El ejercicio utópico de la voluntad política que caracteriza el XIX latinoamericano se desgrana en las categorías de unidad continental, unidad cultural, unidad en el concepto de Patria, etc.; clausurando un apretado siglo de extrema densidad social y política, un siglo de utopía en el discurso. Una Ilustración insuficiente, el coste del hibridismo, las comunidades imaginadas, las dependencias encadenadas, las resistencias, los logros y los fracasos, traducen el sacrificio, la traición y la inconclusión de la tarea emancipatoria. Si podemos contemplar (...) hoy día el descubrimiento de América como el comienzo de una empresa civilizatoria, y admirar sus obras más allá del trabajo infatigable de una destrucción que no ha cesado, es sólo en virtud de esta tradición de crítica y resistencia , a lo largo de un proceso social, artístico y literario ininterrumpido hasta el día de hoy.

En este artículo se busca indagar, por un lado, las aporías que Gadamer detecta en la propuesta epistemológica de Dilthey y, por el otro lado, las aporías que el propio Dilthey encuentra en el obrar de las ciencias del espíritu. El objetivo de este artículo será mostrar las limitaciones de la crítica gadameriana y reconocer que la obra de Dilthey excede el análisis exclusivamente objetivista. Esto permitirá demostrar que la filosofía de Dilthey es una indagación del mundo humano entendido como (...) mundo activo. En otros términos, sus estudios son más que una investigación epistemológica. Se buscará sostener que la fundamentación de las ciencias del espíritu desarrollada por él se sostiene gracias a su investigación sobre la dinámica de la vida humana, del mundo común e histórico donde actúa el hombre. This paper seeks to investigate, on one hand, the aporiae that Gadamer detects in Dilthey's epistemological theory, and, on the other hand, the aporiae that Dilthey himself finds in the work of the human sciences. The goal of this paper is to show the limitations of Gadamer's critique and to recognize that Dilthey's work exceeds the objectivist analysis. This will allow proving that Dilthey's philosophy is an inquiry into the human world understood as an active world. In other words, his studies are more than an epistemological investigation. I will seek to claim that the basis of the human sciences developed by him is the result of his research on the dynamics of human life, on the common and historical world where man acts. (shrink)

Este artículo se enmarca en una línea de investigación que pretende analizar el humor como estrategia creativa en el ensayo audiovisual español. Para ilustrar el objetivo propuesto, se han revisado tres largometrajes que, a pesar de su diversidad, encajan, de una u otra forma y con diversos objetivos, en esta manera de enunciación cinematográfica: La casa Emak Bakia (Oskar Alegria, 2012), Mapa (Elías León Siminiani, 2012) y Muchos hijos, un mono y un castillo (Gustavo Salmerón, 2017). Los tres comparten algunas (...) características del ensayo audiovisual (la reflexividad, la escritura del yo y una preocupación estética que llega al cuestionamiento de las propias formas de expresión) y recurren al humor como un recurso para construir sus relatos. Por ello, se han revisado algunas de las características del ensayo audiovisual, se ha analizado el humor como elemento narrativo que se consigue a través de diversas instancias enunciativas y se ha pasado revista a dos recursos al servicio del humor.

As far as we are aware, this study presents the first comparative analysis of the stock picking and market timing abilities of managers of conventional and socially responsible (SR) pension funds, and of their use of superior information. For the United Kingdom, the results obtained show a slight stock picking ability on the part of SR pension fund managers (although it disappears if multifactorial models are considered), and a negative market timing ability on the part of both SR and conventional (...) pension fund managers (these results hold for multifactorial models controlled by home bias). In relation to the management styles, both conventional and SR pension funds usually invest in small cap and growth values, although it is the SR pension funds that are the most exposed to these styles. We also observed that, while conventional pension fund managers make certain use of superior information to follow stock picking strategies, managers of SR pension funds use superior information to follow market timing strategies.

O tradicional problema do conhecimento do singular mantém-se hoje em dia: o impasse assinalado por Aristóteles prevalece na maioria das ciências actuais que lidam precisamente com casos particulares, contingentes, imprevisíveis, que escapam ao enquadramento nos modelos categoriais. Este Colóquio sobre O Estatuto do Singular constituiu um desafio para todos aqueles que em diversas áreas filosóficas e científicas se enfrentam com a necessidade de repensar modelos e estratégias aplicáveis ao caso prático, à decisão, à acção, à inovação, à invenção; noções como (...) o incerto, o provável, o casual, o frequente, o diferente, o imprevisível - exigem um novo modo de pensar e uma revisão das formas típicas da racionalidade. O tópico convocou, além da filosofia, uma ampla gama de domínios: desde as ciências e artes médicas, a biologia, até ao direito e às ciências humanas e sociais, passando também pela literatura e a arte. O que se pretendeu foi apresentar uma sinopse de diferentes olhares e perspectivas sobre um ponto de mira comum: «o estatuto do singular» foi o leit motiv para abrir um horizonte de pensamento e de diálogo profícuo e abrangente.

