Rethinking The Canon: A Conceptual History Of The Layered Foundations Of Western Politics, Dembael Seidi, Muhammad Andi Firmansyah
Rethinking The Canon: A Conceptual History Of The Layered Foundations Of Western Politics, Dembael Seidi, Muhammad Andi Firmansyah
Jurnal Wacana Politik
Many accounts of Western political history suggest a direct, straight line from Ancient Greece to modern democracy. This article argues that this “Great Books” narrative is a myth that ignores how political ideas actually change over time. Using Reinhart Koselleck’s Begriffsgeschichte (conceptual history) framework, we demonstrate that key terms such as “law” and “citizenship” were not merely preserved but fundamentally transformed as they moved through Greco-Roman, Islamic, and Judeo-Christian civilizations. We call this transformation “conceptual alchemy”: a series of semantic translations through which Greek rationalism was retheorized via Islamic metaphysics and later synthesized by medieval scholasticism. Consequently, rather than a …
Investigation Of Environmental Influences On Multiple Sclerosis: A Study For Egypt’S Health, Noha Ezzaldin Alziny Ali
Investigation Of Environmental Influences On Multiple Sclerosis: A Study For Egypt’S Health, Noha Ezzaldin Alziny Ali
Theses and Dissertations
Background: Multiple sclerosis (MS) is a complex, chronic neuroinflammatory disease influenced by both genetic and environmental factors. While global research has identified potential environmental influences, most evidence comes from Western populations, creating a significant knowledge gap for regions like Egypt, which has witnessed a dramatic rise in MS prevalence over recent decades. This study hypothesized that Egyptian MS patients exhibit a distinct biological signature in their blood, characterized by an imbalance in essential and toxic trace elements (the metallome) and alterations in stress-response biomarkers associated with neuroaxonal injury and cellular stress. Objective: This study aimed to comprehensively profile and compare …
Perceptual And Geometric Advances In Crowd Simulation, Bilas Talukdar
Perceptual And Geometric Advances In Crowd Simulation, Bilas Talukdar
Dissertations
Simulating realistic crowd motion remains a fundamental challenge in computer graphics and multi-agent systems, as it requires modeling both physically plausible interactions and perceptually natural behaviors. Existing crowd simulation methods typically employ simplified geometric abstractions, most commonly circular agent representations, and model navigation using either analytical interaction formulations (e.g., force, velocity, or constraint-based methods) or learned policies derived through reinforcement learning. Despite their effectiveness, these approaches often overlook detailed geometric structure and do not explicitly account for perceptual realism. This dissertation addresses these challenges by improving the realism of virtual crowd simulation through two key advancements: perceptual preference learning and …
Membrane-Engineered Nanotherapeutic Platforms For Drug Delivery: Hollow Fiber Membrane Synthesis Of Lipid Nanoparticles, Biomimetic Nanocarriers, And Nanobubbles, Zhixiang Liu
Dissertations
Lipid-based nanocarriers have emerged as a cornerstone technology for RNA therapeutics, enabling effective intracellular delivery for applications ranging from vaccination to gene regulation. However, current manufacturing approaches, particularly microfluidic-based platforms, face inherent limitations in scalability, throughput, and structural tunability due to their reliance on confined channel geometries and restricted mixing architectures. Addressing these challenges requires fundamentally new strategies that decouple nanoparticle formation from traditional microscale flow constraints while maintaining precise control over physicochemical properties.
