Samoan Speech Audiometry: Developing Word Recognition Materials For Native Speakers Of Samoan, Emma Lilian Kruger

Theses and Dissertations

Hearing can be evaluated through the presentation of tones or speech. Speech audiometry determines an individual's speech recognition threshold and word recognition score. Traditionally these materials were developed using familiar, frequently used, monosyllabic words. Currently, there are various types of word recognition materials including those which use word lists, short half-lists, and materials which use sentences level stimuli with competing noise. Word recognition materials were first developed in Standard American English; today, materials are now readily available in many other languages. When possible, word recognition materials are developed digitally to standardize their presentation. Currently, no recorded word recognition materials are …

Role Of Sabp2 In Systemic Acquired Resistance Induced By Acibenzolar-S-Methyl In Plants., Diwaker Tripathi

Electronic Theses and Dissertations

Plants have evolved an efficient mechanism to defend themselves against pathogens. Many biotic and abiotic agents have been shown to induce defense mechanism in plants. Acibenzolar-S-Methyl (ASM) is a commercially available chemical inducer of local and systemic resistance (SAR) response in plants. ASM functioning at molecular level is mostly unclear. This research was designed to investigate the mechanism of ASM action in plants. It was hypothesized that SABP2, a plant protein, plays an important role in ASM-mediated defense signaling. Biochemical studies were performed to test the interaction between SABP2 and ASM. Transgenic SABP2-silenced tobacco plants were used to determine the …

Non-Classical Symmetry Solutions To The Fitzhugh Nagumo Equation., Arash Mehraban

Electronic Theses and Dissertations

In Reaction-Diffusion systems, some parameters can influence the behavior of other parameters in that system. Thus reaction diffusion equations are often used to model the behavior of biological phenomena. The Fitzhugh Nagumo partial differential equation is a reaction diffusion equation that arises both in population genetics and in modeling the transmission of action potentials in the nervous system. In this paper we are interested in finding solutions to this equation. Using Lie groups in particular, we would like to find symmetries of the Fitzhugh Nagumo equation that reduce this non-linear PDE to an Ordinary Differential Equation. In order to accomplish …

Unfiltered?: A Content Analysis Of Pro Athletes' "Twitter" Use., Justin A. Shockley

Electronic Theses and Dissertations

As new media grow, so do the users who navigate the virtual world. People and organizations are forced to adapt in order to stay relevant in a technologically driven marketplace. The sports world has been changed drastically because of new media. Athletes no longer communicate with the general public solely through traditional media outlets such as newspapers. Social networking sites such as Twitterallow athletes to directly communicate with mass audiences. This direct communication raises several questions with regard to dynamics of communication and uses of Internet portals. A content analysis examined professional athletes' "Twitter" posts to help …

The Analysis Of Palaeobotanical Remains From Native American Sites In The Tennessee Region Of The Upper Cumberland Plateau., Chase W. Beck

Electronic Theses and Dissertations

Sediment samples were collected from 3 rock shelter sites and one natural pond on the Upper Cumberland Plateau. Samples were processed to quantitatively and qualitatively evaluate pollen and charcoal abundance as well as other palaeobotanicals. The analysis was to determine when prehistoric Native Americans began controlled burns to enhance resources acquisition. Samples were also analyzed for the presence of pollen to determine vegetation changes that may accompany the use of controlled burns and to determine the onset of horticulture. The Upper Cumberland Plateau is often considered a marginal area used only seasonally by Native Americans; however, management practices may have …

Synthesis Of A Water Soluble Resveratrol Derivative As A Potential Anti-Cancer Drug., Augustine Essel

Electronic Theses and Dissertations

Research on development of water soluble anti-cancer drugs is one of the great challenges of modern medicinal chemistry. Resveratrol (Res) is one of the many phytoalexins producing stilbenoids present in several medicinal plants, grape skin, peanuts, and red wine. It has been found to exhibit anti-cancer, anti-inflammatory, and anti-oxidant properties. Water solubility and bioavailability are some of the setbacks of this interesting compound. In view of this, effort has been made to synthesize amino acid derivative of resveratrol to improve its bioavailability and solubility in water. Methyl 4-{-[(1E)-2-(3, 5-dihydroxyphenyl)-ethenyl] - phenoxy} butyrate (7), a novel ester intermediate, has been synthesized …

Isolation Of A Siderophore Produced By Methicillin-Resistant Staphylococcus Aureus Strain H372., Rachel Elizabeth Presswood

Electronic Theses and Dissertations

Iron is necessary for many cellular processes such as the electron transport chain and gene regulation. However, most iron on earth is found in insoluble iron-hydroxide complexes. In addition, iron is tightly sequestered in the human body by proteins such as transferrin, making it unavailable for pathogens. In order to overcome these limitations bacteria have evolved siderophores. Siderophores are low molecular weight compounds that bind ferric iron with a high affinity. Staphylococcus aureus is an important human pathogen that is known to produce at least four siderophores, and these siderophores contribute to its virulence. S. aureus strain H372 was found …

