Before Amplification: The Role Of Experts In The Dynamics Of The Social Attenuation And Amplification Of Risk, Lisbet Fjaeran, Kenneth Pettersen Gould, Rob Goble Jan 2024

Before Amplification: The Role Of Experts In The Dynamics Of The Social Attenuation And Amplification Of Risk, Lisbet Fjaeran, Kenneth Pettersen Gould, Rob Goble

Sustainability and Social Justice

In this article, we use system/network theory together with the social amplification of risk framework (SARF) to show how expert actors over time and across multiple events can contribute to social risk amplification and attenuation. The framework and the theory, in particular the concepts of risk emplacement and displacement, are employed in the analysis of an illustrative case related to the use of the feed additive, narasin, and provide explanations of how risks are part of continuously ongoing and dynamic social processes. By emphasizing the role of experts in such developments, connecting what happens in expert communities with the processing …

Finding pathways to more sustainable agriculture and resource use remains the most pressing challenge for Amazonian countries. Characterizing recent changes in the structure and types of agrarian production systems, this review identifies responses to deal with the challenges and opportunities to promote more sustainable production and extraction economies in the Amazon. While regional agriculture and resource economies rest on a rich diversity of producers, knowledge, and production systems, the expansion of agribusiness enterprises has come to dominate the distribution of subsidies, institutional support, and logistical infrastructure. These trends are associated with forest loss and degradation, pollution of waterways, pressures on …

Motion And Teleportation Of Polar Bubbles In Low-Dimensional Ferroelectrics, S. Prohorenko, Y. Nahas, V. Govinden, Q. Zhang, N. Valanoor, L. Bellaiche Jan 2024

Motion And Teleportation Of Polar Bubbles In Low-Dimensional Ferroelectrics, S. Prohorenko, Y. Nahas, V. Govinden, Q. Zhang, N. Valanoor, L. Bellaiche

Physics Faculty Publications and Presentations

Electric bubbles are sub-10nm spherical vortices of electric dipoles that can spontaneously form in ultra-thin ferroelectrics. While the static properties of electric bubbles are well established, little to nothing is known about the dynamics of these particle-like structures. Here, we reveal pathways to realizing both the spontaneous and controlled dynamics of electric bubbles in ultra-thin Pb(Zr0.4Ti0.6)O3 films. In low screening conditions, we find that electric bubbles exhibit thermally-driven chaotic motion giving rise to a liquid-like state. In the high screening regime, we show that bubbles remain static but can be continuously displaced by a local …

Ableist Microaggressions, Disability Characteristics, And Nondominant Identities, Melissa Deroche, Lee Za Ong, Jennifer M. Cook Jan 2024

Ableist Microaggressions, Disability Characteristics, And Nondominant Identities, Melissa Deroche, Lee Za Ong, Jennifer M. Cook

College of Education Faculty Research and Publications

Microaggressions are commonplace overt and covert forms of discrimination that convey disparaging messages to individuals who hold marginalized identities, including people with disabilities (PWD). Although PWD are a prevalent nondominant identity group in the United States, little is known about the occurrence of ableist microaggressions in this culturally diverse community, including how ableist microaggressions are experienced based on disability characteristics and other nondominant identities. A sample consisting of 201 PWD completed an electronic survey that examined the occurrence of ableist microaggressions based on visibility of disability, type of disability, and nondominant sociocultural identities. We found that PWD have a moderate …

The American Antimonopoly Tradition: Origins, Contradictions, Transformations, Daniel A. Crane Jan 2024

The American Antimonopoly Tradition: Origins, Contradictions, Transformations, Daniel A. Crane

Articles

Proponents of antitrust reform argue for the rediscovery of an American antimonopoly tradition that predated the Sherman Act by centuries and suggests the reimagination of a more robust contemporary policy against concentrated economic power. But historically there have been a number of distinct and often contradictory strands of American antimonopoly. The American colanists inherited a weak, recent, and largely invented antimonopoly common law tradition focused on exclusive grants of privilege from the crown. In the nineteenth century, antimonopoly became a generative and ubiquitous concept in state legislatures and courts, but one with multiple, inconsistent meanings that evolved in the decades …

