Considérations méthodologiques Nous avons limité aux précisions indispensables à la compréhension de notre propos les considérations sur la gigantomachie en général. Nous renvoyons aux études signalées plus haut (supra, p. 7, n. 2), principalement pour ce qui concerne les géants avant leur transformation en anguipèdes à partir de l'époque hellénistique. Notre recherche de parallèles reposera sur quelques oeuvres d'art encore existantes : les sculptures décorant les plus importantes d'entre elles feront dès lors figure d'archétype, même si, bien sûr, rien ne permet d'exclure qu'il en ait existé de plus significatives. Parmi les nombreux monuments aujourd'hui disparus, respectivement parmi ceux qui seraient encore à découvrir, il s'en trouvait sans doute qui auraient été susceptibles de servir de modèle pour les sculptures ornant le fanum de Lousonna, duquel bien peu de restes nous sont parvenus. A l'exception de quelques renvois ponctuels, notre démarche s'est appuyée exclusivement sur du matériel et des informations déjà publiés. Pour la reconstitution des bas-reliefs de Lousonna, nous nous sommes inspiré généralement de sculptures hellénistiques et romaines dont l'ornementation présentait des similitudes avec les fragments à notre disposition ; la plupart des parallèles sont mentionnés dans le Lexicon Iconographicum Mythologiae Classicae. L'examen des volumes du Corpus Signorum Imperii Romani et de quelques autres recueils nous a permis de faire des propositions pour les cas restés en suspens. A une exception près, l'échantillonnage aéré formé à partir d'ensembles sculptés qui devaient avoir les mêmes caractéristiques que le matériel que nous tenterons d'identifier : ils comportaient des monstres anguipèdes avec les jambes se terminant par la tête du serpent, remontant au plus tard à la fin de la période romaine et produits dans un atelier gréco-romain. Afin de recréer avec le plus de vraisemblance possible l'environnement du fanum de Lousonna, nous avons recherché des édifices de caractéristiques semblables dans les catalogues de temples gallo-romains dressés par P. D. HORNE et A. C. KING (1980), respectivement I. FAUDUET et P. ARCELIN (1993). Tant l'absence presque complète de restes architecturaux susceptibles d'être rapportés à l'édifice religieux que la nature somme toute modeste du vicus lémanique nous ont fait opter pour une variante minimaliste, se limitant finalement à la structure supportant la gigantomachie devant un temple sans aucune décoration. Pour tenter de préciser les modalités de la transmission du thème des géants, nous envisagerons trois cheminements possibles : la tradition orale, la transmission littéraire et, enfin, la représentation iconographique, qu'il s'agisse de monuments, d'objets mobiliers ou même des quelques rares illustrations de textes antiques. Sauf indication contraire, les textes anciens sont cités dans les traductions des Belles-Lettres, des Sources chrétiennes ou de la Loeb Classical Library dont la liste figure à la page 161. La version française des textes dont aucune traduction n'était disponible est généralement due à François Mottas (traduction F.M.). Nous ne reportons les dates de naissance des auteurs ou des artistes mentionnés que lorsqu'elles sont utiles à la compréhension de notre exposé. En plus du rôle qu'ont pu jouer les oeuvres d'art disparues au cours des deux derniers millénaires, divers facteurs ont dû assurer la constitution et la mise au point d'un imaginaire de plus en plus élaboré des gigantomachies. La mémoire a certes sa part dans l'inspiration des artistes qui réalisèrent les sculptures de la cité lémanique; mais si un mythe ou le récit d'un événement peuvent s'être transmis de bouche à oreille au cours des siècles, certaines ressemblances dans l'attitude des personnages sont trop frappantes, même en tenant compte de ces gestes qu'il n'existe qu'une seule façon de représenter: il n'est dès lors pas possible d'imaginer que la transmission des détails des scènes se serait pratiquée uniquement par voie orale. Si le voyage touristique; tel que nous l'entendons de nos jours, n'a pas existé, les personnes susceptibles d'avoir ramené des informations de leurs déplacements à travers