Formulations and valid inequalities for the capacitated dispersion problem
2023
This work focuses on the capacitated dispersion problem for which we study several mathematical formulations in different spaces using variables associated with nodes, edges, and costs. The relationships among the presented formulations are investigated by comparing the projections of the feasible sets of the LP relaxations onto the subspace of natural variables. These formulations are then strengthened with families of valid inequalities and variable-fixing procedures. The separation problems associated with the valid inequalities that are exponential in number are shown to be polynomially solvable by reducing them to longest path problems in acyclic graphs. The dual bounds obtained from s…
Attitudes and perceptions of faculty members in the process adopting innovation: The OpenCourseWare initiative at the University of Valencia, Spain
2014
The OpenCourseWare project, an open learning resource repository, was established at the University of Valencia between 2008 and2009. It initially consisted of only 10 subjects, none of which was in the field of Health Sciences. The objective of this research was toinvestigate the attitudes and perceptions of faculty members in the field of Health Sciences with regard to the project to identify strategies to increase its use and expand its coverage. We applied Rogers’ innovation-diffusion theory along with a qualitative approach using theoretical sampling, semi-structured interviews and open coding. The results indicate the existence of two categories of faculty members. In the first group,…
Estimación del impacto económico de los museos a través de las nuevas tecnologías de la información: el caso del museo Ene.Térmica
2015
It is increasingly necessary to emphasize the potential of culture as an engine for economic development and its ability to generateincome and create jobs. For this reason, this paper evaluates the economic impact of the Ene.térmica museum in the territory in which it is located, Ponferrada (Castilla y León Community, Spain). In order to achieve this aim, the estimation of the different types of effects needed to determine the impact of economic of the activities linked to the existence of Ene.Térmica is calculated by using the tool Impactrimonio, a web-based application that applies the Input-Output Tables methodology. The results show that due to both activities of the museum and demand f…
Robots as intelligent assistants to face COVID-19 pandemic
2020
AbstractMotivationThe epidemic at the beginning of this year, due to a new virus in the coronavirus family, is causing many deaths and is bringing the world economy to its knees. Moreover, situations of this kind are historically cyclical. The symptoms and treatment of infected patients are, for better or worse even for new viruses, always the same: more or less severe flu symptoms, isolation and full hygiene. By now man has learned how to manage epidemic situations, but deaths and negative effects continue to occur. What about technology? What effect has the actual technological progress we have achieved? In this review, we wonder about the role of robotics in the fight against COVID. It p…
Trajectory of Affordances: Insights from a case of telemedicine in Nepal
2017
Although Affordance Theory has become increasingly influential in the Information Systems (IS) literature, the exact process through which the affordances of IT are actualised is less studied. In t ...
RFID Technology for IoT-Based Personal Healthcare in Smart Spaces
2014
The current evolution of the traditional medical model toward the participatory medicine can be boosted by the Internet of Things (IoT) paradigm involving sensors (environmental, wearable, and implanted) spread inside domestic environments with the purpose to monitor the user’s health and activate remote assistance. RF identification (RFID) technology is now mature to provide part of the IoT physical layer for the personal healthcare in smart environments through low-cost, energy-autonomous, and disposable sensors. It is here presented a survey on the state-of-the-art of RFID for application to bodycentric systems and for gathering information (temperature, humidity, and other gases) about …
The EU-project United4Health: User-centred design of an information system for a Norwegian telemedicine service.
2015
Introduction Organizational changes of health care services in Norway brought to light a need for new clinical pathways. This study presents the design and evaluation of an information system for a new telemedicine service for chronic obstructive pulmonary disease patients after hospital discharge. Methods A user-centred design approach was employed composed of a workshop with end-users, two user tests and a field trial. For data collection, qualitative methods such as observations, semi-structured interviews and a questionnaire were used. Results User workshop’s outcome informed the implementation of the system initial prototype, evaluated by end-users in a usability laboratory. Several us…

2018
Information and Communication Technology (ICT) can play a crucial role in meeting multifaceted developmental challenges such as providing access to quality health care in developing countries. Init ...
Dirección de tesis doctorales como reflejo de la Biblioteconomía y Documentación académica española: actores y temas
2020
Doctoral dissertations enable the transfer of research skills and capacities to future generations and the consolidation of lines of research in a given area of knowledge. The field of Library and Information Science in public universities in Spain is characterized by the supervision of doctoral theses by academics in the area. We identified active professors during the 2019–2020 academic year, their date of appointment as civil servants within the public university system, the dissertations that they supervised, and their participation in papers published in scientific journals. The analysis included 644 theses. About a quarter (23%) of university faculty have never supervised a doctoral t…
Analysis and Comparison of Deep Learning Networks for Supporting Sentiment Mining in Text Corpora
2020
In this paper, we tackle the problem of the irony and sarcasm detection for the Italian language to contribute to the enrichment of the sentiment analysis field. We analyze and compare five deep-learning systems. Results show the high suitability of such systems to face the problem by achieving 93% of F1-Score in the best case. Furthermore, we briefly analyze the model architectures in order to choose the best compromise between performances and complexity.
