Source-Receptor Relationships for Ozone and Fine Particulates in the Eastern United States
Get PDFA key question in developing effective mitigation strategies for ozone and particulate matter is identifying which source regions contribute to concentrations in receptor regions. Using a direct approach with a regional, multiscale three-dimensional model, we derive multiple source-receptor matrices (S-Rs) to show inter- and intrastate impacts of emissions on both ozone and PM2.5 over the eastern United States. Our results show that local (in-state) emissions generally account for about 23% of both local ozone concentrations and PM2.5 concentrations, while neighboring states contribute much of the rest. The relative impact of each state on others varies dramatically between episodes. In reducing fine particulate concentrations, we find that reducing SO2 emissions can be 10 times as effective as reducing NOx emissions. SO2 reductions can lead to some increase in nitrates, but this is relatively small. NOx reductions, however, lead to both ozone reductions and some reduction in nitrate and sulfate particulate matter.source-receptor, ozone, particulate matter, sensitivity analysis, air quality simulation, National Ambient Air Quality Standards

No full textControlling Ozone and Fine Particulates: Cost Benefit Analysis with Meteorological Variability
Get PDFIn this paper, we develop an integrated cost-benefit analysis framework for ozone and fine particulate control, accounting for variability and uncertainty. The framework includes air quality simulation, sensitivity analysis, stochastic multi-objective air quality management, and stochastic cost-benefit analysis. This paper has two major contributions. The first is the development of stochastic source-receptor (S-R) coefficient matrices for ozone and fine particulate matter using an advanced air quality simulation model (URM-1ATM) and an efficient sensitivity algorithm (DDM-3D). The second is a demonstration of this framework for alternative ozone and PM2.5 reduction policies. Alternative objectives of the stochastic air quality management model include optimization of the net social benefits and maximization of the reliability of satisfying certain air quality goals. We also examine the effect of accounting for distributional concerns.ambient air, ozone, particulate matter, risk management, public policy, cost-benefit analysis, variability and uncertainty, stochastic simulation, stochastic multi-objective programming, decisionmaking, National Ambient Air Quality Standards
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

Effects of Carbon Policies and Technology Change
Get PDFWe develop and estimate an index-based measure of expected consumer welfare under various carbon emissions control policies in the electricity generation sector. This approach estimates welfare effects by a somewhat less data intensive methodology than econometric approaches or more complex modeling. We include anticipated technological change in the production of renewable and nonrenewable power generation during the next two decades. We estimate welfare improvements from 2000 to 2020 as renewable energy technologies continue to be improved and gradually adopted, compared with a counterfactual scenario allowing for continual improvement of nonrenewable generation technology. We formally incorporate uncertainty. We evaluate the model under alternative carbon emissions control policies, including policies that create incentives through price mechanisms and policies that mandate the composition of the generation portfolio. We focus on three countries that differ widely in their power fuel mix: India, Germany, and the United States.carbon emissions control, electricity generation, technological change, consumer welfare

Author-Illustrator
No full textThis essay investigates the concept author-illustrator by drawing on two influential essays – ‘Death of the Author’ by Roland Barthes and ‘What is an Author?’ by Michel Foucault. By engaging with the key points of debate that emerge from these positions, this essay argues that the notion of author-illustrator is part of a wider discursive field that is embedded in a complex, commodified, multimedia public sphere where the author is paradoxically reinscribed and erased. This environment is changing the nature of the text, authorship, and reader-text interaction, but until now the concept author-illustrator has been largely absent from these discussions
