The Effects Of A Self-Monitoring Package Using A Tactile Cueing Device On Student On-Task Behavior In Special Education And General Education Settings, Elizabeth Johnson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Research has shown that self-monitoring can be effective in different settings and with a range of students as well as problem behaviors. However, teachers who use self-monitoring techniques have difficulties in using an effective cueing system as well as generalizing the newly acquired skill into the general education classroom. This study extends the literature by utilizing a tactile cueing device to increase the percentage of intervals of on-task behavior as well as increasing the intervals of on-task behavior in an inclusive general education classroom setting.

The Genetics Of Colonization In Two Amphibian Species After The 1980 Eruption Of Mount St. Helens, Kristin Ann Bakkegard

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The genetics of colonization is understudied in salamanders but has large conservation implications as new habitats are formed or restored to their previous condition. The 1980 eruption of Mount St. Helens provided a natural experiment to study the genetic effects of a large infrequent environmental disturbance on two species of salamander, Taricha granulosa (Rough-skinned newt) and Ambystoma gracile (Northwestern salamander). Both these species breed in ponds, and are thought to exhibit high breeding site fidelity and low vagility. I designated three treatments based on the effects of the eruption: new ponds (created by the eruption, immigrants only), recovery lakes (in …

The Effect Of Climate Change On The Hydrology Of A Mountainous Catchment In The Western United States: A Case Study At Reynolds Creek, Idaho, Anurag Nayak

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This research is focused on understanding the sensitivity of a hydrologic regime at the Reynolds Creek Experimental Watershed (RCEW), a snowmelt dominated semi-arid mountain basin located in southwest Idaho, to climate warming.

Climate data, collected during 1962 to 2006 at many locations in the RCEW, was carefully checked, preprocessed, and corrected for errors and noise signals introduced by the instrument malfunctioning and extreme weather conditions. An Automated Precipitation Correction Program (APCP) was developed to remove mechanical errors from the weighing-recording bucket type precipitation gauge measurements. APCP produces comparable results to the manual techniques but a degree faster (few minutes against …

The Process Of Tracking In Mathematics In Box Elder School District, Megan Haramoto Bushnell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Educational policymakers have used tracking to instruct students in a variety of subjects, including mathematics. Tracking, which has also been called ability grouping, is a process by which students in the same grade are placed into different classes based on academic ability. Few educators and sociologists have looked at the process by which students are placed in different mathematics tracks. The research design of this study focused on accumulating, evaluating, and reporting the understanding and observations of 12 teachers and 4 counselors as they discussed their knowledge and involvement in the mathematics placement procedures from the intermediate and middle school …

Intergranular Phases In Cyclically Annealed Yba2cu3o7-X And Their Implications For Critical Current Densities, Andrew Peter Clarke

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

We report changes in the intergranular material and grain morphology of YBa₂Cu₃O_7-x during cyclic anneals between 780 and 980 ºC in oxygen at atmospheric pressure. Two endothermic reactions were detected: (a) the eutectic reaction of YBa₂Cu₃O_7-x with CuO and BaCuO₂ at 900 ºC (enthalpy ∆H_a) and (b) the peritectic reaction of YBa₂Cu₃O_7-x with CuO at 950 ºC (∆H_b). During the first anneal, only reaction (b) is detected, and although it should only occur if there is an excess of CuO, …

Sex-Biased Predation On Taricha By A Novel Predator In Annadel State Park, Amber Noelle Brouillette

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Newts of the genus Taricha have long been studied due to the powerful neurotoxin found in their skin. Tetrodotoxin (TTX) acts by blocking receptors in sodium channels, ultimately resulting in death via asphyxiation. The only documented predators of species in this genus have been snakes of the genus Thamnophis. Recently, predation on Taricha in Ledson Marsh in Annadel State Park, Santa Rosa, CA was discovered. Predation was in the form of laceration or evisceration, and tracking of predation from 1998-2008 showed that it was male-biased. Two species of Taricha were found living sympatrically at this location, the California newt …

Predator-Prey Relationships And Spatial Ecology Of Jaguars In The Southern Pantanal, Brazil: Implications For Conservation And Management, Sandra Maria Cintra Cavalcanti

