Little Memories of the Everyday: A Dialogue between Julio Cortázar and Georges Perec

El siguiente artículo presenta las principales líneas de investigación de mi ensayo Pequeñas memorias y escritura de lo cotidiano. Cortázar, Perec y sus ecos contemporáneos (2021). En particular, el análisis de ciertos “micro-géneros” literarios como las “instrucciones” o los “trabajos prácticos”, ligados a la exploración de lo cotidiano, nos permitirá analizar la obra de Julio Cortázar desde el punto de vista de los “proyectos a realizar”, una noción que nos obliga a repensar los vínculos entre la literatura y los protocolos experimentales del arte conceptual.The following article presents the main lines of research of my essay Little memories and everyday life writings. Cortázar, Perec and their contemporary echoes (2021). In particular, the analysis of certain literary "micro-genres" such as "instructions" or "practical works", linked to the exploration of the everyday, will allow us to analyze Julio Cortázar's work from the point of view of "projects to be carried out", a notion that forces us to rethink the links between literature and the experimental protocols of conceptual art.Dossier: Latinoamericano y escritor: aproximaciones críticas a la obra de Julio Cortázar desde el siglo XXIFacultad de Humanidades y Ciencias de la Educació

Poéticas del archivo: el “giro documental” en la narrativa rioplatense reciente

La literatura rioplatense del siglo XXI asiste a lo que el teórico americano Mark Nash identifica como un “giro documental”. Además de la incorporación de materiales documentales en el cuerpo de los textos, las obras que designaremos como “narraciones documentales” importan métodos propios a la investigación como la notación, la transcripción y el montaje de documentos o bien la citación de bibliografía variada. Este artículo se propone articular la reflexión teórica y el análisis literario de Aparecida (2015) de la escritora y periodista argentina Marta Dillon, un caso representativo para comprender las modalidades de funcionamiento de este dispositivo documental.La littérature rioplatense du XXIe siècle assiste à ce que le théoricien américain Mark Nash désigne comme un "tournant documentaire". Outre l’incorporation de matériaux documentaires dans les textes eux-mêmes, les œuvres que nous désignerons comme des "narrations documentaires" importent de méthodes issues de l’enquête tels que la notation, la transcription et le montage de documents ou bien la citation de bibliographie variée. Cet article propose d’articuler la réflexion théorique et l’analyse littéraire d’Aparecida (2015) de l’écrivaine et journaliste argentine Marta Dillon, un cas représentatif pour comprendre les modalités de fonctionnement de ce dispositif documentaire.Río de la Plata’s contemporary literature bears witness to what literary critic Mark Nash refers to as a “documentary turn”. In addition to the incorporation of documentary materials into their texts, the works we designate here as “documentary writings” employ research methods such as the notation, transcription and montage of documents or the citation of an elaborated bibliography. This article aims to articulate a theoretical consideration and a literary study of Argentinian writer and journalist Marta Dillon’s Aparecida (2015), a case representative for the understanding of this documentary device’s mechanics

El carácter cínico en Armando Ramírez, Guillermo Fadanelli y Rocío Boliver : una exploración de la escritura, el cuerpo y la sexualidad

