Constraining Basin Geometry And Fault Kinematics On The Santo Tomás Segment Of The Agua Blanca Fault Through A Combined Geophysical And Structural Study, Adam Springer Jan 2010

Constraining Basin Geometry And Fault Kinematics On The Santo Tomás Segment Of The Agua Blanca Fault Through A Combined Geophysical And Structural Study, Adam Springer

USF Tampa Graduate Theses and Dissertations

The Agua Blanca fault is a major transverse structure of northern Baja California, extending more than 120km east from the Punta Banda ridge near the city of Ensenada to the San Matais Pass in central Baja. Through much of its eastern extent slip on this fault appears to be pure strike slip, however, at the Valle de Santo Tomás the fault makes a ~25°; change in orientation, which coincides with the formation of extensional basins on the fault. Recent evidence of the independent movement of the Baja Micro-plate relative to a stable Southern California Black leads to several possible hypotheses …


Magnetocaloric Effect In Thin Films And Heterostructures, Christopher Bauer Jan 2010

Magnetocaloric Effect In Thin Films And Heterostructures, Christopher Bauer

USF Tampa Graduate Theses and Dissertations

The goals of this work are the optimization of the magnetocaloric effect in Gadolinium thin film structures. We approach this issue from two directions, that of process optimization and of interface effects. Past results showed Gd2O3 in our Gadolinium thin films, and the presence of such oxide seemed to grow with the temperature at which the film was grown or annealed. Comparison of samples grown without chamber gettering to those that were gettered show differences in their structural and magnetic properties, and we conclude that gettering is an effective step in enhancing the quality of Gd thin …

Saving Energy In Network Hosts With An Application Layer Proxy: Design And Evaluation Of New Methods That Utilize Improved Bloom Filters, Miguel Jimeno

USF Tampa Graduate Theses and Dissertations

One of the most urgent challenges of the 21st century is to investigate new technologies that can enable a transition towards a society with a reduced CO2 footprint. Information Technology generates about 2% of the global CO2, which is comparable to the aviation industry. Being connected to the Internet requires active participation in responding to protocol messages. Billions of dollars worth of electricity every year are used to keep network hosts fully powered-on at all times only for the purpose of maintaining network presence. Most network hosts are idle most of the time, thus presenting a huge …


Synthesis Of Local Thermo-Physical Models Using Genetic Programming, Ying Zhang Dec 2009

Synthesis Of Local Thermo-Physical Models Using Genetic Programming, Ying Zhang

USF Tampa Graduate Theses and Dissertations

Local thermodynamic models are practical alternatives to computationally expensive rigorous models that involve implicit computational procedures and often complement them to accelerate computation for real-time optimization and control. Human-centered strategies for development of these models are based on approximation of theoretical models. Genetic Programming (GP) system can extract knowledge from the given data in the form of symbolic expressions. This research describes a fully data driven automatic self-evolving algorithm that builds appropriate approximating formulae for local models using genetic programming. No a-priori information on the type of mixture (ideal/non ideal etc.) or assumptions are necessary.

The approach involves synthesis of …


Filtration Performance Of A Niosh-Approved N95 Filtering Facepiece Respirator With Stapled Head Straps, Daniel E. Medina Dec 2009

Filtration Performance Of A Niosh-Approved N95 Filtering Facepiece Respirator With Stapled Head Straps, Daniel E. Medina

USF Tampa Graduate Theses and Dissertations

Certain models of NIOSH-approved filtering facepiece air purifying respirators are manufactured with stapled head straps. Depending on the manufacturer, these head straps may be stapled to the filter media itself. This may cause leakage through the filter media of the respirator, potentially exposing the user to an unacceptable level of contaminant. In this study, monodisperse polystyrene latex (PSL) spheres were generated to challenge four replicates of a N95 single use respirator model made by the same manufacturer.