This dissertation presents a comprehensive framework for the design, engineering, and application of advanced lipid-based nanocarriers, centered on a hollow fiber membrane (HFM)—assisted nanopore-mediated assembly platform. …
Transcranial Ac Modulation Of Cerebellar Nuclear Activity In Awake Animals, Nuran Kavakli
Transcranial Ac Modulation Of Cerebellar Nuclear Activity In Awake Animals, Nuran Kavakli
Dissertations
Entrainment of cerebellar nuclear (CN) cells via cerebellar transcranial alternating current stimulation (ctACS) has been reported in animals under ketamine/xylazine anesthesia. Our main objective was to demonstrate modulation of CN activity in unanesthetized, freely moving animals using ctACS. Multi-channel carbon-fiber electrodes were implanted into the interpositus nucleus for recording multi-unit (MU) activity, and thin-film electrodes were implanted subcutaneously over the posterior cerebellum for stimulation. A frequency-domain-based metric was developed to quantify modulation from MU signals. The results demonstrated modulation in a wide range of frequencies (4 Hz-300 Hz) as in anesthetized animals. In contrast, the amplitude of the peak in …
Empowering Lifelong Choice: Supporting Older Individuals With Idd To Thrive At Work, Transition To Retirement With Dignity, And Maintain Community Connections, Leslie Quarles
Critical and Creative Thinking Capstones Collection
This synthesis addresses the need to support older individuals with intellectual and developmental disabilities in their engagement in continued work. The project traces the journey from an initial focus on supporting older individuals with intellectual and developmental disabilities to work as long as they wish to an eventual shift toward a phased retirement approach. It considers issues such as a reimagined visualization of the support team structure, integration of tailored job supports and Community Life Engagement (CLE). The author's familial history sparked a sense of injustice that would not stay buried, shaping a career path in disability services and access. …
Small Molecule Antioxidants As Potential Therapeutics For Preeclampsia, Maxim Mastyugin
Small Molecule Antioxidants As Potential Therapeutics For Preeclampsia, Maxim Mastyugin
Graduate Doctoral Dissertations
The major goal of this work was to develop a therapeutic intervention against preeclampsia (PE). Preeclampsia affects up to 5-7% of all pregnancies and has no causative treatments. It is associated with oxidative stress caused by a prolonged ischemic state and increase in reactive oxygen species (ROS) in the placenta. The cardinal symptoms include high blood pressure, kidney dysfunction, and in severe cases, eclampsia. With no treatment for the underlying causes available, we offer small molecule antioxidants which may scavenge ROS in the placenta arising from the initiating event of PE, the oxidative stress. By reducing placental ROS, these antioxidants …
The Cultivation Of Public Perception: Cultivated Meat Narratives And Misinformation On Tiktok, Anna M. Balkus
The Cultivation Of Public Perception: Cultivated Meat Narratives And Misinformation On Tiktok, Anna M. Balkus
Graduate Masters Theses
Cultivated meat is an emerging tissue engineering technology that has the potential to address major issues threatening food systems, including climate change, rapid population growth, and the spread of disease. Among technical challenges, public perception remains a significant barrier for the widespread adoption of cultivated meat. While social media has transformed communication globally, it has simultaneously contributed to corrupt online environments infected with misinformation—unintentional inaccuracies that differ from disinformation, which is spread with the intent to mislead. The way the public receives and digests information regarding new food technologies, like cultivated meat, will be shaped by their social media environment. …

Arts On The Point: Boston's First Public Sculpture Park, Isabella Slonka
Arts On The Point: Boston's First Public Sculpture Park, Isabella Slonka
Honors College Theses
Led by the conviction that “a public campus needs public art,” Professor Paul Tucker founded UMass Boston’s Arts on the Point (AoP) sculpture park in 1997. Large-scale works by world-class contemporary artists including Sol LeWitt, Dennis Oppenheim, Luis Jiménez, Sheila Pepe, and Mark di Suvero were made accessible to students, served as teaching aids and attracted those outside of UMB to Columbia Point. AoP’s use of long term loans made the landscape itself a rotating gallery.
