Implementing A Fast-Track Pathway For Low Acuity Patients To Reduce Patient Length Of Stay In The Emergency Department, Dawnyel Donaldson

All Doctor of Nursing Practice (DNP) Scholarly Projects

Problem: Overcrowding and prolonged wait times in emergency departments (ED) negatively affect patient safety, outcomes, and satisfaction. Hospital A, a Level 1 trauma center with over 52,000 annual ED visits, consistently exceeded the national ED length of stay (EDLOS) benchmark of 6 hours, averaging 6.7 hours, with left without being seen (LWBS) rates at 2.89%, surpassing the 2% target. Low-acuity Emergency Severity Index (ESI) level 4 and 5 patients contributed to congestion due to inefficient triage processes and lack of alternative care pathways, delaying timely access to care.

Aim of the Project: The project aimed to implement an evidence-based fast-track …

Integrating Kangaroo Care Into Cesarean Delivery Practices: A Pathway To Enhanced Health Outcomes, Julia Swords

All Doctor of Nursing Practice (DNP) Scholarly Projects

Problem: Cesarean deliveries often interrupt early mother-infant bonding, delaying the initiation of breastfeeding and limiting opportunities for skin-to-skin contact. Despite national guidelines promoting immediate postpartum contact, cesarean-born infants receive kangaroo care (KC) at significantly lower rates than those born vaginally. Prior to this project, only 2% of cesarean births at the project site received KC, highlighting a significant gap in care delivery.

Aim of the Project: The aim was to evaluate the feasibility and impact of implementing kangaroo care during cesarean deliveries in a community hospital to improve neonatal outcomes and adherence to evidence-based postpartum practices.

Review of the Evidence: …

Returning To Nature: A Virtue-Based Approach To Urban Sustainability, Liam A. L. Cormack

Cities and the Environment (CATE)

This paper advocates for a pragmatic and virtue-ethics-based approach to urban sustainability initiatives that prioritizes the consideration of moral responsibility. Looking at literature on rewilding, this paper argues that the principle of ecophronesis, and the larger discipline of ecopracticology, offers a compelling framework for integrating diverse opinions on the future of conservation from different disciplines and ecological stakeholders. Ultimately, an ecophronetic approach to urban sustainability initiatives facilitates a sense of conceptual rewilding that disregards the nature-culture dualism paradigm limiting Western environmental thought and may help address the perceived alienation from nature characterized by nature-deficit disorder.

Varied Legal Parameters Shape Fiduciaries’ Ability To Act On Climate Risk, Cynthia Hanawalt, Andy Fitch

Sabin Center for Climate Change Law

Commentators who advocate either for or against corporate and asset managers addressing climate risks often refer to “fiduciary duty” as justification for their claims. Yet no field of corporate or asset management actually imposes one standalone fiduciary duty. Nor do any two business-law fields impose the same fiduciary regime. Instead, these fields adopt differing arrays of fiduciary duties to address various types of relationships, comprising a different blend of affirmative obligations and/or prohibitions, assessed with different degrees of strictness by enforcers and courts. As a result, overgeneralizations about fiduciaries’ duty in all business-law contexts tend to further obscure what a …

Longitudinal Surveillance Of Aedes Aegypti (Diptera: Culicidae) In Urban Coastal Kenya: Population Dynamics, Blood Feeding Frequency And Dengue Virus Infection Rates, Josephine Osalla, Louis Clement Gouagna, Gilbert Rotich, Maureen Nzilani, Penina Safari, Kennedy Senagi, Francis Mutuku, Baldwyn Torto, David P. Tchouassi

All Peer-Reviewed Publications

The coastal region of Kenya has emerged as a focal point for urban dengue virus transmission driven by Aedes aegypti as the primary vector. To gain a deeper understanding of the epidemiological situation, we carried out a year-long longitudinal study (December 2021- November 2022) of the population dynamics of A. aegypti through weekly mosquito surveys using ovitrap and CO2-baited Biogents (BG) mosquito traps in Ukunda, an urban township in the coastal region. Aedes eggs laid in ovitraps were exclusively A. aegypti with 80.8% mean hatch rate. A total of 35,109 adult A. aegypti were captured, with twice as many females …

The Rising Returns To R&D: Ideas Are Not Getting Harder To Find, Yoshiki Ando, James Bessen, Xiupeng Wang

Research Collection School Of Economics

R&D has grown robustly, yet aggregate productivity growth has stagnated. Is this because “ideas are getting harder to find”? Using microdata from the US Census Bureau this paper estimates R&D effectiveness in the manufacturing sector from 1976 to 2018. We find that the marginal effect of R&D on output and the gross marginal returns to R&D have risen sharply. But rivals’ R&D has also gotten more effective, raising expected obsolescence. But firm productivity growth rises with growth in the R&D stock. Higher obsolescence slows the accumulation of R&D capital, reducing the contribution to productivity growth and shortening innovation lives.

