Ai Art: Artists’ Best Friend Or Mortal Enemy?, Ethan Gabrys
Ai Art: Artists’ Best Friend Or Mortal Enemy?, Ethan Gabrys
Tredway Library Prize for First-Year Research
This paper analyzes the impacts and implications of generative AI software on art and examines the ethics of using such tools. Through the argument that careless use of these tools presents a danger to the art world as they risk devaluing human expression, Gabrys states that “as what it means to be human changes with each generation, new artists express sentiment through their art. Art has the ability to tell us about the human experience.” He concludes that the use of AI tools takes the skill and sentiment of human artists out of the equation, begging the question: if the …
The Impact Of Shredders On Leaf Decomposition In The Silver Creek Watershed, Charlie Zielinski
The Impact Of Shredders On Leaf Decomposition In The Silver Creek Watershed, Charlie Zielinski
Environmental Studies: Student Scholarship & Creative Works
The carbon released from leaf decomposition plays a critical role in the riparian ecosystem and aquatic food web. By testing rates of leaf decomposition in urban streams we can survey the health of a watershed by sampling the carbon release amidst key locations in the area. In this study, we had two objectives: The assessment of the role of shredder macroinvertebrates in leaf decomposition, and the assessment of leaf decomposition rates across sites in Silver Creek. This project is part of the long term assessment of Davenport streams conducted by Augustana College's Upper Mississippi Center. We hypothesized that by excluding …
Structural Geology And Cenozoic Deformation: Western Northern Range, Trinidad, Abigail Faye Clark
Structural Geology And Cenozoic Deformation: Western Northern Range, Trinidad, Abigail Faye Clark
Geology: Student Scholarship & Creative Works
The Northern Range, Trinidad underwent deformation due to oblique collision of Caribbean plate with northern South America, which was then followed by transform plate motion. Deformation began in the late Miocene when sedimentary protoliths were ductility deformed and metamorphosed to greenschist facies; this event and subsequent transform deformation drove exhumation of these rocks to the surface and created their high topography. This project provides constraints of the structural history of the western Northern Range where bedrock mapping and structural analyses are most complete. Initial geologic mapping of Northern Range, which continued from the 1950s,1960s, and 1990s, focused on attempting to …

Land Use Effects On Fish Assemblages In Mississippi River Tributaries In Scott County, Ia And Rock Island County, Il, Benjamin Ford, Kevin Geedey
Urban Watershed Project
Fish assemblages are viable indicators of stream quality because they respond predictably to changes in abiotic and biotic factors, such as habitat and water quality, and human exploitation and species additions. In this a study we examined the relationship between fish abundance, diversity, and IBI (Index of Biotic Integrity), and urban and agricultural land use in Scott County, IA and Rock Island County, IL. Fish were sampled during the summer of 2021 within 12 local watersheds, which contain a variety of land use types. We followed a standardized sampling method of a single pass with a backpack electrofishing unit through …
Provenance Of The Northern Range, Trinidad Using Detrital Zircon U-Pb Geochronology: Implications For Northern South American River System Paleogeography, Cheyenne Bartelt
Provenance Of The Northern Range, Trinidad Using Detrital Zircon U-Pb Geochronology: Implications For Northern South American River System Paleogeography, Cheyenne Bartelt
Geology: Student Scholarship & Creative Works
The Northern Range of Trinidad is located in a key area for evaluating the Mesozoic-Cenozoic evolution of the Caribbean and South American plates. Here, we present detrital zircon U-Pb geochronology for 2391 grains from ten samples collected from metasedimentary rocks of the Northern Range. These data are used to bracket the maximum depositional age of the fossil-poor metasedimentary rocks from the Northern Range and to investigate the provenance of their sedimentary protoliths. Detrital zircon ages range between 3136.5 ± 22.9 Ma and 139.0 ± 5.4 Ma, reflecting apparent contribution from a variety of crustal affinities; however, since the youngest ages …

