Commentary: Actions to end violence against women : a multi-sector approach
Many forms of violence affect women and girls, such as physical and sexual abuse, trafficking, female genital mutilation, early and forced marriage, murders in the name of honour or dowry, and sexual harassment and abuse by authority figures. Prevention is imperative, and promising programmes exist that need to be tested and scaled up. The UNâs post-2015 global agenda, currently under discussion, must include a target to eliminate violence against women and girls, which supports the actions outlined in this article
Strategic equilibrium in economies with a continuum of agents
In this note, a pure exchange economy with a continuum of agents who behave strategically in endowments and preferences is considered. A notion of equilibrium, namely, strategic equilibrium is defined. It is shown that price-taking and strategic behavior leads to identical results
Linear exchange economies with a continuum of agents.
The purpose of this paper is to study how the equilibrium prices vary with respect to the initial endowments in a linear exchange economy with a continuum of agents. We first state the model and give conditions of an increasing strength for existence, uniqueness and continuity of equilibrium prices.Then, if we restrict ourselves to economies with essentially bounded initial endowments and if we assume that there is, from the point of view of preferences, only a finite number of types of agents, we show that, on an open dense subset of the space of initial endowments, the equilibrium price vector is an infinitely differentiable function of the initial endowments. The proof of this claim is based on an explicit formula allowing to compute the equilibrium price vector around a so-called "regular" endowment where it is known.Linear utilities; Indirect utility function; Walrasian equilibrium; Atomless measure space of agents; Open mapping theorem;
Modeling changes in the tidal propagation and its implication for vessel navigation in Guadalquivir estuary ( Spain)
The Port of Seville is an inland harbour located in the Guadalquivir Estuary some 80 km
from the river mouth and is the unique Spanish inland port. Vessel traffic in the estuary is
a relevant economic activity and a suitable trade-off between vessel draught and safety to
prevent ship aground is required and to optimize the port operability. The Guadalquivir is
a mesotidal estuary with tidal range of 2-3 m, an important fraction of the minimum depth
of the navigation waterway (presently 6.5m). Upstream navigation is favoured around
high water as the tide progresses at 12 knots, which is comparable to the vessel speed,
thus allowing greater vessel draughts. Oceanwards navigation of heavy vessels, on the
contrary, is hampered by the tide because a low water is unavoidably met when heading
downstream.
A 3D, high resolution hydrodynamic model has been implemented in the whole estuary to
study the tidal propagation. The model is forced by the oceanic tide at the mouth and
freshwater discharges controlled by an upstream dam at the head. It has been satisfactorily
validated and predicts tidal oscillations with high accuracy (less than 4 cm in amplitude
and 20 min in phase everywhere in the estuary). Based on the model outputs of tidal
heights and currents and using present-day estuary bathymetry, a MATLAB application
has been developed for shipping planning (Vessel Traffic Decision Support System,
VTDSS). The application allows the final users to test different traffic scheduling
scenarios in order to assess the effects on navigational patterns and explore possible
management and policy scenarios under sea level rise and changes in tidal propagation. A
description of the model and an overview of the VTDSS are presented here; the
effectiveness as a decision support tool is demonstrated via the simulated navigation time
of several vessels.Universidad de MĂĄlaga. Campus de Excelencia Internacional AndalucĂa Tech.

Strategic equilibrium in economies with a continuum of agents.
In this note, a pure exchange economy with a continuum of agents who behave strategically in endowments and preferences is considered. A notion of equilibrium, namely, strategic equilibrium is defined. It is shown that price-taking and strategic behavior leads to identical results.Strategic equilibrium; Pure exchange economy; Continuum economy;
