conduct

The manner in which a person behaves, especially in a particular place or situation, often implying a standard of acceptable or appropriate behavior. It can also refer to the way in which an activity is managed or carried out. While Japanese has words for 'behavior' (行動, 振る舞い) or 'management' (管理), 'conduct' as a noun often encapsulates a more formal assessment or expectation of how one should act, or the process of directing something, which isn't always captured by a single direct equivalent and often requires context or a more elaborate phrase in Japanese to convey the full nuance.
