Assessing the level of collaboration in the Egyptian organic and fair trade cotton chain
Full text linkThere is rising interest in collaboration among supply chain partners in food and fibre supply chain management studies. In organic and fair-trade chains, collaboration is rooted in both principles and current practices. A tool for assessing collaboration in the food and fibre sector has not been developed to date. To fill this gap a collaboration index has been adapted to the Egyptian organic and fair trade cotton supply chain. A factor analysis has been performed to this end. Two factors emerged within each of the three constructs defining the collaboration index: information sharing (price information and logistics), decision synchronization (exception management and general management) incentive alignment (risk sharing and technical support). The study contributes to defining a method for designing specific collaboration indexes in different food and fibre chains. The index provided relevant context-related information supporting the collaboration strategies in the Egyptian organic cotton chain

Motives for buying local, organic food through English Box Schemes
No full textThe aim is to explain the growing interest of English consumers in local organic food sold through box schemes, by providing insights into the motives of customers of such schemes and examining the relationship with their awareness about problems of the agro-food system.
A mixed methods approach combined in-depth interviews with 22 box scheme customers with a quantitative survey of 416 consumers, analysed by means of Principal Component Analysis (PCA) and an Ordered Logit model.
Consumers of small local organic box schemes in England are both altruistically and hedonistically motivated. This includes a strong political motivation to change the current food system, as shown by the strong influence of an anti-globalisation factor and wanting to support small farmers. They perceive local organic food as a more environmentally sustainable alternative to the mainstream food system. The box schemes offer consumers a practical alternative by providing high quality products combined with convenience, illustrating the importance of the latter also in local food shopping. This reinforces the possibility to successfully combining the attributes of ‘local’ and ‘organic’.
The study was conducted in only one country (England) with about 400 consumers of ten organic farmer-led box schemes. It was based on a self-selecting sample of consumers of such schemes, which included a large proportion of females and people with high level of education. Further research is needed to validate the results.
This study is the first academic study investigating the main factors affecting consumers’ choice to purchase local organic food through a number of English box schemes. It identifies that such consumers are ethically and politically motivated and show some differences compared with the general literature on organic food consumption
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
