Despite its tiny size and seeming marginality to world affairs, the Central American republic of Costa Rica has long been considered an important site for experimentation in cutting-edge environmental policy. From protected area management to ecotourism to payment for environmental services (PES) and beyond, for the past half-century the country has successfully positioned itself at the forefront of novel trends in environmental governance and sustainable development. Yet the increasingly urgent dilemma of how to achieve equitable economic development in a world of ecosystem decline and climate change presents new challenges, testing Costa Rica’s ability to remain a leader in innovative environmental governance. This book explores these challenges, how Costa Rica is responding to them, and the lessons this holds for current and future trends regarding environmental governance and sustainable development. It provides the first comprehensive assessment of successes and challenges as they play out in a variety of sectors, including agricultural development, biodiversity conservation, water management, resource extraction, and climate change policy. By framing Costa Rica as an “ecolaboratory,” the contributors in this volume examine the lessons learned and offer a path for the future of sustainable development research and policy in Central America and beyond.

Rapid changes in business along with better informed customers threaten the traditional sales and procurement process. Thousands of sales and procurement people are threatened with extinction, yet all is not destined to be doom and gloom. A new way of partnering between these two roles can, in fact, create significant value for both organizations. Sales and procurement professionals have a bright future ahead of them if they can respond to six trends that the authors have identified in the business-to-business world. Each trend offers an opportunity to develop a new skill for sales and procurement professionals and adopt a new practice. Because these practices are not yet widely adopted as “best practices”, the authors coin them “next practices.” These trends include: working together to solve complex problems; organizing problem-solving networks across company boundaries; creating processes for live cross-company engagement; facilitating data driven, cross-company interactions fed by digital platforms; providing new personal experiences for individuals and lastly (and most importantly) creating new sources of value for firms. If these trends are adopted by organizations, the ability to co-create means providing significant value to both the sales management team at the supplier and the purchasing management team at the customer. With the alternative being that these job functions will be replaced by web-based or channel-based alternatives that will do most of what they do today at a fraction of the cost. Increasingly, there is no middle ground anymore. SAMs and senior buyers will either evolve into high value-added sales and procurement professionals, or disappear.

In this book, a number of experts from various disciplines take a look at three different strands in learning to model. They examine the activity of modeling from disparate theoretical standpoints, taking into account the individual situation of the individuals involved. The chapters seek to bridge the modeling of communication and the modeling of particular scientific domains. In so doing, they seek to throw light on the educational communication that goes on in conceptual learning. Taken together, the chapters brought together in this volume illustrate the diversity and vivacity of research on a relatively neglected, yet crucially important aspect of education across disciplines: learning to model. A common thread across the research presented is the view that communication and interaction, as fundamental to most educational practices and as a repository of conceptual understanding and a learning mechanism in itself, is intimately linked to elaborating meaningful, coherent, and valid representations of the world. The editors hope this volume will contribute to both the fundamental research in its field and ultimately provide results that can be of practical value in designing new situations for teaching and learning modeling, particularly those involving computers.

User modeling researchers look for ways of enabling interactive software systems to adapt to their users-by constructing, maintaining, and exploiting user models, which are representations of properties of individual users. User modeling has been found to enhance the effectiveness and/or usability of software systems in a wide variety of situations. Techniques for user modeling have been developed and evaluated by researchers in a number of fields, including artificial intelligence, education, psychology, linguistics, human-computer interaction, and information science. The biennial series of International Conferences on User Modeling provides a forum in which academic and industrial researchers from all of these fields can exchange their complementary insights on user modeling issues. The published proceedings of these conferences represent a major source of information about developments in this area.

The field of Artificial Intelligence in Education has continued to broaden and now includes research and researchers from many areas of technology and social science. This study opens opportunities for the cross-fertilization of information and ideas from researchers in the many fields that make up this interdisciplinary research area, including artificial intelligence, other areas of computer science, cognitive science, education, learning sciences, educational technology, psychology, philosophy, sociology, anthropology, linguistics, and the many domain-specific areas for which Artificial Intelligence in Education systems have been designed and built. An explicit goal is to appeal to those researchers who share the perspective that true progress in learning technology requires both deep insight into technology and also deep insight into learners, learning, and the context of learning. The theme reflects this basic duality.

This book constitutes the refereed proceedings of the 8th International Conference on Intelligent Tutoring Systems, ITS 2006, held in Jhongli, Taiwan, June 2006. The book presents 67 revised full papers and 40 poster papers, together with abstracts of 6 keynote talks, organized in topical sections on assessment, authoring tools, bayesian reasoning and decision-theoretic approaches, case-based and analogical reasoning, cognitive models, collaborative learning, e-learning and web-based intelligent tutoring systems, and more.
