Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Full text linkWe 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
Experimental verification of concrete members strengthened with UHPC
No full textTato práce se zabývá experimentálním ověřením betonových prvků zesílených pomocí UHPC. V úvodních kapitolách jsou uvedeny základní informace o ultra-vysokohodnotných betonech, o jejich použití pro zesilování konstrukcí a o problematice soudržnosti UHPC a podkladního betonu. Hlavní část práce je rozdělena do několika dílčích částí. První část se zabývá přípravou, provedením a vyhodnocením ohybových zkoušek betonových prvků, které byly zesíleny vrstvou UHPC. V další části práce bylo provedeno experimentální ověření kontaktu UHPC a podkladního betonu. Závěrečná část práce se zabývá návrhem průběhu zkoušky na protlačení. Výsledky zkoušek potvrdili předpoklad, že při vhodné povrchové úpravě podkladního betonu, lze dosáhnout spolupůsobení obou materiálů bez použití spřahovacích prvků.This thesis deals with the experimental verification of concrete members strenghtened with UHPC. Basic information about Ultra-High- Performance Concrete are given in the introduction. One of the main purpose is to define the bond between UHPC overlay and and the existing concrete structure. The main part of the thesis is divided into several sub-parts. The first part deals with the preparation, execution and evaluation of bending tests of concrete elements strengthened by an UHPC overlay. In the next part of the thesis an experimental verification of contact between UHPC and concrete was carried out. The final part of the thesis deals with the design of punching shear test. The test results confirmed that, when the surface finishes of the concrete substrate surface are appropriate, the interaction of both materials can be achieved without the use of connectors

The experimental dynamic analysis of an existing footbridge
No full textTato práce se zabývá experimentální dynamickou analýzou lávek pro pěší. Úvodní kapitola shrnuje teoretické základy dynamiky stavebních konstrukcí. Následující kapitoly jsou zaměřeny na experimentální dynamiku stavebních konstrukcí. Jsou zde popsány druhy dynamických zkoušek, přístroje pro měření a analýzu. Další kapitola je zaměřena na posouzení dynamické odezvy lávek. Hlavní část práce se zabývá stávající lávkou pro pěší přes Berounku v Dobřichovicích u Prahy, na které byla provedena dynamická zkouška zaměřená na stanovení charakteristik vlastního kmitání a zejména dynamické odezvy na zatížení chodci. Vyhodnocené výsledky byly posouzeny podle současných norem stanovující kritéria komfortu chodců. Z tohoto hlediska lávka při běžném provozu vyhověla.This thesis deals with the experimental dynamic analysis of footbridges. The opening chapter summarizes the theoretical basis of the structural dynamics. The following chapters are focused on the experimental structural dynamics. There are described the types of dynamic tests, devices for measurement and vibration. Another chapter is focused on the assessment of the dynamic response of the footbridges. The main part of the thesis deals with the existing footbridge across Berounka river in Dobřichovice near Prague, where a dynamic test was carried out aiming at the determination of modal characteristics and especially the dynamic response to pedestrian load. The evaluated results were assessed according to current standards setting the comfort criteria. From this aspect, the footbridge in normal operation has met the criteria
