The purpose of this Doctor of Nursing Practice project was to improve antidepressant medication adherence and adherence-focused communication among adolescents in an outpatient psychiatric clinic through staff education on teach-back and motivational interviewing. The practice-focused question examined how teach-back combined with motivational interviewing, compared with usual care, affected medication adherence and depressive symptoms during the implementation period. Staff education included use of a previsit questionnaire, structured visit script, …

Standardized Metabolic Monitoring Protocol For Adult Outpatients Who Are Prescribed Antipsychotic Medications, Abel Bueno Gonzalez

Walden Dissertations and Doctoral Studies

This doctoral project was an organization change process evaluation of a quality improvement initiative in a masked outpatient mental health clinic. The practice challenge was poor metabolic monitoring and documentation among adult outpatients taking antipsychotics that were not in line with guidelines. This problem is relevant to nursing practice because use of antipsychotic medications raises risk for weight gain, dyslipidemia, hypertension, and glucose abnormalities, and not monitoring risks may delay referral or management. The practice-focused question was: According to evidence, among adult patients who are prescribed antipsychotic medications in an outpatient mental health clinic, what is the impact of implementing …

Predictive Analytics For Nurse Staffing Optimization And Patient Outcomes, Rhonda Lynn Fisher

Walden Dissertations and Doctoral Studies

This evidence-based quality improvement project assessed the use of a Predictive Analytics Staffing Decision-Support Tool (PASDST) to enhance nurse staffing alignment, workforce planning, and patient outcomes in an acute care setting. Traditional staffing relied mainly on historical census data and fixed nurse-to-patient ratios, with limited real-time information on admissions, discharges, census, and patient acuity. Guided by the Johns Hopkins Evidence-Based Practice Model, a 12-week pilot of PASDST was conducted on one acute care unit. Baseline data from 30 stakeholders—five nurse managers and 25 bedside nurses—were collected. Quantitative responses were analyzed via frequencies and percentages, while open-ended responses underwent thematic analysis. …

Ammonium Phosphate Fertilizers Are A More Effective Phosphorus Source Than Superphosphate For Wheat Grown On Acidic Gravelly Soils, Craig A. Scanlan, Raj Malik, Fien Degryse, Andrew Van Burgel, Mike J. Mclaughlin

Grain and Other Field Crops Research Articles

Selecting the most effective phosphorus (P) fertilizer source is essential for maximizing crop yields. However, there is little information to guide the choice between the widely used soluble granular sources: ammonium phosphates and superphosphates. The aims of this study were to examine whether there are differences in wheat (Triticum aestivum L.) grain yield response to ammonium phosphate and superphosphate fertilizers in field conditions, and if these differences relate to diffusion of P from fertilizer granules. Two field experiments were conducted on acidic gravelly soils in Western Australia where P deficiency occurs to compare wheat growth response to P applied …

Acceptability And Impact Of Weight Management Interventions For Adults With Intellectual Disability: Protocol For A Systematic Review And Meta-Analysis, Rohit Shankar, Ananya Ananthakrishnan, Edward Meinert, Rosiered Brownson-Smith

Peninsula Medical School

Introduction Obesity disproportionately impacts people with intellectual disabilities (PwID). Given the challenges that PwID face, such as cognitive deficits, differences in motivation and communication difficulties, the need for tailored interventions for weight management in PwID is recognised. Yet, this population is underserved, with limited weight management interventions for them compared with the general population. Existing reviews suggest that ‘multi-component’ interventions (including physical activity and dietary advice) are impactful at reducing weight in PwID; however, less is known about how these interventions are tailored for PwID, particularly in addressing their cognitive and communication difficulties which may influence how they understand and …

School of Art, Design and Architecture

This case study investigates the long-term drying kinetics and shrinkage of CobBauge, a wet dual-layer earthen construction system undertaken upon the first UK CobBauge building. The methodology involved the use of Time Domain Reflectometry (TDR) moisture sensors which were laid in a novel dual layer earthen material and enable moisture monitoring within the wall following construction. Average vertical shrinkage during the five-month monitoring period was 43 mm (2.05%), while average Volumetric Moisture Content (VMC) fell from 11%vol to 5.7%vol. There was little lateral movement and shrinkage was non-uniform. The study assessed the long-term drying kinetics of CobBauge in a wet, …

Drivers Of Stopover Distribution Across Two Autumn Migration Routes Of A Long-Distance Afro-Palearctic Migrant, The Common Cuckoo (Cuculus Canorus), Alex Gale, Máire Kirkland, Phil Atkinson, Robert Puschendorf, Chris Hewson

