Alonzo Church was undeniably one ofthe intellectual giants of theTwenti- eth Century . These articles are dedicated to his memory and illustrate the tremendous importance his ideas have had in logic , mathematics, comput er science and philosophy . Discussions of some of thesevarious contributions have appeared in The Bulletin of Symbolic Logic, and th e interested reader is invited to seek details there . Here we justtry to give somegener al sense of the scope, depth,and value of his work. Church is perhaps best known for the theorem , appropriately called " C h u r c h ' s Theorem ", that there is no decision procedure forthelogical valid- ity of formulas first-order of logic .

What Church proved precisely is that there is no lambda-definable function that can i n every case providethe right answer , ' y e s ' or ' n o', tothe question of whether or not any arbitrarily given formula is valid .

From Information Literacy to Social Epistemology: Insights from Psychology focuses on information and the ways in which information literacy relates to critical thinking in education, the workplace, and in our social life. The broad context for our interest is the development in internet technologies often characterised by terms like the 'digital age', leading to questions of digital participation, digital divides, and the role of thinking in the information society. In short, to what extent is the 'digital age' engendering changes in learning directed towards the better use of information, and in addition, encouraging or even requiring improvements in critical thinking?

Pediatric Anesthesiology: A Comprehensive Board Review is a high-yield, streamlined study aid. It contains more than 800, realistic, multiple-choice questions tailored to the keywords in the outline of the Pediatric Anesthesiology Certification Examination published by the American Board of Anesthesiology (ABA). To maximize reading efficiency, annotated answers are followed by bulleted key facts and key references. With this book as guide, readers will be able to efficiently prepare for the written primary certification pediatric anesthesiology board exam.

The fragmenting of habitats is endangering animal populations and degrading or destroying many plant populations throughout the world. To address this problem, conservationists have increasingly turned to biological corridors, areas of land set aside to facilitate the movement of species and ecological processes. However, while hundreds of corridor initiatives are under way worldwide, there is little practical information to guide their design, location, and management. "Applying Nature's Design" offers a comprehensive overview of current knowledge on corridors, their design, and their implementation. Anthony B. Anderson and Clinton N. Jenkins examine a variety of conceptual and practical issues associated with corridors and provide detailed case studies from around the world. Their work considers how to manage and govern corridors, how to build support among various interest groups for corridors, and the obstacles to implementation. In addition to assessing various environmental and ecological challenges, the authors are the first to consider the importance of socioeconomic and political issues in creating and maintaining corridors.

What would Latrina Emerson, unassuming librarian and church organist, have in common with an agnostic physicist and a bunch of occultists over 2000 miles away? Absolutely nothing if she could help it. Some not-so-benevolent "Forces of Light", alas, won't let her help it. She's part of their plan save their credibility after some recent embarrassments (Y2K failing to end the world on prophetic schedule, increasing distrust of authority, etc) and shut up those smart alecks in the Forces of Darkness. But the Forces of Darkness have never followed the Light's rules-like the ones that say they have to be totally evil or always lose in the end-and they're not about to start now. A faction of Hell, in fact, has decided that despite religious and philosophical differences, Latrina is too decent a person to be martyred "for the greater good". Warning her, however, gets a bit tricky. And the real wild card may be Latrina herself, who may not be as "manageable" as the Powers-That-Only-Think-They-Be would like.
