Bartley, Rosario Pintos Lobo, Lauren D. Hill-Bowen, Taylor Sato, Erica D. Musser, Matthew T. Sutherland, Angela R. Laird

Psychology Faculty Publications

Background: Post-traumatic stress disorder (PTSD) is a debilitating disorder defined by the onset of intrusive, avoidant, negative cognitive or affective, and/or hyperarousal symptoms after witnessing or experiencing a traumatic event. Previous voxel-based morphometry studies have provided insight into structural brain alterations associated with PTSD with notable heterogeneity across these studies. Furthermore, how structural alterations may be associated with brain function, as measured by task-free and task-based functional connectivity, remains to be elucidated.

Methods: Using emergent meta-analytic techniques, we sought to first identify a consensus of structural alterations in PTSD using the anatomical likelihood estimation (ALE) approach. Next, we generated functional …

For Whom The Bell Tolls: Psychopathological And Neurobiological Correlates Of The Dna Methylation Index Of Time-To-Death, Sage E. Hawn, Xiang Zhao, Danielle R. Sullivan, Mark Logue, Dana Fein-Schaffer, William Milberg, Regina Mcglinchey, Mark W. Miller, Erika J. Wolf

Psychology Faculty Publications

Psychopathology is a risk factor for accelerated biological aging and early mortality. We examined associations between broad underlying dimensions of psychopathology (reflecting internalizing and externalizing psychiatric symptoms), PTSD, and age-adjusted GrimAge (“GrimAge residuals”), a DNA methylation biomarker of mortality risk relative to age. We also examined neurobiological correlates of GrimAge residuals, including neurocognitive functioning, blood-based biomarkers (of inflammation, neuropathology, metabolic disease), and cortical thickness. Data from two independent trauma-exposed military cohorts (n = 647 [62.9% male, M_age = 52], n = 434 [90% male, M_age = 32]) were evaluated using linear regression models to test associations between …

Rationale And Design Of An Ecological Momentary Assessment Study Examining Predictors Of Binge Eating Among Sexual Minority And Heterosexual Young Women: Protocol For The Health And Experiences In Real Life (Her Life) Study, Kristin E. Heron, Abby L. Braitman, Charlotte A. Dawson, Cassidy M. Sandoval, Lauren V. Butler, Alicia Moulder, Robin J. Lewis

Psychology Faculty Publications

Background: Previous research has identified health disparities between sexual minority and heterosexual women, including increased rates of obesity and binge eating in sexual minority women. Established predictors of binge eating behavior include negative emotions and sociocultural processes; however, these studies are generally conducted in samples of young women where sexual identity is not known or reported. There is a dearth of research evaluating how sexual minority–specific factors (eg, minority stress and connectedness to the lesbian, gay, bisexual, transgender, and queer community) may affect binge eating in sexual minority women. In addition, no studies have examined these processes in racially diverse …

A Meta-Analysis Of Associations Between Weight Bias Internalization And Conceptually-Related Correlates: A Step Towards Improving Construct Validity, Kelly A. Romano, Kristin E. Heron, Cassidy M. Sandoval, Lindsay M. Howard, Rachel I. Macintyre

Psychology Faculty Publications

Weight bias internalization (WBI), a process of weight-based self-devaluation, has been associated with adverse mental and physical health. However, there are limitations with the existing conceptualization and operationalization of WBI that raise questions about the implications of this evidence-base. To address these limitations, the present study investigated the construct validity of WBI by conducting a meta-analysis of associations between WBI (as currently operationalized) and conceptually-related correlates. Studies identified through October 2021 that provided zero-order correlations for associations between WBI and conceptually-related constructs were examined. Meta-regression determined whether these associations differed across WBI measures and demographic (age, sex/gender, race, BMI) and …

Associations Between Body Dissatisfaction And Relationship Functioning Among Same-Sex Female Couples: An Actor-Partner Interdependence Model, Cassidy M. Sandoval, Kelly A. Romano, Kristin E. Heron, Charlotte A. Dawson, Tiphanie G. Sutton, Barbara A. Winstead, Robin J. Lewis

