Not Just Monetary: Arts And Humanities Scholars’ Perspectives On The Costs Of Open Access Publishing, Lindsey Skaggs, Rachel Scott, Colby Cilento

Faculty and Staff Publications – Milner Library

Bibliometric and survey-based studies have documented different open access (OA) publishing practices among scholars across academic disciplines. This article reports on interviews conducted with arts and humanities scholars from the United States and explores how OA intersects with their research and publication practices. Beyond the considerable financial costs of OA publishing, findings demonstrate that arts and humanities scholars contend with opportunity, reputational, equity, and time costs as they consider and engage with OA publishing. The authors discuss the implications of these costs for librarians who facilitate the dissemination, discovery, and preservation of arts and humanities scholarship.

Pulse Wave Velocity In Atrial Fibrillation: A Scoping Review Of Clinical Relevance, Oren G. Nedjar, Zaneh Kahook, Syed Maaz Shah, Christos G. Mihos, Marc M. Kesselman

Student Publications

Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia and is associated with high morbidity, mortality, and healthcare burden. Arterial stiffness (AS) alters cardiac loading conditions and contributes to ventricular arterial uncoupling (VAC), diastolic dysfunction, and atrial remodeling. Pulse wave velocity (PWV) is the standard noninvasive measure of AS, but its role across the spectrum of AF has not been clearly defined. This scoping review assessed the existing literature on PWV and AF, with attention to disease onset, clinical characteristics, progression, treatment response, and outcomes. A scoping review was conducted following Preferred Reporting Items for Systematic reviews and Meta-Analyses …

Bouveret Syndrome: A Systematic Review Of Clinical Factors Associated With Surgical Management, Maximus S. Reese, Salma Alkhatib, Philip J. Haynos, Garret Rymer, Noor Chughtai, Jared Nichols

Student Publications

Bouveret syndrome is a rare form of gallstone ileus characterized by the formation of a cholecystoenteric fistula and subsequent gallstone migration into the gastrointestinal tract, resulting in gastric outlet obstruction. Diagnostic criteria consist of clinical evidence (persistent non-bilious vomiting, nausea, epigastric pain) paired with imaging (CT abdomen showing ectopic gallstone, gastric outlet obstruction, cholecystoenteric fistula) and endoscopy. Current expert consensus recommends initial endoscopic stone removal as first-line therapy to avoid techniques associated with higher morbidity and mortality. This review focuses on identifying recurrent findings in clinical and stone-related factors observed in endoscopic failure to determine any features that may guide …

Visual Cues Elicit Differential Aggression Towards Female And Female Mimics In The Corkwing Wrasse, Benjamin A. Ellis, Tonje K. Sørdalen, Mark Briffa, Anne Berit Skiftesvik, Alexander D.M. Wilson, Kim A.T. Halvorsen

School of Biological and Marine Sciences

Alternative reproductive tactics (ARTs) are consistent intrasexual differences in behavior that maximize reproductive success through different means. In corkwing wrasse (Symphodus melops), smaller males mimic female visual morphology (hereafter sneakers) to steal fertilizations from nest-building parental males (hereafter nesting males). We investigated whether this visual mimicry effectively deceived 47 nesting males across 4 sites by quantifying 2 agonistic responses (attack latency and attack frequency) to models depicting unfamiliar females, sneakers and rival nesting males. Contrary to expectations, nesting males exhibited faster agonistic responses towards female models, with lower attack latencies compared with both male types. Additionally, the relationship between model …

Low Climate Benefit Of Nordic Coastal Marshes: Site Conditions Outweigh Grazing Effects And Shape Trade-Offs Between Carbon Storage And Its Stability, Carmen Leiva-Dueñas, T. Banta, Christoffer Boström, Franziska Eller, Johan Eklöf, Line Holm Andersen, Kai Jensen, Marianna Lanari, Ella Logemann, Pere Masque, Thomas Ostertag, Christoph Reisdorff, Anaïs Richard, Anu Vehmaa, Jukka Alm, Mikael Von Numers, Dorte Krause-Jensen

Research outputs 2022 to 2026

Coastal marshes, recognized as effective organic carbon (OC) sinks, have gained attention for their potential contribution to climate mitigation through protection and restoration. However, the climate mitigation potential of Nordic coastal marshes remains understudied, likely due to their heterogeneous and often non-tidal nature. To fill this gap, we examined soil OC storage and accumulation rates, and the effects of grazing, a common management practice, across eight Nordic coastal marsh areas spanning broad climate and environmental gradients. We also assessed soil methane emissions in selected areas. The Nordic marshes studied store a median of 7 kg OC m⁻² (interquartile range, …

