Staff Education To Improve Preceptors’ Knowledge Base To Adapt Teaching Methods Across Generations, Lucretia Dennise Sanders Jul 2025

Staff Education To Improve Preceptors’ Knowledge Base To Adapt Teaching Methods Across Generations, Lucretia Dennise Sanders

Walden Dissertations and Doctoral Studies

Today’s nursing workforce consists of individuals from multiple generational cohorts, which creates a dynamic mix of nurses whose behavior and work reflect the cultural and historical events that shaped their generation. As the nursing workforce becomes increasingly multigenerational, nurse educators and leaders face growing challenges in ensuring that onboarding practices meet the needs of diverse learners. In the local organization, leaders and clinical educators observed inconsistencies in preceptorship practices and onboarding experiences, particularly for newly hired nurses. As a result, leaders determined that an educational intervention focused on generational teaching strategies was needed. Thus, the purpose of this Doctor of …


Beyond Translating Cultures: Organizational Cultural Brokering And Latin@/E/X Community Resilience After The "Mobile Home Parks" Fire, Christine Atalie Da Rosa Jul 2025

Beyond Translating Cultures: Organizational Cultural Brokering And Latin@/E/X Community Resilience After The "Mobile Home Parks" Fire, Christine Atalie Da Rosa

Dissertations and Theses

As wildfires increase in frequency and severity in rural communities, disaster management agencies are seeking to collaborate with community-based organizations (CBOs) working with rural, low-income Latin@/e/x communities to build wildfire resilience. This qualitative case study examines the critical role of CBOs rooted in their local, predominately low-income Latin@/e/x communities as cultural brokers in supporting Latin@/e/x wildfire survivors following the 2020 "Mobile Home Parks" Fire in a rural county in Oregon. Drawing from 23 semi-structured interviews, three focus groups, a review of relevant documents, and participant observations, the research investigates how Latin@/e/x CBOs navigated the complex cultural landscape between wildfire survivors …


Big Ugly Lumps? (Counter)Terrorism And The Everyday Atmospheres Of Hostile Vehicle Mitigation, Carrie Benjamin, Sam Berlin, Sara Fregonese, Paul Simpson Jul 2025

Big Ugly Lumps? (Counter)Terrorism And The Everyday Atmospheres Of Hostile Vehicle Mitigation, Carrie Benjamin, Sam Berlin, Sara Fregonese, Paul Simpson

School of Geography, Earth and Environmental Sciences

Adopting an atmospheric lens on the everyday and open-ended crisis of contemporary terror threats in cities in Western Europe, this article unpicks the contemporary logics, desires, and effects of the State in matters of urban counterterrorism by exploring the felt qualities and dispositions of the public around Hostile Vehicle Mitigation (HVM) measures in Birmingham (UK). It argues that the atmospheres around counterterrorism that security officials and business representatives aim to produce, which seeks to reassure the public rather than cause alarm, has led to ambivalent acceptance of HVM by city centre users. The paper shifts away from discursive and socio-technical …

Biology: Faculty Publications and Other Works

The universally conserved α-oxoaldehydes glyoxal (GO) and methylglyoxal (MGO) are toxic metabolic byproducts whose accumulation can lead to cell death. In the absence of a known, natural inducer of the GO-specific response in prokaryotes, we exploited RNA-seq to define a GO response in the bacterial pathogen Pseudomonas aeruginosa. The highest upregulated operon consisted of the known glyoxalase (gloA2) and an antibiotic monooxygenase (ABM) domain of unknown function - renamed here Aldehyde responsive quorum-sensing Inhibitor (ArqI). The arqI-gloA2 operon is highly specific to GO induction and ArqI protein responds by migrating to the flagellar pole. An ArqI atomic structure revealed several …

¿Quién Es Responsable? (Who Is Responsible?): Different Framings About The Responsibility To Maintain Bilingualism In The United States, Heidy Sarabia, Diana Perez Valverde

