The presence of ibuprofen in wastewater is a topic of global interest, and the mechanisms and behavior of its correlation with its elimination in ecological systems, such as constructed wetlands, is a little known topic. The objective of this study was to perform a correlational analysis of the behavior of the emerging contaminant ibuprofen in a horizontally constructed wetland in a tropical climate planted with the ornamental plant Spathiphyllum blandum. 10 experimental units were used at the mesocosm level of 20 (...) L, 5 planted with Spathiphyllum B., and 5 without plants. The elimination of ibuprofen was measured and the correlation was analyzed using computational methods and neural networks. Spathiphyllum blandum was used in this study. The removal of ibuprofen in HC was significantly improved by up to 23% compared with that in non-planted systems. Based on the prediction obtained from ibuprofen in the effluent, it can be concluded that it has an exponential decay behavior tending to zero, and the model obtained explains in an acceptable way the relationship between the height of the plant and the concentration of ibuprofen in the effluent, reaffirming that this relationship is inverse. Further studies should be conducted to understand the behavior of these compounds in relation to different species of tropical plants. (shrink)

En este artículo examino el problema del estatus epistémico de las teorías científicas, a la luz de la epistemología de Popper. A partir del planteamiento controversial “ninguna teoría científica es verdadera” (A) que resulta un buen candidato para expresar de manera sintética una de las implicaciones fundamentales de la teoría popperiana de la verosimilitud, analizo algunas críticas a la concepción falibilista de la ciencia y sugiero formas de desarrollar apropiadamente el sentido de (A), junto con el de otros planteamientos de (...) la misma familia. Argumentaré que sólo mediante estos planteamientos podemos comprender de manera adecuada la empresa de la ciencia, y que ellos no representan el colapso de la epistemología. Por otra parte, mostraré cómo construir estos planteamientos de tal suerte que salgan airosos ante las críticas más comunes. Así mismo, examinaré el sentido de la locución “conocimiento científico” con el fin de mostrar que no es aconsejable interpretarla según el sentido tradicional de la palabra “conocimiento”. Ofreceré razones para concluir que si el enunciado (A) y sus parientes se matizan correctamente, estaremos en una posición mejor para conseguir una representación funcional de la empresa de la ciencia.

Las discusiones sobre epistemología confiabilista suelen centrarse en elexamen de teorías de proceso confiable, según las cuales una creencia esjustificada syss es producida por procesos que son generalmente confiables.Pero la noción de “proceso-tipo confiable” es muy controvertida. Por ejemplo,autores como Conee y Feldman consideran que las teorías de la justificaciónde proceso confiable son irremediablemente defectuosas, debido al “problemade la generalidad”. En este trabajo me propongo bosquejar la idea central dejustificación en términos confiabilistas, y determinar hasta qué punto sepueden sostener las (...) críticas de Conee y Feldman contra la noción alstonianade confiabilismo de proceso. Finalmente, sugiero una estrategia paraneutralizar las objeciones de Conee y Feldman, y una propuesta esquemáticapara justificar los procesos-tipo que generan las creencias confiables. (shrink)

Me complace presentar a la comunidad académica nacional e internacional el fascículo 29 de la revista Discusiones Filosóficas. Como seguramente es conocido por la mayor parte de los lectores, el sistema de indización de revistas colombiano está experimentando una radical transformación, cuyas consecuencias, entre otros aspectos, afectan notablemente el futuro de las ublicaciones científicas periódicas en el área de las humanidades y las ciencias sociales. En efecto, COLCIENCIAS, sin tomar en cuenta la opinión de los editores de revistas colombianos, ni (...) a de la mayor parte de las universidades del país ha decidido hacer de indicadores como los informes de ciertas bases de datos pagas (ISI Web of Science, Scopus) sobre la ubicación de una revista en sus distintos cuartiles, la principal razón para determinar su categoría. Aunque semejante proceder echa por la borda un trabajo sostenido de más de 20 años, COLCIENCIAS sigue haciendo oídos sordos a los planteamientos de los académicos. Debido a dicha contingencia, este podría ser el último número de la revista que aparece en la categoría A2, para alcanzar la cual trabajamos incansablemente durante todos estos años cumpliendo al pie de la letra los requisitos establecidos. Resulta aventurado predecir lo que pueda ocurrir con la inestable política de COLCIENCIAS y su efecto sobre las revistas colombianas, así como con el destino de nuestra publicación. Confiamos en que, finalmente, dicha entidad acceda a escuchar a los editores, autores, académicos e instituciones universitarias y logre concertar una política más acorde con las realidades del país y, sobre todo, más ajustada a las especificidades de las revistas dedicadas a la filosofía o las humanidades.

