- Is democracy favorable or adverse for the management of marine resources? While some studies find democracy to increase the likelihood of achieving sustainable development, others propose that democracy rather has negative effects on the environment. This paper contributes explicitly to this debate, but also adds insights from research arguing that the effects of democracy are conditioned by surrounding institutions. Building on this literature, we argue that the way democracy works - whether it is an instrument for collective action beneficial to the environment or an instrument for patronage and clientelism - depends on levels of economic development. The overall objective of the article is to test this proposition empirically. Employing time-series cross-section analysis and using Marine Trophic Index as a proxy for the health of marine ecosystems, we investigate the impact of democracy on the marine environment in a global sample from 1972 to 2006. The analysis provides interesting insights regarding the conditional role of economic development. We report negative effects of democracy in low income settings, but find that this pattern is reversed when economic development has reached a certain threshold. Finally, we discuss how democracy affects the prospects for sustainable development and based on our conclusions offer suggestions for future research. (C) 2014 Elsevier Ltd. All rights reserved.

Micellization of Water-Soluble Complex Salts of an Ionic Surfactant with Hairy Polymeric Counterions
- 2013

Journal article (peer-reviewed)abstract
- For ionic surfactants in general, a change from simple to polymeric counterions leads to increasing attraction between micelles, condensing them in a concentrated phase. In the present study, two novel “complex salts” were prepared in which the cationic surfactant hexadecyltrimethylammonium was neutralized by two different copolyions, both having poly(methacrylate) main chains randomly decorated with oligo(ethylene oxide) side chains. The presence of hydrophilic side chains in the polyion backbone is proposed as a strategy to stabilize the complex salt aggregates in aqueous solutions and prevent them from separating out in a concentrated phase. Surface tension experiments reveal that the complex salts form soluble nano-aggregates by surfactant ion self-assembly at a distinct critical micellization concentration (cmc), similar to the micellization of a conventional ionic surfactant. This is the first time that cmc values have been determined for complex salts in the absence of all other ions. The physicochemical nature of the aggregates formed was investigated by dynamic light scattering, nuclear magnetic resonance self-diffusion measurements and steady-state fluorescence spectroscopy. Much larger aggregates are formed when the temperature is increased, but the small aggregates reform at room temperature, suggesting that the soluble aggregates are equilibrium structures, much like the micelles of conventional surfactants.

Category O for Takiff sl(2)
- 2019
-
In: Journal of Mathematical Physics. - : AMER INST PHYSICS. - 0022-2488 .- 1089-7658. ; 60:11
-
Journal article (peer-reviewed)abstract
- investigate various ways to define an analog of Bernstein-Gelfand-Gelfand category O for the nonsemisimple Takiff extension of the Lie algebra sl(2). We describe Gabriel quivers for blocks of these analogs of category O and prove the extension fullness of one of them in the category of all modules.
