Combines in one volume Technics and Language and Memory and Rhythms, the cornerstones of Leroi-Gourhan's comprehensive theory of human behavior and cultural development AndrA (c) Leroi-Gourhan (1911-1986) was an anthropologist and paleontologist whose theoretical endeavors extended well beyond those realms to encompass the culture of the twentieth century and its most advanced developments. His bold and coherent revision of both analytic and archaeological methods revolutionized the study of prehistoric culture. His adoption of the structuralist method for the analysis of prehistoric art enabled a radical rethinking and clearer understanding of its nature, with resulting implications for the understanding of the art of our own times, and for a broad range of contemporary issues.Leroi-Gourhan was, for example, concerned with questions of communication, particularly the ways in which new techniques of communication reshape our understanding of language and writing. His work in this field has proved catalytic for the thinking of other major theorists, among them Jacques Derrida. Gesture and Speech combines in one volume Technics and Language and Memory and Rhythms, which are the cornerstones of Leroi-Gourhan's comprehensive theory of human behavior and cultural development. In Technics and Language, Leroi-Gourhan looks at prehistoric technology in relation to the development of cognitive and linguistic faculties, expanding on the cultural ramifications of erect posture, a short face, a free hand during locomotion, and possession of movable implements.Memory and Rhythms approaches its subject from the standpoints of sociology and aesthetics. Here Leroi-Gourhan addresses the problems of instinct and intelligence. He defines the relationship between aesthetic behavior, on the one hand, and species attitudes and the personalization of ethnic groups, on the other, and undertakes a sweeping aesthetic analysis from visceral perception to figurative art, including a discussion of the "language of forms" that makes figurative art an abstract expression of language.

El presente libro no es una simple reedicion de La Prehistoria de Andre Leroi-Gourhan, sino una obra completamente renovada. A partir de entonces, la investigacion, y junto con ellos nuestros conocimientos, han progresado considerablemente. Asi, mas que al antiguo plano cronologico (Paleolitico inferior, medio y superior, Mesolitico y Neolitico), se ha dado preferencia a un nuevo planteamiento regional que nos da mejor cuenta de la diversidad de la evolucion de las culturas humanas.

This book contains the proceedings of the AMS Special Session, in honor of S. K. Jain's 80th birthday, on Categorical, Homological and Combinatorial Methods in Algebra held from March 16-18, 2018, at Ohio State University, Columbus, Ohio. The articles contained in this volume aim to showcase the current state of art in categorical, homological and combinatorial aspects of algebra.

This book contains the proceedings of the Fifth International Conference on Noncommutative Rings and their Applications, held from June 12-15, 2017, at the University of Artois, Lens, France. The papers are related to noncommutative rings, covering topics such as: ring theory, with both the elementwise and more structural approaches developed; module theory with popular topics such as automorphism invariance, almost injectivity, ADS, and extending modules; and coding theory, both the theoretical aspects such as the extension theorem and the more applied ones such as Construction A or Reed-Muller codes. Classical topics like enveloping skewfields, weak Hopf algebras, and tropical algebras are also presented.
