Algorithms for Del Pezzo Surfaces of Degree 5 (Construction, Parametrization)
It is well known that every Del Pezzo surface of degree 5 defined over k is
parametrizable over k. In this paper we give an efficient construction for
parametrizing, as well as algorithms for constructing examples in every
isomorphism class and for deciding equivalence.Comment: 15 page
De los technopaegnia carolingios a la clerecĂa rabĂnica medieval. Nuevos horizontes en la literatura medieval a la luz de la poesĂa comparada
The concept of «mester de clerecĂa» is exposed here as a broad phenomenon whose origins are in Medieval non-quantitative latin poetry, in which, after the lost of the vowels quantity, the number of syllables is determining. This work will analyze two texts from a comparative point of view: a latin poem composed in tetrastichs of pentadecasyllables during the carolingian period, attributed to Paulin of aquilea, which reflects the initial status of medieval narrative poetry «a sĂlabas contadas»; and a castilian poem composed in the 13th century in «cuaderna vĂa» written by a Jewish author: the Coplas de Yosef. Both have a common source: the story of Joseph narrated in the book of Genesis. However, the literary procedures used by both authors, as well as the final results are very different. The contrastive analysis of the two texts make us determine the ideology present in each of them and also make us pose key questions related to the concept of «mester de clerecĂa», its definition, limits and evolution.El concepto de «mester de clerecĂa» se plantea aquĂ como un fenĂłmeno amplio que se inicia en la poesĂa mediolatina no cuantitativa, en la que el cĂłmputo silĂĄbico se convierte en un factor determinante tras la pĂ©rdida de la cantidad de las sĂlabas. En este trabajo analizaremos dos textos de forma comparativa: un poema latino compuesto en el perĂodo carolingio en cuartetas pentadecasilĂĄbicas y atribuido a Paulino de aquilea, que refleja ese estadio inicial de la poesĂa narrativa medieval «a sĂlabas contadas», y un poema castellano del siglo XIII en cuaderna vĂa escrito por un autor judĂo: las Coplas de Yosef. ambos textos tienen como base el mismo tema: el relato de JosĂ© narrado en el GĂ©nesis, sin embargo, la formulaciĂłn del mismo, asĂ como el resultado final son muy diferentes. El anĂĄlisis contrastivo de estos poemas nos lleva a determinar la ideologĂa que subyace a cada uno de ellos, asĂ como a plantear cuestiones claves en relaciĂłn al concepto de mester de clerecĂa, su definiciĂłn, lĂmites y evoluciĂłn
Econometric Evidence Regarding Education and Border Income Performance
This study examines the relationship between education and income in Texas counties that are located along the border with Mexico. Estimation results confirm ealrier research results for this region. Parameter heterogeneity underscores the increased importance of education in the service-oriented labor market that has emerged in recent years in the United States. Simulation results quantify the income gains that could potentially be realized if drop out rates were lowered in the border counties included in the sample.Education; Texas border incomes; applied econometrics
POSTDATA â Towards publishing European poetry as linked open data
POSTDATA is a 5 year's European Research Council (ERC) Starting Grant Project that started in May 2016 and is hosted by the Universidad Nacional de EducaciĂłn a Distancia (UNED), Madrid, Spain. The context of the project is the corpora of European Poetry (EP), with a special focus on poetic materials from different languages and literary traditions. POSTDATA aims to offer a standardized model in the philological field and a metadata application profile (MAP) for EP in order to build a common classification of all these poetic materials. The information of Spanish, Italian and French repertoires will be published in the Linked Open Data (LOD) ecosystem. Later we expect to extend the model to include additional corpora.
There are a number of Web Based Information Systems in Europe with repertoires of poems available to human consumption but not in an appropriate condition to be accessible and reusable by the Semantic Web. These systems are not interoperable; they are in fact locked in their databases and proprietary software, not suitable to be linked in the Semantic Web.
A way to make this data interoperable is to develop a MAP in order to be able to publish this data available in the LOD ecosystem, and also to publish new data that will be created and modeled based on this MAP. To create a common data model for EP is not simple since the existent data models are based on conceptualizations and terminology belonging to their own poetical traditions and each tradition has developed an idiosyncratic analytical terminology in a different and independent way for years. The result of this uncoordinated evolution is a set of varied terminologies to explain analogous metrical phenomena through the different poetic systems whose correspondences have been hardly studied â see examples in GonzĂĄlez-Blanco & RodrĂguez (2014a and b). This work has to be done by domain experts before the modeling actually starts. On the other hand, the development of a MAP is a complex task though it is imperative to follow a method for this development. The last years Curado Malta & Baptista (2012, 2013a, 2013b) have been studying the development of MAP's in a Design Science Research (DSR) methodological process in order to define a method for the development of MAPs (see Curado Malta (2014)). The output of this DSR process was a first version of a method for the development of Metadata Application Profiles (Me4MAP) (paper to be published). The DSR process is now in the validation phase of the Relevance Cycle to validate Me4MAP. The development of this MAP for poetry will follow the guidelines of Me4MAP and this development will be used to do the validation of Me4MAP.
The final goal of the POSTDATA project is: i) to be able to publish all the data locked in the WIS, in LOD, where any agent interested will be able to build applications over the data in order to serve final users; ii) to build a Web platform where: a) researchers, students and other final users interested in EP will be able to access poems (and their analyses) of all databases; b) researchers, students and other final users will be able to upload poems, the digitalized images of manuscripts, and fill in the information concerning the analysis of the poem, collaboratively contributing to a LOD dataset of poetry.Starting Grant research project: Poetry Standardization and Linked Open Data: POSTDATA (ERC-2015-STG-679528), funded by European Research Council (ERC) under the European Union's Horizon2020 research and innovation programme
The Impact of FDI on COâ Emissions in Latin America
This paper uses panel Granger causality tests to study the relationship between sector specific FDI and CO2 emissions. Using a sample of 18 Latin American countries for the 1980-2007 period, we find causality running from FDI in polluting intensive industries (âthe dirty sectorâ) to CO2 emissions per capita. This result is robust to controlling for other factors associated with CO2 emissions and using the ratio of CO2 emissions to GDP. For other sectors, we find no robust evidence that FDI causes CO2 emissions
