Anamnesis, Kristian Thacker

Graduate Theses, Dissertations, and Problem Reports (ETD)

My work examines the duality of living in Appalachia and cherishing its picturesque environment; while being complicit in its ongoing destruction via industry and resource extraction. Composed of my own photographs and selections from the Farm Security Administration archives, this body of work presents a vision of the region that’s purpose extends beyond value judgments. Rather, it considers the manmade and natural environments of Appalachia holistically, each one integral to the experience and understanding of the other. Following the same aesthetic choices I make in my professional practice as a photojournalist, I blur the boundary between art and documentation. In …

Three Essays In Urban And Regional Economics, Bryan Khoo Wyng Wai

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation "Three Essays in Urban and Regional Economics" contains three chapters which explore urban and regional economics. The first chapters focuses on examining the effect of stadiums on congestion; the second chapter on the effect of military base closures on the housing market; and the third chapter is a meta-analysis on historical instrumental variables.

The first chapter examines the effect of National Football League games on traffic congestion in Cincinnati, Ohio; Seattle, Washington; and Santa Clara, California during the 2018 and 2019 seasons. By linking sporting events to traffic congestion, this paper provides the mechanism for stadiums generating additional …

Scene Classification Of Remote Sensing Image Based On Multi-Path Reconfigurable Neural Network, Wenyi Hu, Chunjie Lan, Tian Chen, Shan Liu, Lirong Yin, Lei Wang

Electrical & Computer Engineering Faculty Publications

Land image recognition and classification and land environment detection are important research fields in remote sensing applications. Because of the diversity and complexity of different tasks of land environment recognition and classification, it is difficult for researchers to use a single model to achieve the best performance in scene classification of multiple remote sensing land images. Therefore, to determine which model is the best for the current recognition classification tasks, it is often necessary to select and experiment with many different models. However, finding the optimal model is accompanied by an increase in trial-and-error costs and is a waste of …

Repealing Single-Family Zoning Is Not Enough: A Proposal For Removing Existing Parallel Private Covenants For Violating Public Policy, Gerald Korngold

Articles & Chapters

The United States is currently suffering a pervasive and unsettling shortage of housing and increased housing unaffordability. Rents are at an all-time high, which has a disproportionate impact on people of color and people earning lower incomes as they are more likely to rent rather than owns their homes. Moreover, people solidly in the middle class are finding it increasingly difficult to purchase residences within their budgets.

Critics have identified “single-family zoning”—allowing only one single-family home per lot--as a major cause of housing supply and affordability problems. In response, a handful of states and cities have recently passed legislation that …

Potential Landscape Connectivity For Invasive Wild Pigs (Sus Scrofa) Across The Northern Prairies Of North America, Corey J. Kramer, Melanie R. Boudreau, Ryan Powers, Kurt C. Vercauteren, Ryan S. Miller, Ryan K. Brook

United States Department of Agriculture Wildlife Services: Staff Publications

Understanding landscape scale connectivity is an essential component in the management of invasive species since connectivity facilitates their invasion potential. Invasive wild pigs (Sus scrofa) are among the most prolific invaders on the planet, causing billions of dollars in agricultural and environmental damage annually. Newly introduced to Canada in the 1980s, we examined wild pig invasion potential across the northern prairies from western Canada into the currently wild pig-free northern U.S. states. We used GPS collar data collected in the Canadian prairies to quantify resource selection and incorporated results into an electric circuit theory framework to evaluate potential …

Enhancing Terrain Creation In Unity With A Hybrid Modular Tool: Integrating Procedural Generation And Manual Input For Optimized Design Flexibility And Efficiency, Kewen Huang

Dartmouth College Master’s Theses

Digital terrain creation in Unity, especially for games, typically requires extensive manual effort, which is time-consuming and inefficient. Although procedural generation offers a systematic alternative, it often lacks the precision needed for specific design requirements, such as exact path or water body placements. This study introduces a novel modular tool that integrates manual input capabilities with automated procedural generation, aiming to combine the efficiency of procedural techniques with the precision of manual methods. The tool is designed for use within Unity, allowing for detailed customization and adjustments. Comprehensive user testing was conducted with 21 participants. The effectiveness of the tool …

Legacy Of Labour: The Impact Of Parental Occupations On Children’S Careers Choices And Income Inequality, Swapnil Landge

