Para uma história das sensibilidades e das percepções: vida e obra em Valda Costa
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Filosofia e Ciências Humanas. Programa de Pós-Graduação em História.O objeto desta tese é abordar a vida e a obra de Valda Costa (1951-1993), uma artista florianopolitana afrodescendente de origem pobre e pouco estudo criada no Morro do Mocotó, localidade de baixa renda situada próxima ao centro de Florianópolis. Morreu pobre e esquecida, após fulgurante ascensão como artista plástica: desde meados dos anos 1970, entrando pelos anos 1980, freqüentou os mais concorridos ambientes culturais locais na condição de pintora que lograra alcançar uma considerável aceitação no mercado florianopolitano de artes plásticas. A pesquisa explora os nexos entre vida e obra da artista, encarando a segunda como uma narrativa biográfica em forma de retratos. O estudo realizado não só leva em conta os contextos político-cultural e socioeconômico que envolveram a materialização dessa produção artística, mas igualmente estabelece relações com a produção de outros artistas, em outros períodos e lugares, relações essas inspiradas no pensamento do teórico alemão Aby Warburg. As contribuições desse autor, pertencentes aos campos da História Cultural e da Teoria da Imagem, estão na origem da matriz conceitual empregada na tese. Seu uso neste estudo baseia-se na convicção de que a fertilização cruzada de disciplinas - História e Teoria da Imagem - possibilita novos e promissores olhares sobre histórias de sensibilidades e de percepções

Catedral Metropolitana de Florianópolis: retrospectiva histórica das intervenções arquitetônicas
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Tecnológico. Programa de Pós-Graduação em Arquitetura e UrbanismoA Catedral Metropolitana de Florianópolis é o marco zero na fundação da Villa de Nossa Senhora do Desterro no século XVI. Exemplar arquitetônico que muito contribui no testemunho da historicidade catarinense, não só com seus valores arquitetônicos e acervo sacro, mas também quanto a seu patrimônio imaterial constituído durante seus quase trezentos anos de existência. É um ícone que se mantém como fio condutor da transmissão dos signos e símbolos da Florianópolis de outrora. Este trabalho busca identificar as alterações arquitetônicas que aconteceram ao longo do tempo na edificação, por meio da reconstituição histórica destas intervenções, organizando os fatos relacionados às intervenções de forma cronológica. A coleta de dados nos Livros Tombo trouxe a público, fatos inéditos sobre as fases de intervenções na Catedral com suas respectivas datações. As entrevistas e as pesquisas documentais contribuem no esclarecimento de relatos e informações sobre os procedimentos adotados, além de citar materiais construtivos utilizados e suas aplicações; foram encontrados relatórios, contratos, propostas e justificativa de intervenções. O resultado deste trabalho consiste na organização, em seqüência cronológica, das alterações arquitetônicas, dividindo-as em etapas, apresenta-se de forma gráfica e textos, relacionadas às circunstâncias temporais

Interpolated Lake Bathymetry of Lake Lucerne
No full textThis dataset provides the interpolated bathymetry of Lake Lucerne used for the numerical wave propagation simulation performed in the study “Shallow-Water Tsunami Deposits: Evidence from Sediment Cores and Numerical Wave Propagation of the 1601 CE Lake Lucerne” by Nigg et al. (in review). The multibeam echo-sounder bathymetry dataset of Lake Lucerne acquired by Hibe et al. (2011) was resampled from a grid size of 1x1 m to 5x5 m to reduce computational time using ArcMap (version 10.8.1). In addition, large artificial shoreline modifications were cropped and interpolated based on historical maps. Shallow-water areas (water depth 0-4m), which are not entirely covered by the bathymetrical data were linearly interpolated to the shoreline.
The original bathymetry was acquired using a Geo-Acoustics GeoSwath Plus 125 kHz interferometer by Hilbe et al. (2011). Positioning was acquired with a Leica SR 530 GPS receiver with real time kinematic positioning (RTK; swipos GIS/GEO from swisstopo). Acquisition control and data processing were conducted using the GeoAcoustics GS+ software package. Swiss basic hydrological monitoring network (BAFU, 2008) were used to normalize water depths to the mean lake level (433.6 m a.s.l.). See Hilbe et al. (2011) for further information. The original bathymetry dataset is available from swisstopo and should be referenced as Hilbe, M., Anselmetti, F. S., Eilertsen, R. S., Hansen, L., & Wildi, W. (2011).