Why Followership Matters In Psychiatry: Rebalancing Our Obsession With Leadership, Rohit Shankar, Richard Laugharne, Regi Alexander, Kenneth R. Kaufman, Derek K. Tracy, Fabida Aria, Mayura Deshpande, Matthew Frost

Peninsula Medical School

SummaryPsychiatry emphasises leadership development, but neglects the equally universal and essential role of followership. Although most clinicians spend more time as followers than leaders, literature overwhelmingly favours leadership. Drawing on healthcare, socio-religious traditions and management science, the authors reframe followership as an active, values-driven role grounded in trust, motivation and moral courage rather than passive compliance. This editorial argues that effective followership is active, ethical and courageous. Nurturing good followers in mental health services is essential for good patient care, organisational integrity and sustainable leadership. Cultivating active followership strengthens safeguarding, transparency and organisational legitimacy. The editorial calls for psychiatry and …

Peninsula Medical School

BACKGROUND: Long COVID (LC) affects around two million people in the UK and over 65 million people globally. Antiviral medications have shown positive effects in reducing the risk of progression to severe disease in high-risk patients during an acute SARS-CoV-2 infection and have improved outcomes in those living with LC. Research testing the feasibility and efficacy of antiviral medications is ongoing, and clinical trials should determine the use of Remdesivir and its impact on LC symptoms, patient-reported outcomes, quality of life and functional status.

METHODS: Seventy-two patients ≥ 18 years of age who have a confirmed LC diagnosis will be …

Pre- And Syn-Eruptive Processes During Ancient Pre-Caldera Activity At Campi Flegrei (Italy): Petrology And Chemostratigraphy Of The Vitafumo And Miliscola Tuff-Cones, Lorenzo Fedele, Claudio Scarpati, Annamaria Perrotta, Ileana Santangleo, Federica Güll, Paul Cole

School of Geography, Earth and Environmental Sciences

A detailed petrological investigation of the juvenile clasts from the deposits of the Vitafumo and Miliscola tuff cones is reported here, representing the first attempt to reconstruct the architecture of the plumbing systems of Phlegraean volcanoes preceding the caldera-forming Campanian Ignimbrite (CI) eruption. The Vitafumo and Miliscola juvenile clasts are remarkably crystal-poor to nearly aphyric, with sparse microphenocrysts of mostly sanidine, plus some plagioclase in the slightly crystal-richer and older Vitafumo samples. Groundmass glass compositions are trachytic and homogeneous for each volcano, with only slightly higher MgO, CaO and K ₂O and lower Na ₂O in the Miliscola …

Maximal Motor Unit Firing Rates Decline With Amyotrophic Lateral Sclerosis Progression, Gabriel L. Fernandes, Lucas B.R. Orssatto, Matheus D. Pinto, Joao S. Henkin, Ehsan Shandiz, Pamela A. Mccombe, Robert D. Henderson, Gabriel S. Trajano

Research outputs 2022 to 2026

Objective: Amyotrophic lateral sclerosis (ALS) is characterised by progressive degeneration of upper and lower motor neurons and their motor units (MUs). MU loss is compensated by collateral sprouting and reinnervation of muscle fibres. There is limited information about the properties of these surviving MUs as these processes take place. High-density surface electromyography (HD-sEMG) decomposition enables non-invasive analysis of individual MU firing behaviour during maximal voluntary contractions and assess their changes with ALS progression. Methods: Thirty-nine individuals with ALS (24 men; mean age 63 ± 16 years) completed up to five visits (interval 20.0 ± 7.9 weeks). Tibialis anterior HD-sEMG recordings …

Interview No. 1820, Alma Chavaria (Alma Najera)

Combined Interviews

Alma Chavira (now Chavira de Nájera), born in 1954 in El Paso, Texas, experienced a childhood defined by the fluid boundaries of the border region. Although she was raised in Juárez until the age of 14, she attended a private Catholic convent school in El Paso through the sixth grade, a routine that involved a complex daily commute via bus, streetcar, and foot across the international bridge. Describing her upbringing as "pocha," she recalls the seamless transition of speaking Spanish at home in Juárez and English at school in El Paso. When the rising costs of private tuition and uniforms …

