Teacher Efficacy And Student Achievement In Ninth And Tenth Grade Reading: A Multilevel Analysis, Anete Vasquez

USF Tampa Graduate Theses and Dissertations

More than 8 million of America's middle and high school students are struggling readers. Two-thirds of all eighth graders read below grade level, and the reading scores of high school students have not improved since 1974. Low literacy levels affect learning in all subject areas and impede student opportunity for future success. The No Child Left Behind Act of 2001 and the accountability measures associated with the Act have heightened public awareness of the deficiency in adolescent literacy. School districts are choosing to respond in one of two ways. Some school districts are opting to invest in teacher-proof curricula that …

Epifaunal Assemblage Of A Newly Established Oyster Reef With Two Substrates, Ian M. Dow

USF Tampa Graduate Theses and Dissertations

An artificial oyster reef constructed in Boca Ciega Bay, off of the War Veteran's Memorial Park, St. Petersburg, Florida, in 2005, was used to compare a mined shell material to the typical oyster shell substrate used in artificial reef projects as an alternative substrate and cultch material. Half of the reef's veneer was the fresh oyster shell and the other half was mined material. Experimental trays were deployed on top of the sediment along the leeward reef base and sampled quarterly to test the hypothesis that fresh shell is the preferential cultch material of the Eastern Oyster, Crassostrea virginica, promoting …

Error Related Negativity In Parkinson’S Disease: A Test Of The Validity Of Mesencephalicdopamine Contributions To Ern, Craig A. Siders

USF Tampa Graduate Theses and Dissertations

A model proposed by Holroyd and Coles (2002) stating that error related negativity (ERN) is caused by a decrease in mesencephalic dopamine output to the ACC was tested. A group of individuals with Parkinson's disease (N = 16) and an age and education matched group free from neurological disorder (N = 16) completed a card guessing task where the magnitude of monetary penalties and rewards for incorrect and correct answers was varied by block. Individuals with Parkinson's disease were tested after an overnight washout from dopamingeric medications.

The amplitude of the mid-frontal negativity elicited by feedback was analyzed with spatial …

Utilitarian Approaches For Multi-Metric Optimization In Vlsi Circuit Design And Spatial Clustering, Upavan Gupta

USF Tampa Graduate Theses and Dissertations

In the field of VLSI circuit optimization, the scaling of semiconductor devices has led to the miniaturization of the feature sizes resulting in a significant increase in the integration density and size of the circuits. At the nanometer level, due to the effects of manufacturing process variations, the design optimization process has transitioned from the deterministic domain to the stochastic domain, and the inter-relationships among the specification parameters like delay, power, reliability, noise and area have become more intricate. New methods are required to examine these metrics in a unified manner, thus necessitating the need for multi-metric optimization. The optimization …

The Effects Of Depressed Mood On Academic Outcomes In Adolescents And Young Adults, Robert Christopher Jones

USF Tampa Graduate Theses and Dissertations

The following dissertation investigates the relationship between depressed mood and academic performance (measured in terms of grade point average) in U.S. middle and high schools.

Utilizing data from AddHealth, the dissertation establishes Ordinary Least Squares, Two-Stage Least Squares (2SLS), and individual and sibling fixed effect regressions that attempt to control for confounding factors, including student motivation, personality characteristics, and parental inputs that are unobserved but may influence both mental health and achievement.

Study findings indicate that students who report feeling depressed do not perform as well academically as non-depressed students. Additionally, the degree of GPA impact increases with the severity …

Advancement And Optimization Of An Electrospray Injection Based In-Vacuum Patterning System For Macromolecular Materials, Andreas Stark

USF Tampa Graduate Theses and Dissertations

Electrospray ionization is a technique widely used in mass spectrometry. Almost every material, specifically large molecules like proteins or polymers can be ionized directly out of solution. During the ionization process molecules are not fragmented. In this work a prototype apparatus for creating three-dimensional patterns in a ultra high vacuum environment using an electrospray ion source was optimized for higher ion currents hence deposition rate by improving the core component of the apparatus, an electrodynamic ion funnel. The major improvements are a redesigned heated vacuum inlet, modified gas flow inside the ion funnel because of sealing the ion funnel against …

Two Essays On Corporate Governance⎯Are Local Directors Better Monitors, And Directors Incentives And Earnings Management, Hong Wan

