The Air Quality Index (AQI) shows the state of air pollution in a unique and more understandable way. This work aims to forecast the AQI in Algeciras (Spain) 8 hours in advance. The AQI is calculated indirectly through the predicted concentrations of five pollutants (O3, NO2, CO, SO2 and PM10) to achieve this goal. Artificial neural networks (ANNs), sequence-to-sequence long short-term memory networks (LSTMs) and a newly proposed method combing a rolling window with the latter (LSTMNA) are employed as the (...) forecasting techniques. Besides, two input approaches are evaluated: using only the data from the own time series of the pollutant in the first case or adding exogenous variables in the second one. Several window sizes are employed (24, 28 and 72 hours) with ANNs and LSTMNAs. Additionally, several feature ranking methods are applied in the exogenous approach to select the most relevant lagged variables to feed the models. Results show how the proposed exogenous approach increases the performance of the prediction models. Besides, the newly proposed method LSTMNA provides the best performances in most of the cases evaluated. Hence, it constitutes an exciting alternative to standard LSTMs and ANNs to predict pollutants concentrations and, consequently, the AQI. (shrink)

The objective of this research is to develop accurate forecasting models for chlorophyll-α concentrations at various depths in El Mar Menor, Spain. Chlorophyll-α plays a crucial role in assessing eutrophication in this vulnerable ecosystem. To achieve this objective, various deep learning forecasting techniques, including long short-term memory, bidirectional long short-term memory and gated recurrent uni networks, were utilized. The models were designed to forecast the chlorophyll-α levels with a 2-week prediction horizon. To enhance the models’ accuracy, a sliding window method (...) combined with a blocked cross-validation procedure for time series was also applied to these techniques. Two input strategies were also tested in this approach: using only chlorophyll-α time series and incorporating exogenous variables. The proposed approach significantly improved the accuracy of the predictive models, no matter the forecasting technique employed. Results were remarkable, with |$\overline{\sigma}$| values reaching approximately 0.90 for the 0.5-m depth level and 0.80 for deeper levels. The proposed forecasting models and methodologies have great potential for predicting eutrophication episodes and acting as decision-making tools for environmental agencies. Accurate prediction of eutrophication episodes through these models could allow for proactive measures to be implemented, resulting in improved environmental management and the preservation of the ecosystem.

In the context of solving large distributed constraint optimization problems, belief-propagation and incomplete inference algorithms are candidates of choice. However, in general, when the problem structure is very cyclic, these solution methods suffer from bad performance, due to non-convergence and many exchanged messages. As to improve performances of the MaxSum inference algorithm when solving cyclic constraint optimization problems, we propose here to take inspiration from the belief-propagation-guided decimation used to solve sparse random graphs. We propose the novel DeciMaxSum method, which (...) is parameterized in terms of policies to decide when to trigger decimation, which variables to decimate and which values to assign to decimated variables. Based on an empirical evaluation on a classical constraint optimization benchmarks, some of these combinations of policies, using periodic decimation, cycle detection-based decimation, parallel and non parallel decimation, random or deterministic variable selection and deterministic or random sampling for value selection, outperform state-of-the-art competitors in many settings.

This article studies natural food packaging as enabling artifacts of the traditional material culture of Antioquia in Colombia. For this purpose, we consider artifacts as objective nodes that combine design and use intentions, functions, materials, histories, artifactual lineages, and cooperative relationships that stabilize ritualized practices of a human group. We take the example of natural packaging as artifacts that enablers and stabilizers of traditional cooking and food preparation practices. Natural packaging materials are here assumed to be leaves having some favorable (...) property to contain a food product. After providing a theoretical reflection, we analyze the data collected from fieldwork we conducted in two towns in Antioquia, Colombia (Santa Fe de Antioquia and Amagá), as well as from an interview with an expert in the field. Finally, we show that it is possible to postulate an analysis under a relational ontological description of a traditional practice with conceptual categories of the philosophy of technology.

