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, …

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 …

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, …

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 …

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 …

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 …

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 …

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 …

“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 …

Enhancing User Engagement In Heritage Sites Through Interactive Digital Design: Development And Evaluation Of A Web-Based Application At The Qalawun Complex, Hend Bazeed

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 …

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 …

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, …

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 …

Adjudicating Technology Facilitated Violence Against Women In Egypt: Between The Text And The Application, Eman E. Zidan

Theses and Dissertations

Technology-facilitated violence against women (TFVAW) has surged on digital platforms, leading to a sharp rise in victimization rates among girls and women globally. Egypt’s pioneering cybercrime legislation, though comprehensive, remains gender-neutral and inadequate in judicial application. Community perceptions reveal systemic gaps that erode public trust and fuel demands for specialized protections. This study analyzes Egyptian judicial responses to TFVAW cases through comparative jurisprudence with jurisdictions that feature gender-specific norms. Findings demonstrate that textual provisions alone fail to arrest this escalating phenomenon, underscoring the need for integrated reforms: tailored legislation, heightened awareness campaigns, and collaborative education on rights, duties, and societal …

Mindfulness And Anxiety Symptoms: The Role Of Cognitive Reappraisal In Community Adults, Calla L. Pritulsky

College of Graduate Studies: Theses & Dissertations

Anxiety is the most common mental health condition worldwide and contributes to substantial societal costs, personal distress, and impairment (World Health Organization, 2023). Given its high prevalence, low treatment utilization, and modest response rates, identifying protective factors to inform prevention efforts is critical (Mamede et al., 2022; Mendelson & Eaton, 2018). Mindfulness, or the ability to nonjudgmentally pay attention to the present moment, comprises five key facets: observing, describing, acting with awareness, nonjudging, and nonreactivity (Baer et al., 2006b). Although mindfulness is inversely associated with anxiety, the mechanisms underlying this relationship remain unclear (Desrosiers et al., 2013). Cognitive reappraisal, defined …

Medical Distrust And Willingness To Engage In Mental Healthcare: The Moderating Roles Of Mental Health Literacy And Stigma Among Rural Populations, Alex Cudd

College of Graduate Studies: Theses & Dissertations

Healthcare and mental healthcare disparities among rural communities in the United States remain a persistent and growing public health concern, driven by both structural barriers and sociocultural factors that continue to compromise rural community members’ utilization of healthcare services. Though structural barriers to rural healthcare are well-documented, there are continued gaps in the literature related to the understanding of sociocultural mechanisms contributing to these disparities. The present study investigated the influence of medical distrust, mental health literacy, and perceived public stigma on attitudes toward seeking professional psychological help among rural adults living within the United States. A sample of 240 …

Turning To The Sacred: The Role Of Religious/Spiritual Coping In Psychological Outcomes Of Childhood Interpersonal Trauma, Vanessa S. Tomasik

College of Graduate Studies: Theses & Dissertations

Adverse Childhood Experiences (ACEs) are widespread and associated with significant and lasting psychological consequences, including posttraumatic stress symptoms (PTSS) and dissociation. Much of the existing literature has focused on adult trauma or narrowly examined childhood abuse and neglect, with comparatively limited attention given to other forms of childhood adversity such as witnessing intimate partner violence, parental separation, or household dysfunction. As a result, the differential psychological impact of distinct types of ACE exposure (i.e., maltreatment vs. household dysfunction) remains insufficiently understood. Emerging literature on coping identifies religious and spiritual (R/S) coping as an important factor in trauma adaptation. Positive R/S …

Telling Her Story, Reclaiming Her Power: A Narrative-Based Group Intervention For Women Impacted By Intimate Partner Violence, Marisa E. Busquets

Psychology Doctoral Specialization Projects

Intimate partner violence (IPV) constitutes a significant public health concern, adversely impacting women’s physical health, psychological functioning, and narrative identity. While existing group interventions, such as The Power to Change manual, provide structured psychoeducational and empowerment-based programming, few adequately address the disruptions to identity and meaning-making processes that often accompany experiences of abuse. The present doctoral specialty project proposes the development of a manualized group intervention for adult women impacted by IPV, grounded in the theoretical and clinical principles of narrative therapy. Narrative therapy conceptualizes identity as an evolving life story shaped by sociocultural and political contexts, and its techniques, …

Bearpaw Reserve Wildlife Monitoring And Mapping With The Wildlands Conservancy, Hope Hansen

Scripps Senior Theses

For my Environmental Analysis Capstone, I worked in a small group to monitor and map the wildlife at Bearpaw Reserve. Bearpaw Reserve, located in Forest Falls, California, is a 600 acre tract of wilderness that is owned by The Wildlands Conservancy. Bearpaw is located about an hour from Claremont, in the San Bernardino Mountains. The Wildlands Conservancy makes management decisions about its reserves while applying conservation research to the real world.

