Vibrato In The Singing Voice: A Survey Of Vibrato Practices In The Studio For Teachers And Coaches, Anna Alyce Tarver

Electronic Theses and Dissertations Archive

Historically variable in its terminology, “vibrato” was not used until the nineteenth century. Coaches and teachers recognize it as a signature of healthy, expressive singing, except in some stylistically appropriate contexts. However, it continues to raise questions. Little data has been reported on vibrato outside of general characteristics. Only a few sources exist examining the knowledge and skillset of teachers of singing. This survey aimed to gain information on what instructors and coaches are told about vibrato in comparison to what they experience in the voice studio. An anonymous mixed-method survey was distributed to 201 professional voice teachers and coaches; …

A Scalable Cybersecurity Model For Academic Makerspaces, William Faircloth

Cybersecurity Undergraduate Research Showcase

Academic makerspaces have become integral hubs of innovation on university campuses, providing students with access to industrial-grade operational technology (OT) such as 3D printers and CNC machines. However, the security posture for these spaces has overwhelmingly focused on physical safety, creating a significant cybersecurity gap. This oversight leaves networked OT vulnerable to cyberattacks, which threaten student intellectual property, expensive equipment, and the integrity of the broader institutional network. This research addresses this critical vulnerability by developing and implementing a secure and scalable cybersecurity model at the Old Dominion University Computer Science Makerspace, founded on two core principles: robust network segmentation …

Staff Education To Acute Care Nursing Staff On Physical Medicine And Rehabilitation, Melissa Marie Emeott

Walden Dissertations and Doctoral Studies

For this Doctor of Nursing Practice project in physical medicine and rehabilitation (PM&R), the focus was on enhancing education for acute care nurses about the benefits of inpatient rehabilitation for appropriate patients. The practice problem was the underutilization of inpatient rehabilitation despite its proven benefits in improving patient outcomes and reducing readmissions. With this project, I aimed to educate nurses on identifying suitable candidates for inpatient rehabilitation, thereby improving patient care transitions and outcomes. The practice-focused question revolved around assessing the effectiveness of educational interventions in increasing nurse knowledge and referral rates to inpatient rehab.

Management Of Stenotrophomonas Mediastinitis After Heart Transplantation For Persistent Driveline Infection: A Case Report, James Lee West, Charles W. Hoopes, Jeremey Walker, Anoma Nellore, Erik J. Orozco-Hernandez

Department of Surgery Faculty Papers

We report a 62-year-old male who had a Heartware left ventricular assist device (LVAD) implantation and subsequently developed a persistent driveline infection, culminating in an abscess along the driveline site despite 18 months of antibiotic treatment. His situation was further complicated post-transplant by the onset of mediastinitis, linked to a previously undervalued Stenotrophomonas maltophilia infection. This report highlights the potential risks of heart transplantation in patients with unresolved LVAD driveline infections, particularly mediastinitis. The presence of existing driveline infections, combined with the immunosuppressed status of patients, necessitates aggressive surgical measures. Our treatment approach, involving multiple mediastinal washouts, omental flap use, …

The Efficacy Of Topical Paromomycin-Gentamicin Versus Topical Paromomycin Alone In The Treatment Of Cutaneous Leishmaniasis: A Meta-Analysis Of Randomized Controlled Trials, Tareq Alshaikh, Mohammed Jihad, Awwad Jomaa

Sultan Qaboos University Medical Journal

Cutaneous leishmaniasis (CL) is the most common protozoal skin infection worldwide. Multiple treatments for CL have been developed to address issues related to resistance, availability, and safety. Topical treatments have shown promise by reducing unnecessary systemic exposure and providing a viable local therapeutic option. A systematic review and meta-analysis were conducted of all literature published before 28 February 2025 through PubMed/MEDLINE, the Cochrane Library, and EBSCO, comparing topical paromomycin–gentamicin (PG) with topical paromomycin alone (PR). Two studies involving a total of 774 patients were included. Relative risks (RRs) from both studies were pooled using a fixed-effect meta-analysis. The meta-analysis showed …

Synthesis And Characterization Of Highly Stable Fisetin Encapsulated In Lecithin-Chitosan-Savie Nanoparticles, Hart Monyatovsky, Travis Anderson, Jay Nadeau

Physics Faculty Publications and Presentations

Senolytic drugs, of the class of polyphenolic flavonoids, have attracted attention for a wide variety of medical applications for which they may be delivered topically, orally, and/or intravenously. However, due to their hydrophobicity and sensitivity to light and oxygen, they have been proven difficult to package and deliver. Here we report a synthesis method for encapsulated fisetin using lecithin-chitosan ionic gelation with a recently reported surfactant that is an alternative to polyethylene glycol (PEG)-containing compounds. Called “Savie” for a contraction of its components, sarcosine-Vitamin E, this surfactant allows for production of sub-100 nm nanoparticles that are bench stable for at …

Vitamin D Is Glucoprotective In Aging Males But Not Females, Olivia Z B Ginnard, Maria Morales, Ji Youn Youn, Yong Xu, Stephanie R Sisley