Consideration of the “personality” of the campus was essential in the selection of works. Site visits with artists were conducted to ensure that their …

Michigan Tech Publications
Tissue engineering is widely used in research for investigating cellular proliferation, behavior, and responses to various stimuli. However, the predictive value of preclinical studies using cell culture plates is limited by the inability to recapitulate the complexity of the physiological microenvironment. Synthetic three-dimensional (3D) scaffolds can be engineered to mimic the complex morphology of the extracellular matrix of native tissues and can serve as physiologically relevant platforms for preclinical studies. In this study, 3D electrospun scaffolds were characterized to aid in breast cancer research. Unlike previous studies that focused primarily on scaffold fabrication or cell viability, this work systematically evaluates …
"It's Such A Natural Fit": Integrating Reggio Emilia And Head Start For Emergent Multilinguals, Christina Bohr
"It's Such A Natural Fit": Integrating Reggio Emilia And Head Start For Emergent Multilinguals, Christina Bohr
Graduate Doctoral Dissertations
Early childhood education classrooms reflect the increasing cultural and linguistic diversity of the United States where many children are raised speaking more than one language. Teachers in the early education field play a critical role in supporting children’s development of language and identity. Head Start, who serves a large population of emergent multilinguals (mls), plays an essential role in offering learning environments that foster language development in both English and their home language, among many other critical skills. The Reggio Emilia philosophy is a child-centered and community-oriented approach that promotes children’s independence, exploration, and intellectual development, and is frequently integrated …
Pickleweed In The Disappearing Marsh: Population Genetics & Metal Accumulation In Salicornia Depressa, Alice Kaisla
Pickleweed In The Disappearing Marsh: Population Genetics & Metal Accumulation In Salicornia Depressa, Alice Kaisla
Graduate Doctoral Dissertations
Salicornia is a genus of succulent halophytes found in salt marshes around the world. Salicornia species have a remarkably high tolerance for heavy metal pollution and have been shown to accumulate high concentrations of heavy metals in their tissue under experimental conditions. As a result, they are both a useful system for studying evolution in polluted coastlines and a potential candidate for use in phytoremediation. My research focuses on Salicornia depressa, known as pickleweed, a species commonly found in marshes along the heavily urbanized and industrialized New England coast. I investigate genetic diversity and population structure in S. depressa populations …

Making Kinship With Plants And The Multiple Meanings Of Care In Amazonian Indigenous Gardens, Ana Gabriela Morim De Lima
Making Kinship With Plants And The Multiple Meanings Of Care In Amazonian Indigenous Gardens, Ana Gabriela Morim De Lima
Tipití: Journal of the Society for the Anthropology of Lowland South America
This paper focuses on the bonds of kinship and care between humans, cultivated plants, and other-than-human beings in Indigenous gardens, myths, rituals, and shamanism, across Lowland South America. Drawing on Krahô ethnography and a review of ethnological literature, it highlights the contributions of Americanist ethnology to wider debates about multispecies relation, particularly with regard to vegetal agency. By exploring the ambivalent meanings of care- such as “caring,” “raising,” and “nurturing,” as well as “being careful,” “having respect,” and “taking precautions”- I examine how kinship relations between humans and their cultivated plants are made through care and unmade through its absence …
Is Trimethylamine N-Oxide A Friend, Foe, Or Hormetic Agent In Patients With Parkinson’S Disease: A Focused Review Of One Microbial Metabolite, Abraham B. Alton
Is Trimethylamine N-Oxide A Friend, Foe, Or Hormetic Agent In Patients With Parkinson’S Disease: A Focused Review Of One Microbial Metabolite, Abraham B. Alton
Student Works
