Frontiers in System Research - Böcker

While general systems research has had a considerable impact on research in the social sciences, this impact has been mainly conceptual and has not served to provide the operational and methodological aids for research which are possible. In addition, many of those systems-oriented directions and results which do impact social science research have developed inde­ pendently and in piecemeal fashion in recent decades. The main develop­ ment of this book is a cohesive framework within which to integrate results of general systems research and which provides a means for the organiza­ tion of data and observations - and operational procedures by which to proceed - in the investigation and study of social and socio-technical systems. The book systematically develops in the first five chapters ail of the basic concepts and aspects which make up the framework, showing wherever possible the main sources of these concepts and placing them in historical perspective. The developments of the first five chapters are pulled together and integrated, in the last chapter, into a conceptual and operational general systems problem solving framework which extends the investiga­ tive capabilities of researchers of specific systems. The last chapter also contains an example of an overall investigation which utilizes the frame­ work and which proceeds from system definition through the derivation of explanatory knowledge regarding the object system and which illustrates in detail most of the concepts and elements of the framework.

From the beginning, the systems research movement has shown a high potential for offering a conceptual framework for the understanding of social systems. Much of this potential has been realized, but a major gap remains with regard to operational investigative aids. Developments of the last ten years with a method­ ological orientation and emphasis seem finally to be filling this gap. The purpose of this book is to describe the most advanced of these developments and to make them available to a wider audience. The emphasis is on developments that are primarily oriented toward interaction with expertise in the social sciences and that thus hold the most promise for social systems investigation. In particu­ lar, attempts have been made to provide substantiation and illustration of three main points: (1) the common motivation and essential integrability that systems research provides for developments and considerations along a very broad spec­ trum of interests; (2) the very diverse nature of the types and forms of considera­ tions that may be meaningfully integrated; and (3) the operational and usable nature that developments in systems methodology represent for research in the social sciences. The book is divided into three parts with a generally increasing degree of specificity. The first part (Chapters 1, 2, and 3) deals with foundational issues associated with modeling and methodology as areas worthy of study in their ix X PREFACE own right.

In today's social and behavioral sciences, the complexity of many problems requires the development of a number of highly specialized disciplines. However, the cost of such development is the obscuring of the relationships between these disciplines. This dilemma calls for a "mixed strategy" that combines the advantages of specialization with those of a unified viewpoint. The purpose of this book is to provide the connective tissue that is needed to obtain an overall view. The principles of general system theory naturally lead to a framework that includes many known models and content areas; our intention is to strike a balance between generality and plain usefulness. The first part of this book introduces a social system as a network of inter­ acting decision makers. This general framework allows a classification of a num­ ber of more specific structures, which include autocratic and democratic systems, systems with collective and individual decision making, and systems with and without coalitions. In the second part, various psychological schools are seen as specific instances of a general paradigm, which is consequently a point of departure for a taxon­ omy of learning systems. For a full understanding of this matter, we recommend a careful study of the first four chapters as an introduction to the concepts elaborated in the second part of the book. ix PREFACE x Though the subject matter has a formal background, it does not require a mathematical knowledge in depth; familiarity with elementary probability theory and linear algebra is enough.
