Auto-avaliação dos Discentes do Curso de Ciências Biológicas da Unemat, Campus de Nova Xavantina: um modelo para avaliação das disciplinas curriculares, segundo a percepção do corpo discente e docente

This paper presents an evaluation of the curriculum subjects of the Biological Sciences course in the University of the State of Mato Grosso (UNEMAT), Nova Xavantina campus, Brazil. The research was carried out by means of a self-assessment instrument, aimed at searching learners' and educators' points of view. The questionnaires were given in the first, third and seventh semesters, in which students were asked to assess pedagogical aspects regarding professors and their didacticism, as well as the subject matters being taught; in addition, they were invited to evaluate themselves as learners. The data was analyzed using statistical parameters, in order to measure teaching performance, and, subsequently, professors were given the opportunity to express their concepts about the students' assessment. The average value of the overall Cronbach's alpha coefficient was 0.923±0.001, a significant value considering that alpha varies between 0 and 1, which proves the questionnaire to be reliable. The hierarchical cluster analysis (HCA) does not permit teaching performance to be associated with professors' qualification or workload.

Núcleo de Tecnologia Educacional de Terra Nova do Norte e a tecnologia educacional em construção : dificuldades e perspectivas

Este estudo foi realizado com o objetivo de conhecer e analisar como o Núcleo de Tecnologia Educacional de Terra Nova do Norte está capacitando os professores da rede pública de ensino em Informática da Educação; como essa capacitação é construída nos Laboratórios de Informática nas escolas; e como os professores estão fazendo uso do computador como ferramenta pedagógica. Pretendemos determinar quais são as dificuldades encontradas nesse tipo de capacitação, estabelecendo quais as reais perspectivas dos educadores e dos alunos do ensino fundamental; à luz dos resultados, elaboraremos um conjunto de sugestões com o intuito de melhorar o nível de qualidade de atuação dos envolvidos com tecnologia da informação e da comunicação. Além disso visitamos os núcleos de: Cuiabá, Cáceres, Diamantino, Nova Xavantina, Sinop e Terra Nova do Norte; os Laboratórios de Informática nos municípios de: Terra Nova do Norte, Colider, Itaúba, Claudia, Marcelândia, Feliz Natal e Sinop. Também visitamos os professores de sala de aula que atuam no Ensino Fundamental nessas escolas. Com dificuldades financeiras, sem meios de transporte próprio, com falta de pessoal técnico e especializado e com acumulo de funções e, conseqüentemente, sobrecarga de atividades, o Núcleo de Tecnologia Educacional de Terra Nova do Norte, através de seus especialistas, vem realizando um trabalho exaustivo, mas sem perspectiva: os cursos de capacitação relâmpagos não preparam os professores nem para funções elementares, muitos menos para funções complexas Para esses cursos, deve-se conceber uma carga horária mínima de 100 (Cem) horas/aula, resguardando a relação indissociável entre teoria e prática. A capacitação dos professores multiplicadores, que ainda acontece em nível básico, é a grande dificuldade que os especialistas do núcleo estão encontrando nesse processo, pois não há como dar uma boa capacitação em informática educacional se a maioria dos professores nunca sentaram em frente a um computador. Há necessidade de se rever com muito carinho esse processo de informatização das escolas públicas, tanto na dimensão epistemológica quanto na profissionalização. Há um grande compromisso e força de vontade do pessoal das escolas e dos núcleos, o que nos leva a afirmar que, se não fosse pela tenacidade desses professores o programa já estaria em fase terminal. O programa, portanto, necessita de mais apoio e de investimento em suas potencialidades técnica e pedagógica, pois do modo como está, pouco contribui para a democratização e a melhoria do ensino.

