Death After: A Visualization Of Death In A Digital Medium, Cole Yamamura

WWU Honors College Senior Projects

NOTE: a free version of GameMaker is required to run this game and can be downloaded from https://gamemaker.io/en/download.

DEATH//AFTER is an original video game, generated by Cole Yamamura, in which a masked figure invites users to engage in one last encounter before their demise. Much like life, the figure chooses the game but the user chooses how to move through it. Depending on the user’s choices, the figure reveals additional challenges or one of several possible endings. A limited, unfamiliar deck of cards further complicates the matter, and the masked figure neither forgives nor undoes the user’s errors.

DEATH//AFTER seeks …


Evaluating The Efficiency Of Soil Amendments To Mitigate The Leaching Of Copper Nanopesticides, Brianna Benner Apr 2024

Evaluating The Efficiency Of Soil Amendments To Mitigate The Leaching Of Copper Nanopesticides, Brianna Benner

WWU Honors College Senior Projects

As pesticides are necessary to meet current and future agricultural needs, nanopesticides have seen increased use resulting from their more targeted application at lower doses. Copper-based nanopesticides have demonstrated efficacy but there are also concerns about their potential toxicity to aquatic species. This unintended toxic exposure resulting from agricultural runoff containing these nanopesticides can be mitigated through the use of soil amendments. In this study, biochar and chitosan were investigated as soil amendments, as they can bind metals and nutrients; however, there are still open questions about how their effective they are in different soil types and in relation to …

Hydrophobicity Of Factor Viii On Membrane Binding, Mady Jacobs Apr 2024

Hydrophobicity Of Factor Viii On Membrane Binding, Mady Jacobs

WWU Honors College Senior Projects

Factor VIII (FVIII) plays a crucial role in our body’s ability to prevent blood loss. This function comes from its ability to bind membranes and enhance catalytic function of other proteins. Membrane binding of FVIII relies on hydrophobic residues located at the lower C2 domain in a region named the PS head group. This study looks at how the enhancement of the hydrophobicity of this site can impact the protein binding ability to membranes. Specifically mutating the residues leucine at residue 2251 in the PS head group to phenylalanine, the study uses BLI instrumentation to determine whether this mutation can …


Artificial General Intelligence And The Mind-Body Problem: Exploring The Computability Of Simulated Human Intelligence In Light Of The Immaterial Mind, Caleb Parks Apr 2024

Artificial General Intelligence And The Mind-Body Problem: Exploring The Computability Of Simulated Human Intelligence In Light Of The Immaterial Mind, Caleb Parks

Senior Honors Theses

In this thesis I explore whether achieving artificial general intelligence (AGI) through simulating the human brain is theoretically possible. Because of the scientific community’s predominantly physicalist outlook on the mind-body problem, AGI research may be limited by erroneous foundational presuppositions. Arguments from linguistics and mathematics demonstrate that the human intellect is partially immaterial, opening the door for novel analysis of the mind’s simulability. I categorize mind-body problem philosophies in a manner relevant to computer science based upon state transitions, and determine their ramifications on mind-simulation. Finally, I demonstrate how classical architectures cannot resolve so-called Gödel statements, discuss why this inability …


Early Report Of A Microcosm Of The Fourth Major Global Bleaching Event: A Comprehensive Survey Of Coral Bleaching At Chumbe Island Coral Park, Zanzibar, Christian Boudreaux Apr 2024

Early Report Of A Microcosm Of The Fourth Major Global Bleaching Event: A Comprehensive Survey Of Coral Bleaching At Chumbe Island Coral Park, Zanzibar, Christian Boudreaux

Independent Study Project (ISP) Collection

Coral reefs harbor a wealth of the biodiversity present in the ocean. They provide an array of ecological and economic services that make them crucial to the function of a healthy ocean and prosperous coastal communities. Due to an array of anthropogenic stressors, including an increase in ocean temperatures as a result of climate change, reefs have been devastated worldwide. This is, in large part, due to the process of coral bleaching, the expelling of symbiont algae which the coral needs to produce energy, for an extended period until death. This study surveyed bleaching and death at a deeper and …


Short-Term Larval Surveys Reveal Rainy Season Breeding Site Preferences Of Malaria Vector Anopheles Spp. In Zanzibar City, Kaeden K. Hill Apr 2024

Short-Term Larval Surveys Reveal Rainy Season Breeding Site Preferences Of Malaria Vector Anopheles Spp. In Zanzibar City, Kaeden K. Hill

Independent Study Project (ISP) Collection

Malaria is a serious illness that causes over 500,000 deaths annually worldwide, with Tanzania alone contributing to approximately 4% of those deaths. Malaria is caused by Plasmodium spp. parasites, and it is vectored by mosquitoes in the Anopheles genus. In Zanzibar City, the incidence of malaria has decreased over the past few decades due to standardized treatment protocols and public health interventions targeting adult mosquitoes. However, the incidence remains between 1-2%, with an increasing trend observed over the past few years likely stemming from continued exchange of Plasmodium spp. from other malaria-endemic areas. Because larvicidal strategies can be useful in …

