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
Understanding the role of social media in relation to alternative food networks: a case of Chester and its region
Get PDFAlternative Food Networks (AFNs) are a system of food provision which is considered as the embodiment of the Sustainable Development (SD) agenda. They typically operate counteractively to conventional food networks (CFNs) seeking to reconnect all members in the supply chain through ethical and sustainable engagements. They are grounded by the theoretical underpinnings of quality conventions (Murdoch, 2000; Thévenot, 2002) and embeddedness notions such as alterity, valorisation, and appropriation (Dansero & Puttilli, 2014; Kirwan, 2004).
Many scholars have focused on exploring AFNs in various contexts, initially focusing on binary notions of dichotomy between AFNs and CFNs, then developing discourse in terms of assessing hybridity (Holloway et al., 2006; Maye, 2013; Ponte, 2016; Renting, Marsden, & Banks, 2003; Tregear, 2011). Recent studies have indicated the potential for further research concerning social media based AFNs (Bos & Owen, 2016; Reed & Keech, 2017; Wills & Arundel, 2017). Therefore a contribution in terms of further understanding this issue arises from this thesis.
The research was conducted in the midst of the referendum for the UK to withdraw from the European Union, the subsequent ‘leave’ vote resulting in a level of uncertainty in terms of policy implications. One policy implication may be that the UK will have to readdress the way it engages and supports its food and agriculture sector post-Common Agricultural Policy, therefore this research comes at a timely juncture.
This research adopts an interpretivistic epistemological stance, with a constructivist ontological position. Social network analysis (SNA) of Twitter connections was conducted in order to assess connectivity and density of the AFN that was present in Chester and its region. Content analysis of this network was then conducted in order to understand SD related terms and shortlist pertinent actors for further analysis. Interviews were conducted with nine actors from this network in order to critically evaluate their perceptions of SD from an online and offline perspective.
The results of the SNA suggest that the AFN of Chester and its region was not particularly well connected in terms of density. However, the SNA was a useful data collection tool, especially concerning the replicability and transferability of participant selection strategy.
Further results suggested that there was a need for more organisational structures to support AFNs in becoming more mainstream and collaborative. It was also clear that there was still a degree of opposition between CFNs and AFNs, despite hybridity. A final finding of the research is the consideration of smart localism.
The implications of this research are discussed, along with suggestions for future research including; the need to better understand leadership, relations between AFNs and CFNs, the role played by intermediates, and the expansion of social media based research.University of Chester Gladstone Fellowshi
Efficient agriculture: Sustainable organic olive oil production in Almería Province; smallholder perspectives
Get PDFThe survival of smallholder olive-oil producers is a growing concern for the European Union. Despite subsidies (such as single farm payment), competition from intensive producers and increasing operating costs results in abandonment or a change to intensification which has long term negative environmental impacts. This dissertation explores ways to provide useful information to aid smallholder survival in Almería Province. Through interviews with smallholder producers, a review of relevant literature, and a case study of best practices in sustainable olive-oil production from Oro del Desierto, this research produced a useful finding; organic production is economically viable in the long term therefore is a potential adaptation option for survival over intensification of production. If smallholder growers produce high-quality extra virgin organic olive-oil, and employ effective marketing strategies and sustainable practices, their methods can be economically viable as they sell to a growing niche market. Additionally, organic production offers many environmental benefits such as increasing biodiversity
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
