Tecnologías y cultura organizativa en los centros escolares. ¿La uberización de las relaciones laborales?
2020
El supuesto sobre el que se sustenta el presente trabajo, inspirado en las teorías clásicas de la organización, propone que el uso de dispositivos digitales en los centros escolares, especialmente de plataformas digitales, genera una cultura tecnológica entre el profesorado. El objetivo de este artículo es analizar las consecuencias de este fenómeno sobre la reestructuración del entramado organizativo del centro y del trabajo docente. Para ello, se parte de un estudio de casos múltiples en cuatro centros de Educación Primaria aplicando estrategias etnográficas, entre las que destacan las entrevistas realizadas al personal docente (profesorado, equipos directivos, titulares de centro). El an…
Quantifying the Potential Economic Benefits of Flexible Industrial Demand in the European Power System
2018
The envisaged decarbonization of the European power system introduces complex techno-economic challenges to its operation and development. Demand flexibility can significantly contribute in addressing these challenges and enable a cost-effective transition to the low-carbon future. Although extensive previous work has analyzed the impacts of residential and commercial demand flexibility, the respective potential of the industrial sector has not yet been thoroughly investigated despite its large size. This paper presents a novel, whole-system modeling framework to comprehensively quantify the potential economic benefits of flexible industrial demand (FID) for the European power system. This …
Education for Road Safety: What is the State of Affairs in Three Groups of Vulnerable Road Users in Spain?
2021
RSE (Road Safety Education) is well recognized as a reliable predictor of future safety and health outcomes. However, most countries have been slow to develop it, which has contributed to the sensitivity of the situation, as traffic accidents continue to be a major concern for community health. This paper aims to describe and compare key variables related to the RSE among three critical segments of the population, using the data provided by: 477 high school students, 843 university students and 476 older adults. Differential coverage rates were found. Perceived quality, aroused interest and attributed utility for RSE interventions were also compared among groups, finding substantial differe…
WebGIS Implementation for Dynamic Mapping and Visualization of Coastal Geospatial Data: A Case Study of BESS Project
2021
Within an E.U.-funded project, BESS (Pocket Beach Management and Remote Surveillance System), the notion of a geographic information system is an indispensable tool for managing the dynamics of georeferenced data and information for any form of territorial planning. This notion was further explored with the creation of a WebGIS portal that will allow local and regional stakeholders/authorities obtain an easy remote access tool to monitor the status of pocket beaches (PB) in the Maltese Archipelago and Sicily. In this paper, we provide a methodological approach for the implementation of a WebGIS necessary for very detailed dynamic mapping and visualization of geospatial coastal data
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 …
