Comparison Of Obesity Bias, Attitudes, And Beliefs Among Undergraduate Dietetic Students, Dietetic Interns, And Practicing Registered Dietitians, Sarah E. Welborn

Electronic Theses and Dissertations

The obesity epidemic in the United States is increasing, and health concerns are also on the rise as they are directly related to obesity. Even though the majority of Americans are overweight or obese, prejudice and weight bias continue to be prevalent and socially accepted in a culture that tolerates discrimination towards these individuals. Health care providers, including registered dietitians, are not exempt from instigating bias towards obese patients causing a decrease in the level of care that they receive. The main purpose of this study was to compare attitudes, beliefs, and bias concerning obesity among undergraduate dietetic students, dietetic …

Assessment Of Dietary Behaviors Of College Students Participating In The Health Promotion Program Bucs: Live Well, Courtney E. Mckinney

Electronic Theses and Dissertations

Rates of adult obesity in the United States continue to rise, especially among the college-age population who typically practice poor dietary choices, contributing to weight gain. College-age students experience a transitional phase called ‘emerging adulthood’ where they learn autonomy in many areas that influence long-term health status. The purpose of the online health promotion program BUCS: Live Well was to promote self-efficacy in ability to incorporate positive dietary changes, assess incidences of positive dietary habits after completing the program, and determine if weight status, residence, and health perceptions influence dietary behaviors. BUCS: Live Well was successful in assessing current dietary …

Detection Of Bacterial Retroelements Using Genomics, Sen Mu

Electronic Theses and Dissertations

The reverse flow of genetic information can occur when a special DNA polymerase called Reverse Transcriptase (RT) copies the genetic information in an RNA molecule back into a complementary DNA. One type of RT encoding gene found in bacteria is called a retron element. Recent bacterial genome sequencing projects have revealed many examples of retron RT genes. This gene assignment is based on comparison with a few known retron RT proteins. However, RT proteins are highly diverse in their amino acid sequences, and thus the assigned identity of these RT proteins as retrons in genome databases is questionable. One way …

Very Cost Effective Partitions In Graphs, Inna Vasylieva

Electronic Theses and Dissertations

For a graph G=(V,E) and a set of vertices S, a vertex v in S is said to be very cost effective if it is adjacent to more vertices in V -S than in S.

A bipartition pi={S, V- S} is called very cost effective if both S and V- S are very cost effective sets. Not all graphs have a very cost effective bipartition, for example, the complete graphs of odd order do not. We consider several families of graphs G, including Cartesian products and cacti graphs, to determine whether G has a very cost effective bipartition.

Academic Achievement Of Elementary Students: A Comparison Study Of Student Athletes Versus Nonathletes, Kimberly R. Dyke

Electronic Theses and Dissertations

The place of sports in academic institutions has been analyzed at length for several years. However most studies focus on the participation of high school and university students in school sports. Very little research exists to suggest a positive or negative correlation between academic achievement and participation in interscholastic sports at the elementary level. As a result the relationship between academic performance and participation in school sports among elementary students in grades 4 and 5 was investigated in this study. Through an independent-samples t test analysis of 1,605 fourth and fifth grade boys and girls, it was determined that students …

Study Of Immobilizing Cadmium Selenide Quantum Dots In Selected Polymers For Application In Peroxyoxalate Chemiluminescence Flow Injection Analysis, Christopher S. Moore

Electronic Theses and Dissertations

Two batches of CdSe QDs with different sizes were synthesized for immobilizing in polyisoprene (PI), polymethylmethacrylate (PMMA), and low-density polyethylene (LDPE). The combinations of QDs and polymer substrates were evaluated for their analytical fit-for-use in applicable immunoassays. Hydrogen peroxide standards were injected into the flow injection analyzer (FIA) constructed to simulate enzyme-generated hydrogen peroxide reacting with bis-(2,4,6-trichlorophenyl) oxalate.

