"Ella", de Juan Carlos Onetti. Necrofilia y ficción (Homenaje)

La autora reflexiona sobre el relato “Ella”, del uruguayo Juan Carlos Onetti, y sobre otras representaciones de la muerte de Eva Perón, escritas por Jorge Luis Borges, David Viñas y Néstor Perlongher. Afirma que en la Argentina de Perón ya confluían realidad y ficción, y que las múltiples biografías de Eva serían “un duelo de versiones narrativas entre la ficción y la historia o, si se prefiere, una metáfora de la historia”. Rosano plantea que, en los textos revisados, es la realidad la que adopta contornos fantasmagóricos, disparados por motivos diversos: la descomposición y el tópico del mal olor, la impostura del cuerpo embalsamado y del mandatario, el entrelazamiento entre lo político y lo sexual en la escena del velorio, la imagen de Eva, “una diosa que muestra sus encajes de novia de suburbio” pero también una siniestra y doliente “zombi escarlata”. Señala, finalmente, que los textos muestran a los fieles, esos “miles de necrófilos murmurantes y enlutados”, sometidos a la potencia del mito.

Tyche

The word tyche (plural tychai) denotes an ancient Greek concept encompassing many aspects of fortune – chance, fate, luck, occurrence, even achievement, success, and wealth – both good and bad. As a personification of that concept, the goddess Tyche came to symbolize the fate and fortune of rulers and through them their cities; she thus emerged as the preeminent city goddess throughout the Hellenistic and Roman worlds. Her name is etymologically related to the verb tynchanein (“to hit, meet with, be favored with, happen accidentally”). The connection between the noun and verb is so close that it is difficult to distinguish in Greek literature between the deity and the abstraction.

Os herdeiros de Ananse: movimento negro, ações afirmativas, cotas para negros na universidade

Ananse, a metamorfose em aranha da deusa Aranã, procedente da cultura fanthi-ashanti, da região do Benin na África ocidental, configura-se, neste trabalho na metáfora símbolo das ações de resistência empreendidas pelos africanos seus descendentes no continente americano, particularmente no, Brasil. Dessa maneira, apresenta um relato etnográfico da saga dos herdeiros da deusa Aranã em luta contra o racismo. A estrutura desta narrativa é a de um Auto Teatral em que o personagem antagonista é o Racismo e o protagonista são os herdeiros de Ananse. A composição dessa narrativa parte da premissa de que as diversas culturas trazidas pelo protagonista exerceram importância fundamental, para alimentar a luta dos africanos e seus herdeiros, frente à astúcia de um antagonista capaz de se travestir, no tempo e no espaço, de várias personas (máscaras) para desorientar e enfraquecer os discursos do protagonista. Entretanto, o protagonista também é astucioso na elaboração de suas teias. No tecido desta narrativa recupero as teias elaboradas por este personagem para inserir na agenda do estado brasileiro o reconhecimento da existência do racismo e da discriminação racial, na sociedade. e as políticas públicas de ação afirmativa, em especial, o emprego do sistema de cotas para negros na universidade. O embate é uma narrativa com características épicas que privilegia o papel do fio/ação movimento negro.

Conflito, resistência e philía no Héracles furioso de Eurípides

In Heracles Mainomenos, by Euripides, the hero is submited to the ultimate test: win himself, accepting stay alive after committing an irremediable error. The dramatic action has dual motivation, human and divine. The human conflict requires resilience of families and friends of Heracles and the opposition of Lico is a key element to the action. In the subsequent clash between Heracles and the goddess Hera, victory lies with the deity, motivating the disaster, but confirms the heroics of Heracles, that resists the urge to annihilation after the murder of children. His friend, King Theseus, provides him the support needed to dissuade him from his purpose of annihilation and strengthens him for endurance. The valuation of philia is an important element in shaping the sense of this euripidean text.

