Papers and investigation reports are two styles. A "paper" refers to an article devoted to discussing or studying a certain problem, and an "investigation report" refers to a "on-site" written report, including the designated object of investigation, records of judgments and reactions to events, etc. There are "arguments" and "arguments" in the style of the paper, and "chronicle" in the style of the investigation report.