Faculty, Staff and Students Publications

Vitamin D supplementation is linked to many beneficial health outcomes in the geriatric population, such as decreased mortality, epigenetic aging, and fracture risk. Conversely, type 2 diabetes is strongly linked to vitamin D deficiency in older adults. However, there is a discrepancy between clinical trials in adults on the efficacy of vitamin D treatment in prediabetes and diabetes. In addition, human data indicates there may be sexual dimorphism in the effect of vitamin D deficiency on dysglycemia that is more pronounced in men. These incongruities may be due to our limited understanding of the underlying mechanisms of vitamin D in …

Validation Of A Two-Item Short Form Of The Perceived Health Competence Scale, Devika Nair, Jacquelyn S Pennings, Hayden B Bosworth, Kenneth E Freedland, Sunil Kripalani, Elisa J Gordon, Gurjeet S Birdee, Justin M Bachmann

2020-Current year OA Pubs

BACKGROUND: Perceived health competence is a construct encompassing individuals’ confidence in managing their health and health-related behaviors. The 8-item Perceived Health Competence Scale (PHCS-8), developed to measure this construct, has established psychometric properties including test-retest reliability and predictive validity for health behaviors and clinical outcomes. We aimed to validate the 2-item Perceived Health Competence Scale (PHCS-2), an abbreviated version of the PHCS-8, for use in clinical and research settings where respondent burden is a primary concern. METHODOLOGY: We conducted a psychometric validation study using pooled data from 482 participants across two cohort studies conducted in an integrative medicine clinic. Participants …

Spatially Mapped Statewide Estimated Potential Evapotranspiration Using An Efficient Surface Interpolation Method: A Case Study Of South Carolina, Sudhanshu S. Panda, Devendra M. Amatya, Ka Kit Liu, Augustine Muwamba, Timothy J. Callahan

Journal of South Carolina Water Resources

Potential evapotranspiration (PET) exhibits substantial spatial and temporal variability across large landscapes, necessitating site-specific estimation for accurate environmental and water resource assessments. However, obtaining PET or ET data for specific locations across an entire state remains challenging due to the limited number of weather stations and associated environmental datasets. This study aimed to develop an automated geospatial modeling framework to map PET distribution across South Carolina, USA, using PET estimated by the temperature-based Hargreaves–Samani (H–S) method with daily weather data from 59 NOAA stations. Because the accuracy of spatial interpolation depends on both the target variable and the desired spatial …

Assessing Aerobic And Anaerobic Thresholds With Emphasis On Isocapnic Buffering In Endurance Runners, Yahya Mushaflar Fathi, Seyed Houtan Shahidi Dr., Prof. Dr. Mohamed Twfeq Othman Alhusaen Aga

International Journal of Exercise Science

International Journal of Exercise Science 18(5): 1381-1392, 2025. https://doi.org/10.70252/IYED1370 Accurate determination of metabolic thresholds is essential for designing effective endurance training. This study aimed to apply a multi-visit Step–Ramp–Step (SRS) protocol to identify aerobic (VT1) and anaerobic (VT2/RCP) thresholds in trained endurance runners, with a particular focus on delineating the isocapnic buffering region—the ventilatory phase between VT1 and VT2 where carbon dioxide (PetCO₂) remains stable despite rising ventilation. Twelve trained male runners (mean age: 27.1 ± 1.9 years; VO₂max: 60.5 ± 2.1 ml·kg⁻¹·min⁻¹) completed the SRS protocol across separate lab visits. Each session included a 4-minute moderate-intensity phase, a progressive …

Pow, Bam, Snikt: Using Superheroes To Teach Mental Health, Christopher Dabbs

Journal of Thematic Instruction

Undergraduate psychopathology (abnormal psychology) courses traditionally emphasize case vignettes of individuals with psychiatric disorders to illustrate etiology, nosology, and treatment. While pedagogically useful, these depictions can inadvertently provoke distress in students, potentially impeding engagement and learning. To address this dilemma while continuing to center the same learning outcomes, I formulated a course structure which embedded some course topics in superhero-related material with the express intent to create psychological distance between potentially distressing topics and the learners themselves. This commentary provides background for the course, evidenced-based rationale for specific pedagogical choices alongside topical material recommendations, and ends with personal reflections.

