Advancing organic and low-input food. QLIF Integrated Research Project
No full textThe Integrated Project “Improving quality and safety and reduction of costs in the European organic and low input supply chains” (QLIF) was funded by the European Commission under the 6th Framework Programme for Research and Technological Development. QLIF started in 2004 with 31 scientific and industry partners and supplemented the consortium with another five partners via open calls. The total budget was 18 million € of which the European Commission contributed 12.4 million €. The duration of the project was five years. The scope of QLIF was on quality and safety of organic and low-input foods in the context of cost efficiency and sound environments. Sixty-one work packages provided conclusive answers based on comprehensive analyses from scientific experiments, socio-economic data and complex modelling. The work was organized in 7 subprojects with interdependent aims. Here an outline is given on what the Integrated Project QLIF has achieved and what challenges remain. Individual subproject folders provide a further insight to the outcomes and a substantial amount of QLIF publications are available in the open access database Organic Eprints
Givtig blanding af forskere og græsrødder ved økologi-kongres i Australien
Full text linkInternational Society of Organic Agriculture Research (ISOFAR) afholdt sin første videnskabelige konference d. 21.-23. September 2005 i Adelaide, Australien. ISOFAR konferencen blev holdt samtidig med 15th IFOAM Organic World Congress: Shaping Sustainable Systems og 8th International IFOAM Organic Viticulture and Wine Conference. Der var omkring 1000 deltagere fra mere end 50 lande til hele arrangementet, heraf knap 25 danskere, flest forskere. Der var 11 danske indlæg og 3 postere på ISOFAR-delen og 8 danske indlæg og 3 postere på IFOAM-delen - så Danmark var godt repræsenteret
Transport, trading and retailing. QLIF subproject 6: Development of strategies to improve quality and safety and reduce costs along the food supply chain
No full textOne of the aims of QLIF subproject 6 was to provide a better understanding of the supply chain performance and the collaboration system of organic supply chains. A notable finding was that supply chain actors with a high collaboration index outperformed respondents with a lower collaboration in terms of overall, non-financial and financial performance. Also, there is evidence that the higher the perceived risk for quality and safety is, the higher the probability that collaborative practices were in place. Nevertheless, overall, the level of collaboration is still too low. In a second part of QLIF subproject 6, HACCP case studies and training courses have been developed with special reference to organic agriculture. A HACCP approach to food safety management can be applied throughout the food chain, from farm to fork. Although a HACCP approach is not a legal requirement in primary production in the EU, it is recognised as an effective and logical means for food safety control that is equally applicable to agriculture including organic and low-input production systems
Decreased rhizodeposition, but increased microbial carbon stabilization with soil depth down to 3.6 m
Full text linkDespite the importance of subsoil carbon (C) deposition by deep-rooted crops in mitigating climate change and maintaining soil health, the quantification of root C input and its microbial utilization and stabilization below 1 m depth remains unexplored. We studied C input by three perennial deep-rooted plants (lucerne, kernza, and rosinweed) grown in a unique 4-m deep RootTower facility. 13C multiple pulse labeling was applied to trace C flows in roots, rhizodeposition, and soil as well as 13C incorporation into microbial groups by phospholipid fatty acids and the long-term stabilization of microbial residues by amino sugars. The ratio of rhizodeposited 13C in the PLFA and amino sugar pools was used to compare the relative microbial stability of rhizodeposited C across depths and plant species. Belowground C allocation between roots, rhizodeposits, and living and dead microorganisms indicated depth dependent plant investment. Rhizodeposition as a fraction of the total belowground C input declined from the topsoil (0–25 cm) to the deepest layer (360 cm), i.e., from 35%, 45%, and 36%–8.0%, 2.5%, and 2.7% for lucerne, kernza, and rosinweed, respectively, where lucerne had greater C input than the other species between 340 and 360 cm. The relative microbial stabilization of rhizodeposits in the subsoil across all species showed a dominance of recently assimilated C in microbial necromass, thus indicating a higher microbial stabilization of rhizodeposited C with depth. In conclusion, we traced photosynthates down to 3.6 m soil depth and showed that even relatively small C amounts allocated to deep soil layers will become microbially stabilized. Thus, deep-rooted crops, in particular lucerne are important for stabilization and storage of C over long time scales in deep soil
Horizontal activites. QLIF subproject 7: Horizontal activities
No full textQLIF subproject 7 represents four horizontal activities common to the project, namely: • Environmental and sustainability audits • Cost-benefit analyses and socio-economic impact assessments • Dissemination and technology transfer • Training of graduate and postgraduate researchers Activities in the horizontal research have shown that organic crop production systems generally are more energy-efficient and have lower greenhouse gas emissions than the conventional production. In terms of dissemination the QLIF website has been central and the QLIF newsletter has attracted more than 1000 subscribers. Coupling of the website with the open access database Organic Eprints provides a prospective source of project information that can be accessed also by future stakeholders in organic and low-input systems. Training events arranged annually for students have contributed to proliferation of skills and knowledge gained in QLIF. Also, these events have served to mediate the attitude needed for research in organic and low-input farming
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
