Cogito Ergo Doceo: A Cross-Case Study Of Latin Teacher Cognition In Technology-Rich Communities Of Practice, Ramã³N Anthony Madrigal

USF Tampa Graduate Theses and Dissertations

This empirical research study investigated the phenomenon of ancient language teacher cognition in the technology-rich contexts of two secondary teachers of Latin. Although one teacher was an inexperienced teacher working in a traditional, face-to-face classroom in an independent school, the other teacher was an experienced teacher working at a public virtual school. Features of teacher cognition, such as pre-active planning and inter-active decision-making were examined from a communities-of-practice theoretical perspective (Wenger, 1998). An exploratory, sequential mixed-methods research design was implemented in this cross-case study. Among the research findings that emerged from this investigation was the notion of the expedient integration …

Elements Of Narrative Discourse In Selected Short Stories Of Ernest Hemingway, Gueorgui V. Manolov

USF Tampa Graduate Theses and Dissertations

In the "Art of the Short Story" Hemingway elaborates on his concept of omission as it relates not only to prose writing, but to the special case of writing short stories. Hemingway develops two models to describe his short stories: on the one hand, he describes short stories like "The Sea Change" in terms of omission and exclusion, in terms of leaving the story out of the short story, and on the other, he refers metaphorically to "The Snows of Kilimanjaro" as an airplane loaded with story material which would be enough for four novels. Both models suggest a doubling …

Ethyl Methacrylate And Methyl Methacrylate Exposure Among Fingernail Sculptors, Adam Marty

USF Tampa Graduate Theses and Dissertations

Fingernail sculptors may be exposed to ethyl methacrylate and methyl methacrylate in their workplace. The literature suggests that these chemicals may cause sensitization in individuals who are exposed to sufficient quantities. Cases of occupational asthma and allergic contact dermatitis have been reported among persons who work with these chemicals. Little personal exposure data exists on nail technicians' exposures to these chemicals, especially ethyl methacrylate. The literature suggests that the industrial hygiene practices used for methyl methacrylate also be applied to ethyl methacrylate since more is known about methyl methacrylate. Previous exposure studies have revealed relatively low exposures to these chemical. …

Moving Thumos: Emotion, Image, And The Enthymeme, Eric D. Mason

USF Tampa Graduate Theses and Dissertations

This dissertation connects classical theories regarding the enthymeme and thumos (a Greek word commonly translated as "heart," "mind," or one's "capacity for emotion") to modern theories of images and emotion in order to reconsider the central role of visual discourse in persuasion, ideology, and subject formation. Since "enthymeme" comes from en and thymos, meaning "in heart," etymologically the enthymeme is an argument that is realized in an individual's thumos.

This dissertation thus attempts to establish the notion of thumos in rhetorical studies by developing a theory of visual enthymemes.The understanding of the enthymeme used within this dissertation works less from …

Modulation Of Adult Neural Plasticity By Proteolytic Catabolism Of Lecticans, Joanne Mayer

USF Tampa Graduate Theses and Dissertations

The extracellular environment of the central nervous system (CNS) through which neuritic processes must traverse during development or after injury is complex, and may vary from stabile conditions to a milieu favorable for neural plasticity and growth. The extracellular space in the CNS accounts for about 20% of brain volume and is composed of aggregating complexes of several different extracellular matrix (ECM) molecules. The ECM supports neural networks and acts as a barrier for neurite extention, depending on the type of molecules involved and the various signals they induce. One mechansim that may produce an environment favoring plasticity is the …

Minimally Innate Ideas, Michele Merritt

USF Tampa Graduate Theses and Dissertations

This project provides a detailed examination and critique of current philosophical, linguistic, and cognitive accounts of first language acquisition. In particular, I focus on the concept of "innate" and how it is embraced, marginally utilized, or abandoned altogether in efforts to describe the way that a child comes to be a competent user of a language. A central question that naturally falls out of this general inquiry is therefore what exactly is supposed to be "innate," according to various theories? Philosophically, the theory of innate ideas put forth to explain human learning has existed for centuries and hence, this thesis …

Positive Protective Factors As Moderators In The Relationship Between Relational Victimization And Depression In Minority Adolescents, Stephanie Tamara Mihalas