En este artículo me propongo hacer algunos planteamientos sobre la noción de “diversidad” que nos ayuden a situarla en el contexto general de la epistemología y en el particular de las ciencias sociales contemporáneas, sugerir varias estrategias para mejorar nuestra comprensión de algunas discusiones actuales relacionadas con la naturaleza de los múltiples saberes, su estatus epistemológico y sus relaciones y diferencias con la definición clásica de “conocimiento”, examinar el problema de si hay una o varias epistemologías y cuáles son las (...) implicaciones de cada alternativa, ofrecer una caracterización de ciencia empírica (aplicable en el campo de la investigación social) y mostrar sus relaciones con la tesis de la existencia de múltiples saberes. Por último, ofreceré algunos argumentos para ilustrar las razones por las cuáles es preferible usar un enfoque metodológico monista para investigar desde la diversidad. (shrink)

El artículo presenta una propuesta para promover la comprensión de las nociones de posibilidad, necesidad y validez argumental. Por medio de un criterio psicológico, la propuesta busca que los estudiantes capten dichas nociones de forma intuitiva antes de comenzar a usar las pruebas formales de validez. Se muestra cómo puede adaptarse la propuesta en el uso de los diagramas de Venn y en la diagramación de algunas formas silogísticas que la teoría clásica del silogismo considera válidas pero que no aparecen (...) como formas válidas en la diagramación canónica que usa los diagramas de Venn.

According to some authors, Popper’s realism is blatantly incoherent mainly because of his commitment with the correspondence theory of truth and due to the fact that in his theory of cience is granted that, though the general aim of science is the search for truth, it might happen that a specific theory reaches that aim without us being able of knowing it. In this paper, I explain, briefly, the particularities of Popper’s realism, his views on truth as a regulative ideal (...) for science, and I show that, regardless the impossibility of establishing in a efinitive way that truth has been reached, there is no incoherence that endangers his project. In this way, I answer Cardenas and others’ criticisms against Popper’s realism and his views on the general aim of science, and I identify the sources from which this kind of misunderstanding springs.

Some properties and an algorithm for solving systems of multivariate polynomial equations over finite fields are presented. It is then shown how formulas of propositional logics can be translated into polynomials over finite fields in such a way that several logic problems are expressed in terms of algebraic problems. Consequently, algebraic properties and algorithms can be used to solve the algebraically-represented logic problems. The methods described herein combine and generalise those of various previous works.

This article critically examines the domination exerted by big digital companies on the current social, economic, and political context of modern societies, with a particular focus on the implications for the proper functioning of democracy. The objective of this article is to introduce and develop the concept of datafeudalism, expose its emergence for the proper functioning of modern societies and democracy, and to propose courses of action to reverse this situation. To achieve this purpose, firstly, the evolution from surveillance capitalism (...) to datafeudalism will be discussed. Secondly, the structures and operating logic of data feudalism will be analyzed. Thirdly, the harmful impacts of datafeudalism on the proper functioning of the democratic systems of the European Union will be examined. Finally, an attempt will be made to outline courses of action that will make it possible to reverse the situation of economic, social and political tyranny exercised by big digital companies through datafeudalism.

In futsal there are two referees on the playing court and their capacity to respond to physical and physiological demands imposed during the game is essential for the success. The futsal characteristics such as size pitch, referees position and rules of games or type of league could impose specific physical efforts probably. The aim of this study were to analyze the physical demands of eight elite referees from seven matches of Spanish Futsal Cup 2020. The physical activity of each referee (...) during the match was monitored with a Local Positioning System, which was installed on futsal pitch where the matches were played. The data differences were evaluated as Paired-Samples T-Test procedure. The results revealed a similar total distance between halves. The zone 3 distance showed a significative decrease during the match in comparison to the first and second halves. The number of high-intensity acceleration and deceleration decreased in the second half of the match. Therefore, the use of the tracking device to monitoring physical performance provides knowledge of the specific activity profile from futsal referees. This information to can be useful to design more accurate the training programs. (shrink)

ABSTRACT:Ethical research on consumption has focused mainly on the obligations, principles and values guiding consumers' actions and reasons for action. In doing so, it has concerned itself mostly with such bounded contexts as voluntary simplifiers, anti-consumption movements or so-called ‘ethical consumers,’ thereby fostering an artificial opposition between ethical and non-ethical consumption. This paper proposes virtue ethics as a more apt conceptual framework for the ethical analysis of consumption because it takes into account the developmental dynamic triggered by engagement in consumption (...) practices. We build on MacIntyre's goods-virtues-practices-institutions framework and Beabout's concept of a domain-relative practice and argue that when engaging in consumption activities, agents may pursue goods internal to practices, further their individual life narratives and contribute to the good of their communities, thus developing virtues that perfect themselves both as consumers and as ethical agents.

