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. …

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

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

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 …

Mechanical & Aerospace Engineering Faculty Publications

Heart failure remains a leading cause of global morbidity and mortality, yet routine clinical indices often miss the regional biomechanical disturbances that drive progression and shape treatment response. This State-of-the-Art review examines how finite-element (FE) modeling, additive manufacturing, and artificial intelligence (AI) are converging to improve the diagnosis, phenotyping, procedural planning, and prognostic assessment of heart failure (HF). Although these technologies have matured in structural heart disease and transcatheter intervention research, their greatest translational potential may lie in HF, where patient-specific ventricular remodeling, myocardial stress–strain heterogeneity, valve-ventricular coupling, and device-tissue interaction are incompletely captured by conventional clinical indices. We synthesize …

Debauchery And Decorative Art: Framing The Relationship Between Dining And Material Culture In British Country And Town House Dining Rooms During The Long 18th Century, Guoyang Sun

MA in Fine and Decorative Art and Design Dissertations

This dissertation explores the profound effect of material culture and rituals in elite British dining interiors during the long eighteenth-century. As spaces greatly influenced by the process of museumification, they are often perceived by contemporary and historical observers as settings intended for the ostentatious display of family lineage, taste and affluence. The dining rooms of British Georgian formal houses were highly curated proto museums with huge potential for display through architectural expressions, artworks and decorative objects, however, they were more importantly extremely complex environments that require complete analysis from multiple disciplines and perspectives.

In framing the intimate relationship between dining …

Making The Invisible Visible: How Contemporary Artists Depict The Climate Crisis Through Visual And Conceptual Strategies, Isabella Ray

MA in Contemporary Art Dissertations

This dissertation examines how contemporary artists depict the environmental consequences of climate change through visual and conceptual strategies. Through the examination of different artworks: Olafur Eliasson’s Ice Watch (2014-2018) and Your Waste of Time (2006), John Gerrard’s Western Flag (Spindletop, Texas) (2017), and Mary Mattingly’s Waterpod (2009) and Swale (2016-2020), this research analyzes how site, material choice, and civic participation create ecological awareness and model possible futures. Eliasson’s installations prompt phenomenological engagement with melting glacial ice and temporalities beyond human perception; Gerrard’s real-time simulations critique humanity’s dependence on fossil fuels through the digital presentation of a perpetual burning flag; Mattingly’s …

On Liminality: Rachel Whiteread & Archiving The In-Between, Natalie Emmerman

MA in Contemporary Art Dissertations

This dissertation examines the sculptural practice of Rachel Whiteread (b. 1963) through the lens of liminality, the uncanny, and the archive. By casting the negative spaces of everyday objects, domestic interiors, and monumental architecture, Whiteread materializes absence and transforms overlooked objects and spaces into solid, lasting forms. Her work destabilizes binary categories such as presence and absence, private and public, representation and abstraction, and permanence and ephemerality, exposing memory as fragile, discontinuous and often ghostly. Drawing on theoretical frameworks rooted in psychoanalysis, photography, time and space, this study explores Whiteread’s practice as a form of sculptural archivization.

Analysis is structured …

Objective Assessment In Experiential Learning Contexts, Lily M. Brutger

All Electronic Theses and Dissertations

Experiential learning is widely recognized as a powerful approach to education; however, empirical evidence demonstrating its effectiveness remains limited. This gap in the literature is due less to the value of experiential learning itself than to the challenges of assessing learning within experiential contexts. Drawing on the foundational experiential learning theories of Kolb (1984) and Joplin (1981), as well as contemporary research on assessment validity and practice, this paper examines the relationship between assessment and experiential learning. It argues that purposeful, objective assessment is essential for maximizing student learning and supporting the credibility of experiential education. The paper synthesizes current …

All Electronic Theses and Dissertations

This thesis reviews the use of primary sources in education. This literature review analyzes 30 articles regarding educators’ use of primary sources. There are four major themes within the articles: literacy with primary sources, engagement with primary sources, comprehension with primary sources, and examples of primary source units or lessons. While specific teaching topics vary, the overall consensus is that primary sources can help students’ skills with literacy, engagement, and comprehension. A main topic among the research is the educators’ understanding of scaffolding, pre-teaching, choosing primary sources, and re-using the primary sources, to be able to teach students effectively.

Meconium Metal Concentrations And Infant Temperament And Development, Fiona Fogarty

Dissertations and Theses

BACKGROUND: Prenatal exposure to metals poses significant health consequences for early childhood development. Understanding the factors influencing metal concentrations that infants are exposed to in-utero is crucial for developing targeted interventions, particularly when maternal characteristics and environmental factors, may contribute to varying levels. Meconium offers insight into in-utero exposures for the developing infant, and the effect of each individual metal may be mediated or exacerbated by another and therefore should be studied in the context of a mixture. The effect of metal mixture exposure, as measured in meconium, on milestone and temperament outcomes has yet to be determined.

An Engine, Not A Vessel: Place, Politics, And Health In The United States, Philip B. Rocco

Political Science Faculty Research and Publications

Social scientists often treat places as containers for social and economic phenomena that shape health outcomes. Yet this analytic practice conceals more than it reveals. Local governments in the United States should be understood as engines of both health promotion and stratification. As the contributions to this symposium suggest, governments not only occupy a formal place in the U.S. public health system, their decisions on everything from housing to transportation infrastructure can also have profound impacts on health outcomes. Local political economies likewise renegotiate the parameters of acceptable health interventions, public understandings of health disparities, and the status of population …

A Thymine Dimer Stalls A High-Fidelity Dna Polymerase By Providing No Template Information In The Same Manner As An Abasic Site, Amanda R. Walsh, Hye Rhee Kim, Lorena S. Beese, Eugene Y. Wu

Biology Faculty Publications

Cyclobutane pyrimidine dimers are photolesions that form when UV-B irradiation causes adjacent thymine or cytosine bases to covalently bond and can arrest DNA synthesis by replicative polymerases. To gain insight into the effects of cis-syn cyclobutane thymine dimers (T=T) on DNA replication in a model polymerase, we conducted solution and crystallographic studies of the Bacillus DNA polymerase I large fragment (BF) in complex with a T=T-containing template and an incoming dNTP. A thymine dimer lesion blocked nucleotide addition by BF in solution. The crystal structure of the BF-T=T-dATP complex indicated that the thymine dimer is too large to enter the …
