Cinquant'anni dopo Bretton Woods: dollaro e sistema monetario internazionale tra storia e presente
No full textOn the occasion of the 50th anniversary of the suspension of the convertibility of dollars into gold by the U.S. government, which led to the demise of the Bretton Woods international monetary system (1944), this article offers a contribution to understanding the key features of Bretton Woods. It analyses the mid-term devel- opments that triggered its crisis in the early Seventies, and why nowadays the U.S. currency still serves as the pillar of world trade and payments, and is the most important reserve currency and means of payment. Today these questions are all the more worth addressing as the U.S. economy share in total world trade is on a downward trend and new currencies (Euro, Renminbi) are coming to centre stage in world economic affairs. The author traces the main features of the international monetary system born out of the end of 19th century Gold Standard, and laid out at Bretton Woods; the various reasons behind the origins of its collapse during the 1960s; a reflection on the central role of the U.S. dollar in world trade and payments throughout the last fifty years against the framework of the rampant ascendancy of new global financial players
Torres sobre la narrativa de la selva en América Latina
No full textBased on his fascination with literature, in his book Del infierno verde al paraíso perdido. La narrativa de la selva en América Latina [which could translate as rom Green Hell to Paradise Lost: The Narrative of the Jungle in Latin America], Vicente Francisco Torres proposes a journey into texts appreciative of the theme of Latin American jungles. This research into the jungles expressed in words recorded by Vicente Francisco Torres sees jungles as both idealized and threatening spaces that have eventually been turned through multiple ambitions into spaces that are close to deterioration, including the Lacandon and the Petén jungles. The author offers a passionately broad look at a theme, the narrative of the jungle, the analysis of which is inexhaustible.Con base en su fascinación por la literatura, Vicente Francisco Torres propone, en su libro Del infierno verde al paraíso perdido. La narrativa de la selva en América Latina, un recorrido por aquellos textos en los cuales puede darse una apreciación de la temática sobre la selva de América Latina. Espacio idealizado, amenazante, luego transformado, por múltiples ambiciones, en uno cercano al deterioro, la selva expresada en palabras, que consigna Vicente Francisco Torres, es una indagación que incluye la selva lacandona y la selva de El Petén. La aportación del autor está en haber ofrecido una apasionada amplia mirada sobre una temática, la narrativa de la selva, que lejos está de agotarse en el análisis de sus componentes
Systemic Vulnerability and Risk Assessment of Transportation Systems Under Natural Hazards Towards More Resilient and Robust Infrastructures
No full textAbstractTransportation infrastructures are complex systems of various connected components like bridges, roads, tunnels, embankments, retaining walls in case of a highway system or wharfs, cranes, buildings, utility systems in case of port facilities. Due to their spatial extent, they are exposed to variable natural hazards such as earthquakes, tsunami or landslides. Experience from past disastrous events shows that transportation infrastructures are quite vulnerable due to the lack of redundancy, the lengthy repair time, the rerouting difficulties or the cascading failures and interdependencies. Their damage could be greatly disruptive in terms of safety of life, business disruption, access to emergency services and key lifelines utilities, rescue operations and socio-economic impacts. Therefore, in terms of resilience it is important to recognize and quantify the risks and global losses associated to damages of transportation systems and to establish efficient risk mitigation strategies. These include, among others, enhancement of emergency preparedness, strengthening of existing structures and improvement of the recovery planning.Herein an integrated framework for the probabilistic systemic vulnerability and risk assessment of transportation and utility networks is presented, based on the achievements of the recently completed EC project SYNER-G (www.syner-g.eu) and the ongoing EC project STREST (www.strest-eu.org). The infrastructure is modeled according to a detailed taxonomy. The framework encompasses in an integrated fashion all aspects in the chain, from regional hazard to fragility assessment of components to the socio-economic impacts of a natural disaster, accounting for relevant uncertainties within an efficient quantitative simulation scheme, and modeling interactions between multiple component systems in the taxonomy. Selected Performance Indicators (PIs) are calculated for each network based on the estimated damages and functionality losses of the different components under the given hazards.The methodology and tools are demonstrated through case studies in the road network and the harbor of Thessaloniki city, Greece, under seismic hazard and associated geotechnical hazards (i.e. soil liquefaction). The applications include assessments of systems’ performance considering the spatial seismic hazard with correlation of ground motion intensities, the vulnerability of the network components, and the effect of interactions within the system, as well as, between components of different systems. In particular, road disruptions can be caused due to direct damage of road segments and bridges, as well as building and overpass collapses. Harbor operations can be disturbed due to failures of waterfront structures and cargo handling equipment, as well as disruptions to the electric power supply and building collapses. The systemic risk for the road network and harbor is calculated, specifically focusing on the short-term impact of seismic events (just after the earthquake) and the risk curves (i.e. mean annual rates of exceedance for loss in performance of the infrastructures) are provided. The significant elements for the functionality of each system are defined through correlation factors to the system PIs. Such results can contribute to the decision-making regarding the enhancement of existing and the robust development of new infrastructures in the frame of safety and resiliency

Blanche Selva: her pianistic legacy
No full textBlanche Selva (1884-1942) was an eminent French-Catalan pianist, pedagogue, author, editor and composer. She acquired a formidable technique that allowed her to give the first performance of important works such as Albéniz’s Iberia while being equally comfortable playing all of Bach’s keyboard music, 32 Beethoven Sonatas and copious amounts of new music. She held prominent positions as a teacher, first at the Schola Cantorum in Paris, then the conservatoires in Strasbourg, Prague and the École Normale in Paris. She wrote several books, including a treatise on piano technique and her catalogue as an editor comprises nearly 200 works. Selva also composed pieces for solo piano and organ as well as chamber music and choral works.
Despite such a versatile and successful career, Blanche Selva’s role in the development of twentieth-century pianism has been seriously overlooked. This thesis provides the first comprehensive, English-language account of her career, addressing her under-representation in modern scholarship of the period. Further, her unique trajectory and exceptional musical and technical insights offer viable solutions applicable to the modern pianist and piano teacher.
The thesis is based on extensive documentary evidence, most notably concert programmes, letters and her own recordings, as well as practice-based research. Her seven-volume treatise on teaching piano technique — L’Enseignement musical de la technique du piano (1916-1925) — has been examined at a practical level by applying its precepts to my own piano practice and in lessons with my students. I have also conducted interviews with pupils of former students of Selva to understand better what aspects, if any, of her method, have permeated later teaching practices.
Blanche Selva emerges from this research as a remarkable musician and personality whose study will better inform our views of early twentieth-century performance practice, where some women had a more influential role than they have been given credit for. Her technical proposals are unique in their scope and the amount of detail that she provides for their study is likewise remarkable. Her method is sound, and its study will help modern pianists and teachers alike. Likewise, a thorough examination of her recorded work provides a tangible testament to her technical and musical abilities as well as the modernity of her approach, opening avenues for pianists of the twenty-first century