My group’s task was to use trail cameras to gather data on the wildlife at Bearpaw, then visualize this information into a GIS map. We used a combination of …

Embracing Social Media In Identity Exploration And Treatment, Sharon G. Stalions

Psychology Doctoral Specialization Projects

In recent years, Americans are utilizing social media, and particularly video-based social media like TikTok. At the same time, and potentially in response to the ease of access to mental health information online, Americans are increasingly seeking diagnoses. This can be seen not only for mood disorders, but of neurodevelopmental disorders such as attention deficit/hyperactivity disorder (ADHD) and Autism Spectrum Disorder (ASD). Clinicians are no longer the gatekeepers to information on mental health diagnosis, and some communities question the relevance and validity of a professional diagnosis at all. As digital natives become adult therapy consumers, it is important that clinicians …

Braiding More Than Sweetgrass: A Proposed Support Group Model For (Non)Tribal Native Americans In Recovery, Sara Cannon

Psychology Doctoral Specialization Projects

Native Americans (also referred to as American Indian/Alaska Natives or Indigenous persons) have too often been neglected in mental health interventions. This is a disservice, as they are disproportionately affected by challenges such as alcohol use disorder (AUD) and substance use disorder (SUD). Interventions directly speaking to AI/AN culture are rare to non-existent (at least in a published form), with the exception of White Bison’s Wellbriety (White Bison, 2002, 2024). It is not all together uncommon for individuals with Native roots to seek to (re)learn these traditions while in recovery from alcoholism and addiction. The aim of this project is …

The Presence Of Orthorexic Eating Behaviors In Students Studying Health Sciences, Sophia Weiner

West Chester University Graduate Theses, Dissertations, and Final Projects

Orthorexia nervosa is a novel type of disordered eating characterized by a hyper fixation on the consumption of clean, healthy, and morally pure foods as delineated by the individual (Dunn & Bratman, 2016). Previous studies have suggested that individuals studying physical health-related subjects such as nutrition and exercise science endorse more orthorexia nervosa symptoms than those in non-physical health-related areas (Malmborg et al., 2017; Plichta & Jezewska-Zychowicz, 2019). The present study sought to explore the relationship between college major, gender, and levels of body appreciation in the frequency of orthorexia nervosa symptomatology. It also aimed to assess orthorexia nervosa's relationship …

Threaded Belonging: Strengthening Cultural Identity Through Armenian Embroidery In The Diaspora, Krysten A. Lee

Art Therapy | Master's Theses

The current study examined the impact of an Armenian textile arts workshop on cultural identity among members of the Armenian diaspora in the Bay Area of California (n = 25). Grounded in relational-cultural theory, it explored how culturally grounded, community-based, traditional art practices may strengthen cultural identity and reduce cultural disconnection resulting from forced displacement following the Armenian Genocide of 1915. A mixed-methods, arts-based design was implemented where participants engaged in an embroidery workshop centered on traditional Armenian textile practices. Data was collected through pre- and post-intervention Inclusion of Other in the Self (IOS) scale (Aron, Aron, & Smollan, 1992) …

Art As Activism: Emotional Expression And Collective Empowerment Among Muslim Participants Creating Protest Posters, Menhal Sheikh

Art Therapy | Master's Theses

Muslim Americans are among the most underserved populations in mental health care in the United States. In the wake of the ongoing genocide in Gaza, many Muslim Americans have experienced intensified psychological distress, including anxiety, grief, and a heightened sense of helplessness, while continuing to show up in the streets in protest. This mixed-methods study examined whether the collective process of protest poster-making leads to emotional expression among Muslim American participants. Eleven Muslim American participants across two groups in the San Francisco Bay Area completed a pre and post Positive and Negative Affect Schedule (PANAS) to measure changes in affect, …