Structural Responses To Land Use In Pollination Networks: Effects Of Biodiversity And Alien Plants In The Ecuadorian Chocó, Eric Abrahams

Independent Study Project (ISP) Collection

As a globally recognized hotspot of biodiversity, the Ecuadorian Chocó Andino region is extremely important for research and conservation. However, little research has been done regarding the mutualistic networks that sustain this ecosystem. The analysis of plant-pollinator networks helps us understand how ecosystems respond to change and is vital to conserving ecological productivity across multiple spatial scales. This study establishes a baseline for pollinator network structure across a land use gradient near the western montane cloud forest in Ecuador. Plants and pollinators were sampled along 11 transects in farms, communities, roads in the Río Manduriacu valley. Weedy herbs dominated overall, …

Kicking Up Dust On Utah's Off-Road Vehicle Trails: Pi-Swerl Assessment Of Anthropogenic Dust Emissions, Wyatt A. Wiebelhaus Apr 2024

Kicking Up Dust On Utah's Off-Road Vehicle Trails: Pi-Swerl Assessment Of Anthropogenic Dust Emissions, Wyatt A. Wiebelhaus

Honors Thesis

Upward trends in the use of off-highway vehicles (OHV) and the creation of new OHV trails facilitate an increase in soil disturbance and dust emissions in Utah. Anthropogenic destruction of soil crusts and the removal of vegetation by OHVs exposes soil and destroys soil structure, making the soil easier to erode by the wind. We used the PI-SWERL (Portable In Situ Wind Erosion Laboratory) to measure dust concentrations of disturbed and undisturbed soil. We tested soils at several popular OHV areas with landforms composed of sand dunes, playas, and Lake Bonneville sediments. Soil crust strength, grain size, and salinity were …

Chemistry and Biochemistry Faculty Publications and Presentations

The malting process takes one week to steep, germinate, and kiln barley to make malt. Making quality malt is critically important to achieve the desired attributes of the finished beer, and the process is time-intensive and costly. Malt quality is assessed by indicators including β-glucan quantity, α-amylase activity, Free Amino Nitrogen (FAN) content, and overall extract concentration in the finished malt. Here, we report Pulsed Electric Field (PEF) treatment of barley to accelerate malt production. A small-scale trial of 250 g to 1.00 kg barley, was evaluated for germination at two PEF treatment conditions, generically referred to as “low” and …

Effects Of Heterogeneous Data Sets And Time-Lag Measurement Techniques On Cosmological Parameter Constraints From Mg Ii And C Iv Reverberation-Mapped Quasar Data, Shulei Cao, Michal Zajaček, Bożena Czerny, Swayamtrupta Panda, Bharat Ratra

Physics Faculty Publications and Presentations

Previously, we demonstrated that Mg II and C IV reverberation-mapped quasars (RM QSOs) are standardizable and that the cosmological parameters inferred using the broad-line region radius–luminosity (R–L) relation are consistent with those determined from better-established cosmological probes. With more data expected from ongoing and future spectroscopic and photometric surveys, it is imperative to examine how new QSO data sets of varied quality, with their own specific luminosity and time-delay distributions, can be best used to determine more restrictive cosmological parameter constraints. In this study, we test the effect of adding 25 OzDES Mg II RM QSOs as well …

Shall We Place More Advanced Students In A Separate Class?, Shahnaz Shahbazova, Olga Kosheleva, Vladik Kreinovich Apr 2024

Shall We Place More Advanced Students In A Separate Class?, Shahnaz Shahbazova, Olga Kosheleva, Vladik Kreinovich

Departmental Technical Reports (CS)

In every class, we have students who are more advanced and students who are more behind. From this viewpoint, it seems reasonable to place more advanced students in a separate class. This should help advanced students progress faster, and it should help other students as well, since the teachers in the remaining class can better attend to their needs. However, empirically, this does not work: when we form a separate class, the overall amount of gained knowledge decreases. In this paper, we provide a possible explanation for this seemingly counterintuitive phenomenon.

Assessing The Efficacy Of The Washington Ban On Phosphorus Fertilizer, Pilar Deniston

WWU Honors College Senior Projects

Freshwater lakes are essential ecosystems, providing crucial services for humans, plants, and animals. However, eutrophication, a process driven by an excess of nutrients such as phosphorus, poses a significant threat to lake health and water quality. To mitigate excess phosphorus and eutrophication, many states, including Washington, have implemented bans on phosphorus-containing fertilizers. This study evaluates the efficacy of Washington State's 2013 phosphorus-containing fertilizer ban, focusing on 58 lakes in western Washington. This study organized, filtered, and analyzed data from multiple counties' monitoring programs to examine total phosphorus concentrations before and after the ban. Additionally, this study involved a land cover …
