Pediatric Air Gun Shot Injury, Ubaid U. Khan, Naglaa M. Kamal, Shazia J. Mirza, Laila M. Sherief

Saudi Medical Journal

Air guns (AGs) use air or another compressed gas to propel a projectile. Different injuries may occur in children due to their body structure, which is less-resistant with thin soft tissue coverage that can be easily penetrated by an AG shot. We present 3 cases of pediatric AG shot injury. The first-case had right lumber deep tissue penetration of AG pallet without internal damage, the second-case had a complex course of pellet into the perineum, and the third-case was shot in the left shoulder. All cases were accidentally shot. The shooters were all children, and relatives of the victims. All …

Aminoglycoside-Induced Otoneurotoxicity: Analysis Of Inner Hair Cell Synaptic Plasticity Following Drug Exposure, Matthew M. Abernathy

Dissertations

Aminoglycoside antibiotics are powerful drugs for combating bacterial infections, but are limited in use due to their ototoxicity. This class of drug targets the auditory hair cells of the cochlea, causing cell death, which leads to a decline in auditory function. In spite of much research aimed at revealing a mechanism of damage, there are no co-therapies available to diminish the ototoxic liability of aminoglycosides. Existing research does show that there may be a neurodegenerative process that contributes to the observed toxicity. In an effort towards clarifying present understanding of issue, this dissertation project was conducted to characterize the neurodegenerative …

Probing The Unfolding And The Stability Of The Last Four Metal Binding Domains Of Wilson Disease Protein Using Circular Dichroism And Novel Spectroscopic Techniques, Ibtesam Yaseen Alja’Afreh

Dissertations

Wilson disease protein is a copper-transporting P_1B type ATPase. It has large N-terminal copper binding domain which is composed of six homologous sub-domains. Each of these six domains is ~72 residues and connected to one another by linking regions of various lengths. They all possess similar ferrodoxin fold, and metal-binding motif, MXCXXC.

The need of having six metal binding domains and the manner in which they are communicating with each other is not well understood. To better understand how the last four metal binding domains function, I pursued a detailed biophysical characterization of these domains. Using molecular biology I …

The Relationship Between Racial Ambiguity And Self-Concept In Multiracial Lndividuals, James R. Jobe

Dissertations

The present study examined the relationship between racial ambiguity and self-concept in multiracial individuals. Research as to the experiences of multiracial people is limited both in frequency and in scope. As multiracial individuals continue to grow in number, understanding their unique experiences will become more important to social scientists (e.g., psychologists, anthropologists, sociologists) across disciplines. The current study examined two hypotheses and explored a series of additional relationships. The theoretical framework that was utilized for this study was Symbolic Interaction Theory. This theory provided an effective way to understand how people use and make meaning of their surrounding social contexts …

An Examination Of How Feminist Perspectives And Generational Differences Lnfluence The Leadership Practices Of Women Administrators In Higher Education, Marlene Kowalski-Braun

Dissertations

This study explored how feminist perspectives and generational differences influence the leadership practice of women administrators in higher education, specifically, how they lead and create institutional change. It examined the experiences of seven women who identified as feminists, who were part of Generation X, and who were at the mid-level, aspiring to senior-level, or in senior-level positions.

Phenomenology was the qualitative methodology used in this study to uncover how these women made meaning of their feminist and generational identities. The approach was grounded in feminist methodology and utilized feminist standpoint theory to legitimize women as “knowers.” It drew on a …

Ultrafast Interfacial Electron Transfer Across Molecule-Tio2 Nanocomposites: Towards Solar Cells And Two Photon Absorption, Edwin Mghanga

Dissertations

Interfacial charge transfer (ICT) across the molecule-TiO2 nanoparticle interface has gained enormous research attention for applications in dye sensitized solar cells (DSSC), photo-catalysis, water splitting and nonlinear optics. DSSCs are promising clean alternative energy sources. However, current DSSCs suffer from lower efficiencies and higher cost. Better understanding of the ICT processes in DSSCs can help solve these problems. We have used two strategies to understand ICT in the context of DSSCs. Firstly, we used a computationally validated anchor group, acetylacetonate (acac) to bind molecules to the semiconductor surface and facilitate charge separation. Secondly, we used natural dye sensitizers, …

Math, Class, And Katrina Aftermath: The Impact Of Experiences Teaching Mathematics To Low-Income Middle School Students On Middle-Income Teachers’ Pedagogical Strategies, Susan J. Ikenberry

LSU New Orleans Theses and Dissertations

Despite a century of educational reforms, no matter how achievement is measured, learning and opportunity gaps can still be predicted by race and socioeconomic status. Teachers and schools are blamed for functioning to reproduce social inequality. This study investigated teacher agency and transformative potentials. It considered how teachers modified their pedagogical practices when teaching low-income and high-poverty students. In order to capture teacher beliefs and logic, a qualitative approach was used involving in-depth interviews of a small number of participants.

