Between Commodity And Culture: Tea Advertising As A Site Of Imperial Ideology And Anti-Colonial Resistance In India, Sydney Pascal Jan 2026

Between Commodity And Culture: Tea Advertising As A Site Of Imperial Ideology And Anti-Colonial Resistance In India, Sydney Pascal

Honors Theses

Between the late nineteenth century and Indian independence in 1947, tea advertising became a key site through which imperial authority and Indian nationalism were negotiated. Drawing on advertisements, trade journals, and visual marketing campaigns produced from the 1880s through the 1950s, this honors thesis argues that tea advertising was a cultural and political mechanism through which the British Empire attempted to normalize imperial consumption and legitimize colonial authority. British campaigns framed tea as modern and routine while obscuring the exploitative labor systems and landscape transformations that sustained plantation production in Assam. As nationalist movements expanded in the early twentieth century, …

The Nfl’S Collision With Antitrust Law: A Strategy For Defending The National Football League’S Joint Agreements With Streaming Providers, Jack Mays Jan 2026

The Nfl’S Collision With Antitrust Law: A Strategy For Defending The National Football League’S Joint Agreements With Streaming Providers, Jack Mays

Chapman Law Review

The next frontier of sports broadcasting is here. Media consumption has shifted dramatically in recent years. Streaming services have become the preferred medium for television shows and movies, and sports broadcasts have expanded beyond traditional cable to streaming services. Given this reconfiguration of public behavior, the Sports Broadcasting Act (SBA)—a 1961 exemption to antitrust law—should be construed to allow the National Football League (NFL) to collectively negotiate with streaming providers like Amazon Prime Video, Peacock, and Netflix.

The SBA exempts joint agreements between professional sports leagues and broadcasters from antitrust scrutiny when those agreements involve the “sponsored telecasting” of games. …


Reactionary Radicals, Radical Reactionaries: A Review Of Against The Machine: On The Unmaking Of Humanity, Michael Kirby Jan 2026

Reactionary Radicals, Radical Reactionaries: A Review Of Against The Machine: On The Unmaking Of Humanity, Michael Kirby

Publications and Research

Paul Kingsnorth, in his book Against the Machine: On the Unmaking of Humanity, asserts that the ecological destruction, consumerism, and social atomization that have come to define contemporary life are the product of a malevolent force he calls the Machine. This review finds that his proposed solution to these crises, namely a return to "traditional" forms of family and community, insufficiently addresses the material and structural conditions underlying the capitalist mode of production. Kingsnorth’s dismissal of Marxism is then interrogated by juxtaposing his critique of the Machine with Marx’s analysis of estranged labor. Finally, this review concludes that the …

Gradient-Based, Post-Optimality Sensitivity Analysis With Respect To Parameters Of State Equations, Gene Hou, Jonathan Degroff Jan 2026

Gradient-Based, Post-Optimality Sensitivity Analysis With Respect To Parameters Of State Equations, Gene Hou, Jonathan Degroff

Mechanical & Aerospace Engineering Faculty Publications

Design optimization is a computational tool that can enable a designer to investigate the effectiveness of a design concept in an organized format. However, this design process requires the design variables, constraints, and objective function to be properly defined and expressed in mathematical forms. Post-optimality analysis thus becomes a necessary step to investigate different variations in the problem formulation and parameters to ensure that optimization produces a stable and trustworthy outcome. One efficient way to achieve this aim is to compute the local derivative of the optimized objective function with respect to the optimization problem parameters, such as bounds on …


Uncertainty-Aware Estimation, Planning, And Control For Tracking Multiple Drifting Patches In Flow Fields, Daniel O. Akanji, Krishnanand N. Kaipa, Cong Wei Jan 2026

Uncertainty-Aware Estimation, Planning, And Control For Tracking Multiple Drifting Patches In Flow Fields, Daniel O. Akanji, Krishnanand N. Kaipa, Cong Wei

