Catalytic Pyrolysis Of Olive Mill Wastewater Sludge, Hamza Abdellaoui

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

From 2008 to 2013, an average of 2,821.4 kilotons/year of olive oil were produced around the world. The waste product of the olive mill industry consists of solid residue (pomace) and wastewater (OMW). Annually, around 30 million m³ of OMW are produced in the Mediterranean area, 700,000 m³ year⁻¹ in Tunisia alone. OMW is an aqueous effluent characterized by an offensive smell and high organic matter content, including high molecular weight phenolic compounds and long-chain fatty acids. These compounds are highly toxic to micro-organisms and plants, which makes the OMW a serious threat to the environment if …

The Role Of Medical Comorbidities On The Risk For Severe Dementia, Institutionalization, And Death In Alzheimer's Disease: A Population Study In Cache County, Utah, Mac J. Gilbert

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Alzheimer’s disease is a progressive disease that impairs cognitive and functional abilities. Without a cure, it is estimated there will be 81 million cases of Alzheimer’s disease by 2040. Life for the individual with Alzheimer’s disease, and their family, changes drastically when the affected individual experiences significant problems with memory, thinking, and ability to complete daily tasks. Some become so debilitated that they need to be placed in a nursing home for supportive care. Until a cure is discovered, it will be important to identify what can be done to help those with Alzheimer’s disease minimize time spent experiencing severe …

Effects Of Differential Rates Of Alternative Reinforcement On Resurgence Of Human Behavior: A Translational Model Of Relapse In The Anxiety Disorders, Brooke M. Smith

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Brooke M. Smith, graduate student in the Combined Clinical, Counseling, and School Psychology program at Utah State University, proposed and completed this thesis in partial fulfillment of the requirements of Master of Science in Psychology.

Anxiety disorders are the most common psychological disorders in the world, and they place a substantial burden on society. Although successful psychological treatments for anxiety are available, many people still experience relapse once treatment ends. When consequences that follow a behavior increase its future probability, this is termed “reinforcement.” One common treatment approach for anxiety is to attempt to decrease problematic behavior, such as avoidance, …

The Relationship Of Trait Mindfulness And Positive Mental And Physical Health Among College Students, Sarah A. Potts

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Mindfulness interventions have become an increasingly popular psychological intervention for mental health providers, especially in Westernized countries. Mindfulness interventions are promising in terms of possibly reducing physical and mental health symptoms among a wide variety of clients (including college students) presenting diverse diagnoses. While a number of studies suggest that mindfulness interventions increase mindfulness ability, as demonstrated by an increase in awareness, attention to the present moment, or other components of mindfulness, this assertion has not been validated because many researchers utilizing a mindfulness intervention fail to include measures assessing change in trait mindfulness ability. The present study examined mindfulness …

The Effects Of Brief, Localized, Intensive, Social Skills (Bliss) Training On Social Outcomes For Students With Autism Spectrum Disorder In Inclusive School Settings: Form And Function, Christian V. Sabey

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study examined the impact of a framework for implementing social skills training, entitled BLISS, on the social vocalizations of students with autism spectrum disorder.

The number of students with autism spectrum disorder is on the rise and many of these students are being served predominantly in general education settings. However, there is a serious lack of social skills training interventions that have been effectively integrated into the typical school setting, including the use of typically available school personnel as interventionists. The developers of the BLISS approach take a step closer to the ideal by integrating brief social skills instruction …

An Evaluation Of Group Activity Schedules To Train Children With Autism To Play Hide-And-Seek With Their Typically Developing Peers, Jessica S. Akers

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Children with autism spectrum disorder have difficulties with social and play skills. The purpose of this study was to determine if three young children with autism could learn to play a complex social game, hide-and-seek, with three typically developing peers. Participants were taught to play hide-and-seek using photographic activity schedules. Photographic activity schedules are a type of visual schedule that teach children with autism to engage in chains of behavior. Two schedules were present during
teaching sessions, a seeker schedule and a hider schedule. Each group member played the role of the seeker once during the game. The three participants, …

Romantic Relationship Quality And Technological Communication: Examining The Roles Of Attachment Representations And Rejection Sensitivity, Ron C. Bean

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

It is important to understand normal developmental patterns in romantic relationships, which develop within historical and cultural contexts and are influenced by social and technological advancement. One of the core features of developing attachment in romantic relationships is proximity to the attachment figure, for which technology may be a substitute. This study described patterns of computer-mediated communication (CMC) in young adult relationships. We hypothesized that core relational and personality features were linked to participants’ interpretations of CMC.

