Understanding The Potential Sources Of Bacteria And Turbidity Pollution In The Edisto Island Watershed, Brynne Sumner

All Theses

Anthropogenic pollution introduces contaminants, such as pathogenic bacteria and turbidity, into coastal watersheds. These contaminants are the major contributors to water quality impairments in the three sub-watersheds encompassing Edisto Island and the Town of Edisto Beach (hereafter referred to as the Edisto Island Watershed), located within the ACE Basin, South Carolina, USA. With 18 locations impaired for fecal bacteria and 19 for turbidity on the 2024 South Carolina 303(d) list of impaired waters, the Edisto Island Watershed offers valuable insights into the water quality challenges rural coastal communities face.

This study aimed to identify the sources of fecal bacteria and …

Evaluation Of Ostomy Pouching Change Practices Among Hospital-Based And Community-Based Nurses, Hannah Gerlach

All Theses

An estimated 725,000 to 1 million Americans are living with an ostomy and depend on ostomy pouching systems as part of their daily care. Effective ostomy management requires regular pouch changes and consistent skin care to prevent peristomal skin complications. Many individuals living with an ostomy face long-term challenges in managing their ostomy care, which can negatively affect their health-related quality of life. There is a need to understand how professional experience across different care environments, such as hospital-based and community-based settings, influences ostomy nursing care practices.

This study evaluates how nurses working in hospital-based settings and community-based settings perform …

Fixed Points For Fitted Lines, David L. Farnsworth

Articles

For many fitting methods for lines in the plane, each observation possesses an associated point in the plane, or at infinity for particular observations. These associated points are called “fixed points,” because properly chosen replacement points for the originally selected observation create other fitted lines that contain the same fixed point. Simple linear regression and orthogonal least-squares regression are investigated as examples. The phenomenon has been previously noted for simple regression, where the properly selected replacement points are related to regression diagnostics and the determination of outliers. Orthogonal regression lines are fundamental to principal component analysis. Mechanical devices for simple …

Some Results About Orthogonal Least-Squares Lines, Steven J. Kilner, David L. Farnsworth

Articles

A set of quantitative bivariate data is augmented with one additional point. Orthogonal least-squares fitting is used for the original set and the augmented set. The possible locations of the two lines, the points of means of the two sets, and the augmenting point are examined.

Flow And Professional Identity Through Lived Experiences Of Doctoral Students In An Online Immersive Instructional Framework, Leticia De Leon

Teaching and Learning Faculty Publications

This qualitative phenomenological study explored the lived experiences of doctoral students engaged in an immersive instructional framework within an online course on Adult Learning Strategies. The purpose was to examine how immersive design elements (De Leon, 2020) and flow theory as defined through Csikszentmihalyi’s (1990) and Shin’s (2006) helped participant engagement via enjoyment, telepresence, focused attention, and time distortion. Participants completed five narrative journals across two immersive modules designed with multimodal, authentic, interactive, and autonomous elements. Data analysis followed Moustakas’ (1994) phenomenological reduction, including bracketing, horizontalizing, thematic clustering, and a synthesized essence of experience. Results revealed that students experienced flow …

Decision-Making Criteria In Polygenic Embryo Screening: A Survey Of Reproductive Medicine Physicians, Rémy A Furrer, Aayushi Gandhi, Dorit Barlevy, Shai Carmi, Todd Lencz, Stacey Pereira, Gabriel Lázaro-Muñoz

Center for Medical Ethics and Health Policy Staff Publications

Purpose: Polygenic embryo screening (PES) examines embryos for their genetic likelihood of developing complex conditions and traits. The commercialization of PES places reproductive endocrinologists and infertility specialists (REIs) as the primary decision-makers in its use, despite professional guidelines cautioning that PES is not ready for clinical use.

Methods: This survey examines how 152 US REIs perceive and approach potential clinical decision-making scenarios regarding the use of PES.

Results: REIs were more likely to offer PES for medical conditions (up to 62% for cancer) than for traits (eg, 0% for skin color, 10% for body mass index). When evaluating 11 potential …

Engagement Of Understudied Populations As Community Change: The South Texas Adrc Model, Gladys E. Maestre, Neela K. Patel, Rosa V. Pirela, Robin C. Hilsabeck, Kendra Stine, Neyra García, Roberto Reyes, Omar Oropeza, Cristian Maestre, Jesus D. Melgarejo, Sarah Williams-Blangero, Ney Alliey Rodriguez, Sylvia A. Robles