Juvenile White Sharks In Monterey Bay: Effects Of Thermal Habitat Patchiness On Local Densities Of A Novel Range Shifting Predator, Kelsey H. Montalto

Capstone Projects and Master's Theses

Climate change has shifted species' distributional ranges in many marine and terrestrial systems. For marine species, those shifts in ranges associated with ocean warming are often poleward or into deeper waters. Juvenile white sharks (Carcharodon carcharias) are one such species, having exhibited a 270 km range shift of the cold edge of their thermal range extending northward to the Monterey Bay. However, little is known about the fine-scale habitat selection of marine organisms at the cold edge of their shifting range and how localized thermal gradients or warm pools may permit persistence in these newly inhabited locations. The Monterey Bay …

Unveiling Dynamics Of The Monterey Bay Upwelling Shadow Front: Insights From Dorado Auv Time Series, Kieran R. Claassen

Capstone Projects and Master's Theses

This thesis investigates the fine-scale dynamics of the Monterey Bay upwelling shadow front by integrating autonomous underwater vehicle (AUV) observations with environmental DNA (eDNA) analysis. Using a clustering technique on temperature-salinity profiles from 29 missions, I identified distinct water masses that consistently reflected seasonal and spatial hydrographic structure. Phytoplankton communities, resolved via eDNA and robust Aitchison Principal Component Analysis (PCA), exhibited clear seasonal transitions-from diatom-dominated assemblages during peak upwelling to dinoflagellate-enriched communities in warm, stratified shadow waters in the fall. Case studies during sustained upwelling revealed front-associated differences in community composition, supported by ordination and statistical testing. Notably, t-tests comparing …

Query Understanding In Llm-Based Conversational Information Seeking, Yifei Yuan, Zahra Abbasiantaeb, Mohammad Aliannejadi, Yang Deng

Research Collection School Of Computing and Information Systems

Query understanding in CIS involves accurately interpreting user intent through context-aware interactions. This includes resolving ambiguities, refining queries, and adapting to evolving information needs. LLM enhance this process by interpreting nuanced language and adapting dynamically, improving the relevance and precision of search results in real-time. In this tutorial, we explore advanced techniques to enhance query understanding in LLM-based CIS systems. We delve into LLM-driven methods for developing robust evaluation metrics to assess query understanding quality in multi-turn interactions, strategies for building more interactive systems, and applications like proactive query management and query reformulation. We also discuss key challenges in integrating …

The Aggregate Welfare And Trade Implications Of Contracting Frictions In Global Sourcing, Davin Chor, Lin Ma

Research Collection School Of Economics

How much do contracting frictions between global firms and their suppliers impact country welfare and trade? We answer this by developing a model of global sourcing under partial contractibility, where firm-supplier relationships are exposed to a bilateral holdup problem. Sourcing decisions aggregate into a gravity equation for trade flows by organizational mode (intrafirm vs. arm’s length), which we take to structural estimation. We can then evaluate welfare changes with an extended Arkolakis, Costinot and Rodriguez-Clare (2012) formula that incorporates these contracting frictions. Our counterfactual analysis reveals a sizeable average country welfare gain of 9.2% from eliminating contracting frictions in global …

High Frequency Factor Analysis With Partially Observable Factors, Dachuan Chen, Wenqi Lu, Siyu Xie

Research Collection School Of Economics

This paper considers a novel factor structure – Partially Observable Factor Model – where both observable factors and latent factors exist in the model simultaneously. Such factor structure can make sure both interpretability and goodness-of-fit at the same time. Necessary estimation methodologies for this partially observable factor model are developed in this paper for the high frequency data. The proposed estimation methodology is robust to jumps, microstructure noise and asynchronous observation times simultaneously.When the observable factors are exogenous, we provide the estimation theory for the integrated eigenvalues of the residual covariance matrix, which including the bias-corrected estimator, central limit theorem …

Grazing On The Early Life History Stages Of Macrocystis Pyrifera By The Purple Sea Urchin Strongylocentrotus Purpuratus, Sloane Lofy

Capstone Projects and Master's Theses

In California, recent large-scale declines in kelp forest cover, the formation of sea urchin barrens, and the subsequent biodiversity loss have heightened the need to further investigate mechanisms of kelp forest recovery and sea urchin barren dynamics. To better understand the kelp recruitment potential of these deforested areas it is important to determine the effect sea urchins have on the microscopic portion of the kelp lifecycle and if a size refuge exists. Laboratory studies were used to examine the effect of the purple sea urchin Strongylocentrotus purpuratus on the density, percent cover and reproductive output for three microscopic stages of …

