Palpation Characteristics Of An Instrumented Virtual Cricothyroidotomy Simulator, Melih Turkseven, Trudi Di Qi, Ganesh Sankaranarayanan, Suvranu De
Engineering Faculty Articles and Research
Cricothyroidotomy (CCT) is a critical, life-saving procedure requiring the identification of key neck landmarks through palpation. Interactive virtual simulation offers a promising, cost-effective approach to CCT training with high visual realism. However, developing the palpation skills necessary for CCT requires a haptic interface with tactile sensitivity comparable to human fingers. Such interfaces are often represented by plastic partial mannequins, which require further adaptation to integrate into virtual environments. This study introduces an instrumented physical palpation interface for CCT, integrated into a virtual surgical simulator, and tested on 10 surgeons who practiced the procedure over a training period. Data on haptic …

Background/Objectives: Autism spectrum disorder (ASD) is a neurodevelopmental condition associated with behavioral and cognitive impairments. Increasing evidence also links ASD with systemic immune dysregulation, including abnormal cytokine profiles and chronic low-grade inflammation. Emerging evidence suggests that targeted dietary strategies and probiotic supplementation may modulate immune responses and gut–brain interactions in patients with ASD. This study aimed to evaluate the immunomodulatory effects of a structured anti-inflammatory diet (NeuroGutPlus) compared to multi-strain probiotics in children with ASD. NeuroGutPlus is a nutritionally complete anti-inflammatory dietary protocol that targets gut integrity, inflammation, and mitochondrial function. It includes a diet low in gluten, FODMAPs, casein, …

The study contributes to theoretical formulations, detailed system modeling, and controller tuning procedures, promoting a comprehensive understanding of their structures and performance. The strategies are investigated and compared in both the rotating ((Formula presented.)) and stationary ((Formula presented.)) reference frames, offering a broad perspective on system behavior under various operating …
Registered Nurses' Autism Knowledge And Preparedness To Care For Autistic Patients, Bronte Elisa Weissman
Registered Nurses' Autism Knowledge And Preparedness To Care For Autistic Patients, Bronte Elisa Weissman
Theses and Dissertations
Autistic individuals frequently report negative experiences during healthcare interactions and numerous provider-level barriers to accessing quality care, including stereotyping, perceived lack of autism knowledge, challenges with communication, and insufficient accommodations. Reports of healthcare providers’ experiences caring for autistic patients in the U.S. have largely come from physicians, who endorse inadequate training, resources, and practical guidelines. Although patients spend far more time with nurses than other healthcare providers, registered nurses (RNs)’ perspectives on caring for autistic patients in the U.S. are largely unknown and autism-focused trainings for nurses are minimal. In the current study, a survey was nationally disseminated to a …

Cationic Liposome Nanoparticles For Drug Delivery To The Inner Ear, Firas Al-Ashker
Master's Theses (2009 -)
Cisplatin is a widely used chemotherapy drug associated with a high incidence of hearing loss, particularly in younger patients. This ototoxicity is linked to the drug’s long-term accumulation in the cochlea, where it can persist for years following treatment. Current clinical interventions, such as sodium thiosulfate (STS), offer partial protection against hearing loss but are limited by poor drug penetration into the inner ear. The objective of this study was to develop and evaluate a targeted drug delivery platform capable of overcoming anatomical and physiological barriers to reach the cochlea more effectively. Specifically, we aimed to design cationic liposome nanoparticles …

Design And Evaluation Of An Electromagnetic Band Gap Structure For Self-Interference Reduction In Mmwave Full-Duplex Systems, Adewale Kehinde Oladeinde
Dissertations and Theses
Full-duplex (FD) wireless is a new technology that allows a device to transmit and receive at the same time and on the same frequency band. It has the potential to double the capacity and spectral efficiency of a wireless link compared to the family of conventional half-duplex wireless systems. The key challenge in implementing FD wireless communication is self-interference (SI): a node's transmitting signal generates significant interference to its receiver. Several previous studies have demonstrated the potential to reduce SI and develop FD radios; however, these studies are mostly limited to sub-6 GHz systems. Previous and on-going research explored various …
Strategies To Use Diversity, Equity, And Inclusion Programs To Increase Employee Performance And Profitability, Kecia Bailey Alexander
Strategies To Use Diversity, Equity, And Inclusion Programs To Increase Employee Performance And Profitability, Kecia Bailey Alexander
Walden Dissertations and Doctoral Studies
A lack of effective strategies for implementing diversity, equity, and inclusion (DEI) programs to increase employee performance and profitability is a concern for leaders in the education industry. This problem is significant to educational leaders because, without effective strategies for implementing DEI programs, they cannot address the gap in practice that hinders improvements in employee performance and organizational profitability. Grounded in Ajzen’s theory of planned behavior, this qualitative pragmatic inquiry identified and explored the effective strategies educational leaders used to successfully implement DEI programs to increase employee performance and profitability. Participants were six leaders from both for-profit and non-profit educational …

