Participatory process management

Although the process of public and stakeholder participation continues to be intensively investigated and discussed in academic circles, the implementation of participatory methods in practice remains problematic. This can be attributed to the lack of knowledge transfer on the one hand, and the general underestimation of participatory approaches in planning processes on the other.\ud A possible solution - participatory processmanagement - is introduced in this article. Participatory process management means that all participatory activities are embedded in the overall planning activities of a project. The most significant criteria for a participatory process are identified as ’objectives’, ’constraints’ and ’process’which together forma framework for combining generally applicablemethodswith local constraints and the objectives of a project. Themain elements of the participatory management framework introduced here are levels and classes of participation and a generic process scheme includingmonitoring and evaluation of participatory processes. This work is based upon long-term experiences of consultants and scientists. However, the insights from the InterReg project TRUST are particularly valuable and confirm the hypotheses that different water management projects are comparable in terms of their participatory process performance. The participatory management framework is a step forward in closing the gap between scientific knowledge about participatory methods and their applicability in practice

Classifying Cantor Sets by their Fractal Dimensions

In this article we study Cantor sets defined by monotone sequences, in the sense of Besicovitch and Taylor. We classify these Cantor sets in terms of their h-Hausdorff and h-Packing measures, for the family of dimension functions h, and characterize this classification in terms of the underlying sequences.Comment: 10 pages, revised version.

Cross-shelf and seasonal variation in larval fish assemblages on the southeast United States continental shelf off the coast of Georgia

Seasonal and cross-shelf patterns were investigated in larval fish assemblages on the continental shelf off the coast of Georgia. The influence of environmental factors on larval distributions also was examined, and larval transport processes on the shelf were considered. Ichthyoplankton and environmental data were collected approximately every other month from spring 2000 to winter 2002. Ten stations were repeatedly sampled along a 110-km cross-shelf transect, including four stations in the vicinity of Gray’s Reef National Marine Sanctuary. Correspondence analysis (CA) on untransformed community data identified two seasonal (warm weather [spring, summer, and fall] and winter) and three cross-shelf larval assemblages (inner-, mid-, and outer-shelf ). Five environmental factors (temperature, salinity, density, depth of the water column, and stratification) were related to larval cross-shelf distribution. Specifically, increased water column stratification was associated with the outer-shelf assemblage in spring, summer, and fall. The inner shelf assemblage was associated with generally lower temperatures and lower salinities in the spring and summer and higher salinities in the winter. The three cross-shelf regions indicated by the three assemblages coincided with the location of three primary water masses on the shelf. However, taxa occurring together within an assemblage were transported to different parts of the shelf; thus, transport across the continental shelf off the coast of Georgia cannot be explained solely by twodimensional physical factors

Homochirality in an early peptide world

A recently proposed model of non-autocatalytic reactions in dipeptide reactions leading to spontaneous symmetry breaking and homochirality is examined. The model is governed by activation, polymerization, epimerization and depolymerization of amino acids. Symmetry breaking is primarily a consequence of the fact that the rates of reactions involving homodimers and heterodimers are different, i.e., stereoselective, and on the fact that epimerization can only occur on the N-terminal residue and not on the Cterminal residue. This corresponds to an auto-inductive cyclic process that works only in one sense. It is argued that epimerization mimics both autocatalytic behavior as well as mutual antagonism - both of which were known to be crucial for producing full homochirality.Comment: 19 pages, 7 figures, 3 boxe
