Desenhar no espaço : contributos para a construção da identidade do professor e artista, uma proposta para o 10º ano, Desenho A

Relatório da prática de ensino supervisionada, Ensino de Artes Visuais, Universidade de Lisboa, 2013O presente relatório resulta da análise da Unidade Didática Desenhar no Espaço, criada no âmbito do Mestrado em Ensino das Artes Visuais. A Unidade foi integrada na disciplina de Desenho A, e posta em prática com duas turmas do 10º ano do Curso de Artes Visuais da Escola Secundária Maria Amália Vaz de Carvalho, Lisboa. Com este projeto pretendeu-se explorar o desenho no espaço tridimensional, transpondo-se a utilização intencional e consciente dos elementos estruturais da linguagem do desenho, da superfície bidimensional para o espaço tridimensional da sala de aula. Concebeu-se uma sequência de exercícios que possibilitaram a construção e a partilha de novas consciências acerca do desenho, o que permitiu estabelecer a relação entre o desenho e outras áreas de expressão artística como a fotografia, a instalação ou a performance. Acredita-se que um ensino-aprendizagem do desenho que integre abordagens artísticas mais atuais ou contemporâneas é importante, não só para uma prática do desenho mais informada, mas também para uma compreensão e fruição mais abrangentes do desenho, o que impulsiona novas perspetivas para os percursos dos alunos nas artes plásticas. Através de uma pedagogia ativa, seguindo a linha das novas didáticas, e de acordo com uma perspetiva do ensino artístico em que o professor é simultaneamente artista, impulsionou-se a aprendizagem cooperativa e por descoberta, insistindo-se na concretização prática de conceitos, na atitude colaborativa e reflexiva. Considera-se que o sucesso efetivo do ensino e da aprendizagem resulta do pensamento acerca dos elementos que estruturam a ação didática num universo particular, de forma holística, bem como da criação de uma identidade como professor-artista, que se afirma numa prática reflexiva. Concluímos que a Unidade Didática Desenhar no Espaço contribuíu para uma aprendizagem coletiva, concretizada num projeto artístico de professores e de alunos, em que o desenho é trazido ao mundo através de uma prática consciente e de um olhar menos acomodado.This report results from the analysis of the Drawing in Space Didactic Unit, created under the Master in Teaching Visual Arts. This Unit was integrated in the Drawing course, and implemented with two classes of 10 th grade of the Visual Arts area, at Maria Amália Vaz de Carvalho High School, in Lisbon. This project was intended to explore drawing in three-dimensional space, transposing the intentional and conscious use of the structural elements of the language of drawing, from a two-dimensional surface to the three-dimensional space of the classroom. We conceived a sequence of exercises that enabled the creation and sharing of new consciousness in respect of drawing, which allowed for the establishment of a relationship between drawing and other areas of artistic expression such as photography, installation or performance. We believe that a teaching-learning process of drawing integrating artistic approaches more up-to-date or contemporary is important, not only to allow for a more informed practice of drawing, but also for a more comprehensive understanding and enjoyment of drawing, which boosts prospects for new paths of students in the arts. Through an active pedagogy, following the new didactics, and taking a perspective of arts education in which the teacher is simultaneously an artist, cooperative learning and discovery were boosted, while simultaneously insisting on the practical implementation of concepts in a collaborative and reflective attitude. We consider that the actual success of teaching and learning results of thinking about the elements that structure the didactic action in a particular universe, holistically, as well as of the creation of an identity as a teacher-artist, who performs a reflective practice. We conclude that the Drawing in Space Didactic Unit contributed to a collective learning experience, embodied in an artistic project of teachers and students, in which drawing was brought to the world through a conscious practice and a less accommodated view

Práticas artísticas no ensino básico e secundário

A matéria-prima de que trata esta revista é base de trabalho para um ensino artístico alargado, estendendo-se fora dos limites da aula, transgredindo os limites formais dos curricula, implicando património e riqueza cultural, sensibilizando para o imaterial, criando públicos apreciadores e também agentes criadores. É toda uma comunidade que se interliga através dos valores imateriais que sempre foram os da arte. A tarefa do educador é muito alargada: exige-se que esteja à altura deste desígnio humanista, que é também um desafio ao destino da humanidade: pela educação artística constroem-se futuros, e sem arte há intolerância, materialismo, indiferença, alienação, morte. Os tempos que se vivem são exigentes. As questões da pós modernidade estão muito acesas, desde as que nos obrigam ao desassossego, como a sustentabilidade e a poluição, como as que nos implicam politicamente, como a justiça, os direitos civis, a desigualdade. Tudo isto é matéria com a qual se amassa um barro que pode ser mais ou menos criativo: trata-se de extrair a matéria-prima com que se pode fazer os blocos que constroem o futuro. Aos profissionais da educação e do ensino, esta consciência, ao mesmo tempo desamparada – os cortes da economia neoliberal transformaram a arte em indústria, e a sua educação em criação de consumidores – e ao mesmo tempo vigilante e interventiva. Os artigos que responderam a esta chamada, respondem, cada um a seu modo, a este desassossego, a este desconforto, a este mal-estar contemporâneo. Dispuseram-se segundo uma sequência que se articula com base em temas afins que se podem descrever sucintamente: Todos os que participaram neste número mostraram a sua matéria-prima, a sua reação à falta que a arte nos faz. A chamada soa, e ressoa, e é necessário que seja por todos ouvida, em todos os países. É simples: as artes estão em perigo. Perigo porque há menos horas, menos professores, menos opções, menos conhecimento. As reduções no horário, a eliminação de disciplinas tão importantes como a história da arte, fazem de cada professor um agente da resistência, um ser mais implicado na sobrevivência da chama da criação. Matéria-prima: matéria para resgatar a verdade humana, a arte, a expressão mais valiosa da sua vaidade. Resgatar o homem que Michel Foucault (1988: 412) vê ameaçado, como um rosto na areia, desenhado à beira-mar.info:eu-repo/semantics/publishedVersio

