Todd Kelman (born January 5, 1975) is a Canadian retired ice hockey defenceman who is currently the General Manager of the Cardiff Devils of the Elite Ice Hockey League, having been an original member of the first Giants squad that played in the old Ice Hockey Superleague in the 2000–01 season.
 He won the Superleague title twice, once with the Giants in 2001–02 (a mere one season after the team was founded) and previously with the Bracknell Bees two seasons earlier in 1999–00.
 He also won the Superleague Playoff Championship and the Elite League with the Giants in 2002–03 and 2005–06 respectively.
 During his tenure at the Giants, 'The Killer' became a huge favourite amongst the fans for his offensive style of play that created goals for the Giants as well as his strong defensive style and solid penalty killing.
 In seven seasons he played 366 games, more than any other player in Giants history.
 He is also the leading points scoring defenceman in Giants history with 67 goals and 122 assists for 189 points.
 At the end of the 2006–07 season, Kelman retired as a player and began his new role as General Manager.
 He did however play 14 more games for the Giants during the 2007–08 season to cover for the injured Roman Gavalier.

Nur ad-Dīn Abd ar-Rahmān Jāmī (Persian: نورالدین عبدالرحمن جامی‎ ‎ ) also known as Mawlanā Nūr al-Dīn 'Abd al-Rahmān or Abd-Al-Rahmān Nur-Al-Din Muhammad Dashti, or simply as Jami or DJāmī and in Turkey as Molla Cami (7 November 1414 – 9 November 1492), was a Persian poet who is known for his achievements as a prolific scholar and writer of mystical Sufi literature.
 He was primarily a prominent poet-theologian of the school of Ibn Arabi and a Khwājagānī Sũfī, recognized for his eloquence and for his analysis of the metaphysics of mercy.
 His most famous poetic works are "Haft Awrang, Tuhfat al-Ahrar, Layla wa -Majnun, Fatihat al-Shabab, Lawa'ih, Al-Durrah al-Fakhirah."
Jan Maroši (born 4 November 1965) is a Czech former football player.
 He made two international appearances for the Czechoslovakia national football team and is also known for having scored directly from a corner for Sigma Olomouc in a 1992–93 UEFA Cup match against Juventus.
 He made a total of 366 top flight appearances spanning the end of the Czechoslovak First League and the beginning of the Gambrinus liga, scoring 67 goals.
 In 2006 Maroši was ranked 15th on the list of players with most appearances in the Czech and/or Czechoslovak top flight since the Czechoslovak First League began in 1925.
Ubaoner is the name of a fictitious ancient Egyptian magician appearing in the second chapter of a story told in the legendary "Westcar Papyrus."
 He is said to have worked wonders during the reign of king (pharaoh) Nebka (3rd dynasty).
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.
Abuzar Buzjani (also spelled "Abudarr Buzjani", in Persian:ابوذر بوزجانی - died 977 or 978) was a Persian poet and Sufi shaikh contemporary with Sebüktigin, the founder of the Ghaznavid Empire in ancient Iran.
 Abūzar was born and lived in Būzǰān.
 According to Jami he worked wonders, and died in 366-67/977.
 He is not discussed in other sources.
 Two Persian and one Arabic bayt are the only quotations from his works remaining.
Dedi (also Djedi or Djedi of Djed-Sneferu) is the name of a fictional ancient Egyptian magician appearing in the fourth chapter of a story told in the legendary "Westcar Papyrus."
 He is said to have worked wonders during the reign of king (pharaoh) Khufu (4th Dynasty).
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.
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.