Linear correlations between hydrogen peroxide and chemilumenscent intensities yielded regression values greater than 0.9750 for hydrogen peroxide concentrations between 1.0 x 10^-4 M and 1.0 x 10^-1 M. The developed technique’s LOD was approximately 10 ppm. Variability of the prepared …

Preventing Skin Cancer In Adolescent Girls Through Intervention With Their Mothers, Mary K. Baker

Electronic Theses and Dissertations

Indoor tanning (IT) before the age of 35 increases one’s risk for melanoma by 75%, and epidemiological data show a 6.1% annual increase in the incidence of melanomas in white women younger than age 44 in the US. Population-based studies reveal that 15% of adolescents and 8% to 14% of their primary caregivers have engaged in IT in the past year.

The compelling case for IT being a significant risk factor for melanoma, together with the high rates of IT in teen girls and their mothers, provided a strong rationale for conducting an antitanning intervention directed at mother-daughter dyads. This …

Analysis And Mitigation Of The Cubesat Dynamic Environment, Steve M. Furger

Master's Theses

A vibration model was developed for CubeSats inside the Poly-Picosatellite Orbital Deployer (P-POD). CubeSats are fixed in the Z axis of deployers, and therefore resonate with deployer peaks. CubeSats generally start fixed in the X and Y axes, and then settle into an isolated position. CubeSats do not resonate with deployers after settling into an isolated position. Experimental data shows that the P-POD amplifies vibration loads when CubeSats are fixed in the deployer, and vibration loads are reduced when the CubeSats settle into an isolated position. A concept for a future deployer was proposed that isolates CubeSats from the deployer …

The Relationship Between Vitamin D Status Of Adult Women And Diet, Sun Exposure, Skin Reflectance, Body Composition, And Insulin Sensitivity, Marisa M. Mcadler

Master's Theses

As the prevalence of vitamin D deficiency continues to grow, mounting evidence supporting its link with chronic disease strengthens suggesting vitamin D’s candidacy in the prevention and treatment of multiple disease states and their complications. Dietary guidelines, however, do not take sun exposure into account. The present study sought to explore the impact of sun exposure on vitamin D status (serum 25(OH)D), and identify other significant determinants of serum levels which may have the greatest effects on overall health. Participants (n = 34) were pre-menopausal women aged 18 to 50 years (mean age 39 ± 6 years), who had their …

The Association Of Diet And Physical Activity With Stroke Mortality Results From The Adventist Health Study-1, Tahereh Zamansani

Loma Linda University Electronic Theses, Dissertations & Projects

Stroke is one of the leading causes of death and disability, with major global public health implications. Stroke ranks No. 4 among all causes of death, behind heart disease, cancer, and chronic lower respiratory disease (CLRD). Stroke accounts for almost 1 of every 18 deaths in the United States. Women accounted for 60.6% of stroke deaths. Death certificate data show that the mean age at stroke death was 79.6 years; males had a younger mean age (76.3) than females.

There is still a great scientific uncertainty among researchers and epidemiologists about the magnitude of any preventive effect, mechanisms of action …

Hopscotch: Robust Multi-Agent Search, Edward C. Miles

Computer Science ETDs

The task of searching a space is critical to a wide range of diverse applications such as land mine clearing and planetary exploration. Because applications frequently require searching remote or hazardous locations, and because the task is easily divisible, it is natural to consider the use of multi-robot teams to accomplish the search task. An important topic of research in this area is the division of the task among robot agents. Interrelated with subtask assignment is failure handling, in the sense that, when an agent fails, its part of the task must then be performed by other agents. This thesis …

Knox1 Genes Regulate Lignin Deposition And Composition In Monocots And Dicots, Brad T. Townsley, Neelima R. Sinha, Julie Kang

Faculty Work

Plant secondary cell walls are deposited mostly in vascular tissues such as xylem vessels, tracheids, and fibers. These cell walls are composed of a complex matrix of compounds including cellulose, hemicellulose, and lignin. Lignin functions primarily to maintain the structural and mechanical integrity of both the transport vessel and the entire plant itself. Since lignin has been identified as a major source of biomass for biofuels, regulation of secondary cell wall biosynthesis has been a topic of much recent investigation. Biosynthesis and patterning of lignin involves many developmental and environmental cues including evolutionarily conserved transcriptional regulatory modules and hormonal signals. …

An Evaluation Of The Source Area For The Former Norges Cleaners Tetrachloroethylene Plume Near Centennial Boulevard And Vine Street, Hays, Ks, Over A 20-Year Span Using Past Data To Estimate The Plume Concentration Reduction, Adam Staab

Master's Theses or Doctor of Nursing Practice

Analyses of monitoring well data from 2001 to 2009 of a perchlorethylene (PCE) pollution plume located in Hays, Kansas were used to assess the current PCE status and to project the plume rate of decline to when remediation will cease or no longer be required. Isoconcentration maps were used to calculate an average rate of concentration reduction. Based on these calculations, I believe the PCE concentration has the potential to be below the 5 μg/L Risk-based Standards for Kansas by 2020 for the study area.

