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)

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.

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)

Relativamente ao ius gentium deparamo-nos com três questões relacionadas: existe na antiga Roma um Direito internacional? Pode dizer-se que sim em dois aspectos: ao estabelecer-se o direito das embaixadas e da guerra e ao regular os pactos internacionais. Internamente, contudo, existirá um directo étnico, um reconhecimento e um respeito pelas diferenças culturais que se verificavam entre as diversas nações e cidades do Orbe? E, mais concretamente, até que ponto é que Roma era tolerante com as diversas religiões das distintas culturas (...) ou, então, proselitista? O ius gentium aplica-se a cada um destes níveis. Estudamos o caso da relação Roma-Gades e os dados com que contribui para a resolução destas questões. (shrink)

Uno de los grandes problemas que enfrenta la educación en la actualidad, radica en el hecho de que los profesores de pronto se ven invadidos, y en su caso, obligados a utilizar las computadoras, los dispositivos móviles e Internet en el salón de clase. La falta de programas efectivos de capacitación y formación docente en el uso y aplicación de las TIC en los procesos de enseñanza aprendizaje, se ha convertido en un problema de grandes dimensiones que alcanza prácticamente a (...) todos los niveles educativos. Ante tal escenario, el presente trabajo pretende la adopción por parte de los profesores, de una herramienta que les sea de utilidad para orientar su formación en el campo de las TIC: “El árbol diagnóstico de las competencias digitales”, el cual ofrece un panorama general acerca de los recursos informáticos y de la Web que hemos identificado como relevantes en el ejercicio de la docencia. Este “árbol diagnóstico” es el resultado de un proceso de evaluación y seguimiento llevado a cabo con grupos de profesores que ya utilizan la tecnología en su práctica docente; y tiene la finalidad de orientar y facilitar el aprendizaje autónomo de los profesores que se inician en el uso de las TIC.

La evolución del rol del profesor en las aulas en las dos últimas décadas se ha destacado por la preocupación de cumplir con las grandes exigencias de las instituciones educativas: adquirir habilidades digitales que les permita alcanzar un nivel “óptimo” de conocimiento en el uso de los recursos tecnológicos informáticos e incorporar estos recursos en sus actividades en el aula. No obstante, aún no se encuentra la fórmula para que los profesores modifiquen el modelo de enseñanza (transmisor-receptor) vigente en las (...) escuelas y en el salón de clase. Sin embargo, aunque las actividades que se realizan en el aula se encierran en una aparente caja negra, en este trabajo se presentan modelos tecno-pedagógicos que han implementado profesores de educación superior en el aula y que propone un nuevo rol del profesor, el docente innovador. Un profesor que combina el curriculum, contenidos, didácticas, actitudes, habilidades digitales, y estilos de aprendizaje para innovar en su método didáctico y que da cuenta de su habilidad didáctica, su conocimiento y preparación profesional así como de una cultura digital que va más allá de saber usar los dispositivos digitales y que conjunta los saberes humanos y tecnológicos en un modelo tecno-pedagógica para construir nuevos entornos de aprendizaje y modelos de enseñanza.

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.

Manifiesto del águila y la serpiente.--Dialéctica mundial.--Ser y significado de la filosofía.

En 1670, el autor español Juan Caramuel publicó en Italia el segundo tomo de una magna obra, Mathesis biceps (publicada en latín), sobre el saber matemático de su época. En el mismo se incluía un capítulo (un "sintagma" según el propio Caramuel), titulado Kybeia ("juegos de dados" en griego), donde el autor introduce su idea del origen del juego y resuelve algunos problemas relacionados con los mismos, convirtiéndose en una de las obras tempranas sobre cálculo de probablidades. En este texto (...) se da un repaso a los antecedentes al trabajo de Caramuel relacionados con el cálculo de probabilidades, se analiza punto por punto la aportación de este autor al nuevo cálculo en su Kybeia, y se añade la traducción al castellano del mismo.

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)

Resumen: En este artículo se presentan los resultados iniciales del análisis del fenómeno del habla ascendente registrada en enunciados en foco amplio en seis hablantes monolingües de español y seis hablantes nativos de mapudungun con manejo funcional de español de la IX Región. Se analizaron acústicamente los fragmentos entonativos de los primeros cinco minutos de conversación de los hablantes bilingües para describir las alturas tonales de las sílabas nucleares y postnucleares. Estos se compararon con los enunciados equivalentes de hablantes monolingües. (...) Los resultados expresados en notación fonológica y en semitonos muestran una tendencia a un mayor ascenso tonal en hablantes de la zona precordillerana en comparación con hablantes de zonas rurales más próximas a la capital de la Región.: This paper presents preliminary outcomes of the analysis of the rising tone phenomenon found in utterances with a wide focus produced by six monolingual Spanish speakers and six native speakers of Mapudungun who have a functional command of Spanish, all of them from Región de La Araucanía in Chile. The intonational phrases of the five first minutes of conversation with native speakers were analyzed in order to describe the pitch of nuclear and postnuclear syllables. These were later compared with equivalent utterances produced by monolingual speakers. The outcomes, expressed in phonological notation and in semitones, show a tendency to a higher tone rise in speakers from the foothills of the Andes mountain range as compared with speakers from rural areas located nearer the capital of the Region.

