The Research Act: A Theoretical Introduction to Sociological Methods

At once a unique textbook for methods courses and a major contribution to sociological theory, this book teaches students the principles of research and to construct and test theories. It brings coherence to the study of methods by presenting four major approaches to experimentation: survey research, participant observation, life histories, and unobtrusive measures from a single theoretical point of view, symbolic interaction. It demonstrates the need for a synthesis between theory and methods, and shows different methods limit and aff ect research results.Denzin's argues that no single method, theory, or observer can capture all that is relevant or important in reality. He argues for the use of triangulation and for a view of theory and methods as concept sensitizers. His approach enables sociologists to acquire specifi c facts about a particular situation while simultaneously elevating these to the level of shared meaning.The author shows students to proceed with research, bringing sharply into focus the possibilities and their limitations. Since his view is integrated rather than eclectic, this is much more than a how to do it manual. Denzin points out aspects of research that fall outside the scope of a given method yet aff ect results, and emphasizes the need to employ several methods to cross-check each other. The Research Act covers all the content of conventional methods courses. The presentation is exciting and imaginative, and provides a thorough review of major sociological methods, a cogent statement about approaches to sociological inquiry, and a source from which a understanding of the problems of research can be derived.

Photographic Instrumentation at the Air Proving Ground Center

Precise spatial position of airborne test objects such as rockets, bombs and missiles is recorded photographically on the Air Force Armament Center test ranges. The instrumentation employed, the use of triangulation in determining spatial position and the accuracies obtained are discussed.

Über die kombinatorische und kontinuumsmässige Definition der Überschneidungszahl zweier geschlossener Kurven auf einer Fläche

The characteristic of two closed curves on an oriented surface is, roughly speaking, the algebraic sum of their intersections, counting a crossing from left to right as +1, a crossing in the opposite sense as −1. To make this definition precise, combinatorial topology replaces the surface by an aggregate of 0-, 1- and 2-cells and first assumes one curve to be a chain (joining the 0-cells), the other to be a co-chain (joining the 2-cells). The idea of homology (as defined by means of ‘integral functions’) and the law of antisymmetry then serve to pass from these specialized to arbitrary curves. This definition is here contrasted with another that arose from ‘topologizing’ the procedure by which the author in hisIdee der Riemannschen Flache (1913) constructed the Abelian integrals of the first kind: it makes no use of triangulation, but instead of the coverage of the surface by neighborhoods and their topological mapping onto circular disks. Finally the paper indicates the steps by which one proves the coincidence of both definitions.
