Technocratic and design stances toward communication expertise: how GDSS facilitators understand their work

This study investigates the shared, and often unstated, premises that frame the expert communication servicing of meeting facilitators who implement group decision support systems (GDSS). Nine premises about facilitating communication were reconstructed from the way practitioners use the concept "process" to describe the expert servicing they perform. The premises reveal how the facilitators treat an analytic distinction between process and content to be a natural fact about communication. This factual presumption entails a nascent philosophy of practice--"process management"--that facilitators use to persuade clients, and practitioners, about the trustworthiness and credibility of their servicing. The ironic consequence of this philosophy is the denial of the very influence and expert judgment they exercise in their professional action. This is not only problematic for individual practitioners and consumers of facilitation services but for the development of facilitation practice itself. The implications of this analysis for facilitation practice and applied communication research are discussed in terms of a "design stance" toward communication expertise which is an alternative to the "technocratic stance" that currently frames practitioner, consumer, and research interests in GDSS facilitators.

Distributed certification application via a trusted dealer

Distributed certification via threshold cryptography is much more secure than other ways to protect certification authority (CA)'s private key, and can tolerate some intrusions. As the original system such as ITTC, etc., is unsafe, inefficient and impracitcal in actual network environment, this paper brings up a new distributed certification scheme, which although it generates key shares concentratively, it updates key shares distributedly, and so, avoids single-point failure like ITTC. It not only enhances robustness with Feldman verification and SSL protocol, but can also change the threshold (t, k) flexibly and robustly, and so, is much more practical. In this work, the authors implement the prototype system of the new scheme and test and analyze its performance.

Sedimentation of a single particle between two parallel walls

The sedimentation of a single circular particle between two parallel walls was studied by means of direct numerical simulation (DNS) and experiment. The improved implementation of distributed Lagrange multiplier/fictitious domain method used in our DNS is a promising new way for simulation of particulate flows. The settling behaviors of the particle are presented ranging in Reynolds number from 0 to about 700, which showed that our results for low Reynolds numbers agreed well with that reported before. Nevertheless, for higher Reynolds numbers our results were different from theirs. The long-term mean equilibrium positions in our results were all on the centerline, but not at off-center position as reported before. In order to validate our simulation, experiments were also conducted. The results showed that the sedimenting behavior simulated in this paper agreed well with our experiment result.
