The GIS Management Handbook: A Comprehensive Guide and Reference for GIS Managers

croswell“The book is comprehensive guide and reference to the field of GIS management. It provides practical information on the development, implementation, and operation of GIS programs and projects and is valuable resource for seasoned and new GIS managers and aspiring managers. IT managers with a requirement to understand more about GIS programs in their organizations will benefit from this book as will providers of technical and management services needing to learn more about the GIS programs they serve. The book is also a useful reference for academicians and students studying or researching GIS management issues.”

Frontiers in Soil Science Research: Report of a Workshop

sswsFrom the Steering Committee for Frontiers in Soil Science Research; National Research Council comes a new National Academies Press book titled Frontiers in Soil Science Research: Report of a Workshop.

There has been renewed interest in soil and soil science in recent years as the recognition that biogeochemical processes that occur at the Earth’s surface influence global climate change, land degradation and remediation, the fate and transport of nutrients and contaminants, soil and water conservation, soil and water quality, food sufficiency and safety, and many other issues pertinent to the stewardship and conservation of land and water resources. In some areas of the Earth we have approached near irreversible soil conditions that may threaten the existence of future generations. Understanding the long-term implications of decreased soil quality and addressing the aforementioned challenges will require new information based on advances and breakthroughs in soil science research that need to be effectively communicated to stakeholders, policy makers, and the general public.

On December 12-14, 2005, the National Academies convened the Frontiers in Soil Science Research Workshop, summarized in this volume, to identify emerging areas for research in soil science by addressing the interaction of soil science subdisciplines, collaborative research with other disciplines, and the use of new technologies in research. The workshop focused around seven key questions addressing research frontiers for the individual soil science disciplines, and also addressing the need for integration across soil science with other disciplines.

New Book: Science and Decisions

0309120462From the Committee on Improving Risk Analysis Approaches Used by the U.S. EPA, National Research Council, comes a new National Academies Press book titled Science and Decisions.

Risk assessment has become a dominant public policy tool for making choices, based on limited resources, to protect public health and the environment. It has been instrumental to the mission of the U.S. Environmental Protection Agency (EPA) as well as other federal agencies in evaluating public health concerns, informing regulatory and technological decisions, prioritizing research needs and funding, and in developing approaches for cost-benefit analysis.

However, risk assessment is at a crossroads. Despite advances in the field, risk assessment faces a number of significant challenges including lengthy delays in making complex decisions; lack of data leading to significant uncertainty in risk assessments; and many chemicals in the marketplace that have not been evaluated and emerging agents requiring assessment.

Science and Decisions makes practical scientific and technical recommendations to address these challenges. This book is a complement to the widely used 1983 National Academies book, Risk Assessment in he Federal Government (also known as the Red Book). The earlier book established a framework for the concepts and conduct of risk assessment that has been adopted by numerous expert committees, regulatory agencies, and public health institutions. The new book embeds these concepts within a broader framework for risk-based decision-making. Together, these are essential references for those working in the regulatory and public health fields.

“The report is a major accomplishment. It courageously addresses questions that many of its legendary predecessors and most other works on risk assessment either don’t ask or fail to answer.”

Construction of a Household-level Public Transportation Accessibility Model

urisaThird Place, 2009 URISA Student Paper Competition

Calvin Tribby, University of New Mexico

“This research details the construction of a public transportation accessibility model, with a focus on the necessity of using travel time as the accessibility measure.  The primary objective of this work is to explain how this multi-modal network model was built and to highlight its usefulness through a representative example of its application.  This method is situated in the accessibility measures of transportation equity, a focus of research in the broader field of transportation geography.  The level of detail that current accessibility studies use to evaluate public transit are not detailed enough to capture travel time changes at the household level and through varying time periods throughout the day.  The result of this research is the successful application of this network to highlight the travel time changes at the household level of new transit investments, with implications for a finer level of social justice studies.”
