Textos sobre violencia: de lo impuro. (Contaminaciones, equívocos, temblores)

This article interrogates a certain philosophical scene – one which constitutes itself through the position of what Jacques Derrida calls “the ethical instance of violence.” In the course of the essay, I analyze this quasi-juridical scene through readings of Aristotle, Walter Benjamin, and Giorgio Agamben among others. The scene, built on texts on texts on violence, demands a logic of purity; it is wary of contaminations and equivocations. And yet it thrives on them. In analyzing the implications of text, writing, and trace for the philosophical discourse on violence, I follow Derrida “just to see” what could make the scene tremble.Este artículo interroga cierta escena filosófica –una que se constituye a través de la posición de lo que Jacques Derrida llama “la instancia ética de la violencia”. En el curso del ensayo, analizo esta escena cuasi-jurídica a través de las lecturas de Aristóteles, Walter Benjamin y Giorgio Agamben, entre otros. La escena, construida sobre textos sobre textos sobre violencia, exige una lógica de la pureza; es recelosa de conta-minaciones y equívocos. Y sin embargo, se alimenta de ellos. Analizando las implicaciones del texto, la escritura y la huella para el discurso filosófico sobre la violencia, sigo a Derrida “solo para ver” que puede hacer temblar esta escena

Scale, Scope, and Specialization Effects on Retailers’ Procurement Strategies: Evidence from the Fresh Produce Markets of São Paulo

Worldwide, the emergence of large supermarket chains in food retail markets is often associated with the marginalization of smaller retailers. A notable exception exists in Brazil, however, where small retailers have held their place in the market and recently even gained ground. The literature investigating how retail concentration has affected agrifood chains has focused activities of the largest retail chains, implicitly holding the scale, scope and specialization of retailers’ input needs constant, and overlooking the influence of these factors on retailers’ procurement strategies. This paper tests hypotheses regarding these variables’ effects on retailers’ fresh produce procurement strategies. Data is drawn from a survey of retailers in metropolitan São Paulo. The research results provide insight into factors underlying retailers’ procurement strategy choices and tradeoffs among options. The results support the fundamental hypothesis of the paper that research on the competitive strategies of smaller retailers in a context of market domination by large retailers should not focus exclusively on the degree to which the smaller retailers imitate the larger retailers rather it should account for the possibility that the underlying characteristics of the retailers may make diverse competitive strategies appropriate.scale, scope, specialization, procurement strategy, fresh produce, retail, Political Economy, L22,

Solar Irradiance Anticipative Transformer

This paper proposes an anticipative transformer-based model for short-term solar irradiance forecasting. Given a sequence of sky images, our proposed vision transformer encodes features of consecutive images, feeding into a transformer decoder to predict irradiance values associated with future unseen sky images. We show that our model effectively learns to attend only to relevant features in images in order to forecast irradiance. Moreover, the proposed anticipative transformer captures long-range dependencies between sky images to achieve a forecasting skill of 21.45 % on a 15 minute ahead prediction for a newly introduced dataset of all-sky images when compared to a smart persistence model.Comment: 10 pages, 6 figures, Best Paper submission for CVPR 2023 workshop EARTHVISION 202

New (Internal) Wave Generation - Laboratory Experiments

In this fluid dynamics video, we demonstrate the experimental generation of various internal wave fields using a novel wave generator. Specifically, uni-directional internal wave beams and vertical modes 1 and 2 are generated and visualized using Particle Image Velocimetry. Further details and analysis of these experiments can be found in [1].Comment: 2 pages, no figures, article linked to a fluid dynamics video submitted to the Gallery of Fluid Motion, APS DFD 200

à corps: The corpus of deconstruction

This article pursues the exploration of how contemporary works of deconstruction can challenge preconceptions of the body and embodiments and interrogate their limits, particularly in relation to intertwined foldings of desire, gender, race and sexuality. Through readings of Jacques Derrida and Sarah Kofman, the authors show that deconstruction allows for an understanding of the body or bodies that goes beyond the present body — indexed as human, male, white, able, living body — thus opening up towards the thinking of bodies and corporealities exceeding the limitations of Christian transsubstantiation and of the Eucharist. The deconstructive body is not one of communion; it is one of (self-)interruption, différance and non-presence. It is the other's body — or the body as otherly. The authors then analyse the ethical-political implications of this thinking of another body, one inassimilable by Western metaphysics, and marked by incalculable sexual differences, animality, undecidable life-death, machinicity, monstrosity, and so on

