Distributed Software Build Assurance For Software Supply Chain Integrity, Ken Lew, Arijet Sarker, Simeon Wuthier, Jinoh Kim

Faculty Publications

Computing and networking are increasingly implemented in software. We design and build a software build assurance scheme detecting if there have been injections or modifications in the various steps in the software supply chain, including the source code, compiling, and distribution. Building on the reproducible build and software bill of materials (SBOM), our work is distinguished from previous research in assuring multiple software artifacts across the software supply chain. Reproducible build, in particular, enables our scheme, as our scheme requires the software materials/artifacts to be consistent across machines with the same operating system/specifications. Furthermore, we use blockchain to deliver the …

Measuring The Behavior Of The Acoustic Standing Wave Exiting A Flue Organ Pipe, Lauren Krebs Schefter, Whitney L. Coyle, Eric Rokni, Ashley Cannaday

Faculty Publications

Correctly predicting the playing frequencies of a musical instrument is dependent on the length of the resonator with the addition of an end correction. There are multiple theories describing this end correction, perhaps the simplest being that the end correction of a pipe is a physical extension of the sinusoidal pressure standing wave inside the pipe. However, recent optical imaging of the flow in a flue organ pipe found an unexpected exponential decay of pressure just outside of the pipe. This work looks to validate those findings acoustically. A flue organ pipe was played at the 1st, 5th, and 7th …

Adding The Third Dimension: 3d Convolutional Neural Network Diagnosis Of Temporal Lobe Epilepsy, Erik Kaestner, Reihaneh Hassanzadeh, Ezequiel Gleichgerrcht, Kyle Hasenstab, Rebecca W. Roth, Allen Chang, Theodor Rüber, Kathryn A. Davis, Patricia Dugan, Ruben Kuzniecky, Julius Fridriksson Ph.D., Alexandra Parashos, Anto I. Bagić, Daniel L. Drane, Simon S. Keller, Vince D. Calhoun, Anees Abrol, Leonardo Bonilha, Carrie R. Mcdonald

Faculty Publications

Convolutional neural networks (CNN) show great promise for translating decades of research on structural abnormalities in temporal lobe epilepsy into clinical practice. Three-dimensional CNNs typically outperform two-dimensional CNNs in medical imaging. Here we explore for the first time whether a three-dimensional CNN outperforms a two-dimensional CNN for identifying temporal lobe epilepsy-specific features on MRI. Using 1178 T1-weighted images (589 temporal lobe epilepsy, 589 healthy controls) from 12 surgical centres, we trained 3D and 2D CNNs for temporal lobe epilepsy versus healthy control classification, using feature visualization to identify important regions. The 3D CNN was compared to the 2D model and …

Diverse Disconnectedness: Homophily, Social Capital Inequality, And Student Experiences In Law School, Anthony Paik, Swethaa Ballakrishnen, Carole Silver, Steven Boutcher, Tanya Rouleau Whitworth

Faculty Publications

Law school students are encouraged frequently to “network.” However, depending on demographic categories, they may have access to differently resourced social networks in law school. In this article, we draw from our mixed-methods research to explore this diversity of experience, its limitations of access, and the possible network inequalities that may limit the value of legal education to diverse students across different institutional contexts. Using survey and network data (N = 744), collected during the fall of 2019 from three law schools, as well as supplementary interview data (N = 55), we examined students’ social networks, the structures of these …

Previous evidence has shown that migrants and refugees are particularly vulnerable to exclusion and discrimination, and low COVID-19 vaccine intention and uptake were observed among refugees globally. This study aimed to develop and internally validate prediction models of COVID-19 vaccine uptake by nationality.

Methods This is a nested prognostic population-based cross-sectional analysis. Data were collected between June and October 2022 in Sin-El-Fil, a district of Beirut, Lebanon. The study population included a random sample of Lebanese adults and all Syrian adults residing in areas of low …

Journalists Under Attack: Global Perspectives On Threats, Violence And Impunity, Edward L. Carter

Faculty Publications

Journalists are under attack. The digital and physical intimidation and injuries cause harm to not only journalists themselves but also the societies they serve. Society suffers when journalists are silenced because the valuable information they would have provided is prevented from entering the public consciousness. Attacks on journalists are largely met with indifference or ineffective efforts to achieve justice. This impunity emboldens others. This book originated with an international online symposium in 2022 in which scholars and practitioners from around the globe met to discuss not only the problem but also possible solutions.

