Working Paper No. 86, The Evolution Of Japan's Economy, Kasandra Reyes Fernandez

Working Papers in Economics

This inquiry seeks to establish that already from its feudal era characterized by fiefdoms and kingdoms to its development as a modern nation- state, Japan’s economic history reveals discernible variants of capitalism. Highlighting these variants assist us in defining distinct eras that also offer the observer a sense of the evolution of Japan’s economy. In advancing this thesis, the first part considers differences between variants of capitalism found in the Tokugawa Era and, after 1868, what is designated as the Meiji Era. The focus shall be on the economic foundations of the Tokugawa shogunate versus the nascent industrialization during the …

Working Paper No. 92, Karl Polanyi, Human Labor, And The Working Class, Niccolo Cellini

Working Papers in Economics

This inquiry seeks to establish that Karl Polanyi advanced ideas regarding human labor that we could judge as both seminal and enduring. Through examining his famous book, The Great Transformation, we could draw out three interconnected theses central to his critique of market-oriented economies. Firstly, we could emphasize that Polanyi judges labor as a fictitious commodity, emphasizing distinct aspects associable with labor’s emergence during the industrialization of England. In developing his ideas Polanyi draws upon the historical examples of the Speenhamland System and Frederick Engels' accounts of industrial labor that highlighted the destabilizing effects of embedding labor within …

Farmers’ Decision Processes About Biocontrol Innovation Adoption: Dynamics Surrounding Push-Pull Technology In Western Kenya, Olufemi Samson Adesina, Stephen Whitfield, Susannah M. Sallu, Steven M. Sait, Jimmy Pittchar

All Peer-Reviewed Publications

Smallholder farmers in sub-Saharan Africa (SSA) face increasing challenges from pests and climate change, among other issues. In response to these challenges, international agricultural research for development (R4D) investment is often focused on developing and scaling up techniques and technologies that bolster resilience. However, such approaches are often technocentric and follow linear assumptions of innovation diffusion and adoption, which overlook the complex realities that influence smallholder farmers’ dynamic decisions and engagement with novel techniques. This study used qualitative ethnographic methods to explore the experiences, knowledge construction, motivations, and decision-making of farmers in Western Kenya regarding the extensively researched push-pull technology …

Greening Of A Boreal Rich Fen Driven By Co2 Fertilisation, Sandeep Thayamkottu, T. Luke Smallman, Jaan Pärn, Ülo Mander, Eugénie S. Euskirchen, Evan Kane

Michigan Tech Publications

Boreal peatlands store vast amounts of soil organic carbon (C) owing to the imbalance between productivity and decay rates. In the recent decades, this carbon stock has been exposed to a warming climate. During the past decade alone, the Arctic has warmed by ∼ 0.75°C which is almost twice the rate of the global average. Although, a wide range of studies have assessed peatlands’ C cycling, our understanding of the factors governing source / sink dynamics of peatland C stock under a warming climate remains a critical uncertainty at site, regional, and global scales. Here our focus was on answering …

3d Game: Enhancing Game Ai With Machine Learning, Nicholas William English

Masters Projects

Machine learning (ML) and artificial intelligence (AI) are terms that are often used synonymously, but they are ever-so slightly different. Machine learning is really a subset of artificial intelligence and involves creating an algorithm so that a computer can learn patterns. Artificial intelligence extends machine learning with the goal to go beyond pattern recognition by having a computer that is capable of mimicking human intelligence. Video games often use the term AI in reference to the bots or non-playable characters (NPCs) that players may interact with. Generally, these bots do not actually implement AI, nor do they use ML, but …

Simulation Studies Of Mvdc Power Cable For All Electric Aircrafts, Aban Samimi Motlagh

Electrical and Computer Engineering ETDs

MVCD power cable has a vital task in future commercial electric aircraft, which is power delivery. The temperature of the cable during the cable’s operation under low pressure is higher than the atmospheric pressure, which increases the cable losses. In this paper, the temperature and electric field across the insulator of the 5 kV DC Southwire cable is simulated up to 10 hours of cable operation. Furthermore, the temperature of the cable is shown with and without the presence of the chamber box. The other issue of the MVDC power cable is the cable joints and terminations. The electric field …

Theory And Algorithms To Learn, Propagate, And Exploit Uncertainty For Stochastic Optimal Control Of Dynamical Systems, Vignesh Sivaramakrishnan

