Fate And Transport Of Per- And Polyfluoroalkyl Substances (Pfas) At Aqueous Film Forming Foam (Afff) Discharge Sites: A Review, Jeffery T. Mcgarr, Eric G. Mbonimpa, Drew C. Mcavoy, Mohamad R. Soltanian

Faculty Publications

Per- and polyfluorinated alkyl substances (PFAS) are an environmentally persistent group of chemicals that can pose an imminent threat to human health through groundwater and surface water contamination. In this review, we evaluate the subsurface behavior of a variety of PFAS chemicals with a focus on aqueous film forming foam (AFFF) discharge sites. AFFF is the primary PFAS contamination risk at sites such as airports and military bases due to use as a fire extinguisher. Understanding the fate and transport of PFAS in the subsurface environment is a multifaceted issue. This review focuses on the role of adsorbent, adsorbate, and …

The response of the hydrological cycle to anthropogenic climate change, especially across the tropical oceans, remains poorly understood due to the scarcity of long instrumental temperature and hydrological records. Massive shallow-water corals are ideally suited to reconstructing past oceanic variability as they are widely distributed across the tropics, rapidly deposit calcium carbonate skeletons that continuously record ambient environmental conditions, and can be sampled at monthly to annual resolution. Climate reconstructions based on corals primarily use the stable oxygen isotope composition (δ18O), which acts as a proxy for sea surface temperature (SST), and the oxygen isotope composition of seawater (δ18Osw), a …

Making Space Behind The Veil: Black Agency Within A Predominantly White Religion, Michael Wood, Grace Ann Soelberg, Jacob Rugh

Faculty Publications

The work of W.E.B. Du Bois highlights the significance of Christian religion in Black American life. According to Du Bois, the Black Church serves as a site of self-formation and affirmation, and the White Church as a source of racist beliefs and justifications for inequality. In this paper, we expand Du Bois’ inquiry about the influence of religion with a study of Black Americans who belong to a predominantly White religion. For those whose religious experience is almost wholly within the “white world,” what role does religion play in their lives? We analyze a set of 52 public accounts by …

Epidemiological Characteristics Of School Playground Injuries, Eric A. Kennedy, Drew A. Filchner, Zane D. Patterson, Heather M. Olsen

Faculty Publications

Reports of children’s play-related injuries have remained stagnant according to epidemiology studies of the past 3 decades. This article provides a unique look into the context of playground injuries within an entire school district, demonstrating the prevalence of these injuries. This study reports that playgrounds are the leading location of school injury, comprising one-third of all elementary school injuries. This study found that while head/neck injuries were the most commonly injured body region within the playground environment, the proportion of head/neck injuries decreased with age, whereas the proportion of extremity injuries increased with age. At least 1 upper extremity injury …

Protocol For Developing A Personalised Prediction Model For Viral Suppression Among Under-Represented Populations In The Context Of The Covid-19 Pandemic, Jiajia Zhang Ph.D., Xueying Yang Ph.D., Sharon Weissman, Xiaoming Li Ph.D., Bankole Olatosi Ph.D.

Faculty Publications

Introduction Sustained viral suppression, an indicator of long-term treatment success and mortality reduction, is one of four strategic areas of the 'Ending the HIV Epidemic' federal campaign launched in 2019. Under-represented populations, like racial or ethnic minority populations, sexual and gender minority groups, and socioeconomically disadvantaged populations, are disproportionately affected by HIV and experience a more striking virological failure. The COVID-19 pandemic might magnify the risk of incomplete viral suppression among under-represented people living with HIV (PLWH) due to interruptions in healthcare access and other worsened socioeconomic and environmental conditions. However, biomedical research rarely includes under-represented populations, resulting in biased …

Jepson, Hugo Melgar-Quiñonez, Roseanna C. Schuster, Justin B. Stoler, Amber Wuitch, Hwise Research Coordination Network

Faculty Publications

Introduction A wide range of water-related problems contribute to the global burden of disease. Despite the many plausible consequences for health and well-being, there is no validated tool to measure individual- or household-level water insecurity equivalently across varying cultural and ecological settings. Accordingly, we are developing the Household Water Insecurity Experiences (HWISE) Scale to measure household-level water insecurity in multiple contexts.