l'Empire sont plus nombreuses qu'on ne le croirait au premier abord. Fonctionnaires allant prendre leur charge ou en mission dans une contrée voisine; soldats, parmi lesquels des mercenaires gaulois; pèlerins ayant visité de grands sanctuaires, comme celui d'Esculape à Pergame, emplacement de la gigantomachie la plus impressionnante, ou d'autres lieux de culte; jeunes fortunés ayant étudié à Athènes; commerçants accompagnés par des muletiers ou des portefaix acheminant leurs marchandises; membres de corporations ou artisans exerçant des métiers itinérants; esclaves, dont l'exportation devait représenter une source de revenus intéressante pour les commerçants romains; en dernier lieu, sans parler des artistes eux-mêmes, ces arpenteurs-géomètres chargés de toutes sortes de relevés qui accompagnaient les empereurs lors de leurs déplacements (infra, p. 36). Il faudra cependant rester prudent quant à l'affirmation d'une connaissance visuelle directe que les sculpteurs de Lousonna auraient eue des réalisations antiques avec lesquelles nous mettrons la gigantomachie en parallèle. Même si elle n'a toujours pas pu être prouvée, la circulation de cahiers de modèles semble bel et bien assurée: dans un atelier, les maîtres ont forcément passé leurs croquis à leurs successeurs et ceci s'est peut-être répété pour plusieurs générations d'artisans. Sans parler des monnaies, d'autres moyens de transmission peuvent encore être mentionnés : éventuelles éditions illustrées de textes antiques, motifs gravés sur des gemmes ou représentés sur des récipients décorés... Une observation s'impose ici : la plupart des monuments que nous utiliserons pour notre reconstitution existaient encore lors de l'érection de notre gigantomachie. Une fois les bas-reliefs de Lousonna reconstitués, restait donc à combler l'absence de toute étude sur la survie de la gigantomachie à travers les âges et à préciser l'emploi qui en serait fait à la Renaissance. Divers recueils d'ouvrages consacrés à la mythologie et remontant à cette période nous ont permis de décrire les modalités de la reprise du récit de la guerre des géants; en l'absence de toute synthèse sur ceux-ci dans la peinture de la Renaissance, c'est en partant de l'examen des nombreux travaux consacrés au Palazzo del Te à Mantoue que nous avons pu établir un lien entre les représentations de géants peintes durant la première moitié du 16ème siècle, au cours duquel la gigantomachie était redevenue un sujet d'actualité. Le monument de la bourgade lémanique comporte encore neuf personnages et constitue, avec celui d'Yzeures-sur-Creuse, l'exemplaire le plus complet découvert dans la partie occidentale de l'Empire romain : il méritait bien d'être à l'origine d'une telle démarche.

Treball de recerca realitzat per un alumne d'ensenyament secundari i guardonat amb un Premi CIRIT per fomentar l'esperit científic del Jovent l'any 2009. El treball tracta sobre la petita memòria històrica en la faceta de l'oci de la nostra societat , el ball i la música concretament, centrat en la memòria de l'avi de l'autor, músic, arranjador i compositor. Es tracta doncs, d'una investigació sobre la música de ball a Barcelona i a Catalunya, i en general també a Europa, atès que gràcies a les vivències d'en Vicenç Sabater (l'avi), es relata com era la seva feina i el seu ofici, el de músic. La recerca està ordenada cronològicament, començant pel seu naixement (1930), la formació i les primeres actuacions, passant per tota la seva vida personal, però sobretot professional, i conclou amb un epíleg sense el qual el treball de recerca no tindria sentit, ja que aquest explica com el Vicenç no s'ha jubilat mai, perquè sempre ha estat treballant amb la música, i perquè sempre que el seu físic li permeti, ell s'hi seguirà dedicant. El treball inclou un apartat destacat de la llarga etapa (30 anys) de Sabater amb el grup musical 'Rudy Ventura y su conjunto'. Molta d'aquesta informació s'obté a través d'entrevistes a dos dels cinc integrants del grup: el mateix Jaume Ventura, i en Joan Antoni Calvet, cantant i bateria, respectivament. Apartat que, dissortadament, s'ha convertit en el meu involuntari i modest homenatge a Jaume ('Rudy') Ventura , recentment traspassat.