Publications and Research

This paper investigates how intergenerational occupational mobility and self-selection into occupations are influenced by the occupations of parents. The results demonstrate that children who pursue their parents’ occupations, particularly those in the lowest earnings percentiles, are more negatively self-selected compared to those whose parents are in the highest earning deciles. In particular, 65% of the children who pursue their parents’ occupation in Decile 1, 49% in Decile 2, 32% in Decile 3 and 26% in Decile 4 would have achieved higher productivity and earned higher earnings in high-income occupations (specifically in Decile 10 occupations). In contrast, children from high-income backgrounds …

Baaf: Bishop Airfield’S Contribution To The ‘Greatest Generation’, Jack Fisher

Eastern Sierra History Journal

The Dec. 7, 1941, Pearl Harbor attack changed everything in America including the Owens River Valley where most of its landing fields became sites for pilot training. One of these was the Bishop (CA) Air Field, leased by the Army from Inyo County effective June 10, 1942. It was was designated a tactical military facility and its history, hitherto untold, forms the basis of this article.

A Matter Of Facts: The Evolution Of Copyright’S Fact-Exclusion And Its Implications For Disinformation And Democracy, Jessica Silbey

Faculty Scholarship

The Article begins with a puzzle: the curious absence of an express fact-exclusion from copyright protection in both the Copyright Act and its legislative history despite it being a well-founded legal principle. It traces arguments in the foundational Supreme Court case (Feist Publications v. Rural Telephone Service) and in the Copyright Act’s legislative history to discern a basis for the fact-exclusion. That research trail produces a legal genealogy of the fact-exclusion based in early copyright common law anchored by canonical cases, Baker v. Selden, Burrow-Giles v. Sarony, and Wheaton v. Peters. Surprisingly, none of them …

The Role And Position Of Dual Credit In P-20 Education, Aaron Heinzmann

Murray State Theses and Dissertations

The trend in dual credit enrollment and deployment in secondary and postsecondary institutions has been steadily increasing over the last few decades. All 50 states have some form of dual credit that provides opportunity for secondary students to accelerate through their postsecondary pathways by earning college credits while still in high school. Students in dual credit can expect to achieve higher grade point averages in college, finish their degrees or certificates sooner, and realize postsecondary cost savings. As dual credit continues to permeate the P-20 landscape, educational leaders consider and continue to realize the benefits and drawbacks of accelerated collegiate …

In A Hell Of Our Own Creation: Spatial Context And The Wehrmacht’S Genocidal War In Eastern Europe, 1941–1943, Charles Joseph Calcaterra

Master's Theses and Doctoral Dissertations

A multitude of social, ideological, psychological, and environmental factors encouraged German servicemen to willingly commit atrocities in Eastern Europe during the Second World War. How should historians contextualize which factors held greater influence over servicemen deployed to different sectors of the vast Eastern Front? Charles Calcaterra highlights soldiers’ responses to their surrounding environments—the landscape of Eastern Europe—to explain why frontline divisions killed and destroyed indiscriminately in accessory to the Holocaust while rearguard personnel socially justified roundups, executions, and the horrid maltreatment of Red Army prisoners of war. Through the lens of military geography, the spatial contexts that fostered frontline units’ …

Chinese Fintech Goes Global: Political Challenges And Business Strategies, Yujia He

Patterson School of Diplomacy and International Commerce Faculty Publications

Fintech (the application of digital technology to financial services) has witnessed unprecedented growth, bringing significant implications for the financial system and sustainable development.1 The Financial Stability Board, an international body that monitors and makes recommendations about the global financial system, defines fintech as “technologically enabled financial innovation that could result in new business models, applications, processes, or products with an associated material effect on financial markets and institutions and the provision of financial services.”2 The use of technology in finance is certainly not new—consider the growth of electronic banking and high-frequency trading in the early 2000s. In the past two …

Time-Resolved Electromagnetic Near-Field Scanning: Dual Sparse Sampling In Time And Space, Yanming Zhang, Peifeng Ma, Lijun Jiang, Steven Gao

Electrical and Computer Engineering Faculty Research & Creative Works

Time-resolved electromagnetic near-field scanning plays a pivotal role in antenna measurement and unraveling complex electromagnetic interference and compatibility issues. However, the rapid acquisition of high-resolution spatio–temporal data remains challenging due to physical constraints, such as moving the probe position and allowing sufficient time for sampling. This article presents a novel hybrid approach combining kriging for sparse spatial measurement, compressed sensing (cs) for sparse temporal sampling, and dynamic mode decomposition (dmd) for comprehensive analysis of the dual-sparse sampling electromagnetic near-field data. We leverage cs to optimize sparse sampling in the time domain and latin hypercube sampling to guide the probe position …

