Cytotoxicity And Cellular Response To Alpha, Beta-Unsaturated Aldehydes : Role Of Aldehyde Dehydrogenases., Ngome Llewellyn Makia

Electronic Theses and Dissertations

The lipid aldehydes, 4-hydroxy-2-nonenal (4-HNE) and propene-2-al (acrolein) are reactive a,ß-unsaturated aldehydes generated during the peroxidation of lipids and are implicated in the pathogenesis of several oxidative-stress mediated diseases, including steatohepatitis and cancer. We established that mouse liver aldehyde dehydrogenase 1 al (Aldhlal) efficiently metabolizes lipid aldehydes and protects a liver-derived cell line from the toxic effects of these aldehydes. Thus, mechanisms to induce the expression of Aldhlal might be a useful rationale for preventing oxidative stress-induced pathologies. We investigate whether well-known electrophiles, such as BHA or acrolein modulate the expression of Aldhlal and elucidate the signaling pathway involved. Microarray …

Exploring The Scholar-Practitioner Gap In Personnel Selection Assessments : An Analysis Of Scholarly Versus Practitioner Literature., Whitney L. Martin 1977-

Electronic Theses and Dissertations

Research suggests that a gap exists between scholarly findings and practitioner knowledge, beliefs, and practices in the Human Resource field, particularly in the area of employee selection (Deadrick & Gibson, 2007; Rynes, Giluk, & Brown, 2007). This study seeks to explore this gap relative to self-report selection assessments by examining practitioner-oriented versus scholarly literature. Articles published between January 2006 and September 2011 from two scholarly sources (Journal of Applied Psychology and Personnel Psychology) and two practitioner sources (HR Magazine and HR Executive) were reviewed, and 49 articles were selected for inclusion in analysis. Qualitative content analysis was used to analyze …

Acquisition Of Mathematical Vocabulary Using Constant Time Delay With Individuals With Moderate And Severe Disabilities., Connie Elaine Morrison 1974-

Electronic Theses and Dissertations

Constant Time Delay (CST) has been used extensively as a procedure to teach children with disabilities a variety of skills. There is a preponderance of evidence that this instructional strategy is a highly effective (Handen & Zane, 1987; Koscinski & Gast, 1993; & Schuster, Stevens, & Doak, 1990). However, there appears to be a lack of research regarding the use of CTD with children with moderate and/or severe disabilities in learning core content vocabulary. Therefore, the primary purpose of this study was to determine if students with moderate and severe disabilities could acquire core mathematical vocabulary content through the use …

A Survey Study Comparing Adult Orthodontic Patient Quality Of Life Between Invisalign And Fixed Appliances., Keith Christopher Nicholson

Electronic Theses and Dissertations

We aimed to examine differences in treatment impacts and quality of life between adult orthodontic patients with Invisalign and fixed appliances. Adults represent a burgeoning branch of orthodontics yet many prospective patients have been reluctant to pursue orthodontics due to concerns with treatment. It was hypothesized that removable aligners would be better tolerated by adult patients. Sixty-three adult patients (forty Invisalign, twenty-three fixed appliances) were recruited from private practice. The treatment groups were largely comparable although the braces group reported more frequent unplanned appointments and use of auxiliaries. The Invisalign group experienced less negative impacts and these differences were generally …

Rational Design, Synthesis And Characterization Of Amide Functionalized Pyridine And Benzimidazole Transition Metal Complexes., Samuel S. K. Asem

Electronic Theses and Dissertations

This study expands our efforts to make a new class of Pt (II) compounds analogous to cisplatin and its derivatives using sterically hindered ligands. Pt compounds in this series have been synthesized using specially designed pyridine and benzimidazole ligands. These heterocycles, amide functionalized at position 2 with aryl and alkyl pendants, rapidly change their mode of coordination depending on the pH of the medium. These ligands, synthesized using condensation chemistry, also coordinate to Co(II), Ni(H), Cu(lI), and Zn(1I) generally as anionic bis-chelates through the benzimidazole nitrogen and the carbonyl oxygen, creating a four-coordinate complex with the exception of an unusual …

Quidam Homo Est Asinus : The Originality And Influence Of Peter Abelard Upon Medieval Thought., Timothy Ernst 1982-

