First published in 2000. Virtual States challenge the idea that the nation state is dead. In all the hype about the Internet, little thought has been given to the systematic inequalities being brought about by globalisation, and exacerbated by the global spread of the Internet. Jerry Everard argues that new disparities are emerging between the information 'haves' ad the information 'have-nots': between wealthy and poor states; and between the wealthy and poor in wealthy states. Virtual States systematically addresses these inequalities.
The benefits of using technology to remake government seem almost infinite. The promise of such programs as user-friendly "virtual agencies" and portals where citizens can access all sections of government from a single website has excited international attention. The potential of a digital state cannot be realized, however, unless the rigid structures of the contemporary bureaucratic state change along with the times. Building the Virtual State explains how the American public sector must evolve and adapt to exploit the possibilities of digital governance fully and fairly. The book finds that many issues involved in integrating technology and government have not been adequately debated or even recognized. Drawing from a rich collection of case studies, the book argues that the real challenges lie not in achieving the technical capability of creating a government on the web, but rather in overcoming the entrenched organizational and political divisions within the state. Questions such as who pays for new government websites, which agencies will maintain the sites, and who will ensure that the privacy of citizens is respected reveal the extraordinary obstacles that confront efforts to create a virtual state. These political and structural battles will influence not only how the American state will be remade in the Information Age, but also who will be the winners and losers in a digital society.
This unique volume gives an accurate and very detailed description of the functioning and operation of basic nuclear reactors, as emerging from yet unpublished papers by Nobel Laureate Enrico Fermi. In the first part, the entire course of lectures on Neutron Physics delivered by Fermi at Los Alamos is reported, according to the version made by Anthony P French. Here, the fundamental physical phenomena are described very clearly and comprehensively, giving the appropriate physics grounds for the functioning of nuclear piles. In the second part, all the patents issued by Fermi (and coworkers) on the functioning, construction and operation of several different kinds of nuclear reactors are reported. Here, the main engineering problems are encountered and solved by employing simple and practical methods, which are described in detail. This seminal work mainly caters to students, teachers and researchers working in nuclear physics and engineering, but it is of invaluable interest to historians of physics too, since the material presented here is entirely novel.
In 1924, the last caliphate--an Islamic state as envisioned by the Koran--was dismantled in Turkey. With no state in existence that matches the radical Islamic ideal since, al Qaeda, which sees itself as a government in exile, along with its hundreds of affiliate organizations, has failed to achieve its goal of reestablishing the caliphate. It is precisely this failure to create a homeland, journalist Yaakov Lappin asserts, that has necessitated the formation of an unforeseen and unprecedented entity--that is, a virtual caliphate. An Islamist state that exists on computer servers around the world, the virtual caliphate is used by Islamists to carry out functions typically reserved for a physical state, such as creating training camps, mapping out a state's constitution, and drafting tax laws. In Virtual Caliphate, Lappin shows how Islamists, equipped with twenty-first-century technology to achieve a seventh-century vision, soon hope to upload the virtual caliphate into the physical world. Lappin dispels for the reader the mystery of the jihadi netherworld that exists everywhere and nowhere at once. Anyone interested in understanding the international jihadi movement will find this concise treatment compelling and indispensable.
This book is dedicated to the fundamental physical aspects of stability, the influence of structural defects on the properties and structural phase transformations of BCC alloys. The authors present patterns that occur in the structural-phase states of functional alloys with low stability or instability under thermal cycling effects. Structural-phase transformations and the physical laws governing the influence of the thermomechanical effect on the properties of alloys are examined to advance development of technological processes for processing functional materials. Features: Studies the correlation between structural phase states and changes in the physico-mechanical properties of intermetallic compounds Explores the influence of thermomechanical cycling on the properties of functional alloys Details low-stability pretransition states in alloys
Key Topics in Nuclear Structure is the eighth in a well established series of conferences and is devoted to the discussion of significant topics in nuclear structure. Both experimental and theoretical issues at the forefront of current research on the subject are covered by leading physicists. In particular, on the experimental side the state of the art and the envisaged developments in the most important laboratories, where rare isotope beams are available, are reviewed in detail. On the theoretical side, the various approaches to a fundamental theory of nuclear structure starting from the nucleon-nucleon interaction are discussed, ranging from the few-body systems, where ab initio calculations are possible, to the complex nuclei, where the shell model plays a key role.The proceedings have been selected for coverage in:• Index to Scientific & Technical Proceedings® (ISTP® / ISI Proceedings)• Index to Scientific & Technical Proceedings (ISTP CDROM version / ISI Proceedings)• CC Proceedings — Engineering & Physical Sciences
This volume discusses membrane potential imaging in the nervous system and in the heart and modern optical recording technology. Additionally, it covers organic and genetically-encoded voltage-sensitive dyes; membrane potential imaging from individual neurons, brain slices, and brains in vivo; optical imaging of cardiac tissue and arrhythmias; bio-photonics modelling. This is an expanded and fully-updated second edition, reflecting all the recent advances in this field. Twenty chapters, all authored by leading names in the field, are cohesively structured into four sections. The opening section focuses on the history and principles of membrane potential imaging and lends context to the following sections, which examine applications in single neurons, networks, large neuronal populations and the heart. Topics discussed include population membrane potential signals in development of the vertebrate nervous system, use of membrane potential imaging from dendrites and axons, and depth-resolved optical imaging of cardiac activation and repolarization. The final section discusses the potential – and limitations – for new developments in the field, including new technology such as non-linear optics, advanced microscope designs and genetically encoded voltage sensors. Membrane Potential Imaging in the Nervous System and Heart is ideal for neurologists, electro physiologists, cardiologists and those who are interested in the applications and the future of membrane potential imaging.
Uniting the usually distinct areas of particle physics and quantum field theory, gravity and general relativity, this expansive and comprehensive textbook of fundamental and theoretical physics describes the quest to consolidate the basic building blocks of nature, by journeying through contemporary discoveries in the field, and analysing elementary particles and their interactions. Designed for advanced undergraduates and graduate students and abounding in worked examples and detailed derivations, as well as including historical anecdotes and philosophical and methodological perspectives, this textbook provides students with a unified understanding of all matter at the fundamental level. Topics range from gauge principles, particle decay and scattering cross-sections, the Higgs mechanism and mass generation, to spacetime geometries and supersymmetry. By combining historically separate areas of study and presenting them in a logically consistent manner, students will appreciate the underlying similarities and conceptual connections to be made in these fields.
