The Perceived Impact Of Officer-Involved Domestic Violence On Law Enforcement Administrators, Victoria Smith

Walden Dissertations and Doctoral Studies

The frequency of officer-involved domestic violence (OIDV) is a serious problem in the law enforcement profession. This qualitative phenomenological study aimed to determine what measures and specific domestic violence policies are working well and what is working poorly in Florida. This study is critical because it can aid upcoming law enforcement administrators (LEAs) and current LEAs in improving the policies and measures they use in their agency to combat OIDV among their officers and recruits. Jacques’s organizational culture theory (OCT) provided a framework for this study. I used purposeful snowball sampling methods to recruit participants for this study. Six law …

Women Veterans' Use Of Gender-Specific, Online, Social Support Systems For Social Identity After Military Service, Katie M. Baillio

Walden Dissertations and Doctoral Studies

The number of women veterans serving in the military is growing. This qualitative study explored women veterans' perspectives and experiences with gender-specific online social support services, and how that contributes to their social identity after military service. A generic qualitative design was used, and data were collected through semistructured interviews for 10 women veterans who had transitioned out of the military within the last 5 years. Five themes emerged: (a) big picture: connecting with other women veterans was helpful; (b) veteran forums were used for federal or state benefits, but women used gender-specific forums for questions specific to women's issues; …

Educating Nurses On The Agency Of Healthcare Research And Quality Pressure Ulcer Prevention Program To Reduce The Rate Of Pressure Ulcers, Marie France Destaul

Walden Dissertations and Doctoral Studies

A staff development project was conducted to address the practice problem encountered in a healthcare setting. The identified gap in practice was related to a lack of knowledge of pressure ulcer injury prevention among inpatient staff. Leadership deemed it essential to address this practice problem in nursing care because the prevalence of pressure ulcer injuries in hospitalized patients was high. The following practice-focused question guided the project: For staff in an inpatient setting, will education on the Agency of Healthcare Research and Quality (AHRQ) Pressure Ulcer Prevention Program increase knowledge toward the goal of decreasing the incidence of pressure ulcers? …

A Qualitative Study On The Experiences Of Burnout Among Mental Health Practitioners Rendering Clinical Care During Covid-19, Mykiyaa Marvella Walker-Sanchez

Walden Dissertations and Doctoral Studies

Prior to the COVID-19 pandemic, between 21% and 67% of mental health practitioners in the United States experienced signs of burnout. The pandemic exacerbated these challenges, with an increased demand for mental health services. By 2022, 45% of practitioners reported burnout, and the APA’s 2023 Practitioner Pulse Survey noted that psychologists were working at the limits of their capacity, with high levels of burnout. While research on COVID-19 and burnout has expanded for physicians and nurses, less focus has been placed on mental health practitioners' experiences. The purpose of this generic qualitative study aimed to understand how mental health practitioners …

Chemistry Faculty Research & Creative Works

There is a growing interest in developing safer and more effective decontaminating agents for organophosphate-based pesticides and nerve agents. In this study, we present an effective method for the nonaqueous decontamination of these compounds using small-molecule-based decontaminating agents under ambient conditions. Our approach utilizes aryl and heteroaryl carboxaldehyde hydrazones and hydrazides to effectively hydrolyze nerve agent simulants into their nontoxic degradation products. The effectiveness of this method was evaluated using a range of nerve agent simulants, including dimethyl 4-nitrophenyl phosphate (DMNP), dimethyl methyl phosphonate (DMMP), and triphenyl phosphate (TPhP). In the presence of the heteroaryl hydrazone, the rate of hydrolysis …

Three Essays In Gamification, Innovation, And Cybersecurity, Eduard Yelagin

Electronic Theses and Dissertations Archive

This dissertation consists of three essays on Gamification, Innovation, and Cyber Security. The first essay investigates gamified stock trading. Gamification of stock trading is a novel practice by brokers to incorporate game-like features to increase clients’ engagement with trading. This study examines how the market reacts to the introduction of 142 gamification features in the mobile trading apps of 17 major U.S. brokers. I find that the gamification of trading can be viewed as a double-edged sword. It alters and worsens retail traders’ strategy by reducing their returns and increasing return volatility. However, it also reduces costs and risks for …

Teaching Bilingual Learners With Dysgraphia, Angela Gonzalez-Urbina

Masters Projects

With the push for legislation on the Dyslexia law in Michigan and elsewhere, teachers need to understand what dyslexia and dysgraphia are to support all students. An extra understanding is necessary in bilingual education and reading challenges because they use two language systems in and out of the classroom. Reading and writing are already areas that impact the working memory of the learner; adding dysgraphia to that proves to be more of a challenge. Dysgraphia can coexist with dyslexia, and individuals with dysgraphia often experience difficulties with spelling and writing speed. This project introduces dysgraphia as one of the reading …

A Brief History Of Circadian Time In The Heart, Martin E Young, Vanya Khanna, Mallory Metcalfe, Niruththaan Rameshkumar, Sarah Harington, Leo H Li, Janan Shoja Doost, Heinrich Taegtmeyer, Tami A Martino

Faculty, Staff and Student Publications

This review tracks the discovery of circadian biology in cardiovascular science, starting with early clinical observations of daily changes in heart rate, blood pressure, and cardiovascular events. These patterns suggested that time of day matters, but it was not until the past two decades that the mechanisms and knowledge translation of these rhythms were uncovered. We describe the heart's intrinsic circadian properties and importantly how this leads to regulation of cardiac gene and protein expression, neuroendocrine and vascular rhythms, metabolism, cellular electrophysiology, and cell signaling pathways. Next, we explore emerging themes, including the impact of circadian timing on ischemic injury, …

BACKGROUND: In the FUEL (Fontan Udenafil Exercise Longitudinal) trial, a positive treatment effect was identified for outcomes at the ventilatory anaerobic threshold but not for the primary outcome, oxygen consumption (Vo₂ in participants with near-normal baseline exercise performance.

