New Orleans is no stranger to trauma. The Crescent City has a vast history of environmental calamities and oppression. Yet, New Orleans is renowned for its "joie de vivre"—or "love of life." Specifically, this community is known for its unique practice of second-line parades. Researchers have noted the healing power of second-line processions, but none have analyzed the practice and psychology of this ritual through a trauma-informed lens. The aim of this conceptual paper is to begin the conversation, rather than deliver hard fast conclusions, on the potential therapeutic function of second-line parades in response to grief. Relevant literature is presented to illustrate second-line parades, trauma theory, and to provide evidence that the therapeutic effects of second-lining may, in part, be explained by trauma theory. This paper concludes with remarks on conceptualizing the second-line funeral as a sophisticated trauma-informed approach to grief and a note for future research. [ABSTRACT FROM AUTHOR]

As data-driven models gain importance in driving decisions and processes, recently, it has become increasingly important to visualize the data with both speed and accuracy. A massive volume of data is presently generated in the educational sphere from various learning platforms, tools, and institutions. The visual analytics of educational big data has the capability to improve student learning, develop strategies for personalized learning, and improve faculty productivity. However, there are limited advancements in the education domain for data-driven decision making leveraging the recent advancements in the field of machine learning. Some of the recent tools such as Tableau, Power BI, Microsoft Azure suite, Sisense, etc., leverage artificial intelligence and machine learning techniques to visualize data and generate insights from them; however, their applicability in educational advances is limited. This paper focuses on leveraging machine learning and visualization techniques to demonstrate their utility through a practical implementation using K-12 state assessment data compiled from the institutional websites of the States of Texas and Louisiana. Effective modeling and predictive analytics are the focus of the sample use case presented in this research. Our approach demonstrates the applicability of web technology in conjunction with machine learning to provide a cost-effective and timely solution to visualize and analyze big educational data. Additionally, ad hoc visualization provides contextual analysis in areas of concern for education agencies (EAs). [ABSTRACT FROM AUTHOR]

Following the Dobbs v. Jackson Women's Health Organization decision, Republican-controlled legislatures across the U.S. initiated draconian abortion restrictions. In order to appeal to anti-abortion policymakers, advocates across the country have strategically separated "maternal and child health" (MCH) issues, such as increased insurance coverage for midwifery and doula care, from issues often labeled as "reproductive rights," such as access to sex education, birth control, and abortion. Advocates point out this strategic separation has likely contributed overall to the downfall of abortion rights. In this paper, we analyze legislative discourse to understand the legislative challenges advocates face, the strategic separations and allyships they employ, and the implications for other states and reproductive health more broadly. We find that legislators legitimate the same scientific evidence in some contexts while not in others in order to hold onto rhetorical purity within the abortion debate. In their attempts to parse the ideal abortion seeker, conservative legislators create legal ambiguities with serious consequences for healthcare. [ABSTRACT FROM AUTHOR]

This technical paper investigates the influence of sample size and geologic characteristics on the geotechnical design of levee embankments. Sample quality plays a vital role in quantifying engineering properties for levee embankment projects, and numerous studies have highlighted the impact of sample disturbance on such engineering properties. Despite this evidence, conventional tube and piston samplers of different diameters continue to be widely used, potentially leading to underestimation of shear strength. The paper focuses on comparing 7.6 cm and 12.7 cm diameter undisturbed Shelby tube samples and CPT data collected from three levee sites in the Greater New Orleans Area, Louisiana, USA, which encompass diverse geologic histories. The study aims to assess the effect of industry used samples size and geology on levee construction costs. The findings provide valuable insights into optimizing sample collection methods and improving geotechnical design for earthen embankments. [ABSTRACT FROM AUTHOR]

A mediation effect refers to the effect transmitted by a mediator intervening in the relationship between an exposure variable and a response variable. Mediation analysis is widely used to identify significant mediators and to make inferences on their effects. The Bayesian method allows researchers to incorporate prior information from previous knowledge into the analysis, deal with the hierarchical structure of variables, and estimate the quantities of interest from the posterior distributions. This paper proposes three Bayesian mediation analysis methods to make inferences on mediation effects. Our proposed methods are the following: (1) the function of coefficients method; (2) the product of partial difference method; and (3) the re-sampling method. We apply these three methods to explore racial disparities in the diagnostic age of breast cancer patients in Louisiana. We found that African American (AA) patients are diagnosed at an average of 4.37 years younger compared with Caucasian (CA) patients (57.40 versus 61.77, p < 0.0001). We also found that the racial disparity can be explained by patients' insurance (12.90%), marital status (17.17%), cancer stage (3.27%), and residential environmental factors, including the percent of the population under age 18 (3.07%) and the environmental factor of intersection density (9.02%).

This paper delves into integrating technological and social innovations in design through a community-oriented, resilient approach, emphasizing care and sustainability. It explores resource management's application to the local environment and education, focusing on adaptable spaces, active collaboration, and innovative solutions for environmental and social challenges. Developed within the EU Marie Curie-funded TREnD project, it combines 'transition' and 'resilience-building' processes, framing co-creation solutions and tailored innovation policies. The research group conducted theoretical and empirical research in the EU and USA, introducing a place-sensitive approach in managing transition through technological diversification. A case study in Ruston (LA, USA), Camp Alabama, exemplifies inclusive design through circular design and low-tech construction, creating adaptable pavilions for the community. Collaborating with MedCamps of Louisiana, the project designs a shared and inclusive space within budget constraints, emphasizing the pivotal role of architecture in advancing community well-being. Employing a bottom-up approach, the practice engages users, students, teachers, and local stakeholders in co-design, resulting in a people-based citadel of care. Outcomes feature high-design technological projects produced through a "low-tech" approach, allowing adaptability in urban regeneration. The 2023 project received awards, showcasing progress and the potential for replication through standardized methodology. Additional outcomes include educational benefits, training architects for societal needs, and regenerating urban areas by exploiting local resources. [ABSTRACT FROM AUTHOR]

