646 LANGUAGE, VOLUME 67, NUMBER 3 (1991) York Academy of Sciences 583.) New York: The New York Academy of Sciences, 1990. Pp. 235. Cloth $59.00. This book contains eleven papers, selected for publication from among presentations made at meetings of the Linguistics Section of the New York Academy of Sciences from 1984 to 1986. Part 1 (15-92) focuses on the uses of linguistics in the study of society and social interaction . Deborah Tannen suggests that 'conversation and literary discourse both can be understood in terms of their use of coherence conventions which amount to a system of aesthetics or poetics' (30). She presents a useful overview of relevant literature and then shows, using data from a conversation, how repetitions serve as dynamics by which conversations achieve an aesthetic effect. William A. Stewart's contribution is a study of a breakdown in black-white communication. He finds that the source of the breakdown is masked by the deceptive surface similarities between mainstream English and Black English Vernacular. Stewart, the author of the earlier terms basilect and ACROLECT. introduces here the terms xenolect and mimolect. used as in the sentence , 'If pidgin and creóle languages are xenolects , then decreolizing or decreolized varieties are likely to be mimolects' (38). Edward Bendix demonstrates how Puerto Rican racial terms such as hispano, negro, moreno, and bianco can have different meanings in different constructions. In the last paper of Part I, Ana Celia Zentella urges integrating qualitative and quantitative methods in the study of bilingual code-switching, and applies the framework to the speech of Puerto Rican children in New York City. The three papers in Part II (93-142) deal with the uses oflinguistics in studying the acquisition of communicative competence. Katherine Nelson examines language development in context and concludes that, 'unless the context itself is well-understood, language cannot be understood within it' ( 107). Jennifer Ryan Hsu & Helen Smith Cairns attempt to answer the question of how children learn to interpret pronominal reference. In a short paper dealing with aspects of communicative development in physically handicapped toddlers, Gail A. Wasserman & Rhianon Allen report that, while language difficulties are most severe in children with oral clefts and multiple anomalies, children born prematurely and those with other physical anomalies also experience difficulties in language acquisition. Language delays after the age of three are more strongly associated with family background. Part III (143-79) deals with the uses of linguistics in computer analysis of information. In the first of two papers, D. Terence Lanoendoen & Yedidyah Langsam propose a parenthesis-free method of representing grammatical structures; such a method permits the class corresponding to the acceptable expressions of a natural language to constitute a regular set. Naomi Sager then explains how regularities of language usage within a sublanguage are used in computerized information analysis of free-text input. Part IV (181-234) shows how linguistics is applied in comparative approaches. Penny Willis discusses the initial consonant mutations in the Brythonic Celtic languages, and Franklin C. Southworth makes use of linguistic , sociological, archaeological, geographical , and biological evidence to reconstruct prehistoric South Asian language contact. Well printed and free of misprints, the book is a technical but useful and informed contribution to the field of applied linguistics.

Paper $11.95. This volume comprises a collection of fifteen papers presented at the Seventh Conference on El español en los Estados Unidos, held in October 1986 at the University of New Mexico, Albuquerque. Six papers are in Spanish. As the title suggests, the territory covered is extensive, both geographically and topically, and the editor helpfully segments it into four more manageable subareas, which are preceded by his terse introduction . Two papers in the section on 'Language structure and variation' are dialectological studies, and three examine language maintenance. June A. Jaramillo concludes that prescriptive norms continue to govern /// and Usted; both Manuel Gutiérrez and Francisco Ocampo BOOK NOTICES 647 find the subjunctive mood beginning to fall by the linguistic wayside. Two papers in the section 'Language use' concern code-switching between Spanish and...
