Este artículo presenta una investigación cualitativa sobre los conceptos de Hermenéutica e ironía desde la revisión del texto rortiano Contingencia, ironía y solidaridad. A través de un recorrido por la Historia de la razón filosófica se muestra cómo el compromiso hermenéutico con el mundo está atravesado por las ideas de solidaridad y contingencia. Finalmente, se propone una lectura del círculo hermenéutico como reivindicación de una sociedad preocupada por la justicia que reconoce la carencia de todo amparo metafísico.

La Unión de Consumidores de España (UCE) es una asociación sin ánimo de lucro fundada en el año 1984 gracias a la integración en una misma institución de las diferentes asociaciones de consumidores de ámbito regional y local. UCE, al igual que otras asociaciones de consumidores, nace en plena transición al amparo de lo establecido en los artículos 22 y 23 de la Constitución Española.

El debate que se gestó alrededor del concepto de existencia en manos de Willard Van Orman Quine y Rudolf Carnap, dio al siglo XX un cúmulo de aportes significativos a la ontología. La postura realista, con algunas variantes, de Quine y el criterio anti-realista de Carnap, otorga insumos para pensar de mejor forma cómo se intenta dar descripciones acerca del inmobiliario del mundo. Conocer este debate es importante, ya que, se expone los alcances y limitaciones que implican las explicaciones ontológicas (...) acerca de la realidad que deben ser tenidas en cuenta en la actualidad. Este trabajo cumple esa función, la de explicar sintéticamente uno de los debates más importantes para la ontología. (shrink)

Justo antes de la pandemia por COVID-19, la Organización Mundial de la Salud definió unas prioridades de trabajo para la década 2020-2030. Un grupo interdisciplinario de profesionales de la salud reflexiona sobre estas prioridades, determinando unas categorías de análisis y, desde una perspectiva bioética, analiza cada una de ellas, ve su pertinencia, algunos eventos causales, las implicaciones que pueden tener si no son enfrentadas adecuadamente y hace sugerencias sobre la forma de llevarlas a cabo. En esta primera entrega se analiza (...) el primer grupo de prioridades estratégicas: “poblaciones más sanas”. En las conclusiones se destaca la conveniencia de acometer cada una de ellas de una manera colaborativa, gubernamental y privada; de reestructurar el sector salud con base en estas prioridades, aprovechando la experiencia obtenida en la lucha contra el COVID-19. La relación del ser humano con el medio ambiente también debe cambiar, apelando a la responsabilidad humana por el cuidado del planeta. (shrink)

Electricity is an indicator that shows the progress of a civilization; it is a product that has greatly changed the way we think about the world. Electricity price forecasting became a fundamental task in all countries due to the deregulation of the electricity market in the 1990s. This work examines the effectiveness of using multiple variables for price prediction given the large number of factors that could influence the price of the electricity market. The tests were carried out over four (...) periods using data from Spain and deep learning models. Two different attribute selection methods based on Pearson’s correlation coefficient have been used to improve the efficiency of the training process. The variables used as input to the different prediction models were chosen, considering those most commonly used previously in the literature. This study attempts to test whether using time series lags improves the non-use of lags. The results obtained have shown that lags improve the results compared to a previous work in which no lags were used. (shrink)

Legislation on Disability/ Functional Diversity in Spain has experimented a great advance since 1982 to 2013, leaving the initial orientation, based on care and rehabilitation, toward another one based on rights and social inclusion as main objectives. However, this legislation has not been effective because in the same lap of time another transformation made it useless: the suppression of social rights that came from Keynesian politics and the progressive neoliberal ideology implantation. The evolution of People with Disability/ Functional Diversity labour (...) situation illustrates the imposition of what we name neoliberal “ableisment” over PFD labour rights. (shrink)

Vico no sólo reabre en la modernidad la contienda por la verdad, sino que emerge de nuevo en el discurso actual de la posmodernidad recordándonos la muerte del precario concepto insular del hombre centrado en la razón científica, de una racionalidad incompleta. Existe una deuda de la modernidad hacia la epistemología genética y la hermenéutica de la Scienza Nuova: que considera la poesia un modo de acceso a la verdad y aprecia en las ficciones poéticas el caracter de verdades. Esta (...) cuestión resulta determinante para apreciar la polérnica abierta entre modernidad y posmodernidad centrada en un replanteamiento dilucidador de la razón. En la búsqueda de una fundarnentación de la razón desde ella misma, la razón poética abre nuevas perspectivas y reconocidas posibilidades.Vico does not only reopen in the Modernity the dispute for the truth, but emerges again in today's discourse of the Postmodernism, reminding us of the dearth of the precarious insular concept of man centered in the scientific reason, of an incomplete rationality. There is a debt of Modernity towards the genetic epistemology and the hermeneutic of the New science that considers poetry a way of access to the truth and recognizes in poetical fictions the nature of truths. This subject becomes decisive to appreciate the open controversy betwen Modernity and Postmodernism, centered in an explanatory restatement of the reason. In the search of a foundation of the reason from itself the poetical reason opens new perspectlves and acknowledged possibilities. (shrink)