Low Beta Anomaly In Some European Emerging Markets, Tadeusz Winkler-Drews, Mateusz Mogilski
Journal of Banking and Financial Economics
The aim of the study was to identify the low beta anomaly and analyse the causes of its occurrence in five European emerging markets that were components of the MSCI Emerging Markets Europe index in the period 2010–2019. It was hypothesized that the determinants of the low beta anomaly in the analysed markets are factors from at least two of the three categories of variables. Using the Betting Against Beta model proposed by A. Frazzini and L. H. Pedersen (2014), we found that this phenomenon was not identified in three markets, but occurred in the remaining two markets, for which …

La Niña Effects On The Mjo Modulation Of North Pacific Atmospheric Rivers And Associated Western North American Precipitation, L. G. Fernandes, Paul C. Loikith, M. Mora
Geography Faculty Publications and Presentations
We investigate connections between the Madden‐Julian Oscillation (MJO) and North Pacific atmospheric rivers (ARs) and associated precipitation over North America during La Niña (LN) years. Overall, AR frequency is reduced over the northeastern Pacific and western North America in phases 2–5 of the MJO. However, under LN, increased AR activity appears over those regions in phases 4–6 and across the central North Pacific in Phase 3. Distinct effects of LN on the basic state and MJO contribute to the persistence of AR anomalous patterns in phases 3–6. For instance, MJO intensifies in Phase 3 under LN, favoring the coupling between …

The problem that was addressed through this study is that teachers are leaving the profession in an Arizona high school district (AHSD, a pseudonym), which might be due to a lack of administrator support. The purpose of this basic qualitative study was to explore teachers’ perceptions of reasons they chose to remain in their positions as well as administrators’ perceptions on the support they provide to encourage teacher retention at AHSD. Grounded in Bandura’s social cognitive theory, semistructured interviews were conducted with six administrators and 10 teachers from AHSD. Saldana’s pattern coding was used with the following themes emerging: Teachers …
Using Exercise To Treat Anxiety In Adult Patients With Addiction, Emmanuella N. Nnadozie
Using Exercise To Treat Anxiety In Adult Patients With Addiction, Emmanuella N. Nnadozie
Walden Dissertations and Doctoral Studies
Summary In this Doctor of Nursing Practice (DNP) project, I selected a staff education as the best intervention to improve staff knowledge in using exercise to treat anxiety disorders in adult patients at a recovery clinic for addiction. Anxiety disorders are highly prevalent among individuals undergoing substance abuse treatment, often exacerbating withdrawal symptoms and increasing relapse risks; thus, integrating the use of exercise in addition to existing standard care for anxiety treatment in individuals with substance use disorder (SUD) will lead to decreased anxiety, decreased alcohol use and drug cravings, improved quality of life and affect, increased abstinence, and improve …
Reconciling Harm Reduction Philosophy And Approaches Among Abstinence-Only Substance Abuse Treatment Professionals, Amy Rose Ashton-Williams
Reconciling Harm Reduction Philosophy And Approaches Among Abstinence-Only Substance Abuse Treatment Professionals, Amy Rose Ashton-Williams
Walden Dissertations and Doctoral Studies
Historically, substance use disorder (SUD) treatment in the United States has been firmly grounded in abstinence-only treatment approaches. Harm reduction as a treatment model has gained additional traction. With increased rates of opioid use, overdoses, and advancements in medications for SUDs, harm reduction treatment approaches are becoming more important to improve lives of people who use drugs. Little is known about how counselors who have been educated, trained, and deliver abstinence-based SUD treatment reconcile use of harm reduction into their practice. To address this gap in literature, a generic qualitative study was conducted using the social constructivism theory. A purposive …
Enhancing Social Determinants Of Health Education In Home Health Care Including Social Determinants Of Health In Assessments And Care Plans For Home Health Clinicians, Emilia Mbanwite
Walden Dissertations and Doctoral Studies
This staff education-focused doctor of nursing practice (DNP) project addressed the critical practice problem of one southern health care facility staff’s knowledge on the integration of social determinants of health (SDOH) into home health care plans. Despite SDOH screening, clinicians lacked standardized training to effectively assess and intervene on factors such as housing, transportation, and food insecurity, contributing to preventable hospitalizations, particularly in vulnerable populations. The practice-focused question addressed whether an evidence-based education module could improve home health nurses’ knowledge and application of SDOH in assessments and care plans. The project’s purpose was to develop, implement, and evaluate this training …

