Mafalda na aula de História: a crítica aos elementos característicos da sociedade burguesa e a construção coletiva de sentidos contra-hegemônicos

A partir da leitura crítica de Mafalda, obra do cartunista argentino Quino, e alicerçados no conceito de hegemonia de Gramsci, sobretudo na noção de contra-hegemonia, buscamos analisar as possibilidades de se construir coletivamente sentidos contra-hegemônicos no ensino de História a partir do que chamamos de crítica aos elementos característicos da sociedade burguesa (a democracia, o individualismo, o estímulo ao consumo, a propriedade privada, a naturalização das diferenças, a competição, dentre outros). As contribuições de Gramsci ao campo da Educação, como o vínculo dialético entre as relações hegemônicas e pedagógicas, sua concepção da escola como um destacado aparelho privado de hegemonia, além das reflexões sobre os intelectuais e sua ação pedagógica na construção/difusão/legitimação de consensos, constituem pilares fundamentais das análises. É esforço fundamental da pesquisa identificar em que medida os professores, conscientes de seus vínculos de classe e compromissados com as classes dominadas, podem atuar como educadores-intelectuais orgânicos à estas classes, no âmbito da escola, tornando-a uma trincheira sob o conceito gramsciano de guerra de posição contra a hegemonia burguesa. Em termos metodológicos, foram selecionadas quinze tiras de Mafalda (divididas em onze temas os elementos que caracterizam a sociedade burguesa), presentes na obra Toda Mafalda (2002), no intuito de subsidiar as reflexões aqui esboçadas. Obviamente, todo recorte é ideológico e nenhuma escolha é neutra. As tiras escolhidas, longe de sintetizarem o olhar do artista argentino a respeito da burguesia, atendem aos objetivos deste trabalho.

The effect of diffusion and overhangs/vacancies on the microstructure of zig-zag thin film

Basing on some growth models of thin film, we have investigated the growth mechanism of glancing angle deposition (GLAD) film. The simulation verifies that the overhangs/vacancies also contribute to the columnar growth as well as the self-shadowing effect for GLAD thin film. Besides, we have studied the effect of the deposition rate, surface and bulk diffusions on the microstructure of thin film using the time-dependent Monte Carlo method. The results show that the surface and bulk diffusions can significantly enhance the packing density of thin film in GLAD growth, and the increase of the deposition rate induce the moderate decrease of the packing density.

Field validation of the 'Logie' fish counter at Forge weir on the River Lune, 1992

The stock assessment task group report (1991) mentions that fish counters could play a key role in providing data on the size of the adult stock, and in particular the migratory salmonid stock. This report assesses the performance of the 'logie' fish counter at Forge Weir on the River Lune. Using video surveillance, a total of 1137 hours time lapse and 15 hours real time were used for validation purposes. This report looks at materials and methods, counting accuracy, sizing ability and environmental conditions, performance across the electrode array and salmonid swimming speed.

Validation of the performance of the Aquantic 2100A fish counter

This report looks at the validation of the performance of the Logie 2100A fish counter which was carried out at Forge Weir (River Lune) and Gunnislake Fish Pass (River Tamar), using a video recording system.

Description of NRA tracking studies: tracking techniques and fish counter technology

The study began on the 7th January 1991 and was completed in June 1991. Two reports have been produced. This report published as R&D Note 33 describes NRA tracking studies, tracking techniques and fish counter technology. The second report published as R&D Note 34 evaluates NRA tracking studies and recommends future research. The latter will be used solely for NRA management purposes. This report briefly outlines the programme of the NRA, placing the Fisheries programme in the context of the work of the NRA as a whole, and viewing the tracking work against the broader requirements of the NRA Fisheries research programme. Two techniques currently exist for studying the detailed timing and extent of movements of adult salmon: tracking of individually identifiable fish, and counting the numbers of fish moving past a fixed point in the river. Further details of these techniques and their development are given in Sections 2 and 3. Section 4 summarises and assesses completed and current NRA tracking Studies. Complete project descriptions for the studies are contained in Appendix A. Section 5 discusses the scientific content of these studies in relation to similar work carried out elsewhere in the UK. Section 6 details the future development of tracking techniques. Tracking work on migratory salmonids has tended to concentrate largely upon the movements of adult salmon. Much of this report will therefore be concerned with salmon tracking studies. NRA studies involving sea trout are referred to where appropriate. The methodological problems of sea trout tracking studies are summarised in Section 2.1.3.