The research used the context of the dislocation of students from high-poverty Orleans Parish schools in the year following Hurricane …

You're A Good Man, Charlie Brown: An Analysis Of Compassion, Friendship, And Overcoming Obstacles, Jessamyn L. Miller

Master's Theses

Since the late 1960s many things have changed. With the inception of the Internet, much of the world has gone viral––including newspapers. Children rarely find the same joy their parents found in a nostalgic printed Sunday morning comic strip. In addition, societal tragedies have increased with almost daily occurrences highlighted on the news. With an influx of recent tragedies too close to home, this thesis examines arts advocacy facts, anti-bulling campaigns, and the themes of friendship, compassion, and overcoming obstacles within a production of Clark M. Gesner’s musical You’re a Good Man, Charlie Brown [Revised]. Charles M. Schulz’s classic characters …

In the light of Latin American testimonio theoretical approach, which includes questions such as the cultural production under the intensification of neoliberal policies and the inquiry of the complicity between literary practices and the state as formulated by Rama in The Lettered City, this study examines the novel Capão Pecado, representative work of the writer and cultural activist Ferréz, and the potential relation to the formal elements of the former criticism. By thinking alongside John Beverley's case study on I, Rigoberta Menchú's testimonial narrative and Ferréz, prominent author of the contemporary production of literatura marginal and representative of the expression …

Does Who We Are Influence What We Say? The Impact Of Organizational Identity On Responses To Ethical Issues, Amy J. Guerber

Graduate Theses and Dissertations

Business organizations frequently face ethical issues which may lead stakeholders to question the competence or integrity of organizational actors. In such cases, the way the organization communicates with its stakeholders can play a critical role in preserving or restoring organizational reputation, financial performance, and trust. Thus, understanding factors that influence organizational communication in the wake of ethical issues is important. Previous research has focused on the impact of situational characteristics on organizational responses and stakeholder reactions to those responses but has not explored the role that organizational characteristics play in shaping firms' responses to ethical issues.

The current study seeks …

Honors Theses

This study investigates the relationship between television and social perceptions. It uses the television shows Will&Grace, The L Word, Queer as Folk, and Modern Family for rhetorical analysis. Then, it uses the information gained from the analysis to hypothesize how and why these television shows both reflect and affect social perceptions of homosexuality.

Effects Of A Nutrition Education Intervention On Inner City Children, Stephanie P. Windle

Honors Theses

This paper focuses on nutrition education research conducted between February and April 2014. The researcher’s goal was to determine the effectiveness of a nutrition education intervention on low-income children. The USDA and Academy of Nutrition and Dietetics provided most of the research used to create the intervention. The definition of “healthy” used for this study was defined by the USDA (2014) as “whole foods such as fruits, vegetables, whole grains, fat free or low-fat dairy, and lean meats that are perishable (fresh, refrigerated, or frozen) or canned as well as nutrient-dense foods and beverages encouraged by the 2010 Dietary Guidelines …

The Eu's Cookie Cutter, But Not The Eu's Cookie, Sylvia Zdunek

Honors Theses

The members of the European Union have never had a common identity that has united them together beyond their geographical definition of "Europe." Since the beginning of the European Union and the introduction of the Euro, the decision makers of the Union have been pushing for a collective European identity. The need for this identity comes from the belief that in order for the Union to be economically sound, it needs an underlying homogenous culture. A unity in identity, values, and ideals is stronger than a unity based solely on a common currency as it lacks personal characteristics that people …

"I Wasn't Born A Boy – I Was Born A Baby": Best Practices Versus Accepted Practices In News Coverage Of The Transgender Community, Anna Hornell

