Tools, Differentiation, And Professional Growth: What Preservice Teachers Gain From Attending A Mathematics Teaching Conference, Heidi Eisenreich, India Fleming

Proceedings of the Annual Meeting of the Georgia Association of Mathematics Teacher Educators

This study explores how Preservice Teachers’ (PSTs’) attendance at a professional mathematics teaching conference influences their development as future teachers. Fourteen University PSTs attended the Georgia Mathematics Conference (GMC), a two-and-a-half-day teaching conference for K–16 mathematics teachers and administrators. Using constant comparative analysis to code qualitative data, we analyzed responses from one question on tool usage in pre- and post- conference surveys. Initial findings indicate that conference attendance increased PSTs' commitment to ongoing professional development, while simultaneously helping them develop more nuanced understandings of the complexity of teaching.

Harnessing Se Community Knowledge For Developer-Centric Code Intelligence, Chengran Yang

Dissertations and Theses Collection (Open Access)

The integration of Large Language Models (LLMs), particularly those tailored for programming tasks—referred to as code LLMs—has created novel opportunities to enhance developer productivity. These advanced models automate routine and repetitive coding tasks, such as code generation and debugging, and enable faster prototyping and more efficient problem-solving. Despite these remarkable advantages, the current generation of code LLMs exhibits notable limitations that impact their practical effectiveness in real-world software engineering scenarios. These models frequently produce code that is inefficient or suboptimal in runtime performance, demonstrate opaque reasoning processes, and struggle to adapt effectively to diverse developer contexts and specific requirements. Moreover, …

The Role Of Employee Engagement In Predicting Risk Management Outcome, Jenny Tan

Dissertations and Theses Collection (Open Access)

Risk performance is a key business performance indicator as it measures how well an organization manages its uncertainties. Well-balanced risk performance instills confidence in stakeholders (including investors) and improves organizational performance broadly speaking. This dissertation studies the relationship between Perceived Organizational Support, employee engagement and risk appetite and how that relates downstream to organisational risk performance. Using the lens of Social Exchange Theory (SET; Blau, 1964) I examine how perceived organizational support (POS) predicts employee engagement and how this then relates to risk appetite and subsequent levels of risk taking in an organization. I then make predictions about how exchange …

Corporate Governance And Tax Compliance Of Publicly Listed Companies In The Philippines, Hans Theo S. Ramirez, Jhulliane Kiss A. Mijares, Alyson Jane D. Constantino, Marwel B. Toledo, Jacob Marius L. Tolentino, Elma L. Mallorca

Journal Article

Corporate tax compliance is the key to the development of the economy. Annual effective tax rate is applied in this study to identify what corporate governance mechanisms—shareholders, management, and corporate social responsibility (CSR) strategy—are responsible for inducing tax compliance. A panel regression analysis of 20 listed companies in the Philippines from 2012-2023 has shown that the sole determinant of corporate tax compliance is CSR strategy. Effective CSR practices help firms to minimize tax avoidance by paying the appropriate corporation tax rate mandated by law. This is an example of how CSR can enhance ethical financial behavior. This study integrates stakeholder, …

Teacher Grit, Commitment, And Psychological Well-Being: A Structural Equation Modelling Analysis, Mary Ann A. Artizuela, Fraide A. Ganotica Jr.

Journal Article

Although teacher well-being has been widely examined, limited research has explored how grit and commitment jointly influence psychological well-being among Filipino educators within a robust theoretical framework. This study addresses this gap by investigating the role of grit and commitment in shaping teacher well-being at Palawan State University in Puerto Princesa City, Philippines. According to the Engine Model of Well-being, individual traits like grit serve as inputs that shape internal processes (e.g., teacher commitment), ultimately influencing well-being. Guided by this framework, grit was conceptualized as an input, teacher commitment as a mediating process, and psychological well-being as an outcome. Employing …

Chemistry Of Inclusions By Size In Three Primary Copper Anodes, Charles Campbell, Michael Moats

Materials Science and Engineering Faculty Research & Creative Works

Three copper anodes from different commercial electro refineries were characterized to measure inclusion chemistry, size (diameter), and morphology. An automated scanning electron microscope (SEM) paired with energy-dispersive X-ray spectroscopy (EDS) was used to examine hundreds of inclusions near the mold and set sides of each anode. The investigation revealed that in the two anodes with less impurities (99.65% Cu and 99.75% Cu), many of the inclusions were Cu2O with an average diameter of 2 microns. The greater impurity anode (99.05% Cu, 4076 ppm Pb, 1939 ppm As, 635 ppm Bi) contained significant numbers of complex oxide inclusions, averaging 4.6 microns …

The model is validated using experimental data from this study as well as literature on the DRI pellet–molten slag system. Results indicate that, despite the increased enthalpy demand associated …

Selective Nickel Leaching And Preparation Of Battery-Grade Nickel Carbonate From Copper-Rich Industrial Intermediate, Janaka Jayamini Wijenayake, Michael S. Moats, Lloyd Masuzyo Mseteka, Lana Alagha

