Due Process And Punitive Damages: The Error Of Federal Excessiveness Jurisprudence, A. Benjamin Spencer Jul 2006

Due Process And Punitive Damages: The Error Of Federal Excessiveness Jurisprudence, A. Benjamin Spencer

Faculty Publications

The Supreme Court, in a line of several cases over the past decade, has established a rigorous federal constitutional excessiveness review for punitive damages awards based on the Due Process Clause. As a matter of substantive due process, says the Court, punitive awards must be evaluated by three "guideposts" set forth in BMW of North America v. Gore: the degree of reprehensibility of the defendant's conduct, the ratio between punitive and compensatory damages, and a comparison of the amount of punitive damages to any "civil or criminal penalties that could be imposed for comparable misconduct." Following up on this pronouncement …

Air Quality Modelling: State-Of-The-Art, R. San José, A. Baklanov, R. S. Sokhi, Kostas Karatzas, J. L. Pérez

International Congress on Environmental Modelling and Software

Air quality modeling is an area with a significant progress and interest during the last two decades. It covers all aspects related to pollution dispersion and impact on different ecosystems. It is very much related to the meteorological field since the atmosphere is governed by the general laws derived by the Navier-Stokes equation system. Progress in computer capabilities during the last decades has impulse substantially the research on air quality modeling in a parallel way. Air pollution modeling covers a very complex and interdisciplinary area where we include remote sensing – land use impact -, initial and boundary conditions, data …

Impacts Of Agriculture And Dairy Farming On Groundwater Quality: An Optimization Problem, Tomaz Dentinho, R. Minciardi, M. Robba, Roberto Sacile, V. Silva

International Congress on Environmental Modelling and Software

A decision model for groundwater quality preservation in areas affected by intensive agriculture and dairy farming, with specific reference to the Azores islands, is presented. In these islands, the exigency to find appropriate instruments to support decisions in Integrated Water Management (IWM) is particularly felt because the increase of tourism and the dairy farming have increased water demands and depletion of water quality. An optimization problem, in terms of decision variables, objectives, and constraints is formalized. The physical/chemical/ecological models are embedded as constraints in the decision model. Specifically, four types of models (hydraulic model, chemical model, agricultural model, and dairy …

Development Of An Integrated Decision Support System For Water Quality Control In The Upper Litani Basin, Lebanon, Hamed Assaf, Mark Saadeh

International Congress on Environmental Modelling and Software

Compared to the limited water supply in the Middle East, Lebanon is perceived to be a water rich country. Yet, it faces a growing water supply problem due to many factors including increases in demand, inadequate investment in infrastructure, and deterioration of water quality. Being the foremost water resource in Lebanon, the Litani River is at the center of several major water supply and irrigation schemes. However, the river water quality is severely impacted by the current practice of releasing untreated sewage into its water body, specifically in its upper basin which is home to about half a million inhabitants. …

A Conceptual Software System For Water Allocation, Planning And Catchment Management, R. M. Argent, Peter Gijsbers, Jean-Michel Perraud, G. M. Podger

International Congress on Environmental Modelling and Software

Water resources management is increasingly dealing with competing demands for fixed or diminishing available supplies. In this , the allocation and accounting of water consumption between competing users, including environmental uses, plays a critical role. Various software tools have been developed to cover aspects of water resources planning and allocation, operation, and catchment management. In line with the requirements of water management agencies, attention is turning to the development of integrated tools with a broad range of capabilities that include water resource planning under different climatic and allocation policies, water supply under various operating rules and user behaviour, and catchment …


Multi-Scale Analysis And Modelling Of Natural Resource Management Options, Frank Ewert, Herman Van Keulen, Martin Van Ittersum, Ken Giller, Peter Leffelaar Jul 2006

Multi-Scale Analysis And Modelling Of Natural Resource Management Options, Frank Ewert, Herman Van Keulen, Martin Van Ittersum, Ken Giller, Peter Leffelaar

