The impact of double-hull requirements on the inland navigation market of dangerous goods
No full textInnovation in inland navigation : failure and success: the European case
No full textAbstract: European inland navigation is generally regarded to be part of the solution to road congestion. It is also the transport mode with the lowest external costs. Therefore, a strong and competitive inland navigation can be a key element in achieving climate change objectives for the transport sector. In order to remain competitive and attractive, inland navigation needs to innovate in the midst of a rapidly changing globalized logistics chain. Innovation in inland navigation is both necessary to maintain the modal share or to grow in performance, and to keep the title of the most sustainable transport mode. Alternative fuels, innovative engines and propulsion, ship design, automation and digital business applications are just a few examples of possible innovations that could provide an answer that is attractive both for the investor (industrial-economic perspective) and for society (welfare-economic perspective). Private actors play a role in this; innovation is often a story of collaboration between public and private actors within a multi-layered network to create the best conditions for successful innovation. This doctoral dissertation focuses on innovation in European inland navigation and takes the reader on a journey into a relatively unchartered world without avoiding relatively complex networks such as the (pan-)European institutional setting. The central research question is as follows: What are the factors that determine success or failure of innovation in inland navigation and what is the role of policy? Four cases have been analysed in order to answer the research question. The cases concern the automated inland vessel, LNG as an alternative fuel for inland navigation, e-barge chartering instead of conventional chartering and the small barge convoy to reactivate small waterways. After a detailed and updated institutional analysis of the European multi-level governance model for inland navigation policy, a combination of analytical methods is applied where meaningful and possible within a multiple case study framework. The system innovation approach allows for mostly qualitative analysis and shows if there are any patterns during the development phases of innovation and which conditions lead the innovation to success or failure. The (social) cost-benefit analysis framework was the main source of inspiration to develop a quantitative economic analysis that includes external costs and that fits the private cost structure of an inland vessel. Innovation can bring benefits for both private and public actors or for only one of them and has implications for both actors. Finally, the role of the various policy levels, tools and their impact are analysed. This study helps investors to decide if innovation is attractive and allows policy makers to judge whether and how innovation can be supported or not and by which policy level(s)

No full textGoing 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
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