Este artículo introduce un concepto nuevo con el que poder comprender el Quijote : el socratismo cristiano. Un elemento del ascetismo que impregnaba la España barroca de la Contrarreforma, y del que participaba Cervantes. El Quijote es una guerra entre Cervantes y don Quijote, o dicho de otra forma, entre el último capítulo y los restantes, entre el Barroco y el Renacimiento –y su continuación, la modernidad- expresión literaria de la guerra entre el Imperio español y Europa. Su carácter dialéctico (...) se refleja incluso en el enfrentamiento entre las dos corrientes interpretativas preponderantes. (shrink)

La manifestación de Jesús tiene su punto culminante en el último día de la fiesta de las Tiendas, en el templo de Jerusalén (Jn 7,38-39). Jesús se proclama poseedor y dador del Espíritu. De la comunión con Cristo emerge la potencia del amor divino, el Espíritu, en el creyente. Cristo resucitado, el Espíritu, la libertad, están en relación de mutua implicación, y constituyen un contexto existencial unitario en la persona que los acoge, según san Pablo. Es preciso tomar (...) conciencia del Espíritu presente en nuestra interioridad. Religiosas/os han encarnado la fertilidad del Espíritu y la ilustran para nuestro tiempo. Para entender la vitalidad, la acción del Espíritu que reciben los creyentes debemos mirar a María. (shrink)

La racionalidad de la globalización está basada en la relación instrumental mediobeneficio. La planificación económica para la obtención de mayores ganancias cada vez en los distintos mercados parece exigir una incesante no-intervención del Estado. Sin embargo, la dinámica de la acumulación y reproducción del capital precisa de una neo-planificación de las estrategias económicas con el consentimiento del Estado en negociación con agentes transnacionales a nivel tanto estrictamente nacional y regional como global. Dicha delineación de los parámetros económicos alumbra ciertos efectos (...) en sectores antaño regulados en exclusiva por el Estado-Nación: a saber, el derecho, la sociedad y las relaciones internacionales. De igual forma, la democracia como sistema de gobierno sufre los avatares de la economización creciente de la política, consentida por los poderes públicos. Por tanto, los derechos económicos, sociales y culturales, consagrados en las cartas constitucionales como derechos fundamentales, junto al subsidiario modelo de Estado Social, son puestos en tela de juicio de manera continua por parte de la racionalidad económica, que observa en los mismos un obstáculo a salvar para la maximización de los beneficios.

El presente trabajo muestra un posible e inmediato ejemplo precursor del Patio de los Leones de la Alhambra de Granada. El monasterio de Santa Clara de Tordesillas fue un importante palacio construido por el rey de Castilla Pedro I en la década de los cincuenta del siglo xiv. En su interior existía un patio con pabellones adelantados de su eje principal. Al poco tiempo, Muhammad V, amigo del rey castellano, erigió después de 1362 el Palacio y el Patio de Los (...) Leones de la Alhambra. Mientras que en Tordesillas se dispuso una alberca en su centro, en Granada se optó por la solución del patio de crucero. La fórmula de los pabellones desplegada en el palacio de Pedro I tuvo que tomarse de los lavabos monumentales de los monasterios cistercienses cercanos. Gracias a las buenas relaciones existentes entre los dos monarcas, la solución pudo ser llevada de Tordesillas a Granada por artistas que estuvieran trabajando para los dos reinos. (shrink)

ABSTRACT In this article we analyze the attempt that young Simone Weil made for thinking time and change, and for deciphering the participation that the world and the mind may have in its configuration. To achieve this, we set out to elucidate two concepts that we believe synthesize her approach: the first one is astonishment, understood both in its quality of incessant intuition that reveals the human impotence to understand the present, and in its quality as a mediating instance between (...) ignorance and approximate human science of the phenomenal field. The second concept we analyze is that of directed time, significant of the first Weilian philosophy in that it reveals the subjugation of man to the present, the only tangible time. This determination allows us to understand the meaning of the past as an abolished existence, and the future as a virtual nucleus of possibilities towards which the human being prepares his action and work thanks to his faculty to devise projects. Finally, we try to show the problematic tension that young Weil discerned between the law of the immediacy of the world, and the law of time that imposes intermediate steps to the realization of all human activity.

