Bericht über die Forschungsreise No. 103, FS "Poseidon" [POS103], der Abteilung Meereschemie vom 16. bis 28.8.1983

Die Reise war mit dem Ziel unternommen worden, verschiedene Aspekte der Bildung und Diagenese organischer Substanzen im Oberflächenwasser und im anoxischen Tiefenwasser der Ostsee zu untersuchen. Da an diesen Vorgängen Mikroorganismen und Plankter beteiligt sind, wurden Wissenschaftler der Abteilungen Mikrobiologie und Benthosökologie eingeladen, an der Fahrt teilzunehmen

Pursuing Energy-Efficient Behavior in a Regulatory Environment: Motivating Policymakers, Program Administrators, and Program Implementers

This white paper examines how policymakers, program administrators, and program implementers can be motivated to pursue behavioral change in a regulatory environment. For the purposes of this report, behavior change is defined rather broadly, encompassing both behaviors associated with the purchase and installation of energy efficiency technologies as well as behaviors, decisions, and actions that might be thought of as more independent of technology. These include energy use habits, lifestyle choices, and consumption patterns. The insights and lessons discussed in this paper are drawn from a wide variety of sources including interviews with representatives from the energy and utility communities, and program documentation for energy-related programs and projects

On the rise and fall of networked societies

We review recent results on the dynamics of social networks which suggest that the interplay between the network formation process and volatility may lead to the occurrence of discontinuous phase transitions and phase coexistence in a large class of models. We then investigate the effects of negative links -- links inhibiting local growth of the network -- and of a geographical distribution of the agents in such models. We show, by extensive numerical simulations, that both effects enhance this phenomenology, i.e. it increases the size of the coexistence region.Comment: 6 pages, 4 figures, Proceedings of Granada Workshop 200