We report three experimental studies of reasoning with double conditionals, i.e. problems based on premises of the form: If A then B. If B then C. where A, B, and C, describe everyday events. We manipulated both the logical structure of the problems, using all four possible arrangements (or ''figures" of their constituents, A, B, and C, and the believability of the two salient conditional conclusions that might follow from them, i.e. If A then C , or If C then (...) A . The experiments showed that with figures for which there was a valid conclusion, the participants more often, and more rapidly, drew the valid conclusion when it was believable than when it was unbelievable. With figures for which there were no valid conclusions, the participants tended to draw whichever of the two conclusions was believable. These results were predicted by the theory that reasoning depends on constructing mental models of the premises. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Violent Conflict, the Struggle for Identity, and the Contagion of Mimetic Desire in the Prison EnvironmentCarlos GarciaMy name is Carlos Garcia. I am 56 years old and a junior class member of the Hope College–Western Theological Seminary Prison Education Program. I have lived my entire life in the state of Michigan. Unfortunately, more than forty of those years have been spent in juvenile detention centers, county jails, rehabilitation (...) centers, reformatories, and prisons. I have been accused, tried, and convicted legitimately, and wrongfully, for just about every crime less than murder. Needless to say, I know a thing or two about violence. As a result, I have embarked on a journey to understand and make use of those things I have learned in the field of mimetic desire to challenge the current system of prison politics. This writing is what I hope will be the first of many steps toward comprehensible prison reform and lasting rehabilitative programing within the Michigan Department of Corrections and beyond.What is it that makes the prison environment such a volatile place? Could it be the nature or character of the kind of men and women that fill its beds? What, then, does this say about the societies from which they came? Societies may have, in fact, played the greatest role in creating who they have come to be. [End Page 95] Could it be that their communities shaped their natures and made them into the kinds of people that many now fear and look at with curious fascination? Who we think we are might surprise us. Furthermore, who we think we "might" be may surprise us even more.This essay attempts to address and answer the question, "What role does mimetic desire play in the prison environment, and what effect might it have on the violence therein?" It also addresses how inmate identity might be shaped. Does the intentional limitation of material, intellectual, social, and spiritual resources that one may have also restrict individuality in a way that creates an environment of sameness? I suggest the answer is a resounding "yes." As such, mimetic desire becomes the driving force behind the violence therein.It is, I argue, this environment of sameness and the disintegration of differences—not the differences, in and of themselves—that ultimately leads to mimetic desire, competition, and rivalry. Often, and to the point, this environment is where winning the rivalry replaces the initial desire for the material, intellectual, or social object as the desired goal.As I unpack and answer the question and argument just offered, it is important that we first understand the premise upon which they have been formulated. Mimesis, mimetic desire, and mimetic theory are rooted in the idea of imitation. Mimesis, in and of itself, is nothing new. It is simply defined as "imitation or mimicry."1 In context of this essay, however, I address mimetic desire more specifically, as it has been theorized by its founder, French professor of history and literature René Girard. Luke Burgis, the author of Wanting: Mimetic Desire in Everyday Life, defines mimesis as "A sophisticated form of imitation that in adults is usually hidden. In mimetic theory, mimesis has a negative connotation because it usually leads to rivalry and conflict."2 Mimetic desire is defined as "Desire generated and formed through the imitation of what someone else has already desired."3 This means that what we want or desire is what the other—someone we might consider to be a model or mediator—wants, or desires, not necessarily because of the intrinsic value of the object, but because of the value we perceive the other's desire has placed on it. Again, it is mimetic desire sitting at the center of most conflicts and of the struggle for identity (i.e., autonomy) that I believe makes the prison environments volatile.We, as a species, struggle to find our place in the world. Each of us is trying to create our own identities, individually, culturally, collectively, even nationally. In very few places is the struggle more real, or its potentially violent consequences more severe, than in the prison environment. The identities of most inmates have been lost or stripped...

Resumen: El propósito de este artículo consiste en responder afirmativamente a la pregunta por la posibilidad de la objetividad en las ciencias humanas. Se comienza planteando que, pese a su aparente anacronismo, la discusión sobre la objetividad se torna vigente frente al desafío que plantea a la epistemología la noción de posverdad. Posteriormente, se reconstruyen algunas versiones de objetividad presentes en la literatura. A continuación, se exponen y discuten algunas posturas respecto a la posibilidad de la objetividad en las ciencias (...) humanas y se evalúa no solo su consistencia, sino también las consecuencias que estas tienen para las ciencias humanas. Finalmente, se proponen algunas ideas para la constitución de un concepto plausible de objetividad para las ciencias humanas. Se espera que este trabajo abra rutas para la exploración sistemática de un programa de epistemología de las ciencias humanas comprometido con un marco realista de investigación.: This paper aims to answer affirmatively the question about the possibility of objectivity in the human sciences. I firstly claim that, though their seemly anachronism, the discussion on objectivity is valid in front of the challenge that puts the notion of post-truth to epistemology. Then, I reconstruct some views about objectivity from the literature. Next, I show and discuss some views about the possibility of the objectivity in the human sciences and I assess both their consistency as the consequences that they have to the human sciences. Finally, I propose some ideas for the constitution of a plausible concept of objectivity for the human sciences. I hope this paper open routes to the systematic exploration of an epistemological program for the human sciences committed with a realistic framework of research. (shrink)