From The Stage To The Classroom: Reflections On A Psychology Of Musical Theater Class, Jill M. Swirsky

Journal of Thematic Instruction

Thematic instruction, which uses a central popular culture theme to bridge theoretical concepts and lived experience, is a powerful tool for engaging students in complex subject matter. This paper explores the design, structure, and outcomes of a Psychology of Musical Theater course that uses popular musicals as a lens for examining key psychological theories and themes. Utilizing a hybrid course design, students explored psychological themes in musicals (e.g., racism in Hairspray) through reflective writing, small and large group discussion, and a final project. Anecdotal evidence suggests that this approach enhanced engagement and promoted deeper learning, as students reported personal growth, …

From Chest Pain To Recovery: A Rare Case Of Anomalous Origin Of The Circumflex Artery From The Pulmonary Artery In A Child And The Role Of Timely Surgical Intervention, A.V. Kauk, Serezha Manukian, A.N. Arkhipov, A.V. Voitov, I.A. Soynov

Journal of the Saudi Heart Association

This report highlights the diagnostic challenges and successful surgical management in a symptomatic pediatric case with anomalous origin of the circumflex artery from the pulmonary artery. A 4-year-old boy presented emergently with dyspnea and substernal pain. Coronary angiography identified the circumflex artery originating anomalously from the right pulmonary artery. Emergency surgical reimplantation to the aorta was performed, with subsequent normalization of cardiac function (EF 67% at 3-month follow-up). Although exceptionally rare, anomalous origin of the circumflex artery from the pulmonary artery requires high clinical suspicion in pediatric patients with ischemic symptoms. Early anatomical correction yields excellent outcomes, as demonstrated in …

Direct Arylation Of 1,10-Phenanthroline Using An Organomagnesium Reagent, Nathanael A. Hirscher, Julian B. O. Van Esselstine, Bryan C. Yapo, Nadia Asif Masood, Erika L. Vandooijeweert

Department of Chemistry and Biochemistry Faculty Scholarship and Creative Works

Substituted derivatives of 1,10-phenanthroline are important ligands in inorganic chemistry. Such ligands are often synthesized by nucleophilic addition of aryl- or alkyllithium reagents to the carbon positions adjacent to the phenanthroline nitrogens. The typical reaction sequence (organolithium addition, protonolysis, oxidation, and rearomatization) has been widely used and seldom improved. We sought to replace lithium-based reagents with safer reagents based on magnesium (i.e., Grignards). The effective use of an arylmagnesium reagent in the production of a phenanthroline ligand derivative is now disclosed. Additionally, our newly reported method avoids the use of a heterogeneous oxidant (MnO2) which the traditional method employed in …

Pauline Style And A Biblical Theology, Andrew Whitney Perkins

Masters Theses

Advances in biblical linguistics, especially in the Greek of the New Testament, have provided a means for a better understanding of the text of Scripture. Advances in Greek lexicography, syntax, verbal aspect, discourse analysis, exegetical and hermeneutical methods, and the historical background behind the gospels and letters of the New Testament have greatly increased interpreters’ ability to determine what the text meant from both the writers and to the recipients of those documents. However, Christian theology, especially Systematic Theology, has remained mostly static, unaffected by these advances, and by a more accurate understanding of the biblical text. This thesis affirms …

Research Review: "Experiences Of Women And Minoritized Us Military Veteran Business Owners: Descriptive Evidence On "Vetrepreneur" Survival And Growth, Institute For Veterans And Military Families At Syracuse University

Institute for Veterans and Military Families

This research examines the survival and growth of U.S. veteran-owned businesses, focusing on gender and race disparities. Using longitudinal microdata from 1976–2019, the study reveals that veteran-owned firms exhibit higher survival rates, greater revenues, and strong payroll performance compared to nonveteran businesses, though they experience lower employment growth. Women veterans show notable resilience, suggesting military experience helps mitigate gender gaps in entrepreneurship. Findings highlight the need for targeted policies, such as improved access to capital and workforce planning, to support scaling among women and minority veteran entrepreneurs. The study provides critical insights for policymakers and future research on vetrepreneurship.

Cmsi Note 17: Replacement Removed: Vadm/General Wang Houbin—Naval Star Turned Rocket Force Commander’S Terminal Trajectory, Andrew S. Erickson, Christopher H. Sharman

CMSI Notes

Key Takeaways:

• On 17 October, China’s Ministry of National Defense announced that General (former Vice Admiral) Wang Houbin (王厚斌), Commander of the PLA Rocket Force (PLARF), was among nine senior officers expelled for “serious violations of Party discipline.”

• A career naval aviator and seasoned PLA Navy (PLAN) staff officer, Wang rose rapidly—promoted to General (3-star) in 2023 and appointed PLA Rocket Forces (PLARF) Commander to replace disgraced General Li Yuchao.

• The official reason for Wang’s downfall—“serious financial crimes involving exceptionally large sums”—echoes a familiar corruption narrative that seldom tells the full story.

• Alternative explanations point to …

Come, Heavy Sleep: Motive And Metaphor In Britten’S Nocturnal, Opus 70, Stephen Goss

Soundboard Scholar

"The prevailing melancholy [of Britten’s Nocturnal] is as natural to the guitar’s sonorities as it is appropriate in a tribute to John Dowland."

—Peter Evans, The Music of Benjamin Britten.

Such summary remarks characterise what little has been written about Britten’s Nocturnal outside the guitar world. The reader’s reaction might be one of passive agreement or mild irritation, but there is rarely dialogue because discourse is limited: Nocturnal after John Dowland is often passed over by Britten scholars with scant discussion or no mention at all. In fact, little has been added to Evans’ reliable commentary, written only three …
