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)

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)

We present the resistive switching characteristics of Metal-Insulator-Metal devices based on amorphous Al2O3which is deposited by Atomic Layer Deposition. A maximum processing temperature for this memory device is 300°C, making it ideal for Back-End-of-Line processing. Although some variations in the forming, set, and reset voltages are obtained for many of the measured MIM devices, thememristoreffect has been obtained after cyclicI-Vmeasurements. These resistive transitions in the metal oxide occur for bothbipolarandunipolarconditions, while theIOFF/IONratio is around 4–6 orders of magnitude and is formed (...) at gate voltages ofVg<4 V. In unipolar mode, a gradual reduction inVSETis observed and is related to combined incomplete dissolution of conductive filaments which leaves some residuals and thickening of chemically reduced Al2O3during localized Joule heating. This is important because, by analyzing the macroscopic resistive switching behavior of this MIM structure, we could indirectly relate it to microscopic and/or nanoscopic phenomena responsible for the physical mechanism upon which most of these devices operate.

El desarrollo de la tecnología y de la inteligencia artificial provocan desde hace años preguntas éticas y antropológicas. La Suma Teológica de Santo Tomás permite categorizar términos tecnológicos y establecer ontologías en clave filosófica. Con esta metodología de la Suma se va a estudiar aquí el término “metaverso” y sus implicaciones éticas. El artículo aporta además una revisión sistemática de literatura científica para elaborar un mapa de conocimiento desde un punto de vista cualitativo y cuantitativo que visibilice el impacto de (...) esta terminología emergente en la investigación.

We present nine facets for the analysis of the past and future evolution of AI. Each facet has also a set of edges that can summarise different trends and contours in AI. With them, we first conduct a quantitative analysis using the information from two decades of AAAI/IJCAI conferences and around 50 years of documents from AI topics, an official database from the AAAI, illustrated by several plots. We then perform a qualitative analysis using the facets and edges, locating AI (...) systems in the intelligence landscape and the discipline as a whole. This analytical framework provides a more structured and systematic way of looking at the shape and boundaries of AI. (shrink)

In the article we carry out a reading of the dossier on Herculine Barbin, a 19th century hermaphrodite who commits suicide at the age of 29 after having been legally reassigned to the "opposite sex", which Michel Foucault recovered from the medico-legal annals of the XIX century and published in 1978. A reading that emphasizes the subjective and experiential nature of Herculine's memoirs, as well as the critical nature that Foucault attributes to them and how this allows him to question (...) the idea that there is a "true sex" and, therefore, a “legitimate sexual identity”. Based on the above, we strive to show how the memories show the violent functioning of the binary regime of sexuality and the heteronormative character of the "sex-gender continuum", which allows us to recover the relevance of the project of a "desexualization of the pleasure” that Foucault used as the radical political strategy that would allow us to arrive at a new, fuller and freer economy of the body and its pleasures.

La Segunda Guerra Mundial y las atrocidades cometidas en investigaciones con los prisioneros en los campos de concentración nazis y japoneses, despertaron la conciencia por el desarrollo de los derechos humanos que se habían conquistado paulatinamente a lo largo de la historia. Por ello se conforman una serie de leyes, normas y declaraciones donde se tratan los aspectos bioéticos en los ensayos clínicos. Se debe prestar vital atención a la relación médico-paciente en el curso de las investigaciones y considerar la (...) relación beneficio/riesgo cuando se va a experimentar en seres humanos. La retinopatía diabética proliferativa es una de las afecciones oftalmológicas que más ensayos ha suscitado. El objetivo de este trabajo consiste en analizar algunos aspectos éticos en la experimentación en pacientes con esta afección. The Second World War and the atrocities committed in research with prisoners in Japanese and Nazi concentration camps, awakened consciousness for the development of human rights that had gradually been conquered throughout history. That´s why a series of laws, rules and statements that deal with bioethical aspects in clinical trials, were passed. Special attention must be given to the doctor-patient relationship during the research and consider the benefit/risk ratio when conducting experiments on human beings. Proliferative Diabetic Retinopathy is one of the ophthalmological disorders that has given rise to more trials. The research goal is to analyze some ethical aspects when experimenting on patients with this condition. (shrink)

