Agent-based modelling on a computer appears to have a special role to play in the development of social science. It offers a means of discovering general and applicable social theory, and grounding it in precise assumptions and derivations, whilst addressing those elements of individual cognition that are central to human society. However, there are important questions to be asked and difficulties to overcome in achieving this potential. What differentiates agent-based modelling from traditional computer modelling? Which model types should be used under which circumstances? If it is...

After the pioneering works by Robbins {1944, 1945) and Choquet (1955), the notation of a set-valued random variable (called a random closed set in literatures) was systematically introduced by Kendall {1974) and Matheron {1975). It is well known that the theory of set-valued random variables is a natural extension of that of general real-valued random variables or random vectors. However, owing to the topological structure of the space of closed sets and special features of set-theoretic operations ( cf. Beer 27]), set-valued random variables have many special properties. This gives new...

Olof Dahlback's book breaks new ground for the analysis of crime from a rationality perspective by presenting models and methods that go far beyond those with which researchers have hitherto been equipped. The book examines single crimes, individual criminality, and societal crime, and it discusses thoroughly the general decision theoretical presuppositions necessary for analyzing these various types of crime. An expected utility maximization model for a single discrete choice regarding the commission of a crime is the foundation of most of the analyses presented. A version of this model is...

According to Putnam to talk of "facts" without specifying the language to be used is to talk of nothing; "object" itself has many uses and as we creatively invent new uses of words "we find that we can speak of 'objects'that were not 'values of any variable'in 1 any language we previously spoke" . The notion of object becomes, then, like the notion of reference, a sort of open land, an unknown territory. The exploration of this land - pears to be constrained by use and invention. But, we may wonder, is it possible to guide invention and control use? In what way, in particular, is it possible,...

Chapters in Game Theory has been written on the occasion of the 65th birthday of Stef Tijs, who can be regarded as the godfather of game theory in the Netherlands. The contributors all are indebted to Stef Tijs, as former Ph.D. students or otherwise.
The book contains fourteen chapters on a wide range of subjects. Some of these can be considered surveys while other chapters present new results: most contributions can be positioned somewhere in between these categories. The topics covered include: cooperative stochastic games; noncooperative stochastic games; sequencing games;...

The game-theoretic modelling of negotiations has been an active research area for the past five decades, that started with the seminal work by Nobel laureate John Nash in the early 1950s. This book provides a survey of some of the major developments in the field of strategic bargaining models with an emphasize on the role of threats in the negotiation process. Threats are all actions outside the negotiation room that negotiators have ate their disposal and the use of these actions affect the bargaining position of all negotiators. Of course, each negotiator aims to strengthen his own...

The present volume collects some of the talks given at the Bertrand Russell Colloquium on Exact Philosophy, attached to the McGill University Foundations and Philosophy of Science Unit. It also includes a paper, on Bertrand Russell's method of philosophizing, read at the memorial symposium held at Sir Gorge Williams University shortly after the philosopher's death. All the papers appear here for the first time. Unlike many a philosophy of science anthology, this one is not center- ed on the philosophy of physics. In fact the papers deal with conceptual and, in particular, philosophical...

'Human Communication' is a field of interest of enormous breadth, being one which has concerned students of many different disciplines. It spans the imagined 'gap' between the 'arts' and the 'sciences', but it forms no unified academic subject. There is no commonly accepted terminology to cover aU aspects. The eight articles comprising this book have been chosen to illustrate something of the diversity yet, at the same time, to be comprehensible to readers from different academic disciplines. They cannot pretend to cover the whole field Some attempt has been made to present them in an order...

Philosophy of Science deals with the problem, 'What is science?' It seems that the answer to this question can only be found if we have an answer to the question, 'How does science function?' Thus, the study of the methodology of social sciences is a prominent factor in any analysis of these sciences. The history of philosophy shows clearly that the answer to the question, 'How does science function?' was the conditio sine qua non of any kind of philosophy of science, epistemology and even of logic. Aristotle, Hume, Kant, Mill, Russell, to mention a few classical authors, clearly emphasized...
