NRDC Sues EPA for a Failure to Issue Hazardous Substance Regulations: The End of a Decades-Long Public Risk in Sight
Currently there are no federal regulations that prevent hazardous substance spills at onshore facilities, such as tank farms, or in communities where a spill of those chemicals could threaten water supplies. On July 21, 2015, the Natural Resources Defense Council (NRDC) filed a complaint on behalf of the Environmental Justice Health Alliance for Chemical Policy Reform (EJHA) and People Concerned About Chemical Safety (PCCS) against EPA and EPA Administrator Gina McCarthy in her official capacity as administrator, in the U.S. District Court for the Southern District of New York. The case has been assigned to Judge Shira A. Sheindlin. The complaint alleges EPA is in violation of section 311(j)(1)(C) of the Clean Water Act (CWA)
Preferences for Exposure Control of Power-Frequency Fields among Lay Opinion Leaders
The authors report on surveys, differing according to focus on remedial costs, of Pittsburgh-area adults indicating beliefs about possible health effects of electromagnetic fields and the acceptability of options for reducing or eliminating the potential impact
A Survey of Organizational Plans for the Instruction of Reading with Specific Guidelines for Revision of the Program at Phantom Lake Elementary
The purpose of this study is to review the past and present reading programs at Phantom Lake Elementary School, Bellevue, Washington, and to recommend guidelines by which the existing program can be improved. These guidelines will be based on a review of the literature
The structure sheaf of the moduli of oriented -divisible groups
Using spectral algebraic geometry, we define a derived moduli stack of
oriented -divisible groups and study its structure sheaf. This stack is
consequently used to prove a theorem of Lurie which predicts the existence of a
certain sheaf of -rings
on a formally \'{e}tale site of
the classical moduli stack of -divisible groups. A variety of sections of
this sheaf are then shown to be equivalent to known -rings
in stable homotopy theory, and the natural symmetries on these sections also
recover well-studied actions and operations.Comment: 82 pages, comments always welcom
Elliptic cohomology is unique up to homotopy
Homotopy theory folklore tells us that the sheaf defining the cohomology
theory Tmf of topological modular forms is unique up to homotopy. Here we
provide a proof of this fact, although we claim no originality for the
statement. This retroactively reconciles all previous constructions of Tmf.Comment: 18 pages, comments are very welcom
Comparing tempered and equivariant elliptic cohomology
Lurie and Gepner--Meier each define equivariant cohomology theories, namely
"tempered cohomology" and "equivariant elliptic cohomology," respectively,
using derived algebraic geometry. We construct a natural equivalence between
the equivariant elliptic cohomology of a preoriented abelian variety
and the tempered cohomology of the associated preoriented
-divisible group . Moreover, we
emphasise the naturality and coherence of both these equivariant theories as
well as our comparison. To demonstrate the use of this comparison, we show that
equivariant topological modular forms is
dualisable as a -module for all compact Lie groups which
decompose as a product of a torus and a finite group by formally reducing to an
argument of Gepner--Meier.Comment: 18 pages, comments welcom
Forecasting the Outcome of NFL Playoff Games: A Regression Analysis
Professional sports are one of the most consumed forms of entertainment in the world today. Professional sporting events are some of the most watched broadcasts worldwide each year. The 2022 FIFA World Cup Final garnered about 1.5 billion views worldwide, almost 20% of our planet’s population (Jones, 2023). The National Football League is the most popular professional sport in the United States. Recent polling data shows that a clear majority of the country, 72% of Americans, self-identify as football fans (“St. Bonaventure”, 2023). The NFL runs from September to February and regularly draws 15-20 million viewers weekly during the regular season, which lasts 18 weeks. The regular season is followed by the playoffs, which last five weeks and draw more viewers than any regular season games. The playoffs culminate in the most watched single broadcast in the United States each year: the Super Bowl (Stoll, 2024). This project took a data-based statistical approach to predicting the outcome of NFL playoff games using historical performance data combined with modern-day statistical modeling techniques. Specifically, this project used a stepwise variable selection approach to determine statistically significant predictors and integrate them into a multiple linear regression model to predict the final score of NFL playoff games. This project’s final regression model predicted the correct winner of NFL playoff games 64.41% of the time and the correct winner against the spread 56.78% of the time over the past ten years
