Analysis Of A Functional Heterologous Chromosomal Replication Origin Transplant In E. Coli, Rohit Pradip Kadam

Theses and Dissertations

To ensure that all cells replicate their genomes faithfully before they divide, the initiation step of chromosome replication must be tightly regulated during the cell cycle. In bacteria, new rounds of replication are triggered by the assembly of a higher order protein complex, termed the orisome, that unwinds a well-defined origin (oriC) region on the circular chromosome, and prepares it for new replication forks. Orisomes comprise multiple copies of a highly conserved initiator protein, DnaA, and instructions for ordered orisome assembly are encoded into the oriC nucleotide sequence of nearly all bacteria as specifically-spaced clusters of 9 base pair (bp) …

The Evolutionary Significance Of Body Size In Burying Beetles, Ashlee Nichole Momcilovich

Theses and Dissertations

Body size is one of the most commonly studied traits of an organism, which is largely due to its direct correlation with fitness, life history strategy, and physiology of the organism. Patterns of body size distribution are also often studied. The distribution of body size within species is looked at for suggestions of differential mating strategies or niche variation among ontogenetic development. Patterns are also examined among species to determine the effects of competition, environmental factors, and phylogenetic inertia. Finally, the distribution of body size across the geographic range of a species or group of closely related is looked at …

Survival Of Neonate Mule Deer Fawns In Southern Utah: Effects Of Coyote Removal And Synchrony Of Parturition, Jacob Tyler Hall

Theses and Dissertations

Mule deer (Odocoileus hemionus) are an iconic species of wildlife, and populations of mule deer across much of the western U.S. have experienced recent fluctuations in size. Factors that affect the survival and subsequent recruitment of juveniles may be the preeminent cause of population fluctuations for mule deer in many areas. Many factors, including habitat loss, extreme weather, intense predation, timing and synchrony of parturition, and competition with other species may be influencing these changes. We studied two potential factors that can influence the survival of neonate mule deer in southern Utah. To better understand how predation affects …

Authentic Purposeful Design Within Moral Spaces Of Teaching At Byu, Thomas Lane Ferrin

Theses and Dissertations

This thesis is an exploration of the role of a new course design method in the teaching practice of faculty at Brigham Young University (BYU). This method, used by teaching and learning consultants at BYU, is termed authentic purposeful design. It encourages faculty to succinctly define what their course will help students become, use principles of backward design to align all course elements to that purpose, and teach the course with its core purpose in mind.

Food Discourse: The Communicative Gateway Toward Understanding Formerly Colonized Representation In Parts Unknown, Mitch Combs

Theses and Dissertations

CNN’s television series, Anthony Bourdain: Parts Unknown, merges food and travel genres to communicate representations of local, indigenous, and other formerly colonized cultures. This thesis will present the significance of Parts Unknown through a review of literature that concerns postcolonial theory and food discourse to which critical insights emerge and explain how indigenous cultures are represented within Western “foodie” television. These insights will then guide a postcolonial investigation of the food rhetoric used to represent/discuss colonized and local groups within three episodes of Parts Unknown. Additionally, potential applications for rhetorical criticism are discussed by using Parts Unknown as an example …

The Impact Of Mentoring At- Risk Youth On The Socialization Process Of Pre-Service Teachers, Theresa Allgaier

Theses and Dissertations

While much is known about how traditional field based practical experiences in teacher preparation programs impact the socialization of pre-service teachers, less is known about how practical experiences within after-school programs and other contexts influence pre-service teacher socialization. Relatedly, many scholars have sought to understand at-risk youth and have investigated teachers’ experiences with these students within the context of schools and the gym. The purpose of this study was to understand how mentoring at-risk youth in an after-school program impacted the socialization of six pre-service teachers. Occupational Socialization Theory provided the theoretical framework for this study. Six PETE majors, in …

Human Optimization And Performance Enhancement In Flight Via Real-Time Biofeedback (Project Have Hope), Michael S. Fritts

Theses and Dissertations

A four-phase, chronological, and build-up approach was implemented that commenced with basic hardware testing in a centrifuge and culminated in flights augmented by real-time biofeedback displays. A prototype Portable Electrocardiogram Unit (PECGU) was designed and proven to accurately measure heart rate (HR) and display percent heart rate reserve (%HRR). Results showed that %HRR was not a sole predictor of cognitive state. Cognitive responses indicated some correlation with %HRR, but were influenced by environment (centrifuge vs. flight). Subjective perceived exertion levels did not show statistically significant changes during test with biofeedback. A G-tracking task was evaluated during centrifuge and flight tests. …

Framed Text Messages As A Nutrition Education Intervention, Michael James O'Halloran

