  1. Géneros populares y cine transnacional en la Europa mediterránea: André Hunebelle y el cine de aventuras

    Carrega, Jorge
    Entre mediados de los años cincuenta y setenta, la inversión en la coproducción cinematográfica entre los países de la Europa mediterránea condujo al desarrollo del género popular como la película de capa y espada, peplum y euro-western. A menudo analizadas desde una perspectiva puramente nacional, estas películas representan, sin embargo, un ejemplo paradigmático de cine transnacional que permitió a las industrias cinematográficas italianas, francesas y españolas combatir la hegemonía comercial del cine de Hollywood. Basado en el estudio de un caso, el de la carrera del director André Hunebelle, este artículo propone analizar el papel de la coproducción de películas de aventuras en el desarrollo...

  2. Problem based learning. A brief review

    Nunes, Sandra; Oliveira, Teresa A.; Oliveira, Amílcar
    Teaching is a complex mission that requires not only the theoretical knowledge transmission, but furthermore requires to provide the students the necessary skills for solving real problems in their respective professional activities where complex issues and problems must be frequently faced. Over more than twenty years we have been experiencing an increase in scholar failure in the scientific area of mathematics, which means that Teaching Mathematics and related areas can be even a more complex and hard task. Scholar failure is a complex phenomenon that depends on various factors as social factors, scholar factors or biophysical factors. After numerous attempts...

  3. Item response theory. A first approach

    Nunes, Sandra; Oliveira, Teresa; Oliveira, Amílcar
    The Item Response Theory (IRT) has become one of the most popular scoring frameworks for measurement data, frequently used in computerized adaptive testing, cognitively diagnostic assessment and test equating. According to Andrade et al. (2000), IRT can be defined as a set of mathematical models (Item Response Models – IRM) constructed to represent the probability of an individual giving the right answer to an item of a particular test. The number of Item Responsible Models available to measurement analysis has increased considerably in the last fifteen years due to increasing computer power and due to a demand for accuracy and...

  4. “Epa, meu futuro fica a cada dia mais incerto”: perspectivas de futuro através da trilha sonora e do discurso da criança nas representações pós-coloniais do filme "Os Olhos Azuis de Yonta" (1992), de Flora Gomes

    Oliveira, Jusciele
    O filme Os olhos azuis de Yonta (Udju azul di Yonta – 1992) é o segundo longa-metragem de ficção do cineasta bissau-guineense Flora Gomes. O drama narra a história das diferentes gerações que viveram o colonial, o pós-colonial e o neocolonial pelas vidas das personagens Yonta, Zé, Vicente e Amilcarzinho, perpassando pela história política, econômica, social, artística e cultural da Guiné-Bissau. Analisam-se os seguintes componentes: trilha sonora, a perspectiva de futuro por meio do discurso/fala da criança Amil- carzinho e Guiné-Bissau. Para tal, foram utilizados como suporte teórico textos críticos sobre os cinemas africanos, especialmente dos países de língua oficial...

  5. Smart cities, smart tourism? The case of the city of Porto

    Guerra, I.; Borges, F.; Padrão, J.; Tavares, J.; Padrão, M. H.
    The so-called Smart Cities have been playing an important role in the academic literature as well as in the agenda of public policies. With the forward thinking of “creating” new urban development models, the cities intend to strategically positioning themselves and at the same time develop cooperation networks. Frequently using the Information and Communication Technologies (while as a means to an end and not as an end itself), the cities try to assure a greater economic competitiveness, the environmental sustainability and the reinforcement of citizenship (calling out to people to participate, in the scope of an inclusive logic and in...

  6. Aventuras em technicolor: paraliteratura e cinema transnacional na Europa Mediterrânea

    Carrega, Jorge
    A aposta dos países da Europa mediterrânea na coprodução cinematográfica permitiu, entre meados das décadas de 1950 e 1970, o florescimento de gêneros populares como o filme de capa e espada, o peplum e o filme policial, que adaptaram ao cinema a obra de autores como Alexandre Dumas, Emilio Salgari, Paul Féval e Georges Simenon. Frequentemente analisados numa perspetiva puramente nacional, estes filmes representam contudo o exemplo paradigmático do desenvolvimento de um cinema transnacional, que permitiu às indústrias cinematográficas italiana, francesa e espanhola, contrariar a hegemonia comercial do cinema de Hollywood. Este artigo procura analisar a importância da chamada paraliteratura,...

  7. Mortu nega (1988): cinema e história na luta de independência e o pós-colonial “daqueles a quem a morte foi negada”

    Oliveira, Jusciele Conceição Almeida de
    As relações entre Portugal e o território que corresponde à atual Guiné-Bissau datam do século XV. Com a chegada de Diogo Gomes na costa africana, as relações territoriais, políticas e culturais se intensificaram. Entre 1884 e 1885, após a Conferência de Berlim, foram delimitadas as fronteiras físicas do continente africano. Em janeiro de 1963, deflagrou-se a luta da Guiné pela independência contra o colonialismo português, que só será reconhecida oficialmente por Portugal depois do 25 de abril de 1974. Nesse sentido, a história de Portugal e da Guiné-Bissau se cruza, razão pela qual é feito neste texto um levantamento sobre...

