The fall armyworm (FAW), Spodoptera frugiperda (JE Smith, 1797), is a serious pest of several crops, particularly maize and other cereals. It has long been known as a pest in the Americas and has invaded most of Africa and parts of the Middle East, Asia, and Australia in the last six years. Its new status as an invasive species causing serious damage in many regions worldwide has highlighted the need for better understanding and has generated much research. In this article, we provide a comprehensive review of FAW covering its (i) taxonomy, biology, ecology, genomics, and microbiome, (ii) worldwide status …

Knowing Him By Heart: African Americans On Abraham Lincoln, Lucas E. Morel

Civil War Book Review

Black American’s attitudes toward the Great Emancipator is the focus of Knowing Him by Heart: African Americans on Abraham Lincoln (University of Illinois Press), edited by Fred Lee Hord and Matthew D. Norman. The essays show that African Americans’ attitudes toward Lincoln “plumb deeper than his reputation as the Great Emancipator,” writes Morel. Indeed, African Americans; attitudes toward Lincoln from his presidency to the recent past evince a “’persistent ambivalence,’” write Hord and Norman in their introduction. Morel believes that “the value of a book about Black American opinions of Lincoln resides not only in the neglected history it tells, …

Grant At 200: Reconsidering The Life And Legacy Of Ulysses S. Grant, Richard G. Mannion

Civil War Book Review

"As [Chris] Scaturro has suggested for years, the name Ulysses S. Grant indeed belongs in the Pantheon with the other greatest of American heroes. What had been written in his name for so long is a historical disgrace and a sad commentary of that bygone historical community. His 'reputational renaissance' is long overdue, and this piece of literature is just one more recent convincing development that will allow Grant to earn his just do."

Sarawak is Malaysia’s largest state, covering most of northern Borneo. It has a remarkable history of scientific bird study, starting in the 1840s and growing ever since. To set the stage for the gazetteer, which is the core of this paper, we start with a review of this history and discuss various forces that have influenced the direction of bird research in the state. Following this introduction comes the gazetteer, which is an annotated list of c. 865 sites in Sarawak where birds have been collected, studied, or regularly observed. The gazetteer provides the latitude, longitude, and elevation of each …

Louisiana Agriculture Magazine, Winter 2023

Louisiana Agriculture

Agricultural best management practices are measures that producers can take to reduce — or eliminate — farming byproducts that enter streams and groundwater. Many of these practices address fertilizer and irrigation management and the handling of pesticides and animal waste. LSU AgCenter research has helped establish these practices, and extension agents assist producers in implementing them.

This issue of Louisiana Agriculture highlights the best management practices for many of the state’s most production areas. Aquaculture specialists detail how crawfish farms can save money while meeting best management practices, and sugarcane experts tell how the AgCenter is developing new varieties to …

Modern-Day Neanderthal Genetic Lifewriting, Interspecies Romance, And The Promise Of Multispecies Autoethnography, Travis Brisini

Faculty Publications

Advances in contemporary genetic science have reshaped the narratives whereby individuals and communities make sense of their personal, family, and communal histories. In this process, unknown connections have been revealed and familiar orthodoxies disrupted. This essay examines the consequences of a particularly unusual revelation - the dawning awareness of the presence of nonhuman and archaic human DNA in human genetic lines - for efforts at writing about identity and society. In this autoethnographic account, I examine my own genetic inheritance of Neanderthal DNA, and posit a performative concept of genetic life writing that begins to unpack the complexities of this …

How To Do The History Of Sexual Science, Benjamin Kahan, Greta Lafleur

Faculty Publications

This introduction maps the ways in which sexual scientific thought circulated during the fin de siècle, tracing the interconnections between and breaks in the global circuits of sexological thought and how this circuitry continues to structure sexuality in the present. In so doing, Kahan and LaFleur position their approach and that of the special issue as a whole within the larger field of sexology, placing it in more robust dialogue with sexuality studies and attending in particular to sexology's racial and imperial logics. They examine the ways in which racial science and colonial knowledge constitute sexual science as an amorphous …

Redox Regulation In Diabetic Kidney Disease, Ilse S. Daehn, Ubong S. Ekperikpe, Krisztian Stadler

