Influences Of Reasoning And Achievement Motivation On Complex Problem Solving In A New Microworld Operationalization, Stephan Bartholdy, Ulrike Kipman

Journal of Global Education and Research

Complex Problem Solving (CPS) can be defined as those psychological processes that enable a person to achieve goals under complex conditions, which are characterized by their complexity, connectivity, dynamics, lack of transparency, and polytely. Although many hypothesized influences have previously been tested concerning their relevance for the process of solving complex problems (e.g., general intelligence), results were often found to be rather heterogeneous. As this was found to be partially caused by fundamental differences between measurements of CPS, a new operationalization was used in the present study: Following the Microworld approach, CPS was assessed in the simulation game Cities: Skylines …

Development Of A Voxel-Based Monte Carlo Radiation Dosimetry Methodology For A Targeted Alpha Particle Therapy, Christopher John Tichacek

USF Tampa Graduate Theses and Dissertations

The use of targeted ligands to deliver radioisotopes directly to tumor cells is a promising therapeutic strategy. Because of the short path length and high LET of alpha particles, targeted alpha particles are ideal for treating metastatic disease while minimizing damage to non-targeted tissues. However, clinical methods for determining 3D radiation dosimetry in patients with multiple metastatic lesions are needed to support clinical translation of novel targeted alpha particle therapies for personalized treatment, especially in patients that have previously received radiotherapy. Recently interest in novel radiopharmaceutical development has grown significantly. However, compared to external beam radiation therapy, progress in customizing …

USF Tampa Graduate Theses and Dissertations

Hearing loss due to exposure to high level sound is a major health problem that causes permanent hearing impairment and has a significant impact on job productivity and quality of life. A large population suffers from noise-induced hearing loss (NIHL), a disorder for which there is currently no FDA-approved prevention, treatment or cure. The goal of my dissertation work is to provide insights into the effects of noise trauma on hearing abilities of normal hearing subjects, and determine how a new therapeutic compound (mGlu7 modulator) can protect and/or prevent loss of, or damage to sensory cells and brain neurons, including …

Amyloid Protein Aggregation And Associated Toxicity, Chamani A. Niyangoda

USF Tampa Graduate Theses and Dissertations

Amyloidosis is a group of diseases in which amyloid fibrils accumulate and deposit into plaques and intracellular inclusions which lead to disruption of the tissue architecture and function. Most of the amyloid diseases are incurable due to a lack of understanding of the amyloid formation, as well as associated toxicity. My research work is focused on three different aspects of amyloid aggregation.

The aim of the first project is to investigate the potential use of deep-blue autofluorescence (dbAF) as an intrinsic optical probe to study amyloid self-assembly. This novel fluorescence signal is excited at the long wavelength edge of the …

Thermoelectric phenomena have been observed for the past two centuries while still being an interesting source of new research because of the countless unknowns governing thermoelectric transport in a host of materials. Novel materials and material structures continue to be discovered, providing enhanced thermoelectric effects that can be used in thermoelectric devices for power generation and refrigeration. With the increasing demand for reusable and renewable energy sources, the importance and usefulness of thermoelectric phenomena grows. It is therefore important to understand thermoelectric transport on both the larger macroscale of devices that serve to define material properties and the smaller microscale …

Educators' Perceptions Of Students' Academic And Social Growth In A Collegiate High School Program., John Matthew Legg

USF Tampa Graduate Theses and Dissertations

The purpose of this research was to examine educators’ perceptions of high school students’ academic and social growth in a collegiate college program. Collegiate high school programs afford opportunities to minorities and the economically disadvantaged, as well as first-generation college students (Aviles-Reyes, 2007). This research used a qualitative case study framework to collect information about educators’ perceptions of the academic and social integration of students in a collegiate college program. Data were collected in phases—educator focus group interviews and individual interviews—and subsequently coded and reviewed using thematic comparative analysis. The guiding question was as follows: What are educators’ perceptions of …

Education In The Settler Colony: Displacement, Inequality, And Disappearance Via Charter Schools, David R. Fisher

USF Tampa Graduate Theses and Dissertations

The encroachment of market-based practices on public education has resulted in the creation of vouchers, charter schools, virtual schools, home schools, and other forms of educational choice. While there has always been choice in education in the United States for the wealthy and White, the current conception of school choice, in theory, allows equal access to education for all. Undergirding the neoliberal practice of school choice is a connection to a troubling past of capitalist oppression and settler colonialism. Like settler colonialism, the practice of school choice has resulted in the displacement of educators, families, and students, inequality between different …

Disciplinary D/Discourses: Navigating And Negotiating Disciplinary Paradigms, Michael R. P. Bailey