Objectives and Methods: Self-report studies have shown an association between music performance anxiety (MPA) and hyperventilation complaints. However, hyperventilation was never assessed physiologically in MPA. This study investigated the self-reported affective experience, self-reported physiological symptoms, and cardiorespiratory variables including partial pressure of end-tidal CO(2) (Petco(2)), which is an indicator for hyperventilation, in 67 music students before a private and a public performance. The response coherence between these response domains was also investigated.ResultsFrom the private to the public session, the intensity of all self-report variables increased (all p values < .001). As predicted, the higher the musician's usual MPA level, the larger were these increases (p values < .10). With the exception of Petco(2), the main cardiorespiratory variables also increased from the private to the public session (p values < .05). These increases were not modulated by the usual MPA level (p values > .10). Petco(2) showed a unique response pattern reflected by an MPA-by-session interaction (p < .01): it increased from the private to the public session for musicians with low MPA levels and decreased for musicians with high MPA levels. Self-reported physiological symptoms were related to the self-reported affective experience (p values < .05) rather than to physiological measures (p values > .17).ConclusionsThese findings show for the first time how respiration is stimulated before a public performance in music students with different MPA levels. The hypothesis of a hyperventilation tendency in high-performance-anxious musicians is supported. The response coherence between physiological symptoms and physiological activation is weak.

Projecte de recerca elaborat a partir d’una estada a la National University of Singapore Singapur, entre juliol i octubre del 2007. Donada l'explosió de la música a l'internet i la ràpida expansió de les col•leccions de música digital, un repte clau en l'àrea de la informació musical és el desenvolupament de sistemes de processament musical eficients i confiables. L'objectiu de la investigació proposada ha estat treballar en diferents aspectes de l'extracció, modelatge i processat del contingut musical. En particular, s’ha treballat en l'extracció, l'anàlisi i la manipulació de descriptors d'àudio de baix nivell, el modelatge de processos musicals, l'estudi i desenvolupament de tècniques d'aprenentatge automàtic per a processar àudio, i la identificació i extracció d'atributs musicals d'alt nivell. S’han revisat i millorat alguns components d'anàlisis d'àudio i revisat components per a l'extracció de descriptors inter-nota i intra-nota en enregistraments monofónics d'àudio. S’ha aplicat treball previ en Tempo a la formalització de diferents tasques musicals. Finalment, s’ha investigat el processat d'alt nivell de música basandonos en el seu contingut. Com exemple d'això, s’ha investigat com músics professionals expressen i comuniquen la seva interpretació del contingut musical i emocional de peces musicals, i hem usat aquesta informació per a identificar automàticament intèrprets. S’han estudiat les desviacions en paràmetres com to, temps, amplitud i timbre a nivell inter-nota i intra-nota.

