Moving beyond technology-centered theories of digital transformation, this thesis examines the institutional and governance factors shaping digital public service delivery in Egypt. It analyzes how governance structures, data governance arrangements, and interoperability frameworks influence the extent to which digital transformation initiatives result in integrated, scalable, and citizen-facing public services. Using a qualitative research design, the study draws on an analysis of relevant policy and program documents and semi-structured interviews with key stakeholders involved in digital transformation initiatives in Egypt. The findings indicate that persistent challenges in digital public service delivery are driven less by technological constraints than by fragmented governance …

What Are The Factors Affecting The Financial Sustainability Of Social Enterprises In Egypt?, Mina Atta Ghaly

Theses and Dissertations

This thesis investigates what factors affect the financial sustainability of social enterprises (SEs) in Egypt, situating them within a constrained MSME, legal and sectoral context marked by informality, weak innovation and recurrent shocks. Drawing on global and Egyptian literature, it identifies ten candidate factors—business model, financial management, founders’ skills and mindset, revenue structure, sector and mission, legal framework and innovative finance, capacity building, investment mechanisms and “the right investor”, adaptability to shocks, and ecosystem conditions—and integrates them into an extended Social Enterprise Model Canvas. Using a qualitative, exploratory design with semi‑structured interviews of social enterprise founders, incubators/accelerators, investors and experts, …

Structural Relationships Between Classroom Social Climate, Affective Factors And Willingness To Communicate Among International Mandarin Learners In Shandong, China, Muzi Li

Student Works (2020-2029)

This study addresses a critical gap in second language acquisition (SLA) research by investigating effects of classroom social climate (CSC) and affective factors on willingness to communicate (WTC) in both non-digital and digital contexts among international Mandarin learners. Although L2 Mandarin is expanding globally, limited research has examined the joining effects of CSC and affective factors on WTC across different learning environments. Employing a cross-sectional correlational dedign based on Self-Determination Theory and Broaden-and-Build Theory, data were collected from 390 L2 Mandarin learners in Shandong province, China, with 360 valid responses. Structural equation modeling (SEM) was employed to analyze the relationships …

Comparative Evaluation Of Conventional And Sustainable Concrete Protective Coatings: Performance, Economic, And Environmental, Andro Ebrahim

Theses and Dissertations

Concrete structures are highly susceptible to deterioration from environmental, chemical, and mechanical factors, making protective coatings essential for ensuring durability and reducing maintenance demands. This study aims to compare and evaluate conventional and innovative coating systems for concrete protection across three dimensions—technical performance, environmental sustainability, and life cycle cost efficiency—and to assess whether coatings often regarded or marketed as sustainable genuinely achieve sustainability across these three pillars. Four representative coatings were selected for assessment: epoxy solvent-based, epoxy solvent-free, acrylic water-based, and cementitious. Technical performance was examined through laboratory testing, expert interviews, and multiple real project cases, providing a comprehensive understanding …

Gender, Integration, And Labor Market Access: The Case Of Syrian Refugees In Germany, Feras Al-Mekhlafy

Theses and Dissertations

Germany hosts one of the largest populations of Syrian refugees in Europe, making their successful labor market integration critical for social and economic stability. This study investigates the gender gap among Syrian refugees in Germany within the broader refugee–native labor market gap. Using cross-sectional data from the 2022 SOEP refugee survey, it applies a Heckman two-step selection model to jointly analyze employment and wage outcomes while correcting for selection bias. Results reveal that structural barriers (e.g.: legal and bureaucratic) and compositional factors (e.g.: human capital) rather than wage discrimination drive most observed disparities. Female refugees face significantly lower employment probabilities, …

Inspect: Intelligent Node-Based System For Ifc Processing And Evaluation, With Conversational Tool Support —Llmassisted Natural Language Ifc Querying, Basel Abdelshaheid

Theses and Dissertations

Industry Foundation Classes (IFC) enables the open exchange of Building Information Models, yet effective validation of real-world IFC deliveries remains challenging. Project models frequently contain incomplete, inconsistent, or incorrectly exported metadata, and explicit IFC relationships are often missing or degraded during conversion from proprietary formats. Many validation questions are inherently spatial, including connectivity, containment, proximity, and clashes, and therefore cannot be answered reliably from properties alone. As a result, federated model validation is often slow, fragmented across tools, and dependent on specialized IFC expertise.

This challenge is increasingly important for coordination, quality assurance, and information management across disciplines and lifecycle …

Groove Goes The Distance: An Initial Inquiry Into Jazz Music In Egypt, Farida Gohar

Theses and Dissertations

Jazz music has been a historically contentious site of social, cultural, and political signification. From the violent subjugation that characterized its origins and aspirational freedom that animated its practice, to its transformation into a distinctly “American” music instrumentalized by the US State Department to counter Soviet influence, jazz’s capacity for the inscription of meaning is vast and regularly cause for debate. The particular configuration of jazz music in Egypt is no less complicated although seldom studied. This thesis ventures an initial mapping of the dynamics and negotiations that historically defined the initiation of “Egyptian” jazz, as well as the ones …

Uncovering Potential Therapeutic Targets For Spinal Cord Injury; Insights From Single-Cell And Cross-Species Transcriptomics, Sara Samy Abouzekry

Theses and Dissertations

Central nervous system (CNS) injury remains a devastating healthcare problem. Despite years of research, it remains almost impossible to achieve meaningful functional repair following traumatic brain injury (TBI) and spinal cord injury (SCI). Spinal cord injury (SCI), a highly devastating subset of CNS trauma, is considered a challenge due to the extremely limited regenerative capacity of the nervous system in adult mammals. In contrast, certain species display remarkable repair abilities followed by moderate regenerative ability in neonatal mammals, indicating that regeneration is shaped by the evolutionary context as well as the developmental age.

