The Paralympic Games have become a relevant social and communication tool for the enhancement of global awareness and understanding of disability. The increasing visibility of this kind of global sports event, as well as the efforts of public authorities to make their host cities more accessible, evidence a relevant shift to new urban barrier-free experiences and discourses concerning disability. This research is guided by an exploratory case study approach to assess the disability representation and narratives within the context of the 2020 Tokyo Paralympic Games. The examination of some innovative communication strategies fostering the visibility of disability reveals a series of effective practices implemented in Japan. The focus on the personification of para-athletes, the celebration of public events to experience first-hand para-sports disciplines, as well as the engagement of school-children and young people in para-sports initiatives are predominant in the communication efforts of Tokyo 2020 in the pre-games period.

With a few exceptions, media visibility and representation of people with disabilities is scarce. It is biased and anchored in stigma, distorting their image and hindering their full social participation. Paralympic sport is one of the social fields where the challenge of an objective representation of disability becomes particularly important due to the ever-increasing amount of television attention to the Paralympic Games as a global sports event and some persisting stereotypes in media representation of athletes with disabilities. Through an exploratory and interpretive research method, aimed at assessing media visibility of disability from the perspective of content production and its dissemination, the paper reviews the evolution of media representation of the Paralympic Games and athletes with disabilities during Sochi 2014, Rio 2016, and PyeongChang 2018 global sports events in the daily news programs from the National Spanish Broadcaster, RTVE. The effective inclusion of people with disabilities in the public sphere and a progressive removal of stereotypes and stigma depends to a great extent on the visibility and objective representation of disability in media.

Background Machine learning applications in health care have increased considerably in the recent past, and this review focuses on an important application in psychiatry related to the detection of depression. Since the advent of computational psychiatry, research based on functional magnetic resonance imaging has yielded remarkable results, but these tools tend to be too expensive for everyday clinical use. Objective This review focuses on an affordable data-driven approach based on electroencephalographic recordings. Web-based applications via public or private cloud-based platforms would be a logical next step. We aim to compare several different approaches to the detection of depression from electroencephalographic recordings using various features and machine learning models. Methods To detect depression, we reviewed published detection studies based on resting-state electroencephalogram with final machine learning, and to predict therapy outcomes, we reviewed a set of interventional studies using some form of stimulation in their methodology. Results We reviewed 14 detection studies and 12 interventional studies published between 2008 and 2019. As direct comparison was not possible due to the large diversity of theoretical approaches and methods used, we compared them based on the steps in analysis and accuracies yielded. In addition, we compared possible drawbacks in terms of sample size, feature extraction, feature selection, classification, internal and external validation, and possible unwarranted optimism and reproducibility. In addition, we suggested desirable practices to avoid misinterpretation of results and optimism. Conclusions This review shows the need for larger data sets and more systematic procedures to improve the use of the solution for clinical diagnostics. Therefore, regulation of the pipeline and standard requirements for methodology used should become mandatory to increase the reliability and accuracy of the complete methodology for it to be translated to modern psychiatry.

Augmented Reality (AR) is gaining popularity in educational processes due to its recognized efficacy for teaching and learning. Many studies have identified the trends, advantages, opportunities, challenges, and impact of this technology on education. However, most of the previous studies failed to analyze the pedagogical approaches, somehow ignoring that the success of an intervention depends not only on the technical characteristics of the technology but also on the pedagogical strategies to implement them. This study presents a quantitative meta-analysis of 46 empirical studies to identify, in the light of the learning theories, how pedagogical approaches affect the impact of AR on education. In addition, we analyzed the impact of moderating variables on students' learning outcomes in AR interventions. The results indicate that the highest impact was obtained when interventions employed the collaborative pedagogical approach. Based on the findings of this study, we provide insights for researchers and practitioners on what characteristics of AR interventions seem to benefit students’ learning outcomes and how pedagogical approaches can be applied in various educational contexts, to guide the design of future AR interventions.

