Thirty-two canine tibiae with patellae and patellar tendons were harvested from 17 skeletally mature cadavers. Each tibia was randomly allocated to a construct group: plate and pin (Plate), plate with countersink compression screw (HCS), plate with tension band (TB), or plate with HCS and TB (HCSTB). Samples were loaded by distraction until failure. The stiffness, yield load, and ultimate load were compared between each fixation method. No difference in stiffness of the constructs was detected between groups. Yield load and ultimate load for the HCSTB group was greater than the TB group, the HCS group, and the Plate group. CBLO …

Development Of A Crosslinked Osteochondral Xenograft And A Collagen Stabilizing Intra-Articular Injection To Remediate Cartilage Focal Lesions To Prevent Osteoarthritis, Mark Lewis Mosher

Theses and Dissertations

Osteoarthritis is one of the most common causes of disability in adults in America. It is a progressive and degenerative disease where the articular cartilage is broken down and lost from the surfaces of bones causing chronic pain and swelling in the joints, and currently has no cure. The most commonly osteoarthritis starts from a focal lesion on the cartilage surface, which will expand on the surface and downwards through the thickness of the tissue. The current gold standard for correcting cartilage focal lesions is the osteochondral autograft/allograft transplantation (OAT), which replaces the defect with a fresh osteochondral graft. The …

The Effect Of Childhood Maltreatment On Psychotherapy Effectiveness In Adulthood: Implications For Counselors, Michael Hillerman

Theses and Dissertations

Recent gains in understanding the effects of childhood maltreatment on the development of the brain and nervous system, combined with the revelation that nearly all psychiatric neuroimaging studies have had an unrecognized confound in childhood maltreatment, imply the possibility that psychotherapy treatment effectiveness studies have been similarly confounded by childhood maltreatment. This study examines whether treatment-seeking adults exposed to childhood maltreatment respond differently to psychotherapy than do individuals who report no history of childhood maltreatment. Response to therapy is conceptualized in this study as reduction in symptom measures pre- and post- treatment, as well as client dropout. It is hypothesized …

Taste is one of the crucial factors that contributes to shaping eating behaviors and is also one of the leading reasons that affects our preferences to like or dislike some foods that mainly have a bitter taste. Variation in bitter phenotype (tasters and non-tasters) could influence diet quality and in turn body weight, which overall influenced health outcomes. The objective of this study was to identify whether bitter taste phenotype status influences anthropometric measurements, body fat percentage, and eating behaviors (liking and intake) in female college students. In this cross-sectional study (n = 86), female college students aged 18 to …

Parent-Child Relationships And Parental Distress As Moderators Between Chronic Illness And Psychological Problems In Emerging Adults., Abigail Kukay

Theses and Dissertations

The current study aimed to better understand how parental functioning and parent-child relationships might moderate the effects of chronic illness on psychological problems in emerging adulthood. Three hypotheses were made: (1) the presence and severity of chronic illness would associate positively with emerging adult psychological problems, (2) parental distress would moderate the effects between chronic illness presence/severity and emerging adulthood psychological problems, and (3) parent-child relationship quality would moderate the effects between chronic illness presence/severity and emerging adult psychological problems. Data analysis consisted of testing interaction effects, pairwise parameter comparisons, and multiple group analysis. The three-way interaction between endorsing a …

Experiences And Perspectives Of Women Veterans Use Of The Veterans’ Health Administration Services, Leanne Anthon

Theses and Dissertations

Women make up 10% of the veteran population. With a projected increase of up to 16% by 2043, this is the fastest-growing demographic in the US military (National Center for Veterans Analysis and Statistics, 2017). This population may have experiences unique from their non-military counterparts such as military sexual trauma (MST), environmental exposures, post-traumatic stress disorder (PTSD), and stress related to their military occupation that may predispose this group to decreased quality of life (QOL). In recent years, the Veterans Health Administration (VA) healthcare system has attempted to increase the healthcare accessibility and services provided to the growing number of …

Arab American Muslims’ Attitudes Toward Seeking Mental Health Services: The Roles Of Acculturation, Religion, And Cultural Beliefs, Tharwah Alzoubi

Theses and Dissertations

The purpose of this study was to identify the relationship between acculturation, religion, cultural beliefs, and attitudes toward seeking mental health services among Arab American Muslims. A total of 280 participants were surveyed for this study. Regression analysis was conducted to explore relationships among the variables; the alpha level was set at .05. The first research hypothesis was accepted as it showed statistical significance in the relationship between attitudes toward seeking mental health services and demographic variables. The standardized regression coefficients, or beta coefficients ranged from -.008 for gender to .24 for marital status, R=.31 (P<.05). Two variables were significant at the .05 level (marital status, and health insurance). The second hypothesis was also accepted as it showed relationship between attitudes toward mental health services and acculturation, religion and cultural beliefs; the standardized regression coefficients, or beta coefficients ranged from .05 for cultural beliefs to a -.25 for religion, R=.44 (P<.05). The variables of acculturation and religion were significant at the .01 level. Cultural beliefs were not significant at .05 level.