Mitigating tornado damage remains a critical challenge for communities throughout much of the United States. Enhanced construction techniques typically used in hurricane-prone regions are often recommended as at least part of the solution, but the effectiveness of these techniques lacks empirical evaluation. This study investigates the performance of modern wood-frame residential structures in Arabi, LA, constructed to hurricane-resistant standards, that were impacted by a strong tornado on March 22, 2022. Field teams deployed beginning March 25, 2022, just three days after the tornado touched down, capturing perishable data on the building performance using vehicle-mounted surface-level panoramic cameras, forensic engineering investigations, and unmanned aerial systems. This paper describes the field deployments and identifies common failure mechanisms observed by the field teams. Analytical fragility functions are developed based on the load path observations and compared to empirical fragility functions generated from linking the building performance observations with wind speed estimates at each building derived from a parametric wind field model conditioned to tree-fall patterns. The study finds that despite the frequent use of hurricane-resistant hardware, such as hurricane straps and anchor bolts, key weak links elsewhere in the load path compromised the resistance and led to premature failures. The agreement between the empirically- and analytically-derived fragility functions was lacking, demonstrating the challenges that remain in understanding near-surface tornado wind loading and structural response. Nonetheless, the study provides a consensus framework for future tornado assessments that can help improve our understanding of tornado loading through the utilization of reconnaissance data. Further, the study findings on deficiencies in the load paths of homes in hurricane-prone regions have practical value to risk assessments and future construction practices. [ABSTRACT FROM AUTHOR]

At the beginning of his Creole opus The Grandissimes, George Washington Cable refers to Louisiana as "A land hung in mourning, darkened by gigantic cypresses, submerged; a land of reptiles, silence, shadow, decay". This anti-pastoral view of Louisiana as an ecosystem of horrific nature and the very human melancholy it breeds is one that has persisted in popular American culture to the present day. However, the literature of Louisiana itself is marked by its creativity in blending elements of folktales, fairy tales, and local color. This paper proposes to examine the transhuman, or the transcendence of the natural by means of supernatural transformation, in folk horror tales of Louisiana. As the locus where the fairy tale meets the burgeoning Southern Gothic, these tales revolve around a reworking of what Vladimir Propp refers to as transfiguration, the physical and metaphysical alteration of the human into something beyond the human. The focus of this paper will be on three recurring figures in Louisiana folk horror: yellow fever, voodoo, and the Devil. Drawing upon works including Alcée Fortier's collection of Creole folktales Louisiana Folktales (1895), Dr. Alfred Mercier's "1878", and various newspaper tales of voodoo ceremonies from the ante- and post-bellum periods, this article brings together theorizations about the fairy tale from Vladimir Propp and Jack Zipes and historiological approaches to the Southern Gothic genre to demonstrate that Louisiana, in its multilingual literary traditions, serves as a nexus where both genres blend uncannily together to create tales that are both geographically specific and yet exist outside of the historical time of non-fantastic fiction. Each of these figures, yellow fever, voodoo, and the Devil, challenges the expectations of what limits the human. Thus, this paper seeks to examine what will be termed the "Louisiana gothic", a particular blend of fairy-tale timelessness, local color, and the transfiguration of the human. Ultimately, the Louisiana gothic, as expressed in French, English, and Creole, tends toward a view of society in decay, mobilizing these elements of horror and of fairy tales to comment on a society that, after the revolution in Saint-Domingue, the Louisiana Purchase, and the Civil War, was seen as falling into inevitable decline. This commentary on societal decay, expressed through elements of folk horror, sets apart Louisiana gothic as a distinct subgenre that challenges conventions about the structures and functions of the fairy tale.

This paper situates a park commemorating Plaquemines Parish segregationist "Judge" Leander Perez, whose political career spanned from 1919 until his death in 1969, in the changing landscape of post-Civil Rights era white supremacist ambitions. Opened by the parish in 1979, officially closed in 1984, and re-established by residents of a nearby majority-white neighborhood under another name in 2020, the site's uses reflect shifting iterations of white spatial logics oriented toward maintaining power through racialized exclusion (Lipsitz 2007). As a ruin, Leander H. Perez Memorial Park's trajectory contrasts those of nearby plantation manors that were similarly dedicated as heritage sites in the late 1970s. Park brochures, archival newspaper articles, and ethnographic interviews illuminate the ways in which the park's representations of Perez made continuities of the Antebellum plantation racial order too legible for comfort for those who benefited from the political philosophy he represented. I elaborate "commemorative concealment" as a way of recognizing an assortment of practices through which dominant groups in a racial hegemony maintain power by hiding continuities of past exclusions in the heritage landscape.

This paper investigates how and whether speakers of endangered languages employ variation as a stylistic resource to make social meaning and index their identities. The study is set in historically Creole-speaking communities in rural Louisiana, which have now shifted almost completely to English. The Americanization of Louisiana induced language shift, but also a shift to the Anglo-American racial binary which supplanted local constructs of ethnicity and race. The study crafts a historical-sociolinguistic account of this process of Americanization, examining how linguistic differentiation was enacted through the enregisterment of iconic 'Creole'/'French' variants as indexical links to the 'Black'/'White' racial binary. Today, to a very limited extent, some speakers of Louisiana Creole still consider some variants socially meaningful and employ them to stylistic ends. This depends especially on racial identity and the variant in question. Subject pronouns retain some indexical value, occasionally employed stylistically by speakers racialized as White. However, front vowel rounding has fossilized: highly meaningful in the early-20th century, its social meaning has been lost resulting in synchronic personal-pattern variation. The paper ends by trying to reconcile classic studies of Language Death with contemporary variationist critique, answering recent calls for more nuanced approaches to sociolinguistic variation in threatened languages.