La figure de Méduse. Réécritures ovidiennes entre XVIe et XVIIe siècle

Starting from an original assumption that Ovid is one of the most influential and studied European mythographers from ancient times till at least the end of the XVII century, my research is about rediscovering Medusa's myth which has been brought to us from Metamorphosis during the period of time between the mid XVI and the last years of the XVII century. The main thread that leads the research trough English, French, Spanish and Italian Literatures gets particularly clarified in the crucial crux that binds the image of Gorgon, the protector of hight mysteries, tightly correlated to the goddess of knowledge, Minerva, and the attraction/dismay for knowing so far considered inaccessible but now perceived as possible (so more attractive than before) thanks to the scientific and geographic discoveries of the Renaissance.

Gravitational slopes, geomorphology, and material strengths of the nucleus of comet 67P/Churyumov-Gerasimenko from OSIRIS observations

Aims. We study the link between gravitational slopes and the surface morphology on the nucleus of comet 67P/Churyumov-Gerasimenko and provide constraints on the mechanical properties of the cometary material (tensile, shear, and compressive strengths). Methods. We computed the gravitational slopes for five regions on the nucleus that are representative of the different morphologies observed on the surface (Imhotep, Ash, Seth, Hathor, and Agilkia), using two shape models computed from OSIRIS images by the stereo-photoclinometry (SPC) and stereo-photogrammetry (SPG) techniques. We estimated the tensile, shear, and compressive strengths using different surface morphologies (overhangs, collapsed structures, boulders, cliffs, and Philae's footprint) and mechanical considerations. Results. The different regions show a similar general pattern in terms of the relation between gravitational slopes and terrain morphology: i) low-slope terrains (0-20 degrees) are covered by a fine material and contain a few large (>10 m) and isolated boulders; ii) intermediate-slope terrains (20-45 degrees) are mainly fallen consolidated materials and debris fields, with numerous intermediate-size boulders from <1m to 10m for the majority of them; and iii) high-slope terrains (45-90 degrees) are cliffs that expose a consolidated material and do not show boulders or fine materials. The best range for the tensile strength of overhangs is 3-15 Pa (upper limit of 150 Pa), 4-30 Pa for the shear strength of fine surface materials and boulders, and 30-150 Pa for the compressive strength of overhangs (upper limit of 1500 Pa). The strength-to-gravity ratio is similar for 67P and weak rocks on Earth. As a result of the low compressive strength, the interior of the nucleus may have been compressed sufficiently to initiate diagenesis, which could have contributed to the formation of layers. Our value for the tensile strength is comparable to that of dust aggregates formed by gravitational instability and tends to favor a formation of comets by the accrection of pebbles at low velocities.

Insolation, erosion, and morphology of comet 67P/Churyumov-Gerasimenko

Context. The complex shape of comet 67P and its oblique rotation axis cause pronounced seasonal effects. Irradiation and hence activity vary strongly. Aims. We investigate the insolation of the cometary surface in order to predict the sublimation of water ice. The strongly varying erosion levels are correlated with the topography and morphology of the present cometary surface and its evolution. Methods. The insolation as a function of heliocentric distance and diurnal (spin dependent) variation is calculated using >10(5) facets of a detailed digital terrain model. Shading, but also illumination and thermal radiation by facets in the field of view of a specific facet are iteratively taken into account. We use a two-layer model of a thin porous dust cover above an icy surface to calculate the water sublimation, presuming steady state and a uniform surface. Our second model, which includes the history of warming and cooling due to thermal inertia, is restricted to a much simpler shape model but allows us to test various distributions of active areas. Results. Sublimation from a dirty ice surface yields maximum erosion. A thin dust cover of 50 pm yields similar rates at perihelion. Only about 6% of the surface needs to be active to match the observed water production rates at perihelion. A dust layer of 1 mm thickness suppresses the activity by a factor of 4 to 5. Erosion on the south side can reach more than 10 m per orbit at active spots. The energy input to the concave neck area (Hapi) during northern summer is enhanced by about 50% owing to self-illumination. Here surface temperatures reach maximum values along the foot of the Hathor wall. Integrated over the whole orbit this area receives the least energy input. Based on the detailed shape model, the simulations identify "hot spots" in depressions and larger pits in good correlation with observed dust activity. Three-quarters of the total sublimation is produced while the sub-solar latitude is south, resulting in a distinct dichotomy in activity and morphology. Conclusions. The northern areas display a much rougher morphology than what is seen on Imhotep, an area at the equator that will be fully illuminated when 67P is closer to the Sun. Self-illumination in concave regions enhance the energy input and hence erosion. This explains the early activity observed at Hapi. Cliffs are more prone to erosion than horizontal, often dust covered, areas, which leads to surface planation. Local activity can only persist if the forming cliff walls are eroding. Comet 67P has two lobes and also two distinct sides. Transport of material from the south to the north is probable. The morphology of the Imhotep plain should be typical for the terrains of the yet unseen southern hemisphere.