Ce projet de recherche explore l’univers narratif de trois auteurs mexicains : Armando Ramírez, Guillermo Fadanelli et Rocío Boliver. En apparence dissemblables entre eux, leurs œuvres partagent une qualité que je propose ici d’identifier de « cynique ». Le cynisme, en tant qu’approche théorique, ouvre des possibilités interprétatives pour les manifestations artistiques, culturelles et politiques dans lesquelles est évident une friction avec les systèmes de valeurs dominantes. À travers différents langages (le roman, le conte, le récit et la performance), l’univers discursif de ces auteurs exprime un malaise envers le monde, réfléchit sur les conflits existentiels du sujet social mexicain et s’approprie de l’écriture, du corps et de la sexualité comme matière de dénonciation pour exhiber les dispositifs politiques avec lesquels vont être façonnées les catégories sociales ainsi que les canons et normes qui vont régler les codes éthiques et esthétiques de l’environnement culturel. En même temps, dans ces productions, le corps et la sexualité émergent comme une irruption et déplacement des discours en amenant l’exercice plein du langage corporel et écrit au bout de l’abjection. Dans le cas d’Armando Ramírez, le caractère cynique se construit à partir de la violence du langage et de l’attaque sexuelle pour dénoncer, depuis la voix du secteur dominé, le conflit historique des classes sociales. En ce qui concerne Guillermo Fadanelli, le cynisme va s’exprimer à partir de la destruction des grands récits qui donnent un sens linéal à l’existence. L’auteur profane l’écriture, les genres littéraires, la famille, la figure maternelle et les tabous sexuels. De son côté, l’œuvre de Rocío Boliver devient cynique lorsqu’elle conteste l’absence d’une représentation positive de la sexualité et de la vieillesse féminine. Cet artiste fait appel à la non-identification avec la religion catholique et les mécanismes de capitalisation du corps. Toutes ces raisons nous permettent de situer ces trois auteurs dans une tradition cynique pas seulement occidentale, mais notamment mexicaine, car cette recherche reconnait aussi la présence historique du cynisme critique dans la production culturelle du pays et dans la construction des identités nationales.The present investigation explores the narrative universe of three Mexican authors: Armando Ramírez, Guillermo Fadanelli and Rocío Boliver. Despite obvious differences, their works share characteristics that I propose to identify as “cynical”. In this dissertation, we use cynicism as a theoretical approach that makes possible new interpretations of artistic, cultural, and political expressions that have entered into conflict with dominant value systems. Through different narrative genres and idioms (novel, short story, literary essays and performance), these authors’ shared discursive universe expresses a discomfort with the world and reflects on the existential conflicts of the Mexican social subject. The authors appropriate writing, the body and sexuality as prime material for the denunciation of the political devices that configure social categories, as well as the canons and norms that regulate the cultural environment’s ethical and aesthetic codes. At the same time, by taking bodily and written languages to the extremes of abjection, the body and sexuality emerge in these productions as an irruption and displacement of official discourses. Armando Ramírez gives his novel a the cynical dimension by using the violence of language and sexual assault to denounce, with the voice of the subjugated, a long history of class conflict. In Guillermo Fadanelli, cynicism expresses itself through the destruction of universal discourses that give linear meaning to existence. Fadanelli profanes writing, literary genres, the family as a social institution, the maternal figure and sexual taboos. For her part, Rocío Boliver’s work becomes cynical when she questions the absence of a positive representation of female sexuality and old age. She resorts to disidentification with the Catholic religion and the mechanisms of capitalization of the body. This allows me to situate these three authors in the Western, and especially Mexican, cynical tradition, as this dissertation also recognizes the historical presence of critical cynicism in Mexico’s cultural production and in the construction of its national identities.El presente proyecto de investigación explora el universo narrativo de tres autores mexicanos: Armando Ramírez, Guillermo Fadanelli y Rocío Boliver. Aparentemente disímiles entre sí, sus respectivas obras comparten un carácter que aquí proponemos identificar como cínico. El cinismo, como enfoque teórico, abre las posibilidades interpretativas de manifestaciones artísticas, culturales y políticas en las que se observa una fricción con los sistemas de valores dominantes. A través de distintos lenguajes (novela, cuento, ensayo y performance), el universo discursivo de estos tres autores expresa un malestar con el mundo, reflexiona sobre los conflictos existenciales del sujeto social mexicano y se apropia de la escritura, del cuerpo y de la sexualidad como material de denuncia. Con ello, exhibe los dispositivos políticos con los que son configuradas las categorías sociales, así como los cánones y normas que regulan los códigos éticos y estéticos del entorno cultural. Al mismo tiempo, el cuerpo y la sexualidad emergen en estas producciones como una irrupción y desplazamiento de los discursos al llevar a los extremos de la abyección el ejercicio pleno del lenguaje corporal y escrito. En el caso de Armando Ramírez, el carácter cínico se construye a partir de la violencia del lenguaje y del ataque sexual para denunciar, desde la voz del sector dominado, el histórico conflicto de clases sociales. En Guillermo Fadanelli el cinismo se expresa a partir de la destrucción de los grandes relatos que le dan un sentido lineal a la existencia. Este autor profana la escritura, los géneros literarios, la familia, la figura materna y los tabúes sexuales. Por su parte, la obra de Rocío Boliver se torna cínica cuando cuestiona la ausencia de una representación positiva de la sexualidad y de la vejez femenina, y recurre a la desidentificación con la religión católica y con los mecanismos de capitalización del cuerpo. Lo anteriormente dicho nos permite ubicar a estos tres autores en una tradición cínica no sólo occidental sino particularmente mexicana, ya que este ensayo también reconoce históricamente la presencia del cinismo crítico en la producción cultural del país y en la construcción de las identidades nacionales

Segregation effects in rectangular piles built up by a moving injection device

An experimental study of granular segregation is reported on rectangular grain piles built by dropping simultaneously grains of two different species from a funnel moving back and forth sinusoidally parallel to the length of the pile. Our experimental set-up allows us to control the following variables during the build-up of the pile: height of the injection point above the top, amplitude and velocity of its displacement and injection flow rate for each kind of grains. Glass beads of different diameters are used in the experiment. Preliminary experimental results demonstrate that the distance of the injection point from the top of the pile and the amplitude of the motion have the largest influence on the segregation.Fil: Klein, Federico.

