The Associations Of Cardiovascular Disease, Physical Activity Intensities, And Measures Of Obesity On Static Balance In Middle-Aged And Older Adults, Hannah Martha Twiddy

Human Movement Studies & Special Education Theses & Dissertations

The burden of falls is widely known in older adults, though less research has targeted middle-aged adults (40-64 years of age), particularly at the population level. The purpose of this dissertation was to explore the roles of cardiovascular disease, physical activity (PA) intensity, and body anthropometrics on balance among middle-aged adults. Study 1 sought to determine if balance was impaired in middle-aged adults with poor ankle-brachial pressure index (ABPI), a marker of cardiovascular disease. Study 2 determined the associations between PA intensity with odds of having good static balance. Study 3 explored how strongly a variety of anthropometric measures, including …

Validation And Measurement Invariance Of A First-Generation College Student Identity Scale, Kelsie K. Allison

Psychology Theses & Dissertations

First-generation college students (FGCS) comprise approximately 56% of the U.S. post-secondary institution population, yet they face substantially more academic, financial, and additional unique issues than continuing-generation college students. Research on FGCS has been steadily growing in recent years, however, literature on identity for this population is sparse. To address these gaps in the literature, the aim of the current study was to adapt, validate, and establish full factorial measurement invariance across Black and White FGCS for a multidimensional quantitative measure of first-generation college student identity. The final sample included 425 current FGCS (81.2% female; M_age = 24.4 years, SD …

Other Transaction Authorities: Evaluating Innovation Policy Impact Of Alternative Contract Vehicles In The Department Of Defense, Dolores Kuchina-Musina

Pedestrian Evacuation: Vulnerable Group Member Influence On The Group Leaders’ Decision-Making And The Impact On Evacuation Time, Terra Lynne Elzie

Computational Modeling & Simulation Engineering Theses & Dissertations

As pedestrian evacuations of buildings, outdoor venues, and special events occur, dynamic interactions between pedestrians and vehicles during egress are possible. To model pedestrian and vehicle evacuations, simulation models have evolved to incorporate more realistic crowd characteristics and behaviors to provide improved results. Past studies using modeling and simulation, specifically agent-based modeling, have explored pedestrian behaviors such as decision-making, navigation within a virtual environment, group formations, intra-group interactions, inter-group dynamics, crowd behaviors such as queuing and herding, and pedestrianvehicle interactions. These studies have led to relevant insights helpful to improving the accuracy of evacuation times for normal and emergency egress …

Exploring The Workplace Climate At Police Agencies During Civil Unrest And The Factors Influencing Officers' Participation In Black Lives Matter Protesting, Joshua R. Ruffin

Sociology & Criminal Justice Theses & Dissertations

Scholars have long documented the negative relationship between police and communities of color. While these findings are of great importance, research remains limited on how connected police officers are to social justice movements (e.g., Black Lives Matter, or BLM for short) and the purposes behind why they exist. Furthermore, many studies focusing on police officer experiences tend to examine officer experiences with protesters, with limited studies focusing on their experiences with other officers during civil unrest and on the factors that influence their participation in protest movements when off duty. To help fill this gap, this study utilized semi-structured interviews …

Putin And Putnam: Interpreting Russian Military Activity Through A Three Player, Two-Level Game, Nathan M. Colvin

Modeling, Simulation and Visualization Student Capstone Conference

Is Vladimir Putin a bad strategist, perhaps irrational? Previous military activity by Russia, such as the annexation of Crimea of 2014, yielded limited international gains, at a significant economic and reputational cost. Yet as the 2022 invasion of Ukraine shows, Putin is willing to commit military power, despite the cost of sanctions and other possible retaliation. This three-player simultaneous game, originally created in June, 2021, demonstrates how domestic and international considerations of President Vladimir Putin might lead to otherwise unpredictable Russian military behavior. In this extended version of Robert Putnam’s “two-level game,” President Putin rationally uses the international venue as …

Public Goods From Private Data: An Effectiveness And Justification Dilemma For Digital Contact Tracing, Andrew Buzzell

The Journal of Sociotechnical Critique

Debate about the adoption of digital contact tracing (DCT) apps to control the spread of COVID-19 has focussed on risks to individual privacy. This emphasis reveals significant challenges to ethical deployment of DCT, but generates constraints which undermine justification to implement DCT. It would be a mistake to view this result solely as the successful operation of ethical foresight analysis, preventing deployment of potentially harmful technology. Privacy-centric analysis treats data as private property, frames the relationship between individuals and governments as adversarial, entrenches technology platforms as gatekeepers, and supports a conception of emergency public health authority as limited by individual …

Trust And Community Contexts: An Integrative Study Of Hazard Preparedness Influences In Hampton Roads, Virginia, Ogechukwu Agim Nwandu-Vincent

College of Business (Strome) Posters

Despite research findings that show the benefits of being prepared for hazard events, studies on hazard preparedness report that individuals, communities, and businesses are often poorly prepared. Several studies have determined that various factors and contexts (individual, environmental, social), social messaging, social influences, and information sources can play an important role in determining how a community prepares for and responds to a hazard (Wachinger et al., 2013; Paton & McClure, 2013; Lindell & Perry, 2012; Paton, 2007).

