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 …

Traumatic Brain Injury In Childhood And Adolescence: Relationship To Impulsivity, Behavioral Disorders, And Adverse Outcomes For An Incarcerated Male Adult Sample, Alexis Tillman

Theses and Dissertations

Traumatic brain injury (TBI) sustained during critical periods of early development has wide-ranging effects on cognitive, emotional, and behavioral adjustment that may persist into adulthood. Within the forensic population, there is a clear overrepresentation of head trauma. Although research publications have examined the impacts of TBI on psychological challenges within the general population, limited research has explored its relationship with impulsivity, behavioral disorders, and adverse outcomes in an adult incarcerated population. The purpose of this study was to examine the associations between age of first TBI, severity of TBI, and frequency of TBIs in childhood and adolescence and indices of …

How Does Foreign Direct Investment (Fdi) Impacts Egypt Economic Stability From The Specific Focus Of Exchange Rate And Economic Growth, Mohamed Medhat Merdan

Theses and Dissertations

This thesis examines the relationship between foreign direct investment (FDI) and economic dependency in Egypt, focusing on two channels through which such dependency may manifest: exchange rate volatility and economic growth. FDI has historically financed a disproportionately large share of Egypt's gross fixed capital formation relative to comparable regions, yet rigorous empirical research on its macroeconomic consequences within the Egyptian economy remains limited. Drawing on Dunning's eclectic (OLI) paradigm and Porter's diamond model, this study develops three hypotheses and tests them using an ARDL bounds testing approach applied to fifty-five years of annual data spanning 1970 to 2025.

The empirical …

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 …

Eritrean Refugees Between Securitization And Survival Along The Sahara Route To Egypt, Zeina Shoukry

Theses and Dissertations

Eritrea remains one of the largest refugee-producing countries in the world, with mandatory military conscription serving as a primary driver of displacement. This thesis examines the precarious journey of Eritrean refugees across the Sahara Desert en route to Egypt, situating this movement within the broader context of border securitization. It argues that the journey itself constitutes a critical and often overlooked phase of the migration process, as significant as both departure and destination.

Drawing on migration infrastructure theory and migrant network theory, this study foregrounds Eritrean refugees’ agency and resilience. It analyzes how refugees mobilize knowledge, digital technologies, social networks, …

Organizational Planning Practices Under Uncertainty: The Case Of Ngos In Hadhramaut, Yemen, Khulood Taleb Alamodi

Theses and Dissertations

This study examines how local non-governmental organizations (NGOs) in Hadhramaut, Yemen plan and operate under conditions of fragility and uncertainty. Although strategic planning is often presented as a formal and structured process, NGOs in fragile settings face ongoing disruption, unstable funding, and weak institutions. This study asks how planning takes place in practice under these conditions. The study uses qualitative data from 22 semi-structured interviews with NGO leaders, staff, and external actors. A conceptual framework combining contextual fragility, resource dependence, organizational capacity and resilience, and legitimacy and networks was used to examine how these factors shape organizational planning. The findings …

Palestinian Motherhood In Lebanon: An Analysis Of The Legal And Humanitarian Systems, Enje Matar

Theses and Dissertations

The lives of Palestinians in Lebanon are shaped by a diversity of factors that are exogenous and endogenous. The aim of this thesis is to analyze the impact of existing institutional, legal, and societal structures on Palestinian refugee mothers. It answers the following main question: how do the legal and humanitarian systems in Lebanon impact Palestinian mothers? It specifically scrutinizes 1) How do these systems shape family dynamics, maternal relations with children, and mothers’ daily lives? 2) How are these systems gendered in ways that represent broader questions of power and control? 3) How do mothers respond to these systems …

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, …

Beyond The Legal Black Hole: Hyper-Legality, Deferral, And Detention In Northeast Syria, Grace T. Harmon

Theses and Dissertations

This thesis examines the detention of suspected ISIS affiliates and their family members held in facilities administered by the Kurdish-led authorities in North-East Syria. Thousands of foreign nationals remain detained without trial, without repatriation, and in conditions widely criticized as inhumane. Existing scholarship and political discourse often describe these facilities as legal voids, limbo, or black holes where law has broken down or ceased to apply. This thesis challenges that characterization. Rather than existing outside the law, the facilities are governed through overlapping frameworks of international humanitarian law, international human rights law, counterterrorism security resolutions, and domestic laws. I argue …