Nominal particle sizes of the PSL spheres used to challenge the respirators were 0.5, 1, and 2 micrometers in diameter. All respirators were …


A Program Evaluation Of A Literacy Initiative For Students With Moderate To Severe Disabilities, Carrie F. De La Cruz Dec 2009

A Program Evaluation Of A Literacy Initiative For Students With Moderate To Severe Disabilities, Carrie F. De La Cruz

USF Tampa Graduate Theses and Dissertations

Recently the National Reading Panel concluded that systematic and direct instruction in phonological awareness, phonics, fluency, vocabulary, and comprehension that is informed by ongoing assessments of student progress results in positive student achievement (NICHHD, 2002). For students with moderate to severe disabilities and students with autism, reading instruction has historically focused on functional sight words. Unfortunately, very little research exists that has examined how the literacy achievement of students with moderate to severe disabilities can be impacted by a more comprehensive, data-driven instructional model.

A special education program that serves students with moderate to severe disabilities and students with autism …


Addressing The Problem Of Land Motion At Tide Gauges, Kara J. Doran Nov 2009

Addressing The Problem Of Land Motion At Tide Gauges, Kara J. Doran

USF Tampa Graduate Theses and Dissertations

Estimation of global mean sea level change has become an area of interest for scientists in recent decades because of its importance as an indicator of climate change. Climate models predict varying degrees of change in global temperature and global sea level over the next 100 years. One way to check the validity of the models is to estimate sea level change over the last century and constrain the models to match these estimates. Traditionally, sea level change estimates have been calculated using long time series from tide gauges. There are some disadvantages to this approach however, since tide gauges …


The Effect Of Stress On Hedonic Capacity In Generalized Anxiety Disorder: A Prospective Experimental Study Of One Potential Pathway To Depression, Bethany H. Morris Nov 2009

The Effect Of Stress On Hedonic Capacity In Generalized Anxiety Disorder: A Prospective Experimental Study Of One Potential Pathway To Depression, Bethany H. Morris

USF Tampa Graduate Theses and Dissertations

A growing body of work links psychopathology to changes in hedonic capacity following stressors. This was the first experimental study of the effects of stress on hedonic capacity in an analog generalized anxiety disorder (GAD) sample (a high worry group). Specifically, we utilized an experimental manipulation of stress and a behavioral index of anhedonia to test the hypothesis that individuals with GAD, who are at higher risk for developing depression symptoms, exhibit greater stress-related deficits in hedonic capacity than do nonanxious controls. Further, this study assessed whether stress-induced hedonic deficits predicted future depression. Controls exhibited the expected reward learning pattern …


Dyna-Mod Constructing The Modern Adaptable Home, Sarah Deardorff Nov 2009

Dyna-Mod Constructing The Modern Adaptable Home, Sarah Deardorff

USF Tampa Graduate Theses and Dissertations

The modern home has become a static fixture in society that is not reflected in the growing populous that is becoming an ever increasing mobile society. Many are not able to stay to the same place that they call home for long periods of time. Changing jobs, markets and neighborhoods force those to continue their movement around leaving what it is that they call their home to try and reproduce it within another location. The home finds itself lost in this transition and must now function on a greater adaptability than ever before and reflect the growing demand placed upon …


The Politics Of Space And Place In Virginia Woolf’S The Years, Three Guineas And The Pargiters, Ángel Luis Jiménez Nov 2009

The Politics Of Space And Place In Virginia Woolf’S The Years, Three Guineas And The Pargiters, Ángel Luis Jiménez

USF Tampa Graduate Theses and Dissertations

A critique of the social construction of space was fundamental to Virginia Woolf's overall feminist project of decentering patriarchal and imperial values. In A Room of One's Own (1929) Woolf famously emphasized that financial independence and a private space were vital to female creativity. But Woolf was concerned with the politics of space throughout her writing, an aspect of her thought that has not been widely addressed. My thesis examines Woolf's ongoing preoccupation with spatiality in two closely related works of her late career, The Years (1937) and Three Guineas (1938). In these texts, Woolf interrogates the cultural construction of …

Defining A Community: Controlling Nuisance In Late-Medieval London, Natalie J. Ciecieznski