A Comparison Of Gaussian Processes And Polynomial Chaos Emulators In The Context Of Haemodynamic Pulse–Wave Propagation Modelling, L. Mihaela Paun, Mitchel J. Colebank, Dirk Husmeier

Faculty Publications

Computational modelling of the cardiovascular system is a promising future direction for patient-specific healthcare. However, the computational cost of these simulators is a bottleneck for their practical use in clinic for real-time digital twins. Emulation can overcome this, yet an extensive investigation into cardiovascular emulators is warranted. In this study, we emulate two one-dimensional haemodynamics models of the pulmonary circulation and compare two common emulation strategies: Gaussian processes (GPs) and polynomial chaos expansions (PCEs). We start by reducing the parameter space of the models through global sensitivity analysis, and then compare both emulation strategies using a multivariate, time-series output …

Aspect-Ratio-Dependent Heat Transport By Baroclinic Acoustic Streaming, Jacques Abdul Massih, Remil Mushthaq, Guillaume Michel, Gregory P. Chini

Faculty Publications

Standing acoustic waves have been known to generate Eulerian time-mean ‘streaming’ flows at least since the seminal investigation of Lord Rayleigh in the 1880s. Nevertheless, a recent body of numerical and experimental evidence has shown that inhomogeneities in the ambient density distribution lead to much faster flows than arise in classical Rayleigh streaming. The emergence of these unusually strong flows creates new opportunities to enhance heat transfer in systems in which convective cooling cannot otherwise be easily achieved. To assess this possibility, a theoretical study of acoustic streaming in an ideal gas confined in a rectangular channel with top and …

Closed-Loop Adaptive Optics In The Presence Of Speckle And Weak Scintillation, Derek J. Burrell, Mark F. Spencer, Ronald G. Driggers

Faculty Publications

In this paper, we show that speckle averaging helps to improve adaptive-optics (AO) performance in closed loop as a result of reduced measurement error associated with a Shack–Hartmann wavefront sensor (SHWFS); however, this reduction is rendered ineffective with increasing beacon anisoplanatism. We do so operating in a weak-scintillation regime, where the SHWFS offers robust performance, and using in-plane translation of the illuminated rough surface to accomplish frame-to-frame speckle diversity. Understanding these trade-space limitations is critical when performing AO with non-cooperative, extended-source beacons.

Kvon, Luis Rogério Correa De Oliveira, Erika Monteiro, Danielson Baia Amaral, Thorsten Burmester, Domitille Chalopin, Alexander Suh, Eugene Myers, Oleg Simakov, Igor Schneider, Axel Meyer

Faculty Publications

The genomes of living lungfishes can inform on the molecular-developmental basis of the Devonian sarcopterygian fish–tetrapod transition. We de novo sequenced the genomes of the African (Protopterus annectens) and South American lungfishes (Lepidosiren paradoxa). The Lepidosiren genome (about 91 Gb, roughly 30 times the human genome) is the largest animal genome sequenced so far and more than twice the size of the Australian (Neoceratodus forsteri)¹ and African² lungfishes owing to enlarged intergenic regions and introns with high repeat content (about 90%). All lungfish genomes continue to expand as some transposable elements (TEs) are still active today. In particular, …

Examination Of Photoinduced Radicals In Two Crystal Forms Of Triphenylamine Bis-Urea Macrocycles, Md Faizul Islam, Gamage Isuri P. Wijesekera, Anmon J. Sindt, Mark D. Smith, Linda S. Shimizu

Faculty Publications

This study probes two solvates of triphenylamine (TPA) bis-urea macrocycle 1 and their activated structures to evaluate their maximum photoinduced radicals (PIRs), the subsequent decay of the radicals, and their regeneration. The hierarchical assembly of TPAs shows promise in stabilizing less substituted derivatives, potentially expanding the utility of TPAs that lack stabilizing para-substituents. Single crystal structure analysis reveals that host 1 adopts a planar conformation with the two ureas pointing in opposite directions when dimethoxyethane (DME) is encapsulated within the channel. Whereas previously, 1 adopted a bowl-shaped conformation with the two ureas pointing in the same direction (syn …

The Provenance Of A Pali- And Thai-Language Manuscript At The Rollins College Library: A Buddhist Book Of Merit And Its Long Journey From Southeast Asia To America, Wenxian Zhang

Faculty Publications

Through researching the provenance of a Buddhist manuscript written in the Pali and Thai languages currently held at Rollins, this article seeks to answer the question of how a religious document created in Thailand ended up in a liberal arts college library in America. Regarded as an act of devotion by many Buddhist followers in Southeast Asia, the use of folding manuscripts (samut khoi) has been observed for centuries. The folding manuscripts served as handbooks and chanting manuals for Buddhist monks, who often recited in religious ceremonies while paying tributes to the deceased, with the hope of reincarnation in a …