Mechanical & Aerospace Engineering Faculty Publications

In this study, we present a replay-based framework for uncertainty-aware persistent tracking of multiple advected surface patches using an autonomous marine vehicle operating in spatiotemporal-varying currents. The method combines three components: local flow estimation, covariance-aware patch-boundary propagation with intermittent boundary fusion, and mission-level scheduling over multiple patches. Each patch is represented by a polygonal boundary, whose vertices are propagated through the estimated flow field while carrying per-vertex covariance, thereby quantifying uncertainty growth during advection. A flow-aware gain-scheduled linear quadratic regulator (LQR) was designed to shape the desired surge speed to take advantage of favorable currents. When the vehicle services a …


Influence Of Motion Artifacts On Instantaneous Frequency Based Heart Rate Variability Of Arterial Pulse Signals Measured By A Tactile Sensor: An Analytical Study, Mamun Hasan, Zhili Hao Jan 2026

Influence Of Motion Artifacts On Instantaneous Frequency Based Heart Rate Variability Of Arterial Pulse Signals Measured By A Tactile Sensor: An Analytical Study, Mamun Hasan, Zhili Hao

Mechanical & Aerospace Engineering Faculty Publications

Objective: Heart rate variability (HRV), quantified via the instantaneous frequency (IF) of arterial pulse signals, is a key indicator of cardiovascular (CV) regulation. This study presents a theoretical and experimental investigation of how motion artifacts (MA) influence IF-and thus HRVmeasured with a tactile sensor, emphasizing underlying mechanisms rather than population-level validation. Approach: Building on a previously developed single-degree-of-freedom (SDOF) model of the tissue-contact-sensor (TCS) stack between the sensor and the artery, MA is represented as low-frequency baseline drift and time-varying system parameters (TVSP) of the TCS stack. Analytical expressions quantify the effect of MA on the IF of each harmonic …

Ai-Supported Socratic Questioning And Instructional Scaffolding: Effects On Student Comprehension, Reshma John Jan 2026

Ai-Supported Socratic Questioning And Instructional Scaffolding: Effects On Student Comprehension, Reshma John

All Electronic Theses and Dissertations

This literature review examines how the intentional use of artificial intelligence (AI) designed for Socratic questioning and instructional scaffolding affects students' comprehension of course content. The literature suggests that AI is most likely to support comprehension when it prompts students to explain their reasoning, respond to guided questions, reflect on their understanding, and receive support adapted to their needs. In contrast, systems that primarily provide direct answers may encourage overreliance and mask gaps in students' understanding. Overall, the educational value of AI depends less on its availability and more on how it is designed and implemented.

This creative thesis aims to develop a practical crisis communication guidebook for small and medium-sized food businesses. Compared with larger businesses that have greater human and financial resources, small and medium-sized food businesses are often more vulnerable to the influences of crises on revenue and reputation. For this reason, they have a bigger need for practical and systematic crisis guidance. This project is grounded in crisis communication theory and analyzes existing literature in order to translate academic research and theoretical knowledge into an applied guidebook.

The guidebook is organized into three sections based on the timeline of crisis development: before …


Good Girl Bootcamp: Performative Femininity, Purity Culture, And Other Things Girls Are Taught, Kiersten Holland Jan 2026

Good Girl Bootcamp: Performative Femininity, Purity Culture, And Other Things Girls Are Taught, Kiersten Holland

Masters Theses

Performative femininity is a dangerous and controlling idea that subjugates women and places their inherent worth on how well they can conform to societal standards in male dominated spaces. Consequently, the reactionary messaging that surfaced as a result of these social pressures created a series of stereotypical female characterizations often depicted in the material and visual cultures of each period. By comparing contemporary literature with literature from the Victorian time period, it emphasizes the longstanding and controlling gender stereotypes pervasive throughout the past few centuries. This thesis attempts to understand and analyze the way that literature both critiques and supports …

Independence Of Spectral Contrast Effects Across Different Frequency Regions In Speech Perception, Christian E. Stilp, Matthew B. Winn Jan 2026

Independence Of Spectral Contrast Effects Across Different Frequency Regions In Speech Perception, Christian E. Stilp, Matthew B. Winn

Speech Pathology and Audiology Faculty Research and Publications

Identification of speech sounds is influenced by spectral contrast effects (SCEs), the perceptual magnification of spectral differences between successive sounds. SCEs result in the categorization of a target sound being biased away from spectral properties in the preceding acoustic context. Given remarkable consistency in the magnitudes of these contrast effects within the same frequency region, it was hypothesized that they would also show stable relationships across different frequency regions. In this study, normal-hearing listeners’ phoneme categorization and contrast effects were assessed where phonetic contrasts were driven by changes in low-frequency F1 (“big”-“beg” continuum), mid-frequency F3 (“dot”-“got”), or high-frequency …

