Effects Of Dialect Use On The Fast Mapping Skills Of African American School-Age Children, Jessica Pierre

USF Tampa Graduate Theses and Dissertations

Previous research has shown that African American children are prone to score lower on vocabulary tests when compared to their white peers (Champion et al., 2003; Qi et al., 2006; Restrepo et al., 2006; Thomas-Tate et al., 2006; Washington & Craig, 1992). The dialect spoken by these children may be affecting their performance. However, little is known about how dialect use interacts with word learning abilities. The current study continues a project initiated by Wyatt, Bahr, and Silliman (2007) which examined dialectal influences on the fast mapping of novel stimuli in preschool children. The participants in the current study were …

Cocrystals Of Nutraceuticals: Protocatechuic Acid And Quercetin, Twarita Anil Pujari

USF Tampa Graduate Theses and Dissertations

The cocrystallization of two or more pure compounds by crystal engineering to create a new functional material is of a great academic and industrial interest. Pharmaceutical cocrystallization has allured a lot of attention by means of altering the physicochemical properties of Active Pharmaceutical Ingredient (API) such as solubility, stability and bioavailability. Crystal engineering of nutraceuticals can produce novel compounds such as pharmaceutical cocrystals. To establish the importance of nutraceutical cocrystallization and its use; polyphenols, a major class of nutraceuticals and potential disease preventing agents, are the appropriate targets. The work herein focuses on two polyphenols, protocatechuic acid and quercetin, which …

Digital Holography Applications In Ophthalmology, Biometry, And Optical Trapping Characterization, Mariana Camelia Potcoava

USF Tampa Graduate Theses and Dissertations

This dissertation combines various holographic techniques with application on the two- and three-dimensional imaging of ophthalmic tissue, fingerprints, and microsphere samples with micrometer resolution. Digital interference holography (DIH) uses scanned wavelengths to synthesize short-coherence interference tomographic images. We used DIH for in vitro imaging of human optic nerve head and retina. Tomographic images were produced by superposition of holograms. Holograms were obtained with a signal-to-noise ratio of approximately 50 dB. Optic nerve head characteristics (shape, diameter, cup depth, and cup width) were quantified with a few micron resolution (4.06 -4.8 microns). Multiple layers were distinguishable in cross-sectional images of the …

Depredation And Angler Interactions Involving Bottlenose Dolphins (Tursiops Truncatus) In Sarasota Bay, Florida, Jessica R. Powell

USF Tampa Graduate Theses and Dissertations

Typical depredation behavior by cetaceans involves stealing or damaging prey items already captured by recreational or commercial fishing gear. Depredation among cetaceans has been reported to be increasing in both severity and frequency globally. This behavior is of particular concern for small stocks of cetaceans since any interaction with fishing gear has the potential to injure or kill animals leading to unsustainable losses. In Florida, depredation became evident in 2006 when the number of bottlenose dolphin (Tursiops truncatus) strandings resulting from fishing gear ingestion or entanglement sharply increased. For the resident dolphin community in Sarasota Bay, modeling showed continued mortalities …

It also represents an extension of surrealists like Lamantia and Ashbery.

Nature, Daylight And Sound: A Sensible Environment For The Families, Staff And Patients Of Neonatal Intensive Care Units, Ana Praskach

USF Tampa Graduate Theses and Dissertations

In healthcare environments, elements like nature, daylight and sound have been found to significantly influence the healing process of patients, by enhancing the quality of their recovery, shortening their hospital stay and consequently reducing hospital costs. For instance, it has been shown that exposure to nature triggers positive responses in people, daylight affects human psychology, and different sounds have varying behavioral effects on different groups of people. But, while these effects have been carefully studied in adult patients, leading to clear design standards, less is known about their impact on premature infants. Interestingly, the care that many newborns receive in …

Agriculture And Tampa Bay News: How Do Local News Media Frame Agribusiness?, Alex R. Ritzheimer

USF Tampa Graduate Theses and Dissertations

The purpose for this thesis was to explore a dynamic between the news media, their subjects, and their audience. I investigate whether everyday news media frame the information they deliver in such a way as to potentially direct the audience on how to respond to news stories. The setting for this research question is in the Tampa Bay area of Florida and the subject matter deals specifically with agriculture, its practitioners, how they do business, and how the local news media report about it. The issue will be explored from an applied anthropological perspective, basing conclusions on field research and …

Cultural Response To Totalitarianism In Select Movies Produced In Czechoslovakia, Hungary And Poland Between 1956 And 1989, Kazimierz Robak