International Journal on Responsibility

This study explores the perspectives of Chicanx/Latinx educational practitioners on the importance of maintaining bilingualism and the strategies employed by individuals and institutions to achieve this goal. Through oral histories, Chicanx/Latinx educational practitioners discussed the individual responsibility of preserving the Spanish language within families and the limitations of individualized strategies. They highlighted the need for institutional support through bilingual education programs, which foster linguistic diversity and cultural pride. Bilingual education programs were identified as key institutional spaces that foster cultural and linguistic pride, promote positive ethnic and racial identity development, and create a sense of belonging for students and their …

Evaluating Generative Ai For Depression Diagnosis: Implications For Counselor Education And Supervision, Matthew Rensi, Chung-Fan Ni, Leo Gonzalez, Jr., Mindi Barta, Cass Dykeman, James Geisler

Journal of Technology in Counselor Education and Supervision

This study evaluated the efficacy of three Generative AI tools—ChatGPT, Claude, and Gemini— in identifying Major Depressive Disorder (MDD) from 119 written clinical case descriptions. Each AI tool determined if cases met DSM-5 criteria for MDD. The results showed significant performance variations, with Gemini demonstrating an accuracy of 97%. These findings suggest the potential for AI assistance in clinical practice, while also underscoring the importance of professional judgment. The implications for counselor education include opportunities to integrate AI tools into training programs, particularly in courses on psychopathology and clinical skills. Educators can use these tools to enhance students’ diagnostic skills …


The State Of Telemental Health Training And Education In Cacrep-Accredited Counselor Education Master’S Programs, Jocelyn Novella, Davide Mariotti Jul 2025

The State Of Telemental Health Training And Education In Cacrep-Accredited Counselor Education Master’S Programs, Jocelyn Novella, Davide Mariotti

Journal of Technology in Counselor Education and Supervision

Despite the frequent use of telemental health (TMH) to deliver clinical mental health counseling, there are few specific guidelines for the teaching of this important topic in CACREP-accredited counselor education programs. This study examined TMH training and education in master’s-level CACREP-accredited counselor education programs by surveying CACREP liaisons (n = 62). The results were analyzed using frequencies, and questions were cross-tabulated with basic information about the programs’ faculty, students, and method of teaching. Results will inform current practices in the training of counselors in this expanding delivery system.

Evaluating Counseling Skills Through Language Style Matching: A Computer-Aided Text Analysis Of Suicide And General Counseling Transcripts, Chung-Fan Ni, Justin Jacques, Charles Silber, Cass Dykeman

Journal of Technology in Counselor Education and Supervision

This pilot study applies Computer-Aided Text Analysis (CATA) to examine Language Style Matching (LSM) in counseling transcripts, offering a novel metric for counselor education and supervision. Analyzing 50 suicide-focused and 100 general counseling sessions using LIWC-22 software, we found high LSM scores in both contexts (suicide-focused: M = 0.906; general: M = 0.903). Bayesian analysis provided moderate evidence (BF01 = 5.048) in support of the null hypothesis, indicating no significant difference between the two session types. The consistently high LSM suggests counselors effectively build strong alliances and align with client goals across topics. LSM analysis provides an objective measure of …

Collective Judo: Ethics And Access To Justice In Mass Arbitration Companies, Michael Doman Jul 2025

Collective Judo: Ethics And Access To Justice In Mass Arbitration Companies, Michael Doman

Pepperdine Dispute Resolution Law Journal

Over the past five years, several law firms have engaged in “mass arbitration.” This strategy involves aggregating hundreds or thousands of arbitrations and filing them all at once against a company, sometimes forcing the company to either pay huge sums to defend all the claims or settle with all the claimants. This Article discusses how mass arbitration coordinated by nonlawyers and companies should be legally protected by courts and regulators, provided that companies in this space erect specific ethical safeguards. Most notably, mass arbitration companies should implement better procedures to obtain informed consent from their customers, using technology to lower …


Not So "Fast And Furious": Why "Adjournment" Pending A Set-Aside Proceeding Could Further The New York Convention's Purposes, Martina Chun Jul 2025

Not So "Fast And Furious": Why "Adjournment" Pending A Set-Aside Proceeding Could Further The New York Convention's Purposes, Martina Chun

Pepperdine Dispute Resolution Law Journal

This Comment considers “adjournment” of enforcement proceedings under Article VI of the New York Convention, which allows a “pause” or a “stay” on enforcement pending a set-aside proceeding. Adjournment is an effective tool when a party initiates a proceeding to set aside, or annul, an award. While adjournment may mean that the enforcement of an award is not as “fast and furious” as some may prefer, it may be the unheralded solution—often overlooked and seldom discussed – that, despite its low profile, can significantly promote efficiency and prevent issues arising from multiple cross-border litigation proceedings.


