University of Arizona

University and federal policies and regulations may apply if you perform empirical research at the University of Arizona.Research directly involving human subjects will most likely require compliance with some portion of 45 CFR 46. The National Institutes of Health (NIH) has a complete set of regulations implicated in any research involving human subjects. ( See section 46.101(b)to determine if your research requires review by an Institutional Review Board (IRB) or if it qualifies as an exception. The UA has four such IRBs (IRB1, IRB2, IRB3 and IRB4). IRB2 relates to social and behavioral sciences, a broad subject area which may well describe much research in the "law and__" categories.

There is a Manual for Researchers as well as a Quick Guide to Necessary Approvals on the IRB web page ( ).

For a fairly comprehensive collection of UA links, check the Resources for Researchers page ( ).

Other useful topics and pages include:

Office for the Responsible Conduct of Research(ORCR)

-Statistical Tools
University Information Technology Services (UITS) offers support for several statistical software packages including SPSS, SAS, Minitab, S-Plus and others.

Call UITS for more info ( 626-TECH (8324)).
