An Exploration Of The Interactions Of Improvers And Deteriorators In The Process Of Group Therapy: A Qualitative Analysis, Laura Lee Hoffmann

Theses and Dissertations

This study examined the interactions of individuals who showed symptom improvement and those who showed symptom deterioration during the course of 12-14 sessions of group process psychotherapy. Both general group themes, as well as themes specific to improvers and deteriorators were found. General group themes included (a) an initial difficulty distinguishing between improvers and deteriorators, and (b) a tendency for group to focus on past or future focus versus present group issues. Specific themes for deteriorators included (a) substantial early disclosure in the group process, (b) open praise of the process of group, (c) the stated expectation of sharing deep …

Land Grabbers, Toadstool Worshippers, And The Sagebrush Rebellion In Utah, 1979-1981, Jedediah S. Rogers

Theses and Dissertations

In 1979, a handful of Nevada state officials sparked a movement to transfer the large unappropriated domain to the western states. For two years what became known as the Sagebrush Rebellion swept across the American West like brushfire, engaging westerners of all stripes in a heated dispute over the question of the public lands. In Utah, as elsewhere in the West, public officials, rural ranchers, miners, developers, academics, environmentalists, and concerned citizens joined the debate and staked sides. This episode underscored western relationships between people and nature and featured contests over competing ideologies in the West. But it probably did …

Experimental And Numerical Investigation Of Tool Heating During Friction Stir Welding, Joshua L. Covington

Theses and Dissertations

The heat input to the tool has been investigated for friction stir welding (FSW) of aluminum alloy AL 7075-T7351 over a wide range of process operating parameters using a combined experimental/numerical approach. In a statistical Design of Experiments fashion, 54 experimental welds (bead-on-plate) were performed at 27 different parameter combinations. Measured outputs during each of the welds included forces in all three coordinate directions and internal temperature of the rotating tool at three locations near the tool/workpiece interface. The heat input to the tool was also identified for each weld using infrared imaging temperature measurement techniques and the portion of …

Cache Characterization And Performance Studies Using Locality Surfaces, Elizabeth Schreiner Sorenson

Theses and Dissertations

Today's processors commonly use caches to help overcome the disparity between processor and main memory speeds. Due to the principle of locality, most of the processor's requests for data are satisfied by the fast cache memory, resulting in a signficant performance improvement. Methods for evaluating workloads and caches in terms of locality are valuable for cache design. In this dissertation, we present a locality surface which displays both temporal and spatial locality on one three-dimensional graph. We provide a solid, mathematical description of locality data and equations for visualization. We then use the locality surface to examine the locality of …

Development Of A Model For The Kinetics And Mechanism Of Nitrogenase, Phillip E. Wilson

Theses and Dissertations

Nitrogenase has a central role in the global nitrogen cycle as the enzyme that catalyzes the reduction of atmospheric N2 to NH3. Fixed nitrogen is generally limiting in the environment and in agriculture, so nitrogenase has received much attention as an alternative to nitrogen fertilizers. Characterizing the mechanism of nitrogenase is the goal of this work. The molybdenum nitrogenase enzyme system is comprised of the MoFe protein and the Fe protein. Interactions between these proteins and nucleotides are crucial to catalysis. An important approach to characterize these interactions is to correlate the kinetics of nitrogenase catalysis to a mechanism based …

Angiotensin Ii-Mediated Regulation Of The Human Angiotensin Ii Type 1 Receptor Gene, Xylophone Vijai Aasee Victor

Theses and Dissertations

The physiological responses of angiotensin II (Ang II) are mediated across the cell membrane through the angiotensin II type 1 receptor (AT1R), a heptahelical membrane protein coupled to trimeric G-proteins on the cytosolic side. AT1R on binding its ligand, Ang II, leads to downregulation of cell-surface receptor and also its mRNA. We have investigated whether the 3'- and 5'-untranslated regions of the human AT1R mRNA mediate the degradation of hAT1R mRNA by post-transcriptional mechanisms in human adrenocortical carcinoma cell line (H295R cells). Protein kinase C (PKC) activator, phorbol-12-myristate-13-acetate (PMA), showed that the downregulation of hAT1R mRNA is mediated by the …

