A Study Of Habitat Variables Associated With Northern Goshawk Nest Site Activity On The Three National Forests In Southern Utah, Keeli Shea Marvel

Theses and Dissertations

The Northern Goshawk has been a species of concern since its decline in the early 1990s, which has been attributed in part to loss of critical breeding and wintering habitat. Nest site selection of goshawks has been correlated with certain specific site characteristics including, but not limited to, forest species composition, forest stand size, diameter of nest tree, percent cover, tree height, site slope, and aspect. The goshawk holds the status of a Management Indicator Species (MIS) on all of the six national forests in Utah. This status requires annual monitoring to track goshawk numbers and to address any activities …

Beneficial Fungal Interactions Resulting In Accelerated Germination Of Astragalus Utahensis, A Hard-Seeded Legume, Sean D. Eldredge

Theses and Dissertations

Seed germination is pivotal in the life cycle of native plants in a restorative context because initiation of the metabolic processes critical to establishment is key to survival in such a competitive environment. Dormancy characteristics of some native plants including the subject species, Astragalus utahensis, have evolved mechanisms to control germination in order to maintain a seed bank and ensure germination at the right time under optimal conditions. In vitro germination studies confirm beneficial interactions between Alternaria and Aspergillus fungi and Astragalus utahensis seed. Inoculated seed trials (1.0 x 106 spores/mL) exhibited a highly significant difference in percent germination between …

It's Alive! The Gothic (Dis)Embodiment Of The Logic Of Networks, Anna Katharine Bennion

Theses and Dissertations

My thesis draws connections between today's network society and the workings of gothic literature in the late eighteenth- and early nineteenth-century. Just as our society is formed and affected by the flow of information, the eighteenth-century culture of sensibility was formed by the merging and flow of scientific "technology" (or new scientific discoveries) and societal norms and rules. Gothic literature was born out of this science-society network, and in many ways embodies the ruptures implicit in it. Although gothic literature is not a network in the same sense as informationalism and the culture of sensibility are, gothic literature works according …

The Role Of Secreted Phosphoprotein-24 In Osteoblast Differentiation And Matrix Mineralization, Samuel Ramage

Theses and Dissertations

Secreted Phosphoprotein-24 (Spp24) was initially isolated and characterized as a component of bovine cortical bone matrix. Subsequent characterization has shown it is multiply phosphorylated and homologous to cystatin and TGF-β receptor type II. Spp24 is a minor component of the serum fetuin mineral complex that binds calcium-phosphate minerals and prevents their deposition. The TGF-β receptor homology domain binds BMP-2 weakly in vitro and enhances BMP-2’s osteogenic effects in vivo. The ability of Spp24 to affect BMP activity suggests an important role for Spp24 as a native, bioactive componentof bone that regulates bone development.

Spp24 was highly up-regulated in rat cortical …

Niche Separation Along Environmental Gradients As A Mechanism To Promote The Coexistence Of Native And Invasive Species, Edmund R. Priddis

Theses and Dissertations

Niche separation may be the key to promoting the long-term coexistence of introduced and native species. Physical alterations to the environment (habitat manipulation) or re-introducing native species to former habitats can exploit the maladapted traits of introduced species to create a refuge for native species. No two species have identical niches because evolutionary constraints differ between species with different evolutionary histories. Our objectives were to determine if cold temperatures could promote coexistence between native least chub and introduced western mosquitofish. We used individual scale and population scale experiments to test four hypotheses: 1) colder temperatures would reduce the aggressive behavior …

Effects Of Water Vapor On The Kinetics Of The Methylperoxy Radical Self-Reaction And Reaction With Hydroperoxy, Alecia Mower

Theses and Dissertations

The gas phase reactions of CH3O2 + CH3O2, HO2 + HO2, and CH3O2 + HO2 in the presence of water vapor have been studied at temperatures between 263 and 303 K using laser flash photolysis coupled with UV time-resolved absorption detection at 220 nm and 260 nm. Water vapor concentration was quantified using tunable diode laser spectroscopy operating in the mid-IR. The HO2 self-reaction rate constant is significantly enhanced by water vapor, consistent with what others have reported, whereas CH3O2 self-reaction and the cross-reaction (CH3O2 + HO2) rate constants are nearly unaffected. The enhancement in the HO2 self-reaction rate coefficient …

