Employment Density in Ile-de-France: Evidence from Local Regressions

2009

In recent decades, cities have experienced a particularly intense phase of urban sprawl. Urban growth has been characterized by the spatial concentration of population in urban areas and the concomitant extension of those urban areas (Nechyba and Walsh 2004). Urban sprawl has also been accompanied by major reorganizations of urban areas with regard to the location choices of households and firms. More specifically, most cities in developed countries have experienced several waves of suburbanization of economic activities: “an economic definition of suburbanization is a reduction in the fraction of a metropolitan area’s population or employment that is located in the central city (correspond…

On Utilizing Stochastic Non-linear Fractional Bin Packing to Resolve Distributed Web Crawling

2014

This paper deals with the extremely pertinent problem of web crawling, which is far from trivial considering the magnitude and all-pervasive nature of the World-Wide Web. While numerous AI tools can be used to deal with this task, in this paper we map the problem onto the combinatorially-hard stochastic non-linear fractional knapsack problem, which, in turn, is then solved using Learning Automata (LA). Such LA-based solutions have been recently shown to outperform previous state-of-the-art approaches to resource allocation in Web monitoring. However, the ever growing deployment of distributed systems raises the need for solutions that cope with a distributed setting. In this paper, we prese…

Effect of fatigue on the intra-cycle acceleration in front crawl swimming: a time-frequency analysis.

2007

The present study analyzes the changes in acceleration produced by swimmers before and after fatiguing effort. The subjects (n=15) performed a 25-m crawl series at maximum speed without fatigue, and a second series with fatigue. The data were registered with a synchronized system that consisted of a position transducer (1 kHz) and a video photogrametry (50 Hz). The acceleration (m s−2) was obtained by the derivative analysis of the variation of the position with time. The amplitude in the time domain was calculated with the root mean square (RMS); while the peak power (PP), the peak power frequency (PPF) and the spectrum area (SA) were calculated in the frequency domain with Fourier analysi…

Clustering cities through urban metrics analysis

2017

[EN] This paper describes a process for measuring and characterizing urban morphological zones. These urban zones are delineated for the entire area of Spain, independently of administrative boundaries and excluding demographic data, using a high resolution land-use dataset. Given the rich information available on land cover and subsequently assigned population data, it is possible to calculate a set of urban spatial metrics to classify these urban zones into homogenous morphological groups. Four types of urban agglomerations are identified in Spain by working with these urban metrics and applying a final cluster analysis. Although these groups have a general complex monocentric typology, e…

Thought Experiments, Justice and Character

2012

A significant number of philosophers seem to assume that the study of thought experiments in light of a series of sketchy examples (and counterexamples) constitutes the best means to advance the philosophical debate. It is not my purpose to deny that thought experiments must play a role in philosophical reflection on moral issues, but to stress the need to complement this methodological resource with other means of understanding that may help us to discern the moral demands we may eventually confront. For, otherwise, one may unkowingly project onto the thought experiment itself a rather elementary comprehension of our moral practices, which may thereby seem confirmed.

Reconocimiento recíproco y autorrespeto en la teoría de la justicia de John Rawls

2015

Esta tesis tiene tres partes. En la primera analizo críticamente los artículos que Rawls publicó entre los años 1951 y 1968 con la intención de buscar en ellos las bases para la elaboración de su filosofía moral. Mi hipótesis de interpretación sostiene que el reconocimiento recíproco y el autorrespeto (self-respect) constituyen elementos centrales en la elaboración de la bases morales de la concepción rawlsiana de la justicia como equidad. La segunda parte de esta investigación está orientada al análisis y valoración del rol que juegan las nociones de reconocimiento recíproco y autorrespeto en la construcción madura del proyecto de la justicia como equidad que Rawls expone en A Theory of Ju…

Physical oceanography, sea-bed photographs and videos of benthos from the Weddell Sea taken with remote operated vehicle CHEROKEE during POLARSTERN c…

2010

The marine ecosystem on the eastern shelf of the Antarctic Peninsula was surveyed 5 and 12 years after the climate-induced collapse of the Larsen A and B ice shelves. An impoverished benthic fauna was discovered, that included deep-sea species presumed to be remnants from ice-covered conditions. The current structure of various ecosystem components appears to result from extremely different response rates to the change from an oligotrophic sub-ice-shelf ecosystem to a productive shelf ecosystem. Meiobenthic communities remained impoverished only inside the embayments. On local scales, macro- and mega-epibenthic diversity was generally low, with pioneer species and typical Antarctic megabent…

¿Metrópolis dispersas?

2010

La cuestión de la dispersión urbana constituye hoy un tema de investigación alrededor del cual se ha ido concentrando el interés disciplinar y político-institucional. Tal interés encuentra su respuesta en datos estadísticos (EEA, 2006) que confirman que: el 75% de la población europea vive en áreas urbanas; más de un cuarto del territorio europeo resulta urbanizado, y según las estimaciones en 2020 aproximadamente cerca del 80% de los europeos vivirá en áreas urbanas. Es un campo de la investigación todavía abierto y sobre el cual este trabajo de tesis ha querido reflexionar, siendo consciente que en urbanismo el conocimiento es una acción cognitiva y, al mismo tiempo, proyectual. Por lo ta…

The impractical supremacy of the local identity on the worthless soils of Mappano

2016

Introduction Soil is under pressure worldwide. In Italy, in the last two decades, land consumption has reached an average rate of 8 m2, demonstrating the failure of urban planning in controlling these phenomena. Despite the renewed recognition of the central role of soil resources, which has triggered numerous initiatives and actions, soil resources are still seen as a second-tier priority. No governance body exists to coordinate initiatives to ensure that soils are appropriately represented in decision-making processes. Global Soil Partnership draws our attention to the need for coordination to avoid fragmentation of efforts and wastage of resources. Both at a global and at a local level, …