Vico delineó desde la "fantasia" la forma de aproximación al fenómeno estético y al hecho artístico, y de él procede, en gran parte, el actual revival de la hermenéutica en diversos campos del pensamiento, de la crítica y de las artes. El presente trabajo indaga dos aspectos importantes en la cultura de los siglos XVII y XVIII: en primer lugar la reflexión y discusión sobre los principios estéticos, enfatizados en la querelle des anciens et des modernes ; y en segundo (...) lugar, el descubrimiento del sentimiento y el rescate de la imaginación.Vico laid out from the notion of "fantasia" the way to be approached to the aesthetic phenomena and to the artistical fact. A great deal of the present revival of hermeneutics within the great variety of fields such as literary criticism, arts or general thought may be traced back to his foremost contributions. This paper focuses on two important aspects within the XVII and XVIII century cultural frame: one, the reflections and debates about the aesthetic principles as they were purported in the querelle des anciens et des modernes ; and the other, the finding of sentiment and the rescue of imagination.

La Constitución dogmática Lumen gentium ha rescatado desde la tradición cristiana la expresión Iglesia doméstica para referirse a la familia. Dicha expresión posee en sí misma una riqueza incalculable al momento de descubrir el misterio de la esencia y misión de la familia cristiana, por lo que aporta elementos fundamentales para la elaboración de una teología de la familia. Es por este motivo que la presente investigación pretende levantar una propuesta de lectura eclesiológica de la Iglesia doméstica, a partir de (...) cuatro claves de lectura: cristológica, sacramental, pneumatológica y escatológica. The dogmatic Constitution Lumen gentium has rescued from Christian tradition, the expression Domestic Church referred to the family. Such expression possess in itself an invaluable richness considering that discovers the essence and the mission of Christian family. That´s why it contributes with fundamental matters to the elaboration of a Theology of the Family. For this reason, this research pretends to raise a proposal of ecclesiological reading of Domestic Church, based in four key reading points: Christological, sacramental, pneumatological and eschatological.

We consider the first-order finite-difference expression of the commutator between d / dx and x. This is the appropriate setting in which to propose commutators and time operators for a quantum system with an arbitrary potential function and a discrete energy spectrum. The resulting commutators are identified as universal lowering and raising operators. We also find time operators which are finite-difference derivations with respect to the energy. The matrix elements of the commutator in the energy representation are analyzed, and we (...) find consistency with the equality \. We apply the theory to the particle in an infinite well and for the Harmonic oscillator as examples. (shrink)

The enthymeme is essential because it reflects what humans do when they think. It provides an effective pedagogical approach to the analysis and synthesis of ideas in the classroom. In this volume, such an approach is applied to various areas of content for the purpose of helping students prepare themselves for the challenges of modern life.

This paper deals with the equilibria of games when the agents have multiple objectives and, therefore, their utilities cannot be represented by a single value, but by a vector containing the various dimensions of the utility. Our approach allows the incorporation of partial information about the preferences of the agents into the model, and permits the identification of the set of equilibria in accordance with this information. We also propose an additional conservative criterion which can be applied in this framework (...) in order to predict the results of interaction. The potential application of the theoretical results is shown with an analysis of a mixed oligopoly in which the agents value additional objectives other than their own benefit. These objectives are related to social welfare and to the profit of the industry. The flexibility of our approach provides a general theoretical framework for the analysis of a wide range of strategic economic models. (shrink)

Digital photography is contributing to the renegotiation of the public and private divide and to the transformation of privacy and intimacy, especially with the convergence of digital cameras, mobile phones, and web sites. This convergence contributes to the redefinition of public and private and to the transformation of their boundaries, which have always been subject to historical and geographical change. Taking pictures or filming videos of strangers in public places and showing them in webs like Flickr or YouTube, or making (...) self-portraits available to strangers in instant messenger, social network sites, or photo blogs are becoming a current practice for a growing number of Internet users. Both are examples of the intertwining of online and offline practices, experiences, and meanings that challenge the traditional concepts of the public and the private. Uses of digital images play a role in the way people perform being a stranger and in the way they relate to strangers, online and offline. The mere claims about the privatization of the public space or the public disclosure of intimacy do not account for all these practices, situations, and attitudes, as they are not a simple translation of behaviors and codes from one realm to the other.

