Is It Time To Reconsider Plant Populations Of Top Mississippi Corn Hybrids?, Jason Kober

Theses and Dissertations

In Mississippi (MS), a 5.6 Mg ha-1 yield gap exists between the potential and actual corn (Zea mays L.) grain yield. The disparity underscores unrealized yielding potential of modern hybrids under current agronomic management practices. This study evaluated the yield response of four commercially grown top performing hybrids planted at five plant densities (6.2, 7.4, 8.6, 9.9, and 11.1 plants m-2) across four locations in MS over two years. Grain yield and kernel weight were subject to analysis of variance. The analysis was performed two ways: hybrid-level analysis (HA) using two hybrids common across all site-years, and location-level analysis (LA) …

No-Till Versus Conventional Tillage Cover Crop Systems Effects On Cotton In The Blackland Prairie Region Of Mississippi, Mallie West Rivenbark

Theses and Dissertations

Nitrogen (N) plays a critical role in cotton production systems. Management practices such as tillage systems and cover crops (CC) can influence nutrient cycling and availability within the soil. The present study assessed the effects of CC in a conventional tillage (CT) vs. no-tillage (NT) system on cotton yield, fiber quality and N use efficiency. Ramifications for CC and N rates on lint yield and cotton N uptake were investigated during the 2024 and 2025 growing seasons in Verona, MS. Cover crop treatments include cereal rye (Secale cereale), crimson clover (Trifolium incaranatum) and a mix of cereal rye and crimson …

Contested Surveillance: Gendered Citizenship And Political Participation In Egypt And Lebanon, Mohamad Zarif

Theses and Dissertations

While the 2011 Arab Uprisings were famously framed by the utopian narrative of a 'Facebook Revolution', this view has given way to a dystopian reality in which digital infrastructures can facilitate authoritarian retrenchment. This thesis interrogates how lowermiddle- and working-class precarious youth navigate and perceive this "Architecture of Control" in Cairo and Beirut. Using a comparative qualitative design with purposive and snowball sampling, this research integrates digital ethnography and fourteen interviews with eighteen participants (nine women, seven men) to capture lived experiences of surveillance rather than the internal logic of state security institutions. The study yields three primary findings. First, …

A Governance-Aware Multi-Agent Framework For Enhancing Fairness & Temporal Accuracy In Disaster Response Systems, Md. Ashfaqur Rahman

Theses and Dissertations

Large Language Models (LLMs) have demonstrated significant potential in disaster-response decision support, however, their deployment in high-stakes humanitarian settings raises critical concerns regarding factual reliability, fairness, temporal validity, and governance compliance. Hallucinated outputs, demographic bias, and outdated recommendations can directly impact vulnerable populations and undermine public trust. This dissertation proposes a governance-aware multi-agent framework designed to enhance fairness and temporal accuracy in disaster-response systems through structured Retrieval-Augmented Generation (RAG), verification-driven orchestration, and adaptive correction mechanisms.The proposed architecture decomposes response generation into specialized agents responsible for real-time retrieval, fact-checking, bias auditing, temporal validation, threshold-based correction, and monitoring. By embedding governance constraints …

Catalyst, David Steck

Theses and Dissertations

Catalyst is a short documentary that explores why Hip Hop happened much later in Chicago than in other cities. It focuses on the story of Duro Wicks, a young Black music lover who overcame the city’s segregation to launch the first weekly Hip Hop open mic night. At the weekly $3 Sunday Hip Hop Show held at the Lower Links, young people came together from across the divided city to create a community. Though more successful than anyone could have imagined, Wicks’ dream proved unsustainable. However, it forever transformed the lives of the people it touched and launched a sustainable …

Notes On Rhythm, Maya Lee-Parritz

Theses and Dissertations

Line meets impulse, association meets sign. I weave the eye towards the smudge and sublime—a fractal lineage flowing through the brush, my body, space itself. I walk toward reality in serial successions, allowing what is fragmentary to move me, to cohere in shards, murky and strange inside of me. My body is a repository of images, of broken rhythms and dissonant ideologies. All of these flow and stutter onto the surface, dripping and blurring over each other. Through all of this, I always try to make something whole, perfect, and true.

