Internationally known for his work in the theory of probability, symbolic logic, analysis of space and time, and philosophical problems of quantum physics, Hans Reichenbach (1891-1953) was one of the twentieth century's most incisive philosophers of science. In this, his last book, first published in 1956, he brought all his previous research and insight to bear on the most intractable and intriguing problem in physics: the elusive nature of time. This far-sighted work of philosophy illuminates the metaphysical questions with which contemporary researchers in cosmology and particle physics must contend. Arguing as he did throughout his career that developments in scientific knowledge must influence philosophy, Reichenbach shows how completely the Kantian a priori--and many of our most basic intuitions about the structure of space and time--are undermined by twentieth-century physics. He shows how the philosophical understanding of time is necessary to understanding contemporary problems of cosmology. This new edition of The Direction of Time, published in the year of Reichenbach's centennial, includes an introduction by Hilary Putnam, one of Reichenbach's most eminent students, describing the metaphysical assumptions and arguments embedded in Reichenbach's philosophy, and their importance for the development of contemporary philosophy pf science.
This report indexes parameters of and describes a means of access to 3,581 wind wave frequency direction spectral observations obtained at the U.S. Army Engineer Waterways Experiment Station Field Research Facility from June 1994 to August 1995, a period that encompasses the DUCK94 Experiment. An iterative maximum likelihood algorithm is used to estimate directional spectra using signals from a spatial array of 16 bottom mounted pressure sensors in about 8 m of water, approximately 900 m offshore. Parameters include characteristic wave height, spectral peak frequency and corresponding peak period, peak wave direction, directional spread, and reflection coefficient. Time series graphs of these parameters, as well as local winds and currents, illustrate the salient climatology.

Direction-of-Arrival (DOA) estimation concerns the estimation of direction finding signals in the form of electromagnetic or acoustic waves, impinging on a sensor or antenna array. DOA estimation is used for locating and tracking signal sources in both civilian and military applications. This authoritative volume provides an overview and performance analysis of the basic DOA algorithms, including comparisons between the various types.The book offers you a detailed understanding of the arrays pertinent to DOA finding, and presents a detailed illustration of the ESPRIT-based DOA algorithms complete with their performance assessments. From antennas and array receiving systems, to advanced topics on DOA estimation, this book serves as a one-stop resource for professionals and students. Nearly 100 illustrations and more than 281 equations support key topics throughout.
The Classic Work on Helping People Become Closer to God Fathers Barry and Connolly see the work of spiritual direction as helping people to develop their relationship with God. In thinking and practice they have absorbed the insights of modern psychotherapy, but have not been absorbed by them. This highly practical book reflects the authors' experience at the Center for Religious Development in Cambridge, Massachusetts, where spiritual direction is available and where directors are trained.
These moving, positive essays witness the experiences of participants in Shalem Institute's group spiritual direction workshops. Each author relates what he or she learned as a member, mentor or facilitator of a spiritual direction group--a community gathered together to seek and share a desire for God in communal silence, dialogue, intercessory prayer and discernment--and adapts it to a specific setting--the family, workplace, congregation, seminary, the homeless. The result is this collection--a loving, gentle testament to the power of spiritual direction groups--that enables young and old, clergy and laity of all faiths to realize, celebrate and proclaim a commonality of greater spiritual purpose. Fluid and well-honed, The Lived Experience of Group Spiritual Direction is of great value to seminarians, graduate students, church organizations, clergy and laity of all faiths, as well as to anyone seeking guidance on the value of group spiritual direction. It features biographies of its numerous contributors.
This collections of essays by leading British and South African scholars, looking at the Boer War, focuses on three aspects: how the British Military functioned; the role of the Boers, Afrikaners and Zulus; and the media presentation of the war to the public.
In late antiquity the rising number of ascetics who joined the priesthood faced a pastoral dilemma. Should they follow a traditional, demonstrably administrative, approach to pastoral care, emphasizing doctrinal instruction, the care of the poor, and the celebration of the sacraments? Or should they bring to the parish the ascetic models of spiritual direction, characterized by a more personal spiritual father/spiritual disciple relationship? Five Models of Spiritual Direction in the Early Church explores the struggles of five clerics (Athanasius, Gregory Nazianzen, Augustine of Hippo, John Cassian, and Pope Gregory I) to reconcile their ascetic idealism with the reality of pastoral responsibility. Through a close reading of Greek and Latin texts, George E. Demacopoulos explores each pastor's criteria for ordination, his supervision of subordinate clergy, and his methods of spiritual direction. He argues that the evolution in spiritual direction that occurred during this period reflected and informed broader developments in religious practices. Demacopoulos describes the way in which these authors shaped the medieval pastoral traditions of the East and the West. Each of the five struggled to balance the tension between his ascetic idealism and the realities of the lay church. Each offered distinct (and at times very different) solutions to that tension. The diversity among their models of spiritual direction demonstrates both the complexity of the problem and the variable nature of early Christianity. Scholars and students of late antiquity, the history of Christianity, and historical theology will find a great deal of interest in Five Models of Spiritual Direction in the Early Church. The book will also appeal to those who are actively engaged in Christian ministry.
This data-rich book demonstrates the value of existing national long-term ecological research in Australia for monitoring environmental change and biodiversity. Long-term ecological data are critical for informing trends in biodiversity and environmental change. The Terrestrial Ecosystem Research Network (TERN) is a major initiative of the Australian Government and one of its key areas of investment is to provide funding for a network of long-term ecological research plots around Australia (LTERN). LTERN researchers and other authors in this book have maintained monitoring sites, often for one or more decades, in an array of different ecosystems across the Australian continent – ranging from tropical rainforests, wet eucalypt forests and alpine regions through to rangelands and deserts. This book highlights some of the temporal changes in the environment that have occurred in the various systems in which dedicated field-based ecologists have worked. Many important trends and changes are documented and they often provide new insights that were previously poorly understood or unknown. These data are precisely the kinds of data so desperately needed to better quantify the temporal trajectories in the environment in Australia. By presenting trend patterns (and often also the associated data) the authors aim to catalyse governments and other organisations to better recognise the importance of long-term data collection and monitoring as a fundamental part of ecologically-effective and cost-effective management of the environment and biodiversity.
Drawing on the writings of Augustine, John of the Cross, Teresa of Avila and others, Keith R. Anderson and Randy D. Reese show that the age-old practice of Christian mentoring is meant to facilitate our growth throughout life. They provide motivation, principles and plans for starting and continuing mentoring relationships.
