La reseña presenta el libro que K. Allan ha editado, The Oxford Handbook of the History of Linguistics (2013), en la colección de la Oxford University Press sobre Lingüística. En la obra participan más de treinta especialistas, que tratan de la historia en Occidente y, en menor medida, en Oriente. Los ámbitos de estudio respetan un orden tradicional: el sonido, la sintaxis y el significado y, como relativa novedad, la lingüística aplicada. Un interés complementario de la obra es su articulacíón en la amplia colección de manuales de lingüística.

The present article proposes Heathcliff and Sarah Woodruff as monstrous beings who reclaim their desire to be agent subjects in a society and a narrative which deny such a possibility. It would be possible to argue, however, that their monstrosity might be that of the unique specimen, the potential first stage towards the improvement of species through natural selection as theorized by Charles Darwin in 1859. The multiple references to Darwin’s study in the novel by JohnFowles demonstrate that such a theory could clarify what Sarah represents in the novel. In a retroactive manner, Darwinian theory might be used to understand what Heathcliff is, who Heathcliff is, and why he is the object of general animosity. It might be concluded that what is really monstrous about these twocharacters is that both are new specimens, avant la lèttre, and they occupy a space to which language has no access.

Improve the prediction of the vital and functional prognosis of comatose patients suffering from anoxic-ischemic encephalopathy after successful resuscitation from a cardiac arrest, addmitted to the Intensive Care and Coronary Units of the Dr. Josep Trueta Hospital, based on clinical, neurophysiological and biochemical results.The results of these different tests, revised and combined all together, will improve the prediction of the patients' prognosis, leading to an accurate vital and functional outcome, as they only have been studied separately so far. Anoxia is the third most frequent cause of coma, and the most common cause of post-anoxic coma in adults is the cardiac arrest. The incidence of hypoxic-ischemic brain injury is not well known, but it is certain that cardiac arrest, the most common cause of post-anoxic coma, affects approximately 24000 to 50000 Spanish people every year, most of them occuring out of the hospital. A cardiac arrest is the abrupt cessation of normal circulation of the blood due to failure of the heart to contract effectively during systole. It is different from, but may be caused by, a heart attack or myocardial infarction, where blood flow to the still-beating heart is interrupted. Arrested blood circulation prevents delivery of oxygen to all parts of the body. Cerebral hypoxia, or lack of oxygen supply to the brain, causes victims to lose consciousness and to stop normal breathing, although agonal breathing may still occur. Brain injury is likely if cardiac arrest is untreated for more than five minutes

En el cor embrional, la senyalització de mort cel•lular apoptòtica iniciada per receptors de mort i les caspases executores 3 i 7 exerceixen un paper important durant el desenvolupament cardíac no relacionat amb la mort cel•lular, i posteriorment són silenciats en l’adult, on les vies independents de caspases estan implicades en la mort cel•lular patològica. Resultats previs del nostre grup han contribuït a entendre com es regula i silencia en el cor l’expressió dels gens de la via apoptòtica depenent de caspases durant el desenvolupament; a més, resultats no publicats demostren que les caspases regulen el procés d’expressió de gens en el cor i, contràriament a la maquinària depenent de caspases, TatD, una nucleasa, ’expressa abundantment al cor postnatal. Es desconeixen les funcions de la senyalització apoptòtica durant el desenvolupament cardíac, tot i que són essencials per al desenvolupament, a més, la senyalització independent de caspases implicada al dany cel•lular en els miòcits només es coneix parcialment, el nostre objectiu és contribuir al coneixement d’ambdós fenòmens. Creiem que les caspases podrien processar proteïnes reguladores de l’expressió de gens musculars alterant la seva activitat, mentre que TatD té un paper rellevant en el dany cel•lular però també en la funció cardíaca normal. Volem caracteritzar la contribució de les caspases 3 i 7 en el desenvolupament cardíac, utilitzant models in vivo (estem finalitzant els creuaments necessaris per a disposar dels animals amb el genotip desitjat) i in vitro (pràcticament hem preparat tot el material i hem optimitzat els protocols per a tirar-ho endavant). També volem caracteritzar la funció de TatD durant el desenvolupament i fisiologia del cor i conèixer-ne la seva funció utilitzant models in vitro i in vivo.

Studies on the potential benefits of conveying biofeedback stimulus using a musical signal have appeared in recent years with the intent of harnessing the strong effects that music listening may have on subjects. While results are encouraging, the fundamental question has yet to be addressed, of how combined music and biofeedback compares to the already established use of either of these elements separately. This experiment, involving young adults (N = 24), compared the effectiveness at modulating participants' states of physiological arousal of each of the following conditions: A) listening to pre-recorded music, B) sonification biofeedback of the heart rate, and C) an algorithmically modulated musical feedback signal conveying the subject's heart rate. Our hypothesis was that each of the conditions (A), (B) and (C) would differ from the other two in the extent to which it enables participants to increase and decrease their state of physiological arousal, with (C) being more effective than (B), and both more than (A). Several physiological measures and qualitative responses were recorded and analyzed. Results show that using musical biofeedback allowed participants to modulate their state of physiological arousal at least equally well as sonification biofeedback, and much better than just listening to music, as reflected in their heart rate measurements, controlling for respiration-rate. Our findings indicate that the known effects of music in modulating arousal can therefore be beneficially harnessed when designing a biofeedback protocol.

Malgrat que la resistència específica del jugador té una influència directa sobre el rendiment en el tennis, un esport intermitent de llarga durada, les proves utilitzades per valorar-la no solen incloure tasques motrius properes a situacions de joc reals i poden ser considerades de baixa especificitat. L’objectiu d’aquest estudi és desenvolupar una prova de camp de valoració de la resistència específica en tennis (Specific Endurance Tennis Test, SET-Test), analitzant el comportament de la freqüència cardíaca (FC) i de paràmetres d’efectivitat tècnica (ET), per tal d’esbrinar una possible relació entre ambdós paràmetres i d’aquests amb el rendiment esportiu en jugadors de competició. Van participar set tennistes masculins, als quals els va ser administrada una prova triangular, progressiva, contínua i d’intensitat màxima conduïda per una màquina llançapilotes, durant la qual es va registrar la FC i, al mateix temps, paràmetres objectius d’ET (precisió i potència) mitjançant el càlcul de percentatge d’encerts i errors. S’observa un punt de deflexió de la FC (PDFC) en un 86 % dels subjectes estudiats, previ o coincident amb una disminució de l’ET (punt de deflexió de l’eficiència tècnica, PDET). Aquests dos punts mesurats de forma simultània al llarg de la prova es mostren relacionats amb el rendiment competitiu dels jugadors estudiats. Es conclou que la prova proposada sembla un mètode específic i vàlid per avaluar la resistència específica i la condició aeròbica en tennistes, tot i que calen més estudis per tal de confirmar les hipòtesis plantejades i la validesa externa de la prova.