AbstractPerforming publicly has become increasingly important in a variety of professions. This condition is associated with performance anxiety in almost all performers. Whereas some performers successfully cope with this anxiety, for others it represents a major problem and even threatens their career. Musicians and especially music students were shown to be particularly affected by performance anxiety.Therefore, the goal of this PhD thesis was to gain a better understanding of performance anxiety in university music students. More precisely, the first part of this thesis aimed at increasing knowledge on the occurrence, the experience, and the management of performance anxiety (Article 1). The second part aimed at investigating the hypothesis that there is an underlying hyperventilation problem in musicians with a high level of anxiety before a performance. This hypothesis was addressed in two ways: firstly, by investigating the association between the negative affective dimension of music performance anxiety (MPA) and self-perceived physiological symptoms that are known to co-occur with hyperventilation (Article 2) and secondly, by analyzing this association on the physiological level before a private (audience-free) and a public performance (Article 3). Article 4 places some key variables of Article 3 in a larger context by jointly analyzing the phases before, during, and after performing.The main results of the self-report data show (a) that stage fright is experienced as a problem by one-third of the surveyed students, (b) that the students express a considerable need for more help to better cope with it, and (c) that there is a positive association between negative feelings of MPA and the self-reported hyperventilation complaints before performing. This latter finding was confirmed on the physiological level in a tendency of particularly high performance-anxious musicians to hyperventilate. Furthermore, the psycho-physiological activation increased from a private to a public performance, and was higher during the performances than before or after them. The physiological activation was mainly independent of the MPA score. Finally, there was a low response coherence between the actual physiological activation and the self-reports on the instantaneous anxiety, tension, and perceived physiological activation.Given the high proportion of music students who consider stage fright as a problem and given the need for more help to better cope with it, a better understanding of this phenomenon and its inclusion in the educational process is fundamental to prevent future occupational problems. On the physiological level, breathing exercises might be a good means to decrease - but also to increase - the arousal associated with a public performance in order to meet an optimal level of arousal needed for a good performance.

The spontaneous activity of the brain shows different features at different scales. On one hand, neuroimaging studies show that long-range correlations are highly structured in spatiotemporal patterns, known as resting-state networks, on the other hand, neurophysiological reports show that short-range correlations between neighboring neurons are low, despite a large amount of shared presynaptic inputs. Different dynamical mechanisms of local decorrelation have been proposed, among which is feedback inhibition. Here, we investigated the effect of locally regulating the feedback inhibition on the global dynamics of a large-scale brain model, in which the long-range connections are given by diffusion imaging data of human subjects. We used simulations and analytical methods to show that locally constraining the feedback inhibition to compensate for the excess of long-range excitatory connectivity, to preserve the asynchronous state, crucially changes the characteristics of the emergent resting and evoked activity. First, it significantly improves the model's prediction of the empirical human functional connectivity. Second, relaxing this constraint leads to an unrealistic network evoked activity, with systematic coactivation of cortical areas which are components of the default-mode network, whereas regulation of feedback inhibition prevents this. Finally, information theoretic analysis shows that regulation of the local feedback inhibition increases both the entropy and the Fisher information of the network evoked responses. Hence, it enhances the information capacity and the discrimination accuracy of the global network. In conclusion, the local excitation-inhibition ratio impacts the structure of the spontaneous activity and the information transmission at the large-scale brain level.

Cystic echinococcosis (CE) is a high prevalent zoonosis in the central and southern Peruvian Andes. Serum samples (n50)frompatients presenting presumptive clinical and radiological diagnosis of CE (group 1), were tested for antibodies against Echinococcus granulosus metacestode using Arc-5 double diffusion assay (DD5), immunoelectrophoresis (IEF), and immunoelectrotransfer blot (EITB) techniques. Serum samples (n18) from patients presenting other parasite infections (paragonomiasis, cysticercosis, and fascioliasis) or healthy blood donors (n15), were designated as control groups. The overall sensitivity of the tests was of 94% (DD5 and IEF tests) or 96% (EITB test). Only patients from group 1 were seropositive for CE. Polypeptides of 21, 31, and 48 kDa were considered positive for CE. Based on these results, this study demonstrates that CE also occurs in other coastal departments (Piura, Ancash, Ica, Arequipa, and Tacna) besides Lima.