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Pantanal wetland of Brazil is an important area for the conservation of jaguars (Panthera onca) and a stronghold for the species. Although our knowledge of jaguar ecology has increased since the first field studies in the mid 1980’s, a detailed study of this cryptic species remains challenging. In the following chapters, we investigated the ecology of jaguars in the southern Pantanal of Brazil. In Chapter II, we examined the foraging ecology of jaguars, documenting predation rates, patterns, and species killed. We found individual jaguars differed in the selection of their prey. There were differences in the proportion …

Predicted Versus Measured Thoracic Gas Volume For The Bod Pod® Air Displacement Plethysmography System, Phil A. Blaney

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study was to determine whether there is a significant difference between measured values of thoracic gas volume (MTGV) and predicted values of thoracic gas volume (PTGV) using the Bod Pod®. One hundred and thirteen college freshmen, both males and females, were tested using the Bod Pod® by first measuring thoracic gas volume with the Bod Pod® technique, then by using pre-determined values based on height, weight, and age that predict thoracic gas volume. Results of a paired t test showed that measured thoracic gas volume and predicted thoracic gas volume were significantly different. A Pearson’s product-moment …

Online Education For Nontraditional Adult Students: Perceptions And Attitudes Of Emergency Services Workers In Asynchronous Learning Environments, R. Jeffery Maxfield

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The goal of this research was to better understand the lived experiences and perceptions of nontraditional, adult college students in an asynchronous online environment. Contemporary researchers have investigated the differences between online education and the traditional, in-class learning. Most of the work has been done in quantitative methodologies, focusing on the similarities and differences in cognitive achievement. The extant literature is replete with studies and positions claiming little or no difference between the two delivery methods. However, most research is not presented in a theoretical construct; therefore, it is difficult to create a nexus between one study and the next. …

Approximations To Continuous Processes In Hierarchical Models, Amanda Cangelosi

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Models for natural nonlinear processes, such as population dynamics, have been given much attention in applied mathematics. For example, species competition has been extensively modeled by differential equations. Often, the scientist has preferred to model the underlying dynamical processes (i.e., theoretical mechanisms) in continuous-time. It is of both scientific and mathematical interest to implement such models in a statistical framework to quantify uncertainty associated with the models in the presence of observations. That is, given discrete observations arising from the underlying continuous process, the unobserved process can be formally described while accounting for multiple sources of uncertainty ( …

Factors Related To Success And Participants’ Psychological Ownership In Collaborative Wildlife Management: A Survey Of Sage-Grouse Local Working Groups, Lorien R. Belton

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Declines of sage-grouse (Centrocercus spp.) across the western United States have prompted the formation of numerous collaborative stakeholder partnerships, known as local working groups. These voluntary groups create and implement local sage-grouse management plans and projects, often in the hopes that their efforts may help avert a federal Endangered Species designation for the bird. Using a mail survey of participants in 54 local working groups, I examined the importance of psychological ownership in working group dynamics. Psychological ownership is conceptualized as a latent, multidimensional variable consisting of responsibility, control, and caring elements. Multiple regression analysis showed early-stage group success, representative …

The Influence Of Debris Cages On Critical Submergence Of Vertical Intakes In Reservoirs, Skyler D. Allen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study quantifies the influence of debris cages on critical submergence at vertical intakes in reservoir configurations. Four model debris cages were constructed of light panel material. A vertical intake protruding one pipe diameter above the floor of a model reservoir was tested in six configurations: open intake pipe, a debris grate placed directly over the intake pipe, and debris cages representing widths of 1.5*d and 2*d and heights of 1.5*c and 2*c, where d is diameter of the intake and c is height of intake above reservoir floor. A selection of top grating configurations and a submerged raft configuration …

Two Highly Diverse Studies In Computing: A Vitruvian Framework For Distribution And A Search Approach To Cancer Therapies, Brian G. Smith

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Solid cancer tumors must recruit new blood vessels for growth and maintenance. Discovering drugs that block this tumor-induced development of new blood vessels (angiogenesis) is an important approach in cancer treatment. However, the complexity of angiogenesis and the difficulty in implementing and evaluating medical changes prevent the discovery of novel and effective new therapies. This paper presents a massively parallel computational search-based approach for the discovery of novel potential cancer treatments, using a high fidelity simulation of angiogenesis. Discovering new therapies is viewed as multi-objective combinatorial optimization over two competing objectives: minimizing the medical cost of the intervention while minimizing …