Assessment Of The Negative Role Amur Honeysuckle Has On Urban Forest Diversity, Hayley Schlabowske, Paige Lundborg, Jason Koontz, Michael Reisner
Independent Research Projects
Lonicera maackii (Amur Honeysuckle), an invasive shrub species, has out-competed native species in urban riparian zones for decades due to its ability to receive more sunlight and it also secretes an allelochemical from its leaves that negatively impacts the ecosystems. Our research question is how does Lonicera maackii affect native plant species in the herbaceous understory? Five forest communities were sampled in Northwest Illinois. Sites were separated into four different categories with L. maackii only, Garlic Mustard (Alliaria petiolata) only, Neither invasive species, and sites where both occur. There were 12 sites for each of the four categories resulting in …
Late Amazonian Wind Regimes And Landscape Evolution In Northern Meridiani Planum, Mars, Thomas Stritch
Late Amazonian Wind Regimes And Landscape Evolution In Northern Meridiani Planum, Mars, Thomas Stritch
Geology: Student Scholarship & Creative Works
Aeolian process have dominated the lower latitudes of Mars for billions of years. Aeolian landforms can act as records of current and past climates and landscape evolution processes. The etched deposits of Meridiani Planum, a vast suite of layered bedrock extending from southwest Arabia Terra to Schiaparelli crater, have long been noted to have been eroded by aeolian processes. However, little detailed work on the aeolian landforms of Meridiani Planum beyond the Opportunity rover landing site has been done. In this study, I examine wind streaks, aeolian bedforms (including dunes and large ripples), and yardangs in a valley about 370 …
Deathtrap, Blake Traylor
Deathtrap, Blake Traylor
Vázquez-Valarezo Poetry Award
I could have titled this one "Bad Trip in an Elevator," but that would twist the poem away from its authenticity. You'll have to trust me on this one: this happened. Not in the usual sense, but in that fiction-is-truth-in-a-funhouse-mirror, postmodern Tim O'Brien sense. And hallucinogens were not involved, nor are they encouraged or condoned. (Do with that Wretched Passive Voice what you will.)
If the word "Deathtrap" didn't amuse me so much, I really could have run with the title "Tired." Or maybe "Very Tired" would have been better. And then there are always the big-hitters: "Fatigue," "Exhaustion," "Are …
Geochemical Analysis And Heat-Treatment Of Natural Sapphires From Madagascar And Tanzania In Oxidizing And Reducing Conditions, Lukas Karuza, Dr. Michael B. Wolf, Brian Konecke Phd
Geochemical Analysis And Heat-Treatment Of Natural Sapphires From Madagascar And Tanzania In Oxidizing And Reducing Conditions, Lukas Karuza, Dr. Michael B. Wolf, Brian Konecke Phd
Geology: Student Scholarship & Creative Works
Natural or synthetic sapphires can be heat-treated to improve the clarity by removing “silk” (inclusions) and to change color by introducing color-inducing elements (i.e., chromophores) into the lattice structure or changing their valency. Due to these reasons, sapphires can be heat-treated to increase their monetary value. Twenty natural blue (C1), 20 green (C2), and 20 clear (C3) sapphires from Madagascar and Tanzania were heat-treated in a muffle furnace in oxidizing and reducing conditions, from 1200 to 1600℃, for 10-hour soak time. In total, 5 experiments were conducted in which soak time remained constant: experiment 1 was performed at 1200℃, exp. …
Ecowomanism: A Solution To Climate And Social Injustice, Alexis K. Karon
Ecowomanism: A Solution To Climate And Social Injustice, Alexis K. Karon
Religion: Student Scholarship & Creative Works
The interconnections of climate justice and social inequalities are paired together in a concept named 'Ecowomanism'. Originally inspired by Melanie L. Harris, ecowomanism uses spiritual theologies, experiences, and memories to discuss the post-modern struggles that women of African and indigenous descent face in society, which can then find solutions to such injustices in a reconnection to nature. In this paper, I argue that adopting an environmental paradigm inspired by the spiritual theology of ecowomanism in the United States, which acknowledges the connection between oppression and violence against communities of color to the violence and domination of the environment, a more …