Fishing, Butchery And Smoking: Salmonids In Northeastern Iceland, Quinn Matthew Habedank

Based on the identification of salmonid bones retrieved from Hofstaðir, the people living at the farm likely engaged in small-scale production of transportable fish products based on locally available wild resources.

The Storyteller: Concealment, Memory, And The Architecture Of Exile, Dylan Hirsh

Theses and Dissertations

The Storyteller is an expressive documentary investigating the life of Francis Kalnay (1899–1992). A Jewish-Hungarian intellectual, Kalnay lived as a socialist, an X-2 Counter-espionage chief for the American Office of Strategic Services (OSS) during World War II, an architect in Mexico, and a celebrated children's book author. The film's central conflict lies in his hidden identities and exploring how, despite his position as a high-level spy, he failed to save his sister and mother from death at the hands of the Nazi-aligned Arrow Cross government. As a filmmaker investigating a lost part of my own Jewish-Hungarian heritage, I believe Kalnay …

Together, their works illuminate militarization and surveillance technologies at the border and the violent enforcement of U.S. immigration policy.

Signs In The Landscape: Authenticity, Ambiguity, And The Work Of Richard Long, Heather Green-Gulez

Theses and Dissertations

This thesis examines Richard Long’s walking-based practice as a sustained and direct engagement with lived experience, tracing his development through walking landscapes, marking, and documentation. It negotiates tensions between reductive and hermeneutic readings, ultimately arguing that Long gestures toward pre-agrarian land ethics, raising broader questions of authenticity in modern life.

From Guyana To Queens: The Formation Of The Indo-Guyanese Ethnoburb In New York City, 1970-1990, Lianne R. Persaud

Theses and Dissertations

Expanding on Li’s concept of ethnoburbs, this study examines Indo-Guyanese settlement in Little Guyana, Queens (1970–1990). I propose the Vertical Enclave Model, which suggests that multi-family homeownership and internal rental markets facilitated the residential permanence of working-class individuals. The IPUMS Census microdata corroborates this community’s reliance on metropolitan integration, thereby refuting traditional self-sufficient ethnic enclave theories.

The Effect Of Drought On Avian Migratory Patterns And Stopover Through Texas And Louisiana, Ian Becker

Theses and Dissertations

Extreme weather events pose a massive threat for native ecosystems. As precipitation and temperature patterns are altered due to climate change, drought may become an incredibly severe event on the landscape. Drought directly impacts resources that migratory birds need during stopover en route to breeding and non-breeding grounds. Here, I quantify the impacts of drought on migration through Texas and Louisiana using 26 years of weather surveillance radar data. To understand how drought interacts with the local environment to impact migration, I tested 4 hypotheses displaying drought’s ability to impact migrants in conjunction with climatic and habitat level characteristics. Fall …

These Wretched Waters: A New Perspective On The Myth Texts And Visual Adaptations Of The Danaids, Tessa Haney

Theses and Dissertations

Both Greek and Latin texts regarding the Danaids are rife with gestational imagery and vocabulary. This textual focus on chthonic, symbolic aparturience coheres with both Greek and Roman perceptions of femininity. Women in both cultures were socially mandated to marry, have children, and confine themselves to the domestic sphere. The Danaids’ refusal to participate in this system would have been viewed as a breach of cosmic order, and a punishment that grounded the sisters in their 'traditional’ femaleness would have been viewed as a solution to such a breach. While early modern visual adaptations of the Danaid myth lack gestational …

Robust And Interpretable Cross-Domain Arabic Readability Prediction Using Hybrid Modeling: Evidence On The Limitations Of Transformer-Based Classifiers, Sarah Alzu'bi

