Frank Wilderson: I introduce a semiotic configuration. The point is, at important levels of abstraction, people who are positioned as Black—which is very different from saying people who think of themselves as Black. One of the basic premises of Afropessimism, which makes it resonate with psychoanalysis or Marxism, is that where one is positioned in a paradigm might not be where one thinks one is or where one desires to be. When I teach undergraduates, I say: “Look, I used to (...) study neorealism. In these neorealist films, we have these people who are bona fide fascists, and then you have those people in the Communist Party, so they could not agree on much. They don’t see themselves as having much of a connection. But in a Gramscian sense, they are both positioned as the host of capitalist parasites. Both groups rely on the wage. So, they are both workers.” One of the big points with respect to the narratological question is that I, as a Black person, trained at Columbia University in creative writing, trained at UC Berkeley in critical theory, love narrative, but narrative does not love me. In other words, it is impossible for me to be “emplotted” as a speaking subject. I can only be “emplotted” as an object of narrative. But I am always struggling to attain that love of humanity; and if I were to attain it, the Human would not have a foil against which to know itself. So, what I am saying is that in a book like Red, White & Black, I am just being very categorically clear about the divisions. In Afropessimism, I am actually talking about the desire of a sentient being who cannot be allowed into an arena where people are recognized and incorporated, in Lacanian terms, as “contemporaries” of human beings. So, there is all this back and forth. I don’t think this speaking subject in Afropessimism ever achieves anything in particular. It is always struggling toward being a subject that can actually travel on a narrative arc and yet ultimately is an object that can never travel from dispossession to redemptive recovery. (shrink)

La presencia e integración de la investigación cualitativa a los protocolos de investigación biomédica ha cobrado cada vez mayor relevancia, por la importancia de la antropología cultural. El caso particular de la etnografía adquiere aún más preeminencia en relación con la definición de riesgo para el sujeto de investigación. El presente artículo expone las principales características de la investigación etnográfica que deben ser evaluadas por un comité de ética de la investigación, y define una serie de recomendaciones para la evaluación (...) del riesgo para los sujetos que se someten a este tipo de estudio. Los miembros de los Comités de Ética en Investigación deben tener en cuenta la etnografía para realizar a cabalidad su función. (shrink)

Adaptive optics are techniques used for processing the spatial resolution of astronomical images taken from large ground-based telescopes. In this work, computational results are presented for a modified curvature sensor, the tomographic pupil image wavefront sensor, which measures the turbulence of the atmosphere, expressed in terms of an expansion over Zernike polynomials. Convolutional neural networks are presented as an alternative to the TPI-WFS reconstruction. This technique is a machine learning model of the family of artificial neural networks, which are widely (...) known for its performance as modeling and prediction technique in complex systems. Results obtained from the reconstruction of the networks are compared with the TPI-WFS reconstruction by estimating errors and optical measurements. The reconstructed wavefronts from both techniques are compared for wavefronts of 153 Zernike modes. For this case, a detailed comparison and grid search to find the most suitable neural network is performed, searching between multi-layer perceptron, CNN and recurrent networks topologies. In general, the best network was a CNN trained for TPI-WFS reconstruction, achieving better performance than the reconstruction software from TPI-WFS in most of the turbulent profiles, but the most significant improvements were found for higher turbulent profiles that have the lowest r0 values.

Esports have transformed playing video games into a competitive activity that bears similarities to sports and the processes of sportization. Taking as a starting point the concept of sports as competitive games, the objective of this work is to analyse the sportization of esports, as well as the impact of esports on the concept of sports and their implications on sports in the immediate future. Sports and esports are two different realities that interact with each other. This is a conceptual (...) problem for sports, and it also defines a practical challenge in the immediate future of sports. The virtual environment offers new possibilities in sports, such as broadening the possibilities of confrontation and competition development, contributing to reducing the environmental impact of certain sports, improving safety and maintaining the physical integrity of athletes, and increasing social justice and equality of chances in sports competitions. The challenge, therefore, is to try to bring esports and sports closer together, even moving toward hybrid sports, as addressed throughout this article. (shrink)

