Informe final de la beca BE realizada en la California San Francisco

Investigación producida a partir de una estancia de dos meses en el laboratorio de la Dra. Donna M. Ferriero del departamento de neurología de la University of Californai San Francisco. A partir de un modelo de lesión cerebral isquemica en ratas postnatales, se han estudiado los efectos de la interacción con integrinas en el desarrollo de la lesión como estrategia terapéutica.

La Misión Indígena San Francisco Solano de Tacaaglé en las tierras fiscales de Formosa (1900-1950)

[spa]La Misión Indígena fue inaugurada en el año 1901, en la zona del río Pilcomayo del Territorio Nacional de Formosa, precisamente al costado de la concesión paraguaya otorgada a Elisa (Elizabeth Alicia) Lynch. Desde entonces, fue trasladada, primero a Tacaaglé en 1902, donde adquirió el nombre de Misión San Francisco Solano, y posteriormente, en 1915, al riacho El Porteño. Los misioneros franciscanos asumieron la tarea de formar a “colonos indígenas” tobas y pilagás para la producción de azúcar. Se analiza la evolución de la Misión franciscana y el impacto de la llegada del Ferrocarril de Formosa a Embarcación (F.C.F.E.). La documentación utilizada se encuentra en la Biblioteca y Archivo Históricos de la Provincia Franciscana de San Miguel, del Museo Conventual de San Carlos Borromeo ubicado en San Lorenzo, Provincia de Santa Fe

What do outside experts bring to a committee? Evidence from the Bank of England

We test whether outside experts have information not available to insiders by usingthe voting record of the Bank of England's Monetary Policy Committee. Memberswith more private information should vote more often against conventional wisdom,which we measure as the average belief of market economists about future interest rates. We find evidence that external members indeed have information notavailable to internals, but also use a quasi-natural experiment to show they mayexaggerate their expertise to obtain reappointment. This implies that an optimalcommittee, even outside monetary policy, should potentially include outsiders, butneeds to manage career concerns.

Monetary policy with signal extraction from the bond market

Monetary policy is conducted in an environment of uncertainty. This paper sets upa model where the central bank uses real-time data from the bond market togetherwith standard macroeconomic indicators to estimate the current state of theeconomy more efficiently, while taking into account that its own actions influencewhat it observes. The timeliness of bond market data allows for quicker responsesof monetary policy to disturbances compared to the case when the central bankhas to rely solely on collected aggregate data. The information content of theterm structure creates a link between the bond market and the macroeconomythat is novel to the literature. To quantify the importance of the bond market asa source of information, the model is estimated on data for the United Statesand Australia using Bayesian methods. The empirical exercise suggests that thereis some information in the US term structure that helps the Federal Reserve toidentify shocks to the economy on a timely basis. Australian bond prices seemto be less informative than their US counterparts, perhaps because Australia is arelatively small and open economy.

Physico-chemical analysis of Albian (Lower Cretaceous) amber from San Just (Spain): implications for palaeoenvironmental and palaeoecological studies.

Amber from a Lower Cretaceous outcrop at San Just, located in the Eastern Iberian Peninsula (Escucha Formation, Maestrat Basin), was investigated to evaluate its physico-chemical properties. Thermogravimetric (TG) and Differential Thermogravimetric (DTG) analyses, infra-red spectroscopy, elemental and C-isotope analyses were performed. Physico-chemical differences between the internal light nuclei and the peripheral darker portions of San Just amber can be attributed to processes of diagenetic alteration that preferentially took place in the external amber border colonized by microorganisms (fungi or bacteria) when the resin was still liquid or slightly polymerized. δ13Camber values of different pieces of the same sample, from the nucleus to the external part, are remarkably homogeneous, as are δ13Camber values of the darker peripheral portions and lighter inner parts of the same samples. Hence, neither invasive microorganisms, nor diagenetic alteration, changed the bulk isotopic composition of the amber. δ13C values of different amber samples range from -21.1 to -24 , as expected for C3 plant-derived material. C-isotope analysis, coupled to palaeobotanical, TG and DTG data and infra-red spectra, suggests that San Just amber was exuded by only one conifer species, belonging to either the Cheirolepidiaceae or Aracauriaceae, coniferous families probably living under stable palaeoenvironmental and palaeoecological conditions.
