Recontextualizing Engagement With Data Visualizations In The Context Of The Socio-Ecological, Eva Thanheiser, Laurie Rubel, Beth Herbel-Eisenmann, Courtney Koestler Jan 2025

Recontextualizing Engagement With Data Visualizations In The Context Of The Socio-Ecological, Eva Thanheiser, Laurie Rubel, Beth Herbel-Eisenmann, Courtney Koestler

Mathematics and Statistics Faculty Publications and Presentations

We explore how data visualizations (DVs) are representational tools that can be used to narrate certain aspects of a context but silence others. Using multiple DVs allows for contrasting the DVs and likely provides opportunities for critical reading and exploring the entanglement of political and ecological dimensions of an issue. We start by integrating two sets of practices, Notice, Wonder, Feel, Act and Reimagine (NW-FAR) (Kahn, et al., 2022) and critical graph reading, Framing, Formatting, Narrating (FFN) (Rubel, et al., 2021) towards taking a socio-political stance and supporting students to read data visualizations and develop critical data literacy. We look …

Physicists As Environmental Experts, Rachel Rothschild Jan 2025

Physicists As Environmental Experts, Rachel Rothschild

Articles

The question of which scientists are qualified to provide expert guidance in legal controversies is a perennial debate among scholars, judges, and lawyers. Scientists who participate in legal disputes can achieve enormous power and influence, not only over the case at hand but over long-term developments in legal doctrine. While these issues arise in many areas of the law, environmental litigation has been a particularly active site of contestations over epistemic authority. Courts have frequently relied on scientists to understand whether the government is justified in regulating pollution and who may be liable for environmental and public health harms.

The Transnationalisation Of Civil Society In East Asia’S War Redress Movement, Timothy Webster Jan 2025

The Transnationalisation Of Civil Society In East Asia’S War Redress Movement, Timothy Webster

Faculty Scholarship

Transnational human rights litigation is commonly associated with developments in Europe and the Americas during the 1990s. But Asian actors have used legal mobilisation to hold corporate actors to account since at least the 1970s. This chapter charts the first usages of transnational litigation in East Asia’s Word War II redress movement, akin to the Holocaust Restitution movement of the West. Korean and Chinese forced labourers liaised with Japanese attorneys, activists and academics to press compensation claims against Japanese corporations for wartime human rights abuses in Tokyo. Legal mobilisation did not succeed in the traditional sense. Yet, the formation of …


Creative Energies: Unearthing The Role Of Romantic Ecocriticism, Nicole Marie Chambers-Stahl Jan 2025

Creative Energies: Unearthing The Role Of Romantic Ecocriticism, Nicole Marie Chambers-Stahl

Graduate Theses, Dissertations, and Problem Reports (ETD)

The literary field of ecocriticism has transcended the boundaries of Academia: excited to connect to their physical environments, many of these scholars are focusing on genres like place-based writing, rhetoric of energy policy, and representations of the Earth in film and media. Interdisciplinary by nature, ecocriticism has demonstrated clear potential in its ability to intersect with concentrations like the history of science, animal studies, and environmental justice.

However, as the language around global crises is heating up —“Today it is scientists, not prophets,” writes Tobias Menely in “‘The Present Obfuscation,’” “who speak the language of apocalypse” (478)—ecocritical scholarship is at …


The People Of The North: Influencer Histories And Miniaturization In Eleventh-Century Italy, Evan Anthony Simonetti Jan 2025

The People Of The North: Influencer Histories And Miniaturization In Eleventh-Century Italy, Evan Anthony Simonetti

Graduate Theses, Dissertations, and Problem Reports (ETD)

The Norman invasion of Italy in the eleventh century was a process that required political support and legitimacy for its leaders, the Hauteville dynasty. The members of this dynasty either commissioned or financed three individuals as they wrote three respective histories of the Norman conquest in order to accomplish this legitimation. In these sources, each author took inspiration from the classic works of history and poetry of the Greek and Roman world and applied symbolism and direction from their understanding of medieval Christian theology. In addition, these works catalogued examples of events, people, places, animals, and behavior as exotic objects …


Behavioral Effects Of Prenatal Ecig Aerosol Exposure On Sprague-Dawley Rats, Erin Elizabeth Wylie Jan 2025