Resumen La cuestión del tiempo es uno de los principales objetos de estudio que ocuparon a Simone Weil. En efecto, está intensamente presente en su obra desde sus primeros textos hasta sus últimos escritos. La razón es de peso: para esta autora es a través del tiempo que accedemos a la realidad y a toda posibilidad de sentido en sta. Ahora bien, nuestra intención es mostrar que si bien es cierto que la concepción del tiempo de S. Weil, en sus (...) años de madurez, se erige desde una perspectiva espiritualista, mística y religiosa, en su primera época la filósofa se instala en una ontológica fuertemente influenciada por Kant, que la lleva a restringir lo temporal al marco de la experiencia posible, en el sentido que le da el pensador alemán.The question of time is one of the most important subjects in Simone Weil’s philosophy. Indeed, time’s issue is intensively present in her works from her earlier texts until her last writings. This can be explained by the fact that, for this author, it is through time that we can access to reality and find any sense into the latter. That being said, our goal is to show that, if certainly it can be affirmed that S. Weil’s conception of time in her maturity years is constructed from a spiritual, mystic and religious perspective, at the opposite, in her first period, the philosopher settles her views through an ontology strong influenced by Kant, which conducts her to limited temporal matters into the frame of possible experience, according to the definition of this expression given by the German thinker.

Resumen: En este trabajo estudiamos la génesis de la concepción de la percepción de Simone Weil. Apoyándonos en algunos textos clave de juventud de la autora, hacemos el seguimiento al manejo que le da la filósofa a la figura mitológica de Proteo y a las nociones de tiempo y espacio. Así, nuestra intención es evidenciar la aparición de los principales fundamentos teóricos que estructurarán la fenomenología weiliana de los años de madurez.2 En este sentido, intentamos demostrar en particular que si (...) bien el proceso perceptivo weiliano de los años de juventud está determinantemente influenciado por la fenomenología kantiana, aparece ya un aporte original en lo que atañe a la relación de la conciencia del sujeto y los datos espaciotemporales que se le revelan al aprehender el objeto.: In this work we study the genesis of Simone Weil's conception of perception. We discuss her use of the notions of time, space, and the mythological figure of Proteus, analyzing some of the author's key early texts. Our goal is to then make clear the appearance of the main important theoretical bases that organize Weil's phenomenology in her mature years. In this way, we try to demonstrate that although the perceptive process as conceived by the young Weil is strongly influenced by Kantian phenomenology, it already appears as an original contribution with regard to the relation between the consciousness of the subject and the spatiotemporal data revealed in the apprehension of the object.

The counterfactual thinking cannot be only developed in early childhood, but it also could be a requirement for the causal reasoning. In this research a replica of German was made using counterfactual stories with Latin American kids between three and four years, demonstrating the possible main role counterfactual reasoning, by using computer animations. This was a different approach to the most recent made by Nyhout and Ganea. Nonetheless, the participants of the study evidenced counterfactual reasoning to the relevant choice and (...) the negative consequence conditions shown on the stories that represented the choices made by a starting role. Although some of the results were not totally conclusive under the analyzed conditions. Lastly, some possible not controlled effects are discussed from stories shown to the children, that could have motivated the counterfactual thinking. (shrink)

