From these query plans it looks like you could benefit from an index like this (if I inferred your DB schema right).
The short plan uses HashJoin and clustered index scans on PK_CALL. The long plan uses NestedLoops and repeated seeks in UK_Pair_.... Most likely the cardinality estimates for '12, 2009, 2009' rule out HashJoin due to insufficient system memory, so you end up with a worse plan (despite the seeks instead of scans). Probably company_id 12 has way more customers than company_id 8.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
