The use of wireless sensor networks and the Internet of things to detect forest fire outbreaks may help to reduce the response time and avoid natural disasters. This work proposes the deployment of WSN to enhance the real-time monitoring of dynamic variables such as polluting gases, temperature or the presence of fire flames by infrared. In addition, the activation of forest fire alerts if environmental status may involve evidence of a recent fire outbreak. A fuzzy-based controller is implemented to manage (...) the uncertainty related to estimating forest fire occurrence and dynamic update of fuzzy sets is developed to distinguish usual and unusual environmental conditions of every monitored forest area. Merkle trees, AES and hash functions are considered to protect the integrity of environmental data. (shrink)

Huge losses and serious threats to ecosystems are common consequences of forest fires. This work describes a forest fire controller based on fuzzy logic and decision-making methods aiming at enhancing forest fire prevention, detection, and fighting systems. In the proposal, the environmental monitoring of several dynamic risk factors is performed with wireless sensor networks and analysed with the proposed fuzzy-based controller. With respect to this, meteorological variables, polluting gases and the oxygen level are measured in real time to estimate the (...) existence of forest fire risks in the short-term and to detect the recent occurrence of fire outbreaks over different forest areas. Besides, the Analytic Hierarchy Process method is used to determine the level of fire spread, and, when necessary, environmental alerts are sent by a Web service and received by a mobile application. For this purpose, integrity, confidentiality, and authenticity of environmental information and alerts are protected with implementations of Lamport’s authentication scheme, Diffie-Lamport signature, and AES-CBC block cipher.

This paper presents two formation tracking control strategies for a combined set of single and double integrator agents with an arbitrary undirected communication topology. The first approach is based on the design of distance-based potential functions with interagent collision avoidance using local information about the distance and orientation between agents and the desired trajectory. The second approach adds signed area constraints to the desired formation specification and a control strategy that uses distance as well as area terms is designed to (...) achieve tracking convergence. Numerical simulations show the performance from both control laws. (shrink)

Resumen El propósito de este trabajo es profundizar en el concepto de actividad de imagen y defender su utilidad como categoría de estudio para comprender diferentes tipos de comportamiento que afectan a la imagen social de los hablantes en la interacción comunicativa: cortesía, descortesía y actividad de autoimagen. Teniendo como base estudios sociopragmáticos del español desde una perspectiva cultural y estudios teóricos en inglés de la última década, se tratará el concepto de actividad de imagen, el cual se caracteriza de (...) acuerdo con dos conceptos claves: el del efecto social que un comportamiento comunicativo tiene sobre las imágenes de los hablantes y el del continuo social, la conexión que se establece entre sus imágenes en la interacción. De esta forma, se propone tratar la actividad de imagen desde dos perspectivas relacionadas: la de la dirección seguida por el efecto social hacia los interactuantes y la de las características de este efecto, siendo su interrelación el factor que permite identificar y caracterizar el tipo de actividad de imagen.

In this work we will analyze the main features of Sartre’s ontological-phenomenological theory in Being and Nothingness, linking them with some key historical precedents. By clarifying the connections of this theory with the former philosophical tradition on the subject of Being, its role in existence, reality’s nature and its relation to the phenomenon, the actual contribution of Sartre in this matter is demonstrated.

Por un lado, el libro aborda la problemática educativa que enfrentan estudiantes mexicanos indocumentados en las universidades de los Estados Unidos. Por el otro lado, se aborda la atención específica (escolar, académica y administrativa) que la Universidad de Guadalajara (México), ofrece a los estudiantes migrantes retornados de los Estados Unidos.

El objetivo de esta investigación se centra en observar los eventos organizados por las empresas más responsables según el ranking MERCO, teniendo en cuenta si cumplen con las características de sostenibilidad definidas por la ISO 20121 sobre sistemas de gestión de sostenibilidad de eventos, que son: inclusividad, integridad, responsabilidad y transparencia. Para ello se analizarán todos los eventos, prestando especial atención a aquellos específicamente considerados como sostenibles. Los resultados muestran que menos de la mitad siguen criterios de sostenibilidad en su (...) realización. Llama la atención que la Norma ISO 20121 es de escasa aplicación en las organizaciones más responsables de España. (shrink)

