There are a number of issues here. First, it is not necessarily a
violation of the code if the name of the sponsor is withheld during the
study. However, there should be some provision made to inform the
participants either at the end of the focus group or the end of the
project. Similarly, it is Marlene's responsibility to clarify the
possible ethical issue prior to starting the research and if the
research violates the code, she is expected not to do it. In both
cases, the code states that checking with an IRB or similar body would
help clarify the issues.