Higher levels of trust may lead to desired protective behaviors while lower levels may lead to low levels of engagement and compliance in …

Method one's objectives are to find an optimal location(s) for a potential Norfolk day service facility based on 1) proximity to social and health services, 2) proximity to a neighborhood that would most benefit from a day center, and …

Campus Racial Climate And Mental Well-Being Among College Students: The Role Of Feeling Valued, Sense Of Belonging, And Racial Saliency, Raksha Kandlur Ma, Catherine Glenn Phd

College of Sciences Posters

Around 73% of students report experiencing a mental health crisis during college, and 64% report dropping out for mental health reasons. Research indicates that negative campus racial climate contributes to poor mental health, but few studies have examined factors that may moderate this impact. The current study examined potential moderators of the impact of negative campus racial climate on students’ mental health, including whether: (1) feeling valued and (2) belongingness at school may buffer, or reduce, risk and (3) higher racial saliency may increase risk. Data were drawn from the Healthy Minds Study, administered to a random sample of 4,000 …

Examining A Neural Measure Of Attentional Bias To Emotional Faces In Social Anxiety And Depression, Nathan M. Hager, Matt R. Judah, Alicia L. Milam, Hannah C. Hamrick, Catherine R. Glenn

College of Sciences Posters

Cognitive theories suggest that attentional biases may contribute to both social anxiety and depression, such that attention may be biased to focus on or away from certain information (e.g., rejecting or sad images; Clark & McManus, 2002; Lemoult & Gotlib, 2019). Although research is mixed, recent studies using a neural measure called the N2pc (an event-related potential) has indicated attentional biases in social anxiety. However, little N2pc research has examined depression or co-occurring depression and social anxiety.

The current study used electroencephalography to measure the N2pc during a dot-probe task in which images of faces with emotional or neutral expressions …

Objective Measure Of Working Memory Capacity Using Eye Movements, James Owens, Gavindya Jayawardena, Yasasi Abeysinghe, Vikas G. Ashok, Sampath Jayarathna

Undergraduate Research Symposium

Human-autonomy teaming (HAT) has become an important area of research due to the autonomous systems being developed for different applications, such as remotely controlled aircraft. Many remotely controlled vehicles will be controlled by automated systems, with a human monitor that may be monitoring multiple vehicles simultaneously. The attention and working memory capacity of operators of remote-controlled vehicles must be maintained at appropriate levels during operation. However, there is currently no direct method of determining working memory capacity, which is important because it is a measure for how memory is being stored for a short term and interacting with long term …

The Relationship Between Rumination Of Covid-19 And Anxiety Levels, Madyson Hernandez, Alicia Kruzelock, Nathan Hager

Undergraduate Research Symposium

The COVID-19 pandemic has caused an increase in psychological distress among individuals around the world (Saddik et al., 2021) (Ting et al., 2021.) Rumination is a factor in increased distress caused by the pandemic. Rumination about COVID-19 may be related to the contraction and transmission of the virus. Previous literature suggests that rumination about COVID-19 increases anxiety symptoms (Jamieson, D., et al, 2021.) However, it is unknown whether time thinking about COVID-19 impacts this relationship uniquely and directly as well.

A sample of 225 undergraduate psychology students completed an online survey in April 2020 evaluating rumination, time spent thinking about …

On The Feasibility Of Speed Limits In Ocean Container Shipping, Manwo Ng

Information Technology & Decision Sciences Faculty Publications

The maritime industry is witnessing an increasingly loud call to contribute to the global trend towards environmental sustainability and decarbonization. One possible policy measure is the use of speed limits to reduce harmful emissions from ocean shipping. While the idea of slowing down ships to obey speed limits might seem intuitive, one key distinguishing characteristic of container shipping is that it is designed to adhere to a fixed, typically weekly, sailing schedule. This paper contributes to the literature investigating the feasibility of speed limits by demonstrating that speed limits are not always feasible in container shipping because of the rigid …
