Global, Regional and Local food chains: an assessment of sustainability performance of wheat-to-bread chains across Italy and the UK
Get PDFAbstract – A growing number of consumers are concerned with the impacts of consumption choices. Local food supply chains are increasingly being discussed for their potential to overcome the impacts of global and more industrialized chains. However, opposition between local and global food systems is being questioned and distinctions are ambiguous. Can sustainability performance be assessed in relation to local and global food chains? This paper develops a comparative assessment of wheat-to-bread supply chains. Key attributes are selected to collect data for measuring the performance of supply chains along the global-local continuum within five sustainability dimensions. Using a participatory approach, the research explores stakeholders’ perspectives on sustainability of these chains and assesses the contribution of supply chains of different lengths towards sustainability objectives. The most relevant attributes and the relations (correlations and trade-offs) between them are highlighted. The analysis sheds light on sustainability performance and the participatory assessment reveals conflicting perceptions of sustainability and how this is perceived along the local-global continuum
Identifying food policy coherence in Italian regional policies: The case of Emilia-Romagna
Get PDFAchieving a coherent set of food-related policies is a challenge for policymakers worldwide, as food matters are addressed at more than one level of governance and across several policy domains. Policies in different domains can sustain each other by sharing the same objectives and actions or they can hinder each other, resulting in different levels of coherence. Focusing on the case study of the region Emilia-Romagna (Italy), the present research aims to answer the following research questions: to what extent is food mentioned in regional policies? Are the food-related objectives of Emilia-Romagna policies coherent with each other? Mixed methods were used in three subsequent research steps. Step 1 consisted of collating an inventory of regional policies where food is present. In Step 2, identified policies were analysed with quantitative content analysis, to examine their ob- jectives, degree of targeting, which food supply chain step they focus on, and which policy instrument type they plan to use. Step 3 aimed to assess the coherence of the identified food-related policies’ objectives among each other through expert interviews, analysed with thematic coding. Overall, regional policies reached a good degree of coherence around the common intention of making Emilia-Romagna thrive economically. However, some level of incoherence is present, as a systematic process that lowers incoherence in policymaking is not in place yet. Therefore, implementing the use of a Policy Coherence Matrix as a standardised practice for policy approval is recommended to coordinate food-related policies
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