Coastal marsh survival relies on the ability to increase elevation and offset sea level rise. It is therefore important to realistically model sediment fluxes between marshes, tidal channels, and bays as sediment availability controls accretion. Traditionally, numerical models have been calibrated and validated using in situ measurements at a few locations within the domain of interest. These datasets typically provide temporal information but lack spatial variability. This paper explores the potential of coupling numerical models with high-resolution remote sensing imagery. Products from three sensors from the NASA Delta-X airborne mission are used. Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) provides vertical water level change on the marshland and was used to adjust the bathymetry and calibrate water fluxes over the marsh. AirSWOT yields water surface elevation within bays, lakes, and channels, and was used to calibrate the Chezy bottom friction coefficient. Finally, imagery from AVIRIS-NG provides maps of total suspended solids (TSS) concentration that were used to calibrate sediment parameters of settling velocity and critical shear stress for erosion. Three numerical models were developed at different locations along coastal Louisiana using Delft3D. The coupling enabled a spatial evaluation of model performance that was not possible using simple point measurements. Overall, the study shows that calibration of numerical models and their general performance will greatly benefit from remote sensing. [ABSTRACT FROM AUTHOR]

This paper reviews the various modes of racist, sexist, classist, ageist, and interspecific oppression as well as occasional transgressions in the city of Bogalusa, Louisiana, as they are dramatized in the poetry of Yusef Komunyakaa, particularly in his 1992 memoirist volume Magic City. More than anything else, Komunyakaa remembers from his childhood days the discourses and practices of violence and control aimed at maintaining a rigid hierarchical structure regulating order between all forms of life and preserving the sense of identity of many. It is a realm of unrelenting terror in which all creatures must succumb to a regime bringing to mind the medieval great chain of being. Komunyakaa investigates thoroughly Southern morals to determine the extent of psychological and epistemic damage they cause. [ABSTRACT FROM AUTHOR]

This paper centres geological matter in questions of marginality, inequality, and structural racism in the US. I follow the entanglements of geological matter with bodies, emotion‐laden imaginaries of place, and histories of slavery and colonialism, to illustrate how contemporary Black lives are intimately connected to processes of mineral extraction. Drawing on Saidiya Hartman's concept of 'afterlives', I situate heightened levels of ambient toxicity from geological refinement and industrial waste as extractive afterlives, connecting commonly felt precarity around extractive worlds to broader questions of race, inequality, and connections to place. Citing academic and artistic accounts of life in Southern Louisiana, a historically Black region with a large petrochemical industry, I demonstrate the relevance of geological entanglements to experiences of structural racism in the US. This paper centres geological matter in questions of marginality, inequality, and structural racism in the US. Following the entanglements of geological matter with bodies, emotion‐laden imaginaries of place, and histories of slavery, I illustrate how contemporary Black lives in Southern Louisiana are intimately connected to processes of mineral extraction through the intimacy of 'extractive afterlives' – the heightened levels of ambient toxicity from geological refinement and industrial waste in the region.

Harmful cyanobacteria blooms (cyanoHABs) are a global phenomenon, especially in calm, warm, and nutrient-rich freshwater and estuarine systems. These blooms can produce various potent toxins responsible for animal poisoning and human health problems. Nutrient-rich freshwater pulsed into estuaries affects turbidity, water temperature, salinity, and nutrient concentrations and ratios at irregular intervals, creating a highly dynamic habitat. However, the underlying processes that lead to the selective development of cyanoHABs for certain species and the fate of their toxins are still uncertain. This paper draws upon the rich body of research available for one such system, the Lake Pontchartrain Estuary, Louisiana, to generate insights about future research directions in pulsed-nutrient-delivery estuaries. Toxin-producing cyanobacteria blooms in river-dominated Louisiana coastal ecosystems have already been documented at high concentrations, presenting a potential risk to human health as $2.4 billion worth of Louisiana's fish and shellfish are consumed by millions of people throughout the US every year. Recent studies have shown that the Lake Pontchartrain Estuary, just north of New Orleans, Louisiana has been experiencing cyanoHABs, likely connected to combinations of (a) high interannual variability in nutrient loading associated with seasonal and episodic rainfall, (b) the timing, duration, and magnitude of the flood-stage Mississippi River water diverted into the Lake Pontchartrain Estuary, and (c) saltwater inputs from tropical storms. It is expected that cyanoHABs will become more frequent in Louisiana with a warming climate and changes to the timing and magnitude of river water diverted into the Lake Pontchartrain Estuary, which will play a dominant role in the development of blooms in this region. More studies are needed to focus on the environmental conditions that control the succession or/and co-existence of different cyanobacteria species and their toxins, optimally culminating in a near-term forecasting tool since this information is critical for health agencies to mitigate or to provide early warnings. Toxin forecasts for pulsed-nutrient estuaries, including Lake Pontchartrain, could directly inform state and municipal health agencies on human exposure risks to upcoming cyanobacteria toxicity events by predicting cyanobacteria species shifts, potency, and toxin modality along the freshwater-to-marine continuum while also informing a longer-term projection on how the changing climate will impact the frequency and potency of such blooms.

