No full textInternational audienceIn this paper, we aim to address the debut novel Terra Fria by the Portuguese descendant Ana Maria Torres, written and published in French in 2022. In a village in the north of Portugal, in the eastern part of Trás-Os-Montes, the conflictual trajectories, perspectives, childhood memories and origins of two women, Madalena and Marta, mother and daughter, take shape. One wants to pursue a better life by emigrating to France, the other wants to return to the place where her roots are inscribed. In a very concise way, between myths and mythologies, sayings, knowledge and flavors, it is depicted a way of life which encompasses the village, the house, domestic work, such as making bread, agricultural work with its various cycles, but also festivals and initiation rites - a world on the brink of collapse and of being devoured by oblivion. But it is also a portrait of Portugal drawn in filigree: the situation of women in a system dominated by patriarchy, poverty, emigration and which seems not to have been touched by the April Revolution. The writing is lean, dense and made with great poetic restraint, not dwelling on details, in order to capture only the essential, through chapters that mirror each other, which portraits Portuguese realities and even goes beyond them, reaching a more intimate, profound and universal world, so much to the liking of the great master from Trás-os-Montes, Miguel Torga, author of the book's epigraph. With a very elaborate writing, Ana Maria Torres presents us with a palette of colors, smells, images, rumours, only possible due to the transfigurative mastery of the writer. After an analysis of the axes outlined above, we will try to demonstrate how these voices of female characters convey not only their identity, but also form part of a community of citizens who try to preserve their roots despite everything that disappears.Propomo-nos abordar nesta comunicação o romance de estreia Terra Fria da lusodescendente Ana Maria Torres, escrito e publicado em francês em 2022. Numa aldeia do norte de Portugal, na parte oriental de Trás-Os-Montes, confrontam-se os percursos, os olhares, as memórias da infância e das origens de duas mulheres, Madalena e Marta, mãe e filha. Uma deseja partir para uma vida melhor emigrando para França, a outra deseja regressar ao lugar onde se inscrevem as suas raízes. De forma muito concisa, entre mitos e mitologias, dizeres, saberes e sabores, desfila um modo de vida que passa em revista a aldeia, a casa, os trabalhos domésticos, como o fazer do pão, a faina agrícola com os seus diversos ciclos, mas também as festas e os ritos de inicição, um mundo que tende a desmoronar-se e a ser devorado pelo esquecimento. Mas é também um retrato de Portugal que se desenha em filigrana: a situação das mulheres num sistema onde reina o patriarcado, a pobreza, a emigração, no qual a Revolução de Abril não parece ter passado. A escrita é enxuta, densa e com grande contenção poética não se demorando em pormenores para captar apenas o essencial, através de capítulos espelhados, que captam não só realidades portuguesas mas que as ultrapassam para atingir um mundo mais íntimo, profundo, que atinge o universal, tão ao gosto do grande mestre transmontano, Miguel Torga, autor da epígrafe do livro. Com uma escrita muito elaborada, Ana Maria Torres coloca-nos diante dos olhos uma paleta de cores, odores, imagens, rumores, só possíveis graças à sua mestria transfiguradora. Após uma análise dos eixos acima esboçados procuraremos demonstrar de que forma estas vozes das personagens femininas veiculam não só a sua identidade, como se inscrevem numa comunidade de cidadãos que tenta preservar as raízes apesar de tudo o que desaparece
Computable Queries for Object Oriented Databases
No full textAbstractA relational database can be considered as a finite structure for a finite relational signature in first-order logic, i.e., there are no function symbols. Interpreting the logic over this signature in such structures allows the expressiveness and complexity of queries to be studied in detail. This is the starting point for finite model theory which has proven to be a viable tool to study relational database theory. In particular, it is known that computable queries expressed as isomorphism-preserving partial recursive functions can be formalized by Reflective Relational Machines. These are extended Turing Machines with an additional relational store, a query tape and the facility to evaluate the query on the tape against the database in the store in a single step.In this paper we start to generalize the theory to post-relational databases. We first consider the case of having set-based complex values and references such that the semantics can still be expressed in finite sets. Following the approach that object oriented databases in general including those, where the underlying type systems does no longer allow the semantics defined by sets, can be expressed as theories in higher-order intuitionistic logic, we use such a logic instead of first-order logic. However, as we are not yet exploiting the full power of such logics, we can interpret the logic in the category FINSET of finite sets, i.e., again in a structure defined by a database.Having done this the definition of computable queries and the model of Reflective Relational Machines carry over easily. We can show that the new model of Reflective Object Machines guarantees completeness, i.e., all computable queries can be expressed by the model
The Space Complexity of Elimination Theory: Upper Bounds
No full textWe use a theorem by Borodin relating parallel time with sequential space in order to obtain algorithms that require small space resources. We rst apply this idea to some linear algebra problems. Then we reduce several problems of Elimination Theory to linear algebra computations and establish PSPACE bounds for all of them. Finally, we show how this strategy can be improved by means of probabilistic arguments
O mundo do capitalismo cognitivo depende da instrumentalização do sistema educacional.