The Role Of Benthic Fluxes In Acidifying The Bottom Waters In The Northern Gulf Of Mexico Hypoxic Zone Based On An Updated Water Column Biogeochemical-Seabed Diagenetic And Sediment Transport Model, Dongxiao Yin, Linlin Cui, Courtney K. Harris, Julia M. Moriarty, Hannah Beck, Kanchan Maiti

Faculty Publications

The seabed and the water column are tightly coupled in shallow coastal environments. Numerical models of seabed-water interaction provide an alternative to observational studies that require concurrent measurements in both compartments, which are hard to obtain and rarely available. Here, we present a coupled model that includes water column biogeochemistry, seabed diagenesis, sediment transport and hydrodynamics. Our model includes realistic representations of biogeochemical reactions in both seabed and water column, and fluxes at their interface. The model was built on algorithms for seabed-water exchange in the Regional Ocean Modeling System and expanded to include carbonate chemistry in seabed. The updated …

Financial Impacts Of 2020 Labor Day Wildfires To Oregon Highways, Kevin Christiansen, Rubayet Bin Mostafiz, Ayat Al Assi, Robert V. Rohli, Carol J. Friedland

Faculty Publications

Wildfire-caused damage to highways has a significant financial cost to the local, regional, and state jurisdictions where they occur. This study examines the financial ramifications of the harm caused to highways by megafires, using a case study of the highways impacted in the U.S. state of Oregon by the five megafires that occurred during the 2020 Labor Day wildfires. This study proposes a method to classify financial road damage from these wildfires based upon curated datasets collected from the Oregon Department of Transportation (ODOT). Hence, this study presents a dataset with labeled classes, which include physical, roadway, and traffic. Physical …

The Obvious Violation Exception To Qualified Immunity: An Empirical Study, Bailey D. Barnes

Faculty Publications

Qualified immunity shields government officials from civil suits for discretionary actions, as long as the violated right is not clearly established. A right is deemed established when every reasonable official would understand it based on precedent, placing it beyond debate, such that only the plainly incompetent may be held liable. Consequently, even when an act infringes on one's civil rights, a court may deny relief owing to a lack of factually comparable precedent. However, in 2020, the Supreme Court indicated its distrust for overreliance on precedent in certain contexts. In Taylor v. Riojas, the Court held that prison officials violated …

Intimate Partner Violence: Access To Protection Beyond The Pandemic, Rachel J. Wechsler

Faculty Publications

Civil protection orders are the most common legal remedy victims pursue in response to intimate partner violence (IPV). They are more empowering for victims than the criminal legal system because victims themselves drive the process, instead of prosecutors, and they offer more flexible and tailored relief. This Article argues that victims should be able to choose how they file petitions and participate in civil protection order hearings, and that judges should be required to honor those preferences absent good cause. This conclusion is driven by two new, original sets of empirical data collected from IPV survivors who have sought civil …

Workplace Bullying In Louisiana Academic Libraries: Exploring Worker Status And Demographics, Justin Savage, Andrea Hebert, Catherine Baird

Faculty Publications

Bullying is a phenomenon that exists across cultures, societies, and even species. It can be found everywhere, including the workplace. The present study investigates workplace bullying amongst an approximated census sample of Louisiana academic library workers. Using the Negative Acts Questionnaire—Revised (NAQ-R), the study explores the relationships between experiencing workplace bullying and librarian status, tenure status, years in the profession, age, gender, and race. Although no statistically significant relationships were found between variables, the findings add to a growing body of literature that explores the interrelations of demographic and environmental contexts and bullying experiences.

Law Schools Should Substantially Increase Instruction In Mediation Representation, John Lande

Faculty Publications

American law schools generally focus 10% or less of their mediation curriculum on mediation representation. As shown in a survey of faculty teaching mediation and an analysis of course syllabi in this article, most of the instruction focuses on the role of a mediator.