A Federated Learning Framework For Data-Sovereign Predictive Maintenance In Distributed Smart Manufacturing, Md Sazol Ahmmed, Sriram Praneeth Isanaka, Frank Liou

Mechanical and Aerospace Engineering Faculty Research & Creative Works

Featured Application: The proposed federated learning framework can be applied in distributed smart manufacturing environments where multiple factories or production facilities collaboratively develop predictive maintenance models without sharing sensitive operational data. This approach is particularly useful for industrial networks involving geographically distributed plants, contract manufacturing partners, and multi-site production systems where data sovereignty and avoidance of raw data sharing are critical. Predictive maintenance enables early detection of machine failures and reduces unexpected production downtime. However, conventional approaches typically rely on centralized data collection and model training which introduce challenges related to data sovereignty, communication overhead and data ownership. To address …

Machine Vision For In Situ Measurement And Control Of Wire Stickout In Lwded Process, Braden Mclain, Remy Mathenia, Todd Sparks, Frank Liou

Mechanical and Aerospace Engineering Faculty Research & Creative Works

This work presents a machine-vision–based measurement and control framework for laser wire directed energy deposition (LWDED) processes. A visible-light camera system is used to capture meltpool images, from which a novel vision algorithm extracts the wire–meltpool interface location. By utilizing a camera that is rigidly mounted to the deposition head, the vision algorithm provides a relative measurement of the distance between the nozzle tip and the workpiece, also referred to as wire stickout. A proportional-derivative (PD) control strategy is implemented using the measured stickout as feedback to adjust deposition feedrate. Results show that the control system successfully compensates for improper …

Causality-Driven Test Case Minimisation For Cyber-Physical Systems, Michael Foster, Christopher M. Poskitt, Nicholas R. Latimer, Neil Walkinshaw, Richard Somers, Robert M. Hierons

Research Collection School Of Computing and Information Systems

Cyber-physical systems allow digital control systems to interact with the physical world using sensors and actuators. They are increasingly being used to automate critical infrastructure, where software faults can have dire consequences. Due to the complex nature and unpredictability of these systems, their resilience is often tested using a technique called fuzzing, which generates quasi-random sequences of sensor and actuator manipulations with the goal of forcing a system into unsafe states. However, there is currently no way of determining which manipulations of a test case cause a failure without systematically removing each one and re-running the test, which can be …

Natural Adversaries: Fuzzing Autonomous Vehicles With Realistic Roadside Object Placements, Yang Sun, Haoyu Wang, Christopher M. Poskitt, Jun Sun

Research Collection School Of Computing and Information Systems

The emergence of Autonomous Vehicles (AVs) has spurred research into testing the resilience of their perception systems, i.e., ensuring that they are not susceptible to critical misjudgements. It is important that these systems are tested not only with respect to other vehicles on the road, but also with respect to objects placed on the roadside. Trash bins, billboards, and greenery are examples of such objects, typically positioned according to guidelines developed for the human visual system, which may not align perfectly with the needs of AVs. Existing tests, however, usually focus on adversarial objects with conspicuous shapes or patches, which …

LSU New Orleans Theses and Dissertations

This research utilized an existing SWMM modeling framework of the Ormond area within St. Charles Parish, Louisiana. A micro scale PCSWMM model was updated using GIS Derived values for CN, percent imperviousness, and subcatchment slope and compared to an macro-scale model. Models were compared under several storm events, which included the recent May 14, 2020 storm as well as 2-, 10-, and 100-year design storms. Peak flow, total inflow volume, and hydrograph characteristics were analyzed to assess response of each model.

The results show that the macro-scale model generally produces higher peak flows and total volumes, while the micro-scale model …

Exploring The Impact Of University-Recognized Spaces On Racial Battle Fatigue Among Black Faculty & Staff At Historically White Institutions, Tiffany M. Courseault

LSU New Orleans Theses and Dissertations

Black Faculty and Staff (BFS) at Historically White Institutions (HWIs) navigate environments shaped by racial microaggressions, systemic inequities, and institutional marginalization. These conditions contribute to Racial Battle Fatigue (RBF), a psychological, behavioral, and physiological response to sustained exposure to racialized stress. While institutional Diversity, Equity, and Inclusion (DEI) initiatives are often positioned as mechanisms for improving campus climate, existing research suggests they frequently fail to address the lived realities of BFS. This study examined how university-recognized communal spaces function as critical sites of support, resistance, and mitigation within these environments.

