Working Paper No. 102, Knowledge And Power: Towards Anintellectual Biography Of Michel Foucault, Amanda Bergeson Jun 2025

Working Paper No. 102, Knowledge And Power: Towards Anintellectual Biography Of Michel Foucault, Amanda Bergeson

Working Papers in Economics

This inquiry seeks to establish that in his efforts as an intellectual, scholar, and author of books that would include Discipline and Punish [1975], Michel Foucault emphasizes the importance of power and power relations, especially of an authority (such as a sovereign) over the common people. Drawing from Discipline and Punish [1975], this inquiry considers how Foucault’s understanding of genealogy got rooted and shaped by Friedrich Nietzsche’s critique of history; a view which altogether challenged the idea of historical progress, while also revealing the contingent nature of truth. The second section considers how sovereign power evolves into disciplinary mechanisms embedded …


Working Paper No. 103, Russia And The Myriad Of Challenges Associatedwith ‘Relative Backwardness’, Jacob Wood Jun 2025

Working Paper No. 103, Russia And The Myriad Of Challenges Associatedwith ‘Relative Backwardness’, Jacob Wood

Working Papers in Economics

This inquiry seeks to establish that over recent of centuries Russia exhibits signs of what is termed as ‘relative backwardness.’ Drawing from Alexander Gershenkron’s (1962, 62-70) understanding of ‘backwardness in historical perspective,’ as well as Karl Marx’s ([1845] 1977, 39-43) concept of ‘historical materialism,’ this inquiry examines how successive Russian regimes sought to close the developmental gap with western countries through state-led modernization efforts. What stands out is that when confronted with attempting deep structural challenges, each leader turned to centralized authority and coercive reforms—not by choice, but out of necessity. Our inquiry considers Nicolas II’s failure to modernize Russia’s …


Hydrogen Storage In Multilayer Ti3c2tx Mxene, Yi Zhi Chu, Kah Chun Lau Jun 2025

Hydrogen Storage In Multilayer Ti3c2tx Mxene, Yi Zhi Chu, Kah Chun Lau

Michigan Tech Publications

In this work, we systematically investigated the hydrogen storage properties of multilayer Ti3C2Tx MXene using density functional theory (DFT) coupled with the quantum-thermodynamic model to include the thermodynamic effect on hydrogen adsorption and storage behavior over a wide range of applied pressure and temperature. In addition to the surface-adsorbed hydrogen, we show that the interlayer spacing is a plausible storage route that could contribute to an additional hydrogen storage capacity. Due to hydrogen-bond bounded multilayer Ti3C2Tx, the insertion, diffusion, and adsorption of hydrogen molecules into the interlayer spacing of the multilayer structure require sufficient external pressure to overcome the energy …

Type I Interferon Protects Against Bone Loss In Periodontitis By Mitigating An Interleukin (Il)-17-Neutrophil Axis, Jinmei Zhang, Qiong Ding, Angela X Wang, Maoxuan Lin, Ning Yu, Kevin Moss, Megumi A Williamson, Di Miao, Julie T Marchesan, Erliang Zeng, Wei Shi, Hongli Sun, Yu Leo Lei, Shaoping Zhang

Faculty, Staff and Student Publications

Type I interferons (IFNs-I), a group of pleiotropic cytokines, critically modulate host response in various inflammatory diseases. However, the role of the IFN-I pathway in periodontitis remains largely unknown. In this report, we describe that the IFN-β levels in the gingival crevicular fluid of human subjects were negatively associated with periodontitis and clinical gingival inflammation. Disruption of IFN-I signaling worsened alveolar bone resorption in a ligature-induced periodontitis murine model. Deficiency of the IFN-I pathway resulted in an exaggerated inflammatory response in myeloid cells and drastically increased the interleukin-17 (IL-17)-mediated neutrophil recruitment in the gingiva. We further identified that the myeloid …

Elite Cohesion And Its Historical Sources: Analyzing Its Impact On Democratization In Nigeria And Botswana, Aliaa Magdy Aboutera Jun 2025

Elite Cohesion And Its Historical Sources: Analyzing Its Impact On Democratization In Nigeria And Botswana, Aliaa Magdy Aboutera

Theses and Dissertations

This thesis examines the divergent democratization trajectories of Botswana and Nigeria, focusing on the role of colonial legacies and post-colonial elites in shaping elite cohesion. While both countries experienced British colonial rule, their transitions to democracy in the post-independence period have differed significantly. This study argues that elite cohesion, although insufficient on its own, is a critical facilitating factor in democratic consolidation that warrants greater attention in the democratization literature. This cohesion is largely shaped by the sociology of political elites, with historical contexts influencing how elites organize. Through process tracing, the thesis argues that colonialism in Botswana did not …

So Who Gets To Be Modern? Jadidism And Reform In Late Nineteenth And Early Twentieth Century Russia, Grant Douglas Linville Jun 2025

So Who Gets To Be Modern? Jadidism And Reform In Late Nineteenth And Early Twentieth Century Russia, Grant Douglas Linville

University Honors Theses

Jadidism was a sociocultural reformist project from the 1880s to 1920s developed by Muslim intellectuals in the Russian Empire and the Soviet Union. The Jadidist movement derives its name from the "new-method" (usul-al Jadid) schools that spread Jadid pedagogy, which revolved around the inclusion of secular topics and Western knowledge as well as instruction in local, Tatar, and Russian languages, in addition to the already present religious studies accompanied by Arabic and Persian taught in the Islamic educational institutions the maktab and madrasa (primary and higher education respectively). Over time Jadidism grew to encompass a host of societal …

