Congruence Of Perceptions Of Motivation Between Adolescent Clients, Their Therapist, And Parent, Amberly R. Johnson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study was to explore perceptions of adolescent's motivation to change in therapy, specifically while residing in a residential treatment center (RTC) and participating in family therapy. Motivation for change was examined in three contexts. The first context for examining the adolescent's motivation for change was in relation to their stage of therapy. The second and third contexts for examining the adolescent's motivation for change was in relation to perceptions the adolescent's therapist and parent had of their motivation to change. In addition, the study explored whether there was a relationship between the congruence of perceptions of …

Premarital Preparation And Marital Satisfaction: What Utah Individuals Are Doing To Prepare For Marriage And How Premarital Preparation Can Enhance Marital Satisfaction, Fay L. Belnap Foster

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This is a systematic representative sample study of newlyweds designed to investigate aspects of participation in marriage preparation activities as well as determine what effect participation in activities had on marital satisfaction. A retrospective survey instrument was utilized which included the Kansas Marital Satisfaction Scale.

Statistical analysis revealed that the majority of individuals in Utah prepare for marriage by visiting with parents or relatives, visiting with other married couples, and talking with religious leaders, and considered these activities to be helpful in their preparation. The smaller percentage of individuals who participated in more formal preparation activities also considered these activities …

Comparison Of Water Dynamics In Aspen And Conifer: Implications For Ecology Water Yield Augmentation, Eric Martin Lamalfa

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Differences in water dynamics between deciduous aspen (Populus tremuloides) and co-occurring evergreen conifer species in the Northern Rocky Mountains result from complex physical and biological interactions. A comprehensive evaluation of individual water transfer mechanisms was used to elucidate the relative importance of several components of the hydro logic cycles of aspen and conifer, and determine which water transfer mechanisms have potential to cause differences in net water yield.

Adjacent aspen and conifer stands were monitored to determine snow accumulation and ablation (snow survey), soil moisture recharge (capacitance probes), snowpack sublimation (sublimation pan), transpiration period (thermal dissipation probes), and …

Bats And Mines: Evaluating Townsend's Big-Eared Bat Maternity Colony Response To Reclamation, Gabrielle F. Diamond

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

With the loss or modification of natural roosting habitat afforded by caves, abandoned mines have assumed increased importance as surrogate roosting sites for Townsend's big-eared bats (Corynorhinus townsendii) and other chiropteran species. However, increasing concerns for human safety have led to accelerated programs for mine closure. In efforts to protect roosting sites in mines showing significant bat activity, "bat compatible" gates are installed, thus allowing continued access to mine workings. Aside from ensuring public safety, these structures afford protection from disturbance to roosting bats. To date few posting-gating studies have been conducted to obtain information on the effects …

Breeding Behavior And Space Use Of Male And Female Mule Deer: An Examination Of Potential Risk Differences For Chronic Wasting Disease Infection, Leslie R. Mcfarlane

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The dynamics of pathogen and host relationships relative to disease transmission in wildlife populations are important ecological processes to understand, particularly since spatial dynamics of disease can be driven by movement, behavior, and dispersal of animals. Chronic Wasting Disease (CWD) is an example of this important interface, where little is known regarding origin of the disease or routes of transmission. Surveillance data for CWD in free-ranging mule deer indicates that breeding-age male deer have 2-4 times higher prevalence rates than females or younger age males. In an effort to understand differences that might increase risk for exposure to CWD infective …

Factors Influencing Epiphytic Lichen Communities In Aspen-Associated Forests Of The Bear River Range, Idaho And Utah, Paul C. Rogers

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In western North America, quaking aspen (Populus tremuloides Michx.) is the most common hardwood in montane landscapes. Fire suppression, grazing, wildlife management practices, and climate patterns of the past century are some of the threats to aspen coverage in this region. Researchers are concerned that aspen-dependent species may be losing habitat, thereby threatening their long-term local and regional viability. Though lichens have a rich history as air pollution indicators, I believe that they may also be useful as a metric of community diversity associated with habitat change. To date, few studies have specifically examined the status of aspen's epiphytic lichen …

Evaluating The Effectiveness Of Supplemental Labels In Museum Exhibits, Clint B. Eliason

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The present study used an experimental design to investigate the efficacy of using short (12 words or less), prominently placed supplemental labels to increase the effectiveness of select extant labels in museum exhibits. The experimenter-developed supplemental labels were designed to leverage exogenous/bottom-up and endogenous/top-down sources of influence on selective attention. Measures of patron behavior, knowledge retention, and attitude found no significant differences between group means under control and treatment conditions. These outcomes were surprising and inconsistent with findings from similar research conducted by Hirschi and Screven. The supplemental labels in the present study might have failed to capture attention because …

The Temporal Relationship Between Environmental Factors And Psychological Symptoms In Native American Adolescents, Georgia Lee Matt

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Native American youth often experience high rates of environmental risk factors that may put them at increased risk for developing psychological problems, yet research within this high-risk population is severely limited.

