Mass Concentration And Size Distribution Of Particles Released From Harvesting And Biomass Burning Of Sugarcane, Sanku Dattamudi, Jim J. Wang, Syam K. Dodla, Ronald Delaune, April Hiscox, Howard Viator, Changyoon Jeong Jan 2020

Mass Concentration And Size Distribution Of Particles Released From Harvesting And Biomass Burning Of Sugarcane, Sanku Dattamudi, Jim J. Wang, Syam K. Dodla, Ronald Delaune, April Hiscox, Howard Viator, Changyoon Jeong

Faculty Publications

We evaluated size distribution and mass concentrations of fine (particulate matter < 2.5 μm, PM2.5) and coarse (particulate matter = 2.5–10 μm, PM2.5-10) particles released during sugarcane (Saccharum spp.) harvesting operations, including cutting of green cane (GH), burning of standing cane (SB), cane harvest cutting after SB (BH), and ground burning of harvest residues left in the field (GB). Total number of PM2.5 released from GB was 1.63 times greater than that from SB. Total time of burning (flaming + smoldering) phase during GB was 1.5 to 2.1 times longer than SB. The flaming phase for both GB and SB was shorter than the smoldering phase but emitted 5.2 to 7.5 times more PM2.5. Average particle density of PM2.5 from burning operations was 1.12 g cm−3 for GB and 0.52 g cm−3 for SB. The GH and BH released lower PM2.5 but higher PM2.5-10 as compared to SB and GB. Overall, biomass burning, regardless GB and SB difference, released significantly higher PM2.5 than harvest-cutting operations.

Distributive Justice And Rural America, Ann M. Eisenberg Jan 2020

Distributive Justice And Rural America, Ann M. Eisenberg

Faculty Publications

Today’s discourse on struggling rural communities insists they are “dying” or “forgotten.” Many point to globalization and automation as the culprits that made livelihoods in agriculture, natural resource extraction, and manufacturing obsolete, fueling social problems such as the opioid crisis. This narrative fails to offer a path forward; the status quo is no one’s fault, and this “natural” rural death inspires mourning rather than resuscitation. This Article offers a more illuminating account of the rural story, told through the lens of distributive justice principles. The Article argues that rural communities have not just “died.” They were sacrificed. Specifically, distributive justice …

A Multi-Stage Machine Learning Approach To Predict Dengue Incidence: A Case Study In Mexico, Annalisa Appice, Yulia R. Gel, Iliyan Iliev, Vyacheslav Lyubchich, Donato Malerba Jan 2020

A Multi-Stage Machine Learning Approach To Predict Dengue Incidence: A Case Study In Mexico, Annalisa Appice, Yulia R. Gel, Iliyan Iliev, Vyacheslav Lyubchich, Donato Malerba

Faculty Publications

© 2013 IEEE. The mosquito-borne dengue fever is a major public health problem in tropical countries, where it is strongly conditioned by climate factors such as temperature. In this paper, we formulate a holistic machine learning strategy to analyze the temporal dynamics of temperature and dengue data and use this knowledge to produce accurate predictions of dengue, based on temperature on an annual scale. The temporal dynamics are extracted from historical data by utilizing a novel multi-stage combination of auto-encoding, window-based data representation and trend-based temporal clustering. The prediction is performed with a trend association-based nearest neighbour predictor. The effectiveness …

Mass Seizure And Mass Search, Gregory Brazeal Jan 2020

Mass Seizure And Mass Search, Gregory Brazeal

Faculty Publications

As courts attempt to develop Fourth Amendment doctrine to address the threats to privacy created by digital surveillance technologies, a valuable doctrinal resource has been largely neglected: the law governing the seizure of persons. Just as courts today struggle with the specter of mass search using digital technologies, courts in the 1960s were confronted with the problem of mass seizure through the growing use of stop-and-frisk by police departments. The responses to mass seizure developed by the Supreme Court in Terry v. Ohio, 592 U.S. 1 (1968), and its progeny provide lessons for courts today considering how to respond to …

Liquidating Elector Discretion, Rebecca Green Jan 2020

Liquidating Elector Discretion, Rebecca Green

Faculty Publications

In Chiafalo et al. v. Washington, the US. Supreme Court determined that states may constitutionally remove or punish faithless electors. In support of its holding, the Court cited a 2014 case called National Labor Relations Board v. Noel Canning, which blessed a form of constitutional interpretation that looks to settled practice (or "liquidation," as James Madison called it) to resolve constitutional ambiguity. The Court agreed with petitioners that electors following the majority will of voters in their state is settled practice. This Article engages this assertion, suggesting that the question is more nuanced than the Court allowed. It …

