Para ello, el primer apartado de este trabajo se centra en analizar investigaciones previas con la intención de comprender después las estrategias persuasivas emocionales de Greta, presentes en los discursos analizados. Todo ello, servirá de base para una propuesta de innovación docente para alumnos de tercer y cuarto curso con el fin de iniciarlos en el Análisis Crítico del Discurso siguiendo un enfoque de Enseñanza Comunicativa de la Lengua en la adquisición de la L2. Para ello, se propone una metodología donde el profesor sea el primero que analice, simplifique y reflexione sobre los textos empleados. De este modo, se pretende ayudar a los alumnos a tomar conciencia del problema climático existente, a la vez que se abordan los Objetivos de Desarrollo Sostenible (ODS) de la Agenda 2030.<br /

    Towards Supercomputing Categorizing the Maliciousness upon Cybersecurity Blacklists with Concept Drift

    Get PDF
    [EN] In this article, we have carried out a case study to optimize the classification of the maliciousness of cybersecurity events by IP addresses using machine learning techniques. The optimization is studied focusing on time complexity. Firstly, we have used the extreme gradient boosting model, and secondly, we have parallelized the machine learning algorithm to study the effect of using a different number of cores for the problem. We have classified the cybersecurity events' maliciousness in a biclass and a multiclass scenario. All the experiments have been carried out with a well-known optimal set of features: the geolocation information of the IP address. However, the geolocation features of an IP address can change over time. Also, the relation between the IP address and its label of maliciousness can be modified if we test the address several times. Then, the models' performance could degrade because the information acquired from training on past samples may not generalize well to new samples. This situation is known as concept drift. For this reason, it is necessary to study if the optimization proposed works in a concept drift scenario. The results show that the concept drift does not degrade the models. Also, boosting algorithms achieving competitive or better performance compared to similar research works for the biclass scenario and an effective categorization for the multiclass case. The best efficient setting is reached using five nodes regarding high-performance computation resources.SIInstituto Nacional de SeguridadPartial support was received from the Spanish National Cybersecurity Institute (INCIBE) under the contract art (83, 203 key: X54

    Transition metal-free [2,3]-sigmatropic rearrangement in the reaction of sulfur ylides with allenoates

    Get PDF
    An unprecedented transition metal free [2,3]-sigmatropic rearrangement involving stabilized sulfur ylides and allenoates has been thoroughly established. The scope and utility of this reaction have been extensively studied resulting in C–C bond formation under mild conditions with greater than 20 examples reported. A highlight of the work is the simple and fully operational process that does not involve the use of carbenes or the associated hazardous and sensitive reagents. The reaction can be performed at room temperature and using an open flask. Interestingly, the new C–C bond formation reaction is gram scalable, and the obtained isomers are readily separable, affording interesting building blocks that can be used in the preparation of complex molecules.Funding for open access charge: Universidad de Málaga

