We propose a generalization of the golden section based on division in mean and extreme ratio. The associated integer sequences have many interesting properties. 1. GENERALIZED GOLDEN RATIOS There have been many generalizations of the number known as golden ratio or golden section, φ = 1+ √ 5 2 . Examples are G.A. Moore’s golden numbers [10] and S. Bradley’s nearly golden sections [5] (see also...

The need for effective facilitation in Group Support Systems (GSS) environments is well documented. Results from recent studies of facilitation in face-to-face electronic meetings have demonstrated that more and different research is required before we have a clearer picture of GSS facilitation. The training of GSS facilitators has been acknowledged as an important issue in GSS research but, up...

Given the difficulty and effort required to confirm candidate causal SNPs detected in genome-wide association studies (GWAS), there is no practical way to definitively filter false positives. Recent advances in algorithmics and statistics have enabled repeated exhaustive search for bivariate features in a practical amount of time using standard computational resources, allowing us to use cross-...

Acknowledgements: This document should be seen as a revised version of the one produced in 2000 in the context of the construction of the 2000 Ghana Poverty Profile. The revisions mainly consist of the inclusion of GLSS 5-specific issues as well as an update of the different statistical tables. Those revisions were done by Harold Coulombe. The authors are grateful to Dr Grace Bediako (GSS), Dr ...

Voting tools in Group Support Systems (GSS) have been considered valuable assets in groups’ decision processes. One important aspect of voting is the method of conducting the vote. Research in Social Choice Theory (SCT) has shown that different voting methods can lead to different voting outcomes. However, SCT seldom addresses how a voting method affects decision making processes. Voting method...