Neuronal And Molecular Adaptations Of Gaba Neurons In The Ventral Tegmental Area To Chronic Alcohol, Kimberly Hales

Theses and Dissertations

The purpose of this thesis project was to examine the effects of chronic alcohol on the excitability and molecular adaptation of GABA neurons of the ventral tegmental area (VTA). GABA neurons are of interest with regards to ethanol intoxication, reinforcement, and dependence due to their widespread distribution and connectivity to mesocorticolimbic dopamine (DA) neurons implicated in alcohol reward and addiction. Since we have previously shown adaptation of VTA GABA neuron firing rate to chronic ethanol (Gallegos, Criado et al. 1999) and suppression of gap-junction (GJ) mediated coupling between these neurons by acute ethanol (Stobbs, Ohran et al. 2004), we wanted …

The Population Genetics Of The Wood Frog, Rana Sylvatica, Across Its Geographic Range, Tina M. Squire

Theses and Dissertations

This study aimed to determine the level of genetic variation across the continental-wide range of the wood frog, Rana sylvatica. Levels of genetic differentiation between sampled populations were investigated as was the possible locations of glacial refugia for this species. DNA microsatellites were used as the genetic marker. This study found significant genetic differentiation across the geographic range of Rana sylvatica that increased with geographic distance. In addition three likely glacial refugia, Alaska, New York and the southern Appalachians, were identified.

A subset of the populations used in the geographic range study was used to investigate the patterns at a …

Theses and Dissertations

This study examined time of day effects on the performance of executive function and memory tasks in children with Attention-Deficit/Hyperactivity Disorder (ADHD) and non-ADHD children. Previous studies have found that ADHD children performed worse on executive function and memory tasks. Also, research has found that time of day influences performance on executive function and memory tasks. The data analysis in this present study consisted of comparing the performance of ADHD children tested in the morning, ADHD children tested in the afternoon, non-ADHD children tested in the morning, and non-ADHD children tested in the afternoon on a variety of tests of …

Route Validation Using Radio Frequency Identification, William T. Watson

Theses and Dissertations

In recent years, radio frequency identification (RFID) has been proposed and implemented in a variety of applications where tracking objects, animals or people is desirable. This paper proposes a novel approach to the application of RFID technology in those applications where it is possible to validate a person or an object's passive contact with a given or arbitrary set of fixed points along a predefined route. The notable departure from the typical application of RFID technology is that in this scheme, the transponders are permanently installed while the interrogator is affixed to a person or object that travels the course. …

Rural women tend to be physically inactive and are at higher risk for obesity. The purpose of this case study was to describe and explain 1) the perceptions of rural women regarding rural built environments conducive to physical activity, and 2) what influences availability, accessibility, acceptability, and maintenance of these built environments for physical activity of rural women. March 2006 through April 2007 data collection occurred in two rural communities with populations of less than 1,000. The ecologic model and feminist underpinnings guided …

The Noun Class System Of U̱T-Ma'in, A West Kainji Language Of Nigeria, Rebecca Dow Smith

Theses and Dissertations

This present work provides a comprehensive overview of the noun class system of u̱t-Ma'in, a Benue-Congo (West Kainji) language of Northwestern Nigeria. The u̱t-Ma'in language is characterized by a complex noun classification system and a robust agreement system that permeates the language. While an understanding of the noun classes is essential to an understanding of the language as a whole, discussion includes the division of nouns into thirteen distinct classes, marked by prefixes on the nouns themselves and by agreement elements on other clause constituents. The relationship of the noun classes of u̱t-Ma'in to historical reconstruction work available for the …

Implications Of Introduced Mule Deer On Santa Catalina Island, California : Their Impacts, Population Ecology, And Management, Thad A. Manuwal

Theses and Dissertations

A small group of mule deer were introduced to Santa Catalina Island in the early
1930s. The mule deer population increased through the 1940s and 1950s and remains widespread and abundant today. Large browsing ungulates are not native to Santa Catalina Island and there is concern that nonnative mule deer are damaging endemic trees and shrubs on the island when foraging. This study was designed to develop quantitative information on diets, foraging behavior, movements, and population biology of mule deer on Catalina Island.