Methods and analysis After domain specification and item development, items were assessed for both content and face validity. Retained items are being asked in surveys in 28 sites globally in which water-related problems have been reported (eg, shortages, excess …

Nucleotide-Driven Molecular Sensing Of Monkeypox Virus Through Hierarchical Self-Assembly Of 2d Hafnium Disulfide Nanoplatelets And Gold Nanospheres, Parikshit Moitra, Maria Iftesum, David Skrodzki, Priyanka Paul, Elnaz Sheikh, Jennifer Lynn Gray, Ketan Dighe, Zach Sheffield, Manas Ranjan Gartia, Dipanjan Pan

Faculty Publications

Liquid interfaces facilitate the organization of nanometer-scale biomaterials with plasmonic properties suitable for molecular diagnostics. Using hierarchical assemblage of 2D hafnium disulfide nanoplatelets and zero-dimensional spherical gold nanoparticles, the design of a multifunctional material is reported. When the target analyte is present, the nanocomposites’ self-assembling pattern changes, altering their plasmonic response. Using monkeypox virus (MPXV) as an example, the findings reveal that adding genomic DNA to the nanocomposite surface increases the agglomeration between gold nanoparticles and decreases the π-stacking distance between hafnium disulfide nanoplatelets. Further, this self-assembled nanomaterial is found to have minimal cross-reactivity toward other pathogens and a limit …

Faculty Publications

This chapter is shared with express permission of Bloomsbury Academic. The full book is available at: https://www.bloomsbury.com/us/access-to-justice-in-rural-communities-9781509951642/ The justice gap persists in many rural parts of the world due to a confluence of economic, cultural, and professional factors at play throughout the justice system and society at large. This justice gap means that people in rural areas experience institutions of justice – including access to lawyers and other legal advice – differently than people in urban areas. Travel, distance, the rural lawyer shortage, and other factors create this difference. No single factor or institution can be blamed for the rural …

Accurate representation of aerosol optical properties is essential for the modeling and remote sensing of atmospheric aerosols. Although aerosol optical properties are strongly dependent upon the aerosol size distribution, the use of detailed aerosol microphysics schemes in global atmospheric models is inhibited by associated computational demands. Computationally efficient parameterizations for aerosol size are needed. In this study, airborne measurements over the United States (DISCOVER-AQ) and South Korea (KORUS-AQ) are interpreted with a global chemical transport model (GEOS-Chem) to investigate the variation in aerosol size when organic matter (OM) and sulfate–nitrate–ammonium (SNA) are the dominant aerosol components. The airborne measurements exhibit …

Why Understanding Food Choice Is Crucial To Transform Food Systems For Human And Planetary Health, Krystal K. Rampalli, Christine E. Blake Ph.D., Rd, Edward A. Frongillo Ph.D., Joseph Montoya

Faculty Publications

What, how and why people eat has long been understood to be important for human health, but until recently, has not been recognised as an essential facet of climate change and its effects on planetary health. The global climate change and diet-related health crises occurring are connected to food systems, food environments and consumer food choices. Calls to transform food systems for human and planetary health highlight the importance of understanding individual food choice. Understanding what, how and why people eat the way they do is crucial to successful food systems transformations that achieve both human and planetary health goals. …

Quantification Of How Mechanical Ventilation Influences The Airborne Infection Risk Of Covid-19 And Hvac Energy Consumption In Office Buildings, Zhihong Pang, Xing Lu, Zheng O’Neill

Faculty Publications

This paper presents an EnergyPlus-based parametric analysis to investigate the infection risk of Coronavirus Disease 2019 (COVID-19) under different mechanical ventilation scenarios for a typical medium-sized office building in various climate zones. A Wells-Riley (WR) based Gammaitoni-Nucci (GN) model was employed to quantitatively calculate the airborne infection risk. The selected parameters for the parametric analysis include the climate zone, outdoor air fraction, fraction of infectors, quanta generation rate, and exposure time. The loss and deposition of particles are not considered. The results suggest that the COVID-19 infection risk varies significantly with climate and season under different outdoor air fraction scenarios …

Tort Reform & The Takings Clause, Bailey D. Barnes

Faculty Publications

The United States tort reform movement has capped noneconomic damage awards in many jurisdictions, thereby preventing the most injured plaintiffs from being fully compensated for their suffering. While litigants have asserted numerous state constitutional challenges to these tort recovery limits, with varying degrees of success, aggrieved plaintiffs have underutilized the Fifth Amendment's Takings Clause. This Article advocates that judicial reduction of a jury's noneconomic damage calculation after the court has informed the successful plaintiff of the full verdict is a regulatory taking in violation of the federal Takings Clause, as incorporated against the states through the Fourteenth Amendment.

