Educational Leadership, Leader-Member Exchange And Teacher Self-Efficacy, Gabriela Flores, Denver J. Fowler, Richard A. Posthuma

Journal of Global Education and Research

The purpose of this article is to examine social cognitive theory and social comparison theory, and how they are integrated to propose that self-efficacy mediates the relationship between leader-member exchange social comparison (LMXSC) and performance. Furthermore, the article supports the need for development and examination of the effects of educational leadership and teacher self-efficacy. That is, to determine if school leadership has an effect on teacher self-efficacy, and if teacher self-efficacy has an effect on student achievement. The preliminary conceptual model developed within the article includes insightful research questions to be considered for impending future studies. The authors hope this …

Course Design And Academic Outcomes In Quantitative Literacy After Eliminating Required Remediation, Jennifer E. Clinkenbeard

Numeracy

In Fall 2018, remedial mathematics courses were eliminated from the 23-campus California State University system under Executive Order 1110. Incoming first-year students were placed into college credit-bearing mathematics courses with options for corequisite support. This study examines the academic outcomes for students at California State University Monterey Bay in a college credit level quantitative literacy (QL) mathematics course with optional corequisite support during the 2018-2019 academic year. Taken together, the results of this study suggest that required remediation is not necessary for success in college-level QL. The corequisite support model also has potential to support more equitable outcomes for all …

Cognition In Health And Disease: Two Mouse Model Studies, Heather Lynn Mahoney

USF Tampa Graduate Theses and Dissertations

Cognitive and circadian dysfunction are common aspects of neuropsychiatric disease that are often overlooked in disease models and treatment strategies. In this work, we first evaluated the potential for cognitive enhancement in healthy adult mice by targeting a kinase involved in regulation of the molecular circadian clock. We then developed and characterized a model of neuropsychiatric disease that could present a target for rescuing circadian and cognitive deficits using this treatment.

Time-of-day effects have been noted in a wide variety of cognitive behavioral tests, and perturbation of circadian rhythms impairs hippocampus-dependent learning and memory. We first asked whether casein kinase …

Advancing Functional Scientific Literacy To Socioscientific Literacy As A Cross Disciplinary Educational Goal: A Philosophical Analysis, Kory Bennett

USF Tampa Graduate Theses and Dissertations

Educational experiences built upon the Socioscientific Issues (SSI) framework provide opportunities for teachers and students to reflectively and reflexively address ill-defined complex scientific issues that affect human beings around the planet. Through the practice of Socioscientific Reasoning (SSR), while grappling with SSI, students have the potential to develop a SSI functional perspective of scientific literacy (SL); functional scientific literacy (FSL). Due to the multidimensional complexity of many human issues in and out of the science classroom, students are required to develop various skills, dispositions, and problem-solving strategies that expand from and connect with a SSI functional perspective of SL.

Stygobitic Crustaceans In An Anchialine Cave With An Archeological Heritage At Vodeni Rat (Island Of Sveti Klement, Hvar, Croatia), Alessandro Montanari, Nicolas Cerveau, Barbara Fiasca, Jean-François Flot, Diana Galassi, Maurizio Mainiero, David Mcgee, Tadeusz Namiotko, Stefano Recanatini, Fabio Stoch

International Journal of Speleology

A group of four amphoras found in the anchialine cave of Vodeni Rat in the Croatian island of Sveti Klement, on a rocky ledge at 24 m water depth, indicates that a freshwater source was exploited at the bottom of this karstic pit by islanders and/or passing-by sailors from the late Roman Republican Period to the Early Medieval Period. In other words, prior to the 4^th–7^th century CE, Vodeni Rat was not an anchialine cave but a Pleistocene karstic pit with a freshwater pool at the bottom. Seawater started to infiltrate this cavity via newly opened fissures …

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 …

Quantifying The Impact Of Chronic Stress On Racial Disparities In Cardiovascular Disease, Nnadozie Emechebe

USF Tampa Graduate Theses and Dissertations

Background: Despite declining mortality in cardiovascular diseases (CVD), racial disparities between non-Hispanic Blacks (NHB) and to non-Hispanic Whites (NHW) persist. Although the prevalence of traditional risk factors of CVD such as hypertension, is higher in NHB compared to NHW, adjusting for this difference does not eliminate the disparity completely. This suggests other factors might explain the persisting disparities. Thus, the purpose of this dissertation is to quantify the impact of chronic stress in explaining the racial disparities in cardiovascular diseases (CVD). This dissertation contains three studies that addressed the following Specific Aims: Specific aims: 1) To create and assess the …

