Wearable Sensor Gait Analysis For Fall Detection Using Deep Learning Methods, Haben Girmay Yhdego

Electrical & Computer Engineering Theses & Dissertations

World Health Organization (WHO) data show that around 684,000 people die from falls yearly, making it the second-highest mortality rate after traffic accidents [1]. Early detection of falls, followed by pneumatic protection, is one of the most effective means of ensuring the safety of the elderly. In light of the recent widespread adoption of wearable sensors, it has become increasingly critical that fall detection models are developed that can effectively process large and sequential sensor signal data. Several researchers have recently developed fall detection algorithms based on wearable sensor data. However, real-time fall detection remains challenging because of the wide …

Human Psychology Factors Influencing Agile Team Autonomy In Post-Pandemic Remote Software Organizations, Ravikiran Kalluri

Engineering Management & Systems Engineering Theses & Dissertations

Agile project management methods are gaining in popularity in the software industry as software development teams are being asked to be adaptive to market needs and resilient to change and uncertainty. With increasing market uncertainty, global competition, and time-to-market pressure, it is becoming a challenge to develop an innovative product and deliver it on-time without the opportunity that comes from team autonomy to experiment and learn from failures in a remote workplace. To resolve this challenge, it is critical to understand the myriad human psychological factors in play that influence Agile team autonomy in a remote work environment.

Promoting Skills In Children And Teens With Autism Spectrum Disorder Through Play And Steam, Meaghan Mcleod Mozingo, Krzysztof J. Rechowicz

Modeling, Simulation and Visualization Student Capstone Conference

Individuals with autism spectrum disorder (ASD) have a low employment rate. This is caused by a lack of support from employment resources and the negative stigma associated with common characteristics associated with ASD. With limited career-building activities and events, it is difficult for individuals with ASD to identify their skills, strengths, and career opportunities. Parental support is crucial when seeking employment opportunities for their children. Through the use of play, children with ASD engaged and explored their skills with science, technology, engineering, arts, and math-centered activities. This paper highlights the events and shows the proposed redesign for an additional workshop.

Hampton Roads' Building Resilient Communities Flood Game, Gul Ayaz, Katherine Smith, Rafael Diaz, Joshua G. Behr

Modeling, Simulation and Visualization Student Capstone Conference

As rising sea levels and subsequent recurrent flooding disproportionately affects coastal areas, it is crucial to develop a heightened awareness of the impacts of natural disasters on communities and the environments they live in. The Hampton Roads’ Building Resilient Communities (BRC) Flood Game is a simulation role-playing game designed to allow players to increase their understanding of the impact of various community response interventions to sea level rise and recurrent flooding. Players will examine and assess the tradeoffs of resiliency investments, the impact policies may have on the population, and the amount of time return on investment takes. The BRC …

Behind Derogatory Migrants' Terms For Venezuelan Migrants: Xenophobia And Sexism Identification With Twitter Data And Nlp, Joseph Martínez, Melissa Miller-Felton, Jose Padilla, Erika Frydenlund

Modeling, Simulation and Visualization Student Capstone Conference

The sudden arrival of many migrants can present new challenges for host communities and create negative attitudes that reflect that tension. In the case of Colombia, with the influx of over 2.5 million Venezuelan migrants, such tensions arose. Our research objective is to investigate how those sentiments arise in social media. We focused on monitoring derogatory terms for Venezuelans, specifically veneco and veneca. Using a dataset of 5.7 million tweets from Colombian users between 2015 and 2021, we determined the proportion of tweets containing those terms. We observed a high prevalence of xenophobic and defamatory language correlated with the …

A Comparison Of Nonverbal And Paraverbal Behaviors In Simulated And Virtual Patient Encounters, Sarah Powers, Mark W. Scerbo, Matthew Pacailler, Macy Kisiel, Baillie Hirst, Ginger S. Watson, Lauren Hamel, Fred Kron

Modeling, Simulation and Visualization Student Capstone Conference

The present study assessed whether trainees display similar nonverbal and paraverbal behaviors when interacting with a simulated (SP) and virtual patient (VP). Sixty second slices of time following four interactions were rated for the presence and frequency of three nonverbal and paraverbal behaviors. Results revealed that students exhibited fewer behaviors in the VP interaction, possibly due to differences social inhibition or fidelity between the two formats.

