Women, Equity and Participatory Water Management in Brazil

Public participation in resource management is regarded as a central pillar of sustain- able development. Water management is a foremost example, and women globally are prime users and protectors of water. Yet the effectiveness of participatory water man- agement practices is seldom examined from a feminist perspective. This article estab- lishes a methodological framework for such an inquiry, drawing on ecofeminist theory and the Brazilian concept of ‘feminist transformative leadership’ to consider gender, race and class aspects of participatory water management in Brazil.This research was supported by the Social Sciences and Humanities Research Council of Canad

Women and Deliberative Water Management in Brazil

In this paper we consider some gender aspects of the evolution of water management in Brazil. In our work on women and water, we have been inspired by ecofeminist philosophy and the concept of 'feministThis research was supported by the Social Sciences and Humanities Research Council of Canad

Geodesics around line defects in elastic solids

Topological defects in solids, usually described by complicated boundary conditions in elastic theory, may be described more simply as sources of a gravity- like deformation field in the geometric approach of Katanaev and Volovich. This way, the deformation field is described by non-Euclidean metric that incorporates the boundary imposed by the defects. A possible way of gaining some insight into the motion of particles in a medium with topological defects (e.g., electrons in a dislocated metal) is to look at the geodesics of the medium around the defect. In this work, we find the exact solution for the geodesic equation for elastic medium with a generic line defect, the dispiration, that can either be a screw dislocation or a wedge disclination for particular choices of its parameters.Comment: 10 pages, Latex, 4 figures, accepted for publication in Phys.

Configurational entropy in f(R,T)f(R,T) brane models

In this work we investigate generalized theories of gravity in the so-called configurational entropy (CE) context. We show, by means of this information-theoretical measure, that a stricter bound on the parameter of $f(R,T)$ brane models arises from the CE. We find that these bounds are characterized by a valley region in the CE profile, where the entropy is minimal. We argue that the CE measure can open a new role and an important additional approach to select parameters in modified theories of gravitation

Solid State Analog for He-McKellar-Wilkens Quantum Phase

In this letter we investigate the quantum dynamics of a quasiparticle in the presence of a charged screw dislocation submitted to a uniform magnetic field. Analysing the quantum scattering for this quasiparticle we observed the appearance of a topological quantum phase in the solution and demonstrate that this phenomenon is the solid state analog of the He-McKeller-Wilkens effect.Comment: 7 pages, epl styl
