Working Toward Linguistically And Culturally Responsive Math Teaching Through A Year-Long Urban Teacher Training Program For English Learners, Kim Song, Sarah A. Coppersmith

Educator Preparation & Leadership Faculty Works

This qualitative study examined how participating in-service teachers demonstrated linguistically and culturally responsive mathematical teaching (LCRMT) competences after they completed a year-long National Professional Development Program grant-funded project. A two-dimensional LCRMT framework was developed to measure participating teachers’ mathematical and mathematics-related competences. The qualitative data source was from three in-service teachers’ observations and interviews. The interview and observation data were analyzed using open and axial coding and activity systems. Three themes emerged: 1) mathematics-related content teaching practices, 2) tools to support mathematics learning, and 3) teachers’ mindsets and attitudes towards English Learner (EL) teaching.

A Reflection Of Real Time Educational, Within-Subjects Data In Diverse Classrooms: One-Way Anova As A Solution To Data With Nonignorable Missingness And Skew, Amilynn N. Campa

Honors Program Theses and Research Projects

Schools across the United States and throughout the world administer tests to students to evaluate their academic performance. In many instances, however, especially in classrooms with higher populations of racial/ethnic minorities and low SES students, there are often missing scores, attributed to higher rates of absenteeism among these demographics (Callahan, 2019; Friedman-Krauss & Raver, 2015; Evans, 2004). When evaluating within subjects, longitudinal data, many will utilize a pre, post significance test such as a paired samples T test or a Repeated Measures ANOVA, however, due to the assumptions of these tests, missing data has posed a problem and requires data …

The Transition From Stochastic To Deterministic Bacterial Community Assembly During Permafrost Thaw Succession, Stacey J. Doherty, Robyn A. Barbato, A. Stuart Grandy, W. Kelley Thomas, Sylvain Monteux, Ellen Dorrepaal, Margareta Johansson, Jessica G. Ernakovich

Faculty Publications

The Northern high latitudes are warming twice as fast as the global average, and permafrost has become vulnerable to thaw. Changes to the environment during thaw leads to shifts in microbial communities and their associated functions, such as greenhouse gas emissions. Understanding the ecological processes that structure the identity and abundance (i.e., assembly) of pre- and post-thaw communities may improve predictions of the functional outcomes of permafrost thaw. We characterized microbial community assembly during permafrost thaw using in situ observations and a laboratory incubation of soils from the Storflaket Mire in Abisko, Sweden, where permafrost thaw has occurred over the …

Ethoxylation And Polymerization Of Cardanol Derived Bifunctional Monomers, James Mgaya

Journal of Humanities and Social Sciences

Cardanol and its derivative; 3-(non-8-enyl)phenol (obtained by ethenolysis reaction of cardanol) were ethoxylated via one-pot reaction with urea and ethylene glycol using Na2CO3/ZnO as co-catalysts. The ethoxylates were later methoxycarbonylated using a 1,2-bis(ditertbutylphosphinomethyl)benzene (DTBPMB) modified palladium catalyst to produce ethoxylated bifunctional monomers. Polymerization of these monomers by heating in the presence of a standard polymerization catalyst, Ti(OBu)4, formed oligomers that were plastic-like. Analysis of these oligomers by MALDI-TOF MS indicated the condensation of up to nine monomer units.

New Metal Based Saturable Absorber For Ultrashort Pulse Generation, Muhammad Taufiq Ahmad

Student Works (2020-2029)

Cost-efficient, robust and flexible laser systems are vital for a wide-range of applications ranging from high-precision material processing to biomedicine. This thesis aims to explore pure silver and gold based saturable absorbers (SAs) as Q-switcher and mode-locker in various fibre laser cavities. The generations of Q-switched pulses in 1-,1.55-, and 2-micron regions have been successfully demonstrated using a pure gold, which was deposited using electron beam deposition onto a PVA thin-film as SA. For instance, a stable Q-switched thulium-doped fibre laser (TDFL) operating at 1949 nm was successfully demonstrated with the gold SA. The proposed laser generates Q switched pulses …

Identification Of Ecg Anomalies Through Deep Deterministic Learning, Uzair Iqbal

Student Works (2020-2029)

