Aerosol Lidar Intercomparison in the Framework of SPALINET—The Spanish Lidar Network: Methodology and Results
2009
Abstract—A group of eight Spanish lidars was formed in order to extend the European Aerosol Research Lidar Network–Advanced Sustainable Observation System (EARLINET-ASOS)project. This study presents intercomparisons at the hardware and software levels. Results of the system intercomparisons are based on range-square-corrected signals in cases where the lidars viewed the same atmospheres. Comparisons were also made for aeros backscatter coefficients at 1064 nm (2 systems) and 532 nm (all systems), and for extinction coefficients at 532 nm (2 systems). In total, three field campaigns were carried out between 2006 and 2007. Comparisons were limited to the highest layer found before the free tr…
A tutorização das práticas escolares na educação física através do edublog: uma ferramenta para a comunicação e reflexão contínua e conjunta
2022
RESUMO: A Tecnologia de informação e comunicação (TIC) revolucionou o processo ensino-aprendizagem. O uso de blogs no campo educacional é uma realidade crescente que levou ao desenvolvimento de um gênero específico, o edublog. Dessa forma, as práticas escolares na Educação Física, também denominadas Practicum III, realizadas no último ano do Curso de Licenciatura de Professores do Ensino Básico em Espanha são um momento chave para o futuro professor desta especialidade. Por isso, o monitoramento contínuo e a comunicação direta e fluída entre os alunos e o tutor universitário favorecem uma tutoria de qualidade. O objetivo deste projeto de boas práticas e inovação consiste em projetar e imple…
International Standing Conference for the History of Education (ISCHE) Networks, internationalisation, and scientific communication
2022
The objective of this study is to map the international networks of research, circulation, and scientific communication in the history of education, at a global level. In order to do so, we analyse the activity of the International Standing Conference for the History of Education (ISCHE). The focus is placed on the following: the make-up and organisation of the community of education historians; the arenas set up to encourage collaboration, debate and consensus in research in the field; collaboration among researchers, and the influence of transnational perspectives; avenues of research and areas of focus; and the communication channels by which ideas and findings are published and exchange…
Redes de apoyo al emprendimiento femenino en territorios rurales
2020
Las condiciones del mercado de trabajo en las áreas rurales han convertido el autoempleo en una de las opciones recurrentes entre las mujeres que tratan de iniciar una actividad o consolidar su económica. Mediante técnicas cualitativas y a partir de un caso de estudio en un área LEADER española (Sierra del Segura, Albacete), este trabajo investiga las redes locales de apoyo al autoempleo femenino en zonas rurales, así como el impacto de la crisis económica sobre dicho sistema de apoyos. Los resultados más destacados señalan la importancia del asociacionismo empresarial femenino (redes formales) y los liderazgos locales (redes informales) como apoyos-fuerza al emprendimiento femenino rural. …
Culture of information and information exchange in a public hospital : a study based on the information orientation model and social network analysis
2022
The structures of hospitals have evolved to make them centre on patients and their pathologies, with care procedures that are both interprofessional and interorganisational. This has given rise to work environments made up of teams obliged to collaborate in their problem-solving, with an essential focus on proper collaborative information behaviour (CIB). The aim was to study this behaviour in a clinical service of a hospital in relation to two aspects: information culture (IC) and the exchange of information. This entailed designing a two-part descriptive study. The first step was to administer a survey based on the information orientation model to know more about the service’s IC. The sec…

Supporting scalable video transmission in MANETs through distributed admission control mechanisms
2009
Emerging multimedia applications over mobile devices are becoming very popular, especially over infrastructure wireless networks such as cellular and WLANs. However, providing this kind of services over infrastructureless networks like ad hoc networks presents many additional problems. One of these problems is how to share resources fairly among the users involved. In this article we propose a QoS framework supporting scalable video streaming in mobile ad hoc networks based on distributed admission control and video traffic awareness. Our framework promotes fairness between video flows in terms of resource consumption. It also guarantees a significant reduction of the idle times experienced…
Predominio de las cheapfakes en redes sociales. Complejidad técnica y funciones textuales de la desinformación desmentida en Argentina durante 2020
2022
Research on disinformation concentrates a growing interest in the design of deepfakes and the possible political, economic and social implications of their viral dissemination on social networks. However, as much or more worrying are the cheapfakes: the hoaxes created by the users themselves through the native features of their mobile devices, the rude manipulation of pre-existing files or the simple addition of text that alters the original meaning of the shared messages. The objective of this research is to analyze the degree of technological complexity of the disinformation that circulated in Argentina during 2020 throughout social networks, as well as the role that the text played in it…
Underwater Multirobot Cooperative Intervention MAC Protocol
2020
This work introduces a Medium Access Control (MAC) protocol designed to allow a group of underwater robots that share a wireless communication channel to effectively communicate with each other. The goal of the Underwater Multirobot Cooperative Intervention MAC (UMCI-MAC) protocol presented in this work is to minimize the end to end delay and the jitter. The access to the medium in UMCI-MAC follows a Time Division Multiple Access (TDMA) strategy which is arbitrated by a master, which also has the capability to prioritize the transmission of some nodes over the rest of the network. Two experiments have been carried out with a team of four Autonomous Underwater Vehicles (AUV) in order to comp…
