2010 Massachusetts Recreational Boater Survey: Final Report Submitted To The Massachusetts Ocean Partnership, Dan Hellin, Jack Wiggin, Kristin Uiterwyk, Kim Starbuck, Nicholas Napoli, David Terkla, Chris Watson, Anthony Roman, Leona Roach, Tim Welch

David G. Terkla

The Massachusetts Ocean Management Plan (Plan) completed in 2009 recognized recreational boating as an activity with “significant actual and prospective conflicts among multiple waterway uses in Massachusetts” and included the economic value of recreational boating as a key socio-economic indicator that will be used to inform coastal management. At the time of Plan completion, statistically robust recreational boating data were identified as an important need for comprehensive ocean planning. To fill this data gap, the 2010 Massachusetts Recreational Boater Survey gathered information on boating activity in Massachusetts’ coastal and ocean waters directly from recreational boaters. Researchers sent 10,000 surveys to …

The Value Of Government Mandated Location-Based Services In Emergencies In Australia, Anas Aloudat, Katina Michael, Roba Abbas, Mutaz M. Al-Debei Dec 2011

The Value Of Government Mandated Location-Based Services In Emergencies In Australia, Anas Aloudat, Katina Michael, Roba Abbas, Mutaz M. Al-Debei

Dr. Mutaz M. Al-Debei

The adoption of mobile technologies for emergency management has the capacity to save lives. In Australia in February 2009, the Victorian Bushfires claimed 173 lives, the worst peace-time disaster in the nation’s history. The Australian government responded swiftly to the tragedy by going to tender for mobile applications that could be used during emergencies, such as mobile alerts and location services. These applications, which are becoming increasingly accurate with the evolution of positioning techniques, have the ability to deliver personalized information direct to the citizen during crises, complementing traditional broadcasting mediums like television and radio. Indeed governments have a responsibility …

Spatial Analysis Of Fatal Automobile Crashes In Kentucky, William Nathan Oris

Masters Theses & Specialist Projects

Fatal automobile crashes have claimed the lives of over 33,000 people each year in the United States since 1995. As in any point event, fatal crash events do not occur randomly in time or space. The objectives of this study were to identify spatial patterns and hot spots in FARS (Fatal Analysis Reporting System) fatal crash events based on temporal and demographic characteristics. The methods employed included 1) rate calculation using FARS points and average daily traffic flow; 2) planar kernel density estimation of FARS crash events based on temporal and demographic attributes within the data; and 3) two case …


The Urban Fabric Of The Great Plains, Andrew Becker Dec 2011

The Urban Fabric Of The Great Plains, Andrew Becker

Department of Environmental Studies: Undergraduate Student Theses

To most Americans the Great Plains region of North America is mysterious place. There are disagreements when defining its limits, and some people just refer to it as the Midwest. The Great Plains has been a place under an ocean, a place under glaciers, and a place on fire. It was once dubbed “the Great American Desert,” but is now known for its agricultural viability. The Great Plains sparks imagination because it is so massive and was one of the final frontiers for Euro-American settlement. The Great Plains is seen as a rural place but the majority of the region’s …

Ecological Revival And Sustainable Living In The Tropical Dry Evergreen Forest Of Tamil Nadu: A Measurement Of Residential Perception In Sadhana Forest, Elizabeth Collette Mcguire

Department of Environmental Studies: Undergraduate Student Theses

Since 1970, the role and function of the U.S. Environmental Protection Agency (EPA) has been to promote environmental quality and to form strategies for carrying out environmental policy1. The EPA has committed to sustainability as the next level of environmental protection. The agency states that sustainability calls for policies and strategies that meet society’s present needs without compromising the ability of future generations to meet their own needs2. Presently, society’s requirements have resulted in natural resource exploitation and population distention- projected to reach 10 billion people within two human generations3. These paired occurrences are …


Development Of A Simulation Tool For Analysis Of Freeway Crashes Due To Cell Phone Usage, Sourabh Sriom Dec 2011

Development Of A Simulation Tool For Analysis Of Freeway Crashes Due To Cell Phone Usage, Sourabh Sriom

