The second article by Dr. Jay Malone discusses the ethical issues surrounding massive transfusion and resuscitation. Taken together, these articles address the clinical and ethical issues surrounding this very emotive and difficult topic.

Rethinking Mixed Dka-Hhs: An Extreme Presentation Of Hyperosmolar Hyperglycemic State, Sajith Silva, Umair Malik, Amin Pasha, Sujata Kambhatla

Conference Presentation Abstracts

Introduction: The American Diabetes Association (ADA) recognizes diabetic ketoacidosis (DKA) and hyperglycemic hyperosmolar state (HHS) as life-threatening hyperglycemic emergencies that can overlap clinically; approximately 10% of presentations are described as mixed DKA–HHS. Because current guidelines do not define a single “mixed” category, overlap is best understood as concurrent fulfillment of key elements of both syndromes: DKA-type anion-gap metabolic acidosis with ketonemia or ketonuria, together with HHS-type severe hyperglycemia, hyperosmolality, and dehydration. We report an extreme HHS presentation (glucose >2,100 mg/dL) with limited DKA overlap. Case Description: A 34-year-old woman with longstanding type 1 diabetes mellitus managed with an insulin pump, …

Antidepressant-Like Effects Of Extinction Learning As An Animal Model Of Behavioral Therapy, Jing Liu, Sarah E Bulin, David A Morilak

Faculty, Staff and Student Publications

Exposure-based behavioral therapy, the most effective treatment for posttraumatic stress disorder (PTSD), also reduces depressive symptoms. However, neurobiological mechanisms underlying the beneficial effects of exposure-based behavioral therapy on depression remain unknown. Our lab has established fear extinction as a rat model of exposure therapy to investigate the mechanisms underlying its therapeutic behavioral effects in chronically stressed rats. In this study, we demonstrated that extinction learning reduced immobility in the forced-swim test and reversed chronic stress-induced reduction in sucrose preference. Chemogenetic inactivation of pyramidal neurons in the ventral medial prefrontal cortex (vmPFC) prevented these antidepressant-like effects of extinction. Extinction learning enhanced …

Faculty, Staff and Student Publications

Cardiovascular diseases (CVDs) remain the leading cause of death worldwide, underscoring the need for improved strategies in diagnosis, treatment, and disease modeling. Traditional in vitro models often fall short in replicating human CV physiology, prompting efforts to advance cardiac tissue engineering and computational modeling. Among these, three-dimensional (3D) bioprinting has emerged as a transformative tool, enabling the creation of biomimetic CV constructs that more faithfully replicate native tissue structure and function. However, challenges persist in achieving appropriate mechanical properties and long-term performance of engineered CV constructs. Computational modeling offers powerful solutions to assist with these challenges, providing predictive insights into …

Are Drains After Trauma Splenectomy Associated With Organ Space Surgical Site Infections?, Stephanie Martinez Ugarte, Mokunfayo O Fajemisin, Seokhun Kim, William D Rieger, Renee W Green, Gabrielle E Hatton, Lillian S Kao

Faculty, Staff and Student Publications

Introduction: Left upper quadrant (LUQ) drain use after trauma splenectomy varies, with minimal existing data to guide practice. We aimed to investigate the association of LUQ drains with organ space surgical site infection (OS-SSI) after splenectomy. We hypothesized that LUQ drains after trauma splenectomy are associated with increased odds of OS-SSI.

Patients and methods: A retrospective study of adult blunt trauma patients who underwent splenectomy from 7/2018 to 6/2024 was performed. We excluded patients who survived < 5 days after operation, and those with an intraoperatively identified pancreatic injury. Demographics, surgical details, and drain information were abstracted from the medical record. Inverse probability of treatment weighting (IPTW) was used to balance variables between patients who did and did not receive an LUQ drain after splenectomy. Multivariable logistic regression with IPTW was performed to estimate the association of LUQ drains with OS-SSI.

Results: Of 179 patients, 68% (n = 121) were male, the median age was 38 years (interquartile range 28, 55), and 27% (n = …

An Assessment Of Green Plasma: The In Vitro Hemostatic Superiority Of A Currently Discarded Blood Product, Samantha C Redden, David J Sun, Yao-Wei W Wang, Elizabeth Hartwell, Jessica C Cardenas, Scott D Olson, Bryan A Cotton

Faculty, Staff and Student Publications

Introduction: Recent studies have linked trauma patient outcomes to the plasma donor's sex, with premenopausal females associated with improved survival and lower organ failure. Currently, green-colored plasma (due to oral contraceptive use) is removed from the donor pool. We set out to evaluate the hemostatic potential of green plasma.

