Question: What year did Seidman get the role of chief investigator? Passage 1:The Intel Core microarchitecture (previously known as the Next-Generation Micro-Architecture) is a multi-core processor microarchitecture unveiled by Intel in Q1 2006. It is based on the Yonah processor design and can be considered an iteration of the P6 microarchitecture introduced in 1995 with Pentium Pro. High power consumption and heat intensity, the resulting inability to effectively increase clock speed, and other shortcomings such as an inefficient pipeline were the primary reasons why Intel abandoned the NetBurst microarchitecture and switched to a completely different architectural design, delivering high efficiency through a small pipeline rather than high clock speeds. The Core microarchitecture initially did not reached the clock speeds of the NetBurst microarchitecture, even after moving to 45 nm lithography. However after many generations of successor microarchitectures which used Core as their basis (such as Nehalem, Sandy Bridge and more), Intel managed to eventually surpass the clock speeds of Netburst with the Devil's Canyon (Improved version of Haswell) microarchitecture reaching a base frequency of 4 GHz and a maximum tested frequency of 4.4 GHz using 22 nm lithography. 
 Passage 2:In 2000, Parrish was featured in Disney's live-action television film based on the Pinocchio story, Geppetto, portraying the role of Natalie. She then went on to appear as Vanessa in The WB's short-lived sitcom The O'Keefes. Parrish also appeared in shows and made-for-television films on the Disney Channel, and also guest starred in Fox's sitcom The Bernie Mac Show, Nickelodeon's children's comedy-drama series Zoey 101, and Fox's teen drama series The O.C.. Parrish then portrayed Bratz member Jade in the 2007 live-action film Bratz. The role was her first in a motion picture, as well as her first starring role. In May 2007, shortly before the release of Bratz, she was signed to the William Morris Agency. She then landed a recurring role in the NBC supernatural drama series Heroes.
 Passage 3:Seidman was born on August 24, 1955 to a Jewish family, the daughter of Eileen Joan (née Ladenson) and Frank Seidman. She received a B.A. from Miami University and a J.D. from the University of Georgia School of Law. After school, she worked as a senior investigator for the investigation firm, Investigative Group International and later for the People for the American Way. She then worked an assistant to Senator Ted Kennedy and chief investigator for the Senate Labor and Human Resources Committee where she worked against the Robert Bork (1987) and Clarence Thomas (1990) nominations to the U.S. Supreme Court. Nan Aron from Alliance for Justice asserts that she was the one that tipped Seidman off about Thomas' alleged harassment. In 1991, she prepped Anita Hill before she testified.