USF Tampa Graduate Theses and Dissertations

Over the past twenty-five years, in the United States, zero-tolerance policies that were initially implemented to deter gun violence and drugs in schools have expanded to include a wide range of discretionary offenses such as disrespect and defiance. As a result, many students have been denied access to educational opportunities, been excluded from their peers, and had their lives irrevocably changed due to systemic sanctioning of exclusionary practices. Educators, who are caught between competing societal demands, job expectations, and ethical beliefs about their profession are tasked with balancing the instructional and interactional components of their work in an attempt to …

Health-Promoting Behaviors And Subjective Well-Being Among High School Students, Nicholas David W. Smith

USF Tampa Graduate Theses and Dissertations

In positive psychology, a greater emphasis is placed on the presence of indicators of both physical and mental health. This study examined the relationship between 12 health-promoting behaviors and subjective well-being (SWB; e.g., happiness) in a sample of 450 high school aged youth from five high schools in two states. Participants reported on their dietary habits, physical activity, abstinence from tobacco products, abstinence from alcohol, and sleep hygiene (i.e., 8 unique components) as well as a multidimensional assessment of SWB (i.e., life satisfaction, positive affect, and negative affect). It was hypothesized that increased engagement in each of the health-promoting behaviors …

My findings indicated that the study participants’ experiences such as positive interactions with faculty …

Building A Collaborative Culture In A Middle School: A Case Study, Andrew Olson

USF Tampa Graduate Theses and Dissertations

There is extensive research indicating the importance of teachers working together in teams and in conjunction with school leadership to improve teaching practice and, ultimately, outcomes for students. However, there is little evidence that collaboration is valued in the American school system. Tension pervades in a system that often prescribes a top-down approach to teacher evaluation, fails to provide sufficient time for teachers to collaborate, and unfairly scapegoats teachers for many challenges both within society and the education system itself. It is not surprising that teachers are leaving the profession at an alarming rate.

Combine these contextual factors with the …

Formulation To Application: Thermomechanical Characterization Of Flexible Polyimides And The Improvement Of Their Properties Via Chain Interaction, Alejandro Rivera Nicholls

USF Tampa Graduate Theses and Dissertations

In this work, Polyimides were synthesized by incorporating an aromatic diamine monomer with a methylene linker, 4,4'-methylenebis(2,6-dimethylaniline) (MBDMA), to make a robust main chain along with aliphatic polyetherdiamine backbone linkers to reduce rigidity. The polymers were designed to exhibit thermal properties in between those of conventional aromatic polyimides and polymers with wholly aliphatic ether diamine links. Through dynamic mechanical analysis and differential scanning calorimetry, it is shown that control of the molar ratios of the aromatic MBDMA and the composition and size of the aliphatic polyetherdiamine can be used to tune the glass transition temperature. The materials were characterized and …

An Autobiographical Narrative Of A Principal's Personal Journey With Autonomy, Delilah Rabeiro

USF Tampa Graduate Theses and Dissertations

Educational reform and state policies have stripped principals and teachers of autonomy, and this has been attributed as one of the reasons why teachers leave the profession. Adamson (2012) stated, "To implement reform at their school sites, principals need a certain degree of autonomy. This study sought to understand what I experienced of autonomy as I embarked on my journey as a principal of a turnaround school; what I did, or did not do, to extend autonomy to teachers; and what I came understand about autonomy in this turnaround setting.

This was an autobiographical narrative inquiry (Freeman, 2007; Saleh, Menon, …

Evaluating Conversation Agent Impact On Student Experience In A Distance Education Course, Grover Walters

USF Tampa Graduate Theses and Dissertations

We explore the efficacy of conversation agents operating as an instructional aid in a distance education course. Two aspects of efficacy are considered—conversation agent impact on student perceptions of the experience, and how different design features of the agent affect student perceptions of engagement. Evaluation of the agent is accomplished by collecting data from 24 undergraduate participants separated into random groups. We conduct two rounds of mixedmethod evaluation. Between the two rounds, a modification to the agent occurs based on the outcome of the first evaluation. Findings include limitations related to phrasing and data persistence features of the design that …

Simulation And Experimental Investigation Of Fluid Mixing Enhancement With Orifice Plate, Mohammed Al Busaidi

USF Tampa Graduate Theses and Dissertations

Current experimental and simulation fluid mixing studies aim to increase mixing efficiency and incorporate various measurement methods to quantify mixing. In this thesis, comprehensive simulation and experimental studies were carried out to investigate the effects of an orifice plate on mixing. Mixing efficiency is measured through the correlation of volume fraction to color light reflectivity, as dyes were introduced to the fluids being mixed. Volume fractions close to 0.5 indicate high mixing performance, and the efficiency declines as volume fractions depart from 0.5. It was found that fluids in a small diameter tube do not mix due to the absence …