Moreover, nano-indentation hardness measurements were conducted. Results showed that porosity significantly affected the integrity of …

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 …

This study develops and evaluates a web-based interactive application for the Qalawun Complex in Cairo, a fourteenth-century Mamluk monument of significant tangible and intangible cultural heritage value, with the aim of enhancing visitor engagement beyond the passive observation that characterizes most heritage visits. 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 …

The Smuggled Body: Embodied Experiences Of Sudanese Displacement Along The Sudan–Egypt Corridor, Marielys Padua Soto

Theses and Dissertations

The outbreak of conflict in Sudan in April 2023 triggered one of the world's largest displacement crises, forcing millions of Sudanese civilians to flee toward neighboring countries, particularly Egypt. As legal pathways became increasingly restricted following Egypt's tightening of visa policies, many asylum seekers relied on migrant smuggling networks to reach safety. This thesis examines how restrictive mobility regimes are materially experienced through the body by introducing the concept of the smuggled body, defined as the body through which the physical, emotional, and social consequences of border control, irregular mobility, and forced displacement are lived. Drawing on embodiment theory, border …

“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 …

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 …

Nanoscale Water Confinement And Coordination-Driven Ion Transport In Eutectogel Electrolytes For Electrochemical Energy Storage Applications, Abdallah Akar

Theses and Dissertations

The rapid expansion of renewable energy systems, portable electronics, electric vehicles, and smart grid technologies has intensified the demand for advanced electrochemical energy storage devices capable of delivering high power density, long cycling life, operational safety, and environmental sustainability. Among these technologies, supercapacitors have attracted considerable attention because of their rapid charge-discharge capability, excellent cycling stability, and high-power performance. However, their relatively low energy density remains a critical limitation that restricts their broader practical application. Since the energy density of supercapacitors scales with the square of the operating voltage, expanding the electrochemical stability window of the electrolyte represents one of …

Built By Hand, Run By Machine: Robots And The Uneven Displacement Of Native And Migrant Workers In Germany (2012-2024), Farida Mohamed Elkhosht

Theses and Dissertations

This study investigates whether industrial robot adoption generates differential employment effects for native and migrant workers across German local labor markets, using district-level data for 393 districts over 2012–2024. This question matters because Germany combines one of the world's highest concentrations of industrial robots with one of the largest migrant workforces in the OECD. Despite growing policy interest in the distributional effects of technological change, limited evidence exists on whether automation affects native and migrant employment differently within the same local labor markets. Using Bartik shift-share design to measure exogenous variation in robot exposure, the study finds that the effect …

Egypt’S Accession To Brics: Hedging And Strategic Positioning In A Multipolar Order, Daria Konstantinova

Theses and Dissertations

Amid Egypt’s longstanding, multifaceted cooperation with the U.S. and Western institutions, spanning political support, economic partnerships, and IMF/World Bank programs, 2024 BRICS expansion included Egypt as one of the new group’s members. This move might be explained by leadership strategic vision, domestic constraints, and geopolitical global and regional dynamics. This research explains the drivers behind Egypt’s accession to BRICS and the way this decision reflects Egypt’s strategic positioning in a changing global order, using agency-centered approach and the theoretical framework of strategic hedging.

While existing literature on BRICS expansion partially explains the reasons behind the new members’ accession and its …

The research investigated barriers and facilitators to employment for autistic youth and adults in Egypt, with a particular focus on technical and vocational education and training (TVET) as a potential pathway into work, and explored stakeholder perspectives on the potential, barriers, and conditions for adapting the Egyptian TVET system to improve their employability. Using the International Classification of Functioning, Disability, and Health (ICF) framework, this qualitative study relied on 20 semi-structured in-depth interviews with autistic youth and adults, parents …

Topographies Of Being: World-Making And Ontological Formation In Modern Saint Catherine, South Sinai, Ahmad Mahana