This is a problem for several reasons. New graduates represent clients in mediation much more frequently than they mediate. Clients usually need professional advice to evaluate their cases and develop strategies, which mediators cannot provide. This is precisely the important service that attorneys can provide, but we teach students very little about what to do when …

Toward A Better Understanding Of Mail Balloting: The Case Of U.S. Labor Union-Representation Elections, Rafael Gely, Leonard Bierman, Timothy Chandler

Faculty Publications

The issue of how people vote in elections is important and timely. This Article examines this issue from the perspective of whether people vote by mail - i.e., mail balloting - or in person on a designated election day i.e., in-person voting. It explores the pros and cons of mail balloting versus in-person voting from a general political perspective and in the context of elections for labor union representation in the United States. It presents heretofore unreported data on the use of mail balloting in union-representation elections. It then draws lessons from these data concerning how mail balloting-which has increased …

A New Data-Driven Model To Predict Monthly Runoff At Watershed Scale: Insights From Deep Learning Method Applied In Data-Driven Model, Shunqing Jia, Xihua Wang, Y. Jun Xu, Zejun Liu, Boyang Mao

Faculty Publications

Accurate forecasting of mid to long-term runoff is essential for water resources management. However, the traditional model cannot predict well and the precision of runoff forecast needs to be further improved. Here, we proposed a novel data-driven model aimed at enhancing the performance of the Gated Recurrent Unit (GRU) through the integration of Robust Local Mean Decomposition (RLMD) and the Slime Mould Algorithm (SMA). The objective is to improve mid to long-term runoff prediction in three hydrographic stations: Heishiguan, Baimasi, and Longmenzhen, located within the Yiluo River Watershed in central China. The model leverages monthly runoff data spanning from 2007 …

Extensions Of Open Science For Applied Behavior Analysis: Preregistration For Single-Case Experimental Designs, Matt Tincani, Shawn P. Gilroy, Art Dowdy

Faculty Publications

Open science practices are designed to enhance the utility, integrity, and credibility of scientific research. This article highlights how preregistration in open science practice can be leveraged to enhance the rigor and transparency of single-case experimental designs within an applied behavior analysis framework. We provide an overview of the benefits of preregistration including increased transparency, reduced risk of researcher bias, and improved replicability, and we review the specific contexts under which these practices most benefit the proposed framework. We discuss potential concerns with and unique considerations for preregistering experiments that use single-case designs, with practical guidance for researchers who are …

Long-Term Effects Of Climate Change On Juvenile Bull Shark Migratory Patterns, Philip Matich, Jeffrey D. Plumlee, Walter Bubley, Tobey H. Curtis, J. Marcus Drymon, Lindsay L. Mullins, Oliver N. Shipley, Thomas C. Tinhan, Mark R. Fisher

Faculty Publications

Seasonal variability in environmental conditions is a strong determinant of animal migrations, but warming temperatures associated with climate change are anticipated to alter this phenomenon with unknown consequences. We used a 40-year fishery-independent survey to assess how a changing climate has altered the migration timing, duration and first-year survival of juvenile bull sharks (Carcharhinus leucas). From 1982 to 2021, estuaries in the western Gulf of Mexico (Texas) experienced a mean increase of 1.55°C in autumn water temperatures, and delays in autumn cold fronts by ca. 0.5 days per year. Bull shark migrations in more northern estuaries concomitantly changed, with departures …

Mercury Concentrations In Seaside Sparrows And Marsh Rice Rats Differ Across The Mississippi River Estuary, Andrea Bonisoli-Alquati, Allyson K. Jackson, Collin A. Eagles-Smith, Sydney Moyo, Anna A. Pérez-Umphrey, Michael J. Polito, Allison M. Snider, S. Tyler Williams, Stefan Woltmann, Philip C. Stouffer, Sabrina S. Taylor

Faculty Publications

Mercury (Hg) concentrations and their associated toxicological effects in terrestrial ecosystems of the Gulf of Mexico are largely unknown. Compounding this uncertainty, a large input of organic matter from the 2010 Deepwater Horizon oil spill may have altered Hg cycling and bioaccumulation dynamics. To test this idea, we quantified blood concentrations of total mercury (THg) in Seaside Sparrows (Ammospiza maritima) and Marsh Rice Rats (Oryzomys palustris) in marshes west and east of the Mississippi River in 2015 and 2016. We also tested for a difference in THg concentrations between oiled and non-oiled sites. To address the potential confounding effect of …

Why Is Religious Attendance Linked To More Anxiety In U.S. South Asians? The Mediating Role Of Congregational Neglect, Samuel Stroope, Blake Victor Kent, Anna Boonin Schachter, Alka M. Kanaya, Alexandra E. Shields

Faculty Publications

Objectives: Previous research has identified a positive association between religious attendance and anxiety in U.S. South Asians. The current study assesses the mediating role of congregational neglect as a potential mechanism explaining this association. Design: Analyses relied on data from the Study on Stress, Spirituality, and Health (SSSH) questionnaire in the Mediators of Atherosclerosis in South Asians Living in America (MASALA) study (n = 936), the largest community-based study of health among U.S. South Asians. Analyses were conducted using path analysis and adjusted for a variety of background characteristics. Results: Results confirmed that higher levels of religious service attendance were …
