Impact Of An All-Gender Cabin Intervention At A Residential Summer Camp On Self-Esteem And Perceived Social Support In Lgbtq+ Youth, Suzanne D. Dinubile

Doctoral Dissertations

This study is a program evaluation with a mixed-methods design that evaluated the impact of Camp Tawonga’s All-Gender Cabin Intervention and LGBTQ+ programming showed no statistically significant changes, likely due to small sample size, but descriptive trends indicated improved outcomes for LGBTQ+ youth in All-Gender cabins. Semi-structured interviews with six LGBTQ+ campers revealed increased self-awareness and acceptance, empowerment, self-confidence, and a stronger sense of belonging within the LGBTQ+ community, along with positive interactions with non-LGBTQ+ peers. Notably, the three campers in All-Gender cabins highlighted unique themes of identity affirmation, emotional and behavioral growth, and relief from minority stress. Findings support …

Political Uncertainty And Firm-Level Stock Market Reactions In The United States, Nozomi Tanaka

Honors Program: Senior Projects (Public)

Political uncertainty has become an increasingly important feature of the global economy, with major geopolitical events often triggering rapid reactions in financial markets. This study examines how geopolitical shocks affect firm-level stock market performance in the United States. Using an event study framework, the analysis evaluates cumulative returns and stock return volatility for fourteen publicly traded firms across nine major geopolitical events between 2016 and 2022, including the Brexit referendum, the U.S.–China trade war, the COVID-19 pandemic, and the Russia–Ukraine war.

The results indicate that most firms experienced negative abnormal returns around geopolitical events, suggesting that political uncertainty is generally …

Artificial Intelligence And Translation: Exploring Current Applications, Limitations And Future Potential Of Language Models Through Japanese-English Translation, Loklin Elias Nord

Undergraduate Theses, Capstones, and Recitals

This thesis highlights the recent improvements and capabilities of Large Language Models (LLMs), specifically their ability to produce translations between different languages. The continued up-scaling of model sizes has led to breakthroughs in the level of their observed intelligence, allowing them to produce translations that are similar in quality to highly skilled human translators. However, to facilitate the reasoning processes that LLMs now possess, their demand for computational power and the supporting hardware and resources has increased proportionally. Considering the impacts of this technology on the environment, energy resources, and its accessibility, my research explores the possibilities of smaller, highly …

Occupational Exposure, Biomarker Profiles, And Safety Practices Among Egyptian Pesticide Factory Workers, Mireille M. Hanna

Theses and Dissertations

Background: Pesticide factory workers represent a critically understudied occupational population in Egypt, where existing literature has focused predominantly on agricultural field workers and spray teams, leaving the industrial manufacturing workforce virtually uncharacterized. Despite the potential for continuous, year-round, high-intensity mixed chemical exposure in factory settings, no contemporary comprehensive study has examined the multi-system health correlates of pesticide exposure among Egyptian factory workers.

Aim: This study aimed to assess the occupational health correlates of pesticide exposure among factory workers across neurological, hematological, hepatic, renal, endocrine, and reproductive outcomes, and to evaluate the role of exposure intensity, personal protective equipment use, safety …

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, …

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 …

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 …

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, …

Co-Creation Of Classroom Language: Supporting Learners To Develop Expressions Of Uncertainty And Statistical Concepts, Jioo Nimkar, Nayanatara Ruth Gautham

The Mathematics Enthusiast

This qualitative study explored how Grade 4 students and the researcher co-created language to express statistical concepts in a multilingual Indian classroom during a week-long instructional sequence. The analysis draws on a situated socio-cultural perspective on language in mathematics. Students’ language progressed from simple claims to more refined and sophisticated expressions, enabling them to discuss central tendencies and distributions while acknowledging uncertainty. Co-created phrases such as āsapās reshā (the nearby line) not only supported communication but also deepened reasoning. The article also discusses what role scaffolding played in refining these informal resources.

Evolution Of Pre-Service Teacher Beliefs Along The Traditional-Reform Continuum: An Examination Of Normative Beliefs And Discursive Claims A Decade Later, Mary Elizabeth Riley Lloyd, Adam Jordan

The Mathematics Enthusiast

This study replicated an earlier study that explored the beliefs of a sample of K-8 pre-service teachers (PSTs). Results of this study position PSTs’ beliefs along a traditional-reform continuum. The positioning from the current study is compared to that of the former study, to determine the level of progress made toward the National Council of Teachers of Mathematics’ commitment to high-quality instruction. To position beliefs, PSTs completed a Likert survey, including open-ended questions, three times throughout their teacher preparation program (TPP): before taking any of their mathematics education courses, after taking both required mathematics education courses, and after student teaching. …

Multimodal Interpretation Of Notation, Dave Hewitt, Jenni Ingram

The Mathematics Enthusiast

Challenges related to the teaching and learning of formal notation in school mathematics are widely documented, and specifically in relation to the underlying mathematical structures that the notation is intended to convey. In this article, we draw on embodied cognition to examine the interactions among three students working with the software Grid Algebra. Embodied cognition emphasises the role of gesture and movement in learning and understanding mathematics. Grid Algebra uses movement to direct students’ attention to mathematical operations on numbers and numerical expressions within the grid and the structure of these operations, while the software takes care of the …

The Mathematics Enthusiast

This paper presents the findings of a study, conducted as part of a PhD thesis, exploring ways in which translanguaging can be used to support the development of conceptual understanding of division. The study focused on 18 8-9-year-old pupils learning mathematics through the instructional languages of English and French in an ‘immersion-style’ bilingual education context in England. The data was collected from four consecutive mathematics lessons focusing on division, the first two taught through English by a monolingual English teacher and the second two taught in French by a bilingual French teacher. Both teachers were interviewed directly following their second …

