Visualization Dynamics And Ideal L2 Self: Exploring L2 Learner Motivation In A Study Abroad Context, Dan Zhong
USF Tampa Graduate Theses and Dissertations
Second language learner motivation research has witnessed a transition from a historically static approach to a more dynamic approach, yielding extensive research during the past decade. Dörnyei (2005, 2009) proposed a vigorous motivation framework, the Second Language Motivational Self System (L2MSS) that highlights the dynamic nature of learner motivation. The L2MSS consists of three main constructs: the ideal L2 self, the ought-to L2 self, and the learning experiences (Dörnyei, 2005). This study uses the L2MSS framework as the theoretical basis to explore learners’ motivation and learning experiences in a study abroad context. Empirical studies using this framework to explore L2 …

Isolation Of Specific Phospholipids From Nannochloropsis Oculata Microalga For Cosmetic Applications, Ahmet Yener Manisali
USF Tampa Graduate Theses and Dissertations
Algae, photosynthetic aquatic organisms, have recently caught the attention of the food, cosmetic, pharmaceutical, and nutraceutical industries due to the variety of natural compounds in their cellular bodies such as carbohydrates, lipids, and proteins. Specifically, microalgae-derived natural compounds such as phospholipids are extensively utilized in cosmetics as part of liposome formers, emulsifiers, solubilizers, and wetting agents. Although phospholipids are currently extracted from food sources, this practice raises sustainability concerns. Hence, growing microalgae on the provision of macronutrients such as nitrates and phosphates will serve as a more sustainable source of the several specific phospholipids such as phosphatidylcholine (PC), phosphatidyl-ethanolamine (PE), …

Exploring Adult Indigenous Latinxs’ English Language Identity Expressions And Agency: A Malp®-Informed Photovoice Study, Andrea Enikő Lypka
USF Tampa Graduate Theses and Dissertations
Scholars historically emphasized literate learners’ additional language trajectories. In countries with increasingly large numbers of limited-literate adult language learners, there is an urgent need to inspire limited-literate adults to speak out and be heard. To address the needs of adult language learners with inconsistent schooling, and the ways their identities, agency, and social power influence opportunities for participation in the target language communities of practice, scholars need to implement bottom-up and responsive curricular and research innovations. To this end, informed by poststructuralist and transdisciplinary understandings of English language development, I investigated the identity work (self-positioning and other-positioning) and agency deployment …

Laser-Induced Modifications In Two-Dimensional Materials, Tariq Afaneh
USF Tampa Graduate Theses and Dissertations
Atomically thin two-dimensional (2D) materials have attracted a growing interest in the lastdecade from the fundamental point of view as well as their potential applications in functional devices. Due to their high surface-to-volume ratio, the physical properties of 2D materials are very sensitive to the environmental factor such as surrounding media and illumination conditions (e.g. light-mater interaction). In the first part of this dissertation I will present recent advances in developing laser-assisted methods to tune the physical properties of 2D transition metal dichalcogenides (TMDs). We demonstrate laser-assisted chemical modification ultrathin TMDs, locally replacing selenium by sulfur atoms. The photo-conversion process …

Controlling Properties Of Light: Metamaterials Design And Methodology, Darrick Hay
USF Tampa Graduate Theses and Dissertations
Electromagnetic metamaterials are materials that have designed electromagnetic properties. In general metamaterials are subwavelength and can be treated as homogeneous media with an effective permittivity and permeability. Early metamaterial designs were developed to exhibit electromagnetic responses not typically found in naturally occuring materials, but this is not a strict requirement. Metamaterials have shown promise for applications throughout the electromagnetic spectrum. The goal of this work is to present a coherent methodology for metamaterials design, fabrication and application while also describing all of the relevant physics of the designed metamaterials.
Chapter 1 is comprised of an introduction into the field of …

Origins Of Amyloid Oligomers And Novel Approaches For Their Detection, Jeremy Barton
USF Tampa Graduate Theses and Dissertations
Alzheimer’s disease, type II diabetes, and other amyloid diseases are known to be associated with the formation of amyloid aggregates. It has been thoroughly researched whether amyloid fibrils or oligomers are the main culprit for these diseases, and recent evidence has connected oligomers as the most disease relevant aggregate species. However, many difficulties have arose in confirming this hypothesis. Techniques for oligomer detection are often limited in their sensitivity, and in many cases are unable to distinguish oligomers from rigid fibrils. Additionally, the role oligomer splay in fibril assembly is still unclear, and has led to the belief that different …

"In recent years, innovation, entrepreneurship, and globalization have become popular concepts in relation to technology design. While some major corporations and other entities continue pushing for globalization through the design and dissemination of digital technologies, researchers also caution against the biases and oppression that can be embedded in US culture’s 'near-ubiquitous use of algorithmically driven software.'1 Countering some previously established orientations to globalization and entrepreneurship, this chapter highlights the importance of building technological innovation with (rather than just for or about) historically, structurally, and systematically marginalized and underrepresented communities. The overall purpose of this chapter is to showcase how …

Career And Technical Education Teachers’ Beliefs About Developing Students’ Motivation To Write, Katie Graham
College of Education and Human Sciences: Dissertations, Theses, and Student Research
Students in the U.S. write poorly. Although postsecondary and workplace writing expectations continue to rise, writing instruction has largely remained unchanged over time. As a result, student writing outcomes continue to fall below expectations from both an assessment and hirable proficiency standpoint. Career and Technical Education (CTE) provides a unique opportunity to motivate students who are otherwise disengaged in writing (ACTE, 2009). The benefits of helping students develop their writing-self efficacy has well-documented support (Bruning & Horn, 2009; Bandura, 1997; Pajares 2003; Pajares & Valiante, 2006). However, little is known about the writing opportunities provided in CTE classes or CTE …
