The role of public policies on sustainable innovation in agri-food value chains
No full textIntroduction
Sustainability in the agri-food sector is essential to ensure reduced pressure on natural resources and good living conditions in rural areas (FAO, 2011). Achieving this objective largely depends on the constant introduction of innovation along the whole agri-food chain (OECD, 2019). Public policies can play a forefront role in this regard (OECD, 2021). However, although many studies and reviews focused on the issues at farm level (especially in relation to agri-environmental measures), little is still explored regarding the impact on the agri-food chain as a whole (Uthes & Matzdorf, 2013). Within such a framework, the aim of this research is thus to investigate the role of public policies in affecting the adoption of sustainable innovation in the agri-food value chains. To this end, a systematic literature review was developed for exploring four key aspects at the basis of the comprehension of such an important theme: i) nature of the policies in place, ii) policy instruments employed, iii) sustainability dimension target of the policy, iv) stages of the chain addressed by the policy.
Data and research methodology
The research was run on Scopus on peer-reviewed articles and reviews, based on title, abstract and keywords. The textual content of the query was: sustainab* AND innovat* AND (agri* OR food*) AND chain AND polic* AND public. Finally, we also restricted the research to specific subject areas.
Discussion of results
The research query led to a selection of 24 articles. However, 7 of them were excluded after a first screening of the abstract. A sample of 17 works was finally analysed for the purposes of the review. The first outcome of the research was that very few authors thoroughly addressed the role played by public policies in orienting agri-food value chains towards sustainability. The present work highlighted also that a large part of the reviewed literature is mostly case study-oriented. However, some authors
approached the research with an even narrower focus, i.e. observing only specific stages of the agri- food chain. Furthermore, many manuscripts only mentioned the existence of specific policy frameworks without providing a comprehensive analysis of the related functioning, objectives and instruments. Although no geographical restriction was set in the research criteria, the main public policy debated in the reviewed works was the EU Common Agricultural Policy. However, at the local level, other policies were also discussed within the reviewed literature. In addition, the main policy instruments debated across the reviewed manuscripts were mostly monetary in nature, but normative and informative instruments resulted largely explored as well. In conclusion, the majority of the reviewed papers investigated the role of public policies in relation to the environmental dimension of sustainability. However, also the economic and social domains resulted largely debated by many authors.
Main conclusions
The outcomes of the present study suggest the possible lack in the literature of a research work thoroughly exploring the role of public policies from a theoretical perspective with a comprehensive view of the agri-food chain. With this regard, the current research represents in fact the state-of-the-art of a more articulated work studying the role of public policies to support sustainability-oriented innovation along agri-food value chains

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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