Diet analysis indicated mule deer are consuming a wide variety of native and
endemic plants found on …

The aims of this study are chiefly to illuminate the usefulness of existentialism as an important, prescient, and timely methodology for criticism, as well as to reveal the applicability of Kierkegaard's works for literary analysis. There have, prior to this study, been other critical examinations of Shakespeare's work, utilizing the philosophy of Kierkegaard - however, unlike those other works of criticism, this project has undertaken comprehensive analysis of the play, making broad use of Kierkegaard's …

The Berlin Poplars: A Translation, Lene Johansen

Theses and Dissertations

This thesis is a translation of a section of Anne Birkeland Ragde's Berlinerpoplene, or The Berlin Poplars, a contemporary Norwegian novel about how' family dynamics shape and haunt following generations. The narrative alternates between three brothers and reflects how each of them experiences and deals (consciously or not) with feelings of belonging, alienation, and isolation. The Berlin Poplars is a strong novel: the character development and the interpersonal dynamics are rich, and Ragde presents her very flawed protagonists in a dark, brutally honest, yet humane manner. Furthermore, the novel strongly reflects Norway and traditional Norwegian culture.

The complexity of the …

Woody Encroachment In North Dakota Grasslands: Using Predictive Modeling To Examine Key Players And Management Implications, Leigh A. Ciofani

Theses and Dissertations

Woody shrub encroachment is one of the major threats to grasslands, closely connected to other issues such as fire regimes, herbivore grazing patterns, and climate change, and is currently a global trend. Consequences of shrub encroachment can significantly impact many of the ecological characteristics of grasslands, including grassland biogeochemistry and resource availability and biodiversity. Studies conducted on grassland ecosystems have pointed to grassland management, in the form of prescribed burning, grazing, or some combination of the two, as a way to prevent woody encroachment. Prevention of woody encroachment may be particularly important to preserving grasslands, as management may not be …

Quality In The Red River Basin: An Analysis Of Subsurface Drainage, Janet L. Crossland

Theses and Dissertations

The use of subsurface (tile) drainage on poorly drained fields is not a new concept. In fact, farmers in the Midwest have been using it for more than 150 years to remove excess water from saturated fields to increase crop productivity in the Midwest (Cooke, Badiger, and Garcia, 2000). Unfortunately little research has been done regarding tile drainage in North Dakota's Red River Valley (RRV) or how it will affect the surrounding water bodies.

Because of snowmelt or increased rainfall in the summer, the RRV regularly floods in the spring. Prolonged water on the surface can hinder germination as well …

Trapping, Survival, And Probable Causes Of Mortality Of Chukar Partridge, Aaron Clark Robinson

Theses and Dissertations

We present an efficient and effective method for trapping chukars (Alectoris chukar) on artificial water sources. We compared a B-trap, a prairie chicken (Tympanuchus cupido) walk-in trap, a modified quail recall trap, and a newly designed Utah walk-in-funnel trap. Our Utah funnel trap outperformed standard techniques by more than 65%, and exceeded previous published results by 35%. Use of this method allows researchers and managers the ability to capture large numbers of Chukars relatively efficiently. With appropriate modifications this design is applicable for capturing a variety of bird species using small water developments. Chukars (Alectoris chukar) have been introduced throughout …

Mythic Symbols Of Batman, John J. Darowski

Theses and Dissertations

Batman has become a fixture in the popular consciousness of America. Since his first publication in Detective Comics #27 in 1939, he has never ceased publication, appearing in multiple titles every month as well as successfully transitioning into other media such as film and television. A focused analysis of the character will reveal that Batman has achieved and maintained this cultural resonance for almost seventy years by virtue of attaining the status of a postmodern American mythology. In both theme and function, Batman has several direct connections to ancient mythology and has adapted that form into a distinctly American archetype. …

Four Greco-Roman Era Temples Of Near Eastern Fertility Goddesses: An Analysis Of Architectural Tradition, K. Michelle Wimber

Theses and Dissertations

Lucian, writing in the mid-second century AD, recorded his observations of an "exotic" local cult in the city of Hierapolis in what is today Northern Syria. The local goddess was known as Dea Syria to the Romans and Atargatis to the Greeks. Lucian's so-named De Dea Syria is an important record of life and religion in Roman Syria. De Dea Syria presents to us an Oriental cult of a fertility goddess as seen through the eyes of a Hellenized Syrian devotee and religious ethnographer. How accurate Lucian's portrayal of the cult is questionable, though his account provides for us some …

