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
Improving decisions support for operational disruption management in freight transport
No full textIn this study, the operational management of disruptions is investigated in transport chains with a focus on phases after disruptions have occurred. Instead of focusing on strategies mitigating risk before disruption occurs this paper considers the recovery phase of a disruption at operational level. The purpose of this paper is to provide insights for operational disruption management to achieve improved decision support for the recovery phase. A qualitative method of a case study is used in this paper for the transport around a distribution centre at a FMCG company in Sweden with data collected from semi-structured interviews and observations. The analysis of the findings proposes different types of detection in the recovery phase, which give insights for how to perform early recovery actions. The study contributes to disruption management in transport chains through insights on how to achieve early recovery actions by combining the different detection types with the phases of prediction and action. Instead of focusing on strategies mitigating risk before disruption occurs this paper considers the recovery phase of a disruption at operational level. This is shown to be important to understand reactive or proactive actions in the recovery phase. Transport managers can use the proposed detection types in this paper to detect disruptions in order to respond to disruptions earlier instead of developing competences of fire-fighting for occurred impacts
Real-time information for operational disruption management in hinterland road transport
No full textPort hinterland transport literature has previously taken mainly a port perspective of operational disruption, for example delays or congestion, and as such lacks understanding of how real-time information can contribute to management of operational disruption outside the port. Therefore, the purpose of the paper is to explore real-time information for operational disruption management in road hinterland transport. A qualitative single case study approach is adopted at a logistics service provider responsible for road hinterland transport. The findings show improvement potential in disruption management by applying real-time information. Mainly issues related to the detection of disruption are highlighted to generate insufficiencies for the operational disruption management. Furthermore, the focus of real-time information for the impact on goods flow, rather than disruptions in the surrounding environment of transport operations, was found to limit disruption management. The paper intends to contribute to the hinterland transport literature by broadening the understanding for management of operational disruption through use of real-time information
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
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