School of Biological and Marine Sciences

Across the globe, many long-distance migratory birds have undergone population declines. Understanding the environmental factors which underly migratory stopover locations can inform conservation strategies for such species. Here, we identify environmental predictors of autumn stopover sites used by UK-breeding male cuckoos (Cuculus canorus) migrating to centralAfrican wintering grounds via two alternative flyways. Between 2011 and 2021, 88 male cuckoos from UK breeding grounds were fitted with <5 g satellite tags connected to the Argos satellite-based tracking system. Filtered stopovers were used to build presence-pseudoabsence distribution models for each flyway, using Boosted Regression Tree and Random Forest algorithms with thirteen climatic, habitat, topographic and anthropogenic variables. Performance was evaluated using 10-fold cross-validation, and weighted ensembles were generated. To assess drought sensitivity, we produced predictions for high- and low-drought years based on Standardised Precipitation–Evapotranspiration Indices (SPEI). Models performed well (AUC=0.79–0.88; TSS=0.50– 0.66) and revealed route-specific environmental predictors. Along the western route, stopover probability was highest in cooler, semi-humid, high-elevation areas with low contemporaneous drought; Iberian mountain ranges emerged as key sites. Along the eastern route, stopover probability was greatest in heterogeneous habitat, with lowlands and uplands favoured over intermediate elevations; the Po watershed appears particularly important. Hunting risk (included to assess anthropogenic threat) was also high at key areas. The spatial extent of stopover regions—and the probability of them being utilised—declined during years ofhigh short-term drought along the western route, and high long-term drought along the eastern route. Whilst Iberian montane stopover regions are sensitive to increasing drought and aridity under climate change, their topographic heterogeneity may provide climatic refuge while limiting intensive land uses. Preference for heterogeneous habitat within the Po watershed highlightsthe need to retain semi-natural habitat within agricultural landscapes. We recommend route-specific conservation measures and higher resolution models using newly available GPS tags to better understand fine-scale site selection within the regions highlighted here.

Trauma Counseling and Resilience

Resilience-building interventions show promise in higher education, yet few studies focus on Latinx college students from migrant farmworker backgrounds (LMFWs), a group facing significant challenges such as acculturative stress, mixed familial immigration status, and educational discontinuity. This quasi-experimental single-case design study examined resilience domains among LMFW students participating in a group-based intervention informed by the predictive 6-factor resilience model. Resilience was measured across six domains: collaboration, vision, tenacity, reasoning, health, and composure, using standardized assessments adapted from Rossouw and Rossouw (2018). Pre- and post-intervention scores were visually analyzed to assess change at the individual level. Results indicated a evidence of …

The Roles Of Adverse And Benevolent Childhood Experiences In Posttraumatic Growth And Social Connectedness Following Interpersonal Trauma, Margaret Poandl, Emily Kitching, Daniel Gutierrez, Yuqi Zhang

Trauma Counseling and Resilience

Interpersonal trauma, such as childhood abuse, neglect, and intimate partner violence, is a prevalent and harmful form of trauma associated with deleterious psychosocial outcomes. Despite its negative impacts, individuals exposed to interpersonal trauma may also experience posttraumatic growth (PTG). While adverse childhood experiences (ACEs) are known risk factors and benevolent childhood experiences (BCEs) are potential protective factors for adult outcomes, little is known about how combinations of ACEs and BCEs influence PTG. This study examined how combinations of ACEs and BCEs relate to PTG and social connectedness among individuals who have experienced interpersonal trauma. Using cross-sectional survey data from 615 …

Phantoms Of The Self: An Art Installation On The Commodification Of Anik-Anik Culture, Vito Lomod, Minuet Deniña, Jaihzel Failana, Joshua R. Marcial

DLSU Arts Congress Conference Proceedings

The practice of anik-anik culture remains relevant and prominent among Filipinos, especially among Gen Z. Decorating, collecting, and preserving miscellaneous items as an extension of one’s identity and memory exemplifies the Filipino maximalist aesthetic. In context, Filipinos are naturally inclined to be maximalists, driven by the desire to connect and the tendency to fill empty spaces, hence the aesthetic of Filipino maximalism. Usually, this is evidenced in, but not limited to, consumption and fashion practices. Correspondingly, its current practices have also sparked discussions about the effects of consumerism and the dilution of the origins of anik-anik, which is deeply rooted …