Reproductive Tactics Of Aphidophagous Lady Beetles: Comparison Of A Native Species And An Invasive Species That Is Displacing It, Yukie Kajita

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Coccinella septempunctata L. (Coleoptera: Coccinellidae) has been introduced to North America in recent decades, raising concerns of adverse impacts on native lady beetles, including the congeneric C. transversoguttata richardsoni (Brown). The central focus of my dissertation is to understand the importance of reproduction, in particular, in promoting invasion of C. septempunctata and its replacement of native lady beetles in alfalfa fields of western North America.

Studies were conducted to compare reproductive tactics of the invasive C. septempunctata and the native C. transversoguttata, by addressing: 1) maximum rate of reproduction of overwintered lady beetles, 2) population dynamics of the invasive …

Inter-Religious Marriage And Migration, Maggie Y. Bohm

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study analyzes the influence of 1) inter-religious marriage and 2) differing levels of church attendance within a married couple on migration behavior. The study draws from previous research on inter-racial marriage for a framework to examine whether there is reason to expect a relationship between migration and inter-religious marriage. We hypothesize that the propensity for migration is higher for inter-religious couples than for couples constituted by individuals of the same religion and for couples who attend church at different frequencies. To examine the hypotheses, this study uses age, education, and length of residence as controls in logistic models.

Diets Of Ladybird Beetles (Coleoptera: Coccinellidae) In Utah Alfalfa Fields, Lynette Nicole Davidson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Aphidophagous lady beetles rely on multiple sources of food in their environment. Alfalfa fields provide both aphids and many alternate foods, such as other arthropod prey, pollen, and fungi. Alfalfa fields (Medicago sativa L.) in Utah have low aphid densities, which may require lady beetles to consume alternative sources of food. Many methods can be used to determine these diets; frass analysis is used here to compare the diets of the introduced species Coccinella septempunctata L. with two native species, C. transversoguttata richardsoni Brown and Hippodamia convergens Guérin-Méneville, that occur in the Utah alfalfa habitat.

In initial laboratory experiments …

Development Of A Post-Fire Monitoring Protocol For Evaluating Treatment Effectiveness And Cheatgrass Abundance Using Quickbird Imagery And Ground Observations, Gabriel Bissonette

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Bureau of Land Management (BLM) manages 9.3 million hectares of land in Utah and has implemented an Emergency Stabilization and Rehabilitation (ESR) Program to protect life and property, combat soil erosion, and reduce the invasion of exotic/noxious weeds following wildland fire. In highly vulnerable sites, seeding treatments may be applied to establish an interim landcover to stabilize the soil and competitively exclude weed invasions. Monitoring treatment effectiveness is mandated through ESR guidelines and necessary for the submission of annual Accomplishment Reports for the first three years following fire containment. Ground monitoring has been the traditional approach to fulfilling this …

Examining The Perceived Benefits For Engaging In Cybersex Behavior Among College Students, Delores D. Rimington

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study examined college students’ cybersex use, perceived benefits of use, time spent online, and compulsive cybersex. Participants consisted of students attending Utah State University Spring semester 2007. Data were collected via an online survey, and 262 surveys were used in the correlation and regression analyses.

Results indicated that age, religion and gender are predictive of perceiving more benefits for cybersex participation. A strong positive correlation was found between perceived benefits and compulsive cybersex use. Students’ lack of social skills was predictive of more time spent online. Time spent online for cybersex was predictive of sexually compulsive behavior. There was …

Cause And Prevention Of Liver Off-Flavor In Five Beef Chuck Muscles, Ranjeeta Wadhwani

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Liver off-flavor is a sporadic problem that limits the consumer acceptance of several beef chuck muscles, including the infraspinatus (flat iron steak). Residual blood hemoglobin is known to contribute to liver off-flavor development. This study was conducted to evaluate factors affecting development of liver off-flavor after cooking of beef chuck (shoulder) muscles. The study was conducted in three parts.