Do we empathize with the others because first we have recognized them as somehow equals, or do we recognize them as equals because first we have empathized with them? This article explores the relation between affective empathy, the moral recognition of the others, and personal identity. I defend that, to recognize others as valuable and act in line with this, one must be able to feel affective empathy for their situation, and, to do so, one has to 1) be curious (...) about them to surpass indifference, and 2) feel that your identity is not threatened by recognizing the others. Otherwise, rationalizations and justifications of antisocial behaviors would arise. Thus, I focus on how the construction of the self plays a key role in prosocial behaviors and the activation of affective empathy, which has been overlooked by moral philosophy in the debate on empathy. In order to do so, firstly, I explore cases where moral recognition is broken, secondly, I explore the dichotomic debate on the role of empathy for moral recognition and moral agency, and, thirdly, I try to enrich the debate by shifting the focus to the prerequisites to feel empathy, such as curiosity, a well-integrated self and healthy narcissism, addressing so how the construction of the self plays a key role in the possibility of empathizing with others and, therefore, in epistemic virtues and moral agency. As a result, I advocate the importance of psychological education for moral agency. (shrink)

Formelle Bildung es el concepto de Hegel para determinar la función histórica del arte en el mundo moderno. Esta función contrasta con la inhaltliche o la substantielle Bildung que proporcionó el arte en el mundo oriental y el mundo clásico griego, y en general, con la función decisiva que desempeña el arte en el ethos de culturas donde el arte es inseparable de la religión, donde según Hegel, el arte opera según su determinación suprema. Pero si bien el arte en (...) la cultura moderna ya no puede ser Kunstreligion, religión de arte, ello no significa que haya perdido su función como factor de cultura, sino que sigue siendo imprescindible en ella, aunque ya no para que la comunidad se identifique con los contenidos que el arte le representa, sino para que los individuos se confronten con ellos de un modo crítico-reflexivo. En el mundo moderno el arte ya no es arte de una comunidad, sino de y para una sociedad, de modo que el Estado y la institucionalidad están de por medio. El arte ya es autónomo y no determina doctrinaria o ideológicamente el ethos, pero por la forma de proporcionarle sus intuiciones y sus representaciones a la reflexión, fomenta el ejercicio libre del juicio de los individuos. Según Hegel, el carácter "formal" de la cultura que proporciona el arte en el mundo moderno hace que el arte se convierta en asunto fundamental de política cultural, donde arte y público pasan al primer plano.

The numerous biographies on Ignatius of Loyola’s that emerged in recent years have rarely addressed the post mortem treatment received by the body of the Holy Jesuit. Even more, those that actually talked about this chapter of the Saint’s life did not take into account the descriptive and interpretive richness that provides the History of Medicine. Therefore, this paper aims to reconstruct the postmortem treatment received by the body of Ignatius of Loyola’s. In addition, we aim to suggest some ideas (...) about the health professionals who performed the autopsy and subsequent embalming of the corpse, the “signs of holiness” found in the body and the places where it was preserved.

Este artículo nos adentra en el estudio del problema del “jansenismo español” durante el siglo de Ilustración. En la primera parte se presenta el origen del jansenismo teológico, moral y disciplinar. Se indican sus representantes y sus obras. Más tarde se convierte en jansenismo político, también llamado jansenismo histórico. La influencia del pensamiento de los jansenistas franceses, holandeses e italianos sobre los jansenistas españoles es evidente y fehaciente. La historiografía sobre el particular es abundante. Se presentan las características más importantes (...) del jansenismo español, en relación con el despotismo ilustrado, el regalismo y el reformismo, además de un gran interés por la Biblia, el Derecho y la Historia.

Kalinowski conceives metaphysics as a set of propositions which can be axiomatized. This paper exposes the typical rules of an axiomatic system comparing them with the metaphysical system developed by Kalinowski. These rules are linguistic rules, but also admission-rules and transformation-rules. They always refer to the metaphysical propositions (wich are first or second propositions, as it is usual in logical systems). This paper tries to evaluate Kalinowski's attempt.

In this paper I argue that there is not epistemological and methodological consensus in disciplines that collaborate on social research visual analysis. I propose that in this field we can found an epistemological choice under a constructivist perspective that considers both intersubjetivity a..