Aunque el denominado problema de marco generó múltiples debates a finales del siglo pasado, aún es un problema fundamental para el avance en las Ciencias Cognitivas, en general, y para la Inteligencia Artificial, en particular. En este trabajo, y restringiéndonos al aspecto lógico del problema, postulamos que la discusión actual y subyacente a este aspecto gira en torno a cómo determinar lo que no cambia en términos de acciones y propiedades dentro de un sistema lógico formal. Es sobre este aspecto, (...) y en función de sus dificultades (i) definicional y (ii) resolutiva, que en este trabajo argumentaremos que el denominado “criterio temporal” no solamente puede estimarse como uno los principales requerimientos teóricos para (i) resolverlo sino también para (ii) explicitar más claramente su dificultad principal, a saber, “lo que es relevante” frente al cambio en el tiempo. De esta manera, sostenemos que el razonamiento lógico-temporal resulta necesario para construir cualquier solución íntegramente satisfactoria del aspecto lógico del problema de marco entendido como el modo en que, inmediatamente, determinamos relevancia frente al cambio.

The rating of perceived exertion can be used to monitor the exercise intensity during laboratory and specific tests, training sessions, and to estimate the internal training load of the athletes. The aim of the present study was to develop and validate a specific pictorial perceived exertion scale for soccer players called GOAL Scale. The pictorial GOAL Scale was validated for twenty under-17 soccer players. In the validation phase, the athletes were evaluated in a progressive protocol involving stimuluses of 3 min (...) with 1 min for the rest into the stages until the voluntary exhaustion in Maximal Cardiopulmonary Effort Test, and in the Yo Yo Intermittent Recovery Test – Level 1. The RPE identified by the GOL Scale, by the Borg Scale 6 – 20 and by the Cavasini Scale, as well as the heart rate, perceptual of the heart rate and the blood lactate concentration were immediately evaluated after each stage of both tests. Spearman’s correlation coefficient was used. Construct scale validity was examined by regressing GOAL Scale against Borg Scale 6 – 20 and Cavasini Scale and concurrent scale validity was investigated by regressing GOAL Scale against HR, beats/min and blood lactate concentration during two progressive tests. There was a significant correlation values of the GOAL Scale with Borg Scale, Cavasini Scale, %HRmax, HR and lactate during tests. The results evidenced concurrent and construct validity of the GOAL Scale across a wide range of exercise intensity. The absence of verbal anchors makes the use of this instrument to soccer, futsal and beach soccer athletes of different languages and different literacy levels possible. (shrink)

Soccer players inescapably live under stress during the sportive career, and many real-life aspects of soccer situations operate in the ongoing performance. This study’s main objective was to elaborate the List of Stressors in Professional Indoor and Field Soccer, a self-report instrument designed to measure the impact of 77 soccer situations upon the sport performance. Participants were 138 indoor and field soccer players from the Brazilian Premier League. Each situation was evaluated on a 7-point scale, ranging from the most negative (...) to the most positive. Data were analyzed according to the players’ perception of the items: distress or eustress and its intensity, and after that, situations perceived as plus −1 and +1 were compared by time in which they were experienced and distributed among five categories established by the literature: Expectations about the Performance, Personal Factors, Competition Aspects, Training Demands, and Relationship with Significant People. Narratives of athletes’ experiences were also used to discuss the results. An Exploratory Structural Equation Modeling using Bi-factorial was employed to assess the factor structure. For the total participants, 49 situations were perceived as distress and 28 as eustress. Using the criteria established a priori, the distribution was among the five categories in the remaining 32 situations. Differences in perception between less and more experienced players were found in 11 situations. The results revealed that Brazilian professional soccer players experience various stressful situations. These events are important representations of environmental demands and could predict the performance as they are perceived as eustress or distress. Some of these stressful situations are inherent in sport and others adjacent to the sports system or environment. Coach pressure to win and conflicts with teammates are examples of stressors in-sport, family problems and disputes with press or fans are examples of stressors external to the team, also called peripheral opponents, and showed the relative social influence of significant others in soccer performance. We can conclude that the knowledge of the direction of a given stress situation has important practical implications in preparing athletes and helping them face the performance stressors that are part of soccer daily life.