Changes In Plasma Melanocyte-Stimulating Hormone, Acth, Prolactin, Gh, Lh, Fsh, And Thyroid-Stimulating Hormone In Response To Injection Of Sulpiride, Thyrotropin-Releasing Hormone, Or Vehicle In Insulin-Sensitive And -Insensitive Mares, N. Arana Valencia, D. L. Thompson, P. B. Mitcham

Faculty Publications

Six insulin-sensitive and 6 insulin-insensitive mares were used in a replicated 3 by 3 Latin square design to determine the pituitary hormonal responses (compared with vehicle) to sulpiride and thyrotropin-releasing hormone (TRH), 2 compounds commonly used to diagnose pituitary pars intermedia dysfunction (PPID) in horses. Mares were classified as insulin sensitive or insensitive by their previous glucose responses to direct injection of human recombinant insulin. Treatment days were February 25, 2012, and March 10 and 24, 2012. Treatments were sulpiride (racemic mixture, 0.01 mg/kg BW), TRH (0.002 mg/kg BW), and vehicle (saline, 0.01 mL/kg BW) administered intravenously. Blood samples were …

Multifunctional Nanophosphors For Tissue Imaging And Drug Delivery, Hongyu Chen

All Dissertations

X-rays have been used for non-invasive high-resolution imaging of thick biological specimens since their discovery in 1895. They are widely used for structural imaging of bone, metal implants, and cavities in soft tissue. Recently, a number of new contrast methodologies have emerged which are expanding X-ray's biomedical applications to functional as well as structural imaging. However, traditional X-ray imaging provides high spatial resolution imaging through tissue but do not measure chemical concentrations. In this dissertation, we describe an X-ray excited optical luminescence (XEOL) technique which uses a scanning X-ray beam to irradiate Gd2O2S phosphors and detect the resulting visible luminescence …

Aerosol Delivery As A Method For Enhancing Remedial Application In Contaminated Vadose Zones, Richard Hall

All Dissertations

Remediation of contaminated vadose zones is often hindered by an inability to effectively distribute liquid- or solid-phase amendments. Many amendment-based approaches, such as bioremediation, chemical oxidation, and reactive barriers have been successful in saturated formations. However, these remedial approaches have seen limited application in unsaturated materials, largely because of difficulties delivering amendments.
Aerosol delivery is a promising approach for distributing amendments in contaminated vadose zones. The amendments are aerosolized, creating a cloud of micron to sub-micron-scale liquid droplets held suspended in a gas by Brownian motion. During injection into porous media, the aerosol particles are transported along with the gas …

Correlation Of Physicochemical Properties Of Chondroitin Sulfate To Its In-Vitro Absorption And Anti-Inflammatory Activity, Lahari Surapaneni

All Dissertations

The purpose of this study was to investigate if the molecular weight and degree of sulfation of chondroitin sulfate (CS) has an impact on its in vitro absorption and anti-inflammatory activity.
For absorption studies, Caco-2 cells were incubated with eight CS samples of differing molecular weights (7 kDa - 35 kDa). The amount of CS transported into the basolateral side of the Caco-2 monolayer was quantitatively determined to calculate the permeability coefficients (Peff). The permeability coefficients of the eight different CS samples across Caco-2 cell monolayers were assessed. For anti-inflammatory studies, RAW 264.7 murine macrophage cells were pre incubated with …

Highly Sensitive Fiber-Based Devices For Gene And Protein Analysis, Victor Maximov