Division of Basic Science Faculty Publications

Diabetic kidney disease (DKD) is one of the most devastating complications of diabetes mellitus, where currently there is no cure available. Several important mechanisms contribute to the pathogenesis of this complication, with oxidative stress being one of the key factors. The past decades have seen a large number of publications with various aspects of this topic; however, the specific details of redox regulation in DKD are still unclear. This is partly because redox biology is very complex, coupled with a complex and heterogeneous organ with numerous cell types. Furthermore, often times terms such as “oxidative stress” or reactive oxygen species …

Remote Assessment Of Negative Symptoms Of Schizophrenia, David G. Daniel, Alex S. Cohen, Dawn Velligan, Phillip D. Harvey, Larry Alphs, Michael Davidson, William Potter, Alan Kott, Nina Schooler, Christopher R. Brodie, Raeanne C. Moore, Pierre Lindenmeyer, Stephen R. Marder

Faculty Publications

In contrast to the validated scales for face-to-face assessment of negative symptoms, no widely accepted tools currently exist for remote monitoring of negative symptoms. Remote assessment of negative symptoms can be broadly divided into 3 categories: (1) remote administration of an existing negative-symptom scale by a clinician, in real time, using videoconference technology to communicate with the patient; (2) direct inference of negative symptoms through detection and analysis of the patient's voice, appearance, or activity by way of the patient's smartphone or other device; and (3) ecological momentary assessment, in which the patient self-reports their condition upon receipt of periodic …

Naringenin And Β-Carotene Convert Human White Adipocytes To A Beige Phenotype And Elevate Hormone- Stimulated Lipolysis, Ann A. Coulter, Frank L. Greenway, Dachuan Zhang, Sujoy Ghosh, Cathryn R. Coulter, Sarah L. James, Yanlin He, Luke A. Cusimano, Candida J. Rebello

Division of Basic Science Faculty Publications

Introduction: Naringenin, a peroxisome proliferator-activated receptor (PPAR) activator found in citrus fruits, upregulates markers of thermogenesis and insulin sensitivity in human adipose tissue. Our pharmacokinetics clinical trial demonstrated that naringenin is safe and bioavailable, and our case report showed that naringenin causes weight loss and improves insulin sensitivity. PPARs form heterodimers with retinoic-X-receptors (RXRs) at promoter elements of target genes. Retinoic acid is an RXR ligand metabolized from dietary carotenoids. The carotenoid β-carotene reduces adiposity and insulin resistance in clinical trials. Our goal was to examine if carotenoids strengthen the beneficial effects of naringenin on human adipocyte metabolism. Methods: Human …

Wooing “Willing Dupes”: The Bush Administration’S Use Of Emotional Language In The Drive Toward War With Iraq, Michael F. Russo

Faculty Publications

The publicly available texts of the George W. Bush administration from September 11, 2001, to March 19, 2003, as presented in The Public Papers of the Presidents of the United States, were analyzed for word frequency and the words themselves analyzed for emotional weight using the NRC Emotion Intensity Lexicon. Transcripts of six television news agencies (ABC, CBS, NBC, CNN, FOX, and PBS) were also analyzed for word frequency to determine the extent to which these agencies may have repeated and consequently amplified the rhetoric of the administration. Public opinion polling for this same period was examined in an …

Consumption of contaminated produce remains a leading cause of foodborne illness. Increasingly, growers are altering agricultural practices and farm environments to manage food-safety hazards, but these changes often result in substantial economic, social, and environmental costs. Here, we present a comprehensive evidence synthesis evaluating the efficacy of soil, non-crop vegetation, animal, landscape, and irrigation water management strategies aimed at reducing produce-safety risk in North America. We systematically summarized findings from 78 peer-reviewed papers on the effect of 21 management practices on the prevalence, abundance, or survival of four foodborne pathogens (i.e., E. coli, Salmonella spp., Listeria spp., and Campylobacter spp.), …

Comprehensive Meta-Analysis Of Qtl And Gene Expression Studies Identify Candidate Genes Associated With Aspergillus Flavus Resistance In Maize, Niranjan Baisakh, Eduardo A. Da Silva, Anjan K. Pradhan, Kanniah Rajasekaran