Behavioral Effects Of Prenatal Ecig Aerosol Exposure On Sprague-Dawley Rats, Erin Elizabeth Wylie

Graduate Theses, Dissertations, and Problem Reports (ETD)

Maternal electronic cigarette (ECIG) use during pregnancy raises concerns about potential risks to offspring, yet its behavioral effects remain unclear. The present studies were designed to investigate how prenatal exposure to ECIG aerosols, with and without nicotine, influences the behavior of Sprague-Dawley rat offspring. Dams were exposed to aerosols containing base liquid alone, aerosols containing base liquid with 18 mg/ml nicotine, or filtered air (control) throughout gestation. Following postnatal day 65, male offspring from 17 litters completed lever-press acquisition (Experiment 1), sustained-attending (Experiment 2), and nicotine self-administration (Experiment 3) tasks. One-way analyses of variance (ANOVAs) were used to compare task …

New Treaty Law On Autonomous Weapons? An Opportunity To Reframe The Discourse, Laurie R. Blank Jan 2025

New Treaty Law On Autonomous Weapons? An Opportunity To Reframe The Discourse, Laurie R. Blank

Case Western Reserve Journal of International Law

Calls for a new treaty for autonomous weapons—or for any other new technology—stem from a concern at the most basic level: the concern that LOAC’s existing treaties are not sufficient to fulfill their core purposes of protecting civilians and other vulnerable persons and regulating the conduct of hostilities. Could treaties drafted in 1949—when air power was new and space a distant dream, when the first operational computer ran its first program and navigation relied on the compass and sextant—be sufficient for the complexities and challenges of the electromagnetic spectrum, artificial intelligence, quantum mechanics, machine learning, cyber, anti-satellite weapons, and other …


Japanese Incarceration Memorial As Trauma Portfolio Play, A. J. Faas, Alyssa Singh, Cibella Gamma Jan 2025

Japanese Incarceration Memorial As Trauma Portfolio Play, A. J. Faas, Alyssa Singh, Cibella Gamma

Faculty Research, Scholarly, and Creative Activity

In collaboration with the Japanese American Museum of San José, California, we examined their exhibit of WWII-era incarceration of Japanese Americans to understand how the presentation of different positionalities (e.g., Japanese/American, loyal/disloyal) engage with and contest the terms of incarceration and internal politics within the Japanese American community. In our analysis, we focus on the reproduction and contestation of particular narratives of power and identity and treat the memorial exhibit as a variety of community-based “trauma portfolio” that unsettles state bureaucratic constructions of suffering and (in)justice. We conclude by identifying transformative possibilities for engaging with the different positionalities of incarcerated …


Unravelling The Ecological Trade-Offs In Behavioural And Physiological Sexual Traits, Alicia Eveson Jan 2025

Unravelling The Ecological Trade-Offs In Behavioural And Physiological Sexual Traits, Alicia Eveson

School of Biological and Marine Sciences Theses

Animals experience temporally and spatially heterogeneous environments throughout their lives. Therefore, individuals that are able to plastically adjust their behaviour to the current environment, are able to maximise their fitness. These behavioural adjustments are particularly important where there are trade-offs between investment in different life-history traits. Trade-offs between reproduction and survival have been widely documented, in addition to a body of evidence for trade-offs between mating related traits. How an individual adjusts their mating behaviour in response to their social and biotic environments are important aspects of selection. Changes in the social environment, including sex ratio or population density changes, …


Development Of Welfare Assessment Strategies For Indonesian Zoos, Yonathan Yonathan Jan 2025

Development Of Welfare Assessment Strategies For Indonesian Zoos, Yonathan Yonathan

School of Biological and Marine Sciences Theses

Animal welfare assessment is a core element of zoo management, helping zoos achieve positive welfare state for their animals. Welfare should be assessed regularly to evaluate, monitor, and improve the standards of care. The research on welfare assessment and its development process increased after the World Association of Zoos and Aquariums (WAZA) launched the 2023 Animal Welfare Goals, which include mandatory welfare assessment process for national and regional zoo associations. In Indonesia, many zoos don’t have their own welfare assessment and find it difficult to adapt generic tools due to variation in husbandry, resources, and facilities. This project aims to …


