Gait Measurement Descriptions Of Human Tracks, Robert Speiden Nov 2024

Gait Measurement Descriptions Of Human Tracks, Robert Speiden

International Journal of Missing Persons

Search and rescue missions use a variety of tools to find missing persons, one of which can be visual tracking. Trackers detect, interpret and document information about human contact with the ground. Humans typically move on two feet at various speeds. Movement as an obligate biped leaves a series of footprints that alternates from one side to the other. This pattern of footfalls is rather simple, and the footfalls can be easily divided into descriptive dimensions.

This work summarized published measurements of bipedal gait ground contact points in 70 resources. Four resource types were surveyed including 33 biomechanical gait analysis …


Habitat Preferences Of The Hiwassee Crayfish (Cambarus Hiwasseensis) And Appalachian Brook Crayfish (Cambarus Bartonii Cavatus) In A Headwater Stream, Johnathan G. Davis Nov 2024

Habitat Preferences Of The Hiwassee Crayfish (Cambarus Hiwasseensis) And Appalachian Brook Crayfish (Cambarus Bartonii Cavatus) In A Headwater Stream, Johnathan G. Davis

Georgia Journal of Science

The Hiwassee crayfish Cambarus hiwasseensis (CH) is an endemic species to the Hiwassee River watershed in north Georgia and western North Carolina that is sympatric with the more widespread Appalachian Brook crayfish Cambarus bartonii cavatus (CB). This was the first study to investigate CH habitat use, comparing CH habitat to CB habitat in Corn Creek, a small, second-order stream in the Hiwassee River watershed. From August to November 2016 and January to April 2018, 15 habitat parameters were measured for 154 1-m2 quadrants randomly sampled from an 800-m stream reach. Mann-Whitney U tests compared habitat parameters between present and …

Visuality Of Race In Popular Culture: Teaching Racial Histories And Iconography In Media, Joni Boyd Acuff, Amelia M. Kraehe

Dialogue: The Interdisciplinary Journal of Popular Culture and Pedagogy

The repetition of racist imagery from historical to contemporary popular culture is indicative of a lack of visual culture education among artists, designers, and other creative cultural producers working today. This paper addresses the dearth of resources for teaching visual codes and conventions of racial iconography that are recycled in popular media and contribute to the fabrication of racial differences, maintenance of racial hierarchies, and normalization of white supremacist ideology. Inspired by Critical Race Theory in art and visual culture education, the essay proposes teaching tactics and sites/sights that can support students in developing visual understandings of race in popular …

The Tin Woodman, Captain Fyter, And Chopfyt: L. Frank Baum’S Portrayal Of Body Image And Prostheses In The Wake Of World War I, Marie Gethins

Dialogue: The Interdisciplinary Journal of Popular Culture and Pedagogy

Nineteenth and early twentieth-century children’s literature frequently depicts characters with disabilities as flat stereotypes — villains or saintly invalids. L. Frank Baum’s The Tin Woodman of Oz (1918) provides a sharp contrast to these typical portrayals, as well as contemporary “socio-cultural” beliefs on physical normalcy and sense of self. Written as the U.S. entered World War I and details of trench warfare reached the home-front, it presents an interesting exploration of society’s response to physical disability and prostheses. In addition, it highlights the psychological devastation associated with body changes.

During Baum’s formative years, disabled Civil War veterans returned to New …


The Seventh Amendment Right To Jury Trial In The Administrative State: Recognizing The Dangers Of The Constitutional Moment, Martin H. Redish, Samy Abdelsalam Nov 2024

The Seventh Amendment Right To Jury Trial In The Administrative State: Recognizing The Dangers Of The Constitutional Moment, Martin H. Redish, Samy Abdelsalam

Notre Dame Law Review

One prominent constitutional scholar has sought to legitimize this constitutional transformation through resort to a strange and controversial analytical model he describes as the “constitutional moment.” In this Article, we plan to establish two important points: (1) there exists no principled mode of analysis of the Seventh Amendment right to jury trial that justifies the Court’s categorical dichotomy between Article III and non–Article III forums for purposes of the right’s applicability, and (2) while the theory of the “constitutional moment” would in fact justify the Court’s insulation of the administrative state from Seventh Amendment applicability, reliance on such a theory …