This study examines the effect of integrating sustainability into corporate strategy on various aspects of shareholder value creation and financial performance in the British capital market. The employed method is based on the content analysis of corporate disclosures and a new technique for assessing the adoption of the corporate sustainability concept. Using extensive data of FTSE 350 firms covering the years 2006–2012, 65 companies were selected as meeting corporate sustainability criteria. For the above period, we find that these firms were (...) characterized by higher financial risk exposure, lower asset growth rates, lower BV/MV ratios, lower EVA ratios, and higher MVA ratios. Such relations were generally present among different size and industry groupings. The results support the thesis that firms that incorporate sustainability issues into their business operations are better able to leverage their resources toward stronger financial performance and shareholder value creation than other companies. The paper contributes to the literature by offering a more holistic approach to corporate sustainable performance measurement and shedding additional light on its relation to financial performance in the context of the recent global financial crisis and its direct aftermath.

El despido intempestivo ha sido uno de los causales con mayor incidencia en el tema laboral, debido que el patrono no establece condiciones claras de la desvinculación, por lo que, se vulnera los derechos de los trabajadores. Elaborar un documento de análisis jurídico crítico que evidencie como la incidencia del despido intempestivo vulnera los derechos laborales Constitucionales en el Ecuador. El artículo fue una revisión sistemática con un diseño transversal. Para la busqueda de información se utilizó las principales platafomas digitalez (...) con evidencia científica en el campo jurídico, además de establecer criterios de inclusión y exclusión para obtener la información con mayor relevancia al estudio. De acuerdo con los casos analizados se evidenció que los despidos intempestivos se los realiza sin una justificación clara, que motive la desvinculación del trabajador vulnerando su derecho a tener una estabilidad laboral, un trabajo digno. A pesar de que la Constitución y las leyes laborales establecen claras protecciones para los trabajadores, la realidad demuestró que estas normativas no siempre se aplican de manera efectiva, lo que no solo socava el derecho a la estabilidad laboral y un trabajo digno, sino que también limita el acceso a la justicia, afectando el bienestar tanto económico como psicoemocional de los dependientes, destacando la necesidad urgente de fortalecer los mecanismos de protección laboral, garantizando la aplicación rigurosa de las leyes existentes en Ecuador.

Introduction: Physical distancing under the coronavirus disease 2019 pandemic had a significant impact on lifestyles, including exercise routines. In this study, we examined the relationship between mental health and addictive behaviors, such as excessive exercise and the use of image and performance enhancing drugs across 12 sport disciplines.Materials and methods: A large cross-sectional sample of the adult population was surveyed. The mean age was 33.09. The number of male participants was 668. The use of IPEDs was assessed in conjunction with (...) psychometric measures such as the Exercise Addiction Inventory and the Appearance Anxiety Inventory. The participants were grouped into activity group and non-activity group according to the presence or absence of their exercise habits. The results were compared between these groups, as well as across sport disciplines, while taking into account the relationship between different psychological measures and IPEDs consumption.Results: The frequency of IPEDs use was higher among AG than NAG, although AG participants reported less history of addictions than NAG. The logistic regression analysis revealed that scores equal to or above cutoff points, in both the EAI and AAI, predicted the IPEDs use. Regarding the differences across the various sport disciplines, those who were involved in practicing Weight Lifting and Cross Fit were found to be more at risk of excessive exercising and more inclined to use a wide range of IPEDs.Conclusions: Although exercise could help to increase well-being and prevent addictions during the COVID-19 pandemic, our results show that those in the AG are particularly vulnerable to excessive IPEDs use. Sport disciplines associated with higher EAI and AAI scores have also shown a higher tendency to excessive IPEDs use. Furthermore, the factor of having above the cutoff scores in EAI or AAI in each sport could indicate larger IPEDs consumption regardless of the discipline. In light of the current findings, it is necessary to better define the “non-excessive” levels of exercise in various sport disciplines and an adequate intake of IPEDs to ensure the safety and well-being of people during a pandemic.

