The polyphonic sources of medieval Sweden are very few, although well-documented in musicological research. However, while most of the earlier research has tended to focus on interpreting the sources themselves rather than to examine the cultural and historical context in which they were written, the present dissertation aims at providing a broader narrative of the transmission and practice of polyphony. By examining the cultural context of the sources and putting them in relation to each other, a bigger picture is painted, where also Danish and Norwegian sources are included. Based on the discussion and analyses of the sources, a general historical outline is suggested. The practice of organum in the late 13th century in Uppsala was probably a result from Swedes studying in Paris and via oral transmission brought the practice back home. This 'Parisian path' was accompanied by an 'English-Scandinavian' path, where mostly Denmark and Norway either influenced or were influenced by English polyphonic practice. During the 14th century, polyphony seems to have been rather established in Sweden, although prohibitions against it were made by the Order of the Bridgettines. These prohibitions were probably linked to a general antipolyphonic attitude in Europe, beginning with the papal bull of John XII in 1324. The sources of the 15th and 16th centuries are very different from each other, and perhaps suggest that polyphony of older styles were sung in monasteries and certain churches while more modern discant were sung at the royal courts and at larger religious feasts such as the translation of Catherine of Vadstena.

No. of bitstreams: 1 Carlos Jacinto Nascimento Motta.pdf: 1413752 bytes, checksum: 466d45d754b40761f382c04cc0cb65a4 (MD5) Previous issue date: 2015-10-23 / The PhD. thesis here offered has as its aim the presentation of the Baconian conception of induction, understood as an essential element for the realization of Francis Bacon s project of a Restauration of by means of a reform of learning and sciences. In his most important and influente work, the Instauratio Magna, Bacon highlights the need for a wide survey of both the knowledge and sciences already established in order to know which of these should be abandoned, which perfected and which still are in need of implementation. Once this is achieved, and with due governamental support, a new scientifical era was supposed to begin and many advancements would also be achieved by Humankind. Notwithstanding, as Bacon points out, the reformation of sciences demands a change in the proceedings used by the investigator, which, in turn, results in a reformulation of both the idea of experience and the pattern of inference. It also indicates that the new scientifical era demands the establishment of investigative communities instead of isolated researchers, so that common mistakes to human nature should be avoided. This change, however, could only be realized in a mind duly cleansed of prejudices caused by both the philosophical tradition and by the natural characteristics of Humankind. The first were supposed to be corrected by means of the purging of idols, i.e. false notions which inhabit our mind and are imposed by culture; the latter, being these the greatest impediments on account of having to do with human nature itself, would be corrected by means of three different modalities of help, which combined form the novum organum (the new induction) or the new pattern of Bacon s scientific inference. This new induction must be understood in the contexto of the need for reformulations which promote the necessary aid to the investigator, being the histories the aids to the senses, the tables of presentation of instances the aids to memory and the new induction (Novum Organum) the aid to reason. Thus, we understand that the best interpretative key as regards the Baconian epistemology is the proposal of a reform of human understanding, and not merely the reformation of the logic used in investigations. Such reform would possibilitate the emergence of a new man, gifted with new logical tools and which would cooperate with other researchers towards the aim of assembling a type of inferential device, a collective investigative machine / A tese de doutorado aqui apresentada tem por objetivo apresentar a concepção baconiana de indução entendida como elemento essencial para a efetivação do projeto de Francis Bacon de uma Restauração da humanidade por meio da reforma do conhecimento e das ciências. Em sua mais significativa e influente obra, a Instauratio Magna, Bacon estabelece a necessidade de uma ampla avaliação dos saberes e ciências já constituídos a fim de saber quais devem ser abandonados, quais aprimorados e quais ainda necessitam implantação. De posse desse inventário, e com o devido apoio governamental, uma nova era científica teria início e muitos avanços seriam alcançados pela humanidade. Contudo, observa Bacon, a reforma das ciências exige uma alteração dos procedimentos adotados pelo investigador, o que leva a uma reformulação da ideia de experiência e do padrão de inferência utilizados. Também indica que a nova era científica exige que sejam constituídas comunidades investigativas, em lugar dos pesquisadores, a fim de se evitarem os erros comuns à natureza humana. Mas, isso somente poderia ser efetivado em uma mente devidamente purificada dos prejuízos causados pela tradição filosófica e pelas características naturais do homem. Os primeiros seriam corrigidos por meio da eliminação dos Ídolos, as falsas noções que habitam nossa mente impostas pela cultura. As segundas, os maiores impedimentos por se tratarem da própria natureza humana, seriam corrigidos por meio de três diferentes modalidades de ajuda, que juntas formam o novum organum (ou nova indução), o novo padrão de inferência científica de Bacon. Esta nova indução deve ser entendida no contexto da necessidade de reformas que promovam os auxílios necessários ao investigador, sendo as histórias os auxílios aos sentidos, as tábuas de organização das instâncias os auxílios à memória e a nova indução (ou novum organum) o auxílio à razão. Assim, nosso entendimento é que a melhor chave interpretativa para a epistemologia baconiana é a proposta de uma reforma do entendimento humano, não meramente a reforma da lógica utilizada nas investigações, da qual emergiriam um outro homem, dotado de novas ferramentas lógicas, trabalhando em cooperação, formando uma espécie de dispositivo inferencial, ou uma máquina investigativa coletiva

Rhythm in early Western polyphonic music.

Discrete electrical stimulation of the organum vasculosum of the lamina terminalis (OVLT) produces sympathetically-mediated increases in peripheral resistance and arterial blood pressure (ABP). Since efferent fibers from the lamina terminalis innervate the kidney through polysynaptic connections, the present study determined whether electrical stimulation of the OVLT increased sympathetic outflow to the kidney. In anesthetized male, Sprague-Dawley rats (n=5) electrical stimulation of OVLT neurons produced frequency and current intensity dependent increases in renal sympathetic nerve activity (RSNA) and ABP that were abolished by ganglionic blockade with the nicotinic antagonist chlorisondamine (5mg/kg,i.v.). Since neurons from the OVLT terminate within the hypothalamic paraventricular nucleus (PVH), the present study also determined whether these connections mediate a portion of sympathetic and pressor responses to electrical stimulation of the OVLT. Bilateral inhibition of the PVH with the GABAA agonist muscimol (5mM/100nl) significantly attenuated the increase in ABP at all frequencies and current intensities. Spike-triggered averaging of RSNA revealed that PVH inhibition significantly blunted the RSNA responses to OVLT stimulation at 100, 200, but not 400andamp;igrave;A. The present findings indicate that electrical stimulation of the OVLT increases RSNA and ABP and that these responses are partially mediated by the tonic activity of PVH neurons.
