Agrarian Landscapes in Transition researches human interaction with the earth. With hundreds of acres of agricultural land going out of production every day, the introduction, spread, and abandonment of agriculture represents the most pervasive alteration of the Earth's environment for several thousand years. What happens when humans impose their spatial and temporal signatures on ecological regimes, and how does this manipulation affect the earth and nature's desire for equilibrium? Studies were conducted at six Long Term Ecological Research sites within the US, including New England, the Appalachian Mountains, Colorado, Michigan, Kansas, and Arizona. While each site has its own unique agricultural history, patterns emerge that help make sense of how our actions have affected the earth, and how the earth pushes back. The book addresses how human activities influence the spatial and temporal structures of agrarian landscapes, and how this varies over time and across biogeographic regions. It also looks at the ecological and environmental consequences of the resulting structural changes, the human responses to these changes, and how these responses drive further changes in agrarian landscapes. The time frames studied include the ecology of the earth before human interaction, pre-European human interaction during the rise and fall of agricultural land use, and finally the biological and cultural response to the abandonment of farming, due to complete abandonment or a land-use change such as urbanization.
The history of the use of ultrasound in medicine has been one of evolution of technology and innovative methods of applying this technology to imaging body structures. Many scientists and clinicians have contributed to this evolution. Ophthalmic ultrasound has become an indispensible tool in ophthalmic practice, with its own instrumentation and techniques. Ultrasound frequencies used in ophthalmology have generally been higher than those used in general medicine because of a requirement for higher resolution and a lesser need for deep penetration. Most ophthalmic diagnostic equipment uses frequencies in the 10 MHz range. The use of ultrasound frequencies in the 50-100 MHz range is a relatively new development in ultrasound imaging of the eye. This technique has been developed in our laboratories over the past several years. We have progressed from the theoretical description of the basic science required, past the first in-vitro experiments in eye bank eyes, to the construction of an instrument capable of clinical application. We have gained broad clinical experience with this instrument in normal patients and patients with ocular disease. A commercial instrument based on our original clinical scanner has recently become available, allowing other clinicians to apply this tool to ophthalmic research and clinical practice. We have applied the term ultrasound biomicroscopy to this new imaging technique because of similarities to optical biomicroscopy, i. e. , the observation of living tissue at microscopic resolution.
Mainline Protestant congregations face a profound adaptive challenge. In the midst of significant social, cultural, and technological change, the denominations they represent generally abandoned a view of education capable of maintaining and renewing their faith traditions through their children and youth. New curriculum resources and innovative pedagogical strategies appropriated from the marketplace of religious education options have not met the challenge. A transformation of consciousness is required in congregations seeking a future through their children. It involves the exercise of an ecclesial imagination to reclaim a view of education rooted in the revitalization of their religious traditions in the past and re-envisioning the congregation as a catechetical culture of faith formation.
A leading Christian educator offers a practical guide for revisioning a church's educational program. After identifying the weaknesses in current education programs, Charles Foster offers an alternative vision that is more cooperative, more attentive to the whole of the congregation's life, and that helps people critically correlate the Bible and Christian tradition to their own experience.
This study is concerned with the ways in which a dozen " knowledge-based societies" of Western Europe and the English-speaking world respond to unprecedented cultural and linguistic diversity resulting from the flow of immigrants and refugees since World War II. It asks how public policy has sought to use schooling to minimize the potentially divisive and inequitable effects of this diversity and to provide opportunities to the children of immigrants. It asks also how the nature of each of these societies affects the meaning of integration into each of them.
The objective of this book is to present in a concise manner what is actually known at the present time about biological effects of time invariant, low frequency and radio frequency (including microwave) electric and magnetic fields. In reviewing the vast amount of experimental data which have been obtained in recent years, the authors tried to select those results that are, in their opinion, of major importance and of lasting value. In discussing mechanisms of interaction of electromagnetic fields with living matter they have tried to differentiate between what is clearly established, what is suggested by available evidence without being convincingly proven, and what is conjecture at the present time.
The evolution of the eye spans 3.75 billion years from single cell organisms with eyespots to Metazoa with superb camera style eyes. At least ten different ocular models have evolved independently into myriad optical and physiological masterpieces. The story of the eye reveals evolution's greatest triumph and sweetest gift. This book describes its journey"--Provided by publisher.
Law and Society in England 1750–1950 is an indispensable text for those wishing to study English legal history and to understand the foundations of the modern British state. In this new updated edition the authors explore the complex relationship between legal and social change. They consider the ways in which those in power themselves imagined and initiated reform and the ways in which they were obliged to respond to demands for change from outside the legal and political classes. What emerges is a lively and critical account of the evolution of modern rights and expectations, and an engaging study of the formation of contemporary social, administrative and legal institutions and ideas, and the road that was travelled to create them. The book is divided into eight chapters: Institutions and Ideas; Land; Commerce and Industry; Labour Relations; The Family; Poverty and Education; Accidents; and Crime. This extensively referenced analysis of modern social and legal history will be invaluable to students and teachers of English law, political science, and social history.
The new edition of the classic Helping Traumatized Families not only offers clinicians a unified, evidence-based theory of the systemic impact of traumatic stress—it also details a systematic approach to helping families heal by promoting their natural healing resources. Though the impact of trauma on a family can be growth producing, some families either struggle or fail to adapt successfully. Helping Traumatized Families guides practitioners around common pitfalls and toward a series of evidence-based strategies that they can use to help families feel empowered and ultimately to thrive by developing tools for enhancing resilience and self-regulation.