USF Tampa Graduate Theses and Dissertations

Previous literature have documented that the independent directors play a crucial goal in corporate governance but the research on the firm value and board independence remains inconclusive. In my dissertation, I examine the impact of independent directors' geographic proximity to corporate headquarters on the effectiveness of corporate boards and the motivations of board directors. Using a large sample of directors trading, I show that independent directors who live close to headquarters ("local director") earn higher abnormal returns on their trades than other directors, and that this advantage is stronger in small firms. Further, I find an inverse relationship between the …

Yeats, Eliot, And Apocalyptic Poetry, Nancy Helen Fletcher

USF Tampa Graduate Theses and Dissertations

Yeats and Eliot merit comparison because they wrote poetry that has been described as apocalyptic in the same historical period and in the same general geographic area but described entirely different visions. These particular works of Yeats and Eliot are appropriate because they represent two widely varying viewpoints on the causes, nature and desirability of what each author felt would be the coming apocalypse. Therefore, more can be learned by comparing the very different outlooks of the poems than by considering each poem separately.

Yeats sees humanity as both the victim and the beneficiary of a series of inescapable historical …

Patch Reefs In Biscayne National Park, Fl: Sediments, Foraminiferal Distributions, And A Comparison Of Three Biotic Indicators Of Reef Health, Alexa Ramirez

USF Tampa Graduate Theses and Dissertations

Coral cover remains highest on patch reefs at the northern end of the Florida reef tract. The reasons for this trend are not well understood, but may be related to the protection from extreme variations in water quality parameters provided by the near constant presence of islands at the north extent of the Florida Keys.

Three indices have been developed based on Foraminifera and sediment constituents. Two of the indices, the FORAM Index and the SEDCON Index, were developed to indicate the suitability of a reef environment for continued reef accretion. The third index, the Photic Index, is an assessment …

Manufacturing Process Design And Control Based On Error Equivalence Methodology, Shaoqiang Chen

USF Tampa Graduate Theses and Dissertations

Error equivalence concerns the mechanism whereby different error sources result in identical deviation and variation patterns on part features. This could have dual effects on process variation reduction: it significantly increases the complexity of root cause diagnosis in process control, and provides an opportunity to use one error source as based error to compensate the others.

There are fruitful research accomplishments on establishing error equivalence methodology, such as error equivalence modeling, and an error compensating error strategy. However, no work has been done on developing an efficient process design approach by investigating error equivalence. Furthermore, besides the process mean shift, …

The Effects Of Pre-Writing Strategy Training Guided By Computer-Based Procedural Facilitation On Esl Students’ Strategy Use, Writing Quantity, And Writing Quality, Darunee Dujsik

USF Tampa Graduate Theses and Dissertations

Pre-writing strategies are conscious thoughts, actions, or behaviors used by writers when they plan before writing. Research in second language writing suggests that specific writing strategies related to writing purposes, audience, brainstorming, and organizing ideas are teachable and have a potential to improve the quantity and quality of writing produced by English as second language (ESL) learners. This study investigated the effects of computer-based pre-writing strategy training guided by procedural facilitation (Bereiter & Scardamalia, 1987) on intermediate ESL students' writing strategy use, writing quantity, and writing quality.

A sequential mixed methods design was utilized with an initial quasi-experimental phase followed …

On A Conjecture Involving Fermat's Little Theorem, John Clark

USF Tampa Graduate Theses and Dissertations

Using Fermat’s Little Theorem, it can be shown that Σ^m_i=1 i ^m−1 ≡ −1 (mod m) if m is prime. It has been conjectured that the converse is true as well. Namely, that Σ^m_i=1 i ^m−1 ≡ −1 (mod m) only if m is prime. We shall present some necessary and sufficient conditions for the conjecture to hold, and we will demonstrate that no counterexample exists for m ≤ 10¹² .

High-Rise Neighborhood: Rethinking Community In The Residential Tower, Benjamin Hurlbut

USF Tampa Graduate Theses and Dissertations

Within the United States, a growing sense of detachment exists. Conditions in both urban and suburban contexts have created a sense of social detachment where spaces do not exist which encourage social interaction. Without this social activity, neighbors become almost a disposable commodity as relationships never fully develop. This thesis will be an examination of environments which do and do not foster community relationships and an implementation of community into an urban multi-family residence.