USF Tampa Graduate Theses and Dissertations

This study explored the relationship between relational victimization and depression among middle school students (n = 153) in an urban school in Florida. The majority of participants were African-American and Hispanic at-risk youth. This study is one of the first to study how positive protective factors (i.e., hope, spirituality, perceived social support) moderate the relationship between victim status and depression. A mixed methods design was used to gain further insight into the survey data collected. Findings from the study indicated that hope and perceived social support were statistically significant moderator variables. Additionally, results from the qualitative interviews suggested that teachers, …

The Effect Of Optional Real World Application Projects On Mathematics Achievement Among Undergraduate Students, David Milligan

Many undergraduate students enrolled in institutions of higher learning wish to connect their learning to real life experiences. By linking reality to academics, students see first hand the practical value in their studies. The purpose of this study was to critically analyze the practice of application projects in undergraduate mathematics courses to determine if, and if so how, students benefit from optional real world application projects. The study was limited to specific courses within a non-math major's undergraduate mathematics program of study at one large research university. Until the appearance of "The Mathematics Umbrella: Modeling and Education" (Grinshpan, 2005), no …

Molecular And Genomic Studies Of Temperate Phages From Halomonas Aquamarina And Bacillus Spp. Isolates From The Gulf Of Mexico, Jennifer M. Mobberley

USF Tampa Graduate Theses and Dissertations

Viruses are the most abundant biological entities in the ocean and are believed to contribute to nutrient cycling, bacterial diversity, and horizontal gene exchange. However, little is known about the relationship between temperate phages and their hosts in marine environments. In this thesis, phage-host systems from the Gulf of Mexico were used to study the influence of temperate phages in bacteria. PhiHAP-1 is a temperate myovirus induced with mitomycin C from Halomonas aquamarina isolate. The genome of this phage was 39,245 nucleotides long and contained 46 predicted genes. Besides genes involved in lysogeny, PhiHAP-1 contained a protelomerase, which is responsible …

Between Knowledge & Practice: Factors That Influence The Operationalization Of Sexual Health Knowledge In African American Female College Students, Jamae F. Morris

USF Tampa Graduate Theses and Dissertations

This paper explores some of the factors that influence whether African American female college students implement safe sex knowledge. High rates of HIV/AIDS and other sexually-transmitted infections (STIs) in the black community and the overrepresentation of individuals under the age of 25 in sexually-transmitted infection (STI) reports indicate the need for research that investigates the physical, social, and cultural aspects of high-risk sexual behaviors and the factors that influence them for this group. African American female college students present a unique challenge to sexual health educators; a challenge that has been relatively under acknowledged and under addressed in research and …

A Three-Dimensional Biophysical Model Of Light, Nutrient, And Grazing Controls On Phytoplankton Competition Affecting Red Tide Maintenance On The West Florida Shel, Scott P. Milroy

USF Tampa Graduate Theses and Dissertations

A coupled, three-dimensional, time-dependent numerical model of water circulation, spectral light, plankton dynamics, nutrient/CDOM loadings, and zooplankton grazing provided an assessment of the factors affecting the growth and maintenance of red tides on the west Florida shelf (WFS). The coupled biophysical model consisted of state variable quantities for temperature, salinity, horizontal/vertical velocity components, turbulent diffusion, spectral light, colored dissolved organic matter (CDOM), dissolved organic and inorganic carbon, particulate silica, four dissolved inorganic nutrient pools (nitrate, ammonium, phosphate, and silicate), and four phytoplankton groups (diatoms, microflagellates, non-toxic dinoflagellates, and the red tide organism Karenia brevis).

The model also included a complex …

Construction And Application Of Computationally Tractable Theories Of Nonlinear Spectroscopy, Christine L. Neipert

USF Tampa Graduate Theses and Dissertations

Nonlinear optical processes probe systems in unique manners. The signals obtained from nonlinear spectroscopic experiments are often significantly different than more standard linear techniques, and their intricate nature can make it difficult to interpret the experimental results. Given the complexity of many nonlinear lineshapes, it is to the benefit of both the theoretical and experimental communities to have molecularly detailed computationally amenable theories of nonlinear spectroscopy. Development of such theories, bench marked by careful experimental investigations, have the ability to understand the origins of a given spectroscopic lineshape with atomistic resolution. With this goal in mind, this manuscript details the …