Modern remote sensing for environmental monitoring of landscape states and trajectories
No full textContemporary and emerging remote sensing technologies, combined with biophysical first principles and modern spatial statistics allow for novel landscapes analyses at a range of spatial and temporal scales. In the past, supervised or un-supervised classification methods and the development of indices of landscape degradation and other derived products based on multi-spectral imagery of various resolutions has become a standard. Biophysical indices, such as leaf area index, fraction of photosynthetically-active radiation, phytomass or canopy chemistry, can be derived from the spectral properties of satellite imagery. Indices of changes in landscape composition and structure can be measured from the thematic maps originating from remotely-sensed imagery. Additionally, 30-year or longer time series of historical remote sensing archives (Landsat, AVHRR) allow retrospective studies of the historical range of variability and the trajectories of both landscape elements and biophysical properties.
A trade-off exists between high spatial and high temporal resolution when comparing platforms. Development of new, improved sensors and analysis techniques, such as sub-pixel classifications resulting in the development of continuous fields for formerly discrete classes, has reduced this trade-off. High spectral resolution and multiple view angles even enhance the potential for accurate retrieval of variables such as Albedo and chlorophyll concentration. Thus, powerful monitoring tools for land use/cover change detection are arising from such analyses. They can lead to an improved understanding of landscape states and processes. Finally, this evolution allows for mapping and monitoring of new landscape features that were not much used to date
Role of climate and herbivory on native and alien conifer seedling recruitment at and above the Fennoscandian tree line
No full textQuestions: We investigated the importance of climate and herbivory on native and alien conifer colonization of the birch-dominated Fennoscandian tree line by addressing the following questions: (a) are tree line and tundra habitats similarly suitable for conifer seedling recruitment; (b) do ungulate and rodent herbivores differentially impact seedling recruitment; and (c) how does the role of habitat and herbivory on seedling recruitment vary across a marked climate gradient? Location: Northern Fennoscandia, Sweden (Vassijaure and Paddus), and Norway (Joatka and Seiland). Methods: We conducted an experiment to assess the emergence rate, survival probability and height development of Norway spruce (Picea abies), Scots pine (Pinus sylvestris) and Siberian larch (Larix sibirica) seedlings. Three experimental plots (i.e., open control, reindeer exclosure and complete vertebrate exclosure) were established in both tree line and tundra habitats at each of the four locations. Seeds of the three conifer species were sown in each plot in June 1999 during three consecutive years. The surviving seedlings were counted in August to September 1999, 2000, 2001, 2002 and 2007. The height of all seedlings was measured in 2007. Results: Our study reveals that Norway spruce, Scots pine and Siberian larch can regenerate from seed at and above the current tree line in northern Fennoscandia. Their performance was generally higher above tree line in tundra than at tree line, but depended on species identity, climate aridity and mammal herbivory, particularly by rodents. These results suggest that the species composition and latitudinal limit of the tree line in the future might depend not only on direct effects of the future climate on the current tree line species, but also on the intensity of alien and native conifer introductions, as well as changes in herbivore populations. Conclusion: If sufficient seeds of Norway spruce, Scots pine and Siberian larch should reach the current tree line, their performances will increase with a warmer and wetter climate, and this effect will be markedly modulated by herbivores (particularly rodents). Further work is required to extend these results to determine the ability of these conifers to become tree line-forming species in the future
AN ERROR ANALYSIS OF ARABIC WRITING BY ISLAMIC VOCATIONAL HIGH SCHOOL STUDENTS
No full textThis research examined different types of writing errors performed by Islamic Vocational High School students undertaking the Arabic course. The current study also discussed the plausible causes of errors committed by the students. A mixed-method approach was used to investigate and analyze a corpus of students’ writing. The data were collected through documentation and obtained from the essays of tenth and eleventh-grade students with 40 respondents. The study employed error analysis steps by Corder as a framework to deal with deviated grammatical rules, including collecting, identifying, classifying, quantifying data, and analyzing sources of errors. The results showed that the most dominant error was spelling, with 35.44%, followed by 28.16% errors in phrases, 22.81% in sentence structures, and 13.59% in agreement. Several possible causes of such errors include overgeneralization, ignorance of rule restrictions, incomplete application of rules, and false concepts hypothesized