How Do Human-Induced Environmental Stressors Shape The Distribution, Physiology, And Behaviour Of The Lemur Leaf Frog?, Benjamin Hough Jan 2025

How Do Human-Induced Environmental Stressors Shape The Distribution, Physiology, And Behaviour Of The Lemur Leaf Frog?, Benjamin Hough

School of Biological and Marine Sciences Theses

The Lemur leaf frog (Agalychnis lemur) is a critically endangered species of anuran whose survival is increasingly threatened by human-induced environmental stressors, such as habitat loss, fragmentation, and climate change. This study investigates how those stressors shape the physiology, distribution, and behaviour of the species through combinations of physiological and distributional modelling and a behavioural trial. The study uses a novel approach into understanding how future risk posed by climate change could impact Lemur leaf frogs. By using field spatial data combined with physiological mechanistic modelling, the study is able to predict how Lemur leaf frogs body temperature and geographical …

To address the need for well-characterised probiotic strains for tilapia and carp aquaculture, this study investigated the isolation, characterisation, and application of host-derived candidate probiotics from Nile tilapia (Oreochromis niloticus) and mirror carp (Cyprinus carpio), and their influence on growth, feed utilisation, intestinal integrity and microbiome, and mucosal health of the host.A total of 263 intestinal bacterial isolates were screened in vitro for antagonism against Aeromonas hydrophila and Streptococcus iniae. The top 31 isolates with inhibitory effects underwent screening against three further fish pathogens and were assessed for haemolytic activity and extracellular enzyme production in …


Evaluating The Efficacy Of Brewers’ Yeast-Derived Functional Feed Additives In Mitigating Soybean Meal-Induced Enteritis In Atlantic Salmon, Taofik Adeiza Momoh Jan 2025

Evaluating The Efficacy Of Brewers’ Yeast-Derived Functional Feed Additives In Mitigating Soybean Meal-Induced Enteritis In Atlantic Salmon, Taofik Adeiza Momoh

School of Biological and Marine Sciences Theses

Aquaculture continues to expand as a vital contributor to global food security, yet this growth introduces new challenges including the need to replace fishmeal with plant-based ingredients without compromising intestinal health. In Atlantic salmon aquaculture, one of the main constraints to plant protein inclusion is soybean meal-induced enteritis (SBMIE), a diet-related inflammatory condition that impairs mucosal function. Meanwhile, the use of functional feed additives such as those derived from brewers’ yeast (Saccharomyces cerevisiae) have emerged as a promising strategy to mitigate such diet-induced pathologies and support immune regulation. This thesis investigates the efficacy of structurally distinct brewers’ yeast-derived additives, including …


Considering Behaviour In Genetic Sampling – A Case Study With Grey Seals, Kathryn Wiltshire Jan 2025

Considering Behaviour In Genetic Sampling – A Case Study With Grey Seals, Kathryn Wiltshire

School of Biological and Marine Sciences Theses

Genetic variations are increasingly linked to intra-specific behavioural variations. Advancing our knowledge of behavioural genetics could make screening populations for genetic polymorphisms associated with behavioural variations possible. Genetic-behaviour links have been increasingly discovered in terrestrial mammals, but there are few comparable studies in marine mammals. Developing efficient and cost-effective genetic sampling techniques is essential to allow more studies on behavioural genetics in lesser researched marine mammals. This study explores the potential of a sampling technique, still in its infancy in marine mammal studies, that has potential to cause minimal stress to the animals. Buccal swabs were tested in a group …

Dynamically Scaling Biomimetic Robots Through Parallel Viscoelastic Actuators, Foster Olaf Holmquist Jan 2025

Dynamically Scaling Biomimetic Robots Through Parallel Viscoelastic Actuators, Foster Olaf Holmquist

Graduate Theses, Dissertations, and Problem Reports (ETD)

Robots provide a unique proving ground for testing scientists’ understanding of neuromuscular systems. Synergistically, mimicking biological control laws and mechanics could offer robotics the robust and adaptive locomotion of animals. Previous work has utilized the wealth of research on insect biomechanics to develop scaled robotic models but doing so presented a problem: while these robots’ larger scale has simplified manufacturing, the scale has also shifted its mechanics from those of the modeled organisms. While animals walk, forces are generated that describe their mechanics and influence motor control. The musculoskeletal structure and stretch of muscles result in viscous and elastic forces, …