School of Medicine Publications

Many populations experiencing the highest burdens of Alzheimer's disease and related dementias remain understudied, in part because traditional recruitment and retention models are insufficient to support sustained engagement. The Outreach, Recruitment, and Engagement Core (OREC) of the South Texas Alzheimer's Disease Research Center reconceptualized participant recruitment as a long-term system change in a Hispanic-majority, urban–rural region. OREC institutionalizes shared power through community advisory governance, aligns research protocols with local lived realities (through patient navigators, community health workers/promotores, and decentralized access points), and employs a data-driven feedback loop for continuous improvement. In 1 year, 46 outreach events touched 10,134 individuals (71% …

"Always Online, Never At Ease: Fear Of Missing Out (Fomo) As A Partial Mediator Between Adverse Childhood Experiences (Aces) And Physical Health, Psychological Functioning, And Psychosocial Adjustment Among College Students", Evelyn Pensamiento

Psychological Science Undergraduate Honors Theses

Adverse Childhood Experiences (ACEs) are potentially traumatic events, such as abuse, neglect, and household disruption, that occur during the first 18 years of life. ACEs have been found to be strongly linked to negative outcomes, such as poor physical health, poor mental health, low self-esteem, low emotion regulation, poor college adjustment, low life satisfaction, and low social connectedness, and high loneliness (Felitti et al., 1998; Carbonell et al., 2018; Cloitre et al., 2019; Mosley-Johnson et al., 2018; Yayan et al., 2019). Previous literature suggests that fear of missing out (FoMO) may help explain some of the negative consequences of ACEs …

An Update On The Role Of Multimodal Analgesia In Perioperative Pain Management, Whitney N. Kuwamoto, Grace C. Eddy, Edward R. Mariano, Eric S. Schwenk

Department of Anesthesiology Faculty Papers

Multimodal analgesia has become a foundational principle of acute perioperative pain management and enhanced recovery and involves the application of nonpharmacologic, pharmacologic, and/or interventional techniques. The overall goal of this approach is to apply a combination of different modalities that target discrete points along the pain pathway and thereby avoid the overreliance on opioids and associated side effects. Since our review in 2018, there have been significant developments that have prompted an updated review of multimodal analgesia. In this article, we identify and summarize important trends that influence the current approach to acute perioperative pain management as well as provide …

Ecmo Use In Infants With Bronchopulmonary Dysplasia: A Literature Review., John Ibrahim, Nicholas Carr, Franscesca Miquel Verges, Natalie Rintoul, Robert Digeronimo, John M. Daniel Iv, Sarah Keene, Burhan Mahmood

Manuscripts, Articles, Book Chapters and Other Papers

Bronchopulmonary dysplasia (BPD) is a leading cause of chronic respiratory failure in infants. Severe BPD is associated with prolonged mechanical ventilation, pulmonary hypertension, and high morbidity and mortality. As disease severity increases, extracorporeal membrane oxygenation (ECMO) is being reconsidered as a potential rescue therapy. Historically, ECMO has been reserved for neonates with reversible respiratory failure and those who required mechanical ventilation for less than 14 days, while infants with BPD were excluded. However, advancements in ECMO technology, anticoagulation strategies, and ventilatory management have led to a reassessment of its role in this population. Emerging reports suggest ECMO may serve as …

Beyond Conventional Construction A Sustainability Assessment Of 3d-Printed Concrete For Multi-Family Housing, Jennifer Candelier

Theses

The construction industry continues to face significant challenges, including labor shortages, increasing housing demand, rising material costs, and pressure to reduce environmental impacts. Three-dimensional printed concrete (3DPC) has emerged as a potential alternative to conventional construction methods by improving automation, material efficiency, and construction productivity. However, existing research has focused primarily on single-family applications, leaving limited understanding of its feasibility for multi-family residential construction. This study evaluates whether 3D printed concrete can become a standardized construction method for multi-family residential buildings by comparing it with conventional concrete masonry unit (CMU) construction. A comparative, performance-based methodology was developed using two equivalent …

Harnessing Airborne And Spaceborne Lidar For Large-Area Assessment Of Canopy Structural Complexity, Tahrir Ibraq Siddiqui

Theses

Forests play a vital role in global carbon cycling, biodiversity conservation, and the provision of ecosystem services. Accurate quantification of forest carbon sequestration rates – or forest production – therefore is essential for understanding ecosystem dynamics and informing sustainable forest management practices. Light detection and ranging (LiDAR) systems, as an active remote sensing modality, have emerged as a powerful tool for capturing detailed structural information of forests. Studies employing terrestrial LiDAR demonstrated that canopy structural complexity (CSC) metrics are strongly correlated with forest production at stand to landscape scales. While terrestrial LiDAR systems provide highly detailed maps of internal canopy …

