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.), …

Faculty Publications

Lycopene, the pigment principally responsible for the red colour of tomatoes, is well-known for its strong antioxidant property and substantial health benefits. In this study, the optimal combination of factors for lycopene extraction from tomato pomace was identified using response surface methodology. The best practically feasible results maximising both lycopene yield and antioxidant activity of the extract were obtained by applying a ratio of ethyl acetate to tomato waste of 35:1 (v/w), at a temperature of 55°C for 100 min of extraction. The extract was then added to the peanut oil to evaluate its oxidative stability during 60 days of …

Going With The Flow: The Supply And Demand Of Sediment Retention Ecosystem Services For The Reservoirs In Puerto Rico, R. De Jesus Crespo, M. Valladares-Castellanos, Volodymyr V. Mihunov, T. H. Douthat

Faculty Publications

Impounding surface waters in reservoirs is a major mechanism for providing water for human consumption, including potable water, hydroelectric power, and industrial uses. Building reservoirs incurs environmental and social costs, and therefore safeguarding their effectiveness and longevity is a concern of clear public interest. One factor that affects the longevity of reservoirs is sedimentation, a process exacerbated by land use conversion in upstream watershed areas. Despite the economic importance of preventing sedimentation in existing reservoirs, few consumers are aware of the natural features that provide sediment retention services and the relevance of their conservation in their daily lives. Moreover, managing …

The authors identify 126 factors guiding the characteristics, adoption, governance, and business impact of the cloud. Further, they employ a rigorous analysis that situates our review at the intersection of …

An Upper Bound For The Circumference Of A 3-Connected Binary Matroid, Manoel Lemos, James Oxley

Faculty Publications

Jim Geelen and Peter Nelson proved that, for a loopless connected binary ma-troid M with an odd circuit, if a largest odd circuit of M has k elements, then a largest circuit of M has at most 2k − 2 elements. The goal of this note is to show that, when M is 3-connected, either M has a spanning circuit, or a largest circuit of M has at most 2k − 4 elements. Moreover, the latter holds when M is regular of rank at least four.

Effect Of Estradiol And Predator Cues On Behavior And Brain Responses Of Captive Female House Sparrows (Passer Domesticus), Melanie G. Kimball, Courtney T. Harding, Kaitlin E. Couvillion, Keegan R. Stansberry, Tosha R. Kelly, Christine R. Lattin

Faculty Publications

The presence of predators can cause major changes in animal behavior, but how this interacts with hormonal state and brain activity is poorly understood. We gave female house sparrows (Passer domesticus) in post-molt condition an estradiol (n = 17) or empty implant (n = 16) for 1 week. Four weeks after implant removal, a time when female sparrows show large differences in neuronal activity to conspecific vs. heterospecific song, we exposed birds to either 30 min of conspecific song or predator calls, and video recorded their behavior. Females were then euthanized, and we examined neuronal activity using the expression of …

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 …

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 …

What Comes Next?, Neil Fulton

Faculty Publications

The United States stands at an important crossroads. Polarization and paralysis are the political norm. Social divisions are deep and seemingly intractable. Concerted action is disappointingly rare. Social and political pressures continue to build like tectonic plates waiting to release. What will come next? This Article begins with a description of the current situation before turning to a consideration of five possible paths forward. First, stasis. There may be more of the same with limited systemic shocks releasing small amounts of pressure without a fundamental change of circumstances. Second, rupture. Building pressure may tear the current political and social system …

South Dakota Legisprudence: A Catalog And Analysis, Neil Fulton

Faculty Publications

Statutes provide much of the modern legal body of law. It is necessary for any lawyer to have a good understanding of "legisprudence," the rules for enactment and interpretation of statutes. South Dakota has developed a useful body of legisprudence through both statutes and cases that provide direction about how statutes should be read. This article provides a descriptive collection and normative assessment of these interpretive rules.

The Supreme Court Corrects A Seventy-Five Year Distortion In Establishment Clause Jurisprudence, Patrick Garry

Faculty Publications

In Kennedy v. Bremerton School District, the US. Supreme Court ruled that the Establishment Clause did not prohibit a high school football coach from offering a brief midfield prayer at the conclusion of games. The Ninth Circuit had held that the coach's free exercise rights had to yield to the Establishment Clause's prohibition of conduct that might reflect a state endorsement of religion. In overturning the Ninth Circuit, the Supreme Court issued an historic and far-reaching ruling on the scope and nature of the Establishment Clause, providing the first truly clarifying decision in this area in the past seventy-five years. …

Sodium Propionate Or Sodium Butyrate Promotes Fatty Acid Oxidation In Hepg2 Cells Under Oxidative Stress, Kristina J. Cook, Ann Coulter, Michael Keenan, Frank Greenway, Jack N. Losso

Faculty Publications

The beneficial effects of sodium butyrate (NaB) and sodium propionate (NaP) on fatty acid oxidation (FAO) genes and production of proinflammatory cytokines related to nonalcoholic fatty liver disease (NAFLD) were evaluated using HepG2 human liver hepatocellular carcinoma cells exposed to palmitate/oleate or lipopolysaccharides (LPSs) as a model. The results showed that NaP or NaB was able to promote FAO, regulate lipolysis, and reduce reactive oxygen species production by significantly increasing the mRNA expression of peroxisome proliferator-activated receptor gamma coactivator 1 alpha (PGC-1α), peroxisome proliferator-activated receptor alpha (PPARα), adipose triglyceride lipase (ATGL), carnitine palmitoyltransferase 1 alpha (CPT1α), fibroblast growth factor 21 …