Being There: Perils Of Disembodied Mediation, Rob Mcniff Jul 2025

Being There: Perils Of Disembodied Mediation, Rob Mcniff

Pepperdine Dispute Resolution Law Journal

Following the growth of online mediation during the COVID-19 pandemic, practitioners and ADR scholars sought to delineate the virtues and shortcomings of the online process. Many report satisfaction with online mediation. Still, critics find the process devoid of emotional experience or otherwise “dehumanizing.” As ADR practitioners contrast online and face-to-face experiences, and recommend a forum to disputing parties, they should acknowledge that online platforms can never replicate physical encounters between embodied persons. This Article draws on the work of 20th century philosophers, psychologists, and sociologists to explore mediation as corporeal encounter between embodied subjects. Online mediation, by constraining the involvement …


Stranger Disputes: When Artificial Intelligence Turns Arbitration Upside Down, Imre Stephen Szalai Jul 2025

Stranger Disputes: When Artificial Intelligence Turns Arbitration Upside Down, Imre Stephen Szalai

Pepperdine Dispute Resolution Law Journal

Arbitration agreements are everywhere in the United States. These agreements already block access to courts in a troubling manner, and pursuant to these agreements, parties must resolve their disputes before a private, human arbitrator with broad, virtually unreviewable powers. However, with the growth of AI, companies could easily redraft their contracts to require arbitration before non-human bots or AI arbitrators instead of a human arbitrator. Based on the history, values, policy, and text of the Federal Arbitration Act (FAA), this Article concludes that the FAA would govern and support the use of an AI arbitrator. As a result, a pre-dispute …


Rapid Increase In Size Of Wedge-Tailed Shearwater Ardenna Pacifica Colony Following Rat Eradication, Danielle Z. Keys, Robert W. Bullock, Clare Keating, Pierre A. Pistorius Jul 2025

Rapid Increase In Size Of Wedge-Tailed Shearwater Ardenna Pacifica Colony Following Rat Eradication, Danielle Z. Keys, Robert W. Bullock, Clare Keating, Pierre A. Pistorius

Marine Ornithology

Invasive mammalian predators have devastating effects on seabird nesting colonies. A census was conducted on breeding Wedge-tailed Shearwaters Ardenna pacifica in 2016 and 2021 on D’Arros Island, Seychelles, which has been rat-free since 2003. Results were compared with an earlier population estimate to assess population growth following the rat eradication. Compared to counts in 2009, we estimated a 10-fold increase in breeding population size, with 2768 (95% confidence interval (CI) 2424–3112) and 2406 (95% CI 2143–2667) breeding pairs in 2016 and 2021, respectively. While the estimated increase is partly attributable to differences in the timing of the conducted census between …


Establishment Of An Incipient Newell’S Shearwater Puffinus Newelli Colony On Maui, Gregory Spencer, Mitchell Craig, Brad Yuen, David Ainley Jul 2025

Establishment Of An Incipient Newell’S Shearwater Puffinus Newelli Colony On Maui, Gregory Spencer, Mitchell Craig, Brad Yuen, David Ainley

Marine Ornithology

We report the development of a colony of threatened Newell’s Shearwater Puffinus newelli (NESH) at Makamaka‘ole, West Maui, USA, a successful first undertaking in the Hawaiian Islands. Efforts involved the construction of two predator-proof fenced areas, removal/control of predators, placement of nest boxes, and social attraction using recorded calls and decoys. Initially, one of the management areas was intended for Hawaiian Petrel Pterodroma sandwichensis (HAPE) and the other for NESH. Exclosures were completed and mammalian predators were removed in 2013, and social attraction began in 2014. Both species almost immediately began flyovers to inspect speakers and by 2015, they had …