Improving Growth Models Of Cultivated Sugar Kelp, Saccharina Latissima, By Accounting For Intraspecific Variation In Thermal Tolerance, Ruby Krasnow, Sara Gonzalez, Scott Lindell Jan 2024

Improving Growth Models Of Cultivated Sugar Kelp, Saccharina Latissima, By Accounting For Intraspecific Variation In Thermal Tolerance, Ruby Krasnow, Sara Gonzalez, Scott Lindell

Student Publications [Scholarly]

Dynamic models of sugar kelp (Saccharina latissima) growth are used to estimate the production potential of seaweed aquaculture in many regions around the world. These models do not currently account for the existence of S. latissima ecotypes that are adapted to regional environmental conditions, particularly temperature. We tested the hypothesis that recalibrating the temperature parameters of a dynamic energy budget model using literature data for S. latissima from regions with a similar climate to the region of interest would result in more accurate predictions than using a general species-wide temperature response curve. Calibrating the model using data from warm regions …

Grappling With Real Property Supremacy In Us Urban Climate Finance, Julia Wagner, Mark Kear, Sarah Knuth, Sahar Zavareh Hofmann, Zac E. Taylor Jan 2024

Grappling With Real Property Supremacy In Us Urban Climate Finance, Julia Wagner, Mark Kear, Sarah Knuth, Sahar Zavareh Hofmann, Zac E. Taylor

Student Publications [Scholarly]

In US cities, drives to secure property value against climate risks have become a preoccupation for mainstream climate finance. This real property bias sidelines non-owners and inhabitants of historically marginalized housing types, limiting their capacity to prepare for and recover from climate change events. In this intervention, we survey major pathways of existing climate finance, before turning to emerging trends for residential ‘climate-proofing,’ retrofitting efforts that bring climate finance ‘home’ to the building level. Building on the concept of ‘real property supremacy,’ we demonstrate how resourcing climate response is limited by the privileging of real property in the structure and …

Literature And The Law, Melissa J. Ganz Jan 2024

Literature And The Law, Melissa J. Ganz

English Faculty Research and Publications

The law underwent significant changes in eighteenth-century Britain. Although these changes resulted in an expansion of rights and freedoms for some British subjects, the liberalization of the law was far from complete. This chapter considers how writers working in a range of genres revealed the limits of the law, focusing on debates about the nature and ends of criminal justice, the legal regulation of marriage, and the legality of slavery and the slave trade. In different ways and to different degrees, the chapter shows, writers challenged and reimagined the inequalities inscribed in and fostered by the legal system.

The Impact Of Low-Head Dams On Freshwater Turtle Species Assemblages, Sarah Simmons Jan 2024

The Impact Of Low-Head Dams On Freshwater Turtle Species Assemblages, Sarah Simmons

All-Inclusive List of Electronic Theses and Dissertations

Turtles are an important component of many freshwater ecosystems, yet the impact of dams on freshwater turtles is an understudied topic globally. Past studies have focused on large dams and there is no literature addressing the impact of dams on turtle species assemblages. Dams affect turtles and their habitat by altering water flow, ecological communities, nesting and basking sites, and overwintering sites, and restricting turtle movements. Indiana has many low-head dams that no longer serve their original function, are in disrepair, and are hazardous to kayakers. There are ongoing efforts to remove these dams to improve stream ecology and safety. …

Understanding The Overall Health Of Midwestern Bats, Nicole Castaneda

All-Inclusive List of Electronic Theses and Dissertations

The overall health of an individual or population can be measured in various ways. This research investigates bat health and reports baseline values of 1) hematological measures, 2) ectoparasite and endoparasite indices, and 3) prevalence of a zoonotic bacterium Bartonella , in four bat species, including big brown bat ( Eptesicus fuscus ), eastern red bat ( Lasiurus borealis ), Indiana bat ( Myotis sodalis ), and the evening bat ( Nycticeius humeralis ) that I captured at six state-protected sites in northeastern Missouri, USA over three summers. Such baseline values are needed, for example, when comparing diseased and stressed …

