An Occupational Perspective On Collegiate Athlete Mental Health, Katelyn D. Cardwell

Graduate Student Scholarship

College can impact mental health for all students, especially those involved in a college sport. Sports require significant time dedication that decreases time available for students to be involved in other activities such as academics or leisure which can lead to increased stress. This study focuses on investigating the impact level of competition and location of school may have on student athletes’ mental health in the state of West Virginia. A mixed methods self-report survey with a total of 75 questions was administered online via Qualtrics software. Quantitative data was analyzed using Stats IQ feature on Qualtrics and qualitative data …

High School Sport Participation: Effects On Students' Grit And Resilience, Rory Kekoa-Israel Waldman

Theses and Dissertations

Adolescence is a time of transition, growth, and identity exploration. Often this great time for growth is accompanied with an increase in stressors that can be detrimental to success and health, without the necessary coping mechanisms. It is a period of life where resilience and grit are extremely important. A post-traumatic growth definition for resilience allows for the possibility of a steeling effect, in which the resilience of an adolescent can grow and develop. Sport provides an ideal environment for the development of both grit and resilience by providing a safe environment for adversity to occur without detrimental consequences. In …

Collective Attribution In Cyberspace: A Rebranded Version Of Attribution Does Not Make It More Effective, Dan Efrony

International Law Studies

The international community has been unsuccessful in establishing an effective legal framework for holding States accountable for cyber wrongdoing. Instead, official political attribution—collectively denouncing States for irresponsible conduct in cyberspace—has become a common substitute to encourage compliance with voluntary non-binding international norms. Since December 2017, the United States and United Kingdom, along with their closest allies, have embraced and implemented collective attributions and responses. They thereby seek to shape “rules of the road” for responsible State behavior in cyberspace and to enhance accountability and deterrence. However, these attributions rely primarily on the outcomes of American and British attribution processes that …

Gaze Preferences To Male Contrapposto And Non-Contrapposto Postures, Farid Pazhoohi, Oliver Lee Jacobs, Alan Kingstone

School of Psychology

Contrapposto, an asymmetrical twisting of the hips and shoulders, has historically been associated with beauty and aesthetics in art. While the impact of a female contrapposto posture on perception of attractiveness and visual attention has been studied, its effects on males remain understudied. The current research aims to explore whether contrapposto postures in men influence perceptions of attractiveness, dominance, masculinity, dynamism, and naturalness, as well as visual attention. Two eye-tracking studies were conducted, utilizing images of male models in contrapposto and upright poses. Despite differences in attributions, no significant differences were found in visual attention between the two poses in …

Rational Design Of Lignin-First Biorefineries Through Lignin Analysis And Deconstruction Modeling Tools, Aditya Ponukumati

McKelvey School of Engineering Graduate Student Theses & Dissertations

Lignocellulosic biomass is produced photosynthetically from atmospheric CO2 and is one of the few sources of renewable, reduced carbon that is generated on a scale comparable to demand for chemical commodities. For a sense of scale, the U.S. Energy Security and Independence Act targets the production of approximately 16 billion gallons per year of second-generation lignocellulosic biofuels by 2025. That production would generate approximately 62 million tons per year of dry lignin byproducts. The focus of this dissertation is on the valorization of these lignin components of biomass. Currently, lignin is either discarded or burned for local heat or electricity …

Computational Modelling And Design Of Antibodies: Benefits From Analysis Of Their Unique Structural Motifs, Katherine M. Mccoy

Dartmouth College Ph.D Dissertations

The complexes that antibodies make with their binding partners, or antigens, are especially valuable to be able to predict and modify due to their unique role in the immune system. Yet, they present significant challenges to computational methods of both modelling and design. Antibodies are unlike most other proteins in that they are composed of a scaffold region, which is a highly conserved structure that is largely the same between antibodies of the same class, and Complementary Determining Regions (CDRs), which are comprised of hypervariable loops that largely determine their binding motifs. Additionally, antibodies and their antigens do not co-evolve …

Sociocultural Effects On Suicidal Ideation Among South Asian Immigrants, Rezwana Ahmed Choudhury

Walden Dissertations and Doctoral Studies

With the growing South Asian immigrant population in the West, it is necessary to conduct suicide-related studies among this population to understand the reasons behind suicidal ideation faced by this population. This quantitative cross-sectional survey design study aimed to examine sociocultural factors that may be associated to the risk level of suicidal ideation among South Asian immigrants in the United States. A survey questionnaire was developed using a combination of demographic questions and existing instruments: the Suicide Ideation Attributes Scale, Religious Belief Salience Scale, Suinn-Lew Asian Self-Identity Acculturation Scale, and Rapid Eating Assessment for Participants—S. Data were collected from a …

The purpose of this qualitative study was to investigate how elementary teachers implement differentiated instructional strategies to support students of low socioeconomic status. The conceptual framework was based on Jerome Bruner’s constructivist theory, the growth of mind, because symbolic representation helps students visualize the world and enhance experiences. The research questions investigate how teachers implement differentiated instructional strategies to support students of low socioeconomic status and how they believe training on differentiated instructional strategies to support students …

