Als „Vater“ der Ethnomethodologie war Harold Garfinkels übergreifendes Anliegen „the study of the everyday practices used by the ordinary members of society in order to deal with their day-to-day lives”. Seine Herangehensweise und die Konzipierung der Ethnomethodologie entspringen fundamental einer Kritik an Auguste Comtes Individualismus, welche zuerst von Émile Durkheim vorgetragen und von Talcott Parsons weiterentwickelt wurde, welcher schließlich Garfinkels Dissertation an der Universität Harvard betreute. In den folgenden sieben Jahrzehnten wurde die Ethnomethodologie zu einer ebenso einflussreichen wie kontrovers diskutierten Strömung, nicht nur innerhalb der Soziologie, sondern in einer Vielzahl von Wissenschaftszweigen. Die vorliegende Arbeit zeigt, wie der Aufbau eines virtuellen Archivs basierend auf der Sammlung von Unterlagen aus Harold Garfinkels persönlichem Büro einen Beitrag zur Entwicklung einer „Sociological Theory of Information“ in seinem Sinne leistet.

With about 200,000 entries, StarBriefs Plus represents the most comprehensive and accurately validated collection of abbreviations, acronyms, contractions and symbols within astronomy, related space sciences and other related fields. As such, this invaluable reference source (and its companion volume, StarGuides Plus) should be on the reference shelf of every library, organization or individual with any interest in these areas. Besides astronomy and associated space sciences, related fields such as aeronautics, aeronomy, astronautics, atmospheric sciences, chemistry, communications, computer sciences, data processing, education, electronics, engineering, energetics, environment, geodesy, geophysics, information handling, management, mathematics, meteorology, optics, physics, remote sensing, and so on, are also covered when justified. Terms in common use and/or of general interest have also been included where appropriate.

The first two editions of this book have been very well received by the com­ munity, but so many revisions ofthe Maple system have occurred since then that simply reprinting the out-of-stock book would not do anymore. A ma­ jor revision of the book was inevitable, too. The wording "major revision" must be taken seriously because I not only corrected typographical errors, rephrased text fragments, and updated many examples, but I also rewrote complete chapters and added new material. In particular, the chapter on differential equations now discusses Liesymmetry methods, partial differen­ tial equations, and numerical methods. Linear algebra is based throughout the book on the packages LinearAlgebra and VectorCalculus, which re­ place the deprecated package linalg. Maple users are strongly advised to do their work with the new packages. The chapter on simplification has been updated and expanded; it discusses the use of assumptions in more detail now. Last, but not least, a new chapter on Grabner basis theory and the Groebner package in Maple has been added to the book. It includes many applications of Grabner basis theory. Many of the Maple sessions have been rewritten so that they comply with the most recent version of Maple. As a result of all this work, hardly any section in the book has been left untouched. vi Preface to the Third Edition From the Preface of the Second Edition The first edition ofthis book has been very wellreceived by the community.

Interest in statistical methodology is increasing so rapidly in the astronomical community that accessible introductory material in this area is long overdue. This book fills the gap by providing a presentation of the most useful techniques in multivariate statistics. A wide-ranging annotated set of general and astronomical bibliographic references follows each chapter, providing valuable entry-points for research workers in all astronomical sub-disciplines. Although the applications considered focus on astronomy, the algorithms used can be applied to similar problems in other branches of science. Fortran programs are provided for many of the methods described.