Real Effects Of Search Frictions In Consumer Credit Markets, Bronson Argyle, Taylor Nadauld, Christopher Palmer Jan 2020

Real Effects Of Search Frictions In Consumer Credit Markets, Bronson Argyle, Taylor Nadauld, Christopher Palmer

Faculty Publications

We establish two underappreciated facts about costly search. First, unless demand is perfectly inelastic, search frictions can result in significant deadweight loss by decreasing consumption. Second, whenever cross-price elasticities are non-zero, costly search in one market also affects quantities in other markets. As predicted by our model of search for credit under elastic demand, we show that search frictions in credit markets contribute to price dispersion, affect loan sizes, and decrease final-goods consumption. Using microdata from millions of auto-loan applications and originations not intermediated by car dealers, we isolate plausibly exogenous variation in interest rates due to institution-specific pricing rules …

“In The Beginning, It Was Little Whispers...Now, We’Re Almost A Roar”: Conceptualizing A Model For Community And Self In Lgbtq+ Health Information Practices, Vanessa Kitzie, Travis L. Wagner, Alexander N. Vera

Faculty Publications

Although LGBTQ+ populations experience significant health challenges, little research exists that investigates their health from an informational perspective. Our study addresses this gap by exploring the health information practices of LGBTQ+ communities in South Carolina, focusing on how sociocultural context shapes these practices. Thirty semi-structured interviews with South Carolina LGBTQ+ community leaders analyzed using open qualitative coding informed the development of a conceptual framework describing their information practices. Findings show that participants engaged in two broad types of practices – protective and defensive – as responses to risks and barriers experienced, which are in turn produced by social and structural …

The Isaiah Map: An Approach To Teaching Isaiah, John Hilton Iii Jan 2020

The Isaiah Map: An Approach To Teaching Isaiah, John Hilton Iii

Faculty Publications

I saiah is an extremely important prophet—his words were endorsed by the Savior himself (see 3 Nephi 23:1). Because Isaiah’s words can be difficult to comprehend, religious educators have a significant responsibility to help their students understand them. Perhaps the best opportunity to teach Isaiah in a Sunday School, seminary, or institute setting is during a course in the Old Testament. The next best opportunity is when teaching the Book of Mormon. “Nineteen of Isaiah’s sixty-six chapters are quoted in their entirety in the Book of Mormon and, except for two verses, two other chapters are completely quoted. Of the …

Chapter 7: Applied Rhetoric As Disciplinary Umbrella: Community, Connections, And Identity, Jacob D. Rawlins Jan 2020

Chapter 7: Applied Rhetoric As Disciplinary Umbrella: Community, Connections, And Identity, Jacob D. Rawlins

Faculty Publications

: This chapter argues that many of the existing names and boundaries in use around professional communication create artificial separations among research, pedagogy, theory, and action related to the practice of rhetoric in contemporary society. Scholars working in this area teach and conduct research across a variety of disciplines, but we share a rhetorical foundation and a concern for the practical application of that theory. This combination of classical rhetoric and public action provides a way to move our work beyond the confines of the academy and actively engage in rhetorical work within the communities where we work, live, and …

Multilevel Analysis In Rural Cancer Control: A Conceptual Framework And Methodological Implications, Whitney Zahnd, Sara L. Mclafferty, Jan M. Eberth Dec 2019

Multilevel Analysis In Rural Cancer Control: A Conceptual Framework And Methodological Implications, Whitney Zahnd, Sara L. Mclafferty, Jan M. Eberth

Faculty Publications

Rural populations experience a myriad of cancer disparities ranging from lower screening rates to higher cancer mortality rates. These disparities are due in part to individual-level characteristics like age and insurance status, but the physical and social context of rural residence also plays a role. Our objective was two-fold: 1) to develop a multilevel conceptual framework describing how rural residence and relevant micro, macro, and supra-macro factors can be considered in evaluating disparities across the cancer control continuum and 2) to outline the unique considerations of multilevel statistical modeling in rural cancer research. We drew upon several formative frameworks that …

Morphologic Adjustments Of Actively Evolving Highly Curved Neck Cutoffs, Derek Richards, Kory Konsoer Dec 2019