Measuring And Utilizing High-Dimensional Information Of Optical Fields, Ziyi Zhu

USF Tampa Graduate Theses and Dissertations

Currently, many areas of optical techniques including imaging, inspection and communication emphasize the utilization of the high-dimensional information encoded in optical fields. There is also a requirement for novel measurement techniques to extract this high-dimensional information with high-speed and accuracy. We firstly introduce a scan-free direct measurement technique that is capable of simultaneously characterizing the amplitude and phase of a coherent scalar optical field. Our direct measurement approach is constituted of a weak polarization perturbation which is followed by the recording of a polarization-resolving imaging process. The weak perturbation rotates the linear polarization on the spatial frequency domain of the …

Digital Corpus Use In Learning L2 Prepositional Collocations: A Pilot Study, Matthew A. Siegel

USF Tampa Graduate Theses and Dissertations

Because of their prevalence in both spoken and written English, collocations—words that go together—are important for the English language learner. Collocations that contain prepositions have been shown to pose particular difficulty (Hong, Rahim, Hua, & Salehuddin, 2011). Collocational errors are common, even among advanced learners (Laufer & Waldman, 2011). The purpose of this pilot study was three-fold: (1) to determine whether the use of a digital corpus by English language learners is effective in learning prepositional collocations, (2) to determine if proficiency level exerts any influence on effectiveness of using a digital corpus to learn prepositional collocations, and (3) to …

Ripping The “Paper Ceiling”: How Social Studies Teachers Conceive And Enact The Integration Of Gender And Women’S Experiences In Their Curriculum, Andrea Watson-Canning

USF Tampa Graduate Theses and Dissertations

The purpose of this dissertation is to explore the intentions of teachers who report incorporating gender and women’s experiences into their social studies curriculum and how those intentions are manifested in the classroom. I examine how teachers talk about the purposes of social studies education, their reasons for incorporating gender and women’s experiences into their curriculum, and their descriptions of incorporation (the intended curriculum). Then, I analyze how the intended curriculum is enacted in the classroom.

Using educational connoisseurship and criticism and portraiture, I construct narrative portraits of the phenomena analyzed. Both educational connoisseurship and criticism and portraiture consider the …

Roma Girls Expressing Identity, Aspirations, And Voice Through Participatory Arts-Based Research, Crista Kaye Banks

USF Tampa Graduate Theses and Dissertations

The methods by which Roma girls are studied and represented, do not account for their individual expressions of identity, aspirations or voice. Experiences and voices of Roma girls have rarely been seen or heard and have been consistently defined and represented by non-Roma individuals throughout history and within academia, which has perpetuated stereotypes. Interpretations of the image and lives of the Romani are permeated with misperceptions, myths, and assumptions based on stereotypical definitions.

This study uses the arts-based method of mixed media collage with Roma girls in London, England, to understand their expressions of identity, aspirations, and voice. This arts-based, …

International Teaching Assistants’ Perceptions Of English And Spanish Language Use At The University Of Puerto Rico-Mayagüez, Edward G. Contreras Santiago

USF Tampa Graduate Theses and Dissertations

Globalization and sociopolitical factors impact migration patterns all over the world. In Puerto Rico, these factors created superdiverse environments where languages users have pushed the boundaries of language in order to make sense of their worlds. Even though this language dynamic is natural for locals, it is those who visit from different countries, specifically international graduate students, that have a difficult time adjusting to Puerto Rico’s rich use of English and Spanish. Understanding how international graduate students perceive the language used at the University of Puerto Rico, Mayagüez (UPRM) upon arrival is essential to provide a better experience for future …

An Investigation Of The Effects Of The Parasitic Nematode Aplectana Hamatospicula On The Performance And Behavior Of Cuban Treefrogs (Osteopilus Septentrionalis), Kerri Surbaugh

USF Tampa Graduate Theses and Dissertations

Parasitic infections are ubiquitous in nature, and host-parasite dynamics can have powerful effects on wildlife populations. Many species have evolved behavioral responses to infection that can help mitigate damage from parasites. Anorexia is a common response to infection observed throughout the animal kingdom. Reducing nutrient intake can help shift host resources from digestion to immunity, as well as limit resources available to parasites. Reduced feeding can weaken the host, but in some host-parasite interactions, this cost is less than that of maintaining an infection. Here, I describe an experiment aimed to explore the effects of the parasitic nematode Aplectana hamatospicula …
