Beyond Humor: Code-Switching And Egyptian Modern Identity In Elkabeer Awy., Hala S. Hammad

English Language and Literature

In the stylized Egyptian series ElKabeer Awy, code-switching is an artistic and performative tool by which the writers and actors achieve specific comedic effects and mirror the country's continuous interaction with the global culture. The series employs humor to depict the mixing of Egyptian morals with Western cultural influences. This study implements Poplack's (1980) code-switching categories and Giles' (1979) accommodation theory to analyze characters who code-switch to resemble or differ from their interlocutors. In addition, incongruity theory offers a basis for understanding how some instances of code-switching result in laughter. The results show a high frequency of code-switching among the …

The Representation Of Urban Peripherality In Selected Noir Narratives, Mona Sayed

English Language and Literature

This thesis examines the representation of two forms of urban peripherality, i.e. city periphery and peripheral city, in selected noir narratives from two Akashic short story collections, Brooklyn Noir (2004), edited by Tim McLoughlin, and Mumbai Noir (2012), edited by Altaf Tyrewala. The study investigates these representations to attempt forming a broader conceptualisation of urban peripherality that goes beyond the conventional Western one, which foregrounds the geographical divides as identifying features between urban centre and periphery. The thesis draws on the urban conceptual framework to conduct a close reading of the spatial, cultural, and social representations of urban peripheries within …

Establishing Legitimacy: Analysing Legitimation Strategies In Who’S Anti-Smoking Discourse., Hala S. Hammad

English Language and Literature

Children spend almost one-third of their day in schools, and much of the peer pressure arises in this educational setting. In September 2023, the World Health Organisation (WHO) released two publications to urge schools around the world to take the necessary steps toward creating a smoke and nicotine-free environment and implementing policies that prevent young people from starting smoking. The language of such documents usually conceals a high level of legitimation and persuasion to reach the target audience and achieve the intended goals. Meanwhile, the organisation strengthens its legitimacy when its actions are perceived by the public as desirable, moral, …

The Dynamics Of Arabic Proverbs: A Pragma-Cognitive Study Of Folkloric Proverbs In The Egyptian Series El-Kabeer Awy, Hala S. Hammad

English Language and Literature

This research presents a pragma-cognitive analysis of Arabic proverbs in the Sa'idi (Upper Egyptian) cultural context based on television discourse as its corpus. It investigates proverb usage, their roles in the communication of social norms, and the connections between language, thought, and culture. By employing a pragmatic framework based on Speech Act Theory and the concept of recontextualization, this study examines the use of indirect, culturally loaded speech acts and the endorsement of the local community as a source of metaphor and irony. The results show that the illocutionary force of a proverb is highly dynamic and shifts based on …

From Cinematography To Public Speaking: A Hyland’S (2005) Metadiscourse Model Case Study Analysis Of Spielberg’S Harvard Speech., Hala S. Hammad

English Language and Literature

The study explores the intersection of linguistic metadiscourse and cinematic narrative structure within the genre of public speaking, drawing on Joseph Campbell’s (1949) "Hero’s Journey" as a narrative framework. The paper argues that Steven Spielberg’s rhetorical success is rooted in his ability to direct a live linguistic performance that mirrors the hero’s journey of a film. Utilizing Hyland’s (2005) Metadiscourse Model, the study analyzes Spielberg’s 2016 Harvard Commencement Speech to determine how linguistic markers may function as directorial tools. The study suggests that Spielberg’s strategic placement of interactive markers to construct the Hero’s Journey narrative for the graduates may contribute …

The crisis management systems at Dubai are still ineffective despite the level of technologies …

Enhanced Pulsar Timing Precision For The Era Of Nanohertz Gravitational Wave Astronomy, Sofia V. Sosa Fiscella

Theses

In 2023, several international collaborations comprising the International Pulsar Timing Array achieved a major scientific milestone with the first detection of a signal in pulsar timing observations consistent with the signature expected from a stochastic gravitational wave background, created by an ensemble of unresolved supermassive black hole binaries in the early Universe. The next breakthrough in the field is expected to be the first detection of a continuous wave from a single such binary, which would allow us to better understand their evolution and that of our Universe. However, this feat will require unprecedented precision in our timing measurements. To …

Understanding Computer-Mediated Human Experience In Digital-Physical Hybrid Space, Jiangnan Xu

