Kentucky Transportation Center Research Report

Highway construction workers operate in high-stress, hazardous settings where they have to perform physically taxing labor in environments where exposure to variable weather conditions, heavy equipment, high volumes of vehicle traffic, and other conditions that induce stress and anxiety are the norm. Up to 70% of workers in this industry have reported experiencing mental health issues, including secondary traumatic stress, post-traumatic stress disorder, depression, anxiety, and substance abuse disorders. Few state departments of transportation, however, offer adequate resources staff can draw on to effectively manage their psychological well-being. To help Kentucky Transportation Cabinet (KYTC) roadway maintenance and construction workers develop …

Criminal Organizations And Nuclear Threats In Southeast Asia, Gary Ackerman, Thomas Guarrieri, Justin V. Hastings, Steven Hoodjer

International Journal of Nuclear Security

Increasing global interest in nuclear energy and peaceful uses of nuclear technology has led to facilities in emerging countries with nuclear materials and radioactive sources that could be stolen, sabotaged, or otherwise accessed by criminals. In this paper, we created a framework to assess the motivations and capabilities of criminal networks and measure the threats they may pose to different stages of the nuclear fuel cycle in emerging nuclear states. We applied the framework to a unique dataset, capturing characteristics of criminal organizations active in Southeast Asia, which allowed us to assess which criminal organizations are most likely to pose …

Mitigation Of Pm Eddy Current Losses Using Offset Windings In Coreless Afpm Machines, Matin Vatani, Diego A. Lopez Guerrero, John F. Eastham, Dan M. Ionel

Electrical and Computer Engineering Graduate Research

Permanent magnet eddy current losses can become substantial in coreless stator axial flux permanent magnet (AFPM) machines operating at high speeds and under high electric loading, potentially leading to elevated temperatures and an increased risk of demagnetization. This paper investigates the origins of these losses through a detailed harmonic analysis of the winding factor and introduces a mitigation strategy. The proposed method utilizes two-layer offset windings, effectively minimizing undesirable armature flux harmonics through harmonic interaction between the offset layers. Two cases are studied: one in which each stator layer is connected to a separate inverter and another in which both …

Multiplicity As An Ai Governance Principle, Michal Shur-Ofry

Indiana Law Journal

As AI becomes increasingly embedded in our daily lives, this Article explores one of its critical, yet overlooked, societal implications: the propensity of large language models (LLMs) to generate mainstream, standardized content, potentially narrowing their users’ worldviews.

Taking a close look at the technological underpinnings of LLMs, the analysis suggests that—due to the combination of human judgments, training datasets, and inherent features of the underlying technological paradigm—LLMs’ outputs are likely to be geared toward the popular and to project to their users concentrated, mainstream worldviews, sidelining a broader spectrum of perspectives. This Article explores the asymmetrical power relations between LLMs …

Unpacking Open Source Bio, Jorge L. Contreras

Indiana Law Journal

For at least a quarter of a century, life science researchers around the world have undertaken initiatives loosely based on principles, goals, and institutional structures derived from the open source software (OSS) movement—approaches that I term “open source bio.” Yet open source bio lacks a clear definition and set of guiding principles. Given public calls for greater openness in life science research, it is useful to understand how open source bio projects have fared over the past quarter century: how they were structured, what they hoped to achieve, and, as social and policy experiments, whether or not they were successful. …

Discord And The Pentagon's Watchdog: Countering Extremism In The U.S. Military, Amy Gaudion

Indiana Law Journal

In his 2022 book, Ward Farnsworth crafts a metaphor from the lead-pipe theory for the fall of Rome to consider how rage and misinformation traveling through today’s technology-enabled pipes are poisoning our civic engagement and threatening our governmental structures: “We have built networks for the delivery of information––the internet, and especially social media. These networks too, are a marvel. But they also carry a kind of poison with them. The mind fed from those sources learns to subsist happily on quick reactions, easy certainties, one-liners, and rage.”1 This Article carries the metaphor into a new context and considers what should …

On Software Bugs And Legal Bugs: Product Liability In The Age Of Code, Asaf Lubin

Indiana Law Journal

Despite software’s ubiquity in modern life, its classification within product liability law remains unsettled. Is software a product, a service, a good, a component, a medium, a force, or something else altogether? Under the Restatement (Third) of Torts, a product is defined as a “tangible personal property distributed commercially for use or consumption.” But has this definition been embraced by states? And how has it been applied in the courts, since its adoption some twenty-six years ago?

