Quieting The Cacophony: How To Reduce Greenwashing And Environmental Damage From The Food Industry, Alex Woodward

Kentucky Journal of Equine, Agriculture, & Natural Resources Law

In this article, Alex G. Woodward addresses the problem of greenwashing and environmental harm caused by industrial agriculture and misleading food labeling. Woodward explains that while agriculture is essential to feeding a growing global population, its large-scale, profit-driven practices cause significant environmental damage. Woodward argues for a strategy that compels transparency through warning labels and expanding credible certification frameworks. Woodward proposes that the USDA implement a tiered labeling system under its Organic Program and require factual, noncontroversial disclosures about environmental harms on food packaging, with the goal of informing consumers, restoring trust, and incentivizing environmentally responsible agricultural practices.

This Land Is Our Land: Addressing Foreign Ownership Of Agricultural Land In The United States, Will Miller

Kentucky Journal of Equine, Agriculture, & Natural Resources Law

In this note, Will Miller examines the rapid increase in foreign ownership of U.S. agricultural land and the national security and food security risks it creates. He explains that the Agricultural Foreign Investment Disclosure Act (AFIDA) only requires reporting of foreign ownership but imposes no restrictions, leaving regulation largely to a patchwork of state laws. Miller argues for federal oversight, contending that matters of foreign affairs and national security are best handled at the national level. He proposes a comprehensive federal regulatory scheme which would set nationwide minimum standards such as prohibiting ownership by foreign adversaries and capping total foreign-held …

The Impact Of Veterinary Stewardship Program Implementations On Backyard Chicken Farming In Rural Georgia, Lauren Ashley Herrin

Kentucky Journal of Equine, Agriculture, & Natural Resources Law

In this article, Lauren Ashley Herrin examines the impacts of new FDA veterinary stewardship regulations on backyard chicken farming in rural Georgia. She explains that requiring prescriptions for previously over-the-counter antibiotics disproportionately harms low-income and rural communities by limiting access to affordable veterinary care, worsening risks of disease spread and public health threats. Herrin argues for policy approaches that balance antimicrobial resistance concerns with the realities of rural accessibility. She proposes solutions such as telehealth veterinary consultations, scholarship programs to encourage rural veterinary practice, and expanding prescriptive authority for veterinary technicians to ensure sustainable animal health care in underserved areas

Kentucky Journal of Equine, Agriculture, & Natural Resources Law

In this note, Abbey Norvell analyzes the dangers of radon exposure in Kentucky schools, highlighting the state’s nation-leading lung cancer rates and the heightened risks for children. She explains that Kentucky has no law requiring schools to test for or mitigate radon levels, leaving students vulnerable. Norvell argues for mandatory radon testing and remediation in Kentucky schools. She proposes legislation modeled on other states requiring testing in both public and private schools within five years, and remediation within two years if levels exceed EPA standards.

Pesticide Lies! A Call For Epa Action As Recent Judicial Decisions Reveal The Harmful Truth Resulting From Exposure, Stevi Whitman

Kentucky Journal of Equine, Agriculture, & Natural Resources Law

In this note, Stevi Whitman analyzes the dangers of weak pesticide regulation in the United States. Whitman explains that the EPA’s reliance on the vague “unreasonable adverse effects” standard under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) allows harmful products like Roundup to remain on the market despite strong evidence of health risks. Whitman argues for strengthening U.S. pesticide laws to match the European Union’s stricter safety threshold. She proposes amending FIFRA to require proactive bans on hazardous pesticides and greater accountability from manufacturers to better protect public health and the environment.

Analysing The Us—China “Ai Cold War” Narrative, Yujia He, Richard Heeks

Patterson School of Diplomacy and International Commerce Faculty Publications

Discussions about artificial intelligence (AI) are gaining prominence in the recent revival of “cold war” narratives comparing US-China relations today to the historical rivalry between the US and the Soviet Union. Drawing on a review of existing academic and policy literature engaging with the “AI cold war” narrative, this paper examines how the narrative is justified, and numerous ways that it can be challenged. It finds that the framing is largely driven by the securitisation of AI, as state actors and policy pundits view AI innovations’ dual-use capabilities as key to national security and ideological competition. However, critics posit that …

Simpson's Tachytely Or Bradytely? The Importance Of Quantifying Rate Uncertainty, Rosana Zenil-Ferguson, Lee Hsiang Liow

Biology Faculty Publications

The spectacular variation in species forms and richness across space and time can be explored using sophisticated and powerful tools recently developed by evolutionary modellers. In this contribution, we ask if the classic ‘Simpsonian’ view of tachytelic (fast), horotelic (standard) and bradytelic (slow) diversification rates can be distinguished with currently available tools and data. A neglected topic here is the role that the uncertainty of diversification rate estimates plays, where the lack of in-depth uncertainty measures could hinder our ability to confidently suggest differences in speciation or extinction rates in any given comparison. We propose quantifying the relative uncertainty of …

“I Just Don’T Find It Interesting”, Jennifer L. Osterhage, Utku Caybas, Jaeyun Han, Ellen L. Usher

Biology Faculty Publications

Situated expectancy-value theory (SEVT) posits that students’ expectancies for success, task values, and perceived costs affect their performance in STEM courses. Less is known about how students’ majors and timing of course completion affect motivational processes. Using the SEVT framework, this study utilised a convergent mixed methods approach to investigate academic motivation among students (N = 646) who enrolled in introductory biology at a large public university. Survey data revealed that students majoring in Biology were more motivated than students from other majors, although academic major was not directly associated with final grade. Upper-level students reported significantly lower competence-related beliefs …

Seasonal Divergence In Reproductive Timing On The Verge Of Spring, Devraj Singh, Adam M. Fudickar, Ellen D. Ketterson

Biology Faculty Publications

Every year as spring approaches and day length increases, many birds begin to reproduce, an annual expression of seasonal phenology that requires physiological preparation. In species distributed over a broad geographic range, populations that breed at higher latitudes are often migratory and delay reproduction until later in the year as compared to those breeding at lower latitudes. Dark-eyed Juncos serve as an excellent model for understanding the timing mechanisms regulating population-level variation in seasonal reproductive responses. We compared two seasonally sympatric dark-eyed junco populations in early spring. One migrates (Junco hyemalis hyemalis) and breeds in Alaska and Canada, while the …