Theses

With the rapid development of mobile and immersive technologies, the boundary between the digital and real world is increasingly blurred, giving rise to hybrid spaces. Hybrid spaces have permeated daily life and reshaped spatial meaning-making and social interaction. Despite their growing prevalence, empirical understanding of human experiences in hybrid spaces remains limited. If left unexamined, hybrid spaces risk becoming technology-centered rather than human-centered environments that overlook socio-cultural dimensions, potentially leading to harmful consequences for individuals and society. To investigate human experience in hybrid spaces, this thesis comprises five studies and uses gameful systems as research probes. Prior literature identifies collaboration …

Physics-Constrained Generative Adversarial Networks For Dimensionality Reduction In Optimization, Samuel Sisk, Xiaosong Du

Mechanical and Aerospace Engineering Faculty Research & Creative Works

Electric vertical takeoff and landing (eVTOL) aircraft make a unique form of urban air mobility due to their low noise, zero emission, and precision control. To maximize efficiency, high-fidelity simulation-based multidisciplinary design optimization discovers the optimal balance among subsystems within an eVTOL. However, conventional multidisciplinary design optimization is computationally intensive due to excessive high-fidelity model evaluations. Moreover, complex nonlinear constraints deteriorate optimization efficiency and convergence. While surrogate models enable efficient design optimization, surrogate modeling suffers in large-scale applications and surrogate-based optimization still has to deal with nonlinear constraints. To address these challenges, the authors' previous work proposed physics-constrained generative adversarial …

Distributed Vibration Sensing For Identification Of Loose Connectors In Coaxial Data Transmission Lines, Saidanvar Esanjonovich Valiev, Anthony C. Okafor, Jeremiah J. Rittenhouse, Jie Huang, Daniel S. Stutts

Mechanical and Aerospace Engineering Faculty Research & Creative Works

This study investigates the effect of vibration-induced loose connections on signal reflection (S11) for loose connection identification in aerospace coaxial cables using distributed sensing approach, which is effective in filtering the noise and identifying minor discontinuities. In this approach, a sliding gated window is applied to S11 signal, a fast Fourier transform is performed over the gated windows, cross-correlation is computed between the baseline and vibration-affected signals, and the standard deviation is mapped along the cable length. Sinewave signals from 9 kHz to 5 GHz were swept through cables with vibrating connectors under three conditions: fully tightened, loosened by 180°, …

Supersonic Wind Tunnel Free Stream Turbulence Characterization Using 2-Point Focused Laser Differential Interferometry, Joseph Villarreal, Joshua Gary, Davide Vigano

Mechanical and Aerospace Engineering Faculty Research & Creative Works

Non-intrusive laser-based diagnostics, such as Two-Point Focused Laser Differential Interfer-ometry (2-FLDI), play a crucial role in modern aerodynamic research by enabling simultaneous measurements of density and velocity in compressible flows. A 2-FLDI system has been developed and implemented for the Missouri S&T Supersonic Wind Tunnel to characterize free stream turbulence fluctuations and free stream convective velocity. Design choices that enabled the 2-FLDI to overcome low turbulence to measure free stream velocity are detailed. The free stream velocity measurements are validated against previous particle image velocimetry data, showing good agreement. Analysis of normalized velocities and density-based turbulence intensities found that the …

2-Point Focused Laser Differential Interferometry Measurements Of A Parallel Jet In Supersonic Flow, Joshua Gary, Joseph Villarreal, Davide Vigano

Mechanical and Aerospace Engineering Faculty Research & Creative Works

Turbulence in compressible flows plays a central role in applications such as air-fuel mixing in supersonic combustors and is significantly more complex than incompressible turbulence due to the presence of fluctuating thermodynamic quantities. As such, models like the Strong Reynolds Analogy (SRA) are used to relate these quantities. However, SRA validity has been examined primarily in boundary-layer flows. In this work, a newly developed Two-Point Focused Laser Differential Interferometry (2-FLDI) system is implemented in a two-dimensional parallel supersonic jet. The diagnostic is described in detail, including optical alignment procedures, calibration methods, and data analysis techniques. Measurements acquired at multiple streamwise …

Microalbumin Screening In Hypertension: An Evidence Based Implementation, Nicole C. Votaw

Doctor of Nursing Practice (DNP) Scholarly Projects

Introduction

Microalbuminuria is an early indicator of Chronic Kidney Disease (CKD). Hypertension (HTN) is one of the leading causes of CKD. Early treatment of CKD can delay and even prevent progression to End Stage Renal Disease (ESRD). Monitoring patients with HTN more frequently for microalbuminuria can identify CKD earlier than annual screening so that treatment can be initiated sooner to offer greater protection of the kidneys over time.