Librarians Need Accomplices!, Robin Naughton Ph.D, Simone L. Yearwood

Publications and Research

The term “ally,” used to categorize a group of people from a dominant or majority group working to support marginalize people in the fight for justice is very active and well-known. Allies support without getting too involved or experiencing any trouble with their own life or profession. However, allies are not enough to fight for justice. People need to have accomplices, someone who will fight with them while the fight is happening, not stand idly by while injustices are being committed, and be an active partner and conspirator in the fight against racism, microaggressions, and injustice even if it means …

Detection And Mitigation Of Misleading Pheromone Trails In Foraging Robot Swarms, Ryan Luna, Qi Lu

Computer Science Faculty Publications

This study addresses the overlooked aspect of security in swarm robotics by exploring the vulnerabilities of stigmergic communication in foraging robot swarms. More specifically, we study the swarm's susceptibility to attacks that introduce misleading pheromone trails. Simulated scenarios in which detractor robots lay misleading trails to deceive benign foraging robots effectively reduce the foraging performance of the swarm. We analyze the impact of the attack on the swarm and evaluate the reduction of foraging efficiency. We introduce a defense mechanism using distance-based clustering (DBSCAN) along with a cluster grouping method to isolate large batches of detractors early in the simulation. …

Tuning Pid Controller For Quadrotor Using Particle Swarm Optimization, Eric X. Rodriguez, Qi Lu

Computer Science Faculty Publications

Energy expenditure for quadrotor control has a likelihood of being costly given parameter-dependent controllers that are less than optimal. The cost can grow proportionally when applied to multiple quadrotors for tracking and collaborative navigation tasks. This research aims to establish a basic approach to tuning PID (Proportional-Integral-Derivative) parameters for a simulated quadrotor drone. A PID controller for autonomy provides a straightforward method for correcting robotic movement based on its current state. However, applying a PID system to a flight controller poses challenges with an inherently under-actuated system, which includes the likelihood of large overshoots and lengthy adjustment times. To address …

Faculty, Staff and Student Publications

Alzheimer's disease (AD), a leading cause of dementia, is associated with significant respiratory dysfunctions. Our study explores the role of astrogliosis in the brainstem retrotrapezoid nucleus (RTN), a key breathing regulatory center, and its impact on breathing control and AD pathology in mice. Using Tg-2576 AD and wild-type mice, we investigated the effect of silencing the transforming growth factor-beta receptor II (TGFβR II) in the RTN. We performed behavioral tests, including the Barnes maze and novel object recognition test, along with whole-body plethysmography to assess breathing disorders. Our results showed that AD mice exhibited increased apneas and cognitive impairment, which …

Mars' water history is fundamental to understanding Earth-like planet evolution. Water escapes to space as atoms, and hydrogen atoms escape faster than deuterium giving an increase in the residual D/H ratio. The present ratio reflects the total water Mars has lost. Observations with the Mars Atmosphere and Volatile Evolution (MAVEN) and Hubble Space Telescope (HST) spacecraft provide atomic densities and escape rates for H and D. Large increases near perihelion observed each martian year are consistent with a strong upwelling of water vapor. Short-term changes require processes in addition to thermal escape, likely from atmospheric dynamics and superthermal atoms. Including …

Glitch Veto Based On Unphysical Gravitational Wave Binary Inspiral Templates, Raghav Girgaonkar, Soumya D. Mohanty

Physics & Astronomy Faculty Publications

Transient signals arising from instrumental or environmental factors, commonly referred to as glitches, constitute the predominant background of false alarms in gravitational wave searches with ground-based detectors. Therefore, effective data analysis methods for vetoing glitch-induced false alarms are crucial to enhancing the sensitivity of a search. We present a veto method for glitches that impact matched filtering-based searches for binary inspiral signals. The veto uses unphysical sectors in the space of chirp time parameters as well as an unphysical extension including negative chirp times to efficiently segregate glitches from gravitational wave signals in data from a single detector. Inhabited predominantly …

A Friendship Of Two Prima Donnas: The Letters Of Adelina Patti To Giulia Valda, Jacquelyn Ancelet

LSU Master's Theses

Of the many prima donnas of the nineteenth century, Adelina Patti (1843–1919) stands out as one of the most successful, with a fifty-year international concertizing career. Biographers across multiple languages have covered her career in great depth, but devote little attention to her close friendships. Herman Klein (in The Reign of Patti [1920]) and John Cone (in Adelina Patti: Queen of Hearts [1993]), for instance, claim that Patti was known by many, but understood by few. One who does seem to have understood her and developed a close relationship with her was Giulia Valda (1850–1925), herself a professional singer, if …