  8. An efficient parallel collision detection algorithm for virtual prototype environments

    Figueiredo, Mauro; Terrence, Fernando
    The automatic recognition of geometric constraints in virtual assembly and maintenance operations relies in the determination of intersecting surfaces between virtual prototypes. This is a key challenge in many virtual prototype applications, where it is necessary to find collisions precisely and interactively. This paper presents a novel algorithm to determine intersecting surfaces at interactive speed in a virtual prototyping environment. The proposed algorithm is based on the Overlapping AxisAligned Bounding Box (OAABB). The OAABB concept is used effectively to eliminate the number of surfaces that cannot intersect and improve performance. The algorithm also facilitates the implementation using parallel computing methods. OpenMP is used, taking advantage of shared memory multiple processors and reducing the overall time...

  9. Recensão a Jacques Rancière, os intervalos do cinema

    Soares, Ana Isabel
    (Quando li pela primeira vez um ensaio de Jacques Rancière, lembro-me, pensei em Sebastião da Gama. Não é tão distante o tiro: a ideia de saber, em Gama, é a ideia daquilo que procura o mestre desconhecedor. Mas talvez o que mais tivesse aproximado aquelas duas figuras, na minha leitura, fosse um certo posicionamento, de ambos, perante o que pretendem conhecer. As explorações da sala, de cada um dos rostos dos seus alunos, fazem de Gama o “incapaz como tal” que constitui o explicador no relato sobre a “aventura intelectual” de Joseph Jacotot, tal como Rancière a narrou no começo...

  10. Tempo e conceitos em Hans Ulrich Gumbrecht

    Soares, Ana Isabel
    Entre as páginas do exemplar de Produção de Presença que tenho comigo, guardo duas folhas, com impressões a cores de outros tantos artigos que Hans Gumbrecht publicou n’O Estado de São Paulo, em fevereiro e em março de 2009. Um debruça-se sobre “A crise de um futebol sem rosto”, título que discute a fraca prestação da seleção canarinha nos jogos de preparação para o Mundial de 2010; no outro artigo, anterior àquele, em pouco mais de três colunas, traça-se o quadro de uma cultura desaparecida: o ideal comunista de Leon Trotsky.

  11. Cinema português/cinema literário?

    Soares, Ana Isabel
    Antes de refletir sobre o carácter adjetival presente no segundo termo do título, sugiro que se pense em como os nomes “literatura” e “cinema” frequentemente integram expressões mediadas por uma conjunção ou por locuções preposicionais: Literatura e Cinema, Cinema na Literatura, O Cinema da Literatura, enfim, a série de possíveis combinações e as adjetivações possíveis que, pela proximidade dos termos, delas deriva. Qualificar “cinema” como “literário” implica, desde logo, um entendimento (em separado) daquilo que é fílmico e daquilo que é literário. Só então se torna possível teorizar uma eventual relação entre ambos, uma expressão que sugira, do começo, a...

  12. A musicalidade africana narra a vida de vita na comédia-musical nha fala do cineasta Flora Gomes

    Oliveira, Jusciele
    O filme Nha fala (2002), uma comédia-musical, do cineasta Flora Gomes, narra parte da história de Vita, uma jovem guineense, que carrega uma maldição familiar, que proíbe que as mulheres de sua família cantem e, caso essa lei seja descumprida, elas morrerão. No entanto, ao viajar para estudar na França e apaixonar-se por Pierre, canta, conhece o sucesso e resolve voltar para a Guiné-Bissau, para realizar o seu próprio funeral. O presente ensaio, centra-se na análise do filme Nha fala, enfocando inicialmente na discussão sobre gêneros cinematográficos e depois na musicalidade africana e, em especial, as músicas que compõem o...

    Figueiredo, Mauro; Jesus, Saul; Duarte, Duarte; Cabral, Fernando
    With a background in conceptual art and media art, and the relations between science and art, we tried to approach the concept of stress through art. Stress is a recent problem of people in several countries, and could be caused by external factors, such as social pressure, or be derived from internal factors, such as the requirement that the subject puts himself. Stress had a negative impact at several organs of the human body, but heart is the main one. Taking into account all of these aspects, and from photos of two drawings of the heart ?????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????? setup program EDIUS, that integrate...

  16. A topological framework for interactive queries on 3D models in the web

    Figueiredo, Mauro; Rodrigues, J. I.; Silvestre, Ivo; Veiga-Pires, C.
    Several technologies exist to create 3D content for the web. With X3D, WebGL, and X3DOM, it is possible to visualize and interact with 3D models in a web browser. Frequently, three-dimensional objects are stored using the X3D file format for the web. However, there is no explicit topological information, which makes it difficult to design fast algorithms for applications that require adjacency and incidence data. This paper presents a new open source toolkit TopTri (Topological model for Triangle meshes) for Web3D servers that builds the topological model for triangular meshes of manifold or nonmanifold models. Web3D client applications using this...

  17. Surface collision detection for virtual prototyping

    Figueiredo, Mauro
    This paper presents an efficient collision detection algorithm designed to support assembly and maintenance simulation of complex assemblies. This approach exploits the surface knowledge, available from CAD models, to determine intersecting surfaces. It proposes a novel combination of Overlapping Axis-Aligned Bounding Box (OAABB) and R-tree structures to gain considerable performance improvements. This paper also shows an efficient traversal algorithm based on the R-tree structure of Axis-Aligned Bounding Boxes to determine intersecting objects and intersecting surfaces between three-dimensional components, for supporting the recognition of constraints in assembly and disassembly operations in virtual prototyping environments. The implementation of the proposed collision detection algorithm...