Preemption: Opportunities And Obstacles For Climate Adaptation, Kevin J. Lynch Nov 2024

Preemption: Opportunities And Obstacles For Climate Adaptation, Kevin J. Lynch

Sturm College of Law: Faculty Scholarship

As high-level warming becomes more common, it is critical for human society to respond effectively and forcefully to meet the many challenges coming our way. We have to be prepared for a 1.5- to 4-degrees Celsius (°C) increase in temperature.1 The scale of the coming change and the relatively short time frame in which it will occur both suggest that our society will need to respond in a highly coordinated and efficient way to best put our limited resources to work. This in turn will require all levels of government - local, state, regional, national, and international - to work …

Statutory Religious Accommodation In Employment And The Problems Of Judicial Intent And Outcome, George Wright Nov 2024

Statutory Religious Accommodation In Employment And The Problems Of Judicial Intent And Outcome, George Wright

Texas A&M Law Review

The Groff v. DeJoy case unhappily, but inevitably, generates a variety of realistically unresolvable fundamental problems in typical statutory religious accommodation cases. Perhaps even more important, though, are the unintended and perverse results of Groff’s placing a generally heavier burden of religious accommodation on employers. The Groff standard indeed incentivizes the bringing of more religious discrimination cases, and both the winning and losing of such cases by religious claimants. But our adversarial cultural circumstances, including the typical inseparability of religion, politics, and culture, crucially affect the actual, but unintended, results of judicial reforms. The Groff rule is likely to …

Properties Of Relativistic Electron Precipitation: A Comparative Analysis Of Wave-Induced And Field Line Curvature Scattering Processes, Luisa Capannolo, Andrew Staff, Wen Li, Katharine Duderstadt, Nithin Sivadas, Joshua Pettit, Sadie Elliot, Murong Qin, Xiao-Chen Shen, Qianli Ma Nov 2024

Properties Of Relativistic Electron Precipitation: A Comparative Analysis Of Wave-Induced And Field Line Curvature Scattering Processes, Luisa Capannolo, Andrew Staff, Wen Li, Katharine Duderstadt, Nithin Sivadas, Joshua Pettit, Sadie Elliot, Murong Qin, Xiao-Chen Shen, Qianli Ma

Faculty Publications

We analyze the properties of relativistic (&gt700 keV) electron precipitation (REP) events measured by the low-Earth-orbit (LEO) POES/MetOp constellation of spacecraft from 2012 through 2023. Leveraging the different profiles of REP observed at LEO, we associate each event with its possible driver: waves or field line curvature scattering (FLCS). While waves typically precipitate electrons in a localized radial region within the outer radiation belt, FLCS drives energy-dependent precipitation at the edge of the belt. Wave-driven REP is detected at any MLT sector and L shell, with FLCS-driven REP occurring only over the nightside–a region where field line stretching is frequent. …

Telu Activation Function For Fast And Stable Deep Learning, Alfredo Fernandez Nov 2024

Telu Activation Function For Fast And Stable Deep Learning, Alfredo Fernandez

USF Tampa Graduate Theses and Dissertations

We propose the Hyperbolic Tangent Exponential Linear Unit (TeLU), a neural network hidden activation function defined as $TeLU(x)=x \cdot tanh(e^x)$. TeLU’s design is grounded in the core principles of key activation functions, achieving strong convergence by closely approximating the identity function in its active region while effectively mitigating the vanishing gradient problem in its saturating region. Its simple formulation enhances computational efficiency, leading to improvements in scalability and convergence speed. Unlike many modern activation functions, TeLU seamlessly combines the simplicity and effectiveness of ReLU with the smoothness and analytic properties essential for learning stability in deep neural networks. TeLU’s ability …


Exploring Llm Integration And Its Influence On Agent Behavior And Productivity In Insurance Call Centers, Gerardo L. Wibmer Gonzalez Nov 2024

