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)

We report five experiments showing that the activation of the end-terms of a syllogism is determined by their position in the composite model of the premises. We show that it is not determined by the position of the terms in the rule being applied (Ford, 1994), by the syntactic role of the terms in the premises (Polk & Newell, 1995; Wetherick & Gilhooly, 1990), by the type of conclusion (Chater & Oaksford, 1999), or by the terms from the source premise (...) (Stenning & Yule, 1997). In our first experiment we found that after reading a categorical premise, the most active term is the last term in the premise. In Experiments 2, 3, and 4 we demonstrated that this pattern of activity is due to the position of the concepts in the model of the premises, regardless of the delay after reading the premises (150 or 2000 msec) or the quantity of the quantifiers (universal or existential). The fifth experiment showed that the pattern switches around after participants evaluate a conclusion. We propose that the last element in the model maintains a higher level of activity during the comprehension process because it is generally used to attach the incoming information. After this process, the first term becomes more active because it is the concept to which the whole representation is referred. These results are predicted by the mental model theory (Johnson-Laird & Byrne, 1991), but not by the verbal reasoning theory (Polk & Newell, 1995), the graphical methods theory (Yule & Stenning, 1992), the attachment-heuristic theory (Chater & Oaksford, 1999), or the mental rules theory (Ford, 1994).

The area of smart power grids needs to constantly improve its efficiency and resilience, to provide high quality electrical power in a resilient grid, while managing faults and avoiding failures. Achieving this requires high component reliability, adequate maintenance, and a studied failure occurrence. Correct system operation involves those activities and novel methodologies to detect, classify, and isolate faults and failures and model and simulate processes with predictive algorithms and analytics. In this paper, we showcase the application of a complex-adaptive, self-organizing (...) modeling method, and Probabilistic Boolean Networks, as a way towards the understanding of the dynamics of smart grid devices, and to model and characterize their behavior. This work demonstrates that PBNs are equivalent to the standard Reinforcement Learning Cycle, in which the agent/model has an interaction with its environment and receives feedback from it in the form of a reward signal. Different reward structures were created to characterize preferred behavior. This information can be used to guide the PBN to avoid fault conditions and failures. (shrink)

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.

Resumen: Este trabajo se propone revisar la tesis de la proliferación de alternativas, expuesta por Boaventura de Sousa Santos, a la luz de algunas críticas a la tesis de la proliferación de teorías, expuesta por Paul Feyerabend. Se defiende que, aunque no de modo explícito, hay una afinidad entre ambas tesis y, en consecuencia, las debilidades de la segunda afectan a la primera. No obstante, el objetivo básico consiste en mostrar cómo propuestas emergentes, como la ecología de los saberes, antes (...) que insistir en su carácter contraepistemológico, podrían beneficiarse de una discusión epistemológica amplia.: In this paper I review the thesis about the proliferation of alternatives by Boaventura de Sousa Santos, from some criticisms to the thesis of the proliferation of theories by Paul Feyerabend. I claim that, though not in explicit way, there is an affinity between them, therefore the weakness from the second one affects the first one. However, the point is to show how some emergent proposals, as the ecology of knowledges, could benefit from a full epistemological discussion, instead of insisting on its counter-epistemological nature.

En la obra dramática A puerta cerrada (1944), el filósofo y literato Jean-Paul Sartre plantea la relación interpersonal como plena de conflicto e imposibilidad para llevar a cabalidad los ideales dialógicos. Las conclusiones a las que llega Sartre serán confrontadas con la propuesta del filósofo judío Emmanuel Levinas, con el fin de vislumbrar sus tesis en torno a la alteridad, mostrando cómo, en vez de acuerdos racionales que superen lo diverso y lo engloben en la totalidad, habrá que recibir al (...) Otro y responderle en la trascendencia que exige su infinitud. The Philosopher and Writer Jean-Paul Sartre, in the dramatic work No Exit (1944), claims the inter-subjective relationship is full of conflict and that it is impossible to reach the dialogical ideal. We will confront Sartre´s conclusions from the proposal of the jewish philosopher Emmanuel Levinas in order to see his thesis about otherness. We will explain how, instead of some rational agreements that overcome the diversity inside totality, it is necessary to receive the other and respond to him in the transcendence that Infinity requires.

