All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study was to investigate Taiwanese adolescent psychosocial development (i.e., autonomy and identity development) based on psychosocial theoretical models developed in western societies. Data were collected from both public senior high and vocational high schools in both urban and rural areas in Taiwan. Adolescent participants, with an average age of 17 years old, included 447 (about 54% were females) from urban areas, and 702 (62% were females) from rural areas. The results of this study revealed that Taiwanese adolescents from both urban and rural areas were similar to adolescent developmental ranges suggested in western theories. There were …

The Effects Of Pedagogical Agents On Mathematics Anxiety And Mathematics Learning, Quan Wei

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study was to investigate the impact of the mathematics anxiety treatment messages in a computer-based environment on ninth-grade students' mathematics anxiety and mathematics learning. The study also examined whether the impact of the treatment messages would be differentiated by learner's gender and by learner's prior mathematics anxiety levels (High vs. Medium vs. Low). Participants were 161 ninth-grade students, who took a required introductory algebra class in a public high school neighboring Utah State University. The learning environment was integrated with a pedagogical agent (animated human-like character) as a tutor. This study employed a pretest and posttest …

The Ability Of The Coping Competence Questionnaire To Predict Resilience Against Learned Helplessness Among Undergraduate College Students: An Experimental Study, Cindy L. Ollis

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Coping Competence Questionnaire (CCQ), based on the reformulated learned helplessness theory, was designed to assess a general stress resistance versus a propensity towards learned helplessness with a brief, 12-item self-report questionnaire. In this study the CCQ was administered to 247 undergraduate students, who were then paired, in groups of around 24 at a time, and then randomly assigned to either success or failure conditions on the computer game TetraVex. Mood was pretested using the Profile of Mood States (POMS) depression subscale; the experimental condition, success or failure at TetraVex was conducted; then outcome measures including 20 five letter anagrams …

Depression Detection In Hospitalized Cardiac Patients, Martine S. Geddes

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Depression has been shown to increase an individual's risk for heart disease. Despite this finding, physicians are not identifying depression in their hospitalized cardiac patients. This study looked at hospitalized cardiac patients and determined whether their physicians were identifying depression in those that scored ≥ 5 on the PHQ-9 depression inventory. Methods included assessing patient depression during their stay at an intensive care unit using the PHQ-9. Those patients scoring ≥ 5 were determined as depressed. Chart audits were performed after the patient discharged from the hospital to discover whether physicians were identifying these patients as depressed. The results showed …

Applying Information Visualization To Computer Security Applications, Robert Bruce Whitaker

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This thesis presents two phases of research in applying visualization to network security challenges. The first phase included discovering the most useful and powerful features in existing computer security visualizations and incorporating them into the AdviseAid visualization platform, an existing software package. The incorporation of such a complete feature set required novel resolution of software engineering, human factors, and computer graphics issues. We also designed additional novel features, such as plugin interfaces, allowing for rapid prototyping and experimentation with novel visualization features and capabilities. The second phase of the research focused on the development of novel visualization techniques themselves. These …

Stormwater Monitoring And Resident Behavior In A Semi-Arid Region, Jennifer Abraham

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The combined effect of land-use alterations and introduced diffuse anthropogenic pollutants to the earth's surface in suburban/urban zones often sparks a decrease in stormwater quality in the area, and contributes to nonpoint source pollution in receiving waters. The ponds at the Utah Botanical Center (UBC) located in Kaysville, UT, regularly experience algal blooms, which in turn cause low dissolved oxygen levels in the waters, indicating high concentrations of inflowing pollutants. The goal of this thesis paper was to describe the findings from the water quality monitoring implemented at both the inlet and outlet of the UBC ponds in order to …

Distributed Renewable Energy Generation And Landscape Architecture: A Critical Review, Osmer Devon Beck

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Governments and utility organizations around the world have mandated and provided incentives for new distributed renewable energy generation (DREG) capacity, and market projections indicate strong growth in distributed renewable energy generation installations in the coming years. New distributed renewable energy generation utilities, by definition, will be primarily located in built environments near consumers; these utilities are often planned and designed by landscape architects, yet no evidence-based, distributed renewable energy generation research is explicitly done by landscape architects or recognizes the role landscape architects play in planning and designing these spaces. The research and analysis provided by this study indicates that …

