Neuropsychological Profiles To Aid In Determining The Necessity For Neuroimaging Reviews: Providing Evidence For A Screener For Cerebrovascular Abnormalities, Kayla Blaire Miller

Theses and Dissertations

This study aimed to provide evidence for a white matter abnormality (WMA) screener by investigating whether commonly used neuropsychological measures of executive functioning and processing speed have predictive power for identifying high WMA burden.

Participants were administered a brief neuropsychological evaluation by a doctoral student under the direct supervision of a board-certified clinical neuropsychologist and underwent an MRI scan. A neurologist rated each participant’s MRI results using the Fazekas scale. A total of 178 participants were included, divided into two groups based on their Fazekas rating: low WMA burden (46%) and high WMA burden (54%).

A confirmatory factor analysis indicated …

The Effect Of Resilience: Exploring The Link Between Depression And Cognitive Performance In A Memory Disorder Clinic Population, Amanda Capriglione

Theses and Dissertations

Introduction: Research has consistently shown that depressive symptoms are associated with cognitive impairments, namely in memory, attention, and executive functioning (for a review, see Rock et al., 2014), particularly in individuals with mild cognitive impairment (MCI). As MCI is often a precursor to dementia, understanding and addressing modifiable factors that influence this trajectory is essential for prevention and intervention efforts. Resilience, defined as the capacity to adapt positively to adversity, has been identified as a potential protective factor against age-related cognitive decline. Prior studies (e.g., Laird et al., 2019b; Miller et al., 2023) suggest that resilience buffers against the cognitive …

Digital Maturity In The Administrative Prosecution In Egypt, Asmaa A. Hassan

Theses and Dissertations

The growing deployment of information and communication technologies in public service delivery, in general, and in the judiciary in particular, underscores the need for an assessment tool to evaluate digital maturity. Understanding digital maturity, a state in which an organization has completed digital development, helps diagnose the status quo, identify enablers, and address challenges, and consequently provide a roadmap for efficient improvements. This study aims to examine key factors affecting digital maturity within the Administrative Prosecution (AP) in Egypt, a pillar of the judicial authority and mandated to investigate financial and administrative violations committed by public servants. A mixed-methods approach …

From Planned To Lived: Street-Level Transformation And The Production Of Urban Space In New Cairo, Seba Abouyoussef

Theses and Dissertations

Egypt's new cities program has produced four generations of satellite developments, yet none have been systematically evaluated for how they perform once inhabited. Each is planned as a prototype — functionally zoned, automobile-oriented, image-driven — with little regard for the social, cultural, and behavioral dynamics that will shape it. This thesis examines the gap between the planned city and the lived city by tracing how three streets in New Cairo transformed over a fifteen-year period (2010–2025) through everyday use, stakeholder interaction, and pivotal trigger events.

The research follows a qualitative, multi-phase methodology — combining historical and physical mapping, behavioral observation, …

The research is structured within an Asset-Design-Evaluate (ADE) framework and grounded in Radical Constructivism, Situated Learning theory, and the Design-Dynamics-Experience (DDE) framework, positioning the physical architecture of the site as the primary source of visitor knowledge through observation-based interaction tasks.

The application, titled "Qalawun's Treasure," comprises eight spatially anchored hotspots across the mausoleum, madrasa, and bimaristan of …

Technology, Power, And Colonial Modernity: The Making Of The Egyptian Railways, Ahmed Mohamed Rahmy

Theses and Dissertations

This thesis examines Egyptian railways as a technology of power through which modern temporal order was gradually formed, reorganized, and contested. Focusing on the period from 1850 to 1920, it argues that railway infrastructure did more than facilitate mobility, economic exchange, and imperial administration: it reorganized the temporal relations through which social life was governed and experienced. Timetables, standardized schedules, fares, penalties, stations, and administrative procedures made punctuality, regularity, and measurable time appear as neutral requirements of life, while positioning existing ecological, agricultural, religious, and communal rhythms as signs of backwardness.

