At The Death Of Architecture: Frank Lloyd Wright's Dreams Of America In Japan, Matthew L. Delgaudio

Binghamton University Undergraduate Journal

In 1832, French writer Victor Hugo declares the death of the edifice as a result of the totalizing popularity of Gutenberg’s printing press since the fifteenth century. American architect Frank Lloyd Wright would echo this sentiment to an intrigued Chicago audience almost 70 years later in his 1901 lecture, “The Art and Craft of the Machine.” The argument went that architecture, chief among the arts, would employ ornament, applied art, and symbolic meaning to capture and spread lasting imprints of human thought before the book usurped this position on account of its greater efficiency in accomplishing the same ends. While …

A Distinct Radial Acceleration Relation Across The Brightest Cluster Galaxies And Galaxy Clusters, Pengfei Li, Stacy S. Mcgaugh

Faculty Scholarship

Recent studies reveal a radial acceleration relation (RAR) in galaxies, which illustrates a tight empirical correlation connecting the observational acceleration and the baryonic acceleration with a characteristic acceleration scale. However, a distinct RAR has been revealed on brightest cluster galaxy (BCG) cluster scales with a seventeen-times-larger acceleration scale due to the gravitational lensing effect. In this work, we systematically explore the acceleration and mass correlations between dynamical and baryonic components in 50 BCGs. To investigate the dynamical RAR in BCGs, we derived their dynamical accelerations from the stellar kinematics using the Jeans equation through Abel inversion and adopted the baryonic …

A Design Science Approach To Investigating Decentralized Identity Technology, Janelle Krupicka

Cybersecurity Undergraduate Research Showcase

The internet needs secure forms of identity authentication to function properly, but identity authentication is not a core part of the internet’s architecture. Instead, approaches to identity verification vary, often using centralized stores of identity information that are targets of cyber attacks. Decentralized identity is a secure way to manage identity online that puts users’ identities in their own hands and that has the potential to become a core part of cybersecurity. However, decentralized identity technology is new and continually evolving, which makes implementing this technology in an organizational setting challenging. This paper suggests that, in the future, decentralized identity …

However, there is a lack of investigation into the complex processes occurring at the intersection of these two systems. This dissertation aims to fill that gap by building on previous research, organizational theory, and the growing area of punishment literature in criminal justice. The goal is to better understand how juvenile justice and child welfare systems organizationally manage dual system youth. Specifically, …

Catchment Water Storage Mediates River Flow Sensitivity To Climate Change, Brian Charles Brown

Theses and Dissertations

As patterns of precipitation and evapotranspiration change, human water security and aquatic ecosystem health depend on understanding how catchment characteristics interact with climate to control river flow. We tested factors that mediate sensitivity of river flow to fluctuations in climate using a set of 1,148 data-rich, climate diverse catchments in various parts of the world from 2001-2020. We extrapolated these results to an additional 2,012 catchments with sparser data. Using features such as vegetation, land use, hydrology, and local climate, we found that catchments with high aridity to runoff ratios (Fuh's parameter) had 380% higher runoff sensitivity to fluctuations in …

Mathematics Sciences: Faculty Publications

We study existence and uniqueness of Green functions for the Cheeger QLaplacian in metric measure spaces that are Ahlfors Q-regular and support a Q-Poincar´e inequality with Q > 1. We prove uniqueness of Green functions both in the case of relatively compact domains, and in the global (unbounded) case. We also prove existence of global Green functions in unbounded spaces, complementing the existing results in relatively compact domains proved recently in [BBL20].

Combating Trauma And The Immigrant Paradox In Schools, Emma Bergman

Honors Projects

Over time, research on immigrant populations has revealed a trend known as the immigrant paradox in which, the further generations get from the generation of immigration, the poorer their outcomes are in areas such as mental health, delinquency, substance abuse, and education. Though a definitive explanation for this trend has yet to be identified, prevailing theories include several social, familial, and community-based factors such as the impacts of bilingualism, parental expectations, biculturalism, co-ethnic peers, quality of schools, and community support. Little attention has been paid to individual factors such as mental health and trauma. The present study proposes the transgenerational …

Synthesis Of Trisubstituted Bismuth Complexes For Future Research, Cassidy Belk

Undergraduate Theses

Bismuth, a relatively inexpensive heavy metal with low toxicity, has the potential to be used in medicines and anticancer drugs. This project is exploring bismuth complexes with ligands based on chalcones, which are a type of small organic molecules with known anticancer properties. Preliminary results on a bismuth-chalcone complex indicate that substituted aryl bismuth complexes have better anticancer activity than triphenylbismuth or the chalcone ligand on its own. A series of trisubstituted bismuth molecules were synthesized using a BiCl₃ Grignard reaction under a nitrogen atmosphere with different substituents to provide electron donating groups, electron withdrawing groups or bulk. X-ray …

Geometries Gon Wild, Naat Ambrosino

Undergraduate Theses

A circle is mathematically defined as the collection of points a given distance away from a set point. Thus, the appearance of a circle varies dramatically across different metrics—for example, the taxicab metric (as popularized by Krause and Reynolds) has a circle that is a Euclidean square. As such, metrics can be partially defined by the appearance of their unit circles. This paper focuses on creating and analyzing an infinite set of metrics defined by their circles being regular polygons. Additionally, it provides a method of exactly generating a regular n-gon given a center, included point, and specified orientation.
