Broadband Equity, Access, And Deployment In Nevada, Brad Wimmer

Policy Briefs and Reports

The $45.45 billion Broadband, Equity, Access, and Deployment (BEAD) program’s primary objective is to extend broadband service to all unserved and underserved locations in the U.S. and its territories. Several industry studies predict that the BEAD program can meet its goal of providing universal access to broadband service if eligible entities execute their grant programs well. My review of the BEAD program indicates that policy makers can enhance the likelihood of program success by designing competitive grant programs that give applicants the incentive to undercut the subsidies proposed by their rivals and provide applicants the flexibility to design networks that …

Topology Identification In Distribution System Via Machine Learning Algorithms, Peyman Razmi, Mahdi Ghaemi Asl, Giorgio Canarella, Afsaneh Sadat Emami

Economics Faculty Publications

This paper contributes to the literature on topology identification (TI) in distribution networks and, in particular, on change detection in switching devices' status. The lack of measurements in distribution networks compared to transmission networks is a notable challenge. In this paper, we propose an approach to topology identification (TI) of distribution systems based on supervised machine learning (SML) algorithms. This methodology is capable of analyzing the feeder's voltage profile without requiring the utilization of sensors or any other extraneous measurement device. We show that machine learning algorithms can track the voltage profile's behavior in each feeder, detect the status of …

Impact Of Carb's Tailpipe Emission Standard Policy On Co2 Reduction Among The Us States, Jaewon Lim, Doohwan Won

Public Policy and Leadership Faculty Publications

U.S.Environmental Protection Agency (EPA) set the nationwide emission standard policy, but each state in the U.S. has an option to follow the higher emission standard policy set by CARB (California Air Resources Board) in 2004. There are 14 “CARB states” that follow California’s more restrictive standards. The purpose of this paper is to examine the impact of CARB’s tailpipe emission standard policy. Using the panel dataset for 49 U.S. states over a 28-year study period (1987–2015), this paper found the long-term policy effect in reducing CO2 emission from CARB’s tailpipe standard, and its long-run effect is 5.4 times higher than …

The Circulation Of Climate Change Denial Online: Rhetorical And Networking Strategies On Facebook, Emma Frances Bloomfield, Denise Tillery

Communication Studies Faculty Publications

This study uses a topical, rhetorical approach to analyze how climate change denial circulates online through the 25 most popular posts on the Watts Up With That and the Global Warming Policy Forum Facebook pages. These groups adopt the appearance of credibility through reposting and hyperlinking, thus establishing a supportive, networked space among other skeptical sites, while distancing readers from original sources of scientific information. Visitors use a variety of rhetorical strategies to echo posts’ main themes and to discredit alternative viewpoints. Differences between the topoi and rhetorical strategies of WUWT and the GWPF show that the climate change denial …

Elevation And Azimuth-Aided Channel Estimation Scheme For Airborne Hyperspectral Data Transmission, Vahid Vahidi, Ebrahim Saberinia

Electrical & Computer Engineering Faculty Research

A channel-estimation (CE) scheme is proposed to estimate the complex amplitude, Doppler shift, angle-of-departure, and angle-of-arrival of the channel taps for sparse and doubly selective channels for hyperspectral image transmission from unmanned aircraft vehicles (UAVs) to ground stations. The proposed method is dubbed as compressed-sensing joint parameter estimation (CS-JPE) and finds the channel parameters matrix by employing a compressed-sensing (CS)-based method. Afterward, a modified version of the joint parameter estimation (JPE) is proposed as CS-JPE and is dubbed as M-CS-JPE, which employs the elevation-azimuth angles of the line-of-sight channel tap to estimate the channel parameters with higher accuracy and lower …

Thing-Makers, Tool Freaks And Prototypers: How The Whole Earth Catalog’S Optimistic Message Reinvented The Environmental Movement In 1968, Andy Kirk

History Faculty Research

In the fall of 1968 a Stanford-trained biologist, organizer of the legendary Trips Festival and Merry Prankster named Stewart Brand published the first Whole Earth Catalog. Between 1968 and 1972, the Catalog reached millions of readers and won the National Book Award. The title and iconic cover image of this counterculture classic celebrated the first publicly released NASA photographs showing the whole planet Earth from space. These images profoundly changed the way humans thought about the environment. And the Catalog played an important role in that change.

