The title of the following paper sounds inviting:

@INPROCEEDINGS{richardson:aspects,
AUTHOR = "Joel Richardson and Peter Schwarz",
TITLE = "Aspects: extending objects to support multiple, independent roles",
BOOKTITLE = sigmod,
YEAR = "1991",
ADDRESS = "",
PAGES = "298-307",
EDITOR = "",
PUBLISHER = "ACM Press"
}

from IBM Almaden Research Center.

This paper seems to be a precursor of subject-oriented
programming. 

Although it uses the word "aspect", it does not seem to address
the issues of AOP: controlling tangling of code.
