Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
Application of Special Risk Reduction Protective Measures in Combiterminals for Dangerous Goods.
During the combined transport of dangerous goods, in the territory of combiterminals, transport takes place from one type of transport to another means of transport. During the trans-shipment and the temporary storage of hazardous materials accidents resulting in smaller or larger consequences may occur (and in recent times have occurred as well). Experience has shown that reducing the consequences of such accidents requires the use of some special tools. In our article we present these tools in order to reduce such consequences as well as the technical foundations of their applicability.During the combined transport of dangerous goods, in the territory of combiterminals, transport takes place from one type of transport to another means of transport.

Dispelling the Myths Behind First-author Citation Counts
We 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
Szénhidrogén-gázkeveréket küldeménydarabban szállító közúti jármű biztonsági kockázatának értékelése = Security Risk Assessment of a Road Vehicle Carrying a Hydrocarbon Gas Mixture in a Package
Transport of dangerous goods is committed to strict, international regulations. The strict regulation of transport of dangerous goods by road has a high importance, since by releasing hazardous materials during a road accident could create a potentially large area of risk. On the other hand, the dangerous shipment passing through inhabited areas can be a potential target of a terrorist attack by utilising the properties of dangerous goods. There are specific provisions in the dangerous goods transport regulations to reduce this type of risk, but these measures may need to be adapted to the specificities of the narrower economic, social and safety context. In this publication, the authors examine the consequences of an intentional act against a packaged shipment of propane-butane gas exempted from security provisions, by using software risk analysis. A veszélyesáru-szállítás szigorú, nemzetközi szabályokhoz kötött. A veszélyes áru közúti szállításának szigorú szabályozása több szempontból is kiemelt jelentőségű, mivel egy esetleges közúti baleset során a veszélyes anyag szabadba kerülésével jelentős méretű veszélyeztetett terület alakulhat ki. Másrészt a veszélyes áru tulajdonságait kihasználva, a lakott területeken áthaladó veszélyesáru-szállítmány potenciális célpontja lehet egy esetleges terrorcselekménynek. Az ilyen típusú kockázat csökkentésére a veszélyesáru-szállítási szabályzatokban külön rendelkezések vonatkoznak, azonban előfordulhat, hogy ezeket az intézkedéseket a szűkebb gazdasági, társadalmi és biztonsági környezet sajátosságaihoz érdemes igazítani. A publikációban a szerzők küldeménydarabban való szállítás esetén a visszaélés elleni rendelkezések hatálya alól mentesülő, propán-bután gázszállítmány elleni szándékos cselekmény következményeit vizsgálják meg szoftveres kockázatelemzés segítségével.