International Congress on Environmental Modelling and Software

Problems related to natural resource management (NRM) are typically complex and require integration of information across several scales and disciplines. Operational concepts to support such integration are scarce. Systems analysis and modelling can be helpful but the complexity of environmental systems also requires application of appropriate upscaling methods. Simultaneous assessment and modelling of system behaviour at several levels of organisation poses particular problems. Here, we provide an introductory overview on the critical issues related to multi-scale analysis and modelling of NRM. We describe the problems related to NRM within the context of systems thinking and hierarchy theory. Methods of upscaling …


Bottom-Up, Decision Support System Development : A Wetland Salinity Management Application In California's San Joaquin Valley, N. W. T. Quinn Jul 2006

Bottom-Up, Decision Support System Development : A Wetland Salinity Management Application In California's San Joaquin Valley, N. W. T. Quinn

International Congress on Environmental Modelling and Software

Seasonally managed wetlands in the Grasslands Basin of California’s San Joaquin Valley provide food and shelter for migratory wildfowl during winter months and sport for waterfowl hunters during the annual duck season. Surface water supply to these wetland contain salt which, when drained to the San Joaquin River during the annual drawdown period, negatively impacts downstream agricultural riparian water diverters. Recent environmental regulation, limiting discharges salinity to the San Joaquin River and primarily targeting agricultural non-point sources, now addresses return flows from seasonally managed wetlands. Real-time water quality management has been advocated as a means of matching wetland return flows …

Prorank A Software Tool Used For The Evaluation Of Environmental Databases, S. Pudenz, Rainer Brüggemann, K. Voigt

International Congress on Environmental Modelling and Software

On one hand a lot of research has been performed and an enormous amount of data generated concerning protection of human health and the environment with respect to chemical substances. On the other hand great data gaps for environmental chemicals have been detected in the run-up to a new chemicals policy in the EU, known under the name of REACH. In our approach we elucidate the data availability on chemicals applying the Hasse Diagram Technique (HDT) which originates in discrete mathematics as an environmetrical and chemometrical method. The software package used is ProRank software for multi-criteria evaluation and decision support …


A Protocol For The Development, Evaluation And Application Of Environmental Models In Decision Making, Noha Gaber, Pasky Pascual, Gary Foley, Neil Stiber, Elsie Sunderland Jul 2006

A Protocol For The Development, Evaluation And Application Of Environmental Models In Decision Making, Noha Gaber, Pasky Pascual, Gary Foley, Neil Stiber, Elsie Sunderland

International Congress on Environmental Modelling and Software

Models have emerged as essential tools in environmental management, whether used to further the understanding of complex environmental processes or to inform decisions for environmental planning, remediation, protection or regulation. However, their utility aside, there is also an acknowledgment of their limitations. The question is not whether or not to use models, but rather how best to develop and use models to arrive at credible, defensible and robust decisions and what attributes make a model useful for a given situation. To understand the role of models and decision support tools in environmental management, we must first consider the different types …


Future Solutions: Integrated Models For Sea And Other Land-Use Decision-Making., Ruth Waldick, David Brunckhorst, Ian Campbelld, Jeff Carmichael Jul 2006

Future Solutions: Integrated Models For Sea And Other Land-Use Decision-Making., Ruth Waldick, David Brunckhorst, Ian Campbelld, Jeff Carmichael

International Congress on Environmental Modelling and Software

Since policies should reflect societal values and aspirations, decision-making would benefit from tools that allow consideration of all entities that contribute to, or are affected by decisions. At a minimum, policy should include those key economic, social, and environmental activities taking place within a geophysically relevant area. The barriers that impede the development of integrated modeling programs that try to include many of the processes and outcomes of interest in studying a problem represent a series of common challenges associated with most integrative and cross-jurisdictional projects. Although computer-based modeling and scenario tools can inform the decision-making process, the scope of …


Modelling Farmer Decision Making For Natural Resource Management Outcomes, Brett A. Bryan, J. Ward, Neville D. Crossman Jul 2006

Modelling Farmer Decision Making For Natural Resource Management Outcomes, Brett A. Bryan, J. Ward, Neville D. Crossman