A Comparative Study To Identify Factors Affecting Adoption Of Soil And Water Conservation Practices Among Smallhold Farmers In The Njoro River Watershed Of Kenya, Steven P. Huckett

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Natural resource conservation is important for human well-being, especially in fragile environments of developing countries. This study occurred in 2006 among 6,500 smallhold farmers residing along a 25-km segment of a heavily utilized river. Research objectives were to determine use and adoption constraints for 14 soil and water conservation practices (SWCPs). Farms were reportedly contributing to a decline in river water quality via soil erosion. Recent occupation of the upper watershed by immigrants magnified concerns that resource degradation could escalate. A multi-method approach incorporating quantitative surveys, qualitative interviews, and participant observation was used to interpret constraining factors within the biophysical …

Commitment, Rituals, And Initiator Tendency In Married Couples, April Bakker

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study was to examine and make explicit the relationships between commitment, rituals, and initiator tendency. Past research and theory suggests that these ideas are related. Two research questions guided the study: (1) How are initiator tendency and the number of rituals a couple participates in related to the commitment style?, and (2) How are initiator tendency and the meaningfulness of rituals related to commitment style?

Data were obtained from 55 couples who completed a questionnaire to measure participation and meaningfulness of rituals, initiator tendency, and commitment. Final analyses were performed with only 39 of these couples …

Arterial Oxygen Saturation As A Predictor Of Acute Mountain Sickness And Summit Success Among Mountianeers, Jonathan R. Knott

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study was to determine if arterial oxygen saturation (SaO₂), as measured by a finger pulse oximeter upon rapid arrival to 4260 m, could be predictive of acute mountain sickness (AMS) or summit success on a climb to 5640 m. In total 73 climbers volunteered to participate in the study. After excluding those taking drugs to counteract the effects of AMS and those with missing data, 48 participants (45 male, 3 female) remained. Climbers were transported from 2650 m to the Piedra Grande hut at 4260 m on Pico de Orizaba within 2 hr. After …

Nga Whaiora Tikanga Roanga: Māori Views Of Health In Utah, Sydney H. Davies

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study looked at the health beliefs of Māori who live in Utah, U.S. and examined what ways those beliefs have evolved from traditional Māori health beliefs. It also looked at the conditions and indicators of those conditions that maintain those health beliefs. A New Zealand study found that Māori older than age 45 years were more likely to have traditional health beliefs, whereas Māori younger than age 45 were more likely to have western-based health beliefs. Using grounded theory, the narratives—from two groups, younger or older than 45 years, where each group was composed of eight randomly selected participants—were …

Fourteen men and 10 women performed the different warm-up protocols, including no warm-up (NWU), static stretching (SS), dynamic stretching (DS), and dynamic stretching with static stretching (DS+SS). The T-Drill was used to assess agility. The results indicated no difference between the NWU and SS conditions (effect size = 0.40, p = 0.06), as well as no significant difference between the NWU and DS+SS conditions …

The Evolution And Implementation Of An Integrated Approach To Emotionally Focused Couple Therapy: A Case Study, Heather Thompson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

There are a number of advantages to working within an integrated model framework when doing family therapy; however, few therapists test what they articulate as their model against what they really do. The purpose of this study was to test how well one therapist practiced her explicated theoretical integration in a clinical setting. Quantitative and qualitative data were gathered to answer three research questions: the level of adherence to the integration, client change, and change within the integrated model over the course of the study. The sample included three couples; data from 25 video-coded sessions, the Revised Dyadic Adjustment Scale …

The Impact Of The Physical Environment On The Social Integration Of Individuals With Disabilities In Community, Keith M. Christensen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Social integration in community is especially important for individuals with disabilities well-being. Although individuals with disabilities reside within the community's physical environment, they are often marginalized in the social environment. This may be the result of individuals with disabilities residing in physical environments that negatively affect opportunities for integration in the social environment. However, there has been little investigation to understand the impact of the physical environment on the social integration of individuals with disabilities in community.