Colonial Organization of Mine Labour in Charcas 1 (Present-Day Bolivia) and Its Consequences 2 (Sixteenth to the Seventeenth Centuries)

This article analyses the changes in the organization of labour during the sixteenth and seventeenth centuries in colonial Charcas, present-day Bolivia, focusing on the role that different colonial authorities played in this process and its consequences. The Spanish took advantage of the pre-Hispanic organization of labour from the beginning of their conquest. However, in a colonial context, labour relations changed significantly, and the architect of those alterations was Viceroy Francisco de Toledo. We examine the transformations in mine labour carried out by the Spanish colonial polity; these had a significant effect not only on mining, but also on all labour relations in the southern colonial Andes.Fil: Gil Montero, Raquel.

Estudo fitoquímico das folhas de capim annoni-2 (Eragrostis plana Nees) coletadas no inverno e verão

The Annoni-2 grass (Eragrostis plana Nees) is a poaceae that presents allelophatic potential as observed in other research. In this study, the extracts were obtained from leaves collected during summer and winter. The extraction process was performed using solvents in a increasing order of polarity (petroleum ether, etyl acetate and methanol) and the extracts were analyzed and compared regarding the composition and/or concentration of metabolites produced. The techniques utilized were high performance liquid chromatography and infrared spectroscopy, and, the data obtained from the infrared analisys was compared using PCA, then the fractionation of summer and winter ethyl acetate extracts was carried out and the isolated compounds were identified by spectrometric and spectroscopic methods: NMR 1H and 13C, experiments of HSQC and HMBC and GC-MS. The results show the extracts are rich when it comes to probable variety of chemical compounds. It is also observed that, statistically, the solvents used in the extraction process influence the diversity of chemical compounds more than the season in which the leaves were collected. Triacylglycerol and rotenoid were identified from the fractionation summer ethyl acetate extract, and the presence of a rotenoid in the leaves of Annoni-2 grass, can justify the allelopathic action observed in this species in other works.CNPqO Capim Annoni-2 (Eragrostis plana Nees) é uma poaceae que apresenta potencial alelopático conforme observado em trabalhos anteriores. Neste estudo os extratos, obtidos com solventes em ordem crescente de polaridade (éter de petróleo, acetato de etila e metanol), das folhas de Capim Annoni-2, coletadas no verão e inverno, foram analisados e comparados, levando-se em conta composição e/ou concentração de metabólitos produzidos, utilizando-se técnicas de Infravermelho e Cromatografia Líquida de Alta Eficiência, sendo que, os dados de Infravermelho foram comparados estatisticamente por PCA, em seguida realizou-se o fracionamento dos extratos de acetato de etila verão e inverno, as substâncias isoladas foram identificadas através de métodos espectrométricos e espectroscópicos: RMN de 1H e 13C, experimentos de HSQC e HMBC e CG-EM. Verificou-se que os extratos apresentam riqueza em termos de provável variedade de compostos químicos, além disso, observa-se que os solventes utilizados para a extração resultam, estatisticamente, em maiores diferenças, em termos de composição química, do que a estação do ano em que as folhas foram coletadas. Foram identificadas duas substâncias resultantes do fracionamento do extrato de acetato de etila verão, um triacilglicerol e um rotenóide. A presença de um rotenóide nas folhas de Capim Annoni-2, pode justificar a ação alelopática observada nesta espécie em outros trabalhos

Preventive Group Training Improves Children's Outcomes after Divorce:A Dutch Quasi-experimental Study

Worldwide, many children experience parental separation and divorce. This has a significant impact on their well-being, and emotional and behavioral functioning, and calls for prevention. To assess the effects of the Children of Divorce Intervention Program in the Netherlands (CODIP-NL) on 6- to 8-year-olds, we performed a quasi-experimental effect study. The study compared children receiving CODIP-NL (intervention: I, n = 104), children not receiving CODIP-NL but having divorced parents (divorced control: DC, n = 37), and children belonging to non-divorced families (non-divorced control: NDC, n = 138). Outcomes pertained to children's positive functioning, emotional and behavioral problems, and well-being. We assessed pre- to post-test differences in change in mother-reported outcomes between the intervention and control groups, and pre- to post-test differences in group leader reports. The intervention led to increases in mother-reported positive functioning (d = 0.97 I vs. DC; d = 1.04 I vs. NDC), and well-being (d = 1.00 I vs. DC; d = 0.84 I vs. NDC). Mother-reported child emotional and behavioral problems decreased after participation (total difficulties, d = 0.73 I vs. DC; d = 0.49 I vs. NDC). Group leader-reported pre- to post-test differences (

Effect of an Oxygen-Based Mechanical Drug Delivery System on Percutaneous Permeation of Various Substances In Vitro