The distinctive security features of the Spanish electronic national identity card, known as Documento Nacional de Identidad electrónico, allow us to propose the usage of this cryptographic smart card in an authentication framework that can be used during the registration and login phases of internet services where the validation of the user’s age and real identity are key elements, as it is the case for example of the so-called social networks. Using this mechanism with NFC-capable devices, the identity and age (...) of the potential user can be determined, allowing or denying the access to the service based on that information. (shrink)

Introduction: Resilience is a multidimensional and dynamic construct associated with positive growth and the capacity to transform stressful and negative factors into opportunities of personal development and self-improvement when faced with difficult experiences. The resilience process of each individual integrates multiple analysis levels, which range from genetic-environmental interactions to a complex process of adaptation between the individual and his/her family, friends, co-workers, society, and culture.Objective: To determine whether resilience improves in students of occupational therapy when exposed for the first time (...) to practice placement education.Methodology: Quasi-experimental, prospective, observational, multi-center study with a sample composed of students from the Degree of Occupational Therapy of the public universities of Málaga and Castilla-La Mancha. Two weeks prior to the beginning of the practice education period, the participants completed a questionnaire that included sociodemographic data and the area of their internships. They were also given the Spanish version of the Connor-Davidson's resilience scale. All these instruments were also completed 1 week after the end of the clinical practice.Results: There were statistically significant differences between the variables that make up resilience and the different internship areas. On the other hand, there was a significant improvement of global resilience after the clinical practice period, in both women and men, when the internship area was not considered.Conclusions: The results show that resilient students are more optimistic and work to improve a situation beyond doing simply what is expected of them, knowing how to control their feelings. This is beneficial for students in practice education, since, during these, they face difficult situations that require a resilient pattern, which helps reduce stress and the burnout syndrome.

The aim of this article is to analyse the opinions of journalists and citizens regarding the interdependence of public media and the official sources of political power in Spain. Little research of this kind has been done in the Spanish context. Journalists and citizens representing four Spanish regions?Catalonia, Madrid, the Basque Country, and Andalusia?were questioned about their opinions regarding this interdependency. The methodology used in this research is based on quantitative techniques (surveys) and qualitative techniques (in-depth interviews and focus groups). (...) The results prove that the opinions of journalists differ from those of citizens for the majority of questions asked. Citizens are more inclined to follow directions from official sources than are journalists. The geographical background of the respondents proved to be a significant factor in terms of variation in answers. Journalists from Catalonia and the Basque country are much more reluctant to follow government directives on issues of counter terrorism or in cases of national emergency. (shrink)

Background: COVID-19 has taken many lives worldwide and due to this, millions of persons are in grief. When the grief process lasts longer than 6 months, the person is in risk of developing Complicated Grief Disorder. The CGD is related to serious health consequences. To reduce the probability of developing CGD a preventive intervention could be applied. In developing countries like Mexico, the psychological services are scarce, self-applied interventions could provide support to solve this problem and reduce the health impact (...) even after the pandemic has already finished.Aims: To design and implement a self-applied intervention composed of 12 modules focused on the decrease of the risk of developing CGD, and increasing the life quality, and as a secondary objective to reduce the symptomatology of anxiety, depression, and increase of sleep quality. The Intervention Duelo COVID follows the principles of User Experience and is designed according to the needs and desires of a sample of the objective participants, to increase the adherence to the self-applied intervention, considered one of the main weaknesses of online interventions.Methods: A Randomized Controlled Trial will be conducted from the 22nd of December of 2020 to the first of June 2021. The participants will be assigned to an intervention with elements of Cognitive Behavioral Therapy, Acceptance and Commitment Therapy, Mindfulness and Positive Psychology. The control group will be a wait-list condition, that will receive the intervention 1.5–2 months after the pre-measurement were taken. The Power Size Calculation conducted through G*Power indicated the need for a total of 42 participants, which will be divided by 21 participants in each group. The platform will be delivered through responsive design assuring with this that the intervention will adapt to the screen size of cellphones, tablets, and computers.Ethics and Dissemination: The study counts with the approval of the Research Ethics Committee of the Autonomous University of Ciudad Juárez, México, and it is registered in Clinical Trials. The article is sent and registered in clinical trials before the recruitment started. The results will be reported in future conferences, scientific publications, and media. (shrink)

