected conformity of gender norms were in this time — so present that they were literally set …

Navigating Cultural Identity In The Classroom, Caroline V. Phillips

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

As of 2016, ~25% of children in the United States are the children of immigrants (Nibbs & Brettell). Many of these youths struggle with the feeling that they belong neither to their parents’ cultural community nor to the locality in which they have been raised (Brockett, 2018). Furthermore, little academic research exists wherein these students share their experiences and engage in the processes of meaning making. This knowledge is essential for multicultural scholars and also for the (overwhelmingly white) population of K-6 teachers who help these youth construct personal identities. This project accomplishes the following:

1. I interview second-generation immigrants …

"God Put It Into My Heart": Omen-Seeking And Divine Communication Narratives In Contemporary American Protestantism, Emma Crisp

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

This project examines omen-seeking practices within Protestant Christianity in the U.S. Intermountain West. It collates and analyzes the results of ethnographic research into the ways that mainline Protestants experience, interpret, and talk about their personal spiritual experiences. The project finds that divinatory and other omen-seeking practices exist in this context but are not recognized or discussed as divinatory due to the conflation of divination with sortilege and the prevalence of prayer as the primary solicitation method for Protestant forms of augury. Emic categories of omen are distinguished not through generation method (such as the solicited/unsolicited distinction proposed by Tom Mould), …

While data revealed similar trends among Black, Hispanic or Latino/a/x/e, Native, Indigenous, and Asian people, outcomes are compounded for people of color with I/DD. Several historical, pervasive, systemic, structural, and attitudinal barriers have constrained healthcare access and adequate treatment, instigating feelings of distrust among those in systems of care. Although …

Reimagining Disability: A Call To Action, Paritosh Joshi, Julia Pappageorge

Developmental Disabilities Network Journal

This article focuses on how the medical profession, organizations, and universities should incorporate the social model of disability into their regulations and policies to advance justice for individuals with disabilities. Traditionally, disability has been viewed through the medical model, which postulates that one’s individual body or mind is medically impaired and diminishes the person’s quality of life. The model overemphasizes individual difference or disability diagnosis as something that should be treated at an individual level through medical intervention, and ignores social factors that impact the development of physical and mental conditions. Moreover, this pervasive attitude towards disability permeates institutions and …

The Effects Of Joint Training On Career And Technical Education And Special Education Professionals, Crystal K. Emery, Robert L. Morgan

Developmental Disabilities Network Journal

Abstract

Young adults with intellectual and/or developmental disabilities who leave high school have limited options in adulthood. Their rates of competitive employment in inclusive community settings is very low compared to their counterparts without disabilities. Involvement in postsecondary education and independent, community living is likewise limited. They need teams of trained professionals representing relevant disciplines who work together to support the student along college, career, and community pathways. Not only should special educators (SPED) be trained, but career technical education (CTE) professionals should be jointly trained in how to collaborate effectively and provide well-coordinated services. The purpose of this research …

Office of Research Faculty and Staff Publications

Chikungunya virus (CHIKV) is a mosquito-transmitted pathogen that causes chikungunya disease (CHIK); the disease is characterized by fever, muscle ache, rash, and arthralgia. This arthralgia can be debilitating and long-lasting, seriously impacting quality of life for years. Currently, there is no specific therapy available for CHIKV infection. We have developed a despeciated equine polyclonal antibody (CHIKV-EIG) treatment against CHIKV and evaluated its protective efficacy in mouse models of CHIKV infection. In immunocompromised (IFNAR^−/−) mice infected with CHIKV, daily treatment for five consecutive days with CHIKV-EIG administered at 100 mg/kg starting on the day of infection prevented mortality, reduced …

Assessing Downstream Aquatic Habitat Availability Relative To Headwater Reservoir Management In The Henrys Fork Snake River, Christina N. Morrisett, Robert W. Van Kirk, Sarah E. Null

Watershed Sciences Student Research

Reservoirs are sometimes managed to meet agricultural and other water demands, while also maintaining streamflow for aquatic species and ecosystems. In the Henrys Fork Snake River, Idaho (USA), irrigation-season management of a headwater reservoir is informed by a flow target in a management reach ~95 km downstream. The target is in place to meet irrigation demand and maintain aquatic habitat within the 11.4 km management reach and has undergone four flow target assignments from 1978 to 2021. Recent changes to irrigation-season management to maximize reservoir carryover warranted investigation into the flow target assignment. Thus, we created a streamflow-habitat model using …