Electronic Theses and Dissertations

Historians and philosophers alike remember Peter Abelard as the most brilliant, original, and influential philosopher of the twelfth century. Much ofthis reputation stems not from Abelard's intellectual contributions but due to Abelard's scandalous personal life and the nonexistence of documents of Abelard's contemporary philosophers. Though brilliant, Abelard exerted little influence through his ideas. Unlike a modem professor who changes the paradigms of his discipline with innovative theses, Abelard was a skilled teacher who sought to teach students the skills they required to advance their careers within a reformed Catholic Church, which was newly interested in logic, philosophy, and theology. Seen …

Methods. Twenty-four patients with 1 site of 2: 3 mm Miller Class I or II recession were treated and followed for 4 months. Twelve patients received a coronally positioned tunnel plus ADM and were considered the test group. The positive control group consisted of 12 patients treated with a coronally positioned tunnel technique plus connective tissue graft and were considered the control group. …

Analyzing Common Algebra-Related Misconceptions And Errors Of Middle School Students., Sarah B. Bush

Electronic Theses and Dissertations

The purpose of this study was to examine common algebra-related misconceptions and errors of middle school students. In recent years, success in Algebra I is often considered the mathematics gateway to graduation from high school and success beyond. Therefore, preparation for algebra in the middle grades is essential to student success in Algebra I and high school. This study examines the following research question: What common algebra-related misconceptions and errors exist among students in grades six and eight as identified on student responses on an annual statewide standardized assessment? In this study, qualitative document analysis of existing data was used …

Regulation Of Morphogenesis By Ammonium Transporters In Ustilgo Maydis., Jinny A. Paul

Electronic Theses and Dissertations

Many species of fungi undergo a dimorphic transition to switch from a unicellular yeast-like growth form to a filamentous growth form. Ustilago maydis undergoes such a transition, in response to successful mating events and subsequent host cues, to form a filamentous pathogenic form. U maydis also undergoes haploid filamentous growth in response to several environmental cues including, but not limited to nutrient limitation, pH, lipids, among others. Ammonium transporter proteins (Amts) play an essential role in controlling the dimorphic transition in response to nutrient limitation, specifically nitrogen in the form of ammonium. I demonstrate a role for the U maydis …

The Cost-Effectiveness Of The Kentucky Pilot Project Of Allowing Primary Pci At Hospitals Without Onsite Cabg Capabilities., Pedro Ramos

Electronic Theses and Dissertations

A myocardial infarction (MI) occurs when blood supply to the heart is cut off by a blockage in one of the coronary arteries. Most hospitals treat a patient with thrombolysis or a percutaneous coronary intervention (PC I). The latter has been established as the preferred revascularization method. However, the American College of Cardiologists and the American Heart Association strongly recommend that a hospital performing PCI must also have coronary artery bypass graft capabilities (CABG). By following these recommendations, the state of Kentucky has limited the number of hospitals allowed to perform PCI and thereby limiting access to such a life-saving …

That Terrifying Center : Poetry, Language, And Embodied Subjectivities., Yalonda J. D. Green 1980-

Electronic Theses and Dissertations

That Terrifying Center is a creative and philosophical experiment in the transmission of corporeal experiences and socio-cultural knowledge through poetry. I am bringing together the seemingly disparate threads of my studies into one creative-theoretical project: a collection of original poems exploring the development of multiple subjectivities, the terror of self-examination, and the scrutiny of memory; it is also a collection of poems that bear witness, that simply tell stories. These are poems that talk about what it's like to live in a body; they ask questions and translate answers related to becoming woman, demystifying fear, investigating genealogies of pain, and …

Food Stamps And Dependency: Disentangling The Short-Term And Long-Term Economic Effects Of Food Stamp Receipt And Low Income For Young Mothers, Thomas P. Vartanian, Linda Houser, Joseph Harkness

The Journal of Sociology & Social Welfare

The Food Stamp Program (FSP) remains one of the most widely used of all U.S. social "safety net" programs. While a substantial body of research has developed around the primary goals of the program- improving food access, nutrition, and health among lowincome families-less attention has been paid to the broader goals of hardship and poverty reduction. Using 38 years of data from the Panel Study of Income Dynamics, we examine several immediate and longer-term economic outcomes of early adult FSP participation for a sample of3,848 young mothers. While FSP participation is associated with some negative outcomes in the immediate future …

A Randomized Trial To Evaluate The Course Of Effects Of A Program To Prevent Adolescent Depressive Symptoms Over 12 Months., Patrick Pössel, Jill L. Adelson, Martin Hautzinger

