Studies In The Image Of The Madonna Lactans In Late Medieval And Renaissance Italy., Cecelia M. Dorger

Electronic Theses and Dissertations

This dissertation is an analysis of Italian late medieval and Renaissance peoples’ response to the Madonna lactans image. Although the images that comprise this type are similar in that Mary holds Christ at her breast, they vary widely in iconography and context. We shall use reception and response theory to determine how the image functioned for spectators. Determining how different groups responded to the motif is facilitated by applying an interpretive community model. Hence a group’s interpretive principles connect these communities and inform their reception of the image. We argue that although context and communities are diverse, most people believed …

Phenomenological Modeling Of Image Irradiance For Non-Lambertian Surfaces Under Natural Illumination., Shireen Y. Elhabian

Electronic Theses and Dissertations

Various vision tasks are usually confronted by appearance variations due to changes of illumination. For instance, in a recognition system, it has been shown that the variability in human face appearance is owed to changes to lighting conditions rather than person's identity. Theoretically, due to the arbitrariness of the lighting function, the space of all possible images of a fixed-pose object under all possible illumination conditions is infinite dimensional. Nonetheless, it has been proven that the set of images of a convex Lambertian surface under distant illumination lies near a low dimensional linear subspace. This result was also extended to …

Experience, Effectuation, And Something Good : Does The Use Of Effectuation Lead To Positive Outcomes?, Thomas E. Nelson

Electronic Theses and Dissertations

The theory of effectuation is ascending in entrepreneurship education. Hundreds of articles have been written on the topic. Many textbooks mention the theory, and one college level textbook teaches entrepreneurship entirely from an effectual perspective. Given its acceptance, the natural assumption is that effectuation is somehow 'good.' That is, there is some unique benefit that an entrepreneur gains from using effectuation. This dissertation examines the concept of effectuation, and its value to entrepreneurship. It seeks to determine if entrepreneurs who use effectual logic outperform entrepreneurs who don't. Four hundred and fifty entrepreneurs across three states are surveyed to determine if …

Department of Biochemistry: Faculty Publications

Evidence suggests that selenium has cancer preventive properties that are largely mediated through selenoproteins. Our previous observations demonstrated that targeted down-regulation of the 15 kDa selenoprotein (Sep15) in murine colon cancer cells resulted in the reversal of the cancer phenotype. The present study investigated the effect of Sep15 knockout in mice using a chemically-induced colon cancer model. Homozygous Sep15 knockout mice, and wild type littermate controls were given four weekly subcutaneous injections of azoxymethane (10 mg/kg). Sep15 knockout mice developed significantly (pGBP-1 in humans has been associated with a highly significant, increased five-year survival rate in colorectal cancer patients. In …

An Analysis Of Traffic Sign Performance For The Establishment Of A Maintenance Plan, Wesley Bill Boggs

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

For a variety of reasons both within and outside the control of transportation agencies, there is a higher frequency of fatalities during nighttime hours than during daytime hours. In an effort to enhance visual cues for nighttime motorists, the Federal Highway Administration (FHWA) established the minimum maintained retroreflectivity levels. This retroreflective mandate required agencies or public officials that have jurisdiction over a traffic sign population to implement maintenance methods that would ensure signs were performing at or above the minimum levels. Retroreflectivity is a unique type of reflection that distinguishes itself by reflecting light back in the direction of the …

Analysis Of Irrigation Decision Behavior And Forecasting Future Irrigation Decisions, Sanyogita Andriyas

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Farmers play a pivotal role in food production. To be economically successful, farmers must make many decisions during the course of a growing season about the allocation of inputs to production. For farmers in arid regions, one of these decisions on any given day is whether to irrigate. This research is the first of its kind to investigate the probable reasons that lead a farmer to make irrigation decisions and use those reasons/factors to forecast future irrigation decisions. This study can help water managers and canal operators to estimate short-term irrigation demands, thereby gaining information that might be useful to …

