Lignin Chemistry Of Wetland Soil Profiles In Two Contrasting Basins Of The Louisiana Gulf Coast, Weiyang Bi, J. J. Wang, Syam K. Dodla, Lewis A. Gaston, Ronald D. Delaune

Faculty Publications

Recent studies indicate that loss of soil organic matter (SOM) from coastal wetlands can contribute to the hypoxia in the northern Gulf of Mexico along the Louisiana coast. In this study, coastal marsh soil profiles of two contrasting basins were investigated for lignin composition in order to assess organic matter source and degradation status under these different wetland formations. The Atchafalaya Basin is undergoing land building whereas the Barataria Basin is experiencing land loss. Lignin monomers were extracted using alkaline CuO oxidation followed by gas chromatography–mass spectrometry characterization. Marsh soil profiles from the Barataria Basin showed strong lignin storage with …

Although genotyping-by-sequencing (GBS) is a well-established marker technology in diploids, the development of best practices for tetraploid species is a topic of current research. We determined the theoretical relationship between read depth and the phred-scaled probability of genotype misclassification conditioned on the true genotype, which we call expected genotype quality (EGQ). If the GBS method has 0.5% allelic error, then 17 reads are needed to classify simplex tetraploids as heterozygous with 95% accuracy (EGQ = 13) vs. 61 reads to determine allele dosage. We developed an R script to convert tetraploid GBS data in variant call format (VCF) into diploidized …

For doubled haploid (DH) production in maize, F1 generation has been the most frequently used for haploid induction due to facility in the process. However, using F2 generation would be a good alternative to increase genetic variability owing to the additional recombination in meiosis. Our goals were to compare the effect of F1 and F2 generations on DH production in tropical germplasm, evaluating the R1-navajo expression in seeds, the working steps of the methodology, and the genetic variability of the DH lines obtained. Sources germplasm in F1 and F2 generations were crossed with the tropicalized haploid inducer LI-ESALQ. After harvest, …


Information Asymmetry And The Protection Of Ordinary Investors, Kevin S. Haeberle Nov 2019

Information Asymmetry And The Protection Of Ordinary Investors, Kevin S. Haeberle

Faculty Publications

To some, the reductions in information asymmetry provided by the main securities-specific disclosure, fraud, and insider-trading laws help ordinary investors in meaningful ways. To others, whatever their larger social value, such reductions do little, if anything for these investors. For decades, these two sides of this investor-protection divide have mostly talked past each other.

This Article builds on economic theory to reveal something striking: The reductions in information asymmetry provided by the core securities laws likely impose a long-overlooked cost on buy-and-hold ordinary investors. More specifically, I explain why there is much reason to believe that the reductions take away …

The Sun's connection with the Earth's magnetic field and atmosphere is carried out through the exchange of electromagnetic and mass flux and is regulated by a complex interconnection of processes. During space weather events, solar flares, or fast streams of solar atmosphere strongly disturb the Earth's environment. Often the electric currents that connect the different parts of the Sun-Earth system become unstable and explosively release the stored electromagnetic energy in one of the more dramatic expressions of space weather—the geomagnetic storm and substorm. Some aspects of the magnetosphere-ionosphere connection that generates auroral arcs during space weather events are well-known. However, …


The Empower Action Model: A Framework For Preventing Adverse Childhood Experiences By Promoting Health, Equity, And Well-Being Across The Life Span, Aditi Srivastav, Melissa Strompolis, Amy Moseley, Kelsay Shania Daniels Nov 2019

The Empower Action Model: A Framework For Preventing Adverse Childhood Experiences By Promoting Health, Equity, And Well-Being Across The Life Span, Aditi Srivastav, Melissa Strompolis, Amy Moseley, Kelsay Shania Daniels

Faculty Publications

The empower action model addresses childhood adversity as a root cause of disease by building resilience across multiple levels of influence to promote health, equity, and well-being. The model builds on the current evidence around adverse childhood experiences and merges important frameworks within key areas of public health—the socio-ecological model, protective factors, race equity and inclusion, and the life course perspective. The socio-ecological model is used as the foundation for this model to highlight the multilevel approach needed for improvement in public health. Five key principles that build on the protective factors literature are developed to be applied at each …

A Political Interpretation Of Vagueness Doctrine, Brenner M. Fissell, Guyora Binder Nov 2019

A Political Interpretation Of Vagueness Doctrine, Brenner M. Fissell, Guyora Binder

Faculty Publications

The “void-for-vagueness” doctrine requires the specific definition of criminal offenses. In this Article, though, we claim it does more: it largely restricts criminalization decisions to legislatures, which are unlikely to criminalize conduct they see as both harmless and widespread. Thus, rather than constitutionalizing the harm principle and thereby assuming a judicial obligation to define harm, the Supreme Court has used the vagueness doctrine to constrain majorities to make their own assessments of harmfulness. While American law has no explicit requirements that criminal liability be created by legislation or conditioned on harm, the vagueness doctrine achieves those ends indirectly

