In some fashion, yes. Many schools have an honor code specifically condemning acts such as plagiarism, but copyright infringement--being a violation of federal law--should carry some sort of penalty as well.
That being said, many scholarly uses are addressed by provisions such as the US's fair use clause, 17USC107; many acts that would be considered infringement in the "real world" are allowable in academia.

It's not illegal to get a copyright. It's illegal to break copyright laws. People work hard on something and get it copyrighted, so it's unfair if you use a copy of it, claim it for yourself, or use it when you aren't permitted. This includes applications like LimeWire, which should be illegal.
Contact the copyright owner, or his/her agent.

The word Copyright should always be capitalized. It is a specific name for a specific thing.
