No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Filosofia e Ciências Humanas. Programa de Pós-Graduação em Antropologia Social.Esta é uma etnografia do universo do rock alterna tivo e das bandas independentes de Florianópolis (SC). Tem como foco as concepções musicais e discursos sobre música. Analiso o trabalho de 14 bandas, observando como estas se apropriam do rock e constituem estilos particulares a partir de um gênero de circulação global. Também analiso as relações destas bandas com a indústria fonográfica e o papel da tecnologia como constituinte do fazer musical. Trato o rock como um gênero musical vinculado a um conceito de arte e a uma estética específicos, ligados a um universo hedonista. O compartilhamento desta estética, assim como de uma ética, leva à configuração do que chamo de comunidade rock

Rock dos anos 1980, prefixo 48: um crime perfeito?
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Filosofia e Ciências Humanas. Programa de Pós-Graduação em História.A presente dissertação tem como objetivo principal a análise sobre a formação de grupos de rock, no que chamo Mundo 48, durante a década de 1980, suas músicas e como estas ajudavam a criarem suas redes sociais. O termo Mundo 48 caracteriza um espaçogeográfico através do prefixo telefônico, abordando a grande Florianópolis e parte da região sul catarinense. Sendo as bandas catarinenses um tema inédito, recorri inicialmente em uma discussão historiográfica sobre algumas das bandas estudadas. Tendo como recorte temporal principal, a atuação da banda Expresso Rural (posteriormente apenas Expresso), entre 1982 e 1992, neste período são criadas novas comunidades emocionais e características próprias na composição de canções e apresentação em shows e televisão. Porém, a Expresso Rural não é vista como principal. Outras bandas são analisadas com a mesma importância como a Ratones/Tubarão, Decalco Mania, Burn, Bandalheia ou Stryx, apenas para citar algumas. This present dissertation has as its main objective the analysis about the formation of rock groups, what I call Mundo 48, during the 80#s, their music and the way it would help them to create their social connections. The term Mundo 48 refers to a geographic space between an area code that goes from the whole Florianópolis down to part of the south Santa Catarina State. Being the Santa Catarina#s band a subject never studied before, I firstly appealed in a historiographical discussion about some of the bands. Based on the action of the band Expresso Rural (lately Expresso), between the years of 1982 and 1992, new emotional communities are created and particular characteristics are developed on the way songs are created and shows and T.V. programs are presented. However, the band Expresso Rural is not seen as the main band of that time. Some other bands are classified with the same importance, such as Ratones/Tubarão, Decalco Mania, Burn, Bandalheia or Stryx, naming a few
Harmony and discord within the English ‘counter-culture’, 1965-1975, with particular reference to the ‘rock operas’ Hair, Godspell, Tommy and Jesus Christ Superstar
No full textPhDThis thesis considers the discrete, historically-specific theatrical and musical sub-genre of ‘Rock Opera’ as a lens through which to examine the cultural, political and social changes that are widely assumed to have characterised ‘The Sixties’ in Britain. The musical and dramatic texts, creation and production of Hair (1967), Tommy (1969), Godspell (1971), Jesus Christ Superstar (1970) and other neglected ‘Rock Operas’ of the period are analysed. Their great popularity with ‘mainstream’ audiences is considered and contrasted with the overwhelmingly negative and often internally contradictory reaction towards them from the English ‘counter-culture’. This examination offers new insights into both the ‘counter-culture’ and the ‘mainstream’ against which it claimed to define and differentiate itself.
The four ‘Rock Operas’, two of which are based upon Christian scriptures, are considered as narratives of spiritual quest. The relationship between the often controversial quests for re-defined forms of faith and the apparently precipitous ‘secularization’ and ‘de-Christianization’ of British society during the 1960s and 1970s is considered.
