Molecular Detection Of Campylobacter Spp. In Filth Flies Associated With Broiler Breeder Facilities In Oklahoma And Arkansas, Allen Szalanski

Entomology and Plant Pathology Faculty Publications and Presentations

Adult filth flies (Diptera: Muscidae) (non-biting flies that develop in decaying organic matter) are abundant in poultry facilities and may contribute to the dissemination of pathogenic Campylobacter spp. among flocks. We sampled adult house flies, Musca domestica L., and black dump flies, Hydrotaea aenescens (Wiedemann), at five broiler-breeder farms in Oklahoma and Arkansas to determine the prevalence of Campylobacter spp. vectored by filth flies and the effects of farm, fly species, and location (inside vs outside houses) on the rates of Campylobacter spp. occurrence. A total of 1,076 house flies and 1,008 black dump flies were collected inside and outside …

Setting Standards For Engineering Writing. Supplementary Information [Data], Hidden For Review

Higher education research

We present an approach to defining minimum standards of written communication for engineering graduates based on the evaluation of writing samples by industry personnel. Communication skills are widely recognised as core graduate capabilities; however, universities often lack explicit, evidence-based standards aligned with industry expectations. This study applies the borderline group method of empirical standard setting to elicit judgement from industry professionals who supervise graduate engineers. Participants evaluated samples of student writing in two common engineering genres, technical report executive summaries and emails, using dichotomous acceptability judgements supported by evaluations of structure, content and expression. We present a validated framework, supported …

Investigating The Potential For First Year Residential Field Courses To Facilitate The Establishment Of Teacher-Student Relationships In Biological Sciences Undergraduate Degrees, Anne Plessis, Alison Stokes

School of Biological and Marine Sciences

Teacher-student relationships (TSRs) in higher education impact many aspects of the student experience, including engagement and performance. However, relatively little is known about the mechanisms of establishment of TSRs, and in particular how these are influenced by specific learning environments and contexts. Here, we undertake an exploratory investigation using first year biological sciences undergraduate residential field courses to examine how this teaching context affected the frequency and nature of teacher student interactions, and consequently the development of TSRs. Data were collected from teacher and student participants using questionnaires and focus groups. We found that interactions during fieldwork took place frequently …

Beyond Digital Pessimism: How A Focus On Trust Can Enhance Eu Digital Law, Neil Richards, Woodrow Hartzog, Claire Boine, Lea Despotis

Faculty Scholarship

Lawmakers looking to foster technological innovation on the European market are adopting laws they hope will promote consumer trust in digital products. Their strategy can be broken down into three components. First, they aim to empower consumers to choose how much data they want to share with companies through an express consent framework. Second, they seek to avoid harms from digital products through product safety law such as adapting the Product Safety Regulation to digital products or adopting the AI Act. Third, they endeavor to prevent manipulation of consumers through digital means.

In this essay, we argue that while laudable, …

Measuring Lawyer Mental Illness: Evidence From Two National Surveys, Benjamin David Pyle, Clifford Rosky

Faculty Scholarship

The American Bar Association declared a “well-being crisis” among lawyers, but the empirical basis for this claim has been contested in recent years. This study systematically compares two high-quality, nationally representative surveys —the National Health Interview Survey (NHIS) and the National Survey on Drug Use and Health (NSDUH)—to measure the prevalence of mental illness and alcohol misuse among lawyers. In both surveys, lawyers report elevated rates of alcohol misuse compared to the general public and similarly educated peers. The NHIS finds that lawyers experience psychological distress at rates lower than the general public and similar to, or moderately higher than, …

Taking Scale Seriously In Technology Law, Mark P. Mckenna, Woodrow Hartzog

Faculty Scholarship

Issues of scale—the relationship between the amount of an activity and its associated costs and benefits—permeate discussions around law and technologies. Indeed, it’s not much of an exaggeration to say that scale is the reason for most technology regulation.

But it’s not always clear how lawmakers and judges conceptualize “scale” when approaching questions around automated technologies. Scale is often used intuitively, just to mean “more.” But scale is not always just about more—scale can introduce new harms and benefits along different dimensions, not simply costs or efficiencies of greater magnitude.