A major part of the problem is the recent move to the suburbs, but urban buildings also exhibit a lack of spaces which help encourage a …

Psychometrics Of Osce Standardized Patient Measurements, Frederick R. B Stilson

USF Tampa Graduate Theses and Dissertations

This study examined the reliability and validity of scores taken from a series of four task simulations used to evaluate medical students. The four role-play exercises represented two different cases or scripts, yielding two pairs of exercises that are considered alternate forms. The design allowed examining what is essentially the ceiling for reliability and validity of ratings taken in such role plays. A multitrait-multimethod (MTMM) matrix was computed with exercises as methods and competencies (history taking, clinical skills, and communication) as traits. The results within alternate forms (within cases) were then used as a baseline to evaluate the reliability and …

Evaluation Of Contraflow Lanes For Hurricane Evacuation, Jason Collins

USF Tampa Graduate Theses and Dissertations

This dissertation evaluates contraflow during a hurricane evacuation for grade separated highways. Contraflow is the concept of reversing the typical direction of highway travel to provide more outbound roadway capacity. The State of Florida has spent more time and resources towards the planning and the designing of potential contraflow facilities than any other state in the country; however, contraflow has yet to be implemented (as of Summer 2008). This study determines if the additional capacity benefits of contraflow outweigh the logistical requirements of implementing contraflow. Five different alternatives of contraflow lane configurations were comparatively evaluated. The format of this study …

Analysis Of The Role Of Bhlh/Pas Proteins In Aryl Hydrocarbon Receptor Signaling, Edward J. Dougherty

USF Tampa Graduate Theses and Dissertations

The aryl hydrocarbon receptor (AHR) is a basic helix-loop-helix PER/ARNT/SIM (bHLH-PAS) transcription factor that binds ligands typified by 2,3,7,8-tetracholordibenzo-p-dioxin, translocates to the nucleus, dimerizes with the aryl hydrocarbon nuclear translocator (ARNT) and associates with specific cis xenobiotic response elements to activate transcription of genes involved with xenobiotic metabolism. AHR-mediated signal transduction has been evaluated thoroughly in the C57BL/6J mouse model system. This model system, however, may not be the most accurate model for human comparisons as the AHR^b-1 allele carried by C57BL/6J contains a point mutation that prematurely truncates the receptor at 805 amino acids, while the AHR^{b-2 …}

Facilitating Communication And Effective Interpersonal Relationships At Work: A Theoretical Model Of Socio-Affective Competence, Adam C. Bandelli

USF Tampa Graduate Theses and Dissertations

The research reported here provides an introduction to a theoretical model of socio-affective competence. This conceptual model of social effectiveness consists of four competencies that are related to the development of effective interpersonal relationships in the workplace. These competencies include: establishing rapport, promoting acceptance of differences, developing trust and cultivating charismatic influence. The socio-affective competence model was formulated in an attempt to integrate research on social and emotional skills that have been linked to performance in organizations. The current research proposed the model and defined its competency areas, designed a socio-affective competence situational judgment test (SAC-SJT), identified the variables that …

The Development And Validation Of The Comprehensive Team Interdependence Scale, Michael E. Rossi

USF Tampa Graduate Theses and Dissertations

The purpose of this study was to review the existing teams research which suggests that teams vary along 4 dimensions of interdependence. Task interdependence is the extent to which the task drives interactions among individuals. Resource interdependence is the extent to which individuals rely on others to provide inputs necessary to complete their portion of work. Reward interdependence is the extent to which individuals' rewards are tied into the performance of others. Finally, goal interdependence is the extent to which individuals set goals and receive feedback at the group versus individual level. A comprehensive team interdependence scale tapping into these …

The Role Of Occupational Values And Support In Career Choice: An Emphasis On Women In Science, Heather Meikle

USF Tampa Graduate Theses and Dissertations

The purpose of this study was to determine how occupational values and social support for career pursuits influenced career choice, with a specific focus on women in science, technology, engineering, or mathematics (STEM). A sample of 62 college graduates participated in telephone interviews that addressed gender differences in seven occupational values and three sources of social support. Results showed that differences in occupational values differ by both gender and between individuals in STEM and non-STEM careers. The strength of STEM values better predicted a career in STEM than did gender. Finally, women in STEM received the least amount of social …

Corona Ion Deposition: A Novel Non-Contact Method For Drug And Gene Delivery To Living Systems, Niraj Ramachandran

USF Tampa Graduate Theses and Dissertations

Application of corona ions produced in air to B16F10 murine melanoma cells in vitro and in animal models resulted in the transport of molecular therapeutics across the cell membrane. This work presents the development of new methods for drug and gene delivery based upon similar principles as the traditional electrode driven membrane destabilization processes known as electroporation. This was achieved with non-contact corona ion deposition that temporarily increased the permeability of cell membranes.

Interaction of corona charge with biological cells was studied and their potential for molecular delivery was established. Molecular delivery was first demonstrated in vitro using tracer molecules …
