Strong Ultrafast Demagnetization Due To The Intraband Transitions, G. P. Zhang, Mitsuko Murakami

Symposium Projects

Demagnetization in ferromagnetic transition metals driven by a femtosecond laser pulse is a fundamental problem in solid state physics, and its understanding is essential to the development of spintronic devices. Ab initio calculation of time-dependent magnetic moment in the velocity gauge so far has not been successful in reproducing the large amount of demagnetization observed in experiments. In this work, we propose a method to incorporate intraband transitions within the velocity gauge through a convective derivative in the crystal momentum space. Our results for transition-element bulk crystals (bcc Fe, hcp Co and fcc Ni) based on the time-dependent quantum Liouville …

Improving Maternal And Infant Health: A Quality Improvement Initiative To Recognize Postpartum Depression In The Neonatal Intensive Care Unit., Amy Barry

Doctor of Nursing Practice Papers

BACKGROUND: While postpartum depression (PPD) is a significant problem in the postpartum population, emerging literature suggests that PPD is disproportionately concentrated and underdiagnosed among mothers of infants admitted to the neonatal intensive care unit (NICU).

PURPOSE: The purpose of this project was to institute a PPD screening protocol within a Level III NICU to identify mothers exhibiting signs of distress and initiate social work referrals.

METHODS: A quality improvement project implemented utilizing the Plan-Do-Study-Act (PDSA) framework and a pre-and-posttest design.

INTERVENTION: Staff education regarding PPD symptoms and the project’s protocol occurred via electronic means. Mothers of NICU infants who remained …

Identification Of Structural Brain Alterations In Adolescents With Depressive Symptomatology, J. Bashford‑Largo, R. James R. Blair, Karina S. Blair, Matthew Dobbertin, Ahria Dominguez, Melissa Hatch, Sahil Bajaj

Center for Brain, Biology, and Behavior: Faculty Publications

Introduction: Depressive symptoms can emerge as early as childhood and may lead to adverse situations in adulthood. Studies have examined structural brain alternations in individuals with depressive symptoms, but findings remain inconclusive. Furthermore, previous studies have focused on adults or used a categorical approach to assess depression. The current study looks to identify grey matter volumes (GMV) that predict depressive symptomatology across a clinically concerning sample of adolescents.

Methods: Structural MRI data were collected from 338 clinically concerning adolescents (mean age = 15.30 SD=2.07; mean IQ = 101.01 SD=12.43; 132 F). Depression symptoms were indexed via the Mood …

Building Teachers’ Capacity To Implement Equitable Family, School, And Community Partnerships Through School Psychologists’ Consultation: The Partnership Capacity Building Consultation Model And Case Study, Bryanna S. Fatigate

Electronic Theses and Dissertations

The urgency to prioritize equity-driven policies is amplified by the disproportionate education and health outcomes that emerged during the COVID-19 pandemic. Eradicating inequity demands the prioritization of robust family, school, and community partnerships (FSCP). For decades, research has highlighted the benefits of FSCP, which may include improvements in student academic achievement, behavior, ratings of school climate, and attendance; furthermore, FSCP is associated with higher guardian involvement, mentor opportunities, career development, and a reduced need for more intensive services such as special education (Adelman & Taylor, 2015; Anderson- Butcher & Anderson, 2018; Constantino, 2016). To reap the benefits of such partnerships, …

Activation Of The Renin–Angiotensin–Aldosterone System Is Attenuated In Hypertensive Compared With Normotensive Pregnancy, Robin C. Shoemaker, Marko Poglitsch, Hong Huang, Katherine Vignes, Aarthi Srinivasan, Cynthia Cockerham-Morris, Aric Schadler, John Anthony Bauer, John O'Brien