USF Tampa Graduate Theses and Dissertations

This study examines resistance against totalitarian propaganda in select movies produced in regions subjected to Soviet-imposed totalitarian system. From 1939 to the collapse of the Soviet Union in 1991, Central-Eastern Europe has experienced two of the most devastating and genocidal political systems in the history of the humankind. Nazism was destroyed with the end of WWII, and met widespread condemnation. Sovietism, commonly known as Communism, survived WWII and the Soviet totalitarian empire rose to the position of the world's second superpower. Effective and organized Soviet propaganda generated a new convincing image of Sovietism as a harmless, friendly and progressive system. …

Transdiscursive Cosmopolitanism: Foucauldian Freedom, Subjectivity, And The Power Of Resistance, Joanna Rozpedowski

USF Tampa Graduate Theses and Dissertations

The following project will consist in the study and examination of the concepts and theories that lie in the domain of political theory. The enquiry into the dimensions and complexities of the socio-political organization and the political substance of individual human agents will be conducted with the intellectual assistance of the postmodernist turn of thought. I will interrogate and develop a specifically Foucauldian reading of international politics and the emerging global world order as well as situate Foucault's insights and theorizing in a cosmopolitan framework, which calls for a progressive re-conceptualization of the dimensions of power and the modalities of …

Evolution Of A Conserved Gene Regulatory Network Among Echinoderms: A Comparison Of Genes Expressed In The Skeletogenetic Lineage Of The Ophuroid Ophiocoma Wendtii And The Echinoid Strongylocentrotus Purpuratus, Mitch James Ruzek

USF Tampa Graduate Theses and Dissertations

One of the most fundamental and critical functions of embryological development is the control and regulation of differential genes and gene networks. The study of the gene networks involved in development is a mechanism for understanding the developmental process at its most basic level. An evolutionary change in a morphological feature or features must depend on a reorganization or co-option of one or more developmental gene regulatory network just as retention of an ancestral morphological trait must rely on retention of a common gene regulatory network. Studying two closely related classes in the same phylum with the same essential morphological …

The Mashup As Resistance? A Critique Of Marxist Framing In The Digital Age, Adam Rugg

USF Tampa Graduate Theses and Dissertations

This thesis critiques contemporary scholarly approaches to the modern musical mashup that rely on outdated and over-generalized Marxist frameworks. These frameworks stem from an Adornian view of the culture industries that places consumers and producers in distinct and opposing roles. The mashup is therefore seen as little more than a subversive weapon for a resistant consumer class in its fight against the hegemonic structure of the mass media. A case study of the prominent mashup artist Girl Talk is presented to illustrate how the mashup can actually function as a celebratory form and how modern technological advances have destabilized traditional …

The Effects Of Processing Instruction, Structured Input, And Visual Input Enhancement On The Acquisition Of The Subjunctive In Adjectival Clauses By Intermediate-Level Distance Learners Of Spanish, Victoria Russell

USF Tampa Graduate Theses and Dissertations

This study investigated the effects of processing instruction (PI) on the acquisition of the subjunctive in adjectival clauses by 92 intermediate-level distance learners of Spanish. PI is a novel instructional technique that is based on VanPatten's principles of input processing (1993, 1996, 2002, 2004), and it has three key components: (a) an explicit explanation of grammar that is not paradigmatic, (b) information on processing strategies, and (c) structured input tasks and activities. Structured input activities were isolated and combined with computerized visual input enhancement (VIE) in an attempt to increase the salience of targeted grammatical forms for web based delivery. …

Impacts Of Alterations Of Organic Inputs On The Bacterial Community Within The Sediments Of Wind Cave, South Dakota, Usa, Marisa K. Chelius, Guy Beresford, Howard Horton, Meghan Quirk, Greg Selby, Rodney T. Simpson, Rodney Horrocks, John C. Moore

International Journal of Speleology

Wind Cave (WICA) in the Black Hills of South Dakota, like many mostly dry caves in temperate regions is an energy-starved system. The biotic communities that reside in these systems are low in diversity and simple in structure, and sensitive to changes in external inputs of organic matter. Caves open to tourist traffic offer an opportunity to study the impacts of organic matter amendments in the form of human and rodent hair and dander, clothing lint, material from rodent activity (nesting materials and feces), and algal growth in and around artificial lighting. This study reports on the impacts of carbon …

Guanophilic Fungi In Three Caves Of Southwestern Puerto Rico, Ángel M. Nieves-Rivera, Carlos J. Santos-Flores, Frank M. Dugan, Thomas E. Miller