Humans Thrived In South Africa Through The Toba Eruption About 74,000 Years Ago, Eugene I. Smith, Zenobia Jacobs, Racheal Johnsen, Minghua Ren, Erich C. Fisher, Simen Oestmo, Jayne Wilkins, Jacob A. Harris, Panagiotis Karkanas, Shelby Fitch, Amber Ciravolo, Deborah Keenan, Naomi Cleghorn, Christine S. Lane, Thalassa Matthews, Curtis W. Marean

Geoscience Faculty Research

Approximately 74 thousand years ago (ka), the Toba caldera erupted in Sumatra. Since the magnitude of this eruption was first established, its effects on climate, environment and humans have been debated1. Here we describe the discovery of microscopic glass shards characteristic of the Youngest Toba Tuff—ashfall from the Toba eruption—in two archaeological sites on the south coast of South Africa, a region in which there is evidence for early human behavioural complexity. An independently derived dating model supports a date of approximately 74 ka for the sediments containing the Youngest Toba Tuff glass shards. By defining the input of shards …

Rock Paper Scissors And Evolutionary Game Theory, Christian Cordova, Rudolf Jovero, Evan Thomas

Math 365 Class Projects

In Rock Paper Scissors (RPS), three different "species" compete, but no single species has a dominating strategy. In evolutionary game theory, replicator equations model population densities over time. When a mutation is introduced, they are called "replicator-mutator" equations. Using the replicator-mutator equation in [1] we have shown how population density of three species change.

Environment And Sustainability In Nevada, Jennifer Stevens, Genevieve Minter, Robert Futrell

Social Health of Nevada Reports

When the inaugural Earth Day launched the first environmental decade in the U.S. more than forty years ago, protecting our air, water, land and other natural resources seemed a relatively straightforward task. Environmental polluters and exploiters would be brought to heel by tough laws. The U.S. and other industrialized nations responded to quality of life concerns associated with environmental degradation by adopting dozens of major environmental and resource policies and creating new institutions such as the U.S. Environmental Protection Agency to manage environmental programs. Following these national developments, states and local communities began systematic efforts to address environmental problems.

Systems Of Access: A Multidisciplinary Strategy For Assessing The Social Dimensions Of Sustainability, Christopher Wolsko, Elizabeth Marino, Thomas J. Doherty, Steve Fisher, Amanda S. Green, Briana Goodwin, Ryan Reese, Andrea Wirth

Library Faculty Publications

The concept of access to natural resources has been a specific concern of economists and ecologists and is a distinct component in recent models of social sustainability. Using a series of conceptual and empirical examples, this article extends the notion of access broadly to social institutions and sociocultural norms. We argue that access may be usefully construed as an analytic tool that has direct applicability to many sustainability issues as it allows for cross-disciplinary and public engagement. Here the concept of access, linked to Amartya Sen’s theory of capabilities, also makes visible the multi-scaled and interconnected social processes that influence …

Religion, Partisanship, And Attitudes Toward Science Policy, Ted G. Jelen, Linda A. Lockett

Political Science Faculty Research

We examine issues involving science which have been contested in recent public debate. These “contested science” issues include human evolution, stem-cell research, and climate change. We find that few respondents evince consistently skeptical attitudes toward science issues, and that religious variables are generally strong predictors of attitudes toward individual issues. Furthermore, and contrary to analyses of elite discourse, partisan identification is not generally predictive of attitudes toward contested scientific issues.

Cracking The Code On Stem: A People Strategy For Nevada's Economy, Jessica A. Lee, Mark Muro, Jonathan Rothwell, Scott Andes, Siddharth Kulkarni

Brookings Mountain West Publications

Nevada has in place a plausible economic diversification strategy—and it’s beginning to work. Now, the state and its regions need to craft a people strategy. Specifically, the state needs to boost the number of Nevadans who possess at least some postsecondary training in the fields of science, technology, engineering, or math—the so-called “STEM” disciplines (to which some leaders add arts and design to make it “STEAM”).

The moment is urgent—and only heightened by the projected worker needs of Tesla Motors’ planned “gigafactory” for lithium-ion batteries in Storey County.

Even before the recent Tesla commitment, a number of the more high-tech …