International Congress on Environmental Modelling and Software

This paper presents a conceptual modelling and simulation methodology that incorporates dryland farmer decision making into regional- and landscape-level natural resource management (NRM) planning. Decision making for many NRM on ground actions is made at the farm level so it makes sense to incorporate farmer behaviour into regional planning for meeting regional environmental objectives. Our model applies multi-attribute farmer utility functions within an agent-based simulation environment to model temporal change in land use and landscapes resulting from farmer implementation of on ground NRM actions. Farmer decision profiles are characterized using a survey of over 500 farmers. Landscape futures can also …

Features Of Advanced Decision Support Systems For Environmental Studies, Management, And Regulation, Edwin Roehl, Ruby Daamen, Paul A. Conrads

International Congress on Environmental Modelling and Software

Natural resource managers and users face difficult challenges when managing the interactions between natural and man-made systems. Even though the collective interests and computer skills of the community of managers, scientists, and other stakeholders are quite varied, there is an overarching need for equal access by all to the scientific knowledge needed to make the best possible decisions. A decision support system (DSS) can meet this need. DSS have been described as, “computer-based systems (for) helping decision-makers to solve various semi structured and unstructured problems involving multiple attributes, objectives, and goals… Historically, the majority of DSSs have been either computer …


Data Mining And Image Segmentation Approaches For Classifying Defoliation In Aerial Forest Imagery, K. Fukuda, P. A. Pearson Jul 2006

Data Mining And Image Segmentation Approaches For Classifying Defoliation In Aerial Forest Imagery, K. Fukuda, P. A. Pearson

International Congress on Environmental Modelling and Software

Experimental data mining and image segmentation approaches are developed to add insight towards aerial image interpretation for defoliation survey procedures. A decision tree classifier generated with a data mining package, WEKA [Witten and Frank, 2005], based on the contents of a small number of training data points, identified from known classes, is used to predict the extents of regions containing different levels of tree mortality (severe, moderate, light and non attack) and land cover (vegetation and ground surface). This approach is applicable to low quality imagery without traditional image pre-processing (e.g., normalization or noise reduction). To generate the decision tree, …

Supporting Environmental And Energy Decisions Through An Open Software Structure, Giorgio Guariso, Matteo Baracani

International Congress on Environmental Modelling and Software

Public participation to environmental planning and management decisions, as suggested by localAgenda 21 processes, can be supported by software tools developed with a cyclic interaction with all thestakeholders and simple enough to be quickly operated by a large set of heterogeneous users. This also helpspreventing their rapid aging and their excessive dependence on changing technologies. We experimented thedevelopment of such software tools using an Office type environment to store data, analyse, andgeographically represent the effects of alternative decisions and html files to help utilizing the software anddistributing the information over the Internet. Two different applications are reported in the paper. …

Environmental Policy Aid Under Uncertainty, J. Myšiak, J. D. Brown Jul 2006

Environmental Policy Aid Under Uncertainty, J. Myšiak, J. D. Brown

International Congress on Environmental Modelling and Software

Uncertainty pervades all aspects of environmental policy making. Numerous typologies and techniques have been developed to conceptualise, classify, assess (qualitatively and quantitatively), propagate, control, reduce and communicate uncertainty. Such assessments are a necessary but insufficient condition for reducing uncertainty in environmental decision making. In this paper we discuss how uncertainty is translated into decisions. Since this entails numerous value judgements and trade-offs which are sensitive to how policy problems are framed, we argue that perceptions of uncertainty cannot be viewed independently of the (quality of) the policy process that it intends to inform. Thus, uncertainty management should not be limited …


Generic Simulation Models For Facilitating Stakeholder Involvement In Water Resources Planning And Management, Daniel P. Loucks Jul 2006

Generic Simulation Models For Facilitating Stakeholder Involvement In Water Resources Planning And Management, Daniel P. Loucks

International Congress on Environmental Modelling and Software

The models discussed in this workshop have many features in common, and some that differ. All are what we commonly call decision support systems for analyzing alternative water, and, in some cases, watershed management alternatives. All are interactive, i.e., they use graphic interfaces and are menu driven. After some training interested stakeholders can explore questions and assumptions using these tools. Each model is designed to be flexible enough to fit most if not all water resource systems no matter where located. Each is a tool that can be used, at least as a first step, in the identification and evaluation …