International Journal of Speleology

Fifty species of guanophilic (bat guano-loving) fungi were isolated from field-collected samples within three caves in southwestern Puerto Rico; most were mitosporic fungi (23 species). The caves studied were Cueva La Tuna (Cabo Rojo), Cueva de Malano (Sistema de Los Chorros, San Germán), and Cueva Viento (El Convento Cave-Spring System, Guayanilla-Peñuelas). The most conspicuous fungus by far was the zygomycete Circinella umbellata (Mucorales). Circinella umbellata dominated the bat guano incubation chambers (Petri dishes lined with sterile filter paper moistened with sterile water) at ambient laboratory conditions. Nineteen species of basidiomycetes (e.g., Ganoderma cf. resinaceum, Geastrum cf. minimum, Lepiota …

Observations On The Cave-Associated Beetles (Coleoptera) Of Nova Scotia, Canada, Max Moseley

International Journal of Speleology

The cave-associated invertebrates of Nova Scotia constitute a fauna at a very early stage of post-glacial recolonization. The Coleoptera are characterized by low species diversity. A staphylinid Quedius spelaeus spelaeus, a predator, is the only regularly encountered beetle. Ten other terrestrial species registered from cave environments in the province are collected infrequently. They include three other rove-beetles: Brathinus nitidus, Gennadota canadensis and Atheta annexa. The latter two together with Catops gratiosus (Leiodidae) constitute a small group of cave-associated beetles found in decompositional situations. Quedius s. spelaeus and a small suite of other guanophiles live in accumulations of …

Aspen Succession And Nitrogen Loading: A Case For Epiphytic Lichens As Bioindicators In The Rocky Mountains, Usa, Paul C. Rogers, Kori D. Moore, Ronald J. Ryel

Wildland Resources Faculty Publications

Question: Can lichen communities be used to assess shortand long-term factors affecting seral quaking aspen (Populus tremuloides) communities at the landscape scale? Location: Bear River Range, within the Rocky Mountains, in northern Utah and southern Idaho, USA. Method: Forty-seven randomly selected mid-elevation aspen stands were sampled for lichens and stand conditions. Plots were characterized according to tree species cover, basal area, stand age, bole scarring, tree damage, and presence of lichen species. We also recorded ammonia emissions with passive sensors at 25 urban and agricultural sites throughout an adjacent populated valley upwind of the forest stands. Nonmetric multidimensional scaling (NMS) …

Natural processes tend to vary over time and space, as well as between species. The ecosystem services these natural processes provide are therefore also highly variable. It is often assumed that ecosystem services are provided linearly (unvaryingly, at a steady rate), but natural processes are characterized by thresholds and limiting functions. In this paper, we describe the variability observed in wave attenuation provided by marshes, mangroves, seagrasses, and coral reefs and therefore also in coastal protection. We calculate the economic consequences of assuming coastal protection to be linear. We suggest that, in order to refine ecosystem-based management practices, it is …

Introduction To Common Native And Potential Invasive Freshwater Plants In Alaska, Vanessa Howard Morgan, Mark Sytsma

Center for Lakes and Reservoirs Publications and Presentations

Freshwater aquatic plants are found in most lakes and rivers in Alaska. They range from tiny floating plants that can form mats on a lake surface to emergent plants growing two meters above the water. Aquatic plants are an important part of freshwater environments. They provide food and shelter for a wide variety of insects, fish, mammals, and birds; stabilize shorelines; and form an important link in nutrient cycles. To date, Alaska has had relatively few problems with invasive, non-native aquatic plants. However, invasive aquatic plants pose an increasing threat to human safety and the integrity of native aquatic communities. …

Characterization Of Nprc And Its Binding Partners, Abdel A. Alli

USF Tampa Graduate Theses and Dissertations

The C type natriuretic peptide receptor (NPRC) also known as NPR3 is a widely expressed single transmembrane-spanning protein. NPRC functions as a homodimer at the cell surface for the metabolic clearance of a broad range of natriuretic peptides from circulation. The intracellular domain of NPRC is coupled to inhibitory G proteins and is involved in mediating signal transduction. In order to further elucidate the role of NPRC in signal transduction a proteomic approach was taken to identify putative protein binding partners for NPRC in different cell-types. An interrogation of the molecular association between NPRC and its identified protein binding partner(s) …

The Importance Of Benthic Habitats As Reservoirs Of Persistent Fecal Indicator Bacteria, Brian D. Badgley

USF Tampa Graduate Theses and Dissertations

Enterococci are fecal indicator bacteria (FIB) that are used worldwide for water

quality assessment. However, evidence of high densities and extended survival of

enterococci in sediments and submerged aquatic vegetation (SAV) has caused uncertainty

about their reliability in predicting human health risks from recreational activities in

environmental waters. To address the concern that sediments and SAV may harbor large

reservoirs of enterococci that can affect water column concentrations, aquatic mesocosms

and environmental sampling were employed to investigate patterns of enterococci

densities and population structure across the Tampa Bay watershed.

In mesocosm experiments and environmental samples, SAV harbored higher

densities of …
