This volume contains the revised versions of 28 papers presented at the third workshop on Computer Science Logic held in Kaiserslautern, FRG, October 2-6, 1989. These proceedings cover a wide range of topics both from theoretical and applied areas of computer science. More specifically, the papers deal with problems arising at the border of logic and computer science, e.g. in complexity, data base theory, logic programming, artificial intelligece, and temporal logic. The volume should be of interest to all logicians and computer scientists working in the above field.

Currently, the field of information systems technology is rapidly extending into several dimensions. There is the semantic dimension (including object orientation, data deduction and extended knowledge representation schemes), there is improved systems integration, and there are new tools. All these extensions aim to provide semantically richer and better engineered information systems that allow for more adequate and complete representations and thus extend the effective use of database technology to a wider class of applications. Database researchers and developers, whether they are committed to application or to system construction, are convinced that next-generation information system technology will be heavily determined by a handful of new concepts that they have to understand and work out in detail now. This volume concentrates on the following topics: - Extended data types and data models, database programming languages; - Rule-based data deduction, expert systems, knowledge bases; - Object orientation and semantic data modelling; - DB application development, methodologies and tools; - Interface technology, parallelism, interoperability, ...; - New database applications.

A Broken Regiment recounts the tragic history of one of the Civil War's most ill-fated Union military units. Organized in the late summer of 1862, the 16th Connecticut Volunteer Infantry was unprepared for battle a month later, when it entered the fight at Antietam. The results were catastrophic: nearly a quarter of the men were killed or wounded, and Connecticut's 16th panicked and fled the field. In the years that followed, the regiment participated in minor skirmishes before surrendering en masse in North Carolina in 1864. Most of its members spent months in southern prison camps, including the notorious Andersonville stockade, where disease and starvation took the lives of over one hundred members of the unit. The struggles of the 16th led survivors to reflect on the true nature of their military experience during and after the war, and questions of cowardice and courage, patriotism and purpose, were often foremost in their thoughts. Over time, competing stories emerged of who they were, why they endured what they did, and how they should be remembered. By the end of the century, their collective recollections reshaped this troubling and traumatic past, and the "unfortunate regiment" emerged as the "Brave Sixteenth," their individual memories and accounts altered to fit the more heroic contours of the Union victory. The product of over a decade of research, Lesley J. Gordon's A Broken Regiment illuminates this unit's complex history amid the interplay of various, and often competing, voices. The result is a fascinating and heartrending story of one regiment's wartime and postwar struggles.

The European Workshop on Logics in Artificial Intelligence was held at the Centre for Mathematics and Computer Science in Amsterdam, September 10-14, 1990. This volume includes the 29 papers selected and presented at the workshop together with 7 invited papers. The main themes are: - Logic programming and automated theorem proving, - Computational semantics for natural language, - Applications of non-classical logics, - Partial and dynamic logics.

This volume contains the papers presented at the Intemational Conference on Object Oriented Information Systems 00lS'94, held at South Bank University, London, December 19 - 21, 1994. In response to our call for papers, a total 85 papers from 24 different countries were submitted. Each paper was evaluated by at least two Program Committee members and an additional reviewer. Together, we selected 41 papers for presentation at the conference and inclusion in the Proceedings. Also included are the keynote addresses by Peter Gray and Michael Jackson. The other submissions were recommended for presentation in the poster sessions. Peter Gray, our invited speaker, evaluates the problems of object-oriented systems and data independence by looking at how object oriented database applications are failing to perceive its benefits, and instead rely too much on encapsulation. He suggests alternative kinds of object storage to preserve data independence. The second invited speaker, Michael Jackson describes a way of solving problems, by focusing directly on the problems themselves, their components and structures and on the relationships between the problem and the solution method. He discusses a particular view of the role of object-orientation in software development.

TAPSOFT '91 is the Fourth International Joint Conference on Theory and Practice of Software Development. It was held in Brighton, April 8-12, 1991, and was organized by the Department of Computing, Imperial College, London. The proceedings of TAPSOFT '91 are organized into three parts: - Advances in Distributed Computing (ADC) - Colloquium on Trees in Algebra and Programming (CAAP) - Colloquium on Combining Paradigms for Software Development (CCPSD) The proceedings are published in two volumes. The first volume (LNCS, Vol. 493) contains the papers from CAAP. The second volume (LNCS, Vol. 494) contains the papers from the ADC and CCPSD. The ADC talks by distinguished invited speakers surveys current developments in distributed computing, including the integration of different paradigms for concurrency, algebraic, logical and operational foundations, and applications to software engineering and formal methods. The CCPSD papers address aspects of the trend in software enginering towards unification and synthesis combining theory and practice, and merging hitherto diverse approaches.
