SUMMARY:Workshop / Seminar:EEB Student Dissertation Defense - Seeds of Change: The Power of Small-Scale Farming Communities
DESCRIPTION:Abstract:  Alexa critically examines the role of farm size in sustainable agriculture within the context of global food systems and political economies. She argues that small-scale farms are vital for sustainable development due to their unique capacity to implement eco-friendly practices and maintain local food sovereignty\, contrasting significantly with large-scale\, corporate farming models. The research utilizes a mix of qualitative and quantitative methods to explore how different farm sizes affect agricultural sustainability across diverse geographies\, including detailed case studies in Jamaica and Hawaii. By integrating theoretical frameworks with empirical research\, this study contributes to the discourse on sustainable agriculture and challenges existing policies that favor large-scale operations over smaller\, more sustainable farming practices.

SUMMARY:Workshop / Seminar:Differential Equations Seminar: Quantum Boltzmann dynamics around the Fermi ball
DESCRIPTION:In this talk\, we present new partial results on the derivation of quantum Boltzmann dynamics for a weakly interacting Fermi gas. We describe the time evolution of states that are perturbations of the Fermi ball\, and analyze the dynamics in particle-hole variables. Our main result states that\, for small values of the coupling constant and for appropriate initial data\, the effective dynamics of the momentum distribution is determined to leading order by a discrete collision operator of quantum Boltzmann form.

SUMMARY:Workshop / Seminar:Double Robustness of Local Projections and Some Unpleasant VARithmetic
DESCRIPTION:We consider impulse response inference in a locally misspecified vector autoregression (VAR) model. The conventional local projection (LP) confidence interval has correct coverage even when the misspecification is so large that it can be detected with probability approaching 1. This result follows from a “double robustness” property analogous to that of popular partially linear regression estimators. In contrast\, the conventional VAR confidence interval with short-to-moderate lag length can severely undercover\, even for misspecification that is small\, economically plausible\, and difficult to detect statistically. There is no free lunch: the VAR confidence interval has robust coverage only if the lag length is so large that the interval is as wide as the LP interval.

SUMMARY:Workshop / Seminar:Inventing the Tools to Unlock the Field of Microgravity Chemistry
DESCRIPTION:As chemists\, we instinctively manipulate variables – concentration\, temperature\, current – seeking the right conditions to achieve a desired outcome or retracing our steps to understand why certain inputs yield specific results. For all the billions of chemical experiments performed in human history\, gravity has been largely treated as a physical constant. But with rapidly growing access to space\, we now have the ability to treat gravity\, one of the four fundamental forces of nature\, as an experimental variable. Without gravity\, we have the opportunity to study how chemical reactions behave without the influence of acceleration-dependent convection\, hydrostatic pressure\, flotation\, sedimentation\, or container interactions. \n\nBut as with any new field of study\, the right tools are needed to understand and exercise its potential.   \n\nThe idea of experimentation in microgravity is not new – the first US space station\, Skylab (1973)\, hosted a series of chemistry experiments\, some as fundamental as “Metals Melting (M551)“. Many of these findings highlight the incredible potential microgravity environments offer for scientific discovery. However\, these experiments\, and those taking place on the International Space Station today\, are often performed in uncreative experimental setups and with equipment that was originally designed to operate on Earth. \n\nThis talk will outline previous investigations in microgravity\, note their findings and critique their experimental design\, and present Astral Materials’ approach to inventing the right tools for Microgravity Chemistry to reach its full potential.