O presente artigo se propõe a confrontar uma leitura antirrealista da obra do fenomenólogo Edmund Husserl e a sugerir que ela pode ser interpretada mais adequadamente como marco do realismo científico. Para tanto, primeiramente, será exposto um dos mais recentes e elaborados projetos nos quais Husserl se relaciona ao Empirismo Construtivo de Van Fraassen. Posteriormente, serão assinaladas as dificuldades encontradas para interpretar algumas teses de Husserl desde o marco antirrealista, enfocando, principalmente, a discussão sobre os inobserváveis, mostrando como a sua (...) existência não é uma tese indiferente à fenomenologia husserliana. Por fim, será indicado como Husserl poderia estar mais próximo do marco realista. In this paper I confront an anti-realistic approach to Edmund Husserl's Phenomenological work and I suggest that this work could most suitably constitute into the Scientific Realistic framework. In order to this, I will first show one of most recent and elaborate claims which relates Husserl with Van Fraassen's Constructive Empiricism. Later, I will point out some existing difficulties to interpret the Husserlian thesis using the anti-realist framework. I will specially focus on the discussion about unobservable entities, arguing how the existence of the unobservable is not an alien thesis to the Phenomenology of Husserl. Finally, I will point out how Husserl is closer to the Realistic framework. (shrink)

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.

The Thesis of Theory-Laden [TTL] holds that is not possible a neutral observation. From this thesis, some philosophers have inferred that the facts, i.e., the subject’s independent reality, do not exist or that they are social constructions only. The aim of this paper is assess if TTL necessarily implies a constructivist point of view or if, conversely, we can still speak about the reality. In order to do this, we will clarify these terms: "the theory-ladenness of observation" and "constructivism". Then, (...) we will argue that although TTL is possible, we are not committed to constructivism, and on the contrary, TTL can be an interesting frame to the realistic thesis. Finally, we will point out the impact this had has when evaluating many epistemological proposals. La tesis de la carga teórica de la observación [CTO] sostiene que no es posible una observación neutral. A partir de esta tesis, algunos filósofos han derivado que los hechos, o mejor, la realidad independiente del sujeto, no existen o que son solo construcciones sociales. El objetivo de este artículo es evaluar si CTO implica necesariamente una visión constructivista o si, por el contrario, permite seguir hablando de realidad. Para ello, se aclararán los conceptos de "carga teórica de la observación" y de "constructivismo". Posteriormente, se defenderá que pese a la plausibilidad de CTO, no estamos comprometidos a adoptar el constructivismo, antes bien, CTO puede ser un interesante marco para las tesis realistas. Finalmente, se señalarán algunas repercusiones que esto tiene a la hora de evaluar propuestas epistemológicas. (shrink)

This article sets out a global analysis of the weaknesses, threats, strengths and opportunities that define the current situation of nursing in Europe. The nursing profession in Europe is suffering from a crisis of self‐efficacy with the syndrome of burnout being one of its consequences. Other weaknesses include shortage of staff, job insecurity, devalued nursing image in society and the lack of recognition of emotional and psychological dimensions of care. The threats to this profession are linked to the lack of (...) prestige and social recognition and to the current economic crisis in Europe. The European economic crisis favours staff shortages and increased European migration flow. The strength of the group lies in the art of caring, which is its defining feature. Primary Care Nursing and Hospital Liaison Nursing demonstrate the great professional adaptability in meeting the needs of the ever‐changing society. The European Higher Education Area and the strengthening of the specialties provide opportunities for the nursing profession. Both represent an important progress towards solid professionalism that will give nursing greater visibility. Moreover, nursing must implement strategies to disseminate its activity and emerge from anonymity. Nursing must show society the image it wants to project. (shrink)

The aim of the present study was to determine statistical differences in a set of badminton competition matches in five different modalities with regard to competition level (Group Phase versus Eliminatory Phase). Data from 453 sets (125 in men’s singles; 108 sets in women’s singles; 77 sets in men’s doubles; 73 in women’s doubles and 70 in mixed doubles) from the RIO 2016 Olympics Games were recorded and classified in two groups of variables to analyse variables related to match (5) (...) and set (15). A descriptive analysis and univariate test (Mann Whitney U) for non-parametric data were conducted. The results show in men’s and women’s singles all the variables related to match were higher in the Elimination Phase than in the Group Phase (p<0.01). In Sets 1 and 3, the longest set duration, rally and average rally were found in the Elimination Phase than Group Stage (p<0.05). In women’s singles, these differences were also recorded in Set 2. For doubles, the results are more stable among groups. Men’s doubles had a longer duration of the match and set (set 1 and set 2) (p<0.01), and also scored highest for average rally strokes (set 1 and set 3) (p<0.05) and shuttles used in the Elimination Phase versus the Group Phase along the match (p<0.01). In women’s doubles, more shuttles were used in a match in the Elimination than in the Group Phase. Moreover, the same results are established for Set 2, including for average rally. Mixed doubles saw no match going to three sets. However, the greatest differences showed a longer rally and average rally being registered in the Elimination than in the Group Phase. In conclusion, the timing factors of the badminton singles and doubles games were different in the Elimination and Group Phases. This information may help players and coaches prepare and administer different types of workouts or, more specifically, competition schedules adapted to the characteristics of modern badminton.

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.