An Evaluation Of A Low-Cost Uav Approach To Noxious Weed Mapping, Brandon Tyler Jones

Theses and Dissertations

Mapping their location and extent is a critical step in noxious weed management. One of the most common methods of mapping noxious weeds is to walk the perimeter of each patch with a handheld GPS receiver. This is the method used at Camp Williams, a National Guard Bureau training facility in Utah where this study was conducted. It was proposed that a low-cost Unmanned Aerial Vehicle (UAV) that made use of a hobbyist remote control airplane equipped with a Global Positioning System (GPS) receiver and digital camera could be used along with automated post-processing techniques to reduce the cost of …

The Ecology Of Translocated Greater Sage-Grouse In Strawberry Valley, Utah, Rick Joseph Baxter

Theses and Dissertations

Manuscript No. 1 Translocations of greater sage-grouse (Centrocercus urophasianus) have been attempted in 7 states and one Canadian province with very little success. To recover a small remnant population and test the efficacy of sage-grouse translocations, we captured and transported 137 adult female sage-grouse from 2 source populations to a release site in Strawberry Valley, Utah during March-April 2003-2005. The resident population of sage-grouse in Strawberry Valley was approximately 150 breeding birds prior to the release. We radiomarked each female and documented survival, movements, reproductive effort, flocking with resident grouse, and lek attendance. We used Program MARK to calculate annual …

Dreamwork With Children: Perceptions And Practice Of School-Based Mental Health Professionals, Rosalia Rodriguez Huermann

Theses and Dissertations

Forty nine public school mental health practitioners (i.e., school counselors, school psychologists, and school social workers) completed a survey about working with dreams when counseling students. Most practitioners in this sample reported having at least one student bring up dreams during counseling and spent some time in counseling working with students' dreams. Practitioners addressed dreams more frequently in situations where the student was having troubling dreams or nightmares, and/or was dealing with death and grief. They also acknowledged working with dreams with students who were diagnosed with Post Traumatic Stress Disorder, were emotionally disturbed, suffered from recurrent dreams, were depressed, …

Applying Bayesian Ordinal Regression To Icap Maladaptive Behavior Subscales, Edward P. Johnson

Theses and Dissertations

This paper develops a Bayesian ordinal regression model for the maladaptive subscales of the Inventory for Client and Agency Planning (ICAP). Because the maladaptive behavior section of the ICAP contains ordinal data, current analysis strategies combine all the subscales into three indices, making the data more interval in nature. Regular MANOVA tools are subsequently used to create a regression model for these indices. This paper uses ordinal regression to analyze each original scale separately. The sample consists of applicants for aid from Utah's Division of Services for Persons with Disabilities. Each applicant fills out the Scales of Independent Behavior"”Revised (SIB-R) …

The Effectiveness Of Prophylactic Eye Drops On The Reversal Of Uv-Light Induced Cataracts, Contessa Bly Bowman

Theses and Dissertations

Cataracts are a cloudiness of the lens within the eye which obstructs vision. They are found in many species including rats, dogs, and humans. Vision is hindered where this "cloudiness", made of water build up and broken crystalline, proteins take form. Oculvet is an eye medication, used by veterinarians, containing carnosine as its active ingredient. Topical application of carnosine is reported to be an effective treatment for the prevention and removal of pre-existing cataracts. For this experiment, Sprague- Dawley rats were anesthetized and exposed to ultraviolet radiation, UVB and UVC. They were divided into four groups (n = 32), three …

Computer-Based Instruction For Engineering Education In The Developing World, Bradford G. Singley

Theses and Dissertations

Although civil engineers continually develop new ways to solve problems involving water, energy, infrastructure and environmental sustainability, these innovations can take years – or even decades – to reach developing countries. Computer-based instruction has the potential to dramatically decrease this lag time by improving engineering education in the developing world. This paper discusses the development of instructional simulations, based on the theory of model-centered instruction. These simulations can serve as self-paced learning modules, which can be accessed for free over the Internet. A pilot learning module was developed for the United Nations Educational Scientific and Cultural Organization (UNESCO) on the …