The thesis draws on British official correspondence, parliamentary debates, …

Between The Lens And The Gaze: Reflections Of Femininity In Film, Noureen Sakr

Theses and Dissertations

This thesis explores the male gaze’s construction of femininity through the use of glass and reflective surfaces, particularly mirrors, windows, glasses, and cameras in film. Reflections and depictions of women are recurring motifs in cinema, often symbolizing dynamics of perception and power. This thesis mobilizes related psychoanalytic and feminist conceptions to examine and compare the recurring visual motifs in the following films: Alfred Hitchcock’s Strangers on a Train (1951) and Rear Window (1954), Paul Verhoeven’s Basic Instinct (1992), & Darren Aronofsky’s Black Swan (2010). This thesis employs a qualitative, interdisciplinary methodology that integrates psychoanalytic theory, feminist film theory, literary criticism …

Hell Reimagined: Dante’S Inferno And The Secular Afterlives Of Divine Punishment, Yara Mohamed El Hashimi

Theses and Dissertations

This thesis examines contrapasso and how it changes across different media and different sources of moral authority. In Chapter One, I examine four different cantos of Dante’s Inferno and rely on Teodolinda Barolini’s work to examine textual contrapasso. Chapter One also discusses how Dante’s work shows the sinner’s moral condition and makes it visible through the punishment inflicted. Additionally, Dante’s Inferno presents punishment as part of a divinely authorized moral order, which becomes important in Chapter Two when I examine how William Blake visually interprets and questions that system. In Chapter Two, I examine the works of Blake that correspond …

Policy Coherence And Private Sector Development In Egypt: Aligning Governance Reforms With Development Finance, Shereef El Tanahi

Theses and Dissertations

Despite record volumes of development finance flowing into Egypt, the private sector, particularly its micro, small, and medium enterprises, has yet to experience the broad-based growth these investments were designed to catalyze. Between 2020 and 2025, international development partners committed more than 15.6 billion dollars to Egypt's private sector, yet private investment remains a modest share of the national economy, and most domestic firms continue to face severe barriers to credit.

This thesis argues that the answer lies not in the volume of capital mobilized, but in the coherence of the policies that govern how that capital reaches firms. The …

Simulation-Based Assessment Of Operational And Retrofit Solutions For Effluent Compliance Of A Capacity-Limited Oxidation Ditch Wwtp, Ahmed Sameh Harash

Theses and Dissertations

Oxidation-ditch wastewater treatment plants (WWTPs) across Egypt's Nile Delta are increasingly carrying hydraulic and organic loads beyond what they were designed for. This work can be considered pioneering as this work compared operational and structural retrofit alternatives for such a plant within a single verified simulation framework. The present study fills that gap by building a digital twin of the Qaha WWTP, a dual-train Carrousel oxidation ditch in Qalyubia Governorate, calibrated to a baseline flow of 7,420 m³/day in the SUMO24 platform (a third-generation, open-source wastewater treatment process simulation software) using the SUMO2c biokinetic model (a simplified variant of Activated …

“The Light Of Certain Belief” – Orthodoxy Versus Innovation According To Abū Ḥāmid Al-Ghazālī’S Al-Risāla Al-Qudsiyyah, Thomas Robinson

Theses and Dissertations

This thesis examines the question of Islamic orthodoxy in the thought of Abū Ḥāmid al-Ghazālī, with particular attention to his Risāla al-Qudsiyya and its place within his wider intellectual and reformative project. It begins by exploring concepts of orthodoxy and heterodoxy across the Christian and Islamic traditions, arguing that orthodoxy emerges through processes of interpretation, doctrinal conflict, boundary formation, and communal consensus. Islamic orthodoxy is understood as the historically consolidated mainstream of belief rooted in the Qurʾān, the Sunnah, the authority of the early community, and the scholarly tradition.

The central argument of the thesis is that al-Ghazālī conceives of …

Here Comes The Sun: A Diachronic Study Of The Role Of Music In The Amarna Period, Waleed Hawatky

Theses and Dissertations

Music has and continues to play a prominent role in the lives of individuals and in society, hardwired into the human experience and integral to our understanding of the world in both its tangible and intangible manifestations. This was no different in dynastic Egypt, where abundant iconographic and physical evidence from the Old Kingdom onward shows music performed in many diverse contexts at every social level.