Study design & methods: We obtained 90 units of plasma from our regional blood center: 30 units of visible green plasma and 60 units of standard-color plasma divided between male and female donors. We collected clinical data such as age, sex, ethnicity, and number of pregnancies. We then assessed the hemostatic …

Minimizing Musculoskeletal Injury Risk In Health Care Professionals With Education On Physical Activity Recommendations, Emma H. Foran

Honors College Theses

Working in healthcare settings that require patient handling is physically demanding - over 80% of providers involved in patient handling report work-related musculoskeletal disorders (WMSDs). Injuries or exacerbation of a previous injury may occur if the individual cannot tolerate heavy workloads. Injuries that cause lost work time or work restrictions impact the healthcare team, may alter quality of life, and impact employee income. A practical way to minimize these effects is to prevent WMSDs. Training providers to use proper body mechanics, practice patient handling, and engage in regular exercise designed to increase muscular strength and endurance through resistance training improves …

Evaluating The Rural/Urban Divide In Conservation: Methods Of Improvement In Conservation Programming Across Kentucky, Lauren Tackett

Honors College Theses

Kentucky’s lands and waterways have always defined the state. Our unique karst landscape, combined with the Appalachian Mountains and Ohio River, help characterize the state and its identity. However, across Kentucky conservation efforts within recent years have been under attack. Through legislation changes and policy challenges, various bills have sought to repeal Kentucky’s conservation efforts regarding water, soil, and land use. Furthermore, there has been a rise in environmental disasters within the state that cause long term issues for both rural and urban communities to contend with. The responsibility of land stewardship falls on a variety of entities but weighs …

Safepass: Efficient Emergency Vehicle Passage With Minimal Disruption To Traffic Flow, Osho Osho, Suchetana Chakraborty, Sajal K. Das

Computer Science Faculty Research & Creative Works

Emergency vehicle passage in congested urban networks poses a dual challenge: ensuring rapid response while minimizing disruption to surrounding traffic. This study addresses this challenge in the context of Connected Autonomous Emergency Vehicles (CA-EVs), proposing SafePass , a lightweight distributed framework for seamless CA-EV passage through decentralized, cooperative maneuvering of surrounding Connected Autonomous Non-Emergency Vehicles (CA-NEVs). At its core, SafePass employs the Target Lane Potential (TLP), a novel utility-based metric combining lane-choice utility with probabilistic gap acceptance, augmented by a cascade-aware penalty that suppresses upstream shockwaves triggered by gap-creation maneuvers. Evaluated in Simulation of Urban Mobility (SUMO) using synthetic traffic …

Long Run Effect Of Industrial Place-Based Policy On County Level Complexity, An Investigation Of The Tennessee Valley Authority, Anita Ifeyinwa Umunnah

Master's Theses

This paper studies the long-term effects of large federal investments in place-based industrial policies on regional economic development, contributing new evidence on how industrial policies shape regional local productive capabilities over time. While extensive research show that industrial policies impact regional development by advancing productive technology (capabilities), the fundamental question remains how to measure this technological transformation. The study employs the use of Economic Complexity Index (ECI) as a measure of “technological advancements” resulting from large federal investments in place-based industrial policies. Previous evaluations of such investment were based on livelihood, employment and income outcomes, with productive capability of receiving …

Resilience, Stress, And Emotion Regulation In College Students: A Moderated Mediation Model Of Tiktok Engagement, Samuel Bibat, Jon Thang, Hui Zhang, Hannah Carrie, Jessica Golden

Journal of Social, Behavioral, and Health Sciences

This study examined associations between stress, resilience, emotion regulation (ER), and TikTok use. Data were collected from 101 undergraduate students (M_age = 20.04, SD_age = 4.02) at a Midwestern private university. Participants completed self-report measures of TikTok use and intensity (i.e., emotional attachment), resilience, perceived stress, and intrapersonal and interpersonal ER. Mediation and moderated mediation analyses were conducted using PROCESS macro models. Stress mediated the relationship between resilience and TikTok use but not intensity. Interpersonal ER moderated the resilience–stress link, with higher interpersonal ER amplifying the negative association between resilience and stress, which in turn was linked …