Background: Serious games have shown positive results in increasing motivation, adherence to treatment and strengthening the therapeutic alliance in multiple psychiatric disorders. In particular, patients with impulse control disorders and other disorders in which the patient suffers from inhibitory control deficits have been shown to benefit from serious games.Aim: The aim of this study was to describe the characteristics and to evaluate the usability of a new serious videogame, e-Estesia. This serious videogame was designed to improve emotion regulation in patients (...) with gambling disorder. Preliminary results from a pilot sample are also reported.Method: A pilot sample of 26 patients undergoing treatment for GD was recruited. Participants used e-Estesia on a tablet, which was connected to a thoracic band that sent heart rate and heart rate variability data to the videogame platform in order to provide biofeedback. The System Usability Scale was completed by patients to determine the usability of e-Estesia.Results and Discussion: e-Estesia performed comparatively well for all the explored groups. Around 84.6% of the patients endorsed that it was easy to use. Female patients with GD presented higher HRV during the use of the serious videogame compared to men. (shrink)

En este artículo nos disponemos desarrollar la tesis según la cual la crítica elaborada por Santiago Castro-Gómez a Enrique Dussel se trató de una desnaturalización del análisis del filósofo argentino sobre el proyecto moderno, en la cual Castro-Gómez puso de relieve las prácticas de las herencias coloniales como condición de posibilidad para la emergencia de la modernidad, sin necesidad de recurrir a la figura fundante del sujeto, aspecto que sí se encuentra presente en la propuesta del mendocino. Esta tesis se (...) demostrará mediante un diálogo crítico entre estos dos autores en torno al problema de la modernidad y la colonialidad a partir de tres claves analíticas, la posmodernidad, la modernidad y la descolonización, con el fin de pensar el modo en que las prácticas coloniales operaron en el proyecto moderno a través del uso de los valores presentes en la misma modernidad, sin que ello implique caer en una supuesta desmodernización.

The relationship between spiritual wellbeing and ethical orientations in decision making is examined through a survey of executives in organizations listed on the Australian Stock Exchange. The four domains of spiritual well-being, personal, communal, environmental and transcendental (Fisher, Spiritual health: its nature and place in the school curriculum, PhD thesis, University of Melbourne, 1998; Gomez and Fisher, Pers Individ Differ 35:1975–1991, 2003) are examined in relation to idealism and relativism (Forsyth, J Pers Soc Psychol 39(1): 175–184, 1980). Results reveal (...) that spiritual well-being, in particular the communal domain of spiritual well-being, is correlated with and predictive of idealism. However, the relationship between spiritual well-being and relativism is weak. Implications of the study are discussed in terms of developing managerial programs that enhance communal well-being which should lead to greater idealism in decision making. Limitations of the study and future research opportunities are outlined. (shrink)

En el artículo se presenta una descripción de la crítica a la modernidad demostrada por el filósofo argentino Enrique Dussel señalando el proceso mediante el cual se fue configurando como un proyecto europeo. En efecto, el artículo plantea que dicho proyecto se postula en el marco de una centralidad que iría a justificar las prácticas coloniales implementadas. Para lograr mantenerse dentro de la dinámica histórica, estos hábitos empezaron a circunscribirse en discursos míticos so pretexto de justificar la violencia efectuada en (...) las prácticas. Dussel, por su parte, propone la categoría de Transmodernidad como proyecto alternativo emergente a la modernidad europea. No obstante, esta propuesta es objeto de críticas como las del filósofo colombiano Santiago Castro-Gómez. (shrink)

RESUMEN Partiendo de la discusión del concepto de carne, en este trabajo analizo la común estructura ontológica/biopolítica que comparten los animales humanos y no humanos. Para ello me sirvo de los feminismos materiales y utilizo los hallazgos teóricos del feminismo animalista. También examino la noción de "encierro" en tanto concepto biopolítico que produce un nuevo tipo de ser vivo. Todo ello para, en último lugar, articular un sentido positivo del concepto de encarnación que permita construir comunidad animal. ABSTRACT In this (...) article, I analyze the common ontological/biopolitical structure shared by human and non-human animals, starting out from the discussion of the concept of flesh. To that effect, I resort to material feminisms and to the theoretical findings of animal rights feminism. I also examine the notion of "enclosure" as a biopolitical concept that produces a new kind of living being. All of this serves to formulate a positive sense of the concept of incarnation that allows for the construction of a animal community. (shrink)

In "'Yes" and "No'" (2000), Ian Rumfitt proposed bilateralism--a use-based account of the logical words, according to which the sense of a sentence is determined by the conditions under which it is asserted and denied. One of Rumfitt's key claims is that bilateralism can provide a justification of classical logic. This paper raises a techical problem for Rumfitt's proposal, one that seems to undermine the bilateralist programme.

