This book offers an account of a number of aspects of operator theory, mainly developed since the 1980s, whose problems have their roots in quantum theory. The research presented is in non-commutative operator approximation theory or, to use Halmos' terminology, in operator approximants. Focusing on the concept of approximants, this self-contained book is suitable for graduate courses.
In the fall of 1983, arguably the coldest year of the decades-long Cold War, the world's greatest superpower invaded Grenada, a Marxist-led Caribbean nation the size of Atlanta. Why and how this unlikely one-week war was waged was shrouded in secrecy at the time--and has remained so ever since. This book is an overdue reconsideration of Operation Urgent Fury, based on historical evidence that only recently has been revealed in declassified documents, oral history interviews and memoir accounts. This chronological narrative emphasizes the human dimension of a sudden crisis now regarded as the greatest foreign policy challenge of President Ronald Reagan's first term. Because the American intervention was hastily drafted, many snafus and accidents marked the chaotic initial days of the operation. Inevitably it fell to individual soldiers, aviators and sailors to perform heroic acts to make up for faulty intelligence, inadequate communication or poor coordination. This work recounts their inspiring, underreported stories in filling out a more complete portrait of Operation Urgent Fury. The final chapter recounts the invasion's aftereffects, especially the unexpected role it played in Congressional reform of the military for future combat in the Middle East.
Asynchronicity is a study of the information stress and its genesis in the accelerative dynamics of computation and automation. In simple terms, this volume illustrates how anti-democratic communication has become characteristic of our present social and political reality. This book is significant in two respects. By fully realising a general theory of social time, it advances temporal analysis as a mode of social enquiry. Grounding the production of time within the event-dynamics of media systems, it establishes a framework for analysing the temporal logics of digital media, and shows that they may be fundamentally incompatible with the requirements of democratic communication.
It has been over 50 years since Hans Selye formulated his concept of stress. This came after the isolation of epinephrine and norepinephrine and after the sympathetic system was associated with Walter Cannon's "fight or flight" response. The intervening years have witnessed a number of dis coveries that have furthered our understanding of the mechanisms of the stress response. The isolation, identification and manufacture of gluco corticoids, the identification and synthesis of ACTH and vasopressin, and the demonstration of hypothalamic regulation of ACTH secretion were pivotal discoveries. The recent identification and synthesis of CRR by Willie Vale and his colleagues gave new impetus to stress research. Several new concepts of stress have developed as a result of advances in bench research. These include the concept of an integrated "stress sys tem", the realization that there are bi-directional effects between stress and the immune system, the suggestion that a number of common psychiatric disorders represent dysregulation of systems responding to stress, and the epidemiologic association of stress with the major scourges of humanity.
In Hebrews and the Temple Philip Church argues that the silence of Hebrews concerning the temple does not mean that the author is not interested in the temple. He writes to encourage his readers to abandon their preoccupation with it and to follow Jesus to their eschatological goal. Following extensive discussions of attitudes to the temple in the literature of Second Temple Judaism, Church turns to Hebrews and argues that the temple is presented there as a symbolic foreshadowing of the eschatological dwelling of God with his people. Now that the eschatological moment has arrived with the exaltation of Christ to the right hand of God, preoccupation with the temple and its rituals must cease.
