*dhéĝhōm,*héshr, and *wek (earth, blood, and speech): an archaeological, genetic, and linguistic exploration of Indo-European origins
Date: 2017-05-01
Creator: Lara Bluhm
Access: Open access
- This project investigates strategies for learning about prehistoric languages that have left no written records. It focuses upon the origins and expansion of the Indo-European language family (the world’s largest by total speaking population, today including most of the languages between Iceland and India) and its associated speakers, who likely emerged during the Neolithic from someplace in eastern Europe or western Asia. There are two primary hypotheses regarding the origins of these languages and the so-called Indo-Europeans themselves. In one, it is argued that they arose via the expansion of agriculture out of Anatolia and into Europe, c. 5000 BC. The other, and leading, hypothesis suggests instead that the languages spread through migrations of highly mobile pastoralists outward from the Black Sea steppes at the end of the Neolithic, c. 3000 BC. This project will explore the developing interface between archaeology, genetics, and linguistics in prehistoric resarch. There are three main chapters: (1) some background and historical context about Indo-European studies; (2) an examination of methodological interaction among archaeology, linguistics, and genetics; and (3) a survey of various archaeological, genetic, and linguistic data as they pertain to the Indo-Europeans and the above two hypotheses of their origins.

Eroding the Bedrock: The Future of Public Administration Without Chevron Deference
Date: 2024-01-01
Creator: Rose Keller
Access: Open access
- When Congress passes a bill, it produces words on a page. Who decides what those words mean? Historically, the onus of a statute’s interpretation has rested with the federal agencies charged with its implementation. The Chevron doctrine, a two-step standard that affords federal agencies significant latitude in interpreting their own enabling legislation, has been the applicable deference regime in statutory interpretation cases since 1984. Contrary to this tradition, recent Supreme Court jurisprudence has reasserted the primacy of the judiciary in statutory interpretation cases, often ignoring Chevron entirely. In 2023, the Court granted certiorari to Loper Bright Enterprises v. Raimondo, a case that explicitly asked the Court to consider overruling Chevron vs. NRDC, a foundational case in the field of administrative law. This thesis explores the implications of eroding deference to federal agencies through a case study of the Food and Drug Administration and two of its responsibilities. Ultimately, there are potentially negative consequences to limiting agency jurisdiction via eviscerating judicial deference that counsel a more discerning approach.
Activation of Hydrogen by Sterically Modulated Coinage Metal Catalysts via Mutual Quenching of Hard/Soft Acid/Base Mismatches

Creator: Zach Leibowitz
Access: Open access
- To mitigate the devastating environmental impacts of climate change in the coming decades, it is imperative that we replace the use of fossil fuels with renewable energy sources such as wind, solar, and hydroelectric. As these renewable energy sources are inherently intermittent, there exists a need for sustainable mechanisms to store renewable energy for later use. While the direct use of dihydrogen (H2) as a combustible fuel would allow for energy storage without the harmful release of carbon dioxide (CO2) upon combustion, the practicality of H2 as a synthetic fuel is limited by its low volumetric energy density. Combining sustainable H2 production (e.g. electrolysis using energy from renewable sources) with subsequent carbon fixation (e.g. the hydrogenation of CO2) represents a promising pathway to the sustainable production of high-density synthetic fuels. We hypothesize that such a process could be catalyzed by an IPr**-supported catalyst containing a hard/soft acid/base (HSAB) mismatch, with a polarizable coinage metal acting as a soft acid. As such, the aim of our project is the construction of a catalogue of IPr**-supported copper, silver, and gold catalysts that we anticipate will facilitate the heterolysis of dihydrogen and subsequent hydrogenation of CO2. In the present paper, we report the synthesis and characterization of an IPr**-silver complex which will serve as a precursor to many of our proposed HSAB mismatch catalysts and discuss next steps as we construct our catalogue of catalysts.
An AGN as a Counterpart for Neutrino Event IceCube-220303A

Creator: Nur Schettino
Access: Open access
- Cosmic rays have been detected for over a century. While some sources have been confirmed, they cannot explain the high energy of the particles (> 10^15 eV), so it remains unclear where and how they are accelerated to extreme energies. The study of astrophysical high-energy neutrinos may help solve the puzzle. These neutrinos are produced by cosmic rays interacting with other charged particles or photons. Moreover, while cosmic rays do not reveal their sources of origin because they can be deflected by magnetic fields, cosmic neutrinos detected by the IceCube Observatory can be traced back to their sources of origin. We will consider an active galactic nucleus (AGN) as a candidate source for a high-energy neutrino.This thesis examines the AGN WISEA J175051.31+105645.3 as a potential source for IceCube-220303A, a high-energy neutrino with a 78% probability of being astrophysical in origin. Using follow-up NuSTAR and Swift/XRT observations, WISEA J175051.31+105645.3 was the only viable source we found in IceCube-220303A’s uncertainty region. We used follow-up X-ray data to construct a multi-wavelength spectral energy distribution (SED) through which we calculated the AGN’s neutrino energy flux. This calculation yields the number of neutrinos we would expect to detect from the AGN in a given time period. We used this number to calculate the probability that IceCube-220303A was emitted by WISEA J175051.31+105645.3. Finding a statistically significant link between IceCube-220303A and WISEA J175051.31+105645.3 may help us better understand what processes can accelerate particles like cosmic rays to extreme energies and learn more about AGN.
