Working Paper No. 97, Business Sabotage In Theory And Practice, Nathan Lewis-Lusso Jun 2025

Working Paper No. 97, Business Sabotage In Theory And Practice, Nathan Lewis-Lusso

Working Papers in Economics

This inquiry seeks to establish that theoretical advances offered earlier on by one Karl Marx and some decades later by one Thorstein Veblen offer insights into forms of business sabotage. Drawing upon their writings, this inquiry considers how in the writings of Marx, already in the mid-nineteenth century surplus value extraction and pecuniary sabotage serve as structural features found in a market-based economy. Marx’s consideration of surplus labor and artificial scarcity reveals how private investment seeks to constrain production in order to preserve and enhance profitability. Veblen’s theory of institutional sabotage complements Marx’s view by showing how firms could delay …

Intersectional Realities, Multi-Dimensional Films: Reading Julie Dash's Illusions As An Activist Text, Amelia Morrison Jun 2025

Intersectional Realities, Multi-Dimensional Films: Reading Julie Dash's Illusions As An Activist Text, Amelia Morrison

University Honors Theses

This paper reads Julie Dash's 1982 film Illusions as an activist text, which challenges dominant cinematic and historical narratives through its Black feminist perspective. It explores the cinematic and narrative devices that Dash uses--including the weaving of fantasy and history, the strategic use of period aesthetics, and masking--to expose and subvert the mechanisms of white supremacist and patriarchal hegemony within Hollywood. Drawing on intersectional feminist theory from scholars like Kimberlé Crenshaw, Patricia Hill Collins, and bell hooks, alongside cinematic theory, this analysis demonstrates how Illusions critiques the historical erasure of people of color from United States cinema and history. By …


Freeing The Fremont: Visions Of A Post-Automobile Portland Highway Bridge, Henry Senters Jun 2025

Freeing The Fremont: Visions Of A Post-Automobile Portland Highway Bridge, Henry Senters

University Honors Theses

The Fremont Bridge is an iconic piece of highway transportation infrastructure in the city of Portland, Oregon. Unfortunately, it is one of only three Willamette bridges in the city that does not allow any pedestrian access, except for a single day every year during an annual bicycling event. Consider, however: what if that were to change, in a future less dependent on private automobile usage? Drawing on historical precedents of pedestrian and car-free bridges, this thesis proposes three types of pedestrian-focused programs which a car-free Fremont Bridge could host, each of which speaks to a current aspect of civic life …

This narrative review examines organization and systems literature to provide recommendations for …


Identifying The Drivers Behind The Decline Of Douglas-Fir And True Fir Species In Sw Oregon, Alexander Bryant Bentley Jun 2025

Identifying The Drivers Behind The Decline Of Douglas-Fir And True Fir Species In Sw Oregon, Alexander Bryant Bentley

Dissertations and Theses

Increased levels of Pseudotsuga menziesii (DF) and Abies species (TF) decline throughout dry forests in the Klamath Mountains and Western Cascades ecoregions have been recorded in recent years, with preliminary evidence suggesting that factors influenced by changing climatic conditions and encroachment from fire suppression policies are primarily to blame. Yet, the physiological and environmental mechanisms of drought-driven tree decline are poorly understood across biophysical and spatial gradients. Given the complex relations that drive decline, determining the degree of influence of specific drivers is difficult, creating unique challenges for modern forest management. To elucidate the most important factors driving DF and …

Codifying Capital: Legal Power, Racial Hierarchy, And The Gendered Dynamics Of Law, Tavia Andrew Jun 2025

Codifying Capital: Legal Power, Racial Hierarchy, And The Gendered Dynamics Of Law, Tavia Andrew

University Honors Theses

This paper analyzes how law operates as a structuring force within racial capitalism by applying Austin Turk's "law as power" framework. It explores how legal institutions not only reflect but actively reproduce racial and gender hierarchies through their functions. Drawing from foundational work by Cedric Robinson, W.E.B. Du Bois, Angela Harris, Kimberlé Crenshaw, and others, this paper defines racial capitalism as a system in which economic exploitation is inseparable from racial and gender domination. The first section contextualizes the emergence of racial capitalism and its intersection with gender, emphasizing how bodies are commodified and governed through legal regimes. The core …


From Prohibition To Prescription: Exploring Injustice, Bias, And Science-Based Solutions, Alexander Campos Jun 2025

From Prohibition To Prescription: Exploring Injustice, Bias, And Science-Based Solutions, Alexander Campos

