La extranjería argentina : una literatura entre la pertenencia y el extrañamiento
No full textDice César Aira que si se hiciera un estudio sistemático de la posición de exilio de los grandes escritores, de cualquier época, los resultados serían sorprendentes. Es probable, de hecho, que terminaran siendo excepciones los que vivieron e hicieron su obra en su patria y su lengua. La extranjería argentina, de Marcos Seifert, parece poner a prueba esta boutade en la lectura de una serie de ficciones contemporáneas que encuentran en los desacoples entre lengua, territorio y cultura un principio inherente a nuestra literatura. Enlazados por la imaginación crítica de Seifert, los relatos de Hebe Uhart, Sergio Chejfec, Clara Obligado, Iosi Havilio, Pía Bouzas, Paloma Vidal, Gabriel Vommaro, Patricio Pron, Pablo Urbanyi, Mariana Dimópulos, Inés Fernández Moreno y Andrés Neuman dibujan el perfil no nacional de la literatura argentina en el presente. De un estilo afable y perspicaz, La extranjería argentina entra y sale y vuelve a entrar a estos relatos con gracia sostenida. El libro compone el capítulo reciente de esa “tradición de la extranjería”, con raíces en el siglo xix, que fundamenta todos los argumentos de Marcos Seifert.

Rational Seifert Surfaces in Seifert Filtered Spaces
No full textRationally null-homologous links in Seifert fibered spaces may be represented combinatorially via labeled diagrams. We introduce an additional condition on a labeled link diagram and prove that it is equivalent to the existence of a rational Seifert surface for the link. In the case when this condition is satisfied, we generalize Seifert\u27s algorithm to explicitly construct a rational Seifert surface for any rationally null-homologous link. As an application of the techniques developed in the paper, we derive closed formulae for the rational Thurston-Bennequin and rotation numbers of a rationally null-homologous Legendrian knot in a contact Seifert fibered space. --author-supplied descriptio
La regla y la vida: formas de vida en común en "Cómo vivir juntos" de Roland Barthes y "Altísima pobreza" de Giorgio Agamben
No full textEl motivo de la aproximación de estos dos estudios distantes cronológicamente no se sostiene simplemente en la apuesta a un diálogo sostenido en la mera atención en el monaquismo, sino también, y sobre todo, en el afán compartido por indagar una particular relación entre la regla y la vida. Si bien la concepción y lasimplicancias de la idea de regla difieren en cada caso, hay un interés mutuo en pensar la articulación entre la regla y la vida desde una dimensión ética que cuestiona los modos de entender los vínculos entre costumbres, leyes y vida. Ya sea que los modos de habitar den pie a pensar una forma de vida o un imaginario como práctica, el acento en ambos casos está puesto en una redefinición ética a partir de la que podemos interrogarnos acerca de la cercanía entre la propuesta del "uso" que hace Agamben con el planteo barthesiano del "no querer asir".Fil: Seifert, Marcos Germán.

Los poderes de la fantasía
No full textEstudiar un género literario —la fantasía científica— en relación con los avatares de la institucionalización de la ciencia y con los procesos de modernización en la Argentina permite a Sandra Gasparini una redefinición del corpus canónico de la literatura argentina del siglo XIX. Gasparini rescata y recoloca, en una red intertextual de visibilidad y relevancia, una serie de textos postergados por no pertenecer al grupo de obras recurrentes en las antologías o por no ser del gusto de una crítica que suele preferir la literatura fantástica o de ciencia ficción. Esta textualidad heterogénea, que como señala la autora se sitúa en el borde de los géneros y los saberes y es el lugar de su intersección, queda fuera de una tendencia a concentrar el análisis literario en una lista de libros representativos, autorizados y reconocidos. Consciente de esta intervención sobre la cuestión canónica, Gasparini esquiva con inteligencia la noción de precursor, que implicaría colocar el abordaje crítico en el lugar del descubrimiento de aquellos que incurrieron en estrategias y temáticas luego perfeccionadas por autores del canon. Gasparini amplía los límites del corpus jerárquico según la convicción de Harold Bloom de que “toda poderosa originalidad literaria se convierte en canónica”Fil: Seifert, Marcos Germán.

