Adaptive comanagement in the Venice lagoon? An analysis of current water and environmental management practices and prospects for change
Adaptive comanagement (ACM) is often suggested as a way of handling the modern challenges of environmental governance, which include uncertainty and complexity. ACM is a novel combination of the learning dimension of adaptive management and the linkage dimension of comanagement. As has been suggested, there is a need for more insight on enabling policy environments for ACM success and failure. Picking up on this agenda we provide a case study of the world famous Venice lagoon in Italy. We address the following questions: first, to what extent are four institutional prescriptions typically associated with ACM currently practiced in the Venice system? Second, to what extent is learning taking place in the Venice system? Third, how is learning related to the implementation or nonimplementation of the prescriptions of ACM in the Venice system? Our analysis is based on interviews with stakeholders, participatory observation, and archive data. This paper demonstrates that the prescriptions of ACM are hardly followed in the Venice lagoon, but some levels of cognitive learning do take place, albeit very much within established management paradigms. Normative and relational learning are much rarer and when they do occur, they seem to have a relatively opportunistic reason. We propose that in particular the low levels of collaboration, because the governance system was deliberately set up in a hierarchical and mono-centric way, and the limited possibilities for stakeholder participation are implicated in this finding because they cause low levels of social capital and an incapacity to handle disagreements and uncertainty very well. © 2012 by the author(s)

Scaling mechanisms of energy communities:A comparison of 28 initiatives
Energy communities have mushroomed over the past decades. These initiatives have scaled, that is replicated their experiences, expanded membership, and diversified involved actors and technologies. The picture existing literature paints is hopeful that the scaling of local-scale action may translate into global-scale impact and thus effectively contribute to combating climate change. However, important gaps remain in understanding the (combinations of) conditions which are necessary for scaling with this goal in mind. This article pushes the boundaries of knowledge further by examining and comparing 28 energy communities through a fuzzy set Qualitative Comparative Analysis (QCA) and by identifying the necessary conditions of actionable scaling mechanisms. Our analysis identifies a high number (8) of necessary (combinations of) conditions for scaling. Addressing a strong need amongst policy makers to facilitate broader scaling of community initiatives, this article offers concrete insights on mechanisms that need to be in place to scale energy communities. Insights are developed on – for example – the type of capacity support needed, support structures and the tools needed for connecting communities with each other. These insights help corroborate empirically, for the first time the crucial leverage points that will support strategies for upscaling the impact of energy communities, and will enable them to flourish as an essential element of the global climate governance system.</p

The Roles of Experts and Expert-Based Information in the Advocacy Coalition Framework: Conceptual and Empirical Considerations Based on the Acid Mine Drainage Case Study in Gauteng, South Africa
The Advocacy Coalition Framework (ACF) remains one of the leading conceptual models in the policy sciences because it continues to be revised and updated as required. A focus area of the ACF that requires further theorization is the roles of experts and expert-based information in influencing policy problem contexts. Our article takes a necessary step in this direction by (1) evaluating the usefulness of Weible’s expectations regarding the uses of expert-based information in different types of policy subsystems and factors that contribute to shifts from one subsystem to another; and (2) making critical observations that result from this evaluation in the context of the controversial acid mine drainage policy case study in South Africa. The findings of our case study analysis indicate that Weible’s framework performed reasonably well but also revealed opportunities for further improvement. We therefore suggest adding awareness raising as a use of expert-based information, developing a typology of different types of experts who participate in policy subsystems, and including a focus on the use of expert-based information in policy subsystem shifts. We also reflect upon the relevance and importance of continuing to expand ACF applications to countries outside of North America and Western Europe
Nucleation and crystallization process of silicon using Stillinger-Weber potential
We study the homogeneous nucleation process in Stillinger-Weber silicon in
the NVT ensemble. A clear first-order transition from the liquid to crystal
phase is observed thermodynamically with kinetic and structural evidence of the
transformation. At 0.75 T_m, the critical cluster size is about 175 atoms. The
lifetime distribution of clusters as a function of the maximum size their reach
follows an inverse gaussian distribution as was predicted recently from the
classical theory of nucleation (CNT). However, while there is a qualitative
agreement with the CNT, the free energy curve obtained from the simulations
differs significantly from the theoretical predictions, suggesting that the
low-density liquid phase found recently could play a role in the nucleation
process.Comment: 21 page