Population Inference Of Compact Binaries With Eccentricity, Muhammad Zeeshan

Theses

Gravitational waves opened a new window to study the properties of compact binary systems, providing insights into their astrophysical formation and evolution. Initially, population studies relied on mass and spin distributions to distinguish between isolated, dynamical, and hierarchical merger channels; however, orbital eccentricity offers a complementary probe of binary formation scenarios. Historically, eccentricity received limited attention due to the lack of eccentric wave- form models and the absence of strong observational evidence within the LIGO–Virgo–KAGRA sensitivity band. A growing catalog, recent advances in eccentric waveform modeling, and analyses reporting candidates consistent with non-zero eccentricity motivate a systematic population-level study with …

Impact Of Chiral Chain Conformations On The Self-Assembly Of Helical Polymers, Michael J. Grant

Theses

Polymers are a soft material with diverse applications across a spectrum of technologies including, but not limited to, packaging, drug-delivery, optics, lithography and templating. This ubiquity stems from over a century of in-depth theoretical and experimental investigations relating polymer size, stiffness and architecture to their emergent material properties. Interestingly, unlike small organic molecules where solution behavior is predominantly a function of hydrophobicity, in polymers, adjusting the aforementioned features can have a dramatic impact on their interactions with neighboring molecules. In turn, this allows for a tunable parameter space enabling the ability to achieve specific engineering goals. Yet, while the impact …

Characterizing Heavy Water Displacement In Molecular Sieve Drying Beds For Practical Trace Tritium Capture Methods, Brandon M. Massett

Theses

Tritium plays a crucial role in nuclear fusion power plant designs, and adsorption beds are essential tools for managing tritiated water vapor. A series of tests was performed to investigate whether a saturated adsorption bed preferentially adsorbs heavy water vapor. The design of passive tritium control systems could potentially rely on adsorption beds preferentially trapping heavier isotopologues of water. This work investigates the displacement phenomenon and the effects of carrier gas superficial velocity on bed performance. Significant displacement was observed when a humid stream containing heavy water was diverted through a bed pre-saturated with light water, as indicated by changes …

2020-Current year OA Pubs

We examined cognitive changes associated with several neuropathologic entities, alone and in combination. We studied 808 participants from the National Alzheimer's Coordinating Center to assess associations between neuropathologic diagnoses (from autopsy) and neuropsychologic test scores (trajectories over time for 5 domains: overall cognition, episodic memory, attention, language, executive function). Neuropathologies included: Alzheimer disease neuropathologic change (ADNC), Lewy body disease (LBD), vascular brain injury (VBI), and limbic-predominant age-related TDP43 encephalopathy neuropathologic change (LATE-NC). Using linear mixed-effects models, we examined trajectories of cognitive decline for ADNC alone compared to ADNC plus LBD, VBI, or LATE-NC. We also examined differences between observed trajectories …

Pelagic Ecosystem Interactions Of An Offshore Longline Mussel Farm, Llucia Mascorda-Cabre, Philip Hosegood, Martin Attrill, Emma Sheehan

School of Biological and Marine Sciences

Long-term interactions of the UK's first large scale offshore mussel farm with the surrounding pelagic environment were studied to assess the farm's ecological impact. Pelagic fishes, zooplankton community and oceanographic parameters such as temperature, salinity, density, chlorophyll- α, dissolved oxygen and CDOM were quantified over seven years. Effects to oceanographic parameters were observed locally comparing samples collected on the east and west parts of the farm, evidencing turbulent mixing of the water column enhanced by the farm. There was no difference between zooplankton assemblage composition inside and outside the farm, only naturally occurring temporal changes were detected, supporting the hypothesis …

A Review Of Blue Carbon Credit Projects' Socio-Economic Activities, Nata Tavonvunchai, Holly J. Niner, Abigail Mcquatters-Gollop, Siân E. Rees

School of Biological and Marine Sciences

Coastal ‘blue carbon’ ecosystems (mangroves, seagrasses and saltmarshes) are critical for climate regulation and biodiversity, yet significant funding gaps persist in marine conservation. While blue carbon credits are increasingly used to bridge these gaps, concerns remain regarding their efficacy in delivering socio-economic benefits. Based on lessons from terrestrial carbon markets, failing to prioritise local community needs can lead to inequitable outcomes and externally mandated constraints, which undermine the legitimacy of nature-based solutions. This research seeks to add to the centralised understanding of the social dimension of blue carbon by delivering a comprehensive review of 77 publicly listed projects from global …