Late Pleistocene Site Formation And Paleoclimate At Lapa Do Picareiro, Portugal, Michael M. Benedetti, Jonathan A. Haws, Nuno F. Bicho, Lukas Friedl, Brooks B. Ellwood

Faculty Publications

© 2019 Wiley Periodicals, Inc. The cave site of Lapa do Picareiro, Portugal contains a deep (~10 m) sedimentary sequence representing much of the Middle and Upper Paleolithic, with abundant animal bones, lithic/bone/shell artifacts, and charcoal/ash in hearths. A deposition model based on 49 radiocarbon ages demonstrates average sedimentation rates of 0.1–0.3 mm a −1 between 9 and 45 ka. Extrapolation suggests an age at the base of the excavation of 65–78 ka. The cave sediments are primarily limestone éboulis derived from roof spalling, and muddy fine sediment derived from weathered soil infiltrating through bedrock joints and crevices. Bone preservation …

Scheduling Optimization Of Parallel Linear Algebra Algorithms Using Supervised Learning, Gabriel Laberge, Shahrzad Shirzad, Patrick Diehl, Hartmut Kaiser, Serge Prudhomme, Adrian S. Lemoine Nov 2019

Scheduling Optimization Of Parallel Linear Algebra Algorithms Using Supervised Learning, Gabriel Laberge, Shahrzad Shirzad, Patrick Diehl, Hartmut Kaiser, Serge Prudhomme, Adrian S. Lemoine

Faculty Publications

Linear algebra algorithms are used widely in a variety of domains, e.g machine learning, numerical physics and video games graphics. For all these applications, loop-level parallelism is required to achieve high performance. However, finding the optimal way to schedule the workload between threads is a non-trivial problem because it depends on the structure of the algorithm being parallelized and the hardware the executable is run on. In the realm of Asynchronous Many Task runtime systems, a key aspect of the scheduling problem is predicting the proper chunk-size, where the chunk-size is defined as the number of iterations of a for-loop …


Adaptive-Hybrid Redundancy With Error Injection, Nicholas S. Hamilton, Scott R. Graham, Timothy Carbino, James C. Petrosky, J. Addison Betances Nov 2019

Adaptive-Hybrid Redundancy With Error Injection, Nicholas S. Hamilton, Scott R. Graham, Timothy Carbino, James C. Petrosky, J. Addison Betances

Faculty Publications

Adaptive-Hybrid Redundancy (AHR) shows promise as a method to allow flexibility when selecting between processing speed and energy efficiency while maintaining a level of error mitigation in space radiation environments. Whereas previous work demonstrated AHR’s feasibility in an error free environment, this work analyzes AHR performance in the presence of errors. Errors are deliberately injected into AHR at specific times in the processing chain to demonstrate best and worst case performance impacts. This analysis demonstrates that AHR provides flexibility in processing speed and energy efficiency in the presence of errors

Combat And Trajectories Of Physical Health Functioning In Us Service Members, Ben Porter, George A. Bonanno, Paul D. Bliese, Christopher J. Philips, Susan P. Proctor

Faculty Publications

Introduction

Previous research has demonstrated that different forms of mental health trajectories can be observed in service members, and that these trajectories are related to combat. However, limited research has examined this phenomenon in relation to physical health. This study aims to determine how combat exposure relates to trajectories of physical health functioning in U.S. service members.

Methods

This study included 11,950 Millennium Cohort Study participants who had an index deployment between 2001 and 2005. Self-reported physical health functioning was obtained 5 times between 2001 and 2016 (analyzed in 2017), and latent growth mixture modeling was used to identify longitudinal …

Measurement Of Electron Density And Temperature From Laser-Induced Nitrogen Plasma At Elevated Pressure (1–6 Bar), Ashwin P. Rao, Mark Gragston, Anil K. Patnaik, Paul S. Hsu, Michael B. Shattan

Faculty Publications

Laser-induced plasmas experience Stark broadening and shifts of spectral lines carrying spectral signatures of plasma properties. In this paper, we report time-resolved Stark broadening measurements of a nitrogen triplet emission line at 1–6 bar ambient pressure in a pure nitrogen cell. Electron densities are calculated using the Stark broadening for different pressure conditions, which are shown to linearly increase with pressure. Additionally, using a Boltzmann fit for the triplet, the electron temperature is calculated and shown to decrease with increasing pressure. The rate of plasma cooling is observed to increase with pressure. The reported Stark broadening based plasma diagnostics in …

Background: Evidence remains equivocal regarding the association of inflammation, a precursor to cardiovascular disease, and acute exposures to ambient air pollution from traffic-related particulate matter. Though youth with type 1 diabetes are at higher risk for cardiovascular disease, the relationship of inflammation and ambient air pollution exposures in this population has received little attention.

