"Categorical Perspectives" consists of introductory surveys as well as articles containing original research and complete proofs devoted mainly to the theoretical and foundational developments of category theory and its applications to other fields. A number of articles in the areas of topology, algebra and computer science reflect the varied interests of George Strecker to whom this work is dedicated. Notable also are an exposition of the contributions and importance of George Strecker's research and a survey chapter on general category theory. This work is an excellent reference text for researchers and graduate students in category theory and related areas. Contributors: H.L. Bentley * G. Castellini * R. El Bashir * H. Herrlich * M.

This volume is the result of a symposium titled "Constructivist Approaches to Atypical Development and Developmental Psychopathology." What emerges from the work included here is a record of innovative extensions, refinements, and applications of the concept of constructivism. The chapters not only demonstrate the compatibility of constructivism with investigations of atypicality, but also the generation of a constructivist perspective for a wide array of problems in developmental psychology.

The book collects original research papers on applied categorical structures, most of which have been presented at the North-West European Category Seminar 2003 in Berlin. The spectrum of these mathematical results reflects the varied interests of Horst Herrlich ? one of the leading category theorists of the world ? to whom this volume is dedicated in view of his 65th birthday. The book contains applications of categorical methods in various branches of mathematics such as algebra, analysis, logic and topology, as well as fuzzy structures and computer science. At the end of the book the reader will find a complete list of Horst Herrlich's publications.The proceedings have been selected for coverage in: ? Index to Scientific & Technical Proceedings?

This book contains a selection of original conference papers covering all major fields in the philosophy of science, that have been organized into themes. The first section of this volume begins with the formal philosophy of science, moves on to idealization, representation and explanation and then finishes with realism, anti-realism and special science laws. The second section covers the philosophy of the physical sciences, looking at quantum mechanics, spontaneous symmetry breaking, the philosophy of space and time, linking physics and metaphysics and the philosophy of chemistry. Further themed sections cover the philosophies of the life sciences, the cognitive sciences and the social sciences. Readers will find that this volume provides an excellent overview of the state of the art in the philosophy of science, as practiced in different European countries. ​

A graduate-level textbook that presents basic topology from the perspective of category theory. This graduate-level textbook on topology takes a unique approach: it reintroduces basic, point-set topology from a more modern, categorical perspective. Many graduate students are familiar with the ideas of point-set topology and they are ready to learn something new about them. Teaching the subject using category theory--a contemporary branch of mathematics that provides a way to represent abstract concepts--both deepens students' understanding of elementary topology and lays a solid foundation for future work in advanced topics.

One of the predominant trends of modern society is the pervasive presence of competition. No longer just a function of economic markets or democratic systems, competition has become a favoured tool for governing people and organizations, from the provision of schooling and elder care to the way we consume popular culture. Yet social scientists have played a surprisingly modest role in analysing its implications, as the discussion of competition has largely been confined to its narrow economic meaning. This book opens up competition for the study of social scientists. Its central message is that while competition seems ubiquitous, it should not be taken for granted or be naturalized as an inevitable aspect of human existence. Its emergence, maintenance, and change are based on institutions and organizational efforts, and a central challenge for social science is to learn more about these processes and their outcomes. With the use of a novel definition of competition, more fundamental questions can be addressed than merely whether or not competition works. How is competition constructed - and by whom? Which behaviours result from competition? What are its consequences? Can competition be removed? And, how do these factors vary with the object of competition - be it money, attention, status, or other scarce and desired objects? This book investigates these and more questions in studies of competition among and within schools, universities, multinational corporations, auditors, waste-disposal firms, fashion designers, and more.
