Relationship Between Muscle Activation And Kinematic Features During Baseball Pitching, Maxwell Skene

Theses

Background: Baseball pitching is a biomechanically complex, high-velocity movement that places substantial demands on the upper extremity. Inefficient coordination between muscle activation and kinematic sequencing has been associated with reduced performance and increased injury risk, particularly at the shoulder and elbow. However, the integrated relationship between muscle activation patterns and three-dimensional kinematic features during pitching is not well-documented. Purpose: The purpose of this study was to examine the relationship between throwing-arm muscle activation patterns and three-dimensional kinematic characteristics during fastball pitching, with particular emphasis on segmental accelerations, proximal–distal sequencing, and the directional structure of movement quantified using Relative Dimensional Contribution …

Estoppel Without Regard To Equity? The Puzzling Omission Of Promissory Estoppel’S Inequity Condition In Canada, Marcus Moore

All Faculty Publications

Promissory estoppel plays an important role in enabling the enforcement of promises not made for consideration in cases where the promise was intended to and did induce a party to change its position in regard to preexisting legal rights. However, Canadian law on estoppel has been plagued by confusion and misunderstanding. This article addresses the internationally notable absence of an inequity requirement from promissory estoppel in Canada. The requirement’s absence is peculiar, in that estoppel’s very foundation is in equity, and it must assure that its effect is indeed equitable. Drawing on the Supreme Court of Canada’s decision in Trial …

Attitudes And Perception Of Lis Students Towards Artificial Intelligence(Ai), Shahzadi Humbhi, Shabbir Tareen, Alia Humbhi

Cotton Town Blues: An Investigation Of Social Inequality, Diet, And Health In A 19th Century Industrializing Population—St Peter’S Churchyard, Blackburn, Lancashire, Andy Barlow, Catriona Pickard, Linda Fibiger, Kerry L. Sayle, Sarah Schaeffer, Emma Smith, Julie Franklin, Brooke Carter, Lea Perrino, Clive Bonsall

Human Biology Open Access Pre-Prints

Historical accounts document that the shift from rural settlement to urban settings and from employment in cottage industries to factory working at the turn of the 19th century had a negative impact on the lower classes.

In 2015, the relocation of the cemetery of St Peter’s Churchyard in Blackburn, Lancashire, provided an opportunity to study the effects of industrialization on the diets and health of an early to mid-19th-century population through osteological and biomolecular analyses. Those interred at St Peter’s represent a socioeconomic cross-section of the church’s parishioners. In this paper, we present an evaluation of the lifetime dietary biographies …

Hybrid Machine And Deep Learning Framework For Secure Fog-Based Vanets, Hadeer Kamal, Amira Y. Haikal, Mahmoud M. Saafan

Mansoura Engineering Journal

As a conventional implementation of intelligent transportation systems (ITS), a Vehicular Ad-hoc Network (VANET) facilitates smart communication between vehicle nodes and network infrastructures. Nevertheless, the distributed and dynamic characteristics of VANETs make them vulnerable to numerous cyberattacks like DOS and spoofing. Rapid detection of these threats is crucial. It is essential to respond promptly to mitigate threats before they impact vehicle coordination or infrastructure functionality. In this context, fog computing presents an effective solution. Transferring computational tasks from centralized cloud servers to fog nodes allows for quicker detection within the VANET environment. This research utilizes computational resources for swift and …

College Athlete Mental Health: Identifying Sources Of Support In Collegiate Athletics, Levone Lee, Lauren Beasley, Kaylee A. Palomino, Patricia M. Kelshaw, Joycelyn Kennedy, Deborah Chanan, Elinah Russell, Tarkington J. Newman

Journal of Issues in Intercollegiate Athletics

Despite having access to resources and services, college athletes continue to encounter negative mental health experiences and outcomes. Prior research has begun to identify key sources of social support within collegiate athletics, including teammates and athletic trainers. However, there is limited understanding of with whom college athletes feel most comfortable discussing their mental health. The current study aims to identify preferred sources of social support when athletes wish to discuss their mental health and, in turn, examine differences in preference among unique college athlete populations. In total, 247 college athletes participated in the study, representing eight universities within an NCAA …

Esperanto: A Universal Or Minority Language, Anna Summerville

Student Scholar Symposium

When created languages develop a community and culture, they begin to imitate the elements of natural languages. Esperanto, a language created to unite the world under one lingua franca, demonstrates this process as it shifts from its original intention to a minority language in characteristic. “Esperanto: A Universal or Minority Language” explores the dichotomy between a language created to be spoken by all, and one that has isolated itself within its own community and customs. In discussing the history of Esperanto’s creation and structure, its evolving and loyal community, and its parallels with natural minority languages like Maori, this essay …

Human Moderators Behind The Ai: Unseen Costs And Hidden Consequences, Jacy Stricker

Student Scholar Symposium

This presentation is about AI-driven content moderation and the ethical and legal concerns surrounding the human moderators who oversee it. While AI helps filter content on platforms like TikTok and Instagram, it often fails to catch nuanced violations, exposing human moderators to harmful material with serious mental health consequences.

