Christopher G. Smith, Miriam C. Jones, Lisa Osterman, Davina Passeri
2020, Marine Geology (427)
A high degree of uncertainty exists for understanding and predicting coastal estuarine response to changing climate, land-use, and sea-level conditions, leaving geologic records as a best-proxy for constraining potential outcomes. With the majority of the world's population focused in coastal regions, understanding how local systems respond to global, regional, and...
Introduction to structuring decisions
David R. Smith
2020, Book chapter, Structured decision making: Case studies in natural resource management
Decision structuring, also known as decision framing, provides the foundation and roadmap for analyzing a decision. For decisions that warrant a systematic approach, structuring begins with identifying the problem for analysis, which sounds simple but can be deceptively difficult because decision problems are often ill-formed at the start....