Background

In a small, rural clinic, it was determined that Urine Microalbumin (UMA) screening in office was not being done, but has been shown to be beneficial in identifying CKD.  Current practice …

Proactive Safety Reasoning In Human-Robot Collaboration In Disassembly Through Llm-Augmented Stpa And Fmea, Morteza Jalali Alenjareghi, Fardin Ghorbani, Samira Keivanpour, Yuvin Adnarain Chinniah, Sabrina Jocelyn

Études primaires

Disassembly tasks in human–robot collaboration (HRC) environments present safety challenges due to hazardous materials, control system variability, and physically demanding operator tasks. To address these challenges, we propose an AI-augmented risk assessment framework integrating System-Theoretic Process Analysis (STPA) and Failure Mode and Effects Analysis (FMEA). This framework is implemented in four configurations: Term Frequency– Inverse Document Frequency (TF-IDF), Fine-tuned Large Language Models (LLMs), Retrieval-Augmented Generation (RAG), and RAG with a structured Knowledge Graph (KG) built from safety standards. The system supports real-time, standards-compliant safety reasoning by generating interpretable, context-specific recommendations. We evaluate these configurations across GPT-3.5 TURBO, GPT-4o, GPT-4.1, and …

Advancing Greenhouse Air Filtration: Biodegradable Nanofiber Filters With Sustained Antimicrobial Performance, Amirali Bajgholi, Reza Jafari, Alireza Saidi

Études primaires

Air quality management in greenhouses is critical to safeguarding plant health and occupational safety, yet conventional filtration methods often fall short in performance and sustainability. These enclosed environments are prone to the accumulation of bioaerosols, including fungi, bacteria, pollen, and dust particles, which can compromise crop productivity and pose health risks to workers. This review explores recent advancements in air filtration technologies for controlled environments such as greenhouses, where airborne particulate matter, bioaerosols, and volatile organic compounds (VOCs) present ongoing challenges. Special focus is given to the development of filtration media based on electrospun nanofibers, which offer high surface area, …

Early Drowsiness Detection Via Second-Order Derivative Analysis Of Heart Rate Variability: A Non-Contact Ecg Approach With Machine Learning, Fabrice Vaussenat, Abhiroop Bhattacharya, Julie Payette, Alireza Saidi, Victor Bellemin, Geordi-Gabriel Renaud-Dumoulin, Sylvain G. Cloutier, Ghislain Gagnon

Études primaires

Drowsy driving contributes to roughly 20% of traffic fatalities, yet most detection systems rely on behavioral cues that appear only after impairment has set in. Here we ask whether first and second derivatives of heart rate variability (HRV) can detect pre-crash states earlier than conventional approaches. Twenty-five participants completed 49 driving simulator sessions while we recorded cardiac activity through capacitive ECG electrodes embedded in the seat backrest—a non-contact method that avoids the privacy concerns of camera-based monitoring. To prevent circular evaluation, ground truth labels were based solely on crash proximity rather than HRV-derived scores. The combined HRV feature set (conventional …

Academic studies demonstrate substantial progress in detection accuracy, real-time processing, trajectory tracking, and predictive risk assessment through deep learning …

Moral Progress In Legal Doctrine, Philip Petrov

Faculty Scholarship

This article integrates the concept of moral progress – here, moral improvement in the thinking and behavior of individuals over time – into the study of legal doctrine. The article first presents a naturalistic account of what moral progress is and describes three of its most historically and analytically important forms: (1) moral circle expansion, (2) moral domain expansion, and (3) increasing sensitivity to proportionality. The article then analyzes three historical developments in U.S. tort law that qualify as instances of moral progress: (1) the partial demise of the “suicide rule” beginning around the 1980s (according to …

Digital Assets And The Property Question, Andrea Tosato, Christopher K. Odinet

Faculty Scholarship

Is crypto property? The proliferation of digital assets such as cryptocurrencies, stablecoins, memecoins, and NFTs has confronted legal systems worldwide with three interdependent challenges: determining whether they are property, identifying their appropriate classification within property taxonomies, and establishing rules for their circulation in commerce. Our Article addresses this tripartite question—the Property Question—within American law.