UNLV Theses, Dissertations, Professional Papers, and Capstones

Research shows that drivers are susceptible to numerous distractions while driving which can be held responsible as the reason of a crash. Usage of cell phones, i.e. talking or texting while driving is considered one of the prominent distractions which causes a crash. This dissertation aims to study the number of crashes occurring on the freeways and their relation with the drivers of these cars using cell phones while they are driving. Since crashes occur relatively less frequently, the study of crashes is done using what is called the "rare event" theory. Java based simulations are done to model a …


The Social And Behavioral Implications Of Location-Based Services, Katina Michael, M.G. Michael Nov 2011

The Social And Behavioral Implications Of Location-Based Services, Katina Michael, M.G. Michael

Associate Professor Katina Michael

The social and behavioral implications of location-based services (LBS) are only now beginning to come to light in advanced markets where the services have been adopted by just a little over half the market (Microsoft 2011). Depending on one’s definition of what constitutes location-based services, statistics on the level of adoption differ considerably. While it is helpful to provide as broad a list of applications as possible in what constitutes LBS (e.g. everything from in-vehicle navigation systems to downloading a map using a computer), it can also cloud the real picture forming behind this emerging technology. Emerging not in the …


A Pomdp Model For Guiding Taxi Cruising In A Congested Urban City, Lucas Agussurja, Hoong Chuin Lau Nov 2011

A Pomdp Model For Guiding Taxi Cruising In A Congested Urban City, Lucas Agussurja, Hoong Chuin Lau

Research Collection School Of Computing and Information Systems

We consider a partially observable Markov decision process (POMDP) model for improving a taxi agent cruising decision in a congested urban city. Using real-world data provided by a large taxi company in Singapore as a guide, we derive the state transition function of the POMDP. Specifically, we model the cruising behavior of the drivers as continuous-time Markov chains. We then apply dynamic programming algorithm for finding the optimal policy of the driver agent. Using a simulation, we show that this policy is significantly better than a greedy policy in congested road network.

Reconsidering Accountability For Environmental Inspectors: Trading 'Compliance By Computer' For Relationship Building, Michelle C. Pautz Oct 2011

Reconsidering Accountability For Environmental Inspectors: Trading 'Compliance By Computer' For Relationship Building, Michelle C. Pautz

Political Science Faculty Publications

Demands for government accountability extend into all the aspects of government service and the environmental realm is no different. Environmental inspectors — the front-line workers in environmental protection agencies — are among the many civil servants who face demands for accountability. Unfortunately, although accountability is desirable normatively speaking, in practice it is not so simple. Accountability for environmental inspectors frequently involves measures such as the number of inspections completed, the efficiency of data entry in agency databases, and the turnaround time on inspection reports. Such measures leave environmental inspectors, who ideally want — and practically need — to be in …

Local Solutions For A Global Problem: The Role Of Ngos In Maximizing The Efficacy Of Local Government Sanitation Efforts In Rural Maharashtra, Jorge Aceves Oct 2011

Local Solutions For A Global Problem: The Role Of Ngos In Maximizing The Efficacy Of Local Government Sanitation Efforts In Rural Maharashtra, Jorge Aceves

Independent Study Project (ISP) Collection

This independent study project looks at the topic of sanitation within rural Maharashtra. Although the Government of India, through the state governments, has initiated nationwide campaigns against poor sanitation and waterborne illnesses, these programmes do not reach all communities or find significant success in improving sanitation. Recent revisions of these sanitations programs have shifted their focus from a centralized supply-driven approach to a localized demand-driven approach, yet the system requires more work to become fully functional. In some areas, non-government organizations, such as the Comprehensive Rural Help Project (CRHP), have stepped up to bridge the gap between the available government …

Recommendations For Australia’S Implementation Of The National Emergency Warning System Using Location-Based Services, Anas Aloudat, Katina Michael, Roba Abbas

Professor Katina Michael

Mobile alerts, notifications and location-based emergency warning systems are now an established part of mobile government strategies in an increasing number of countries worldwide. In Australia the national emergency warning system (NEWS) was instituted after the tragic Black Saturday Victorian Bushfires of February 2009. In the first phase, NEWS has enabled the provision of public information from the government to the citizen during emergencies anywhere and any time. Moving on from traditional short message service (SMS) notifications and cell broadcasting to more advanced location-based services, this paper provides executive-level recommendations about the viability of location-based mobile phone services in NEWS …