Introduction Music performance anxiety (MPA, often referred to as "stage fright") is one of the leading severe medical problems among musicians. For about 15-25% of musicians MPA is a serious problem. Particularly high levels of MPA are observed among music students. Musical performance can induce negative emotions, including anxiety, which in some individuals can approach extreme levels of terror and take the form of panic attack, impair the quality of the performance, lead to avoidance of performance situations, and consequently have debilitating effects on the career. Coping efforts used by musicians in their attempts to manage MPA, such as sedatives, alcohol, and β-blockers can have deleterious health side-effects. Music ranks high in the cultural and economic life of Switzerland. In ten university music schools, students from all around the world are educated to become professional musicians. Despite the importance of musical education in Switzerland, data concerning the phenomenon of MPA are largely lacking. Goal and Methods The main goal of this research was to survey the occurrence, experience, and management of MPA among full-time music students in French Swiss conservatories. A questionnaire was developed based on the literature and interviews with music students and teachers and distributed to all the students of the conservatories of Fribourg, Geneva, Lausanne, and Neuchâtel in the spring 2007. 194 students (61% women) returned the questionnaire. Results The size of the problem: MPA is a major problem for 1/3 of the students (ranks 3 and 4). The consequences of MPA: 22% and 35% of the students think that they have failed exams and auditions, respectively, because of MPA. Further, 25% of the students have already avoided performing and 11% have interrupted public performances because of MPA. Coping with MPA: 90% of the students have never used alcohol prior to performing, whereas 97% and 81%, respectively, have never used recreation drugs and medication. The majority of students use relaxation exercises, respiratory exercises, and meditation techniques to prepare themselves. About ¾ of the students think that the use of alcohol and recreational drugs to manage MPA is never justified. 53% of the students think that the use of medication is justified on some occasions. Need for information and support: 66% of the students would like to receive more support and help to cope with music performance situations. This support should mainly come from their teachers and specialists. 53% of the students know nothing or little about possible means for the management of MPA. About 50% consider themselves not at all or little informed about the possible risks associated with the consumption of alcohol, recreational drugs, and medication for the management of performance situations. 89% would like to know more about MPA and 94% think that this topic should be discussed much more in their musical education at the conservatory. Conclusions The results of this survey indicate that MPA is a major problem for 1/3 of the students with serious consequences on their career. There is a huge need for more information and support on how to manage the stress due to performance situations. The use of alcohol, recreational drugs, and medication is modest but the students are poorly informed about possible side-effects of these coping strategies. It seems clear that more should be done in the French Swiss conservatories about music performance anxiety to inform, educate, and prepare the students for their future professional career.

The present study was conducted to explore whether single nucleotide polymorphisms (SNPs) in Th1 and Th17 cell-mediated immune response genes differentially influence the risk of rheumatoid arthritis (RA) in women and men. In phase one, 27 functional/tagging polymorphisms in C-type lectins and MCP-1/CCR2 axis were genotyped in 458 RA patients and 512 controls. Carriers of Dectin-2 rs4264222T allele had an increased risk of RA (OR = 1.47, 95%CI 1.10-1.96) whereas patients harboring the DC-SIGN rs4804803G, MCP-1 rs1024611G, MCP-1 rs13900T and MCP-1 rs4586C alleles had a decreased risk of developing the disease (OR = 0.66, 95%CI 0.49-0.88; OR = 0.66, 95%CI 0.50-0.89; OR = 0.73, 95%CI 0.55-0.97 and OR = 0.68, 95%CI 0.51-0.91). Interestingly, significant gender-specific differences were observed for Dectin-2 rs4264222 and Dectin-2 rs7134303: women carrying the Dectin-2 rs4264222T and Dectin-2 rs7134303G alleles had an increased risk of RA (OR = 1.93, 95%CI 1.34-2.79 and OR = 1.90, 95%CI 1.29-2.80). Also five other SNPs showed significant associations only with one gender: women carrying the MCP-1 rs1024611G, MCP-1 rs13900T and MCP-1 rs4586C alleles had a decreased risk of RA (OR = 0.61, 95%CI 0.43-0.87; OR = 0.67, 95%CI 0.47-0.95 and OR = 0.60, 95%CI 0.42-0.86). In men, carriers of the DC-SIGN rs2287886A allele had an increased risk of RA (OR = 1.70, 95%CI 1.03-2.78), whereas carriers of the DC-SIGN rs4804803G had a decreased risk of developing the disease (OR = 0.53, 95%CI 0.32-0.89). In phase 2, we genotyped these SNPs in 754 RA patients and 519 controls, leading to consistent gender-specific associations for Dectin-2 rs4264222, MCP-1 rs1024611, MCP-1 rs13900 and DC-SIGN rs4804803 polymorphisms in the pooled sample (OR = 1.38, 95%CI 1.08-1.77; OR = 0.74, 95%CI 0.58-0.94; OR = 0.76, 95%CI 0.59-0.97 and OR = 0.56, 95%CI 0.34-0.93). SNP-SNP interaction analysis of significant SNPs also showed a significant two-locus interaction model in women that was not seen in men. This model consisted of Dectin-2 rs4264222 and Dectin-2 rs7134303 SNPs and suggested a synergistic effect between the variants. These findings suggest that Dectin-2, MCP-1 and DC-SIGN polymorphisms may, at least in part, account for gender-associated differences in susceptibility to RA.