USF Tampa Graduate Theses and Dissertations

Using municipal sources from late medieval London, this study examines nuisance as a sub-topic of social regulation. In addition to defining nuisance, it analyzes who controlled nuisance and how it was controlled from the late thirteenth through the early fifteenth centuries. During this period, nuisance comprised building and boundary disputes between neighbors, such as conveying rainwater onto a neighboring property instead of to the street; environmental issues, such as blocking passageways with rubbish and not properly disposing of waste; certain groups of people and places, such as vagrants and brothels; and certain forms of speech, such as insults and threats. …


True North Or Traveled Terrain? An Empirical Investigation Of Authentic Leadership, Matthew D. Tuttle Nov 2009

True North Or Traveled Terrain? An Empirical Investigation Of Authentic Leadership, Matthew D. Tuttle

USF Tampa Graduate Theses and Dissertations

Authentic leadership is a new concept that is gaining both popularity and notoriety in the leadership literature. It is argued as a positive form of leadership that goes beyond traditional leadership styles in order to influence followers through genuine, ethical behavior. However, as a concept in its infancy, authentic leadership has yet to receive much empirical attention, and many researchers are skeptical of its value in what is seen as a saturated domain of leadership styles. This study offers a comprehensive approach to addressing this need. A new measure for authentic leadership was developed and validated through pilot testing. Through …

Training Teamwork In Medical Teams: An Active Approach With Role Play And Feedback, Matthew S. Prewett

USF Tampa Graduate Theses and Dissertations

Recent reports in the field of medicine have recommended the use of teamwork training to reduce the number of injuries and fatalities from human error. Teamwork training in the field of medicine appears promising, but few empirical evaluations of such programs have confirmed their effectiveness. Existing teamwork training studies have tended to use a traditional, lecture approach to training, with positive but modest results upon teamwork attitudes and behaviors. The current study developed and evaluated a more active teamwork training protocol for trauma resuscitation teams. The training protocol supplemented several medical and non-medical role plays with a lecture and guided …


An Assessment Of A Naturalistic In-Home Training Protocol To Establish Joint Attention Responding With Children Diagnosed With Autism Spectrum Disorders, Heather Burris Nov 2009

An Assessment Of A Naturalistic In-Home Training Protocol To Establish Joint Attention Responding With Children Diagnosed With Autism Spectrum Disorders, Heather Burris

USF Tampa Graduate Theses and Dissertations

Children with autism have deficits in social interactions and verbal and nonverbal communication and engagement in rigid and repetitive activities and/or interests (ASA, 2008). A joint attention (JA) repertoire has been identified as a behavioral cusp for later social development and thus, JA deficits serve as an early indicator for diagnosis of autism spectrum disorder (Vismara & Lyons, 2007; Whalen & Schbreibman, 2003). A JA repertoire consists of both responses to- and initiations for-bids for coordinated attention. Previous research has shown teaching strategies such as pivotal response and discrete trial training for joint attention skills to be effective (Vismara & …

The three unfolding conditions used in this work are high-temperature, low temperature and low pH. The folding of this protein has been extensively studied experimentally, providing a large data base of folding parameters which can be probed using simulations.

The crystal structure of sperm whale myoglobin was taken from Protein Data Bank, followed by the removal of the heme unit and a subsequent energy minimization was performed in order to generate the native apomyoblogin form. Thus, the …


Gender And Internal Migration In Wuhan, Hubei Province, China: Rural Hometowns, Factory Work, And Urban Experiences, Milena Urszula Janiec-Grygo Nov 2009

Gender And Internal Migration In Wuhan, Hubei Province, China: Rural Hometowns, Factory Work, And Urban Experiences, Milena Urszula Janiec-Grygo

USF Tampa Graduate Theses and Dissertations

This thesis focuses on gender and scale as key aspects of the rural-to-urban migration process in China. Its specific aim is to connect economic and social reasons for rural women's migration towards urban factory work. Contemporary large-scale migration studies show inconsistencies and contradictions concerning reasons for migration, especially as it relates to gender. Thus, migration research often emphasizes the positive social changes experienced by women workers, in effect signaling that the most important needs of women migrants can be satisfied without economic gains. In contrast, the proposed study seeks to show that social and economic reasons intertwine within women's experiences …