    La presente Tesis Doctoral desarrolla desde la ingeniería gráfica nuevas metodologías para obtener resultados en el tratamiento de la información del patrimonio histórico industrial que permitan su puesta en valor, en especial de los eólicos y oleícolas, y su implementación para su difusión por parte de las administraciones públicas, museos y centros de interpretación interactivos. Para ello, la estructura de la misma se plasma en los siguientes capítulos: El Capítulo 1 revisa el concepto del patrimonio histórico industrial y sus fuentes de documentación, estudiando la evolución del conocimiento a lo largo del periodo histórico industrial y realizando el análisis de uno de los pilares del patrimonio cultural: el paisaje. El Capítulo 2 se centra en las técnicas y metodologías de ingeniería gráfica para la recuperación del patrimonio histórico industrial, completándose con el estudio y perfeccionamiento de las distintas potencialidades que ofrece la ingeniería gráfica en las tareas propias de la disciplina de la arqueología industrial. El Capítulo 3 versa sobre la recuperación de los bienes industriales desde diferentes entornos virtuales, persiguiendo el estudio e implementación de las técnicas de animación por ordenador en el patrimonio histórico industrial, en busca de recreaciones virtuales de carácter realista. El Capítulo 4 muestra la representación de los bienes industriales sobre la superficie terrestre. De esta forma se logra inventarios cuya base es la tecnología de los sistemas de información geográfica y se llevan a cabo análisis geoespaciales cuyo objetivo será la propuesta de rutas turísticas, aplicándose al patrimonio histórico eólico andaluz. El Capítulo 5 parte de la documentación gráfica anteriormente obtenida para someterla a distintos análisis desde la ingeniería, como el estudio clásico eólico o los análisis por elementos o volúmenes finitos, resultando nuevo conocimiento técnicotecnológico del patrimonio histórico industrial...The present Ph.D. Thesis develops new engineering graphics methodologies to increase the value enhancement of historical industrial heritage information. Research applications have focused on windmill and olive oil heritage in order to their implementation for dissemination by public administrations, museums and interactive interpretation centers. Therefore, this Ph.D. Thesis is structured in the following chapters: Chapter 1 reviews the concept of historical industrial heritage and its documentation sources. Knowledge evolution is analyzed along the historic industrial period and landscape is assessed as one of the foundations of the cultural heritage. Chapter 2 focuses on the techniques and methodologies of engineering graphics to recover the historical industrial heritage. Several potentialities based on normal discipline tasks of industrial archeology are studied and improvement by engineering graphics. Chapter 3 deals with the recovery of industrial properties from different virtual environments. Computer virtual techniques are studied and implemented on virtual realistic recreations and immersive environments in the historical industrial heritage. Chapter 4 shows the representation of industrial properties over land surface in order to generate windmill inventory based on geographic information system technologies. A geospatial analysis is performed with the main aim to propose tourist routes applied to Andalusian windmill heritage. Chapter 5 analyzes the previously graphic documentation obtained under an engineering perspective, as classic wind study, finite and volume elements analysis. The result is a new technical-technological knowledge of historical industrial heritage. Chapter 6 develops three specific areas for the results divulgation to make proposals for cultural tourist routes. These areas are based on a standardization of educational resources applied to industrial archaeology by engineering graphics. Additionally, information flow diagram for a suitable virtual museum is proposed to public administration, on-site museums or interactive interpretation centers..

    Scarcity climate rents under a carbon price with oligopoly competition

    Get PDF
    Prior research has shown that environmental policy can create scarcity rents. We analyse this phenomenon in the framework of a duopoly that faces a carbon price, considering both Cournot and Stackelberg competition. We identify the different sources of scarcity rents, which we classify in ‘output’ and ‘grandfathering’ scarcity rents. The former depend on the elasticity of the rivals’ output to the carbon price, while the latter is exogenous. We also determine under which conditions these rents can be large enough to increase firms’ profits and, as a policy implication, to what extent the existence of scarcity rents can make the firms agree on a tougher policy. This event is more likely to happen under Cournot than under Stackelberg competition, and the chances increase if the firms are allowed to pollute a large amount without paying a price

    Effects of advertising on problem gambling: Neural-cue reactivity as a possible underlying mechanism

    Get PDF
    Problem gambling has recently been reclassified as a non-substance-associated behavioral addiction. To the associated vital impact (family, social, labor, and economic), we must add its increasing incidence in recent years, which has led to prioritizing the problem from the point of view of public health. Although the effects of advertising on gambling behavior have been explored since the second half of the twentieth century, there is a lack of research regarding its underlying mechanisms. Thus, the objective of this review is to present an update on the effects of advertisements on gambling attitudes and behavioral intentions, as well as to present the neurobiological correlates of gambling-related cues as a possible hypothesis for this effect. Advertisements in various formats may act both as a precipitating factor and as a maintenance factor for the gambling disorder, changing both attitudes and beliefs about gambling. Activation of brain areas related to reward, such as accumbens nucleus, to memory, such as hippocampus or amygdala, and to executive functions could be the underlying mechanism of this effect. Also, ads promoting responsible gambling do not appear to be effective in reducing behavior or encouraging self-control, but the available evidence is scarce. Therefore, the number of studies on this topic needs to increase. In addition, the available evidence questions the effectiveness of responsible gambling policies to promote self-control in this population, as well as to reduce the negative impact of this disorder, so future research on neural-cue reactivity to gambling-related stimuli may serve to improve the design of advertising strategies that increase the impact of these messages