Performance Characterization Of Complex Fuel Port Geometries For Hybrid Rocket Fuel Grains, Andrew Bath

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Extensive research in hybrid rocket motors has taken place at the department of Mechanical and Aerospace Engineering at USU (Utah State University) in the last several years. USU has one of the few facilities in the country capable of static-test firing rocket motors on-campus, which allows for fast-paced testing and development not available elsewhere. Research has involved investigating propulsion devices for a range of applications, including micro-satellite thrusters, hot-gas generators, and even jet-assisted takeoff kick motors. Hybrid motors have the advantage of safety over any other chemical propulsion. Since the fuel and oxidizer are stored seperately, they are relatively inert …

Mechanisms And Signal Transduction Pathways Involved In Bovine Oocyte Activation, Ammon Hanson Bayles

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Being able to create a genetically identical, living replicate of a prized animal sounds impossible. Through advanced scientific methods and the wonders of mother nature it can be accomplished by a process called cloning. In 2003, the USU Animal, Dairy, and Veterinary Science department and Dr. Kenneth L. White gained world wide recognition when they, along with a team for Idaho, cloned the first equine species.

Cloning certain animals could be very advantageous to the agricultural industry. Prized animals that have died could be cloned, producing the best meat and milk supply. Animals that are sterile or endangered could be …

Modulation Of The Host Response To Tacaribe Arenavirus Infection In Ag129 Mice By My-24, Eric Sefing

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

MY-24 is a new antiviral compound recently shown to protect immunocompromised mice from lethal challenge with Tacaribe virus (TCRV). Tacaribe virus is incapable of causing disease to humans, but is closely related to the highly pathogenic New World arenaviruses that cause often-fatal viral hemorrhagic fever syndromes. Remarkably, MY-24 prevents mortality without reducing virus burden in the circulation or tissues. To investigate the mechanism by which MY-24 protects AG129 mice against Tacaribe virus infection, we first characterized the natural history of disease in the model with an emphasis on host immune response and blood vessel function to establish the best times …

The Effects Of Bison On Cattle Winter Range In The Henry Mountains Of South Central Utah: Resolving A Conflict, Ian M. Ware

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The American Bison in the Henry Mountains are one of the last free-roaming, genetically pure herds of bison remaining in North America. Over the last decade, the herd has used a cattle winter range during the summer and early fall, creating a conflict between the wildlife officials who manage the bison population, and Bureau of Land Management officials and local ranchers who manage the rangeland. At the heart of this conflict is the question of whether bison are negatively impacting the rangeland resource, potentially reducing the abundance of preferable plant species. Negative impacts could include reduced forage availability in the …

In Situ Measurements Of Electron-Beam-Induced Surface Voltage Of Highly Resistive Materials, Joshua Hodges

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Surface charging and subsequent electrostatic discharge due to interactions with the space environment is one of the primary concerns of spacecraft charging studies. Laboratory measurements of the evolution of surface voltages and dissipation currents under simulated space conditions are the primary method used to determine the response of key spacecraft materials to diverse incident fluxes. Increasing the database of information for the electronic properties of insulating materials can assist spacecraft designers in mitigating the harsh effects of the space environment.

The Utah State Materials Physics Group, with the funding of the NASA James Webb Space Telescope project and personnel support …

Closed-Loop Thrust And Pressure Profile Throttling Of A Nitrous Oxide/Hydroxyl-Terminated Polybutadiene Hybrid Rocket Motor, Zachary W. Peterson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Hybrid motors that employ non-toxic, non-explosive components with a liquid oxidizer and a solid hydrocarbon fuel grain have inherently safe operating characteristics. The inherent safety of hybrid rocket motors offers the potential to greatly reduce overall operating costs. Another key advantage of hybrid rocket motors is the potential for in-flight shutdown, restart, and throttle by controlling the pressure drop between the oxidizer tank and the injector. This research designed, developed, and ground tested a closed-loop throttle controller for a hybrid rocket motor using nitrous oxide and hydroxyl-terminated polybutadiene as propellants. The research simultaneously developed closed-loop throttle algorithms and lab scale …

