Una noticia publicada en The Sun en 1844 narraba que un globo aerostático había sido capaz de cruzar el océano Atlántico por primera vez. Sin embargo, lo que debería haber sido un hito para la historia de la humanidad no era más que un bulo difundido por el escritor Edgar Allan Poe. Así, este trabajo tiene como finalidad analizar el relato “El engaño del globo”, enfatizando sus orígenes, su repercusión y las fuentes que inspiraron al autor en la creación de una historia clave para el género de la ciencia ficción.

[ES] Los estudios de caso que integran el presente monográfico analizan muestras de las diversas transformaciones que se han venido llevando a cabo en el género gótico desde los años 70 hasta la actualidad en los ámbitos de la ficción, las artes visuales y otras formas de cultura popular. Se hace especial énfasis en los patrones de influencia, apropiación y reformulación, así como en la continuidad del imaginario gótico en la posmodernidad. Se invita así a la reflexión sobre las ansiedades del mundo contemporáneo y su reflejo o expresión en las diferentes manifestaciones artísticas y literarias del género del terror., [EN] The case studies in this volume assess the transformations undergone by the Gothic genre since the 1970s until today within the fields of fiction, the visual arts and other forms of popular culture. Special emphasis falls into the patterns of influence, appropriation and reformulation in the works under assessment, as well as the durability of gothic imagery in postmodernity. We thereby invite readers to reflect on how these visual and literary works echo, reflect or give voice to the anxieties in our contemporary society.

This article presents a model for the analysis of data on the Internet, using Web mining, to find knowledge about large amounts of information in cyberspace. To test the proposed method, Web pages on Cyberbullying were analyzed as a case study. The procedure integrates a Web Scraper to locate and download information from the Internet, to recover the vocabulary are used techniques of Natural Language Processing (tokenization, cleaning of words without meaning, frequency of term, inverse frequency of the document, synonyms, stemming methods). To obtain knowledge, a dataset was constructed using semantic ontologies to define the predictive variables of Cyberbullying and supervised learning to define the variable to be predicted. To evaluate the efficiency of the model, algorithms of machine learning, AdaBoost and Neural Network were used. The results reveal a percentage of 97% accuracy in the detection of Cyberbullying vocabulary, which was approved through crossvalidation, achieving a time saving of 581% with parallel processing, compared to sequential processing.

The interdisciplinary and consolidated research group “LyA” (Literature & Art) of the University of Castilla-La Mancha was established in 2015, being granted by the Spanish Ministerio de Economia y Competitividad for the development of a four-year research project: “Poe On-line: Text and Image” (HAR2015-64580-P). Among the main goals of this project, co-directed by Prof. Dr. Rigal-Aragon (Dep. of Modern Philology) and Prof. Dr. Gonzalez-Moreno (Dep. of History of Art), we must highlight the design and implementation of an online catalogue able to offer public access to most of the illustrated editions of Edgar A. Poe’s works. This paper will present the current state of this database as well as some of our future and priority lines of action. The IT tool able to catalogue our textual and illustrated materials has already been designed and developed, generating a highly customized device for our purposes. The database is centered on three different and interconnected databanks: 1) Databank “Works”, which allows us to establish a taxonomy of Poe’s complete works and related materials (tales, novels, poems, theoretical texts, others –biographies, documents, preliminary studies, introductions, teaching materials, prologues, prefaces). 2) Databank “Editions”, which includes 14 fields to catalogue the illustrated editions that the research group is collecting to create our specific collection: title, author, language, publication place, kind of edition (original version, adaptation in English, translation, children’s edition, anthology…), year, volumes, number of pages, size, publishing house, translator, library, biographical references, description; once that the edition is created, we can link to its entry the tales, poems, or works included in the edition according to its index, indicating if they are illustrated too. 3) Databank “Illustrations”, which allows us to catalogue each of the images included in the editions according to a form with 13 different fields: edition, work, title, image (pre-scanned illustration of 600 ppp), illustrator, engraver, volume, page, illustration measures, page measures, color, notes, and technique. Then, each illustration is tagged following a pre-established taxonomy of the relevant characters, places, plants, animals, and objects included in each tale, poem, or work. And finally, it is linked to the part of the text that it illustrates; in order to accomplish this, we have pre-established a structure/division for each tale, poem or work. Thanks to this research project, we expect to create a multilayer online catalogue-edition that will allow the user to read Edgar A. Poe’s works combining his texts with the most relevant visual readings. The user will be able to browse our catalogue exploring these materials in several directions: from the illustrations to the texts and vice versa; selecting a specific tale, poem, or work and deciding the illustrations that should accompany it; comparing the different interpretations that the illustrators (Coburn, Rackham, Dulac, Dore, Beardsley, Grimly, etc.) have elaborated since mid-nineteenth century till nowadays; etc. Presently, we are dedicated to upload and catalogue these textual and visual materials, anticipating that the public access to the database will be ready in less than a year. In this way, we expect to create an online didactic resource of a high level and to promote the knowledge of the reception that Poe’s works have had in Spain.

Background: Blood transfusion safety is based on reliable donor screening for transmissible infections such as the hepatitis C virus (HCV) infection. Study design and methods: A novel HCV core-specific antibody was assayed on random single donations from 2007 first-time blood donors who tested negative for anti-HCV and HCV RNA on routine screening. Sample collection broke the code between donations and donors for ethical reasons. Results: Forty-two donations (2.1%) displayed reactivity in the novel test. The specificity of the reactivity was evaluated by a peptide inhibition assay, and testing against additional nonoverlapping HCV core peptide epitopes and other HCV antigens was performed on these samples. Six donations (14.3%; 0.30% from the total) were considered to contain anti-HCV after such supplemental testing. HCV RNA detection was also performed in peripheral blood mononuclear cells (PBMNCs) and serum or plasma samples from reactive donors after virus concentration by ultracentrifugation. HCV RNA tested negative in all PBMNCs samples, and a very low amount of viral genome was detected in serum or plasma concentrates from three anti-HCV core-reactive donors (7.1%) but not among concentrates from 100 randomly selected nonreactive donors. Sequencing of these polymerase chain reaction products revealed differences between the isolates that excluded partially sample contamination from a common source. Conclusion: These findings argue in favor of an ongoing occult HCV infection among these blood donors and account for some rather low, but perhaps not negligible, infection risk for such donations. Future studies involving larger samples of donations from traceable donors would enlighten the significance of these findings for the viral safety of the blood supply.