Projections indicate that solar energy will constitute 55% of total electricity capacity by 2050 in the US. Despite solar energy's growing importance, few studies have analyzed the risks of countrywide deployments of solar infrastructure due to extreme weather events such as hurricanes. This paper presents a probabilistic framework to evaluate the performance of solar infrastructure to generate energy during hurricanes, which often cause significant outages in the US. Our novel framework integrates recent data-driven models that capture two critical and compounding factors: transient cloud conditions that decrease irradiance and high winds that can cause permanent panel damage. We apply the framework to the 2,694 counties in the 38 central and eastern US states to elucidate the risk landscape of solar generation during hurricanes. Our results show that hurricane impacts are significant, compounding, and strikingly disproportional in the US. We show that in Florida and Louisiana, clouds rapidly reduce solar generation to 32% and 65%, respectively, of their normal levels with a return period of 100 years. Our results also show that damage to panels can induce more acute and permanent energy losses, especially in rarer storms, e.g., causing 80% more losses than hurricane clouds 2 days after landfall for 200-year events.

Understanding the boundary-layer height and its dynamics is crucial for a wide array of applications spanning various fields. Accurate identification of the boundary-layer top contributes to improved air quality predictions, pollutant transport assessments, and enhanced numerical weather prediction through parameterization and assimilation techniques. Despite its significance, defining and observing the boundary-layer top remain challenging. Existing methods of estimating the boundary-layer height encompass radiosonde-based methods, radar-based retrievals, and more. As emerging boundary-layer observation platforms emerge, it is useful to reevaluate the efficacy of existing boundary-layer-top detection methods and explore new ones. This study introduces a fuzzy logic algorithm that leverages the synergy of multiple remote sensing boundary-layer profiling instruments: a Doppler lidar, infrared spectrometer, and microwave radiometer. By harnessing the distinct advantages of each sensing platform, the proposed method enables accurate boundary-layer height estimation both during daytime and nocturnal conditions. The algorithm is benchmarked against radiosonde-derived boundary-layer-top estimates obtained from balloon launches across diverse locations in Wisconsin, Oklahoma, and Louisiana during summer and fall. The findings reveal notable similarities between the results produced by the proposed fuzzy logic algorithm and traditional radiosonde-based approaches. However, this study delves into the nuanced differences in their behavior, providing insightful analyses about the underlying causes of the observed discrepancies. While developed with the three instruments mentioned above, the fuzzy logic boundary-layer-top detection algorithm, called BLISS-FL, could be adapted for other wind and thermodynamic profilers. BLISS-FL is released publicly, fostering collaboration and advancement within the research community. [ABSTRACT FROM AUTHOR]

In the southeastern United States, wood ducks (Aix sponsa) have historically experienced interspecific brood parasitism (IBP) primarily from hooded mergansers (Lophodytes cucullatus), but the recent northward expansion of black-bellied whistling-ducks (Dendrocygna autumnalis) has added a new complexity to these interactions. We monitored nest boxes in Louisiana to evaluate the influence IBP had on wood duck daily nest survival rate (after, DSR) and duckling recruitment. We monitored 1,295 wood duck nests from 2020−2023 and found 112 (8.7%) were parasitized by hooded mergansers and 148 (11.5%) by whistling-ducks. Parasitic egg-laying by hooded mergansers lowered wood duck DSR, while DSR for nests parasitized by whistling-ducks was comparable to clutches containing only wood duck eggs. We considered the wood duck capture histories of 2,465 marked female ducklings and 540 banded adult females to estimate a duckling recruitment probability for the entire study period. We recaptured 50 ducklings as adults; 6 (12.0%) hatched from clutches parasitized by hooded mergansers, 1 (2.0%) from a clutch parasitized by a whistling-duck, and 43 (86.0%) from clutches containing only wood duck eggs. The duckling recruitment probability was 0.039 (95% credible interval = 0.028, 0.051). Nest initiation date had a negative effect on recruitment, wherein most recruits hatched from nests initiated earlier in the season. Given only ~9% of wood duck nests contained hooded merganser eggs, we conclude IBP writ large had no detrimental effect on DSR at a population level. The lower DSR of clutches parasitized by hooded mergansers is potentially linked to a high abundance of early-season parasites that produce "dump nests" and these clutches are often abandoned without being incubated. Despite ongoing parasitism by hooded mergansers and the range expansion of whistling-ducks, wood duck productivity in Louisiana appears to be minimally affected by interspecific brood parasitism.

Objective: Tulane University School of Public Health and Tropical Medicine created a program planning course required for all master of public health (MPH) students to address the revised 2016 Council on Education for Public Health (CEPH) foundational competencies. The objective of this study was to examine students' feedback on this new class based on their reflective writing. Methods: Students across 3 class sections during 3 semesters (fall 2018, spring 2019, and fall 2019) wrote a reflection paper as a final assignment about their course experience (N = 102). We conducted a conventional qualitative content analysis of deidentified student responses to systematically examine themes in the overarching areas of what students found valuable about the course and what they would want to be improved. We calculated frequency counts of themes to further contextualize the findings. Results: Students found the following aspects of the course valuable: a positive perception shift toward program planning (93.1%), new transferable career skills (87.3%), the course format (77.5%), course content (69.6%), working in teams (52.0%), course assignments (47.1%), and the instructional team (31.4%). Critiques included the following: more support for course assignments (39.2%), challenges of working in teams (27.5%), aspects of the course format (25.5%), gaps in course content (19.6%), and wanting more consultations with the instructional team (5.9%). About 14% of students stated there was nothing or little they would change about the course. Conclusion: Overall, the course received positive feedback from students. They identified several valuable course components and areas that could be enhanced, which we have worked to improve. We offer the course as a potential model for how schools and programs of public health can meet the 2016 CEPH competencies. [ABSTRACT FROM AUTHOR]

