The Relationship between Motivational Climate and Personal Treatment Satisfaction among Young Soccer Players in Norway: The Moderating Role of Suppor…
2020
Motivational climate and coach-behaviour seem important to understand sport involvement and participation. However, less is known about the potential interaction between these facets, and how it relates to athlete satisfaction. This study&rsquo
The digital divide in the world of education at the time of Covid-19
2021
Education in the digital age uses new intelligent technologies as enabling and daily tools at the service of learning. Education has always been a challenge and today it is even more so since, given the many difficulties of the moment, to support the school in the time of Covid-19 it is necessary to implement rapid and timely changes that require, in addition to high investments, also new ways of sharing knowledge. Only by acting in this direction is it possible to make a virtue of necessity and transform the many critical issues, due to the pandemic causes, into strategic opportunities. The spread of Covid-19 has forced 80% of students around the world to not go to school and stay at home,…
Emerging Trends, Issues, and Challenges in Big Data and Its Implementation toward Future Smart Cities
2017
The articles in this special section focus on Big Data as it impacts future smart cities. The world is experiencing a period of extreme urbanization. Moreover, this process will continue, and the global urban population is expected to double by 2050. Smart city has been proposed to improve the efficiency of services and meet residents’ needs for better quality of life. Essentially, smart city integrates the Internet of Things and emerging communication technologies such as fifth generation (5G) solutions to manage the citys’ assets, including transportation systems, hospitals, water supply networks, waste management, and so on. Therefore, smart city is driving innovation and new technologie…
Use of ICT to support epidemiological surveillance on a community of university students during SARS-CoV-2 phase 3 pandemic
2021
Populations documenting to date low incidence rates of SARS-CoV-2 infection are immunologically susceptible and at high exposure risk of new COVID-19 outbreaks during phase 3 of the pandemic. Following the experience documented by other countries with regard to the use of Information Communication Technology (ICT) to counteract the current pandemic, Italy has implemented a contact tracing system based on a mobile application. In this work, we describe the proposal of a complementary ICT-based prototypal model of COVID-19 prevention and surveillance system, involving the university students as sentinels acting both in the academic community and the general population.
The impact of noise on the population of an urban centre in Valencia (Spain)
1997
Acoustic contamination in residential areas is a generalized problem. This paper reports the results of a survey trying to evaluate this contamination in the historical center of Valencia and about its effects upon that district's residents. A total of 700 residents in 11 different neighbourhoods of the city of Valencia were interviewed; at the same time environmental noise was determined at 225 different points within the area of study. In the historical center of Valencia, there exists an important problem of environmental noise and the daily levels clearly exceed the recommended limits.
Towards a Framework for Cross-Sector Collaboration: Implementing a Resilience Information Portal
2017
Municipalities play an integral part in the strive for resilient societies. A resilient municipality is not only prepared for short-term shocks such as natural disasters but also more successful in mastering long-term stresses such as profound in-creases or decreases of population. Backed by a large-scale research project we have developed a Resilience Information Portal (RIP). It serves as an artefact to support cross-sector collaboration within a municipality. The core challenges in implementing such a portal reside not in the technological work, though. Rather, it needs to be implemented in the communication and IT strategy of a municipality and be tailored to the processes. In this arti…
Smartphone data analysis for human activity recognition
2017
In recent years, the percentage of the population owning a smartphone has increased significantly. These devices provide the user with more and more functions, so that anyone is encouraged to carry one during the day, implicitly producing that can be analysed to infer knowledge of the userâs context. In this work we present a novel framework for Human Activity Recognition (HAR) using smartphone data captured by means of embedded triaxial accelerometer and gyroscope sensors. Some statistics over the captured sensor data are computed to model each activity, then real-time classification is performed by means of an efficient supervised learning technique. The system we propose also adopts a …
A distributed visualization system for crowd simulations1
2011
The visualization system of large-scale crowd simulations should scale up with both the number of visuals views of the virtual world and the number of agents displayed in each visual. Otherwise, we could have large scale crowd simulations where only a small percentage of the population is displayed. Several approaches have been proposed in order to efficiently render crowds of animated characters. However, these approaches either render crowds animated with simple behaviors or they can only support a few hundreds of user-driven entities. In this paper, we propose a distributed visualization system for large crowds of autonomous agents that allows the visualization of crowds animated with co…
Design of virtual environments for the treatment of agoraphobia: Inclusion of culturally relevant elements for the population of the Dominican Republ…
2020
Abstract Virtual Reality is a powerful tool for the treatment of agoraphobia. However, how effective is the use of these scenarios when they do not resemble the sociocultural context? Literature suggests that the inclusion of culturally relevant elements increases the ecological validity and transferability of learning since it reduces the gap between the virtual and real context. Unfortunately, in Latin America, the development of virtual environments is incipient, and the use of generic virtual environments is commonplace. The objective of this study was to develop virtual environments that include elements that are culturally relevant to the population of the Dominican Republic. Three hu…
Virtual Reality in Education : Focus on the Role of Emotions and Physiological Reactivity
2019
Cognitive and emotional dimensions are often linked to each other in learning experiences. Moreover, emotions and engagement can lead to better outcomes at the cognitive level. Previous research has indicated that virtual reality (VR) provides a feeling of presence and immersion, which can trigger emotionally engaging learning situations. In this study, we explore the opportunities and challenges related to the use of VR in an educational context. The focus of this article is threefold: First, we explore interdisciplinary research literature related to the use of VR for educational purposes. Second, we introduce our VR pilot study in teacher education, applying three different kinds of VR a…
