Call for papers and abstracts
You are invited to submit proposals for symposia, paper sessions, workshops and poster sessions. The deadline for submission of abstracts is December 15, 2007. A second deadline is April 15, 2008. Note, however, that after December 15, 2007 first decisions on acceptance will be made, and sessions will be scheduled. First preference will be given to abstracts submitted by the first deadline.

Symposia
Submitters of Symposium abstracts are kindly requested to give a general description of the Symposium in the main/general description abstract (up to 250 words). After sending the main abstract, you may select, fill in and send the necessary number of sub-abstracts (up to 250 words) for your Symposium.

Workshops
This format is provided for the development of specific skills. In the abstract, please identify the specific skills to be taught and the expected learning outcomes for the participants.

Paper Presentations
Individual papers will be grouped into thematic sessions. Depending on the number of papers, participants will have up to 30 minutes to present their papers, including discussion.

Posters
Each poster will be exhibited for a day or half a day. The posters, exhibited simultaneously, will be grouped into thematic sessions. Authors of posters will be invited to participate in round table discussions regarding their papers.
