Dear Bob,
I should perhaps have clarified that in the text of which I sent the abstract around yesterday, I formulate at p. 10 (in honour of Bob Ulanowicz) as follows: With the same enthusiasm which Krippendorff (2009a) reports about Ashby (1969), one of us embraced this potentially negative sign in the mutual information in three dimensions as an indicator of potential reduction of uncertainty in Triple-Helix configurations once it was brought to his attention by Robert Ulanowicz, who had used the same indicator in the context of his ascendancy theory in mathematical biology (Ulanowicz, 1986: 143). This same indicator is used across disciplines (see for an overview: Jakulin, 2005) and sometimes called "configurational information," but it has remained controversial because it is poorly understood. As noted, a signed information measure cannot be interpreted in Shannon information theory, whereas alternative frameworks for its appreciation have remained ill-defined (Krippendorff, 1980, 2009a and b). arXiv:1301.6849 <http://arxiv.org/abs/1301.6849> [pdf <http://arxiv.org/pdf/1301.6849> ] Mutual Redundancies in Inter-human Communication Systems: Steps Towards a Calculus of Processing Meaning Does the issue return in the book? Our argument is that this "mutual information" is a redundancy and can then be integrated into the framework of the mathematical theory of communication.

That resulted in the attached paper. Some of you on FIS will receive this email post twice as I do not know who all is on FIS - I am sending this post to all folks that were copied on emails to or from Robert Ulanowicz. I hope you will find time to read my paper and sent me your comments. If you like this paper I have another that I submitted to Zygon that deals with matters spiritual and theological also stimulated by Robert Ulanowicz's A 3rd Window. I would be happy to send it to you. with kind regards to all - Bob Logan