“Shh!” Bleaching As An Auto-Destructive Art Method Of Representing The Silencing Of Women, Kristelle Tenero De Leon

DLSU Arts Congress Conference Proceedings

This paper discusses the artistic representation of the muffling of women’s voices and the culture of silence through a theoretically auto-destructive method of artmaking—bleaching using mark-making on textile. Through studio art research, the reductive and erasing properties of bleaching agents are used by bleaching printed images of women in fabric to metaphorically represent and articulate the existence of silencing imposed upon women. Guided by the lens of feminism and Gustav Merger’s manifesto of auto-destructive art, this work presents the artistic images of 13 women across Philippine history—from the babaylans to Maria Ressa—on textile, imbued with bleaching effects. Moreover, the work …

Kapwa Beckett: Co-Performance, Pakikipagkapwa, And Relational Meaning-Making In Philippine Stagings Of Samuel Beckett, Christian Gabriel Tolentino

DLSU Arts Congress Conference Proceedings

This reflective-practice study examines how kapwa and pakikipagkapwa emerged through translation, rehearsal, staging, and reception in three Philippine productions of Samuel Beckett: Endgame (2016), Happy Days (2019), and the devised classroom piece Beckett, Godot & Us Waiting (2023). Using comparative production analysis and a dialogical co-performance orientation drawn from Dwight Conquergood, I analyze rehearsal exercises, adaptation notes, production materials, staging decisions, and remembered performer-audience encounters. The analysis identifies distinct relational practices across the productions: collaborative localization and sensory dramaturgy in Endgame; negotiated media adaptation and mediated intimacy in Happy Days; and devising, Meisner repetition, physical trust, and shared post-pandemic waiting …

DLSU Arts Congress Conference Proceedings

With portable digital devices imposing themselves on the already precarious attention span of the Filipino youth, and with raising concerns about degrading literacy of schoolchildren, it is imperative to find creative and entertaining means to inspire the young studentry to engage in dedicated educational materials. This paper explains the methods being used by a small group of artists, scientists and writers to create content for “science entertainment” in comics format. By combining principles of conceptual compression, knowledge indexing and low-elaboration persuasion techniques to develop knowledge “anchors”, the team aims to generate participatory engagement among readers and stimulate their cognitive innovation. …

Indigenous Pedagogies As An Arts-Based Framework For Education 4.0, Andylyn Simeon

DLSU Arts Congress Conference Proceedings

While Education 4.0 promises to cultivate 21st-century skills like creativity and critical thinking, the reality often falls short. Current frameworks are heavily technocentric, prioritizing digital tools and measurable data over the communal, emotional, and spiritual depth that true learning requires. This paper argues that we can restore balance to this digital shift by looking toward Indigenous Pedagogies (IPs). Far from being “obsolete” relics of the past, these are sophisticated, arts-based systems rooted in storytelling, ritual, and land-based creation that can offer a creative blueprint for the human-centered goals that Education 4.0 claims to value. Through a qualitative synthesis, I deconstruct …

Urinary Antimony As A Biomarker For Differentiating Heroin And Brown Mixture Use, Shu-Mei Tsai, Yu-Han Hsiao, Yan-Zin Chang, Sai-Wai Ho

Journal of Food and Drug Analysis

Heroin is classified as a Schedule I controlled substance with severe legal consequences for its use, whereas liquid Brown Mixture (BM) is a legally available and commonly prescribed cough remedy in Taiwan. However, numerous cases of BM ingestion have been misinterpreted as heroin use because BM contains opium tincture, leading to similar urine test results. Owing to the rapid metabolism of heroin, detection of the parent drug and its primary metabolite, 6-acetylmorphine, in urine is difficult; thus, interpretation often relies on morphine concentration and the morphine-to-codeine (M/C) ratio, which can be inconclusive. In our BM analysis, the M/C ratio was …

These models are applied to 2D hypersonic CFD simulations of the Orion reentry …

Resonant Shock Plate Simulation And Prediction Using Modal Substructuring, Harrison C. Denning

Theses and Dissertations

Aerospace structures such as rockets can experience various shock events during flight, such as stage separation or impacts. These shock events can expose components inside the rocket to large accelerations and stresses which in turn can damage the parts. Shocks are often simulated in the lab using a resonant shock plate test. Resonant shock plate testing is often used to qualify aerospace parts, as it can mimic the shocks experienced during launch and stage separations. However, during the course of development, both the definition of the shock environment and the design of the subcomponent tend to change, so that multiple …