Ecological Experiences And Perceptions Of Small-Scale Gillnet And Purse Seine Fishers On Seabirds And Other Non-Target Taxa In The Humboldt Current System, Chile, Cristián G. Suazo, Cristóbal Anguita, Jaime Ojeda, Guillermo Luna-Jorquera, Maritza Sepúlveda, Oliver Yates Jul 2025

Ecological Experiences And Perceptions Of Small-Scale Gillnet And Purse Seine Fishers On Seabirds And Other Non-Target Taxa In The Humboldt Current System, Chile, Cristián G. Suazo, Cristóbal Anguita, Jaime Ojeda, Guillermo Luna-Jorquera, Maritza Sepúlveda, Oliver Yates

Marine Ornithology

Strategies to reduce the negative impacts of fisheries on ecosystems often come into conflict with fishers who have different experiences with, and perceptions of, biodiversity compared to policy makers and fisheries managers. We interviewed 800 fishers along 2400 kilometers of the Humboldt Current System (HCS) coast, assessing fishers’ perceptions of the impacts of marine predators on fishing and their proposals to reduce conflicts with small-scale net fisheries. Vessel captains saw seabirds as positive indicators of fish presence along the HCS (mean probability 62.7%). In contrast, sea lions were perceived negatively, affecting catches for all fishers and causing fishing gear damage …

A Systematic Review Of Trends In Research On Seabird Behavioral Flexibility, M. Candelaria Biagiotti Barchiesi, Laura M. Biondi, German O. García

Marine Ornithology

There has been an increase in interest in the study of behavioral flexibility for its role in how organisms face disturbances and changes in their environment. However, there is not much research on this topic for seabirds, whose conservation status is affected by multiple issues related to changes in their environment. The goal of this paper was to analyze research on seabird behavioral flexibility and to identify knowledge gaps. A systematic review was conducted using academic search engines that included articles published from 1986 to 2022. In the 143 articles that were analyzed, the following were identified: publication date, family …

Characterizing The Diet Of A Threatened Seabird, The Marbled Murrelet Brachyramphus Marmoratus, Using High-Throughput Sequencing, Emily D. Fountain, Paige J. Kulzer, Richard T. Golightly, James W. Rivers, Scott F. Pearson, Martin G. Raphael, Matthew G. Betts, S. Kim Nelson, Daniel D. Roby, Nicholas F. Kryshak, Stephanie Schneider, M. Zachariah Peery

Marine Ornithology

Understanding prey consumption patterns is critical to understanding the ways in which seabirds cope with a changing ocean. However, characterizing the dietary habitats of seabirds can be challenging. In this study, we investigated the diet of the Marbled Murrelet Brachyramphus marmoratus population that lives in waters off California, Oregon, and Washington, USA, using fecal DNA, custom metabarcoding, and high-throughput sequencing. Murrelets were captured at sea by dip-netting at night. Across this region, murrelets consumed highly diverse prey types including 17 fish species and 10 invertebrate species, in accord with previous work indicating the species’ forage on a wide range of …


Breeding Microhabitat Patterns Among Sympatric Tropical Larids, Antonio Garcia-Quintas, Dennis Denis, Christophe Barbraud, Sophie Lanco Bertrand Jul 2025

Breeding Microhabitat Patterns Among Sympatric Tropical Larids, Antonio Garcia-Quintas, Dennis Denis, Christophe Barbraud, Sophie Lanco Bertrand

Marine Ornithology

The selection of breeding microhabitat (nesting sites) affects successful reproduction in seabirds, yet the process of nesting-site selection in sympatric tropical species remains poorly known. During the 2021 breeding season, we assessed nesting-site selection among five larid species at three cays of Cuba and quantified explanatory variables. Random forest classification models were used to assess which landscape features among eight variables best explained site selection by each species. Patterns were clear for most species, especially the highly gregarious Roseate Tern Sterna dougallii, Royal Tern Thalasseus maximus, and Sandwich Tern T. sandvicensis. Patterns were consistent among the study cays. Dominant plant …


Increasing Use Of Artificial Nest Chambers By Seasonally Segregated Populations Of Band-Rumped Storm Petrels Hydrobates Castro At St Helena, South Atlantic Ocean, Annalea Beard, Robert J. Thomas, Elizabeth Clingham, Leeann Henry, Renata Medeiros, Steffen Oppel, Alison Small, Frank Hailer Jul 2025

