TWO DECADES OF EARTH SCIENCE RESEARCH
Get PDFIn 2012, the Évora Geophysics Centre (CGE) celebrates 20 years of activity. In
these two decades, the national scientific system underwent a profound
transformation, new organizational structures appeared, and participation in
structures and international networks, and scientific integration reached very high
levels. The national scientific environment is now more qualified and competitive;
however the available funding per researcher became scarcer.
Currently the CGE team includes 67 full members, and is organized in two
main Lines of Research: (1) Atmosphere and Hydrosphere, (ii) Solid Earth. The first one
comprises the centers of activity: Meteorology & Climate, Water, Environment, & Surface
Processes, and Energy & Flow Structures, while the latter is composed of the centers of
activity: Active Tectonics & Risks, Lithosphere, Mantle & Geological Resources, and
Heritage & Archeometry.
The time of maturity has come for GCE as a research unit, with a growth
trajectory that was not always linear; however it has been progressive with respect to
scientific quality, organizational structure, and the scientific and training outputs that
were made available to the community.
It is also the time to reflect on the past and to define future strategies. This
debate is carried out within the evolving framework in which the CGE develops its
activity. Actually, CGE faces new challenges on the times ahead. At the national
level new rules of public funding have been announced, which are expected to
increase competition for national funding, together with a strong pressure to make
networking among the teams for the use of the available facilities. At the
international level, CGE is challenged to collaborate with national and international
teams to get access to the new European funding program HORIZON 2020.
The workshop “Two Decades of Earth Science Research” was held at the
University of Évora, on 23 November 2012, as the closure of the Program of
Celebrations, which spanned over the year of 2012. For this workshop we invited
national and international key figures as "keynote speakers", and other colleagues,
which with us will reflect on the evolution of Earth Sciences, Atmosphere and
Hydrosphere, and the national and European science on these two decades. With
this initiative we will also make our contribution to the community for the analysis
of this framework and define new directions for the scientific activity
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Variations on the Author
Get PDF“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
Get PDFWe 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
Jornadas de Física por ocasião da jubilação do Professor Rui Namorado Rosa
No full textForeword
This book is a tribute to Professor Rui Manuel Vassalo Namorado Rosa at the end of his career as a distinguished Professor of Physics of the University of Évora. Al- though Professor Rui Rosa’s main work has focused on research and academic activi- ties, in particular as Vice-Rector and Chairman of the Scientific Council of the Uni- versity of Évora, his rich curriculum vitae encompasses many other activities ranging from social interventions and citizenship, science communication, and participation in debates of international significance. His ever recognized friendliness and helpful- ness granted him many friends that have beneficiated much from his wise advice, far- sighted views, open-minded judgment, and well-based opinions. His work and com- mitment with the University of Évora has much contributed to research, teaching development, and internationalization of different fields of this University. This is why Professor Rui Rosa, who acts and considers himself as an ordinary man, got the respect and esteem of so many people and deserved the tribute that the Academia has decided to celebrate his retirement.
Professor Rui Rosa graduated in Physics and Chemistry in the University of Lis- bon (1961), got his PhD in Plasma Physics from the University of Oxford (1969). From 1961 to 1983 he did research at the Physics and Nuclear Engineering Labora- tory (LFEN/LNETI) in Lisbon. Since 1983 to June 2010 he was Full Professor of Physics at the University of Évora. His diversified publication list includes the early works on plasma physics, works on conventional energy and renewable energy re- sources and technologies, as well as recent works on energy policy, together with es- says on the educational and social impacts of science and technology.
This book includes three essays, namely on the organizational aspects of science, nuclear energy, and rational thinking, together with the contributed papers by the au- thors that participated in the workshop “Jornadas de Física” held at the University of Évora, on 15-16th June 2010, as a part of the celebration of Professor Rui Rosa’s retirement.

The IV International Conference on Oil and Gas Depletion
No full textThe IV International Workshop on Oil and Gas Depletion, that is held at Gulbenkian Foundation in Lisbon on the 19th and 20th May, 2005, is the fourth annual meeting promoted by ASPO, the Association for the Study of Peak Oil and Gas, with the organizing support of Geophysics Centre of Évora.
Previous meetings were held at the University of Uppsala in 2002, Institut Français du Pétrole, Paris in 2003, and Bundesanstatt fur Geowissenschaften und Roshtoffe, Berlin in 2004.
In this fourth annual edition, the core topics chosen for our works are:
• Reality in Oil Exporting Countries: The Supply Limits
• Impacts of Depletion in Oil Importing Countries: The Demand Pressure
• How-Much Regular Oil and Non-Conventional Oil: Utopia versus Reality
• The Case for Political Action: The Depletion Protocol
• The World Past Peak Oil Age
From Uppsala to Lisbon, the public perception of the serious threat impending on humankind as a result of the growing scarcity of fossil fuels has increased. And national and international authorities have slowly but perceptibly admitted and changed their discourse on the problematic availability of the energy required to run the world economy. But political consequences have not yet been addressed straightforwardly – when political action is ever increasingly urgent for putting in place the economical and social changes and technological infrastructure required for preserving wellbeing if not survival itself.
For this reason, in this fourth edition of ASPO’s annual meetings we called upon members of the political community to share their views on how political action might be taken at the required international level. As the starting point of this debate we have the Depletion Protocol - first proposed by Colin Campbell 10 years ago at a conference in London. It has surfaced in various guises since, named the Uppsala Protocol in 2002, on the occasion of the First International ASPO’s Workshop, later also referred to as the Rimini Protocol.
The organizers of this Workshop welcome all participants and thank all speakers who kindly accepted to contribute to this event and those participants who also offered their contributions.
They thank Calouste Gulbenkian Foundation and Partex – Oil and Gas, for generously hosting this event and offering the valuable sponsorship which makes it possible.
Thanks are also due to the staff of the Geophysics Centre of Évora and University of Évora who, along the past few months, has worked in preparation of the conditions to hold this event now and who, together with the staff of Gulbenkian Foundation, are making it through.

Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