Potential Biases In Estimating The Rate Parameter Of Sigmoid Growth Functions, Robert Ricklefs, Suzanne Austin, Tara Robinson, W. Robinson

Biology Department Faculty Works

1. We compare biases in estimates of the rate constant of the logistic and Gompertz functions applied to avian growth using three methods of parameter estimation. The methods differ in how the asymptote is determined, and consist of either floating asymptotes estimated from the full data (floating A) or data truncated at 70% of the adult mass (70%A), or fixing the asymptote at the adult mass (fixed A).2. First, using data for two passerine species exhibiting different growth patterns, we truncated mass measurements at different ages to explore how each method of growth rate estimation responded to simulated differences in …

Adam10 Is A Critical Regulator Of B Cell Development, Antibody Production, And Myeloid-Derived Suppressor Cell Expansion: Effects Of B Cell-Specific Adam10 Deletion And Overexpression In Vivo., David Gibb

Theses and Dissertations

Proteolytic processing of transmembrane receptors and ligands can have dramatic effects on cell signaling and subsequent cellular responses. Previous studies demonstrated that a disintegrin and metalloproteinase 10 (ADAM10) may cleave numerous B cell-expressed receptors, including the low affinity IgE receptor (CD23). However, lethality of ADAM10-deficient embryos has limited examination of these cleavage events in lymphocytes. To investigate their role in B cell development and function, we generated B cell-specific ADAM10 knockout mice. Intriguingly, deletion prevented development of the entire marginal zone B cell (MZB) lineage. Further analysis revealed that ADAM10 is required for S2 cleavage of the Notch2 receptor and …

Delayed Onset Of A Daytime Nap Facilitates Retention Of Declarative Memory, Sara E. Alger, Hiuyan Lau, William Fishbein

Publications and Research

Background Learning followed by a period of sleep, even as little as a nap, promotes memory consolidation. It is now generally recognized that sleep facilitates the stabilization of information acquired prior to sleep. However, the temporal nature of the effect of sleep on retention of declarative memory is yet to be understood. We examined the impact of a delayed nap onset on the recognition of neutral pictorial stimuli with an added spatial component. Methodology/Principal Findings Participants completed an initial study session involving 150 neutral pictures of people, places, and objects. Immediately following the picture presentation, participants were asked to make …

Aesthetic Self-Reliance: Emersonian Influence On American Art, Adrienne Lynn Rumsey

Theses and Dissertations

This essay is an examination of the influence of Ralph Waldo Emerson on the development of American art through his essays, specifically his writings on nature and self-reliance. Through emphasizing individual potential, Emerson also influenced the visual arts. Instead of following the required formula in Europe of attending certain ateliers and seeking prestigious patronage, American artists, namely the Luminists and the Ashcan School, sought to address the issues of their day and portray life as it existed around them. Each of these groups formed during periods of time when American society was shifting and the American identity was evolving. Through …

Cortisol Exerts Bi-Phasic Regulation Of Inflammation In Humans, Mark P. Yeager, Patricia Pioli, Paul M. Guyre

Dartmouth Scholarship

Natural and synthetic glucocorticoids (GCs) have been used for decades to suppress inflammation. In this paper, we re-examine the role of the endogenous GC, cortisol, as a primary homeostatic regulator of the human inflammatory response to injury. Our data show that cortisol regulation of innate immunity can be both pro-inflammatory and anti-inflammatory. Using a human model of in vivo cortisol depletion, we first show that baseline (diurnal) cortisol concentrations do not exert an anti-inflammatory effect. This is the first clue that cortisol regulation of inflammation is not represented by a linear dose-response relationship. We next show in surgical patients that …

Preservice Teachers’ Developing Understandings About Culturally Responsive Teaching In A Field-Based Writing Methods Course, Susan V. Bennett

USF Tampa Graduate Theses and Dissertations

I investigated eight preservice teachers’ understandings about culturally responsive pedagogy as they participated in a writing methods course in which they tutored children from different ethnic, socioeconomic, cultural, and linguistic backgrounds in an afterschool program at a local community center. I also investigated how these preservice teachers demonstrated culturally responsive teaching within the writing curriculum. I recognized the need for research relevant to my own personal beliefs and how to strive for more equitable schools. I want to contribute further to the understandings and insights related to culturally responsive pedagogy. According to the literature, it appears teachers remain unprepared to …

The Role Of Morphology In The Locomotor Performance Of Arboreal Snakes, Ronald C. Rozar