Although sex determination is ubiquitous in vertebrates, mechanisms of sex determination vary from environmentally to genetically influenced. In vertebrates, genetic sex determination is typically accomplished with sex chromosomes. Groups like mammals maintain conserved sex chromosome systems, while sex chromosomes in most vertebrate clades are not conserved across similar evolutionary timescales. One group inferred to have an evolutionarily stable mode of sex determination is Anguimorpha, a clade of charismatic taxa including monitor lizards, Gila monsters, and crocodile lizards. The common ancestor of extant anguimorphs possessed a ZW system that has been retained across the clade. However, the sex chromosome system in …

Stress Biology: Complexity And Multifariousness In Health And Disease, Emily M. Sontag Jan 2024

Stress Biology: Complexity And Multifariousness In Health And Disease, Emily M. Sontag

Biological Sciences Faculty Research and Publications

Preserving and regulating cellular homeostasis in the light of changing environmental conditions or developmental processes is of pivotal importance for single cellular and multicellular organisms alike. To counteract an imbalance in cellular homeostasis transcriptional programs evolved, called the heat shock response, unfolded protein response, and integrated stress response, that act cell-autonomously in most cells but in multicellular organisms are subjected to cell-nonautonomous regulation. These transcriptional programs downregulate the expression of most genes but increase the expression of heat shock genes, including genes encoding molecular chaperones and proteases, proteins involved in the repair of stress-induced damage to macromolecules and cellular structures. …

Making Sense Of 303 Creative: A Free Speech Solution In Search Of A Problem, David S. Schwartz Jan 2024

Making Sense Of 303 Creative: A Free Speech Solution In Search Of A Problem, David S. Schwartz

Constitutional Commentary, Vol. 37 and later (2023–present)

In 303 Creative v. Elenis, the Supreme Court held that a website designer had a First Amendment right to refuse to create wedding websites for same-sex couples, even though she would create such websites for opposite-sex couples and despite the fact that her refusal violated a Colorado antidiscrimination law. 303 Creative purports to resolve a tension between freedom of speech and public accommodations laws as applied to “creative professionals” whose products or services are expressive. But this problem is largely theoretical. It did not really exist outside a small handful of ginned-up controversies between purportedly creative wedding-related businesses run by …

The Volokh Briefs: Drawing The Line Against Compelled Speech In Public Accommodations, Dale Carpenter

Constitutional Commentary, Vol. 37 and later (2023–present)

Although I generally support the result in 303 Creative, my aim here is neither to fully explain nor to defend the decision. That’s a project for another day. Instead, in this symposium commemorating Professor Volokh’s work, my aim is to outline the legal position he developed, which aligned with and may have influenced the decision. I’ll focus on what I believe are the most important briefs in three key cases: Elane Photography (2013), Masterpiece Cakeshop (2018), and 303 Creative (2023) itself. Collectively, I’ll refer to these as “the Volokh briefs.” While others contributed, Volokh and his First Amendment amicus clinic …

The development of gadolinium-based contrast agents (GBCAs) has been pivotal in advancing magnetic resonance imaging (MRI), offering enhanced soft tissue contrast without ionizing radiation exposure. Despite their widespread clinical use, the need for improved GBCAs has led to innovations in ligand chemistry and polymer science. We report a novel approach using methacrylate-functionalized DO3A ligands to synthesize a series of copolymers through direct reversible addition-fragmentation chain transfer (RAFT) polymerization. This technique enables precise control over the gadolinium content within the polymers, circumventing the need for subsequent conjugation and purification steps, and facilitates the addition of other components such as targeting ligands. …

