Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe 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
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
Az 57. Közgazdász-vándorgyűlés főbb megállapításai
No full textA fenntarthatóság és a klímaváltozás okozta piaci, nemzetgazdasági és társadalmi kihívások adták a központi témáját az idén 125 éves Magyar Közgazdasági Társaság (MKT) éves konferenciájának. A közgazdász-vándorgyűlés három napja alatt – két plenáris és hét szekcióülés keretében – több mint 130 előadó osztotta meg gondolatait a mintegy 800 fős hallgatósággal.
A rendezvény szerteágazó témái közül a legnagyobb érdeklődést az államháztartás és a bankrendszer fenntarthatósága és az azonnali fizetési rendszer bevezetésének aktualitásai váltották ki; de sok tanulsággal szolgáltak a munkaerőhiányról mint a versenyképességet hátráltató tényezőről; a klímaváltozás agrárágazatban várható hatásairól; az Európai Unió jövőbeli fejlődési irányairól; az innovációról, ezen belül a mesterséges intelligenciáról, a robotizációról; a startupok számára kedvező üzleti környezet feltételeiről; a sport gazdaságtanáról, valamint a színházak fenntartható finanszírozásáról szóló kerekasztal-beszélgetések is.
A Magyar Közgazdasági Társaság Elnöksége a szekcióüléseken elhangzottak alapján öszszeállította az 57. Közgazdász-vándorgyűlés záródokumentumát, és az alábbi megállapításokat, javaslatokat terjeszti elő megfontolásra a magyar gazdaság- és monetáris politika irányítóinak, meghatározó szereplőinek
Variations on the Author
No full text“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

Akutna toksičnost herbicida GAL-57 (bentazon + dikamba) za pacova
No full textAn acute oral toxicity study of the herbicide GAL-57 (Avalon), a mixture of bentazon and
dicamba as active ingredients, was investigated on rats, using a new method that has been
used in the past several years (2001).
Clinical observations symptoms and mortality were performed for all animals in different
time intervals after treatment, and gross necropsy was performed at the end of observation
period.
Clinical symptoms (decreased activity, prone position, abnormal limb position,
decreased righting reflex, decreased grip and limb tone, decreased body and abdominal
tone, dyspnoea) of marked degree were noted after administration of 2000 mg/kg, and animals
were dead in the period of 30-60 minutes after the treatment.
GAL-57 did not cause any clinical sings at single 300 mg/kg bw dose. The physical condition
and behaviour of animals (males and females) were normal, and it is not differ in reaction
to the control.
According to the methodology used in the present study, it could be concluded that
the acute oral LD-50 value of the GAL-57 proved to be between 300 and 2000 mg/kg body
weight in rats, and the product was ranked into Poison group III according to Serbian criteria,
category 4 of the Global Harmonized Classification System, and Category III of the EPA
classification.Akutna oralna toksičnost herbicida (preparata) GAL-57 (Avalon), koji je mešavina dve aktivne
materije, bentazon i dikamba, ispitivana je na pacovima primenom nove metode koja
se koristi tek nekoliko godina (od 2001. godine).
Praćeni su simptomi trovanja i smrtnost životinja u različitim intervalima nakon doziranja,
a po završetku perioda opservacije obavljene su odgovarajuće patohistološke analize.
Kod životinja koje su dobijale preparat GAL-57 u dozi od 2000 mg/kg, registrovana je
pojava veoma izraženih simptoma trovanja kao što su: smanjena aktivnost, nekoordinirano
kretanje, opušten položaj zadnjih nogu (koje vuku pri kretanju), smanjen refleks, smanjen
tonus udova i čitavog tela, dispneja. Simptomi se postepeno intenziviraju, a životinje uginjavaju
u periodu 30-60 minuta posle tretiranja.
Kod životinja koje su dobijale preparat GAL-57 u dozi od 300 mg/kg nije bilo uginjavanja,
niti su registrovane pojave kliničkih simptoma trovanja. Njihova fizička aktivnost i ponašanje
(i kod mužjaka i kod ženki) nisu se značajnije razlikovali u odnosu na kontrolne
životinje.
Po metodologiji korišćenoj u ovim ispitivanjima može se zaključiti da se LD-50 herbicida
GAL-57 kreće između 300 i 2000 mg/kg, pa prema tome preparat može biti razvrstan po
našim kriterijumima u III grupu otrova, u kategoriju 4 po kriterijumima Globalno usaglašenog
sistema klasifikacije (Globally Harmonized Classification System), odnosno u kategoriju
III po klasifikaciji EPA (Environmental Protection Agency)
Dispelling the Myths Behind First-author Citation Counts
No full textWe 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
