Manual de bones pràctiques per a la gestió de curses i marxes solidàries
No full textAquest manual de bones pràctiques és la culminació d’un projecte de recerca que pretén aprofundir en el coneixement de les curses i marxes solidàries en el nostre territori, pel que fa als seus trets característics, al perfil dels participants i a la gestió de la solidaritat. El projecte sorgeix arran de la percepció de l’existència de gran diversitat de formes de gestionar la solidaritat en curses esportives, de vegades sense mecanismes prou sòlids de rendició de comptes, la qual cosa pot condicionar els llindars de transparència de l’esdeveniment. Aquest document no és, però, un protocol ni pretén tenir un caràcter normatiu. Lluny d’això, l’objectiu és facilitar a les entitats organitzadores de curses i marxes solidàries un seguit d’orientacions per tal de desenvolupar la vessant solidària d’aquests esdeveniments i, alhora, establir pautes per tal d’afavorir la transparència i la rendició de comptesinfo:eu-repo/semantics/acceptedVersio
Privacy and e-learning: a pending task
No full textMost educational software programs use and gather personal information and metadata from students. Additionally, most of the educational software programs are no longer operated by the learning institutions but are run by third-party agencies. This means that in the decade since 2020, information about students is stored and handled outside premises and control of learning institutions. The personal information about students and their activity while they interact with learning management systems and online learning tools is increasingly in custody of cloud computing platforms, software-as-a-service providers, and learning tool vendors. There is an increasing will to use all the data and metadata from the activity of the students for research, to develop education management strategies, pedagogy approaches, and develop behavior control tools or learning tools informed by behavior analysis from learning analytics. Many times, these studies lack the ethical and moral perspective. In addition, there is an increasing number of cases in which this information has leaked or has been used in a shady way. Additionally, this information will be around for a long time, tied to the future digital profiles of the students whose data has been leaked. This paper hypothesizes that there has been an ongoing process of technological evolution that leads to a loss of control over personal information, which makes it even more difficult to protect user confidentiality and ensuring privacy, that data surveillance has entered the world of education, and that the current legal frameworks are not enough to really protect the student’s personal information. The paper analyzes how this situation came to pass, and why this is wrong. We conclude with some proposals to address it from its different root dimensions: technical, cultural, legal, and organizational.info:eu-repo/semantics/publishedVersio
Finite element hybrid and direct computational aeroacoustics at low Mach numbers in slow time-dependent domains
No full textIn this work, we address the finite element computation of flow noise in the presence of arbitrarily slowly moving rigid bodies at low Mach numbers, by means of hybrid and direct computational aeroacoustics (CAA) strategies. As regards the former, the problem could be dealt with by means of the Ffowcs Williams–Hawkings acoustic analogy. That reduces to Curle’s analogy for a static body, which is analogous to a problem of diffraction of sound waves generated by flow eddies in the vicinity of the body. Acoustic analogies in CAA first demand computing the flow motion to extract an acoustic source term from it and then use the latter to calculate the acoustic pressure field. However, in the case of low Mach number flows, the Ffowcs Williams–Hawkings and Curle analogies present a problem as they require knowing the total pressure distribution on the body’s boundary (i.e. the aerodynamic pressure plus the acoustic one). As incompressible computational fluid dynamics (CFD) simulations are usually performed to determine the flow motion, the acoustic pressure distribution on the body surface is unavoidably missing, which can yield acoustic analogies inaccurate. In a recent work, it was proposed to tackle that problem for static and rigid surfaces, by keeping the incompressible CFD and then splitting the acoustic pressure into direct and diffracted components. Two separate wave equations were solved for them, in the framework of the finite element method (FEM). In this article, we extend that work to compute the aerodynamic sound generated by a flow interacting with a slowly moving rigid body. The incompressible Navier–Stokes equations are first solved in an arbitrary Lagrangian–Eulerian (ALE) frame of reference to obtain the acoustic source term. Advantage is then taken from the same computational run to separately solve two acoustic ALE wave equations in mixed form for the incident and diffracted acoustic pressure components. For validation of the total acoustic pressure field, an ALE formulation of a direct CAA approach consisting of a unified solver for a compressible isentropic flow in primitive variables is considered. The performance of the exposed methods is illustrated for the aeroacoustics of flow past a slowly oscillating two-dimensional NACA airfoil and for flow exiting a duct with a moving teeth-shaped obstacle at its termination.info:eu-repo/semantics/acceptedVersio

Cataluña. Un sistema deportivo en revisión
No full textDurante las últimas décadas, el deporte se ha convertido en un tema de gran interés para las Ciencias Sociales. A ello han contribuido su creciente relevancia socioeconómica y sus contrastados beneficios para la salud, pero también la apuesta cada vez más firme de las Administraciones Públicas por aumentar la práctica deportiva de la población.
Este libro se centra en la situación del deporte en España, pero a diferencia de otros trabajos, lo hace desde una perspectiva autonómica. Este prisma resulta ineludible si se tiene en cuenta que la aprobación de la Constitución en 1978 convirtió la promoción del deporte en una competencia de las Comunidades Autónomas (art. 148.19).
De acuerdo con ese enfoque, los capítulos que componen este libro proporcionan una radiografía del sistema deportivo de cada una de las 17 Comunidades Autónomas y tratan de responder a las siguientes preguntas: ¿cuáles son los aspectos más característicos de la evolución histórica del deporte en cada territorio?, ¿cómo están organizados y articulados formalmente sus sistemas deportivos?, ¿cuáles son sus dimensiones económicas?, ¿en qué aspectos se han centrado las políticas deportivas de los últimos años?, ¿qué pautas caracterizan la participación y la cultura deportiva de cada Comunidad Autónoma? y ¿cuáles son sus principales retos de futuro?info:eu-repo/semantics/publishedVersio

EcoSentinel: Towards a techno natural internet of things approach for large scale sustainable remote monitoring of soil and wilderness
No full textMonitoring soil and wilderness is essential for environmental sustainability, biodiversity conservation, and climate resilience. Healthy soils support carbon sequestration, regulate water cycles, and sustain ecosystems, while wild environments play a crucial role in preserving biodiversity and mitigating climate change. Current approaches to continuous monitoring of land degradation, soil quality, or ecosystem shifts consist of manual observation and measurement of the environmental conditions, which are limited
to the availability of human resources and the dimensions of the area to be measured. Also, current automatic solutions aimed to augment human capabilities—ranging from satellite observation to in-field wireless sensor networks—stem from challenges in terms of power supply, data transmission, sensor durability, scalability, and integration with natural systems. The purpose of this paper is to propose EcoSentinel: a Techno-Natural Internet of Things (IoT) approach specifically designed for large-scale, sustainable remote monitoring of soil and wilderness. By leveraging the biological processes and resilience of plants, EcoSentinel aims to enable them to function as self-sustained digital nodes within a wireless network. This is achieved through energy harvesting from plant microbial fuel cells and electromagnetic signal propagation through the plants’ leaves, allowing plants to autonomously sense and transmit environmental data. This plantbased IoT system introduces a new paradigm of plant-plant cybernetic interaction, digitally transforming natural ecosystems. This paper presents the theoretical
foundations, system architecture, and potential applications of EcoSentinel, paving the way for a new era of bio-integrated environmental monitoring IoT technologies.info:eu-repo/semantics/acceptedVersio
