Integrated Protection and Production in Viticulture
These last years were marked by increased problems of flavescence dorée in vineyards
leading to an increased activity of our research group on it, and the emergence of new models,
as well as the arrival of Lobesia botrana in the United States and of Drosophila suzukii in
Europe. I hope we will contain any invasion of pierce disease in Europe in the vineyards.
I wish we would see one day efficient biological agents against pathogens, and soon the
development of molecular tools for early diagnostics in the vineyards and in reservoir host.
It is noteworthy that new organisation of the meetings with a plenary session dedicated to
IPM allowed to exchange more between entomologist and pathologist and I hope it was in
favour to the transfer of the knowledge and methods into practice.
We had the pleasure during these last meetings to see more countries participating,
especially people outside from the WPRS area, which highlights how the European viticulture
and vine protection is attractive and our group is active. I sincerely thank my colleagues who
helped me during these years for managing the different sub-groups: Cesare Gessler, Hans
Kassemeyer, Andrea Lucchi, Michael Meixner, Denis Thiery, Tirtza Zahavi, Carlo Duso, and
Christoph Hoffmann. I greatly appreciate their help and experience in animating the meetings,
in sharing their knowledge, in reviewing the papers, but also their friendship which makes our
IOBC meetings so friendly. I also would like to thank our two liaison officers Sylvia Blümel
and Mauro Jermini who were or are the warrantors of the IOBC institution. But of course, the
group is there because people dedicate a lot of their time to organise the meetings. Then I
would like to give a particular thank to Hans, Denis, Cesare, Gudrun and all their staff, for
organising the meetings, taking the financial risk, to make them so that we only keep in
memory the beautiful adventures of sharing knowledge and good wines and of encounters
with local people involved into viticulture and passionate by it.
This bulletin is the shortest we had since these last seven years (Figure 1) and it
highlights that because the stakes of science are increasingly competitive it became more
complicated to publish in grey literature. Maybe more systematic publications or special
issues in the Biocontrol journal or others could help to perpetuate the production of our
IOBC-WPRS group.
The reduction of pesticides and Biological control, which is the heart of IOBC-WPRS, is
becoming more and more evident in the European legislation, especially for viticulture. But it will probably be necessary for our
group to open up to new themes such as plant-pathogen interactions, varietal resistance,
biodiversity, ecology, precision viticulture, diagnostic tools and participatory science. Our
winegrowers are always more innovative to make new wines, let us be the same for an agroecological
viticulture
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
Dispelling the Myths Behind First-author Citation Counts
We 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
We 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