Jurisdictional Conflicts In Adult Guardianship, David M. English

Faculty Publications

The case of Britney Spears has shined a spotlight on guardianship, a subject area in which there has been increasing interest in recent years. The events surrounding Ms. Spears s case all occurred in a single jurisdiction, California. But with Americas increasingly mobile population, an individual for whom a guardianship is sought may have contacts with multiple states and, in some cases, foreign countries. Furthermore, following the appointment of a guardian, the guardian or individual subject to guardianship may move to another jurisdiction; it may become necessary to transfer the guardianship proceeding to another jurisdiction or seek ratification of a …

Bayesian Order Constrained Adaptive Design For Phase Ii Clinical Trials Evaluating Subgroup-Specific Treatment Effect, Mu Shan, Beibei Guo, Hao Liu, Qian Li, Yong Zang

Faculty Publications

The “one-size-fits-all’’ paradigm is inappropriate for phase II clinical trials evaluating biotherapies, which are often expected to have substantial heterogeneous treatment effects among different subgroups defined by biomarker. For these biotherapies, the objective of phase II clinical trials is often to evaluate subgroup-specific treatment effects. In this article, we propose a simple yet efficient Bayesian adaptive phase II biomarker-guided design, referred to as the Bayesian-order constrained adaptive design, to detect the subgroup-specific treatment effects of biotherapies. The Bayesian order constrained adaptive design combines the features of the enrichment design and sequential design. It starts with a “all-comers” stage, and subsequently …

Stakeholder Perceptions About Incorporating Externalities And Vulnerability Into Benefit–Cost Analysis Tools For Watershed Flood Risk Mitigation, Thomas H. Douthat, Fahmida Akhter, Rachelle Sanderson, Jerrod Penn

Faculty Publications

Multi-scalar climate hazards in watersheds and growing consideration regarding equity call for innovation in how agencies evaluate and prioritize mitigation and adaptation projects. Benefit–Cost Analysis (BCA) is one approach that is increasingly being applied to decision-making (i.e., FEMA BCA toolkit), but that has not been applied to watershed and equity-based flood management initiatives. This paper addresses this topic and presents a case study evaluating projects for watershed flood and climate mitigation projects by the Louisiana Watershed Initiative (Louisiana, USA). Through semi-structured interviews with stakeholders and practitioners, we found that BCA tool design must be embedded in the program and policy …

Faculty Publications

Objectives: Opioid misuse is a serious public health concern, yet few people seek treatment for this condition. Hospitals may be one opportunity to identify those with opioid misuse and to teach them skills to help manage their opioid misuse upon discharge. We tested the relationship between opioid misuse status and motivation to change substance use among patients admitted with substance misuse to an inpatient psychiatric unit in a medically underserved area in Baton Rouge, Louisiana, who attended at least 1 group session of motivation enhancement therapy combined with cognitive behavioral therapy (MET-CBT) from January 29, 2020, through March 10, 2022. …

Latino Paradox Or Black Exception? Race, Ethnicity, And Crime In The 21st Century, Edward S. Shihadeh, Raymond E. Barranco

Faculty Publications

George Floyd’s murder by a Minnesota police officer sparked outrage, protests, and a re-evaluation of racial inequities in America. Within criminology, we argue, that re-evaluation should include the Latino Paradox, the idea that Latino communities are an exception—a paradox—in that, while they face economic deprivation, they also possess a magical something that makes them resistant to social problems like crime. Unfortunately, this compels the more delicate question; what is the deficiency in Black communities that makes them so vulnerable to crime? However, as we argue here, the Latino Paradox forces a false comparison. Its assumptions with respect to crime are …