Theses and Dissertations

Automatic readability assessment aims to predict how difficult a text is for readers to understand. The concept of readability has been widely studied across languages due to its significant impact on reading comprehension, leading to the development of various methods and approaches. In this study, I addressed two key challenges in readability assessment. First, I examine the performance of statistical classifiers and transformer-based models, including CAMeLBERT(Inoue et al, 2021.) with a focus on their ability to generalize under domain, genre, and stylistic shifts. Second, I investigate the interpretability of transformer performance in readability task, which are often criticized for their …

The Effectiveness Of Public-Private Partnerships In Addressing Residential Urban Development Challenges In Greater Cairo, Sara Nagy Abdelmessih

Theses and Dissertations

This research explores the effectiveness of Public-Private Partnerships (PPPs) in tackling the residential urban development challenges facing Cairo today. In the past two decades, PPPs have emerged as a dominant mode of housing production, positioned as collaborative ventures between state agencies and private developers. They have become integral to the expansion of Greater Cairo, producing vast new urban extensions under the promise of mobilizing private capital, technical expertise, and delivery capacity. Yet, questions remain about whether these arrangements genuinely address Egypt’s most urgent housing needs, or whether they reproduce market-driven logics that leave large segments of the population excluded.

The construction industry is one of the most polluting sectors worldwide and is considered one of the top greenhouse gas emitters. Egypt, in particular, is one of the most vulnerable countries to the adverse effects of climate change. The construction sector plays a major role in Egypt’s economy, contributing significantly to the national GDP, yet it also represents one of the country’s largest greenhouse gas emitters. However, the Egyptian Concrete Code does not enforce the …

Law And The (Re)Production Of Class Hierarchies In Egypt, Ahmad Abdelnaby

Theses and Dissertations

This thesis investigates how Egypt’s legal system, structurally tilted toward the elite and constitutive of inequality, has interacted with the country’s entrenched culture of class-based discrimination to produce a legal culture uniquely comfortable with hierarchy. It contends that class-based discrimination in Egypt has evolved from a social prejudice into a juridical condition, one in which the law does not merely mirror inequality but actively constructs and rationalizes it. By examining the intersection between legal structure and Egypt’s entrenched moral order of class-based discrimination, the study reveals a legal culture that no longer hides its hierarchies behind the veil of neutrality …

The study also tests the mediating roles of ascription of responsibility and attitude toward pro-environmental behavior on the examined relationship. Another aim of the study is to explore intention as a mediator in the relationship between attitude toward pro-environmental behavior and behavior. The research is based on the Norm Activation Theory (NAT) and the Theory of Planned Behavior (TPB). A mixed-methods approach was implemented in this study. Quantitatively, a survey was conducted, and 406 responses were collected using convenience sampling …

An Ethnographic Exploration Of The Lived Experiences With Gynecologic Cancers, Norma Naser Aldeen

Theses and Dissertations

Abstract

This thesis stays close to conversations with nine women who spoke about living with and through gynecologic cancers, from moments of finding out, through treatment, and into what follows. These encounters unfolded primarily through digitally mediated exchanges across Baalbek, Beirut, and other translocal settings shaped by distance and movement. Rather than approaching illness as a bounded biomedical event, this thesis attends to how gynecologic cancer is narrated as something that lingers—pressing into everyday life through bodily sensations, altered rhythms, and ongoing recalibrations of care, responsibility, and what remains possible.

Across these encounters, care rarely appears as a stable system …

A Study Of The Intellectual Property Rights Of Farmers With Special Reference To The Protection Of Plant Variety And The Farmers' Rights Act, 2001, Gomathi R Ms

Theses and Dissertations

Intellectual Property Rights (IPR) confer exclusive rights on individuals over the creations of their minds. Intellectual property is protected through patents, trademarks, copyrights, industrial designs, geographical indications, and other legal rights, enabling inventors to obtain economic benefits and legal recognition from their innovations. These rights provide exclusive usage for a prescribed period and have evolved significantly over the years, sharing similarities with ownership rights over tangible property. As intangible rights, IPR primarily consist of the property element and the object to which that property relates. Among the various forms of IPR, Plant Variety Protection (PVP) rights recognize the creativity and …
