Editorial: Biodistricts: a concrete example of sustainable food systems
Full text linkBiodistricts are territories where farmers, citizens, public authorities and other local actors realize a formal agreement aimed at the sustainable management of local resources, based on the principles and model of organic farming and on the agroecological best practices, in order to boost the economic and socio-cultural development of their community. This Research Topic focuses on understanding the role of biodistricts in enhancing the sustainability of food systems and whether or how they represent a concrete example of sustainable food systems. Different examples from around the world, and different analytical approaches, have been provided by the studies included in this topic
Presentations from the HoReCa Forum International Sessions at the BioFach Congress 2013
No full textThe HoReCa Forum (Hotels, Restaurants & Catering Forum) is one of the Forums of the German BioFach Congress. Within this Forum there are a number of English presentations on various aspects of the organic out-of-home sector in Europe and abroad. At this Forum colleagues presented current information on Green Public Procurement, certification of organic horeca and some international case studies about organic school meals.

Certifying Out Of Home Operators in Europe. European Forum for Certification.
No full textFor the 7th consecutive year a session on organic certification of out-of-home operations was held at the BioFach in Nuremberg, February 2010. The focus on organic catering in Europe is a growing movement. A number of standards and statements are presented thus adding to the sharing of information, experiences and inspiration across borders and organisations. It is hoped that this exchange will facilitate beneficial contacts between those involved in the setting up and development of national and private catering certification standards.
The mass catering sector is growing and therefore attracts increasing attention at pan‐European level; The EU regulation for organic food and farming (EC No 834/2007) which came into force on January 1st, 2009, obliges the European Commission to report to the EU Council on the
scope of the regulation before the end of 2011, with a clear reference to ‘organic food prepared by mass
caterers’. Moreover, a Communication from the Commission to the European Parliament, the Council, the European Economic and Social Committee and the Committee of the Regions of 16 July 2008 on ‘Public procurement for a better environment’ opens up for promoting an increased consumption of organic food and farming products as tools to mitigate climate change. In the following pages the presentations given at the BioFach session on certification of out‐of‐home
catering are to be found
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
