Echoes Of The Past: The Long-Lasting Effects Of Entrepreneurs' Generational Imprints On Value-Creation Models, Ileana Maldonado-Bautista, Paul Sanchez-Ruiz, Annaleena Parhankangas, Karen Watkins

Management Faculty Publications

We draw from theories of generations and imprinting to introduce an alternative conceptualization of the effects of age on entrepreneurship—namely, entrepreneurs' generational imprints. We theorize how imprinted characteristics of entrepreneurs from a conservative generation (vs. a progressive generation) are positively (negatively) associated with higher levels of financial returns and negatively (positively) associated with higher engagement in corporate social responsibility. In two studies in the Mexican context, we find that entrepreneurs from a conservative generation create more financial value than social value, while entrepreneurs from a progressive generation create more social value than financial value. We also explore the intervening …

Fostering Success: How Cross Campus Partnerships Can Improve Accessibility, Engagement, And Inclusion For Autistic Undergraduate Students, Mercedes Rutherford-Patten, Luna Nombrano Larsen

Library Scholarship

The academic library, with its long history of student support and social justice advocacy, is the perfect organization to lead the way in dismantling systemic barriers to student success. Research shows that college students who regularly use library services are more successful academically (Shea & Derry, 2022). Another vital support the library can provide is community. Inclusion and belonging are integral to the success of autistic college students: “feeling like part of a community” and “to always feel like I’m welcome [on-campus]” were ways students measured their own success in a study by the Autistic Self Advocacy Network (2020, p. …

The Effect Of Hypochlorous Acid On Cultured Osteoblast And Escherichia Coli, Cristina Flaquer Fusté

Graduate Theses/Dissertations

Hypochlorous acid (HOCl), a naturally occurring compound in neutrophils, has been used as an antimicrobial in wound treatment. Osteoblasts, bone-forming cells, within the bone tissue play a large role in bone fracture healing. Orthopedic infections are challenging to treat and highly morbid, including surgical site infection of arthroplasty procedures or infection in the setting of compound fractures. HOCl is being considered as a surgical antiseptic to decrease infections in orthopedic surgical procedures. This study therefore seeks to determine the effects of HOCl on osteoblasts and E. coli. Cultured osteoblasts were incubated with varying concentrations of HOCl to examine osteoblast …

Exploring Physics Teacher Identity: Pathways Toward Equitable Instruction Among Teachers, Clausell Mathis, Jomo Mutegi, Turhan Carroll, Maya Patel, Andrea Wooley

Teaching & Learning Faculty Publications

Physics teacher identity encompasses teachers' beliefs and views toward being a physics teacher. Physics teacher identity is influenced by teachers' perspectives on physics teaching and learning. Previous studies on teacher identity in general suggest that the construct is complex and malleable. Studies further suggest that it influences instructional methods, student engagement, and classroom environment. However, within physics education, there has yet to be an examination of how physics teacher identity influences "equitable" teaching approaches. This qualitative study sought to identify various dimensions of physics teacher identity and its implications for physics education research. We interviewed secondary and postsecondary physics teachers …

The Sky’S The Limit: Improving Satellite Imagery Data Literacy To Address Noncommunicable Diseases, M. Courtney Hughes, Elizabeth J. Folkmann

Faculty Articles, Papers, and Other Scholarship

Low-and middle-income countries experience 77% of the world’s premature deaths caused by non- communicable diseases, and their underlying health determinant data are often scarce and inaccurate. Im- proving satellite imagery data literacy worldwide is an integral step toward using the vast amount of publicly available data collected via satellites, such as air pollution, green space and light at night—all determinants of non-communicable diseases. Existing machine learning–based algorithms enable automated analysis of satel- lite imagery data, but health officials and scientists must know where to find and how to apply these algorithms to measure risk and target interventions.

Elucidating The Proteolytic Determinants Of Flavivirus Infection, Lochlain C. Corliss

All ETDs from UAB

Flaviviruses, recently renamed to orthoflaviviruses, are small, enveloped viruses with positive-sense, single-stranded RNA (ssRNA) genomes of about 11 kilobases. Upon cell entry and uncoating, the viral RNA (vRNA) is directly translated at the endoplasmic reticulum (ER) as a single polyprotein that is then processed by the viral and cellular proteases into 10 functional subunits, consisting of three structural proteins and seven nonstructural (NS) proteins. Among the NS proteins are NS2B and NS3, which form the viral protease complex. NS3 consists of a serine protease domain while NS2B is anchored to the ER and contains a cytoplasmic loop that serves as …

Stimulation And Quantification Of Dopamine-Associated Behaviors, Hunter Goffinett

All ETDs from UAB

Dopamine (DA) is a neurotransmitter involved in the regulation of essential behaviors, including motor control and reward processing. Alterations in DA levels can significantly modulate these behaviors: increased DA release is associated with heightened locomotion and enhanced preference for rewarding stimuli. Therefore, measuring behavioral changes in vivo provides critical insight into DA release and function. In this study, we quantified DA-associated behaviors by radiolytic stimulation of the Drosophila A-isoform of the transient receptor potential ankyrin type-1 A (dTRPA1(A)) channel and investigated how the human-immunodeficiency virus (HIV) and its secreted protein, the trans-activator of transcription regulatory protein (Tat), alter drug-induced behaviors. …

Optimizing Defibrillation Response: A Quality Improvement Initiative In The Cath Lab, Sara Cullis Bsn, Rn

Nursing Publications, Posters, & Presentations

This poster was presented at the 2025 Parkview Nursing Research Symposium.

Patients undergoing diagnostic or emergent procedures in the Cardiac Cath Lab are at risk of developing lethal arrhythmias, which require immediate defibrillation to prevent adverse outcomes. Currently, the use of paddles and the absence of pre-applied defibrillator pads delay response time during critical events, increasing the risk of morbidity and mortality. Additionally, there is a liability when staff assume which patients are “high risk” versus “diagnostic,” as even seemingly low-risk cases can rapidly deteriorate without warning. This quality improvement initiative aims to address this gap by ensuring defibrillator pads …
