Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
2010-2020 : une décennie décisive pour l'avenir du climat planétaire
No full textThe long term future of the planet's climate will depend of the policies implemented in the next decades. While economic development in the last two centuries has been based on an intensive use of fossil energy resources, the major challenge for the XXIst century is the transition towards low carbon energy systems. This will impose drastic changes in the dynamics of some fundamentals variables of energy development in every region, in particular the energy intensity of GDP and the carbon intensity of the energy mix. The accumulation of greenhouse gas in the atmosphere and consequently the climate for the future generations will directly depend of the capability of the international community to implement the required changes in economic development patterns.L'avenir du climat planétaire à long terme se jouera au cours des prochaines décennies. Alors que le développement économique s'est fondé depuis deux siècles sur le développement massif des énergies fossiles, la question majeure pour l'énergie au XXIe siècle est certainement celle de la transition vers des systèmes énergétiques bas carbone. Cela supposera des transformations profondes, voire des ruptures, dans les variables structurelles qui caractérisent le développement énergétique de chaque région du monde, en particulier l'intensité énergétique du PIB et l'intensité en carbone du mix énergétique. L'accumulation des gaz à effet de serre dans l'atmosphère et donc le climat pour les générations futures dépendra directement de la capacité de la communauté internationale à se mobiliser pour mettre en œuvre rapidement les bifurcations nécessaires
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

KPI-ETS: Kyoto Protocol Implementation - impacts of JI and CDM on the European ETS
No full textThis report analyze the impacts of linking JI and CDM to the future European Emission Allowance Trading System (ETSy). The result indicate that the volume of credits obtained through JI and CDM projects by the enlarged EU Emission Allowance Trading Scheme, as well as the magnitude of cost savings and allowance price impacts will crucially depend on how much competition there will be from EU Member States
and other countries in JI and CDM credits
GECO 2015 - GHG and energy balances
Full text linkThis document complements the GECO2015 Report. It provides the detailed GHG and energy balances for the Baseline scenario and for the Global Mitigation scenario described in the main report. The tables provide for each country and region:
- the main economic indicators: population, income per capita, share of sectoral value added;
- the international energy prices;
- emissions per greenhouse gas (GHG) and sector;
- a reduced energy balance: primary energy production, net trade, primary energy demand;
- power generation: inputs , production, capacity;
- final consumption per sector and per fuel.JRC.J.1 - Economics of Climate Change, Energy and Transpor
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