Large-scale dust jets in the coma of 67P/Churyumov-Gerasimenko as seen by the OSIRIS instrument onboard Rosetta

Context. During the most recent perihelion passage in 2009 of comet 67P/Churyumov-Gerasimenko (67P), ground-based observations showed an anisotropic dust coma where jet-like features were detected at similar to 1.3 AU from the Sun. The current perihelion passage is exceptional as the Rosetta spacecraft is monitoring the nucleus activity since March 2014, when a clear dust coma was already surrounding the nucleus at 4.3 AU from the Sun. Subsequently, the OSIRIS camera also witnessed an outburst in activity between April 27 and 30, and since mid-July, the dust coma at rh similar to 3.7-3.6 AU preperihelion is clearly non-isotropic, pointing to the existence of dust jet-like features. Aims. We aim to ascertain on the nucleus surface the origin of the dust jet-like features detected as early as in mid-July 2014. This will help to establish how the localized comet nucleus activity compares with that seen in previous apparitions and will also help following its evolution as the comet approaches its perihelion, at which phase most of the jets were detected from ground-based observations. Determining these areas also allows locating them in regions on the nucleus with spectroscopic or geomorphological distinct characteristics. Methods. Three series of dust images of comet 67P obtained with the Wide Angle Camera (WAC) of the OSIRIS instrument onboard the Rosetta spacecraft were processed with different enhancement techniques. This was made to clearly show the existence of jet-like features in the dust coma, whose appearance toward the observer changed as a result of the rotation of the comet nucleus and of the changing observing geometry from the spacecraft. The position angles of these features in the coma together with information on the observing geometry, nucleus shape, and rotation, allowed us to determine the most likely locations on the nucleus surface where the jets originate from. Results. Geometrical tracing of jet sources indicates that the activity of the nucleus of 67P gave rise during July and August 2014 to large-scale jet-like features from the Hapi, Hathor, Anuket, and Aten regions, confirming that active regions may be present on the nucleus localized at 60. northern latitude as deduced from previous comet apparitions. There are also hints that large-scale jets observed from the ground are possibly composed, at their place of origin on the nucleus surface, of numerous small-scale features.

