Prototype Automated Flow-Through Sensor For Measuring Waterborne Microbial Concentrations Using Bulk Fluorescence, Susan M. Savill
Prototype Automated Flow-Through Sensor For Measuring Waterborne Microbial Concentrations Using Bulk Fluorescence, Susan M. Savill
Graduate Masters Theses
Timely and inexpensive monitoring of microbial ecology in the world's water supplies is crucial to the study of environmental and human impact on water quality and the prevention of disease outbreaks. Current technology is lacking in its ability to accurately measure and predict the presence of possible disease pathogens in a timely and cost effective manner. This paper describes the construction and initial testing of an automated prototype water sensor intended to detect fluctuations in microbial density in real-time by using bulk fluorescence of SYBR Gold stained bacteria. The sensor is comprised of off-the-shelf hardware and an in-house designed and …
Brief 2: Overcoming Fragmented Governance: The Case Of Climate Change And The Mdgs, Oran R. Young
Brief 2: Overcoming Fragmented Governance: The Case Of Climate Change And The Mdgs, Oran R. Young
Governance and Sustainability Issue Brief Series
Fragmented governance hampers efforts to address tightly coupled challenges, like coming to grips with climate change and fulfilling the Millennium Development Goals. The way forward is to launch programmatic initiatives focusing on adaptation to climate change and the transition to a green economy that appeal to many separate bodies as win-win opportunities.

Brief 1: Financing International Environmental Governance: Lessons From The United Nations Environment Programme, Maria Ivanova
Governance and Sustainability Issue Brief Series
Financing for the global environment is scattered among many institutions and, without an overview of total financial flows, often considered scarce. This issue brief begins an analysis of the financial landscape by focusing on the anchor institution for the global environment, the UN Environment Programme. It examines the relationship between institutional form and funding and offers insights into innovative financing.
The Implications Of Water Insecurity For Fragile And Failing States: The Case Of Pakistan, Jennifer Norins
The Implications Of Water Insecurity For Fragile And Failing States: The Case Of Pakistan, Jennifer Norins
Graduate Masters Theses
As we become more firmly established in the 21st century, the international system faces a number of increasingly more difficult challenges that pose threats to global security and human progress. Among these challenges, water scarcity and failing states have each received prominent attention in both the academic and policy realms. Water serves a number of critical purposes for human survival and socio-economic activity. The threat of water scarcity is becoming increasingly salient and the capacity of states to ensure water security, and other securities which water security supports, is being tested. Fragile and failing states also occupy significant space in …
The Conservation And Habitat Ecology Of Antillean Manatees (Trichechus Manatus Manatus) In The Drowned Cayes Area Of Belize, Central America, Katherine Spencer Lacommare
The Conservation And Habitat Ecology Of Antillean Manatees (Trichechus Manatus Manatus) In The Drowned Cayes Area Of Belize, Central America, Katherine Spencer Lacommare
Graduate Doctoral Dissertations
The Drowned Cayes area of Belize, Central America is regionally important for the conservation of Antillean manatees in the Caribbean (Lefebvre et al. 2001; Quintana-Rizzo & Reynolds 2008). These islands are increasingly threatened by human activities such as tourism, development and population growth. The objective of this dissertation is to evaluate manatee habitat use and status in this area. The 5 specific objectives are to examine manatee (1) distribution in the Drowned Cayes, (2) use of seagrass beds and forage selection, (3) resting habitat use and selection (4) response to disturbance, and (5) trends in abundance and to suggest a …
A Model For Relating Environmental Variation To Water Permit Violations At Thermoelectric Facilities, Seth Sheldon
A Model For Relating Environmental Variation To Water Permit Violations At Thermoelectric Facilities, Seth Sheldon
Interdisciplinary Perspectives: a Graduate Student Research Showcase
A regression model is presented which relates cooling water withdrawal rates and discharge temperatures at two mid-size thermoelectric facilities to electricity demand and ambient air temperature using historical data. Both facilities employ open-loop cooling systems, which have substantial water demands. Open-loop facilities comprise roughly one third of U.S. generation capacity. High water demands put facilities and downstream aquatic habitats at risk during heat waves and droughts, and put facility managers in a position to decide between reducing their power generation and violating their permit limits. National Pollutant Discharge Elimination System (NPDES) permits place limits on cooling water withdrawals and effluent …
Super-Aggregations Of Krill And Humpback Whales In Wilhelmina Bay, Antarctic Peninsula, Douglas P. Nowacek, Ari S. Friedlaender, Patrick N. Halpin, Elliott L. Hazen, David W. Johnston, Andrew J. Read, Boris Espinasse, Meng Zhou, Yiwu Zhu
Super-Aggregations Of Krill And Humpback Whales In Wilhelmina Bay, Antarctic Peninsula, Douglas P. Nowacek, Ari S. Friedlaender, Patrick N. Halpin, Elliott L. Hazen, David W. Johnston, Andrew J. Read, Boris Espinasse, Meng Zhou, Yiwu Zhu
Environmental, Earth, and Ocean Sciences Faculty Publication Series
Ecological relationships of krill and whales have not been explored in the Western Antarctic Peninsula (WAP), and have only rarely been studied elsewhere in the Southern Ocean. In the austral autumn we observed an extremely high density (5.1 whales per km2) of humpback whales (Megaptera novaeangliae) feeding on a super-aggregation of Antarctic krill (Euphausia superba) in Wilhelmina Bay. The krill biomass was approximately 2 million tons, distributed over an area of 100 km2 at densities of up to 2000 individuals m−3; reports of such ‘super-aggregations’ of krill have been absent in …
Cellulosic Biofuels: Expert Views On Prospects For Advancement, Erin D. Baker, Jeffrey M. Keisler
Cellulosic Biofuels: Expert Views On Prospects For Advancement, Erin D. Baker, Jeffrey M. Keisler
Management Science and Information Systems Faculty Publication Series
In this paper we structure, obtain and analyze results of an expert elicitation on the relationship between U. S. government Research & Development funding and the likelihood of achieving advances in cellulosic biofuel technologies. While there was disagreement among the experts on each of the technologies, the patterns of disagreement suggest several distinct strategies. Selective Thermal Processing appears to be the most promising path, with the main question being how much funding is required to achieve success. Thus, a staged investment in this path looks promising. With respect to gasification, there remains fundamental disagreement over whether success is possible even …

Summary Report: Workshop On International Environmental Governance: Grounding Policy Reform In Rigorous Analysis, Center For Governance And Sustainability At Umass Boston
Center for Governance and Sustainability Publications
From June 27 to 28, 2011, the Federal Office for the Environment of Switzerland, the Global Environmental Governance Project of the Center for Governance and Sustainability at the University of Massachusetts Boston, and the World Trade Institute at the University of Bern hosted a workshop on International Environmental Governance: Grounding Policy Reform in Rigorous Analysis. The workshop started a dialogue between academics and researchers on one hand and policymakers on the other in order to provide analytical input to the political negotiations on institutional reform in the run-up to the UN Conference on Sustainable Development in 2012.
The workshop focused …
