A number of excellent textbooks on general ecology are currently available but' to date' none have been dedicated to the study of soil ecology. This is important because the soil' as the 'epidermis' of our planet' is the major component of the terrestrial biosphere. In the present age' it is difficult to understand how one could be interested in general ecology without having some knowledge of the soil and further' to study the soil without taking into account its biological components and ecological setting. It is this deficiency that the two authors' Patrick Lavelle and Alister Spain' have wished to address in writing their text. A reading of this work' entitled 'Soil Ecology'' shows it to be very complete and extremely innovative in its conceptual plan. In addition' it follows straightforwardly through a development which unfolds over four substantial chapters. Firstly' the authors consider the soil as a porous and finely divided medium of b- organomineral origin' whose physical structure and organisation foster the development of a multitude of specifically adapted organisms (microbial communities' roots of higher plants' macro-invertebrates).

This book is written for engineering faculty and department chairs as a practical guide to improving the assessment processes for undergraduate and graduate engineering education in the service of improved student learning. It is written by engineering faculty and assessment professionals who have many years of experience in assessment of engineering education and of working with engineering faculty.The book reflects the emphasis placed on student outcomes assessment by ABET, Inc., the organization that accredits most U.S. engineering, computer science and technology programs, as well as providing substantial equivalency evaluations to international engineering programs. The book begins with a brief overview of assessment theory and introduces readers to key assessment resources. It illustrates-through practical examples that reflect a wide range of engineering disciplines and practices at both large and small institutions, and along the continuum of students' experience, from first year to capstone engineering courses through to the dissertation-how to go about applying formative and summative assessment practices to improve student learning at the course and program levels. For most institutions, assessment of graduate education is new; therefore, there are readers who will be particularly interested in the chapters and examples related to graduate education. This book concludes with a vision for the future of assessment for engineering education. The authors cover five basic themes: -Use of assessment to improve student learning and educational programs at both undergraduate and graduate levels-Understanding and applying ABET criteria to accomplish differing program and institutionalmissions-Illustration of evaluation/assessment activities that can assist faculty in improving undergraduate and graduate courses and programs-Description of tools and methods that have been demonstrated to improve the quality of degree programs and maintain accreditation-Identification of methods for overcoming institutional barriers and challenges to implementing assessment initiatives
