REPRESENTING POLLUTION AT THE AGRARIAN–URBAN FRONTIER: Participatory Documentary Film‐Making in Bar Elias, Lebanon

open access: yesInternational Journal of Urban and Regional Research, EarlyView.
Abstract The Beqaa Valley in Lebanon has become increasingly polluted, and residents are attributing illness to improper waste disposal and dumping. This article explores local epistemologies of pollution’s causes and effects in three films, which were researched and produced by local residents of Bar Elias, a small town in the Beqaa, which has rapidly

Simulation Model of Pumped Hydroelectric Power Plant

open access: yesActa Electrotechnica et Informatica, 2015
Abstract The Pumped hydroelectric power plants are very suitable way to avoid the unpredictable imbalance in power generation, but its construction is very expensive and reliability is very long-term. Every single pumped hydroelectric power plant is like rechargeable battery which can generate electricity when there is a deficiency in power generation ...

GOVERNING THE CLOUD: Infrastructural Statecraft and the Political Ecology of Digital Expansion in Oregon

open access: yesInternational Journal of Urban and Regional Research, EarlyView.
Abstract Oregon's wave of data center and semiconductor projects shows how cloud capitalism reorganizes resource systems and territorial governance. Examining Amazon, Google, and Intel, the article traces how fiscal incentives, utility programs, and land‐use instruments are recalibrated to secure hyperscale loads.

Storage games

open access: yesThe RAND Journal of Economics, EarlyView.
ABSTRACT We study a long‐horizon, oligopolistic market with random shocks to demand that can be arbitraged by two storage operators with finite capacity. This problem applies to any storable commodity—that is, most commodities. Because the arbitrage spread is so sensitive to market power, storage operators face strong incentives to restrain quantities ...

Demonstration of an instream flow model to accommodate a threatened tiger beetle in riverine dune habitat

open access: yesInsect Conservation and Diversity, EarlyView.
Burrows of the threatened Gibson's Big Sand Tiger Beetle in riverine dune habitats are susceptible to flooding through managed flows. HEC‐RAS modelling identified the flow thresholds above which flooding would occur for burrows and affect the beetle larvae. These findings provide instream flow guidelines for conserving this threatened species and guide
