- Abstract
This perspective piece sets out to contribute to the academic and practitioner debates around energy transitions and democracy initiatives in the age of a climate crisis. For tackling present-day energy challenges in a democratic, equitable and just manner, critical social science and humanities research on meaning and materialities, new actors and narratives, values and democracy is indispensable. In doing so, we centralize our work around three fundamental axes: The Concept, reflecting on the energy itself and revitalizing its essence; The Political, embracing the value laden, political and gendered nature of energy, and recognizing citizens' initiatives as counter currents to centralized energy decision-making; and The People, anticipating the far right’s post-truth narratives that jeopardize planetary futures. We contend that “normative, political and embodied” research and praxis can serve for diversifying the energy transition debate as well as energizing bottom-up community led initiatives in order to democratize the energy playing field of recent times.

In the last decades, several studies have demonstrated and given a valuable insight about the existence of a global climate change. Even though the existence of a high regional heterogeneity about the level and temporality of climate change impacts, the trends of the potential future changes on the temperature and precipitation patterns are better known and consequently the potential impacts on the Biosphere and the Cryosphere. In this context, mountain regions have been identified as highly vulnerable areas to the effects of climate change and especially interesting areas for the detection and assessment of the potential changes and impacts. Moreover, in the last few decades, winter tourism, highly dependent on weather and snow availability, has become one of the main economic activities and source of local development in many mountain regions around the world. The Pyrenees, one of the most important winter tourism areas in Europe after the Alps, is a clear example of this pattern. The aim of the NIVO PYR project, an international research project in the framework of the Working Community of the Pyrenees (CTP), is to analyze the effects of the climate change on the winter tourism, and especially alpine ski tourism, in the Pyrenees. In order to achieve this objective the project intended to joint the current knowledge about the effects of climate change on temperatures, precipitations, snow cover and skiers behavior in the Pyrenees and develop for first time objective and accurate results for this area. To achieve this goal several methods have been used including, historical analysis of climatical series evolution, assessment of different future climate change scenarios for the Pyrenees, modeling future snowpack based on surface energy balance models and agent based modeling for coupling physical and socioeconomic parameters. One of the main results of this project was the identification of different ski resorts profiles depending on their vulnerability to climate change. Three different groups were identified. The first group includes the high vulnerable ski resorts, effected both by a mid and a high-climate change scenario. The second group, includes the low vulnerable ski resorts, affected by a high-climate change scenario but able to be viable with technical adaptation measures in a mid-climate change scenario. Finally, the group of resilient ski resorts includes the geographically and socioeconomically privileged compared to the rest of Pyrenean ski resorts. These ski resorts would be viable both in a mid and a high-climate change scenario just applying technical adaptation strategies., En los últimos años multitud de estudios han evidenciado y corroborado la existencia de un cambio climático global. A pesar de la existencia de una gran heterogeneidad regional en el grado y la temporalidad de los posibles impactos del cambio climático, cada vez se conocen mejor cuales pueden ser las tendencias futuras sobre posibles cambios en regímenes de temperatura y precipitaciones y, por lo tanto, en otros impactos indirectos sobre la Biosfera o la Criosfera. En este contexto, las áreas de montaña han sido identificadas como regiones especialmente vulnerables a los efectos del cambio climático y como zonas de gran interés para la detección y evaluación de los posibles impactos. Por otro lado, en las últimas décadas, el turismo de invierno, altamente sensible a los cambios en la meteorología y la disponibilidad de nieve, se ha convertido en una de las principales actividades económicas en muchas zonas de montaña y ha jugado un papel clave y fundamental como fuente de ingresos y desarrollo local. Un claro ejemplo es el caso de los Pirineos, una de las regiones europeas más importantes en lo que se refiere a turismo de invierno después de los Alpes. La motivación principal del proyecto NIVOPYR, proyecto de investigación multinacional en el marco de la Comunidad de Trabajo de los Pirineos (CTP), es evaluar la posible influencia del cambio climático en la evolución del turismo de nieve, y más específicamente el esquí alpino, en esta región. Así, se han realizado diferentes tareas orientadas a integrar el conocimiento ya existente en los patrones presentes y futuros de las temperaturas, precipitaciones, cubierta de nieve y comportamiento de los esquiadores, desarrollar metodologías de análisis y obtener por primera vez datos objetivos para la región Pirenaica. De este modo, se ha obtenido tres perfiles diferentes de estaciones de esquí dependiendo de su vulnerabilidad frente al cambio climático. Un primer grupo de estaciones, identificado como altamente vulnerables, se vería afectado tanto por un escenario de cambio climático medio como por uno más intensivo y, por lo tanto, deberían contemplar la aplicación de medidas de adaptación estructurales, como una mayor desestacionalización y diversificación de su actividad turística. Las estaciones del segundo grupo, consideradas de climábaja vulnerabilidad, podrían seguir operando con medidas de adaptación técnicas bajo un escenario de cambio climático medio, pero no bajo un escenario de cambio climático más intenso. Finalmente, el tercer grupo, engloba las estaciones consideradas como resilientes. Estas estaciones, debido a una situación geográfica y socioeconómica privilegiada frente al resto de estaciones del Pirineo, se verían poco afectadas tanto por un escenario medio de cambio climático como por uno más intenso.

