Tra terrore e prodigio: l’enfant terrible Fernando Arrabal
Il 5 ottobre del 1989 il drammaturgo Fernando Arrabal venne invitato a partecipare al programma televisivo noto come "La notte del millenarismo" ("La noche del milenarismo"), presentato da Fernando Sánchez Dragó. In quell’occasione, lo scrittore apparve ubriaco o sotto l’effetto di qualche sostanza che alterava il suo comportamento: l'episodio ha danneggiato la fama di Arrabal, da allora legata più alla sconfortante ‘performance’ televisiva che alla bontà delle sue creazioni; ma il drammaturgo non era nuovo alla confusione tra il ruolo di personaggio pubblico e le sue proiezioni artistiche.
Con la violenza e la crudeltà presenti nelle sue opere, Arrabal ha portato in scena le contraddizioni che hanno caratterizzato la Spagna del dopoguerra, partendo dalla sua esperienza personale. Il Caos che governa la confusione nelle sue opere si basa sullo stesso principio che gli ha procurato la fama di ‘enfant terrible’: nel momento in cui non si rispettano le norme, lo spazio organizzato del Cosmo viene invaso dal disordine e le conseguenze possono essere più o meno lievi (la caduta nel ridicolo, nel caso del passaggio televisivo, o l’inizio di una guerra civile)
Improving insect conservation across heterogeneous landscapes using species–habitat networks
Background: One of the biggest challenges in conservation is to manage multiple habitats for the effective conservation of multiple species, especially when the focal species are mobile and use multiple resources across heterogeneous protected areas. The application of ecological network tools and the analysis of the resulting species–habitat networks can help to describe such complex spatial associations and improve the conservation of species at the landscape scale. Methods: To exemplify the application of species–habitat networks, we present a case study on butterflies inhabiting multiple grassland types across a heterogeneous protected area in North-East Italy. We sampled adult butterflies in 44 sites, each belonging to one of the five major habitat types in the protected area, that is, disturbed grasslands, continuous grasslands, evolved grasslands, hay meadows and wet meadows. First, we applied traditional diversity analyses to explore butterfly species richness and evenness. Second, we built and analyzed both the unipartite network, linking habitat patches via shared species, and the bipartite network, linking species to individual habitat patches. Aims: (i) To describe the emerging properties (connectance, modularity, nestedness, and robustness) of the species–habitat network at the scale of the whole protected area, and (ii) to identify the key habitats patches for butterfly conservation across the protected area, that is, those supporting the highest number of species and those with unique species assemblages (e.g., hosting specialist species). Results: The species–habitat network appeared to have a weak modular structure, meaning that the main habitat types tended to host different species assemblages. However, the habitats also shared a large proportion of species that were able to visit multiple habitats and use resources across the whole study area. Even butterfly species typically considered as habitat specialists were actually observed across multiple habitat patches, suggesting that protecting them only within their focal habitat might be ineffective. Our species–habitat network approach helped identifying both central habitat patches that were able to support the highest number of species, and habitat patches that supported rare specialist species
Prognostic role of somatosensory and auditory evoked potentials in paediatric hypoxic-ischemic encephalopathy managed with hypothermia: An illustrative case
ntroduction: The contribution of clinical neurophysiology in the neurological prognosis of hypoxic-ischemic coma has been well established in adults: the bilateral absence of cortical somatosensory evoked potentials (SEP) is considered the single best indicator of adverse outcome, while the presence of the auditory mismatch negativity (MMN) is thought to herald arousal. Study aim: To use MMN combined with serial EEG recordings, somatosensory and brainstem auditory evoked potentials (BAEP) in a paediatric case of postanoxic coma managed with hypothermia, since they have not yet been described in children. Methods: We report the case of a nine-year-old boy with hypoxic-ischemic encephalopathy due to cardiorespiratory arrest after accidental burial in sand, who was treated with therapeutic hypothermia for 72 hours. Serial EEG recordings, evoked potentials, brain CT scan and brain MRI were performed in the first few days after the event. Results: SEP to median nerve stimulation showed bilateral absence of the N20 component, while the N13 and P14 peaks were preserved; BAEP showed normal I-V interpeak latency and normal hearing threshold. At the same time, the MMN component of auditory event related potentials, recorded in the classical oddball paradigm, was absent. Seventeen months after the accident, the patient is alive in persistent vegetative state. Conclusions: This case illustrates the particular significance of SEP and MMN together with EEG in gaining prognostic information, even in sedated and hypothermic patients, and encourages systematic study of these prognostic tools in paediatric postanoxic coma
Ricardo Menéndez Salmón
Ricardo Menéndez Salmón può essere inserito nella «Generación Nocilla», una definizione che racchiude una nomina di scrittori spagnoli nati tra il 1960 e il 1976, che iniziano a pubblicare intorno al 2006. L’estetica che accomuna gli autori di questa generazione attinge a piene mani dalla cultura pop, facendo del pastiche e del collage le tecniche più comuni, mentre i temi riflettono principalmente sulla frammentarietà e l’alienazione dell’individuo nella società contemporanea. In questo contesto si inserisce il suo romanzo "La ofensa"
The role of clinical neurophysiology in the Paediatric Intensive Care Unit
------The contribution of clinical neurophysiology to diagnosis, prognosis and monitoring of patients in the Paediatric Intensive Care Units is increasingly recognised. The EEG and the evoked potentials play only a limited role in determining a specific etiological diagnosis but these techniques are valuable in identifying several patterns of clinical relevance. The severity of EEG, evoked potential abnormalities and their timing of recovery have a fundamental role in supporting the neurological prognosis in terms of survival, awakening from coma, major or minor future disabilities in the neurological development. Dealing with young patients in their growth and maturing phase requires considering age before performing examinations and as a factor to interpret the test results, along with the wide spectrum of disorders that lead to coma in children. When dealing with comatose children a dynamic neurophysiology approach based on a continuous EEG monitoring can be combined with intermittent con..
Going Beyond Counting First Authors in Author Co-citation Analysis
The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
