    El saque de lateral es una de las formas de reinicio del juego o fases de conquista en un partido de rugby cuantitativa y cualitativamente importante. En este artículo se realizó un estudio descriptivo de los saques de lateral en un torneo internacional de alto nivel. En segundo lugar, se estudiaron las diferencias en esta fase de juego entre los distintos equipos participantes y, finalmente, determinamos las variables que inciden en la conquista de la pelota. A partir de un conjunto inicial de variables se desarrolló, mediante la validación con expertos, una herramienta para la observación de los factores clave. La muestra estuvo constituida por 358 saques de lateral del Torneo Seis Naciones de 2013 que se investigaron mediante análisis de vídeo. Los resultados han mostrado información relevante sobre las variables estudiadas (partido, equipo, casa/fuera, número del saque lateral, iluminación, lluvia, viento, tiempo, resultado, lado, zona, número de jugadores, estructura previa, estructura de salto, posición saltador, cambio de posición, movimiento, amague, ángulo, velocidad, tiempo vuelo, distancia, altura y conquista). Se encontraron diferencias entre los equipos en: el número de jugadores, el ángulo, el tiempo de vuelo y la altura. Por último, entre todas las variables investigadas, encontramos que hay una mayor probabilidad de conquista cuando el tiempo de vuelo dura entre 0,36 y 0,84 s, y la distancia es entre 5 y 10 m

    La gestación por sustitución contribuye a la transformación de las concepciones sociales de la filiación y los cambios en las estrategias reproductivas de las familias. En la presente contribución se relaciona la teoría de la atención reproductiva transfronteriza con las teorías posmodernas de la vida familiar, con el propósito de explorar qué temáticas, elementos y contenidos utilizan las agencias intermediarias de gestación por sustitución que tienen por destinatarios a las madres y padres de intención españoles. Se utiliza la metodología cualitativa y la técnica de análisis de contenido temático tras el registro de la información online recogida de las agencias. Los resultados evidencian el papel de estas agencias mediadoras en los procesos de gestación por sustitución en España, además de generar conocimiento en el área de las nuevas formas familiares constituidas mediante técnicas de reproducción asistida.Substitution pregnancy contributes to the transformation of social conceptions of filiation and changes in the reproductive strategies of families. This contribution relates the theory of cross-border reproductive care with post-modern theories of family life in order to explore which themes, elements and contents are used by intermediary surrogate pregnancy agencies which target Spanish mothers and fathers. The qualitative methodology and the technique of thematic content analysis after registration of the online information collected from the agencies is used. The results show the role of these intermediary agencies in the process of gestation by substitution in Spain, as well as generating knowledge in the area of new family forms constituted by assisted reproduction techniques

    [EN] This paper represents a final stage in the assessment of granular sub-ballast materials mixed with tyre-derived aggregate (TDA) without binder material. The objective is to evaluate such mixtures through a full-scale test under real traffic conditions. An experimental track with three 30-metre long sections was constructed: one section was built with conventional sub-ballast; and the other two sections were built with mixtures containing increasing rubber content. This track was then monitored using accelerometers. The results show a clear reduction in the acceleration peaks as rubber content increases. Moreover, the excited frequency bandwidth tends to become narrower and shifts to lower frequencies.The works presented in this paper are part of a research project (Project COMPOVIA) funded by the Spanish CDTI (Centro para el Desarrollo Tecnologico Industrial) and the CTA (Corporacion TecnolOgica de Andalucia). The authors also wish to thank ADIF for their collaboration during the measurements carried out in its facilities.Martínez Fernández, P.; Hidalgo Signes, C.; Villalba Sanchis, I.; Pérez Mira, D.; Insa Franco, R.

    This work is the result of an international research effort to determine the main impacts of the COVID-19 pandemic on marine recreational fishing. Changes were assessed on (1) access to fishing, derived from lockdowns and other mobility restrictions; (2) ecosystems, because of alterations in fishing intensity and human presence; (3) the blue economy, derived from alterations in the investments and expenses of the fishers; and (4) society, in relation to variations in fishers’ health and well-being. For this, a consultation with experts from 16 countries was carried out, as well as an international online survey aimed at recreational fishers, that included specific questions designed to capture fishers’ heterogeneity in relation to behavior, skills and know-how, and vital involvement. Fishers’ participation in the online survey (5,998 recreational fishers in 15 countries) was promoted through a marketing campaign. The sensitivity of the fishers’ clustering procedure, based on the captured heterogeneity, was evaluated by SIMPER analysis and by generalized linear models. Results from the expert consultation highlighted a worldwide reduction in marine recreational fishing activity. Lower human-driven pressures are expected to generate some benefits for marine ecosystems. However, experts also identified high negative impacts on the blue economy, as well as on fisher health and well-being because of the loss of recreational fishing opportunities. Most (98%) of the fishers who participated in the online survey were identified as advanced, showing a much higher degree of commitment to recreational fishing than basic fishers (2%). Advanced fishers were, in general, more pessimistic about the impacts of COVID-19, reporting higher reductions in physical activity and fish consumption, as well as poorer quality of night rest, foul mood, and raised more concerns about their health status. Controlled and safe access to marine recreational fisheries during pandemics would provide benefits to the health and well-being of people and reduce negative socioeconomic impacts, especially for vulnerable social groups.Versión del edito