Journalism

As transgender people and issues have gained prominence in American media over the past few years, more and more journalists find themselves covering a small and marginalized community that they may not have any previous experience with. Using standards set by LGBT media watchdog GLAAD, this study aimed to examine how the prevalence of problematic journalistic practices in covering the transgender community has (or has not) changed in recent years. A content analysis of 1,019 U.S. newspaper articles from 2009 and 2014 revealed some significant changes: almost all GLAAD-identified problematic practices that were studied appeared less commonly in 2014, although …

Beware: Teachers Who Blog, Charles J. Russo

Educational Leadership Faculty Publications

A recent case from Pennsylvania, Munroe v. Central Bucks School District (2014), raises fresh questions about the free speech and expression rights of public school teachers as they use the Internet. In Munroe, when a board terminated a high school teacher’s employment for making controversial postings about her students and colleagues on her personal blog—postings that proved disruptive—a federal trial court rejected the educator’s claim that she was dismissed in retaliation for exercising her right to free speech.

Before reviewing the facts and judicial opinion in Munroe, it is worth noting that blogs (a term coined in the late 1990s …

Assessing Pragmatic Language In Autism Spectrum Disorder: The Yale In Vivo Pragmatic Protocol, Elizabeth Schoen Simmons, Rhea Paul, Fred Volkmar

Communication Disorders Faculty Publications

Purpose: This study compared pragmatic language in youths (9–17 years) with autism spectrum disorder (ASD) and those with typical development (TD) on the Yale in vivo Pragmatic Protocol (YiPP), a semistructured, dynamic conversational assessment. Method: Participants (n = 118) were divided into groups based on age and diagnosis. Each completed the YiPP, which included 4 pragmatic domains (discourse management, communicative functions, conversational repair, presupposition). The participant’s response to each probe was scored correct or incorrect; incorrect scores elicited cues from the examiner, and level of cue required for a correction was also scored. Results: The YiPP showed high reliability and …

Competitive Evaluation Of Data Mining Algorithms For Use In Cassification Of Leukocyte Subtypes With Raman Microspectroscopy, Adrian Maguire, I. Vega-Carrascal, Jane Bryant, Lisa White, Orla Howe, Fiona Lyng, Aidan Meade

Articles

Raman microspectroscopy has been investigated for some time for use in label-free cell sorting devices. These approaches require coupling of the Raman spectrometer to complex data mining algorithms for identification of cellular subtypes such as the leukocyte subpopulations of lymphocytes and monocytes. In this study, three distinct multivariate classification approaches, (PCA-LDA, SVMs and Random Forests) are developed and tested on their ability to classify the cellular subtype in extracted peripheral blood mononuclear cells (T-cell lymphocytes from myeloid cells), and are evaluated in terms of their respective classification performance. A strategy for optimisation of each of the classification algorithm is presented …

Pathogenic Role Of Acrolein In Alcoholic Liver Disease., Wei-Yang (Jeremy) Chen

Electronic Theses and Dissertations

Alcohol is the most socially accepted addictive drug, and it can cause alcoholic liver disease (ALD), which is a major cause of morbidity and mortality in the United States and worldwide. Animal and human studies demonstrate that chronic alcohol consumption causes a pro-oxidant environment in the liver and increases hepatic lipid peroxidation and the accumulation of by-products such as acrolein and 4-hydroxynonenal. Acrolein is the most reactive and toxic aldehyde generated through lipid peroxidation. Also, acrolein is a major component of cigarette smoke, and there is increasing evidence that smoking negatively impacts the incidence, severity, and clinical course of chronic …

Pedagogy : Reconsiderations And Reorientations., John Vance

Electronic Theses and Dissertations

This dissertation is a critical intervention into the question of student agency. An interdisciplinary project that draws upon philosophy and linguistics, it reviews four major tendencies that have animated composition pedagogy over the last several decades— process theory, social-constructivism, procedural rhetoric, and trans-lingual pedagogies— and identifies some of the key tensions that both motivate and problematize these approaches. First, it examines the debate between Peter Elbow and David Bartholomae, and the interplay between teachers’ authority and student agency. Second, it explores the imbrications between representation and materiality in social constructivism. Third, it uses Alain Badiou’s Being and Event to analyze …

Novel Analytical Tools For Studies In Molecular Assemblies : I. Electro-Active Single-Mode Integrated Optical Waveguides ; Ii. Coupled Plasmon Waveguide Resonances., Xue Han

