Music Binding Symposium
(2024-04-16) Coulbourne, Mark; Norman, Kim; Carli, Alice; Quintilian, Steve; Foley, Michael; Shirts, Peter; Risseeuw, Katherine
On April 16th the ALA/Core Preservation Administrators Interest Group and the Music Library Association Preservation Committee met for an online symposium on the binding, preservation and care of music scores. We have the list of panel presenters below, and we discussed why we bind music scores, binding decision trees, formats and treatments (with examples), budgets and advocacy, as well as the latest news on commercial binding. There was time for Q&A along with numerous examples of music scores. Presenters included: Alice Carli - University of Rochester Michael Foley - University of California, Berkeley Dan Lopata - University of Rochester Steve Quintilian - University of Maryland, College Park Katie Risseeuw - Northwestern University Peter Shirts - Emory University

Skibbereen, Ireland: A Legacy of the Famine
(2024) Weikert, Emma; Brighton, Stephen
The Irish Potato Famine began in the mid-19th century, claiming the lives of millions. The Famine forever changed the culture and sociopolitical relations of Irish people, and these changes are reflected in the graveyards in the past and present. Symbols, imagery, and types of grave markers give insight into the ideologies of the time they were placed there. I visited three graveyards in West Cork in the summer of 2023 and examined databases of graveyards, to compare grave markings and graveyards before, during, and after the Famine. The question was posed: What are the long-term cultural implications of the famine, and how does this manifest in graveyards?

Quantum Finance: Exploring Asset Management with QAOA
(2024) Henkle, Evan; Igur, Vismay; Karnik, Sara; Velaga, Sourabh; Jabeen, Shabnam; Khan, Alex
Quantum computers are becoming more and more applicable to a variety of applications due to their ability to exponentially speed up computation. This project aims to utilize quantum technology to build a Quantum Approximation Optimization Algorithm (QAOA), to redefine portfolio optimization in finance. We aim to conduct a series of simulations to evaluate the effectiveness of our quantum based portfolio strategy, and compare the outcomes against those achieved through traditional optimization methods. Our preliminary research indicates that the quantum approach may result in faster and higher quality portfolio solutions, leading to more profitable and risk averse investments. By translating the challenge of finding the optimal combination of assets - balancing risk and return - into a problem that can be solved by quantum computing, we unlock new possibilities for financial analysis and decision making.

Exploring Olfactory Cues: Behavioral Responses in Cichlid Juvenile to Food and Amino Acid Stimuli
(2024) Leary, Maurice; Gable Parker, Coltan; Juntti, Scott
Cichlid fish have achieved a uniquely high rate of speciation, providing researchers the opportunity to better understand the sensory systems associated with speciation. Chemosensation, which includes both taste and olfaction and is used to detect food, must have evolved as cichlids evolved different lifestyles and diets. However, the specific neural mechanisms associated with chemosensory food detection in cichlids have not been discovered. In this experiment, we aimed to determine if cichlid juveniles show behavioral preference for food associated olfactory cues when presented with two types of stimuli: amino acids and food extract. We expect that both cues should be sufficient in evoking behavioral preference, as determined by time spent in odor compared to clean water, which would confirm the ability to confirm preference for food olfactory cues in cichlid juvenile. I tested a total of 28 cichlid juvenile, and their results revealed no overall significant preference when introduced to an olfactory cue. Nonetheless, we did observe 100% of fish spending over 50% of time in food extract order when administered, suggesting further research is required to determine if a possible stage in development is crucial in confidently proving this. Further research may entail an assay with a simpler food delivery system, a finer control of water flow, and histological studies in comparison of cichlid juvenile in various stages of development, as to determine significant olfactory or brain tissue differences.

Russian Wealth and The Invasion of Ukraine: Evidence from the Bank for International Settlements
(2024) Bopst, Connor; Reck, Daniel
This paper uses public bilateral deposit data released by the Bank for International Settlements to analyze the effect of Russia's invasion of Ukraine in February 2022 on Russian wealth held abroad. I find a sharp spike of over $22 billion, or 66%, in Russian nonbank loans and deposits held abroad from quarter 4 of 2021 to quarter 1 of 2022. This spike in loans and deposits fully subsides by quarter 2 of 2022. I quantify the spike mathematically and note its exemplary nature. I examine the Russian sectors that are driving the trend, finding a steep decline in Russian nonbank deposits held by households and a spike and partial reversion in deposits held by nonbank financial institutions. Deposits from non-financial corporations exhibit a spike and subsequent fall to lower than pre-invasion levels. I walk through potential explanations for these trends, beginning with a marked decline in Russian loans and deposits in Switzerland that co-trends with Russian household deposits. I further document increases in Russian loans and deposits in Belgium that start after Euroclear began to store seized Russian assets. Lastly, I note a spike and full reversion in Russian loans and deposits held in the US and discuss the possibility that the liquidation of US multinationals could cause the deposit behavior seen in the US-Russia series. This paper has implications for the offshore wealth and capital flight literatures and the effectiveness of the sanctions imposed on Russian Oligarchs after Russia's invasion of Ukraine.