RESUMEN Con frecuencia el amor y la racionalidad se ven como capacidades que fácilmente entran en conflicto, cuando no se consideran por principio opuestas. En este artículo desarrollo algunos puntos esbozados por Harry Frankfurt con el fin de proponer que la relación entre amor y racionalidad no es de simple oposición. Tras ofrecer una caracterización del amor como disposición híbrida de seguimiento múltiple, defenderé que el amor es racional en el siguiente sentido: el amor no es justificable, pero a pesar (...) de ello es una fuente de razones básicas y a veces irresistibles que en buena medida informan el campo de nuestra racionalidad. Esto no significa que el amor sea una base irracional o arracional, o que sea completamente blindado a la razón, sino que en circunstancias específicas tiene sentido someter el amor a escrutinio racional. ABSTRACT Love and rationality are often considered as capacities which easily come into conflict, or are even opposed to one another. In the paper I elaborate some points suggested by Harry Frankfurt in order to propose that the relation between love and rationality is not one of opposition. After offering a characterization of love as a hybrid multi-track disposition, I will argue that love is rational in the following sense: although love is not justifiable, it is nevertheless a source of basic and sometimes irresistible reasons which to a large extent shape the field of our rationality. This does not mean that love is an irrational or arrational foundation, or that it is impervious to reason; it only means that in certain circumstances it makes sense to subject love to rational scrutiny.

Taking the work of Gianni Vattimo and Santiago Zabala, Hermeneutic Communism, as a point of departure, this essay explores the concept of pensiero debole (weak thought) and its application to progressive contemporary Latin American governments, which the authors describe as “communist in spirit.” The essay embraces pensiero debole as a method to disagree with Vattimo and Zabala’s assessment and to contrast the policies of state capitalism carried out by those governments to the praxis of anti-systemic social movements engaged in a (...) reformulation of territorial autonomy consonant with what John Holloway calls Change the World Without Taking Power.

Probablemente nunca la teología sacramental ha tenido un florecimiento tan grande como en este último siglo pero, paradójicamente, esto ha ido unido a un extrañamiento cada vez mayor del hombre respecto a los sacramentos, derivado de cuestionamientos de diversa índole. Este artículo, presentado en las XXX Conversaciones de Salamanca, pretende pasar de los cuestionamientos a las cuestiones actuales de fondo que están en juego en la teología sacramental, para poder ofrecer una propuesta de ense- ñanza renovada de los sacr.

In this article we focus on the emergence of biological individuality by association, trying to formulate some theoretical conditions to think about the process of collective individualization. The starting point of our analysis is the notion of “major evolutionary transition.” A major evolutionary transition is the result of the integration of a multiplicity of initially independent biological entities that, by managing to organize their interactions, become a collective of components having an identity oriented towards a common goal. When biological organisms (...) are concerned, a major transition corresponds to a phenomenon of fusion between them. We shall argue that the emergence of a new biological level of individuality implies the establishment of constitutive relationships between individuals that change their status as autonomous entities. As a result, the emergence of a new type of entity in the living world implies that individuals enter into relationships that intrinsically transform them, a transformation sufficient for a “whole” to become a “part” that forms another “whole”, that is, a new level of organismality.

El siguiente trabajo pretende mostrar algunas conexiones ontológicas y epistemológicas entre los supuestos que subyacen en la conservación de la energía en física y la teoría del valor en economía clásica. Para ello, en primer lugar, haré una reconstrucción de ciertos supuestos metafísicos y hallazgos empíricos que guían la configuración de la conservación de la energía, desde la época de Descartes hasta su elaboración formal por parte de Helmholtz, como principio termodinámico. A continuación, describiré cómo encontramos supuestos equivalentes, con otra (...) elaboración, que guían las preocupaciones sobre el valor en los economistas clásicos en Smith, Ricardo y particularmente en Marx, y sus respectivas conexiones con la física. Finalmente conectaré estos paralelismos que se siguen de tales construcciones, que a su vez provienen de supuestos comunes e inmersos en la cultura y que interactúan en este caso en física y economía. Con ello argumentaré en favor de una perspectiva no autónoma de la ciencia, determinada por tales factores culturales de su tiempo. (shrink)