Agritourism is a type of ecological tourism that combines agricultural activities with tourism. There is a growing interest in this industry worldwide, which poses both opportunities and challenges for social and natural environments. Grounded on the theory of situated learning, we developed an augmented reality-based educational resource to promote eco-agritourism – namely, to promote agritourism while encouraging tourists to be environmentally responsible. This study presents the results of an educational experiment that compared the scores of students who were instructed using a combination of the augmented reality-based educational resource and the professor's guidance with those of students who were instructed only by the professor. The study analyzed the learning outcomes and the degree of users’ motivation to learn about aquaponics in an agritourism farm. The participants were 40 volunteers who had no previous knowledge about aquaponics. The results show that the resource has a medium effect size on learning gains and a large effect on knowledge retention. Likewise, the data indicates that the resource increased users’ motivation to learn and practice responsible agritourism. These results seem to indicate that augmented reality-based resources are appropriate for promoting eco-agritourism and encourage tourists to develop a positive bond with nature.

Attribute grammars are widely used by compiler-generators since it allows complete specifications of static semantics. They can also be applied to other fields of research, for instance, to human activities recognition. This paper aims to present CAPAS, a Context-aware system Architecture to monitor Physical ActivitieS. One of the components that is present in the architecture is the attribute grammar which is filled after the prediction is made according to the data gathered from the user through the sensors. According to some predefined rules, the physical activity is validated after an analysis on the attribute grammar, if it meets those requirements. Besides that it proposes an attribute grammar itself which should be able to be incorporated in a system in order to validate the performed physical activity.

The main purpose of this work is to model collaborative creative process as multi-agent systems. This will allow the generation of a computational model that can be simulated for assessment of different methods and the analysis of their characteristics, or to create tools that support collaborative creative processes. This paper illustrates how this modeling is done with one example of group brainstorming, Symbolic Brainstorming, which includes many of the features that are common in this type of creative processes. The use of agents to model each of the actors allows modeling heterogeneous individuals, as well as a diversity of interactions and workflows.

Participatory design is a generally accepted practice for the construction of Ambient Assisted Living (AAL) systems. The involvement of experts and users in the conception and design of assistive solutions can lead to better systems. A common technique to involve users is called focus-group, which is mainly a moderated group meeting. Despite its benefits, it cannot be neglected the implicit cost of preparing and performing such meetings, and ensuring, later on, that the resulting assistive solution meets the requirements. A disruptive way to change this situation is the application of ICT technologies. This work contributes with a proposal for partial automation of focus-group techniques that support on-line evaluation of assistive solutions during the conception stage. Also, the paper addresses the formalization of the evaluation feedback through the use of normative systems.

The paper introduces a testing solution for evaluating Ambient Assisted Living systems by means of 3D simulations generated with a game engine, complex event processing, and classifiers. The solution aims to ensure that: (1) some key features of the problem appear in the simulation, and (2) the assistive solution interacts with the persons in the right way. A specific testing solution is needed because of the evolving nature of the simulation (each iteration of the requirements specification involves changes in the activities within the simulation) and the assistive solution (it operates in real time and evaluating its performance may require manually inspecting hours of simulation). The approach is illustrated with a proof-of-concept experiment.

Airport slot allocation is a combinatorial allocation problem involving different complex and autonomous systems. Nowadays, airport slots are allocated in a two-stage process: primary allocation is performed according to a set of administrative rules and for each airport independently, while secondary allocation is based on trading mechanisms. Several studies have raised inefficiencies in these processes. To enhance the airport slot allocation process we use an auction-based market. More specifically, we present an airport slot allocation mechanism based on a price-setting auction that has been implemented and evaluated by means of Agent-Based Modelling (ABM) and simulation techniques. The solutions obtained using our approach are compared and assessed with the ones obtained using linear programing, showing that market mechanisms can be an efficient alternative to the current administrative procedure.

The use of Crowd Simulation for re-enacting different real life scenarios has been studied in the literature. In this field of research, the interplay between ambient assisted living solutions and the behavior of pedestrians in large installations is highly relevant. However, when designing these simulations, the necessary simplifications may result in different ranges of accuracy. The more realistic the simulation task is, the more complex and computational expensive it becomes. We present an approach towards a reasonable trade-off: given a complex and computational expensive crowd simulation, how to produce fast crowd simulations whose results approximate the results of the detailed and more realistic model. These faster simulations can be used to forecast the outcome of several scenarios, enabling the use of simulations in decision-making methods. This work contributes with a simplified faster simulation model that uses a graph of queues for modeling an environment where a set of agents will navigate. This model is configured using Genetic Algorithms (GA) applied to data obtained from complex 3D crowd simulations. This is illustrated with a proof-of-concept scenario where a 3D simulation of one floor of a faculty building, with its corresponding students, is re-enacted in the network of queues version. The success criteria are achieving a similar total number of people in particular floor areas along the simulation in both the simplified simulation and the original one. The experiments confirm that this approach approximates the number of people in each area with a sufficient degree of fidelity with respect to the results that are obtained by a more complex 3D simulator.