The present study was designed to provide information on the rate of psychological symptoms in a sample of Native American youth, and evaluate the impact of environmental factors (risk, protective, and cultural) on psychological disorder symptoms over time. Data were collected with a sample of Native American youth using the Youth Self Report, the Substance Abuse Subtle Screening Inventory–Adolescent 2, and a researcher-designed Biodemographic Questionnaire.

Findings indicate that clinically …

Effects Of Quaternary Climate Change On Tributary Sedimentation And Geomorphology In Eastern Grand Canyon, Benjamin D. Dejong

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Climate variability has had a dramatic impact on eastern Grand Canyon tributaries over the past ~100 ky. This is readily observed in the Lava Chuar and Comanche catchments, which host well preserved colluvial remnants and river terraces that resulted from several climate-induced cycles of aggradation and incision. This study investigates these climate responses using surveying, sedimentology, and luminescence geochronology methods to investigate the mechanisms and timing of their deposition.

The survey data demonstrate that the concavity of terrace treads is lower than modern drainages. The sedimentology suggests the prevalence of stream-flow reworking of debris flow deposits and portrays an expected …

Hydroacoustic Substrate Classification Accuracy And Faunal Assemblage Variation Between Artificial And Natural Rock Regions: Bear Lake, Utah/Idaho, Mike Moon

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Research designed to elucidate artificial reef efficacy in attraction and production is lacking. Delineation of the rock reef habitat, coupled with faunal patterns of substrate use within artificial and natural reef regions, will allow elucidation of the potential of artificial reefs to attract sport fishes, and function as surrogate natural habitat for the conservation of endemic fish species. We compared faunal assemblages and habitat complexity between artificial and natural reefs to access the efficacy of artificial reefs in conservation of the native community, and attraction of sport fishes.

We used hydroacoustics to map artificial and natural rock reefs within Bear …

The Timing And Magnitude Of Channel Adjustments In The Upper Green River Below Flaming Gorge Dam In Browns Park And Lodore Canyon, Colorado: An Analysis Of The Pre- And Post-Dam River Using High-Resolution Dendrogeomorphology And Repeat Topographic Surveys, Jason S. Alexander

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Channel narrowing on the Green River in Utah and Colorado has been well documented by several authors and has been attributed to reductions in flow after 1930, the construction of Flaming Gorge Dam (FGD), and the invasion of the woody riparian plant Tamarisk (tamarix ramosissima). Narrowing has occurred through the deposition of inset floodplains, which have vertically accreted within a previously larger active channel. Prior to closure of FGD, lower magnitude floods aggraded surfaces in the areas of the channel that had the highest divergence in the velocity flow field (i.e. bars and banks). These surfaces later became …

Dynamics Of Spatial Pattern Formation: Cases Of Spikes And Droplets, Yuya Sasaki

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This thesis studies the gradient system that forms spatial patterns such that the minimum distances of pairs among various points are maximized in the end. As this problem innately involves singularity issues, an extended system of the gradient system is proposed. Motivated by the spatial pattern suggested by a numerical example, this extended system is applied to a three-point problem and then to a two-point problem in a quotient space of ℝ² modulo a lattice.

The Red Top Model: A Landscape-Scale Integrodifference Equation Model Of The Mountain Pine Beetle-Lodgepole Pine Forest Interaction, Justin Heavilin

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Under normative conditions the mountain pine beetle (Dendroctonus ponderosae Hopkins) has played a regulating role in healthy lodgepole pine (Pinus contorta) forests. However, recently eruptive outbreaks that result from large pine beetle populations have destroyed vast tracts of valuable forest. The outbreaks in North America have received a great deal of attention from both the timber industry and government agencies as well as biologists and ecologists.