UK CARES Faculty Publications

Hypertension during pregnancy increases the risk of adverse maternal and fetal outcomes, but the mechanisms of pregnancy hypertension are not precisely understood. Elevated plasma renin activity and aldosterone concentrations play an important role in the normal physiologic adaptation to pregnancy. These effectors are reduced in patients with pregnancy hypertension, creating an opportunity to define the features of the renin–angiotensin–aldosterone system (RAAS) that are characteristic of this disorder. In the current study, we used a novel LC-MS/MS-based methodology to develop comprehensive profiles of RAAS peptides and effectors over gestation in a cohort of 74 pregnant women followed prospectively for the development …

Al Sabbakh, Omotayo A. Segun-Omosehin, Natalie E. Bourdakos, Maya Nasser, Reem H. Matar, Christian Than, Omar A. Danoun, Andrew Johnson

Neurology Articles

Deep brain stimulation (DBS) is extensively used to treat motor and non-motor symptoms in Parkinson's disease (PD). The aim of this study was to investigate the difference between subthalamic (STN) and globus pallidus internus (GPi) DBS on mood and quality of life with reference to minimal clinically important differences (MCID). A systematic literature search for articles published until November 2022 yielded 14 studies meeting the eligibility criteria, with a total of 1,088 patients undergoing STN (n=571) or GPi (n=517) stimulation. Baseline patient and clinical characteristics were comparable between the two groups. Results showed that GPi stimulation demonstrated a greater reduction …

Inequities Gone Or Enduring? Evaluating The Effects Of A School-Based Antistigma Intervention On Race/Ethnic And Gender Intersectional Disparities In Mental Illness Stigma, Melissa J. Dupont-Reyes, Alice P. Villatoro, Jared Datzman, Jo C. Phelan

Public Health

While significant mental illness stigma disparities across race/ethnicity and gender exist, little is known about the efficacy of antistigma interventions in reducing these intersectional disparities. We examine the 2-year effects of school-based antistigma interventions on race/ethnic and gender intersectional stigma disparities among adolescents. An ethnically and socioeconomically diverse sixth-grade sample (N = 302) self-completed surveys assessing stigma before randomly receiving an antistigma curriculum and/or contact intervention versus no intervention. Surveys were also self-completed 2-year postintervention. Stigma measures assessed general mental illness knowledge/attitudes, awareness/action, and social distance. Stigma toward peers with specific mental illnesses was examined using vignettes—two adolescent characters were …

Modeling Biphasic, Non-Sigmoidal Dose-Response Relationships: Comparison Of Brain- Cousens And Cedergreen Models For A Biochemical Dataset, Venkat D. Abbaraju, Tamaraty L. Robinson, Brian P. Weiser

Rowan-Virtua School of Osteopathic Medicine Departmental Research

Biphasic, non-sigmoidal dose-response relationships are frequently observed in biochemistry and pharmacology, but they are not always analyzed with appropriate statistical methods. Here, we examine curve fitting methods for “hormetic” dose-response relationships where low and high doses of an effector produce opposite responses. We provide the full dataset used for modeling, and we provide the code for analyzing the dataset in SAS using two established mathematical models of hormesis, the Brain-Cousens model and the Cedergreen model. We show how to obtain and interpret curve parameters such as the ED50 that arise from modeling, and we discuss how curve parameters might change …

Terrain And Adversary-Aware Autonomous Robot Navigation, Aniekan Ufot Inyang

Electronic Theses and Dissertations

In autonomous robot navigation, the robot is able to understand the environment around it for intelligent navigation. From its world model of this environment, it generates a global plan for navigation from a position to a goal based on different factors. This research aims to implement autonomous robot navigation by learning terrain affordances: traversability (moving quickly) and concealment (staying hidden from an adversary) using the Preference-based Inverse Reward Learning (PbIRL) methodology. The PbIRL methodology reduces the barrier of generating initial demonstration data to learn the terrain affordances by using a human expert’s preferences to learn individual weights over the terrain …

The Treasury Of Stories: Policy Narratives Of Anti-Illicit Finance, Paul Christopher Kemp

