Breaking Images, Widening Perceptions : Reflections on Horacio Quiroga in Translation

Horacio Quiroga (1878-1937) es uno de los escritores más logrados por sus cuentos y sigue siendo aclamado por la crítica en el mundo de habla hispana. Sus obras son consideradas parte del canon dentro de la tradición literaria sudamericana. Algunas de sus historias más renombradas circulan para la audiencia más global, publicadas en diversas colecciones y antologías que han sido posibles por haber sido traducidas al inglés. La versión más disponible en inglés es la traducción realizada por Margaret Sayers Peden ((1976) 2004), Quiroga habla por medio de las elecciones que realizó la traductora. Sin embargo, cabe preguntarse: ¿es este el Horacio Quiroga que las generaciones anteriores conocieron, apreciaron y alabaron? ¿Han logrado sobrevivir a la operación traductológica en inglés su prosa exquisita y su narrativa fotográfica para los lectores en inglés? Este artículo intenta abordar temas centrales de la traducción literaria en cuanto los textos de Quiroga y de Sayers Peden. También trata sobre las estrategias de domesticación, sobre cómo la manipulación del original puede traer consecuencias para la legibilidad, además la importancia de conocer bien los rasgos sociopolíticos y las características geográficas y, no menor, la responsabilidad profesional implícita en el rol del traductor como mediador cultural ya que selecciona, edita y publica literatura que no pertenece a lo convencional y establecido.

Conformational states of HIV-1 reverse transcriptase for nucleotide incorporation vs. pyrophosphorolysis – binding of foscarnet

HIV-1 reverse transcriptase (RT) catalytically incorporates individual nucleotides into a viral DNA strand complementing an RNA or DNA template strand; the polymerase active site of RT adopts multiple conformational and structural states while performing this task. The states associated are dNTP binding at the N site, catalytic incorporation of a nucleotide, release of a pyrophosphate, and translocation of the primer 3′-end to the P site. Structural characterization of each of these states may help in understanding the molecular mechanisms of drug activity and resistance and in developing new RT inhibitors. Using a 38-mer DNA template-primer aptamer as the substrate mimic, we crystallized an RT/dsDNA complex that is catalytically active, yet translocation-incompetent in crystals. The ability of RT to perform dNTP binding and incorporation in crystals permitted obtaining a series of structures: (I) RT/DNA (P-site), (II) RT/DNA/AZTTP ternary, (III) RT/AZT-terminated DNA (N-site), and (IV) RT/AZT-terminated DNA (N-site)/foscarnet complexes. The stable N-site complex permitted the binding of foscarnet as a pyrophosphate mimic. The Mg2+ ions dissociated after catalytic addition of AZTMP in the pretranslocated structure III, whereas ions A and B had re-entered the active site to bind foscarnet in structure IV. The binding of foscarnet involves chelation with the Mg2+ (B) ion and interactions with K65 and R72. The analysis of interactions of foscarnet and the recently discovered nucleotide-competing RT inhibitor (NcRTI) α-T-CNP in two different conformational states of the enzyme provides insights for developing new classes of polymerase active site RT inhibitors.

Isolating the photovoltaic junction: atomic layer deposited TiO2-RuO2 alloy Schottky contacts for silicon photoanodes

We synthesized nanoscale TiO2-RuO2 alloys by atomic layer deposition (ALD) that possess a high work function and are highly conductive. As such, they function as good Schottky contacts to extract photogenerated holes from n-type silicon while simultaneously interfacing with water oxidation catalysts. The ratio of TiO2 to RuO2 can be precisely controlled by the number of ALD cycles for each precursor. Increasing the composition above 16% Ru sets the electronic conductivity and the metal work function. No significant Ohmic loss for hole transport is measured as film thickness increases from 3 to 45 nm for alloy compositions >= 16% Ru. Silicon photoanodes with a 2 nm SiO2 layer that are coated by these alloy Schottky contacts having compositions in the range of 13-46% Ru exhibit average photovoltages of 525 mV, with a maximum photovoltage of 570 mV achieved. Depositing TiO2-RuO2 alloys on nSi sets a high effective work function for the Schottky junction with the semiconductor substrate, thus generating a large photovoltage that is isolated from the properties of an overlying oxygen evolution catalyst or protection layer.