Analysis Of Volumetric Reconstruction Methods In Archaeology, Cade O'Fallon

All-Inclusive List of Electronic Theses and Dissertations

The use of Structure from Motion (SfM) photogrammetry in archaeological projects is entering a period of transition; a method of producing 3D data that is traditionally embraced as tool for documentation is being explored for its analytic potential. One such way SfM photogrammetry can be used analytically is through the calculation of volumes using photogrammetric data. The tools exist for archaeologists to be able to create and quantify volumetric models; however, the discourse on these methods is still so new there is no consensus on the best method for conducting volumetric work. Different methods of creating and isolating volumetric space …

Microplastic Composition And Exposure Pathways In Freshwater Systems: A Multi-Matrix Comparison Between Streams And Retention Ponds In Hamilton County, In, Mya Whaley

All-Inclusive List of Electronic Theses and Dissertations

Since the early 1900s, the use of plastics has increased exponentially. The breakdown of plastic materials has exposed all ecosystems to microplastics (small particles of plastic < 5 mm), which are now ubiquitous in natural settings. Microplastics have a relatively large surface area, and many chemicals adsorb to these small particles, impacting their fate and transport of pollution. While microplastics have been found in virtually every setting on Earth, research is necessary to understand their impact on freshwater ecosystems and biogeochemical cycles. The focus of this research was to investigate microplastic compositions in crayfish, sediments, and water samples collected in streams and retention ponds. We analyzed trends in microplastic counts across different land-cover classes, waterbody types, and species, and compared concentrations among matrices to improve our understanding of microplastic exposure pathways in freshwater ecosystems. As a secondary objective, lead and arsenic concentrations were analyzed from sediment samples to investigate metal burdens and compare them to microplastic concentrations. Our findings revealed that, in general, urban streams had the highest microplastic concentrations within land cover categories, and retention ponds had higher microplastic counts than streams. Crayfish, such as F. rusticus had higher microplastic concentrations than F. virilis and F. propinquus, although these results may be influenced by study design. The most common microplastic type was fibers, and most common color was transparent. There was no significant correlation between microplastic and metal concentrations in sediments. We found crayfish to be adequate bioindicators of microplastic pollution, because they were less impacted by environmental variability than sediment and water samples. This research presents the first evidence of microplastics in our study species, F. propinquus, F. rusticus, and F. virlis. This work presents new evidence of microplastic accumulation in crayfish, sediments, and water from freshwater systems in the Midwestern United States. Microplastics were found in every sample type—crayfish, water, and sediment—across urban, rural, and forested landscapes, highlighting their pervasive distribution. The findings provide foundational data for assessing emerging ecological and human-health risks and emphasize the importance of sustained monitoring and research on MP contamination in freshwater environments.

Personality Characteristics Of Emergency Nurses And Their Subjective Fit In The Emergency Department, Jose Michael Maria

Theses & Dissertations

Nursing workforce challenges in the United States persist despite widespread recruitment and retention efforts, and the COVID-19 pandemic has further exacerbated shortages, turnover, and workforce instability. Despite interventions such as residency programs, financial incentives, and organizational initiatives, long-term retention remains inconsistent, particularly in high-demand settings like emergency departments. Ongoing issues such as overcrowding, rising patient acuity, and workforce attrition contribute to burnout, compassion fatigue, and compromised patient outcomes, perpetuating a cycle of staffing strain. Grounded in Person–Environment Fit theory, this research proposes that aligning emergency nurses’ personality traits with the specialty practice environment, the emergency department, may offer a more …

Caring For Transgender People In Healthcare: A Qualitative Descriptive Study With Nurses Working In An Acute Healthcare Setting, Gabriela Roxana Matson

Theses & Dissertations

Transgender individuals frequently encounter numerous obstacles when accessing healthcare services, including stigma, discrimination, and inadequate understanding from healthcare providers. Structural, interpersonal, and anticipation barriers significantly hinder transgender patients' access to care. Structural barriers include a lack of healthcare providers knowledgeable in transgender health and financial constraints. Interpersonal barriers involve discrimination, such as refusal to use correct pronouns or provide gender-affirming care. Anticipation barriers stem from fear of mistreatment, causing many to avoid seeking medical care altogether. Nurses play a vital role in upholding inclusive and affirming healthcare This qualitative descriptive study explored the subjective experiences of registered nurses who provided …

Bridge Building In Professional Development For Educators Working With Latinx Families: An Action Research Approach Leading To Equitable Family Engagement, Nicole Deanna Bell