The purpose of this investigation was to (a) examine the current body of evidence concerning the impact of a community's physical environment on …

Examination Of Behavioral Momentum With Staff As Contextual Variables In Applied Settings With Children With Autism, Mark P. Groskreutz

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Behavioral momentum theory proposes that the persistence of behavior when exposed to disruptors provides an appropriate measure of the strength of behavior. Basic research has consistently demonstrated that behaviors that occurred in a context with higher overall rates of reinforcement (rich contexts) were more persistent than other behaviors that have occurred in a context with relatively lower rates of reinforcement (lean contexts). More surprisingly, behavioral momentum theory goes on to assert that this greater persistence in richer contexts is found even when rate of responding is lower in the rich context, and when the greater richness is due to noncontingent …

Language Brokering In Latino Families: Direct Observations Of Brokering Patterns, Parent-Child Interactions, And Relationship Quality, Kee J. E. Straits

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

With the growing percentage of immigrant families in the USA, language transition is a common immigrant experience and can occur rapidly from generation to generation within a family. Child language brokering appears to occur within minority language families as one way of negotiating language and cultural differences; however, the phenomenon of children translating or mediating language interactions for parents has previously been hypothesized to contribute to negative outcomes for children, such as role-reversals and parentification, emotional distancing and lack of communication, increased parent-child conflict, and increased internalizing/externalizing disorders. The current study used direct observations of 60 Spanish-speaking parent-child dyads (30 …

The Impact Of Knowledge, Attitudes, And Peer Influence On Adolescent Energy Drink Consumption, Alyson C. Ward

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Adolescents are labeled as sensitive to caffeine, though despite this predisposition, consumption is high among this population. Energy drinks are a current trend in soft-drink-like beverages and are marketed to 11-35 year olds. However, unlike soft drinks, energy drinks are not regulated by the Food and Drug Administration, and therefore do not have to limit their caffeine content.

This cross-sectional, correlational study sought to identify the role that knowledge, attitudes, and peers play in adolescent energy drink consumption. Adolescents (n = 199), ages 18 to 21, at a university in the west were surveyed. Descriptive statistics revealed that 25% …

Factors Associated With Physical Activity Behaviors Among Rural Adolescents, Kenli A. Urruty

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The "obesity epidemic" in the United States is a current health concern that has sparked research interest in physical activity as a means of weight management. However, little research has examined the physical activity behaviors of rural adolescents. The goal of the current study was to use a biopsychosocial framework to examine the physical activity behaviors of a sample of rural adolescents, and explore factors associated with physical activity participation.

A sample of 162 ninth- and tenth-grade students in a rural, western community were recruited for this study. Generally, the sample reported levels of physical activity for both genders that …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study was to examine change in symptoms of anxiety and satisfaction experienced by participants who received acceptance and commitment therapy (ACT) by using technologically assisted psychotherapeutic interventions (TAPI). TAPI utilizes the internet as a medium to make mental health services available and accessible to people residing in rural communities. The participants in this study were women who were experiencing severe levels of anxiety and lived in a rural community. Measures were taken at three different points in the study (pretherapy, posttherapy, and 6-months posttherapy). Participants received therapy over the internet via Macromedia Breeze videoconferencing to reduce …

Cell Phone Use And Psychosocial Development Among Emerging Adults, Torrey B. Morrill

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The cell phone has rapidly become an integral, and, for some, an essential communication tool that is being used worldwide. With cell phone ownership becoming so widespread, especially among the younger generation, society is starting to see and question the impacts of cell phone use on adolescent development.

Relations between cell phone possession, cell phone use, and psychosocial and identity development were investigated using Erikson's Psychosocial Theory and Marcia's Adolescent Identity Paradigm. A sample of 705 college students, ages 18-24, completed a questionnaire that measured the amount and type of cell phone use, identity development (Extended Objective Measure of Ego …

Patterns Of Psychosocial Functioning And Mental Health Service Utilization In Children And Adolescents With Chronic Health Conditions Or Physical Disabilities, Sara M. Hunt

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study was designed to further understand the psychosocial functioning of youth with chronic health conditions or physical disabilities, their need for and use of mental health services, and possible barriers to receiving needed services. Previous research has suggested these youth experience poorer psychosocial functioning compared to peers without special health care needs, and they also underutilize needed mental health services. A mixed-methods design was implemented consisting of a quantitative parent survey and a qualitative semistructured interview with young adults with special health care needs.