In this Article, we argue for a more sustained interrogation …

Spending Programs And The New Roberts Court, Nicole Huberfeld

Faculty Scholarship

The Supreme Court is poised to place new limits on Congress’s spending power at the urging of states vying for regulatory dominance, particularly in health care and public health. This article is the first to highlight and catalog the throughlines of argumentation, which sparked after states successfully challenged the ACA but have grown into opposing more than Medicaid’s cooperative federalism. This means federal and state programs that heavily rely on federal spending power are at risk, so studying this pattern is imperative. The article begins with a descriptive account of increasing spending power challenges, which make use of converging factors …

Against Ai Half Measures, Woodrow Hartzog, Neil Richards, Ryan Durrie, Jordan Francis

Faculty Scholarship

So far, U.S. consumer protection policy for artificial intelligence (AI) accountability has largely consisted of industry-led approaches such as encouraging transparency, mitigating bias, promoting principles of ethics, and empowering people. These approaches are vital, but they are only half measures. To bring AI within the rule of law, lawmakers must start drawing substantive lines.

In this Article, we identify four AI regulatory approaches to consumer, data, and democratic harms as half measures. First, transparency does not produce accountability on its own. Second, while mitigating bias in AI systems is critical, even unbiased systems are a threat to the vulnerable. Third, …

Uncorrected, Janet Freilich, W. Nicholson Price Ii

Faculty Scholarship

In addition to making rules and deciding outcomes, the legal system generates, curates and shares information. When the system gets rules and outcomes wrong, it is obviously a problem, and much effort (and scholarly attention) goes into identifying those mistakes and fixing them. But the system also gets information wrong; a problem mostly overlooked by policymakers and scholars. Those information mistakes matter too: they are prevalent and harmful. We show here that even when the mistakes are widely known and the errors broadly acknowledged, the information very often goes uncorrected. As a result, people make decisions based on bad information …

Five Lessons From Ken Kersch’S Conservatives And The Constitution For The Present Moment, James E. Fleming, Linda C. Mcclain

Faculty Scholarship

Timothy Snyder’s On Tyranny, a New York Times bestseller, has the subtitle, “Twenty Lessons from the Twentieth Century.” Ken Kersch’s Conservatives and the Constitution: Imagining Constitutional Restoration in the Heyday of American Liberalism (2019) provides at least twenty lessons from the second half of the Twentieth Century about the development of conservative constitutional thought and activism. Although conservatism has changed in many ways since the 1954-1980 period on which Kersch’s book focuses, these lessons are relevant for understanding the present political moment, filled with concerns that the U.S., during the second Trump Administration, is lurching toward tyranny, authoritarianism, and …

Corporate Childrearing, Katharine B. Silbaugh

Faculty Scholarship

With children influencing a trillion dollars in spending annually, corporations actively seek to shape children's identities in support of consumer culture and profit. Yet there are no scholarly treatments or theories of the legal relationship between children and corporations. Instead, scholars address individual industries such as food, social media, cosmetics, tobacco, or fashion, missing the structural role corporations play in children's identity formation. Family law evaluates child wellbeing interventions using a triangle to map the legal dynamics among child, parent, and state. This article adds corporations as fourth actors, reconceptualizing that triangle as a square. This square provides the first …

The Power And Peril Of The Aca's Universality At Fifteen, Nicole Huberfeld

Faculty Scholarship

As part of the symposium "15th Anniversary of the ACA: A Health Equity Review," this essay explores the ACA's mix of private law and public law provisions that rendered measurable improvements in health equity and health outcomes, especially for populations that experienced longstanding health disparities before its enactment.  Congress’s central objective was near-universal health insurance coverage, and the ACA employed a variety of mechanisms to reach that goal. The law’s health equity successes grew from establishing a principle of inclusion across federal statutes. This principle, which I have called “universality,” centered a human right to health approach: No longer would …

The Missing Constitutional Law Of Executive Conditions, Nicole Huberfeld, Matthew B. Lawrence

