What follows is a sampler of work in knowledge acquisition. It comprises three technical papers and six guest editorials. The technical papers give an in-depth look at some of the important issues and current approaches in knowledge acquisition. The editorials were pro duced by authors who were basically invited to sound off. I've tried to group and order the contributions somewhat coherently. The following annotations emphasize the connections among the separate pieces. Buchanan's editorial starts on the theme of "Can machine learning offer anything to expert systems?" He emphasizes the practical goals of knowledge acquisition and the challenge of aiming for them. Lenat's editorial briefly describes experience in the development of CYC that straddles both fields. He outlines a two-phase development that relies on an engineering approach early on and aims for a crossover to more automated techniques as the size of the knowledge base increases. Bareiss, Porter, and Murray give the first technical paper. It comes from a laboratory of machine learning researchers who have taken an interest in supporting the development of knowledge bases, with an emphasis on how development changes with the growth of the knowledge base. The paper describes two systems. The first, Protos, adjusts the training it expects and the assistance it provides as its knowledge grows. The second, KI, is a system that helps integrate knowledge into an already very large knowledge base.

The Metropolitan Museum's preeminent collection of early colonial furniture is expertly documented in this long-awaited publication. It covers the full spectrum of furniture forms made during the 17th and early 18th centuries--from chairs and other seating to tables, boxes, various types of chests and cupboards, and desks. Each of the 141 objects is thoroughly described with detailed information on provenance, construction, condition, inscriptions, dimensions, and materials. Photographed anew in color for this volume, each piece is explicated in terms of the styles and craftsmanship of the period and is evaluated in light of comparative pieces in public and private collections throughout the country. One appendix contains photographic details of construction and decorative elements, and another has drawings of joints and moldings.

DIV The advent of the crossbow more than 2,500 years ago effected dramatic changes for hunters and warriors. For centuries, it was among the most powerful and widely used handheld weapons, and its popularity endures to this day. A Deadly Art presents a lively, accessible survey of the crossbow’s “golden age,” along with detailed descriptions of twenty-four remarkable examples. Beginning in the middle ages, the European aristocracy’s enthusiasm for the crossbow heralded shooting competitions and pageants that featured elaborately decorated weapons bearing elegant embellishments of rare materials and prized artistry. In addition to being highly functional, these weapons were magnificent works of art. A Deadly Art includes fascinating descriptions of crossbows used by Margaret of Savoy and Holy Roman Emperors Maximilian I and Charles V, among others. /div

"In the royal and princely courts of Europe, artworks made of multicolored semiprecious stones were passionately coveted objects. Known as pietre dure, or hardstones, this type of artistic expression includes?paintings in stone,? which were composed of intricately cut separate pieces that were made into magnificent tabetops, cabinets, and wall decorations. Other works included vessels and ornaments carved with virtuosic skill from a single piece of rare and brilliant lapis lazuli, chalcedony, jasper, or similarly prized substance; exquisite objects such as boxes, clocks, and jewelry; and portraits of nobles sculpted in variously colored stones. Derived from ancient Roman decorative stonework, the art of pietre dure was developed in Renaissance Florence, where the manufacture of such objects was enthusiastically sponsored by Medici princes. Ideally suited for ostentatious display, the works sent an unmistakable message of wealth and political might that was understood in centers of power everywhere. From Italy the medium spread across Europeto Prague, Madrid, Naples, Paris, and later Saint Petersburg. Precious and fragile, pietre dure objects are rarely brought together in large numbers. This richly illustrated catalogue contains more than 150 masterworks from across Europe, dating from five centuries, including almost every artistic use of semiprecious stone during this time as well as some of the finest examples of the medium. Eight essays by European and American experts discuss the individualized development of pietre dure in every European region, the latest developments in scholarship, the interrelationships between art and dynastic politics and between cultures, and a variety of techniques used to produce these luxurious masterworks."--Metropolitan Museum of Art website.

This volume contains a selection of refereed and revised papers, originally presented at the 30th Linguistic Symposium on Romance Languages, representing the areas of syntax, semantics, their interfaces, and second language acquisition. The topics addressed include movement (both wh- and head-movement), control, issues of second language acquisition related to the Determiner Phrase, the effect of word order and syntactic simplification in second language acquisition, adverbials, syntactic constraints on access to lexical structure, a semantic characterization of the subjunctive in Spanish, and impersonal constructions and impersonal reflexive pronouns. The papers in this volume not only discuss issues related to most of the major Romance languages (French, Italian, Portuguese, Rumanian and Spanish) and a Portuguese Creole, but also include comparisons with languages from other families (Marathi, Bulgarian, Polish and Slovenian). This collection of papers illustrates the richness in the field of Romance linguistics and the value of cross-linguistic research and multi-modular approaches.

What happens to companies that had been taken over through an LBO; how have they performed since the takeover; how have the communities been affected; what happened to companies that amassed tremendous debt to avoid being taken over? In order to address these questions in this report, case studies were done of the companies that experienced an LBO or a takeover attempt during the mid- to late 1980s. The assessment was based primarily on public documents and financial reports filed by the companies with the SEC.