Children demonstrating poorer psychosocial adjustment in this study experienced more problems related to social functioning …

The Cult Of True Motherhood: A Narrative, Jacoba Lynne Mendelkow

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This thesis consists of five chapters including a traditional introduction and four chapters, which investigate cultural interpretations of motherhood within the genre of memoir and personal essay. In the introduction, I discuss my research as it relates to the larger collection and detail how this work is different from other works within the "mother memoir" genre. Chapters II thru V, then, are all essays which begin to explore the major themes of cultural motherhood: ambivalence, loss, legitimacy, morality, and sin. These chapters, especially chapter II, identify and detail the traits of true motherhood as patience, compassion, sacrifice, and strength.

Consistency Of Cognitions In Remarriage: A Test Of The Consistency Tenet Of The Multidimensional Cognitive-Developmental Model, Janae Elise Campbell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Remarriages have been increasing over the last several decades, yet little has been done in establishing theories and interventions specific to remarried couples and stepfamilies. Fine and Kurdek proposed a model specific to individuals in a remarriage situation. In an effort to validate their model, this study tested a key tenet, the tenet of consistency in cognitions, across spouses. Data were analyzed from the "Relationship Quality and Stability in Utah Newlywed Remarriages" study. With a sample of 449 couples, a series of correlations and backward regressions were completed. The results indicate that individual perceptions are more predictive of remarital quality …

An Empirical Investigation Of The Adaptive Nature Of Shame, Elizabeth Jacqueline Dansie

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Throughout the empirical psychological literature on emotion, the general consensus is that shame is maladaptive, while guilt is the adaptive moral emotion. Conversely, evolutionary psychology concludes that all emotions serve adaptive functions. Specifically, shame serves an appeasement function in social relationships. In order to investigate the true nature of shame, the current study used an experimental design. Specifically, a 2 (high shame, no shame) X 2 (high guilt, no guilt) design with a no-mistakes control group was implemented, and shame and guilt were operationalized through an evolutionary lens (i.e., shame as a nonverbal display, guilt as verbalizations of apology). Participants …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study was to investigate social science doctoral students' perceptions and attitudes toward different characteristics of written feedback and written feedback providers for their academic writing. Moreover, it aimed to provide an explanatory model to describe the relationships between these perceptions and attitudes, students' revision decisions, and other potentially relevant factors in their written feedback practices. The investigation was informed by two theoretical frameworks: principles of instructional design and conditions of learning, and situated learning and communities of practice.

The study used a mixed methods approach in which qualitative data collection and analysis was followed by quantitative …

An Evaluation Of The Allocation Of Funding For Assistive Technology: A Case Study, Cindy L. Ollis

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Although benefits of assistive technology (AT) to people with disabilities are widely apparent, barriers, primarily funding, still inhibit access to needed AT. All agencies receiving federal funding are required to show no discrimination with regard to age, race, disability, and gender. This case study of a state run agency providing funding for AT to enable independent living among people with disabilities involved analyzing spending data from 2003 2008 to determine who used the fund, what was purchased, and whether it was equitably distributed according to age, ethnicity, gender, and population density. Additionally variables predictive of amount spent per person were …

The Effect Of An Ambient Olfactory Intervention On Time-On-Task And Performance During Participant Interaction With An Electronic Flashcard System, Aaron J. Loewer

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study was to measure the influence of an ambient peppermint aroma on participants' time-on-task and performance while using FACTOR, an open-source e-Learning application. I proposed time-on-task was moderating between olfactory stimulation and performance.

A 2x2 research design measured interaction of group (nonscented, scented) and gender of participants (N = 65). The learning content consisted of 28 African countries. Two methods for measuring time-on-task were employed: participant self-report at six learning intervals, and second, video recordings captured by, and stored on each participant's computer.

Independent samples t tests were used to measure group and gender differences …
