The Politics And Culture Of Climate Change: Us Actors And Global Implications, Charles Waugh Jan 2011

The Politics And Culture Of Climate Change: Us Actors And Global Implications, Charles Waugh

English Faculty Publications

Despite the scientific consensus on global warming, many people in the USA,—both ordinary citizens and elected leaders alike—remain skeptical of the need to act, and in fact remain skeptical of the idea that humans are contributing to global warming at all. Thus, environmental justice arguments based on United States carbon emissions and the disproportionate impact of rising temperatures and rising sea levels on tropical developing nations such as Vietnam frequently fall on deaf ears. This chapter explores the political and cultural construction of this deafness, seeking a better understanding of how and why so many Americans refuse to act to …

Linkages To Public Land Framework: Toward Embedding Humans In Ecosystem Analyses By Using “Inside-Out Social Assessment", Joanna Endter-Wada, D. J. Blahna Jan 2011

Linkages To Public Land Framework: Toward Embedding Humans In Ecosystem Analyses By Using “Inside-Out Social Assessment", Joanna Endter-Wada, D. J. Blahna

Environment and Society Faculty Publications

This article presents the ‘‘Linkages to Public Land’’ (LPL) Framework, a general but comprehensive data-gathering and analysis approach aimed at informing citizen and agency decision making about the social environment of public land. This social assessment and planning approach identifies and categorizes various types of linkages that people have to public land and guides the tasks of finding and using information on people in those linkages. Linkages are defined as the ‘‘coupling mechanisms’’ that explain how and why humans interact with ecosystems, while linkage analyses are empirical investigations contextualized both temporally and geographically. The conceptual, legal, and theoretical underpinnings of …

Development And Implementation Of A Bayesian Model For Sediment Transport In Fluvial Systems, Mark Schmelter Jan 2011

Development And Implementation Of A Bayesian Model For Sediment Transport In Fluvial Systems, Mark Schmelter

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Recent studies in the field of fluvial sediment transport underscore the difficulty in reliably estimating transport model parameters, collecting accurate observations, and making predictions due to measurement error and conceptual model uncertainty. There is a pressing need to develop models that can account for measurement error, conceptual model uncertainty, and natural variability while providing probability-based predictions as well as a means for conceptual model discrimination. The model presented in this research employs an excess shear sediment transport equation for a uni-size sediment bed developed in a Bayesian statistical framework. This statistical model provides a means to rigorously estimate distributions of …

Surface Geometry And Heat Flux Effects Onnucleate Pool Boiling Of Subcooled Water In Microgravity, Troy Munro, Andrew Fassman, Heng Ban, John R. Dennison Jan 2011

Surface Geometry And Heat Flux Effects Onnucleate Pool Boiling Of Subcooled Water In Microgravity, Troy Munro, Andrew Fassman, Heng Ban, John R. Dennison

All Physics Faculty Publications

The motivation of this nucleate boiling research is to understand the effects of surface geometry and heat flux as applied to a thin wire heater. This will further the understanding of the fundamental behaviors of boiling onset, steady state heat transfer, and bubble dynamics with respect to nucleate boiling with the goal of creating efficient thermal management systems for future space applications. Using three different thin platinum wire geometries and five different power levels, subcooled water was boiled over a period of approximately 30 seconds for 15 parabolic arcs to simulate microgravity. To represent the trends in bubbles behavior across …

Space Weather Community Operations Workshop: Planning For The Next Decade, J. J. Fulgham, Jennifer L. Meehan, W. K. Tobiska Jan 2011

Scenario: Japan suffers a great earthquake, a major tsunami, and a catastrophic nuclear meltdown. Telecommunications landlines and cell phone towers are inoperable in northern prefectures. This means that high-frequency (HF) radio becomes the primary means of communication to some affected areas. This also means that 3-hour forecasts of HF availability must be provided by space weather service organizations not affected by the disaster (Figure 1). Questions: How accurate are the HF predictions? How reliable is the service? How available is the information?