Is The Party Over? Unmarried Fatherhood And Drug And Alcohol Use, Jonathan A. Jarvis

Theses and Dissertations

Using waves two and three of the National Survey of Adolescent Males (1990 and 1995) I examine the effects of marriage, paternity and father involvement on the use of drugs and alcohol by young men. Despite the importance of fatherhood as an adult role, I argue that commitment to the role of fatherhood and not paternity itself is what alters behavior. I hypothesize that young men who assume responsibility for fathering their children are more likely to reduce their drug and alcohol use over time than young men who father children but do not assume the role of parent. Results …

Sandra Cisneros As Chicana Storyteller: Fictional Family (Hi)Stories In Caramelo, Sally Marie Giles

Theses and Dissertations

My thesis discusses the ways in which Sandra Cisneros makes historical claims from a Chicana perspective by telling fictional family stories in Caramelo. Not only have Chicanas traditionally been marginalized ethnically by the Anglo mainstream, they have also suffered disenfranchisement as women in their own male-dominated cultural community. Both elements have contributed to the cultural silencing of Chicanas outside of domestic spaces, and particularly in historical discourse. Cisneros introduces storytelling as a means of empowering Chicanas through language that allows them to speak historically and still signify culturally. By telling stories from the site of the family, she ingeniously utilizes …

Annual Exceedance Probability Analysis, Masako Amai Gardner

Theses and Dissertations

Annual Exceedance Probability (AEP) is the method used by U.S. Army Corps of Engineers (USACE) to determine the probability of flooding caused by the failure of a levee or other flood control structure. This method shows the probability of flooding only at one particular location at a time. In order to overcome the limitation of AEP, a new method of studying flood probability, called an AEP map, was presented. By using hydrologic and hydraulic modeling software, an AEP map can be created to determine and visualize the spatial distribution of the probability of flooding. An AEP map represents a continuous …

Visualizing And Interacting With Externally Coupled Engineering Analysis Results, Paul Frederick Nelson

Theses and Dissertations

Visualizing and interacting with engineering analysis results can provide valuable insights into a system's performance and aid in engineering decision-making. Currently, the majority of analysis codes are developed as isolated solutions focusing only on the most prominent physical influence to a system, such as thermal, structural, fluid, etc. Frequently, more than one of these physical influences combined to force engineers to evaluate complex, coupled systems. Coupled analysis codes are becoming more common place tools for engineers demanding high fidelity simulations of complex systems. External code coupling solutions are emerging to permit generic coupling of separate, world class CAE solvers thus …

Development Of A Weatherproof Windscreen For A Microphone Array, Jeffrey R. Hill

Theses and Dissertations

Microphone windscreens are typically used to reduce the noise associated with wind flowing over a microphone diaphragm by reducing the velocity of the airflow. While most windscreens are effective at reducing this noise, they do not protect the microphone from many natural elements, such as moisture, sand, and other small particles. The focus of this research was to design a windscreen that protects an array of five microphones located around a 4.5-inch diameter cylinder from these natural elements. The design goals were to have a wind noise attenuation of at least 8 dB, an insertion loss of less than 1 …

The Effect Of A Study Abroad On Acquiring Pragmatics, Johanna Katherine Brown

Theses and Dissertations

Pragmatics in Arabic needs to be studied for two main reasons: first, the large cultural difference between American and Middle Eastern society; and second, the recent surge in demand for Arabic speakers in the US. Especially in regard to refusals, what is acceptable in America is rarely acceptable in Arabic speaking countries. There are very few occasions when refusal of an offering of food or other hospitalities is acceptable. Arab culture requires one to provide family members with anything they need, including money. If that is not possible it is required to find the means for what they need. American …