Materials Science and Engineering Faculty Research & Creative Works

The rising demand for electric vehicles (EVs) has driven a significant increase in nickel consumption, a critical element in EV battery production. An industrially viable hydrometallurgical process was developed for the selective recovery of nickel from a copper-rich industrial intermediate, containing approximately 70 wt.% Cu and 6 wt.% Ni, predominantly as sulfides alongside minor impurities. Approximately 90% of nickel was selectively extracted via single-stage atmospheric pressure leaching using HCl and H2O2 at 95 °C for 12 h, with the majority of copper retained in the leach residue, which can be utilized as a valuable feedstock for copper smelters. The selectivity …

Competition Of Light-And Phonon-Dressing In Microwave-Dressed Bose Polarons, G. M. Koutentakis, S. I. Mistakidis, F. Grusdt, H. R. Sadeghpour, P. Schmelcher

Physics Faculty Research & Creative Works

We theoretically investigate the stationary properties of a spin-1/2 impurity immersed in a one-dimensional confined Bose gas. In particular, we consider coherently coupled spin states with an external field, where only one spin component interacts with the bath, enabling light dressing of the impurity and spin-dependent bath-impurity interactions. Through detailed comparisons with ab-initio many-body simulations, we demonstrate that the composite system is accurately described by a simplified effective Hamiltonian. The latter builds upon previously developed effective potential approaches in the absence of light dressing. It can be used to extract the impurity energy, residue, effective mass, and anharmonicity induced by …

Effective Two- And Three-Body Interactions Between Dressed Impurities In A Tilted Double-Well Potential, F. Theel, A. G. Volosniev, D. Diplaris, F. Brauneis, S. I. Mistakidis, P. Schmelcher

Physics Faculty Research & Creative Works

We explore the impact and scaling of effective interactions between two and three impurity atoms, induced by a bosonic medium, on their density distributions. To facilitate the detection of mediated interactions, we propose a setup where impurities are trapped in a tilted double-well potential, while the medium is confined to a ring. The tilt of the potential breaks the spatial inversion symmetry allowing us to exploit the population of the energetically elevated well as a probe of induced interactions. For two impurities, the interaction with the medium reduces the impurity population at the energetically elevated well, which we interpret as …

Bound Deuteron-Antideuteron System (Deuteronium): Leading Radiative And Internal-Structure Corrections To Bound-State Energies, Gregory S. Adkins, Ulrich D. Jentschura

Physics Faculty Research & Creative Works

We evaluate the energy levels of the deuteronium bound system, which consists of a deuteron and an antideuteron, with a special emphasis on states with nonvanishing orbital angular momenta. The excited atomic bound states of deuteronium constitute probes for the understanding of higher-order quantum electrodynamic corrections for spin-1 particles in a bound system where the typical field strength of the binding Coulomb field (at a distance of the generalized Bohr radius) exceeds Schwinger's critical field strength. For states with nonvanishing angular momenta, effects due to the internal structure of the deuteron and virtual annihilation contributions are highly suppressed. Relevant transitions …

We used light curves from the Transiting Exoplanet Survey Satellite (Tess), which observed BB Per in five sectors, to determine its photometric properties and a precise orbital ephemeris. The solution of the Tess light curve in Phoebe results in a detached configuration, where the temperature of the primary component was fixed to T 1 = 5 300 K according to Lamost, which gives us T 2 = 5 050 ± …

False Friends: The Pereiaslav Agreement Of 1654 And Competing Narratives In Russian And Ukrainian Historiographies, Jiansheng Zhang

Armstrong Undergraduate Journal of History

The Pereiaslav Agreement of 1654, concluded between the Cossack Hetmanate and the Grand Duchy of Muscovy at the Pereiaslav Rada, marked the beginning of modern Cossack-Muscovite (in perspective, Ukrainian-Russian) relations. Owing to its central role in shaping both Russian and Ukrainian national narratives, the agreement remains a highly contentious event in Eastern European history. Historians from the Russian and Ukrainian historiographical traditions offer divergent interpretations of how the agreement was conceived and received by the Cossacks and Muscovites. Drawing on a wide range of primary and secondary sources, this essay critically examines these competing narratives and concludes that Ukrainian historiography—emphasizing …

Improving Patient Portal Messaging Workflow, Tanya M. Fitzpatrick

All Doctor of Nursing Practice (DNP) Scholarly Projects

Problem: Inefficiencies in patient portal secure messaging between providers and patients in a large primary care practice led to delayed resolution times, averaging 5.6 days per message. Most messages were closed by physicians or advanced practice providers, resulting in imbalanced workload distribution, increased provider burden, and reduced communication efficiency. The lack of standardized guidelines for message use, character limits, or triage processes contributed to workflow disruptions, a diminished patient experience, and unreimbursed provider time.

Aim of the Project: The aim of the project was to reduce average portal message closure times by at least 38% through the implementation of standardized …