Applicable Mitigation Strategies And Technology Propositions: Preventing Scamming In Marginalized Populations, Grace Nicole Sandhofer-Adams

Cybersecurity Undergraduate Research Showcase

This essay serves as a proposal for new technology and mitigation against the scamming of marginalized individuals (i.e., those over the age of 65). Research supports this outline, giving background to the types of scams, and prevention strategies currently seen in the cybersecurity landscape. It is evident that the methods we currently use to combat scamming attacks are not effective, therefore, I propose a new solution. This proposed telecommunications strategy is necessary to prevent scamming of all internet users, no matter the device. This telecommunication strategy would use artificial intelligence and machine learning to constantly improve its detection over time, …

“People Like Me Get Left Out”: A Critique Of Feminist Movement Organizing Practices Through Access Audits Of Coalitional Spaces In Norfolk, Virginia, Megan Callahan-Palko

Institute for the Humanities Master's Papers, Projects, and Capstones

This capstone explores the exclusionary and ableist organizing and protest practices of social justice movements. Digital protest has become a solution to the problem of access, and has morphed into a sentencing of separation that is difficult to escape from. As such, how we protest and participate should be self-determined. Organizers should not assume that because a person has a disability they will be participating digitally, or from the confines of their homes. Equitable physical protest access is a disability justice issue that touches at the intersections of race, gender, class, and, of course, disability. Using intersectionality, black feminist thought, …

The Association Between Vigorous Physical Activity And Alcohol Use, Christina James, Emily Junkin, Cathy Lau-Barraco

Undergraduate Research Symposium

Evidence supports a positive association between excessive exercise and alcohol use among young adults. Past research has looked at the effects of medium-intensity physical activity regarding alcohol use prevention among college students, suggesting a positive linear association between these two variables. However, prior research has primarily focused on men. Thus, questions regarding health-compromising behaviors, such as excessive drinking and exercise among women, remain to be investigated. Further, questions have been raised concerning the pattern of association between vigorous physical activity and alcohol use among men versus women. The present study aims to replicate prior research by evaluating (1) the association …

The Use Of Artificial Intelligence To Detect Students Sentiments And Emotions In Gross Anatomy Reflections, Krzysztof J. Rechowicz, Carrie A. Elzie

VMASC Publications

Students' reflective writings in gross anatomy provide a rich source of complex emotions experienced by learners. However, qualitative approaches to evaluating student writings are resource heavy and timely. To overcome this, natural language processing, a nascent field of artificial intelligence that uses computational techniques for the analysis and synthesis of text, was used to compare health professional students' reflections on the importance of various regions of the body to their own lives and those of the anatomical donor dissected. A total of 1365 anonymous writings (677 about a donor, 688 about self) were collected from 132 students. Binary and trinary …

Public Diplomacy And Foreign Policy Analysis In The 21st Century: Navigating Uncertainty Through Digital Power And Influence, Amber Brittain-Hale

Graduate Research Conference (GSIS)

In an era defined by digital networks and geopolitical risk, public diplomacy is gaining traction for global leaders to address uncertainty. This paper investigates the use of decentralized politics in public discourse and its implications for leadership. Individual global actors have increased public diplomatic efforts as a focus due to political uncertainty, particularly since 2016. The case of Ukraine and its President Ukraine's President Volodymyr Zelenskyy's use of digital and public diplomacy in the conflict with Russia emphasizes the importance of looking at individual actor impacts in international relations rather than just states. The study should concentrate on how digital …

Choices For U.S. Contributions To Nato: Stability Policing In The Age Of Multi-Domain Operations, Nathan M. Colvin

Graduate Research Conference (GSIS)

The United States Army claims they are a “force out of position” and must transform for large-scale combat operations (LSCO). The current narrative toward LSCO warfighting comes at the expense of lessons hard-won over decades of small wars and stability operations. The focus on LSCO is an oversimplification of the complexity and ambiguity of the future operating environment. The Army is trading clarity of narrative at the expense of a force balanced for both LSCO and non-LSCO operations. LSCO perspective assumes a worst-case scenario of war over more likely scenarios of continuous disruptions across a spectrum of conflict, which may …

Ddr, Cassandra Jagroop

Graduate Research Conference (GSIS)

Disarmament, Demobilisation and Reintegration (DDR) has been a facet of post-conflict resolution since the 1980s. DDR seeks to address a wide range of issues varying from security to human rights, law, elections, and governance. One of the major issues arising from a conflict region are armed groups involved in the fighting and how to handle them. These armed groups represent the deep insecurity and lack of faith the population has in the state mechanism (Rondeau 2011, 654), thus in order to move ahead in the post-conflict situation the issue of armed groups needs to be tackled. The evolution of warfare …

Community Healthcare Providers’ Perspectives On Hiv Pre-Exposure Prophylaxis (Prep) Use Among Black Women, Kayla Pitchford, Sylvia Shangani, Charlotte Dawson, Kristin Heron

College of Sciences Posters

The most at-risk population among women for HIV diagnosis in the U.S. are Black women, who account for 61% of all new HIV cases. Pre-exposure prophylaxis (PrEP) is a safe and effective HIV prevention method for people at risk of HIV acquisition. Despite being disproportionately affected by HIV, Black women’s knowledge, perceived benefits, and uptake of PrEP remain low. The socio-ecological model may be useful for understanding why there is a low uptake of PrEP among Black women by examining the complex interplay between individual, relationship, community, and societal factors. The current study used the socio-ecological framework to explore provider …