Theses and Dissertations

This creative thesis includes two creative non-fiction essays and twenty-two poems, introduced by a critical essay that examines my work. The poems and essays share an origin in personal experience as well as an interest in language. Specifically, the poems and essays explore issues of family, relationships, spirituality, and observations of the natural world. The introductory essay discusses my interest in re-fashioning individual vision through the act of writing, relating to Helene Cixous's idea of creating a "portrait of God" through the act of art. The essay also examines the connections between the genres of creative non-fiction and poetry, in …

An Examination Of The Role Of Writing In Mathematics Instruction, Amy Jeppsen

Theses and Dissertations

This study uses qualitative methods to investigate the use of writing in a content course for elementary education majors in which writing was considered an important part of mathematical learning. The study differs from previous studies by investigating the role of writing in the everyday instructional activities, rather than investigating writing as a separate mathematical activity. An analysis of the instruction and class discussions that took place in this class reveals that components of writing that were addressed implicitly and explicitly in classroom instruction were developed simultaneously with conceptual understanding, suggesting a much stronger and more integral relationship between writing …

Elevation, Longitudinal Profile, And Schmidt Hammer Analysis Of Strath Terraces Through Capitol Reef National Park, Utah: Bedrock Channel Response To Climate Forcing?, James L. Eddleman

Theses and Dissertations

Elevation, longitudinal profile, and Schmidt hammer data indicate that strath terraces (specifically the lower elevation terraces) mapped in the Fremont River drainage of Capitol Reef National Park are correlative to the terraces of the smaller Pleasant Creek drainage located approximately ten miles to the south. This correlation suggests that drainage development in this area of the Colorado Plateau was strongly dependent upon a regional-scale forcing mechanism (e.g. climate) rather than strictly independent basin-scale processes. Elevations of mapped strath terraces and their associated black volcanic boulder deposits were calculated from geologic maps, Digital Elevation Models (DEM), and Digital Orthophoto Quadrangles of …

Perry Smith And Josef Kavalier: Historical And Literary Victimized Victimizers, Noella Jeo

Theses and Dissertations

In literary trauma theory, victimized victimizers represent an ambiguous area. In my thesis, I show how Perry Smith, a historical figure in Truman Capote's In Cold Blood, and Josef Kavalier, a fictional character in Michael Chabon's The Amazing Adventures of Kavalier & Clay, represent these ambiguities. Both men become murderers acting out violence that was inflicted upon them as children. However, only Kavalier seems to work through the trauma.

Homologous Strand Exchange And Dna Helicase Activities In Plant Mitochondria, Daqing Song

Theses and Dissertations

Homologous recombination is critical for generating genetic variation in living organisms by exchange and rearrangement of DNA. Most of our knowledge about homologous recombination is limited to processes in bacteria or in eukaryotic nuclei. In E. coli, homologous recombination is dependent on the RecA protein. Higher plant chloroplasts have RecA-like strand exchange activity. However, little is known about these mechanisms in higher plant mitochondria. I have detected a RecA-like strand exchange activity in soybean mitochondria. This activity forms joint molecules in the presence of ATP, Mg2+, and homologous DNA substrates. In addition, the E. coli single-stranded DNA binding (SSB) protein …

When The Publisher Is A Politician; A Case Study Of The Idaho Falls Post Register's Coverage Of The 2002 Idaho Gubernatorial Campaign, Kristoffer D. Boyle

Theses and Dissertations

In March 2002, Idaho Falls Post Register owner/publisher Jerry Brady announced his intent to run as the Democratic challenger in the Idaho gubernatorial race. His decision left the newspaper and its editorial staff scrambling for an appropriate way to objectively cover the state's most prominent race involving the man who signed the checks. In an effort to meet this expectation, the newspaper established a detailed plan, which included Brady moving away from the newspaper's operations, both physically and editorially. Additionally, the Post Register brought in an outside media professional to monitor its coverage of the race and hosted several meetings …