Psychology Faculty Publications

Nearly all past research about body dissatisfaction and romantic relationship factors is among heterosexual couples; little is known about these associations in sexual minority couples. The present study aimed to fill gaps in the current literature by using actor-partner interdependence models (APIMs) to examine dyadic patterns of association between body dissatisfaction and different aspects of relationship functioning among same-sex female couples. Participants were 163 same-sex female romantic dyads (326 women) between the ages of 18-35 years who completed measures of body dissatisfaction and relationship factors. Results from significance testing of actor and partner effects indicated higher levels of women's own …

The Relationship Between Enterprise Risk Management And Cost Of Capital, Muhammad Kashif Shad, Fong-Woon Lai, Amjad Shamim, Michael Mcshane, Sheikh Muhammad Zahid

Finance Faculty Publications

This paper investigates the effect of enterprise risk management (ERM) implementation on the cost of capital (cost of debt, cost of equity, and weighted average cost of capital) for the oil and gas industry. The research is conducted using panel data analysis from 2008-2017 for 41 oil and gas companies publicly listed on the Bursa Malaysia. ERM implementation data is collected from company annual reports, while the cost of capital data is obtained from Thomson Reuters DataStream. The results indicate that an increase in the level of ERM implementation reduces the cost of capital, which we argue is one mechanism …

Dynamic Modeling Of Inland Flooding And Storm Surge On Coastal Cities Under Climate Change Scenarios: Transportation Infrastructure Impacts In Norfolk, Virginia Usa As A Case Study, Yawen Shen, Navid Tahvildari, Mohamed M. Morsy, Chris Huxley, T. Donna Chen, Jonathan Lee Goodall

Civil & Environmental Engineering Faculty Publications

Low-lying coastal cities across the world are vulnerable to the combined impact of rainfall and storm tide. However, existing approaches lack the ability to model the combined effect of these flood mechanisms, especially under climate change and sea level rise (SLR). Thus, to increase flood resilience of coastal cities, modeling techniques to improve the understanding and prediction of the combined effect of these flood hazards are critical. To address this need, this study presents a modeling system for assessing the combined flood impact on coastal cities under selected future climate scenarios that leverages ocean modeling with land surface modeling capable …

Exploring The Spatially Heterogeneous Effects Of The Built Environment On Bike-Sharing Usage During The Covid-19 Pandemic, Hongtai Yang, Zishuo Guo, Guocong Zhai, Linchuan Yang, Jinghai Huo

Civil & Environmental Engineering Faculty Publications

Bike-sharing holds promise for available and healthy mobility services during COVID-19 where bike sharing users can make trips with lower health concerns due to social distancing compared to the restricted transportation modes such as public transit and ridesharing services. Leveraging the trip data of the Divvy bike-sharing system in Chicago, this study explores spatially heterogeneous effects of built environment on bike-sharing usage under the pandemic. Results show that the average weekly ridership declined by 52.04%. To account for the spatially heterogeneous relationship between the built environment and the ridership, the geographically weighted regression (GWR) model and the semiparametric GWR (S-GWR) …

Arithfusion: An Arithmetic Deep Model For Temporal Remote Sensing Image Fusion, Md Reshad Ul Hoque, Jian Wu, Chiman Kwan, Krzysztof Koperski, Jiang Li

Electrical & Computer Engineering Faculty Publications

Different satellite images may consist of variable numbers of channels which have different resolutions, and each satellite has a unique revisit period. For example, the Landsat-8 satellite images have 30 m resolution in their multispectral channels, the Sentinel-2 satellite images have 10 m resolution in the pan-sharp channel, and the National Agriculture Imagery Program (NAIP) aerial images have 1 m resolution. In this study, we propose a simple yet effective arithmetic deep model for multimodal temporal remote sensing image fusion. The proposed model takes both low- and high-resolution remote sensing images at t₁ together with low-resolution images at a …

Environmental And Social Determinants Of Leisure-Time Physical Activity In Children With Autism Spectrum Disorder, Jihyun Lee, Sean Healy, Justin A. Haegele

Human Movement Studies & Special Education Faculty Publications

Background: It is increasingly recognized that children's physical activity behaviors are shaped by neighborhood environment factors and their parent's support. However, these factors have been scarcely studied among children with autism spectrum disorder (ASD), a population at risk of inactivity.

