Relational justice: mediation and ODR through the World Wide Web

ODR means "Online Dispute Resolution". Dialogue, negotiation and mediation are coming back as sources of contemporary law. We introduce in this paper two concepts and two related projects. We define the concepts of "relational law" and "relational justice". And, at the same time, we describe how to put them in place from a social and technological point of view. Therefore, we introduce two concrete applications: (i) the Catalan White Book on Mediation, a large project to assemble the required social and legal knowledge to draft a general statute on mediation (Catalan Government); (ii) the Ontomedia Project, a semantically-driven platform allowing end-users to negotiate and mediate their conflicts in several domains (family, commerce, environment, health care, administration…). The paper describes the state of the art of ODR services, and proposes some strategies for legal electronic institutions. A middle-out theoretical approach and a mediation core-ontology are briefly described. We situate these two projects within the next generation of Semantic Web services, and the so-called Web 2.0 and Web 3.0 developments

ODR, ontologies, and web 2.0

Online communities and institutions create new spaces for interaction, but also open new avenues for the emergence of grievances, claims, and disputes. Consequently, online dispute resolution (ODR) procedures are core to these new online worlds. But can ODR mechanisms provide sufficient levels of reputation, trust, and enforceability for it to become mainstream? This contribution introduces the new approaches to ODR and provides a description of the design and structure of Ontomedia, a web-based platform to facilitate online mediation in different domain

The last five years of Big Data Research in Economics, Econometrics and Finance: Identification and conceptual analysis

Today, the Big Data term has a multidimensional approach where five main characteristics stand out: volume, velocity, veracity, value and variety. It has changed from being an emerging theme to a growing research area. In this respect, this study analyses the literature on Big Data in the Economics, Econometrics and Finance field. To do that, 1.034 publications from 2015 to 2019 were evaluated using SciMAT as a bibliometric and network analysis software. SciMAT offers a complete approach of the field and evaluates the most cited and productive authors, countries and subject areas related to Big Data. Lastly, a science map is performed to understand the intellectual structure and the main research lines (themes)

The ontomedia project : ODR, relational justice, multimedia

More than ever, the Web is a space of social interaction. Recent trends reveal that Internet users spend more time interacting within online communities than in checking and replying to e-mail. Online communities and institutions create new spaces for interaction, but also open new avenues for the emergence of grievances, claims, and disputes. Consequently, online dispute resolution (ODR) procedures are core to these new online worlds. But can ODR mechanisms provide sufficient levels of reputation, trust ,and enforceability so as to become mainstream? This contribution introduces the new approaches to ODR with an emphasis on the Ontomedia Project, which is currently developing a web-based platform to facilitate online mediation in different domains

Global trends in coronavirus research at the time of Covid-19: A general bibliometric approach and content analysis using SciMAT

Covid-19 represents the greatest challenge facing mankind today. In December 2019, several cases of pneumonia of unknown etiology were reported from China. This coronavirus infection subsequently identified as Covid-19 aroused worldwide concern. As a result, the scientific community has focused attention on Covid-19, as revealed by recent research reported in literature based on a holistic approach. In this regard, this study conducts a bibliometric analysis of coronavirus research in the literature with an emphasis on Covid-19 disease, using as a reference the publications in the Web of Science Core Collection from 1970 to 2020. This research analyzes 12,571 publications from 1970 to (April 18) 2020 by applying advanced bibliometric techniques in SciMAT bibliometric analysis software. The current research therefore provides a complete conceptual analysis of the main coronavirus types and strains in the literature by quantifying the main bibliometric performance indicators, identifying the main authors, organizations, countries, sources, and research areas, and evaluating the development of this field. Furthermore, a science map is constructed to understand the corresponding intellectual structure and main research lines (themes). SciMAT thereby offers a complete approach to the field and evaluates the main performance indicators related to coronavirus, with a focus on Covid-19. Finally, this research serves as a framework to strengthen existing research lines and develop new ones, establishing synergistic relationships that were not visible without the maps generated herein