No full textJurjo Torres Santomé (1951) is a pedagogue and teacher at the University of A Coruña (Spain). His extensive experience in the field of education, his commitment to an education that prioritizes social justice and his research on the hidden curriculum, textbooks or the neoliberal influence on the educational system, have made him an international benchmark.
Author of dozens of books and scientific articles, Jurjo has been working in recent years with special emphasis on how the education system works as a fundamental collaborator in the construction of neoliberal and neocolonial subjectivities, producing societies where the self-interest of the subjects is above of the common good, resulting in the increase of inequalities in the world and within countries.
Today we have the opportunity to talk at length with him to deepen some of these issues and other issues of educational relevance.Jurjo Torres Santomé (1951) es pedagogo y docente en la Universidade da Coruña. Su dilatada experiencia en el campo educativo, su compromiso por una educación que priorice la justicia social y sus investigaciones acerca del currículum oculto, los libros de texto o la influencia neoliberal sobre el sistema educativo, lo han convertido en un referente a nivel internacional.
Autor de decenas de libros y artículos científicos, Jurjo viene trabajando en los últimos años con especial incidencia sobre cómo el sistema educativo ejerce de colaborador fundamental en la construcción de subjetividades neoliberales y neocolonialistas, produciendo sociedades donde el interés propio de los sujetos se sitúa por encima del bien común, dando como resultado el aumento de las desigualdades en el mundo y en el interior de los países.

The fellowship of St.Diogo : new Christian judaisers in Coimbra in the early 17th century
No full textDr Antonio Homem was a respected teacher in the University of Coimbra, a Canon in the Cathedral and an illustrious scholar. He was also the heir of a long Jewish family tradition. His great-great-grand father lived and died as a Jew. His great-grandfather, his grandmother and two of his uncles were among his relatives to have been sentenced
as judaisers by the Inquisition. His own father kept the Law of Moses, and taught it to all his children, without the knowledge of his wife, an Old Christian of noble lineage.
His concern for the situation of the New Christians in Portugal eventually made him build up a congregation of judaisers, which he called the Fellowship of St Diogo as a tribute to a Capuchin friar who had been executed a few years earlier as an apostate and defender of the Jewish Law. His congregation grew to include over sixty people,
including clerics, physicians, lawyers and students, as well as merchants and farmers. Its leader gave it a corpus of doctrine and eventually a distinctive liturgy, which showed influence from the Catholic Church. The Fellowship also inspired the creation of judaiser conventicles
in three major Monasteries in the Coimbra district, where a relatively large number of nuns held cult meetings and paid homage to Friar Diogo as a martyr of the Law of Moses.
After several years of activity, the Fellowship was investigated and dismantled by the Inquisition. Most of its members were arrested and sentenced. Dr AntOnio Homem was himself taken into custody, charged with heresy and apostasy, as well as sodomy (he was a known paederast), and finally handed over to the secular arm for execution.
His dream of building up a judaiser community in Coimbra was shattered. The Fellowship members who survived either left the country and joined the orthodox Jewish communities in the Netherlands and elsewhere, or stayed in Portugal and gradually lost their Jewish consciousness. Descendants
of some of them can still be found near Coimbra
Descriptive complexity of deterministic polylogarithmic time and space
No full textWe propose logical characterizations of problems solvable in deterministic polylogarithmic time (PolylogTime) and polylogarithmic space (PolylogSpace). We introduce a novel two sorted logic that separates the elements of the input domain from the bit positions needed to address these elements. We prove that the inflationary and partial fixed point variants of this logic capture PolylogTime and PolylogSpace, respectively. In the course of proving that our logic indeed captures PolylogTime on finite ordered structures, we introduce a variant of random-access Turing machines that can access the relations and functions of a structure directly. We investigate whether an explicit predicate for the ordering of the domain is needed in our PolylogTime logic. Finally, we present the open problem of finding an exact characterization of order-invariant queries in PolylogTime. (C) 2021 Elsevier Inc.