Electronic Theses and Dissertations

This dissertation explores how the US government identifies and responds to the problem of illicit finance, specifically, why the US Treasury utilizes certain approaches over others. I employ a comparative case study of three relatively recent, non-traditional approaches in the Treasury’s anti-illicit finance repertoire: targeted financial sanctions (a case of strong policy action), anti-money laundering in real estate (a case of tentative policy action), and the proposed demonetization of high denomination notes (a case of policy inaction). While considering a wide range of plausible explanations for this variation in policy action, I argue that the Treasury’s decision to either …

Not Too Scared To Enter: Understanding The Uppsala Model’S Complexity As Sme Decision Makers Enter High-Risk Countries, Andrew Kindfuller

Electronic Theses and Dissertations

Johanson and Vahlne’s Uppsala internationalization model is a framework for understanding sequential internationalization, experiential learning, and the commitment decision processes designed to answer the question: “Why and how do firms internationalize?” Each potential market is distinctive due to dissimilar languages, cultures, religions, ethics, political systems, laws, business norms, etc. – all these perceptual differences, which can potentially block the free flow of information between markets, are called “psychic distance.” By completing 34 detailed, semi-structured interviews with executives who have recently made significant financial or resource commitments to enter 28 different challenging countries, this is the first study to focus with …

Generalized Double Statistical Convergence Sequences On Ideals In Neutrosophic Normed Spaces, Jeyaraman M., Iswariya S., Pandiselvi R.

Neutrosophic Systems with Applications

In this present research, having view in the Neutrosophic norm (u, v, w), which we presented I2-lacunary statistical convergence and I2-lacunary convergence strongly, looked into interactions between them, and made a few findings regarding the respective categories. At least went further to look at how both of such case approaches relate to I2-statistical convergence within the relevant Neutrosophic normed space.

Topology Optimization For Artificial Neural Networks, Justin Mills

Masters Theses & Specialist Projects

This thesis examines the feasibility of implementing two simple optimization methods, namely the Weights Power method (Hagiwara, 1994) and the Tabu Search method (Gupta & Raza, 2020), within an existing framework. The study centers around the generation of artificial neural networks using these methods, assessing their performance in terms of both accuracy and the capacity to reduce components within the Artificial Neural Network’s (ANN) topology.

The evaluation is conducted on three classification datasets: Air Quality (Shahane, 2021), Diabetes (Soni, 2021), and MNIST (Deng, 2012). The main performance metric used is accuracy, which measures the network's predictive capability for the classification …

Characterization Of Legionella Pneumophila Effector Proteins, Lneb And Mava, Kayode Adeyemi

Masters Theses & Specialist Projects

The crucial virulence factor of accidental human pathogen Legionella pneumophila during the course of Legionnaire disease is the over 300 effector proteins secreted from its Dot/Icm secretion system. Eukaryotic host cells usually elicit an arsenal of immune responses against invading L. pneumophila. Nonetheless, the bacteria unexpectedly subvert these defense mechanisms to survive and proliferate unhindered in the host. Although some effector proteins have been proposed to play a significant role in this host-pathogen interaction, many still need to be characterized. The LneB and MavA proteins are examples of those effectors that need characterization. Thus, this study aimed to investigate the …

Mammalian & Avian Community Response To African Elephant (Loxodonta Africana) Habitat Modification In Southeastern Kenya, Dakota Vaccaro

Masters Theses & Specialist Projects

African elephants (Loxodonta africana) play a significant role in the modification of their habitat, foremost by decreasing woody vegetation cover and density and in some parts of Africa high elephant densities damage small sanctuaries and preserves. For wildlife that depend on forested patches, this increased modification could lead to displacement and/or decreases in abundance. If suitable habitat is not available elsewhere, elephants and other wildlife may move closer to humans in search of resources, which can result in increased human-wildlife conflict. Evaluating this impact was one of the goals of the Elephants and Sustainable Agriculture in Kenya (ESAK) …