Resilience as a theoretical concept and policy proposition is constantly being redefined and clarified. But when it comes to implementation, public managers and bureaucrats have to take ownership of resilience and translate it into practical forms that make sense to them intellectually and operationally. In this chapter, we first explain how resilience is presented in the literature as, variously, a paradigm change, a governance model to better manage complex issues, and a destination to reach. Second, we analyse how public managers and bureaucrats responsible for implementation in London and Montreal have interpreted and used resilience. Finally, we discuss how paradigm change, governance transformation and goal attainment perspectives end up converging into a relatively similar meaning in both cities. What these cities are lacking to take the next step toward urban resilience is the strategic endorsement of political authorities to support this important transformation.

- Abstract
The use of unstable surfaces during resistance training has demonstrated a maintenance or reduction on force production. However, the use of unstable surface on force variability has not been assessed using non-linear methods that may be better suited to detect changes in movement variability throughout a given movement. Consequently, this study compared the use of stable vs unstable surfaces on force variability during bilateral squats performed with an inertial flywheel device (Eccoteck, Byomedic System SCP, Spain). Twenty healthy men (mean ± SD: age 22.9 ± 2.9 years, height 1.81 ± 0.7 m, body mass 76.4 ± 7.6 kg and 1RM back squat 110.9 ± 19.7 kg) with a minimum of four years in resistance training performed six sets of six repetitions of squats at maximal concentric effort with one minute rest between sets. Force output on the vertical axes was measured using a strain gauge and the results were processed using non-linear sample entropy (SampEn). Results showed no differences for any of the dependent variables between stable and unstable conditions. SampEn showed no differences between conditions (chi-squared = 0.048 P = 0.827), while Force
mean and SampEn presented a small correlation (r = 0.184; p < 0.01). No changes in entropy were found over the course of the series. Together, these results suggest that the structure of force variability between stable and unstable surfaces are similar. This lack of difference between surfaces may be due to postural and anticipatory adjustments. Consequently, by introducing unstable surfaces to the flywheel bilateral squat exercise, practitioners may not observe changes in Forcemean and force variability when compared to stable surface training suggesting that increased training volumes or intensity may be required during unstable environments to cause a desired training stimulus., (Copyright © 2019.

- Abstract
The power grid defines one of the most important technological networks of our times and sustains our complex society. It has evolved for more than a century into an extremely huge and seemingly robust and well understood system. But it becomes extremely fragile as well, when unexpected, usually minimal, failures turn into unknown dynamical behaviours leading, for example, to sudden and massive blackouts. Here we explore the fragility of the European power grid under the effect of selective node removal. A mean field analysis of fragility against attacks is presented together with the observed patterns. Deviations from the theoretical conditions for network percolation (and fragmentation) under attacks are analysed and correlated with non topological reliability measures.