Objectives: Using five geographically diverse US sites from the racially- and ethnically-diverse SEARCH for Diabetes in Youth Cohort, we examined the relationship of acute exposures to PM2.5 mass, Atmospheric Dispersion Modeling System (ADMS)-Roads traffic-related PM concentrations near roadways, and elemental carbon (EC) with biomarkers of inflammation …

Development And Psychometric Properties Of A Prostate Cancer Knowledge Scale For African American Men, Otis L. Owens, Abbas Tavakoli Drph, Theda Rose, Nikki R. Wooten

Faculty Publications

African American men have the highest prostate cancer-related mortality nationally. In response to this disparity, targeted interventions are emerging to enhance African American men's prostate cancer (PrCA) knowledge to ensure they are equipped to make informed decisions about PrCA screening with health-care providers. African American men's PrCA knowledge has been measured inconsistently over time with limited psychometric evidence. The factor structure of this construct in African American men is relatively unknown. This study describes the development and psychometric evaluation of an 18-item Prostate Cancer Knowledge Scale among 352 African American men. Exploratory factor analysis (EFA) was conducted using weighted least …


Legal Systems And The Financing Of Working Capital, Michael Troilo, Brian Walkup, Masato Abe, Seulki Lee Nov 2019

Legal Systems And The Financing Of Working Capital, Michael Troilo, Brian Walkup, Masato Abe, Seulki Lee

Faculty Publications

This study builds on the existing law and finance literature by analyzing the impact of legal systems on both the level and the sourcing of working capital. We find that stronger rule of law results in lower levels of working capital, less sourcing from retained earnings, and more sourcing from banks. Firms in common-law regimes have lower levels of working capital and finance it from banks, while firms from civil-law environments rely on retained earnings and other financial institutions for sourcing. The impact of legal origin on both the level and the sourcing of working capital is mixed.

Innovative Accounting Interviewing: A Comparison Of Real And Virtual Accounting Interviewers, Matthew D. Pickard, Ryan Schuetzler, Joseph S. Valacich, David A. Wood

Faculty Publications

Recent technological advances have made it possible to create automated, virtual interviewers, called embodied conversational agents (ECAs). We study how an ECA compares to a human interviewer in three experiments. In experiment 1, we show that two theoretically motivated factors—making the ECA facially and vocally similar to the interviewee—result in the ECA performing similarly to or better than human interviewers for six antecedents of disclosure quality. In two additional experiments, we show that employees are on average between 21 and 32 percent more likely to disclose violating internal controls to an ECA than to a human interviewer, even if the …

Impact Of Hydration Status On Electromyography And Ratings Of Perceived Exertion During The Vertical Jump, Paul T. Donahue, Samuel J. Wilson, Charles C. Williams, Melinda Valliant, John C. Garner

Faculty Publications

Background: The vertical jumping task is commonly used to assess lower-body power output in athletic populations, in addition to being commonly used to during investigations of hydration and anaerobic performance. Changes in neuromuscular function during a hypohydrated state have been proposed as a potential mechanism to decreases in anaerobic performance.

Objectives: The primary purpose of this investigation was to examine the impact of hydration state on electromyography during the vertical jumping task.

Methods: Twenty recreationally trained males were tested in three hydration conditions (hypohydrated, euhydrated, and control). Testing included maximal voluntary contractions of the vastus lateralis, vastus …

A Private Enforcement Remedy For Information Misuse, Peter Ormerod Oct 2019

A Private Enforcement Remedy For Information Misuse, Peter Ormerod

Faculty Publications

Misuse of users’ personally identifiable information is persistent and pervasive. This Article addresses two questions: why is information misuse so common and so severe and how could domestic law change to make it less so? I use a simple model to illustrate that companies externalize information misuse costs onto users, which has two related but distinct effects: chronic underinvest- ment in information security and excessive retention of user data. I then seize on this observation to propose a specific legal vehicle at the heart of this Article—a private enforcement remedy. This private enforcement remedy has four essential features. First, the …

Copyright © 2019 The Authors, The East Asian monsoon plays an integral role in human society, yet its geological history and controlling processes are poorly understood. Using a general circulation model and geological data, we explore the drivers controlling the evolution of the monsoon system over the past 150 million years. In contrast to previous work, we find that the monsoon is controlled primarily by changes in paleogeography, with little influence from atmospheric CO2. We associate increased precipitation since the Late Cretaceous with the gradual uplift of the Himalayan-Tibetan region, transitioning from an ITCZ-dominated monsoon to a sea breeze–dominated monsoon. …