Increasing Use Of Artificial Nest Chambers By Seasonally Segregated Populations Of Band-Rumped Storm Petrels Hydrobates Castro At St Helena, South Atlantic Ocean, Annalea Beard, Robert J. Thomas, Elizabeth Clingham, Leeann Henry, Renata Medeiros, Steffen Oppel, Alison Small, Frank Hailer

Marine Ornithology

Artificial nest chambers have become a common management tool for monitoring nocturnal burrow-nesting seabirds, although their utility varies among species and locations. The widespread Band-rumped Storm Petrel Hydrobates castro species complex potentially harbours a cryptic species endemic to the South Atlantic. Here we evaluate the installation of artificial nest chambers as a tool for long-term conservation and monitoring of this species, which breeds in two distinct seasons on St Helena. Based on six years of observational data, we analysed factors affecting occupancy, mate and chamber fidelity, and reproductive success to optimise nest chamber installation and to enhance future management. Occupancy …


When Ornithology Meets Ethnology And Archeology: The Birds Of The Bird-Cult At Rapa Nui (Easter Island) And Their Demise, Manuel Marín Jul 2025

When Ornithology Meets Ethnology And Archeology: The Birds Of The Bird-Cult At Rapa Nui (Easter Island) And Their Demise, Manuel Marín

Marine Ornithology

The disappearance of the bird species involved in the bird-cult of Rapa Nui (Easter Island) was examined. The cult was a contest in which the winner gathered the first seabird egg of the year from a near-shore islet, allowing the winner to become the Tangata Manu, or Birdman. This title provided a heightened status, bringing social and economic benefits and a way of being closer to their gods. Three seabird species were involved in the bird-cult: Great Frigatebird Fregata minor, Sooty Tern Onychoprion fuscatus, and the Spectacled Tern Onychoprion lunatus, none of which currently breed in the area. Rock art …


The Potential Of Ecologists To Enhance Our Understanding Of Seabird Health, Melanie R. Wells, Annie Philips, Mary-Anne Lea, Scott Carver Jul 2025

The Potential Of Ecologists To Enhance Our Understanding Of Seabird Health, Melanie R. Wells, Annie Philips, Mary-Anne Lea, Scott Carver

Marine Ornithology

Ecologists play a pivotal role in the detection and investigation of population changes in seabirds and by doing so have significant potential to contribute to enhancing knowledge of seabird health. This review highlights key examples in the literature where ecologists have employed diligent passive health surveillance and/or undertaken targeted investigations of seabirds, strategies that have augmented our knowledge of seabird health at individual and population levels. Within the context of One Health, an integrated approach to perceiving and managing health, this review amalgamates veterinarian and ecology disciplines by summarising auxiliary metrics of clinical health that may be considered for incorporation …

Breeding Parameters Of Yellow-Legged Gull Larus Michahellis In The Largest Moroccan Colony: Natural Versus Urban Nesting Sites, Siham Bellout, Moulay Abdeljalil Ait Baamrane, Mohamed Aourir

Marine Ornithology

We investigated the main differences in the breeding ecology of Yellow-legged Gulls Larus michahellis nesting in urban (city of Essaouira) and natural (Mogador Island) environments on the African Atlantic coast of west-central Morocco during the 2018 and 2019 breeding seasons. This Yellow-legged Gull population is the largest in the southern portion of this species’ range, making it excellent for research on the breeding biology of marginal populations. Over two years, we collected data on nest density, chronology, clutch size, egg dimensions, and hatching success from nests across the city and island. Results showed that nest density averaged 1.26 ± 1.03 …


Digging In! Burrowing Penguins And Surface Predators, Laura X.L. Tan, Kasun B. Ekanayake, Wouter F.D. Van Dongen, Peter Dann, Duncan R. Sutherland, Michael A. Weston Jul 2025

Digging In! Burrowing Penguins And Surface Predators, Laura X.L. Tan, Kasun B. Ekanayake, Wouter F.D. Van Dongen, Peter Dann, Duncan R. Sutherland, Michael A. Weston