For this study, 97 college students provided overall scores for rejection sensitivity, insecure attachment styles, relationship satisfaction, and data about CMC with their …

A survey was sent to graduates of a teacher preparation program at a large, land-grant university, who were embarking on their novice year of teaching. Responses were received from 16 teachers. In the survey, teachers were asked to answer demographic questions regarding …

Spatial Patterns Of Rural And Exurban Residential Settlement And Agricultural Trends In The Intermountain West, Saleh Ahmed

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Population growth is often linked to negative impacts on agriculture. However, the effects of residential development likely depends on the spatial pattern of development, such as whether housing is clustered or dispersed, and whether it is located near or away from important farmland. For several decades, rural and urban planners have advocated policies to encourage consolidated forms of development as one strategy to protect agriculture and preserve open space. To date, relatively little empirical research has been conducted on the actual effects of different spatial patterns of residential settlement on agricultural. This study aims to fill that gap with a …

Negotiated Settlement And The Durability Of Peace: Agreement Design, Implementation, And Mediated Civil Wars, Chong Chen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Since the end of the Cold War, outright military victories in civil wars have been rare. As a result, the number of peace agreements designed to end civil wars in the post-Cold War era has increased exponentially compared to the entire Cold War period. However, according to some statistics, about a third of those peace agreements failed to secure postwar peace. These failures to get warring parties to live up to their peace agreements not only restarted armed conflict, but they also escalated the violence. Therefore, this project is aimed to explore why some civil war settlements break down within …

Dementia Caregiver Personality Traits And Coping Strategies: Association With Care Recipient Outcomes, Christine M. Snyder

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study examined the potential impact of dementia caregivers’ personality traits and utilization of coping strategies on care recipients’ development of severe dementia, institutionalization, and mortality. Generally, the personality traits and coping strategies were not predictive of care recipient outcomes, especially related to the institutionalization of care recipients. However, increased caregiver use of Avoidance predicted time to care recipient development of severe dementia, while increased use of Counting Blessings reduced risk of mortality.

This research was conducted using extant data from a community-wide study examining factors that affect dementia progression. All data were collected by a research nurse and a …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Understanding factors that influence teachers to use certain practices from training they receive will help improve learning experiences for students. This study examined how two teachers with the same teacher training experience use learning from that training in their instruction differently. This research attempted to account for multiple factors that influenced teachers learning. Educator’s incorporation of teaching practices can vary from teacher to teacher and from training to training. This variability is understood in terms of their appropriation of new teaching practices into their teaching and delivery of learning. Two teachers were selected as a result of their participation in …

Understanding Myth And Myth As Understanding: An Interdisciplinary Approach To Mytho-Logic Narration, Sandra Bartlett Atwood

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

I wanted to see if there were points of overlap between the various accounts of creation found in folklore, philosophy and physics. In order to justify such a project, I initially considered literature from each of these disciplines regarding the necessity of interdisciplinary dialogue generally and specifically the need for both intuition and logic when considering how anything actually exists. Through my research and casual observation, I hypothesized that opposition seemed to be a universal characteristic of nature. I then looked at how each discipline has described fundamentally opposing pairs and created a list of primary features that those accounts …

Sexual Orientation Change Efforts, Identity Conflict, And Psychosocial Health Amongst Same-Sex Attracted Mormons, John P. Dehlin

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Both religiosity and sexuality are acknowledged by the American Psychological Association as important considerations for overall psychosocial well-being. Consequently, the denunciation of same-sex sexuality as sinful by many religious organizations leads many lesbian, gay, bisexual, and transgender individuals to experience significant identity conflict. Historically, conservative religious institutions such as The Church of Jesus Christ of Latter-day Saints (Mormons) have offered
developmental (i.e., nonbiological) explanations as to the origins of same sexuality, along with various nonaffirming approaches including: (a) sexual orientation change efforts, (b) increased religious devotion, (c) celibacy, and (d) mixed-orientation (heterosexual) marriage. However, relatively little research has been conducted …