Music appears not only to gain prominence during the reign of Amenhotep IV/Akhenaten (c. 1353–1335), also known as the Amarna Period, but also to develop innovations, including new kinds of instruments and musical ensembles, …

Dynamic Baseline Schedule Updates Using Digital Twinning: A Case Study On Aluminum Formwork Construction, Ahmed Hamdi Sweilam

Theses and Dissertations

Repetitive high-rise construction using aluminum formwork couples consecutive floor cycles through a reused panel set and a floor-level inspection and pour barrier, so productivity loss compounds upward rather than being absorbed locally. The baseline schedule is nevertheless fixed before execution and is not revised as evidence of realized productivity accumulates. This thesis develops a simulation-based digital twin that updates the baseline from observed as-built durations and acts on its own forecast. A discrete-event simulation of a ten-story residential tower is built in AnyLogic® and verified analytically at 180.00 hours per floor. After each completed floor the twin infers activity productivity …

A Maximum Energy Release Rate Computational Framework For Fatigue Crack Trajectory And Life Prediction Under Mixed-Mode Proportional And Nonproportional Loading, Nahla Helmy Matar

Theses and Dissertations

The problem of mixed-mode fatigue crack growth has been a persistent research challenge. The determination of fatigue crack propagation direction directly impacts the safety and integrity of components and structures, making it crucial in various industrial applications, including welded drilling pipes, aerospace, and automotive engineering. Unlike uniaxial loading, mixed-mode cracks tend to change direction frequently (kinking), and nonproportional loading adds to the complexity of the problem. This research aims to estimate the crack propagation direction and fatigue crack life in linear elastic materials subjected to mixed-mode (I+II) loading conditions under proportional or non-proportional cyclic loading. Numerical software was developed based …

A Policy Analysis Of Accountability And Governance In Journalism By Artificial Intelligence (Ai) In Egypt, Amira Ahmed Salama

Theses and Dissertations

The growing use of Generative Artificial Intelligence (GenAI) and AI-assisted tools in journalism raises governance questions concerning accountability, human oversight, transparency, verification, editorial responsibility, and implementation. In Egypt, these issues arise within an emerging but fragmented governance environment that includes national AI guidance, media regulation, professional self-regulation, and developing newsroom practices. This study examines how these arrangements can be integrated into a coherent national sector-specific policy framework for GenAI and AI-assisted journalism.

The study adopts a qualitative methodology combining a descriptive qualitative document analysis with stakeholder semi-structured interviews. Four governance instruments were analyzed: the Council of Europe’s Guidelines on the …

Knowledge, Attitudes, And Practices (Kap) Of Parents Regarding The Prevention And Control Of Childhood Iron Deficiency Anemia In Egypt: A Cross-Sectional Study, Omnia Soliman

Theses and Dissertations

Childhood Iron Deficiency Anemia (IDA) remains a major public health challenge in Egypt, where its persistently high and rising prevalence carries substantial consequences for child growth, cognitive development, immunity, and long-term health outcomes. Globally, approximately 40% of children aged 6–59 months are affected by anemia (World Health Organization, 2025), and Egypt mirrors this burden, with national data showing a worsening trend in recent years. In Egypt, national strategies have traditionally focused on biomedical interventions such as iron supplementation and food fortification, while less attention has been directed toward behavioral and household-level determinants, particularly parental knowledge, attitudes, and practices (KAP) related …

Extending Geometric Acoustic Ray Tracing To Multi-Room Environments: A Case Study On Gunshot Sound Transmission Between Adjacent Rooms, Tyler Ton

Theses and Dissertations

Accurate localization of gunshots in multi-room building environments remains a challenging problem in acoustic forensics and public safety applications. Existing approaches model sound propagation within a single room, neglecting the transmission of acoustic energy through walls and other building materials. This thesis presents a study on modeling multi-room gunshot acoustic transmission, combining geometric ray tracing with structural acoustic transmission-loss modeling to generate impulse responses for two horizontally adjacent rooms separated by a shared wall, providing a foundation for future inter-room gunshot localization work. The proposed system uses GSound-SIR, a geometric acoustics engine, to simulate sound propagation in both of the …