METHODS: Participants were divided into subgroups by baseline predicted peak Vo₂ (< 80% versus ≥80%). Treatment effect was evaluated in those with a baseline peak Vo2 < 80% predicted and linear regression was performed to examine the interaction between subgroup and response to therapy for the primary and secondary outcomes.

RESULTS: Of the 379 participants with paired exercise data, 302 (80%) had a baseline peak Vo₂ < 80% predicted. In this subgroup, the primary outcome of peak Vo₂ improved significantly after 6 months of udenafil treatment, when compared with placebo (0.23±4.17 mL/kg per min versus -0.90±3.74 mL/kg per min; P=0.021). Secondary outcome measures, including Vo₂ at …

Emotional Development In Infancy, Claire Sanford, Samantha Gott

Florida Atlantic Undergraduate Research Journal

Developmental science has documented that infants’ emotional reactions are shaped by individual dispositions and their environment. This study investigated fear responses along with patterns of brain development in infants 6 to 10 months. Nine infant-mother dyads participated, with each infant observed twice (18 visits). An electroencephalogram (EEG) was used to analyze brain activity during resting-state and fear-eliciting conditions. Infant fear vocalizations were evaluated and coded during two conditions, i.e., an unfamiliar object (an electronic toy-spider), and an unfamiliar adult approaching. Results indicated infants’ fear vocalizations were stimuli-specific, with more fear expressed towards approaching strangers than the novel object. Findings also …

Use Of A Novel Plant Essential Oil-Based Insecticide For Insect Control In Household Gardens And Lawns, Mia Michnik, Alysa Suissa, Liah Brussolo Cremona, Annalise Wellman, Nicholas Nifakos, Alexander Spanoudis, John M. Harlin

Florida Atlantic Undergraduate Research Journal

Insecticide use has increased as population and agricultural demand for crops grows. Commercial insecticides contain active ingredients that are often harmful to humans and the environment. A viable alternative to this concern is developing and using insecticides with low toxicity and minimum risk to the environment. In this study, we sought to empirically assess the effectiveness of an insecticide based entirely on plant essential oil active ingredients, which contain complex secondary metabolites. Our results show that a concoction of several plant essential oils was effective in killing a wide range of household garden insect species and bedbugs, encompassing five orders …

Mock Battles: A Time And Place For Conflict, Benjamin Crawford

Florida Atlantic Undergraduate Research Journal

Mock battles are a category of ritual widely recognized by cultural anthropologists, and yet the term as used stands as a wide umbrella covering an incredibly disparate range of human behaviors. Ethnographers have applied the label of “mock battle” both to events incorporating actual bodily harm—most famously, the Andean Tinku—and to non-violent theatrical performances such as the Moros dances popular throughout Spain and Mexico. To better understand the particular social functions of these rituals, I distinguish between two separate but interrelated “genres” of mock battle: the Civil War type, in which communities schedule limited outbursts of cathartic physical violence; and …

From Company To Crown: The 1858 Government Of India Act In The British Press, Benjamin Cohen

Florida Atlantic Undergraduate Research Journal

In the aftermath of the Indian Mutiny and the perceived failures of the British East India Company, the British Parliament passed the 1858 Government of India Act, which liquidated the Company and placed India under direct rule by the Crown. The historiography on the Company’s end and the Raj’s beginning has not given adequate attention to the Act itself, portraying it as an uncontroversial measure used to change India’s governing body. This article addresses the controversial nature of the Act. By examining geographically and politically dispersed newspaper articles from when the Act was being considered in Parliament, this research shows …

Development Of A New Ground-Based Instrumentation Technique For Low-Resolution Exoplanet Transmission Spectroscopy, Mary Anne Limbach, Luke M. Schmidt, Ryan J. Oelkers, Darren L. Depoy

Physics & Astronomy Faculty Publications

We present a new instrumentation technique for high-precision, ground-based spectrophotometric measurements ideal for low-resolution (R ∼ 20–60) exoplanet transmission spectroscopy. This technique employs novel thin-film coating technology for wide-band, simultaneous multi-band imaging, enabling high-precision differential photometry through self-referencing and comparison stars. Theoretical calculations and on-sky results show that this method effectively reduces 96% of amplitude scintillation noise and other systematics that typically limit ground-based spectrophotometric precision for bright stars. On-sky results are demonstrated using the custom-built Exoplanet Transmission Spectroscopy Imager (ETSI), deployed at the McDonald Observatory 2.1 m telescope in 2022. For a V = 9.7 mag star, ETSI …