This thesis describes and documents the design and construction of a light source which is tunable and has the ability to mimic the spectral output of the sun in the photosynthetic active radiation range (400 - 700 nm). To adjust the spectral output at different wavelengths different types of LEDs were chosen and combined. This thesis describes the design, construction, testing, and suggestions for further improvements to this light source. The light source is comprised of 900 LEDs with 26 different peak wavelengths within the photosynthetically active radiation range. The light source is made tunable through the use of a …

Process Variation Aware Dram (Dynamic Random Access Memory) Design Using Block-Based Adaptive Body Biasing Algorithm, Satyajit Desai

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Process variation can be defined as the deviation of process parameters from its nominal specifications. Variation is induced by several fundamental effects resulting from inaccuracies in the manufacturing equipment. It is a combination of systematic effects (e.g., lithographic lens aberrations) and random effects (e.g., dopant density fluctuations). The effect of process variation becomes particularly important at smaller process nodes, where the variation accounts for a major percentage of nominal length or width of the device. Process variations translate to a wide range in performance metrics of current designs. As technology scales, these die variations are getting larger, significantly affecting performance …

Transportation Network Resiliency: A Study Of Self-Annealing, Sunil Babu Pant

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Disasters have the potential to hit any geographical location with or without warning. As such, it is desirable that transportation networks are able to withstand the adverse effect of disasters and maintain the normal functioning of all sectors of society. Resilient transportation networks are least affected by disruptions created by natural and manmade disasters and are still able function with an acceptable level of service. Such networks also have ability to return earlier from disrupted state to the normal functioning state. Resilience possessed by a transportation network measures the ability of networks to maintain functionality despite adverse conditions posed by …

A Study Of Utah’S New Century Scholarship (Ncs) Program, Christine Kearl

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This was a study about the New Century Scholarship (NCS) program offered to Utah high school students at commencement for earning an AA degree by the time of high school graduation. The scholarship paid 75% of the remaining 2 years of tuition over a 5-year period. The goal of the program was to assist students to bachelor degree completion faster than the traditional time.

This program has been in Utah for the past 20 years, but little to no information about the program exists. Annually, the cost to taxpayers is approximately $2 million dollars. This study was conducted to determine …

Space Plug-And-Play Architecture Networking: A Self-Configuring Heterogeneous Network Architecture, Jacob Holt Christensen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In spacecraft engineering, the time and money involved in satellite construction is largely spent on design and integration of custom hardware and software. These efforts are duplicated for nearly every satellite with little to no reuse between spacecraft. There is a huge potential for cost savings in removing the duplication of work. However, there is a lack of standardization in the spaceflight community, causing soaring costs and delayed schedules as each component of a spacecraft is individually designed and custom built.

The Air Force Research Laboratory (AFRL) has developed the Space Plug-and-Play Architecture (SPA) to address this problem. SPA provides …

Process And Domain Specificity In Regions Engaged For Face Processing: An Fmri Study Of Perceptual Differentiation, Heather R. Collins, Xun Zhu, Ramesh S. Bhatt, Jonathan D. Clark, Jane E. Joseph

Psychology Faculty Publications

The degree to which face-specific brain regions are specialized for different kinds of perceptual processing is debated. This study parametrically varied demands on featural, first-order configural, or second-order configural processing of faces and houses in a perceptual matching task to determine the extent to which the process of perceptual differentiation was selective for faces regardless of processing type (domain-specific account), specialized for specific types of perceptual processing regardless of category (process-specific account), engaged in category-optimized processing (i.e., configural face processing or featural house processing), or reflected generalized perceptual differentiation (i.e., differentiation that crosses category and processing type boundaries). ROIs were …

With the increased popularity of social networking through websites like Facebook, more are taking to the Internet to engage in civic dialogue. This study will explore how the exchange of socially networked images, texts, and audio between Democrats and Republicans affect beliefs, behaviors and perceptions. Utilizing qualitative methodologies, the researcher interviewed ten (10) registered democrats and ten (10) registered republicans. The participants were basked ten questions and ten follow up questions. The study applied a social network analysis to evaluate how socially networked dialogue between Republicans …

