‘Crows’ vs. ‘Avatar’, or: 3D vs. total-dimensional immersion

3D film’s explicit new space depth arguably provides both an enhanced realistic quality to the image and a wealth of more acute visual and haptic sensations (a ‘montage of attractions’) to the increasingly involved spectator. But David Cronenberg’s related ironic remark that ‘cinema as such is from the outset a «special effect»’ should warn us against the geometrical naiveté of such assumptions, within a Cartesian ocularcentric tradition for long overcome by Merleau-Ponty’s embodiment of perception and Deleuze’s notion of the self-consistency of the artistic sensation and space. Indeed, ‘2D’ traditional cinema already provides the accomplished «fourth wall effect», enclosing the beholder behind his back within a space that no longer belongs to the screen (nor to ‘reality’) as such, and therefore is no longer ‘illusorily’ two-dimensional. This kind of totally absorbing, ‘dream-like’ space, metaphorical for both painting and cinema, is illustrated by the episode ‘Crows’ in Kurosawa’s Dreams. Such a space requires the actual effacement of the empirical status of spectator, screen and film as separate dimensions, and it is precisely the 3D caracteristic unfolding of merely frontal space layers (and film events) out of the screen towards us (and sometimes above the heads of the spectators before us) that reinstalls at the core of the film-viewing phenomenon a regressive struggle with reality and with different degrees of realism, originally overcome by film since the Lumière’s Arrival of a Train at Ciotat seminal demonstration. Through an analysis of crucial aspects in Avatar and the recent Cave of Forgotten Dreams, both dealing with historical and ontological deepening processes of ‘going inside’, we shall try to show how the formal and technically advanced component of those 3D-depth films impairs, on the contrary, their apparent conceptual purpose on the level of contents, and we will assume, drawing on Merleau-Ponty and Deleuze, that this technological mistake is due to a lack of recognition of the nature of perception and sensation in relation to space and human experience.

A relação diagnóstica em contexto de creche e jardim-de-infância

O presente estudo enquadra-se no domínio das Ciências da Educação e na área específica da Análise da Acão Educativa. Não se afastando das preocupações inscritas nos objetivos de um mestrado de autor "A Criança em Diferentes Contextos Educativos”, também se compagina com as nossas determinações pessoais e profissionais, empreendidas na convicção da investigação como um projeto de vida. Para o efeito, arquitetámos o nosso universo de estudo a partir da observação naturalista em sete salas de creche e de jardim-de-infância do distrito de Évora. Da população estudada fizeram parte diferentes acores educativos, entre eles, as crianças dos 3 meses aos 6 anos de idade, as educadoras e as auxiliares de Acão educativa. Pretendemos, a partir dos sinais emitidos pelas crianças, retirar indicadores de necessidades educativas, para compreender as atitudes e comportamentos dos agentes educativos (educadores e auxiliares) na sua prática pedagógica, inferindo das suas próprias necessidades formativas. Procurámos saber como eram feitos os diagnósticos de necessidades (educativas das crianças e formativas dos educadores) e como organizavam a sua relação com outros acores educativos, no sentido de um desenvolvimento holístico da criança. Dada a natureza e o objeto de estudo, optámos por uma metodologia qualitativa de carácter interpretativo, configurada num estudo de caso. Utilizámos a linha de Investigação-Acão/Formação, preconizada por Luís Barbosa, integrada na sua "Escola Sensível e Transformacionista", que radica os seus fundamentos na ideia de que o jardim-de-infância, tal como outra qualquer organização educativa, deve ser um "Observatório de Caracterização de necessidades educativas das crianças e formativas dos sues agentes educativos”, gerido na perspetiva da mudança. Neste enquadramento de ideias, ao qual aderimos por convicção, utilizámos, para caracterizar o real, a Observação como técnica privilegiada, pese embora as limitações que lhe são subjacentes. Minimizámos este facto, triangulando os dados com entrevistas semiestruturadas e notas de campo. Suportámo-nos da Técnica do Espelhamento, da Pedagogia de Ajuda, da Renomeação de Experiências e da Extensibilidade de Si, às quais, pela sua importância demos ênfase no enquadramento teórico. O nosso estudo permitiu-nos inferir que, a relação diagnostica nos processos de ensino/aprendizagem, naqueles contextos, parece estar correlacionada com o facto de que os agentes educativos ainda necessitam de adquirir um leque variado de competências, relacionadas com o Saber-Ser e o Saber-Estar, que lhes permitam atitudes relacionais pró-activas e maior sensibilidade para captar as emoções e as sensações das crianças. Este facto vem corroborar o facto de termos verificado que os agentes educativos não usam o diagnóstico de necessidades como âncora de organização das suas práticas educativas o que não contribui de forma sustentável para a promoção do bem-estar e do desenvolvimento integral da criança. ABSTRACT: The present study lies within the field of Educational Sciences in the specific area of analysis of education. Not moving away from the concerns listed in the goals of an author master degree "The Child in Different Educational Contexts”, it also fits our personal and professional decisions, undertaken in the belief of research as a project of life. We chose the universe of our study from naturalistic observation in seven rooms of Nurseries and Infant Schools in the district of Évora. The study population consisted of children from three months to six years old, educators and assistants of education. From signals emitted by children, we intended to take indicators of educational needs to understand the attitudes and behavior of the educators and their assistants in their pedagogical practice, inferring their own educational needs. We tried to know how the diagnoses of needs were made (educational needs of the children and training needs of the educators) and how they organized their relationship with other educational agents towards a holistic development of children. Considering the nature and purpose of the study we opted for a qualitative methodology of interpretative nature, in a case study. We used the action research training line, advocated by Luís Barbosa in his work "Escola Sensível e Transformacionista" (Sensitive and Transformational School), whose reason lies in the idea that Infant Schools, like other educational organizations, should be centers for the characterization of children’s educational needs and educational agents' formative needs, managed in terms of change. ln this framework of ideas, that we adopted by conviction, we used the observation as the main technique, despite its limitations. To minimize them we triangulated the data with semi structured interviews and field notes. We used the techniques of Mirroring, Pedagogy of Help, renaming of Experiences and Extensibility of Yourself, and, because of their importance, we focused on them in the theoretical framework. This study allowed us to infer that the diagnostic relationship in the teaching­learning processes, in those contexts, seem to be correlated with the fact that the educational agents still need to acquire a wide range of skills related to the Know How To Be, to provide them with proactive relational attitudes and a bigger sensibility to get the children's emotions and sensations. We also found that the educational agents don't use a diagnostic of needs as anchor of the organization of their educational practices, what does not contribute in a sustainable way for the promotion of the well being and integral development of the child.

