    Energy harvesting from vehicular traffic over speed bumps: A review

    Get PDF
    Energy used by vehicles to slow down in areas of limited speed is wasted. A traffic energy-harvesting device (TEHD) is capable of harvesting vehicle energy when passing over a speed bump. This paper presents a classification of the different technologies used in the existing TEHDs. Moreover, an estimation of the energy that could be harvested with the different technologies and their cost has been elaborated. The energy recovered with these devices could be used for marking and lighting of roads in urban areas, making transportation infrastructures more sustainable and environmentally friendly

    Casting Stones with Intent: Transnational Interventions towards Ethical and Reparative Memorialisation

    Get PDF
    In the summer of 2020, on the wave of the Black Lives Matter Movement, statues and public monuments became focal points of political struggle, perceived by many as symbolic reminders of pervading western imperial legacies. Yet, the debate over public memorialisation is far from new. Starting from the 2020 BLM protests in Britain and going back to previous campaigns, this article contextualises the toppling, effacing and removal of well-known statues of colonial agents in Britain, Australia and Aotearoa New Zealand and examines artistic interventions which appropriate, challenge and shatter static historical interpretations of imperial figures and events. Our contention is that these interventions constitute diverse forms of performative and re-storied resistance reflecting transnational demands for redress and reparation.This publication derives from the Teaching Innovation Project: “CultivARTE: Elaboración colaborativa de materiales didácticos multimedia en el aula de literatura y cultura” financed by IRIE, UIB.

    Desórdenes informativos: sobreexpuestos e infrainformados en la era de la posverdad

    Information disorders (misinformation, fakes news, alternative facts, post-truth, deepfakes, etc.) are intentional productions whose strategy is focused on the fabrication of doubt and false controversies in order to achieve economic or ideological benefits. Information disorders are all interrelated and depend, in a necessary way, on post-Internet technologies which have modified the very nature of collective interpersonal communication. Information disorders have their origin and basis in different causes that have facilitated their development, scope and unprecedented current impact as: a) the war on science from the corporate sphere, b) the crisis of the post Internet national and local media, c) the development of technological platforms that have socialized the ability to publish and distribute content at low cost, d) the crisis of the experts with a consequent epistemic crisis, e) advances in psychology, that exploit the psychological bases of informative disorders through cognitive biases, and f) a significant change in the way of understanding and exercising power in the 21st century, such as the ability to establish the relations of definition of reality itself (Beck, 2017). This supposes a true will of authority on the reality and, in the practice, a will of ideological supremacy and a serious risk for the liberal democracies

    Making the invisible visible: visualizing the network structure of Twitter relationships using Social Network Analysis

    Get PDF
    We live in a dense social network of interactions that connect us to people, information, events and places facilitating or constraining the flow of information, ideas, perceptions, etc., into an instant and massive network communication system. We create cognitive artefacts that integrate data visualization and cognitive processes in order to increase our ability to understand the complexity of the external world, made even more complex with the Internet and rise of social media. In this paper, we combine Twitter , as a type of fieldwork site, and Social Networks Analysis (SNA), as both an analytic framework and set of methods, to capture, analyze, and visualize empirical data, both statically (figure representing point in time) and dynamically (video reflecting longitudinal data). We present Flocker, a tool designed for real-time visualization and representation of network activity using Twitter as an illustrative case

    Conectar a los desconectados: Trabajo Social y análisis de redes sociales. Una aproximación metodológica para identificar líderes informales en red

    Get PDF
    Social network theory and analysis (SNA) offers a useful conceptual framework and a robust set of methods for understanding, analysing, and representing the pattern of social interactions that surround individuals forming an overall network of ties. SNA provides both insights and applications regarding relational structures that may be consequential for individual and collective agency. Despite the fact that both SNA and social work focus on relationships and behaviour, and that each discipline could substantively inform the other, there remains a significant lack of intersection between the two disciplines. In response to this gap, SNA applied to social work can provide additional ways to both diagnose and intervene behaviourally through the following approaches: a) by identifying key players in promoting the dissemination of behavioral changes in networks; b) by segmenting and identifying groups, cliques and communities; c) by supporting behavioural change through social ties surrounding the individual; and d) by aligning and applying specific interventions that draw on mutually interactive processes in terms of individual influences on networks, as well as network influences on individuals. SNA provides social work with an additional lens and set of tools based on the constellation of interactions surrounding individuals, families, groups or communities that supports understanding, diagnosis, and intervention.La Teoría y Análisis de Redes Sociales (SNA) ofrece un conjunto de métodos de análisis de las interacciones sociales de los seres humanos, que permiten de forma específica investigar las estructuras relacionales y la representación de éstas como redes. SNA proporciona tanto acceso a nuevo conocimiento como la representación de las estructuras relacionales y como éstas pueden ser consecuencia de la acción individual y colectiva. A pesar de que tanto el SNA como el Trabajo Social tienen su foco en las relaciones y el comportamiento, de lo que ambas pueden beneficiarse, es significativa la falta de intersección entre ambas disciplinas. En respuesta a este déficit, el SNA puede ser aplicado al Trabajo Social desde los siguientes enfoques: a) la identificación de individuos claves a la hora de promover la difusión de cambios de comportamiento en redes; b) la segmentación e identificación de grupos, cliques y comunidades; c) el cambio de comportamientos a través de los miembros de la red y no del trabajador social como agente de cambio central; y d) que la intervención orientada al cambio de comportamientos puede ser bidireccional: individuos-red y red-individuos. El SNA aporta al Trabajo Social la base estructural-relacional para trabajar con individuos, grupos, familias o comunidades basados en patrones de interacción social, traduciendo los conceptos de las Ciencias Sociales y del Trabajo Social al servicio del diagnóstico y la intervención en red

    Infosociability: Monitoring and research on the web 2.0 for decision making

    Get PDF
    This methodology offers an approach to studying the information available within Web 2.0 Media and User-Generated Content (MUGC). The large-scale generation of online information is the result of collective social action based on information: infosociability. Competitive Intelligence (CI) aims to monitor and research a company’s web 2.0 environment for information relevant to its decision-making process. Facing the possibilities and limitations that today’s technology offers for processing the communication of meanings and abstract ideas in text format, a methodology derived from empirical research on web 2.0 is proposed. Monitoring and research are identified as the two key processes that generate insights aimed to facilitate decision-making. The relevance of each stage is illustrated with reference to the diverse methodological challenges encountered while extracting and analyzing large amounts of online information
