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
Reducing global warming impact for Kjøkøysund based on alternative bridge designs
No full textConcrete manufacturing account for almost one tenth of the global CO2- emissions. A big portion of the concrete greenhouse gas emission comes from the production of cement, still concrete is the most used construction material in the world. New types of concrete have been and are under development in order to reduce their global warming impact. One of the new concrete types is low carbon concretes. These types of concrete have been utilized widely in the building industry but is absent in larger bridge constructions.
The main goal for this thesis is to investigate the possibilities for material and design change of Kjøkøysund bridge, with the goal to reduce the global warming impact. Kjøkøysund bridge is a concrete cantilever bridge, which connects Kråkerøy and Kjøkøy. There has been done a condition assessment on the bridge, and the conclusion of this work is to tear the existing bridge and construct a new one next to it. The report from Statens Vegvesen “Bærekraftige betongkonstruksjoner” has been used to investigate the possibilities to optimize and reduce the greenhouse gas emissions for concrete bridges. Some of the possible solutions in the report is to change materials or superstructure design.
In this thesis the research question has been approached by conducting a literature study. The gathered information has been employed on the case study ‘’ Material and design change on Kjøkøysund bridge’’. Various designs with different materials and superstructures have been investigated for an alternative solution for Kjøkøysund bridge. EPD from different concrete and steel supplier have been collected and used in a calculation to find most environmentally friendly material. For the transportation stage A4, the transport calculator provided by Østfoldforskning have been used. To verify these results a life cycle assessment with the software One Click LCA have been conducted, with several other bridge designs which was considered to be suitable for Kjøkøysund bridge.
Regarding global warming impact for Kjøkøysund bridge, alternative bridge solutions have been presented in this thesis. Since this thesis have a broad approach and not focused on one specific solutions, further research must be conducted
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
