Coordination Mechanisms along the Supply Chain: a Key-Factor for Competitiveness
Full text linkThe purpose of this paper is to contribute to a better understanding of the role of relationships between
stakeholders in the supply chain as a potential source of competitive advantage. In the case study, we focus on the
wine industry in the Lazio Region (Italy). We observe a significant loss of competitiveness in this industry and we
suggest that a higher level of communication and different coordination mechanisms among stakeholders could help
in recovering a better market position. We focus on the linkages between farmers and the other food chain
stakeholders through the perspective of Institutional Economics and Economics of Organization, in order to identify
the key factors that determine the competitiveness of the supply chain’s product.
The Lazio wine supply chain is investigated through the analysis of official data, integrated with primary data,
collected through in-person interviews and questionnaires addressed to producers and experts. It emerges that the
wine supply chain in the Lazio Region is characterized by a serious decline, suggested by a sharp decrease in
production and sales, low reputation among experts, widespread negative consumers perception. We interpret this
turn-down through the structural features of the market and through the low level of communication and coordination
between the agents. This leads to the identification of potential instruments able to deal with the difficulties
highlighted. We emphasize the role of public institutions in fostering communication and cooperation among firms
and suggest the potential role of a web portal, in linking sellers and buyers in a common network
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
The Performance of Protected Designations of Origin: An Ex Post Multi-Criteria Assessment of the Italian Cheese and Olive Oil Sectors
No full textProtected designations of origin (PDOs) and protected geographical indications (PGIs) for food products are used by the European Union with the goal of achieving several policy objectives. We build a multi-criteria analysis framework for ex post assessment of the performance of PDOs. The performance criteria are based on five policy objectives, as defined by European policy makers in regulations, with each criterion measured by a set of indicators. We apply the framework to analyze the performance of all Italian PDO cheeses and olive oils from 2004 to 2008. The results show that for the PDOs studied it is feasible, in general, to perform on all five objectives at the same time, although partial tradeoffs are present between the bargaining power and local development objectives on one side and the market performance objective on the other. A ranking of PDOs in the two sectors on all objectives using multi-criteria analysis and equal weights on all objectives shows overall higher performance for smaller PDOs that are well rooted in the territory of origin and targeted to niche market segments. Lower ranked PDOs under this scenario tend to be bigger, older, and better established in wider markets. Alternative weighting scenarios that emphasize niche/local market PDOs or market performing PDOs yield different relative rankings. The results provide insights for both policy makers and stakeholders into the evaluation of PDO policy, as well as into the performance of individual PDO products
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
