Alan, Count of Nantes (988–90): Alan (sometimes Alan II of Brittany or Alan III of Nantes) (born after 981, died 990) was the only known son of Guerech, Duke of Brittany, and Aremberg.  With his mother he founded the castle of Ancenis around 987, according to the "Chronicle of Nantes".  In 988, he succeeded his father as Count of Nantes and perhaps nominal Duke of Brittany, after his father was murdered by Count Conan I of Rennes.  The following two years were marked by endless warfare between Rennes and Nantes.  In 990, Alan died, either of an illness or else killed by Conan, who took Nantes and had himself proclaimed Duke of Brittany by the bishop of Nantes, Orscand de Vannes.  Alan is generally not counted among the dukes of Brittany and, as such, his ordinal number conflicts with the later Duke Alan III of Brittany.

Information source: An information source is a person, thing, or place from which information comes, arises, or is obtained.  That source might then inform a person about something or provide knowledge about it.  Information sources are divided into separate distinct categories, primary, secondary, tertiary, and so on.

Information cascade: An information (or informational) cascade occurs when a person observes the actions of others and then – despite possible contradictions in his/her own private information signals – engages in the same acts.  A cascade develops when people "abandon their own information in favor of inferences based on earlier people's actions".  Information cascades provide an explanation for how such situations can occur, how likely they are to cascade incorrect information or actions, how such behavior may arise and desist rapidly, and how effective attempts to originate a cascade tend to be under different conditions.  By explaining all of these things, the original Independent Cascade model sought to improve on previous models that were unable to explain cascades of irrational behavior, a cascade's fragility, or the short-lived nature of certain cascades.
