Pellston and Technical Workshops
Share |

SETAC is esteemed for its preeminent workshops, in particular those known as Pellston Workshops in recognition of the inaugural 1970s workshop that brought together leading scientists from academia, business, and governments around the world. Decades later, SETAC has held more than 50 Pellstons, each focusing on a relevant environmental topic with proceedings published as a peer-reviewed report, book or journal article compilation. In addition, the Society holds highly topical technical workshops and symposia in a variety of locations.

Deciding if a SETAC Workshop should be a Pellston Workshop® or a Technical Workshop

SETAC organizes two distinct types or levels of workshop. Pellston Workshops are the premier type of workshop developed by SETAC back in 1977 (actually 2 years before SETAC was chartered). The term “Pellston Workshop”, the organizing process, and the workshop format or structure are registered trademarks of SETAC.

Technical workshops on the other hand, while having some characteristics in common with Pellston Workshops, are less rigorous events, allowing a shorter planning horizon and having other less demanding attributes, making them easier to organize and carry out, although typically less impactful. Following is a list of the primary characteristics of each workshop type along with commentary to help you, as a potential proponent, decide which one better suits the nature of the scientific topic and the resources to conduct a workshop to appropriately address it.

It is also worth noting that there are various “flavors” of technical workshops, depending on the degree of involvement of SETAC (and its members) in arranging and conducting the workshop. In short, a Type 1 workshop is solely organized and carried out by SETAC, a Type 2 workshop entails a co-organizer or co-organizers, and a Type 3 workshop is one where SETAC endorses the workshop being organized by another organization and may or may not have a representative on the steering committee of the workshop.
