Biodiversity continues to decline in the face of increasing anthropogenic pressures such as habitat destruction, exploitation, pollution and introduction of alien species. Existing global databases of species' threat status or population time series are dominated by charismatic species. The collation of datasets with broad taxonomic and biogeographic extents, and that support computation of a range of biodiversity indicators, is necessary to enable better understanding of historical declines and to project - and avert - future declines. We describe and assess a new database of more than 1.6 million samples from 78 countries representing over 28,000 species, collated from existing spatial comparisons of local-scale biodiversity exposed to different intensities and types of anthropogenic pressures, from terrestrial sites around the world. The database contains measurements taken in 208 (of 814) ecoregions, 13 (of 14) biomes, 25 (of 35) biodiversity hotspots and 16 (of 17) megadiverse countries. The database contains more than 1% of the total number of all species described, and more than 1% of the described species within many taxonomic groups - including flowering plants, gymnosperms, birds, mammals, reptiles, amphibians, beetles, lepidopterans and hymenopterans. The dataset, which is still being added to, is therefore already considerably larger and more representative than those used by previous quantitative models of biodiversity trends and responses. The database is being assembled as part of the PREDICTS project (Projecting Responses of Ecological Diversity In Changing Terrestrial Systems - http://www.predicts.org.uk). We make site-level summary data available alongside this article. The full database will be publicly available in 2015.

Nontypeable Haemophilus influenzae (NTHI) is an opportunistic pathogen that is an important cause of acute exacerbations of chronic obstructive pulmonary disease (AECOPD). COPD is an inflammatory disease of the airways, and exacerbations are acute inflammatory events superimposed on this background of chronic inflammation. Azithromycin (AZM) is a macrolide antibiotic with antibacterial and anti-inflammatory properties and a clinically proven potential for AECOPD prevention and management. Relationships between AZM efficacy and resistance by NTHI and between bactericidal and immunomodulatory effects on NTHI respiratory infection have not been addressed. In this study, we employed two pathogenic NTHI strains with different AZM susceptibilities (NTHI 375 [AZM susceptible] and NTHI 353 [AZM resistant]) to evaluate the prophylactic and therapeutic effects of AZM on the NTHI-host interplay. At the cellular level, AZM was bactericidal toward intracellular NTHI inside alveolar and bronchial epithelia and alveolar macrophages, and it enhanced NTHI phagocytosis by the latter cell type. These effects correlated with the strain MIC of AZM and the antibiotic dose. Additionally, the effect of AZM on NTHI infection was assessed in a mouse model of pulmonary infection. AZM showed both preventive and therapeutic efficacies by lowering NTHI 375 bacterial counts in lungs and bronchoalveolar lavage fluid (BALF) and by reducing histopathological inflammatory lesions in the upper and lower airways of mice. Conversely, AZM did not reduce bacterial loads in animals infected with NTHI 353, in which case a milder anti-inflammatory effect was also observed. Together, the results of this work link the bactericidal and anti-inflammatory effects of AZM and frame the efficacy of this antibiotic against NTHI respiratory infection.

Juan Mayorga’s La Lengua en Pedazos (2010) strikes at the heart of the compositional circumstances of St Teresa's Libro de la Vida– staging, and arguably heightening the origins of her rhetorical strategies, the sense of awareness of readership and potential censure we encounter within the Libro de la Vida. His inquisitor refuses to be complicit in the tacit agreement that the word spoken in the theatrical space can conjure new realities –insistent on underscoring the textual origin of the visions painfully and partially offered up for his and our scrutiny. I will suggest that the persistent undertow towards a meta-commentary on the unmaking and remaking of the autobiographical text creates an unresolved tension between Teresa’s eloquent ability to take the spectator to a place beyond language, and our awareness that we are in the presence of a consummate performer, the textual source for the script itself produced with a supreme awareness of audience scrutiny. The play reflects ongoing lines of inquiry in our evolving understanding of the cultural production of Teresa and other holy women of the Early Modern period.

La manía del bibliófilo suele convertirse en un laberinto de ese tipo de encuentros fortuitos que los ingleses del siglo XVIII llamaron “serendipity”. En este ensayo, gracias a mis incursiones bibliofílicas en el ámbito de la literatura aurisecular, salió a flote un precedente muy probable del haikú hispánico (aceptada la relatividad de su parentesco con el haikú japonés) en otras formas casi ideográficas de la poesía que se cultivó siglos muy anteriores al modernismo. En este caso se trata de pequeñas estrofas que acompañaban sendos grabados, cuyos motivos emblemáticos obligaban a una expresión sintética y profundamente visual, casi gestual. En un estudio paralelo, cotejo los Jeroglíficos de Alonso de Ledesma con algunos hai-kai de José Juan Tablada, separados por una distancia de tres siglos, pero identificados en su búsqueda poética.