Coupling-Informed Data-Driven Scheme For Joint Angle And Frequency Estimation In Uniform Linear Array With Mutual Coupling Present, Yanming Zhang, Wenchao Xu, A. Long Jin, Min Li, Peifeng Ma, Lijun Jiang, Steven Gao

Electrical and Computer Engineering Faculty Research & Creative Works

This paper proposes a novel coupling-informed data-driven algorithm tailored for the concurrent estimation of frequency and angle within a uniform linear array (ULA), while addressing the complicating influence of mutual coupling. Leveraging the hybrid dynamic mode decomposition (DMD) methodology, termed as averaged DMD, we incorporate moving average techniques to achieve effective denoising. The averaged DMD further decomposes the received signal into eigenvalues and corresponding eigenvectors. The frequency information is derived from the eigenvalues and the corresponding eigenvectors represent the steering vectors of sources. Subsequently, mutual coupling is informed into the calibration of the steering vector for each source. Specifically, the …

“I’M Especially Sorry To Those Impacted”: Conventional Visions Of Leadership In The 2022/2023 Tech Layoffs, Jared J. Watkins

Student Theses and Dissertations

In 2022 and 2023, over 400,000 employees in the technology sector were laid off. This study conducted a thematic analysis using coding on memos announcing layoffs sent by leaders at Meta, Google, and Microsoft in late 2022 and early 2023. This study also conducted an analysis of layoff memos sent by leaders of Google and Microsoft in 2009 for comparison. Key findings include that writing to multiple stakeholders in the 2022/2023 memos produced novel contradictions and paradoxes that may impede employee sensemaking, that 2022/2023 memos used more passive and distancing language that disconnected the leader from the layoff decision and …

Skipresnet: Crop And Weed Recognition Based On The Improved Resnet, Wenyi Hu, Tian Chen, Chunjie Lan, Shan Liu, Lirong Yin

Electrical & Computer Engineering Faculty Publications

Weeds have a detrimental effect on crop yield. However, the prevailing chemical weed control methods cause pollution of the ecosystem and land. Therefore, it has become a trend to reduce dependence on herbicides; realize a sustainable, intelligent weed control method; and protect the land. In order to realize intelligent weeding, efficient and accurate crop and weed recognition is necessary. Convolutional neural networks (CNNs) are widely applied for weed and crop recognition due to their high speed and efficiency. In this paper, a multi-path input skip-residual network (SkipResNet) was put forward to upgrade the classification function of weeds and crops. It …

Additionally, this paper proposes a pathway for automating these techniques to streamline inspection processes and improve implementation in practical applications.

The "Upside-Down" River: Trends In Total Nitrogen, Total Phosphorus, And Microcystin Concentration In The Klamath Basin, 2010-2021, Kayla M. Fitzpatrick

Cal Poly Humboldt theses and projects

The Klamath River tends to experience impaired upstream water quality, which improves downstream. Although this consensus is accepted, an updated spatiotemporal analysis of certain water quality parameters has not been conducted since 2017. With four of the Klamath River’s dams slated for removal by the end of 2024, it is critical to have an updated assessment of current water quality conditions from which to compare conditions following dam removal. In this study, total nitrogen (TN), total phosphorus (TP), and microcystin data from 2010-2021 were analyzed to determine concentration trends from Link Dam to the Klamath River Estuary.

Concentrations of TN …

Scale And Habitat Effects On Measurement Of Streptomyces Biogeography And Biodiversity, Terilyn A. Stoflet

Cal Poly Humboldt theses and projects

Bacteria in the genus Streptomyces are detected in most soils around the world, as well as on and in seeds, plants, animals, insects and the wind. Currently, more than 700 valid species of Streptomyces have been identified worldwide. Streptomyces produce the majority of antibiotics, antivirals and antifungals, as well as important agricultural bioactive molecules due to their unique genetic capabilities. Their distinct genetic abilities allow them to produce an unlimited amount of biosynthetic gene clusters, or BGC’s. Although many compounds come from Streptomyces, scientists have not discovered the biogeographic patterns of this genus. The biogeography of Streptomyces is a …