All Dissertations

Single cell probing has found a number of applications in different areas of research. It can help us to better understand cell-to-cell interactions; it has found numerous applications in immunology, cancer research, detection of pathogenic infections and genetic abnormalities. The single cell analysis is very important in stem cells research and development of cells. The main obstacle in the single cell analysis is the small amount of analyte that a single cell could provide. Another difficulty is connected to the cell-to-cell variability inside the uniform population due to the differences of single cells in size, activity, mitotic stage, and functions. …

The Effects Of Chromium On Cellular Viability And Chromium Tolerant Gene Expression Within Synechococcus Sp. Iu 625, Richard Garrett

Theses, Dissertations and Culminating Projects

Heavy metal contamination in the environment is always a big concern. Many microorganisms have developed metal tolerant /resistant mechanisms to survive in such environment. Cyanobacteria Synechococcus sp. IU 625 (S IU 625) formerly known as Anacystis nidulans have been used an indicator for studying many EPA targeted heavy metals such as Zn+2, Cu+2, Hg+2. This microorganism has been reported to have resistant mechanisms to mercury and zinc. In this study, in silico analysis was used to determine the pANL plasmid-mediated chromium resistant genes of Synechococcus sp. IU 625. DOOR and STRING were used to determine the operons and identity potential …

Autopoiesis: Scaffolding The Reflective Practitioner Toward Employability, Sarah Bown

International Journal of Interpreter Education

Sign language interpreters confront a diversity of complex situations in their everyday work. To be able to consider and appropriately respond to such situations, interpreters need robust cognitive reflective frameworks to support them. Since 1993, the University of Wolverhampton’s BA (honors) Interpreting British Sign Language/English course has delivered undergraduate training to aspiring sign language interpreters. The end product has been high levels of “appropriate” graduate employability success, in part due to the strong correlation between what employers regard as essential and desirable in an employee, and the attributes demonstrated by the reflective practitioners created by the program. In this article, …

Biomarkers Of Fatigue: Metabolomics Profiles Predictive Of Cognitive Performance, Nicholas J. Delraso, Deirdre A. Mahle, John J. Schlager, Donald L. Harville, Scott R. Chaiken, Danelle K. Roddy, Mari Chamberlain, Paul E. Anderson, Nicholas V. Reo, Michael L. Raymer, Isaie Sibomana

Computer Science and Engineering Faculty Publications

Cognitive performance and fatigue are well known to be inversely related. Continuous and sustained actions in operational environments typically lead to reduced sleep normally required to perform optimally. These operational environments subject the warfighter to intense physical and mental exertion. Because fatigue continues to be an occupational hazard, leading to cognitive defects in performance, there has been a recognized need for real-time detection technologies that minimize fatigue-induced mishaps. I the current study, 23 subjects were subjected to 36h of sleep deprivation and cognitive psychomotor vigilance and automated neuropsychological assessment metric tests were conducted over the last 24 h of sleep …

Qualitative Narrative Research Investigating The Value Of Visual Art Education Captured Through The Stories Of High School Students Labeled At-Risk, Leah C. Peca

Art Education Projects

My personal and professional experiences in education led me to develop a unique perspective on the value of the visual arts. Existing literature about the impact of visual art education on students is written primarily from the point of view of educators and researchers. I wondered what the stories of high school students who have been labeled at-risk might reveal about their visual art experiences. As a participant-observer, I studied my own students using a postmodern approach to qualitative narrative research. I chose six students, three of whom were labeled at-risk, to share their stories and opinions about their visual …

Early Life Stress, Drug Abuse, Exercise Effects On Bdnf And Sex-Influenced Excercise Differences, Karissa Dold

Honors College Theses

In 2011, the U.S. reported 3 million child maltreatment cases, an uncomfortably high but recurring figure each year. Research shows exposure to early life stress (ELS) increases an individual’s susceptibility to substance abuse, specifically of nicotine, alcohol, and cocaine. Increased susceptibility may result from dysregulation of the HPA axis sustaining activation into adulthood after ELS. Hyperactivation of the HPA axis significantly reduces hippocampal BDNF, a neurotrophin involved in neuronal growth and plasticity. Reduced hippocampal BDNF may be a factor in substance abuse vulnerability. Additionally, research shows exercise protects hippocampal BDNF from stress induced down-regulation. To explore these relationships, this study …