Sueños y realidades góticas: excesos y espectros del terror rosista en algunos relatos de Juana Manuela Gorriti
No full textLa insistencia de ciertos relatos de Juana Manuela Gorriti en volver al período histórico dominado políticamente por la figura de Juan Manuel de Rosas converge en algunos casos con una inclinación a incorporar elementos de la tradición literaria gótica. Para representar los excesos de la política, la autora apela a los recursos de una estética también excesiva. Indagaremos la particularidad de esta articulación en la que el gótico puede entenderse como matriz que permite dar cuenta de identidades y prácticas vinculadas a lo político y lo social. Para ello nos concentraremos en las implicaciones de la juntura entre gótico y política en los relatos “El Lucero del Manantial”, “El guante negro” y “La hija del mashorquero” publicados en Sueños y realidades de 1865. En el primero focalizaremos el modo en que la ficción gótica toma sentido en relación con la incorporación del material histórico. En los otros dos relatos nos concentraremos fundamentalmente en la conjugación del gótico con otra forma genérica también atravesada por el exceso: el melodrama.The insistence of certain stories of Juana Manuela Gorriti in returning to a historical period politically dominated by the figure of Juan Manuel de Rosas converges in some cases with a tendency to incorporate elements of the Gothic literary tradition. To represent the excesses of politics, the author appeals to the resources of an excessive aesthetics. We explore the peculiarity of this articulation where the Gothic can be understood as a matrix that allows to account for identities and practices related to political and social issues. To do this the author focuses on the implications of the articulation between the Gothic and politics in the stories " El Lucero del Manantial", “El guante negro" and "La hija del mashorquero" published in Sueños y Realidades in 1865. In the first example the focus is on how Gothic fiction acquires sense when incorporating historical material. In the other two stories we deal primarily with the combination of Gothic with another genre also marked by excess: melodrama.Fil: Seifert, Marcos Germán. Universidad de Buenos Aires; Argentina.

An algorithm to calculate generalized Seifert matrices
No full textFriedl S, Kausik C, Qintanilha JP. An algorithm to calculate generalized Seifert matrices. Journal of Knot Theory and Its Ramifications. 2022.We develop an algorithm for computing generalized Seifert matrices for colored links given as closures of colored braids. The algorithm has been implemented by the second author as a computer program called Clasper. Clasper also outputs the Conway potential function, the multivariable Alexander polynomial, the Cimasoni-Florens signatures and the nullities of a link, and displays a visualization of the C-complex used for producing the generalized Seifert matrices