In this article, we present a work developed with palliative patients with the aim of, through art, enabling them to find answers that would help them overcome situations that kept them involved in thoughts, fears, and anxiety that consumed their energy, joy, and will to live. For this purpose, we used a qualitative methodology —research-action— and the attained results revealed how arts can be useful to these patients by providing them, through the work they have developed, with an improvement in (...) self-esteem, disposition, and well-being in disease avoidance and the expression and communication of emotions.

Los actos violentos que se narran en La cinta blanca (Michael Haneke, 2009) nos llevan a plantearnos ciertas cuestiones sobre lo que Hannah Arendt dio en llamar “banalidad del mal” y cómo dicho concepto se refleja en el filme. Retomando algunas de las cuestiones planteadas por la autora en sus obras Los orígenes del totalitarismo (1951), La condición humana (1958) y Eichmann en Jerusalén. Un estudio sobre la banalidad del mal (1963) trataremos de dar respuesta a las siguientes preguntas: ¿son (...) los niños/as incapaces de percibir la maldad de sus actos?, ¿son conscientes moralmente?, ¿la violencia se utiliza como una forma de revelarse frente a la autoridad o como un modo de poner en juego los valores que ésta les ha enseñado? Es decir, ¿podemos hablar de la banalidad del mal para describir los actos de los/as niños/as? La respuesta a esta pregunta parece ser afirmativa, pero cabe establecer una distinción importante entre los diferentes actos que se describen en el filme, para esto acudiremos también a las ideas de autores como Peter Sloterdijk y Jean Paul Sartre.

Batteries are a fundamental storage component due to its various applications in mobility, renewable energies and consumer electronics among others. Regardless of the battery typology, one key variable from a user’s perspective is the remaining energy in the battery. It is usually presented as the percentage of remaining energy compared to the total energy that can be stored and is labeled State Of Charge (SOC). This work addresses the development of a hybrid model based on a Lithium Iron Phosphate (LiFePO4) (...) power cell, due to its broad implementation. The proposed model calculates the SOC, by means of voltage and electric current as inputs and the latter as the output. Therefore, four models based on k-Means, Agglomerative Clustering, Gaussian Mixture and Spectral Clustering techniques have been tested in order to obtain an optimal solution. (shrink)

The present commentary addresses the main results obtained in the Butler and Klein [Butler, B. C., & Klein, R. . Inattentional blindness for ignored words: Comparison of explicit and implicit memory tasks. Consciousness and Cognition, 18, 811–819.] study and discusses them in relation to the Perceptual Load Theory of Lavie [Lavie, N. . Perceptual load as a necessary condition for selective attention. Journal of Experimental Psychology: Human Perception and Performance, 21, 451–68.]. The authors claim that the use of implicit indexes (...) of conceptual distractor processing in high-load situations would be an important addition to the load literature, which would benefit the research field regardless of their positive or negative findings.

Much of the methodological discussion around experiments in economics and other social sciences is framed in terms of the notions of internal and external validity. The standard view is that internal validity and external validity stand in a relationship best described as a _trade-off_. However, it is also commonly held that internal validity is a _prerequisite_ to external validity. This article addresses the problem of the compatibility of these two ideas and analyzes critically the standard arguments about the conditions under (...) which a trade-off between internal and external validity arises. Our argument stands against common associations of internal validity and external validity with the distinction between field and laboratory experiments and assesses critically the arguments that link the artificiality of experimental settings done in the laboratory with the purported trade-off between internal and external validity. We conclude that the idea of a trade-off or tension between internal and external validity seems, upon analysis, far less cogent than its intuitive attractiveness may lead us to think at first sight.

This paper aims to enhance security in IoT device networks through a visual tool that utilizes three projection techniques, including Beta Hebbian Learning (BHL), t-distributed Stochastic Neighbor Embedding (t-SNE) and ISOMAP, in order to facilitate the identification of network attacks by human experts. This work research begins with the creation of a testing environment with IoT devices and web clients, simulating attacks over Message Queuing Telemetry Transport (MQTT) for recording all relevant traffic information. The unsupervised algorithms chosen provide a set (...) of projections that enable human experts to visually identify most attacks in real-time, making it a powerful tool that can be implemented in IoT environments easily.

The authors present some remarks on Al- Farabi's reception and understanding of Platonic Dialogues, especially according to "The Philosophy of Plato". In this treatise, Al- Farabi intends to show how politics were meant to be the leitmotiv of Plato's writings. He also discusses the argumentative and cognitive relations that exist between Political Science, Philosophy and Religion. As the statesman is engaged in pedagogical functions, he is urged to have some discursive abilities —besides the speculative knowledge of the first principles— for (...) him to incite the multitude to act.