Cross-Host Correlations And Multivariate Effects Of Herbivore Specialization, Daniel J. Zydek

USF Tampa Graduate Theses and Dissertations

The distribution of insect herbivores among plant hosts is largely nonrandom: most herbivores have limited sets of hosts within one or a few plant families. This host use specialization is reinforced by traits that confer differential fitness across host plant species. Classic explanations for herbivore specialization predict that evolutionary trade-offs reinforce these relationships by imposing costs in the form of reduced potential fitness on alternative hosts, due to negative genetic correlations in fitness across hosts. This prediction that trade-offs constrain host use in herbivores can be tested with experimental evolution, by showing the direct evolutionary effects of host manipulation on …

Parent Coping And Sibling Relationship Quality In Pediatric Cancer: The Moderating Effects Of Parental Emotion Socialization Beliefs, Esther Davila

USF Tampa Graduate Theses and Dissertations

This study examined relations between parent coping and parent-, patient-, and sibling-reported perceptions of sibling relationship quality (SRQ), as well as potential moderating effects of parent emotion socialization (ES) beliefs in the context of pediatric oncology. Questionnaires were completed by 155 parents of pediatric oncology patients, 103 pediatric oncology patients, and 104 healthy siblings of pediatric oncology patients. Parent coping and ES beliefs predicted parent-perceived sibling warmth and dominance disparity. For parents low in emotion-dismissive ES beliefs, parent adaptive coping negatively predicted parent-perceived sibling dominance disparity. For parents low in emotion-coaching ES beliefs, parent adaptive coping positively predicted patient-perceived sibling …

Predictors Of Economic Outlook In Stability Operations, Juan Carlos Garcia

USF Tampa Graduate Theses and Dissertations

The participation of the United States military in stability efforts has increased dramatically since 2001. The core of current U. S. stabilization policies and measures derives from the US military's lessons in countering insurgencies since the late 20th century through the ongoing conflicts in Iraq, Afghanistan, and countries experiencing radical Islamic insurgencies. Counterinsurgency operations focus on gaining support from the relevant population through security, governance, and economic efforts. This research seeks to improve the understanding of the relationship between perceptions of security and governance on populations' economic outlook during stability operations.

I'M Going Digital: Potentials For Online Communities Through Internet Remix, Justin N. Nguyen

USF Tampa Graduate Theses and Dissertations

In the late 90s and early 2000s, computers and internet usage became more widespread. This widespread usage led to a proliferation of “digital objects” (digital versions of audio, video, image, text, etc.) dispersed through the internet. The instant and near-infinite reproducibility of digital objects combined with their ease of manipulation by computer users has led to their widespread recognition and use as tools of communication online. As a consequence, technology has allowed those traditionally thought of as consumers to become cultural producers by repurposing digital media objects. Because of this, internet remix of digital objects is one of the best …

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 …

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 …

Development Of Next-Generation, Fast, Accurate, Transferable, And Polarizable Force-Fields For Heterogenous Material Simulations, Adam E. Hogan

USF Tampa Graduate Theses and Dissertations

Theoretical modeling is extremely useful in guiding to experiment; however quantitatively accurate modeling of energy-relevant small molecule sorption at the heterogeneous interfaces present in metal-organic materials (MOMs) is currently challenging. MOMs are an emerging class of materials consisting of inorganic clusters and organic linkers that offer great potential in the areas of gas storage, gas separation, and catalysis due to the possibility of large surface areas, complex heterogeneous surfaces, and rational designability. Efficient chemical separations involving these materials could reduce the US’s total energy consumption by approximately 10 to 15%. In this dissertation, the parameterization of small molecules and metal …

System Support Of Concurrent Database Query Processing On A Gpu, Hao Li

USF Tampa Graduate Theses and Dissertations

The unrivaled computing capabilities of modern GPUs meet the demand of processing massive amounts of data seen in many application domains. While traditional HPC systems support applications as standalone entities that occupy the entire GPU, we propose a GPU-based DBMS (G-DBMS) that can run multiple tasks concurrently. To that end, system-level management mechanisms like resource allocation and buffer manager are needed to build such a concurrent database query processing system and fully unleash the GPUs’ computing power. However, CUDA does not provide enough OS-level functionalities to support it. Thus our research is focusing on implementing the optimization of resource allocation …
