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
Systemy monitorowania ładunków w transporcie intermodalnym
No full textThe article outlined the benefits of using location monitoring systems of intermodal units in rail transport, paying attention to safety. Discusses the technical solutions applied in Poland, as well as other European countries. The statement was made of it equipment and systems offered by the manufacturers. Authors drew attention to the ones that allow to identify the location of the load, monitoring of additional parameters and services arising from the functionality of the solution in question. In addition, the article drew attention to the location monitoring system of the entire vehicles in the train with the operational parameters of the locomotive.W artykule wskazano korzyści wynikające z zastosowania systemów monitorujących położenie jednostek intermodalnych w transporcie kolejowym zwracając uwagę na bezpieczeństwo. Omówiono rozwiązania techniczne stosowane w Polsce, jak również innych krajach europejskich. Dokonano zestawienia urządzeń i systemów informatycznych oferowanych przez producentów zwracając uwagę na te które pozwalają na identyfikację lokalizacji ładunku, monitorowanie dodatkowych parametrów i powiązanie z dodatkowymi usługami wynikającymi z funkcjonalności omawianych rozwiązań. Ponadto w artykule zwrócono uwagę na systemy pozwalające na monitoring położenia całych składów pociągowych wraz z parametrami eksploatacyjnymi lokomotywy
THE IMPACT OF TRAILER CONDITIONS ON THE QUALITY OF REFRIGERATED FOOD TRANSPORT SERVICES – A CASE STUDY
No full textDispelling 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
Model of Container Transport System in Long Distance Freightage – Analysis and Optimalization of Supply Chain
No full textThis article is about the integration idea of rail and road long-distance transport to increase the efficiency of the transport chain. The article compared two transport models - conventional (using road transport) and intermodal transport (using road and rail transport). The proposed intermodal model uses the Container Transport System for freight transport in relation: consolidation point (company) – container terminal – rail transport – container terminal – deconsolidation point and radial transport system of road transport to ensure door-to-door delivery. The model was examined to optimize cost, time, capacity and environmental factors. Moreover, in the article the main features of both models were identified and compared. Freight rates and the prices given in the article are consistent with the actual rates charged by carriers, but they are not an offer
Safety and effectiveness of road cargo transport between Poland and Russia
Get PDFThis article raises the question of the optimal choice based on time, cost and safety, of road cargo routes between Poland and Russia. The analysis includes twelve routes running through Lithuania, Latvia, Belarus and Ukraine depending on the estimated costs and travel time. To choose the optimal route, AHP method was used. The article also addresses the issues of safety and liability of the carrier
