Reliability Analysis of a Controlled Stage-Constructed and Reinforced Embankment on Soft Ground Using 2D and 3D Models
2020
Geosynthetic reinforcement has become a very practical technique to improve geotechnical structure safety. In spite of improved soil behavior, structures are affected by uncertainties related to soil and reinforcement material properties. This paper aims to present a reliability analysis in order to take statistical information (uncertainties) into account in a safety analysis of reinforced embankments. The analysis was used in a case study on a controlled stage-constructed embankment on soft ground in order to investigate its probabilistic stability. Modeling was performed by commercial geotechnical software usage (GeoStudio and RocScience packs, SIGMA/W+SLOPE/W and SLIDE³, respectively) a…
High rates of short-term dynamics of forest ecosystem services
2021
Currently, the main tools for assessing and managing ecosystem services at large scales are maps providing snapshots of their potential supply. However, many ecosystems change over short timescales; thus, such maps soon become inaccurate. Here we show high rates of short-term dynamics of three key forest ecosystem services: wood production, bilberry production and topsoil carbon storage. Almost 85% of the coldspots and 65% of the hotspots for these services had changed into a different state over a ten-year period. Wood production showed higher rates of short-term dynamics than bilberry production and carbon storage. The high rates of dynamics mean that static snapshot ecosystem service map…
Spatial econometrics and the hedonic pricing model: what about the temporal dimension
2014
Recent ready access to free software and toolbox applications is directly impacting spatial econometric modelling when working with geolocated data. Spatial econometric models are valuable tools for taking into account the possible latent structure of the price determination process and ensuring that the coefficients estimated are unbiased and efficient. However, mechanical applications can potentially bias estimated coefficients if spatial data is pooled over time because the applications consider the spatial dimension alone. Spatial models neglect the fact that data (e.g. real estate) may consist of a collection of spatial data pooled over time, and that time relations generate a unidirec…
Characteristics and definition and characterization of new Valencian urban areas
2014
La expansión urbanística, junto con la generalización de los procesos de descentralización residencial y económica, ha conducido a un nuevo modelo de ciudad dispersa caracterizado por la dificultad de establecer sus límites precisos. Utilizando un índice de densidad de ejes viarios procedente de una fuente comercial, y por tanto fácilmente actualizable, se ha delimitado el fenómeno urbano en la Comunidad Valenciana. Se discute la utilidad de la metodología y su capacidad para captar el hecho urbano a partir del contraste con la cartografía de usos del suelo de Corine. Urban expansion, along with the generalization of the processes of residential and economic decentralization has led to a ne…
Towards a sustainable and equitable blue economy
2019
The global rush to develop the ‘blue economy’ risks harming both the marine environment and human wellbeing. Bold policies and actions are urgently needed. We identify five priorities to chart a course towards an environmentally sustainable and socially equitable blue economy.
New Regionalism—Not Too Complex for the Media Watchdog
2014
As cities grow and expand, governance networks advocated by the “new regionalism” have become increasingly important for policy making in metropolitan areas. This article examines media reporting about governance networks and the effect this reporting has on democratic accountability and legitimacy. We use data from a standardized content analysis of newspaper coverage about metropolitan policy making in four European metropolitan areas (Zurich, Berlin, Paris, and London), as well as survey data on citizens’ attitudes. We find that the leading newspapers adequately cover governance processes and pay attention to both governmental and nongovernmental actors. Media content is correlated with…
Shear design of high strength concrete beams in MRFs
2019
This paper presents the criteria for the shear design of high strength concrete (HSC) beams in moment resisting frames (MRFs). The formulation of an analytical model is provided for the case of beams with longitudinal reinforcement in the presence of transverse stirrups. The model is of additive type, in the meaning that the shear resistance of the beam is evaluated as the sum of several contributions. In particular, the contribution of concrete, longitudinal rebars, and transversal reinforcement are taken into account. Furthermore, for assessing the concrete contribution, a classical approach is followed, according to which two effects arise in the shear mechanism: the arc and the beam eff…
Credit and financial markets in the Iberian Peninsula at the end of the Middle Ages. Historiographic production and recent developments
2021
El artículo examina la trayectoria de los estudios sobre el crédito y los mercados financieros en la Península Ibérica a finales de la Edad Media, desde los primeros trabajos sobre la usura y el préstamo a interés, fundamentalmente judío, en la primera mitad del siglo XX, hasta las líneas de investigación más recientes, que se ramifican en diversas direcciones, desde el marco teórico, doctrinal y legal del mercado del crédito y el estudio de los diferentes instrumentos financieros –préstamo a interés, crédito comercial y bancario, crédito a largo plazo en forma de censales y censos consignativos– a la deuda pública y el crédito privado, especialmente el crédito rural. Todos estos estudios m…
Dining out as a performative event
2020
Public events are scripted, staged and choreographed. Dining out is a perception-affect experience, but it is rare that the experience becomes a performative event in which guests are actors in the scene. The Madeleine’s Food Theatre in Copenhagen created a performative dining-out experience where guests did not have knowledge of the script, stage or choreography beforehand. When people became part of making a space into an event, they entered into unimaginable atmospheres and moods. The article explores the dining experience at Madeleine’s Food Theatre as a collage of body-mind impressions affected by different kinds of forces of presence. Paid open access
The great fire of medieval Valencia (1447)
2015
ABSTRACT:In March 1447, a great fire broke out in Valencia, caused by a former member of the municipal government. This fire destroyed many houses and craft workshops around the Market Square, the economic centre of the city. The municipal government had to compensate the citizens, who had lost everything, and restore everyday life in the area. A versatile Italian watchmaker living in Valencia was chosen to supervise the rehabilitation of the area. Under his direction, the debris was removed. Then after a conscious campaign of urban planning aimed at eliminating any traces of the old Islamic city, the streets were reconstructed according to the norms of the western city.