_This article presents the main ethical challenges faced by social work professionals in Spain during the "first wave" of COVID-19 in 2020. The pandemic had a serious impact not only on the health sector, but also in the field of social work. During this time, social workers had to address serious ethical questions regarding issues such as confidentiality breaches, how to fairly distribute available resources, the lack of personal contact and emotional connection with the service users, the difficulties of working (...) in isolation and online, doubts about the reliability of the information they were handling and the difficulty of making proper diagnoses. An international research group led by Dr. Sara Banks conducted a broader research project in collaboration with the International Federation of Social Workers, which collected information through an online questionnaire aimed at social workers from various countries. In this article we analyse the results related to the main ethical challenges faced by social workers in Spain. The research group identified two types of ethical challenges that they have separated into two sections: the first section is related to direct intervention with users, which includes topics such as the lack of emotional support, reliability, use of technology, the appropriate care, compliance with the highest professional standards, confidentiality, vulnerability, and the fair distribu-tion of resources. The other section is related to the ethical challenges around the daily work within social entities, which involved dealing with issues such as the e-social work and coordination difficulties, the management of pressure in social bodies and changes in the intervention methodology__._ _Keywords_: Social work ethics, pandemic, international research, COVID.

La vida en el futuro a corto plazo será revolucionada por el efecto creciente de tecnología multidisciplinaria en todas las dimensiones: social, económico, político, y personal. La revolución de disponibilidad de la información y utilidad seguirá afectando en profundidad el mundo en todas estas dimensiones. Los resultados serán asombrosos. Los efectos pueden incluir mejoras significativas de la calidad de vida, las altas tarifas de volumen de ventas industrial, la globalización continuada, la amalgamación cultural o la epidemia de aislamiento de los (...) individuos, así como el aislamiento personal en una tentativa de hacerse más abiertos mundialmente. La realización real de estas posibilidades dependerá de un número de factores, incluyendo la aceptación local de cambio tecnológico, niveles de inversiones de infraestructura y tecnología.

The revolution of information availability and utility will continue to profoundly affect the world in all these dimensions. The results will be astonishing. Effects may include significant improvements in human quality of life, high rates of industrial turnover, continued globalization, cultural amalgamation or invasion of individuals’ privacy, as well as personal isolation in an attempt to become more open worldwidely. The actual realization of these possibilities will depend on a number of factors, including local acceptance of technological change, levels of technology and infrastructure investments. The fast pace of technological development and breakthroughs makes foresight difficult, but the technology revolution seems globally significant and quite likely. (shrink)

We investigate whether age profiles of ethnobiological knowledge development are consistent with predictions derived from life history theory about the timing of productivity and reproduction. Life history models predict complementary knowledge profiles developing across the lifespan for women and men as they experience changes in embodied capital and the needs of dependent offspring. We evaluate these predictions using an ethnobiological knowledge assessment tool developed for an off-grid pastoralist population known as Choyeros, from Baja California Sur, Mexico. Our results indicate that (...) while individuals acquire knowledge of most dangerous items and edible resources by early adulthood, knowledge of plants and animals relevant to the age and sex divided labor domains and ecologies (e.g., women’s house gardens, men’s herding activities in the wilderness) continues to develop into middle adulthood but to different degrees and at different rates for men and women. As the demands of offspring on parents accumulate with age, reproductive-aged adults continue to develop their knowledge to meet their children’s needs. After controlling for vision, our analysis indicates that many post-reproductive adults show the greatest ethnobiological knowledge. These findings extend our understanding of the evolved human life history by illustrating how changes in embodied capital and the needs of dependent offspring predict the development of men’s and women’s ethnobiological knowledge across the lifespan.

We define a multi-modal version of Computation Tree Logic ( ctl ) by extending the language with path quantifiers E δ and A δ where δ denotes one of finitely many dimensions, interpreted over Kripke structures with one total relation for each dimension. As expected, the logic is axiomatised by taking a copy of a ctl axiomatisation for each dimension. Completeness is proved by employing the completeness result for ctl to obtain a model along each dimension in turn. We also (...) show that the logic is decidable and that its satisfiability problem is no harder than the corresponding problem for ctl. We then demonstrate how Normative Systems can be conceived as a natural interpretation of such a multi-dimensional ctl logic. (shrink)
