En este trabajo el autor defiende la necesidad de completar la distinción entre permisos fuertes y débiles con otras dos distinciones: una de ellas relativa también al sistema jurídico –la distinción entre permisos protegidos y permisos no protegidos– y la otra relativa al proceso de aplicación del derecho: la distinción entre permisos prima facie y permisos concluyentes. El trabajo concluye con un cuadro en el que, sobre la base de estas tres distinciones, se recogen ocho combinaciones posibles a distinguir en (...) materia de permisos. (shrink)

Prispevek kritično obravnava znano Bobbievo tridelbo pravnega pozitivizma na pozitivizem kot splošni pristop k učenju prava, nauk o pravu in ideologijo. Avtor uvodoma opozori na nekaj problemov same tridelbe, nato pa se osredotoči na Bobbievo samoopredelitev znotraj nje. Na primeru Bobbieve obravnave pojmov temeljne norme in pravila priznavanja pokaže, kako ga njegovo kasnejše zavračanje teh dveh pojmov nezavedno privede do sprejemanja pravnega pozitivizma kot nauka o pravu in pravne ideologije – ki ju je sicer zavračal. Avtor vidi razlog za ta (...) nezavedni Bobbiev zdrs predvsem v njegovi vpetosti v specifično pravnokulturno okolje, ki ga prežema notranji pogled na pravo. Ob tem predlaga, da zavrnemo tridelbo pravnega pozitivizma in ga namesto tega proučujemo kot skupek ne vedno ločljivih stališč, ki tvorijo specifično pravnokulturno okolje. (shrink)

El autor llama unilateralismo a la presentación de nuestros sistemas de normas e instituciones como si obedecieran a un único valor inspirador. El unilateralismo, en este sentido, implica la negación, explícita o implícita, de que tales normas e instituciones están atravesadas por tensiones internas que obedecen a que tratan de realizar valores que se encuentran, a su vez, en tensión entre sí. En el artículo se examina la posición de Luigi Ferrajoli en relación con cuatro ámbitos en los que, a (...) juicio del autor, dicha posición es unilateralista en el sentido indicado: primero, el de la relación entre constitución y legislación; segundo, el de la distinción entre principios y reglas; tercero, el de la opción por un determinado sistema electoral; cuarto, el del problema de la guerra. Este unilateralismo desemboca, a juicio del autor, en una presentación distorsionada por parte de Ferrajoli de los problemas de estos cuatro ámbitos. (shrink)

El objeto de este trabajo es el de dar cuenta de las críticas a Kelsen contenidas en el último libro, todavía inédito, de Luigi Ferrajoli, Diritto e logica. Dieci aporie nell’opera di Hans Kelsen, y formular algunas críticas a las tesis sostenidas en él por el propio Ferrajoli. Entre las críticas que el autor considera que cabe dirigir a este respecto a Ferrajoli, las principales afectan al carácter exclusivamente interno de la mirada ferrajoliana sobre el derecho, al carácter siempre opinable, (...) y nunca verdadero o falso, que, según Ferrajoli, tienen los enunciados interpretativos, y a la incompatibilidad que, según el autor, se presenta entre las ambiciones de la teoría ferrajoliana y las limitaciones que a la misma impone su anclaje en el no cognitivismo ético.

The paper critically examines Bobbio's famous disctinction between legal positivism as a method, a theory and an ideology. The author first highlights certain problems of the distinction itself and then focuses on Bobbio's self-determined position within it. Delving on Bobbio's analysis of the concepts of basic norm and rule of recognition, he demonstrates how Bobbio's later rejection of these two concepts implies acceptance of positivistic legal theory and ideology – despite the fact that he explicitly rejected them in the first (...) place. The reason for this Bobbio's slip is found in his absorbtion in the positivist legal culture which is permeated with the internal point of view on the law. The author suggests rejecting Bobbio's tripartite disctinction of legal positivism and proposes instead to view this as a set of seldom indvisible standpoints forming a specific legal culture.

In the first part of the paper the authors analyze how the distinction between mandatory rules, principles in the strict sense and policies can be understood in structural terms and in terms of reason for action. In the second part, they attempt to clarify which kind of legal provisions embrace constitutional statements recognizing liberty rights are.