Using a narrative inquiry methodology, this study explored the lived …

The Impact of the Veto on the Effectiveness of the Security Council in Contemporary International Conflicts: "An Analytical Study"

The League of Nations, which was established in 1919 after World War I to maintain peace, failed in its mission. Therefore, in 1945 the victorious allies established the United Nations through San Francisco Conference on June 25, 1945. This was followed by the establishment of the Security Council, with its primary responsibility in maintaining international peace and security. The establishment of the Security Council represented a tremendous hope for achieving world peace after the horrors of World War II. However, The …

Library Philosophy and Practice (e-journal)

Scholarly communication in the digital era is becoming influenced by the problems of manuscript preparation, journal choice, and peer review in spite of the blistering technological progress and open-access publication development. Researchers frequently encounter difficulties with academic standards in writing, professional ethics of publication, engaging in the search of reliable journals, navigating complex editorial and peer review procedures, which are all the factors affecting the quality, credibility, and visibility of the research products. It follows a narrative literature review methodology to examine academic publications between 2015 and 2025, which will help to determine the main trends, organizational issues, and new …

Using Picturebooks In Elementary School To Support Discussion, Connection, And Community Action, Polly Parkinson

All Graduate Theses and Dissertations, Fall 2023 to Present

Children are in school to acquire knowledge, so the books they read are a significant influence on how they see themselves and others. School curricula often lack diverse voices, which may limit students’ views of themselves and how they relate to their communities. The research objective of this study was to examine the potential for fostering empathy in students, to encourage societal benefits of positive community behaviors, deepen understanding of history, and future contributions to an engaged democratic society.

The problem identified was that although much research exists discussing children’s literature and empathy, little explores whether that empathy leads to …

How Ai Destroys Institutions, Woodrow Hartzog, Jessica Silbey

Faculty Scholarship

Civic institutions—the rule of law, universities, and a free press—are the backbone of democratic life. They are the mechanisms through which complex societies encourage cooperation and stability, while also adapting to changing circumstances. The real superpower of institutions is their ability to evolve and adapt within a hierarchy of authority and a framework for roles and rules, while maintaining legitimacy for the knowledge produced and the actions taken. Purpose-driven institutions built around transparency, cooperation, and accountability empower individuals to take intellectual risks and challenge the status quo. This happens through the machinations of interpersonal relationships within those institutions, which broaden …

Revocation Reconsidered: Probation Advocacy Through A Litigation Lens, Shira M. Diner

Faculty Scholarship

Being found in violation of probation has dire consequences. The person found in violation can be imprisoned, upending them from their job, family, and community. Unlike incarceration after a criminal trial, a sentence after a violation of probation is not the result of a legal process characterized by robust due process protections. It is also often not the result of a forceful and thorough defense. It is instead the consequence of a hearing where lawyers with the fixed mindset of an inevitable finding of a violation don’t engage in the same preparation that they would if it was a trial. …

Foreword: The Universities Will Not Save Us, Jonathan Feingold

Faculty Scholarship

In the spring of 2024, thousands of university students joined campus protests advocating for Palestinian human rights and calling on their institutions to divest from Israel’s military assault on Gaza.1 The student action echoed historical protest movements that universities routinely celebrate in their brochures, monuments, and signage.2 Yet rather than embrace their students’ principled activism, universities across the country deployed militarized force against their own communities.3 From elite Ivies in the northeast, to large privates in the Midwest, to state schools in Texas and California, administrators greeted peaceful protest with discipline, smears, and physical violence.

The First Cut Is The Deepest: Understanding Learner Trauma In The Emergency Medicine Clerkship, Dimitrios Papanagnou, Leela Raj, Karen E. Watkins, Xiao C. Zhang, Andres Fernandez, Md, Victoria J. Marsick

Department of Emergency Medicine Faculty Papers

BACKGROUND: As third-year medical students transition into high-stakes, high-stress clinical environments like the emergency department (ED), they may experience significant personal trauma. However, little is known about how this trauma is experienced early in their training - specifically during the transition from preclinical to clinical learning environments. This study addresses that gap by exploring third-year medical students' experiences of trauma during the emergency medicine (EM) clerkship through the lens of Trauma-Informed Care (TIC) and identifies workplace factors and intersectional demographics influencing these experiences.

METHODS: This qualitative study used the critical incident technique to explore emotionally-significant events encountered by third-year medical …