The stakes here are significant. Billions of dollars in digital assets are traded daily, used as collateral, and held by custodial platforms. Yet all these transactions rest on an unresolved premise: that digital assets can be owned and are governed by established property rules. This fundamental …

The MTT assay, soft agar colony formation, Matrigel invasion, and nude mouse xenograft models were applied to assess oncogenic properties. Patient survival was analyzed using the log-rank …

Proliferative Glomerulonephritis With Monoclonal Immunoglobulin Deposits With Severe Acute Kidney Injury Successfully Managed By Clone-Directed Therapy: A Case Report, Shohei Maekawa, Shinya Yamamoto, Tatsuaki Kosaka, Hisashi Kamido, Yasuyuki Arai, Yayoi Ogawa, Naoka Murakami, Yuki Teramoto, Motoko Yanagita

Faculty, Staff and Students Publications

Introduction

Proliferative glomerulonephritis with monoclonal immunoglobulin deposits (PGNMID) is a form of monoclonal gammopathy of renal significance, characterized by kidney injury caused by monoclonal immunoglobulin deposition in the glomeruli. While detectable clones are only found in 20–30% of PGNMID, plasma cell- or B-cell-targeting therapies are suggested to be effective. Recent case reports suggested immune dysregulation, such as viral infections or vaccinations, could potentially trigger the onset or relapse of PGNMID. Here, we report a case of PGNMID without detectable clones, which relapsed after viral enteritis, presenting with severe acute kidney injury (AKI) and nephrotic syndrome.

Lysine Demethylase 4a Is A Centrosome-Associated Protein Required For Centrosome Integrity And Genomic Stability, Pratim Chowdhury, Xiaoli Wang, Richard I Han, Manga Motrapu, Ashley G Boice, Yuya Nakatani, Sofia Vargas-Hernandez, Julia F Love, Claude Chew, Sandra L Grimm, Dereck Mezquita, Frank M Mason, Elisabeth D Martinez, Cristian Coarfa, Cheryl L Walker, Anna-Karin Gustavsson, Ruhee Dere

Faculty, Staff and Students Publications

Centrosomes play a fundamental role in nucleating and organizing microtubules in the cell and are vital for faithful chromosome segregation and maintenance of genomic stability. Loss of structural or functional integrity of centrosomes causes genomic instability and is a driver of oncogenesis. Here we identify lysine demethylase 4A (KDM4A), an epigenetic 'eraser' of chromatin methyl marks, as a centrosome-localized protein, visualized at the nanometer-scale resolution. We additionally uncovered that KDM4A demethylase enzymatic activity is required to maintain centrosome homeostasis and integrity; a previously unknown functionality unlinked to altered expression of genes regulating centrosome number. We find that KDM4A interacts with …

Computational Insights Into Orthotropic Fracture: Crack-Tip Fields In Strain-Limiting Materials Under Non-Uniform Loads, Saugata Ghosh, Dambaru Bhatta, S. M. Mallikarjunaiah

School of Mathematical & Statistical Sciences Faculty Publications

A finite element framework is presented for analyzing crack-tip phenomena in transversely isotropic, strain-limiting elastic materials. Mechanical response is characterized by an algebraically nonlinear constitutive model, relating stress to linearized strain. Non-physical strain singularities at the crack apex are mitigated, ensuring bounded strain magnitudes. This methodology significantly advances boundary value problem (BVP) formulation, especially for first-order approximate theories. For a transversely isotropic elastic solid with a crack, the governing equilibrium equation, derived from linear momentum balance and the nonlinear constitutive model, is reduced to a second-order, vector-valued, quasi-linear elliptic BVP. This BVP is solved using a robust numerical scheme combining …

The Lived Experience Of Pediatric Pain Management: Insights From Families And Providers, Samrithaa Balakrishnan, Annesha Dey, Aarti Bavare, Paul Checchia, Katherine Shwetz, Natasha Afonso

Faculty, Staff and Students Publications

Pain represents a subjective experience that manifests with emotional and physical discomfort. In pediatric care, pain management is especially complex due to communicative limitations, which creates a unique point of entry for parents to contribute to their child's treatment process. In this study, we explored whether families' perceptions of their child's pain and preferences for treatment were aligned with healthcare providers' pain management decisions. Using narrative-informed techniques in interviews with families and healthcare providers in pediatric care settings, we analyzed areas of concordance and discordance in pain assessment and treatment priorities. Our findings show that trust is built over time …

A Conceptual Framework For Cognitive Engagement And Human Agency In Ai-Mediated Learning, Sam Rhodes, Zuhal Yilmaz, Terrie Galanti, Younggon Bae, Victoria Delaney, Zareen Gul Aga, Stephen Hutt

School of Mathematical & Statistical Sciences Faculty Publications

The purpose of this chapter is to propose a conceptual framework that unpacks AI use in instructional practice across three interrelated dimensions: human agency, cognitive demand, and AI orchestration. We ground this work in historical perspectives on technology's mediating role in education. We then propose the conceptual framework and three characterizations of the use of AI in school instruction: cognitive load reducer, cognitive capacity builder, and cognitive companion. We then illustrate a worked example of each, including a curricular example and sample student prompts, and conclude with questions that educators might ask themselves as they consider if and how to …