Bankrupt Estoppel: The Case For A Uniform Doctrine Of Judicial Estoppel As Applied Against Former Bankruptcy Debtors, Eric Hilmo

Fordham Law Review

   This Note examines the role judicial estoppel plays in supporting the U.S. federal bankruptcy regime. Though once considered an obscure doctrine, the use of judicial estoppel to bar pursuit of previously undisclosed claims by former bankrupts has grown apace with burgeoning bankruptcy filings over the last decade. While the doctrine’s application in federal courts has evolved toward a common standard of application, state courts’ application remains idiosyncratic. The Note argues that under the established laws of judgment recognition and in light of federal courts’ sophisticated application of the doctrine, state courts should apply federal judicial estoppel standards to further national …

Inside Voices: Protecting The Student-Critic In Public Schools, Josie F. Brown

Faculty Publications

First Amendment doctrine acknowledges the constructive potential of citizens’ criticism of public officials and governmental policies by offering such speech vigilant protection. However, when students speak out about perceived injustice or dysfunction in their public schools, teachers and administrators too often react by squelching and even punishing student-critics. To counteract school officials’ reflexively repressive responses to student protest and petition activities, this Article explains why the faithful performance of public schools’ responsibility to prepare students for constitutional citizenship demands the adoption of a more receptive and respectful attitude toward student dissent. After documenting how both educators and courts have mistakenly …

Civil Rights, Charter Schools, And Lessons To Be Learned, Derek W. Black

Faculty Publications

Two major structural shifts have occurred in education reform in the past two decades: the decline of civil rights reforms and the rise of charter schools. Courts and policy makers have relegated traditional civil rights reforms that address segregation, poverty, disability, and language barriers to near irrelevance, while charter schools and policies supporting their creation and expansion have rapidly increased and now dominate federal policy. Advocates of traditional civil rights reforms interpret the success of charter schools as a threat to their cause, and, consequently, have fought the expansion of charter schools. This Article argues that the civil rights community …

Beyond Law Enforcement: Camreta V. Greene, Child Protection Investigations, And The Need To Reform The Fourth Amendment Special Needs Doctrine, Josh Gupta-Kagan

Faculty Publications

The Fourth Amendment “special needs” doctrine distinguishes between searches and seizures that serve the “normal need for law enforcement” and those that serve some other “special need,” excusing non-law enforcement searches and seizures from the warrant and probable cause requirements. The Supreme Court has never justified drawing this bright line exclusively around law enforcement searches and seizures but not those that threaten important non-criminal constitutional rights.

Child protection investigations illustrate the problem: Millions of times each year, state child protection authorities search families’ homes, and seize children for interviews about alleged maltreatment. Only a minority of these investigations involve an …

Transforming The Healthcare Response To Intimate Partner Violence And Taking Best Practices To Scale, Michele R. Decker, Shannon Frattaroli, Brigid Mccaw, Ann L. Coker, Elizabeth Miller, Phyllis Sharps, Wendy G. Lane, Mahua Mandal, Kelli Hirsch, Donna M. Strobino, Wendy L. Bennett, Jacquelyn Campbell, Andrea Gielen

CRVAW Faculty Journal Articles

BACKGROUND: Intimate partner violence (IPV) is prevalent among adolescent and adult women, with significant physical, sexual, and mental health consequences. In 2011, the Institute of Medicine's Clinical Preventive Services for Women consensus report recommended universal screening for violence as a component of women's preventive services; this policy has been adopted by the Health Resources and Services Administration (HRSA). These policy developments require that effective clinic-based interventions be identified, easily implemented, and taken to scale.

METHODS: To foster dialogue about implementing effective interventions, we convened a symposium entitled "Responding to Violence Against Women: Emerging Evidence, Implementation Science, and Innovative Interventions," on …