Objective: This cross-sectional survey study was designed to examine how neighborhood environmental factors and parental support are related to physical activity levels of children with ASD. Also, this study examined if the relationship between the environment and physical activity is modified by demographic factors and COVID-19 related concerns.

Methods: An online survey was completed by parents of children with ASD …

Eye Movement And Pupil Measures: A Review, Bhanuka Mahanama, Yasith Jayawardana, Sundararaman Rengarajan, Gavindya Jayawardena, Leanne Chukoskie, Joseph Snider, Sampath Jayarathna

Computer Science Faculty Publications

Our subjective visual experiences involve complex interaction between our eyes, our brain, and the surrounding world. It gives us the sense of sight, color, stereopsis, distance, pattern recognition, motor coordination, and more. The increasing ubiquity of gaze-aware technology brings with it the ability to track gaze and pupil measures with varying degrees of fidelity. With this in mind, a review that considers the various gaze measures becomes increasingly relevant, especially considering our ability to make sense of these signals given different spatio-temporal sampling capacities. In this paper, we selectively review prior work on eye movements and pupil measures. We first …

Streaminghub: Interactive Stream Analysis Workflows, Yasith Jayawardana, Vikas G. Ashok, Sampath Jayarathna

Computer Science Faculty Publications

Reusable data/code and reproducible analyses are foundational to quality research. This aspect, however, is often overlooked when designing interactive stream analysis workflows for time-series data (e.g., eye-tracking data). A mechanism to transmit informative metadata alongside data may allow such workflows to intelligently consume data, propagate metadata to downstream tasks, and thereby auto-generate reusable, reproducible analytic outputs with zero supervision. Moreover, a visual programming interface to design, develop, and execute such workflows may allow rapid prototyping for interdisciplinary research. Capitalizing on these ideas, we propose StreamingHub, a framework to build metadata propagating, interactive stream analysis workflows using visual programming. We conduct …

D-Lib Magazine Pioneered Web-Based Scholarly Communication, Michael L. Nelson, Herbert Van De Sompel

Computer Science Faculty Publications

The web began with a vision of, as stated by Tim Berners-Lee in 1991, “that much academic information should be freely available to anyone”. For many years, the development of the web and the development of digital libraries and other scholarly communications infrastructure proceeded in tandem. A milestone occurred in July, 1995, when the first issue of D-Lib Magazine was published as an online, HTML-only, open access magazine, serving as the focal point for the then emerging digital library research community. In 2017 it ceased publication, in part due to the maturity of the community it served as well as …

Scholarly Big Data Quality Assessment: A Case Study Of Document Linking And Conflation With S2orc, Jian Wu, Ryan Hiltabrand, Dominik Soós, C. Lee Giles

Computer Science Faculty Publications

Recently, the Allen Institute for Artificial Intelligence released the Semantic Scholar Open Research Corpus (S2ORC), one of the largest open-access scholarly big datasets with more than 130 million scholarly paper records. S2ORC contains a significant portion of automatically generated metadata. The metadata quality could impact downstream tasks such as citation analysis, citation prediction, and link analysis. In this project, we assess the document linking quality and estimate the document conflation rate for the S2ORC dataset. Using semi-automatically curated ground truth corpora, we estimated that the overall document linking quality is high, with 92.6% of documents correctly linking to six major …

The Dsa Toolkit Shines Light Into Dark And Stormy Archives, Shawn Morgan Jones, Himarsha R. Jayanetti, Alex Osborne, Paul Koerbin, Klein Martin, Michele C. Weigle, Michael L. Nelson

Computer Science Faculty Publications

Web archive collections are created with a particular purpose in mind. A curator selects seeds, or original resources, which are then captured by an archiving system and stored as archived web pages, or mementos. The systems that build web archive collections are often configured to revisit the same original resource multiple times. This is incredibly useful for understanding an unfolding news story or the evolution of an organization. Unfortunately, over time, some of these original resources can go off-topic and no longer suit the purpose for which the collection was originally created. They can go off-topic due to web site …

Theory Entity Extraction For Social And Behavioral Sciences Papers Using Distant Supervision, Xin Wei, Lamia Salsabil, Jian Wu