    Fostering English-taught higher education programs in a Spanish university: the "TechEnglish" innovative project

    Get PDF
    In recent years, coinciding with adjustments to the Bologna process, many European universities have attempted to improve their international profile by increasing course offerings in English. According to the Institute of International Education (IIE), Spain has notably increased its English-taught higher education programs, ranking fifth in the list of European countries by number of English-taught Master's programs in 2013. This article presents the goals and preliminary results of an on-going innovative education project (TechEnglish) that aims to promote course offerings in English at the Technical University of Madrid (Universidad Politécnica de Madrid, UPM). The UPM is the oldest and largest of all Technical Universities in Spain. It offers graduate and postgraduate programs that cover all the engineering disciplines as well as architecture. Currently, the UPM has no specific bilingual/multilingual program to promote teaching in English, although there is an Educational Model Whitepaper (with a focus on undergraduate degrees) that promotes the development of activities like an International Semester or a unique shared curriculum. The TechEnglish project is an attempt to foster courses taught in English at 7 UPM Technical Schools, including students and 80 faculty members. Four tasks were identified: (1) to design a university wide framework to increase course offerings, (2) to identify administrative difficulties, (3) to increase visibility of courses offered, and (4) to disseminate the results of the project. First, to design a program we analyzed existing programs at other Spanish universities, and other projects and efforts already under way at the UPM. A total of 13 plans were analyzed and classified according to their relation with students (learning), professors (teaching), administration, course offerings, other actors/institutions within the university (e.g., language departments), funds and projects, dissemination activities, mobility plans and quality control. Second, to begin to identify administrative and organizational difficulties in the implementation of teaching in English, we first estimated the current and potential course offerings at the undergraduate level at the UPM using a survey (student, teacher and administrative demand, level of English and willingness to work in English). Third, to make the course offerings more attractive for both Spanish and international students we examined the way the most prestigious universities in Spain and in Europe try to improve the visibility of their academic offerings in English. Finally, to disseminate the results of the project we created a web page and a workspace on the Moodle education platform and prepared conferences and workshops within the UPM. Preliminary results show that increasing course offerings in English is an important step to promote the internationalization of the University. The main difficulties identified at the UPM were related to how to acknowledge/certify the departments, teachers or students involved in English courses, how students should register for the courses, how departments should split and schedule the courses (Spanish and English), and the lack of qualified personnel. A concerted effort could be made to increase the visibility of English-taught programs offered on-line

    Juxtaposing BTE and ATE – on the role of the European insurance industry in funding civil litigation

    Get PDF
    One of the ways in which legal services are financed, and indeed shaped, is through private insurance arrangement. Two contrasting types of legal expenses insurance contracts (LEI) seem to dominate in Europe: before the event (BTE) and after the event (ATE) legal expenses insurance. Notwithstanding institutional differences between different legal systems, BTE and ATE insurance arrangements may be instrumental if government policy is geared towards strengthening a market-oriented system of financing access to justice for individuals and business. At the same time, emphasizing the role of a private industry as a keeper of the gates to justice raises issues of accountability and transparency, not readily reconcilable with demands of competition. Moreover, multiple actors (clients, lawyers, courts, insurers) are involved, causing behavioural dynamics which are not easily predicted or influenced. Against this background, this paper looks into BTE and ATE arrangements by analysing the particularities of BTE and ATE arrangements currently available in some European jurisdictions and by painting a picture of their respective markets and legal contexts. This allows for some reflection on the performance of BTE and ATE providers as both financiers and keepers. Two issues emerge from the analysis that are worthy of some further reflection. Firstly, there is the problematic long-term sustainability of some ATE products. Secondly, the challenges faced by policymakers that would like to nudge consumers into voluntarily taking out BTE LEI

    Search for stop and higgsino production using diphoton Higgs boson decays

    Results are presented of a search for a "natural" supersymmetry scenario with gauge mediated symmetry breaking. It is assumed that only the supersymmetric partners of the top-quark (stop) and the Higgs boson (higgsino) are accessible. Events are examined in which there are two photons forming a Higgs boson candidate, and at least two b-quark jets. In 19.7 inverse femtobarns of proton-proton collision data at sqrt(s) = 8 TeV, recorded in the CMS experiment, no evidence of a signal is found and lower limits at the 95% confidence level are set, excluding the stop mass below 360 to 410 GeV, depending on the higgsino mass