Faculty Scholarship

This Article contributes to development of the constitutional law of executive conditions. Courts are wrestling with the constitutionality of federal efforts to encourage what the federal government cannot mandate—speech on particular subjects, participation in cooperative federalism programs, and so on—but have failed to appreciate an important distinction. Binding statutory conditions articulated by Congress or an executive branch delegee (statutory conditions) and non-binding executive conditions articulated by executive branch actors engaged in regulation by deal (executive conditions) are different in constitutionally salient ways that can and should inform the development of workable doctrine. Yet courts, advocates, and scholars have only begun …

Social Science Contributions To The Global Action Plan On Antimicrobial Resistance Management, Mathieu Poirier, Jaskeerat Singh, Isaac Weldon, Clare I. R. Chandler, Daniela Corno, Laura Valtere, Pedro Henrique D Batista, Daniel Carelli, Geneviève Boily-Larouche, Sonia Lewycka, Fiona Emdin, Kathleen Liddell, Timo Minssen, Ilaria Natali, Susan Nayiga, Iruka N. Okeke, Emmanuel Olamijuwon, Kevin Outterson, Julianne Piper, Kayla Strong, Jarnail Singh Thakur, Kednapa Thavorn, Maarten Van Der Heijden, A. M. Viens, Mary Wiktorowicz, Steven J. Hoffman

Faculty Scholarship

Social science research on antimicrobial resistance has gained traction in the last decade, employing a diverse set of theoretical perspectives to better understand topics ranging from antimicrobial stewardship to political coordination.4 As the action plan commitments will be updated in 2026, an opportunity exists to employ a broader social science scope to accelerate national antimicrobial resistance interventions.

In January 2025, the Global strategy lab convened leading antimicrobial resistance social scientists from a variety of disciplines to determine which new ways of understanding antimicrobial resistance could catalyse and incentivize action. Three conceptions stood out as important to revisions of the action …

The Punishment Paradox, Steven Arrigg Koh

Faculty Scholarship

What does criminal punishment do? Across centuries of criminal legal thought, a shared answer persists: punishment incapacitates the wrongdoer. And yet punishment sometimes yields its opposite. Paradoxically, punishment sometimes becomes a rallying point-expanding community identification and solidarity around the defendant. This Article shows this punishment paradox using the 2023-24 prosecutions of President Trump and recent and historical case examples-from Luigi Mangione to Karen Read to Rosa Parks. By arguing that criminal law can generate solidarity rather than stigma, the Article both rethinks foundational theories of punishment and reconsiders the role of criminal law in democratic politics. Such an approach transcends …

Memory Warriors, Pluralists, And Abnegators In Constitutional Interpretation: An Essay On Jack Balkin's Pluralist Originalism In Memory And Authority, Jed Handelsman Shugerman, Zachary Shugerman Handelsman

Faculty Scholarship

Jack Balkin’s Memory and Authority: The Uses of History in Constitutional Interpretation brings into conversation the scholarly insights of constitutional theory, history, and the growing field of “the politics of memory,” especially the concept of the “memory entrepreneur.”

Balkin appropriately connects the memory wars in American constitutional law back to Eastern

European memory wars during the World Wars and their aftermath. Prompted by Balkin, we turn to Jan Kubik and Michael Bernhard edited volume Twenty Years After Communism (2014), which has become even more widely influential after Putin’s invasion of Ukraine and a new round of Eastern European memory wars. …

Third-Party Funding: Balancing Transparency, National Security, And Access To Justice, Victoria Sahani

Faculty Scholarship

Many lawmakers who have recently become aware of the multi-billion-dollar global third-party funding industry are raising new national security concerns that further complicate preexisting, longstanding debates about transparency, disclosure, access to justice, and the best way to regulate third-party funding. In response, this Article briefly asserts three main points relating to the question of how best to regulate third-party funding. First, this Article explains the third-party funding industry, including its global regulatory landscape and how it serves three distinct populations: consumers, businesses, and law firms. Second, this Article explains that third-party funding is one tool that can help expand access …

The Hypocrisy Of Data Governance, Zubair Shafiq, Olivia Figueira, Athina Markopoulou, Woodrow Hartzog, Michael Lavine

Faculty Scholarship

“Data governance” is an empty term, like a Rorschach inkblot just waiting to be filled with meaning. Tech companies take advantage of this ambiguity to craft narratives about their data-governance capabilities to fit their audience and purpose. On one hand, tech companies brag about their data-governance capabilities when it fits their business model (for example, to advertisers) and public image (for example, to their customers). On the other hand, tech companies claim that meaningful data governance is challenging or impossible when accountability is demanded.