Diferencia sexual, diferencia ideológica : Lecturas a contratiempo (Derrida lector de Marx y Althusser en la década de 1970 y más allá)

Este ensayo presenta una descripción de los escritos inéditos de Jacques Derrida sobre Marx y Louis Althusser en la década de 1970, y un estudio de conceptos como ideología, diferencia sexual, reproducción, violencia, dominación o hegemonía en perspectiva deconstructiva. Se trata de pensar en una otra economía, más allá de la economía del cuerpo propio. El artículo fue publicado en el Volumen 7 de la Revista Demarcaciones, "a 25 años de Espectros de Marx.

Pas de course. Notes piquées sur le séminaire « GREPH. Le concept de l’idéologie chez les idéologues français »

Afin d’examiner la forme et la fonction « cours » dans le corpus de Derrida, je propose une lecture du séminaire inédit « GREPH. Le concept de l’idéologie chez les idéologues français » (1974-1975). Ce séminaire fut mené dans le cadre des engagements politico-institutionnels du GREPH (Groupe de recherches sur l’enseignement philosophique). Il constitue donc un point d’entrée privilégié pour saisir le rapport complexe que Derrida entretient avec l’enseignement, et plus généralement avec l’institution philosophique. Au cours de ce séminaire, Derrida s’intéresse au « corps enseignant » en tant qu’il fonctionne comme « machine reproductrice » au sein de l’organisation économique générale de la société. Courant deux lièvres à la fois, Derrida mêle une réflexion généalogique sur l’histoire de l’enseignement philosophique en France et en Europe à une analyse théorique de concepts marxistes et sociologiques tels que « capital », « reproduction », ou « appareil idéologique ». À travers des lectures déconstructrices et transformatrices de Marx et d’Althusser, Derrida s’efforce de penser une autre économie — une économie du texte débordant la logique reproductrice qu’il identifie aussi bien chez les économistes classiques que chez leurs critiques marxistes.In order to examine the form and function of the course in Derrida’s corpus, I propose a reading of the unpublished seminar “GREPH. Le concept de l’idéologie chez les idéologues français” (1974-1975). This seminar was given as part of Derrida’s political and institutional engagements within GREPH (Groupe de recherches sur l’enseignement philosophique). As such it offers many insights into Derrida’s complex relationship with teaching and more broadly with the institution of philosophy. In the course of the seminar, Derrida examines the “teaching body” inasmuch as it functions as a “reproductive machine” within the general economic organization of society. Running on two different tracks at once, Derrida combines a genealogical study of the history of the teaching of philosophy in France and Europe with a theoretical analysis of Marxist and sociological concepts such as “capital”, “reproduction”, and “ideological apparatus”. Through deconstructive-transformative readings of Marx and Althusser, Derrida proposes to think another economy — an economy of the text exceeding the reproductive logic which he discerns in classical economists as well as in their Marxist critics

Before the Specters: The Memory of a Promise (from the Archives)

This text was prompted by a forum discussing the legacy of Jacques Derrida’s Specters of Marx, twenty-five years after its publication. In this short essay, I explore the book’s influence on the fields of Marxism, post-Marxism, and beyond. With the problematic of heritage and legacy in mind, I raise the questions of sexual difference and dissemination as that which comes to interrupt the genealogical logic of inheritance understood as filiation and reproduction. I show that Derrida’s book, besides questioning reception and influence, yet remains to be read, especially in light of ongoing archival research on Derrida’s numerous engagements with Marx and Marxist thought in a series of unpublished seminars from the 1970s. This is done more specifically through a reading of an unpublished seminar from 1974-1975, dealing with the Marxian concepts of ideology and division of labor – which Derrida interrogates more particularly in relation to sex, sexuality, and sexual differences.
