Equivalence and Duality for Module Categories with Tilting and Cotilting for Rings

By: Robert R. Colby,Kent R. Fuller

This book provides a unified approach to much of the theories of equivalence and duality between categories of modules that has transpired over the last 45 years. In particular, during the past dozen or so years many authors (including the authors of this book) have investigated relationships between categories of modules over a pair of rings that are induced by both covariant and contravariant representable functors, in particular by tilting and cotilting theories. By here collecting and unifying the basic results of these investigations with innovative and easily understandable proofs, the authors' aim is to provide an aid to further research in this central topic in abstract algebra, and a reference for all whose research lies in this field.

Introduction to Qualitative Research Methods

A Guidebook and Resource

By: Steven J. Taylor,Robert Bogdan,Marjorie DeVault

An informative real-world guide to studying the "why" of human behavior Introduction to Qualitative Research Methods is a practical, comprehensive guide to the collection and presentation of qualitative data. Unique in the market, this book describes the entire research process — from design through writing — illustrated by examples of real, complete qualitative work that clearly demonstrates how methods are used in actual practice. This updated fourth edition includes all new case studies, with additional coverage of mixed methods, non-sociological settings, funding, and a sample interview guide. The studies profiled are accompanied by observation field notes, and the text includes additional readings for both students and instructors. More than just theory, this guide is designed to give you a real-world practitioner's view of how qualitative research is handled every step of the way. Many different disciplines rely on qualitative research as a method of inquiry, to gain an in-depth understanding of human behavior and the governing forces behind it. Qualitative research asks "why" and "how," and the data is frequently complex and difficult to measure. This book shows you how to effectively handle qualitative work, regardless of where it's being applied. Understand the strengths and limitations of qualitative data Learn how experts work around common methodological issues Compare actual field notes to the qualitative studies they generated Examine the full range of qualitative methods throughout the research process Whether you're studying sociology, psychology, marketing, or any number of other fields, especially in the social and behavioral sciences, human behavior is the central concern of your work. So what drives human behavior? That's what qualitative research helps to explain. Introduction to Qualitative Research Methods gives you the foundation you need to begin seeking answers.

American Automobiles of the Brass Era

Essential Specifications of 4,000+ Gasoline Powered Passenger Cars, 1906-1915, with a Statistical and Historical Overview

By: Robert D. Dluhy

From Abbott-Detroit to Zip, this unique reference book documents American gasoline-powered automobiles manufactured for the model years 1906 through 1915, the Brass Era. In these explosive early years of automotive history, a vast number of manufacturers--most of which failed within two years--produced a range of cars whose sheer diversity is unmatched in later times. The short corporate lifespans and constant change throughout the industry left a fragmented historical record, with data about specific models scarce and scattered in later sources. Here the basic facts of 4,000+ cars, painstakingly researched in all available period sources, are collected and trends of the era are analyzed.