In this Article, we argue that tech companies systematically misrepresent or selectively ignore their data-governance capabilities. …

Romanist-Bourgeois Property And The Development Of The Modern Capitalist World System, Anna Di Robilant

Faculty Scholarship

This article examines the role of Romanist-bourgeois property law in the development of the modern capitalist world system, focusing on how nineteenth-century jurists deliberately crafted and adapted Roman law-based property doctrines to address the evolving social relations of production in both Europe and its peripheries. Rather than viewing legal concepts as merely reflective of broader economic transformations, the author highlights the active role played by a professional class of jurists in shaping property law to legitimize and structure emergent capitalist class dynamics. The article critically engages with competing scholarly perspectives that either privilege market expansion or downplay class relations, arguing …

Privacy’S Autonomy Thicket: Disentangling Choice, Consent And Control, Jordan Francis, Woodrow Hartzog, Neil Richards

Faculty Scholarship

When it comes to talking about autonomy, privacy law could use a little clarity. Its discourse uses terms like “choice,” “consent,” and “control” to evoke autonomy, but these terms are too rarely defined and too often used interchangeably, even though they can mean very different things. The three terms have become entangled in a way that has become confusing and counterproductive. We call this problem “privacy’s autonomy thicket,” and it matters because it encourages talking past each other in policy debates, enabling the redefinition of these terms in misleading ways that produce weak and disempowering “notice and choice” regimes.

The Anti-Federalism Of Hr1, Nicole Huberfeld

Faculty Scholarship

The budget reconciliation bill signed on July 4, 2025 (“HR1”) weakened the Patient Protection and Affordable Care Act (ACA) and its core goal of near-universal health insurance coverage. To maintain 2017 tax cuts, Congress curtailed the ACA’s Medicaid eligibility expansion; simultaneously, HR1 limited the kinds of options states have been able to exercise within Medicaid while pushing the costs of deep cuts down to states. This essay argues that HR1 embodies an anti-federalism approach, and that anti-federalism is not the same as federalizing health reforms. In the past, Congress sometimes federalized health care or public health reforms to respond to …

Regulating Crisis Pregnancy Centers After Nifla And Dobbs: Controversies Over When Government Is Imposing An Orthodoxy About Abortion, Linda C. Mcclain

Faculty Scholarship

How does this broader sense of Barnette’s proscription of government from imposing “what shall be orthodox” implicate governmental restrictions on reproductive autonomy? Battles over reproductive freedom centrally implicate objections that government is unconstitutionally imposing a gender orthodoxy. Arguments for a right of personal autonomy embodying an antitotalitarian principle of liberty are arguments for a right to resist governmental imposition of an orthodoxy— for example, an idea about the natural or traditional role of women as mothers together with a view about how best to respect the sanctity of life. Rights to reproductive autonomy, grounded in personal autonomy and equality, …

Exploring Excessive Absences In An Urban School Setting: Implications For Student Academic Success And High School Graduation, Tamieka Mclaughlin

Theses and Dissertations

This qualitative phenomenological study explored the perspectives of parents and teachers regarding excessive student absenteeism in an urban high school setting and the implications of persistent absences for students' academic success and high school graduation. Excessive absenteeism remains a major challenge for schools in urban communities where children experience multiple personal, family, school and community factors that may influence attendance. Understanding how parents and teachers perceive these factors can provide insight into the experiences and challenges associated with chronic absenteeism, as well as the strategies they believe may support improved student attendance, academic success, and progress towards high school graduation. …

Theses and Dissertations

This applied dissertation was designed to investigate the preparedness of kindergarten children in early reading skills, drawing comparisons from their experiences in comparable preschool programs and to gain insight about how to address the problem of low early reading skills among children entering kindergarten. Using archival data from i-Ready reading diagnostic tests over a 4-year period (2021-2022 to 2024-2025), the researcher compared students who attended an urban K-8 Center Head Start program (n=47) with students from other preschools (n=33).