A Data-Driven Koopman Framework For Station-Keeping On Near Rectilinear Halo Orbit, Anusha Sharma Malladi

Theses and Dissertations

Cislunar missions have gained significant attention in recent decades, motivating the need for efficient modeling and reliable control. In this work a Koopman operator based framework is developed for approximating the error dynamics around a reference Near Rectilinear Halo Orbit (NRHO) in the Earth-Moon Circular Restricted Three-Body Problem (CR3BP). A decoder free neural network is used to learn a lifted linear representation of the nonlinear CR3BP dynamics and a residual based approach is used to identify the corresponding control input matrix. The model is then implemented in a receding-horizon target point controller and compared with uncontrolled propagation and a State …

Developing Imitation Learning Policies By Exploring Diffusion Framework For Quadcopters, Likith Swamireddy

Theses and Dissertations

Imitation learning offers a promising approach in developing near-optimal onboard policies for nonlinear systems, by learning from computationally expensive trajectory planners during offline training. Existing State-of-the-art methods commonly learn deterministic mappings from observations to actions by training fast neural networks to mimic the expert demonstrations, which can limit their ability to capture the action distribution, when the policy is trained on multiple possible expert commands to reach the same target, and this may lead to unsafe scenarios in the obstacle environments. To address these challenges, this study explores Diffusion Models (DMs) as a feedback controller for quadcopters that learns the …

A Hybrid Rule-Based And Large Language Model Framework For Extracting Acronym–Definition Pairs From Scientific Literature, Petro Skrypnyk

Theses and Dissertations

Authors of scientific papers rely heavily on acronyms and often use them without defining them, making the literature harder to read and index. This thesis develops and evaluates a hybrid rule-based and large language model (LLM) framework that extracts acronym–definition pairs from scientific PDF documents. It extends an earlier Rowan University system that combined a regular-expression parser with a single LLM on 200 papers. That system showed that neither the parser nor the LLM alone is sufficient for accurate extraction of the pairs. The framework is a fully automated pipeline from PDF input to scored results. It compares four LLM …

Effects Of Social Comparison Instructions On Affect, Motivation For Healthy Behavior, And Health Behavior Selections: Guidance To Identify Or Contrast, Raj Harsora

Theses and Dissertations

Engaging in healthy behaviors early in life is crucial for preventing noncommunicable diseases such as type 2 diabetes, cancer, and heart disease. College is an optimal period to establish these habits, yet students often engage in poor dietary and physical activity practices; thus, identifying effective health behavior change techniques for this population is essential. Social comparisons are known to influence health behaviors, yet no research has tested comparison instructions as a behavior change technique, particularly identification versus contrast with upward and downward targets. Using a preregistered protocol (https://osf.io/z29en), we tested whether guiding college students (N=664) to identify with or contrast …

Polymer Nanocomposite Dielectrics For High-Temperature Superconducting Cables: Cryogenic Characterization And Testing Environment Development, Jared R. Ericksen

Theses and Dissertations

High-temperature superconducting (HTS) cables require dielectric insulation materials that can withstand cryogenic operating environments while maintaining electrical reliability, mechanical stability, and manufacturing compatibility. This thesis investigates polyamide-based polymer nanocomposites as candidate HTS cable insulation materials and develops cryogenic testing platforms for evaluating thin-film dielectrics at reduced temperatures. Two silicon-based filler systems are studied: sol-gel-derived silicon dioxide (SiO 2 ) nanoparticles and polyhedral oligomeric silsesquioxane (POSS). Dielectric breakdown behavior is evaluated under DC and AC high-potential testing, while mechanical behavior is assessed through tensile testing. The results show that PA/SiO 2 nanocomposites provide the strongest overall balance of mechanical reinforcement and …

The Impact Of Stigma On The Mmpi-3 Scores Of An Indo-Caribbean Community Sample, Julia Persaud-Naipaul

