The technological means now exists for approaching the fundamentallimiting scales of solid state electronics in which a single carrier can, in principle, represent a single bit in an information flow. In this light, the prospect of chemically, or biologically, engineered molccular-scale structures which might support information processing functions has enticed workers for many years. The one common factor in all suggested molecular switches, ranging from the experimentally feasible proton-tunneling structure, to natural systems such as the micro-tubule, is that each proposed structure deals with individual information carrying entities. Whereas this future molecular electronics faces enormous technical challenges, the same Iimit is already appearing in existing semiconducting quantum wires and small tunneling structures, both superconducting and normal meta! devices, in which the motion of a single eh arge through the tunneling barrier can produce a sufficient voltage change to cut-off further tunneling current. We may compare the above situation with today's Si microelectronics, where each bit is encoded as a very !arge number, not necessarily fixed, of electrons within acharge pulse. The associated reservoirs and sinks of charge carriers may be profitably tapped and manipulated to proviele macro-currents which can be readily amplified or curtailed. On the other band, modern semiconductor ULSI has progressed by adopting a linear scaling principle to the down-sizing of individual semiconductor devices.

The human race has altered the chemical composition of the atmosphere, as evidenced by the notorious London smog, photochemical air pollution, acid rain, stratospheric ozone depletion, and elevated greenhouse gas concentrations. The aim of this book series is to present invited summaries of important current research on atmospheric chemistry in a changing world. The summaries range from comprehensive scholarly reviews of major subject areas to more narrowly focused accounts of recent advances by individual research groups. The topics are tied to the important societal issues of air quality, stratospheric ozone depletion, acid deposition, the environmental fate of toxics, and climate change. By gathering these new Advances in one series, we aim to catalyze communication among the many researchers who are studying our changing, contemporary atmosphere.

Biblical Foundations of Spirituality invites readers to "touch a finger to the flame" of the Bible by offering guidance on what, how, and why to read Scripture as a source of spiritual nourishment. The second edition builds on Barbara Bowe's acclaimed book with two new chapters by Laurie Brink and John R. Barker introducing key theological concepts and exploring how biblical spirituality was first experienced and expressed in early Christian communities. The book begins by exploring the many meanings of the word "spirituality," then leads readers through the Bible-from Genesis to Revelation-to develop a biblically based spirituality that can serve as a compass in the challenges of life. Updated to reference the latest scholarship, this book helps make the Bible more accessible and shows how it can be relevant to life today. The book stresses the spiritual dimension of biblical figures' search for God and shows how their insights about God-from successes to dead ends-can reflect our contemporary searching and struggles. Biblical Foundations of Spirituality reveals the spiritual wisdom of the Bible, connecting it with everyday life and spirituality. With a chronology, reflection questions, a glossary, and updated notes and bibliography, as well as two new chapters, the second edition of Biblical Foundations of Spirituality is ideal for classroom, parish, or individual reading.

Since the 1980s, the language used around market-based government has muddied its meaning and polarized its proponents and critics, making the topic politicized and controversial. Competition, Choice, and Incentives in Government Programs hopes to reframe competing views of market-based government so it is seen not as an ideology but rather as a fact-based set of approaches for managing government services and programs more efficiently and effectively. Published in cooperation with IBM.

This series presents authoritative invited summaries of research on atmospheric chemistry in a changing world. These range from comprehensive reviews of major subject areas to focused accounts by individual research groups. The topics may include laboratory studies, field measurements, in situ monitoring and remote sensing, studies of composition, chemical modeling, theories of atmospheric chemistry and climate, feedback mechanisms, emissions and deposition, biogeochemical cycles, and the links between atmospheric chemistry and the climate system at large.Volume 2 comprises chapters describing research on multiphase chemistry affecting air quality in China, on multiphase chemistry of organic compounds leading to secondary organic aerosol formation, on biogeochemical cycles involving ammonia, on oxidation of aromatic compounds, on reactions of Criegee intermediates (important in oxidation of alkenes), and on laboratory and field measurements of isotopic fractionation in the atmosphere.