En el artículo se caracteriza una clase de relaciones binarias para que éstas puedan representar las comparaciones de enunciados que un agente puede plantear y resolver de acuerdo con su mayor o menor grado de aproximación a la verdad. Con ello se espera poder analizar con mayor detalle el peso que puede terminar teniendo en su evaluación metodológica el grado de aproximación a la verdad de los modelos teórico-económicos. De todas formas, el propósito inmediato del artículo es el de ofrecer (...) una propuesta más general y, sobre todo, mucho más sencilla que las presentadas en otros dos trabajos anteriores del autor. Por otra parte, el concepto de aproximación a la verdad que se maneja es diferente del vinculado con la noción poperiana de verosimilitud.In this paper, we characterize a class of binary relations to represent the comparisons which an agent can make between statements according to their degree of approximation to the truth. This class of relations, we hope, can help to analyse how much can weight the degree of approximation of economic theoretical models in their methodological assesment. In any case, the immediate purpose of the paper is to offer a proposal easier and more general than two other worked up earlier by the author. On the other hand, our concept of approximation to the truth differs from that linked with the popperian notion of verosimilitude. (shrink)

The amount of information that can be transmitted through a noisy channel is affected by relativistic effects. Under the presence of a fixed noise at the receiver, there appears an asymmetry between “slowly aging” and “fast aging” observers which can be used to have private information transmission.

La primera parte se titula: “Fenomenología de la fenomenología”, cuestión presente desde los orígenes mismos de la fenomenología y preocupación constante de su fundador. En esta parte se abordan tres estudios muy diversos, cuyo eje es el interés por contribuir, sin pretensión de sistematicidad, a una meta-fenomenología. En el primer estudio, el autor se aproxima a una de las preguntas más vitales de la fenomenología, esto es, si existe o no un método fenomenológico. Luego de aclarar las dificultades históricas, epistemológicas (...) y metodológicas (estas últimas llamadas por el autor “procedimentales”) para atreverse a responder a esta pregunta, Vargas Guillén llega a la tesis de su estudio: “la fenomenología, que esencialmente es método, tiene principios, pero no procedimientos” (p. 14).

El presente trabajo, pretende mostrar las críticas básicas de Levinas al concepto de conciencia representacional (en general), o intencional (en particular). No estará ligado netamente al establecimiento de la ética, por tanto, se trabajará con las obras Totalidad e Infinito, De otro modo que ser o más allá de la esencia, De Dios que viene a la idea. Hay que señalar que para Levinas la crítica a la conciencia intencional tiene como fin el establecimiento de la ética como filosofía primera (...) y a este fin se supedita; sin embargo, consideramos que tal crítica no tiene que estar ligada única y exclusivamente a los propósitos levinasianos; podría iluminar otros contextos en los que la propuesta de la conciencia no-intencional contribuiría a renovar los contenidos y las prácticas; pensamos, en primera instancia, en las ciencias humanas, específicamente en sus procesos de investigación.

Se realiza en este artículo un viraje desde el Lacan de sus comienzos psiquiátricos, en 1927, hasta el Lacan de función y campo del lenguaje, donde se considera que comienza su enseñanza en 1953. Es uno de los períodos de Lacan importantes pero quizás menos conocido. Primeramente hablamos de sus andanzas en la psiquiatría, donde tendrá como principal maestro a Gaëtan de Clérembault a quien reconocerá como el único maestro, aunque presentará también la influencia de Jaspers y,poco todavía, de Freud. (...) A partir de 1936, con su escrito «Más allá del principio de realidad» comienza el período imaginario de Lacan donde va a incorporar la fenomenología y el psicoanálisis freudiano cada vez con más solidez e importancia. Finalmente, Lacan comienza no solo a incorporar a Freud, sino la concepción sobre el lenguaje de Heidegger, aunque todavía no como siginificante. Será en 1953, con «Función y campo de la palabra» donde comienza su gran entrada en lo simbólico, abandonando su fase imaginaria, dando entrada a su noción de significante y rompiendo finalmente con la fenomenología y con Jaspers, e integrando completamente a Freud, con el llamado retorno al fundador del psicoanálisis.

