Los personajes como elemento transgresor en los productos culturales: análisis de “¿Qué hora es?” de Elena Garro
No full textThe present work explores the elements that shape the features of the characters created by the Mexican author Elena Garro and define her production; characters who transgress established orders, the compliance of norms and values. It is the interest of this work to make inquiries on the shaping of characters as literary elements, whose significance in the narrative of Elena Garro may signal one of the characteristics that define her narrative and her value as a 20th Century author: transgression. In particular, the short story “¿Qué hora es? [What time is it?], in which Lucia Mitre will transgress her role of an adulterous woman, apparently neglected in her space-time dimension, is analyzed, as well as the thematic role of the characters.El presente trabajo explora los rasgos que configuran a los personajes del cuento de la autora mexicana Elena Garro. Se plantea indagar en la configuración del personaje como un elemento literario, cuyas características se definen con la trasgresión. En particular, se analiza el cuento “¿Qué hora es?”, incluido en La semana de colores, en el que Lucía Mitre traza una ruptura en el rol de la mujer adúltera y, aparentemente, desamparada en una dimensión espaciotemporal infringida y, hasta cierto punto, fragmentada
Cristales de tiempo: Los poemas transgresores de Elena Garro
No full textJoin us for a presentation in the Fall 2017 LAII Lecture Series as we hear from Dr. Patricia Rosas Lopátegui, an Assistant Professor in the UNM Department of Chicana and Chicano Studies.
Lopátegui teaches courses on Literature and Journalism in Mexico, Chicano and World Cinema, and Transgressive Women in Mexican Literature, among others. Her work focuses on the preservation and publication of the writings of Mexican women authors, particularly that of Elena Garro, but also Nahui Olin and recently Guadalupe Dueñas. Her publish work includes the recent biography, El asesinato de Elna Garro. Periodismo a través de una perspectiva biográfica (2014), and the compilation Óyeme con los ojos. De Sor Juana al siglo XXI. 21 escritoras mexicanas revolucionarias, among others. In this presentation, Lopátegui will address the poetry of Elena Garro, a transgressive and pioneering Mexican author whose feminist writings confronted patriarchy in 20th century Mexico.https://digitalrepository.unm.edu/laii_events/1055/thumbnail.jp
Friar Lourenço Garro, Bishop of Santiago, the true author of a 17th century anti-slavery text
No full textUID/HIS/04666/2013O tema do artigo é uma carta, sem data nem autor, dirigida a um dos reis de Portugal por um bispo de Santiago de Cabo Verde, condenando o tráfico negreiro promovido pelos Portugueses e propondo a libertação dos escravos batizados. O documento tem sido, até agora, atribuído ao bispo D. Pedro Brandão, presente naquela diocese nos últimos anos do século XVI, autoria que aqui se contesta, defendendo-se que foi o bispo D. Lourenço Garro o verdadeiro autor da carta, que a deverá ter escrito nos anos quarenta do século XVII. Procura-se também enquadrar o documento na literatura antiesclavagista portuguesa e castelhana dessas duas centúrias. This article concerns a letter sent by a Cape Verde bishop to the king of Portugal. The subject matter of this letter was both to condemn the slave trade and to propose the liberation of slaves whenever they were christened. The document has been attributed to the Bishop Pedro Brand.o, who lived in Cape Verde during the last years of the sixteenth century. This article proposes Bishop Louren.o Garro as the letter’s real author, who probably wrote it in the 1640s. The article also integrates the letter into the Portuguese and Spanish anti-slave trade literatures of those centuries.publishersversionpublishe
Gel electrophoresis and immunoblotting for the detection of casein proteolysis in cheese
No full textThe whole N fraction of six samples of hard and semi-hard pressed cheeses was analysed using PAGE, polyacrylanzide gel isoelectric focusing and immunoblotting with polyclonal antibodies against beta- and alpha(s1)-casein. The origin of some electrophoretic bands corresponding to peptides produced from the enzymic degradation of the casein fractions was established. A number of these peptides were also present in the in vitro hydrolysates of casein with plasmin and chymosin. Thus, it was also possible to determine which casein was the source of each peptide and which enzymes were active in cheese. Compared with the traditional Coomassie staining procedures, immunoblotting is more sensitive and specific, making the interpretation of each electrophoretic profile easy. Thus, it was also possible to obtain a clear picture of the state of each casein fraction in a cheese variety. Two main peptides were isolated from the pH 4.6-insoluble N fraction of Parmigiano-Reggiano using DEAE-cellulose chromatography and identified, from the amino acid sequence of the N- and C-terminal ends, as gamma(3)-casein ( (beta-casein(f108-209)) and alpha(s1)-PL1 (alpha(s1)-casein(f80-199). In both cases, a Lys-X bond was hydrolysed, indicating the action of a trypsin-like enzyme in beta- and alpha(s1)-casein hydrolysis during the ripening of this variety of hard pressed cheese
Solving the PnP Problem with Anisotropic Orthogonal Procrustes Analysis.
No full textIn this paper we formulate the Perspective-n-Point (a.k.a. exterior orientation) problem in terms of an instance of the anisotropic orthogonal Procrustes problem, and de- rive its solution. Experiments with synthetic and real data demonstrate that our method reaches the best trade-off be- tween speed and accuracy. The MATLAB code reported in the paper testifies that it is also exceedingly simple to im- plement
Image localization and parsing using 3D structure
No full textL'obiettivo di questa tesi è lo studio di due problematiche fondamentali della visione computazionale: la localizzazione direttamente da immagini e la segmentazione semantica di un'immagine.