Orthographic Knowledge And Phonological Awareness In Children With Speech Sound Disorder, Anna Marie Ehrhorn

Theses and Dissertations

Speech sound disorder (SSD) puts children at risk for word reading difficulties but does not guarantee them. Research on early literacy skills in children with SSD has primarily focused on phonological awareness due to speech sound deficits associated with SSD. Researchers have begun to examine multiple factors beyond phonological awareness that may impact word reading and spelling development. Orthographic knowledge is another essential factor understudied in children with SSD. Previous research has shown that orthographic properties of words influence phonological awareness performance in skilled readers and children with reading difficulties. No known previous studies have examined whether orthography influences phonological …

Neighborhood greenspace is important for health and well-being but may not be equitably present in neighborhoods across the United States. Also, many adults are physically inactive, have obesity, and report poor health-related quality of life. Greenspace has been tied to these health conditions, but with mixed findings. The purpose of this study was to 1) use an environmental justice perspective to examine variations in 11 measures of greenspace by neighborhood race/ethnicity, income, and rurality in block groups across the contiguous United States and 2) examine 11 greenspace measures in connection to physical activity, obesity, and health-related quality of life in …

Behavioral And Neurophysiological Measures Of Speech Auditory Feedback Processing Impairment In Left Hemisphere Stroke, Stacey Sangtian

Theses and Dissertations

The purpose of this study was to identify behavioral and neural correlates of impaired speech auditory feedback processing in people with a history of left-hemisphere stroke (LHS). To do this, we used the altered auditory feedback (AAF) paradigm to externally induce speech errors by randomly shifting the pitch frequency of the online auditory feedback up or down at ±100 cents in 38 LHS and 27 neurologically intact control participants under two experimental conditions: 1) active vocalizations of a steady speech vowel sound “ah,” and 2) passive listening to the playback of the same self-produced vocalizations. Randomized control trials were included …

Nutrition Facts Label Use Among U.S. Adolescents, Jennifer Beth Mandelbaum

Theses and Dissertations

Despite the promise of Nutrition Facts label (NFL) use as a population-level intervention with broad reach, few studies have examined determinants of adolescents’ NFL use, and how this label use may be associated with nutrition behaviors. This study used data from the International Food Policy Study, an online cross-sectional survey of trends in dietary patterns and policy-relevant behaviors in the U.S. and five other countries. First, this study examined 1) whether NFL use was associated with healthy eating efforts and 2) whether there were sociodemographic differences in NFL use among U.S. adolescents. Results demonstrated that NFL use was positively associated …

Peromyscus Maniculatus Bairdii And Peromyscus Maniculatus Sonoriensis Polymorphisms, Matthew Dixon Lucius

Theses and Dissertations

Sequencing technology has advanced greatly over the past couple of decades. This has led to many studies developing hypotheses based on genomic data. This requires many genomic studies to have up-to-date information on the species’ or subject’s genome being investigated. If a study does not have accurate or up-to-date background information, then they cannot fully develop their theories that are being established. In this study, I utilize outbred Peromyscus maniculatus, deer mice that are genetically diverse, to record the polymorphisms that are found throughout the Peromyscus maniculatus genome. I first explore the differences between the polymorphisms found in Peromyscus …

Genomic Analysis Workflows To Identify Mutational Signatures And Structural Variations In Ovcar8 Cells And Rad51d-Deficient Mouse Embryonic Fibroblasts, Manli Yang

Theses and Dissertations

Specific genomic profiles associated with exposure to DNA damaging agents have been identified in cancer related genes, revealing that mutational patterns can be carcinogen- specific. However, there have been limited efforts to demonstrate similar clear relationships for endogenous mutational processes. One endogenous source of mutations is contamination of the deoxynucleotide pool with damaged bases that, if incorporated into DNA, cause mutations.

The Catalog of Somatic Mutations In Cancer (COSMIC) represents an international effort to characterize mutations in cancer. A mutational signature is the pattern of mutations generated by a mutational process. Each mutational process contains two parts: DNA damage and …

Assessment Of Postural, Locomotor, And Physical Fitness Status In Individuals With Intellectual And Developmental Disabilities, Alana J. Turner

Theses and Dissertations

Introduction: Postural control and locomotion deficits can be observed during the early years of childhood development and throughout life. For those with disabilities, these deficits can advance past the development years and into adolescence and adulthood while affecting the quality of life and daily activity. Finding interactive rehabilitative activities to delay or limit these deficits is essential for people with disabilities to improve their quality of life, inclusion, and overall movement. Adapted physical activity/sports like badminton and virtual reality could promote improvements in postural and locomotor status for young adults with intellectual and developmental disabilities like cerebral palsy (CP), intellectual …