NEOTROPICAL CARNIVORES: a data set on carnivore distribution in the Neotropics

Mammalian carnivores are considered a key group in maintaining ecological health and can indicate potential ecological integrity in landscapes where they occur. Carnivores also hold high conservation value and their habitat requirements can guide management and conservation plans. The order Carnivora has 84 species from 8 families in the Neotropical region: Canidae; Felidae; Mephitidae; Mustelidae; Otariidae; Phocidae; Procyonidae; and Ursidae. Herein, we include published and unpublished data on native terrestrial Neotropical carnivores (Canidae; Felidae; Mephitidae; Mustelidae; Procyonidae; and Ursidae). NEOTROPICAL CARNIVORES is a publicly available data set that includes 99,605 data entries from 35,511 unique georeferenced coordinates. Detection/non-detection and quantitative data were obtained from 1818 to 2018 by researchers, governmental agencies, non-governmental organizations, and private consultants. Data were collected using several methods including camera trapping, museum collections, roadkill, line transect, and opportunistic records. Literature (peer-reviewed and grey literature) from Portuguese, Spanish and English were incorporated in this compilation. Most of the data set consists of detection data entries (n = 79,343; 79.7%) but also includes non-detection data (n = 20,262; 20.3%). Of those, 43.3% also include count data (n = 43,151). The information available in NEOTROPICAL CARNIVORES will contribute to macroecological, ecological, and conservation questions in multiple spatio-temporal perspectives. As carnivores play key roles in trophic interactions, a better understanding of their distribution and habitat requirements are essential to establish conservation management plans and safeguard the future ecological health of Neotropical ecosystems. Our data paper, combined with other large-scale data sets, has great potential to clarify species distribution and related ecological processes within the Neotropics. There are no copyright restrictions and no restriction for using data from this data paper, as long as the data paper is cited as the source of the information used. We also request that users inform us of how they intend to use the data

Characterisation of microbial attack on archaeological bone

As part of an EU funded project to investigate the factors influencing bone preservation in the archaeological record, more than 250 bones from 41 archaeological sites in five countries spanning four climatic regions were studied for diagenetic alteration. Sites were selected to cover a range of environmental conditions and archaeological contexts. Microscopic and physical (mercury intrusion porosimetry) analyses of these bones revealed that the majority (68%) had suffered microbial attack. Furthermore, significant differences were found between animal and human bone in both the state of preservation and the type of microbial attack present. These differences in preservation might result from differences in early taphonomy of the bones. © 2003 Elsevier Science Ltd. All rights reserved

The conservation status of the world’s reptiles

Effective and targeted conservation action requires detailed information about species, their distribution, systematics and ecology as well as the distribution of threat processes which affect them. Knowledge of reptilian diversity remains surprisingly disparate, and innovative means of gaining rapid insight into the status of reptiles are needed in order to highlight urgent conservation cases and inform environmental policy with appropriate biodiversity information in a timely manner. We present the first ever global analysis of extinction risk in reptiles, based on a random representative sample of 1500 species (16% of all currently known species). To our knowledge, our results provide the first analysis of the global conservation status and distribution patterns of reptiles and the threats affecting them, highlighting conservation priorities and knowledge gaps which need to be addressed urgently to ensure the continued survival of the world’s reptiles. Nearly one in five reptilian species are threatened with extinction, with another one in five species classed as Data Deficient. The proportion of threatened reptile species is highest in freshwater environments, tropical regions and on oceanic islands, while data deficiency was highest in tropical areas, such as Central Africa and Southeast Asia, and among fossorial reptiles. Our results emphasise the need for research attention to be focussed on tropical areas which are experiencing the most dramatic rates of habitat loss, on fossorial reptiles for which there is a chronic lack of data, and on certain taxa such as snakes for which extinction risk may currently be underestimated due to lack of population information. Conservation actions specifically need to mitigate the effects of human-induced habitat loss and harvesting, which are the predominant threats to reptiles

Investigating the nature of the K∗0(700) state with π±K0S correlations at the LHC

The first measurements of femtoscopic correlations with the particle pair combinations π±K0S in pp collisions at s√=13 TeV at the Large Hadron Collider (LHC) are reported by the ALICE experiment. Using the femtoscopic approach, it is shown that it is possible to study the elusive K∗0(700) particle that has been considered a tetraquark candidate for over forty years. Boson source parameters and final-state interaction parameters are extracted by fitting a model assuming a Gaussian source to the experimentally measured two-particle correlation functions. The final-state interaction is modeled through a resonant scattering amplitude, defined in terms of a mass and a coupling parameter, decaying into a π±K0S pair. The extracted mass and Breit-Wigner width, derived from the coupling parameter, of the final-state interaction are found to be consistent with previous measurements of the K∗0(700). The small value and increasing behavior of the correlation strength with increasing source size support the hypothesis that the K∗0(700) is a four-quark state, i.e. a tetraquark state. This latter trend is also confirmed via a simple geometric model that assumes a tetraquark structure of the K∗0(700) resonance
