Between Reform And Dependency: Ifi Influence On Egyptian Food Sovereignty, Nayera Ayman Abouelfarh

Theses and Dissertations

This thesis examines how international financial institutions (IFIs), particularly the International Monetary Fund (IMF) and the World Bank, have influenced Egyptian food sovereignty between 2016 and 2024. It asks how IFI-backed structural adjustment programs, policy influence, and ideational influence reshaped Egyptian public policy and affected the state’s capacity to autonomously manage its food system. The thesis argues that IFI-driven reform agendas prioritized macroeconomic stabilization, fiscal discipline, and export-oriented growth over food sovereignty, increasing Egypt’s external dependence and vulnerability to global market shocks. Methodologically, the study employs a qualitative comparative case study design combining process tracing and thematic document analysis using …

Thematic analysis revealed six interconnected themes: (1) describing the father’s role, (2) learning the father role, (3) social and cultural influences on the father role, (4) meaning of being a father, …

The Paradox Of Palestinian Exile: Unrwa, Structural Limbo, And The Manufactured Crisis Of The Right To Return, Laila Ibrahim Hassan Elkassas

Theses and Dissertations

This thesis argues that the temporariness of Palestinian exile has been turned into a manufactured limbo that is sustained by international law, humanitarian governance and host- country regimes. It uses General Assembly Resolution 194 and the broader human rights regime to show how the right to return is constantly reaffirmed but structurally postponed, resulting in a gap between legal promise and political reality. Drawing on Edward Said’s notion of exile as an unhealable rift, Pierre Bourdieu’s concept of habitus and Didier Fassin’s thinking on humanitarian reason, the thesis constructs a multi-scalar framework that conceptualizes limbo as existential experience, embodied practice …

An Integrated Sensor-Fusion Framework For Performance-Based Compensation In Construction, Aly Ayman El-Ashry

Theses and Dissertations

Construction productivity has historically stagnated due to a reliance on subjective labor monitoring and “lagging” performance indicators. This research proposes a novel compensation model with the use of Total Energy Management System (TEMS) to translate labor effort and efficiency into payment incentives with the integration of Internet of Things (IoT) wearables and Statistical Process Control (SPC) charts.

This research addresses the systemic problem of declining construction productivity caused by industry’s inability to objectively quantify human effort. While traditional models rely on post-facto production tallies, a significant research gap exists in real-time physiological labor monitoring. To bridge this, the proposed TEMS …

Testing The Moderating Effect Of Self-Compassion On The Relationship Between Perfectionism-Related Discrepancy And Perceived Social Support From Family, Marinne Hammond

Theses and Dissertations

Perfectionism involves an insistence on outstanding performance on tasks to an extreme level. More specifically, perfectionism-related discrepancy is when one subjectively sees a gap between their performance and their expectations for how they should perform. Perfectionism may be linked to mental health issues, such as anxiety, depression, eating disorders, and social disconnection. The perfectionism social disconnection model asserts that perfectionism can also lead to social withdrawal. Self-compassion involves the acceptance of imperfection; it has been associated with higher perceived social support and has also been shown to attenuate the relationship between perfectionism and psychological distress. This study aimed to further …

Modeling The Spread Of Competing Narratives In Multimodal Social Media Network, Mayor Inna Gurung

Theses and Dissertations

Social media has fundamentally transformed how narratives are produced, contested, and disseminated, enabling competing interpretations of the same event to spread rapidly across networked populations. Understanding how narratives gain traction over others in these environments is critical for addressing misinformation, supporting informed public discourse, and designing effective counter-messaging strategies. Yet existing research largely treats narrative propagation as a single-process phenomenon and focuses predominantly on textual data, overlooking both the competitive dynamics between opposing narratives and the growing role of visual symbolic communication in shaping how narratives are received. This dissertation addresses these gaps through a multi-platform, multimodal framework applied to …

Participants experienced compounded RBF due to advocating for students (i.e., speaking out, supporting, or intervening). Participants’ most perceived psychological stress response to RBF was racism awareness, and most perceived behavioral stress response was spirituality or religion. Participants disrupted the impact of RBF through intrinsic care (i.e., purpose or why, managing emotions, and self-care) and …

Turning Boycott Into A Sustainable Opportunity: Leveraging Boycott To Boost Local Production And Enhance Local Market Competitiveness In Egypt, Alaa Maher

Theses and Dissertations

While existing literature largely concentrates on the consumer behavior dimensions of boycotts, limited attention has been paid to their structural economic implications for FDI and local production. This paper frames the 2023 boycott campaign as a demand shock in Egypt’s food and beverages sector. Dependency theory is applied to assess the pre-boycott stage, where MNCs’ market power created structural dependencies within the sector. Dynamic capabilities theory is employed to explain the heterogeneity in firm responses during the boycott and their attempts to acquire sustainable market share. Using a multi-case study design, qualitative in-depth interviews were conducted across 16 firms in …
