Interview With Robert Kates, Pathfinder In Sustainability Science, Bridie Mcgreavy, Robert Kates
Maine Policy Review
In this interview, Robert Kates discusses the challenges of sustainability science in moving from what scientists know to actions that can provide solutions to pressing environmental and development problems. Kates notes that sustainability science has the dual mission of addressing core scientific and intellectual questions, while at the same time addressing development in particular places. He suggests that one of the key questions is how to address long-term trends and transition to a “better synthesis between environment and society.”
Advancing Science And Improving Quality Of Place: Linking Knowledge With Action In Maine’S Sustainability Solutions Initiative, Damon Hall, Linda Silka, Laura Lindenfeld
Advancing Science And Improving Quality Of Place: Linking Knowledge With Action In Maine’S Sustainability Solutions Initiative, Damon Hall, Linda Silka, Laura Lindenfeld
Maine Policy Review
The authors give an overview of how research carried out through Maine’s Sustainabilty Solutions Initiative (SSI) improves traditional models of science by providing a fuller picture of the interaction between social and ecological systems. They provide examples of university-community research partnerships, where there is a continuous communication and feedback process that identifies problems and develops projects with a solutions-oriented focus. SSI projects, they argue, “focus on issues that may make lasting improvements to Maine’s quality of place.”
Wicked Tools: The Value Of Scientific Models For Solving Maine’S Wicked Problems, Tim Waring
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.

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.

Place-Based Approaches To Alternative Energy: The Potential For Forest And Grass Biomass For Aroostook County, Jason Johnston, Soraya Cardenas
Maine Policy Review
Teams at the University of Maine Presque Isle and the University of Maine at Forth Kent are engaged in evaluating the potential for forest and grass biomass energy in Aroostook County, funded through Maine’s Sustainability Solutions Initiative. The article discusses how this potential is being evaluated and the possible ways in which expanding grass and wood biomass might benefit farmers and residents of The County. It suggests that using some of Maine’s farmland for fuel might be sustainable with appropriate management and with consideration for potential environmental and socioeconomic drawbacks
Healthy Lakes And Vibrant Economies: Linking History, Sense Of Place, And Watershed Protection In The Belgrade Lakes Region, James Rodger Fleming, Erin A. Love
Healthy Lakes And Vibrant Economies: Linking History, Sense Of Place, And Watershed Protection In The Belgrade Lakes Region, James Rodger Fleming, Erin A. Love
Maine Policy Review
Using interviews, targeted questionnaires, and historical documents, James Fleming and Erin Love show how history and “sense of place” can help encourage individuals to support environmental protection. The project they describe focuses on watershed protection in the Belgrade Lakes region of Maine, and is part of a larger Sustainability Solutions Initiative project in that region. They argue that “connection to place leads to caring about it.”
Reaching Into The Past For Future Resilience: Recovery Efforts In Maine Rivers And Coastal Waters, John Lichter, Ted Ames
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.
Sustainability And Workforce Development In Maine, Catherine S. Renault, Linda Silka, James (Jake) S. Ward
Sustainability And Workforce Development In Maine, Catherine S. Renault, Linda Silka, James (Jake) S. Ward
Maine Policy Review
Maine is facing challenges in terms of its workforce: education levels lag behind those in the other New England states; population growth is slow; and the economy is undergoing a change that has shifted from manufacturing to more knowledge-based jobs. Catherine Renault, Linda Silka and Jake Ward discuss these challenges, looking at what employers want in their employees and at the kinds of jobs the state is likely to see in the future. They point out that the Sustainability Solutions Initiative, with its emphasis on a boundary-crossing approach to education, is an example of a way to train today’s students …
Economic Development And Maine’S Sustainability Solutions Initiative, Caroline L. Noblet, Kathleen P. Bell, Charles Colgan, Mario Teisl
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
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
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.
Biofuels Development In Maine: Using Trees To Oil The Wheels Of Sustainabilty, Caroline L. Noblet, Mario F. Teisl, Katherine H. Farrow, Jonathan Rubin
Biofuels Development In Maine: Using Trees To Oil The Wheels Of Sustainabilty, Caroline L. Noblet, Mario F. Teisl, Katherine H. Farrow, Jonathan Rubin
Maine Policy Review
As national standards require increased use of renewable transportation fuels by 2022, Maine is positioned to be a leader in wood-based cellulosic ethanol production and use. Caroline Noblet, Mario Teisl, Katherine Farrow, and Jonathan Rubin consider Mainers’ willingness to accept and use biofuels. They document the current level of consumer knowledge and behavior and identify factors (environmental, economic, and energy security) that may assist or constrain drivers from purchasing biofuels.
Colonel Blotto Games And Lancaster's Equations: A Novel Military Modeling Combination, Andrew Collins, Patrick T. Hester
Colonel Blotto Games And Lancaster's Equations: A Novel Military Modeling Combination, Andrew Collins, Patrick T. Hester
VMASC Publications
Military strategists face a difficult task when engaged in a battle against an adversarial force. They have to predict both what tactics their opponent will employ and the outcomes of any resultant conflicts in order to make the best decision about their actions. Game theory has been the dominant technique used by analysts to investigate the possible actions that an enemy will employ. Traditional game theory can be augmented by use of Lanchester equations, a set of differential equations used to determine the outcome of a conflict. This paper demonstrates a novel combination of game theory and Lanchester equations using …
Using Agent-Based Modeling To Simulate The Foreclosure Contagion Effect, Andrew J. Collins, Michael J. Seiler
Using Agent-Based Modeling To Simulate The Foreclosure Contagion Effect, Andrew J. Collins, Michael J. Seiler
Engineering Management & Systems Engineering Faculty Publications
A foreclosed property can have a negative impact on the prices of other properties within its neighborhood and these reduced property prices can lead to further foreclosures within the neighborhood; this is known as the foreclosure contagion effect. This effect has been demonstrated, within the real estate literature, to occur. Traditionally, real estate research have used statistical regression to analysis this issues. The application of Agent-based Modeling and Simulation (ABMS) has risen in the last 15 years and has successfully been used to model complexity situations, e.g., the real estate market. ABMS offers a way to explore the impact of …
Simulation Visualization Rhetoric And It's Practical Implications, D'An Knowles Ball, Andrew J. Collins
Simulation Visualization Rhetoric And It's Practical Implications, D'An Knowles Ball, Andrew J. Collins
Engineering Management & Systems Engineering Faculty Publications
Modeling and simulation has moved far beyond simple data representation into the world of visual communication over the past 15 years; ultimately, the acceptance of M&S within mainstream science and society will depend on the results that are produced visually. A simulation’s function is of primary importance to its end result, but it cannot be denied that the discipline of M&S now prizes fancy graphics to communicate. Rhetorical methodological decisions have the greatest impact on the end user, and considerations that bring visual rhetoric to modeling and simulation should be examined as a necessity to application. This paper will expose …