Exploring Llm Integration And Its Influence On Agent Behavior And Productivity In Insurance Call Centers, Gerardo L. Wibmer Gonzalez

USF Tampa Graduate Theses and Dissertations

This study investigates the theoretical impacts of supportive AI tools, specifically Large Language Models (LLMs), on agent behavior and communication dynamics in call centers. While technological advancements have streamlined operations, limited research addresses the indirect ways these tools influence agent behavior. Using frameworks like context switching—the cognitive shift required when external stimuli prompt attention shifts—and the Hawthorne effect, where perceived observation modifies behavior, we examine how LLMs shape communication patterns. In call centers, this context switching occurs indirectly as agents adapt to AI note-taking features, whereas in industries like Architecture, Engineering, and Construction (AEC), automation tools prompt more immediate changes …

Genomic copy-number variations (CNVs) that can cause neurodevelopmental disorders often encompass many genes, which complicates our understanding of how individual genes within a CNV contribute to pathology. MECP2 duplication syndrome (MDS or MRXSL in OMIM; OMIM#300260) is one such CNV disorder caused by duplications spanning methyl CpG-binding protein 2 (MECP2) and other genes on Xq28. Using an antisense oligonucleotide (ASO) to normalize MECP2 dosage is sufficient to rescue abnormal neurological phenotypes in mouse models overexpressing MECP2 alone, implicating the importance of increased MECP2 dosage within CNVs of Xq28. However, because MDS CNVs span MECP2 and additional genes, we generated human …

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Hypertension is a multifactorial disease with stage-specific gene expression changes occurring in multiple organs over time. The temporal sequence and the extent of gene regulatory network changes occurring across organs during the development of hypertension remain unresolved. In this study, female spontaneously hypertensive (SHR) and normotensive Wistar Kyoto (WKY) rats were used to analyze expression patterns of 96 genes spanning inflammatory, metabolic, sympathetic, fibrotic, and renin-angiotensin (RAS) pathways in five organs, at five time points from the onset to established hypertension. We analyzed this multi-dimensional dataset containing ~15,000 data points and developed a data-driven dynamic network model that accounts for …


The Impact Of Hearing Aid User Speech On Environment Classification And Own Voice Listener Preferences, Robert Andrew Budinsky Iii Nov 2024

The Impact Of Hearing Aid User Speech On Environment Classification And Own Voice Listener Preferences, Robert Andrew Budinsky Iii

USF Tampa Graduate Theses and Dissertations

Hearing aids (HA) have improved over the past few decades with advanced signal processing, such as environment classification and background noise reduction, but are still limited by challenges related to when the user is speaking. These challenges include the potential interference a HA user’s voice has on device environment classification and the potential influence a HA has on own voice (OV) sound quality. However, the effects of OV on HA environment classification and signal processing are not well established, nor are the desired HA program settings regarding OV listening preferences. In this study, a combination of electroacoustic and behavioral methods …

Emergent Magnetism And Magneto-Transport Phenomena In Helimagnet-Based Heterostructures For Spin-Based Device Applications, Nivarthana Waruni Yapa Abeyrathna Yapa Mudiyanselage

USF Tampa Graduate Theses and Dissertations

The study of magnetoresistance (MR) phenomena in magnetic materials has been pivotal for advancing magnetic sensors and spintronic devices. Helimagnets, characterized by a non-collinear arrangement of magnetic moments that form a helical or spiral configuration, present an intriguing avenue for MR-based device applications. Theoretical predictions suggest that the MR magnitude in the helimagnetic (HM) regime can exceed that in the ferromagnetic (FM) regime by over an order of magnitude. However, in metallic helimagnets like manganese phosphide (MnP), the MR in the HM phase remains modest (< 10%), limiting its applicability in MR devices. This dissertation investigates the emergent magnetism and magneto-transport phenomena in nanostructured MnP helimagnets and their interfaces with ferromagnets (Fe) and ferrimagnets (Fe3O4), aiming to enhance device performance.

In the first part of the dissertation, we present a novel approach to achieve …