Por baixo da pele outra pele: conjunto de obras artísticas. Corpo, ecrã e interface para uma visualidade háptica interativa

A tese teórico-prática de doutoramento apresentada contempla a investigação, a criação, a produção e a conceptualização da instalação artística interativa intitulada Por baixo da pele outra pele. A Obra é constituída por três objetos tridimensionais concebidos à escala humana. Recorre a materiais flexíveis, como têxteis, convidando o público (interator), à envolvência física, numa relação corporal sensorial e sensual com a obra. Os objetos contêm dispositivos técnicos interativos e sensores tácteis, que, ao serem utilizados, desencadeiam estímulos multissensoriais no espectador. A instalação interativa focaliza a experiência háptica e íntima do interator considerando os seus mecanismos sensoriais e cognitivos como um potencial aparato na construção de experiências fenomenológicas, singulares e individuais. A autora considera a interatividade enquanto elemento potenciador da experiência estética visual háptica. Na argumentação conceitual da obra, reflete-se sobre o tema da visualidade háptica interativa a partirdos conceitos de ecrã, corpo e interface, assim como de endossensorialidade. Instrumentam-se metodologias de investigação em ação, experimentais e observacionais. Apresentam-se os processos investigativos, criativos e técnicos necessários ao desenvolvimento e à materialização da instalação artística. A investigação revela-se de grande interesse para o avanço da pesquisa de novas linguagens experimentais apresentando estratégias de criação artística que, ao privilegiarem o corpo físico e fenomenológico do interator, transpõe a experiência háptica interativa para um grau interno de imersão motoro-sensorial; Underneath the skin another skin: art installation. Body, screen and interface towards an interactive haptic visuality. Abstract: The theoretical-practical doctorate dissertation presents the research and conceptual framework behind, and the processes leading to, the creation and production of the interactive installation art piece Underneath the skin, another skin. The piece is presented in the shape of three human-scale tridimentional objects. It is made from flexible materials, such as textiles, inviting the (interacting) audience, to physically engage in a bodily sensorial, and sensuous, relationship with the artwork. The objects enclose interactive devices and tactile sensors that, when used, trigger in the interactor multiple sensorial stimuli. The interactive installation focuses on the interactor's intimate haptic experience taking in consideration his or hers sensorial and cognitive mechanisms as a potential apparatus in the construction of unique individual phenomenological experiences. The author understands interactivity as a triggering element into an haptic visual aesthetical experience. The supporting conceptual reasoning deals with thought and criticism on interactive haptic visuality applied to the concepts of screen, body and interface, as well as with that of endo-sensoriality. The dissertation describes the use of experimental and observation research methodologies. It also elaborates on the research, creative and technical processes at play in the installation's development and realization. The research at hand has shown great potential for the further development of new experimental languages, as it presents art-creation strategies privileging the interactor's physical and phenomenological body, and thus able to take the interactive haptic experience onto an greater inner level of motor-sensorial immersion.

Oral food perception and polyphenol-rich foods acceptance - the importance of knowing individuals saliva characteristics for promoting consumption

Polyphenols are widely present in fruits, vegetables, cereals and beverages. Their study gained scientific interest because of their beneficial effects on health. Although there is currently no official dietary recommendation for polyphenol intake, health professionals recommend the consumption of 5-8 daily portions of fruits and vegetables. This is not always achieved and, despite possible causes associated to practical schedule difficulties, the aversive bitter and astringent sensations associated to polyphenols may also lead to avoidance. As such, a better understanding on mechanisms responsible for differences among people, in polyphenol oral perception, is needed for promoting healthier choices. Saliva has been linked to polyphenol consumption. We have previously observed, in animal models, changes in salivary proteome induced by tannin-enriched diets. Moreover, differences in astringency perception were attributed to differences in salivary protein composition. In a recent experiment, we observed differences among individuals with dissimilar tannic-acid perception: people with high sensitivity for the oral sensations elicited by tannins have higher amounts of salivary cystatins and lower capacity to maintain their levels after tannic-acid ingestion. Additionally, and similarly to previous studies, salivary amylase was observed to be involved in tannin perception. In this presentation, oral cavity characteristics influencing the perception of polyphenol-containing foods will be discussed.