In the 1950s and 1960s, some Louisiana's bridges were constructed using steel twin-girder or truss systems, in which floorbeams are carried by the main members and continuous (spliced) stringers are supported by the floorbeams. The main members are either two-edge (fascia) girders or trusses. One of the byproducts of this type of design is that stringer bottom flanges are in compression in the negative moment region over the floorbeams, which could result in lateral torsional buckling (LTB) should inadequate lateral bracing be provided. When the continuous stringers are load-rated using AASHTOWare Bridge Rating analysis software (BrR 7.1), their LTB resistance is calculated in accordance with American Association of State Highway Officials (AASHTO) LRFD Bridge Design Specifications, which do not account for potential bracing provided by a noncomposite deck and could underestimate flexural strength. As a result, the rating may be low enough to require restrictive load posting or even bridge closure. This paper summarizes extensive experimental and numerical studies investigating the behavior of this type of floor system by testing two-span, continuous, steel stringers in a grillage that included three stringer lines, an interior transverse support (floorbeam), and transverse diaphragms at the end supports. The tests and finite-element analysis studies encompassed a variety of unbraced lengths and support conditions with steel diaphragms or timber ties acting as bracing members. The findings demonstrated that, for the systems examined, minimal bracing could substantially enhance LTB resistance and supported the use of higher flexural strengths than those currently predicted using AASHTO Specifications. This paper illustrates the use, challenges, and successes in LTB modeling beams with various support and bracing conditions. The most flexible cases were the most difficult to achieve close agreement with experimental results. [ABSTRACT FROM AUTHOR]

The effects of climate change are both acute and chronic, leaving many communities in a perpetual state of uncertainty. For others, there is no such uncertainty—their communities will soon be uninhabitable. Some levels of government have begun to recognize and slowly respond to communities facing the possibilities of relocation. This paper considers the impact of transdisciplinary thinking and collaborative moments in the planning phase of one of the few community‐scale managed retreat attempts in the United States. In January 2016, the US Department of Housing and Urban Development (HUD) awarded the state of Louisiana $48.3 million to plan, design, and implement a structured and scalable resettlement with former and current residents of Isle de Jean Charles. The paper uses data from surveys and interviews with the practitioner team, fieldnotes, review of published reports, and a sample of more than 400 media accounts. Our analysis highlights how developing a transdisciplinary process may render a new understanding to the tasks and meanings of planning resettlements in the future. [ABSTRACT FROM AUTHOR]

Abstract In this paper, I estimate the effect of access to family planning clinics on birth rates. The Louisiana Family Planning Program opened more than 140 clinics between 1965 and 1970. By 1971, a family planning clinic was operating in each Louisiana county. Exploiting the variation in dates when clinics began operating in each county, I employ two-way fixed effects and staggered difference-in-differences designs to assess the impact of family planning access on birth rates. I find that clinic openings led to a 5 to 7 percent decrease in birth rates. [ABSTRACT FROM AUTHOR]

This paper strives to look at various user-centered approaches within information environments as it pertains to colloquial jargon, specifically the use of the words traiteur to describe Cajun faith healers/folk doctors and buaji to describe faith healers of several different faiths in India. Focus groups, multiple constituencies and their differing needs, types of resource, and how this affects libraries and archives specifically in South Louisiana will all be discussed. Also considered will be information-seeking behaviors of two diverse constituencies. This paper will look at a way to circumvent the Library of Congress (LOC) subject headings to allow patrons of libraries and archives to find the information they are searching for in a quick, succinct manner. The usability of the system and the ability of the user to quickly find the information is what is most important in this case. We were successful in adding an LOC subject heading and will also explore how to make sure patrons are able to find the catalog entries so they can spend more time researching the topic by utilizing a different line on the MARC record and creating a LibGuide. This will further help establish the University of Louisiana at Lafayette as the Université des Acadiens. This paper will look at the sources that were located and attempt to synthesize the information in a way that allows the reader a better understanding of not only what exactly a traiteur is, but also why these issues arise and their importance to patrons and library staff alike.

This paper presents damage assessment using a hierarchical transformer architecture (DAHiTrA), a novel deep‐learning model with hierarchical transformers to classify building damages based on satellite images in the aftermath of natural disasters. Satellite imagery provides real‐time and high‐coverage information and offers opportunities to inform large‐scale postdisaster building damage assessment, which is critical for rapid emergency response. In this work, a novel transformer‐based network is proposed for assessing building damage. This network leverages hierarchical spatial features of multiple resolutions and captures the temporal differences in the feature domain after applying a transformer encoder to the spatial features. The proposed network achieves state‐of‐the‐art performance when tested on a large‐scale disaster damage data set (xBD) for building localization and damage classification, as well as on LEVIR‐CD data set for change detection tasks. In addition, this work introduces a new high‐resolution satellite imagery data set, Ida‐BD (related to 2021 Hurricane Ida in Louisiana) for domain adaptation. Further, it demonstrates an approach of using this data set by adapting the model with limited fine‐tuning and hence applying the model to newly damaged areas with scarce data.

Objectives. To assess heterogeneity in pandemic-period excess fatal overdoses in the United States, by location (state, county) and substance type. Methods. We used seasonal autoregressive integrated moving average (SARIMA) models to estimate counterfactual death counts in the scenario that no pandemic had occurred. Such estimates were subtracted from actual death counts to assess the magnitude of pandemic-period excess mortality between March 2020 and August 2021. Results. Nationwide, we estimated 25 668 (95% prediction interval [PI] = 2811, 48 524) excess overdose deaths. Specifically, 17 of 47 states and 197 of 592 counties analyzed had statistically significant excess overdose-related mortality. West Virginia, Louisiana, Tennessee, Kentucky, and New Mexico had the highest rates (20–37 per 100 000). Nationally, there were 5.7 (95% PI = 1.0, 10.4), 3.1 (95% PI = 2.1, 4.2), and 1.4 (95% PI = 0.5, 2.4) excess deaths per 100 000 involving synthetic opioids, psychostimulants, and alcohol, respectively. Conclusions. The steep increase in overdose-related mortality affected primarily the southern and western United States. We identified synthetic opioids and psychostimulants as the main contributors. Public Health Implications. Characterizing overdose-related excess mortality across locations and substance types is critical for optimal allocation of public health resources.