Faculty and Staff Scholarship

Although few prevention studies have been designed to investigate the course of prevention effects over time, it seems that the effects on depressive symptoms increase from post-intervention to 6-month follow-up but then decrease with longer lags to follow-up. Furthermore, previous prevention studies have found differential intervention effects for boys and girls without testing possible explanations for this effect. The present randomized control group study with 301 8th-grade students examined the effects of a depression prevention program from baseline until 12-month follow-up. As expected, while positive intervention effects were found on girls’ depressive symptoms, no such effects were found on boys’ …

Disharmony And Matchless: Interpersonal Deception Theory In Online Dating, Lyndsey Wagner

Masters Theses

In recent years, computer-media dated communication has not only become extremely popular but has also begun to hold an important function in daily social interactions. This qualitative study investigates the communication phenomena of deception as it occurs in the online dating environment. The research study focused on four questions: (1) About what characteristics are online daters deceptive? (2) What motivation do online daters have for their deception of others in the online dating environment? (3) What perceptions do online daters have about other daters' deceit towards them in the online dating environment? (4) How does deception affect the romantic relationships …

Defending Tertullian's Orthodoxy: A Study On Third Century Christianity, Kevin Gift

Masters Theses

Scholars have attempted to place Tertullian into two or three distinct schools of thought. Some, such as Pope Benedict XVI, state that Tertullian turned his back on the church. Others, like Andrew McGowan, posit a more complex timeline. McGowan claims Tertullian left the church only to return at a later date. The reason for such speculation was Tertullian's interest in the Montanist, a second to third century heretical group. The goal of this study is to provide sufficient evidence that Tertullian never made the complete move to Montanism and never separated form the church of Carthage. A careful analysis of …

Identifying Struggling Readers In Middle School With Orf, Maze And Prior Year Assessment Data, Jennifer R. Allison, Evelyn S. Johnson

Early and Special Education Faculty Publications and Presentations

Response to Intervention (RTI) is a framework with the primary purpose of early identification and prevention of learning problems. Screening procedures identify students in need of targeted intervention, but current screening research is limited to the elementary grades. This study explored the use of screening measures: prior year assessment data, oral reading fluency (ORF), and maze, to predict performance on Georgia’s Criterion-Referenced Competency Test (CRCT-8) for 236 eighth grade students from one district in Georgia. Logistic regression analyses compared the accuracy of the predictor variables. Overall classification accuracy was 96.6% for ORF and maze and 97.1% for CRCT-7; however, this …

Office Hour Scheduling Tool, Tyler Dunlap

Industrial Engineering Undergraduate Honors Theses

When an instructor (with or without student input) specifies her office hours for the semester, the informal process used often results in students experiencing conflicts with other lectures, labs, drills, or office hours. The result of this conflict is the student either scheduling individual meetings with teachers outside of their office hours or students missing the opportunity to get assistance from the instructor all together. Either outcome is undesirable, as it either takes additional faculty time from their other responsibilities or jeopardizes the performance of a student in their classes. One valid approach to solving this problem is through the …

Chernoff Dimensionality Reduction-Where Fisher Meets Fkt, Jing Peng, Guna Seetharaman, Wei Fan, Stefan Robila, Aparna Varde

Department of Computer Science Faculty Scholarship and Creative Works

Well known linear discriminant analysis (LDA) based on the Fisher criterion is incapable of dealing with heteroscedasticity in data. However, in many practical applications we often encounter heteroscedastic data, i.e., within-class scatter matrices can not be expected to be equal. A technique based on the Chernoff criterion for linear dimensionality reduction has been proposed recently. The technique extends well-known Fisher's LDA and is capable of exploiting information about heteroscedasticity in the data. While the Chernoff criterion has been shown to outperform the Fisher's, a clear understanding of its exact behavior is lacking. In addition, the criterion, as introduced, is rather …

When Is A Difference Really Different? Learners' Discrimination Of Linguistic Contrasts In American Sign Language, Joseph Bochner, Karen Christie, Peter Hauser

Articles

Learners’ ability to recognize linguistic contrasts in American Sign Language (ASL)was investigated using a paired-comparison discrimination task. Minimal pairs containing contrasts in five linguistic categories (i.e., the formational parameters of movement, handshape, orientation, and location in ASL phonology, and a category comprised of contrasts in complex morphology) were presented in sentence contexts to a sample of 127 hearing learners at beginning and intermediate levels of proficiency and 10 Deaf native signers. Participants’ responses were analyzed to determine the relative difficulty of the linguistic categories and the effect of proficiency level on performance. The results indicated that movement contrasts were the …