New Insights Into The Tectonic Framework & Geologic Features Of The Bengal Basin, Bangladesh, Shahriar Bin Shahid

Masters Theses & Specialist Projects

In this research, high-resolution SRTM-based NASA Digital Elevation Models (DEM) data and published literature have used to gain new insights regarding South-east Asian surficial geology, fluvial geomorphology, and tectonics, focusing on the Bengal Basin. Seismic databased discovery of shallow, down-warping and >30 km thick Indian crust challenges prior knowledge of crustal origin, which was thought to be oceanic rather than continental in origin due to high-angle subduction. Furthermore, the collapse of the Indian passive margin beneath the Shillong Plateau may have formed a 20 km thick Surma Basin on top and has led to substantial earthquake risks. To update the …

Teacher Perceptions Of Advanced Ability English Language Learners (Ell), Dena Redmond

Masters Theses & Specialist Projects

This study explored teacher perceptions of English language learners and giftedness. High school content teachers participated in an interview identifying behaviors that indicate advanced abilities from a series of three vignettes about English language learners.

The themes were behaviors that teachers perceived as demonstrating potential or demonstrating limited potential for advanced learning in English language learners.

Investigating Visuospatial Working Memory For Facial Emotion And Identity, Brianna Lowe

Masters Theses & Specialist Projects

The central executive plays a key role in the encoding of visual stimuli in working memory, including the memory for faces in a social context. Faces often contain important details about the identity of social targets as well as the emotion that these targets are expressing. Encoding accuracy requires that we have resources to consider and organize facial features into a holistic representation of a target. Of course, emotion recognition accuracy may be critical to encoding success. The cognitive demand on the participant when evaluating facial stimuli impacts emotion recognition accuracy and therefore the encoding of facial features and emotion …

Measures were identified that educators indicated most effective for identifying gifted and talented students as well as the measures that educators felt were less effective in identification. Educators across one school district were given the opportunity to complete a survey and/or an interview in this mixed method study. Representatives from all grade and school levels have been represented in the data. This research study revealed themes related to bias in nomination, understanding gifted characteristics, choosing …

College Sexual Assault, Career Adaptability, And Grit: A Moderation Analysis, Patricia Danielle Sparks

Dissertations

Sexual assault rates are a rising concern, particularly on college campuses. The impacts of being a victim of sexual assault were well documented in the research and spread from academic decline to negative mental health outcomes to career path derailment. Career construction theory suggested a critical developmental time period for young adults where pieces of their environment, past experiences, and personal characteristics informed their career decisions. Career adaptability is a foundational piece of career construction theory that consists of psychosocial, internal resources developmentally related to how a person learns and advances in their career goals. Grit was identified in the …

Historical Narrative In The Music Of Sid Meier’S Civilization Vi, Alec Larner

Electronic Theses and Dissertations

Sid Meier’s Civilization VI is a 2016 strategy video game in which the player leads a historical civilization from 4000 BC to the present. The Civilization series is the subject of much scholarly writing, especially its representation of history and non- Western cultures. My work builds on Karen Cook’s research (2014) on the technological progress and American hegemonic identity signaled by Civilization IV’s soundtrack. I argue that the music in Civilization VI contributes to a Eurocentric teleological progress narrative of history inherent in the structure of the game: the idea that history is a story of inevitable and positive …

Risky Behavior As Motivated Emotion Regulation: A Mixed-Method Approach, Lyneé A. Herrera

Electronic Theses and Dissertations

Engaging in risky health behaviors is a ubiquitous human experience that often marks developmental progression from adolescence into adulthood. While much previous research has framed risky behaviors in terms of negative legal, social, and public health consequences, less empirical work has been done on potential benefits of their engagement. A growing body of research has identified emotion regulation deficits as a significant driver of risky behavior engagement, suggesting that these behaviors may offer perceived emotional benefits when other regulation strategies are less accessible. Previous research has shown that emotional outcomes can be influenced by the regulation strategies one chooses to …