Theses and Dissertations

A youth’s college years is a critical period in health behavior formation, during which body mass index (BMI) and other health behaviors such as diet and physical activity are strong predictors of adult health status. Text messaging is prominent in the lives of most college-age adults. Despite this, relatively few studies have investigated the potential of utilizing a text message-based intervention to target fruit and vegetable consumption, a measure for weight management behaviors. Additionally, few studies utilizing a text message-based intervention have utilized a theory specific to the creation of behavior-motivating text messages. The gain-framed health behavior messages of Prospect …

Effects Of Foliar Applied Titanium ( Ti ) On Quality And Nutrient Uptake Of Creeping Bentgrass ( Agrostis Stolonifera ) On Professional Golf Course Greens, Caleb Wepprecht

Theses and Dissertations

Golf course putting greens typically consist of creeping bentgrass on sandy soils. Creeping bentgrass is mowed at extremely short heights, limiting root growth and making it vulnerable to different pests. Sandy profiles make it difficult for creeping bentgrass to take up nutrients and water. Tytanit combines sulfur, magnesium, and titanium-ascorbate as a biostimulant to increase chlorophyll content within the plant, increase yields, and assist in fighting biotic and abiotic diseases such as diseases and drought. Previous studies have shown benefits in plant growth, but results have been inconsistent. No previously reported studies have been performed on turfgrass using Tytanit. Therefore, …

The purpose of this research was to investigate the use of in-ear noise dosimetry and worker feedback to reduce noise exposures among combat arms instructors and heavy equipment operators in the Air Force. Specifically, this thesis sought to determine how effectively hearing protection devices (HPDs) are being utilized currently, and whether providing at-ear noise exposure data to workers results in reduced noise exposures or changes in worker attitude. These questions were addressed by performing a six-month field study using dosimeters to record worker noise exposures under HPDs. Subjects served as their own control, receiving feedback in only the latter half …

Learning And Behavior In Hatchling Trachemys Scripta Exposed To Bisphenol-A During Embryonic Development, Justin E. Dillard

Theses and Dissertations

Steroids play an integral role in orchestrating embryonic development, and can affect a suite of phenotypic traits, including learning and memory. Endocrine disrupting compounds (EDCs) can mimic the effects of steroids and can affect the same suites of phenotypic traits during embryonic development. Bisphenol-A (BPA) is an EDC that mimics the action of estrogen, and recent work is beginning to implicate BPA in effects on learning and behavior similar to those caused by estrogen treatment studies. Red-eared slider turtles (Trachemys scripta) are a good system to investigate the effects of BPA on learning and behavior, both because the molecular underpinnings …

Faith Too Big To Fail? The Struggles And Wishes Of New Atheism, Joe Rice

Theses and Dissertations

After September 11th, 2001, public criticism of religion took front and center stage in the United States like never before, epitomized by the works of Ayaan Hirsi Ali, Richard Dawkins, Daniel Dennett, Sam Harris, and Christopher Hitchens – the so-called “New Atheists”. In this thesis, I reunderstand the New Atheism as an oppositional social movement that promises important contributions to the recent trend in academic scholarship geared toward the study of religion and secularism. Reunderstanding is essential because the mainstream scholarly treatment of the New Atheism has not fully, much less charitably, drawn out the purpose and upshot of New …

Latent ;Toxoplasma Gondii; Infection Moderates The Association Between The C677t Mthfr Polymorphism And Cognitive Function In U.S. Adults, Andrew Nathan Berrett

Theses and Dissertations

Sufficient blood concentrations of folate and the products from its metabolism arenecessary for several cellular functions. The C677T MTHFR polymorphism, present in over halfof the U.S. population, reduces the efficiency of folate metabolism and has been linked to theonset of multiple psychiatric disorders and cognitive decline. The intracellular parasiteToxoplasma gondii can infect the human brain and is associated with increased prevalence ofpsychiatric disorders and cognitive decline. In vitro studies have found that Toxoplasma gondiimay salvage unmetabolized folate from host cells. Since the C677T MTHFR polymorphism andinfection by Toxoplasma gondii both affect folate metabolism or availability, I used data fromthe third …

Assessing Parenting: Adaptation Of The Home Inventory For Use In Egypt, Khadiga Abdellatif Alsharif

Theses and Dissertations

A study of violence against children in Egypt found that in 2014, 93% of children between the ages of 0-14 were subject to some form of violent discipline. While Egyptian law protects children from abuse, in practice it is challenging for social workers and other child protection practitioners to intervene. There is a lack of protocols for home visitation and family intervention, and there are no standardized procedures for assessing parenting practices and determining the safety of children’s homes. The HOME inventory, short for Home Observation for Measurement of the Environment, is a tool that has been adopted internationally and …

An Investigation Into The Test-Retest Reliability Of The Scale Of Accurate Personality Prediction With A Six Week Interval, Jared Marshall Barrow

Theses and Dissertations

The Scale of Accurate Personality Prediction (SAPP) is a measure to determine the accuracy of an individual’s ability to predict his/her own personality traits. Previous studies have demonstrated the validity of SAPP as a measure, and this study serves as one in a series of study on the reliability of the SAPP. To establish the test-retest reliability of the SAPP, the SAPP scores of 22 participants were calculated from two testing trials separated by a six week interval. A Pearson correlation indicated a significant correlation of moderate strength between the SAPP scores from the two testing trials (r=.572, p<0.01). The implication of these results within the context of the previous test-retest reliability studies and limitations to the current study are discussed.