The researcher conducted an independent t-test with SPSS, version 30 software, to analyze differences at the baseline (Assessment Period 1) and …

Improving Human Dimensions Of Conservation Planning: Challenges And Opportunities For Sustainable Conservation Outcomes, Vivian Hulugh

Electronic Theses and Dissertations

Conservation planning is important to ensure both ecological and social benefits of natural resources, including the maintenance of functional ecosystems and stable wildlife populations as well as the provision of resources that communities rely on. Yet, the integration of the human dimensions of conservation planning remains limited in practice. This thesis examines conservation planning in South Dakota and within Joint Venture (JV) partnerships, using qualitative methods to identify challenges and opportunities for more effective and coordinated planning. In chapter one, I examine how collaboration, public participation, and the use of climate information are integrated conservation planning in South Dakota and …

Investigation Of Perennial Clover Living Mulch And Reduced Tillage Effects On Weed Suppression, Crop Metrics, And Yield Of Organic Cabbage And Sweet Corn In The Northern Great Plains, Kristina Harms

Electronic Theses and Dissertations

Vegetable farmers often face weed management and soil health challenges, such as nitrate leaching, soil compaction, and top-soil loss. Sustainable agriculture is a forefront of innovation compared to conventional agriculture. Living mulches, non-cash crops grown alongside cash crops, have demonstrated weed suppression and impact on the promotion of sustainable agriculture. Yet studies have not evaluated established living mulch systems on cash crop quality and yield. This study conducted in 2023, 2024, and 2025 at SDSU Southeast Research Farm, Beresford, SD, USA evaluates the impact of established ‘Dynamite’ red clover (Trifolium pratense), ‘Domino’ white clover (T. repens), and ‘Aberlasting’ white × …

Production, Characterization, And Diagnostic Application Of Monoclonal Antibodies Against The N-Protein Of Avian Metapneumovirus Subgroup B, Ravi Gupta

Electronic Theses and Dissertations

Avian metapneumovirus (aMPV) is a respiratory pathogen that causes Turkey Rhinotracheitis (TRT) in turkeys and Swollen Head Syndrome (SHS) in chickens. The infection leads to facial swelling, nasal discharge, reduced egg production, and poor growth. This virus is classified into four subgroups: aMPV-A, B, C, and D, with two other novel subgroups, in which aMPV-A, B, and C are most prevalent in the commercial flocks. In early 2024, aMPV-A and B outbreaks have been reported in the US, resulting in severe economic losses. An economic assessment estimates around $112 million in losses in Minnesota and up to $434 million in …

Towards Energy Access For All: Developing The Lived Energy Experience Index (Leei), Kentina Annie Ishimwe

Electronic Theses and Dissertations

Energy is the fuel that powers the engine of civilization. Energy access metrics ensure that nations continuously work towards providing access for all. However, the prevalent binary indicator fails to consider that energy needs to be usable, accessible, affordable, and reliable. As a result, numerous tiered and multidimensional metrics, such as the Multi-Tier Framework, came about to bridge the gap but proved to be complex and complicated to implement. This study presents the existing literature review, assesses the limitations of current energy access measurement frameworks, and compares household energy needs with reported access statistics. Based on the findings, the Lived …

Finite Mixture Modeling Towards Applications In Material Science And Biomedical Data, Jason Hasse

Electronic Theses and Dissertations

This dissertation contains three chapters on different applications of mixture regression models, broadly in materials science and public health. We begin with a basic application of finite mixture models and regression mixture models. The materials science analysis was performed entirely using data from finite element simulations of the additive manufacturing process via powder bed fusion. Visualization of the clustering solution as applied to the additive manufacturing designs highlighted the intuitive patterns that could be found. These patterns simultaneously yield the regression coefficients and subgroups of the geometric regions, providing a way to predict stresses and strains in a new geometry …