In the business ethics literature, the growing interest in social entrepreneurship has remained limited to the assumption that pursuing a social mission will clash against the pursuit of associated economic achievements. This ignores recent developments in the social entrepreneurship literature which show that social missions and economic achievement can also have a mutually constitutive relation. We address this gap adopting the notion of shared value for an ethical inquiry of social entrepreneurship. Using a sensemaking framework, we assume that the emergence (...) of SV propositions can be captured through the analysis of how social entrepreneurs make sense of events of change, selecting the journey of three exemplar cases for an inductive empirical inquiry. From our findings, we propose three themes for further examination. First, the ethical groundings of entrepreneurial SV are mostly shaped by idiosyncratic imperatives that inform both social mission and economic gain from the onset. Second, the ethical groundings of entrepreneurial SV will be likely operationalised as a filtering device, which allows for resilience as well as potentially detrimental blind spots. And third, the ethical groundings of entrepreneurial SV are expressed through ongoing transparency. Whilst there are agendas, these are not necessarily hidden but instead are likely put on show for the scrutiny of markets and communities. We hope that this evidence can add more light to our still modest understanding of the ethical groundings of social entrepreneurship. (shrink)

El «mundo entero» vive un gran desasosiego al estar inmiscuido en la dominación de la Naturaleza sustentada en la gran inversión económica, desde el paradigma antropocéntrico neoliberal. El objetivo del presente trabajo es reconocer y abrazar epistemologías y metodologías alternativas, entre ellas validar las contribuciones de los pueblos indígenas (PI) como protagonistas de la sustentabilidad y soberanía alimentaria. La investigación es de corte documental y la reflexión personal de más de 20 años de labor junto a los PI en Mesoamérica (...) y los Andes. Valorar dichas contribuciones, es centrarse en sus acervos y corpus cognoscitivos, antes que sea tarde. Son los sabios guardianes de la sustentabilidad biocultural de la Naturaleza y la Vida. Se concluye principalmente que son quienes conocen las claves, llaves y secretos que dan respuesta al reto de estelarizar la sustentabilidad y seguridad alimentaria global, que tanto persigue la humanidad. La sociedad en general y en particular las instancias oficiales, formativas, políticas, corporativas, industriales, de extensión y académicas, deben distinguir a estos actores sociales que soportan hoy la seguridad alimentaria mundial. El hallazgo principal cual severa advertencia, es que al «desaparecer» estaríamos ante un fenómeno descomunal de inseguridad alimentaria mundial. (shrink)

Cette étude, à partir du cas colombien, présente une théorie globale novatrice du trafic des drogues, qu'elle présente comme le symptôme de la situation générale de l'homme contemporain confronté aux problèmes de la mondialisation. Elle pose ainsi le problème du trafic des drogues comme la rencontre entre des subjectivités et les productions des grands systèmes économiques, politiques et juridiques, dans une perspective sociale et anthropologique critique.

This article builds on the notion of legal tolerance and analyzes the scope of its definition. It situates the notion in the complex set of relations occurring between the major systems of society. Generally, legal tolerance, as a concept, is understood in light of the possibilities of the legal system of influencing other major systems? responses. On the other hand, tolerance is also the response of the legal system in respect to other major systems? communications. Although there is a common (...) understanding of tolerance as ?under punishing bias? in criminology or as political tolerance in political science, 1 the focus of this article is different. The central points here are, first, the analysis of legal tolerance as part of systemic communications and, second, the historicity of the transformations of the nation-state in its ability to cope with the growth of separate, distinct and partial systems of society. Tolerance seems relational and raises questions such as: ?How much can the legal system tolerate?? And also, ?Which societal topics belong to the social system's domain-matter?? These questions are relevant given that the concept of legal tolerance depends on the possibilities of a given system to steer, to direct or to influence other major systems? behavior, or to resist, respond or to address other systems, which are in its environment. The concept of legal tolerance requires an analysis of a cluster of related definitions to assess the implications of the concept. These definitions are the following: (1) The concepts that result from the historical process of structuration and that explain the emergence of social systems. (2) The definition of reflexivity and its relation with the ?second order cybernetics dilemma.? This is the place where heuristic and epistemological problems are found. Such problems result from both the problem of representation and from the ontological status of the real. This analysis will show why reflexivity is a key concept to explaining the transformations suffered by such systems. Then, legal tolerance is a newer development in respect to the idea of planning. As an alternative to hard planning, legal tolerance creates a fostering environment. Instead of a single system directing other systems, legal tolerance is relational and created collectively by the organizational national state using its (limited) power of legal creation. Legal tolerance also stems from the concerned subsystems of the society (economy, law, politics, science, along with others) by means of a variety of legislative products, public policies, alliances, and legal and other scientific communications that emerge as coordinating mechanisms among the alluded major subsystems.