A Potential New Sea Surface Temperature Proxy Based On Isomeric Highly Branched Isoprenoid Lipid Biomarkers: Ez25, Simon T. Belt, Lukas Smik, Katrine Husum, Jochen Knies
School of Geography, Earth and Environmental Sciences
Two tri-unsaturated and isomeric (E/Z) highly branched isoprenoid (HBI) diatom lipid biomarkers were quantified in 228 water column samples collected from the English Channel, West Svalbard (Arctic), the Scotia Sea (Southern Ocean) and East Antarctica. We found that the relative amounts of the two HBIs correlate well with water temperatures taken at the time of sampling. Based on these findings and some other HBI data reported previously, we suggest that the proportion of the HBI E-isomer (termed EZ25) may serve as a new proxy for palaeo sea surface temperatures, including in the polar regions. Next steps will involve determination of …

Faculty, Staff and Student Publications
Objective: Emergency department (ED) sign-outs provide continuity of care for patients at shift changes. However, these periods have been associated with communication breakdowns and medical errors. We explored information factors (stage-of-the-case and the explicitness of the sign-out narrative) to determine their impact on clinicians' diagnostic accuracy and confidence.
Methods: Clinicians from 2 academic ED sites reviewed patient vignettes sign-out narratives (N=69). Using a within-subjects experiment, the explicitness of the sign-out information (i.e., broad statement about labs versus stating each test) and the patient's stage in the diagnostic process (e.g., labs pending, treatment occurring, etc.) at the time of sign-out varied. …
The Impact Of Mental Health Courts On Public Attitudes Held Toward Justice-Involved Individuals With Mental Illness, Maeve Porter
The Impact Of Mental Health Courts On Public Attitudes Held Toward Justice-Involved Individuals With Mental Illness, Maeve Porter
Student Theses
Prior research has established that mental health court programs play an important role in reducing recidivism and mental health symptoms of defendants. However, there is a lack of understanding of the stigma that justice-involved individuals may encounter upon release from mental health court into the community, and the extent to which the general public is aware of mental health court programs. The present study sought to address public perceptions regarding mental health courts, their efficacy, and their participants based on the awareness and availability of these specialized courts in two similar states (New York and New Jersey), one in which …
Development Of Turbulence Models For Prediction Of Hypersonic Flows Using Compressibility Corrections And Uncertainty Quantification With Emphasis On The Wray-Agarwal Model, Aidan Robert Murphy
Development Of Turbulence Models For Prediction Of Hypersonic Flows Using Compressibility Corrections And Uncertainty Quantification With Emphasis On The Wray-Agarwal Model, Aidan Robert Murphy
McKelvey School of Engineering Graduate Student Theses & Dissertations
Accurate prediction of high-speed compressible turbulent flows remains one of the most significant challenges in Computational Fluid Dynamics (CFD), especially in the realm of hypersonic vehicle design. These flow regimes involve significant aerodynamic heating and shock-wave boundary layer interactions (SBLI) which remain a significant challenge for the current CFD prediction capabilities. While Direct Numerical Simulation (DNS) and Large-Eddy Simulation (LES) provide high-fidelity solutions, their computational demands limit their usability, making the Reynolds-Averaged Navier-Stokes (RANS) equations an efficient alternative for many industrial aerodynamic applications. Traditional RANS techniques, while computationally efficient, often provide limited accuracy in high-speed flows due to the presence …

Theoretical Study On Electronic And Optoelectronic Properties Of Some C^N^N- And C^C^C-Chelated Iridium(Iii) Complexes For Oleds, Ayhan Üngördü
Turkish Journal of Chemistry
The electronic and optoelectronic properties of 8 C∧N∧N- and C∧C∧C-chelated Ir(III) complexes were investigated using density functional theory at the Becke-style 3-parameter Lee-Yang-Par and triple zeta plus polarization level. Based on reorganization energy calculations, complex 7 was identified as a promising ambipolar material, while complexes 1 and 2 had efficient hole transport properties. Complex 8 had low ionization potential and is therefore a strong candidate for hole transport applications. Complex 4 had high electron affinity and therefore has potential as an effective electron acceptor material. Photophysical analysis showed that all complexes had phosphorescent properties, with complexes 5 and 6 showing …
