Anisotropic dispersion, space competition, and the slowdown of the Neolithic transition

The front speed of the Neolithic (farmer) spread in Europe decreased as it reached Northern latitudes, where the Mesolithic (huntergatherer) population density was higher. Here, we describe a reaction diffusion model with (i) an anisotropic dispersion kernel depending on the Mesolithic population density gradient and (ii) a modified population growth equation. Both effects are related to the space available for the Neolithic population. The model is able to explain the slowdown of the Neolithic front as observed from archaeological data

Research based design: competition proposal for the Cyprus news agency

The paper attempts to explore the interrelation between a) the architects’ individualism and “pre-structures” b) research- based findings during the design process through experimentation and c)an integrated design approach, where morphology, construction and bioclimatic design are integrated from an early design stage. Through a thorough presentation and analysis of a competition proposal for the Cyprus News Agency, we discuss a number of important findings in relation to the present and possibly future form of the design studio. We suggest that the designer’s “prestructures” may not only be the basis for creative action, but also the basis for understanding and interpretation. Design informed and enriched at every stage by a research-based process, might well be the transmission and transformation of “prestructures”, a process of elaboration and discovery which facilitates and enhances design creativity and possibly allows for a multiplicity of approaches through a range of possibilities. Furthermore, an integrated approach from the early stages of the design process facilitates innovation in materials and systems.

República Bolivariana de Venezuela: la democracia como una idea-fuerza (Tema Central)

Tras años de democracia representativa, establecida bajo los parámetros de la democracia liberal, se inicia en 1998 en Venezuela un período de oportunidades políticas que da salida a los años de lucha y desencanto social producto de la deslegitimación del sistema político, a la vez que permite la resignificación de la democracia como una idea-fuerza, persiguiendo –a través de la superación de los límites formales– dar lugar a una concepción más exigente, que se origine y se nutra de las realidades organizativas y de lucha del pueblo venezolano. Sin embargo, la resignificación de la democracia venezolana es atravesada por la idea del socialismo del siglo XXI, apuntando hacia la construcción de un camino compartido, donde las tensiones entre diversos sectores de la población, entre ésta y el gobierno, y al interior del movimiento bolivariano implican mayores retos para la consolidación de esta idea. La democracia en Venezuela supera los límites teóricos entendiendo que ésta se construye y reconstruye en lo cotidiano, y solo así podrá conformarse como un proyecto histórico de transformación social.

Unleashing Competition in EU Business Services. CEPS Policy Brief No. 284, 24 September 2012

In most EU member states, the business services industry has booked no productivity growth during the last two decades. The industry’s performance in the other member states was weaker than that of its US counterparts. Exploring what may be causing this productivity stagnation, this policy brief reports that weak competition has contributed to the continuing malaise in European business services. The study analyzed the persistence (over time) of firm-level inefficiencies. The evidence further suggests that competition between small firms and large firms in business services is weak. Markets for business services work best in countries with flexible regulation on employment change and with low regulatory costs for firms that start up or close down a business. Countries that are more open to foreign competition perform better in terms of competitive selection and productivity. The policy simulations in this paper show that greater import openness strengthens competition in business services markets. The largest positive impact comes from lower regulatory barriers for growing and shrinking firms. More particularly, competitive selection would be fostered by a reduction of administrative and regulatory costs related to labour contracts, bankruptcy and start-up requirements. A key element of the European Commission’s Europe-2020 strategy is the Single European Market for Services. Business services form one of the largest industries in Europe – and given its productivity stagnation, it deserves to be a priority target of the Europe-2020 strategy. Improving the way the business services market functions may have large positive knock-on effects for the EU economy.
