Evaluating the environmental impact of agri-food waste reduction: a bibliographic analysis and conceptual framework
No full textIncreasing concerns about the environmental impact of agri-food waste (AFW) have strengthened the need to assess the environmental performance of AFW reduction. Yet comprehensive literature reviews in this area remain scant. This paper presents a review of the research using a bibliographic analysis. Based on a sample of 171 research articles, we proposed a conceptual framework for evaluating the environmental impact of AFW reduction. The contribution of this review is threefold. First, a bibliographic analysis and semi-structured interviews are utilized to systematically review relevant literature and to propose a conceptual framework, which draws on existing research to determine ways of assessing the environmental impacts of AFW reduction. Second, our identification of four overarching research themes with respect to studies on the environmental impacts of AFW reduction offers fresh insights into AFW studies. Third, our conceptual model is refined following the semi-structured interviews we conduct, which serves to reveal the practical implications of our findings and research opportunities for the future.</p
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
Text mediation and collaborative meaning-making: Language support for an EAL academic author
No full textWriting for international publication in English poses considerable discursive challenges for EAL (English as an additional language) academics. In non-Anglophone settings, where assistance is limited, many turn to local English teachers at their university for ad hoc language support. However, the impact of these part-time text mediators on specialized texts is uncertain and doubts persist about their capacity to understand and shape meaning beyond language. This case study investigates how a language mediator helped a Chinese hematologist to convey his intended meaning when revising a submission for a medical journal. We show how mediator-author collaboration draws on their respective expertise to shape academic texts. While the mediator’s independent revisions mainly fixed language issues, her interaction with the author effectively addressed deeper structural and rhetorical challenges. Transcripts of conferencing sessions revealed how the mediator’s rhetorical and linguistic strategies complemented the author’s disciplinary knowledge to co-construct meaning and the articulation of complex ideas. By comparing the mediator’s solo efforts with the outcomes of collaborative interaction, we demonstrate how their partnership transformed the manuscript into a publishable text. These findings have important practical implications
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