Environmental factors correlated with the metabolite profile of Vitis vinifera cv. Pinot Noir berry skins along a European latitudinal gradient

Mature berries of Pinot Noir grapevines were sampled across a latitudinal gradient in Europe, from southern Spain to central Germany. Our aim was to study the influence of latitude-dependent environmental factors on the metabolite composition (mainly phenolic compounds) of berry skins. Solar radiation variables were positively correlated with flavonols and flavanonols and, to a lesser extent, with stilbenes and cinnamic acids. The daily means of global and erythematic UV solar radiation over long periods (bud break-veraison, bud break-harvest, and veraison-harvest), and the doses and daily means in shorter development periods (5–10 days before veraison and harvest) were the variables best correlated with the phenolic profile. The ratio between trihydroxylated and monohydroxylated flavonols, which was positively correlated with antioxidant capacity, was the berry skin variable best correlated with those radiation variables. Total flavanols and total anthocyanins did not show any correlation with radiation variables. Air temperature, degree days, rainfall, and aridity indices showed fewer correlations with metabolite contents than radiation. Moreover, the latter correlations were restricted to the period veraison-harvest, where radiation, temperature, and water availability variables were correlated, making it difficult to separate the possible individual effects of each type of variable. The data show that managing environmental factors, in particular global and UV radiation, through cultural practices during specific development periods, can be useful to promote the synthesis of valuable nutraceuticals and metabolites that influence wine quality.

Exploring the scope of asymmetric synthesis of β-Hydroxy-γ-lactams via Noyori-type reductions

Enantio- and diastereoselective hydrogenation of β-keto-γ-lactams with a ruthenium–BINAP catalyst, involving dynamic kinetic resolution, has been employed to provide a general, asymmetric approach to β-hydroxy-γ-lactams, a structural motif common to several bioactive compounds. Full conversion to the desired β-hydroxy-γ-lactams was achieved with high diastereoselectivity (up to >98% de) by addition of catalytic HCl and LiCl, while β-branching of the ketone substituent demonstrated a pronounced effect on the modest to excellent enantioselectivity (up to 97% ee) obtained.

Engineering interfacial silicon dioxide for improved metal-insulator-semiconductor silicon photoanode water splitting performance

Silicon photoanodes protected by atomic layer deposited (ALD) TiO2 show promise as components of water splitting devices that may enable the large-scale production of solar fuels and chemicals. Minimizing the resistance of the oxide corrosion protection layer is essential for fabricating efficient devices with good fill factor. Recent literature reports have shown that the interfacial SiO2 layer, interposed between the protective ALD-TiO2 and the Si anode, acts as a tunnel oxide that limits hole conduction from the photoabsorbing substrate to the surface oxygen evolution catalyst. Herein, we report a significant reduction of bilayer resistance, achieved by forming stable, ultrathin (<1.3 nm) SiO2 layers, allowing fabrication of water splitting photoanodes with hole conductances near the maximum achievable with the given catalyst and Si substrate. Three methods for controlling the SiO2 interlayer thickness on the Si(100) surface for ALD-TiO2 protected anodes were employed: (1) TiO2 deposition directly on an HF-etched Si(100) surface, (2) TiO2 deposition after SiO2 atomic layer deposition on an HF-etched Si(100) surface, and (3) oxygen scavenging, post-TiO2 deposition to decompose the SiO2 layer using a Ti overlayer. Each of these methods provides a progressively superior means of reliably thinning the interfacial SiO2 layer, enabling the fabrication of efficient and stable water oxidation silicon anodes.

Self-healing thermal annealing: surface morphological restructuring control of GaN nanorods

With advances in nanolithography and dry etching, top-down methods of nanostructuring have become a widely used tool for improving the efficiency of optoelectronics. These nano dimensions can offer various benefits to the device performance in terms of light extraction and efficiency, but often at the expense of emission color quality. Broadening of the target emission peak and unwanted yellow luminescence are characteristic defect-related effects due to the ion beam etching damage, particularly for III–N based materials. In this article we focus on GaN based nanorods, showing that through thermal annealing the surface roughness and deformities of the crystal structure can be “self-healed”. Correlative electron microscopy and atomic force microscopy show the change from spherical nanorods to faceted hexagonal structures, revealing the temperature-dependent surface morphology faceting evolution. The faceted nanorods were shown to be strain- and defect-free by cathodoluminescence hyperspectral imaging, micro-Raman, and transmission electron microscopy (TEM). In-situ TEM thermal annealing experiments allowed for real time observation of dislocation movements and surface restructuring observed in ex-situ annealing TEM sampling. This thermal annealing investigation gives new insight into the redistribution path of GaN material and dislocation movement post growth, allowing for improved understanding and in turn advances in optoelectronic device processing of compound semiconductors.

Is There a New Bibliography?