The impact of surface wave assimilation on hurricane track and intensity forecasts has been investigated using a fully coupled air-ocean-wave tropical cyclone data assimilation and forecast modeling system. A new 3DVAR wave assimilation method in the Navy Coupled Ocean Data Assimilation system (NCODA) maps the 1D wave energy spectra from buoys to 2D directional wave energy spectra using the maximum likelihood method (MLM) and corrects the wave model forecast component directional wave energy spectra. The Coupled Ocean/Atmosphere Mesoscale Prediction System for Tropical Cyclone Prediction (COAMPS-TC) is used to conduct three Hurricane Harvey (2017) airocean-wave coupled data assimilation and forecasting experiments with and without the wave data assimilation. Hurricane Harvey traversed through the Western Gulf of Mexico from 24 August to 1 September, 2017 and made landfall in the Texas and Louisiana coast. Validation of track, maximum wind speed, significant wave height, and mean absolute wave periods show wave assimilation of the 1D wave energy spectra from 13 National Data Buoy Center (NDBC) buoys reduced the forecast errors of these parameters compared to experiments without the wave assimilation. In spite of this positive outcome, the wave assimilation is unable to reduce Harvey's 0-120 h forecast mean wave direction errors and correlation compared to the NDBC buoy time series.

A three-dimensional coupled hydrodynamic–biogeochemical model with multiple nutrient and plankton functional groups was developed and adapted to the Gulf of Mexico to investigate the role of nutrients and the complexity of plankton community in dissolved oxygen (DO) dynamics. A 15-year hindcast was achieved covering the period of 2006–2020. Extensive model validation against in situ data demonstrates that the model was capable of reproducing vertical distributions of DO and spatial distributions of bottom DO concentration, as well as their interannual variations. The study demonstrates that bottom DO dynamics and hypoxia evolution are significantly influenced by both physical processes and local biochemistry, with sedimentary oxygen consumption and vertical diffusion identified as key contributors. Summer hydrodynamics play a critical role in nutrient distribution and limitation: a notable expansion of Si limitation was simulated when coastal currents shifted eastward or northward. This effect, especially pronounced on the western part of the Louisiana–Texas shelf, underscores the importance of nutrient limitation in shaping DO dynamics. The model identifies a bi-peak primary production pattern in spring and early summer, aligned with satellite chlorophyll a variations, attributed to the complexity of the plankton community and interactions among different plankton groups. Our findings emphasize the necessity of integrating sophisticated plankton community dynamics into biogeochemical models to understand primary production variability and its impact on bottom hypoxia.

There are different types of equitable estoppel under English law including promissory estoppel, estoppel by convention and proprietary estoppel. In this article the various types of estoppel under English law are considered and the doctrine of proprietary estoppel in the context of the creation of a trust is discussed. The English doctrine of equitable estoppel is compared to the principle of promissory estoppel in United States law, including the superimposition of the Statute of Frauds. Its protection of the principle of equitable estoppel has extended to the mixed jurisdiction of Louisiana which has adopted the civil law remedies which are equivalent and lead to similar outcomes.

The article examines how COVID-19 and the U.S. Supreme Court decision which held that the Constitution does not confer a right to abortion, have impacted abortion services in Louisiana. Cited are studies showing that the state's pandemic abortion ban has disrupted people's ability to obtain abortions, how the Dobbs decision has allowed states not just to restrict abortion but also to ban abortion outright, and the political shift on abortion that is needed at the state or the federal level.

Background: Police violence is increasingly recognized as an urgent public health problem. Basic questions about police violence, however, remain unanswered, including which types of law enforcement agency are responsible for fatal police violence deaths. Methods: We estimated the proportion of police violence deaths in the U.S. (2013–2022) that were attributable to local, county, state, federal, or tribal police agencies, using mapping police violence data. We examined proportions overall, by decedent race/ethnicity, and by state. Results: Nationally, 60% of decedents were killed by municipal, 29% by county, 8% by state, and 3% by federal, police, with < 1% killed by tribal or other officers. These proportions varied by race/ethnicity, with 56% of Native American decedents killed by municipal police compared to 70–75% among other racially minoritized people. While municipal police were responsible for most deaths in most states, in the Southeast, county police predominated. In some Northeastern states (and Alaska), state police were responsible for > 40% of deaths. Conclusions: We identify wide geographic & racial/ethnic variation in the agencies responsible for fatal police violence. Findings suggest that the budgetary and infrastructural shifts required to prevent fatal police violence need to occur at multiple levels of government. [ABSTRACT FROM AUTHOR]