Switchable fiber optic laser system for high and low-strain fiber optic sensors remote multiplexing

In this paper, a 50 Km remote and switchable fiber optic sensing system based on an erbium doped fiber ring laser is proposed. The system allows the integration of different interrogation methods based on the detection of wavelength or amplitude variations of the laser. This integration is carried out by sequentially activating different ring cavities by using an optical switch. With this scheme, the maximum gain zone of the erbium doped fiber amplifier can be used to increase the distance of the sensor system. A bending intensity sensor and a FBG based strain sensor were successfully tested for high and low-strain measurements respectively. This system includes all the active elements inside the monitoring station, enabling the remote monitoring of the sensors.The authors are grateful to the Spanish government project TEC2010-20224-C02, to the Spanish Ministry of Education and Culture, and to the grant AP2009-1403

Engineering aspheric liquid crystal lenses by using the transmission electrode technique

The transmission electrode technique has been recently proposed as a versatile method to obtain various types of liquid-crystal (LC) lenses. In this work, an equivalent electric circuit and new analytical expressions based on this technique are developed. In addition, novel electrode shapes are proposed in order to generate different phase profiles. The analytical expressions depend on manufacturing parameters that have been optimized by using the least squares method. Thanks to the proposed design equations and the associated optimization, the feasibility of engineering any kind of aspheric LC lenses is demonstrated, which is key to obtain aberration-free lenses. The results are compared to numerical simulations validating the proposed equations. This novel technique, in combination with the proposed design equations, opens a new path for the design and fabrication of LC lenses and even other types of adaptive-focus lenses based on voltage control.This work was supported by Comunidad de Madrid and FEDER Program (S2018/NMT-4326), the Ministerio de Economía y Competitividad of Spain (TEC2016-77242-C3-1-R and TEC2016-76021-C2-2-R), the FEDER/Ministerio de Ciencia, Innovación y Universidades and Agencia Estatal de Investigación (RTC2017-6321-1, PID2019-107270RB-C21 and PID2019-109072RB-C31)

Linking the semantic web to ODR: the Ontomedia project

Despite the conceptual vagueness of definitions, both Web 2.0 and Web 3.0 are opening up for ever-growing communities of users new forms of online interaction and customization of information. In this article we explore some of the critical features of Web 2.0 and 3.0 developments applied to different conflict domains, and then present some of the basic components of the Ontomedia platform. The Ontomedia project aims to provide mediation experts and users with a semantically enriched mediation platform where they are able to interact, mediate, and retrieve useful information on related cases in an effective and friendly way

Single longitudinal mode lasers by using artificially controlled backscattering erbium doped fibers

In this work, we propose and experimentally demonstrate a new distributed short linear cavity fiber laser. At one of the cavity ends, fabricated by a commercial femtosecond fiber laser chirped pulse amplifier, an artificially controlled backscattering erbium doped fiber section has been connected. This distributed reflector acts also as a saturable absorber, leading to the generation of tunable and switchable single longitudinal-mode laser emissions. The distributed reflector consists of 9 micro-drilled sections of about 1cm each one and randomly spread throughout 2 meters of highly doped erbium fiber. The total length of the fiber laser is 9.5 m and the laser shows a single mode behavior at all the emitted wavelengths. Using this new kind of reflecting saturable absorber, single and multiple single-mode emissions can be obtained. The achieved laser presents a pump threshold as low as 45 mW and shows up to 8 different single-mode emission lines with an optical signal to noise ratio of 45dB.This work was supported in part by the MINECO/AEI (Ministerio de Economía y Competitividad/Agencia Estatal de Investigación), Spain, under Grant TEC2016-76021-C2-1-R, Grant TEC2016-76021-C2-2-R, and Grant PID2019-107270RB; in part by the Ministerio de Educación, Cultura y Deporte of Spain under Grant FPU2018/02797, and in part by the Projects for Young Researches UPNA 2019 (Universidad Publica de Navarra) and FEDER Funds (European Regional Development Fund)