The Effect Of Cerebellar Feedback On The Spatial Processing Of Conspecific Signals In The Electrosensory System, Dakota Ray Miller Jan 2025

The Effect Of Cerebellar Feedback On The Spatial Processing Of Conspecific Signals In The Electrosensory System, Dakota Ray Miller

Graduate Theses, Dissertations, and Problem Reports (ETD)

Animals have evolved sensory systems to help decipher important environmental signals that are vital for their survival. Feedback pathways are necessary to allow these signals to stand out in a noisy background, enabling the animal to focus on them more effectively. The electrosensory system of Apteronotus leptorhynchus allows the fish to sense the modulations caused by other conspecifics to allow for proper responses during social interactions. Electroreceptors detect these EODs, and afferent nerves project these signals to the ELL, where electrosensory information is projected to other parts of the brain. Cerebellar feedback to the ELL allows the suppression of lower …

Rabinovici, Rosa Rademakers, Rema Raman

Biostatistics Faculty Publications

Limbic predominant age-related TDP-43 encephalopathy neuropathologic change (LATE-NC) is highly prevalent in late life and a common co-pathology with Alzheimer's disease neuropathologic change (ADNC). LATE-NC is a slowly progressive, amnestic clinical syndrome. Alternatively, when present with ADNC, LATE-NC is associated with a more rapid course. With the emergence of anti-amyloid therapeutics, discrimination of LATE-NC from ADNC is critical and will lead to greater clinical recognition of amnestic patients without ADNC. Furthermore, co-pathology with LATE-NC may influence outcomes of these therapeutics. Thus there is a need to identify patients during life with likely LATE-NC. We propose criteria for clinical diagnosis of …

Intergenerational Arts In The Classroom: A Win-Win, Audrey Klunenberg Jan 2025

Intergenerational Arts In The Classroom: A Win-Win, Audrey Klunenberg

Graduate Research Papers

This paper suggests that intergenerational arts programs, particularly those conducted in public schools, can help participants build empathy, a sense of community and belonging. Evidence of these changes was collected through informal observations during three intergenerational art classes in a first grade classroom, as well as through discussions with participants before and after their participation in the intergenerational arts programming. Empathy and community can be built through carefully planned collaborative art-making opportunities and the effect can be evidenced in the forming of relationships, the absence of behavioral problems, and the building of the facilitator’s personal network. The paper concludes that …


Black Girls In School: The Harmful Effects Of Dehumanization And Disciplinary Inequities, Annika Peterson Jan 2025

Black Girls In School: The Harmful Effects Of Dehumanization And Disciplinary Inequities, Annika Peterson

Graduate Research Papers

Black girls in the U.S. experience dehumanization through adultification and sexual objectification that impact disciplinary practices in the education system. Adultification stereotypes Black girls as more mature, less innocent, and less in need of protection, which results in harsher disciplinary actions and limited empathy from educators. At the same time, sexual objectification reinforces harmful perceptions of Black girls' sexuality and culpability in their sexual violence victimization. The “Jezebel” and “Angry Black Woman” stereotypes continue to influence how Black girls are perceived as either hypersexual or aggressive. These biases and stereotypes contribute to disproportionate disciplinary measures, particularly subjective infractions like “defiance” …

Implementation And Performance Evaluation Of Plastic Road Mix Design In Parking Lot, Ishraq Faruk Jan 2025

Implementation And Performance Evaluation Of Plastic Road Mix Design In Parking Lot, Ishraq Faruk

Civil Engineering Dissertations - Archive

The uncontrolled proliferation of plastic waste has emerged as a global environmental crisis, with high-density polyethylene (HDPE) constituting a substantial fraction of the waste stream due to its extensive use in packaging and its resistance to degradation. In parallel, asphalt pavements particularly in urban infrastructure such as parking lots experience accelerated deterioration from raveling, rutting, and cracking as a result of thermal cycling, repetitive loading, and inadequate drainage. These converging challenges present an opportunity for innovative, circular-economy-based sustainable pavement technologies that simultaneously improve surface durability and mitigate plastic waste accumulation.

This research investigates the full-scale implementation and monitoring of HDPE …
