Feedbacks Between Fjord Circulation, Mélange Melt, And The Subglacial Discharge Plume At Kangerlussuaq Glacier, East Greenland, M. Wood, I. Fenty, A. Khazendar, J. K. Willis

Faculty Research, Scholarly, and Creative Activity

In recent decades, the Greenland ice sheet has been losing ice and contributing substantially to global sea level rise. Approximately half of this recent loss is due to glacier acceleration, increasing the calving of icebergs into the ocean. This process has been linked with increased ocean heat content on the continental shelf, yet the pathways delivering this heat into Greenland's fjords and its interactions with fjord-scale processes modulating glacier ice loss are still unclear. In this study, we use a series of numerical ocean model configurations to examine feedbacks between ocean circulation, subglacial discharge, submarine glacier melt, and ice mélange …

Voices From The Field: Mental Health Therapists' Perceptions Of Collaboration With Child Protective Services Workers, Tamara P. Fields

Electronic Theses and Dissertations

The child welfare system in the United States requires collaboration across various agencies in the provision of services. Although collaboration between mental health therapists and state agencies is fundamental when the goal is to provide quality care and achieve positive outcomes for families involved with Child Protective Services (CPS), the system is characterized as complicated and fragmented. Using Bronstein’s 2003 model of interprofessional collaboration to understand the dynamics of collaboration between mental health therapists and CPS workers in Texas, this qualitative descriptive research study described mental health therapists’ perceptions of collaborating with CPS workers in delivering therapy services to CPS-involved …

Advisor Satisfaction To Support Online Student Retention, Erica K. Whiddon

Electronic Theses and Dissertations

In this dissertation, the researcher explored the relationship between satisfaction with academic advising and online student retention. Online student retention is a critical issue in the context of increasing competition for students in higher education institutions. The specific problem was that online students have lower retention rates, and the reasons students typically select online degree programs are also the reasons they drop out of their degree programs. The purpose was to identify whether students’ reported satisfaction with their advisors mediated the relationship between the existence of external personal life factors and retention. A quantitative nonexperimental causal-comparative and correlational research design …

Staying Sane In The Membrane: Neutral Sphingomyelinase 2 As A Master Regulator Of Plasma Membrane Ceramide, Zainuddin Quadri, Erhard Bieberich

Markey Cancer Center Faculty Publications

Ceramide, a key signaling sphingolipid in the plasma membrane, plays a pivotal role in fundamental cellular processes such as adhesion, polarity, and programmed cell death. The generation of plasma membrane ceramide is largely attributed to the activity of two types of sphingomyelinases: neutral sphingomyelinase 2 (nSMase2, Smpd3) and acid sphingomyelinase (aSMase, Smpd1). While many studies have explored ceramide generation following experimental activation of these enzymes, the mechanisms governing basal or steady- state ceramide levels have remained poorly understood. Using an innovative mass spectrometry approach developed in the Canals’ lab, the team has quantified the distinct contributions of nSMase2 and aSMase …

The Mitochondria As An Emerging Target Of Self- Renewal In T-Cell Acute Lymphoblastic Leukemia, Majd Al-Hamaly, Evelyn Winter, Jessica S. Blackburn

Markey Cancer Center Faculty Publications

Acute lymphocytic leukemia (ALL) is the most common leukemia in children, with the T-cell subtype (T- ALL) accounting for 15% of those cases. Despite advancements in the treatment of T-ALL, patients still face a dismal prognosis following their first relapse. Relapse can be attributed to the inability of chemotherapy agents to eradicate leukemia stem cells (LSC), which possess self-renewal capabilities and are responsible for the long-term maintenance of the disease. Mitochondria have been recognized as a therapeutic vulnerability for cancer stem cells, including LSCs. Mitocans have shown promise in T-ALL both in vitro and in vivo, with some currently in …

Potential Mental Disorder Symptoms In The Prophet Elijah: An Exegetical And Psychological Analysis Of Selected Episodes From 1 Kings 18–19, Dariusz Iwański, Thomas G. Plante

Psychology

This interdisciplinary study examines the prophet Elijah’s experiences as depicted in 1 Kings 18–19 through a multidisciplinary lens, combining theological, literary, and psychological perspectives. Drawing on literary and historical–critical methods, a biblical scholar analyzes the narrative’s linguistic and cultural dimensions, while a psychologist evaluates these findings using contemporary mental health frameworks, including the DSM-5 and models of spiritual struggle. By synthesizing these approaches, the study explores Elijah’s emotional challenges, highlighting their resonance with modern understandings of mental health and spirituality. The findings suggest that Elijah’s profound struggles—marked by triumph, despair, and renewal—offer valuable insights into the interplay of faith, vulnerability, …