Morphologic Adjustments Of Actively Evolving Highly Curved Neck Cutoffs, Derek Richards, Kory Konsoer

Faculty Publications

Neck cutoffs and their resultant oxbow lakes are important and prominent features of riverine landscapes. Detailed field-based research focusing on the morphologic evolution of neck cutoffs is currently insufficient to fully characterize cutoff evolution. High-resolution bathymetric data were collected over 3 years for the purpose of determining channel morphology and morphologic change on three actively evolving neck cutoffs. Results indicate the following general trends in morphologic adjustment: (1) a longitudinal bar in the upstream meander limb that develops near the entrance to the abandoned bend; (2) a deep scour hole in the downstream meander limb immediately downstream of the cutoff …

The Case For Hyrcanus Ii As The “Wicked Priest” And A Pirate: Evidence From Neglected Roman Historical Sources, Kenneth Atkinson Dec 2019

The Case For Hyrcanus Ii As The “Wicked Priest” And A Pirate: Evidence From Neglected Roman Historical Sources, Kenneth Atkinson

Faculty Publications

Scholars have long debated the identity of the mysterious person denounced in the Dead Sea Scrolls by the sobriquet the Wicked Priest (הכוהן הרשע). Since the discovery of the Scrolls, researchers have identified nearly twenty persons as the Wicked Priest. Some view this vast number of proposals as indicative of a faulty method for understanding the history of the community behind these texts. This is because such efforts assume the Wicked Priest was an actual person. Consequently, scholars seeking to uncover his identity use material from Josephus, Philo, Pliny, and other writers to interpret the references to him in the …

© 2019 The Author(s). Background: Baboons (genus Papio) and geladas (Theropithecus gelada) are now generally recognized as close phylogenetic relatives, though morphologically quite distinct and generally classified in separate genera. Primate specific Alu retrotransposons are well-established genomic markers for the study of phylogenetic and population genetic relationships. We previously reported a computational reconstruction of Papio phylogeny using large-scale whole genome sequence (WGS) analysis of Alu insertion polymorphisms. Recently, high coverage WGS was generated for Theropithecus gelada. The objective of this study was to apply the high-Throughput "poly-Detect" method to computationally determine the number of Alu insertion polymorphisms shared by T. …

emperatures (SST), salinity, carbonate chemistry, and acidity. Over the last half-century, some reef communities have been disappearing at an alarming pace. This study focuses on the Gulf of Mexico, where the majority of shallow coral reefs are reported to be in poor or fair condition. We analyze the RCP8.5 ensemble of the Community Earth System Model v1.2 to identify monthly-to-decadal trends in Gulf of Mexico SST. Secondly, we examine projected changes in ocean pH, carbonate saturation state, and salinity in the same coupled model simulations. We find that the joint impacts of predicted higher temperatures and changes in ocean acidification …

Testing Predictability Of Disease Outbreaks With A Simple Model Of Pathogen Biogeography, Tad Dallas, Colin J. Carlson, Timothée Poisot Nov 2019

Testing Predictability Of Disease Outbreaks With A Simple Model Of Pathogen Biogeography, Tad Dallas, Colin J. Carlson, Timothée Poisot

Faculty Publications

Predicting disease emergence and outbreak events is a critical task for public health professionals and epidemiologists. Advances in global disease surveillance are increasingly generating datasets that are worth more than their component parts for prediction-oriented work. Here, we use a trait-free approach which leverages information on the global community of human infectious diseases to predict the biogeography of pathogens through time. Our approach takes pairwise dissimilarities between countries’ pathogen communities and pathogens’ geographical distributions and uses these to predict country–pathogen associations. We compare the success rates of our model for predicting pathogen outbreak, emergence and re-emergence potential as a function …

Integrating Geochronologic And Instrumental Approaches Across The Bengal Basin, Carol Wilson

Faculty Publications

Constraining time is of critical importance to evaluating the rates and relative contributions of processes driving landscape change in sedimentary basins. The geomorphic character of the field setting guides the application of geochronologic or instrumental tools to this problem, because the viability of methods can be highly influenced by geomorphic attributes. For example, sediment yield and the linked potential for organic preservation may govern the usefulness of radiocarbon dating. Similarly, the rate of sediment transport from source to sink may determine the maturity and/or light exposure of mineral grains arriving in the delta and thus the feasibility of luminescence dating. …