Ex Vivo Biomechanical Evaluation Of A Novel Screw For Tibial Plateau Leveling Osteotomy, William Seth Kettleman

Theses and Dissertations

Twelve pairs of cadaveric pelvic limbs were harvested from skeletally mature dogs. Tibias were randomly assigned pairwise to two study groups: locking buttress screw fixation (LBS) and bone-screw-fastener fixation (BSF). A tibial plateau leveling osteotomy (TPLO) was performed. Each specimen was positioned in a servohydraulic testing machine to simulate physiological orientation and loading at the mid-point of the stance phase at the walk. Cyclic loading was performed for 30,000 cycles at 4Hz with a peak-load of 1000N. The cyclic test was then continued by stepwise increasing the peak-load at a rate of 75N per 500 cycles until failure of the …

Ex Vivo Biomechanical Comparison Of A Novel Compression Screw Fastener And Traditional Ao Cortical Bone Screw For Fixation Of A Simulated Slab Fracture In The Equine Third Carpal Bone, Allison Salinger

Theses and Dissertations

Frontal plane slab fractures account for the majority of third carpal bone (C3) fractures in performance horses. Treatment is stabilization with an AO cortical screw. Complications are fragment splitting, fragment spinning, and irritation of dorsal soft tissue structures. A novel, headless, cannulated screw with interlocking threads (the Headless Compression Screw Fastener, HCSF) has been developed to resist multidirectional forces. Simulated C3 slab fractures were created in nine paired equine carpi. HCSF or AO cortical screws were loaded in shear to failure. Stiffness, maximum load to failure, and yield load was assessed in linear mixed models. No significant difference was detected …

Wearable Activity Trackers For Women: Motivating Factors For Increasing Physical Activity, Danielle A. Bate

Theses and Dissertations

Half of American women do not sustain recommended levels of physical activity (PA). Wearable activity trackers (WATs) may increase both awareness of, and PA if worn daily. Thus, WATs should include features and designs that encourage daily use. This study aimed to determine WAT features and designs most appealing to women and the motivational effects of various WATs. For this mixed-method pilot study, 15 women each trialed three WATs; documented daily PA levels; and rated their satisfaction with each device's comfort, features, and motivational effect. Additionally, participants shared experiences and feedback in focus groups. Features that promote adoption of WATs …

Impacting Positive Breastfeeding Attitudes Of Prelicensure Nursing Students Using An Evidence-Based Breastfeeding Module, Stephanie D. Uhr

Theses and Dissertations

Background: Robust evidence demonstrates optimal breastfeeding behaviors provide unmatched short- and long-term health outcomes. Therefore, breast milk feeding is more than a feeding decision; it is a significant public health concern. Breast milk is species-specific nutrition for a developing infant. The health impact of providing breastmilk extends to the lactating parent. However, the existing breastfeeding education is often inadequate to support the care of the breastfeeding dyad. The dissertation examines the role breastfeeding plays in prelicensure nursing education and analyzes the use of an evidence-based breastfeeding educational module (EBBM) on breastfeeding attitudes.Method: An integrative review analyzed the current state of …

In almost every country, public health officials forced and/or encouraged Nonpharmaceutical Interventions (NPIs) such as contact tracing, social distancing, masks, and quarantine. Human behavioral decision-making regarding social isolation significantly impedes global success in containing the pandemic. This thesis focuses on human behaviors and cultures related to the decision-making of social isolation during the pandemic. …

Effects Of Macronutrients Intake And Physical Activity On Childhood Obesity Of Hispanic Children, Prosanta Barai

Theses and Dissertations

Obesity has become more ubiquitous during the past few decades, and still, its prevalence is increasing. It is in every population in the world and all regions, including rural parts of low and middle-income countries. In the USA, regardless of age, the severity of obesity is no different from the global trend. Although numerous pieces of literature are available, that tried to find answers to some pressing issues like how obesity can be controlled, but there is little to no study focused on younger children, especially the 4-6-year-old Hispanic population. Our study aimed to determine the causal path among literature …

Impact Of Teacher Cognition On The Implementation Of Social- Emotional Learning Practices For El Students, Madeline Bliske

Theses and Dissertations

There is a well-established achievement and graduation rate gap between English Learner (EL) students and their monolingual English-speaking peers (U.S. Department of Education, 2020). The current study focuses on teacher cognition and characteristics that may impact the likelihood that they will implement culturally and linguistically sustaining (CLS) social-emotional learning (SEL) practices for EL students within their classroom. Specifically, I descriptively analyze whether personal, professional, or school characteristics are associated with teachers’ perception of EL students SEL competencies or implementation of CLS SEL practices. Utilizing the Theory of Planned Behavior (TPB), I evaluate whether teacher cognition (i.e., behavioral attitudes, subjective norms, …