Faculty Publications

Aflatoxin (AF) contamination, caused by Aspergillus flavus, compromises the food safety and marketability of commodities, such as maize, cotton, peanuts, and tree nuts. Multigenic inheritance of AF resistance impedes conventional introgression of resistance traits into high-yielding commercial maize varieties. Several AF resistance-associated quantitative trait loci (QTLs) and markers have been reported from multiple biparental mapping and genome-wide association studies (GWAS) in maize. However, QTLs with large confidence intervals (CI) explaining inconsistent phenotypic variance limit their use in marker-assisted selection. Meta-analysis of published QTLs can identify significant meta-QTLs (MQTLs) with a narrower CI for reliable identification of genes and linked markers …

The Inheritance Of Energy And The Evolution Of Unsustainability, Brian Snyder

Faculty Publications

Across contemporary and historical human groups, there is variation in how cultures interact with the environment and this variation is inherited through culture. Some human-environment relationships maximize group fitness relative to other relationships. Thus, there is heritable, fitness-associated variation in human-environment interactions and so human-environment interactions may be understood to be an evolved trait. However, one fitness-maximizing human-environment relationship could be unsustainable resource extraction. Anthroecological theory proposes that human cultures and genotypes have been selected for unsustainability, although several mechanisms have been proposed for how this selection may have worked. Here, I extend anthroecological theory and argue that energy inheritances …

Quasistatic Evolution With Unstable Forces, Debdeep Bhattacharya, Robert P. Lipton

Faculty Publications

We consider load controlled quasistatic evolution. Well posedness results for the nonlocal continuum model related to peridynamics are established. We show local existence and uniqueness of quasistatic evolution for load paths originating at stable critical points. These points can be associated with local energy minima among the convex set of deformations belonging to the strength domain of the material. The evolution of the displacements, however, is not constrained to lie inside the strength domain of the material. The load-controlled evolution is shown to exhibit energy balance.

Climate And Atlantic Sea-Level Recorded In Southwestern Spain From 6.3 To 5.2 Ma. Inferences On The Messinian Crisis In The Mediterranean, Jean Pierre Suc, Séverine Fauquette, Sophie Warny, Gonzalo Jiménez-Moreno, Damien Do Couto

Faculty Publications

The Mio-Pliocene succession of Andalusia on the Atlantic coast (Guadalquivir Basin) is known as one of the former stratotype candidate for the Andalusian Stage, proposed during the seventies as the last stage of the Miocene. Its type section is located in Carmona, east of Seville. Our investigation includes the drilling of three cored boreholes, which provide bio- and magnetic-stratigraphic data in complement to pre-existing industrial information, and a high-resolution palynological analysis (pollen grains, spores and dinoflagellate cysts). The pollen flora and its climatic quantification provide the mean to correlate the section to the oxygen isotope curve from the Montemayor-1 borehole, …

The Lagrangian Numerical Relativity Code Sphincs_Bssn_V1.0, Stephan Rosswog, Francesco Torsello, Peter Diener

Faculty Publications

We present version 1.0 of our Lagrangian numerical relativity code SPHINCS_BSSN. This code evolves the full set of Einstein equations, but contrary to other numerical relativity codes, it evolves the matter fluid via Lagrangian particles in the framework of a high-accuracy version of smooth particle hydrodynamics (SPH). The major new elements introduced here are: (i) a new method to map the stress–energy tensor (known at the particles) to the spacetime mesh, based on a local regression estimate; (ii) additional measures that ensure the robust evolution of a neutron star through its collapse to a black hole; and (iii) further refinements …

Bates-Fraser, Shadney Que, Eunhan Cho, Guillaume Spielmann, Elif Kadife, John A. Violet, Claudio L. Battaglini, Lee Stoner, David B. Bartlett, Glenn K. Mcconell, Alan Hayes