Like theories, reconstructions of episodes in the history of science can possess, or lack, certain virtues such that, when we face two or more different reconstructions of the same episode, we assume that we should choose the most “virtuous one”. However, we will argue that, with dissimilar reconstructions of the same episode, it is not always necessary to separate the “good ones” from the “wrong ones”, and that, as a matter of fact, each reconstruction could provide different but perhaps equally (...) relevant data about the episode, about science in general, and about particular philosophical theses. In order to help us to identify these benefits, we will present a criterion that guides the search for historiographical reinforcement of philosophical theses and we will use it to evaluate three different reconstructions of the same scientific episode.

Background:The acquisition of experience is a major concern for nurses in intensive care units. Although the emotional component of the clinical practice of these nurses has been widely studied, greater examination is required to determine how this component influences their learning and practical experience.Objective:To discover the relationships between emotion, memory and learning and the impacts on nursing clinical practice.Research design:This is a qualitative phenomenological study. The data were collected from open, in-depth interviews. A total of 22 intensive care unit nurses (...) participated in this research between January 2012 and December 2014.Ethical considerations:The School of Nursing Ethics Committee approved the study, which complied with ethical principles and required informed consent.Findings:We found a clear relationship between emotion, memory and the acquisition of experience. This relationship grouped three dimensions: (1) satisfaction, to relieve the patient’s pain or discomfort, give confidence and a sense of security to the patient, enable the presence of family members into the intensive care unit and provide family members with a realistic view of the patient’s situation; (2) error experience, which nurses feel when a patient dies, when they fail to accompany a patient in his or her decision to abandon the struggle to live or when they fail to lend support to the patient’s family; and (3) the feel bad–feel good paradox, which occurs when a mistake in the patient’s care or handling of his or her family is repaired.Conclusion:Emotion is a capacity that impacts on nurses’ experience and influences improvements in clinical practice. Recalling stories of satisfaction helps to reinforce good practice, while recalling stories of errors helps to identify difficulties in the profession and recognise new forms of action. The articulation of emotional competencies may support the development of nursing ethics in the intensive care unit to protect and defend their patients and improve their relationships with families in order to maximise the potential for patient care.

In this study, we analyze the financial performance and the managerial abilities of religious mutual fund managers, implementing a comparative analysis with conventional mutual funds. We use a broad sample, free of survivorship bias, of religious equity mutual funds from the US market, for the period from January 1994 to September 2010. We build a matched-pair conventional sample in order to compare the results obtained for both kinds of mutual fund managers. We analyze stock-picking and market timing abilities, topics widely (...) neglected for the specific case of religious mutual fund managers. We also study style timing abilities. As far as we are aware, this aspect has not been studied previously for religious mutual fund managers. Our results indicate that religious mutual fund managers underperform both the market and their conventional counterparts. This result is driven by negative stock-picking ability which could be generated by excluding “Sin” stocks from their portfolios. Moreover, they are not able to time the market or any of the following styles: size, book-to-market, and momentum. (shrink)

Durante la primera década del siglo XX el 90% de los migrantes provenía de Europa y se dirigía a cinco países: EEUU, Argentina, Canadá, Brasil y Australia. Hoy esa misma proporción de migrantes proviene de tres continentes: Asia, África y Latinoamérica y se dirige a cuatro grandes regiones: Europa, Norteamérica, Asia Pacífico y El Golfo Pérsico. Las migraciones se han mundializado no tanto por la magnitud de los flujos, que sigue estando por debajo del 5% de la población mundial, sino (...) por el .. (shrink)

As a result of recent corporate scandals, several rules have focused on the role played by Boards of Directors on the planning and monitoring of corporate codes of ethics. In theory, outside directors are in a better position than insiders to protect and further the interests of all stakeholders because of their experience and their sense of moral and legal obligations. Female directors also tend to be more sensitive to ethics according to several past studies which explain this affirmation by (...) early gender socialization, the fact that women are thought to place a greater emphasis on harmonious relations and the fact that men and women use different ethical frameworks in their judgments. The goal of this paper is to determine the influence of these characteristics of the Board in terms of promoting and hindering the creation of a code of ethics. Our findings show that a greater number of female directors does not necessarily lead to more ethical companies. Moreover, within Europe as a continent, board ownership leads to an entrenchment of upper-level management, generating a divergence between the ethical interests of owners and managers. In light of this situation, the presence of independent directors is necessary to reduce such conflicts. (shrink)
