Evaluation for Continuing Education provides the useful and practical tools necessary to ensure a successful program evaluation. The book presents systematic guidelines aimed at enhancing understanding of evaluation concepts and procedures, and offers manageable ways to selectively include evaluation activities as an integral part of program planning, implementation, and justification. Author Alan Knox reveals that the key to successful evaluations that improve education programs for adults is a basic rationale for why and how. He helps readers select and develop their own rationale throughout the course of the book while suggesting fundamental evaluation concepts and procedures. He shows how to distinguish some program aspect upon which a specific evaluation project will focus-including needs assessment, goals and policies, staffing assessment, materials development, and more-and summarizes examples of evaluation reports that reflect the various types of providers and scales on which evaluations are conducted. Knox offers a particularly wide variety of these examples, enabling readers to reflect on implications for their own evaluations and fashion unique guidelines and procedures that fit their own situations.

Nitrogen is indispensable to all life on Earth. However, humans now dominate the nitrogen cycle, and nitrogen emissions from human activity have real costs: water and air pollution, climate change, and detrimental effects on human health, biodiversity, and natural habitats. Too little nitrogen limits ecosystem processes, while too much nitrogen transforms ecosystems profoundly. The California Nitrogen Assessment is the first comprehensive account of nitrogen flows, practices, and policies for California, encompassing all nitrogen flows—not just those associated with agriculture—and their impacts on ecosystem services and human wellbeing. How California handles nitrogen issues will be of interest nationally and internationally, and the goal of the assessment is to link science with action and to produce information that affects both future policy and solutions for addressing nitrogen pollution. This book also provides a model for application of integrated ecosystem assessment methods at regional and state (subnational) levels.

This two-volume set collects key essays examining economic theory, methods, and issues salient to agri-environmental policy in the US and in Europe, as well as in other countries. The topics under discussion are arranged thematically and include theoretical, numerical and empirical works; all are grounded in policy and economics. The introduction to these volumes reviews the evolution of agri-environmental policies, with an important focus on the history of US policy and European agri-environmental policy. A key feature within this is the importance of the Environmental Protection Agency (EPA) in the US, particularly its move towards more 'market-based incentives' from the 1980s onwards. Within the European context, the effects of the CAP (Common Agricultural Policy) on agri-environmental programmes and schemes within the member states, are discussed. Significantly, the essays republished here have provided the knowledge base that has influenced further applied work, creating an influential impact on policy development.