Electronic Theses and Dissertations

Two optical analytical tools were developed for studying molecular assemblies at solid/liquid interfaces. Electro-active single-mode integrated optical waveguide (EA-SM-IOW) technology was developed as a platform for spectroelectrochemical investigations on redox adsorbates at the sub-monolayer level. With an optimized ultra-thin indium tin oxide film combined with a single-mode integrated optical waveguide, for the first time, a more than 14,000 times higher sensitivity (compared to conventional potential-modulated transmittance) was achieved. From optical signals, this technique was able to reconstruct electrochemical information of redox adsorbates, including the formal potential and the electron transfer rate. A few major advantages were achieved with the developed …

Lunasin Reduces The Melanoma Stem Cell Population In Vitro And Inhibits Tumor Proliferation In Vivo., Christopher Paul Shidal

Electronic Theses and Dissertations

Lunasin is a 44 amino acid peptide derived from the soybean seed that has been shown to have cancer chemopreventive and chemotherapeutic properties. In this study, we investigated the potential utility of lunasin as a chemotherapeutic in a melanoma model. Initial studies showed that lunasin has little activity against established melanoma cell lines in vitro using adherent culture methods; however, lunasin’s in vitro activity was significantly higher in non-adherent colony-forming assays in soft agar and oncosphere assays. These results led us to investigate whether lunasin selectively affects cancer initiating cells (CIC) that are known to be present in these melanoma …

Modulation Of The Ovarian Cancer Humoral Response By Tumor-Derived Exosomes., Carolyn Denise Roberson

Electronic Theses and Dissertations

The pathogenesis of epithelial ovarian cancer is complicated by its diagnosis during the latter stages of the disease resulting from lack of symptoms or from presence of symptoms that mimic other conditions. Because of the often fatal prognosis by the time of actual detection, efforts are being made to better understand the host immune response to ovarian cancer. In this study, the contributions of the humoral immune response were investigated by focusing on the role of tumor-derived exosomes and their ability to modulate humoral immune responses. First, ovarian cancer patient-derived free circulating antibodies were investigated for immunoreactivity to patient antigen. …

Split-Step Approach To Electromagnetic Propagation Through Atmospheric Turbulence Using The Modified Von Karman Spectrum And Planar Apertures, Monish Ranjan Chatterjee, Fathi H.A. Mohamed

Electrical and Computer Engineering Faculty Publications

The impact of atmospheric phase turbulence on Gaussian beam propagation along propagation paths of varying lengths is examined using multiple random phase screens. The work is motivated by research involving generation and encryption of acousto-optic chaos, and the interest in examining propagation of such chaotic waves through atmospheric turbulence. A phase screen technique is used to simulate perturbations to the refractive index of the medium through the propagation path. A power spectral density based on the modified von Karman spectrum model for turbulence is used to describe the random phase behavior of the medium.

In recent work, results for the …

The Investigation Of Surplus Of Energy And Signal Propagation At Time-Domain Waveguide Modes, Özlem Işık, Zeynep F. Koçak, Emre Eroğlu

Applications and Applied Mathematics: An International Journal (AAM)

Classical waveguide theory has been developed bearing on Bernoulli’s product method which results in separation of space and time variables in Maxwell’s equations. The time-harmonic waveguide modes have been stated mathematically for transmitting signals along the waveguides. As a starting point, present studies on transverse-electric (TE) and transverse-magnetic (TM) waveguide modes with previous results are taken and exhibited in an advanced form. They have been obtained within the framework of an evolutionary approach to solve Maxwell’s equations with time derivative. As a result every modal field is obtained in the form of a product of vector functions of transverse coordinates …

Investigation Into The Early Events Of Epithelial Wound Healing And Hpv16 Infection, Michael P. Kivitz

Biomedical Sciences ETDs

HPV16 infection evidently occurs within wounded epithelial tissue, but the cellular and molecular events that culminate in infection establishment remain poorly understood. While HPV is exposed to a multitude of cells in the wound environment, only hyperproliferative keratinocytes are believed to support productive infection. Keratinocytes acquire mobility during wound repair by undergoing prominent phenotypic alterations through an epithelial-to-mesenchymal transition (EMT). In this study, cell- and tissue-based models were employed to characterize HPV infection during epithelial wound healing, using both physical injury and growth factor treatment to induce keratinocyte migration. In a tissue-based model of wounding and infection using NIKS-derived organotypic …