The thesis therefore analyses the ‘Rock Operas’ as significant, enlightening prisms through which to view many of the profound societal debates – over ‘faith’ and ‘belief’ in the widest senses, sexuality, the Vietnam war, generational conflict, drugs and ‘spiritual enlightenment’, and race – which were, to some considerable extent, elevated onto the national, political agenda by the activities of the broadly-defined ‘counter-culture’. It considers subsequent representations of the ‘counter-culture’ as the root of a contested but enduring popular legacy of ‘The Sixties' as a period of profound cultural change

Uma trajetória singular pelo rock gaúcho: os sentidos do trabalho acústico para um músico profissional
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Filosofia e Ciências Humanas. Programa de Pós-Graduação em Psicologia.Esta dissertação teve como objetivo a compreensão do sentido do trabalho para um músico profissional. Com base nas contribuições da Psicologia Histórico-Cultural de Lev Vygotskyi e dos postulados ontológicos de Jean-Paul Sartre, compreendemos o sujeito como constituinte de um contexto sócio-histórico. Este sujeito, social desde o seu nascimento, é subjetividade, que está em constante relação com a objetividade do contexto, sendo este constituído de signos culturais. Enfocamos a profissão de músico como categoria de estudo, correlacionando com as categorias trabalho e emprego, partindo de uma análise histórica, enfatizando as transformações sociais, econômicas, tecnológicas e culturais de uma sociedade capitalista. Devido ao fato do sujeito da pesquisa ser um roqueiro, dedicamos parte da análise à emergência do rock no Brasil e no mundo, compreendendo o rock como um gênero musical. O método utilizado no estudo foi o progressivo-regressivo, oriundo dos postulados de Sartre, que compreende a relação do sujeito, constituinte de uma singularidade, com o mundo objetivo, buscando utilizar as contribuições da análise de discurso, principalmente, a partir da perspectiva de Mikhail Bakhtin. Na objetivação da história deste sujeito, podemos observar que o diálogo entre a singularidade e a universidade se faz expressão e fundamento de Fughetti como sujeito histórico. Por meio da (re) construção de sua história e de seu discurso, podemos compreender como a música e o trabalho acústico constituíram e continuam constituindo o movimento de subjetivação e objetivação de Fughetti, caracterizando o sentido do trabalho musical, na composição e na atividade sonora, como similar a própria vida
The formation of valley-wall rock glaciers
No full textIn recent years, the study of rock glaciers has increased remarkably. Substantive
progress has been made, particularly in understanding the formation of rock
glaciers that have developed adjacent to existing or former valley or cirque
glaciers, However, our understanding of valley-wall rock glaciers that are
located at the base of talus slopes remains scant. Published work exhibits little
consensus on the formation of valley-wall rock glaciers and several hypotheses
remain under vigorous debate. The major objective of the research reported in
this thesis has been to test the generality and feasibility of seven major models
of valley-wall rock glacier formation using both empirical and theoretical
evidence. The primary conclusion is that only one of these models, the
segregation ice model, emerges as a general model of valley-wall rock glacier
genesis. The model assumes that a thin layer or several thin layers of
segregated ice are overlain by interstitially frozen sediments and an unfrozen
mantle of coarse debris. A wide range of empirical and theoretical findings are
shown to be consistent with the implications of the segregation ice model.
Detailed observations on the morphology, sedimentology and distribution of
active, inactive and relict valley-wall rock glaciers studied in Switzerland,
northern Norway and Scotland provided a range of findings that support this
model. Theoretical evidence was obtained by modelling a number of different
density models that reflect different distribution of internal ice by applying a
simple laminar flow equation to field measurements. Although only the
segregation ice model appears to be valid at a general level, the possibility
cannot be excluded of alternative modes of valley-wall rock glacier formation
under particular circumstances. Snow avalanching, deformation of snowbank
or matrix ice, and basal sliding under conditions of high hydrostatic pressure all
constitute possible contributing mechanisms of formation and movement in
particular cases
Modelling rock slope behaviour and evolution with reference to Northern Spain and Southern Jordan
No full textThe geomorphological behaviour of steep jointed rock slopes has been studied using distinct element computer models. In order to model steep slopes effectively, methodologies need to be combined from the studies of environmental modellers, geomorphologists and engineers. The distinct element method is ideal for the study of the development of jointed rock masses, where the failure is controlled by the nature of the discontinuities. Theoretical modelling identified that block size is a key control affecting the deformation of rock masses. Deformation of rock masses with smaller block assemblages is greater than for rock masses composed of larger block sizes. This is due to the increased magnitude of joint normal closure. Catastrophic failure is less likely in slopes with smaller block sizes because the shear strength is greater in a closely jointed rock mass. These slopes are more likely to undergo gradual deformations. Block-size effects are also responsible for influencing the failure mechanism of rock masses. As block size decreases, the magnitude of block rotation increases and the failure mechanism changes from sliding to toppling. The effect of slope scale on the deformation properties of the rock masses has also been investigated. Two field locations, the Picos de Europa mountains, northern Spain and Wadi Rum, southern