Theses & Dissertations

Latinx students represent a growing population in public schools, and research highlights the importance of focusing on collectivist family engagement strategies to align with their cultural ideals. However, there is limited research on how school systems, beginning with teachers and administrators, can shift their definitions and practices to embed more collectivist-oriented strategies that foster more welcoming and inclusive spaces for Latinx families. This action-research study explored whether an asset-based lens introduced through a one-day professional development workshop could serve as a catalyst for such change. The workshop centered on participants’ storytelling, building understanding of the collectivist-individualist dichotomy, and presenting strategies …

Political Costs And Strategic Corporate Communication, Christine Cuny, Jungbae Kim, Mihir N. Mehta

Research Collection School Of Accountancy

When subject to public scrutiny, do firms strategically use advertising to reduce expected political costs? Advertising can ease public concerns, thereby reducing the pressure on politicians to act harshly against scrutinized firms and their industries. We use repeated congressional testimony by industry members as a novel way to identify political scrutiny. Our central finding is that scrutinized industries increase their advertising spending 132 percent more in the electorates of politicians overseeing the hearings than in the electorates of other politicians. Further, strategic advertising is complementary to income-decreasing accounting choices and a substitute for lobbying. Overall, our study sheds light on …

Spiritual Gentrification Amid The Rise Of Platform Urbanism: "Wanghong Temples" And Emerging Buddhist Cultural Economies In Tianzhu Road, Hangzhou, China, Han Zhang, Junxi Qian, Lily Kong

Research Collection School of Social Sciences

This study scrutinizes how the Tianzhu Road in the Lingyin Community - a peri-urban area in Hangzhou ringed by a cluster of temples that constitutes a distinct spiritual enclave - has been reworked through a two-phase gentrification process driven by the spiritual aesthetics and platform logics. Drawing on a two-month ethnography and media content analysis, this study conceptualizes spiritual gentrification as a spiritual aesthetics and culture-oriented recalibration of urban space in which spiritual elements operate as symbolic capital, attracting culturally motivated entrepreneurs and aligning the spiritual atmosphere with slow-life values as an alternative to urban modernity. In particular, platform urbanism …

The Restorative Effects Of Nature Exposure Via Virtual Reality On Well-Being, Self-Control, And Working Memory, Zoey K. Y. Eun, Hwajin Yang, Nicole R. Y. Chen, Andree Hartanto

Research Collection School of Social Sciences

The psychological benefits of nature exposure are vital for well-being in an increasingly urbanised world. While previous research has consistently demonstrated the restorative effects of natural environments on both physical and psychological health, findings on virtual nature simulations remain mixed, possibly due to the limited immersive quality of conventional displays. Virtual reality (VR), however, provides immersive visual and auditory engagement, making it a promising alternative for delivering nature-based experiences when direct exposure to real nature environments is unavailable. The present study examined the effects of VR-simulated nature on attentional and emotional restoration and self-control capacity, using a preregistered, within-subjects experimental …

A Stress-Induced Digital Escapism Framework For Understanding The Link Between Stress And Problematic Social Media Use, Hwajin Yang, Frosch Yi Xuan Quek, Xiu Hui Salin Yap, Yue Qi Germaine Tng, Gilaine Rui Ng

Research Collection School of Social Sciences

Given that stress is a significant risk factor for problematic social media use, understanding the underlying psychological mechanisms is essential. We introduce the Stress-Induced Digital Escapism (SIDE) framework, which posits that negative internal emotional responses to external stressors may increase reliance on maladaptive emotion regulation strategies that fail to alleviate distress. These processes may, in turn, strengthen escapism motives that lead to seeking emotional relief through compulsive social media use. Using structural equation modeling (N = 238), we examined three integrated psychological pathways—negative stress reactions, maladaptive emotion regulation strategies, and escapism motives—as sequential mediators linking external demands to problematic social …

Research "Junkification" Is Caused By Researchers, Not Journals, Simon Sebastian Groome, Jose C. Yong, Norman P. Li

Research Collection School of Social Sciences

Concerns about declining research quality have increasingly been framed as “junkification,” whereby academic output expands in volume while declining in epistemic value. A recent paper by Rhodes and Linnenluecke (2025) attributes this trend to changes in publishing, arguing that research quality erodes as journals and publishers become increasingly oriented toward output quantity and metrics, driven by monetization. In 2009, Nobel Laureate James Watson remarked that scientific publishing in the mid-twentieth century was both easier and of a higher standard than today (Web of Stories, 2017). If publishing is much easier of late, as Rhodes and Linnenelucke (R&L) argued, then how …