Theses and Dissertations

Evaluation of personality and psychological disorders is accomplished through the use of psychometric measures. However, tests require interpretation of test responses using a normative criterion based on a particular population that may not fully consider the effect of cultural influences on an individual’s level of willingness to report psychological difficulties. For example, individuals in collectivistic cultures may not be as willing to self-report problems because mental illness is often perceived as a source of embarrassment and shame. One culturally unique population that has been overlooked in psychological assessment is the Indo-Caribbean population. Their specific cultural values, beliefs, attitudes, and practices …

Workers Authoring Assessment: Play And Power In Early Childhood Education, Phoebe M. Gilpin

Theses and Dissertations

Researchers assert that play-based pedagogy is an effective approach to teaching young children, but there is less consensus on the specific methods of play-based teaching. This mixed-methodology exploratory case study investigated early childhood (EC) educators’ conceptualizations of play-based pedagogy in three phases: Phase 1’s quantitative measure testing found a mismatch between researchers’ conceptualization of play-based pedagogy and EC educators’ (n=183) understandings. In Phase 2, EC educators (n=3) articulated their perspectives about teaching through play and co-authored a new tool, the Teacher-Authored Play and Teaching Scale (TAPTS). Within Phase 3, EC educators (n=60) completed the TAPTS, which I interpreted through a …

Developing An Object Level Understanding Of Sine And Cosine As Ratios And A Coherent Trigonometry, Jeffrey Peter Nair

Theses and Dissertations

Solving right-triangle problems as well as integrating right-triangle and circular trigonometry into a coherent understanding are documented challenges for students. Prior research has deeply investigated students constructing ratio meanings for sine and cosine using a circle-first approach, which then can be extended to right triangles. Also, past work has separately documented distinct meanings that are useful for sine and cosine, in addition to the ratio meaning, including as lengths in a unit circle and coordinate points. This study took these existing ideas and put them together into one possible developmental progression, based on APOS theory, where students can learn length, …

Actionable Hydrologic Data To Information With National Water Model-Based Derived Dataset, Cutting-Edge Data Services, And Agentic Ai System, Sujan Chandra Mondol

Theses and Dissertations

Hydrologic data are the cornerstone of many complex hydrologic research and operational workflows that produce useful hydrologic information for water resources decision-making, flood risk communication, and water availability implications. The National Water Model (NWM) is a valuable source of hydrologic data, particularly for its extended coverage of unmonitored streams and the large-scale continuity of hydrologic processes. Precomputed secondary datasets derived from this simulated data, such as streamflow indices, can improve operational efficiency through thresholding. Disseminating the data through modern technologies, such as application programming interfaces, is required for ready integration into applications. However, if extraction requires an intermediate service, there …

"Tithing Is An Insurance Premium": A Framing Analysis Of Speaker Innovation And Diachronic Trends In Latter-Day Saint Religious Discourse, Reid Empey

Theses and Dissertations

Religious language relies on shared metaphor and frames that contextualize religious experience and practice. Current approaches to frame semantics (Fillmore 1982) and cognitive metaphor (Lakoff & Johnson 1980) lend important insight into religious language, particularly in describing the role that figurative language serves in a religious speech community. However, a vital component of many religious speech communities is the presence of and engagement with a scriptural canon, which often contains metaphorical and framing language that religious speakers can directly reference. Yet, past conceptualizations of speech communities have not accounted for this engagement with a shared canon. To illustrate the role …

Multi-Band Extinction Modeling In Early-Type Galaxies With Circumnuclear Disks, Nonnie Bash

Theses and Dissertations

In this thesis, we present a spatially resolved, multi-band dust-attenuation method for correcting the stellar luminosity models used in dynamical supermassive black hole (BH) mass measurements. If uncorrected, dust extinction effects may dominate over other systematic uncertainties when determining the BH mass ($M_\mathrm{BH}$). We expand on a simple dust-attenuation method that treats the circumnuclear disk as a thin dust layer embedded in the galaxy midplane. Using a Multi-Gaussian Expansion, we create a three-dimensional stellar luminosity model to calculate the fractions of stellar light originating in front of and behind the disk along each line of sight. We infer the pixel-by-pixel …