Il primo contributo di questa tesi è lo sviluppo di un sistema che calcola un'accurata e rapida localizzazione di una fotocamera portatile, utilizzando oltre ad un dataset di immagini pre-registrate, dati tridimensionali ottenuti da una ricostruzione mediante un algoritmo di "Structure from Motion".
L'informazione 3D viene considerata sotto due differenti aspetti: in primo luogo essa è direttamente coinvolta nella fase di registrazione della camera da cui si ottengono robuste corrispondenze di tipo 2D-3D invece di coppie di punti salienti 2D-2D; inoltre il sistema, nella sua fase di reperimento di immagini similari, sfrutta la fase di clusterizzazione dell'algoritmo di "Structure from Motion" migliorando la propria efficienza e robustezza.
La seconda parte della tesi consiste in una analisi dettagliata di uno dei componenti principali del sistema di localizzazione, l'algoritmo di stima della posa della camera partendo da corrispondenze 2D-3D. In particolare viene presentata una nuova formulazione del problema, in letteratura indicato come "Perspective-n-Point problem" o "exterior orientation problem", trasformandola in un'istanza di un problema di analisi di Procrustes di tipo anisotropico ortogonale.
Il contributo finale della tesi è lo sviluppo di un nuovo approccio per la segmentazione semantica di immagini in contesto urbano che coinvolge anch'esso in maniera preponderante la struttura tridimensionale ottenuta dall'algoritmo di "Structure from Motion" in termini di trasferimento di etichette semantiche da un'immagine precedentemente annotata all'immagine di test.
L'immagine da annotare può essere sia un'immagine appartenente al dataset di partenza dell'algoritmo di "Structure from Motion" a cui non è stata associata nessuna informazione semantica, sia un'immagine esterna al dataset che è stata appena registrata mediante il sistema di localizzazione precedentemente descritto.
L'assegnamento delle etichette è modellato mediante un Markov random field i cui nodi sono superpixel estratti dall'immagine di test.The aim of this thesis is the study of two fundamental problems in computer vision: localization from images and semantic image segmentation. The first contribution of this thesis is the development of a complete system that obtains an accurate and fast localization of a hand-held camera device, leveraging not only on a dataset of registered images but also on the three-dimensional information obtained by a Structure from Motion reconstruction.
We exploit the 3D structure under two different aspect: first it is directly involved in the camera registration making available robust 2D-3D correspondences instead of 2D-2D pairs of matched features, furthermore we take advantage of the image clustering computed in the Structure from Motion algorithm during the retrieval step of the localization system improving both robustness and efficiency of the aforementioned algorithmic stage.
The second part of the thesis consists in an in-depth analysis of one of the main components of the localization system, the camera pose estimation from 2D-3D correspondences. In particular we present a novel formulation of the Perspective-n-Point problem, also known as exterior orientation, in terms of an instance of anisotropic orthogonal Procrustes problem.
The last contribution of the thesis is the proposal of a new approach to semantic image segmentation in urban environment that deeply involves the Structure from Motion 3D structure in terms of label transfer from a pre-labeled image to a query image. The query image can be whether an image belonging to the SfM dataset that does not have any semantic information or an external image that has just been localized by the localization system aforementioned. The label assignment problem is modeled as a Markov random field where the nodes are the superpixels of the query image
México en femenino: violencia y cultura según Elena Garro
No full textIn Los Recuerdos del Porvenir, Elena Garro addresses the problematic Mexican sociocultural situation through the female type of the cuscas,or young prostitutes, victims of violence naturalized as an ideological format. This article presents a reading of the novel’s models of literal and symbolic violence through the work of Philippe Bourgois, Pierre Bourdieu, Johan Galtung and Nancy Scheper-Hughes. The representation of these fictional characters in Garro’s novel shows how structural violence permeates social relations through a network of prejudices and systems of oppression that prevent the cuscas’liberation. The characteristics given to the prostitutes in the novel articulate an argument about national identity, which for the author present a potential to define the future. The article concludes by confirming Garro's literature as a committed political activity, due to its critical position in the face of any social discrimination and the revaluation of the sectors neglected by power.Em Los Recuerdos del Porvenir, Elena Garro analisa a problemática situação sociocultural mexicana, através de um tipo feminino específico, as cuscas ou jovens prostitutas, vítimas de violência naturalizadas como formato ideológico.Com base nos textos de Philippe Bourgois, Pierre Bourdieu, Johan Galtung e Nancy Scheper-Hughes, propõe-se uma leitura do modelo de violência literal e simbólica. O tratamento destas personalidades ficcionais mostra como a violencia estrutural permeia as relações sociais através de uma rede de preconceitos e coerções articuladas que impedem a sua libertação. Através das características definidas para o conjunto das prostitutas, pode-se extrapolar uma leitura da identidade nacional, que o autor tem como perspectiva de circunscrever o futuro. Conclui confirmando a literatura de Garro como uma atividade política comprometida, devido à suaposição crítica diante de qualquer discriminação social e da revalorização de setores negligenciados pelo poder.En Los Recuerdos del Porvenir, Elena Garro revisa la problemática situación sociocultural mexicana, mediante un tipo femenino específico, las cuscas o jóvenes prostitutas, víctimas de una violencia naturalizada como formato ideológico.
