Imagining thre future in a difficult present: storylines from spanish youth

This book investigates and explores the complex dynamics of youth in contemporary society, especially in troubled and crisis-ridden contexts. On the one hand, teenagers and young adults experience social suffering, marginalisation, gender and ethnic bias, and an increased risk to be radicalised and involved in extremism and related violence. On the other hand, it is shown that young people are resilient, and they have a remarkable ability to adapt and cope with extremely difficult situations.2017-1

Hydrodynamic identification of NAUTILUS FOWT platform from small scale tests

A small-scale tank test campaign of the NAUTILUS offshore wind floating semisub-mersible platform was held at the Ifremer Deep Water Basin within the framework of the MaRINET 2 project. The support structure consists in four stabilized columns on a square pontoon supporting a generic 8-MW wind turbine. The tests were carried out at 1:36 Froude scale in parked conditions, and the mooring system was modelled as a set of aerial mooring springs providing a nonlinear stiffness. The hydrodynamic characterization of the floater from experimental data was tackled by using traditional techniques in naval architecture), as well as approaches derived from operational modal analysis in the frequency domain, such as the Sub Space Identification—Covariance (SSI-COV) method. The validity of this approach and its potential application to the identification of such kind of structures is discussed against the results of a more traditional technique based on the fitting of decay tests

Dossier. Les sociétés démocratiques en France et en Espagne : fragilités et mutations

El artículo analiza los imaginarios de futuro de la juventud en España. Concretamente, considera el modo en que la crisis ha alterado las viejas certezas acerca de los espacios de su vida adulta en lo que afecta a la búsqueda de su lugar en la sociedad. El «¿si no es aquí, dónde?» surge de forma recurrente, trastocando el marco espacial en el que imaginan sus vidas a corto y medio plazo. La normalización del espacio global y la interiorización de la migración —como posibilidad, deseo o imposición— se añaden a la complejidad y desarticulación de sus transiciones a la vida adulta. El material empírico empleado en el estudio proviene de cartas escritas por estudiantes de universidades públicas españolas en las que relatan cómo les va la vida y sus planes de futuro.2017-1

Imagining the future in a difficult present: storylines from spanish youth

This paper examines Spanish juveniles’ effort to imagine the future in times of uncertainty. The breakdown of youth strategies to adulthood exacerbates the disarticulation of imagined futures. ‘Presentism’ is further intensified by the 2008 crisis, making it difficult for youth to ‘find their place in the world’. Our evidence comes from biographical narratives collected in the form of ‘letters’ written by Spanish university students. Borrowing from literature on youth transitions, temporal sociology and situated culture, we develop a narrative analysis which shows how, in the process of imagining their future, Spanish youth are reconsidering their expectations and generating new solutions. Their accounts show how they manage to connect their individual experiences with the collective, generational dimension.2017-1

Heterotrophic Bacteria Respond Differently to Increasing Temperature and Dissolved Organic Carbon Sources in Two Tropical Coastal Systems

Temperature and substrate availability are important variables controlling marine heterotrophic bacterial activity. However, particularly in tropical regions it remains to be determined how these variables jointly affect bacterial activity. In this study we show how bacterial carbon cycling in two tropical coastal ecosystems (the Great Barrier Reef [GBR, Australia] and the Red Sea [Saudi Arabia]) are influenced by changing temperature (using a 6°C gradient) and the addition of dissolved organic carbon (DOC) from different sources (addition of mangroves and seagrass leachates, plus natural seawater). Our study demonstrates that elevated temperatures in the GBR increased bacterial organic carbon processing, while in the Red Sea no clear effects were found. More of the added DOC was degraded in the Red Sea but this additional carbon did not increase the biomass production, due to low bacterial growth efficiencies in all treatments. In addition, increasing temperatures in the GBR resulted in lower bacterial growth efficiencies, while no clear impact were found in the Red Sea. In conclusion, this study suggests that site-specific ecosystem differences (e.g., different microbial and macrophyte community composition) may override general responses to temperature and substrate in tropical coastal waters.The authors would like to thank the SeaSim team at AIMS and the Coastal and Marine Resources Core Lab at KAUST for the help with setting up the experiments.