Aberrant DNA repair is a hallmark of cancer, and many tumors display reduced DNA repair capacities that sensitize them to genotoxins. Here, we demonstrate that the differential DNA repair capacities of healthy and transformed tissue may be exploited to obtain highly selective chemotherapies. We show that the novel N3-(2-fluoroethyl)imidazotetrazine “KL-50” is a selective toxin toward tumors that lack the DNA repair protein O6-methylguanine-DNA-methyltransferase (MGMT), which reverses the formation of O6-alkylguanine lesions. We establish that KL-50 generates DNA interstrand cross-links (ICLs) by a multistep process comprising DNA alkylation to generate an O6-(2-fluoroethyl)guanine (O6FEtG) …

Effects Of Dehumanization And Disgust-Eliciting Language On Attitudes Toward Immigration: A Sentiment Analysis Of Twitter Data, Katherine S. Wahrer, Cynthia J. Najdowski, John V. Passarelli Jan 2024

Effects Of Dehumanization And Disgust-Eliciting Language On Attitudes Toward Immigration: A Sentiment Analysis Of Twitter Data, Katherine S. Wahrer, Cynthia J. Najdowski, John V. Passarelli

Psychology Faculty Scholarship

Attitudes towards immigration have been shown to be driven by dehumanization and disgust. The more people dehumanize immigrants and the more disgusted they feel, the more negative attitudes they tend to have toward immigrants. However, little is known about how exposure to social media content that links dehumanization, disgust, and immigration influences users’ attitudes on this issue. This is important to consider because the majority of adults in the United States are on social media. We used Twitter data, machine learning, and sentiment analysis to investigate whether exposure to dehumanizing or disgust-eliciting tweets about immigration impacts users’ own sentiment toward …

An Examination Of The Visual And Textual Influences On The Anthology Of American Folk Music, Ben Collier Jan 2024

An Examination Of The Visual And Textual Influences On The Anthology Of American Folk Music, Ben Collier

History Theses

The Anthology of American Folk Music is a collection of eight-four selections of southern vernacular recordings made for commercial record labels in the 1920s and 1930s and assembled into a unified collage by Harry Smith. Smith was an experimental filmmaker, painter, and self-taught anthropologist with a deep interest in renaissance hermeticism and mysticism who worked with Moe Asch in 1952 to release the six-record set and accompanying handbook on Folkways Records. The release was heralded by musicians and critics as an essential piece of influence on the folk music revival. Despite this, the Anthology sold poorly and quickly faced legal …

Department of Teaching, Learning, and Teacher Education: Faculty Publications

Labor unions in the United States have experienced decades of decline, but recent years have seen a rebirth of union campaigns and successes. Because unions are once again becoming a threat to large companies, it is reasonable to assume that efforts to discourage organizing efforts will increase and become even more robust in the near future. Although traditionally, companies have worked to suspend union organizing through captive audience meetings in which unions were discussed via verbal or written modes, more recent means of reaching workers with anti-union messages incorporate a variety of communication strategies to get the message across.

Herbivores play a crucial role in shaping tundra ecosystems through their effects on vegetation, nutrient cycling, and soil abiotic factors. Understanding their habitat use, co-occurrence, and overlap is therefore essential for informing ecosystem-based management and conservation. In the High Arctic, only a marginal proportion of the land area is vegetated, and climate change is impacting herbivore population sizes and their habitats. In this study, we assessed the spatial habitat overlap of a vertebrate herbivore community based on: 1) regional predictive summer habitat suitability models for the resident Svalbard reindeer (Rangifer tarandus platyrhynchus), resident Svalbard rock ptarmigan (Lagopus …

The relationship between biodiversity and ecosystem function (BEF) captivates ecologists, but the factors responsible for the direction of this relationship remain unclear. While higher ecosystem functioning at higher biodiversity levels (‘positive BEF’) is not universal in nature, negative BEF relationships seem puzzlingly rare. Here, we develop a dynamical consumer-resource model inspired by microbial decomposer communities in pitcher plant leaves to investigate BEF. We manipulate microbial diversity via controlled colonization and measure their function as total ammonia production. We test how niche partitioning among bacteria and other ecological processes influence BEF in the leaves. We find that a negative BEF can …