We present the design and performance of the LIGO Input Optics subsystem as implemented for the sixth science run of the LIGO interferometers. The Initial LIGO Input Optics experienced thermal side effects when operating with 7 W input power. We designed, built, and implemented improved versions of the Input Optics for Enhanced LIGO, an incremental upgrade to the Initial LIGO interferometers, designed to run with 30 W input power. At four times the power of Initial LIGO, the Enhanced LIGO Input Optics demonstrated improved performance including better optical isolation, less thermal drift, minimal thermal lensing, and higher optical efficiency. The …

On The Synthesis And Physical Properties Of Iron Doped Sno2 Nanoparticles, X. Wei, R. Georgescu, N. Ali, I. Morjan, T. A. George, F. Dumitrache, R. Birjega, Mircea Chipara
Physics and Astronomy Faculty Publications and Presentations
The synthesis of iron doped tin oxide by pulsed laser pyrolysis is reported. The as obtained nanoparticles have a dominant SnO2 phase (as revealed by Wide Angle X-ray Scattering), with particles of the order of 10 nm. The doping with iron or iron oxide triggers magnetic properties as confirmed by SQUID experiments. EDX measurements supported the presence of Fe while Wide Angle X-ray Scattering failed to sense any iron or iron-oxide phase. It is concluded that Fe is well dispersed within the tin-oxide nanoparticles. The coercitive field has a complex dependence on the Fe/Sn content suggesting that the magnetization is …