Isotopic evidence for the late Brasiliano (500-550 Ma) ore-forming mineralization of the Araes gold deposit, Brazil

The Araes gold deposit, located in eastern Mato Grosso State, central Brazil, is hosted in Neoproterozoic volcanosedimentary rocks of the Paraguay belt, which formed during collision of the Amazonian craton and the Rio Apa block. Ar-40/Ar-39 geochronology and Pb and S isotopic analyses constrain the timing and sources of mineralization. Three biotite flakes from two samples of metavolcanic host rock yield Ar-40/Ar-39 plateau ages between 5941 and 531 Ma, interpreted as cooling ages following regional metamorphism. Clay minerals from a hydrothermal alteration zone yield an Ar-40/Ar-39 integrated age of 503 +/- 3 Ma. Galena grains from ore-bearing veins yield values of Pb-206/(204)pb from 17.952 to 18.383, Pb-207/Pb-204 from 15.156 to 15.811, and Pb-208/Pb-204 from 38.072 to 39.681. Pyrite grains from ore-bearing veins yield values of Pb-206/Pb-204 from 18.037 to 18.202, Pb-207/Pb-204 from 15.744 to 15.901., and Pb-208/(204)pb from 38.338 to 38.800. Pb isotope variations may be explained in terms of mixing a less radiogenic lead component (mu similar to 8.4) from mafic and ultramafic basement host-rocks (Nova Xavantina metavolcanosedimentary rocks) and a more radiogenic lead component (mu similar to 9.2) probably derived from supracrustal rocks (Cuiaba sedimentary groups). Sulfur isotope compositions are homogeneous, with delta S-34 values ranging from -1.1 parts per thousand to 0.9 parts per thousand (galena) and -0.7 parts per thousand to 0.9 parts per thousand (pyrite), suggesting a mantle-derived reservoir for the mineralizing solutions. Based on the Ar, Pb, and S isotope data, we suggest that the precious metals were remobilized from metavolcanic host rocks by hydrothermal solutions during Brasilide-Panafrican regional metamorphism. The Arabs gold deposit probably formed during a late stage of the orogeny, coeval with other mineralization events in the Paraguay Belt.

First telemetry study of bush dogs: Home range, activity and habitat selection

Context The bush dog (Speothos venaticus) is difficult to observe, capture, and study. To date, indirect evidence and opportunistic field observations have been the primary sources of information about the species' ecology. Field data are urgently needed to clarify the species' ecological requirements, behaviour and movement patterns. Aims The present study uses 13 months of telemetry data from a group of bush dogs to begin to address questions about area requirements, habitat preferences and movement patterns of this difficult-to-study species. Methods We tracked a group of bush dogs (two adults, one juvenile, four young) in an area of intact and altered Cerrado (woodlandsavanna biome) in eastern Mato Grosso, Brazil (Nova Xavantina District). Key results The group had a total home range of 140km2 (fixed kernel 95%), with smaller seasonal 'subareas' (areas used for 12 months before moving to another area, with repetition of some areas over time) and demonstrated a preference for native habitats. Conclusions The bush dog's home range is greater than that of other canids of the same size, even correcting for group size. Patterns of seasonal movement are also different from what has been observed in other South American canids. Implications From our observations in the Brazilian savanna, bush dogs need large tracks of native habitat for their long-term persistence. Although the present study is based on a single pack, it is highly relevant for bush dog conservation because it provides novel information on the species' spatial requirements and habitat preferences. © 2012 CSIRO.

Give way to great charms of Halifax, Nova Scotia, Canada

A travel article about Halifax, Nova Scotia. MOTORISTS in Nova Scotia are so polite it's almost a shame to leave, writes Kari Gislason. By the end of my second day in Halifax, I begin to develop deep concerns about the safety of the locals, or the Haligonians as they're known. I wonder how they ever leave their fair city or, perhaps more to the point, how they ever make it back...

Experience the sights & sounds of Cape Breton, Nova Scotia

A travel article about Nova Scotia, and the area's annual Celtic music festival. I ARRIVED in Cape Breton on the occasion of the Fibre Festival, run not only by the South Haven Guild of Weavers but also the Baddeck Quilters Guild. And yet I might not have noticed that it was on, had it not been for a car, shrouded entirely by a quilt cover, that was parked outside the Volunteer Fire Department Hall. I was on my way to the Alexander Graham Bell Museum a little further along Baddeck's main street. But I stopped, for who wouldn't stop to look at the various fibres of Cape Breton. The hall had been divided between weavers and quilters. Naturally, I left hoping that one day this ancient divide might be healed...

Follow the lighthouse route in Nova Scotia, Canada

Within half an hour of leaving Halifax Airport I managed to get myself lost. I noticed an exit sign for St Margaret’s Bay and, despite written instructions to the contrary, it sounded like the right way to go. But I was on the Lighthouse Route and on my way back to Halifax...