Dietary Sodium And Blood Pressure Changes In Hemodialysis Patients Undergoing A Liberalized Renal Diet Intervention, Lauren Eve Chan

Theses and Dissertations

Objective: Investigate the impacts of individual liberalized renal diet counseling in conjunction with a volume reduction hemodialysis (HD) protocol.

Design & Methods: Twenty-three maintenance HD patients (age = 55.7 ± 13.3y, 47.8% female), consented and completed this pilot intervention. Across the six-month intervention, participants received thrice weekly dietary counseling about a liberalized renal diet. Liberalized renal dietary guidelines promoted a low sodium diet with greater unprocessed food consumption, decreasing foods eaten outside the home, and increased food label reading. Participant HD sessions were conducted per a volume reduction protocol, gradually decreasing patient post-dialysis weight by removing an additional 200-300 mL/session. …

A Qualitative Case Study On Delegation Of School Nursing Practice: School Nurses, Teachers, And Paraprofessionals Perspectives, Sharon L. Schofield

Theses and Dissertations

For the past decade, there have been many changes to school nursing with the implementation of unlicensed assistant personnel now known as paraprofessionals. This process has brought about several concerns such as mode of delegation, education, training, ability to monitor health-care needs, and organizational effects that trended downward without direction. This qualitative inquiry gave an interpretative meaning to the process of delegation in school nursing, the factors that hinder the delegation process as well as components that are needed to effectively delegate and utilize support staff (paraprofessionals) without detrimental effects to students. This study interviewed 20 participants.

Results of this …

An Examination Of A Mindfulness-Based Intervention For Older Adults, Morgan Levy

Theses and Dissertations

Mindfulness-based interventions use meditation and other learning exercises to help individuals become more aware of their current physiological and emotional experiences. Benefits of practicing mindfulness include an increase in positive psychological outcomes (e.g., psychological well-being, emotion regulation) and a decrease in negative psychological outcomes (e.g., anxiety, depression). The vast majority of studies focus on younger rather than older adults—setting the stage for the current study, which involved delivering a five-session mindfulness-based intervention to older adults (i.e., 60 and older). The smaller literature focused on older adults is promising but generally lacks methodological rigor (e.g., lack of no-treatment control groups). The …

The Role Of Ceramide In Neutrophil Elastase Induced Inflammation In The Lungs, Sophia Karandashova

Theses and Dissertations

Alterations to sphingolipid metabolism are associated with increased pulmonary inflammation, but the impact of inflammatory mediators, such as neutrophil elastase (NE), on airway sphingolipid homeostasis remains unknown. NE is a protease associated CF lung disease progression, and can be found in up to micromolar concentrations in patient airways. While sphingolipids have been investigated in the context of CF, the focus has been on loss of cystic fibrosis transmembrane conductance regulator (CFTR) function. Here, we present a novel observation: oropharyngeal aspiration of NE increases airway ceramides in mice. Using a previously characterized mouse model of NE-induced inflammation, we demonstrate that NE …

Association Between Polypharmacy And Functional Status In Community-Dwelling Older Adults, Duaa M. Bakhshwin

Theses and Dissertations

Background: Polypharmacy has no consensus definition in the literature. Previously used definitions include those based on the number of medications and those based on unnecessary or inappropriate medication use. Polypharmacy has been associated with increased risk of disability and functional limitations that impair a person's ability to live independently. Older adults are a population of interest as they are at increased risk for both polypharmacy and functional impairments. Understanding the relationship between polypharmacy and functional impairment in older adults could help health care providers and policy makers to target an at-risk population for interventions.

Objectives:

1. To assess the relationship between …

“We’Re All In This Together:” Exploring The Effectiveness And Responsiveness Of Nonprofits In Promoting The Socioeconomic Integration Of Refugees, Brittany Keegan

Theses and Dissertations

When a person is forced to flee their home due to violence or the fear of persecution, they must seek refuge elsewhere – either within the borders of their home country or in a new country. Those who travel to another country in search of safety and protection are known as refugees, and as world conflicts continue, the number of refugees around the world is steadily increasing. As refugees integrate into their new communities, they often receive support from nonprofit organizations once government assistance has ceased. This mixed method study uses 60 open-ended, first-person interviews with refugees and nonprofit service …
