This book explores cases and presents conceptual approaches for systemics of incompleteness and quasi-systems. The book argues that classical models of systemics attempt to represent phenomena “in total.” The main concern is that such an approach is doomed to fail, as they are unable to represent crucial properties. For example with emergence, the whole is greater than the sum of its parts. In principle, it is a matter of non-complex phenomena, to be considered using the concepts of the First Systemics. These First Systemics are replaced with Second Systemics, or more precisely, quasi-systems. Quasi-systems refer to coping with continuous change, for example, structural changes and forms of system collapse. Quasiness also concerns modelling approaches such as network models, in this case called quasinetworks. The focus is on the transient, on multiplicity and coherence which guarantee consistency. Furthermore, the chapters consider how theoretical incompleteness, incomplete modelling, i.e., not exhausted by using individual models, of processes and phenomena should be explored as a conceptual coexistence of different approaches. This is not so much with the purpose of exhausting, but to conceptually represent the structural dynamics of becoming, already considered, for instance, through the use of uncertainty and complementarity principles in physics without referring here to quantum physics. Many approaches used today to deal with social systems are still those of the industrial society. The availability of modern, effective theoretical approaches is crucial for the economy of today's society in order to deal with contexts which owe their complexity. It is a matter of developing knowledge for the current knowledge, information or post-industrial society. This book, based on papers from the Seventh National Conference of the Italian Systems Society, is devoted to furthering systemics research within this context. weiterlesen