Marine Ornithology

A native Australian corvid, Little Raven Corvus mellori, has emerged as a dominant and problematic predator of an ecologically and economically important seabird, the Little Penguin Eudyptula minor. In 2013, ravens successfully preyed upon clutches/broods of the burrow-nesting penguin, especially those in shallower, more accessible burrows. Individual raven size might mediate which ravens attack penguins; smaller ravens may be able to enter burrows more easily; alternatively, larger ravens may be more capable of overcoming penguin parental defence. Here, we consider the predator-prey interactions to assess whether associations with burrow characteristics persisted and examine whether raven size mediated propensity to prey …


Salvin's Albatross Thalassarche Salvini Interacting With Freezer Trawlers In Waters Of The Patagonian Shelf, Rubén F. Dellacasa, Leandro N. Chavez, Leandro L. Tamini Jul 2025

Salvin's Albatross Thalassarche Salvini Interacting With Freezer Trawlers In Waters Of The Patagonian Shelf, Rubén F. Dellacasa, Leandro N. Chavez, Leandro L. Tamini

Marine Ornithology

We present a new record of Salvin’s Albatross Thalassarche salvini in waters of the Patagonian continental shelf. During a seabird census on 06 December 2019, a sub-adult individual within a mixed-species flock was observed eating fishery discards. In addition, we review sightings of this species outside its known core range using published records and other information. The species’ presence in Argentine waters has possibly been underestimated and further work to elaborate its interaction with fishery fleets is required.

Albatross And Petrel Interactions With An Artisanal Squid Fishery In Southern Peru During El Niño, 2015-2017, Cristian Moreno, Javier Quiñones

Marine Ornithology

We report on the occurrence of albatrosses (Diomedeidae) and petrels (Procellariidae) associated with an artisanal small-scale fishery (SSF) for Humboldt Squid Dosidicus gigas in waters of southern Peru during El Niño 2015–2016 and coastal El Niño 2017. We deployed as observers on a number of fishing trips to assess seabird interactions. White-chinned Petrels Procellaria aequinoctialis and Waved Albatross Phoebastria irroata were the most abundant species observed, followed by Salvin’s Thalassarche salvini and Chatham T. eremita albatross, and Cape Petrels Daption capense. The majority of procellariid species (> 60% of total birds) visited while vessels were positioned over the continental slope. …


No Evidence Of Habitat Effect On Clutch Size, Egg Quality, And Hatching Success Of The Yellow-Legged Gull Larus Michahellis At A Micro-Spatial Scale, Sergio Delgado, Nere Zorrozua, Juan Arizaga Jul 2025

No Evidence Of Habitat Effect On Clutch Size, Egg Quality, And Hatching Success Of The Yellow-Legged Gull Larus Michahellis At A Micro-Spatial Scale, Sergio Delgado, Nere Zorrozua, Juan Arizaga

Marine Ornithology

In colonial seabirds, the nest substrate that is available and, in particular, the vegetation cover around the nest, are important environmental factors that drive an individual’s nesting selection process and, ultimately, reproductive performance. Using data collected during three consecutive years in a Yellow-legged Gull Larus michahellis colony from the Bay of Biscay, Spain, we tested whether clutch size, egg volume, and hatching success covaried with the proportion of vegetation cover around nests. We found no effect of vegetation cover on breeding performance. Laying date showed a positive effect on egg volume and a negative effect on hatching success and the …

Reproductive Ecology Of The Black-Necked Swan Cygnus Melancoryphus In A Marine Wetland Of Southern Chile, Jaime A. Cursach, Jaime R. Rau, Claudio N. Tobar, Jonnathan Vilugrón, Francisco Brañas

Marine Ornithology

The Black-necked Swan Cygnus melancoryphus is an endangered species in Chile. After the Río Cruces ecological disaster in Valdivia in 2004 (due to installation of a new pulp mill), the Black-necked Swans that survived were mostly dispersed to marine wetlands of the large island of Chiloé, passing from continental wetlands to the marine environment. The objectives of this study were to provide the first observations of nesting Black-necked Swans in the marine wetland of Chiloé Island, and to identify factors that may affect the survival of their cygnets. Our study was carried out in Caulín Bay (41°49ʹS; 073°38ʹW), Chiloé Island, …