In this dissertation we develop a landscape-scaled integrodifference equation model describing the mountain pine beetle and its effect on a lodgepole pine forest. The model is built upon a stage-structured model …

Integration, Clarification, Substantiation: Sex, Gender, Ethnicity And Migration As Social Determinants Of Women’S Health, Bilkis Vissandjee, Ilene Hyman, Denise L. Spitzer, Alisha Apale, Nahar Kamrun

Journal of International Women's Studies

The aim of this paper was to examine, via a scoping review, how the literature focusing on immigrant women’s health, based on selected criteria, has been able to capture not only sex and gender differences but also the other socially grounded determinants of health. Using selected health databases as well as a diversity of keywords, a final sample of 59 was obtained after a number of steps to increase validity and credibility of the process were taken. Since “women” was one of the main keywords, all of the studies included women either by themselves (n=20/59) or along with men (n=39/59). …

Pathologizing The Female Body: Phallocentrism In Western Science, Stephanie E. Libbon

Journal of International Women's Studies

In his well-known work Making Sex, Thomas Laqueur contends that the conception of human sexuality evolved from the ancient Greeks’ one-sex model to modernity’s two-sex model as events surrounding the French Revolution prompted a desire to see difference and therefore a need to create difference. In particular, Laqueur argues that it was the struggle for power between those advocating enfranchisement for women and those opposed to this which led to the reconstitution of the human body and in particular the female body. Extrapolating on Laqueur’s assertion that the female was conceived as an inferior version of the male in Antiquity …

The Fortunes And Misfortunes Of Women Rice Producers In Ndop, Cameroon And The Implications For Gender Roles, Lotsmart N. Fonjong, Mbah Fongkimeh Athanasia

Journal of International Women's Studies

In most communities in Cameroon, traditional norms mandate that rural women fulfill the reproductive roles of child bearing, home management and food provision for the family. Thus, these women are unable to exercise any influential economic voice- they can hardly earn income. Cash agriculture like rice production provides a possible outlet for the empowerment of these women in rice producing areas. However, this agricultural work would solve one problem for the women and create another. Any attempt to encourage these women to work outside their homes may increase their workload. This paper examines the situation of female rice farmers in …

Review of The Capacity to Care: Gender and Ethical Subjectivity by Wendy Hollway

China's Nuclear Forces: Operations, Training, Doctrine, Command, Control And Campaign Planning, Larry M. Wortzel Dr.

Books, Monographs & Collaborative Studies

Recent books and journal articles published in China provide new insights into nuclear doctrine, operations, training, and the employment of the People’s Liberation Army’s (PLA) strategic rocket forces. The major insights come from exploiting sections of a doctrinal text published for PLA institutions of higher military education by the Chinese National Defense University, A Guide to the Study of Campaign Theory (Zhanyi Lilun Xuexi Zhinan). In the view of many in the PLA, the military power of the United States, the potential to use that power to coerce or dominate China, and the ability to threaten China’s pursuit of its …

Too High A Price For Some Drugs?: The Fda Burdens Reproductive Choice, Lars Noah

San Diego Law Review

The U.S. Food and Drug Administration has imposed increasingly restrictive conditions on access to pharmaceutical products such as isotretinoin (Accutance) and thalidomide that carry a serious risk of birth defects. This Article focuses on the requirement that female patients agree to use two forms of contraception, drawing parallels to suggestions that similar conditions apply to certain persons on welfare or probation, and posing hypothetical variations of the FDA's access restriction. If anyone ever challenged this aspect of the agency's risk management strategy, a court would have to decide whether the policy (1) grew out of state action (complicated by the …

The Web Of Law, Thomas A. Smith

San Diego Law Review

Scientists and mathematicians in recent years have become intensely interested in the structure of networks. Networks turn out to be crucial to understanding everything from physics and biology, to economics and sociology. This Article proposes that the science of networks has important contributions to make to the study of law as well. The network of American case law closely resembles the Web in structure and can be studied using techniques that are now being used to describe many other networks, some found in nature, and others created by human action. Studying the legal network can shed light on how the …

Continuing The Evolution: Why California Should Amend Family Code Section 8616.5 To Allow Visitation In All Postadoption Contract Agreements, Kirsten Widner

San Diego Law Review

This Comment argues that California should continue the evolution of its statutory scheme by: (1) allowing and enforcing visitation terms in all adoption agreements that meet the statutory requirements of voluntariness and the best interests of the child, and (2) requiring that the consent process inform all birth parents of the possibility of these agreements.