Computer Science Faculty Publications

Theories and models, which are common in scientific papers in almost all domains, usually provide the foundations of theoretical analysis and experiments. Understanding the use of theories and models can shed light on the credibility and reproducibility of research works. Compared with metadata, such as title, author, keywords, etc., theory extraction in scientific literature is rarely explored, especially for social and behavioral science (SBS) domains. One challenge of applying supervised learning methods is the lack of a large number of labeled samples for training. In this paper, we propose an automated framework based on distant supervision that leverages entity mentions …

A Synthetic Prediction Market For Estimating Confidence In Published Work, Sarah Rajtmajer, Christopher Griffin, Jian Wu, Robert Fraleigh, Laxmann Balaji, Anna Squicciarini, Anthony Kwasnica, David Pennock, Michael Mclaughlin, Timothy Fritton, Nishanth Nakshatri, Arjun Menon, Sai Ajay Modukuri, Rajal Nivargi, Xin Wei, Lee Giles

Computer Science Faculty Publications

[First paragraph] Concerns about the replicability, robustness and reproducibility of findings in scientific literature have gained widespread attention over the last decade in the social sciences and beyond. This attention has been catalyzed by and has likewise motivated a number of large-scale replication projects which have reported successful replication rates between 36% and 78%. Given the challenges and resources required to run high-powered replication studies, researchers have sought other approaches to assess confidence in published claims. Initial evidence has supported the promise of prediction markets in this context. However, they require the coordinated, sustained effort of collections of human experts …

Application Of Optimization Techniques In Corporate Cash Management, Venkateswara Reddy Dondeti

Theses and Dissertations in Business Administration

For any individual person or firm, there is a trade-off between carrying too much or too little cash on hand to meet the day-to-day transactions demand for cash. The BAT model, named after three eminent economists, Baumol, Allais, and Tobin, is the foundation for almost all cash management models in use today. The goal of the BAT model is to minimize the total costs involving the brokerage fees and the opportunity cost of interest lost on the cash held on hand. The brokerage fees are incurred in connection with the transactions for liquidating securities and converting them into cash. The …

Intention-Behavior Discrepancies For Alcohol Consumption Among College Students, Emily Kaye Junkin

Psychology Theses & Dissertations

Unplanned drinkers may experience elevated risk for drinking-related harm. Research examining unplanned drinking focuses on the unplanned nature of a drinking episode (i.e., did the student drink when no drinking was planned), yet this does not capture the importance of the unintended quantity consumed. For instance, a discrepancy between drinking intentions and actual consumption has the potential to differentially impact alcohol-related outcomes beyond what is accounted for by unplanned drinking episodes. Further, research has not investigated how college students’ unintended drinking is associated with alcohol-related consequences. Moreover, utilization of protective behavioral strategies (PBS) has been shown to decrease negative outcomes …

How Leader And Follower Mindfulness Relate To Performance And Ocb Through Conversation Quality And Empathy: A Moderated Mediation Model, Arianna White-Levatich

Psychology Theses & Dissertations

Interest within the organizational research community regarding mindfulness has recently surged. Little research, however, has examined how employees’ mindfulness may influence interactions between leaders and followers. This study examined how followers’ trait mindfulness related to two specific aspects of dyadic interactions: leader – member conversational quality (LMCQ) and follower empathy toward a leader. Further, the study examined how this influence extended (via LMCQ and leader-oriented empathy) to task performance and organizational citizenship behavior (OCB), two important workplace outcomes for followers. Leader mindfulness was also expected to have a significant influence on the relationships, in that it was expected to strengthen …

The Impact Of A Crisis Intervention Team Program On Psychiatric Boarding, Kurtis Hooks

Counseling & Human Services Theses & Dissertations

Psychiatric boarding is the phenomenon of housing individuals in emergency departments while awaiting access to mental health services in the community. The expansion of psychiatric boarding is attributed to continued deinstitutionalization and under-resourcing of mental health services. Psychiatric boarding is also associated with deleterious outcomes for individuals in need of access to behavioral health services, facilities. There is limited research on programmatic efforts to reduce psychiatric boarding as it pertains to Crisis Intervention Team programs colocated in medical settings. Crisis Intervention Team (CIT) programs are community-based, multi-stakeholder partnerships that include dedicated assessment centers crisis response and referral. This study utilized …

