Modeling Acoustic Scattering From The Seabed Using Transport Theory, Jorge Quijano, Lisa M. Zurk
Modeling Acoustic Scattering From The Seabed Using Transport Theory, Jorge Quijano, Lisa M. Zurk
Electrical and Computer Engineering Faculty Publications and Presentations
Radiative Transfer (RT) theory has established itself as an important tool for electromagnetic remote sensing in parallel plane geometries with random distributions of scatterers, and most recently it has also been proposed as a model for the propagation of elastic waves in layered ocean sediments. In this work the capabilities of this model are illustrated, as the RT method is used to predict backscattering strength from laboratory models of random media. The RT model is characterized by its flexibility on accommodating scatterers in a broad variety of sizes, shapes, and acoustic contrast relative to the background media. Additionally, this formulation …

Robin Leichenko and Karen O‘Brien have proposed ―double exposure‖ as a conceptual framework to demonstrate how processes of globalization and global environmental change (GEC) redefine risk and encourage new, interrelated responses to social and ecological transitions (O‘Brien and Leichenko, 2000; Leichenko and O'Brien, 2008). In particular, the concept encourages researchers and policy makers to consider interplay between global climate change and globalization and how this is expressed unevenly across space. After reviewing the ways double exposure has been used in the literature, we consider four case studies to investigate the utility of the framework for analyzing and understanding climate change …
Food Delivery Footprint: Addressing Transportation, Packaging, And Waste In The Food Supply Chain, Madeleine E. Pullman, Robin Fenske, Wayne Wakeland
Food Delivery Footprint: Addressing Transportation, Packaging, And Waste In The Food Supply Chain, Madeleine E. Pullman, Robin Fenske, Wayne Wakeland

Transportation of food accounts for a significant fraction of the carbon dioxide emissions believed to be adversely impacting climate and the environment. And this impact is increasing as food supply chains become longer and more complex, and food packaging requirements lead to increased waste. Many organizations such as hospitals and upper level education are becoming increasingly concerned about sustainability. In this study, college, university, and hospital food purchasing behavior were assessed using interviews, surveys, and modeling to evaluate the environmental implications of decisions regarding food transportation and packaging. Current purchasing practices, corresponding transportation modes, packaging, recycling, and waste removal were …

The Hydrology for the Environment, Life and Policy (HELP) program, a cross-cutting component of the UNESCO International Hydrological Programme (IHP), has as its goal to facilitate dialogue among hydrologists, social and economic scientists, water resource managers, water lawyers, policy experts, and river basin stakeholder communities in setting a research agenda driven by local management and policy issues. HELP seeks to improve the benefits to society by applying the principals of integrated water-resources management to complex, interdisciplinary issues within catchments.
This Monograph is the culmination of a workshop held in 2010 in which the managers from the six North American basins …
Local And Traditional Knowledge And The Historical Ecology Of Pacific Herring In Alaska, Thomas F. Thornton, Madonna L. Moss, Virginia L. Butler, Jamie Hebert, Fritz Funk
Local And Traditional Knowledge And The Historical Ecology Of Pacific Herring In Alaska, Thomas F. Thornton, Madonna L. Moss, Virginia L. Butler, Jamie Hebert, Fritz Funk

The article focuses on the historical ecology of the Pacific herring, a marine food web resource, in the Gulf of Alaska. It states the hearing conducted by the Alaska Legislature's House special committee on fisheries on the status and management of herring in Southeast Alaska during which Tlingit fisherman Clarence Jackson of Kake notes the disappearance of herring in his lifetime. Information on herring ecology based from Native and non-Native individuals from Southeast communities and archaeological site reports reveal that non-Natives in Southeast Alaska have exploited herring with the development of a herring reduction plant. It underscores the need for …
Archaeological Evidence For Resilience Of Pacific Northwest Salmon Populations And The Socioecological System Over The Last ~7,500 Years, Sarah K. Campbell, Virginia L. Butler
Archaeological Evidence For Resilience Of Pacific Northwest Salmon Populations And The Socioecological System Over The Last ~7,500 Years, Sarah K. Campbell, Virginia L. Butler
Anthropology Faculty Publications and Presentations
Archaeological data on the long history of interaction between indigenous people and salmon have rarely been applied to conservation management. When joined with ethnohistoric records, archaeology provides an alternative conceptual view of the potential for sustainable harvests and can suggest possible social mechanisms for managing human behavior. Review of the ~7,500-year-long fish bone record from two subregions of the Pacific Northwest shows remarkable stability in salmon use. As major changes in the ecological and social system occurred over this lengthy period, persistence in the fishery is not due simply to a lack of perturbation, but rather indicates resilience in the …

Integrated stormwater management using green infrastructure shows promise in saving money and mitigating environmental impacts caused by urban development. Equally important are the potential community benefits, including better understanding of ecological systems, increased access to urban green spaces, safer and healthier neighborhoods, and informed residents that are equipped to take action to improve watershed health. As a partnership between the City of Portland Environmental Services, Portland State University, and residents of the Tabor to the River (T2R) neighborhood, we conducted a survey to understand the role of civic ecology in green infrastructure projects. The survey results indicate a high interest …
Genetically Engineering Crops For A Sustainable Agriculture, David E. Ervin, Rick Welsh
Genetically Engineering Crops For A Sustainable Agriculture, David E. Ervin, Rick Welsh
Economics Faculty Publications and Presentations
The article examines the role of genetically engineered (GE) crops in fostering a more sustainable agriculture. An overview of the National Academy of Sciences metal study of the impacts of GE crops on farm sustainability in the U.S. is given. The two types of GE crops are discussed, one which produces its own insecticide called insect resistant (IR) crops and the other is engineered to resist particular herbicides. An explanation for sustainable agriculture is also presented.

The article determines the factors that drive academic bioscience to better understand the role of genetically engineered (GE) crops in the sustainability of U.S. agriculture. Some challenges brought about by GE crops in the U.S. farm sustainability include tracking and controlling water pollution, protecting against herbicide resistance and nitrogen fixation. Professional norms are also considered as a great factor driving the academic bioscience.
