You already received a reply for this, but the first e-mail went to the list 
so, we thought replying to the list would be appropriate. Your questions are 
answered below.

Again, KDE users, please go to 


and fill out survey if you haven't done so

Corrado, thanks for the thoughtful comments and questions. Here are some

This is an academic research that could "potentially" lead to publications. 
There is no guarantee. There are several factors affecting the significance 
of findings. Dissertation? At this stage no. We have some Ph.D. students that 
can consider this area though.

No funding sources except the State of Maryland through University System of 
Maryland (normal university resources equipment, etc.). There is no special 
grant from any company, governmental agency, profit or non-profit 
organization. There is definitely "NO" vested interest.

As you said, we are checking for reliability, dependability, correctness, 
performance, and correct operation aspects of quality. There are of course 
other aspects, for example usability.The scope has to be limited. Regarding 
to the focus on the negative aspects, we simply do not agree, there were 
options in each question to accommodate a wide range of users from extremely 
satisfied to exteremel unsatisfied.
