Photosensitivity is a neurological condition in which the brain produces epileptic reactions known as Photoparoxysmal Responses (PPR) to certain visual stimuli, which may trigger epileptic seizures in the worst cases. This pathology is diagnosed through a standardized protocol called Intermittent Photic Stimulation consisting of stimulating the patient with a flashing light while recording the brain activity by Electroencephalogram (EEG) until a PPR is triggered. Due to the nature of the stimulation process and the photosensitivity’s low prevalence, the automatic detection of PPR becomes a highly unbalanced problem where PPR activity can be considered as anomalous activity surrounded by large portions of normal brain activity. This research proposes the use of a Variational Autoencoder (VAE) to extract features from the EEG segments by reducing them into the latent space to train several Anomaly Detection models proposed by the literature and compare their PPR detection performance. Results show that no AD model could detect any PPR activity correctly while the VAE model, also used for this task in our previous research, reached Accuracy, Sensitivity, and Specificity values of around 85%.

La revuelta contra el mundo moderno ha tomado variadas formas desde el movimiento romántico. Fue especialmente virulenta en el último tercio del siglo XIX en Alemania, donde los movimientos de juventud y los abundantes ocultistas proponían cosmovisiones alternativas al mundo industrializado y cientifista, al igual que en el movimiento nacionalsocialista. En el ocultismo contemporáneo y en las visiones alternativas de la New Age podemos hallar una interpretación o enfoque del ser humano y del cosmos semejante.The revolt against the modern world has taken varied forms since the Romantic Movement. It was especially virulent in Germany in the last third of the 19th century, where youth movements and the abundant occultists were proposing alternatives to the industrialized, science-oriented world, just like in the National Socialist movement. We can find a similar interpretation of the human being and of the cosmos in contemporary occultism and in the alternative visions of the New Age.

La Astrobiología se ha convertido desde la pasada década de los 90 en una de las disciplinas científicas con mayor impacto social. La posibilidad de que exista vida en otros lugares del universo se adivina cercana gracias a los avances en las técnicas de observación y a las próximas sondas que visitarán otros planetas y satélites de nuestro sistema solar. Las repercusiones de estos hipotéticos hallazgos son enormes para nuestra civilización. La Filosofía no puede quedarse al margen y deberá aportar su visión globalizadora ante un fenómeno fundamental en la historia humana

La oposición entre Democracia y Liberalismo tiene su punto de tensión en la relación vida pública-vida privada. Para Roger Labrousse, la Democracia hace depender la vida privada del hombre de su vida pública, en tanto que para el Liberalismo la vida privada se antepone a la vida pública. Se trata de dos extremos que se articulan de modo complejo, a veces como complemento y a veces como conflicto. No podría ser de otro modo. Normalmente estas dicotomías tienen en una primera mirada una apariencia de claridad, que rápidamente en un análisis más exigente comienza a desdibujarse. En este artículo se reproducen algunos párrafos seleccionado de cinco autores seleccionados a los que se hace un breve comentario, teniendo en cuenta principalmente la oposición entre Democracia y Liberalismo. En cada caso el comentario busca mostrar la debilidad de la reflexión cuando se despliega sobre el fondo de esta oposición en términos demasiado rígidos

Resumen. El presente estudio de caso expone, a partir de la historia de vida como fuente de información, un abordaje de la vida cotidiana más allá de lo meramente narrativo y periodístico. La investigación toma como objeto de estudio los cambios ocurridos en las costumbres y los hábitos de comportamiento cotidiano de una inmigrante española en la colonia agrícola de Turén en Venezuela a mediados del siglo pasado. Se considera que los procesos migratorios, máxime si se enmarcan dentro de un proyecto colonizador, resultan propicios para detectar las variaciones en los mun-dos vitales de las personas, en ese proceso obligado al que se enfrenta el emigrante de ajustarse a las condiciones de un medio ambiente nuevo, extraño y a veces per-cibido como hostil. La información se recoge a través de los recuerdos que tiene la emigrante, suministrados en entrevistas abiertas. Las experiencias de la vida cotidiana en el pueblo español donde vivía la emigrante se comparan con las de la colonia agrícola venezolana a la que fue a vivir, a la luz de aportes teóricos provenien-tes del campo de la antropología. Se concluye que el enfoque etnohistórico de los hechos puede contribuir a explicar el análisis histórico de los mismos, dando una visión alternativa pero complementaria y enriquecedora a las metodologías tradi-cionales para el estudio del pasado. Palabras clave: etnohistoria, vida cotidiana, historia de vida, inmigración, siglo XX, Aragón, Venezuela.. The essay exposes a study of the daily life, trying to overcome the normal, journalis-tic narrative explanations, offering instead an approach based on the history of life-time. The research takes as object of study the expected changes occurred in the personal manners and daily habits of a Spanish immigrant in the agricultural colony of Turen in Venezuela, during the middle of the past century. Migration processes, especially if happen as part of colonization projects, offer a good opportunity to detect relevant changes in the inner lives of people, due to the efforts of the immi-grant to deal with the adaptation to a new, different and sometimes hostile environ-ment. Information is obtained through the remembrances of the immigrant during open interviews. Personal remembrances about her daily life in the small Spanish town where she lived before migration are compared with those other ones in the Venezuelan agricultural colony where she arrived. These comparisons are analysed based on contributions coming from the anthropology field. As a conclusion, etno-history approach is recommended for the study of the past in order to enrich tradi-tional methodologies used by historians, as a complementary approach. Key words: etnohistory, daily life, history of lifetime, immigration, 20th century, Aragon, Venezuela.

Objectives To develop and test two educational programmes (interactive and passive) aimed at improving family doctors' (FD) prescribing practices and patient's knowledge and use of non-opioid analgesics (NOA).Methods The educational programmes were conducted in two family medicine clinics by using a three-stage approach: baseline evaluation, design, and implementation of educational activities, and post-programme evaluation. An interactive educational programme (IEP) was compared with a passive educational programme (PEP); both were participated by FDs and patients. The IEP for FDs comprised of workshops, discussion groups, in-service training and guidelines, while for patients the IEP consisted of an interactive session with a video, leaflets and a discussion. The PEP consisted in delivering the guidelines to the FDs and the leaflets to patients. The effect of the programmes on the FDs was measured through the appropriateness of prescriptions and analysed using the differences-in-differences estimator (D-in-D), and on patients through changes in self-medication and in their knowledge about the proper use and adverse events by analysing the inter- and intra-group differences before and after the programmes.Results The IEP obtained better results to improve appropriate FDs prescription of NOA than PEP (D-in-D = 15%). Regarding the patients, the PEP group reached higher reduction of self-medication than the IEP group (13.4% vs. 9.1%); the knowledge of proper NOA use increased by 8.5% in both groups, whereas knowledge of NOA-related adverse events was better in the IEP (39.6%) than in the PEP group (9.2%).Conclusions The IEP was better to improve the doctors' abilities to prescribe NOAs, and both programmes improved patients' knowledge.