University Honors Theses

This thesis critiques the war on drugs for disproportionately targeting minority communities and prioritizing systemic exploitation over public health. It examines the flawed, politically influenced DEA drug scheduling process, which neglects evidence of the medical benefits of substances like cannabis, psilocybin, LSD, DMT, and MDMA. This thesis gives a brief history of the evolution of US drug policy, which contributed to mass incarceration, reinforced racial disparities, and failed to reduce overdose deaths. It also highlights the potential mental health benefits of decriminalizing and regulating psychedelics to treat conditions like PTSD, depression, and substance abuse disorder. This thesis concludes by promoting …

Development Of A Low-Cost Electron Microscope For Educational Purposes, Christopher Halseth Jun 2025

Development Of A Low-Cost Electron Microscope For Educational Purposes, Christopher Halseth

Dissertations and Theses

Electron microscopy is a powerful tool for exploring microscopic world, yet its high cost and operational complexity severely limit accessibility, particularly within educational institutions. Commercial systems are often designed as opaque "black boxes," further hindering hands-on learning and experimentation. This dissertation introduces the Educational Scanning/Transmission Electron Microscope (EduSEM), a project designed to overcome these barriers by developing a low-cost, modular, and transparent electron microscope optimized for educational use.

The EduSEM achieves significant cost reduction by operating in a rough vacuum environment (1-20 mTorr), eliminating the need for expensive high-vacuum pumps. This necessitates novel component designs tolerant of higher pressures. The …


Range-Dependent Meso-Scale Geoacoustic Seabed Quantification, Tim Sonnemann, Jan Dettmer, Charles W. Holland, Stan E. Dosso Jun 2025

Range-Dependent Meso-Scale Geoacoustic Seabed Quantification, Tim Sonnemann, Jan Dettmer, Charles W. Holland, Stan E. Dosso

Electrical and Computer Engineering Faculty Publications and Presentations

This study presents a probabilistic one-step two-dimensional (2D) inversion method of spherical-wave reflection coefficient data to estimate the range-dependent structure and geoacoustic parameters along a track. The approach of inverting such datasets independently as one-dimensional (1D) layered models and merging them to a 2D section is feasible but computationally expensive. This study demonstrates a more parsimonious 2D parametrization for active source data recorded on a towed hydrophone array. The comparison of data variance reduction for 1D- and 2D-based results clearly favors the 2D parametrization described here.

To meet this demand, the 3rd Generation Partnership Project (3GPP) is promoting the integration of 5th Generation Mobile Communication Technology (5G) and Time-Sensitive Networking (TSN). Time synchronization is essential for deterministic data transmission. Based on the 3GPP’s vision of the 5G and TSN integrated networking with interoperability, we improve the time synchronization of TSN to conquer the multi-gNB competition, re-transmission, and mobility problems for the integrated 5G time synchronization. We implemented the improvement mechanisms and systematically validated the …


Distributed Energy Resources: A Systematic Literature Review, Midrar Adham, Sean Keene, Robert B. Bass Jun 2025

Distributed Energy Resources: A Systematic Literature Review, Midrar Adham, Sean Keene, Robert B. Bass

Electrical and Computer Engineering Faculty Publications and Presentations

The traditional power grid, characterized by its centralized nature and one-way power flow, has long been the backbone of electricity supply and distribution. Grid operators have historically found various ways to accurately predict demand, anticipate faults, and prepare appropri- ate responses. However, with the rapid integration of Distributed Energy Resources such as Photovoltaic, storage systems, grid-interactive generation, and flexible-load assets, energy consumption and production patterns have become less predictable, transforming the grid into a two-way power flow system. Managing the potential of these Distributed Energy Resources requires advanced management systems that provide monitoring, coordination, and aggregation capabilities to …

Geography Faculty Publications and Presentations

We synthesized more than 70 articles, most peer reviewed, that addressed the heat wave that occurred across the Pacific Northwest of the United States and Canada in late June 2021, breaking hundreds of daily and all-time daily maximum temperature records across the region. A persistent, extraordinarily strong ridge of high pressure was a primary driver of the heat wave. Contributing mechanisms were moisture originating in the tropical western Pacific Ocean, high solar radiation, low pressure offshore, large-scale subsidence over land, and unusually dry soils. Climate change contributed to the heat wave’s magnitude by increasing mean temperature, although it is unclear …

Soil carbon dioxide (CO2) flux, or soil respiration, is a critical control on net ecosystem carbon (C) balance. Using long-term (2002-2020) measurements at the Hubbard Brook Experimental Forest (New Hampshire, U.S.), we show that soil respiration rates have notably increased since ~2015. In 2020, cumulative summer respiration flux was approximately 90% higher than the average summer flux over the 2002–2015 period. The increase in soil respiration cannot be explained directly by temperature or pH change alone. We also found that heterotrophic microbial C mineralization and microbial biomass C have also increased rapidly since ~2015, pointing towards an increase in the …
