Data-Driven Modeling Of The Causes And Effects Of Interneuronal Dysfunction In Alzheimer’S Disease And Dravet Syndrome, Carlos Perez

USF Tampa Graduate Theses and Dissertations

One of the defining features of Alzheimer’s disease (AD) is the increased cleavage of the amyloid precursor protein (APP), causing abnormally high levels of the aggregation form of amyloid beta (Aβ ). Many studies have shown that both AD patients and AD mice models exhibit abnormal network activity, including hypersynchronous excitatory neuron behavior, altered brain rhythms, and in some instances epileptic seizures when exposed to high levels of Aβ In particular, strong experimental evidence suggests that it is the small globular amyloid oligomers (gOs) and curvilinear fibrils (CFs) rather than the more stable, late stage rigid fibrils (RFs) that cause …

Counseling Clients With Traumatic Brain Injury: Exploring Counselors’ Perceived Knowledge, Comfort, And Self-Awareness, Michelle Bradham-Cousar

USF Tampa Graduate Theses and Dissertations

The number of traumatic brain injury (TBI) diagnoses continues to rise each year. Counseling is a critical factor in TBI treatment, and although numerous studies have investigated TBI outcomes, a paucity of researchers have studied professional counselors’ knowledge, comfort, and self-awareness when working with TBI clients. Due to the diversity of counselor caseloads, it is likely that counselors will serve clients with a dual diagnosis that includes TBI. These dual diagnoses include depression, posttraumatic stress disorder, anxiety, psychosis, or another neurocognitive disorder. The purpose of this study was to explore counselors’ knowledge, comfort, and self-awareness when working with individuals with …

Second, it researched the effectiveness of explicit metacognitive instruction accompanied with an e-learning environment in enhancing the …

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), …

The Convergence Of Our American And Ghanaian Lives: A Narrative Inquiry, Hope Marie Zikpi

USF Tampa Graduate Theses and Dissertations

There is little in the body of literature about the experience of orphans and vulnerable children (OVC) in Ghana from their perspectives.

Mapping Narrative Transactions: A Method/Framework For Exploring Multimodal Documents As Social Semiotic Sites For Ethnographic Study, Anne W. Anderson

USF Tampa Graduate Theses and Dissertations

This work grew from my attempts to find a method for studying a body of editorial cartoons—multi-modal documents producing cross-modal responses—that were created and published in an earlier time period, in order to answer questions about the culture in which the cartoons were produced and read. Initially my questions included wondering about the topics cartoonists addressed, the narratives cartoonists created to address the topics, how the narratives were framed, and in what ways the narratives might have been seen as attempts to shape the larger cultural discourse around the topics. However, given the number of possible combinations of information streams …

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 …

Collective Teacher-Researcher Inquiry: Localizing School-Based Curriculum Development In Diversified Hong Kong Schooling Contexts, Zheng Zhang, Sally Wai-Yan Wan, Lai Ha Chan, Pui-Ying Lorelei Kwan, Lai-Ling Sandy Tam, Eunice Wai-Po Wan

Journal of Practitioner Research

Responding to a recent call for turning a focus on advancing practices in curriculum studies, this paper reports collective memory work that disrupted academics’ hegemonic voices in School-Based Curriculum Development (SBCD) studies and elicited teachers’ stories about their school-based curriculum development (SBCD) practices. With post-colonialism as the theoretical underpinning, we explored how the Western-centric construct of SBCD was recontextualized in various Hong Kong school contexts. Findings revealed teachers’ struggles with hegemonic discourses that constrained their autonomy in SBCD projects to benefit diverse learners, such as the accountability mechanism, linguistic imperialism, Western-centrism, and top-down curriculum decision-making. Situated in the local realities …

Encouraging Practitioner Research Engagement: Overcoming Barriers, Annie M. Cole

Journal of Practitioner Research

Despite a body of evidence showing the vast benefits of practitioner engagement in higher education research, the literature suggests that many practitioners do not regularly engage in research activities due to three main barriers: the busyness of daily practice, perceived irrelevance of research to practice, and inadequate training to engage in research. This article reviews the literature on each of these three barriers, providing practitioners in higher education insight into how to overcome these barriers to successfully engage in regular research. Through an analysis of current literature, this article furthers the understanding of practitioner research engagement despite common barriers.

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.
