Sustainability of economic development and governance patterns in water management - an overview on the reorganisation of public utilities in Campania, Italy, under EU Framework Directive in the field of water policy (2000/60/CE)
No full textThe paper addresses the issue of sustainable development in water policy under the EU Framework Directive (2000/60/CE), and its implications on the governance of public utilities. Economic efficiency and environmental protection, far from being contradictory, are necessarily complementary in order to achieve the EU Water Framework Directive principles and objectives. Assuming public utilities as “environmental services”, the first part focuses on the theory of economic regulation for public utilities and innovative models of public/private governance for water management. In the second part, following the steps undertaken in Campania (since the first national reform in 1994), the paper tries to identify the main trends in water policies and management, resulting from the local governement efforts to comply with both environmental protection requirements under the EU Framework Directive and economic development programmes. The field of analysis is EU Structural Funds policy, as implemented by the Regional Operational Programme of Campania 2000-2006, which supports private and public investments in water infrastructures and management. According to the European regional policy, environmental protection requirements must be integrated into the definition and implementation of development programmes aimed at financing water infrastructures and innovative management of water services. The mid-term review on the performance of Structural Funds in Campania, shows that public/private partnership plays a crucial role in water policy, even for the integration of environmental concerns into the reorganisation of public utilities management.
The geometry of Newton's law and rigid systems
No full textsummary:We start by formulating geometrically the Newton’s law for a classical free particle in terms of Riemannian geometry, as pattern for subsequent developments. For constrained systems we have intrinsic and extrinsic viewpoints, with respect to the environmental space. Multi–particle systems are modelled on -th products of the pattern model. We apply the above scheme to discrete rigid systems. We study the splitting of the tangent and cotangent environmental space into the three components of center of mass, of relative velocities and of the orthogonal subspace. This splitting yields the classical components of linear and angular momentum (which here arise from a purely geometric construction) and, moreover, a third non standard component. The third projection yields a new explicit formula for the reaction force in the nodes of the rigid constraint
