Ethics, Sustainability and Logistics in Agricultural and Agri-Food Economics Research
No full textThe work analyzes the changes in agri-food system, with the advent of logistics management of the flow of goods and information along the food supply chain. Continues with the analysis of agri-food functions and responsibilities towards society. This field of research has been widely explored in recent years, following the development of the Corporate Social Responsibility (CSR) certification in agribusiness. The analysis starts by examining the coherence of the ethical basis of human choices in a homo oeconomicus framework, where social relationships are merely exploitable activities. CSR development is then studied in the light of the new stakeholder theory for firms. With reference to sustainable development, the main fields of economic research and the most important goals achieved are examined. The analysis ends with some remarks on the methodological perspectives of agricultural economics research, with reference to the arguments discussed here
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
Environmental life cycle assessment for improved management of agri-food companies: the case of organic whole-grain durum wheat pasta in Sicily
No full textPurpose: This study was developed to address the environmental issues associated with a high-quality pasta production process, as the essential starting point to identify the related hotspots and the feasible improvement potentials. Methods: To this end, a life cycle assessment (LCA) at the food producer’s gate was performed. Primary data were collected in a small-size Sicilian pasta factory located in Fiumefreddo (Sicily), where organic ‘Senatore Cappelli’ durum wheat landrace is cultivated and later is processed into whole-meal semolina and pasta, whilst secondary data were extrapolated from Ecoinvent v. 3.5 database, as available in the SimaPro 9.1.0.11 software. The environmental profile of pasta was assessed by adopting the Impact Assessment Method (IAM) that is required for use in case of Environmental Product Declarations (EPDs). This is the EPD 2018 v. 1.01, as one of the European IAMs contained in the aforementioned SimaPro software. The environmental profile of pasta was analysed in terms of four different impact categories, namely global warming, eutrophication, acidification, and photochemical oxidation, as recommended by the PCR 2010:01 Uncooked pasta, developed in the framework of the International EPD System. Results: The obtained results, expressed in the form of equivalent indicators, suggest that cultivation is the phase contributing the largest impacts for all the midpoint categories considered by the LCIA method. In addition, it was observed that the contributions assessed in this study are highly comparable and aligned with those contained in the EPDs published in the pasta sector, specifically for the cultivation phase, which performs similarly to the only case of organic pasta EPD amongst those developed. Conclusions: At the end, the study suggested that the cultivation of ancient varieties and landraces in organic and low-input farming systems have a large potential for reducing the environmental impact of pasta. Finally, although specific, the results of the study may be of interest to researchers, LCA practitioners, farmers and producers, policymakers, and other stakeholders, and could support the implementation of environmental labels
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
