Describes TAXACOM, an online service of the Clinton Herbarium of the Buffalo Museum of Science in New York. Discusses "Flora Online" which is the first electronic serial to receive a number from the Library of Congress and a Latin translation service for biologists needing help composing Latin descriptions of new taxa. (TW)

Discusses the need to take into account the effects of arrested fractional crystallization in the petrographic classification of volcanic rocks containing plagioclase phenocrysts. Describes the development and use of a computer program to accomplish this task graphically. (TW)

Supports the claim that aspect in English and written Arabic is a function of a variety of sentential elements including verb form, verb class, and adverbials. The two languages are basically similar in regard to two universal aspectual distinctions: syntactic categories and semantic categories. (TR)

Analyzes the music preference structure of college students based on responses to a variety of music use and preference measures. Finds that the underlying structure of music preference is multivariate and that there are crucial differences between males and females in terms of their "mapping" of music types. (MS)

A dialect survey of the Penghu Islands concluded that the Penghu dialects belong to the Southern Min; variation within the dialects is considerable in terms of changed tones, certain finals, and some lexical items; and the Penghu dialects can be further divided into two large groups. (Author/CB)

Description of the International Nuclear Information System includes its history, organizational structure, subject classification scheme, thesaurus, input standards, and various products and services generated by the system. Appendices provide a list of participating countries, subjects covered by the system, and a sample output record.…

Describes three principal types of embedded training: help systems, simulations, and intelligent tutors. Implications of designing and implementing embedded training are discussed in terms of a set of propositions about the use of computers for learning. (Author/MBR)

Data on state aid to higher education is compiled in a variety of ways, using a variety of classification and and analysis methods, but can be misleading or misused and cause bitter political disputes about the strength of state support. (MSE)

Provides a framework for understanding the concept of validity and how it applies to simulation research. Extant tests of validity are discussed in terms of this framework, and a general schema for testing validity is proposed. (MBR)

Reports a study of native Spanish speakers' acquisition of the ability to discriminate lexically in English between similar items with different characteristics. The study also examined the role of first-language interference in the process. (MSE)

This study evaluated the diagnostic validity of a task measuring abstract categorization ability in learning disabled (LD) and non-LD children. Data showed that the component of abstract category knowledge that best disciminates LD children from non-LD, is the knowledge of how members of abstract categories differ from each other. (Author/JAZ)

Examines relationships between the two major components of computer simulations, the computer and participants; highlights major differences between computer-assisted, computer-based, and computer-controlled simulations; and describes three computer-assisted simulations to illustrate the interdependence of the major components.