Complex Numbers And Phone Signals, Ava Barrett, Rebecca Brazeal, Javier Gutierrez

Student Scholar Symposium

Though widely used, complex numbers are often introduced in coursework without real-world context. Our team examines their application in electromagnetic waves and communication systems, focusing on how they help model and analyze phone signals. By connecting concepts from physics and math, we demonstrate their role in signal modulation and transmission. Through this project, we aim to highlight the practical importance of complex numbers in modern technology and provide a clearer understanding of their use in communication systems that power everyday devices like smartphones.

Our project focuses on the Czech immigrant community of St. John Nepomuk Church in St. Louis, one of the oldest historically Czech parishes in the United States. To promote awareness of the church’s cultural and historical significance, we are creating a dedicated website, informational pamphlet, and social media presence that highlight its history, architecture, and ongoing role in the community. We are also producing a video tour led by a prominent church member to introduce the site, alongside a testimonial video that preserves a personal perspective on the church’s legacy. Through these efforts, we aim to support cultural preservation and …

Habitat Disturbance And Biodiversity In Glade Habitats, Maddie Smith, Becky Hansis-O'Neill, Aimee Dunlap Phd

Undergraduate Research Symposium

The Ozark glades are home to a variety of reptiles, amphibians, rodents, and invertebrates such as tarantulas and scorpions. Glade inhabitants face challenges like habitat fragmentation and degradation, but they could be facing even bigger challenges as outdoor recreation becomes more popular. People looking for wildlife to photograph or collect often look under rocks without leaving them how they were found. This study focused on monitoring rock disturbance at two protected glades- Shaw Nature Preserve and a more accessible undisclosed glade in Jefferson County. Disturbing the glade habitat to look for wildlife is prohibited at both sites. Twenty rocks at …

Face Value: A Computational Approach To Subjective Impressions Of Faces, Kevin Kpankou

Undergraduate Research Symposium

Various computational models of first impressions have been developed to uncover the mechanisms driving these judgments. However, the implicit notion of a singular ``human'' often overlooks meaningful individual differences in beliefs, attitudes, and associations, as well as culturally grounded group-level constructs. In this paper, we extend Cultural Consensus Theory (CCT) to estimate culturally shared beliefs about faces by incorporating latent constructs structured around interpretable facial features extracted via computer vision algorithms. We apply our model to a large-scale dataset of people’s first impressions of faces. Our approach reveals a robust mapping between facial features and culturally constructed impressions, allowing us …

Influencing The Meteoric Rise Of Ai: Centering Ethics, Law, And Society In Urgent Policy Reform, Erin L. Shah Mspm, Heath A. Clark Mba, Xarlene B. Choi Bs, Garrett K. Chan Phd

The Guardianship Journal

Artificial intelligence (AI) represents a transformative technological advancement with the potential to yield extraordinary societal benefits while simultaneously introducing significant potential harms to individuals, governments, and society. The adoption of AI has outpaced the ability of society to collectively and cohesively respond through the implementation of adequate regulatory guardrails. While AI presents novel benefits and challenges, the broader dynamic of responding to new, uncharted technologies has historical precedence. The article's methodological approach employed empirical research using law articles and policies. As such, the article explores the benefits, challenges, and actual or potential harms in three business sectors: business and finance, …

Engaging Seminars: The Impact Of Storytelling In Public Safety Education, Mimi Gough, Glenn L. Walton

The Guardianship Journal

This paper examines the important role of storytelling in higher education as a technique for engaging students in course content and applies its relationship to the experiential learning theory (ELT) in which learners are actively seeking knowledge through authentic application. Storytelling can be a particularly effective method when used during live online seminars in public safety education, since this particular program of study often relies on verbally communicating realistic and credible information. Sharing various examples of actual encounters can help students better prepare for these types of situations when they face them in their future careers. Incorporating evidence to support …

Nature Naturing In And As Place, Edward S. Casey

Duquesne Studies in Phenomenology

In this brief article, I single out two distinctly different kinds of natural place, attempting to show how these not merely contrast with each other but display larger patterns or tendencies that are also found in many other sorts of place. This is to take one integral step to a larger ecology of places provided by the natural world and from which human and nonhuman beings draw life and motion that sustain and support many ways of existing on earth. Without such places, we—and every other form of life—would perish or would not even exist to begin with. It is …

Emotions As Work Material: On Dancers' Refined Use Of Affectivity, Camille S. Buttingsrud

Duquesne Studies in Phenomenology

As part of their professional practice, dancers allow their affectivity to enhance their kinesthetic work. Their intentional and disciplined use of personal, emotional resources ensures both creativity, interpretation, absorption, and connections in ways that extend beyond the traditional phenomenological understanding of affectivity as pre-reflectively based. The affective regulations dancers employ can be seen as an “artistic epoché,” and their layered performance awareness corresponds with Edmund Husserl’s descriptions of “image-consciousness.” Through qualitative interviews with three professional dancers, phenomenological theory, and additional supportive literature, this article shows how affectivity can be experienced through high-order levels of Leib, constituting states of “bodily …