En este artículo analizamos la cuestión de la presencia del mundo en los escritos de juventud de Simone Weil, con el objetivo de aprehender su concepción del tiempo. En ese sentido, intentaremos elucidar las relaciones ontológica y epistemológica que ella establece entre el hombre y el mundo. Esta perspectiva nos permite explorar la primera filosofía de la percepción weiliana y trazar las implicaciones existenciales que se desprenden de la experiencia del presente. Igualmente, examinamos la dificultad de pensar la inmovilidad en (...) la realidad humana a partir de la tensión problemática que plantea S.Weil entre las nociones de continuidad y eternidad. Palabras clave: Simone Weil, presencia, mundo, continuidad, eternidad, tiempo. (shrink)

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 Mexico, the Productive Organization Program for Indigenous Women (POPMI) seeks the empowerment of productive capacities in indigenous women. Our study analyzes POPMI outreach, focusing our attention on women beneficiaries who present a high degree of social exclusion and multidimensional poverty in the State of Veracruz. In the study area, the 542 indigenous women benefited in POPMI, presented a condition of multidimensional poverty and a degree of social exclusion: very high, high and medium, they represent only 22.19% of the total (...) beneficiaries of this program In 2010, since at the state level a total of 2,243 indigenous women were cared for. The results show that the localities where the condition of multidimensional poverty and very high, medium and high levels of social exclusion have been excluded in the coverage of POPMI. (shrink)

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.

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: 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.

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)

La relación entre el fenómeno religioso y el marco de la secularidad o la postsecularidad se hace presente en el ámbito de la escuela pública y, en cierta medida, reproduce las tensiones que tiene la sociedad a la hora de situar esa relación. El objetivo de este texto es presentar y valorar esa relación en el caso español, el cual posee un modelo de tipo confesional de la enseñanza de la religión en la escuela pública. La descripción del modelo debe (...) tener en cuenta el contexto histórico particular y su aplicación, que ha tenido variaciones significativas a lo largo del período democrático según los gobiernos de turno. Se trata de una opción muy controvertida que requiere una valoración ponderada, de tal manera que el texto sumaría los aspectos positivos y las dificultades que suscita el modelo en general y, en particular, la concreción española. La controversia tiene aspectos más coyunturales y otros de mayor calado, cuyo tratamiento sugiere una reflexión de tipo antropológico y teológico, la cual se realiza de manera incipiente. (shrink)

Durante la última década se ha producido un importante desarrollo de prácticas que formulan propuestas alternativas a los modos de producción, consumo e intercambio dominantes. Este artículo analiza el tejido de prácticas económicas alternativas en la ciudad de Valladolid, una ciudad media alejada de los contextos urbanos sobre los que se ha construido el cuerpo teórico que indaga en el potencial transformador de redes de consumo, mercados de trueque, bancos de tiempo, monedas sociales o huertos comunitarios. El trabajo, consciente del (...) valor del contexto y de la escala, propone para ciudades como la estudiada una relectura que sitúa dicho potencial no en el ámbito económico, sino en el de la práctica y la experiencia social y en el de la cultura política.The last decade has witnessed an important development of practices that involve alternative proposals to the dominant production, consumption and exchange patterns. In the present article, we present an analysis of the interwoven patterns of alternative economic practices in Valladolid, a mid-sized city in Spain. This urban profile differs from the cities that have typically been used to design the body of research on the transformation power that consumer networks, bartering, time banking, social coin and community orchards have. Taking into account the value of both the context and the scale under investigation, this study proposes a reanalysis for these types of cities: under this view, the potential is not placed in the economic sphere but rather in the social practice and experience as well as in the political culture.

Parecería haber una oposición entre el amor a sí mismo, el amor a los demás y el amor a Dios. Por un lado, el amor sui deviene en un egoísmo individualista; por otro, se olvida de sí mismo para entregarse desinteresadamente a los otros. Sin embargo, un análisis profundo de estos distintos amores, como el que nos proponemos en este trabajo, siguiendo las huellas de santo Tomás, muestra su profunda armonía e integración.
