Este trabajo analiza la evolución de la coautoría en España en Ciencias Sociales para el periodo 2000-2013. El objetivo es explorar hasta qué punto están justificadas las limitaciones en número de autores que establecen las distintas agencias de evaluación españolas. El análisis de 11681 trabajos españoles de investigación en 20 categorías temáticas de las ciencias sociales revela que no hay inflación en el número de autores, que el tamaño de los equipos es homologable al de los trabajos internacionales en las mismas áreas y que el número de firmantes depende de la colaboración institucional y del nivel de internacionalización de los equipos. A excepción de los trabajos en Antropología y en Educación especial, el número de autores no es superior a cuatro. Sin embargo, son los trabajos con mayor número de autores los que obtienen un impacto mayor. El estudio evolutivo muestra una tendencia muy importante al alza en el tamaño de los equipos. En conjunto, estos resultados sugieren que carece de utilidad la limitación administrativa del número de firmantes que, con independencia de su eficacia en combatir la autoría honoraria, puede ir en perjuicio de la colaboración, la internacionalización y el posterior impacto de los trabajos.

Working paper
International audience ; The aim of the next negotiations between Parties until the Twenty-first Conference of Parties (COP 21) which will be held in Paris in 2015 is to reach an international agreement involving as many countries as possible, in order to reduce CO2 emissions sufficiently and stay in line with the ultimate 2°C objective of the UNFCCC. A strong climate policy in line with this 2°C objective requires a global contribution, whether countries are industrialized or developing, or especially fast developing or emerging. However, debates highlights the fact that it is primarily up to industrialized countries to keep their promise of helping countries develop a record of adapting to the impacts of climate change, and nothing is certain as regards the possible level of CO2 emission reduction that developing countries will be able to attain or, even, accept to reduce. In terms of cost, a larger contribution from developing countries is less expensive than strong emission mitigation in industrialized countries, as expressed by the decision to allow flexible mechanisms under the Kyoto Protocol (i.e. develop GHG emissions mitigation projects where the carbon abatement cost can be lower). But this is not sufficient. Could we reach an ambitious, and necessary, climate target without the participation of developing countries? In the same manner, a key feature of the Copenhagen agreement and of the future accord is the participation of the United States of America and non-Annex I countries, especially China, as they represent a large share of global CO2 emissions. China and the USA are the largest global emitters of CO2 and, as concerning developing countries, without their participation in a climate agreement the latter cannot really ensure achieving stabilized CO2 concentration and global temperatures. Various climate scenarios are implemented in the bottom-up optimization model TIAM-FR and analyzed to explore the effects of a possible international coordination on main environmental and economic indicators. ...

Various climate scenarios are implemented in the bottom-up optimization model TIAM-FR and analyzed to explore the effects of a possible international coordination on main environmental and economic indicators. The impacts of different commitment levels under post-Copenhagen and/or global long-term climate policies can thereby be discussed and provide some understanding on the stakes and issues. Particularly, do developing countries have the capacity to implement policies to reduce emissions given that their priority is development and energy supply? What is expected from industrialized countries like Europe? What are the technological possibilities considering the state of development of their energy systems and the evolution of their needs? The main focus is, in a first part, on the ambition of the various climate policies regarding CO2 emissions at global and regional level. In a second part, we discuss the impact of international climate change strategies to the energy system, and particularly on the electricity generation In this context, discussions investigate long-term solutions, and particularly the development of CCS technologies or renewables, in response to a constraint that influences the energy mix.

We propose institutional mobility indicators based on researchers' mobility flows in 22 major fields of science across 1,130 Leiden Ranking institutions from 64 countries. We base our indicators on data from the Dimensions database and Global Research Identifier Database. We use researchers' first and last affiliations to estimate the extent authors have moved across institutions as well as countries. For each institution, we quantify the shares of researchers with the same affiliation (insiders), those who came from another institution within the country (domestic outsiders), and those coming from a different country (foreign outsiders). Institutions in Central, Eastern, and Southern Europe have the highest share of insiders, whereas institutions in Northern America and Western and Northern Europe have a higher share of foreign outsiders. Foreign outsiders are most common in small and wealthy countries. No disciplinary differences are observed, as captured by the field classification scheme of Dimensions.
Every year, over 40% of the total energy consumed in Europe is used for the generation of heat for either domestic or industrial purposes whereas the cooling demand is growing exponentially. The importance of the heat and cooling sector is underlined in the EU energy policy initiatives. This emphasize the role of technologies based on renewable energy sources combined with highefficiency energy technologies, to meet the heat and cooling demand in Europe more sustainably in the future. In this context, the JRC led study, which was undertaken with two partners1, to identify the current best available technologies (BATs) which can contribute to improve the energy efficiency and reduce the CO2 emission in the heat and cooling market in the EU ; Godkänd; 2012; Bibliografisk uppgift: JRC72656; 20130423 (kroann)

