Filosofías del don: Usos y abusos de la donación en la ética contemporánea

2013

El objetivo de este artículo es analizar el concepto de donación en la ética contemporánea. Este análisis se realiza en tres momentos: el primero se sitúa en la introducción y muestra que es un concepto importante en el que convergen la fenomenología, el personalismo y la hermenéutica. Esta convergencia no solo supone un uso frecuente del concepto sino un abuso del mismo cuando se construye de espalda a las mediaciones objetivas o institucionales que lo condicionan. El segundo presenta una antropología del don y muestra su relación con los objetos, la reciprocidad, la deuda y la libertad. En el tercer momento se describe la filosofía de la donación de Paul Ricoeur, donde se comprueba un uso…

Resilience and Convergence: Short vs.Long-Run Regional Effects of Economic Crises and Macroeconomic Policies

2020

Before the outbreak of the Great Recession, considerable attention was devoted to what makes a region successful, and why some regions grow faster than others, but researchers often overlooked how regions react to shocks and why this happens in a heterogeneous way. Furthermore, the classic literature on regional inequalities has mainly focused on the longterm relationship between economic growth and regional disparities and on the role of labor mobility, sometimes also as a mechanism of adjustment to labor demand idiosyncratic shocks. This literature trend has reversed since 2008, when investigation of the heterogeneous impact of shocks across areas became prominent in regional studies beca…

Numerical modeling of eastern Tibetan-type margin: Influences of surface processes, lithospheric structure and crustal rheology

2013

The eastern Tibetan margin is characterized by a steep topographic gradient and remarkably lateral variations in crustal/lithospheric structure and thermal state. GPS measurements show that the surface convergence rate in this area is strikingly low. How can such a mountain range grow without significant upper crustal shortening? In order to investigate the formation mechanism of the eastern Tibetan-type margins, we conducted 2D numerical simulations based on finite difference and marker-in-cell techniques. The numerical models were constrained with geological and geophysical observations in the eastern Tibetan margin. Several major parameters responsible for topography building, such as th…

Dynamics of the Comparative Advantages in Romanian Exports Compared to the European Union

2013

Abstract The main objective of this paper is to prove if the dynamics of the comparative advantages in Romania in the period of time 2000- 2011 has any convergence potential and if the specialization of production capacities has suffered modifications. For the study of the comparative advantage dynamics in Romanian exports compared to the European Union in the period of time 2000-2011, we analysed the modifications in the structure of the sections included in the Combined Nomenclature for national exports and we calculeted the Balassa and the Dalum indexes. In order to emphasize the convergence and the stability in time of the export structure we used the econometric tools specific to the r…

Neoclassical Convergence Versus Technological Catch-Up : A Contribution for Reaching a Consensus.

2004

http://www.businessperspectives.org/files/ppm/PPM_EN_2004_03pp15_42.pdf; International audience; New macro empirical evidence is provided to assess the relative importance of object andidea gaps in explaining the world income distribution dynamics over a benchmark period of 1960-1985. Results are then extended through 1995. Formal statistical hypothesis tests allow us to discriminatebetween two competing growth models: (i) the standard neoclassical growth model similarto that employed by Mankiw, Romer, and Weil (1992), and (ii) an endogenous growth modelclosely related to the Nelson and Phelps' approach (1966) that emphasizes the importance of technologytransfer in addition to factor accumu…

Threshold Neutral Pion Photoproduction on the Proton

2015

The neutral pion photoproduction on the proton near threshold has a very small scattering cross section when compared to the charged channels, which in ChPT is explained by strong cancellations between the lowest order pieces. Therefore it is very sensitive to higher-order corrections of chiral perturbation theory. We perform a fully covariant calculation up to chiral order p^3 and we investigate the effect of the inclusion of the Delta(1232) resonance as an explicit degree of freedom. We show that the convergence improves, leading to a much better agreement with data at a wide range of energies.

An adaptive multimeme algorithm for designing HIV multidrug therapies.

2007

This paper proposes a period representation for modeling the multidrug HIV therapies and an Adaptive Multimeme Algorithm (AMmA) for designing the optimal therapy. The period representation offers benefits in terms of flexibility and reduction in dimensionality compared to the binary representation. The AMmA is a memetic algorithm which employs a list of three local searchers adaptively activated by an evolutionary framework. These local searchers, having different features according to the exploration logic and the pivot rule, have the role of exploring the decision space from different and complementary perspectives and, thus, assisting the standard evolutionary operators in the optimizati…

Reaction-diffusion on dynamic inhibition areas: A bio-inspired link scheduling algorithm

2014

We present the Dynamic Inhibition Areas Reaction-Diffusion (DIA-RD) algorithm, a distributed medium access control protocol that globally maximizes the spatial reusability (number of simultaneous transmissions per unit area) of wireless sensor networks. This algorithm is able, in consequence, to minimize the number of time slots needed to schedule the set of demanded links, making it very efficient to solve the Shortest Link Schedule problem. DIA-RD combines accurate interference management, provided by the use of dynamic inhibition areas based on the physical interference model; and global intelligent behavior, provided by the bio-inspired technique known as Reaction-Diffusion. This techni…

Postprocessing of a Finite Element Scheme with Linear Elements

1987

In this contribution we first give a brief survey of postprocessing techniques for accelerating the convergence of finite element schemes for elliptic problems. We also generalize a local superconvergence technique recently analyzed by Křižek and Neittaanmaki ([20]) to a global technique. Finally, we show that it is possible to obtain O(h4) accuracy for the gradient in some cases when only linear elements are used. Numerical tests are presented.