Transdermal drug administration is an elegant method to overcome various side effects of oral or parenteral drug administration. Nevertheless, due to an effective skin barrier, which is provided by the stratum corneum, transdermal drug delivery is sometimes very slow and ineffective. Thus, the effect of a medical device (DERMADROP TDA) for transdermal penetration of drugs in conjunction with a special vehicle emulsion on percutaneous permeation of several substances (with different physicochemical properties) was investigated in Franz-type diffusion cells with porcine skin over 28 h. This medical device disperses pharmaceutical agents via oxygen flow through an application system, which is used in conjunction with specially developed vehicle substances. Substance permeation of various substances with different physicochemical properties (diclofenac, enrofloxacin, flufenamic acid, indomethacin, and salicylic acid) was examined after application with a pipette and with the medical device. Therefore, acceptor media samples were collected up to 28 h after drug administration. Drug concentration in the acceptor medium was determined via high-performance liquid chromatography. Enhanced permeation was observed for diclofenac, enrofloxacin, flufenamic acid, indomethacin, and salicylic acid after oxygen-based administration. This correlates negatively with the molecular weight. Thus, drug administration can effectively be enhanced by a medical device using oxygen

Essa interação química entre plantas ocorre devido a produção e liberação no ambiente de compostos do metabolismo secundário, o que torna essas substâncias atrativas para as pesquisas de novos bio-herbicidas. Foram obtidos extratos de raízes de E. plana coletadas nas quatro estações do ano, utilizando solventes de diferentes polaridades (éter de petróleo, acetato de etila e metanol). Realizou-se, então, fracionamento bioguiado dos extratos brutos obtidos, seguido do isolamento e identificação das substâncias presentes nos mesmos. Os dados dos bioensaios foram analisados por MLG e PCA, essas análises mostraram que os extratos em éter de petróleo de raízes coletadas no inverno e no verão apresentaram maior efeito fitotóxico sobre a germinação e o crescimento de Ipomoea grandifolia. Foram isolados 10 diterpenos do tipo neocassano dos extratos brutos de E. plana, inéditos na literatura, identificados por técnicas espectrométricas e espectroscópicas. Os experimentos de DRX do neocassa12(13),15-dien-14-ona (1) e do neocassa-12(13),15-dieno-3,14-diona (2) confirmaram um esqueleto do tipo neocassano e possibilitaram a definição da configuração relativa dos estereocentros da molécula. A definição da configuração absoluta dos estereocentros de neocassa-12(13),15-dieno-3,14-diona (2) e neocassa-12(17),15- dien-3-ona (7) foi realizada por VCD e definida como sendo 5R,8R,9S,10R e 5R,8S,9S,10R,13R, respectivamente. Os testes fitotóxicos com as substâncias 2, 9 e 10 mostraram que o 3-hidroxineocassa-12(17),15-dieno (10) provocou redução no comprimento da parte aérea e no comprimento da radícula de Euphorbia heterophylla e Ipomoea grandifolia, respectivamente. Enquanto o neocassa-12(13),15-dieno-3,14- diona (2) reduziu o índice de velocidade de germinação das espécies receptoras, resultando no menor valor dessa variável quando comparado com o herbicida glifosato.

This chemical interaction between plants occurs due to the production and release of secondary metabolism compounds into the environment, which makes these substances attractive for research on new bio-herbicides. Extracts of E. plana roots collected during each season throughout the year were obtained using solvents of different polarities (petroleum ether, ethyl acetate and methanol). Then, bioassay-guided fractionation of the crude extracts was carried out, followed by the isolation and identification of the substances present in them. The data from the bioassays were analyzed by MLG and PCA, these analyzes showed that extracts in petroleum ether from roots collected in winter and summer had greater phytotoxic effect on the germination and growth of Ipomoea grandifolia. Ten neocassane diterpenes were isolated from the crude extracts of E. plana, unpublished in the literature, identified by spectrometric and spectroscopic techniques. The DRX experiments of neocassa-12(13),15-dien-14-one (1) and neocassa-12(13),15-diene3,14-dione (2) confirmed neocassane-type skeleton and made it possible to define the relative configuration of the molecule's stereocenters. The absolute configuration of the stereocenters of neocassa-12(13),15-diene-3,14-dione (2) and neocassa-12(17),15- dien-3-one (7) was defined by VCD as 5R,8R,9S,10R and 5R,8S,9S,10R,13R, respectively. Phytotoxic tests with compounds 2, 9 and 10 showed that 3- hydroxyneocassa-12(17),15-diene (10) caused reduction of the shoot length and of the radicle length of Euphorbia heterophylla and Ipomoea grandifolia, respectively. While neocassa-12(13),15-diene-3,14-dione (2) caused more reduction in the germination speed index than herbicide glyphosate.
