Minimal And Symmetric Global Partition Polynomials For Reproducing Kernel Elements, Mario Jesus Juha

USF Tampa Graduate Theses and Dissertations

The Reproducing Kernel Element Method is a numerical technique that combines finite element and meshless methods to construct shape functions of arbitrary order and continuity, yet retains the Kronecker-δ property. Central to constructing these shape functions is the construction of global partition polynomials on an element. This dissertation shows that asymmetric interpolations may arise due to such things as changes in the local to global node numbering and that may adversely affect the interpolation capability of the method. This issue arises due to the use in previous formulations of incomplete polynomials that are subsequently non-affine invariant. This dissertation lays out …

Goal Compatibility And Emotional Intensity: An Experimental Study Of Graphic Images In Strategic Communication, Lauren Marie Klinger

USF Tampa Graduate Theses and Dissertations

The purpose of this quantitative study is to examine receiver variables involved in strategic communications and to look specifically at the use of graphic images in strategic communication materials. It argues that any complete, general model of persuasion effects will include both goal compatibility and emotional determinants. It argues that some influential theories used in strategic communications scholarship, including the situational theory of publics and the elaboration likelihood model, are incomplete because they have omitted these variables. This study also tests variables related to willingness to communicate, behavioral intention, and attitude towards the organization. These variables are drawn from prominent, …

The research questions focused on: (1) the participants' beliefs and attitudes about professional learning conversations, …

Talking With Als Patients: An Exploratory Study Of Patient Attitudes Toward Mass Messages About Als, Kamden Kuhn

USF Tampa Graduate Theses and Dissertations

This study examines the attitudes and opinions of ALS patients toward mass messages about their condition. Six focus groups of ALS patient support groups viewed and responded to public relations messages, charity advertisements, and a news story. Results suggest that mass messages remind participants of the need for public ALS awareness. Participants also said they shared in the narratives and identify closely with the characters in the messages they viewed, and participants expressed concern with disease depictions. These concerns included a tension between positive and realistic portrayals, identification of message inaccuracies, and a desire for more specific disease information. The …

High-Resolution Event Stratigraphy Of Mm-Scale Laminated Sediments From Coastal Salt Ponds: St. John, Us Virgin Islands, Rebekka Amie Larson

USF Tampa Graduate Theses and Dissertations

A multi-proxy approach is utilized on mm- to cm-scale laminated sediment records in coastal salt ponds on St. John, U.S. Virgin Islands to characterize the sediments, identify their sources and depositional processes/events (heavy rainfall, tropical cyclones, tsunamis). Historical records are combined with high-resolution geochronology (short-lived radioisotopes, ²¹⁰Pb, ¹³⁷Cs, ⁷Be) and scanning elemental techniques (XRF and LA-ICP-MS) to link depositional events to how they are manifested in the sedimentary record. Volcanic rocks are the terrigenous sediment source and the sedimentary signature of terrigenous sediment in the geologic record consists of higher amounts of Al, Fe, Ti, Co, and …

Usf's Coverage Of Women's Athletics: A Census Of The Usf Athletics Home Web Page, Laura Ann Lebeau

USF Tampa Graduate Theses and Dissertations

This study examines the coverage of women’s athletics at USF provided through photographic representations on the university’s Athletics Internet home web page during the 2009–2010 academic year. Findings from this census of five areas that comprise the USF Athletics Internet home web page revealed that, consistent with recent research on coverage of female athletes and women’s athletics on university web pages, women, compared to men, were underrepresented in the majority of the five areas of the home page analyzed. The difference in the number of overall total photographs of women and men was not that large—48% and 52%, respectively, not …

Assessment Of The Dependence Of Ventilation Image Calculation From 4d-Ct On Deformation And Ventilation Algorithms, Kujtim Latifi

USF Tampa Graduate Theses and Dissertations

Ventilation imaging using 4D-CT is a convenient and cost effective functional imaging methodology which might be of value in radiotherapy treatment planning to spare functional lung volumes. To calculate ventilation imaging from 4D-CT we must use deformable image registration (DIR). This study validates the DIR methods and investigates the dependence of calculated ventilation on DIR methods and ventilation algorithms.

The first hypothesis is if ventilation algorithms are robust then they will be insensitive to the precise DIR used provided the DIR is accurate. The second hypothesis is that the change in Houndsfield Unit (HU) method is less dependent on the …

The purpose of this thesis was to explore the origins, formulation, course and outcome of the Intergovernmental Committee for Political Refugees meeting (better known as the Evian Conference) of July 1938. Special emphasis was placed on contemporary and later historical assessments of this assembly which represented the first international cooperative attempt to solve an acute refugee crisis. A general review followed by a more detailed evaluation was made of existing official and un-official accounts of the meeting utilizing both public records, private diaries, books, newspapers, journals and other periodicals for the period of January 1, 1938 through December 31, 1939. …

Interpreting With "All Possible Caution, On Mental Tiptoe": Nabakov's Post-Romantic Renewal Of Perception In Lolita, Curtis Donald Le Van

USF Tampa Graduate Theses and Dissertations

Although presenting the concept of love in a form not accepted by societal conventions does indeed estrange the conception of love in Nabakov's Lolita, it does nothing to explain how readers accept Humbert's passion, without immediately and consistently disregarding it as lewd and inappropriate. I will argue that Nabakov estranges the romantic conceptions not by defamiliarizing the occasion of love (i.e. by making the romance a manifestation of pedophilia), but rather by defamiliarizing and complicating the acts of both reading and interpreting. First, I will make associations between the Romantics and Nabokov, regarding their shared desire to renew the habitual …