Describes the position claiming that the contemporary technologi- cal, sociopolitical, and socioeconomic environment gives us pause to consider the core theory and practices of bibliography, combin- ing bibliography of the work (in library and information science), bibliography of the text (in textual studies and scholarly editing), and bibliography of the artifact (in book history and now digital forensics), and calls for collaborative multidisciplinary research at the intersection of these fields to ask, is there a new bibliography?

Tendencia editorial UR Número 3

El Boletín Tendencia Editorial es un proyecto que nació en 2010 con motivo de la Feria Internacional del Libro de Bogotá para construir y hacer visibles diferentes saberes desde la academia y la edición. Para 2014, el cambio de periodicidad coincidió con uno de los eventos más importantes para la edición universitaria, la Feria Internacional del Libro de Guadalajara donde anualmente se realiza el encuentro de Editores Universitarios Latinoamericanos, el proyecto pasó de su fase nacional a ser pensado en red. Las líneas temáticas traspasan fronteras locales y convocan, en un mismo espacio, las voces de los gestores y especialistas, cuya labor y experiencia permiten cada día mejorar la edición universitaria, lo que posibilita acabar con el mito que concibe a la Universidad como ente ajeno a la sociedad, cuando en realidad esta es la forjadora de líderes, investigadores y emprendedores.

La construcción de sentido (‘sensemaking’) de un entorno estratégico turbulento por parte de los altos directivos: un estudio en una multinacional automotriz

Este artículo presenta los resultados de una investigación realizada al interior de dos contextos. Por un lado, el teórico, en el marco de uno de los discursos más relevantes en los campos de la estrategia organizacional, de la managerial and organizational cognition (MOC) y, en general, de los estudios organizacionales (organization studies): la construcción de sentido (sensemaking). Por el otro, el empírico, en una de las grandes compañías multinacionales del sector automotriz con presencia global. Esta corporación enfrenta una permanente tensión entre lo que dicta la casa matriz, en relación con el cumplimiento de metas y estándares específicos, considerando el mundo entero, y los retos que, teniendo en cuenta lo regional y lo local, experimentan los altos directivos encargados de hacer prosperar la empresa en estos lugares. La aproximación implementada fue cualitativa. Esto en atención a la naturaleza de la problemática abordada y la tradición del campo. Los resultados permiten ampliar el actual nivel de comprensión acerca de los procesos de sensemaking de los altos directivos al enfrentar un entorno estratégico turbulento.

Caminhos da crítica textual Da filologia à interdisciplinaridade: o caso das edições dos Sermões de Padre António Vieira

The present paper discusses the problem of the plurality of the text, as a cultural object, and its implications for the textual criticism activity. Starting from the fact that the nature of the textual object, especially in the case of ancient texts and literary texts, requires the editor to call into play very diverse knowledge – among which stands out the linguistic knowledge, but also the knowledge of the work, its characteristics and context – we advocate that a «philological» approach, multi and interdisciplinary, of the text editing is still needed, desirably carried out by teams of experts in different scientific fields. We exemplify, among others,with the case of the editions of the Sermões, by Vieira.

Manual de la comunicación inclusiva

El Manual de la Comunicación Inclusiva es una guía para generar mensajes éticos acerca de las personas que tradicionalmente son consideradas “minorías” en Costa Rica. Pretende dar recomendaciones al momento de escribir o difundir mensajes audiovisuales sobre la gente con discapacidad, la infancia, las personas afrodescendientes, los hombres homosexuales, las mujeres lesbianas, las personas indígenas o migrantes, entre otros. Es un trabajo colectivo del curso semestral “Comunicación inclusiva” que se impartió en la Escuela de Ciencias de la Comunicación Colectiva de la Universidad de Costa Rica durante los años 2007 y 2008. La población estudiantil colaboró en su redacción. Las diferentes organizaciones de la sociedad civil también aportaron ideas. Además, estas organizaciones capacitaron semanalmente al estudiantado en cada uno de sus temas de interés. El trabajo de compilación y edición estuvo a cargo del profesor del curso. El Manual de la comunicación inclusiva aspira a que toda persona emisora de un mensaje, reflexione sobre la forma y el contenido antes de emitirlo con el fin de lograr un producto comunicacional, que aliente el respeto y la inclusión de todas las personas dentro de una sociedad, que aún no logra superar todas las manifestaciones de discriminación. The Inclusive Communication Manual is a guide that allows us generate ethical messages about people or groups of people who are traditionally considered in Costa Rica as “minorities”. It Intends to provide recommendations for the autho messages that has to do with people who have certain disability or about childhood, African American people, homosexual men, lesbian women, group of natives and migrants among others.  It’s a collective work from the “Inclusive Communication” course that took place at the “Collective Communication School of Costa Rica’s University” during the year of 2007 and 2008. The students collaborated in its redaction as well as different other organizations of the civil society who provided ideas. Also, these organizations trained the students on a weekly basis on each and everyone of the subjects in study. The work of compiling information and its editing was done by the professor of the course.The Manual of Inclusive Communication intends to make the person who sends a message, think about the message, its content and form, before sending the message in order to accomplish a communicational product that will reinforce the respect and the inclusion of every single person within a society which even nowadays it can’t overcome the different manifestations of discrimination.