Towards Characterizing Adversarial Opportunity And Behavior In Critical Infrastructure Network, Md Sharif Ullah

Electrical & Computer Engineering Theses & Dissertations

The growth of information and communication technology is constantly revolutionizing various domains, e.g., energy utility systems, healthcare, the internet of things, etc. This inception of widespread cyber technology enables reliability and first operability of the system, yet simultaneously imposed a risk of significant impact due to disruption of safe and secure operation. The attack surface is expanding, creating a cyber exposure gap which indicates a higher threat landscape and increased risk of compromise. Motivated by this increased threat exposure, this dissertation investigates the attack surface as a static and dynamic indicator of adversary propagation, seeking an efficient modeling paradigm to …

Mobilizing Discomfort For Water Security As A Human Right: A Newspaper Analysis Of Social Conflict In South Africa, Madison Gonzalez

Graduate Program in International Studies Theses & Dissertations

There are 884 million people globally that do not have access to improved drinking water, while 2.5 billion do not have improved access to sanitation (Office of the High Commissioner for Human Rights, 2010). Those living in informal settlements and slums—what I call the ‘solidaric disaffiliated’ zones—represent one such location where individuals around the world have found themselves in a situation of neglected crisis as their geographic, economic, and social expulsion pushes them beyond the reach of opportunity and access to basic human rights such as water and sanitation. As individuals feel their dignity deteriorating due to the extreme precarity …

Interpreting Summer In The Parks In The National Capital Area Of The National Park Service, Brendan J. Kane

Human Movement Studies & Special Education Theses & Dissertations

Washington D.C. has witnessed many watershed events throughout the history of the United States of America. One of these events was the Summer in the Parks (SITP) program organized by the National Park Service (NPS) from 1968-1976. Summer in the Parks was a community-based series of events including concerts, park visits, and exhibitions designed to quell racial tensions and promote park usage. Researchers have begun chronicling SITP, but have yet to explore how the story of SITP is conveyed by park interpreters to visitors and subsequently what themes are shared to inform public understanding of the historic relationship between NPS …

Emotion Regulation Variability And Relationship Functioning In Emerging Adulthood, Laura B. Kenneally

Psychology Theses & Dissertations

Emotion regulation is a transdiagnostic factor that functions as a crucial contributor to individual well-being and social functioning. Research seeking to identify adaptive or maladaptive strategies of emotion regulation has often focused on individual strategies, though emerging evidence suggests that what constitutes “adaptive” regulation is often context-dependent. Having a large repertoire of emotion regulation strategies that one is willing to use at different rates has been termed “emotion regulation variability,” and has been linked to positive individual outcomes. While the benefits of emotion regulation variability have been demonstrated on an individual level, the impact on romantic relationships has yet to …

What Is An Effective Way To Measure Arterial Demand When It Exceeds Capacity?, Mecit Cetin, Hong Yang, Kun Xie, Giridhar Kattepogu, Behrouz Salahshour

Civil & Environmental Engineering Faculty Publications

This project focused on developing and evaluating methods for estimating demand volume for oversaturated corridors. Measuring demand directly with vehicle sensors is not possible when demand is larger than capacity for an extended period, as the queue grows beyond the sensor, and the flow measurements at a given point cannot exceed the capacity of the section. The main objective of the study was to identify and develop methods that could be implemented in practice based on readily available data. To this end, two methods were proposed: an innovative method based on shockwave theory; and the volume delay function adapted from …

Experiences With Flood And Perceptions Of Flood Risk Among Members Of The Filipino American Community In Virginia Beach, Virginia, Anjelica Pascual Petsch

Institute for the Humanities Theses

The Filipino Americans living in Hampton Roads, Virginia have comprised of almost 2% of the region’s overall population, and 5.3% of the population in Virginia Beach, Virginia (United States Census Bureau, 2019) (Greater Hampton Roads Connects, 2021). Filipino Americans in Hampton Roads, like the rest of the population, are equally vulnerable to experiencing flooding when commuting to and from work or simply traveling around town, but previous research and surveys from the Hampton Roads Region have failed in their ability to capture this cultural diversity within perception of flood risk. In this paper, a qualitative research design was used to …
