No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Tecnológico. Programa de Pós-Graduação em Engenharia Ambiental.Esta dissertação apresenta a construção de uma metodologia participativa na construção temática do Atlas Escolar Ambiental. Trata-se de um trabalho de pesquisa-ação realizado com um professor e um grupo de alunos da Escola de Educação Básica Silva Jardim no município de Alfredo Wagner. A prática interdisciplinar e a abordagem sistêmica foram utilizadas como referencial para o desenvolvimento da metodologia participativa. Os procedimentos utilizados foram as reuniões, os trabalhos de campo para coleta de informações e registro fotográfico, entrevistas e visitas aos órgãos públicos. A metodologia participativa, seja com os grupos participantes ou com demais colaboradores voluntários na pesquisa, mostrou-se adequada à elaboração temática do Atlas, imprimindo a este as observações e os significados dos atores que, ao mesmo tempo, possuem a vivência da realidade do município. Os participantes se sentiram valorizados por participarem no grupo, ter vez e voz, fazer críticas e sugestões. O interesse do grupo no trabalho, nas reuniões e trabalhos de campo se fez na construção da contextualização dos temas, apontando os aspectos positivos que visualizam no município e também as situações problemas que merecem ser abordadas. Os trabalhos de campo evidenciaram que após a experiência de (re)conhecer o município, o significado e a importância dos lugares para os participantes são reafirmados, ou seja, reforça a identidade das pessoas com o #lugar#. O Atlas procura sintetizar, de maneira singular, o resultado do processo participativo que se mostrou de maneira ampla nas expressões dos participantes. Desta maneira, pretende-se que a metodologia participativa cristalizada no processo participativo, reflita no recorte temático do Atlas, a realidade e a história do município. This dissertation presents the construction of a participative methodology in the thematic construction of Environmental School Atlas. It is about a work of research-action carried through with a teacher and a group of students from the #Escola de Educação Básica Silva Jardim# in the city of Alfredo Wagner. The interdisciplinary practice and the systemic approach had been used as a referential for the development of the participative methodology. The used procedures were meetings, the field works for the information collection and photographic register, interviews and visits to the public agencies. The participative methodology, either with the participant groups or with other collaborating volunteers in the research, revealed adequate to the thematic elaboration of the Atlas, indicating to this the observation and the meanings of the people who, at the same time, have the experience of the city reality. The participants felt valued of participating in the group, having place and voice, criticizing and making suggestions. The group interest in the work, the meetings and the field works had been made in the construction of the context of the subjects, pointing the positive aspects that visualize in the city and the problematic situations that deserve to be approached. The field works evidenced that after the experience of (re) knowing the city, the meaning and the importance of the places for the participants are reaffirmed, that is, strengthen the identity of the people with the #place#. The Atlas looks for to synthesize, in a singular way, the result of participative process that showed in an ample way in the participant expressions. In this way, it is intended that the crystallized participative methodology in the participative process, reflects in the Atlas thematic clipping, the city reality and history

On Automatic Prominence Detection for German
No full textTamburini F, Wagner P. On Automatic Prominence Detection for German. In: Proceedings of Interspeech 2007. 2007: 1809-1812.Perceptual prominence is an important indicator of a word's and syllable's lexical, syntactic,
semantic and pragmatic status in a discourse. Its automatic annotation would be a valuable
enrichment of large databases used in unit selection speech synthesis and speech recognition.
While much research has been carried out on the interaction between prominence and
acoustic factors, little progress has been made in its automatic annotation. Previous
approaches to German relied on linguistic features in prominence detection, but a purely
acoustic method would be advantageous. We applied an algorithm to German data that had
been previously used for English and Italian. Both the algorithm and the data annotation
encode prominence as a continuous rather than a categorical parameter. First results are
encouraging, but again show that prominence perception relies on linguistic expectancies as
well as acoustic patterns. Also, our results further strengthen the view that force accents are a
more reliable cue to prominence than pitch accents in German