Examining The Impact Of De-Escalation Training Among Emergency Department Nurses, Jonathan Recchi, Jeffrey N. Doucette, Janice E. Hawkins

College of Health Sciences Posters

Workplace violence is a growing concern for US nurses, especially in the context of COVID-19 and patient incivility. De-escalation training can help mitigate high-risk incidents, but its psychological benefits are not well understood. This study aimed to determine if de-escalation training for emergency department nurses provided psychological benefit. This pre-experimental pre-test, post-test study evaluated nurse confidence in coping with patient aggression, caregiver resiliency, professional quality of life, and intention to stay with the organization. Participants completed a pretest survey, attended a two-hour verbal de-escalation training via zoom, and then completed the posttest survey. The study showed that attending the two-hour …

When Diversity Measures Are Nonequivalent: Advice For Practitioners, Kristen Denae Eggler, Jeffrey Olenick, Eric A. Surface, Jamie Ousterout

College of Sciences Posters

When addressing diversity, equity, and inclusion, researchers and organizations often focus on group differences in outcomes of interest. However, groups do not always interpret surveys in the same way, causing measurement nonequivalence. Measurement nonequivalence makes it difficult, if not impossible, to compare group differences presenting a problem for how conclusions are drawn. To better understand group differences in survey responding, the current study assessed measurement invariance across five diversity-related measures using the methods outlined by Nye and colleagues (Nye et al., 2019; Somaraju et al., 2022). Data were collected across three organizations (N = 732) from different industries (i.e., …

Equine-Assisted Psychotherapy (Eap) In The Treatment Of Military Service Members With Ptsd And/Or Tbi: A Pilot Study, Kimberly Freisenbruch, Carolyn Rutledge

College of Health Sciences Posters

Military members, whether active duty, retired, or separated from service, are at increased risk for developing physical and mental disabilities due to their military service, especially if combat was involved. Equine-assisted psychotherapy (EAP) is a therapeutic intervention that uses horses, trained equine therapists, and mental health professionals in a non-riding environment. Horses respond to very slight changes in their environment, and these responses may help to provide insight into how EAP patients communicate, set boundaries, and confront issues created by TBI and PTSD-related injuries.

The purpose of this study was to ascertain the efficacy of equine therapy on military members’ …

Can We Predict Who Tries E-Cigarettes?, Samantha A. Fitzer, Joe Flores, James M. Henson

College of Health Sciences Posters

Background: Since the emergence of e-cigarettes in the United States in 2007, the aerosol-delivery devices have become the most commonly used tobacco product among U.S. youth. This trend puts decades of work deterring young people from cigarettes in jeopardy and increases the risk of exposing a new generation of young people to nicotine. Researchers need to know what behaviors to target and who is at greatest risk in order to act upon the U.S. surgeon general’s 2018 call to action.

Method: This study examined a variety of factors that have the potential to differentiate college students on their e-cigarette use. …

Resource Needs And Disparities Among University Members During Covid-19, Raksha Kandlur Ma, Nathan Hager Ms, Catherine Glenn Phd

College of Sciences Posters

Prior studies suggest that campus closures due to COVID-19 adversely impacted the well-being of college and university members. However, no research has examined the resources needed to assist university members as they return to pre-pandemic activities. The current study examined: (1) the resources university members wanted to assist their transition back to in-person activities, (2) their access to these resources, and (3) differences in access among various demographic groups, including those from minoritized backgrounds.

Participants completed a novel Wants and Access Questionnaire to gauge their desires for and access to various campus and community resources. The study included 471 university …

Examining The Experience Of Teen-To-Teen Crisis Line Work For Adolescent Volunteers: A Pilot Study, Taylor Kalgren Bs, Catherine R. Glenn Phd, Raksha Kandlur Ms, Kelsie Allison Ms, Annie Duan Bs, Cheryl Karp, Morgan Leets, Sandipan Dutta Phd, Madelyn Gould Phd, Mph

College of Sciences Posters

Suicidal thoughts and behaviors are high and increasing among youth. Crisis lines are one of the oldest downstream approaches for suicide prevention, which have demonstrated effectiveness for adults and preliminary effectiveness for youth. Teen-to-teen (t2t) crisis lines are a unique resource where adolescent volunteers help their similarly aged peers (through texts, chats, calls, and emails). However, no research to date has examined the impacts of t2t crisis line volunteering on the youth. The goal of this pilot study is to begin to evaluate the experience of t2t crisis lines for the youth volunteers. Adolescent (n=20, ages 15-20) volunteers were recruited …

Accounting Reporting Complexity, Audit Engagement Partner Mandatory Rotation, And Audit Quality, Clement Chen, Zhenfeng Liu, Wenye Tang, Ling Tuo