Rethinking Buffer Operations In A Dual-Store Framework, Melissa Lehman

USF Tampa Graduate Theses and Dissertations

Atkinson and Shiffrin's (1968) dual-store model of memory includes a structural memory store along with control processes conceptualized as a rehearsal buffer. I present a variant of Atkinson and Shiffrin’s buffer model within a global memory framework that accounts for findings previously thought to be difficult for it to explain. This model assumes a limited capacity buffer where information is stored about items, along with information about associations between items and between items and the context in which they are studied. The strength of association between items and context is limited by the number of items simultaneously occupying the buffer. …

Self-Alignment Of Silicon Microparts On A Hexadecane-Water Interface By Surface Tension, Caroline Elizabeth Liberti

USF Tampa Graduate Theses and Dissertations

Mechanical assembly of systems and structures on the micro-scale can be inefficient as particles of sub-millimeter dimensions are difficult to manipulate. Cutting edge manufacturing methods implement self-assembly as an approach to ordering micro and nano-sized parts into a desired arrangement. This thesis studies a technique utilizing surface tension as a method of actuating microparts on a liquid-liquid interface via lateral capillary interactions. Preliminary experimentation is conducted to investigate the feasibility of developing a new method for self-alignment of microparts by observing the influence of interfacial geometry on the movement of silicon tiles along a hexadecanewater interface. Different surface geometries are …

Evaluating The Effects Of Beach Nourishment On Loggerhead Sea Turtle (Caretta Caretta) Nesting In Pinellas County, Florida, Corey R. Leonard Ozan

USF Tampa Graduate Theses and Dissertations

The health of Florida's beaches are vital to the survival of loggerhead sea turtles (Caretta caretta), as nearly half of the world's loggerheads nest on the states beaches. Many of the beaches utilized by the turtles have undergone nourishment projects in hopes of combating erosion of the shoreline, protecting beachfront property, and creating more suitable beaches for tourism. Although it is argued that beach nourishment benefits sea turtles by providing more nesting habitat, the effects of the Pinellas County nourishment projects on loggerhead nesting are unknown. Beach nourishment can alter the compaction, moisture content, and temperature of the sand, all …

Bone Marrow Transplant Nurses' Attitudes About Caring For Patients Who Are Near The End Of Life: A Quality Improvement Project, Leslie Lauersdorf

USF Tampa Graduate Theses and Dissertations

In oncology setting, there is a range of emotions felt by patients and nurses alike such as helplessness, anger, sadness and anxiety; and this is especially the case as patients near the end of life. The literature shows there is an interest in nurses' attitudes toward caring for patients who are near the end of life. This project examines the overall attitude of Bone Marrow Transplant (BMT) nurses' attitudes toward caring for patients who are near the end of life using the Frommelt Attitudes Toward Care of the Dying Scale (FATCOD) and a Demographic Data Sheet. This project investigated the …

Responding To Tobacco Craving: Acceptance Versus Suppression, Erika B. Litvin

USF Tampa Graduate Theses and Dissertations

Most treatments for substance use disorders (SUDs) are based on a model that craving is a primary cause of relapse, and therefore they emphasize skills for preventing and reducing craving. Acceptance and Commitment Therapy (ACT) provides a theoretical rationale for "acceptance" of drug-related thoughts and cravings, and proscribes suppression, a more intuitive and commonly used coping strategy. However, it remains largely unknown whether various coping strategies differentially affect craving intensity, drug use behavior, or other relevant outcomes during a craving episode. Using a randomized, between-subjects design (acceptance-based coping, suppression-based coping, or no coping instructions/control), the current study compared the effect …

That Is Bad! This Is Good: Morality As Constructed By Viewers Of Television Reality Programs, Joseph Charles Losasso

USF Tampa Graduate Theses and Dissertations

Reality shows that feature people going about their presumed daily lives are not base entertainment. Internet message boards about reality programs are sites where moral work happens. Viewers write about the appearance and actions of show characters and construct moral lessons. Through naturally occurring data produced by fans of these shows, I find that viewers generally express a traditional heteronormative morality around class and gender through stating moral lessons, explaining what is wrong with the characters, or through ridicule and praise.

Device Physics Of Solution Processable Solar Cells, Jason Erik Lewis

USF Tampa Graduate Theses and Dissertations

This Ph.D work reports the studies of photovoltaic devices produced by solution processable methods. Two material systems are of interest: one is based on organic semiconductors, and another on organic/inorganic hybrid composites. Specifically, organic photovoltaic (OPV) devices are made using photoactive materials consisted of a p-conjugated polymer [Poly(3-hexylthiophene), or P3HT] and fullerene derivative [phenyl-C60-butric acid methyl ester, or PCBM] in a bulk heterojunction (BHJ) structure of donor/acceptor network. On the other hand, hybrid photovoltaic (HPV) devices are made from blend of quantum dots and p-conjugated polymers. The QD material presented here are of the lead sulfide (PbS), and lead selenide …

Road-Based Landscape Metrics For Quantifying Habitat Fragmentation, Rebecca Whitehead Loraamm

USF Tampa Graduate Theses and Dissertations

Landscape metrics measure the composition and configuration of habitats within landscapes; often the goal is to measure fragmentation. While a variety of existing metrics characterize the connectivity and contiguity of habitat patches, most do not explicitly consider the fragmenting effects of roads in their formulations. This research develops a set of new landscape metrics that explicitly quantify how roads disconnect and break apart habitat patches. This research introduces the following four metrics to consider the fragmenting effects of transportation networks: (1) Number of Connected Patches, a measure of connectivity; (2) Euclidean Nearest Neighbor-Roads, a measure of proximity; (3) Road Density, …