Palaeozoic black shales: how much should we trust the Recent to reconstruct the Past?
No full textOrganic-carbon-rich sediments were widely deposited during multiple intervals of Mesozoic and Palaeozoic time or even earlier; on the contrary, sediments rich in organic carbon are today restricted to small areas along continental margins and have rarely accumulated during the Cenozoic. Global marine deposits document that episodes of accumulation of OC-rich sediments occurred in different regions and at different times.These episodes were linked to climatic and palaeoceanographic perturbations that resulted in massive fluctuations in hydrologic and nutrient cycles and in ocean chemistry and that recurred throughout geologic time.The whole Palaeozoic is punctuated by a profusion of episodes of black shale deposition that represent a common and not unusual sediment for that time. Furthermore, the abundance of organic matter does not, per se, imply black shales. The Palaeozoic, in fact, is also characterized by fossiliferous OC-rich limestones, e.g. the Silurian–Devonian “Orthoceras limestones” bordering northern Gondwana. However, the paucity of survivingPalaeozoic and earlier black shale sections makes it difficult to impossible to recognize the internal structure of global events that are common in younger OC-rich sedimentary sequences. Going ever deeper into the past, in fact, two factors appear playing a more and more fundamental role: preservation and time resolution. OC-rich sediments, either in form of black shales or limestones, do not necessarily reflect periods of elevateddeposition of high organic matter but may paradoxically simply represent times of better organic matter preservation. Then, even well-dated sequences do not offer the high resolutionrecords needed to fully document or delineate short-time processes. In the Palaeozoic the length of individual biozones is generally on the order of millions of years, which is in the same range as third-order sea-level changes. Thus, an important question in Palaeozoic sequences is whether episodes occur at different scales or belong to cycles of diverse order.Also according to this premise, too often was exasperate the use of the uniformitarianism principle in which models or opinions derived from recent examples are simplistically applied to any of the older “timeboxes”. In actuality, physical and biological conditions (e.g., oxygen and CO2) have strongly varied through time. Palaeozoic black shales were clearly deposited in a CO2-dominated setting (see Berner, 1994, 1998), whereas youngerdeposits reflect a lower concentration of the same gas. Again, the nature of primary producers is not yet completely defined for pre-Jurassic production of organic matter.Furthermore, palaeogeographic scenarios reveal completely different worlds in terms of land masses, oceans, palaeolatitudes, etc. According to this, any attempt to model the deposition of OC-rich sediments through the Phanerozoic must necessarily be tuned with all these variables. Another relevant point is that some of the Phanerozoic OC-rich sediments are defined as global events, like the Cretaceous OAE1a and OAE2, but some othersappear to have had a more restricted and even localized significance. These differences require the application of different approaches in search of possible interpretations and perhaps diverse mechanisms leading to the deposition of OC-rich sequences.Finally, many of the most significant black shale episodes in the Palaeozoic strictly match with major crises in the history of life. Understanding what drives global diversity may be used to explain processes, such as mass extinctions, that control diversity and turnover at a variety of geographic and temporal scales.The main issues described here need to be further investigated and are certainly worth answering. The Scientific Community must come to a multiple-time scale approach and to a constructive dialogue that better integrates data and models in order to be even more successful. These efforts, with an emphasis on the upscaling/downscaling of processes and effects/feedbacks, will lead to the identification of methodologies that may be used uniformly in the Palaeozoic, Mesozoic and Cenozoic. In that case the scientific community will be able to test the validity of processes in the recent as well as its application in the past, to obtain real progress in the knowledge of OC-rich sediments, and to gain credibility for delineating true perspectives for the future.REFERENCESBERNER R.A.

Wagnerisms : An overview about the European Wagner receptions with a focus on the North
No full textGiven that Wagner succeeded in establishing himself as a national icon, it is not surprising that he was seen abroad as a representative of German culture. However, all over Europe as composers and dramatists began imitating his style in the late nineteenth century, they adapted it to their own national traditions. In this respect Wagner’s work became synonymous with national art in music theatre in different contexts, modified according to particular national self-images. Moreover, Wagner reception in Europe differed from country to country in social terms. For instance, French wagnérisme was quite elitist. It was restricted to the upper social classes and to artists, whereas German Wagnerianer came from all different classes and professions. It is therefore no exaggeration to speak of various national Wagnerisms. In my essay I concentrate especially on Wagnerism in Sweden and Finland, where Wagnerism seems to have differed from the German and the French practices, as well as taking different forms in each of these two Nordic countries. Swedish and Finnish Wagnerisms will be evaluated against the backdrop of other European Wagner imitations. This overview will focus on the introduction of Wagner’s practical and theoretical work into composition, the operatic repertoire and the cultural life of the European North. </p
