ecological support for rural land use planning
Ecological Applications, 2005Co-Authors: David M. Theobald, Thomas A. Spies, Jeffrey D. Kline, Bruce D. Maxwell, N. T. Hobbs, Virginia H. DaleAbstract:How can ecologists be more effective in supporting ecologically informed rural land-use planning and policy? Improved Decision Making about rural lands requires careful consideration of how ecological information and analyses can inform specific planning and policy needs. We provide a brief overview of rural land-use planning, including recently developed approaches to conservation. Effective participation in land-use planning requires ecologists to understand trade-offs—for example, the need to balance a land owner's desire for a fair and predictable process with the “learn as you go” approach of adaptive management—and the importance of integrating local knowledge with landscape-level information. Four primary challenges require attention from ecologists to improve rural land-use planning. First is the mismatch between the spatial and temporal scales in which ecological processes occur and the scales and tempos of land-use planning. Second, ecologists must engage in interdisciplinary research to critica...

a streamlined sustainability assessment tool for Improved Decision Making in the urban water industry
Integrated Environmental Assessment and Management, 2012Co-Authors: Matthias Schulz, Michael D Short, Gregory PetersAbstract:Water supply is a key consideration in sustainable urban planning. Ideally, detailed quantitative sustainability assessments are undertaken during the planning stage in order to inform the Decision-Making process. In reality, however, the significant time and cost associated with undertaking such detailed environmental and economic assessments is often cited as a barrier to wider implementation of these key Decision-support tools, particularly for Decisions made at the local or regional government level. In an attempt to overcome this barrier of complexity, four water service providers in Melbourne (Australia) funded the development of a publicly available streamlined Environmental Sustainability Assessment Tool (ESAT). The tool is aimed at a wide range of Decision-makers to assist them in broadening the type and number of water servicing options that can be considered for greenfield or backlog developments. ESAT consists of a simple user interface and draws upon life cycle inventory data to allow for rapid estimation of the environmental and economic performance of different water servicing scenarios. Scenario options can then be further prioritised by means of an interactive multicriteria analysis. The intent of this paper is to identify the key issues to be considered in a streamlined sustainability assessment tool for the urban water industry and to demonstrate the feasibility of generating accurate life cycle assessments (LCAs) and life cycle costings (LCCs) using such a tool. We use a real-life case study example consisting of three separate scenarios for a planned urban development to show that this kind of tool can emulate LCA and LCC outcomes obtained through more detailed studies. This simplified approach is aimed at supporting ‘sustainability thinking’ early on in the Decision-Making process, thereby encouraging more sustainable water and sewerage infrastructure solutions.

modeling subpopulations with the mixture subroutine in nonmem finding the individual probability of belonging to a subpopulation for the use in model analysis and Improved Decision Making
Aaps Journal, 2009Co-Authors: Kristin C Carlsson, Radojka M Savi, Andrew C Hooker, Mats O KarlssonAbstract:In nonlinear mixed effects modeling using NONMEM, mixture models can be used for multimodal distributions of parameters. The fraction of individuals belonging to each of the subpopulations can be estimated, and the most probable subpopulation for each patient is output (MIXESTk). The objective function value (OFV) that is minimized is the sum of the OFVs for each patient (OFVi), which in turn is the sum across the k subpopulations (OFVi,k). The OFVi,k values can be used together with the total probability in the population of belonging to subpopulation k to calculate the individual probability of belonging to the subpopulation (IPk). Our objective was to explore the information gained by using IPk instead of or in addition to MIXESTk in the analysis of mixture models. Two real data sets described previously by mixture models as well as simulations were used to explore the use of IPk and the precision of individual parameter values based on IPk and MIXESTk. For both real data-based mixture models, a substantial fraction (11% and 26%) of the patients had IPk values not close to 0 or 1 (IPk between 0.25 and 0.75). Simulations of eight different scenarios showed that individual parameter estimates based on MIXEST were less precise than those based on IPk, as the root mean squared error was reduced for IPk in all scenarios. A probability estimate such as IPk provides more detailed information about each individual than the discrete MIXESTk. Individual parameter estimates based on IPk should be preferable whenever individual parameter estimates are to be used as study output or for simulations.