Psychosocial Supports For The Physical And Mental Health Of Youth With Autism And Other Neurodevelopmental Disabilities., Melissa Campbell, Elizabeth Hastings, Paige Mcardle, Darren Olsen, Kathryn Benton, Cy Nadler

Manuscripts, Articles, Book Chapters and Other Papers

One in six youth has a neurodevelopmental disability (NDD), and autism diagnostic rates continue to rise. Before and after a diagnosis, families need trusted sources of guidance to navigate co-occurring medical and psychological conditions, and to manage unique stressors including transition to adulthood. However, medical professionals from all specialty areas struggle to identify resources to support the complex psychosocial and healthcare needs of these patients and their families. This primer on psychosocial supports for youth with autism will explore the major mental and physical health stressors faced by affected youth and families, and discuss opportunities for primary care and other …

Mechanical Engineering Virtual Reality Lab, Alan Mcdonnell

Case studies: Digital Education

Students perform multiple engineering lab experiments within the Critical Utilities 1 module. The ‘Pump Laboratory’ experiment involves interaction with a fluid power training rig to record pressure and flow readings from a variety of system states. The recorded data from multiple pumping experiments is used to create pump and system characteristic curves and charts. This experiment is very appropriate to industrial practice and design. The typical cohort size is 10+ and the availability of only one training rig introduces a ‘pinch-point’ in the interaction capacity of the students; there is insufficient time for all students to perform all the separate …

An Evening With Mobile Hyflex, Peter Alexander

Case studies: Digital Education

Network Security is a 10-credit module taught on the part-time Bachelor of Science in Computing in Digital Forensics & Cyber Security course in TU Dublin. While the overall course is mainly delivered online, there are some topics in this particular module which benefit from having a hands-on interactive element. The challenge though with facilitating learners to have that interactive experience is that the ones who cannot travel to campus should not be excluded. The mobile Hyflex project helped address this challenge by giving students both on campus and online a comparable interactive experience. Changes made to practice (100-150 words).

Hyflex To Online: A Cautionary Tale, Joseph K. Fitzgerald

Case studies: Digital Education

This module was delivered to two undergraduate part-time cohorts. One of the cohorts had a significant requirement for flexibility, as many students could be called into work with little notice. Historically, this group had engaged with online-only classes. However, with the installation of Hyflex technology, it was considered that some limited face-to-face (F2F) engagement could be reintroduced to enrich the learning experience. The intention was that Hyflex could offer the best of both worlds: the flexibility of online access and the interpersonal benefits of F2F learning. The ambition was to support flexibility while reintroducing classroom presence where feasible.

Using The Ms Surface Pro 9 To Enhance Teaching And Learning, Anthony Reynolds

Case studies: Digital Education

Thermodynamics is a fundamental subject for mechanical engineers, focusing on the principles of energy conversion and the behaviour of matter under various conditions.Thermodynamics is very challenging for students for several reasons: It involves abstract concepts like entropy, which can be difficult to visualize and understand. It requires a strong grasp of mathematics(e.g.,calculus),which can be intimidating for somestudents. It intersects with various fields(e. g.physics and chemistry) requiring students to integrate knowledge from different areas.

Health, Human Performance and Recreation Faculty Publications and Presentations

Objective: Physical activity opportunities, such as recess, in educational settings are vital yet only a handful of states have policies in place to ensure daily minimum recess allotment. We aim to investigate associations between physical activity during recess and other time periods to better understand the extent to which recess physical activity is related to physical activity throughout the week. Methods: Children K-5th grade were from four schools in Little Rock, Arkansas. Children wore accelerometers on their waist to assess physical activity across the week. Chi-square and t-tests or Wilcoxon rank-sum tests and multi-level mixed effects generalized linear regression were …

Enhancing Phenotyping Accuracy For Selection Of Urochloa Spp. Tolerant Genotypes To Red Spider Mite (Oligonychus Trichardti), Paula Espitia-Buitrago, José Miguel Cotes Torres, Luis Miguel Hernández, Juan Andres Cardoso, Frank Chidawanyika, Rosa N. Jauregui

All Peer-Reviewed Publications

The red spider mites are a major biotic limitation to productivity for Brachiaria (Urochloa spp.) grasses in tropical Eastern Africa, causing severe economic losses mainly in the dry seasons. However, due to the lack of reports of integrated pest management strategies, genetic resistance can play a crucial role in Brachiaria-based livestock systems, minimising the impact of this pest. The objective of this study was to develop and validate a methodology for accurately categorising resistance responses in Urochloa genotypes to identify potential sources of resistance to the Western Kenya red spider mite Oligonychus trichardti (Meyer 1974). Accordingly, 25 genotypes of Urochloa …
