Impact Of Primary Preventive Initiatives To Reduce Burnout And Compassion Fatigue In Emergency Department Nurses, Kelley Molandes

Doctor of Nursing Practice (DNP) Manuscripts

Background and significance: It is estimated that 20% of nurses leave the profession within the first year due to an onset of burnout (Henson, 2020). Prior to the pandemic of 2020, workforce projected models estimated large-scale shortages in full time employee (FTE) registered nurses as demand continued to outpace supply (Lauer, 2022). Researchers estimate projections from 2024 into the year 2032 are now skewed, as pandemic-related contributors and their effects on burnout in the nursing profession have not been thoroughly assessed (Saravanan et al., 2022). When considering the data, an underlying need for burnout prevention amongst nurse residents emerges. Interventions …

Sea Otter Behavior And Prey Composition Across Alternative Reef States In Monterey, Ca: Applying Ecological Theory To Kelp Restoration, Carter Hawkins

Master's Theses

Due to a myriad of factors, giant kelp (Macrocystis pyrifera) abundance along the California coast has decreased in select areas, leading to the formation of lower-diversity ecosystems dominated by purple sea urchins (Strongylocentrotus purpuratus), known as “urchin barrens.” While sea otters (Enhydra lutris) are keystone predators that help maintain kelp forests through predation on sea urchins, in Monterey, they avoid barren sea urchins due to their low energetic value and abundance of other habitat types, limiting their influence in these areas. From 2021-2023, sea urchin culling at Tankers Reef, a former barren site in Monterey Bay, was conducted to promote …

Vaccination With Acinetobacter Baumannii Adhesin Abp2d Provides Protection Against Catheter-Associated Urinary Tract Infection, Morgan R Timm, Kevin O Tamadonfar, Taylor M Nye, Jesús Bazán Villicaña, Jerome S Pinkner, Karen W Dodson, Ali H Ellebedy, Scott J Hultgren

2020-Current year OA Pubs

Catheter-associated urinary tract infections (CAUTIs) contribute greatly to the burden of healthcare-associated infections. Acinetobacter baumannii is a Gram-negative bacterium with high levels of antibiotic resistance that is of increasing concern as a CAUTI pathogen. A. baumannii expresses fibrinogen-binding adhesins (Abp1D and Abp2D) that mediate biofilm formation on catheters, which become coated with fibrinogen upon insertion. Here we develop a protein subunit vaccine against the Abp1D and Abp2D receptor binding domains (RBD) and show that vaccination significantly reduces bacterial titers in a female mouse model of CAUTI. We further demonstrate that immunity to Abp2D

Visio Dei, Vision Pro: Beatific Vision And Technological Singularity, John Paul Arceno

Liberty Theological Review

This paper offers a retrieval of the classical Christian theology of beatific vision. The reason behind this is the challenges posed by the progress of digital technology, including Artificial Intelligence, Virtual Reality, and robotics, which are prevalent today. This rapid progress somehow threatens the classical view of beatific vision with its version of technological singularity. Hence, the retrieval of the beatific vision, which is grounded in divine ontology, is much needed. The paper is divided into three parts: (1) Visio Dei, which discusses the doctrine of beatific vision, (2) Vision Pro, which discusses technological singularity, and (3) conclusion, which …

In this paper, we suggest a new lightweight …

Hybrid Organic–Inorganic Corrosion Inhibitors: Bridging Performance And Eco-Safety, Hasan M. Luaibi, Saja S. Al-Tweel

AUIQ Technical Engineering Science

Corrosion leads to global economic losses exceeding $2.5 trillion annually and accounts for up to 30% of infrastructure failures. Conventional corrosion inhibitors face limitations such as aquatic toxicity (LC50 <100 mg/L), moderate efficiencies (65–82%), and poor long-term durability (<500 hours). This review critically evaluates hybrid organic–inorganic corrosion inhibitors, focusing on their composition, mechanisms, performance metrics, and eco-safety. Hybrid systems comprising organic molecules integrated with inorganic matrices like sol–gel networks, nanocomposites, and layered double hydroxides (LDHs) demonstrate enhanced functionality through barrier effects, self-healing, and controlled release. These materials achieve inhibition efficiencies of 88–98.5%, outperforming conventional systems by 18–35%. Sol–gel coatings protect carbon steel at 92–98% efficiency in 3.5% NaCl, while LDHs sustain 94–97% protection over 1200–1500 hours. Nanocomposites reduce corrosion rates from 0.95 mm/year to 0.002–0.004 mm/year. Electrochemical techniques (EIS, PDP) show increased charge transfer resistance (500–2500 Ω·cm²) and coating resistance up to 10⁸ Ω·cm². Surface analysis reveals smoother films (Ra = 15–35 nm), higher contact angles (95–125°), and adhesion strengths of 12–18 MPa. Case studies report 90–96% protection in marine settings, 88–94% in acidic media, and over 92% under atmospheric conditions. Durability tests confirm >90% efficiency after 1000 hours, significantly higher than the <60% for conventional coatings. Overall, hybrid inhibitors offer a high-performance, eco-conscious alternative for corrosion control, combining efficiency, environmental safety, and scalability. Their superior metrics and adaptability position them as next-generation solutions for diverse industrial applications.

Challenges In Modelling The Impact Of Frost And Heat Stress On The Yield Of Cool-Season Annual Grain Crops, Jonathan Richetti, Victor Oscar Sadra, Di He, Brenton Leske, Pengcheng Hu, Yacob Beletse, C. Mariano Cossani, Ha Nguyen, Bangyou Zheng, David Matthews Deery, M. Fernanda Dreccer, Jeremy Whish, Julianne Lilley

Grain and Other Field Crops Research Articles

Frost and heat events at critical growth stages could cause large yield losses. These temperature extremes are increasing in frequency and intensity due to climate change in many parts of the broadacre cropping regions globally, presenting challenges to food production. For cool-season grain-growing regions, where summers are already too hot, heat and frost risks can limit adaptation options. Capturing these stresses in crop models accurately is increasingly important for evaluating the timing, severity, and yield consequences of extreme events. However, most existing process-based models were not designed to simulate short-duration temperature extremes, limiting their ability to assess climate risk and …

Illness Terminable And Interminable: A Lacanian Exploration Of Medical Assistance In Dying, Matthew Devine

Electronic Theses and Dissertations

More and more people worldwide are requesting euthanasia, physician-assisted suicide (PAS), or medical assistance in dying (MAiD). Arguments in favor of expanding access to MAiD tend to prioritize the rational, competent, autonomous subject who has the right to make decisions about their body, including their death. Some have argued that this perspective – common in biomedical and bioethical literature – tends to neglect the fact that requests for assisted dying involve a relational structure: a relationship between the subject who requests an assisted death and the Other to whom this request is addressed. After reviewing relevant psychoanalytic approaches to suicide …
