Reaching Into The Past For Future Resilience: Recovery Efforts In Maine Rivers And Coastal Waters, John Lichter, Ted Ames Jan 2012

Reaching Into The Past For Future Resilience: Recovery Efforts In Maine Rivers And Coastal Waters, John Lichter, Ted Ames

Maine Policy Review

John Lichter and Ted Ames discuss how analysis of environmental histories of human activities affecting Maine’s estuary, river, and coastal marine ecosystems can shed light on the role key fish species may play. Through Maine’s Sustainability Solutions Initiative, a group of researchers from Bowdoin, Bates, Univer­sity of Southern Maine, and Penobscot East Resource Center have teamed up to examine ecological recovery in the state’s waterways and coastal fisheries. Several river restoration efforts were already underway, and others are being planned as a direct result of this inter­disciplinary project.

Economic Development And Maine’S Sustainability Solutions Initiative, Caroline L. Noblet, Kathleen P. Bell, Charles Colgan, Mario Teisl Jan 2012

Economic Development And Maine’S Sustainability Solutions Initiative, Caroline L. Noblet, Kathleen P. Bell, Charles Colgan, Mario Teisl

Maine Policy Review

The authors discuss how Maine’s Sustainability Solu­tions Initiative (SSI) can contribute to economic devel­opment in the state. SSI research is covering five of the seven targeted technology areas identified in recent reports as being important for economic development in the state (forestry and agriculture, environmental, information, composites, marine and aquaculture). The authors note how the broad scope of research carried out through SSI provides opportunities to catalyze new commercial opportunities. As important, SSI is providing many students with a unique learn­ing environment that will prepare them for the new knowledge-based economy.

Student Perspective: Margaret Chase Smith Library 2011 Essay Contest:, Zoe Anderson, Ali Clift, Allaina Murphy Jan 2012

Student Perspective: Margaret Chase Smith Library 2011 Essay Contest:, Zoe Anderson, Ali Clift, Allaina Murphy

Maine Policy Review

Each year, the Margaret Chase Smith Library sponsors an essay contest for Maine high school seniors. The focus of the 2011 contest was environmen­tal protection. The essay prompt quoted a 1972 statement from Sen. Smith: “We must recognize that we’re not going to eliminate pollution overnight. It’s going to be a hard, long fight. It’s going to take a long time and a lot of sacrifice on the part of each one of us.” By happy coinci­dence, the essay contest topic fits perfectly with the subject matter of this special issue of Maine Policy Review on sustainability. We feature here …

Attitudes Toward Offshore Wind Power In The Midcoast Region Of Maine, James Acheson Jan 2012

Attitudes Toward Offshore Wind Power In The Midcoast Region Of Maine, James Acheson

Maine Policy Review

Given the likelihood of the development of offshore wind farms in Maine and the increasingly politicized nature of discussions about wind power in general, there is a need for more systematic information on Mainers’ opinions about offshore wind power. In this article, James Acheson provides information on the range of public opinion about offshore wind power based on a survey of fishermen, tourism-related business owners and coastal property owners in Midcoast Maine. He assesses the accuracy of some public concerns and discusses the broader policy issues raised about offshore wind development.

The Path To Sustainable Water Resources Solutions, John Peckenham, David Hart, Sean Smith, Shaleen Jain, Whitney King Jan 2012

The Path To Sustainable Water Resources Solutions, John Peckenham, David Hart, Sean Smith, Shaleen Jain, Whitney King

Maine Policy Review

Water is essential both to human survival and to the ecosystems on which people depend. Although Maine is blessed with abundant water sources, managing them is crucial for both short and long-term uses. The authors describe the varying time and spatial scales involved in managing water resources, pointing out that policy decisions made at one time can have far-reaching consequences. They provide illustrations of water-resource projects from Maine’s Sustainability Solutions Initiative, ranging in size from Sebago Laketo vernal pools on individual properties.

Wicked Tools: The Value Of Scientific Models For Solving Maine’S Wicked Problems, Tim Waring Jan 2012

Wicked Tools: The Value Of Scientific Models For Solving Maine’S Wicked Problems, Tim Waring

Maine Policy Review

“Wicked problems” are urgent, high-stake socioeconomic-environmental challenges that often involve ideological conflict and have no “best solutions.” Using examples from Maine’s Sustainability Solutions Initiative projects, Tim Waring describes how scientific models can be used to address these kinds of problems. When well-constructed and tested models are used to address policy-relevant issues, include input from stakeholders, and integrate social, economic and environmental dynamics, they can become “wicked tools” to address some of society’s biggest challenges.

Secrecy Logic: S-Secrecy Structures, George Voutsadakis Jan 2012

Secrecy Logic: S-Secrecy Structures, George Voutsadakis

Turkish Journal of Mathematics

Let S = \lan L,\vdash_S\ran be a deductive system. An S-secrecy logic is a quadruple K = \lan Fm_L(V),K,B,S\ran, where Fm_L(V) is the algebra of L-formulas, K,B are S-theories, with B \subseteq K and S \subseteq K such that S \cap B = \emptyset. K corresponds to information deducible from a knowledge base, B to information deducible from the publicly accessible (or browsable) part of the knowledge base and S is a secret set, a set of sensitive or private information that the knowledge base aims at concealing from its users. To provide models for this context, the notion of …

On Cosets In Coxeter Groups, Sarah B. Hart, Peter J. Rowley Jan 2012

On Cosets In Coxeter Groups, Sarah B. Hart, Peter J. Rowley

Turkish Journal of Mathematics

In this paper the notion of Coxeter length for a subset of a Coxeter group, as introduced in [9], is investigated for various subsets of a Coxeter group. Mostly cosets of various subgroups are examined as well as the associated idea of X-posets, which is a vast generalization of the Bruhat order.