This review synthesizes recent literature examining trimethylamine N-oxide (TMAO) synthesis and its potential role in Parkinson’s Disease (PD) pathology. An increase in TMAO plasma and CSF concentration is associated with PD progression and severity. TMAO biosynthesis is a two-step process. First, precursors including carnitine and choline are converted to trimethylamine (TMA) by gut microbes. Second, TMAO is oxidized to TMAO in the liver. Once absorbed into circulation TMAO crosses the blood brain barrier and may influence PD disease pathology by increasing neuroinflammation and astrocyte activation and damaging the cerebral lymphatic system. These mechanisms may contribute to the cognitive and motor …
On The Brink Of Silence: Ethnographic Perspectives On Hunting And Forest Life Among The Awa Guajá In Eastern Amazonia, Uirá Garcia
On The Brink Of Silence: Ethnographic Perspectives On Hunting And Forest Life Among The Awa Guajá In Eastern Amazonia, Uirá Garcia
Tipití: Journal of the Society for the Anthropology of Lowland South America
The central theme of this article basically resides in the relationship established by indigenous peoples between their hunting practices and the forest. Indigenous ways of connecting ‘hunting’ and ‘forest’ necessarily pass through other modes of knowing, only marginally – if it all – dependent on vision. On the contrary, sounds, smells and even dreams are, for many South American indigenous collectives, more trustworthy indices than what the eye sees. This article divides into two parts. In the first, I set out the main ideas related to the anthropological study of hunting in Amazonia at a conceptual level. In the second, …
Between The Root And The Stem: On Women-Plant Relations, Predation And Familiarisation Among The Awajún (Upper Amazonas, Peru), Nils Haukeland Vedal
Between The Root And The Stem: On Women-Plant Relations, Predation And Familiarisation Among The Awajún (Upper Amazonas, Peru), Nils Haukeland Vedal
Tipití: Journal of the Society for the Anthropology of Lowland South America
What to do with the problem of predation? This is not only a conundrum for anthropologists working in what has become known as animist societies. The gardening activities of the Awajún people of northern Peru’s high jungle are modelled on the teachings of the original mother of cultivated plants, Núgkui, who granted the Awajún their cultivars. Yet gardening is not an easy matter. The manioc sprouts seek to suck the blood of gardeners unless they are treated correctly. This article explores how predation is constantly kept at bay through familiarisation practices in which garden plants are made into the vegetative …
Making Noise Through Law: Indigenous Legal Mobilisation Against A Power Plant In “French” Guiana, Pierre Auzerau
Making Noise Through Law: Indigenous Legal Mobilisation Against A Power Plant In “French” Guiana, Pierre Auzerau
Tipití: Journal of the Society for the Anthropology of Lowland South America
In so-called “French” Guiana, or Guyane, the Kali’na village of Atopo Wipi has fought for years against a hydrogen power plant being built on their land. Drawing on ethnographic fieldwork conducted between 2023 and 2024 in Guyane and Western Europe, where I collaborated with various stakeholders to support Atopo Wipi’s resistance to the power plant, my research focuses on the legal dimensions of the Kali’na’s struggle to protect their land. Specifically, this article examines how the Kali’na navigated different normative frameworks, including international human rights standards and French law, to fight the project. Through this analysis, I show how the …

The findings …
Can Behavioral Interventions Promote Health Equity In Pediatric Type 1 Diabetes? A Narrative Review Of Promising Treatments, Paul T. Enlow, Jaquelin Flores Garcia, Julia Price, Kristen A. Torres, David V. Wagner
Can Behavioral Interventions Promote Health Equity In Pediatric Type 1 Diabetes? A Narrative Review Of Promising Treatments, Paul T. Enlow, Jaquelin Flores Garcia, Julia Price, Kristen A. Torres, David V. Wagner
Department of Pediatrics Faculty Papers
Purpose of review: Synthesize data on whether existing behavioral interventions can improve health equity among youth with type 1 diabetes.
