The Mathematics Of Financial Portfolio Optimization Incorporating Environmental, Social, And Governance Score Information, Ian Driskill

Master's Theses

We numerically investigate the effects that Environmental, Social, and Governance (ESG) scores have on portfolio optimization with Modern Portfolio Theory assumptions and how ESG scores correlate with the market returns of a rated company's stock. Additionally, we review and analyze a research paper published in the Journal of Financial Economics regarding ESG investing titled “Responsible investing: The ESG-efficient frontier” by Pedersen, Fitzgibbons, and Lukasz. Our overall goal is provide insight for socially responsible inclined investors, to help them understand what ESG scores tell us and how those scores may effect their overall investment returns."

Exploration On Lysing Microalgae Using Pulsed Electric Fields, Fereshteh A. Bunk

Physics

With a dangerously and rapidly changing climate [1], people globally are desperate to reduce CO2 emissions and protect our environment as evidenced by global initiatives such as the United Nations’ Paris Agreement [2]. Traditional fossil fuel extraction and combustion was responsible for 74% of U.S. greenhouse gas emissions in 2019, which contributes to climate change, ocean acidification, extreme weather events, sea level rise, pollution, and health issues which contributed to 350,000 premature deaths in the U.S. in 2018 [3]. This motivates the search for alternative, more sustainable fuel production. There have been many new, more sustainable solutions to traditional fossil …

Hunting Without Grounds: Why Hsiao Fails To Justify Trophy Hunting, Kyle York

Between the Species

Trophy hunting is probably bad. Timothy Hsiao (2020), however, thinks that it isn’t bad. This is because he thinks that animals lack moral status. Other philosophers have tried to argue against the theoretical grounds upon which Hsiao denies moral status to animals. I suggest that Hsiao’s arguments for trophy hunting should be rejected simply because they have extremely unintuitive implications. They imply that it would be fine to play ‘panda-ball,’ a variation of baseball where players use panda cubs as bases and balls, or even to blow up planets full of panda cubs just for the fun of it. As …

Characterizing The Ecological Impacts Of Utility-Scale Solar Energy (Usse) On Fallowed Farmland, Amanda Gersoff

Master's Theses

Large-scale carbon-free energy generation projects such as utility-scale solar energy (USSE) arrays help mitigate the energy sector’s contribution to climate change and are rapidly expanding throughout the U.S. However, the expansion of USSE sites is associated with immediate and longer-term ecological impacts, many of which have yet to be assessed. Quantifying the ecological impacts of USSE arrays will help to identify synergies and trade-offs between energy generation and terrestrial conservation goals. The overall goal of this research is to characterize the ecological impacts of USSE sites located on fallowed farmlands in San Luis Obispo County, California in a seasonally explicit …

Comparison Of Scanning Electron Microscopy And Confocal Laser Microscopy For Tissue Surface Roughness Characterization, Tarnvir Dhaliwal

Master's Theses

It was found that the measurements captured by confocal microscopy and scanning electron microscopy had a statistically significant difference for bovine tissue. There was not a statistically significant for porcine and poultry tissue.

The intent of the study is to perform a comparative study to examine efficacy of two distinct technologies for a singular purpose: tissue surface roughness characterization. The two technologies compared are a confocal reflectance microscope and a scanning electron microscope. The comparison was made by comparing two surface roughness parameters [Ra and Rq] within ImageJ.

The study examined three different animal species [porcine, bovine, and poultry] to …

Automated Tree Mortality Detection Using Ubiquitously Available Public Data, Michael T. Huggins

Master's Theses

Understanding the dynamic interplay between fire severity, topography, and tree mortality, is crucial for predicting future forest dynamics and enhancing resilience against climate change-induced wildfire regimes. This thesis develops a multi-sensor approach for automated estimation of tree mortality, then applies it to examine trends in tree mortality over a six-year period across a fire affected study site in the Trinity River basin in Northern California. The Random Forest model uses publicly available USGS 3D Elevation Program Lidar (3DEP) and NAIP imagery as inputs and is likely to be easily adaptable to other landscapes. The model had a Receiver Operating Characteristic …

Two of the five sites were located along San Luis Obispo Creek, and three located along Stenner Creek. Criteria to evaluate these aquatic systems was provided by the Standard Operating Procedures of the Surface Water Ambient Monitoring Program, formulated by the State Water Resources Control Board. These procedures describe the methodology surrounding the collection of chemical, physical, and biological parameters of stream systems; streamflow, substrate, flow habitat, chemical water quality, and benthic macroinvertebrates are some of the criteria collected that allows …

Effects Of Anthropogenic Noise On The Provisioning Behavior Of Western Bluebirds And Artificial Light At Night On Nestling Development, Kerstin H. Ozkan

Master's Theses

Sensory environments are rapidly changing due to increased human activity in urban and non-urban areas alike. For instance, background sounds can interfere with parent-offspring communication and mask cues reflective of predation risk, resulting in elevated vigilance at the cost of provisioning. In chapter 1, we studied nestling provisioning behavior among Western Bluebirds (Sialia mexicana) in response to short-term (1 hr) and long-term (continuous exposure throughout nesting period) noise exposure. Provisioning rates were lower at nests exposed to short-term experimental traffic noise compared to exposure to ambient background sounds. Trial order strongly influenced provisioning behavior, with the decline in …