A Novel Cylindrical Punch Method To Characterize Interfacial Adhesion And Residual Stress Of A Thin Polymer Film, Bing Feng Ju, Kuo Kang Liu, Ming Fung Wong, Kai Tak Wan

Mechanical and Aerospace Engineering Faculty Research & Creative Works

Adhesion of a pre-stressed silicone rubber film to a planar graphite surface was investigated by a new cylindrical punch method. a homemade apparatus was constructed to meet force and displacement resolutions of 0.1 μN and 10 nm. When the punch approached the intersurface force range across the punch-film gap, the film jumped into contact at "pull-in". Upon unloading, once the tensile load reached a threshold, a spontaneous delamination occurred at "pull-off" with a non-zero contact circle. a theoretical model was constructed based a simple energy balance. the new method can be used to characterize an adhesion interface between a pre-stressed …

Toward An Understanding Of Serial Killers Through Their Artwork: Implications For Forensic Art Therapy, Kelly Macionis

EVMS School of Health Professions Theses & Dissertations

This research study explored the formal elements and content of 258 images of artwork created by 47 serial killers to see if common themes or content could be discovered. The images were found on five Internet websites containing serial killer artwork. The 47 serial killer artists were all male and it was assumed they were imprisoned when they created their art. The artwork gathered was viewed on a laptop and analyzed using the methods of content analysis. After categories of content and formal elements in the images were entered into a spreadsheet, frequencies and percentages of each category and subcategory …

Optimization Of A New Digital Image Compression Algorithm Based On Nonlinear Dynamical Systems, Anurag R. Sinha

Theses

In this paper we discuss the formulation, research and development of an optimization process for a new compression algorithm known as DYNAMAC, which has its basis in the nonlinear systems theory. We establish that by increasing the measure of randomness of the signal, the peak signal to noise ratio and in turn the quality of compression can be improved to a great extent. This measure, entropy, through exhaustive testing, will be linked to peak signal to noise ratio (PSNR, a measure of quality) and by various discussions and inferences we will establish that this measure would independently drive the compression …

Best Practices In Second Stage Labor Care: Maternal Bearing Down And Positioning, Joyce Roberts, Lisa Hanson

College of Nursing Faculty Research and Publications

Despite evidence of adverse fetal and maternal outcomes from the use of sustained Valsalva bearing down efforts, current second-stage care practices are still characterized by uniform directions to “push” forcefully upon complete dilatation of the cervix while the woman is in a supine position. Directed pushing might slightly shorten the duration of second stage labor, but can also contribute to deoxygenation of the fetus; cause damage to urinary, pelvic, and perineal structures; and challenge a woman’s confidence in her body. Research on the second stage of labor care is reviewed, with a focus on recent literature on maternal bearing down …

Multiplex Snp Discrimination, Daniel J. Fish, M. Todd Horne, Robert P. Searles, Greg P. Brewood, Albert S. Benight

Chemistry Faculty Publications and Presentations

Multiplex hybridization reactions of perfectly matched duplexes and duplexes containing a single basepair mismatch (SNPs) were investigated on DNA microarrays. Effects of duplex length, G-C percentage, and relative position of the SNP on duplex hybridization and SNP resolution were determined. Our theoretical model of multiplex hybridization accurately predicts observed results and implicates target concentration as a critical variable in multiplex SNP detection.

The Microbial Community Structure In Petroleum-Contaminated Sediments Corresponds To Geophysical Signatures, Jonathan P. Allen, Estella A. Atekwana, Eliot A. Atekwana, Joseph W. Duris, D. Dale Werkema, Silvia Rossbach

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

The interdependence between geoelectrical signatures at underground petroleum plumes and the structures of subsurface microbial communities was investigated. For sediments contaminated with light non-aqueous-phase liquids, anomalous high conductivity values have been observed. Vertical changes in the geoelectrical properties of the sediments were concomitant with significant changes in the microbial community structures as determined by the construction and evaluation of 16S rRNA gene libraries. DNA sequencing of clones from four 16S rRNA gene libraries from different depths of a contaminated field site and two libraries from an uncontaminated background site revealed spatial heterogeneity in the microbial community structures. Correspondence analysis showed …

Raman Spectroscopy Of The Human Nail: A Potential Tool For Evaluating Bone Health?, Mark R. Towler, A. Wren, N. Rushe, J. Saunders, N. M. Cummins, P. M. Jakeman

Chemical and Biochemical Engineering Faculty Research & Creative Works

Dual X-ray absorptiometry (DEXA) is the current gold standard for the diagnosis of osteoporosis. However, patients can suffer osteoporotic fractures despite normal bone mineral density, partly because of unmeasured influences of both the protein and mineral phases of bone that are affected in osteoporosis. There is currently no clinically applicable method of evaluating the health of the protein phase. The proteins in human nail (keratin) and bone (collagen) require sulphation and disulphide bond (S-S) formation for structural integrity and disorders of either sulphur metabolism or cystathione beta-synthase can lead to structural abnormalities in these tissues. Raman protein spectra provide a …
