Tell me the themes of Marek Siudym's journals.
select t3.theme from journal_committee as t1 join editor as t2 on t1.editor_id = t2.editor_id join journal as t3 on t1.journal_id = t3.journal_id where t2.name = "Marek Siudym"
Okay, tell me the date of the journal with theme "at Jacksonville Jaguars".
select date from journal where theme = "at jacksonville Jaguars"
list the date, theme and sales of the journal which did not have any of the listed editors serving on committee.
select date, theme, sales from journal except select t1.date, t1.theme, t1.sales from journal as t1 join journal_committee as t2 on t1.journal_id = t2.journal_id
