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
Human factor and preventing accidents at sea
No full textTijekom posljednjeg desetljeća broj pomorskih nesreća je u padu. Ipak, kako se
brodovi za prijevoz tereta i ljudi povećavaju, čak i jedna nesreća kao što je izlijevanje nafte
iz supertankera, može imati katastrofalne i dugoročne posljedice na morski ekosustav, okoliš
i ekonomiju.
Pomorske nesreće su složene i izazvane kombinacijom događaja i postupaka koje na
kraju rezultiraju gubitkom ljudskih života, nepovratnom ekološkom, okolišnom i
ekonomskom štetom.
U ovom radu govorit će se o važnim čimbenicima kojima se može spriječiti nastajanje
nesreća na moru. Pravilnom organizacijom rada, pravilnim upravljanjem posadom,
ulaganjem u izobrazbu pomoraca, pravodobnom reakcijom i prevencijom nezdravih navika
može se spriječiti gubitak ljudskih života, imovine, onečišćenje okoliša i uništavanje biljnog
i životinjskog svijeta.
Na kraju rada opisat će se uzroci ekološke katastrofe koju je izazvao brod „Exxon
Valdez“ te posljedice na okoliš i ekonomiju koje se osjete i danas.Over the last decade, the number of maritime accidents has fallen. However, as
vessels continue to increase in size, one single incident, such as oil spills from tankers, can
have catastrophic and long-term consequences for marine ecosystem, the environment and
economies.
II
Maritime accidents are complex and caused by a combination of events or proccesses
that might result in the loss of life, and irreversible ecological, environmental and economic
damage.
This paper will discuss important factors that can prevent maritime accidents. Proper
work organisation, proper crew management, invesment in seafarer 's training, timely
response and prevention of unhealthy habits can prevent the loss of human life, property,
environmental pollution and the destruction of flora and fauna.
At the end of the paper, the causes of the environmental disaster caused by the ship
„Exxon Valdez“ will be described, as well as the consequences on the environment and
economy that are still felt today

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