Eyes relatively small, EYE 0.234. Frontal carinae immediately caudal of the FRS level parallel or very slightly converging. Foveolae on vertex without interspaces, deeply impressed, with 13 – 19 µm diameter, and with an inner corona (a flat tubercle) of 7 – 9 µm diameter having the base of a decumbent pubescence hair in its center. This type of sculpture can also be described as a strongly sculptured microreticulum. Longitudinal sculpture on vertex often completely absent (Fig. 15). Weak semicircular rugae are found around the antennal fossae. Lateral mesosoma on whole surface regularly and strongly microreticulate-foveolate; longitudinal sculpture except for 4 – 6 weak and short carinulae on metapleuron completely absent (Fig. 16); dorsal mesosoma irregularly reticulate-foveolate-shagrinate. Sides of petiole with a deeply sculptured microreticulum, dorsal petiole and postpetiole with a weak and shallowly sculptured microreticulum. Cuticular surface of first gaster tergite rather smooth and shining but on its whole surface with a well-developed microreticulum (Fig. 14). The pubescence hairs on gaster tergites are the shortest within the C. nuda group, PLG/CS is only 5.06%. Metanotal depression very shallow, MGr/CS 1.28%. Propodeal spines short but clearly longer than in the C. mauritanica species complex. Dorsal propodeum sloping down to base of spines under an angle of 20°. Petiole node slightly longer than wide. Postpetiole in dorsal view with only suggestedly angulate sides and straight anterior margin that is slightly shorter than posterior margin; postpetiolar sternite bulging, without any protrusions but on each side with a suggested paramedian, longitudinal carina. Head, mesosoma, waist and appendages often amber-colored, gaster significantly darker—this is the most frequently observed coloration but populations with dark headed specimens or such with concolorous amber specimens do occur. For morphometric data of 52 workers see Tab. 2. Geographic range. Australia, only species of the whole genus Cardiocondyla occurring in inner Australia. Diagnosis. see key. The very short gastral pubescence is the most obvious difference to the sister species C. atalanta. Biology. C. paranuda is apparently well adapted to arid and very hot climate and the only species of the whole genus Cardiocondyla occurring in inner Australia. This is demonstrated by significant differences between C. atalanta and C.paranuda in the continentality of the sites. The mean distance from sea shore and mean annual rainfall are 23 ± 51 [0,252] km and 1430 ± 716 [500, 4500] mm in 27 sites of C. atalanta and 329 ± 332 [0, 904] km and 588 ± 385 [150, 1250] mm in 27 sites of C. paranuda. These differences are significantly different in both sea shore distance (ANOVA F1,52=22.39, p<0.0005) and annual rainfall (ANOVA F1,52=28.90, p<0.0005). As yet only foragers have been collected and colony structure, male morphology, and behavior are unknown. Comments. There is a serious problem with the site documentation in the holotype of C. paranuda. The specimen was sent by C.A. Collingwood to the senior author in the 1980s with the labelling " TUNISIA: Medinine- 32 km SE Chabania- 6 km NW leg. H.Heatwole 1976 “. If run as a wild-card in a LDA considering all 16 morphometric characters and collecting all samples of the C. mauritanica species complex in class 1 and all of the C. nuda complex in class 2, the holotype C. paranuda is allocated to the C. nuda complex with p=1.0000. This is problematic because species of the C. nuda species complex are completely absent from the West Palaearctic and North Africa and it appears also most unlikely that ants from Australia should have been anthropogenically introduced to a site in the Sahara desert. Furthermore, NC-clustering places the holotype in a cluster of C. nuda group specimens that are treated as a single species that is restricted to the Australian continent and sister to C. atalanta (Fig. 8). A wild-card run in a LDA confirms this allocation with p=0.9916 (see section 4.4). The most probable explanation for this conflicting situation is a confusion of labels. Harold Heatwole collected in North Africa, Tibet and Australia—for instance, the two C. paranuda samples from Queensland: Chilcott Island in 1967 were taken by him. He usually gave his specimens to Collingwood stored in tubes with ethanol. As repeatedly witnessed by the senior author in personal contacts during laboratory work in 1982 and 1990, Collingwood had the dangerous habit of placing similar ethanol-stored ants from different tubes side-by-side under the microscope for better comparison and sometimes he confused from which tube he had taken the specimens. We conclude that the type of C. paranuda has most probably been collected somewhere in Australia.Published as part of Seifert, Bernhard, Okita, Ichiro & Heinze, Jürgen, 2017, A taxonomic revision of the Cardiocondyla nuda group (Hymenoptera: Formicidae), pp. 324-356 in Zootaxa 4290 (2) on pages 346-349, DOI: 10.11646/zootaxa.4290.2.4, http://zenodo.org/record/82907
El animal extranjero: <i>Silver</i> de Pablo Urbanyi
No full textEl propósito del siguiente trabajo es abordar el personaje de Silver, que le da nombre a la novela de Pablo Urbanyi, como una figura de extranjería que desestabiliza categorías políticas y jurídicas por su posición de doble exterioridad. Como animal en su devenir humano exhibe la cesura entre el hombre y animal como una división jerárquica que legitima otras dominaciones entre los hombres. Como desplazado inserto en la cultura norteamericana deja en evidencia la lógica de espectáculo y de cálculo económico que rigen tanto la labor académica como la idea de una diversidad cultural forjada en el marco de una cultura global que somete al otro a una identidad prefijada. La mirada extranjera de Silver se sostiene en una forma de participación sin identificación mediante la cual el personaje ejerce una resistencia a las lógicas de imposición identitaria de los espacios representados en la novela.The purpose of this paper is to tackle the character of Silver, the animal that gives its name to Pablo Urbanyi’s novel, as a figure of foreignness that destabilizes political and legal categories due to its position of double externality. As an animal becoming a human, Silver exhibits the break between man and animal as a hierarchical division that legitimizes other dominations among men. As a displaced figure placed in American culture, Silver clearly shows the logic of spectacle and purely economic interests that govern both academic work and the idea of cultural diversity forged in the context of a global culture that subjects the other to a predetermined identity. Silver’s foreign insight is grounded in a form of participation without identification whereby the character presents a resistance to the logic of identity imposition on the spaces represented in the novel.Fil: Seifert, Marcos Germán.

Analysing Author Self-citations in Computer Science Publications
No full textIn scientific papers, citations refer to relevant previous work in order to underline the current line of argumentation, compare to other work and/or avoid repetition in writing. Self-citations, e.g. authors citing own previous work might have the same motivation but have also gained negative attention w.r.t. unjustified improvement of scientific performance indicators. Previous studies on self-citations do not provide a detailed analysis in the domain of computer science. In this work, we analyse the prevalence of self-citations in the DBLP, a digital library for computer science. We find, that approx. 10% of all citations are self-citations, while the rates vary with year after publication and the position of the author in the list as well as with the gender of the lead author. Further, we find that C-ranked venues have the highest incoming self-citation rate, while the outgoing rate is stable across all ranks
