Virulence pattern in Danish races of common bunt (Tilletia caries) Common Bunt
No full textBy harvesting fungal spores from partly resistant varieties (as is the practise in normal organic seed production and farming), virulent races of common bunt builds up to devastating levels. The experiment shows that virulence against rare resistance genes to common bunt might be more frequent than expected, since European resistance screening so far have been done without preselecting of virulent races
Innovative approaches to embed diversity in food systems: DIVERSFOOD outcomes from field to plate
Full text linkUnderutilised crops are offering opportunities to diversify and improve farming and food systems as a response both to climate change and to social changes in food culture and uses. The choice of seed greatly determines farming practices and all stages of the food supply chain right up to the consumers’ plate.
Based on DIVERSFOOD outcomes, this Booklet #6 proposes a number of thought-provoking concepts, methods and tools. It aims to inspire stakeholders who wish to develop diversity in food systems, presenting 10 novel ideas and approaches that support innovation embedding diversity in food systems from the field to the plate
Recherche multi-acteurs et transdisciplinaire pour des systèmes alimentaires bio et locaux
No full textL'agriculture biologique connaît un fort développement mais peu de recherches lui sont dédiées en France. La notion d'agriculture biologique regroupe des conceptions très diverses dans un contexte d'agriculture conventionnelle dominante et d'une politique de « transition agroécologique ». La biodiversité cultivée, réduite par l'intensification de l'agriculture, est la clé de la performance des agrosystèmes « bio » basés sur le respect et la maximisation des processus vitaux. Pour pallier le manque de variétés adaptées et diversifiées, une collaboration avec les paysans « bio » a été initiée. Cet article présente les expériences et les évolutions du métier d'«ingénieur du vivant » élargi aux systèmes alimentaires locaux et leurs acteurs, avec une approche transdisciplinaire et multi-acteurs.Organic farming is growing apace, but little research is specifically dedicated to it in France. The organic approach unites a range of different concepts in an agricultural context dominated by conventional farming and a policy of "agro-ecological transition". Cultivated biodiversity has shrunk by intensification of agriculture for a century, yet is key to the performance of organic systems founded on respect for, and optimization of, natural processes. To overcome the lack of well-adapted, diverse varieties, a collaboration with organic farmers was initiated. This paper describes the experience of these professional ”Engineers of Life", and how their activities have evolved, with a look at local food systems and their stakeholders through a transdisciplinary, multi-actor approach

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
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