Frente a la ciencia, que es un saber basado en pruebas, tanto la filosofía como la religión profesan saberes improbables o inverificables, es decir carentes de un fundamento satisfactoriamente objetivo. Exigen un compromiso subjetivo de un tipo muy especial -a la vez frágil y avasallador- entre quienes los aceptan. En el caso de la religión ese compromiso es la creencia en la tradición revelada, en el de la filosofía es el pensamiento que fragua una trama argumental. Ambos casos están directamente (...) relacionados a nuestra mortalidad: la religión para salvarnos de la muerte, la filosofía para permitirnos afrontarla sin vileza. ¿Qué puesto tiene cada uno de estos saberes en la democracia moderna? ¿Es la fidelidad a la democracia misma una creencia religiosa o un pensamiento filosófico?

A identificação e análise de princípios epistêmicos têm possibilitado ganhos significativos no estudo do ceticismo nas últimas décadas, isso não significa que estejamos próximos de um consenso sobre quais princípios devem ser aceitos. Entendendo p como qualquer proposição que geralmente admitiríamos saber, como “aqui há uma mão”, e sk como alguma proposição incompatível, como “estou sendo enganado por um gênio que me induz a crer em coisas que não existem”, o argumento canônico para o ceticismo acadêmico pode assim ser formalizado: (...) Se S está justificado ao crer que p, então S está justificado ao crer que ~sk; S não está justificado ao crer que ~sk, logo, S não está justificado ao crer que p. Implicitamente, pode-se notar: o cético advoga que a relação epistêmica tida com uma proposição deve ser preservada nas proposições decorrentes dessa e, uma vez falho o cumprimento dessa exigência, resulta-se inescapavelmente no ceticismo. Para resolver essa questão, alguns filósofos rejeitaram o ceticismo negando a premissa. Outros, como Klein, concedem ao cético, porém negam sua conclusão, apontando que este falha em sua defesa de. Discute-se aqui a viabilidade dessas alternativas. (shrink)

We present a new functional interpretation, based on a novel assignment of formulas. In contrast with Gödel’s functional “Dialectica” interpretation, the new interpretation does not care for precise witnesses of existential statements, but only for bounds for them. New principles are supported by our interpretation, including the FAN theorem, weak König’s lemma and the lesser limited principle of omniscience. Conspicuous among these principles are also refutations of some laws of classical logic. Notwithstanding, we end up discussing some applications of the (...) new interpretation to theories of classical arithmetic and analysis. (shrink)

We define a notion of realizability, based on a new assignment of formulas, which does not care for precise witnesses of existential statements, but only for bounds for them. The novel form of realizability supports a very general form of the FAN theorem, refutes Markov's principle but meshes well with some classical principles, including the lesser limited principle of omniscience and weak König's lemma. We discuss some applications, as well as some previous results in the literature.

La figura de Karl Marx ha sido vista por algunos católicos como ateísta dada las expresiones tomadas fuera de contexto del pensador de Tréveris. No obstante, con rigurosidad el filósofo Enrique Dussel presenta una imagen muy diferente. Marx en realidad va a ser un crítico de los cristianos burgueses de su época, que confundieron el pensamiento de Jesús con un fetichismo bajo el cual terminaron sacrificando vidas inocentes. De hecho, llegaron a impulsar una violencia de lo sagrado que alcanza incluso (...) hasta nuestros días. Por esta razón es fundamental hacer una relectura del pensamiento marxista desde la teología de la liberación para contribuir a la emancipación del ser humano de todo aquello que lo deshumaniza “en nombre de Dios”.