Carbon sequestration in the forests of the eastern United States is an important offset to the country's CO2 emissions. Much of the eastern forestland is the product of reforestation of abandoned agricultural land or recovery following clear‐cutting over a century ago. This has led to concerns that eastern forests are even‐aged and that rates of carbon sequestration will decline as forests increase in carbon. Our objective was to examine the successional dynamics of forest carbon sequestration—using live tree carbon stocks as a proxy for successional status—for the six broadly defined forest types present in the region. We used datasets from the National Forest Inventory (NFI) for the 31 US states from Minnesota south to Louisiana and eastward and analyzed live tree net carbon increment for 2007–2021, the period for which NFI plot remeasurement data were available for all 31 states. Spruce–fir and southern pines were the only forest types for which carbon increment declined even modestly over a significant fraction of the range of live tree carbon observed in the region, and southern pine–hardwood forests were the only forests in which predicted sequestration in live tree carbon declined to zero within the range of carbon stocks observed in the region. Northern hardwood–conifer forests, oak–hickory forests, and lowland forests experienced either no decline or a slight increase in sequestration in live tree carbon across the range of successional status observed in the region. Thus, the average stocks of live tree carbon per unit area increased steadily over the study period. At some point in succession, rates of mortality are expected to increase and balance gross growth, leading to zero net sequestration in live tree carbon. Mature and old‐growth stands, however, are rare in all six forest types, and mortality as a fraction of live tree carbon for all six forest types declined across the range of successional status present in the region. Our results thus provide no support for the hypothesis that the successional dynamics of forests in this region can be expected to lead to near‐term declines in net carbon sequestration.

Mosquitofish, Gambusia affinis, are eponymous larval mosquito predators. Their ability to colonize and survive in habitats that are uninhabitable by other potential predators allows them to naturally manage larval mosquito populations in most ground pools they are present in. However, effluent from residential onsite wastewater treatment systems (OWTSs) appears to limit the presence of fish predators. This is especially problematic in Louisiana, where regulations allow the discharge of OWTS effluent into open drainage conveyances. To determine the effect of effluent on the capacity of mosquitofish for biocontrol in contaminated areas, we assessed the body condition metrics of populations from two effluent-exposed sites and two sites not exposed to effluent, determined the lethal effect of effluent-contaminated drainage water on fish, and measured the prey consumption rates in the presence of effluent. Female fish collected from effluent-impacted sites had a reduced somatic body condition and most females examined displayed masculinized anal fins resembling the male gonopodium structure. This trait was not seen in fish collected from the control sites and has not yet been documented in association with OWTSs or in the state of Louisiana. Fish from the control sites survived at effluent-contaminated water levels < 70%, and the prey clearance rates increased with dilution. Onsite wastewater treatment system effluent has significant effects on both the short- and long-term persistence of mosquitofish, their body composition, reproductive health, and larval mosquito consumption. These effects likely release mosquito larvae from suppression and may increase the threat of mosquito-transmitted pathogens in effluent-contaminated locations. [ABSTRACT FROM AUTHOR]

Variety development of sugarcane (Saccharum spp. hybrids) is necessary to continue improving sugar yields and selecting photosynthetic traits can improve sugar production through increased carbon inputs. In this study, gas exchange and whole-plant measurements were made on 55 sugarcane genotypes in Louisiana. Variation in the relationship between photosynthetic rate and stomatal conductance suggests that sugarcane exhibits variation in both photosynthetic capacity and CO2 substrate availability. Genotypes that reached maximum photosynthetic rate (TRMPR) in the gas-exchange cuvette more quickly had greater CO2 assimilation during transitory periods. Temporary shading and fluctuating light are common transitory conditions in the field, so increasing TRMPR can improve photosynthesis in water-abundant regions. Canopy leaf area was positively correlated with stalk mass, but gas-exchange traits were not correlated with whole-plant traits. A better understanding of the relationship between leaf and whole-plant traits is necessary to identify physiological traits that lead to increased genetic gain. [ABSTRACT FROM AUTHOR]

This paper presents a novel numerical technique for the identification of effective and basic reproduction numbers, R e and R 0 , for long-term epidemics, using an inverse problem approach. The method is based on the direct integration of the SIR (Susceptible–Infectious–Removed) system of ordinary differential equations and the least-squares method. Simulations were conducted using official COVID-19 data for the United States and Canada, and for the states of Georgia, Texas, and Louisiana, for a period of two years and ten months. The results demonstrate the applicability of the method in simulating the dynamics of the epidemic and reveal an interesting relationship between the number of currently infectious individuals and the effective reproduction number, which is a useful tool for predicting the epidemic dynamics. For all conducted experiments, the results show that the local maximum (and minimum) values of the time-dependent effective reproduction number occur approximately three weeks before the local maximum (and minimum) values of the number of currently infectious individuals. This work provides a novel and efficient approach for the identification of time-dependent epidemics parameters. [ABSTRACT FROM AUTHOR]

This paper addresses the social resonances to the complex causes, effects, and feedback of land loss in southern Louisiana, particularly with respect to the region's vulnerability to the impacts of anthropogenic climate change, especially against the backdrop of the consequences and side effects of the resident petrochemical industry. Using empirical findings from an online discussion about coastal land loss and talks to people in Louisiana, the different perceptions of coastal land loss of affected and not-affected people become apparent. As a result of the high complexity of the topic, a meta-theoretical framing by neopragmatism, as well as an analytical framing based on Popper's theory of three worlds, is provided.

Gabriel and the 1800 conspiracy he helped plan in Richmond, Virginia, had reverberations around the Atlantic. A range of historians have explored the ways in which Haiti, France, Spain, Liberia, and even Sierra Leone formed a constellation of influences on, or legacies of, the 1800 plot. This article assesses the fuller transnational context of Gabriel's conspiracy and draws links between its aftermath and concrete plans by Virginia lawmakers to colonize rebellious enslaved peoples and free Blacks in French Louisiana. Two decades before the founding of Liberia, politicians in and from Virginia imagined French Louisiana as a site of Black exile and as a solution to the persistent threat of insurrection. This imagination turned to political lobbying as many of the same lawmakers vexed by the implications of the 1800 plot moved to pressure Thomas Jefferson to purchase Louisiana and to exert direct control over this planned colony of Black exiles.

