A Team-Formation Algorithm for Faultline Minimization [article]

Sanaz Bahargam, Behzad Golshan, Theodoros Lappas, Evimaria Terzi
2018 pre-print
By introducing faultlines to the team-formation literature, our work creates exciting opportunities for algorithmic work on faultline optimization, as well as on work that combines and studies the connection  ...  In this work, we meet this challenge with a new measure that can be efficiently used for both faultline measurement and minimization.  ...  Similarly, a team formation algorithm has to carefully balance the two states of homogeneity and diversity within a team in order to achieve a low potential for faultlines.  ...

How attitude certainty tempers the effects of faultlines in demographically diverse teams

André Grow, Andreas Flache
2011 Computational and mathematical organization theory  
A strong faultline splits a team into internally homogeneous but mutually dissimilar subgroups based on demographic characteristics.  ...  Computational experiments suggest a moderation effect. Demographic faultlines only affect team cohesion if attitude certainty is low. We discuss implications for future research. .  ...  gratefully acknowledges partial financial support during his work on this article by the German Academic Exchange Service (Deutscher Akademischer Austausch Dienst) with means from the Akzo-Nobel Trust for  ...

Regional scale analysis of landform configuration with base-level maps

C. H. Grohmann, C. Riccomini, M. A. C. Chamani
2011 Hydrology and Earth System Sciences Discussions  
Base-level maps (or "isobase maps", as originally defined by Filosofov, 1960), express a relationship between valley order and topography.  ...  The base-level map can be seen as a "simplified" version of the original topographic surface, from which was removed the "noise" of the low-order streams erosion.  ...  Drainages were extracted using an A T least-cost search algorithm designed to minimize the impact of DEM data errors (Ehlschlaeger, 1989) .  ...