Genetic Analysis Of Conserved Residues In Phou Of Escherichia Coli, Stewart G. Gardner

Theses and Dissertations

The Pho regulon is controlled by the PstSCAB transporter, PhoU, and the two-component proteins, PhoB and PhoR. PhoU is a negative regulator of the Pho regulon under phosphate-replete conditions. How PhoU functions is unknown. Many PhoU homologues are found widely throughout prokaryotic domains. There are several conserved amino acid residues in the PhoU protein. It is hypothesized that these residues play an important role in the function of PhoU. To test this hypothesis, several site directed mutations in the phoU gene have been produced with single amino acid changes in conserved residues. After testing these mutants, it was found that …

Time Efficiency In Computer Assisted Direct Observation Of Physical Activity Using Sofit, Trisha Anderson

Theses and Dissertations

Having valid and reliable methods for assessing physical activity levels is critical to understanding physical activity patterns. Direct observation is a widely used technique for obtaining contextually rich data on physical activity levels in physical education classes. One major limitation of direct observation is that it is time intensive. The use of digital video editing software programs may lessen the amount of time needed to gather the data. The purpose of this study was to compare the amount of time needed to obtain SOFIT (System for Observing Fitness Instruction Time) physical activity data using the traditional paper and pencil method …

The Association Between Changes In Body Fat, Body Weight And Serum C-Reactive Protein: A Prospective Study, Benjamin Thomas Bikman

Theses and Dissertations

Objective- To investigate the extent to which changes in body fat percentage (BF%) and weight (BW) relate to changes in C-reactive protein (CRP) in women, while statistically controlling for possible confounders, such as age, initial body weight, and menopause status.

Methods and Results- A cohort of 150 free-living subjects was followed prospectively over a 2½-year period. BF% was measured using dual energy X-ray absorptiometry (DEXA), while BW was determined with a calibrated, electronic scale. There was no significant relationship between changes in BF% and CRP, regardless of age, initial BW, and menopause status. However, changes in BW were predictive of …

Soft Drink Consumption And Changes In Body Composition In 170 Women: A 4-Year Prospective Study, Jared Michael Tucker

Theses and Dissertations

Background: In recent history, there have been significant increases in both soft drink consumption and the prevalence of obesity throughout the developed world. To help curb the obesity epidemic, a better understanding of the behaviors contributing to weight and fat gain is vital.

Objective: To examine the extent to which soft drink consumption is predictive of changes in body composition in middle-aged women over a 4-year period, while statistically controlling for age, energy intake, physical activity, and menopause status.

Design: A prospective cohort design over 48 months with no intervention. Self-reported soft drink consumption was used to predict changes in …

Sibling Influence On Adolescent Cigarette, Alcohol, And Marijuana Use, Benjamin G. Gibbs

Theses and Dissertations

The purpose of this study is to estimate the association between sibling drug use and adolescent alcohol, cigarette, and marijuana use. Research is conducted using survey data from a probability sample of 4,987 adolescents in grades 9–12 in Utah. To account for the limited frequency of drug use among respondents, Poisson regression is used to estimate models for each type of drug. In support of current literature, findings indicate that having a sibling who uses drugs increases the frequency of drug use substantially, even when peer influences are taken into account. Significant sibling associations with adolescent drug use found in …

Materialism, Perceived Financial Problems, And Marital Satisfaction, Lukas R. Dean

Theses and Dissertations

While there has been a relatively large number of studies conducted to investigate associations between financial problems and marital outcomes, little research has been done to examine possible relationships between materialistic attitudes, perceived financial problems, and marital outcomes. This study has been designed to examine a conceptual model linking materialism, perceived financial problems, and relationship satisfaction among married couples. Data obtained from 600 married heterosexual couples who took the RELATE test fit the model well. Findings indicate that wives' materialism is negatively related to husbands' marital satisfaction. Husbands' and wives' materialism is positively related with increased perception of financial problems …