It investigates how manga functions not only as a storytelling medium but as a sociocultural mirror, uniquely positioned to illuminate the often-invisible negotiations of identity, shame, and social position that queer individuals experience in Japan. Through the lens of Takie Lebra's concept of bun (role or place in society), this project explores the ways in which queer characters seek legitimacy, …


Is Anoxia Tolerance A Common Trait In Fish Cell Lines?, Lori Tran Jun 2025

Is Anoxia Tolerance A Common Trait In Fish Cell Lines?, Lori Tran

University Honors Theses

Most vertebrates need a constant supply of oxygen to sustain life, with disruption to O2 supply or delivery quickly leading to cell and tissue damage and death. Many aquatic species are able to withstand long periods without O2 due to evolving to survive the regular periods of hypoxia and anoxia in their natural habitat. The Austrofundulus limnaeus, or the annual killifish, in particular have shown the highest anoxia tolerance in all vertebrates and is a promising model for developing effective treatments for anoxia-related damage, such as heart attacks and strokes. The A. limnaeus are not the only …


Beyond Capitalist Realism: Indigenous Worldviews As Critique And Alternative, Celine Jessup Jun 2025

Beyond Capitalist Realism: Indigenous Worldviews As Critique And Alternative, Celine Jessup

University Honors Theses

This paper engages Mark Fisher's Capitalist Realism: Is There No Alternative? as a foundational critique of late capitalism's ideological dominance, and proposes Indigenous worldviews as both a critical lens and a generative alternative. Fisher defines capitalist realism as a pervasive structure that colonizes imagination, depoliticizes systemic crises, and renders other ways of living unthinkable. He illustrates how capitalism commodifies resistance, pathologizes dissent, and obscures accountability, particularly through institutions like the call center and discourses on mental health and climate change. In contrast, the paper turns to Indigenous political theories—drawing on thinkers such as Kim TallBear, Daniel Heath Justice, Ocean Ripeka …

Testing Their Limits: Impact And Intentions Of Standardized Testing In K-12 Schools, Grace O. Herd Jun 2025

Testing Their Limits: Impact And Intentions Of Standardized Testing In K-12 Schools, Grace O. Herd

University Honors Theses

The integration of High-Stakes standardized testing into U.S. public education to serve as an accountability system has been a disputed issue since the No Child Left Behind Act (NCLB) mandated these assessments nationwide in 2002. NCLB aimed to locate and identify schools failing to reach Adequate Yearly Progress (AYP) and trigger a chain of interventions based on student performance, as an effort to track measurable outcomes from federal education funding. While supporters view these standardized tests as quantifiable data for school effectiveness in academics, critics challenge the claim of validity.

This review integrates current psychological research in the area of …


At Home In Horror: Women And Body Horror, Brooklynn Kreps Jun 2025

At Home In Horror: Women And Body Horror, Brooklynn Kreps

University Honors Theses

While most discussion around the subgenre of body horror focuses on its birthplace of film, the richest iterations come from women writing body horror fiction to explain the experience of womanhood. As body horror focuses on fear of painful or absurd mishap with the body. Women experience pain or absurdity in their own bodies every day with processes like menstruation, pregnancy, puberty, and heightened chances of becoming a victim of sexual assault. Furthermore, women experience society's forceful shaming and fear about natural processes of the body and experiences such as anger and sexual desire. Using this idea as a framework, …

Metabolic-associated fatty liver disease (MAFLD) represents an increasing global health challenge, with cholesterol-associated steatohepatitis (CASH) emerging as a distinct pathological entity warranting investigation. While CASH demonstrates unique features compared to traditional triglyceride-driven steatohepatitis, its underlying molecular mechanisms remain poorly understood. This study investigates a novel regulatory axis involving DPPA2 Upstream Binding RNA (DUBR), miR-210-5p, and retinol saturase (RETSAT). 170 patient samples revealed progressive axis dysregulation in disease states, with RETSAT emerging as a highly accurate diagnostic marker (AUC=1.000). Using novel in vitro models of MASH and CASH, we demonstrated that miR-210-5p modulation significantly affects lipid accumulation and cellular phenotype, with …


Characteristics, Behaviour And Fluxes Of Microplastics In The Coastal Boundary Zones Of The Persian Gulf And Oman Sea, Sajjad Abbasi, Andrew Turner Jun 2025

Characteristics, Behaviour And Fluxes Of Microplastics In The Coastal Boundary Zones Of The Persian Gulf And Oman Sea, Sajjad Abbasi, Andrew Turner

School of Geography, Earth and Environmental Sciences

Relatively little is known about microplastics (MPs) in the atmosphere of the coastal zone, including their interaction with the sea surface. In this study, MPs have been determined and characterised in the lower atmosphere, advecting air, depositing dusts, coastal sediments and seawater of the Persian Gulf and Oman Sea using a variety of sampling techniques (including filtration of water and pumped air and deployment of a vertical array of sediment traps). MPs were detected in all samples and were dominated by fibres that were, in most cases, small (<100 μm) and black. MP numbers captured in advecting air showed no trends with height or differences between locations or deployments over land and sea, but a clear increase was observed during strong winds. MPs in atmospheric suspension and in deposited dusts, sediments and seawater were also heterogeneously distributed. Environmental or transport pathway fractionation was evident according to morphology and particle size (% fibres and % small fibres) and to polymer density. Regarding the latter, relatively low-density polymers (e.g., polyethylene, polypropylene) were more abundant in the atmosphere, advecting air and seawater, whereas higher density polymers (e.g., regenerated cellulosics, polyethylene terephthalate) were more abundant in settling dusts and sediments. Fluxes, based on particle counts and converted MP m−2 h−1, revealed advection (up to ∼ 1.2 × …