Alexis de Tocqueville (1805–1859) was convinced that without a new possibility for transcendence, democracies would be ill-prepared to allow for actual freedom. In Democracy in America, his study of the United States, he explained that when self-interest was enlightened, individuals would tend to identify their personal benefits with the well-being of the community. By transcending their individualistic tendency to self-enclose, they would contribute to forming and maintaining a real sovereignty of the people. However, unless the “doctrine of self-interest well understood” (...) was aided by a higher ideal, by itself it would eventually fall short, thus paving the way for new forms of despotism. Religion, and more specifically, reformed versions of Christianity, seemed to effectively elevate the outlook of the early Americans. As I will argue, however, Tocqueville ultimately held that those versions lacked the profundity and stability required to resist the strong materialistic and individualistic tendencies of people living in a democracy. Tocqueville’s apparent, if anxious-ridden, preference for Catholicism as the more adequate civil religion resonates with important aspects of Augustine’s theory of the Two Cities, the earthly and the heavenly city. For both Tocqueville and Augustine, the Roman Church’s stable doctrine was what could more successfully teach mankind the truth about their limited condition, hence making them more capable of learning the “art of being free.”.

This article explores how historical narratives affect the evaluation of political decisions regarding justice during peace negotiations. Specifically, this study evaluates how different narratives of the Colombian armed conflict relate to the preference for either restorative or retributive justice. Results revealed that a historically accurate narrative that included structural elements correlated with the preference for restorative justice, whereas a schematic narrative that focused on individual greed favoured the preference for retributive justice. These results are explained in terms of the characteristics (...) of expert historical narratives, which include structural elements, such as economic and institutional factors. The presence of these elements in the explanation of conflicts decreases the weight of individual decisions and, in this way, prevent ingroup attributional biases. (shrink)

The results indicate that training projects are a strategy aimed at training people who, in a collaborative way and with the support of new technologies, are able to mobilize their knowledge in solving (...) their most pressing context problems, so they differ from traditional educational practices, in which knowledge are transmitted by the teacher in an academic manner. In conclusion, it is necessary to continue carrying out theoretical and empirical studies that enable the educational change required by the society of our time. (shrink)

El propósito de este texto es tematizar la precariedad con las herramientas de la filosofía política. Buscaremos equilibrar horizontes conceptuales con prácticas políticas para pensar la acción democrática en nuestro contexto. Nuestro argumento se compone de cuatro premisas. Primero, que elfalso dilema entre teoría y práctica nos permite explorar una relación de tensión creativa entre ambas para conceptualizar la precariedad. Segundo, que la construcción teórica de la precariedad responde tanto a ideas y conceptos como a instituciones y discursos que configuran (...) las vidas de quienes la experimentan. Tercero, que los distintos usos del concepto de precariedad permiten reconocer una fuente común de vulneración de derechos relacionada con la configuración del trabajo en el orden neoliberal. Cuarto, que relacionar la conceptualización de lo plebeyo con la de lo precario nos permite pensar prácticas democráticas renovadas. (shrink)

The aim of this study was to explore the role of voices as cues to adults of children’s needs for potential caregiving during early childhood. To this purpose, 74 college students listened to pairs of 5-year-old versus 10-year-old children verbalizing neutral-content sentences and indicated which voice was better associated with each of 14 traits, potentially meaningful in interactions between young children and adults. Results indicated that children with immature voices were perceived more positively and as being more helpless than children (...) with mature voices. Children’s voices, regardless of the content of speech, seem to be a powerful source of information about children’s need for caregiving for parents and others during the first six years of life.

