El sistema electoral de les Corts Valencianes: orígens i reforma

[cat] Aquest article vol refutar la hipòtesi que els partits decideixen sistemes electorals majoritaris i que decideixen també mantenir-los invariables, sempre que el sistema de partits s"aproximi al bipartidisme i cap dels dos grans partits pugui perdre la seva posició a favor d"un nou competidor. De manera inversa, els sistemes electorals proporcionals són la conseqüència del multipartidisme, en el qual cap partit té opcions de rebre la majoria dels vots. El cas valencià, però, confirma només parcialment la hipòtesi: els partits van aprovar el 1982 regles proporcionals perquè les eleccions dels parlaments autonòmics eren considerades secundàries, no només pel multipartidisme existent aleshores. En canvi, sí que es confirma que el canvi iniciat el 2006 amb la reforma estatutària manté, de moment, l"status quo per no alterar la formació de majories parlamentàries. Encara queda pendent, però, que es modifiqui la Llei Electoral, de la qual depèn quin mínim de vots per entrar a les Corts s"establirà.

Sensorimotor Plasticity after Music-Supported Therapy in Chronic Stroke Patients Revealed by Transcranial Magnetic Stimulation

BACKGROUND: Several recently developed therapies targeting motor disabilities in stroke sufferers have shown to be more effective than standard neurorehabilitation approaches. In this context, several basic studies demonstrated that music training produces rapid neuroplastic changes in motor-related brain areas. Music-supported therapy has been recently developed as a new motor rehabilitation intervention. METHODS AND RESULTS: In order to explore the plasticity effects of music-supported therapy, this therapeutic intervention was applied to twenty chronic stroke patients. Before and after the music-supported therapy, transcranial magnetic stimulation was applied for the assessment of excitability changes in the motor cortex and a 3D movement analyzer was used for the assessment of motor performance parameters such as velocity, acceleration and smoothness in a set of diadochokinetic movement tasks. Our results suggest that the music-supported therapy produces changes in cortical plasticity leading the improvement of the subjects' motor performance. CONCLUSION: Our findings represent the first evidence of the neurophysiological changes induced by this therapy in chronic stroke patients, and their link with the amelioration of motor performance. Further studies are needed to confirm our observations.

Història i Comunitat Popular a l’Alemanya Nazi

El projecte pretén esdevenir l’anàlisi sobre quin fou el rol que assumí la història –a nivell institucional, educatiu i popular– en la configuració del Tercer Reich, apuntant doncs principalment a descobrir quina funció va tenir aquesta en la construcció de la nació alemanya durant els anys trenta. La hipòtesi que servirà de punt de partida de la investigació serà concebre que la història es convertí en una eïna que únicament es debia a l’estat per així poder reforçar la construcció del règim nacionalsocialista alemany. L’estudi es dedicarà per tant a haver de demostrar tal afirmació.

August i la política d'entreteniment popular: la construcció d'edificis d'espectacles durant l'època augustal.

Quan August va accedir al poder en solitari l'any 31 aC, Roma es trobava trastornada per un seguit de guerres civils que havien deixat l'Estat molt malparat. A partir d'aquell moment, el principal objectiu d'August va ser el retorn a la normalitat, assegurar les necessitats del poble i consolidar el règim que acabava d'inaugurar. No en va, aquest emperador presumia d'haver trobat una Roma de maons i haverla deixat de marbre. August va assumir una bona part de les despeses que generava aquesta política com si fos un veritable deure personal. Gràcies a la immensa fortuna heretada de Juli Cèsar, August va poder finançar aquells aspectes de la vida pública que més atreien els seus contemporanis. El primer ciutadà de l'Imperi es converteix també en el primer evergeta (benefactor) amb un propòsit ben interessat: captar el favor popular.

Using music as a signal for biofeedback

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.

Plasticity in the sensorimotor cortex induced by Music-supported therapy in stroke patients: a TMS study.

Playing a musical instrument demands the engagement of different neural systems. Recent studies about the musician"s brain and musical training highlight that this activity requires the close interaction between motor and somatosensory systems. Moreover, neuroplastic changes have been reported in motor-related areas after short and long-term musical training. Because of its capacity to promote neuroplastic changes, music has been used in the context of stroke neurorehabilitation. The majority of patients suffering from a stroke have motor impairments, preventing them to live independently. Thus, there is an increasing demand for effective restorative interventions for neurological deficits. Music-supported Therapy (MST) has been recently developed to restore motor deficits. We report data of a selected sample of stroke patients who have been enrolled in a MST program (1 month intense music learning). Prior to and after the therapy, patients were evaluated with different behavioral motor tests. Transcranial Magnetic Stimulation (TMS) was applied to evaluate changes in the sensorimotor representations underlying the motor gains observed. Several parameters of excitability of the motor cortex were assessed as well as the cortical somatotopic representation of a muscle in the affected hand. Our results revealed that participants obtained significant motor improvements in the paretic hand and those changes were accompanied by changes in the excitability of the motor cortex. Thus, MST leads to neuroplastic changes in the motor cortex of stroke patients which may explain its efficacy.

Analyzing hidden semantics in social bookmarking of open educational resources

Web 2.0 services such as social bookmarking allow users to manage and share the links they find interesting, adding their own tags for describingthem. This is especially interesting in the field of open educational resources, asdelicious is a simple way to bridge the institutional point of view (i.e. learningobject repositories) with the individual one (i.e. personal collections), thuspromoting the discovering and sharing of such resources by other users. In this paper we propose a methodology for analyzing such tags in order to discover hidden semantics (i.e. taxonomies and vocabularies) that can be used toimprove descriptions of learning objects and make learning object repositories more visible and discoverable. We propose the use of a simple statistical analysis tool such as principal component analysis to discover which tags createclusters that can be semantically interpreted. We will compare the obtained results with a collection of resources related to open educational resources, in order to better understand the real needs of people searching for open educational resources.