Genus seditiosorum. L'oratoria dei populares nelle testimonianze e nei frammenti (133-44 a.C.)

Il lavoro verifica l’ipotesi dell’esistenza, durante la tarda repubblica romana (133-44 a.C.), di uno stile oratorio riconoscibile come proprio dei populares. Per identificarne le caratteristiche tecniche distintive si procede, previa revisione e aggiornamento dell’edizione critica di riferimento (Malcovati 19764), alla traduzione delle testimonianze e dei frammenti oratori relativi ai 25 principali esponenti della pars popularis (da P. Licinio Crasso Divite Muciano a G. Scribonio Curione il Giovane) e al commento di tali testi. Nell’introduzione vengono discussi, alla luce di un’esposizione dettagliata dei relativi status quaestionis e di una rilettura delle fonti, i seguenti punti: esistenza dei populares; identificazione degli oratori populares; modalità di selezione e trasmissione del materiale oratorio e caratteristiche della sua tradizione; stato del materiale e modalità migliori di edizione; eloquentia popularis in Cicerone (impiegata anche dagli ottimati); stile oratorio di Gaio Gracco, di Giulio Cesare e degli oratori graccani, mariani e cesariani; riformulazione della categoria critica (eloquentia popularium) e conclusioni storiche e stilistiche. Nella trattazione sono integrati i risultati della ricerca, che consentono di formulare di volta in volta un giudizio autonomo. I dati vengono proposti anche in forma di tabelle in tre appendici, che presentano: l’attività politico-legislativa di G. Gracco, Saturnino, Clodio e Cesare a confronto (1), le figure e gli aspetti retorici rilevati nei frammenti (2.1), i giudizi sullo stile e le qualità retoriche riscontrati nelle testimonianze (2.2). Nel commento si rende ragione delle principali questioni filologiche, storiche e storiografiche relative a ciascun passo, mentre il focus è posto sugli aspetti linguistici e retorici. Vengono messe in luce le indicazioni offerte dalla fonte sul contesto performativo, per poi passare all’analisi puntuale (sinora un desideratum della critica) degli argumenta e dello stile oratorio e studiare, infine, come tali dati si inseriscano nel quadro complessivo dell’eloquenza di questo gruppo di oratori.

Edizione critica de "Il podere" di Federigo Tozzi

Le opere di Federigo Tozzi hanno conosciuto una fortuna critica sempre crescente, nel corso del Novecento, sebbene i testi delle stampe che ancora oggi leggiamo siano segnati dal destino sfortunato del loro autore: Tozzi, morendo a soli trentasette anni, non poté curare né approvare le edizioni di una parte cospicua dei propri scritti. Così, anche il te-sto che costituisce la vulgata di un romanzo caposaldo come Il podere è quello stabilito da Glauco Tozzi, figlio dell’autore, negli anni Sessanta per Vallecchi, a sua volta larga-mente fondato sulla princeps Treves curata dalla vedova dell’autore, Emma Palagi. La presente tesi di dottorato propone l’edizione critica del Podere di Tozzi, inseren-dosi nei lavori per le Edizioni Nazionali cui è destinata. La tesi pertanto è strutturata se-condo una scansione tipica dell’edizione di studio: una nota al testo, contenente le de-scrizioni e le analisi dei testimoni originali, la ricostruzione cronologica della genesi del romanzo e l’ipotesi di lavoro adottata. Dopo la dichiarazione delle norme per la costitu-zione di testo e apparato, segue il testo critico del romanzo, con apparato genetico a piè di pagina. La tesi si conclude con tre appendici, la prima contenente il testo parziale del-le ultime bozze di stampa del romanzo, corredate di apparato che ne descrive le diffe-renze rispetto al testo dattiloscritto e le correzioni d’autore qui aggiunte. Alla seconda appendice è invece destinato il breve testo di Luigia, che è quanto rimane testimoniato di un sequel del Podere. Nella terza appendice sono raccolte le riproduzioni fotografiche di alcune carte originali, utili durante la lettura della nota al testo.