Resumen Este artículo se propone identificar los aspectos básicos de la tesis de Emmanuel Levinas sobre la dimensión ética de la significación. En un primer momen to, se reconstruyen las críticas del autor a dos aproximaciones a la significación, denominadas en este trabajo: el ámbito de los signos y el ámbito de la expresión. En un segundo momento, se enuncia la tesis de Levinas, según la cual, es en el terreno ético donde la significación encuentra su sentido original. Finalmente, se (...) identifican algunas posibilidades que abre esta consideración levinasiana de la significación para discusiones sobre la percepción, la crisis contemporánea del sentido y la epistemología. Más que una exposición detallada de la teoría levinasiana de la significación, se apuesta por señalar otros cauces de reflexión que partan de su ética como filosofía primera, sin estancarse en ella.This article aims to identify the basic aspects of Emmanuel Levinas’ thesis on the ethical dimensión of significance. At first, the author’s criticisms of two approaches to signification, called in this work: the sphere of signs and the sphere of expression, are reconstructed. In the second moment, Levinas’ thesis is stated, according to which, it is in the ethical field where the meaning finds its original meaning. Finally, some possibilities are identified that this Levinasian consideration of meaning opens up for discussions on perception, the contemporary crisis of meaningg, and epistemology. Rather than a detailed exposition of the Levinasian theory of signification, we will point out other channels of reflection based on its ethics as a first philosophy, without getting bogged down in it.

In “Datafeudalism: The Domination of Modern Societies by Big Tech Companies” (Saura García in Phil Technol 37(3):1–18, 2024a) I analysed the concept of datafeudalism and its implications for the proper functioning of democracy. In this article, I put forward the hypothesis that big digital companies are exercising domination over the current social context and its different functional spheres, such as politics and democracy, and critique the negative implications that datafeudalism is having for the proper functioning of modern democratic systems. (...) In this regard, Wörsdörfer (Phil Technol 37(3):1–5, 2024) has offered a critical commentary on the content in question. In particular, he focuses his discourse on the concept of the digital panopticon and its link with datafeudalism. The following replay present a reasoned response to these questions. (shrink)

Corporate social responsibility pedagogies and teaching techniques have been extensively discussed in the literature. They are viewed as crucial for illustrating business–society relationships and encouraging business students to act ethically. Although the experiential learning perspective prevails in the discussions on CSR education, little attention has been paid to the discursive nature of CSR learning. Considering this gap, the paper explores the role of discourses in CSR education by drawing upon the discursive perspective on CSR and the relational social-constructionist orientation to (...) management learning. To that end, a story co-creation exercise implemented in a CSR course in a Nordic University is used to demonstrate how discourses enable and constrain certain CSR meanings within a business educational context. The paper contributes to the field of CSR education and critical CSR research by suggesting how the discursive nature of CSR can be used to promote more reflexive practices among business students.

Attention is also paid to what information can be gathered from the approximation degree of economic theoretical models about what may finally happen in the corresponding empirical situations, and to the ways by which this information can be increased. Some comments about the applicability of approximation comparisons are added. (shrink)

Education is a fundamental pillar in human development, and its evolution throughout history has been influenced by a variety of factors, including imaginative culture and human nature. In this study, we explore how educational methods have evolved in response to the interaction between these two aspects. We look at how human creativity, imagination, and adaptation have influenced the way we teach and learn, from early forms of knowledge transmission to more contemporary approaches focused on active student engagement and the development (...) of practical skills. Our research is based on a comprehensive review of the academic literature in the fields of education, evolutionary psychology, cultural anthropology, and imagination studies. We explore how societies have used imagination as a tool to transmit knowledge and values, as well as to foster creativity and individual expression. We also examine how adaptive aspects of human nature, such as the ability to learn collaboratively and adapt to changing environments, have influenced the way educational methods are designed. Our results show a clear evolution in educational methods over time, from approaches focused on the one-way transmission of knowledge to more interactive and participatory models that encourage exploration and discovery. We identify common patterns in the way societies have used imagination and adaptation to promote learning and socialization and discuss the implications of these findings for contemporary education. In conclusion, this study highlights the importance of understanding the relationship between imaginative culture, human nature, and education. It provides a solid foundation for the design of educational methods that harness the innate creativity and adaptability of human beings and offers guidance for educators and policymakers on how to promote meaningful and lasting learning in today's world.