Tracking Community Outreach And Engagement Activities Among National Cancer Institute-Designated Cancer Centers, Todd Burus, Caree Mcafee, Pamela Hull, Amy Leader, Christopher Mcnair

Kimmel Cancer Center Faculty Papers

The National Cancer Institute's (NCI) Cancer Center Support Grant mandates that NCI-designated cancer centers establish a Community Outreach and Engagement (COE) component to help direct efforts at reducing cancer burden within their catchment areas. Despite the critical role of COE offices, little is known about how they track and evaluate outreach activities and outcomes. We gathered information on current practices from representatives of 40 out of 65 COE offices using an online survey. Although nearly all responding centers (97.5%) tracked COE activities, no consensus existed on resources used, and satisfaction with current solutions was mixed (51.0% not satisfied). Respondents expressed …

Evaluating The Generalisability Of Region-Naïve Machine Learning Algorithms For The Identification Of Epilepsy In Low-Resource Settings, Ioana Duta, Symon M. Kariuki, Anthony Ngugi, Angelina Kakooza Mwesige, Honorati Masanja, Daniel M. Mwanga, Seth Owusu-Agyei, Ryan Wagner, J Helen Cross, Josemir W. Sander W. Sander

Population Health, East Africa

Objectives: Approximately 80% of people with epilepsy live in low- and middle-income countries (LMICs), where limited resources and stigma hinder accurate diagnosis and treatment. Clinical machine learning models have demonstrated substantial promise in supporting the diagnostic process in LMICs by aiding in preliminary screening and detection of possible epilepsy cases without relying on specialised or trained personnel. How well these models generalise to naïve regions is, however, underexplored. Here, we use a novel approach to assess the suitability and applicability of such clinical tools to aid screening and diagnosis of active convulsive epilepsy in settings beyond their original training contexts. …

The Hidden Cost Of Using Time Series Aggregation For Modeling Low-Carbon Industrial Energy Systems: An Investors’ Perspective, Markus Fleschutz

Publications

Time series aggregation (TSA) is commonly used in energy system optimization to reduce model complexity and computational expenses by selecting periods to represent the entire time series. TSA’s accuracy has traditionally been assessed by comparing the objective values between the original and TSA models (assumed error). However, evaluating TSA from an investor’s standpoint involves analyzing the performance of TSA-based energy system designs using the original time series. Therefore, we introduce the hidden error and total error, novel error metrics, to evaluate the financial implications of TSA through backtesting the TSA-based system designs using the original time series. Our analysis extends …

Blind And Low-Vision Students As Surveyors Of In/Accessibility In Technology-Mediated Formal Education, Natalie Shaheen

Faculty Publications - College of Education

K-12 institutions are slowly realizing (a) that many of the instructional technologies they use are inaccessible and (b) that technical debt oppresses blind and low-vision (BLV) students. Herein, I report the findings from a qualitative exploration of how BLV students differentiate between accessible and inaccessible technology-mediated education. The findings suggest that in/accessible technology-mediated education is an assemblage of learning, access labor, teachers, technologies, temporalities, and affectivities. I argue that to construct technology-mediated education that is equitable and accessible to BLV students K-12 institutions must do more than pay off their technical debt. I conclude with recommendations for how K-12 institutions …

Comparison Between The Partial Least Squares Method And Principal Components Using Genetic Algorithm With An Application, Hayder Osman Hussein, Rabab Abdul Rida Al-Bakri

Journal of Economics and Administrative Sciences

The problem of multicollinearity among independent variables in a regression model was addressed in this study using Partial Least Squares (PLS) and Principal Component Analysis (PCA). The influence exerted by multicollinearity can deteriorate the results of regression modeling; that is, it makes the traditional technique OLS less reliable. The research is centered on applying advanced algorithms for Partial Least Squares (SIMPL and O-PLS) as well as for PCA (NIPALS and SVD) on real-life data scenarios, as well as integrating genetic algorithm (GAs) with these algorithms to optimize predictive performance. The relative efficiency of these methods is evaluated primarily through the …