We present a forecasting analysis on the growth of scientific literature related to COVID-19 expected for 2021. Considering the paramount scientific and financial efforts made by the research community to find solutions to end the COVID-19 pandemic, an unprecedented volume of scientific outputs is being produced. This questions the capacity of scientists, politicians and citizens to maintain infrastructure, digest content and take scientifically informed decisions. A crucial aspect is to make predictions to prepare for such a large corpus of scientific literature. Here we base our predictions on the ARIMA model and use two different data sources: the Dimensions and World Health Organization COVID-19 databases. These two sources have the particularity of including in the metadata information on the date in which papers were indexed. We present global predictions, plus predictions in three specific settings: by type of access (Open Access), by NLM source (PubMed and PMC), and by domain-specific repository (SSRN and MedRxiv). We conclude by discussing our findings. ; Paper accepted for oral presentation at the ISSI Conference 2021.

Green plants (Viridiplantae) include around 450,000-500,000 species(1,2) of great diversity and have important roles in terrestrial and aquatic ecosystems. Here, as part of the One Thousand Plant Transcriptomes Initiative, we sequenced the vegetative transcriptomes of 1,124 species that span the diversity of plants in a broad sense (Archaeplastida), including green plants (Viridiplantae), glaucophytes (Glaucophyta) and red algae (Rhodophyta). Our analysis provides a robust phylogenomic framework for examining the evolution of green plants. Most inferred species relationships are well supported across multiple species tree and supermatrix analyses, but discordance among plastid and nuclear gene trees at a few important nodes highlights the complexity of plant genome evolution, including polyploidy, periods of rapid speciation, and extinction. Incomplete sorting of ancestral variation, polyploidization and massive expansions of gene families punctuate the evolutionary history of green plants. Notably, we find that large expansions of gene families preceded the origins of green plants, land plants and vascular plants, whereas whole-genome duplications are inferred to have occurred repeatedly throughout the evolution of flowering plants and ferns. The increasing availability of high-quality plant genome sequences and advances in functional genomics are enabling research on genome evolution across the green tree of life. ; Alberta Ministry of Advanced Education; Alberta Innovates AITF/iCORE Strategic Chair [RES0010334]; Musea Ventures; National Key Research and Development Program of China [2016YFE0122000]; Ministry of Science and Technology of the People's Republic of ChinaMinistry of Science and Technology, China [2015BAD04B01/2015BAD04B03]; State Key Laboratory of Agricultural Genomics [2011DQ782025]; Guangdong Provincial Key Laboratory of core collection of crop genetic resources research and application [2011A091000047]; Shenzhen Municipal Government of China [CXZZ20140421112021913/JCYJ20150529150409546/JCYJ20150529150505656]; National Science FoundationNational Science Foundation (NSF) [DBI-1265383, IOS 0922742, IOS-1339156, DEB 0830009, EF-0629817, EF-1550838, DEB 0733029, DBI 1062335, 1461364]; National Institutes of HealthUnited States Department of Health & Human ServicesNational Institutes of Health (NIH) - USA [1R01DA025197]; Deutsche ForschungsgemeinschaftGerman Research Foundation (DFG) [Qu 141/5-1, Qu 141/6-1, GR 3526/7-1, GR 3526/8-1]; Natural Sciences and Engineering Research Council of CanadaNatural Sciences and Engineering Research Council of Canada ; The 1KP initiative was funded by the Alberta Ministry of Advanced Education and Alberta Innovates AITF/iCORE Strategic Chair (RES0010334) to G.K.-S.W., Musea Ventures, The National Key Research and Development Program of China (2016YFE0122000), The Ministry of Science and Technology of the People's Republic of China (2015BAD04B01/2015BAD04B03), the State Key Laboratory of Agricultural Genomics (2011DQ782025) and the Guangdong Provincial Key Laboratory of core collection of crop genetic resources research and application (2011A091000047).