The objective of part 1 was to determine effects of muscle (infraspinatus, longissimus dorsi, serratus ventralis, supraspinatus, teres major) and processing (with or w/o carcass electrical stimulation) on residual blood hemoglobin content and total pigment content of raw muscle …

Development Of A Mathematical Model For 3d Reconstruction Of Target Objects By Photogrammetry, Keith F. Blonquist

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This thesis outlines the development of a mathematical model which can be used to perform 3D reconstruction of a target object from surveillance images. 3D reconstruction is a common procedure in photogrammetry, but performing 3D reconstruction from surveillance images can be more difficult than typical photogrammetry applications.

Surveillance images are generally captured in an unsystematic manner because there is no control over the target that is being photographed. Surveillance images can have a wide variety of fields of view, are often captured with uncalibrated cameras, and typically the targets are objects for which there is no other a priori information. …

Soil Moisture Responses In Traditional And Drought Adapted Landscapes In The Intermountain West, James Gregory

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Water conservation in the Intermountain West will be an important issue in the future as population and demand for limited water resources increases. In Utah, outdoor water use accounts for up to 60% of total per capita water use with 67% of that outdoor water being used to irrigate non native plant species to maintain a uniform green appearance. The objective of this study was to measure intra landscape changes in soil water potential during a 21.5 day dry down from DOY 215 to 236.5 in the summer of 2005 and 2006. Four, 2 x 2 replicated traditional and drought …

Air Demand In Free Flowing Gated Conduits, David Peter Oveson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A physical experimental setup of a circular, gated closed conduit was built at the Utah Water Research Laboratory (UWRL). Setup configurations were modified and data were measured to aid in the study of physical variables on air demand. It was determined that gate opening, gate and water surface roughness, and conduit length all were significant variables on the air demand measured through the conduit air vent. It was also determined that no noticeable air velocity profile existed above the air-water interface. A linear relationship was found between the air flow rate to water flow rate ratio (air-demand ratio) and head-to-gate …

Teaching Creativity In Technical Communication Curricula, Curtis Robert Newbold

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This thesis addresses the need to claim creativity as an essential component to our technical communication curricula as we prepare students for what their managers want. While many technical communication programs at universities across the country have recognized a need to teach skills beyond "writing technically," few, if any, have addressed or "claimed" a concept such as creativity that helps build these skills. I argue that creativity is what managers are looking for and what technical communication programs are already implementing. Claiming this concept will help us further define a discipline that is becoming much richer and help students develop …

Retirement Savings And Types Of Investment Assets Among Near-Retirees Aged 51-64: How Do Women Invest Differently Than Men?, Katrina R. Nye

Analysis Of Effectiveness Of Bridges With Partial Isolation, Wenying Hu

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A special class of seismically isolated bridges shares a common feature in that both ends of the superstructure are restrained and isolators over the columns of bridge uncouple the superstructure from the ground motions. They are defined as partial isolation bridges. From measured acceleration responses, effectiveness of full seismic isolation had been confirmed widely. However, the seismic isolation behavior in the partial isolation has not been widely observed.

The effectiveness of partial isolation is evaluated in this study. The static design procedures for linear and nonlinear partially isolated bridges are developed. Results from the static analysis of linear and nonlinear …

The Impact Of Religious Schema On Critical Thinking Skills, Matthew Kirby

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study was to examine the relationship between critical thinking and religious schema as represented by religious orientation. Past research has included religious belief within the larger construct of paranormal belief, and demonstrated a correlation between high levels of paranormal belief and poor critical thinking skills. Studies in the psychology of religion suggested that a more complex religious measure based on religious orientation was necessary to understand these correlations. Additionally, schema theory offered a cognitive framework within which to experimentally test the cause of these correlations. This study found that primed religious schema did not account for …

Modeling The Electrodynamics Of The Low-Latitude Ionosphere, Christian Stephen Wohlwend

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The electrodynamics of the Earth's low-latitude ionosphere is dependent on the ionospheric conductivity and the thermospheric neutral density, temperature, and winds present. This two-part study focused on the gravity wave seeding mechanism of equatorial plasma depletions in the ionosphere and the associated equatorial spread F, as well as the differences between a two-dimensional flux tube integrated electrodynamics model and a three-dimensional model for the same time period. The gravity wave seeding study was based on a parameterization of a gravity wave perturbation using a background empirical thermosphere and a physics-based ionosphere for the case of 12 UT on 26 September …