Theses and Dissertations

This thesis is an exploration of the ecological and sociological processes involved in the production of the socionatural space of the contemporary town and natural protectorate of Saint Catherine, South Sinai. Revered by all Abrahamic religions as the site of the Great Theophany, the town has perpetually been considered an area of immense spiritual and natural significance. In recent decades, however, the town has undergone a series of modernizing campaigns that have not only threatened the region’s natural environment and indigenous lifeways but have also jeopardized the plurality of its extant lifeworlds. By relying on a variety of ethnographic methods, …

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, …

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 …

Circulating Futures: Infrastructure, Value, And The Making Of Contemporary Egypt, Yasmine Abdeldayem

Theses and Dissertations

Since 2014, Egypt has undertaken an unprecedented expansion of its road network as part of a broader project of territorial development and national renewal. Roads are presented in this project as the connective infrastructure through which new cities, investment zones, and desert territories are brought into circulation. Yet their developmental effects are often difficult to discern: infrastructure is rapidly built but unevenly maintained, while projects justified in terms of mobility, growth, and public benefit can produce dispossession, exclusion, and new forms of risk. This thesis argues that roads cannot be understood solely through the developmental outcomes they are intended to …

Unearthing Potential: Impact Investors’ Perspectives On Egypt’S Social Enterprise Market, Yousef Hesham Shoukry

Theses and Dissertations

This thesis examines impact investing in Egypt from the vantage point of the impact investors, revealing that Egypt's constraint is not the availability of capital but its direction, as the absence of legal recognition, coordinated intermediaries, and a shared impact-measurement standard keeps capital out of a market otherwise rich in social enterprise potential. The study employed a constructivist grounded theory approach, drawing on eleven semi-structured interviews with impact fund managers, ecosystem enablers, and public-sector policy advisors operating in or considering Egypt's social enterprise market. Data revealed that practitioners converge on the founding principles of impact investment (combined financial and social …

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 …

The Functioning Of The Refugee Regime In The Global South, Rihem Sejil

Theses and Dissertations

Why do states continue to sign compacts and reaffirm responsibility-sharing, even as protection burdens fall increasingly on the Global South? This thesis argues that this concentration is a direct result of, rather than an exception to, international cooperation. It introduces the concept of "selective cooperation" to explain how states maintain formal commitments to protection while repurposing cooperation: shifting it from a remedial tool designed to assist burdened hosts to one focused on containment and preventing arrivals. Three mechanisms facilitate this shift: donor retrenchment, resettlement contraction, and externalization, with each mechanism closing gaps left by the others. Analyzing cases spanning resettlement, …

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 …

Undefined By Design: The Fragmented Public Understanding Of Diversity, Equity, And Inclusion (Dei) By Americans, Caroline Umphlet

Theses and Dissertations

Diversity, equity, and inclusion (DEI) policies have become a contentious issue in contemporary United States public discourse, yet a critical question remains as to whether the public shares a common foundational understanding of these terms. While DEI as a concept has developed and evolved significantly since the 1960s, public understanding remains ardently fragmented.

This thesis aims to answer the research questions: how does the 60+ age group in the US define and understand diversity, equity, and inclusion and DEI policies? The 60+ age group was specifically chosen because their definitions give insight into the publics’ understanding of policy topics when …

Sufism At The Service Of Ḥadīth Commentary: Re-Framing Al-Kalābādhī'S Baḥr Al-FawāʾId In Fourth-Tenth Century Transoxiana, Fadhil Yunus Alsagoff

Theses and Dissertations

This thesis examines Abū Bakr al-Kalābādhī’s (d. 380/990) understudied ḥadīth commentary, the Baḥr al-fawāʾid al-mashhūr bi-maʿānī al-akhbār. The first Anglophone study of the text as a whole, this thesis situates itself within the emergent literature on ḥadīth commentaries and challenges the prevailing scholarly tendency to reduce Sufi-authored commentarial texts to the ishārī method of interpretation and to treat them solely as repositories of Sufi themes. This thesis argues that, contrary to current perceptions of the text as primarily a work of Sufism, the Baḥr al-fawaʾid is first and foremost a work of ḥadīth commentary, its main intent being to …