The Legend, The Madman, And The Prophet A Memoir About Fathers And Sons, Erik K. Thalman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Legend, the Madman, and the Prophet is a memoir about fathers and sons, about the experience of being a son of a man of the Rocky Mountains, a legend grown old. The narrative centers around my struggle with the fact that my father had grown old and sick while I was still young, and my consequent search for other fathers, employing two primary examples—a martial-arts instructor from my high-school years who was later exposed as a pedophile, and the eccentric figure of my ex-girlfriend’s wealthy and traditional Egyptian-American father. The memoir relates the story of my father’s impact on …

African American Female Engineering Students' Persistence In Stereotype-Threatening Environments: A Critical Race Theory Perspective, Stacie Lesure Gregory

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

African American women are grossly underrepresented in engineering. Despite their low representation in engineering colleges, some are able to persist and earn their degrees. This qualitative study sought to better understand the strategies 10 African American women employed to help them remain resilient in engineering degree programs. For this investigation, there was an underlying assumption that African American women who persist in engineering must contend with stereotype threat. Stereotype threat is a psychosocial phenomenon in which people in stigmatized social categories fear confirming negative stereotypes about their group.

Ten African American female women who have persisted in engineering degree programs …

These programs were designed to help them increase PN ratios when interacting with students during homework time in the after-school program. Group 1 received only the …

How Arizona Community College Teachers Go About Learning To Teach, Carolyn J. Hamblin

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

New Arizona community college teachers go through a transformative learning process when they learn to teach. They enter the classroom with preformed ways of thinking about teaching. These habits of mind include what they imagine a community college teacher to be. They expect their knowledge and expertise to translate into teaching ability and they are shocked to learn that this is not the case. Classroom teaching involves basic pedagogical skills such as preventing cheating, creating appropriate tests, planning a course calendar, and pacing a lecture. The discomfort that accompanies this revelation causes the teachers to think critically about what good …

Who Cares? Developing A Pedagogy Of Caring In Higher Education, Andrew Shayne Larsen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

When students are asked about their motivation to succeed in a course, about whether they enjoyed their instructor, and about their overall satisfaction with the class, answers can often be traced back to an educator who was perceived by the student as caring. Perceived caring occurs when a student feels that a teacher’s positive behaviors directed toward the student are motivated by good intentions and good will.

Research in the area of teacher care has almost exclusively focused on elementary and secondary classrooms, and has advanced the theory that caring teachers and caring classroom environments prompt many positive educational outcomes. …

The Relationship Between Attachment, Couple Conflict, And Recovery From Conflict, Nathan C. Taylor

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Advances in technology have opened the door for increased understanding to the physiological changes that influence and are influenced by conflict. The objective of this research was to use these advances in technology to better understand the relationship between attachment and physiological reactivity during conflict, as well as during recovery from couple conflict. Skin conductance equipment was used to measure 10 couples (n = 20) physiological arousal while discussing an area of conflict, and during a recovery section which included a relationship distraction task and discussion. Five multiple regressions were used to analyze physiological reactivity during and after conflict …

"Wires And Lights In A Box": Fahrenheit 451 As A Product Of Postwar Anxiety About Television, Christine V. Shell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This project discusses the ways in which Ray Bradbury’s novel Fahrenheit 451 functions as an indictment of media culture. While many analyses of the novel focus on the text’s sweeping themes of literary censorship, this study instead centers on Bradbury’s depiction of media—particularly television—culture and the ways in which Bradbury feared it could be harmful. Although Bradbury wrote about a future society a century beyond his own, his novel serves as a remarkable reflection of his contemporaneous culture’s media consumption and gendered divisions; this thesis discusses Bradbury’s novel alongside such forces, considering the effects such influences may have had on …

The Impact Of Social Support, Psychosocial Characteristics, And Contextual Factors On Racial Disparities In Hypertension, E. Miranda Reiter

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Hypertension is a serious medical condition. Although men and women of all racial groups in the US suffer from high blood pressure, black women have the highest rates of hypertension. For instance, the age-adjusted prevalence of hypertension among black women ages 20 and over is 44.3, compared to 28.1 among white women, 40.5 among black men, and 31.1 among white men.

Past research has focused on SES and behavioral factors as potential explanations for blood pressure disparities between black and white women. But, even after controlling for such factors, considerable disparities remain. The goal of this research is to examine …