Ionesco's Absurd Anthropology, Deborah Fuller

Theses and Dissertations

Eugène Ionesco's plays are often thought of only as absurd. This thesis explores another possible interpretation of his plays, including Rhinocèros, Le Roi se meurt, Jeux de massacre, Les Chaises, Victimes du devoir, La Jeune fille à marier, and La Leçon. These plays are investigated with the help of anthropologist René Girard's theory on ritual, violence, and sacrifice. Since these elements are recurring themes in Ionesco's plays, Girard's theory is a useful key to unlocking what may seem at times to be nothing but nonsense, but is full of meaning. In the first …

Effects Of Hurricane Fault Architecture On Groundwater Flow In The Timpoweap Canyon Of Southwestern, Utah, Sarah J. Dutson

Theses and Dissertations

Hydrogeologically important features of fault zones include undamaged country rock, the damage zone, and the core zone. Fault cores generally have low porosity and permeability, and often act as a barrier to groundwater flow. The damage zone, by contrast, consists of small faults and fracture networks, which can act as conduits. Timpoweap Canyon near Hurricane, Utah has superb exposures of the fault core and damage zone of the Hurricane Fault. Also within the canyon, springs discharge from the damage zone into the Virgin River, providing an ideal natural laboratory for the study of groundwater discharge from a fault zone. The …

Perceived Impact Of The No Child Left Behind Act Of 2001 On Paraprofessionals, Heather Goodwin Nelson

Theses and Dissertations

Using the states' paraprofessional requirements, this study explored the effects of the No Child Left Behind Act of 2001 (NCLB) on the paraprofessionals' ability to assist in instruction as seen through the perceptions of paraprofessional and teacher teams. The literature review discloses data regarding the implementation of NCLB paraprofessional requirements into the accountability plans of the 50 states and the District of Columbia. Tables synthesize the assessments used by states to meet NCLB paraprofessional requirements. The Council for Exceptional Children performance-based standards for paraeducators provides the framework for the development of two survey instruments, which measured the perceptions of paraprofessionals …

An Examination Of Family Communication Within The Core And Balance Model Of Family Leisure Functioning, Kevin M. Smith

Theses and Dissertations

The purpose of this study was to examine family communication within the Core and Balance Model of Family Leisure Functioning. This was accomplished using path analysis, specifically using a mediator model. Family leisure was measured using the Family Leisure Activity Profile (FLAP), family functioning using the Family Adaptability and Cohesion Evaluation Scales (FACES II), and family communication using the Family Communication Scale (FCS). The sample was youth (n = 90) and parents (n = 123) from 25 different states in the US. Family leisure involvement predicted family functioning variables from the youth and family perspectives, but only partially from the …

The Creation And Formative Evaluation Of An Attachment-Based Parenting Education Website, April Steed

Theses and Dissertations

While there are numerous websites discussing attachment parenting in infancy, there are currently no interactive research-based websites devoted to attachment parenting throughout early childhood. To fill this need the author developed the Foundations of Parenting website (http://www.foundationsofparenting.org). Evaluation, a tool so far under-utilized by parenting education websites, is necessary for both quality control and improving websites. Thus, in addition to development of the website, the author also formatively evaluated the Foundations of Parenting program by using website-utilization tools and visitor feedback through an online survey to analyze utilization and visitor satisfaction. The website was well-used (674 unique visitors and 189 …

Such A Deal Of Wonder: Structures Of Feeling And Performances Of The Winter's Tale From 1981 To 2002, Elizabeth Marie Burt

Theses and Dissertations

Structures of feeling represent the interaction between personal lived experience and fixed social values and meanings, which are found in interpretations of works of art. Studying various interpretations of any play in performance can provide a point of access into a culture because the choices made in the production can be compared to each other and to the written text and then reveal how the theatrical company views particular issues within their own time period. This study looks at productions of The Winter's Tale between 1981 and 2002 at the National Theatre and the Royal Shakespeare Company. Using numerous versions …