Instructional approaches such as explicit vocabulary instruction, scaffolding, discourse-based strategies, reciprocal teaching, cognitive strategy instruction, …


Regulatory History And Judicial Review, Todd Phillips, Anthony L. Moffa Jan 2026

Regulatory History And Judicial Review, Todd Phillips, Anthony L. Moffa

Faculty Publications

The Administrative Procedure Act requires federal agencies to simply "incorporate in the rules adopted a concise general statement of their basis and purpose" after they receive comments from the public, and the Supreme Court ruled in Overton Park that courts are to adjudicate whether rules are arbitrary and capricious based on agencies' contemporaneous rationales. Judge-created doctrines incentivize agencies to rely on these "concise" statements to elucidate their rationales, and as a result, rulemaking preambles have ballooned in size as agencies seek to insulate themselves from critical courts.

This article contends that although the APA's statutory requirement is in tension with …


Suicide Stigma In A Cross-Cultural Context: Comparison Between Mexican And Mexican American Communities., Robin E. Gearing, Micki Washburn, Kathryne Brewer, Luis R. Torres-Hostos, Pedro Isnardo De La Cruz, Miao Yu, Natalia Giraldo-Santiago, Alberto Cabrera, Adelaido Garcia Andres Jan 2026

Suicide Stigma In A Cross-Cultural Context: Comparison Between Mexican And Mexican American Communities., Robin E. Gearing, Micki Washburn, Kathryne Brewer, Luis R. Torres-Hostos, Pedro Isnardo De La Cruz, Miao Yu, Natalia Giraldo-Santiago, Alberto Cabrera, Adelaido Garcia Andres

School of Social Work Faculty Publications

Suicide and suicide-related stigma are serious public health issues affecting Latine communities and often serve as a barrier to help-seeking Mexicans and Mexican Americans experiencing mental health concerns. Despite this, there are still gaps in our understanding of how suicide stigma specifically impacts Latines of Mexican heritage. While Mexicans and Mexican Americans share many familial, cultural, and religious values, their exposure to different societal norms may shape distinct perceptions of suicidal ideation and mental health. To better understand suicide-related stigma in these communities, we conducted a community-based survey with 248 Mexican Americans in Houston and 203 participants in Mexico City …


The Digital In The Library: Finding The Mutually Beneficial Synergy, James M. Donovan Jan 2026

The Digital In The Library: Finding The Mutually Beneficial Synergy, James M. Donovan

Law Faculty Books and Chapters

With the value of access to digital resources abundantly demonstrated during the COVID-19 lockdown, enthusiasm for the format is reaching new heights. This chapter counsels restraint, rebutting the argument that skepticism concerning the wide adoption of digital materials into the library is due merely to nostalgia by anti-technologists for a now-bygone age. Despite their obvious usefulness in certain situations, patrons have not responded well when libraries propose to discard legacy print collections in favor of transient electronic formats.To explain this rejection, this chapter argues that libraries are built upon principles of collection development and organization of materials in order to …

Systematic Approaches To Characterizing Vulnerabilities And Enhancing Robustness Of Text And Vision-Language Models, Poojitha Thota Jan 2026

Systematic Approaches To Characterizing Vulnerabilities And Enhancing Robustness Of Text And Vision-Language Models, Poojitha Thota

Computer Science and Engineering Dissertations

The proliferation of artificial intelligence (AI) across critical domains, including news summarization, privacy-policy analysis, and medical decision support, has raised growing concerns about the security and robustness of these systems against adversarial manipulation. This dissertation investigates adversarial robustness in generative AI by addressing three key research goals: (1) characterizing adversarial vulnerabilities across generative models, (2) developing systematic defenses to improve the robustness of generative models, and (3) designing deployment-time safeguards for securing LLM interactions.

Towards the first goal, we characterize adversarial vulnerabilities across text-based and multimodal systems. In abstractive text summarization, we show that inference-time perturbations can exploit lead bias …