Open Access Dissertations

Adaptation is difficult to directly demonstrate. However, the role that a morphological character, or suite of characters plays in the fitness of a species can be elucidated by examining the intermediate link between morphology and fitness â?? performance. Linking morphology to performance, and then performance to fitness can demonstrate the adaptive significance of a morphological character. Arboreal snakes possess a suite of characteristic morphological traits that differentiate these snakes from their terrestrial counterparts, and these characteristic traits have been presumed to be of an adaptive nature. To determine if these characteristic traits are of an adaptive nature I have taken …

Origin Of The Genus Homo, Holly M. Dunsworth

Sociology and Anthropology Faculty Publications

The origin of the genus Homo in Africa signals the beginning of the shift from increasingly bipedal apes to primitive, large-brained, stone tool-making, meat-eaters that traveled far and wide. This early part of the human genus is represented by three species: Homo habilis, Homo rudolfensis, and Homo erectus. H. habilis is known for retaining primitive features that link it to australopiths and for being the first stone tool makers. Little is known about H. rudolfensis except that it had a relatively large brain and large teeth compared to H. habilis and that it overlapped in time and space with other …

Acaricidal Activity Of Eugenol Based Compounds Against Scabies Mites, Cielo Pasay, Kate Mounsey, Graeme Stevenson, Rohan Davis, Larry G. Arlian, Marjorie Morgan, Diann Vyszenski-Moher, Kathy Andrews, James Mccarthy

Biological Sciences Faculty Publications

Background

Human scabies is a debilitating skin disease caused by the “itch mite” Sarcoptes scabiei. Ordinary scabies is commonly treated with topical creams such as permethrin, while crusted scabies is treated with topical creams in combination with oral ivermectin. Recent reports of acaricide tolerance in scabies endemic communities in Northern Australia have prompted efforts to better understand resistance mechanisms and to identify potential new acaricides. In this study, we screened three essential oils and four pure compounds based on eugenol for acaricidal properties.

Mirnas In Newt Lens Regeneration: Specific Control Of Proliferation And Evidence For Mirna Networking, Kenta Nakamura, Nobuyasu Maki, Albert Trinh, Heidi W. Trask, Jiang Gui, Craig R. Tomlinson, Panagiotis A. Tsonis

Dartmouth Scholarship

Background:

Lens regeneration in adult newts occurs via transdifferentiation of the pigment epithelial cells (PECs) of the dorsal iris. The same source of cells from the ventral iris is not able to undergo this process. In an attempt to understand this restriction we have studied in the past expression patterns of miRNAs. Among several miRNAs we have found that mir-148 shows an up-regulation in the ventral iris, while members of the let-7 family showed down-regulation in dorsal iris during dedifferentiation.

A Monocular Marker-Free Gait Measurement System, Jane Courtney, Annraoi M. De Paor

Articles

This paper presents a new, user-friendly, portable motion capture and gait analysis system for capturing and analyzing human gait, designed as a telemedicine tool to monitor remotely the progress of patients through treatment. The system requires minimal user input and simple single-camera filming (which can be acquired from a basic webcam) making it very accessible to nontechnical, nonclinical personnel. This system can allow gait studies to acquire a much larger data set and allow trained gait analysts to focus their skills on the interpretation phase of gait analysis. The design uses a novel motion capture method derived from spatiotemporal segmentation …

Knowing Your Community: Fostering Biodiversity Awareness In Our Students’ Daily Existence, Tony Cummings Bs, Academic Director

Fostering Multicultural Competence and Global Justice: an SIT Symposium

There are strong arguments suggesting that developing students’ sensitivity to local biodiversity and conservation issues is as important as emphasizing an understanding of global conservation issues happening in faraway lands (Ehrenfeld, 2009). Many students arrive at a Study Abroad destination, with a good understanding of theory, but with little field experience at home. Environmental educators in Study Abroad are able to use the novelty and grandeur of our exotic destinations to systematically teach students the patterns and processes of ecological and human communities at our sites, while inspiring a sense of place in our students. By immersing students in the …

Smaller Is Better: Technical Considerations For Operationally Responsive Space , George Nagy

Small Satellite Conference

The DoD Operationally Responsive Space Office is currently pursuing several initiatives involving small satellites (< 500 kg) to meet combatant commander needs. This paper examines specific technical rationales for why even smaller satellites (1-200 kg) will be necessary if operational responsiveness similar to current aircraft operations is to be achieved--fundamentally changing the concept of space system operations from today's approach.

All Of The Economic Aid The U.S., Eu, And Japan Give To The Developing World Is Stolen Back By Our Illegal Price-Fixing Cartels, Robert H. Lande

All Faculty Scholarship

This compares the magnitudes of two forms of economic interaction between the developed and developing world. The first is the amount of economic foreign aid provided by the developed world to the developing world during a single year. The second is an estimate of the yearly amount that illegal price fixing cartels, comprised of companies from the U.S., the EU, and Japan, overcharge – steal! – from purchasers in these same countries. This comparison shows these amounts are roughly equivalent. If anything, cartels probably steal more from the developing world than the developed world gives them in economic assistance.