Recent findings: While existing behavioral interventions demonstrated efficacy in improving health and/or psychosocial outcomes, evidence that these same interventions may improve health equity were lacking. Most interventions were evaluated using predominantly White and affluent samples and some studies did not report on racial, ethnic, or sociodemographic characteristics of their sample. Only a few interventions have been adapted for youth from minoritized backgrounds. Recent multisystemic and technology/mHealth interventions recruited samples that were sociodemographically representative of youth experiencing disparities, suggesting that these …
“Ese Dia Que Se Va El Patron An Hecho Fiesta”.* Historicities Of Successful Resistance Against Hacienda Bosses Among The Kukama (Peru, 1933-1945), Arno R. Holl
Tipití: Journal of the Society for the Anthropology of Lowland South America
This paper analyzes two cases of resistance by Kukama workers within the debt slavery system of habilitación in the Peruvian Amazon during the first half of the twentieth century. It discusses the similarities and differences between the two cases, and positions the workers and their accounts of events and agency within the historical, social and cosmological framework of the time and region. Through the examples studied here, the hierarchies, power dynamics, spirituality, lifestyles, traditions, and cultural changes that shaped Kukama communities at the time become visible from an emic perspective. The paper places special emphasis on how historical events are …

Designing Captcha Systems With Reinforcement Learning For Adaptive Defense, Meghana Indukuri, Eman Naseerkhan, Joshua Rose, Martin Tran, Younghee Park
Faculty Research, Scholarly, and Creative Activity
CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) systems remain a widely deployed defense against automated abuse, but advances in machine learning have reduced the effectiveness of traditional challenge-based designs and exposed limitations in proprietary risk-scoring systems. This paper presents an adaptive, reinforcement learning-based CAPTCHA defense framework for high-security web applications. The proposed system formulates bot detection as a partially observable Markov decision process and uses a Proximal Policy Optimization (PPO) agent with Long Short-Term Memory to analyze streamed behavioral telemetry, including mouse movements, clicks, keystrokes, and scrolling, over sequential interaction windows. During the observation phase, …
Choline Counteracts Pregnancy Undernutrition-Associated Colitis In Sheep By Restoring Microbiota Driven Bile Acid Metabolism, Weibin Wu, Peng Jiao, Yamei Gu, Huizhen Lu, Caiyun Fan, Zheng Sun, Lizhuang Hao, Shengyong Mao, Jianbo Cheng, Yanfeng Xue
Choline Counteracts Pregnancy Undernutrition-Associated Colitis In Sheep By Restoring Microbiota Driven Bile Acid Metabolism, Weibin Wu, Peng Jiao, Yamei Gu, Huizhen Lu, Caiyun Fan, Zheng Sun, Lizhuang Hao, Shengyong Mao, Jianbo Cheng, Yanfeng Xue
Faculty, Staff and Students Publications
High-fertility sheep experience undernutrition during late gestation, which induces body metabolic disruption and intestinal inflammation. Crucially, the gut microbiota-bile acid axis is a promising intestinal inflammation target, but how choline modulates this axis in livestock enteritis is unknown. This study investigated choline's protective mechanisms against undernutrition-induced intestinal inflammation in sheep, focusing on gut microbiota and bile acid regulation. Choline consistently alleviates colitis severity, restores epithelial barrier integrity, and suppresses intestinal inflammation. These protective effects are accompanied by pronounced remodeling of the colonic microbial ecosystem, characterized by the enrichment of Clostridiales bacterium to elevate bile salt hydrolase activity and regulate bile …

Posts, Not Personae: Why Influencer Personae Fall Outside The Doctrine Of Character Copyright, Abbey Brantley
Journal of Intellectual Property Law
Over the past decade, social media has enabled an increasing number of people to pursue influencing as a full-time career on platforms such as TikTok, Instagram, and YouTube. To succeed commercially, these creators make repeated stylistic choices that both conform to online trends and project a carefully curated persona. As these personae become profitable, however, they also become susceptible to imitation. This dynamic raises the question whether copyright law, specifically the doctrine of character copyright, can protect influencers from unauthorized copying of their online identities. This Note argues that influencer personae do not and should not qualify for such protection, …
Patents And Technology Evolution: Altering Innovations And Innovators Via Patent Influences, Richard Gruner
Patents And Technology Evolution: Altering Innovations And Innovators Via Patent Influences, Richard Gruner
Journal of Intellectual Property Law
Technologies improve primarily through evolutionary change not rational optimization. New technologies emerge as attempts to solve practical problems, the technologies are tested in marketplaces to determine if they are superior in cost and function to alternatives, and those that fare well in the testing gain widespread adoption. Widely adopted technologies, and their problems, form the basis for the next round of technology improvements and evolution. Through these steps, evolutionary processes lacking rational direction can generate changing technologies matched to the desires and problems of present society.