Atmospheres Create Interest: Experiencing And Utilizing Shared Situations, Andreas Rauh

Duquesne Studies in Phenomenology

Even though atmospheres are usually only subtly perceived in the manner of a felt body in everyday life, they possess a specific efficacy. They hold the potential to address people in their felt-bodily constitution and to arouse interest in the shared situation. In the following, the phenomenon of atmosphere is explored through case analyses from an art education project and defined as a shared situation in contrast to affect and mood. This is followed by an examination of the fundamental importance of atmosphere for learning environments. With a focus on pedagogical relationships, the role of atmospheres in educational contexts and …

Artworks As Affective Atmospheres: Dufrenne's View Of Their Aesthetic And Philosophical Significance, Dimitris Apostolopoulos

Duquesne Studies in Phenomenology

This article reconstructs and critically evaluates Mikel Dufrenne’s arguments for the claim that our embodied engagement with art is the most fundamental variety of affective experience. I show how, on his account, aesthetic affectivity, or feeling, emerges in aesthetic experience, and identify the central role that aesthetic atmosphere plays in its constitution. I propose an interpretation on which aesthetic feeling, for Dufrenne, is a founded and skilled form of intentional activity that has epistemic (evidence-responsive) and metaphysical (world-disclosive) import. An aesthetic atmosphere, I contend, is an affective and perceptual context that is tied to an artwork and exercises a regulative …

With Images In Time. Atmosphere And Art: Mediation And Dialogue, Pauline Von Bonsdorff

Duquesne Studies in Phenomenology

The article challenges the idea that atmospheres are always sensed immediately. Instead, atmospheres in art are mediated and arise in a dialogue between work and audience. To understand how, we should pay attention to temporal structures in and around the work, such as the dynamics and duration of aesthetic experience and the historicity of both work and perceiver, including pasts and present. Mikel Dufrenne’s phenomenological aesthetics, complemented with insights from Maurice Merleau-Ponty’s analyses of perception, offer resources for this. Writing on expression, Dufrenne distinguishes “presence,” in which sense is felt immediately and firmly connected to embodiment, and “sentiment,” which arises …

Rapture "At A Distance": Searching For Pathic-Atmospheric Aesthetics, Tonino Griffero

Duquesne Studies in Phenomenology

The paper proposes a rethinking of the role of aesthetics as a theory of sensory experience as it is encountered in the lifeworld (and only secondarily in relation to art). Accordingly, pathic and atmospheric (bottom-up) aesthetics, which centers on the ability to expose oneself to intense experiences without attempting to control them and conceives feelings as atmospheric powers that permeate a particular space without being reduced to projections of the perceiver’s moods, should replace the idealistic (top-down) approach.

Ted Cruz, Tucker Carlson, And The 'Terrorists' Of January 6th: Mortification, Groveling, And Political Image Repair Discourse, Matthew Gerber, Kayla Rhidenour

Speaker & Gavel

This article examines the image repair discourse of Senator Ted Cruz (R-TX) as it relates to an incident that occurred on the Tucker Carlson Tonight show following the events of January 6th, 2021, at the U.S. Capitol. After referring to the January 6th rioters as “terrorists”, which angered his Republican base, Cruz was compelled to appear on Carlson’s highly watched Fox News program in an attempt to bolster his reputation. The authors argue that Cruz’s strategic approach is best classified as mortification, but also note and investigate the nonverbal, tonal, and extra-message influence of groveling as it played out in …

Surrogate Apologia: Posthumous Image Repair For Mac Miller, Chris Cornell, And Naomi Judd, Kevin Stein, Nicolas Stein, Matthew Barton

Speaker & Gavel

The essay examines the surrogate image repair/apologia offered by the family and friends of deceased musicians Mac Miller, Chris Cornell, and Naomi Judd following their untimely deaths from drug overdose or suicide. Typical image repair cases involve harmful behaviors, such as infidelity, violence, and racism, along with offenders required to speak on their own behalf in order to fend off threats to reputation. In the three cases explored in this analysis, the image threats emerged posthumously as surrogates spoke in defense of the legacies of these great musical artists. In order to fend off attacks from music fans, internet trolls, …

Change Gone Come?: Anti-Blackness And The Exclusion Of Black Judges In Mutual Preference Judging, Shanara Reid-Brinkley

Speaker & Gavel

The Mutual Preference Judging (MPJ) system has faced persistent criticism from coaches and debaters of color who note that MPJ has allowed traditional, plan-based (majority white and non-black) debaters to exclude the vast majority of Black judges from being placed in their debates. This article reviews the placement of Black judges in elimination rounds at national policy debate tournaments from 2013 to 2022. The review supports the argument that plan-based debate teams exclude Black judges from their judge preference sheets, significantly limiting Black representation in the elimination rounds of national tournaments.