Stress Effects On The Growth Physiology Of Pacific Rockfishes (Sebastes Spp.): Negative Impacts Of Cortisol And Elevated Temperature Exposure, Hayley M. Mapes

Master's Theses

Fish experiencing stressful conditions increase production of the glucocorticoid hormone cortisol, which alters energy intake and allocation to help recover physiological homeostasis. Fish experiencing prolonged elevations of cortisol, however, often exhibit reduced somatic growth. While it has been shown previously in fish that cortisol inhibits anabolic growth processes in part via changes in endocrine growth hormone (Gh)/insulin- like growth factor-1 (Igf1) signaling, it is not fully understood which components of Gh/Igf1 pathways are modulated by cortisol. Here, we explored how cortisol influences the Gh/Igf1 system in blue rockfish (Sebastes mystinus) by administering exogenous cortisol and examining effects on …

Insights Into Cellular Evolution: Temporal Deep Learning Models And Analysis For Cell Image Classification, Xinran Zhao

Master's Theses

Understanding the temporal evolution of cells poses a significant challenge in developmental biology. This study embarks on a comparative analysis of various machine-learning techniques to classify cell colony images across different timestamps, thereby aiming to capture dynamic transitions of cellular states. By performing Transfer Learning with state-of-the-art classification networks, we achieve high accuracy in categorizing single-timestamp images. Furthermore, this research introduces the integration of temporal models, notably LSTM (Long Short Term Memory Network), R-Transformer (Recurrent Neural Network enhanced Transformer) and ViViT (Video Vision Transformer), to undertake this classification task to verify the effectiveness of incorporating temporal features into the classification …

Graphic Communication

Long Story Short and is a vintage up-cycling art brand. Our mission is to breathe new life into vintage pieces, crafting them into modern wearable art. As the name suggests, each creation tells a story while being revitalized for today’s fashion forward community.

Fast fashion and trend cycling has been a growing problem in today’s society. Things are going ‘in’ and ‘out’ quicker than they ever have. Trend cycling usually operates on a 20-year timeline. But, today’s sped up cycle encourages people to constantly over-consume in chase of the next cool thing. It’s unsustainable and an impossible chase. With a …

Spatial Drivers Of Soil Health In A Post-Fire Watershed, Reed Jd Williams

Master's Theses

Wildland fires are increasing in both severity and intensity leading to severe and lasting biogeochemical effects on soil. The CZU lightning complex started on August 16^th, 2020, and burned 86,509 acres causing severe social and ecological damage. To better understand the impact of fire on soil properties at the landscape scale, we created a digital soil mapping model with the inclusion of remotely sensed burn severity covariates. We combined a raster-stack of environmental covariates with rasters for fire severity and soil samples, to disentangle the relative contribution of fire to the spatial distribution of soil properties in the …

Coralai: Emergent Ecosystems Of Neural Cellular Automata, Aidan A. Barbieux, Aidan A. Barbieux

Master's Theses

Artificial intelligence has traditionally been approached through centralized architectures and optimization of specific metrics on large datasets. However, the frontiers of fields spanning cognitive science, biology, physics, and computer science suggest that intelligence is better understood as a multi-scale, decentralized, emergent phenomenon. As such, scaling up approaches that mirror the natural world may be one of the next big advances in AI. This thesis presents Coralai, a framework for efficiently simulating the emergence of diverse artificial life ecosystems integrated with modular physics. The key innovations of Coralai include: 1) Hosting diverse Neural Cellular Automata organisms in the same simulation that …

Effect Of Chloropicrin And Metam Sodium On Soil Nitrogen Dynamics In California Strawberry Production, Colin Timothy Koubek

Plant Sciences

California strawberries (Fragaria x ananassa Duch.) bring in ~3 billion yearly for the state's economy. Strawberry growers use fumigants like chloropicrin and metam sodium to manage a variety of soilborne diseases in conventional production. The yield-boosting effects of fumigation on strawberries are often attributed to disease management, but the ‘fertilizer effect’ from mineralization may play an equally significant role. This experiment conducted in a grower field sought to find out the influence that fumigation had on the mineralization of soil organic nitrogen and if preplant fertilizer application affected early season nitrogen (N). There were six treatments: control, control with controlled …

Can Functional Traits Predict Turnover Of Alpine Plant Species In Yosemite National Park?, Brooke L. Wallasch

Biological Sciences

Alpine species are a useful tool for predicting the effects of climate change on lowland species. A growing body of research has begun assessing the question of how alpine species will change in response to changing climate. In the study of alpine plant species, some researchers have begun exploring the idea that functional traits could be predictive of turnover in alpine plant communities. In this study, I used a species’-level approach to assess the ability of six functional traits (vegetative height, generative height, leaf thickness, leaf area, leaf dry weight, specific leaf area) to predict species turnover in alpine plants …

Ungrading: Reflections Through A Feminist Pedagogical Lens, Erin M. Eggleston, Shelby Kimmel

Feminist Pedagogy

Ungrading is a pedagogical approach in which no grades are given on any assignments. Instead, students are provided with many opportunities to submit work and gain feedback. The goal is to shift student focus from achieving a grade to growth as a learner and a person. As instructors, our ungrading approach utilized personalized learning plans, checkpoint reflections, and student-professor learning conferences to put agency in the hands of our students. We employed this method in upper-level biology and computer science courses and provide critical reflections here regarding our experiences and the connections between this approach and feminist STEM pedagogy tenets. …
