Bayesian dynamic modeling of time series of dengue disease case counts
2017
The aim of this study is to model the association between weekly time series of dengue case counts and meteorological variables, in a high-incidence city of Colombia, applying Bayesian hierarchical dynamic generalized linear models over the period January 2008 to August 2015. Additionally, we evaluate the model’s short-term performance for predicting dengue cases. The methodology shows dynamic Poisson log link models including constant or time-varying coefficients for the meteorological variables. Calendar effects were modeled using constant or first- or second-order random walk time-varying coefficients. The meteorological variables were modeled using constant coefficients and first-order …
Predicting dengue fever outbreaks in French Guiana using climate indicators
2016
Background Dengue fever epidemic dynamics are driven by complex interactions between hosts, vectors and viruses. Associations between climate and dengue have been studied around the world, but the results have shown that the impact of the climate can vary widely from one study site to another. In French Guiana, climate-based models are not available to assist in developing an early warning system. This study aims to evaluate the potential of using oceanic and atmospheric conditions to help predict dengue fever outbreaks in French Guiana. Methodology/Principal Findings Lagged correlations and composite analyses were performed to identify the climatic conditions that characterized a typical e…
A new system for animal products traceability and authentication: Use of DNA analysis of natural tracers and example of application to dry cured hams
2010
A few DNA based approaches have been developed to trace animal products from the farm to the consumer “fork”. These approaches make use of the animal DNA that can be recovered during all steps of t...
Assessing, measuring and modelling erosion in calanchi areas: A review
2016
Calanchi are erosion landforms characterised by a heavily dissected terrain with steep, unvegetated slopes and channels with a dendritic pattern, which rapidly incise and extend headwards. Recent literature focusing on badland systems highlights their similarity with other larger fluvial landforms, stating that these behave as a full size laboratory, due to their rapid development in space and time and to the diversity of geomorphic processes involved. In this paper, a brief review of the most important results on badland research is firstly presented. Then, the morphometric similarity between calanchi and other erosion landforms is discussed. Finally, models quantitatively relating the vol…
Spanish banking system restructuring after the crisis and the solvency in financial institutions. Consequences for savings banks
2013
La crisis financiera que ha afectado a todo el mundo ha tenido una incidencia especial en España. Las cajas de ahorros, que llevan más de 100 años desarrollando su gestión financiera, han desaparecido, por lo menos tal como venían desarrollando su actividad. Esta caída ha sido motivada por las políticas marcadas por el Banco de España, el Ministerio de Economía y el Fondo de Reestructuración Ordenada Bancaria (FROB) para salvar el sistema financiero español. El objetivo de estos organismos, según sus recomendaciones y la normativa emitida, era un proceso de bancarización de las cajas de ahorros y que todas las entidades financieras ganaran en tamaño, y de esta forma se deberían poner las ba…
De cortesanos y burgueses. Los nacionalismos como motor de la conservación y restauración
2011
[ES] Este artículo analiza el origen y desarrollo de los restauradores decimonónicos en el ámbito institucional español, a partir del estudio de caso de las ciudades de Madrid y Barcelona, como principales exponentes del desarrollo de la restauración española. Por un lado, la constitución de Madrid como capital política condicionó su mayor relevancia cultural, siendo pionera en la configuración del perfil profesional. Además, el centralismo madrileño justificó el protagonismo de la Rea l Academia de San Fernando como principal órgano de control de las restauraciones y del patrimonio. Por otro lado, Barcelona se erigió en el epicentro de la primera Revolución Industrial en España, hecho que …
Raw material variability as archaeological tools: Preliminary results from a geochemical study of the basalt vessel workshop at Iron Age Tel Hazor, I…
2016
The discovery of a basalt vessel workshop at Tel Hazor, one of the most important Iron Age sites in the Near East, marks a turning point in our understanding of stone artifact production and distribution during the1st millennium BCE. It offers a rare opportunity to characterize ancient raw material sources, production sites, and study production, trade and distribution systems. The basalt vessel workshop, the only one of its kind in the Levant, produced large quantities of bowl preforms and production waste. To better understand the production and distribution systems behind this specialized production center, in 2011 we initiated a focused geochemical project that concentrated on the produ…
Robots, labor markets, and universal basic income
2020
Automation is a big concern in modern societies in view of its widespread impact on many socioeconomic issues including income, jobs, and productivity. While previous studies have concentrated on determining the effects on jobs and salaries, our aim is to understand how automation affects productivity, and how some policies, such as taxes on robots or universal basic income, moderate or aggravate those effects. To this end, we have designed an experiment where workers make productive effort decisions, and managers can choose between workers and robots to do these tasks. In our baseline treatment, we measure the effort made by workers who may be replaced by robots, and also elicit firm repla…
Análisis funcional y urbanístico de la casa 11 de la Bastida de les Alcusses (Moixent, Valéncia)
2006
En el presente trabajo se muestran y analizan los resultados de las campañas de excavación en 1997 y 1998 en la Casa 11 de la Bastilla de les Alcusses (Moixent), situada en el sector este del poblado. Al hecho de poder estudiar la casa por primera vez en su conjunto, incluvendo el patio abierto entre la casa y el camino de ronda, se añade el análisis de las muestras carpológicas y de fauna que se recogieron del vertedero hallado en este patio. Estos datos obtenidos muestran por primera vez información proveniente del uso doméstico de una vivienda de la Bastida, algo que Eire imposible en los departamentos excavados entre 1928 y 1931.
La Torre Portal y el Portal Torreado en las fortificaciones ibéricas. Estudio de las entradas Norte y Oeste de la Bastida de les Alcusses (Moixent, V…
2005
En este trabajo presentamos dos estructuras halladas en el poblado ibérico de La Bastida de les Alcusses durante la campaña de excavación de 1998. Se trata de dos entradas (la Oeste y la Norte) que presentan la particularidad de ser edificios en sí mismos, si bien de factura diversa. Estos edificios se describen y se estudian constructivamente, analizando la posibilidad de que se trate de dos Portales, uno de ellos una Torre Portal y el otro un Portal Torreado, de larga tradición en la arquitectura oriental y, creemos, con paralelos en la arquitectura ibérica.