Para esto, se comienza presentando la contraposición que establece Levinas entre verdad del desvelamiento y verdad del testimonio, destacando sus diferencias más radicales. Posteriormente, teniendo la subjetividad como hilo conductor, se reconstruye el camino que relacionaría ambos tipos de verdad, mostrando cómo la tesis de la inevitabilidad de lo dicho adquiere relevancia en las discusiones epistemológicas. (...) Finalmente, se concluye sugiriendo algunos aportes de esta reflexión para las consideraciones acerca de una racionalidad renovada.: This paper discusses the Levinasian thesis of the inevitability of the Said, having as its background certain epistemological issues arising from that thesis. I begin by showing the contraposition between truth of disclosure and truth of testimony, as Levinas defines them, and point out the most radical differences between the two. I then reconstruct, with subjectivity as the connecting thread, a way of relating both kinds of truth, showing how the thesis on the inevitability of the Said is relevant to epistemological discussions. I conclude by suggesting some considerations with regard to a renewed rationality. (shrink)

The purpose of the present paper is to demonstrate a series of connections in terms of concepts and subjects between Ockham and Kant’s philosophical models that may provide a comprehensive framework for their respective insights on Law. Our main thesis postulates the existence of a continuum of certain fundamental assumptions derived from Nominalist theology and enlightened rationality that contribute to the essential unity of so-called “modern thought” and how such continuity is projected in the legal domain. In this sense, we (...) suggest the need to reflect upon the tacit Nominalism underlying Kantian criticism, which, although devoid of all theological premises, reconstructs metaphysics while preserving its basic scheme. In order to do so, our starting point is a very brief reference to the similarities between their respective theories of knowledge. We go on to analyze the structure behind moral actions according to Ockham and Kant’s doctrines. Finally, we point to certain founding principles and elements common to both doctrines in the field of legal-political thought. (shrink)

IntroductionThe assessments of the motor symptoms in Parkinson’s disease are usually limited to clinical rating scales, and it depends on the clinician’s experience. This study aims to propose a machine learning technique algorithm using the variables from upper and lower limbs, to classify people with PD from healthy people, using data from a portable low-cost device. And can be used to support the diagnosis and follow-up of patients in developing countries and remote areas.MethodsWe used Kinect®eMotion system to capture the spatiotemporal (...) gait data from 30 patients with PD and 30 healthy age-matched controls in three walking trials. First, a correlation matrix was made using the variables of upper and lower limbs. After this, we applied a backward feature selection model using R and Python to determine the most relevant variables. Three further analyses were done using variables selected from backward feature selection model, movement disorders specialist, and all the variables from the dataset. We ran seven machine learning models for each model. Dataset was divided 80% for algorithm training and 20% for evaluation. Finally, a causal inference model using the DoWhy library was performed on Dataset B due to its accuracy and simplicity.ResultsThe Random Forest model is the most accurate for all three variable Datasets followed by the support vector machine. The CIM shows a relation between leg variables and the arms swing asymmetry and a proportional relationship between ASA and the diagnosis of PD with a robust estimator.ConclusionsMachine learning techniques based on objective measures using portable low-cost devices are useful and accurate to classify patients with Parkinson’s disease. This method can be used to evaluate patients remotely and help clinicians make decisions regarding follow-up and treatment. (shrink)

Carlos Vaz Ferreira argues that the problem of freedom is conceptually distinct from the problem of causal determinism. The problem of freedom is ultimately a problem regarding the ontologically independent agency of a being, and the problem of determinism is a problem regarding explanations of events or acts in terms of the totality of their antecedent causal conditions. As Vaz Ferreira sees it, failing to keep these problems apart gives rise to merely apparent but unreal puzzles pertaining to the (...) nature of freedom and its relation to determinism. In this article, I present my interpretation of Vaz Ferreira’s distinctive ideas regarding the nature of freedom and its relation to casual determinism. (shrink)

Cacao cultivation is one of the most important livelihoods for rural households in Colombia, where it is promoted as a substitute for the illegal cultivation of coca. To strengthen Colombian cacao farming, it is important to understand the livelihood strategies associated with cacao cultivation and the impact of these different strategies on the well-being of Colombian rural households. We analyzed the impact of cacao cultivation on the livelihood strategies and well-being of rural households in western Colombia. Research with 92 rural (...) cacao-growing households produced a typology of household livelihood strategies derived from their approach to cacao production. Indicators of each household capital and level of well-being were identified for each type of households. Correlations between the capitals and the capitals of greater importance in shaping the well-being of rural households were analyzed. Three types of rural households were identified: Cacao Farmers, Diversified Farmers with Cacao, and New Cacao Farmers. Cacao farmers have the highest capitals endowments and level of well-being, followed by Diversified Farmers with Cacao, and New Cacao Farmers. The conditions of cacao cultivation in rural households result in differentiated access to resources from capitals; households with better development of the crop have consolidated greater well-being where human capital has been its major driving factor. Success of the cacao crop and its relationship with well-being of rural households depends on the convergence of different capital resources. Thus, institutional efforts to strengthen the cacao sector in Colombia must go beyond investment to establish new hectares and consider aspects such as: Strengthening the skills and knowledge of producers to improve crop management practices, Promoting the participation of household members in associations, Stimulating sensitivity to the rooting and sustainable management of the crop, and Promoting processes of technification and adaptation of the infrastructure of fermenters and dryers, which will make it possible to guarantee an adequate quality of the cacao bean.
