A propósito de Arte prerrománico hispano de I.G. Bango Torviso

En vez de un monumento o una teoría científica se eleva aquí un libro al protagonismo de todo un artículo extenso: la gran monografía nueva de Bango sobre obras arquitectónicas y artísticas de la Hispania cristiana desde las postrimerías de la Tardoantigüedad hasta el fin del Altomedioevo. Así, más allá de la simple crítica, se pretende reflexionar y hacer reflexionar, a propósito de ese libro muy idóneo para ello, sobre nuestra responsabilidad de hacer justicia al legado monumental y nuestra obligación de informar bien al gran público.Instead of a monument or a scholarly theory, one single book is allowed here to be the subject of a detailed article: the new weighty publication of Bango's about Hispanic Christian architecture and art from the advanced period of Late Antiquity to the end of the Early Middle Ages. Thus, beyond the level of current criticism, there is an intention -using this case of a book which claims such an effort- to reflect and to caH for reflection on both our responsibility to appreciate the monumental heritage properly and our duty to provide the public with adequate information

The Impact of Logistics Performance on the Success of Trade Agreements

The purpose of this capstone project is to determine whether or not it is possible to predict the success and effectiveness of new trade agreements by looking at fundamental factors associated with efficient supply chain management. Typically, free trade agreements are analyzed using economic factors such as Gross Domestic Product or labor gains and losses. When this is done to determine whether or not a trade agreement is successful, it is usually backwards looking and too late for a country to opt out without economic repercussions. The aim of this study is to determine whether it is possible to predict the potential success of a free trade agreement. Furthermore, rather than using economic indicators to make predictions, I have decided to use supply chain, specifically logistics, metrics to conduct this study. Using logistics metrics is a better representation than economics, not only because the economics metrics mentioned are lagging indicators, but also because without sound logistics and the capability to move goods from point A to B, a trade agreement would fail. This study is comprised of two different quantitative analyses. First, I look at the Logistics Performance Index (LPI) compared to Net Trade to see if a relationship existed. The next step was to determine what factors drive LPI growth and should be a country’s focus for improving. The trade agreement focused on in this study was the Tripartite Free Trade Agreement encompassing 27 countries in Africa

Ionization heating in rare-gas clusters under intense XUV laser pulses

The interaction of intense extreme ultraviolet (XUV) laser pulses ($\lambda=32\rm\,nm$, $I=10^{11-14}$\,W/cm$^2$) with small rare-gas clusters (Ar$_{147}$) is studied by quasi-classical molecular dynamics simulations. Our analysis supports a very general picture of the charging and heating dynamics in finite samples under short-wavelength radiation that is of relevance for several applications of free-electron lasers. First, up to a certain photon flux, ionization proceeds as a series of direct photoemission events producing a jellium-like cluster potential and a characteristic plateau in the photoelectron spectrum as observed in [Bostedt {\it et al.}, Phys. Rev. Lett. {\bf 100}, 013401 (2008)]. Second, beyond the onset of photoelectron trapping, nanoplasma formation leads to evaporative electron emission with a characteristic thermal tail in the electron spectrum. A detailed analysis of this transition is presented. Third, in contrast to the behavior in the infrared or low vacuum ultraviolet range, the nanoplasma energy capture proceeds via {\it ionization heating}, i.e., inner photoionization of localized electrons, whereas collisional heating of conduction electrons is negligible up to high laser intensities. A direct consequence of the latter is a surprising evolution of the mean energy of emitted electrons as function of laser intensity.Comment: figure problems resolve