Accounting Faculty Publications

This paper investigates the influence of a firm's accounting reporting complexity (ARC) on financial statement audit quality. We predict and find that there is a non‐linear relationship between a firm's ARC and audit quality. Specifically, a more complex accounting environment—measured by ARC—leads to higher quality audits, but this effect diminishes when ARC continues to increase. Further analyses reveal that the effect is more salient among client firms that do not purchase non‐audit services (NAS). We also examine whether ARC affects audit quality in the circumstance of mandatory audit partner rotation. Empirical results show a moderating effect of ARC on the …

Will Networks In Military Life Influence Veteran’S Entrepreneurial Intention? Institutional Impacts On Transitional Entrepreneurship, Jamil Kreugel, Timiry R. Tian, Nicklous Salzman, Jing Zhang

College of Business (Strome) Posters

This research studies how military and civilian networks influence military veteran’s perceived resource acquisition and consequently their entrepreneurial intention (EI). Building on social network theory and institutional theory, we argue that the effects of a network consisting of military ties may be more limited than its civilian counterpart in increasing veteran’s EI. The institutional gap between military and civilian life increases the difficulty of making the transition and therefore disconnects the link between one’s military network and their EI via resource acquisition. Using questionnaire survey data collected from 261 veteran students in a public university in the US, we found …

Investigating The Impacts Of Connected Vehicles On Driving Aggressiveness And Situational Awareness In Highway Crash Scenarios: A Driving Simulator Study, Abdalziz Alruwaili

College of Engineering & Technology (Batten) Posters

Psychological factors such as aggressiveness and situational awareness can impact driving performance. Connected vehicles (CV), equipped with advanced sensors and able to communicate safety messages to drivers, have the potential to influence driving performance by altering drivers’ aggressiveness and situational awareness. This paper aims to investigate the impacts of the CVs on driving aggressiveness and situational awareness in highway crash scenarios where a primary crash has already occurred, and a second crash may occur as a result. To achieve this goal, a driving simulator experiment was conducted, and questionnaires focused on driving aggressiveness and CV effectiveness were distributed. Structural equation …

Differences In Relationship And Sexual Satisfaction And Social Support Between Only Lesbian, Mostly Lesbian, And Bisexual Women, Meredith I. Turner, Cassidy M. Sandoval, Charlotte A. Dawson, Kristin E. Heron

College of Sciences Posters

Research suggests relationship and sexual satisfaction and social support are correlated with components of well-being such as anxiety, depression, and physical health. Differences in relationship and sexual satisfaction and social support have been identified between sexual minority women (SMW; i.e., lesbian and bisexual) and heterosexual women. However, classifying SMW into a single group may mask important differences. Further research is needed to better understand the differences in relationship and sexual satisfaction and social support between subgroups of SMW. Thus, the purpose of the present study was to examine differences in these constructs between women who identify as only lesbian, mostly …

Hypotheses Related To Anting By Birds, Helena Flores

2023 REYES Proceedings

“Anting” is a widespread behavior among bird species and mammals. Due to the various characteristics of this behavior, numerous hypotheses have been proposed to explain it. This behavior can be classified as “active”, in which birds take a bill full of ants and rub them into their feathers, or “passive” when birds let ants wander through their plumage. The hypotheses state that anting may be performed as an (1) antiparasitic behavior, for (2) feather grooming, as a way of (3) food preparation or to (4) decrease skin irritation during molt, even as a (5) sensory stimulation tool. This review compiles …

Forming The Perception Of Wic Infant Feeding Recommendations: A Qualitative Study, Emily Fisher, Kathryn Wouk, Priyanka Patel, Chuanyi Tang, Qi Zhang

Community & Environmental Health Faculty Publications

Nearly half of newborns in the United States are enrolled in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC). Promoting breastfeeding is a programmatic priority, although formula vouchers are provided for those who do not exclusively breastfeed. Previous literature suggests that participant perception of WIC’s breastfeeding recommendations is a significant factor predicting breastfeeding initiation, duration, and exclusivity outcomes. However, little is known about how participants’ perceptions of WIC’s breastfeeding recommendations are formed. To address this knowledge gap, we conducted a qualitative pilot study in Nevada, interviewing 10 postpartum WIC mothers and 12 WIC staff who had interacted …

Cohn et al. (2019) conducted a wallet drop experiment in 40 countries to measure "civic honesty around the globe," which has received worldwide attention but also sparked controversies over using the email response rate as the sole metric of civic honesty. Relying on the lone measurement may overlook cultural differences in behaviors that demonstrate civic honesty. To investigate this issue, we conducted an extended replication study in China, utilizing email response and wallet recovery to assess civic honesty. We found a significantly higher level of civic honesty in China, as measured by the wallet recovery rate, than reported in the …
