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
Post-Pandemic Impacts of COVID-19 on urban logistics
No full textCOVID-19 challenged the existing trajectory of globalisation based on increased fragmentation of supply chains. COVID-19 altered capitalism’s trajectory in multiple ways. On the one hand, it accelerated the adoption of working from home, resulting in companies introducing a different balance between working in employer premises and home working. On the other hand, COVID-19 accelerated the transition from bricks and mortar retailing to e-commerce with important implications for urban logistics as retailers had to rapidly improvise solutions to alterations in the nature of demand. The chapter explores urban logistics with a focus on pre-COVID trends with much of the analysis exploring vans and local delivery within urban areas. For urban logistics, the challenge is the development of an efficient and flexible system based on minimising costs and air pollutants
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
Institutional challenges to intermodal transport and logistics.
No full textWhile the operational realities of intermodal transport are relatively well known, the institutional challenges are less well understood. This book provides an overview of intermodal transport and logistics including the policy background, emerging industry trends and academic approaches. Establishing the three key features of intermodal transport geography as intermodal terminals, inland logistics and hinterland corridors, Jason Monios takes an institutional approach to understanding the difficulties of successful intermodal transport and logistics. Key areas of investigation include the policy and planning background, the roles of public and private stakeholders and the identification of emerging strategy conflicts.Substantial empirical content situates the theoretical and practical issues in real-world examples via three detailed case study chapters (covering the USA, UK and Europe), making the book useful to students as well as practitioners desiring an understanding of how intermodal transport and logistics work in practice. The identified challenges to intermodal transport and logistics are used to demonstrate how competing port and inland strategies can inhibit the necessary processes of integration required to underpin successful intermodal transport. The book concludes with a look at the future of institutional adaptation that may enhance the capacity of freight actors to engage with intermodal transport developments
Integrating intermodal transport with logistics: a case study of the UK retail sector
Get PDFRetail traffic is one of the main drivers for the growth of intermodal transport services in the UK. The aim of this paper is to understand the key factors underpinning this modal shift in order to learn lessons for other market and geographical contexts. Successful retail intermodal logistics involves many actors, thus this paper is based on semi-structured interviews with major retailers, third-party logistics providers (3PLs) and rail operators, supplemented by document analysis. The qualitative data are analysed via a conceptual framework derived from the literature. Despite past successes and the presence of drivers for future growth, the paper identifies many operational issues without current solutions and the presence of ongoing public subsidy. The major conclusion is that the importance of 3PLs, aggregation and multi-user platforms must be recognised by transport planners in supporting the use of intermodal transport by retailers and other large shippers