As they operate to advance diverse technologies, evolutionary processes governing technology change are subject …
The Prestige Economy Of Legal Scholarship, Jeffrey A. Katz, Jacob Sandler
The Prestige Economy Of Legal Scholarship, Jeffrey A. Katz, Jacob Sandler
Florida Law Review
Law reviews sit at the center of American legal scholarship, but their role is widely misunderstood. They are not peer-reviewed, yet the academy treats their placement decisions as markers of scholarly merit. This Essay argues that law reviews function as participants in a prestige economy—one in which reputation, familiarity, and institutional brand often matter more than substantive judgment. Tracing the student-edited model from its pedagogical origins to its modern professional consequences, this Essay shows how prestige became currency, how that currency shapes editorial and authorial behavior, and why the system strains under political and methodological pressure. It concludes by urging …
Fate Of Nitrogen Applied To Grassland In Animal Wastes, M Sherwood
Fate Of Nitrogen Applied To Grassland In Animal Wastes, M Sherwood
IGC Proceedings (1977-2023)
The experiment was designed to determine the effects of land spreading of animal manures on the nutrient content of surface runoff water and infiltrating soil water. This report deals only with nitrogen (N) and attempts to quantify the losses through runoff, leaching, and volatilization of ammonia (NH3) as well as N uptake in the grass over a 3-year period. Experimental plots sited on grassland, on two soil types (a moderately drained loam and an impermeable gley), were equipped to collect surface runoff water. Ceramic probes were installed in each plot at 15-, 30-, 60-, and 100-cm depths to extract infiltrating …
Nitrogen Losses From Urine-Affected Areas Of A New Zealand Pasture, Under Contrasting Seasonal Conditions, P R. Ball, D R. Keeney
Nitrogen Losses From Urine-Affected Areas Of A New Zealand Pasture, Under Contrasting Seasonal Conditions, P R. Ball, D R. Keeney
IGC Proceedings (1977-2023)
Grazing ruminants aggregate large quantities of forage nitrogen (N) into urine patches. Pasture plots treated with urine N were studied to assess its fate under contrasting seasonal conditions: cool-moist (representing winter-spring); warm-moist (late spring-early summer), and warm-dry (late summer-autumn). A permanent ryegrass (Lolium perenne L.)-white clover (Trifolium repens L.) sward on free-draining alluvial soil was studied. 'freatments were replicated in randomized blocks. Urine N was applied at 30 or 60 g N/m2• Relevant measurements were then continued until treatment differences disappeared. Apparent N balances for urine treatments were compiled. Fixation by white clover was always greatly reduced in …
Effects Of Water Stress On Herbage Quality, J R. Wilson
Effects Of Water Stress On Herbage Quality, J R. Wilson
IGC Proceedings (1977-2023)
Uncertainty exists about whether drought is detrimental to the nutritive quality of herbage. This paper tries to resolve this uncertainty by examining the influence of soil moisture on some herbage-quality characteristics. Unpublished data from my own work and review of published literature are presented. Field plots of three tropical grasses, green panic (Panicum maximum var. trichoglume), buffelgrass (Cenchrus ciliaris), and speargrass (Heteropogon contortus), were subjected to perioqs of controlled drought, and herbage from these plots was compared with that from well-watered plots. Leaf and stem dry-matter ?igestibility of water-stressed herbage was either similar to or higher than that of unstressed …