2.1Μm Emission Spectral Properties Of Tm And Ho Doped Transparent Yag Ceramic, G. A. Kumar, Madhab Pokhrel
Physics and Astronomy Faculty Publications and Presentations
Highly transparent Tm:Ho:YAG transparent ceramics were prepared using advanced ceramic technology and their spectroscopic properties were studied for infrared laser applications. Following the Judd-Ofelt procedure several spectroscopic properties such as the radiative transition probability (Arad), radiative decay time (τrad) and fluorescence branching ratio (β) are quantitatively obtained from the absorption spectrum. The absorption and emission cross sections corresponding to the 5I7 → 5I8 transition of Ho3+ at 2.1 μm have been evaluated following Mc Cumber theory and found that the obtained emission spectrum very well correlates to the simulated emission spectral data. The optical gain spectrum spread …
The Association Of Summer Temperatures With Hospital Admissions For Renal Diseases In New York State : A Case-Crossover Study, Barbara A. Fletcher
The Association Of Summer Temperatures With Hospital Admissions For Renal Diseases In New York State : A Case-Crossover Study, Barbara A. Fletcher
Legacy Theses & Dissertations (2009 - 2024)
This study assessed the association between high temperatures and increased odds of hospitalization for renal diseases which, to date, has been examined in only a small number of studies. A case-crossover design was used to study 147,885 hospital admissions with renal diagnoses during July and August, 1991-2004 in New York State. Regional temperature, humidity and barometric pressure data from automated monitors were used as exposure indicators. Using time-stratified referent selection and conditional logistic regression analysis, an overall 9% increase in odds of hospitalization for acute renal failure per 5°F (2.78°C) was found for mean temperature at a one day lag …

Dissolved organic matter (DOM) was extracted by solid-phase extraction (SPE) from 137 water samples from different climate zones and different depths along an eastern Atlantic Ocean transect. The extracts were analyzed with Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) with electrospray ionization (ESI). Δ14C analyses were performed on subsamples of the SPE-DOM. In addition, the amount of dissolved organic carbon was determined for all water and SPE-DOM samples as well as the yield of amino sugars for selected samples. Linear correlations were observed between the magnitudes of 43 % of the FT-ICR mass peaks and the extract Δ14C …

The Legendre Transform Of The Holst Action, Caixia Gao
The Legendre Transform Of The Holst Action, Caixia Gao
Electronic Theses and Dissertations
I start with a short introduction on 3+1 ADM form and the tetrad form of General Relativity, then I review the Legendre transform of the Einstein-Hilbert action and the Palatini action. The Holst action is a generalization of the Palatini action by including a topological term. I derive Ashtekar's connection form directly from this action by doing the Legendre transformation rather than by a canonical transformation in the usual phase space. This is done in both Remmanian signature with half-flat connection and Lorentz signature with general Barbero-Immirzi parameter.
Contributions To Robust Methods: Modified Rank Covariance Matrix And Spatial-Em Algorithm, Kai Yu
Contributions To Robust Methods: Modified Rank Covariance Matrix And Spatial-Em Algorithm, Kai Yu
Electronic Theses and Dissertations
Classical multivariate statistical inference methods including multivariate analysis of variance, principal component analysis, factor analysis, canonical correlation analysis are based on sample covariance matrix. Those moment-based techniques are optimal (most efficient) under the normality distributional assumption. They are, however, extremely sensitive to outlying observations, susceptible to small perturbation in data and poor in the efficiency for heavy-tailed distributions. A straightforward treatment is to replace the sample covariance matrix with a robust one. Visuri et al. (2000) proposed a technique for robust covariance matrix estimation based on different notions of multivariate sign and rank. Among them, the spatial rank based covariance …
On K-Trees And Special Classes Of K-Trees, John Wheless Estes
On K-Trees And Special Classes Of K-Trees, John Wheless Estes
Electronic Theses and Dissertations
The class of k-trees is defined recursively as follows: the smallest k-tree is the k-clique. If G is a graph obtained by attaching a vertex v to a k-clique in a k-tree, then G is also a k-tree. Trees, connected acyclic graphs, are k-trees for k = 1. We introduce a new parameter known as the shell of a k-tree, and from the shell special subclasses of k-trees, tree-like k-trees, are classified. Tree-like k-trees are generalizations of paths, maximal outerplanar graphs, and chordal planar graphs with toughness exceeding one. Let fs = fs( G) be the number of independent sets …

Multi-Configurational Investigation Of Thermolytic Pathways Of Highly Strained Ring Systems, Jeffrey Dwayne Veals
Electronic Theses and Dissertations
The isomerization pathways of model high energy structures are of interest because of their relation to high energy density fuels. Electron resonance has been found to greatly affect the relative activation barriers for several isomerization pathways, and the major goal of this research is to accurately describe its role in determining the relative barriers for strain energy release pathways. This research is centered around the potential energy surfaces (PES's) for ? bond breaking and ? bond rotation in these highly strained structures. Of particular interest was how would resonance and or electronegativity affect the allowed/disallonature of the activation barriers in …