Faculty Publications

Background: Reduced testosterone levels can influence immune system function, particularly T cells. Exercise during cancer reduces treatment-related side effects and provide a stimulus to mobilize and redistribute immune cells. However, it is unclear how conventional and unconventional T cells (UTC) respond to acute exercise in prostate cancer survivors compared to healthy controls. Methods: Age-matched prostate cancer survivors on androgen deprivation therapy (ADT) and those without ADT (PCa) along with non-cancer controls (CON) completed ∼45 min of intermittent cycling with 3 min at 60% of peak power interspersed by 1.5 min of rest. Fresh, unstimulated immune cell populations and intracellular perforin …

Parental Engagement And Implementation Fidelity In A Mhealth Motor Skills Intervention For Young Children, Amanda E. Staiano, Sanjoy Saha, Robbie A. Beyl, Chelsea L. Kracht, Robert L. Newton, E. Kipling Webster

Population and Public Health Science Faculty Publications

Introduction: Mobile apps (i.e. mHealth) provide unprecedented opportunity for widespread dissemination of health behavior programs. However, for programs directed towards young children, parental engagement may explain differing results of mHealth programs. Within the context of an app-based fundamental motor skill (FMS) intervention that improved children’s motor skills (PLAY), this paper examines parents’ fidelity to the intervention and the extent to which fidelity was related to children’s motor skill improvements. Methods: In the PLAY trial, 72 children aged 3–5 years were randomized for their parents to access a Motor Skills app or Free Play app for a 12-week intervention. The Motor …

Faculty Publications

Oat (Avena sativa L.) is considered a nutritious cereal. Its demand has surged across the globe steadily for half a decade, including in Bangladesh. Because there is no local variety, the current supply in Bangladesh solely relies on imports. This study aimed to introduce grain oats from the United States of America (U.S.A.) to Bangladesh and determine the extent of their adaptability and yield in this new environment. One hundred oat accessions were introduced in collaboration between North South University, Bangladesh and the University of Florida, U.S.A. They were evaluated in field conditions from November 2019 to April 2020 in …

Leaky Gut And The Ingredients That Help Treat It: A Review, Ricardo Santos Aleman, Marvin Moncada, Kayanush J. Aryana

Faculty Publications

The human body is in daily contact with potentially toxic and infectious substances in the gastrointestinal tract (GIT). The GIT has the most significant load of antigens. The GIT can protect the intestinal integrity by allowing the passage of beneficial agents and blocking the path of harmful substances. Under normal conditions, a healthy intestinal barrier prevents toxic elements from entering the blood stream. However, factors such as stress, an unhealthy diet, excessive alcohol, antibiotics, and drug consumption can compromise the composition of the intestinal microbiota and the homeostasis of the intestinal barrier function of the intestine, leading to increased intestinal …

Key Parameters Linking Cyber-Physical Trust Anchors With Embedded Internet Of Things Systems, Michele Maasberg, Leslie G. Butler, Ian Taylor

Faculty Publications

Integration of the Internet of Things (IoT) in the automotive industry has brought benefits as well as security challenges. Significant benefits include enhanced passenger safety and more comprehensive vehicle performance diagnostics. However, current onboard and remote vehicle diagnostics do not include the ability to detect counterfeit parts. A method is needed to verify authentic parts along the automotive supply chain from manufacture through installation and to coordinate part authentication with a secure database. In this study, we develop an architecture for anti-counterfeiting in automotive supply chains. The core of the architecture consists of a cyber-physical trust anchor and authentication mechanisms …

The Rise Of Native Lordships At Pashash, A.D. 200–600, North Highlands Of Ancash, Peru, George F. Lau, Milton Luján Dávila, Jacob L. Bongers, David Chicoine

Faculty Publications

This article examines the rise of native, segmentary lordships in the highlands of north-central Peru. It reports on new excavations and mapping at the seat of a prehispanic polity, Pashash (Recuay culture), a large hilltop center that developed after the collapse of Chavín civilization. Fieldwork revealed monumental constructions and two special activity contexts radiocarbon-dated to ca. a.d. 200–400: an offering area in a large palatial compound and a room-complex with chambers closed off and sealed with feasting refuse. Multiple lines of evidence help reconstruct a regional picture for the establishment of wealthy local elites. Cultural innovations explicitly link new leaders …
