Supply Chain Sustainability: Understanding The Financial Impact, Matthew J. Guinn

EURēCA: Exhibition of Undergraduate Research and Creative Achievement

The purpose of this study is to determine if there is a differential impact on the financial performance of a company between environmental and social events.

This study uses a randomization of publicly traded companies within specific, pre-determined SIC codes, which is a collection of 66 companies, split between manufacturing and retail, to get the most accurate representation.

This study utilizes multiple regression models via STATA to analyze data compiled from the Wharton Research Database Services (WRDS) utilizing the MSCI ESG KLD, and Bloomberg, to analyze the percent increase in stock price which is the overarching models independent variable. Then, …

Spatial Analysis Of Mountaintop Mining's Impact On Water Quality, Samantha Cahill

EURēCA: Exhibition of Undergraduate Research and Creative Achievement

Mountaintop coal mining (MTM) has been shown to have negative effects on both biological communities and water quality downstream of mining. Impacts of MTM can still be seen decades after the mining has ended, leading to the conclusion that the cumulative effects of mining last decades after the mining has ended. Here, I aim to analyze the effects of MTM on both water quality and benthic macroinvertebrates in streams of the Southern Appalachian Mountains in Kentucky. I combine a remotely sensed mining landcover product with data on water quality parameters and stream macroinvertebrate communities from state and federal monitoring programs …

Archaeometric Approaches To The Roman Near East, Gayatri Nandwani

EURēCA: Exhibition of Undergraduate Research and Creative Achievement

The purpose of my research this summer has been to participate in a full suite of archaeometric and geoarchaeological analyses, particularly as they are applied to sedimentology. The first section of my research has focused on an introduction to these procedures at ARL including laboratory safety procedures, proper sample collection and processing methods, and introduction to methods and purposes for a variety of laboratory analyses including grain size distribution analysis using a state of the art Malvern Mastersizer 3000 laser diffraction particle size analyzer, organic matter and inorganic carbon analysis, and microartifact analysis. During the field collection phase I worked …

Modeling Adsorption And Diffusion Of Atomic Oxygen On The Ag(111) Surface Using Kinetic Monte Carlo Simulations, Seth Spencer Street, Sharani Roy, Sara Isbill

EURēCA: Exhibition of Undergraduate Research and Creative Achievement

Oxidized silver surfaces are widely used as industrial heterogeneous catalysts to oxidize small organic compounds, such as ethylene. While surface-adsorbed oxygen is known to participate in catalysis, it has been suggested that ‘subsurface’ oxygen adsorbed in the near-surface region of silver also plays important roles in surface reconstruction and reactivity. However, the formation, motion, and chemical behavior of subsurface oxygen in silver are not well understood. In the present work, a kinetic Monte Carlo (KMC) simulation has been developed using the Python programming language to computationally model the diffusion kinetics of atomic oxygen (AO) at the Ag(111) surface. This simulation …

Frequency Of Hemlock Woolly Adelgid Information Provided In The Media: Impacts, Ecology, And Citizen Outreach, Anna Killeen Cameron, Casey Fellhoelter, Bevin Hardy, Lucas Smith

EURēCA: Exhibition of Undergraduate Research and Creative Achievement

An analysis of 165 media articles about the hemlock woolly adelgid (HWA), an invasive insect killing native hemlocks in eastern North America, was undertaken to determine possible influences of the public’s desire and ability to help with invasive species prevention and control. All of the articles mention at least one of the following: HWA impacts to ecosystems (55.2%), hemlock characteristics (47%), and the value of hemlocks (38.8%). Articles that mention HWA impacts and hemlock value also mention associated topics such as subsequent impacts from hemlock loss to shade and temperature control of forests and streams, trout and recreational fishing, and …
