An Explanatory Examination Of Relationships Between Measures Of School And Student Socioeconomic Status And Reading And Math Achievement Of Hispanic Limited English Proficient (Lep) High School Students, Osvaldo Piedra

USF Tampa Graduate Theses and Dissertations

Hispanics are the largest and fastest growing minority population in the U.S. requiring limited English proficiency services (Guglielmi, 2008). Many schools and school districts place heavy emphasis on high stakes testing. The No Child Left Behind (NCLB) Act of 2001 requires all children to have access to a fair, equal, and high-quality education. Many schools and school districts focus on individual students to show grade level performance for small populations such as limited English proficient (LEP) students. The purpose of this study was to examine the question, "What was the relationship between measures of school and student socioeconomic status, and …

Biotopia: An Interdisciplinary Connection Between Ecology, Suburbia, And The City, Jessica Phillips

USF Tampa Graduate Theses and Dissertations

In an era when cities and towns are changing rapidly, public spaces are the key to reviving civic engagement. By re-introducing these public realms as ecological environments, we can re-structure the organic growth of civic tissue, re-define the city street into a park environment, and reveal the ecological landmarks that once beautified the landscape. These ecological landmarks will be used as corridors, nodes of circulation and storm water management to not only creates a regenerative landscape but to create a connection between ecology, suburbia and the city. The public realm in America has two roles: it is the dwelling place …

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 …

Mentorship Racial Composition And The Judgments Made By Individuals External To The Relationship, Laura F. Poteat

USF Tampa Graduate Theses and Dissertations

The purpose of this study was to examine how the racial composition of a mentoring relationship influences three types of judgments made by individuals external to the relationship: (1) causal attributions formed to explain successful protégé performance; (2) evaluations of protégé career advancement potential; and (3) reward recommendations for the mentor and protégé. Additionally, the associations among causal attributions, evaluations of potential, and reward recommendations were investigated. A 2 (protégé race: white vs. black) x 2 (mentor race: white vs. black) factorial between-subjects design was used. Mentor and protégé races were manipulated within a written vignette.

Experience + Evolution: Exploring Nature As A Constant In An Evolving Culture And Building Type, Robin Plotkowski

USF Tampa Graduate Theses and Dissertations

Throughout time, our natural environment has been one of the only constants in our evolution. While cultures change and evolve, nature's beauty and positive effects on humans have always been present. Unfortunately, our built environment has generated much attention for its profound impact on our natural environment. Buildings in the United States consume a third of our total energy use, raw material use, and waste output, not to mention the negative effects they can have on our well-being, economy, health and productivity. In an effort to protect our natural environment, our built environment must become more responsible to the environment …

Practices For Dispreferred Responses Using "No" By A Learner Of English, John Hellermann

Applied Linguistics Faculty Publications and Presentations

Responding in a manner that does not align with an action or affiliate with a stance implicated in just prior talk is potentially sensitive work. Conversation Analysis (CA) has shown that participants orient to the sensitive nature of sequences of talk used to project responses that do not align, or, are dispreferred (Pomerantz 1984) in some way. This paper examines such responses, especially with the use of no tokens. The talk comes from the interactions of one adult learner of English in a language learning classroom over the course of five ten-week terms. The findings show that the participant’s use …

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 …

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. …

Determination Of Nanogram Mass And Measurement Of Polymer Solution Free Volume Using Thickness-Shear Mode (Tsm) Quartz Resonators, Anthony James Richardson

USF Tampa Graduate Theses and Dissertations

More commonly referred to as a quartz crystal microbalance (QCM), thickness-shear mode (TSM) quartz resonator devices utilize an acoustic wave to establish a bulk-detection mechanism prompting their utilization as gravimetric sensors with nanogram mass sensitivity and capability to measure various film property dynamics, due to variations in the system environment, of thin-films that are uniformly distributed across the resonator surface. The development of an absolute TSM-based nanobalance and an experimental technique using conventional TSM resonators for the real-time measurement of the change in the viscoelastic shear modulus and fractional free-hole volume of a poly(isobutylene) film due to the sorption of …

Proxy Records Of Climate Change In Subtropical And Tropical Karst Environments, Jason Samuel Polk

USF Tampa Graduate Theses and Dissertations

Understanding the paleoclimate of a region is important, especially when trying to determine the extent of natural climate variability within the context of anthropogenic impacts. Recent anomalous periods of climate change in the Late Holocene, including the Little Ice Age and Medieval Warm Period, could possibly repeat in the future, having significant worldwide consequences. This holds especially true for tropical and subtropical karst environments, where limited paleoclimate proxies provide minimal data regarding past climate change. An investigation into past climate change in Belize using fulvic acids from cave sediments shows periods of drought during the collapse of the Maya society …

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 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. …

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) …

Relationships Between Participation In Athletics And Substance Use Among School Students, Kevin M. Stockslager