Peer review is a widely accepted instrument for raising the quality of science. Peer review limits the enormous unstructured influx of information and the sheer amount of dubious data, which in its absence would plunge science into chaos. In particular, peer review offers the benefit of eliminating papers that suffer from poor craftsmanship or methodological shortcomings, especially in the experimental sciences. However, we believe that peer review is not always appropriate for the evaluation of controversial hypothetical science. We argue that (...) the process of peer review can be prone to bias towards ideas that affirm the prior convictions of reviewers and against innovation and radical new ideas. Innovative hypotheses are thus highly vulnerable to being “filtered out” or made to accord with conventional wisdom by the peer review process. Consequently, having introduced peer review, the Elsevier journal Medical Hypotheses may be unable to continue its tradition as a radical journal allowing discussion of improbable or unconventional ideas. Hence we conclude by asking the publisher to consider re-introducing the system of editorial review to Medical Hypotheses. (shrink)

El presente artículo tiene lugar a partir de un estudio de caso autoetnográfico basado en experiencia de acoso laboral de la autora en una universidad española. El objetivo central del trabajo es examinar, desde un abordaje de ética aplicada, la compleja trama de poder en la que emergen y se desarrollan prácticas de violencia y acoso laboral en instituciones académicas y universitarias. Frente a los dispositivos que facilitan la perpetuación de estas prácticas de violencia y exclusión, así como su naturalización, (...) el artículo propone revisitarlas a la luz de los criterios de las éticas organizacionales y los liderazgos morales, en aras de enriquecer las herramientas ya existentes en distintas universidades para detectar acoso y promover éticas colectivas. El artículo argumenta la necesidad de potenciar las estrategias multimodales contra el acoso laboral en la academia, a fin de que realmente sean efectivas y no parte de protocolos meramente formales. Finalmente, se propone apelar a una profunda crítica desde la ética filosófica en torno a los discursos y prácticas de acoso laboral académico y universitario, para erradicar las violencias no sólo en estas instituciones sino en cualquier ámbito de la vida social. ABSTRACT This article arises from an autoethnographic case study based on the author’s experience of harassment at work in a Spanish university. The main objective is to examine from an approach of applied ethics, the complex web of power in which emerge and develop practices of violence and harassment in academic and university institutions. Against the dispositive that facilitate the perpetuation of these practices of violence and exclusion, as well as their naturalization; the article proposes to revisit them in the light of the criteria of organizational ethics and moral leaderships, to enrich the tools already existing in different universities to detect mobbing and promote collective ethics of others. The article shows and argues the need to strengthen and radicalize the multimodal strategies to eradicate mobbing in the academy and the university so that they are effective and not part of merely formal protocols. Finally, it proposes to appeal to a deep criticism from the philosophy and ethics around the speeches and practices of academic and university mobbing to eradicate violence not only in these institutions but in any area of social life.

Resumen En el siguiente artículo se pretende hacer una lectura teológica del poder siguiendo a Karl Rahner en su concepción del mismo como don, tarea y posibilidad. El poder es don divino para el ser humano el cual participa del poder de Dios, sin embargo, cuando lo ejerce puede corromperse y pierde la finalidad para lo que es entregado. De este modo, el mal ejercicio del poder tiene repercusiones tanto para la persona como para la sociedad, graves consecuencias, por eso (...) es necesario asumir la responsabilidad de cada acción. En este sentido, el ejercicio del poder es una tarea esencial para la vida en sociedad y, a la vez, es una posibilidad de construcción del Reino con alcances escatológicos. Abtracts The following article intends to make a theological reading of power following Karl Rahner in his conception of it as a gift, task and possibility. Power is a divine gift for the human being who participates in the power of God, however when exercised it can be corrupted and loses the purpose for what is delivered. In this way, the bad exercise of power has repercussions for both the person and society, serious consequences, that is why it is necessary to take responsibility for each action. In this sense, the exercise of power is an essential task for life in society and at the same time, it is a possibility of building the Kingdom with eschatological scope. (shrink)