For the first time, we used multilocus sequence typing (MLST) to understand how Romanian group B streptococcus (GBS) strains fit into the global GBS population structure. Colonising isolates recovered from adult human females were tested for antibiotic resistance, were molecularly serotyped based on the capsular polysaccharide synthesis (cps) gene cluster and further characterised using a set of molecular markers (surface protein genes, pilus-encoded islands and mobile genetic elements inserted in the scpB-lmb intergenic region). Pulsed-field gel electrophoresis was used to complement the MLST clonal distribution pattern of selected strains. Among the 55 strains assigned to six cps types (Ia, Ib, II-V), 18 sequence types (STs) were identified by MLST. Five STs represented new entries to the MLST database. The prevalent STs were ST-1, ST-17, ST-19 and ST-28. Twenty molecular marker profiles were identified. The most common profiles (rib+GBSi1+PI-1, rib+GBSi1+PI-1, PI-2b and alp2/3+PI-1, PI-2a) were associated with the cps III/ST-17 and cps V/ST-1 strains. A cluster of fluoroquinolone-resistant strains was detected among the cps V/ST-19 members; these strains shared alp1 and IS1548 and carried PI-1, PI-2a or both. Our results support the usefulness of implementing an integrated genotyping system at the reference laboratory level to obtain the reliable data required to make comparisons between countries.

Using optimized voxel-based morphometry, we performed grey matter density analyses on 59 age-, sex- and intelligence-matched young adults with three distinct, progressive levels of musical training intensity or expertise. Structural brain adaptations in musicians have been repeatedly demonstrated in areas involved in auditory perception and motor skills. However, musical activities are not confined to auditory perception and motor performance, but are entangled with higher-order cognitive processes. In consequence, neuronal systems involved in such higher-order processing may also be shaped by experience-driven plasticity. We modelled expertise as a three-level regressor to study possible linear relationships of expertise with grey matter density. The key finding of this study resides in a functional dissimilarity between areas exhibiting increase versus decrease of grey matter as a function of musical expertise. Grey matter density increased with expertise in areas known for their involvement in higher-order cognitive processing: right fusiform gyrus (visual pattern recognition), right mid orbital gyrus (tonal sensitivity), left inferior frontal gyrus (syntactic processing, executive function, working memory), left intraparietal sulcus (visuo-motor coordination) and bilateral posterior cerebellar Crus II (executive function, working memory) and in auditory processing: left Heschl's gyrus. Conversely, grey matter density decreased with expertise in bilateral perirolandic and striatal areas that are related to sensorimotor function, possibly reflecting high automation of motor skills. Moreover, a multiple regression analysis evidenced that grey matter density in the right mid orbital area and the inferior frontal gyrus predicted accuracy in detecting fine-grained incongruities in tonal music.