Electrical and Computer Engineering ETDs

Non-Gaussian uncertainty frequently arises in learning and control problems involving stochastic dynamical systems, particularly in autonomous vehicles, UAVs, satellites, and robotics. In this dissertation, we propose a new framework that leverages characteristic functions that provides a frequency-domain representation of random variables. The dissertation is structured into three key areas. First, we address model-based stochastic optimal control for linear systems with non-Gaussian noise, demonstrating that characteristic functions can be used to enforce chance constraints and control systems toward desired distributions. Second, we explore data-driven stochastic control, utilizing empirical characteristic functions to handle systems with unknown disturbances. In addition, we derive several …

Targeting Myeloid Cell Iron Metabolism In Salmonella-Induced Colitis, Mariella Arcos Padilla

Biomedical Engineering ETDs

Salmonellosis is a severe infection caused by Salmonella enterica serovar Typhimurium, leading to significant global morbidity and mortality.

Previous studies have shown that mice lacking the iron storage protein ferritin heavy chain (FTH1) in myeloid cells exhibit worsened Salmonella infection. Nuclear receptor co-activator 4 (NCOA4) directs FTH1 autophagic degradation to release iron from storage during conditions of low iron. However, the role of myeloid NCOA4 in regulating bacterial infections remains unclear.

Here, we found that myeloid NCOA4 deficiency augments spleen iron levels and increases cellular iron accumulation, oxidative stress, and ferroptosis in bone marrow-derived macrophages (BMDM) cells. This deficiency also …

Modern Agricultural Servitude: The Modern Farm Worker Experience In The Salinas Valley, Jesus E. Tavarez

Chicana and Chicano Studies ETDs

The prevailing narrative in Chicanx studies focuses on the historical labor activism of the United Farm Workers (UFW) in the 1960s and ‘70s. I am particularly interested in examining the contemporary campesino experience in the Salinas Valley by discussing the history behind Mexican cheap labor, low wages, exploitive work conditions with inadequate healthcare, agrochemical exposure, and historical consciousness of farm workers. I will argue that farm workers are in dire need of a migratory reform as an approach to improve the working conditions of farm workers throughout California. This research aims to shed light on how the multi-billion-dollar agribusiness industry …

Forest Response To Increasingly Frequent Fire And Drought Disturbances, Kevin G. Willson

Biology ETDs

Changes in fire regimes and drought intensity have increased fire and drought severity in southwestern forests, decreasing forest resilience to recent changes in climate. As tree response and regeneration after disturbance are critical for forest persistence, this dissertation assesses ponderosa pine regeneration patterns after high-severity fire, tree growth response to the reintroduction of frequent-fire, and tree growth response to multiyear droughts in fire-maintained and fire-excluded forests. We found that high-severity patch locations were more likely to regenerate when positioned downwind, downslope, and near intact forest. Trees had similar growth responses to first-entry fires and reburns following long-term fire-exclusion. After experiencing …

Tnf Prevents Establishment Of Anti-Tumor Immunity And Elucidates Toxicities Following Myxoma Virus Based Oncolytic Virotherapy, Miriam Beatriz Valenzuela Cardenas

Biomedical Sciences ETDs

Tumor Necrosis Factor Alpha (TNF) can lead to tumor regression through its direct cytolytic activity, yet it has also been implicated to facilitate tumor progression. This scenario complicates the efficacy and applicability of TNF based therapeutics as treatment for malignancies. In the context of oncolytic virotherapy (OV) which uses replicating viruses to treat tumors and acts by triggering production of pro-inflammatory cytokines, exploring such mechanisms is vital. Here we show that a Myxoma based oncolytic virus (vPD1/IL12) can induce large amounts TNF. The presence of TNF in the context of vPD1/IL12 plays a detrimental role both for tumor regression by …

Evaluation Of Electrode Configurations For (0,2) Piezoelectric Ultrasound Transducers, Abdul Qayoum Popal

Mechanical Engineering ETDs

Piezoelectric micro ultrasound transducers (PMUT array) are pivotal in MEMS applications. They typically operate in the fundamental (0,1) acoustic mode and are not significantly researched for higher modes (0,2) and (0,3). Similarly, vibrating mesh atomizers (VMAs) demand the second (0,2) mode and third mode (0,3) for effective aerosol generation, highlighting the need for optimized electrode configurations—a relatively unexplored area. This study presents the first comprehensive analysis of how electrode designs influence PMUT performance in the (0,2) mode for VMA applications.