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 …

Disparities In Spatial Accessibility Of Primary Care In Louisiana: From Physical To Virtual Accessibility, Fahui Wang, Yutian Zeng, Lingbo Liu, Tracy Onega

Faculty Publications

Telehealth has been widely employed and has transformed how healthcare is delivered in the United States as a result of COVID-19 pandemic. While telehealth is utilized and encouraged to reduce the cost and travel burden for access to healthcare, there are debates on whether telehealth can promote equity in healthcare services by narrowing the gap among diverse groups. Using the Two-Step Floating Catchment Area (2SFCA) and Two-Step Virtual Catchment Area (2SVCA) methods, this study compares the disparities of physical and virtual access to primary care physicians (PCPs) in Louisiana. Both physical and virtual access to PCPs exhibit similar spatial patterns …

Reconsidering The Good Of Improving Accountability, Roy L. Heidelberg

Faculty Publications

Among the rhetorical pleas that follow most instances of public dissatisfaction is the call for more or better accountability. Accountability is a lauded notion, a “golden concept” that is considered widely as critical to the success of democratic government. Such pleas, I will argue, are misplaced. Rather than starting from the premise of accountability as an idea that no one can be against, I consider the possibility that accountability undermines the very notion it ostensibly promotes: self-government. The concept of accountability in modern political theory is tied more closely to the emergence of an impersonal administrative state than it is …

Between Black Mothers And Daughters: A Critical Intergenerational Duoethnography On The Silence Of Health Disparities And Hope Of Loud Healing, Asha S. Winfield, Hope Hickerson, Deshara C. Doub, Ann R. Winfield, Brigitte Mcphatter

Faculty Publications

Introduction: Black American women's health outcomes have been altered by a number of factors. Those factors include social determinants of health, lack of culturally competent healthcare providers, and generations of medical racism leading to prolonged pain, delayed care, and sometimes, untimely deaths. Methods: This original research article centers Southern Black women's lived experiences through family storytelling.

Building from theorizing on loud healing, two Black daughters turned the mic on for their mothers by engaging in a critical intergenerational double duoethnography to …

Prep On Tiktok: Benefits, Barriers, And Possibilities, Joseph Schwartz, Josh Grimm, Cameron Jamison

Faculty Publications

HIV remains a serious problem in the U.S. particularly for men who have sex with men. PrEP is an intervention that can dramatically decrease the risk of HIV infection. Because rates of PrEP adoption have been lower than anticipated, researchers have called for new tactics for promoting PrEP. For this reason, we analyzed PrEP messaging on TikTok. In an analysis guided by the Health Belief Model, we found that discussions of PrEP benefits and barriers were most common on TikTok. Severity and susceptibility were least common. We distilled these findings into suggestions for promoting PrEP adoption.

In Search Of Founding Era Registers: Automatic Modeling Of Registers From The Corpus Of Founding Era American English, Liina Repo, Brett James Hashimoto, Veronika Laippala

Faculty Publications

Registers are situationally defined text varieties, such as letters, essays, or news articles, that are considered to be one of the most important predictors of linguistic variation. Often historical databases of language lack register information, which could greatly enhance their usability (e.g. Early English Books Online). This article examines register variation in Late Modern English and automatic register identification in historical corpora. We model register variation in the corpus of Founding Era American English (COFEA) and develop machine-learning methods for automatic register identification in COFEA. We also extract and analyze the most significant grammatical characteristics estimated by the classifier for …

Data Visualization In 10-K Filings, Theodore E. Christensen, Karson E. Fronk, Joshua A. Lee, Karen K. Nelson

Faculty Publications

The Securities and Exchange Commission encourages the presentation of information or data in graphical form to improve users’ ability to understand financial disclosures. We find a dramatic increase in the disclosure of both qualitative and quantitative infographics in 10-K filings over time and substantial cross-sectional variation in firms’ choices regarding image types, data content, and the placement of infographics within 10-Ks. We provide evidence on factors associated with firms’ use of infographics and explore the persistence with which they are disclosed over time. Finally, we investigate the relation between the use of infographics and uncertainty in capital markets.

The Right To A Public Trial, Conditional Courtroom Entry And Tiers Of Constitutional Scrutiny, Stephen Smith

Faculty Publications

The constitutional test the SupremeCourt has prescribed to review courtroom closures for compliance with the Sixth Amendment’s right to a public trial is in the nature ofstrictscrutiny. The Courtrequires an “overriding interest” to justify the closure, and a narrow, minimally restrictive scope to the closure. Many lower courts have imposed a less demanding test for “partial” closures, which admit to the courtroom some, but not all, of the public. These courts require a less demanding justification before closing the courtroom to certain individuals—the justification need be only “substantial,” ratherthan “overriding.” Thisstandard is in the nature of intermediate scrutiny, as applied …

Creating Continents: Archean Cratons Tell The Story, Carol D. Frost, Paul A. Mueller, David W. Mogk, B. Ronald Frost, Darrell J. Henry

Faculty Publications

The record of the first two billion years of Earth’s history (the Archean) is notoriously incomplete, yet crust of this age is present on every continent. Here we examine the Archean record of the Wyoming craton in the northern Rocky Mountains, USA, which is both well-exposed and readily accessible. We identify three stages of Archean continental crust formation that are also recorded in other cratons. The youngest stage is characterized by a variety of Neoarchean rock assemblages that are indistinguishable from those produced by modern plate-tectonic processes. The middle stage is typified by the trondhjemite-tonalite-granodiorite (TTG) association, which involved partial …