A Post-Colonial Criticism Of Ernest Callenbach's Ecotopia, Kaitlyn R. O'Dell

Cal Poly Humboldt theses and projects

The representation of Indigenous land-based cosmologies within Ernest Callenbach’s Ecotopia communicates a real perception of our world through the constructed imaginative society within this speculative fiction novel. Ecotopia is an alternative Pacific West Coast society that counters the dominant United States model in its holistic and green approach. This green society relies heavily on Indigenous ideology but lacks actual Indigenous voices or communities within this white idealized society. This research provides an example of the deconstruction of this popular novel to its main problematic components, establishing why the use of Indigenous beliefs and values can cause negative implications to the …

“Bad At Reading”: Narratives Of Boys With Negative Reading Self-Concept, Aimee Talmadge

Cal Poly Humboldt theses and projects

There is a clear and consistent gender gap between students who view themselves as readers and those who do not (Love & Hamston, 2003). Overwhelmingly, young men report a lower self-perception of their ability and interest in reading and literacy, and this in turn impacts their growth and motivation in literacy learning. Through this study, I interviewed six students, specifically male high school students who self-identified as bad at reading or disliking reading. Through one-on-one interviews and focus groups, I explored how they viewed themselves as “non-readers” and why their reading self-perception is negative. The findings show how the lack …

Adapting And Validating A Survey To Assess Host Communities Support For Migration, Jhon G. Botello, Katherine Palacio, Erika Frydenlund, Humberto Llinás, Jose Padilla

VMASC Publications

Migration presents challenges to receiving communities, as it tests their ability to respond to unexpected expenditures and social stresses. Evaluating the local impact of rapid and substantial migration flows is difficult due to the absence of a validated instrument for assessing community support for migration. Our study adapted and validated a Support for Migration Assessment survey (SMA) based on Social Exchange Theory (SET). The validation of the SMA contributes in two significant ways. First, it establishes an instrument that enables the assessment of support for migration (SFM) by considering community-level factors: trust in institutions (TII), overall community satisfaction (OCS), and …

Faculty Research, Scholarly, and Creative Activity

Understanding timing and distribution of virus spread is critical to global commercial and wildlife biosecurity management. A highly pathogenic avian influenza virus (HPAIv) global panzootic, affecting 600 bird and mammal species globally and over 83 million birds across North America (December 2023), poses a serious global threat to animals and public health. We combined a large, long-term waterfowl GPS tracking dataset (16 species) with on-ground disease surveillance data (county-level HPAIv detections) to create a novel empirical model that evaluated spatiotemporal exposure and predicted future spread and potential arrival of HPAIv via GPS tracked migratory waterfowl through 2022. Our model was …

Towards A Context-Contingent Stage Theory Of Entrepreneurial Opportunity: Introducing The Petii Model, Xiaohong Iris Quan

Faculty Research, Scholarly, and Creative Activity

Understanding opportunity is a crucial aspect of entrepreneurship research. Existing studies have extensively examined individual factors in facilitating entrepreneurial activities such as new venture creation. Although there are some discussions on contextual factors, few connect context with the origin of entrepreneurship—opportunity. Recognising the objectivity of entrepreneurial opportunity, this theoretical article first proposes two types of opportunities—innovative opportunity and imitative opportunity—to understand the nature of opportunity. It then proposes a systematic framework—the PETII (Population, Economic status, Technological advancement, Industry life cycle, Institutions) model—to analyse the role of context in the distribution of opportunity. Furthermore, it examines how both objective contextual factors …

Nations have committed to reductions in the global rate of species extinctions through the Sustainable Development Goals 14 and 15, for ocean and terrestrial species, respectively. Biodiversity loss is worsening despite rapid growth in the number and extent of protected areas, both at sea and on land. Resolving this requires targeting the locations and actions that will deliver positive conservation outcomes for biodiversity. The Species Threat Abatement and Restoration (STAR) metric, developed by a consortium of experts, quantifies the contributions that abating threats and restoring habitats in specific places offer towards reducing extinction risk based on the IUCN Red List …

Abalones At Risk: A Global Red List Assessment Of Haliotis In A Changing Climate, Howard Peters, Gina M. Ralph, Laura Rogers-Bennett

Biological Sciences Faculty Publications

There is increasing awareness that marine invertebrates such as abalones are at risk from the combined stressors of fishing and climate change. Abalones are an important marine fishery resource and of cultural importance to Indigenous and non-Indigenous people. A highly priced marine delicacy, they are inherently vulnerable: individuals are slow-growing and long-lived and successful reproduction requires dense assemblages. However, their global conservation status is poorly understood. Using IUCN Red List methodology, we assessed the extinction risk to all 54 species of abalone (genus Haliotis). Of the 21 fished commercially for human consumption either now and/or in the past, 15 …