Natural disasters have large social and economic consequences. However, adequate economic and social data to study subnational economic effects of these negative shocks are typically difficult to obtain especially in low-income countries. For this reason, the use of night light data is becoming increasingly popular in studies which aim to estimate the impacts of natural disasters on local economic activity. However, it is often unclear what observed changes in night lights represent exactly. In this paper, we examine how changes in night light emissions following a severe hurricane relate with local population, employment, and income statistics. We do so for the case of Hurricane Katrina, which struck the coastline of Louisiana and Mississippi in August 2005. Hurricane Katrina is an excellent case for this purpose as it is one of the biggest hurricanes in recent history in terms of human and economic impacts, it made landfall in a country with high-quality sub-national socioeconomic data collection, and it is covered extensively in the academic literature. We find that overall night light changes reflect the general pattern of direct impacts of Katrina as well as indirect impacts and subsequent population and economic recovery. Our results suggest that change in light intensity is mostly reflective of changes in resident population and the total number of employed people within the affected area and less so but positively related to aggregate income and real GDP.

According to the Institute for Women’s Policy, women in the United States working in the state of Louisiana earn sixty-nine cents on the dollar compared to their male counterparts. This is a substantial discrepancy and has been used as a call for action. However, what is really behind this variance in pay between women and men? For a large part, it is the types of careers that men and women choose to enter. A more valid comparison between men’s and women’s pay is to look at pay differences within the same chosen career path. This study looks at faculty pay at a regional university to ascertain whether there is evidence of a difference in pay between women and men in academia. This paper’s results show that once the area of specialty, rank, and years of experience are considered, male faculty actually, on average, earn less than their female counterparts.

Coastal marsh survival relies upon to their ability to increase their elevation and offset sea level rise. It is therefore fundamental to realistically model the sediment fluxes between marshes, tidal channels and bays. Traditionally, numerical models have been calibrated and validated using in-situ measurements located in few locations within the domain of interest. These datasets typically provide temporal information but lack spatial variability. This paper explores the potential of coupling numerical models with high resolution remote sensing imagery. Products from three sensors from the recent NASA DeltaX airborne mission are used. UAVSAR provides vertical water level change on the marshland, and was used to adjust the bathymetry and calibrate the water fluxes over the marsh. AirSWOT yields water surface elevation within bays, lakes and channels and was used to calibrate the Chezy bottom friction coefficient. Finally, imagery from AVIRIS-NG provide maps of total suspended solids (TSS) concentration that were used to calibrate sediment parameters of settling velocity and critical shear stress for erosion. Three numerical models were developed at different locations and scales along coastal Louisiana using Delft3D. The coupling enabled a spatial evaluation of model performance not possible using simple point measurements. Some limitations were highlighted in the remote sensing imagery and the numerical models that need to be accounted for when comparing the results. Overall, the study shows that calibration of numerical models and their general quality will greatly benefit from remote sensing. [ABSTRACT FROM AUTHOR]

In this paper, I analyse the representation of reported discourse in testimony from a 1795 conspiracy trial. I present a framework for analysing scribal intervention in discourse reporting and show that, although the transcription conventions of historical criminal proceedings offer the appearance of being objective representations, recorded testimony privileges idealised representations of speech events. In fact, a special status is given to those speech events to which those in the courtroom were not privy, that is, hearsay. When scribes use Direct Discourse to report this type of speech, they are simultaneously marking it as evidence available for judicial decision-making and distancing themselves from the judgment and interpretation process. I show that this is particularly problematic for interpreted testimony. This has implications for both our understanding of historical courtroom processes and the use of trial transcripts for historical sociolinguistic and pragmatic analysis. [ABSTRACT FROM AUTHOR]

The effectiveness of regional storm surge reduction strategies and tank-level structural mitigation measures in reducing the failure probability of aboveground storage tanks (ASTs) were studied. Given past failures during flood and hurricane events, several studies have developed fragility models for ASTs. However, the suitability of these fragility models for different hurricane hazard scenarios is unknown. Furthermore, to combat climate change and sea level rise, several regional storm surge reduction strategies are being proposed. However, the effectiveness of these strategies in improving the safety of ASTs is also unknown. So, herein, a framework was proposed that facilitates assessing the suitability of fragility models and the quantification of AST failures and their consequences while propagating uncertainties using Monte Carlo simulations. The application of the proposed framework to Cameron, Louisiana, provided several key insights: (1) fragility models that do not model wave loads and dislocation failure are not suitable for the region; (2) a regional risk mitigation strategy was insufficient for lowering future spill volume, repair, and cleanup costs; and (3) considering bottom-plate failure of anchored tanks—a structural risk mitigation measure—would lead to a 47–72% reduction in the consequences of tank failure.

Governments use metrics made possible by new data technologies to allocate budgets, manage pandemics, valorize ecosystems, and demonstrate how these actions are legitimate. Big data is pointed to as providing objective answers that emerge untampered from observations of the world as it is – a view from nowhere. While data is more valued than ever in environmental governance, so too are arrangements that seek stakeholders' input and otherwise address their subjective interests – a view from everywhere. Different kinds of metrics perform state actors as accountable in both registers: metrics that are responsive to dynamic conditions; that account for specific stakeholders; that can be prioritized against one another in interactive data visualization tools. Louisiana, USA's Coastal Master Plan is an attempt to stem wetlands loss through fine-scale modeling of large volumes of data and calculation of these kinds of social and environmental metrics. State actors there make accountability claims that appear contradictory: their decisions are legitimate because they are driven by the best available coastal science and technology, while their data tools 'didn't make decisions for us.' As state actors deploy environmental big data and metrics to make sense of it, we should be able to explain these apparently contradictory stances and the controversies that result. STS theory on metrics in environmental governance benefits from characterizing how 'modes of authorized seeing' are given expression by different metrical forms and what brings modes into contact and conflict.