Las aplicaciones de impresión 3D para construcción se encuentran en una fase inicial de desarrollo, tanto en lo referente a materiales y piezas como a procedimientos. Dichas limitaciones se deben a la especificidad del sector, el coste de la maquinaria necesaria y una ausencia de un patrón procedimental característico. El artículo presenta una metodología innovadora para superar estas limitaciones mediante un flujo de trabajo sencillo que permita el uso generalista de brazos robóticos mediante software integrativo y un uso de materiales optimizado. Asimismo se expone la integración de diseño y fabricación combinando Sistemas de Integración Robótica y técnicas de Fabricación por Deposición. Finalmente se muestra un modelo de optimización de material y patrones de relleno inteligentes. Se expone una pieza real de 0,4 x 0,4 x 1,5 metros como demostrador tecnológico de gran escala.

Testing the control and deployment of large networks of sensors and actuators is a complex and expensive task. This paper presents a 3D simulation tool that facilitates testing and measuring this kind of systems in a virtual environment, which alleviates the costs of doing these tasks in a physical setting. This is illustrated with an example of how a presence detection system can be designed to monitor the behavior of a crowd under different stimulus. The simulation does not only involve the devices, but provide input data so that they can be decoupled and analyzed separately. This decoupling allows to experiment with different deployments of sensors while the simulation is still working and evaluate their performance in real time. Such feature can be of assistance for decision making when designing a large installation or improving one. The paper contributes with a proof of concept where a large installation, together with its inhabitants, is simulated. The simulation is used then to create different simulations of photoelectric devices that register the proximity of an individual. The results permit to evaluate networks of such devices and think of different configurations without the limitations of the physical environment and the privacy and integrity concerns of individuals.

This paper introduces several cooperative proactive S-Metaheuristics, i.e. single-solution based metaheuristics, which are implemented taking advantage of two singular characteristics of the agent paradigm: proactivity and cooperation. Proactivity is applied to improve traditional versions of Threshold Accepting and Great Deluge Algorithm metaheuristics. This approach follows previous work for the definition of proactive versions of the Record-to-Record Travel and Local Search metaheuristics. Proactive metaheuristics are implemented as agents that cooperate in the environment of the optimization process with the goal of avoiding stagnation in local optima by adjusting their parameters. Based on the environmental information about previous solutions, the proactive adjustment of the parameters is focused on keeping a minimal level of acceptance for the new solutions. In addition, simple forms of cooperation by competition are used to develop cooperative metaheuristics based on the combination of the four proactive metaheuristics. The proposed metaheuristics have been validated through experimentation with 28 benchmark functions on binary strings, and several instances of knapsack problems and travelling salesman problems.

ICARO is an open source platform for the implementation of multi-agent systems (MAS), which provides architectural patterns for several types of agent models, following well established software engineering principles. This paper describes a pattern of cognitive agent, whose main characteristic is to be goal-driven, and its logic described as a rule based system. This has been used in different real projects and as a tool in a master course on the development of intelligent agent applications. Some of these are used to illustrate its use and explain some of the conclusions derived from these experiences, mostly from a software engineer point of view.

Simulation of crowds demands coping with scalability and performance issues that are not usually well supported by general purpose agent based simulation toolkits. On the other side, the use of agent models provides a great degree of flexibility in the specification of the behaviour of the entities and their interactions. The agent architecture that is presented in this work addresses both types of requirements, by taking advantage of the characteristics of its specific problem domain: the simulation of crowds in indoor environments. Several algorithms are implemented to improve the efficiency of the management of a high number of agents in order to cope with the performance in the processing of their movements and their representation. At the same time, different models are supported to specify decision making of the agents in order to allow rich behaviours. Agents can represent different types of entities such as people, sensors and actuators. This is illustrated with a realistic case study of the evacuation of the building of our Faculty of Computer Science, where different types of human behaviours are modelled in this kind of situations.
