    La nueva historia política de la educación ha buscado nuevos caminos de análisis. Desde esta perspectiva, queremos abordar el concepto de Estado y queremos reflejar las distintas ideas y posturas que se iban postulando a lo largo de un periodo rico en cambios políticos, sociales y económicos que van a ir influyendo directamente en la Educación. En este caso concreto, lo vamos a hacer desde lo que escribe lorenzo Luzuriaga en el suplemento dedicado a Pedagogía e Instrucción Pública del periódico El Sol de corte liberal y reformista, este diario fue considerado uno de los mejores de Europa y el mejor de España durante muchos años. Se publicó desde diciembre de 1917 hasta marzo de 1939. El suplemento de Pedagogía e Instrucción Pública se publicaba los lunes y en este se iba comentando la actualidad de la educación del momento tanto a nivel nacional como internacional, aunque él colaboró sólo hasta 1921. El objetivo de la comunicación es hacer un recorrido por la legislación, planes de estudio, aspiraciones, logros y desengaños de la Educación en España a través de un pedagogo e intelectual de la talla de Lorenzo Luzuriaga. Respecto a la metodología, vamos a utilizar fundamentalmente las fuentes primarias, ya que vamos a analizar la información publicada en el Suplemento de Pedagogía e Instrucción Pública a lo largo de estos años previos a la Dictadura de Primo de Rivera. Los resultados van a ahondar en las ideas y concepciones sobre el Estado y sus relaciones a lo largo del periodo de estudio es una tarea iniciada desde una mirada general, y que nos invita a seguir desde las diferentes perspectivas que el estudio abre, que son muchas. Sin duda, el escenario político se convierte en una mirada necesaria para poder comprender el final de un proceso que queda plasmado en la legislación educativa.Universidad de Málaga.

    Coulomb dissociation of O-16 into He-4 and C-12

    We measured the Coulomb dissociation of O-16 into He-4 and C-12 within the FAIR Phase-0 program at GSI Helmholtzzentrum fur Schwerionenforschung Darmstadt, Germany. From this we will extract the photon dissociation cross section O-16(alpha,gamma)C-12, which is the time reversed reaction to C-12(alpha,gamma)O-16. With this indirect method, we aim to improve on the accuracy of the experimental data at lower energies than measured so far. The expected low cross section for the Coulomb dissociation reaction and close magnetic rigidity of beam and fragments demand a high precision measurement. Hence, new detector systems were built and radical changes to the (RB)-B-3 setup were necessary to cope with the high-intensity O-16 beam. All tracking detectors were designed to let the unreacted O-16 ions pass, while detecting the C-12 and He-4

    Marine Biodiversity in the Caribbean: Regional Estimates and Distribution Patterns

    This paper provides an analysis of the distribution patterns of marine biodiversity and summarizes the major activities of the Census of Marine Life program in the Caribbean region. The coastal Caribbean region is a large marine ecosystem (LME) characterized by coral reefs, mangroves, and seagrasses, but including other environments, such as sandy beaches and rocky shores. These tropical ecosystems incorporate a high diversity of associated flora and fauna, and the nations that border the Caribbean collectively encompass a major global marine biodiversity hot spot. We analyze the state of knowledge of marine biodiversity based on the geographic distribution of georeferenced species records and regional taxonomic lists. A total of 12,046 marine species are reported in this paper for the Caribbean region. These include representatives from 31 animal phyla, two plant phyla, one group of Chromista, and three groups of Protoctista. Sampling effort has been greatest in shallow, nearshore waters, where there is relatively good coverage of species records; offshore and deep environments have been less studied. Additionally, we found that the currently accepted classification of marine ecoregions of the Caribbean did not apply for the benthic distributions of five relatively well known taxonomic groups. Coastal species richness tends to concentrate along the Antillean arc (Cuba to the southernmost Antilles) and the northern coast of South America (Venezuela – Colombia), while no pattern can be observed in the deep sea with the available data. Several factors make it impossible to determine the extent to which these distribution patterns accurately reflect the true situation for marine biodiversity in general: (1) highly localized concentrations of collecting effort and a lack of collecting in many areas and ecosystems, (2) high variability among collecting methods, (3) limited taxonomic expertise for many groups, and (4) differing levels of activity in the study of different taxa

    A Common Solution for Tokenization and Part-of-Speech Tagging: One-Pass Viterbi Algorithm vs. Iterative Approaches

    No full text
    Current taggers assume that input texts are already tokenized, i.e. correctly segmented in tokens or high level information units that identify each individual component of the texts. This working hypothesis is unrealistic, due to the heterogeneous nature of the application texts and their sources. The greatest troubles arise when this segmentation is ambiguous. The choice of the correct segmentation alternative depends on the context, which is precisely what taggers study. In this work, we develop..