Jordan, have been chosen to provide a link between the theoretical modelling and classic rock landforms which are controlled by the discontinuity geometry. Given the sporadic and infrequent occurrence of failure events at the field sites, a computer modelling approach has been adopted to analyse slope behaviour. In the Picos de Europa, slope deformations are deep-seated, with sliding and toppling being the dominant modes of failure. Much of the slope deformation in these mountains is a result of post-glacial rock-slope deformation. The sandstone inselbergs of Jordan show a range of morphologies from rounded hills to vertical cliffs. The morphology of the inselbergs is related to the intact rock strength; stronger Red lshrin sandstone forms vertical slopes, whereas the weaker Disi sandstone forms rounded domes. Jointing in the area is sub-vertical with horizontal bedding and computer simulations have shown that toppling is the dominant mode of failure in these inselbergs. Comparison of computer model output suggests that different failure mechanisms have distinct failure signatures. Catastrophic, deep-seated failures are characterised by a long period of acceleration as the failure propagates through the rock mass and infinite velocity is reached. Non-catastrophic slope movements, such as self-stabilising topples, are characterised by short periods of acceleration followed by small creep movements at a constant velocity. Computer modelling has indicated that scale effects do exist in the modelled rock masses from the Picos de Europa and particularly Wadi Rum. In areas where jointing is constant, the relative block size of the rock mass decreases as slope scale increases. The greater numbers of blocks along with greater in situ stresses influence the failure of the slope. Cosmogenic dating was used to temporally constrain UDEC model output and provide a better understanding of rock slope failure mechanisms in the Picos de Europa and Wadi Rum. Dating indicated delayed paraglacial adjustment was the triggering mechanism for slope failure in the Picos de Europa, whereas failures in Wadi Rum appeared to be closely linked with wetter climatic conditions
Predynastic & Pharaonic era Rock-Art in Egypt’s Central Eastern Desert: Distribution, Dating & Interpretation
No full textThe aim of this thesis is to examine the rock-art of Egypt’s Central Eastern Desert in order to outline the petroglyphs’ distribution and influences on their location, to date them, and to explore the reasons why they were created. The area is notable for the presence of boat petroglyphs, along with images of people and a wide range of fauna, in the middle of the desert many miles from the Nile and Red Sea. Since Hans Winkler’s pioneering work in the 1930’s, the corpus covering the whole of the area has been considerably increased due to work from the 1980’s to the present, thanks mainly to the Eastern Desert Survey (EDS) and the Rock Art Topographical Survey (RATS).
The construction of a comprehensive corpus enables an analysis of the distribution of the approximately 4000 images, the dating of a significant majority of the rock-art sites and interpretation of the reasons for their creation. Many of the petroglyphs were probably made in the early predynastic period: Naqada I c to II a/b (which scholars generally date from 3750 to 3650 BCE), and often show hunting scenes associated with boats, or even have vessels integrated within them. As the spatial analysis carried out in this work demonstrates, these motifs are often located in shaded locations and, especially in the south of the survey area, near to the entrances to side wadis. In contrast, the smaller numbers of dynastic and Greco-Roman images are usually situated on routes to the mines and quarries of the Eastern Desert, as well as to the Red Sea.
This thesis also proposes a new approach to the interpretation of boats and the figures with arms raised and incurved above the head. As opposed to common scholarly practice where they have previously been interpreted by retrospective comparison with pharaonic themes, I pursue a synchronic approach to interpretation, placing the predynastic motifs in Naqada culture funerary context linked to hunting as an elite activity. The later rock-art is divided between pharaonic images related to mining and quarrying expeditions, and horse and camel riders pictured in unique conflict scenes
Phylogeny of rock-inhabiting fungi related to Dothideomycetes
No full textThe class Dothideomycetes (along with Eurotiomycetes) includes numerous rock-inhabiting fungi (RIF), a group of ascomycetes that tolerates surprisingly well harsh conditions prevailing on rock surfaces. Despite their convergent morphology and physiology, RIF are phylogenetically highly diverse in Dothideomycetes. However, the positions of main groups of RIF in this class remain unclear due to the lack of a strong phylogenetic framework. Moreover, connections between rock-dwelling habit and other lifestyles found in Dothideomycetes such as plant pathogens, saprobes and lichen-forming fungi are still unexplored. Based on multigene phylogenetic analyses, we report that RIF belong to Capnodiales (particularly to the family Teratosphaeriaceae s.l.), Dothideales, Pleosporales, and Myriangiales, as well as some uncharacterised groups with affinities to Dothideomycetes. Moreover, one lineage consisting exclusively of RIF proved to be closely related to Arthoniomycetes, the sister class of Dothideomycetes. The broad phylogenetic amplitude of RIF in Dothideomycetes suggests that total species richness in this class remains underestimated. Composition of some RIF-rich lineages suggests that rock surfaces are reservoirs for plant-associated fungi or saprobes, although other data also agree with rocks as a primary substrate for ancient fungal lineages. According to the current sampling, long distance dispersal seems to be common for RIF. Dothideomycetes lineages comprising lichens also include RIF, suggesting a possible link between rock-dwelling habit and lichenisatio
