Guidelines 13 and 14—Prediction uncertainty Guidelines 13 and 14—Prediction uncertainty
An advantage of using optimization for model development and calibration is that optimization provides methods for evaluating and quantifying prediction uncertainty. Both deterministic and statistical methods can be used. Guideline 13 discusses using regression and post-audits, which we classify as deterministic methods. Guideline 14 discusses inferential statistics and Monte Carlo...

Calibrating transient and transport models and recalibrating existing models Calibrating transient and transport models and recalibrating existing models
The methods presented in Chapters 3 to 8 are applicable to models of any system. However, there are special considerations when applying the methods to certain types of models. This chapter discusses three types of models that are of special interest to many scientific and engineering fields: transient models, transport models, and existing models that are to be recalibrated.

The manly map: the English construction of gender in early modern cartography The manly map: the English construction of gender in early modern cartography
Questions of gender in cartography most often focus on the sex of people involved in the cartographic process. These areas of research include the history of women cartographers (Tyner 1997: 46; Ritzlin 1989: 5; Hudson 1989: 29), the cartography of issues centered on women (Seager and Olson 1986; Seager et al. 1997; Rocheleau et al. 1995: 62), and women in the cartographic labor force...

Remote sensing of coastal environments Remote sensing of coastal environments
Coastal ecosystems are transitional environments that are sensitively balanced between open water and upland landscapes. Worldwide, they exhibit extreme variations in areal extent, spatial complexity, and temporal variability. Sustaining these ecosystems requires the ability to monitor their biophysical features and controlling processes at high spatial and temporal resolutions but...

Conclusion Conclusion
This book has presented what is known about the extent and causes of amphibian population declines in the United States and what can be done about them. It has also examined life history and natural history features needed to manage for amphibians, with a current assessment of their distribution. In assembling the literature for this project, and with a quick look at the species accounts...