l seminario sigue la línea establecida en el curso sobre los “Clásicos de la literatura de la metrópolis” impartido durante el semestre de 2008-2. En este semestre, se analizan novelas, cuentos, crónicas y películas latinoamericanos producidos a partir de 1960. Interpretamos textos desde el ciclo novelístico de Santa María, de Juan Carlos Onetti, pasando por el llamado boom de la década de 1960 (Guillermo Cabrera Infante, Julio Cortázar) y las crónicas mexicanas de los años 70 y 80 (Carlos Monsiváis, Cristina Pacheco, Elena Poniatowska) hasta llegar al análisis de novelas y cuentos más recientes de autores como Carmen Boullosa, Guillermo Fadanelli, Juan Forns, Ricardo Piglia, Guillermo Samperio, Fernando Vallejo, Rafael Ramírez Heredia. Además, analizamos películas recientes como: El callejón de los milagros, La virgen de los sicarios, Ciudade de Deus y Amores perros.

This study presents and discusses the tsunami hazard posed by an updated CSZ earthquake scenerio to the coastal communities of Port Angeles and Port Townsend, based on the results of a high resolution GeoClaw simulation with 2/3 arc second resolution (about 20.56 meters) surrounding these towns. In addition, we will also present the results of a coarse regional simulation of the Strait of Juan de Fuca. This coarse study encompasses 28 regions that span the Strait’s coast, including the communities of Anacortes, Bellingham, Friday Harbor, and Victoria, BC in addition to extended areas around Port Angeles and Port Townsend. The finest grid for these 28 regions where we collected results had 2 arc sec resolution (around 62 meters). Finally, we will discuss some inherent uncertainties in the specification of the earthquake scenario, the limitations of the GeoClaw model, and the associated uncertainites in the results.

Através da análise comparativo/intertextual do conto Don Juan, de E.T.A. Hoffmann e do libreto da ópera Don Giovanni, de Mozart, da autoria de Lorenzo da Ponte, o objectivo deste artigo foi pôr em relevo a relação intrínseca, presente em muitas das obras de E.T.A. Hoffmann, entre a escrita e a música, explicável pela enorme sensibilidade musical deste autor, a que não só dedicou a sua vida, como também produziu várias obras musicais. Tal como na ópera Don Giovanni, de Mozart, a escrita de Hoffmann é dirigida por uma batuta imaginária, apresentando o suspense próprio dos enigmas, cuja revelação é suspensa por um entreacto – neste caso, uma carta escrita a um amigo, em que nos é apresentada uma reformulação do mito de Don Juan – entreacto este que vem prolongar o mistério e nos encaminha para um finale, em que a progressão da melodia e a sequência narrativa se unem mais uma vez. Por seu turno, na análise puramente intertextual, é feita uma tentativa de estabelecer, de forma clara, os paralelismos existentes com o pré-texto, isto é, com o libreto da autoria de Lorenzo da Ponte, bem como com outros pré-textos presentes no texto de forma mais esbatida, mas cujo peso é, também ele, significativo para a criação do novo mito de Don Juan, um homem sempre consciente do absurdo da existência, interpretação esta que abriu caminho para novas abordagens do mito, do herói e da história. Tal como em muitas outras obras, o pós-texto procura, em geral, apropriar-se do texto pressuposto, tentando ultrapassá-lo em mestria, o que acontece com este texto de Hoffmann, literária e semanticamente mais rico que o seu pré-texto.

Estudio Línea Base – ELBA Callao, primavera 2011. Inf Inst Mar Perú. 39(3-4): 149-198.- El ELBA se efectuó en el área delimitada por las islas San Lorenzo y El Frontón y la Península de La Punta, del 21 al 30 de noviembre 2011, para a) caracterizar biológica y oceanográficamente el área de estudio y b) obtener bases técnicas para el ordenamiento pesquero y acuícola. En el área predominaron sedimentos arenosos y grava de origen terrígeno. Presentó características térmicas frías al interior y cálidas al sur, con influencia de aguas costeras. La comunidad fitoplanctónica presentó abundancia de diatomeas. Se identificó zonas con alta biomasa de bentos y con altos valores de stress. Los sólidos suspendidos totales, cadmio y coliformes totales y termotolerantes sobrepasaron los límites de los estándares de calidad acuática en el Perú. Las comunidades de invertebrados más importantes fueron: concha de abanico Argopecten purpuratus, cangrejos Cancer setosus (ahora Romaleon polyodon) y C. porteri, almeja Semele spp., pulpo Octopus mimus y macroalga Macrocystis sp.; el calamar Loligo gahi usa el área para desovar.