Pre-Service Teachers’ Noticing Of The Function Of Mathematical Naming In The Teaching Of Fractions, Juan Manuel González-Forte, Núria Planas

The Mathematics Enthusiast

In this paper, we present the rationale and results of a study conducted with 79 pre-service primary-school teachers on their sensitivities to notice the pedagogic function of naming practices in the language of teaching fractions. Our results are a contribution to noticing research on mathematics teacher education and language. Although participants were not familiar with discussions of the language of teaching mathematics in general and the language of teaching fractions in particular, they engaged in an intervention with a professional task that provided opportunities to notice potential relationships between mathematical naming and the conceptual understanding of fractions. The written answers …

From Words To Worlds: Concluding Reflections And Emerging Directions, Jenni Ingram, Núria Planas, David Pimm

The Mathematics Enthusiast

In concluding the second series of eight articles in the double special issue on ‘Engaging with communication and language in relation to mathematics and its education’, we take the opportunity to reflect across the articles to prompt us all to consider potential and emerging directions for future research. This final article is overall a commentary inspired by the communication-centred and language-centred contributions to mathematics education across the entire collection of articles, that is, all those comments that situate mathematics and its education as language and communication praxis. We explore this relationship between mathematics and its education with communication and language …

An Analysis Of The Pedagogical Price Of Mathematical Tricks: The Case Of Factoring, John Beam, Jason Belnap, Eric Kuennen, Amy Parrott, Jennifer E. Szydlik

The Mathematics Enthusiast

Students are exposed to a variety of mathematical tricks that ostensibly make it easier for them to solve problems. But tricks also undermine their understanding that mathematics is supposed to make sense; they rob students of opportunities to explore and struggle with ideas; and they obscure mathematical structure.

Affordances For Graphical Shape Thinking Through Vivid Informal Classroom Talk, Elizabeth Kimber, Cathy Smith

The Mathematics Enthusiast

The shape of a graph arising from the covariation of variables is a crucial idea in reasoning about functions and graphs. Students’ perspectives on graph shape may foreground visual features and consider the shape to be a fixed property of the function (static graphical shape thinking). In contrast, students can perceive the graph as a trace of covarying quantities, through which its shape arises (emergent graphical shape thinking). It is of interest to understand how these perspectives are supported and promoted by teachers in classroom discourse. We present findings from a study of classroom discourse in which we used systemic …

From Uncertainty To Dialogue: Visualising Collaborative Noticing And Mathematical Intuitions In Students' Narratives Within Probability Learning, Daniela Diaz-Rojas

The Mathematics Enthusiast

This study explores the critical role of language and communication in fostering collaborative noticing practices that display mathematical intuitions within probability learning. Through an analysis of student interactions, I show how the joint articulation of ideas and the exploration of shared doubt enable intuition, often perceived as an object that is held and a solitary experience, to become a socially shared and co-constructed process. The observed collaborative dialogue concerns shared content and form, constructing a joint narrative architecture that enables common understanding and allows the group to notice, examine, and reshape their intuitions. Collaborative noticing when working with probability problems …

Teachers’ Knowledge And Use Of Mathematics Register For Teaching And Communication, Pauline Tiong, Sheena Tan

The Mathematics Enthusiast

Research has progressively considered a resource-oriented rather than a deficit-based approach towards understanding the role of language in helping students learn mathematical concepts. Notably, there has been a call for greater attention to the notion of mathematics teaching talk, which focuses on teachers’ use of language as a resource to teach mathematics (and the language of mathematics). It is argued that mathematics teaching talk plays an important role in enabling teachers to communicate mathematical ideas or meanings of mathematical concepts and in turn, preparing students to participate better in mathematical discourse practices. Specifically, this paper seeks to exemplify what teachers …

Affectivity As A Form Of Communication During Interactions Between Parent, Child, And Touchcounts, Qiang Lin

The Mathematics Enthusiast

This qualitative study examines communication in family mathematics settings, focusing on how embodied communication is constituted during parent–child interaction with a multitouch technology application, TouchCounts. Moving beyond information–transmission perspectives, the study adopts an embodied and relational approach centered on affectivity—conceptualized as the circulation of attunement, resonance, and intensity of movement and feeling across human and non-human components of the parent–child–TouchCounts assemblage. Drawing on close qualitative analysis of two selected video-recorded excerpts, the study traces how mathematical events unfold moment by moment through bodily action and material engagement, and how affective flow shapes how participants respond to one …

Book Review: Irrationality, Transcendence And The Circle-Squaring Problem: An Annotated Translation Of J. H. Lambert’S Vorläufige Kenntnisse And Mémoire (2nd Ed.), Bharath Sriraman

The Mathematics Enthusiast

This review examines Irrationality, Transcendence and the Circle-Squaring Problem (2nd ed., 2024) by Eduardo Dorrego López and Elías Fuentes Guillén, offering the first complete annotated English translations of Johann Heinrich Lambert’s two foundational texts on the irrationality of π: the semi-popular Vorläufige Kenntnisse (1766/1770) and the rigorous Mémoire (1761/1768). The review situates these translations within Lambert’s remarkable and largely underappreciated life—a self-taught polymath who rose from a tailor’s workshop in Mulhouse to the Berlin Academy of Sciences—and gives careful attention to the proof of irrationality of π via continued fractions, placing it in dialogue with the Niven–Hermite integral approach, the …

Book Review: Mathematical Geography In The Eighteenth Century: Euler, Lagrange And Lambert, Bharath Sriraman

The Mathematics Enthusiast

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 …

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, …

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 …

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 …

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 …

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, …