Late Jurassic Dinosaurs On The Move, Gastroliths And Long-Distance Migration, Josh Malone
Late Jurassic Dinosaurs On The Move, Gastroliths And Long-Distance Migration, Josh Malone
Geography: Student Scholarship & Creative Works
The Jurassic Morrison Formation of the Rocky Mountain and Colorado Plateau regions is famous for its dinosaur fossils. The Morrison Formation (150-157 Ma) is comprised mostly of sandstone and mudstone that was deposited in a terrestrial deposition system that included fluvial, paludal, and lacustrine environments. Paleocurrent data indicates that Morrison sediment was transported to the north and east. Within the Morrison Formation, we find exotic pebble and cobble-size durable clasts of quartzite, chert and vein quartz weathering out of the mudstone paleosols. We interpret these exotic clasts as gastroliths, carried within the gastric mills of dinosaurs. For this study, we …
Poisson's Equation, Ehren Braun, Andrew P. Sward
Poisson's Equation, Ehren Braun, Andrew P. Sward
Mathematics: Student Scholarship & Creative Works
This presentation deals with how to solve Poisson's Equation for a two dimensional plate. The numbers can be represented as heat, charge density, and gravitational force. This is a generalization of Laplace's Equation, which are steady state problems. In this problem, it is broken up into two simpler problems. For the first part, there are two ways of solving it since it is two dimensional. This presentation covers both ways of solving it using separation of variables, orthogonality, and partial differential equations. In addition, it shows how to solve the second part and finalize Poisson's Equation.

Chikungunya: India, Allison Harvey
Chikungunya: India, Allison Harvey
Global Issues in Public Health
A communicable disease is an infectious disease, transmissible by direct contact with an affected individual or the individual’s discharges, or by indirect means. The more direct contact people have, the more disease spreads explaining why larger populations have more outbreaks of communicable diseases. India, in particular, has one of the biggest population sizes and makes them susceptible to those diseases. Many can be fatal. However, other diseases, such as chikungunya, are also dangerous viruses that put specific populations at risk for health problems if infected. With chikungunya symptoms such as fever or rashes may develop. Some symptoms such as joint …
Cholera: Uganda, Emilie Verran
Cholera: Uganda, Emilie Verran
Global Issues in Public Health
The bacterium Vibrio cholerae, when ingested, infects the intestines and causes a communicable diarrhea disease called cholera. Outbreaks of cholera occur in areas with poor sanitation and sewage treatments where fecal material of an infected person contaminates the water. These areas include Southeast Asia, Haiti, and sub-Saharan Africa, including Uganda. From 2011-2016, an analysis of Ugandan cholera data showed ‘hot spots’ of cholera cases in fishing communities with incidence rates as high as 120-998 cases per 100,000 people. An analysis of these same districts from 2011-2015 showed an average Case-Fatality Ratio of 2.4%, with the worst district as high …
Low Vaccination Rates: Africa, Karen Ruiz
Low Vaccination Rates: Africa, Karen Ruiz
Global Issues in Public Health
Vaccination is a treatment that produces immunity, protecting individuals and general populations from infectious and often deadly diseases. Low vaccination rates have for a long time been a pervasive issue in the continent of Africa. There are many extenuating circumstances that become contributory causes for low rates of populations being vaccinated. These circumstances can be in relation to the health professionals and facilities that distributes vaccinations, lack of resources in health facilities, false determiners for children’s eligibility, etc. Other contributory causes concern the general environments in which people live. These contributory causes can present barriers for accessing health services and …

Climate Change: Antarctica, Marika Vi
Global Issues in Public Health
Climate change is a public health issue that affects the entire globe. These effects include the rising in sea levels, shrinking of mountain glaciers, accelerating ice melt, and shifts in flower and plant blooming. The cause of climate change is due to what is known as the “greenhouse effect.” This is where certain gases block heat from getting out of the atmosphere. The cause of this effect is due to many factors like the overuse of fossil fuels and overpopulation. The impact of climate change on the Antarctic, to be specific, is that it has been seen to affect the …
Dengue, Edward Ramos
Dengue, Edward Ramos
Global Issues in Public Health
The dengue virus puts one third of the world’s population at risk. Humans carry the virus and mosquitoes pick it up and are able to spread to more people. As long as there are mosquitoes near you there is the possibility that you could become infected with the dengue virus. However, people living in tropical areas that are poverty stricken are much more likely to bit by these mosquitoes and developed dengue fever. Things like mosquito netting and proper plumbing help lower the amount of these mosquitoes from biting people. There are very few treatments for when a person gets …