We affirm the utility of integrative modeling, according to which it is advantageous to move beyond “one-at-a-time binary paradigms” through studies that position themselves within realistic multidimensional design spaces. We extend the integrative modeling approach to a target domain with which we are familiar, the consequences of bilingualism on mind and brain, often referred to as the “bilingual advantage.” In doing so, we highlight work from our group consistent with integrative modeling.

Identifying the expression of anger in a foreign language and reproducing it appropriately and precisely are skills whose relevance and lack of satisfying proposals have been pointed by research on the pedagogy of emotions (Dewaele, 2010; Toya & Kodis, 1996). This paper combines an identification of lacks in the pedagogy of emotional intonation with an analysis of spontaneous samples of anger as a basis to didactic guidelines for the introduction of the contextualized teaching of anger expression in Spanish. Through colloquial (...) samples, key features for the expression of anger in Spanish are identified. A selection of technical features is adapted in an accessible didactic proposal that is conformed of the stages of identification, induction of recurrent patterns, guided and free production. The proposal offered here is a starting point for the design of didactic units on emotional and expressive speech, an area that lacks didactic guidelines. (shrink)

The topology of DNA duplexes changes during replication and also after deproteinization in vitro. Here we describe these changes and then discuss for the first time how the distribution of superhelical stress affects the DNA topology of replication intermediates, taking into account the progression of replication forks. The high processivity of Topo IV to relax the left‐handed (+) supercoiling that transiently accumulates ahead of the forks is not essential, since DNA gyrase and swiveling of the forks cooperate with Topo IV (...) to accomplish this task in vivo. We conclude that despite Topo IV has a lower processivity to unlink the right‐handed (+) crossings of pre‐catenanes and fully replicated catenanes, this is indeed its main role in vivo. This would explain why in the absence of Topo IV replication goes‐on, but fully replicated sister duplexes remain heavily catenated. (shrink)

Oralia, 17, pp. 7–62) organizada en (...) cinco bloques de factores: funciones de la atenuación, procedimientos lingüísticos de la atenuación, factores estructurales, factores enunciativos y factores situacionales. A partir de esta ficha de trabajo, el propósito de nuestra investigación es considerar la implicación del componente fonoprosódico de la lengua, de modo que nos centramos en el segundo bloque de factores de la ficha indicada. Dicho bloque contiene 22 tácticas lingüísticas de atenuación; de ellas, la táctica 21 se refiere a los elementos prosódicos, paralingüísticos o gestuales y su papel en la expresión de atenuación. Esta táctica, no obstante, debe ser desarrollada para valorar mejor el peso de lo prosódico en la atenuación; se cuenta para ello con la experiencia previa del proyecto Fonocortesía, donde se manejan parámetros segmentales y suprasegmentales relevantes para la expresión de cortesía verbal. El objetivo de este trabajo es, en fin, desarrollar metodológicamente la descripción del componente prosódico en la actividad atenuadora, y precisar a través de parámetros acústicos objetivables en qué pueda consistir ese papel atenuante.

The latest advances in quantum computing forced the National Institute of Standards and Technology (NIST) to launch an initiative for selecting quantum-resistant cryptographic algorithms. One of the best-known proposals is NewHope, an algorithm that was initially designed as a key exchange algorithm. In its original design, NewHope presented a reconciliation mechanism that is complex and represents an entry barrier for potential implementers. This contribution presents equivalent schemes in one, two and three dimensions, which allow anyone to make the transition to (...) the 4D NewHope algorithm easier to undertake. In addition to that, the effect of modifying some of the parameters associated to NewHope’s reconciliation mechanism is studied, which has allowed us to propose different sets of parameters that could increase the security of NewHope implementations.