Application Of Mesocasimir: Assessment Of Baetis Rhodani Habitat Suitability, A. M. Mouton, M. Schneider, I. Kopecki, Peter L. M. Goethals, N. De Pauw

International Congress on Environmental Modelling and Software

The assessment of the ecological status of running waters at a mesohabitat scale is commonly based on fish. Nevertheless, due to their strong dependence on a good physical and chemical habitat, macroinvertebrate species can also be used for this assessment. A new approach is presented by applying the MesoCASiMiR module of the CASiMiR modeling system. In this way, the habitat suitability for the mayfly Baetis rhodani was modeled at a mesohabitat scale in the river Zwalm (Flanders, Belgium). The model inference system was based on fuzzy logic. Fuzzy variable sets and rules were derived from expert knowledge and from a …


Landscape Modeling And Spatial Optimization Of Management Practices To Restore Water Quality In The St. Albans Bay Watershed, Vermont, Erica Gaddis, Alexey Voinov Jul 2006

Landscape Modeling And Spatial Optimization Of Management Practices To Restore Water Quality In The St. Albans Bay Watershed, Vermont, Erica Gaddis, Alexey Voinov

International Congress on Environmental Modelling and Software

Diffuse (non-point source) pollution from urban stormwater and agricultural runoff are among the leading causes of water pollution in the United States. Currently, most management plans that address diffuse pollution are driven by dissociated economic, political and ecological interests that are difficult to reconcile. Integrated watershed management aims to protect and improve water resources while considering economic and social concerns in the community. Participatory environmental management requires tools, such as landscape models, that can be used to visualize and evaluate the possible outcomes of various management strategies. The overall objective of this project is to develop and implement a framework …

A Dynamic Model For Sustainable River Basin Management., Paula A. Silva, Paula Antunes, Daniel Borrego, Jojo Rocha, Nuno Videira, Rui Santos

International Congress on Environmental Modelling and Software

The European Water Framework Directive (WFD) introduced an integrated perspective in water resources management, based on an approach where the river basin is the management unit and the active involvement of all affected parties by its river basin management plan is clearly encouraged. The integrated perspective is required to develop sustainable resource management strategies adapted to the institutional, cultural and legal tradition in a region, taking into account the human dimension of the problem. A dynamic model capable of integrating quantitative and qualitative data and relationships between technical, ecological, economic and social driving forces, typical of water resources management problems, …


Use Of Space Technology For Natural Disaster Detection And Prevention, M. Rukieh, Geol Marwan Koudmani Jul 2006

Use Of Space Technology For Natural Disaster Detection And Prevention, M. Rukieh, Geol Marwan Koudmani

International Congress on Environmental Modelling and Software

Space technologies can play important roles in the reduction of disasters. The use of such technologies can be particularly useful in the risk assessment, mitigation and preparedness phases of disaster management. Space technologies are also vital to the early warning and management of the effects of the disaster. In order for the developing countries to be able to incorporate the routine use of space technology-based solutions there is a need to increase awareness, build national capacity and also develop solutions that are customized and appropriate to the needs of the developing world.

A Simulation Model Of Land-Use Change In The Lake Tahoe Basin Of California And Nevada, As Used In A Decision-Support System, Mark L. Hessenflow, David L. Halsing

International Congress on Environmental Modelling and Software

The Tahoe Land-Use Change model is a stochastic, spatially explicit simulation of future land-use change—in particular, development and retirement of individual parcels—in the Lake Tahoe Basin of California and Nevada. The Federal, State, and regional management agencies responsible for the basin are revising and integrating their 20-year plans to meet various goals, including maintaining or improving several environmental (e.g., lake clarity, forest health) and socioeconomic (e.g., affordable housing) characteristics. To assist this effort, the model projects the long-term outcomes of land-use-management decisions, including those relating to existing and potential government regulations, development activities, and conservation practices. The model results are …