Handling And Restraint Induce A Significant Increase In Plasma Corticosterone In Hispaniolan Amazon Parrots (Amazona Ventralis), Shelby N. Parks, Thomas N. Tully, Aspen L. Settle, Christine R. Lattin

Faculty Publications

OBJECTIVE: To measure baseline plasma corticosterone levels in Hispaniolan Amazon parrots (Amazona ventralis) and assess the effects of handling and restraint on corticosterone levels over 1 hour, reflective of what parrots might experience during veterinary care. ANIMALS: 10 male and 12 female Hispaniolan Amazon parrots. PROCEDURES: Each parrot was removed from its cage and wrapped in a towel for restraint similar to that performed in a clinical setting. An initial baseline blood sample was collected in < 3 minutes upon entrance into the parrot room, after which blood samples were taken every 15 minutes for 1 hour (a total of 5 blood samples). An enzyme-linked immunoassay was validated for Hispaniolan Amazon parrots and used to determine concentrations of plasma corticosterone. RESULTS: On average, parrots showed a significant increase in corticosterone between baseline samples and all subsequent postrestraint time points (average baseline corticosterone ± SD: 0.51 ± 0.65 ng/mL). Females, on average, displayed significantly higher corticosterone levels than males after 30, 45, and 60 minutes of restraint (P = .016, P = .0099, and P = .015, respectively). Birds with feather-destructive behavior did not have significantly higher corticosterone levels than birds without the condition (P = .38). CLINICAL RELEVANCE: Understanding the physiological stress response in companion psittacine birds during routine handling will allow clinicians to better evaluate how this may affect the patient's condition and diagnostic test results. Assessing how corticosterone correlates to behavioral conditions such as feather-destructive behavior will provide clinicians with the potential to develop treatment options.

Networks In Motion: The Alliances Of Information Communication Technologies And Mobility Technologies During The 1918 Influenza Pandemic, Miles C. Coleman, Will Mari

Faculty Publications

In this article, we turn back to the 1918 influenza pandemic to throw light on the alliances of information communication technologies and technologies of mobility (such as the car) during the pandemic. We examine newspaper articles, technical publications, and other historical texts to demonstrate that, despite the fact that mobile technologies—such as cellular phones—did not exist during the 1918 pandemic, the telephone and mobility technology nonetheless formed alliances as networks in motion, or social moments in which risk and reward are calculated not simply by the ability to move, but rather the ability to move, while remaining connected, revealing insight …

The Mediational Role Of Motivation In The Model Of Motor Development In Childhood: A Longitudinal Study, Cristina Menescardi, An V. De Meester, Octavio Álvarez, Isabel Castillo, Leen Haerens, Isaac Estevan

Faculty Publications

The aim of this study was twofold: first, to examine the stability of the hypothesized conceptual model of motor development (without and with including various types of motivation) when children are followed up one-year later, and second to examine longitudinally whether changes in one model variable predict changes in other variables, according to the hypothesized pathways in the model. A sample of 361 Spanish students (50.7% girls, 8–11 years old) voluntarily participated in this study. In relation to the first aim, structural equation modeling revealed the expected positive relationship between the model variables in both measurement times. That is: actual …

Nearly-Lossless-To-Lossy Medical Image Compression By The Optimized Jpegxt And Jpeg Algorithms Through The Anatomical Regions Of Interest, Zhongqiang Li, Alexandra Ramos, Zheng Li, Michelle L. Osborn, Waleed Zaid, Xin Li, Yanping Li, Jian Xu

Faculty Publications

Currently, plenty of image data is generated that complicate storage and image transmission. Great efforts have been attempted on how to increase compression ratio (CR) without loss of critical diagnostic information. In this study, we designed two optimized JPEGXT (JPEGXT_OPT) and JPEG (JPEG_OPT) approaches by amplifying discrete cosine transform coefficients and using the entire anatomical region as ROI (region of interest). We found that ROI percentages have a great impact CR: smaller ROI percentages (10–30 %) could obtain a larger CR. Under the near-lossless compression, JPEGXT_OPT could have CRs up to 4.0 under small ROI percentages (10–30 %), while only …