Desde finales del siglo XX, las investigaciones sobre modernidad, orientadas hacia distintos segmentos del campo cultural, han venido ganando un enorme terreno. Las obras de Walter Benjamin, leídas en esta perspectiva, cobran un gran valor. Se busca explorar cuatro temas benjaminianos: a) algunos aspectos de su concepto de historia; b) el concepto de experiencia, para mostrar su dimensión histórico-crítica con respecto al ascenso de la cultura moderna; c) las afinidades entre el modo en que se desarrolla la visión alegórica en (...) el drama barroco alemán y el modo en que Baudelaire afronta las problemáticas de la modernidad; d) elementos de algunas formas culturales del arte moderno que entusiasman a Benjamin.

Cet article propose une nouvelle lecture de l’utopie et de l’éthique de notre ère planétaire, s’inspirant des principes de « terre-patrie » d’Edgar Morin, qui suggèrent une autre vision de notre état du monde. La validité et la pertinence du concept de « terre-patrie » émergent comme une alternative à l’heure où nos visions du monde basculent fortement vers le désespoir et où celui qui dépeint un avenir utopique s’expose à la moquerie.

Abductive problems and their solutions are presented by means of justification logic. We introduce additional meta-constructions in order to generate and compare different solutions to the same abductive problem. Our approach has three advantages: (i) it makes structurally explicit the solution to an abductive problem (as it has a syntactic nature); (ii) it gives a precise meaning to the notion of evidence; (iii) it provides clear definitions and procedures for the comparison of solutions that can be adapted to different needs.

Recent developments in pattern analysis research have made this methodology suitable for the study of the processes that are set in motion in psychological interventions. Outcome research, based on the comparison between clinical results from treatment and control groups, has leveraged our empirical knowledge about the efficacy of psychological interventions. However, these methods of research are not precise enough for the analysis of these processes. On the contrary, pattern analysis could be a powerful tool to study moment-to-moment interactions typical of (...) psychological interventions. This is methodology is relevant because clinical psychology is experiencing a paradigm shift from a protocol for syndrome perspective to a principle-based and person-centered intervention. This evidence-based, theory-grounded, and process-oriented paradigm of clinical intervention needs new research methods to thrive. The analysis of the therapeutic relationship built into the verbal interaction between the clinician and the client is one of the cornerstones of this new era of research. So, the purpose of this article is three-fold: to discuss the role of the verbal interaction pattern analysis in the clinical context to the development of the principle-based clinical psychology, to analyze the patterns of verbal interaction in a clinical case, and to compare the results using two different methods. To reach these purposes, using the observational methodology, we have coded the verbal interaction of 16 clinical sessions with a person diagnosed with a borderline personality disorder. We have analyzed the data using sequential analysis and pattern recognition algorithms. We have been able to detect typical patterns during different phases of psychological intervention. Finally, the conceptual, methodological, and empirical implications of this study will be discussed within the realms of pattern analysis research and principle-based clinical psychology. (shrink)

Cognitive scientists have a variety of approaches to studying cognition: experimental psychology, computer science, robotics, neuroscience, educational psychology, philosophy of mind, and psycholinguistics, to name but a few. In addition, they also differ in their approaches to cognition - some of them consider that the mind works basically like a computer, involving programs composed of abstract, amodal, and arbitrary symbols. Others claim that cognition is embodied - that is, symbols must be grounded on perceptual, motoric, and emotional experience. The existence (...) of such different approaches has consequences when dealing with practical issues such as understanding brain disorders, designing artificial intelligence programs and robots, improving psychotherapy, or designing instructional programs. The symbolist and embodiment camps seldom engage in any kind of debate to clarify their differences. This book is the first attempt to do so. It brings together a team of outstanding scientists, adopting symbolist and embodied viewpoints, in an attempt to understand how the mind works and the nature of linguistic meaning. As well as being interdisciplinary, all authors have made an attempt to find solutions to substantial issues beyond specific vocabularies and techniques. (shrink)