Utilizing COMSOL multiphysics finite element modeling (FEM) with residual stress considerations alongside experimental validation, we demonstrate that optimized electrode configurations …

Operations On Submodules With The Multiplicative And Quotient Properties, Jiekai Pang

Mathematics & Statistics ETDs

Inspired by the works of Petro, Epstein, Vassilev, and Morre, this thesis aims to study the generalized definitions of the semiprime operation, weakly prime operation, and standard closure operation on rings, that is, the multiplicative operation, weakly multiplicative operation, and standardly multiplicative operation on submodules. Then, we will use Matlis duality to induce the dual notions of these definitions on submodules of Matlis-dualizable Artinian modules. In order to understand the dual notion of the standardly multiplicative operation, that is, the standardly quotient operation, we will classify the operations on the injective hull of residue field of the ring K[[x,y]]/(xy) which …

Conceptualization, Measurement, And Contributors To Participation Among People Living With Parkinson’S Disease, Moon Young Kim

WUSM Theses and Dissertations – All Programs

Participation is a key outcome of rehabilitation and key to successful aging. Individuals with Parkinson’s disease (PD) often experience significant challenges in maintaining participation in meaningful activities and roles. This dissertation examines the influence of living with PD on participation by integrating findings from three studies: a systematic review, a cross-sectional study, and a longitudinal study.

The systematic review synthesized the existing quantitative research on participation in people with PD, revealing inconsistencies in the conceptualization of participation. While the evaluation tools aimed at assessing participation in PD showed acceptable coverage of domains of participation, the assessment of the aspects of …

Triangulating The Likelihood Of Confusion: Linguistics And Consumer Surveys, Eric Derosia, Jesse Egbert, Thomas Lee

BYU Law Review

This Article highlights contributions that linguistic analysis can offer in the assessment of the likelihood of confusion in trademark infringement cases. Parties in such cases often engage an expert witness to conduct a survey that measures the likelihood of consumer confusion. We show how an expert linguist can provide important, nonintuitive dynamics of corroboration. We introduce “expert triangulation” as a conceptual framework to analyze whether, and to what extent, experts in linguistics and consumer surveys can corroborate one another. That is, having two different sources of empirical evidence which lead to similar conclusions should be a benefit to the courts, …

Going Generic: A Linguistics Approach To Genericide In Trademark Law, James A. Heilpern, William G. Eggington, Earl Kjar Brown, Zachary D. Smith

BYU Law Review

This Article examines the phenomenon of trademark genericide—the process by which once-protected brand names like “escalator” and “trampoline” lose their legal status by becoming synonymous with entire product categories. Traditional methods used by courts to assess genericide, such as consumer surveys and dictionary definitions, are often criticized for their subjectivity and lack of scientific rigor. In response, this Article introduces corpus linguistics as a more reliable, data-driven alternative for determining whether a trademark has become generic.

By analyzing real-world language usage through large corpora, corpus linguistics can track the public’s shifting perceptions of a trademark over time. Using case studies …

Disclose By Law, Obfuscate By Strategy: A Corpus-Based Analysis Of Patent Filings, Katherine Ireland, W. Michael Schuster, Tim R. Samples

BYU Law Review

The patent system encourages dissemination of technical information by granting inventors exclusive rights to their inventions in exchange for public disclosure of their technology. The American Inventors Protection Act (AIPA), enacted in 1999, advanced this goal by increasing the scope and speed of disclosure. Previously, filings were published only if and when a patent was granted, but under the AIPA most applications are published eighteen months after filing. The sum of those changes amplified a fundamental tradeoff between protection and exposure. Although patents offer protection, competitors can exploit disclosures by integrating the innovations into their own research and development efforts. …

Corpus Linguistics And The Original Meaning Of The Sixth Amendment, Wesley White

BYU Law Review

The Sixth Amendment guarantees the right of an accused to have the assistance of counsel in a criminal prosecution. Put simply, under the U.S. Supreme Court’s current framework, an accused does not enjoy this right until the government has brought a formal charge. Thus, an accused who engages in plea bargaining before being formally charged is not guaranteed the Sixth Amendment right to counsel. Many critics of this framework focus on the purpose of the Sixth Amendment to argue that the right to counsel should be guaranteed in pre-charge plea bargaining. Others point to policy concerns.

This Note is among …