Macrophage Depletion Protects Against Cisplatin-Induced Ototoxicity And Nephrotoxicity, Cathy Yea Won Sung, Naoki Hayase, Peter S T Yuen, John Lee, Katharine Fernandez, Xuzhen Hu, Hui Cheng, Robert A Star, Mark E Warchol, Lisa L Cunningham

2020-Current year OA Pubs

Cisplatin is a widely used anticancer drug with notable side effects including ototoxicity and nephrotoxicity. Macrophages, the major resident immune cells in the cochlea and kidney, are important drivers of both inflammatory and tissue repair responses. To investigate the roles of macrophages in cisplatin-induced toxicities, we used PLX3397, a U.S. Food and Drug Administration-approved inhibitor of the colony-stimulating factor 1 receptor, to eliminate tissue-resident macrophages. Mice treated with cisplatin alone had considerable hearing loss (ototoxicity) and kidney injury (nephrotoxicity). Macrophage ablation resulted in significantly reduced hearing loss and had greater outer hair cell survival. Macrophage ablation also protected against cisplatin-induced …

Porokeratosis Ptychotropica With Scalp Involvement: A Case Report, Kobpat Phadungsaksawasdi, Pravit Asawanonda

Chulalongkorn Medical Journal

Porokeratosis, a spectrum of disorders characterized by abnormal keratinization, includes the rare variant, porokeratosis ptychotropica, typically manifests with hyperkeratotic plaques on the buttocks and genital area. Its clinical mimicry to various skin diseases, coupled with under-recognition of the disorder, results in frequent misdiagnosis. This challenge is compounded by the resistance of porokeratosis ptychotropica to treatment.

We report a 62-year-old Thai male with persistent pruritic hypertrophic plaques affecting the genitogluteal area, extremities, and scalp over five years, unresponsive to diverse topical agents. Histopathological findings revealed acanthotic epidermis with a cornoid lamella, consistent with porokeratosis ptychotropica. He was given oral acitretin at …

Integrate To Win From Competition Through Conflict: Create A Joint Force Information Warfare Component Commander, Tam N. Pham, Walter A. Berbrick

Joint Force Quarterly

Τhroughout the history of warfare, militaries have sought advantages by conducting information warfare (IW) to affect the perception and behavior of adversaries. Advances in IW capabilities are increasing the reach, speed, and effectiveness by which individuals, organizations, and systems can collect, process, disseminate, or act on information—and deny adversaries the same. The United States is not the only power to recognize the importance of IW in achieving national objectives. Russia and China have made great strides in improving and employing their IW capabilities to offset U.S. joint (and allied combined) forces in competition and conflict. Russia’s and China’s ability to …

Winning In The Competition Continuum With Engineer Civic Assistance Projects, James M. Ward

Joint Force Quarterly

With a credible threat gap between the United States and competitor states shrinking, strategic dialogues increasingly emphasize competition to gain relative superiority prior to armed conflict.1 To frame the term competition, Joint Doctrine Note (JDN) 1-19, Competition Continuum, states, “Rather than a world either at peace or at war, the competition continuum describes a world of enduring competition conducted through a mixture of cooperation, competition below armed conflict, and armed conflict.”2 The JDN 1-19 perspective suggests that a state’s policies and objectives vary by its temporal position in the competition continuum.

Cognitive Warfare: The Fight For Gray Matter In The Digital Gray Zone, Michael J. Cheatham, Angelique M. Geyer, Priscella A. Nohle, Jonathan E. Vazquez

Joint Force Quarterly

Τhe United States is facing unprecedented challenges in the cognitive domain. While democracies struggle to develop frameworks that promote collective understanding, adversaries are employing gray zone tactics—those that never rise to the level of war—as a form of cognitive warfare against the United States and other democratic societies. François du Cluzel, head of innovative projects at the North Atlantic Treaty Organization (NATO)’s Allied Command Transformation Innovation Hub, describes the key distinctions of the emerging cognitive domain:

Cognitive warfare degrades the capacity to know, produce, or thwart knowledge. Cognitive sciences cover all the sciences that concern knowledge and its processes (psychology, …

Engines Of Chaos: Counterlogistics In Competition, 2023-A Class Of The Advanced Logistics Readiness Officer Course

Joint Force Quarterly

U.S. success at the operational level of war has led to a blossoming of competition in domains below the level of open hostility. The 2023 Joint Concept for Competing (JCC) points out that our adversaries seek to “win without fighting” and that the joint force is at risk of “losing without fighting.”2 The JCC attempts to reorient the joint force to better compete below the level of high-intensity conflict.

Was 50 Years Long Enough? The All-Volunteer Force In An Era Of Large-Scale Combat Operations, Kent W. Park, John A. Nagl

Joint Force Quarterly

Ιn an era of geopolitical competition among major powers, a large-scale war could last longer and result in more casualties than anything the United States has experienced since World War II. It is unclear whether the all-volunteer force (AVF) that the United States has relied on for the past 50 years, with extraordinary and unexpected success, can meet the manpower requirements in quality and quantity and in time to win the large-scale combat operations that the Department of Defense (DOD) is preparing for.