Rebel Without A Clause: The Irrelevance Of Article Vi To Constitutional Supremacy, Gary Lawson

Michigan Law Review First Impressions

With Stare Decisis and Constitutional Text, Jonathan Mitchell has produced what I think is the most interesting and creative textual defense (or at least partial defense) to date of the use of horizontal precedent in federal constitutional cases. Mitchell's careful analysis of the Supremacy Clause is fascinating and instructive, and he does an impeccable job of drawing out the implications of his premise that the Supremacy Clause prescribes only a very limited choice-of-law rule-a rule that does not, by its own terms, specifically elevate the Constitution above federal statutes and treaties. His innovative and intriguing framework yields four distinct conclusions …

The Life That Chose Us: Educators With Tourette Syndrome, Jennifer Kristen Stenger

Dissertations

The purpose of this phenomenological study was to explore how having Tourette syndrome has shaped educators’ relationships in their personal and professional experiences. I completed a series of three in-depth interviews with seven educators in K-12 public schools who self-identify as an educator with Tourette syndrome. I began with a background of the participants’ experiences related to having Tourette syndrome. From there, I discussed participants’ experiences in regard to attaining and retaining employment. My guiding research questions were how having Tourette syndrome shapes relationships with administrators, colleagues, and students and their parents. Also, I asked how Tourette syndrome has shaped …

A Measure Of Self-Efficacy Among Agency Directors To Offer Nutrition Education To Lowcountry Food Bank Clients, Lucie Maguire

All Theses

In 2005, the Lowcountry Food Bank (LCFB) in Charleston, SC, launched an initiative to provide nutrition education to clients that seek food assistance. The agency directors of the 332 member agencies of the LCFB are in direct contact with clients, therefore they could provide nutrition education rather than the LCFB staff alone. As such, the self-efficacy of agency directors to deliver nutrition education must be measured. The objective of this project was to measure the self-efficacy of agency directors of the LCFB. A 17-item instrument measuring self-efficacy was developed, including ten validated items from the General Self-Efficacy Scale and an …

'The Purpose Of Poetry Is To Seem As Lifelike As Possible ...': Communicating The Alive Through Contemporary Poet Chelsey Minnis's Supplemental Language, Lindsay Niedringhaus

All Theses

Contemporary poet Chelsey Minnis has a style that is unlike any other poet of today. Throughout all three of Minnis‘s collections, the speaker is unpredictable in her tone, content, and approach, appearing quite random and flippant. Furthermore, Minnis‘s distinctive use of ellipses and ideograms also separate her poetry from any of that of her contemporaries, as they take such a prominent role within her poems, refusing to be ignored. When first reading a Minnis poem, many do not know how to even begin to analyze it, as the poetry does not adhere to any traditional codes, and no rules exist …

Product And Process Based Assembly Time Estimation In Engineering Design, Michael Miller

All Theses

This thesis presents the research and development of two assembly time estimation techniques for the automotive industry. Both of these techniques are capable of being implemented early in the product life-cycle of a vehicle and require information available in this phase. Currently, assembly time estimation is performed after production has begun and is a tedious manual process requiring hours of motion-time method studies for each assembly activity. The techniques proposed in this thesis can both be performed prior to the start of production and are capable of being performed automatically after the initial mapping.
The first assembly time estimation technique …

A Method For Representing Contextualized Information (Merci) To Improve Situational Awareness Among Electronic Message Brokering System Dashboard Users, Arunkumar Srinivasan

Dissertations and Theses (Open Access)

Electronic health information brokering systems are of interest to public health informatics because they emphasize how data can be effectively shared and utilized across healthcare institutions and among providers so as to improve the quality of care, increase efficiency, and reduce costs (Lumpkin, 2002). In the domain of public health (PH) specifically, where complete and timely reporting of data is critical for all epidemiological and disease surveillance activities (Langmuir, 1976), it is imperative to ensure proper functioning of the electronic information exchange infrastructure. Receiving multiple types of data, in various formats from numerous sources, and triaging them to the appropriate …

Ckmeans.1d.Dp: Optimal K-Means Clustering In One Dimension By Dynamic Programming, Haizhou Wang, Mingzhou Song

The R Journal

The heuristic k-means algorithm, widely used for cluster analysis, does not guarantee optimality. We developed a dynamic programming algorithm for optimal one-dimensional clustering. The algorithm is implemented as an R package called Ckmeans.1d.dp. We demonstrate its ad vantage in optimality and runtime over the standard iterative k-means algorithm.