Size-frequency distribution of boulders ≥7 m on comet 67P/Churyumov-Gerasimenko

Aims. We derive for the first time the size-frequency distribution of boulders on a comet, 67P/Churyumov-Gerasimenko (67P), computed from the images taken by the Rosetta/OSIRIS imaging system. We highlight the possible physical processes that lead to these boulder size distributions. Methods. We used images acquired by the OSIRIS Narrow Angle Camera, NAC, on 5 and 6 August 2014. The scale of these images (2.44−2.03 m/px) is such that boulders ≥7 m can be identified and manually extracted from the datasets with the software ArcGIS. We derived both global and localized size-frequency distributions. The three-pixel sampling detection, coupled with the favorable shadowing of the surface (observation phase angle ranging from 48° to 53°), enables unequivocally detecting boulders scattered all over the illuminated side of 67P. Results. We identify 3546 boulders larger than 7 m on the imaged surface (36.4 km2), with a global number density of nearly 100/km2 and a cumulative size-frequency distribution represented by a power-law with index of −3.6 +0.2/−0.3. The two lobes of 67P appear to have slightly different distributions, with an index of −3.5 +0.2/−0.3 for the main lobe (body) and −4.0 +0.3/−0.2 for the small lobe (head). The steeper distribution of the small lobe might be due to a more pervasive fracturing. The difference of the distribution for the connecting region (neck) is much more significant, with an index value of −2.2 +0.2/−0.2. We propose that the boulder field located in the neck area is the result of blocks falling from the contiguous Hathor cliff. The lower slope of the size-frequency distribution we see today in the neck area might be due to the concurrent processes acting on the smallest boulders, such as i) disintegration or fragmentation and vanishing through sublimation; ii) uplifting by gas drag and consequent redistribution; and iii) burial beneath a debris blanket. We also derived the cumulative size-frequency distribution per km2 of localized areas on 67P. By comparing the cumulative size-frequency distributions of similar geomorphological settings, we derived similar power-law index values. This suggests that despite the selected locations on different and often opposite sides of the comet, similar sublimation or activity processes, pit formation or collapses, as well as thermal stresses or fracturing events occurred on multiple areas of the comet, shaping its surface into the appearance we see today.

Rescatando del Leteo crítico a Juan Crisóstomo Lafinur

A menudo la diosa Crítica argentina se empecina en sumergir en el río del olvido a no pocas figuras literarias de nuestro país del siglo XIX. Se podrían ofrecer como excusas, en algunos casos, el despótico paso del tiempo (mientras más nos alejamos del presente más difícil es indagar sobre talo cual autor); en otros, la escasa información biográfica; o la condición paupérrima de ciertas ediciones; o el estado a veces inabarcable de hombresorquesta de estos individuos (son poetas, guerreros, filósofos, etc. y esto sin descuidar ninguno de sus oficios), y así seguiríamos enumerando hasta el hartazgo. Pero así como existe una tendencia a lograr una moderna historiografia argentina de la mano de estudiosos como Tulio Halperin Donghi, revisando los hechos a la luz de sus desencadenantes ideológicos, también se debería proponer un buceo histórico-literario para sacar a la luz varias perlas literarias, engarzadas en sus correspondientes ideologías. Este trabajo se propone ser la ayuda virgiliana que rescate del olvido a Juan Crisóstomo Lafinur, sobre todo su labor poética, ya que de la filosófica todos sabemos de su importante trascendencia. Para esta última sólo tenemos que recordar las palabras de Roberto F. Giusti: "La historia de la evolución mental argentina quedaría incompleta si en ella no hiciésemos un lugar a Lafinur".

Conflito, resistência e philía no Héracles furioso, de Eurípides

En la pieza Heracles Furioso, de Eurípides, el héroe se somete a la prueba definitiva: vencerse a sí mismo, aceptar seguir con vida después de cometer un error irremediable. La acción dramática tiene doble motivación, humana y divina. El conflicto humano requiere capacidad de resistencia de la familia y amigos de Heracles y la oposición de Lico es un elemento clave para la acción. En el enfrentamiento posterior entre Heracles y la diosa Hera, la victoria corresponde a la deidad, motivando a la catástrofe, pero se confirma la heroicidad de Heracles, que se resiste a la tentación de aniquilación tras el asesinato de sus niños. Su amigo, el rey Teseo, le proporciona el apoyo necesario para disuadirle de su propósito de aniquilamiento y fortalece al héroe decaído para la resistencia. La valoración de philia es un elemento importante en la constitución de la significación del texto de Eurípides