To uncover the core molecular mediators of …

Security In The Arctic: The Decline Of Arctic Exceptionalism? Between Cooperation And Militarization, Victoria Berg Hagen

Theses and Dissertations

The Arctic has been understood as a region separated from international relations, where states choose to collaborate and maintain stability (Gjørv et al. 2020: 2). This has led to the creation of the concept of “Arctic Exceptionalism” (Heininen 2019: 226). Currently, the Arctic is becoming strategically important. Furthermore, the region is witnessing militarization and increased international tensions affecting the Arctic states (Padrtova 2020: 38). This thesis analyzes how Arctic exceptionalism, as reflected in bilateral relations (specifically Russia-Finland and Russia-Norway), has been impacted by the Donbas War, the invasion of Ukraine, and militarization in the Arctic by both NATO and Russia. …

Does Increasing Human Impact Across The Holocene Result In Simplification Of Vegetation Composition And Diversity Across Europe? A Pollen-Based Spatio-Temporal Approach, Caterina Röhm, Maria Antonia Serge, Ralph Fyfe, François Gillet, Laurent Marquer, Agnès Lagnoux, Thierry Klein, Didier Galop, Florence Mazier

School of Geography, Earth and Environmental Sciences

Land use and climate change are the primary drivers of current biodiversity loss, but have had different impacts on biodiversity across the Holocene epoch. To enhance our understanding of current changes in diversity and its impact on ecosystem functions, knowledge of long-term interactions between vegetation diversity, land use change, and climatic change is crucial. Grid-cell estimates of quantified regional vegetation cover (RV_est) based on pollen data from 1607 sites across Europe, transformed using the REVEALS (Regional Vegetation Estimates from Large Sites) model, have been used to explore spatiotemporal changes in vegetation and regional diversity during the Holocene (25 …

Characterizing Indoor Surface Voc Contamination After The 2025 Los Angeles Fires, Brett W. Stinson, Emily Lei, Elliott T. Gall

Mechanical and Materials Engineering Faculty Publications and Presentations

We quantify volatile organic compound (VOC) emissions from indoor surface swabs and portable air cleaner (PAC) filters collected in a home 30 days after the 2025 Los Angeles wildland-urban interface (WUI) fires. We calculate emissions for 17 fire-relevant compounds. Surface emissions exceeded those of clean controls, and emissions from a windowsill in a room without a PAC were ∼15× and ∼2× higher for benzene and toluene, respectively, than rates reported in the literature for comparable materials unaffected by smoke/soot. Particle filters installed in PACs at the start of the fire emitted aromatics at rates comparable to those reported in a …

Spatial Abilities In Aging Adults With Down Syndrome, Yingying Jennifer Yang, Romal Bhullar, Sonia Conde

Department of Psychology Faculty Scholarship and Creative Works

INTRODUCTION

People with Down syndrome (DS) have a higher likelihood of developing Alzheimer's disease (AD). Deficits in spatial abilities could serve as early indicators of AD. We examined age effects on visuospatial construction and visuomotor integration in DS and whether spatial tasks could distinguish various extents of cognitive decline in DS.

METHODS

We used the Alzheimer's Biomarkers Consortium–Down Syndrome project dataset, where 376 DS participants completed a series of cognitive measures.

RESULTS

Age effects were found in visuomotor integration but not in visuospatial construction. Both abilities declined with AD progression. While both abilities showed relatively poor discrimination between cognitively stable …

Integrating Future Factory-To-Factory (F2f) Manufacturing Through System Of Systems Engineering (Sose): A Framework For Capability Beyond Constituent Systems, Polinpapilinho F. Katina, Hengtao Tang Ph.D., Anouar Hallioui

Faculty Publications

System of Systems Engineering (SoSE) is an emerging discipline focused on the design, integration, and evolution of metasystems—composed of multiple autonomous yet interdependent systems. These systems of systems (SoS) offer capabilities that exceed those of any individual constituent systems by enabling synergistic coordination, interoperability, and dynamic adaptation across diverse operational contexts. This study pursued three primary objectives: (i) to examine the role of integration in enabling emergent capabilities beyond those of individual systems, (ii) to explore SoSE as a framework for orchestrating Future Factory-to-Factory (F2F) Manufacturing, and (iii) to assess the implications of SoSE to address volatile, uncertain, complex, and …

Muscle Endurance Exercise Training Improves Health Factors In Middle Aged Individuals, Gregory Wallace

Doctorate in Kinesiology

This study examined the effects of an eight-week Muscle Endurance Exercise Training (MEET) program on body composition (BC), cardiorespiratory fitness (CRF), and muscle endurance (ME) in healthy adults. Thirty-one participants (M_age = 39.03 ± 13.82 years) completed pre- and post-intervention assessments of body mass index (BMI), body fat percentage (BF%), waist-to-hip ratio (WHR), CRF via the 3-minute YMCA Step Test, and ME using push-up and sit-up tests to failure. Paired-samples t-tests and Wilcoxon signed-rank tests were used to determine statistical significance. Results revealed no significant change in BMI (p = .103), while BF% (p = .020) and WHR (p = …