Previous research has shown positive relationships between fitness level and different cognitive abilities and academic performance. The purpose of this study was to explore the relationships between logical–mathematical intelligence and mathematical competence with physical fitness in a group of pre-adolescents. Sixty-three children from Castro del Río, aged between 11 and 12 years, participated in this research. The Superior Logical Intelligence Test and the EVAMAT 1.0–5 battery were used. Physical fitness was evaluated by the horizontal jump test, the 4×10 meter speed–agility (...) test, and the Course Navette test. The analyses showed positive relationships between physical fitness with logical–mathematical intelligence and mathematical competence. Specifically, linear regression analyzes indicated that the 4×10 speed–agility test significantly predicted mathematical competence and the horizontal jump test significantly predicted logical–mathematical intelligence. These results are in agreement with previous research, highlighting the importance of improving physical fitness from an early age due to its benefits for intellectual and academic development.

Cancer is a chronic disease that causes the most deaths in the world, being a public health problem nowadays. Even though breast cancer affects the daily lives of patients, many women become resilient after the disease, decreasing the impact of the diagnosis. Based on a positive psychology approach, the concept of co-vitality arises understood as a set of socio-emotional competencies that enhance psychological adaptation. In this sense, emotional intelligence is one of the main protective factors associated with resilience. However, it (...) is not always as beneficial as it seems, and can lead to collateral effects on psychological adjustment. Given this controversy, this study aims to find the specific processes through which the dimensions of Perceived Emotional Intelligence can act as a risk or protective factor in the development of resilience. The total sample was 167 women, 46.7% were breast cancer survivors, and 53.3% were healthy controls. The selection of women with breast cancer carries out randomly, recruited through the Oncology Units. The sample completed measures of resilience and PEI, through Resilience Scale and TMMS-24. The results showed that breast cancer survivors showed higher age and greater levels of resilience and mood repair than healthy women. The mediation analysis revealed that breast cancer survival and PEI predicted 28% of the variance of resilience. The direct effects showed that emotional clarity and mood repair increased resilience levels. Although breast cancer did not predict resilience directly, it does through mood repair by an indirect process. Besides, the analysis showed that emotional attention played a role in vulnerability, decreasing mood repair, and resilience. These research support theories that point to a possible dark side of PEI, thus, a great level of emotional attention makes dark the positive effect of mood repair and personal growth if a clear perception of emotions does not complement it. These results provide empirical support concerning the need to work complementary each dimension of PEI to avoid unwanted effects on intrapersonal adjustment. (shrink)

Innovation and sustainability are postulated as key variables for the future of large commercial distribution. In addition, the development of Information and Communication Technologies solutions, and especially those related to Artificial Intelligence and digitization, are particularly relevant factors in the current pandemic scenario in which retail companies operate. These tools are essential to face the derived changes in commercial relations, especially between companies and consumers. For all these reasons, this work aims to examine the effect of ICT, as a driving (...) factor for innovation and its direct and indirect impact on sustainability in retailing. Furthermore, this study takes into account the eventual differences in these relationships according to the types of store formats. To achieve the aforementioned objective, a theoretical model is proposed that is tested through an empirical study carried out on a sample of 510 consumers of three store formats of grocery retail formats in Spain. For the analysis of the data obtained, the partial least squares regression technique and the Multigroup Analysis were used. The results obtained confirm the direct and indirect effect of ICT on innovation and sustainability in grocery retailing. In addition, the results indicate that consumers unequally perceive the technological progress of companies. These differences are greater between discount stores versus hypermarkets and supermarkets. The larger the size of the store format, the higher the incidence of ICT in relation to innovation. Therefore, it is vital to take ICT into consideration, where Artificial Intelligence is imperative for the growth and development of sustainable competitive advantages in retail companies. (shrink)

Training for sustainable development is an educational challenge of prime importance. Physical activity and sports in natural environments provide training committed to sustainability and environmental education. The objective of this study was to assess the effects of an undergraduate training program in Physical Activities and Sports in Natural Environments concerned with sustainable development. A total of 113 students from the Autonomous University of Madrid who are studying a Bachelor’s Degree in Physical Activity and Sports Sciences and a Master’s Degree in (...) Teacher Training for Secondary Education and High School were involved. Specifically, we aimed to assess the impact of this training program on three dimensions related to Environmental Education. Its effect was also examined bearing in mind students’ sex, age and educational profile. Mixed-methods were used: for the quantitative approach, data were collected with the Environmental Attitude in Physical Activities in Natural Environments validated scale; for the qualitative approach individual reflective diaries completed by students that attended the program were analyzed. The results show positive effects on the students regarding the three dimensions of Environmental Education, for both the sportive and educational training profiles. The quantitative results do not present significant differences concerning the gender variable, although the qualitative information shows that female students perceived a greater environmental sensitivity during their practices. Regarding the age variable, significant differences are found in the youngest students with an educational profile. To conclude, the study ratifies that the program carried out generated improvements in terms of knowledge, behaviors and attitudes toward the environment and sustainable development. Future research should use larger samples and consider other variables related to education for sustainability. (shrink)