USF Tampa Graduate Theses and Dissertations

Substance use among high school students has become an increased concern for administrators, parents, and community members. Previous research has demonstrated relationships between adolescent substance use and numerous negative outcomes. This study investigated the relationship between athletic participation and substance use using self-report data from a sample of 139 high school students. Specifically, the current study examined the relationship between frequency and setting of participation in athletic activities (e.g., football, baseball, soccer) and multiple types of substance use (e.g., alcohol, tobacco, marijuana, other illicit drugs) in adolescents. The results of this study indicate that nonathletes reported significantly more marijuana use …

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 …

Calculating The Volume Of The May 18, 1980 Eruption Of Mount St. Helens, Dâvid Nuñez Wickham

Environmental Science and Management Professional Master's Project Reports

The May 18, 1980 eruption of Mount St. Helens created a massive amount of sediment and debris, thought to be as much as 5.5 billion cubic yards. This sediment causes infill of river stretches and collects along levees protecting southwest Washington State. The sediment must be removed to ensure these areas do not flood. The US Army Corps of Engineers (USACOE) is tasked with flood protection for southwest Washington State and the levees protecting the cities of Castle Rock, Lexington, Kelso, and Longview. The Sediment Retention Dam, opened in 1989 is able to filter out larger particulate but fine grain …

Immigrant-Established Resident Interactions In Miami, Florida, Alex Stepick, Carol Dutton Stepick

Sociology Faculty Publications and Presentations

This article examines factors that affect interethnic relations in Miami, Florida. The theoretical framework, based on the ‘contact hypothesis’ argues that better interethnic relations stem from not only contact, but also contact in which individuals from opposing groups share equal status and a stake in outcomes, and when contact activities require cooperation. The contact hypothesis, however, does not address the factors that produce inequality in social relations. To address these factors ideas from international migration research are used to argue that those with power must create structures in which other groups feel welcome rather than rejected and that leaders must …

Esl Placement And Schools: Effect On Immigrant Achievement, Rebecca Callahan, Lindsey Wilkinson, Chandra Muller, Michelle Frisco

Sociology Faculty Publications and Presentations

In this study, the authors explore English as a Second Language (ESL) placement as a measure of how schools label and process immigrant students. Using propensity score matching and data from the Adolescent Health and Academic Achievement Study and the National Longitudinal Study of Adolescent Health, the authors estimate the effect of ESL placement on immigrant achievement. In schools with more immigrant students, the authors find that ESL placement results in higher levels of academic performance; in schools with few immigrant students, the effect reverses. This is not to suggest a one-size-fits-all policy; many immigrant students, regardless of school composition, …

The Impact Of Adolescent Neighborhood And School Context On Asian And Latino Young Adults’ Native Language Use With Family, Lindsey Wilkinson

Sociology Faculty Publications and Presentations

While opponents of immigration often claim that the new immigrants are failing to learn English and thus to assimilate, a growing body of research suggests otherwise. In fact, Anglicization, or loss of mother tongue, is occurring at a rapid rate across all groups of new immigrants (Alba et al. 2002; Lopez 1999; Portes and Hao 1998; Veltman 1983) and continues to follow the three generation pattern observed among earlier waves of European immigrants (Fishman 1965). However, there is evidence that this shift is occurring more rapidly for Asian immigrants than for Latinos (Alba et al. 2002; Lopez 1999), due in …

Differences In Physical And Mental Health Symptoms And Mental Health Utilization Associated With Intimate Partner Violence Vs. Child Abuse, Christina Nicolaidis, Bentson H. Mcfarland, Maryann Curry, Martha Gerrity

School of Social Work Faculty Publications and Presentations

Background: There is ample evidence that both intimate-partner violence (IPV) and childhood abuse adversely affect the physical and mental health of adult women over the long term. Objective: The authors assessed the associations between abuse, symptoms, and mental health utilization. Method: The authors performed a cross-sectional survey of 380 adult female, internal-medicine patients. Results: Although both IPV and childhood abuse were associated with depressive and physical symptoms, IPV was independently associated with physical symptoms, and childhood abuse was independently associated with depression. Women with a history of childhood abuse had higher odds, whereas women with IPV had lower odds, of …

Effects On L1 During Early Acquisition Of L2: Speech Changes In Spanish At First English Contact, Christina E. Gildersleeve-Neumann, Elizabeth D. Peña, Barbara L. Davis, Ellen S. Kester

Speech and Hearing Sciences Faculty Publications and Presentations

Spanish phonological development was examined in six sequential bilingual children at the point of contact with English and eight months later. We explored effects of the English vowel and consonant inventory on Spanish. Children showed a significant increase in consonant cluster accuracy and in vowel errors. These emerging sequential bilingual children showed effects of English on their first language, Spanish. Cross-linguistic transfer did not affect all properties of the phonology equally. Negative transfer may occur in specific areas where the second language is more complex, requiring reorganization of the existing system, as in the transition from the Spanish five-vowel to …