Through a fifty-state survey and the canvassing of all relevant case law, this Essay reveals widespread doctrinal inconsistencies within the common law. Some …

Defragging Ownership: How Corporations Sliced, Diced, And Sold The Bundle, Joao Marinotti

Indiana Law Journal

Personal property ownership is in a precarious state, facing structural, economic, and legal assaults. As a result, the autonomy, security, and privacy that ownership once protected have been displaced by a tenuous reliance on opaque contractual arrangements and corporate goodwill. Owners no longer enjoy the unfettered right to access, use, and control their personal property. Through a range of seemingly unrelated business practices, companies have leveraged their growing power to disaggregate the property bundle into compartmentalized rights and privileges, which can then be individually licensed, leased, restricted, or even revoked. Purchases no longer mark the end of buyer-seller relationships; instead, …

Antimicrobial Activity In Auxin-Induced Formation Of In Vitro Culture- Derived Aloe Vera Roots, Eufrocinio Marfori, Bernadette Rapiz

The Philippine Agricultural Scientist

Aloe vera is a perennial, succulent plant which has been used in folk medicine for wound-healing, as its roots have been reported to exhibit remarkable antimicrobial properties. However, collecting the roots is detrimental to plant growth and development. Hence, an alternative system of producing A. vera roots must be developed. Tissue culture is a potential tool to obtain A. vera root biomass, which can serve as raw materials for the large-scale production of antimicrobial compounds. In this study, individual shoots taken from the multiple shoot culture of A. vera were induced to form roots in MS medium supplemented with 1 …

A Review On The Cytogenetic Integrity Of Micropropagated Plants [Review Paper], Eliaza Alumbro Peniton Jr

The Philippine Agricultural Scientist

Cytogenetic stability is essential for the survival of micropropagated plants. While micropropagation allows rapid propagation of plants with desirable phenotypes, it may also produce genetic variations that are, at times, cytogenetically observable. Factors affecting these variations are not fully understood, and micropropagation protocols are optimized to produce genetically stable regenerants. The genetic stability of micropropagated plants is traditionally assessed by comparing the phenomorphological traits of the regenerants to the mother plant. However, genetic variation does not often result in obvious morphological changes. Therefore, molecular and cytogenetic markers are typically used to evaluate the genetic variations of regenerants. Moreover, analyzing plant …

The Seduction Of Journalism In Atlanta: William Randolph Hearst And The Atlanta Georgian, Andrew J. Bramlett

The Kennesaw Journal of Undergraduate Research

The Atlanta Georgian was founded in 1906, quickly becoming a rival of the already established Atlanta Constitution and Atlanta Journal. Its founding editor, John Temple Graves, was a devoted believer of the New South Movement and a prominent ally of newspaper mogul William Randolph Hearst. In 1912, Hearst purchased the Georgian, expanding his influence into the South. The Georgian was a small piece of his grander plan to become President of the United States, and he quickly turned it into Atlanta’s most discussed newspaper. However, since the first edition of the Georgian was published in 1906, Hearst’s presence …

Familiarity Moderates Education Level Of Stigma For Professional Efficacy Of Treating Mental Illness, Jason J. Burrow-Sanchez, Shawnda Schroeder, Thomasine Heitkamp, Brian Urlacher, Sharon Cook, Paula Bennett, Carolina Corrales

Indigenous Health Faculty Publications

Background: About one in five adults in the United States experience any mental illness (AMI) whereas 14.2 million experience serious mental illness (SMI). The perception of stigma among these individuals can be associated with care seeking behavior and treatment adherence.

Purpose: Two factors that mitigate stigma are familiarity with someone experiencing AMI/SMI and general level of education. Heretofore, these factors have not been tested together to determine if familiarity moderates the relation between level of education and stigma of professional efficacy for treating mental illness.

Methods: In fall 2020, an online survey in the state of Utah measured 1,300 adults’ …