Electrocardiography (ECG) is a primary diagnostic tool for measuring the malfunctioning of the heart muscles in the context of morbidity of different cardiac diseases and arrhythmia. Different existing techniques and methods delivered accurate cardiac diseases myocardial infarction (heart stroke) and atrial fibrillation recognition. However, there are still some flaws in existing methods like recognition of special myocardial infarction situation flattened T wave in “Non-Specific ST-T Changes (nsst-t)” and reduction of computational cost in cardiac diseases recognition. Accurate recognition of cardiac diseases along with least computational complexity and feature analysis of flattened T wave in myocardial infarction remains an open job. …

Furthermore, it is now very convenient to communicate with each other through email and text messages. However, widespread networks also provide more attack surfaces for attackers. There are a variety of network attacks aimed at information theft. To better defend against those network attacks, one needs to have a broad knowledge of existing attacks. In this …

A Posteriori Error Estimates For Elliptic Eigenvalue Problems Using Auxiliary Subspace Techniques, Stefano Giani, Luka Grubišić, Harri Hakula, Jeffrey S. Ovall

Mathematics and Statistics Faculty Publications and Presentations

We propose an a posteriori error estimator for high-order p- or hp-finite element discretizations of selfadjoint linear elliptic eigenvalue problems that is appropriate for estimating the error in the approximation of an eigenvalue cluster and the corresponding invariant subspace. The estimator is based on the computation of approximate error functions in a space that complements the one in which the approximate eigenvectors were computed. These error functions are used to construct estimates of collective measures of error, such as the Hausdorff distance between the true and approximate clusters of eigenvalues, and the subspace gap between the corresponding true and approximate …

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 …

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 …

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 research literature suggests Small Island Developing States (SIDS) are vulnerable to climate change. Tourism in SIDS is sensitive to climate variations and dependence of the sector on natural resources (beaches, coral reefs) adds to their vulnerability. The purpose of this study is to assess climate impacts and adaptation within the tourism sector of a SIDS – The Bahamas that relies on tourism and faces climate vulnerabilities, as do other SIDS. Given the importance of tourism to their sustainable development by supporting economic growth and employment, this study identifies timely risks and adaptation planning for a tourism-based SIDS economy in …

Plio-Pleistocene Antarctic Ice-Ocean Interactions In The Ross Sea, Catherine Prunella

USF Tampa Graduate Theses and Dissertations

Warm, intermediate-depth Southern Ocean waters are implicated in recent Antarctic ice mass loss. Direct observations of Antarctic Ice Sheet (AIS) retreat are temporally limited, necessitating paleoceanographic records of ocean-ice interactions during past warm climate intervals. Deepsea and ice-proximal sediments record orbitally-paced glacial-interglacial fluctuations in AIS volume during the Plio-Pleistocene (last 5 million years; Ma), but the total contribution of the AIS and the role of ocean heat in these fluctuations remain unresolved. To address the response of Antarctica’s ice sheets to changing ocean temperatures during the Plio-Pleistocene, International Ocean Discovery Program (IODP) Expedition 374 recovered sediments from the Ross Sea …

Modeling Early Life: Ontogenetic Growth And Behavior Affect Population Connectivity In Gulf Of Mexico Marine Fish, Kelly Vasbinder

USF Tampa Graduate Theses and Dissertations

This dissertation is an examination of growth, behavior, and dispersal during the early life stages of marine fishes in the Gulf of Mexico. Understanding movements of early life stages is a key part of managing exploited fish populations. Position in the water column can impact larval dispersal, since it determines those currents to which larvae are exposed. First, I investigated the relationship between length and age in early life stages of marine fishes. I found that demersal fish taxa tend to be represented by exponential models, while pelagic fish tend to be represented by linear models. I suggest this may …

Proximity-Induced Magnetization In Graphene: Towards Efficient Spin Gating, Mihovil Bosnar, Ivor Lončarić, P. Lazić, Kirill Belashchenko, Igor Žutić

Kirill Belashchenko Publications

Gate-tunable spin-dependent properties could be induced in graphene at room temperature through the magnetic proximity effect by placing it in contact with a metallic ferromagnet. Because strong chemical bonding with the metallic substrate makes gating ineffective, an intervening passivation layer is needed. Previously considered passivation layers result in a large shift of the Dirac point away from the Fermi level, so that unrealistically large gate fields are required to tune the spin polarization in graphene (Gr). We show that a monolayer of Au or Pt used as the passivation layer between Co and graphene brings the Dirac point closer to …