Depressive Symptomatology, Patient-Provider Communication, And Patient Satisfaction: A Multilevel Analysis, Lorraine Marie Novosel

USF Tampa Graduate Theses and Dissertations

Depression can be a profoundly disabling and costly disorder and is a major public health concern. Despite the efficacy of treatment options, it is often unrecognized, under-diagnosed, and inadequately treated in primary care settings. Research on patient-provider communication supports the connection among the quality of the patient-provider interaction, patient behavior, and health outcomes. The purpose of this study was to systematically examine the impact of patients' depressive symptoms on the patient-provider relationship, patient-provider communication, and patient satisfaction with the primary care office visit. One hundred twenty three patient-provider encounters were audiotaped and coded using the Roter Interaction Analysis System (RIAS). …

The Impact Of Fidelity And Innovations On Healthy Families America Programs, Ashley E. Nixon

USF Tampa Graduate Theses and Dissertations

Fidelity to a program model and innovations added to the program model have been found to positively impact large scale program expansion and implementation (Blakely et al., 1987). Research examining the effectiveness of Healthy Families America (HFA) programs has been hindered by the differences that exist among HFA programs. This study examines the impact program fidelity and innovations have on outcome measures of updated immunizations, primary medical care providers, and participant retention for 102 HFA sites. Factor analysis and regression were used to analyze archival data. Results indicate that fidelity was positively related to percentage of participants with updated immunizations …

Forging Identities Through Style: Elite Interaction And Identity Formation At Late Classic (Ad 650-900) Palmarejo, Northwest Honduras, Claire Novotny

USF Tampa Graduate Theses and Dissertations

The representation of social affiliation is dependent upon material signifiers that can serve as communicative links between individuals or communities. This study evaluates the material manifestation of an elite social identity during the Late Classic (AD 650-900) period at the site of Palmarejo, northwest Honduras. Previous studies on social identity in prehistory point to the importance of site plans, monumental architecture, ceramics, and human burials in conveying sociocultural messages. A regional comparison of these types of data is made between Palmarejo and three coeval sites in northwest Honduras, La Sierra, El Coyote, and Las Canoas. I argue that the chosen …

An Exploration Of Three Residence Hall Types And The Academic And Social Integration Of First Year Students, Dorothy E. Paine

USF Tampa Graduate Theses and Dissertations

Living on campus has long been an important part of many students' collegiate experience. Most research describing the benefits of living on campus was conducted in the 1960s and 1970s and was based upon students living in double rooms on double loaded corridors with community bathrooms. In recent years, the style of residence hall buildings has changed from these traditional rooms to suite and apartment-style housing offering more privacy and greater amenities to students. This study sought to examine how first year students living in three different types of residence hall environments differ on measures of social and academic integration, …

The Role Of Norepinephrine In Learning: Cerebellar Motor Learning In Rats, Daniel A. Paredes

USF Tampa Graduate Theses and Dissertations

Delay classical eyeblink conditioning is an important model of associative, cerebellar dependent learning. Norepinephrine (NE) plays a significant modulatory role in the acquisition of learning; other neurotransmitter systems are also at play. The goal of this dissertation was to determine whether NE, GABA and glutamate (Glu) release is observed in cerebellar cortex during delay eye blink conditioning, and whether such release was selectively associated with training and not due only to stimulatory sensory input. The data support the hypothesis of noradrenergic and GABAergic system involvement in motor learning with NE as a modulator of early responding and GABA as a …

Two Essays On Market Efficiency ⎯ Tests Of Idiosyncratic Risk: Informed Trading Versus Noise And Arbitrage Risk, And Agency Costs And The Underlying Causes Of Mispricing: Information Asymmetry Versus Conflict Of Interests, Jung Chul Park

USF Tampa Graduate Theses and Dissertations

I examine the informational efficiency of stock markets by testing the relation between idiosyncratic volatility and equity mispricing. I find that the level of mispricing declines with idiosyncratic volatility consistent with the notion that greater levels of firm-specific risk reflect greater participation of informed traders in the market for the stock. However, I also find that mispricing increases with idiosyncratic volatility for highly volatile stocks, and this is attributed to both noise trading and arbitrage risk. In addition, I investigate the link between agency costs and equity mispricing, and whether it exists due to information asymmetry or the degree of …
