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
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
Analysis of corporations internal environment on the example of INA d.d.
Get PDFOkolina poduzeća dijeli se na internu i eksternu okolinu. Analiza okoline koristi se za identifikaciju unutarnjih i vanjskih čimbenika koji imaju direktan ili indirektan utjecaj na poduzeće. Interna okolina predstavlja okolinu koja se nalazi u samom poduzeću. Analiza eksterne okoline poduzeća je od ključne važnosti za uspješno poslovanje poduzeća i planiranje poslovne strategije, ali bez provođenja interne analize, odnosno analize koja pojašnjava funkcioniranje unutarnjih elemenata poduzeća, planiranje i provođenje poslovne strategije neće biti potpuno, odnosno svi značajni elementi okruženja poduzeća neće biti uključeni u analizu okoline. Da bi se izradio profil poduzeća, odnosno analizirala njegova interna okolina često se provode funkcijska analiza, analiza resursa te analiza lanca vrijednosti. U ovom radu provest će se analiza interne okoline poduzeća na primjeru naftne kompanije INA d.d. Rezultati istraživanja bit će prikazani pojedinačno pod segmentima funkcijska analiza, analiza resursa te analiza lanaca vrijednosti INA d.d.Corporations environment is divided into internal and external environment. Environmental analysis uses the identification of internal and external factors that have a direct or indirect impact on the corporation. The internal environment is the environment within the corporation itself. Analysis of the external environment of the corporation is crucial for successful business operations and business strategy planning, but without conducting internal analysis, that is, explaining the functioning of internal elements of the corporation, planning and implementation of the business strategy will not be complete, that is, all significant elements of the corporations environment will not be involved in environmental analysis. Functional analysis, resource analysis and value chain analysis are often carried out in order to create a corporations profile or analyze its internal environment. This paper will analyze the internal environment of the corporation on the example of the oil company INA d.d. The research results will be presented individually under the functional analysis, resource analysis and value chain analysis of INA d.d
Fitoterapijski potencijal biljnih anksiolitika i antidepresiva
No full textCilj istraživanja
Cilj je ovoga specijalističkoga rada sveobuhvatan pregled znanstvenih spoznaja o biljnim
anksioliticima i antidepresivima, a posebice usmjeren na kliničke studije. U radu se posebice
ističe sigurnost primjene te precizne analize pravilnoga doziranja, moguće nuspojave te
interakcije.
Materijali i metode
U ovom teorijskom specijalističkom radu napravljena je analiza znanstvene i stručne literature u
području teme rada. U pretraživanju su korištene bibliografske baze podataka PubMed, Medline,
Scopus, Science Direct i Cochrane Library, internetski su izvor stranice Europske agencije za
lijekove EMA (engl., European Medicines Agency) te Europskoga znanstvenoga udruženja za
fitoterapiju ESCOP (engl., Europe Scientific Cooperative on Phytotherapy).
Rezultati
Rezultati mnogobrojnih kliničkih ispitivanja podupiru primjenu gospine trave kod blage do
umjerene depresije. Mnoge kliničke studije opravdavaju primjenu odoljena kao blagoga sedativa
u liječenju nesanice i anksioznosti kada primjena sintetskih lijekova nije opravdana. Smatra se da
djeluje smirujuće i ublažava znakove nervoze kao što su nemir, razdražljivost i napetost zbog
psihičke preopterećenosti, a pri nesanici olakšava uspavljivanje. Pokazalo se da je pasiflora
učinkovita kod generaliziranoga anksioznoga poremećaja, usporedivo s oksazepamom, te da
može smanjiti preoperativnu anksioznost bez izazivanja sedacije ili utjecaja na psihomotorne
funkcije. Zahvaljujući rezultatima kliničkih ispitivanja ukazuje se na potencijal ružičastoga
žednjaka za ublažavanje tegoba blage tjeskobe i blage do umjerene depresije te za poboljšanje
cjelokupnoga raspoloženja u odnosu na konvencionalnu terapiju. Osim navedenoga, postoje i
klinički dokazi da šafran ublažava simptome blage do umjerene anksioznosti i depresije.
Zaključak
Iako klinička istraživanja podupiru primjenu gospine trave, pasiflore, odoljena, ružičastoga
žednjaka i šafrana u suvremenoj fitoterapiji, potrebna su daljnja klinička ispitivanja koja će
pružiti veću razinu dokaza o njihovu terapijskom potencijalu u liječenju anksioznih i depresivnih
poremećaja.Objectives
The aim of this research is a comprehensive review of scientific knowledge on herbal anxiolytics
and antidepressants especially focused on clinical studies. Special attention will be paid to the
safety of application and the correct dosage, possible side effects and interactions will be
addressed.

Cooperative on Phytotherapy (ESCOP) were used as sources of information.
Results
The results of numerous clinical trials support the use of St. John's wort in mild to moderate
depression. Many clinical studies justify the use of resist as a mild sedative in the treatment of
insomnia and anxiety when the use of synthetic drugs is not justified. It is believed to have a
calming effect and alleviate signs of nervousness such as restlessness, irritability and tension due
to mental overload, and in insomnia it facilitates falling asleep. Passionflower has been shown to
be effective in generalized anxiety disorder, comparable to oxazepam, and can reduce
preoperative anxiety without inducing sedation or affecting psychomotor functions. Very
promising results have been obtained indicating the potential of pink thirst to alleviate the
symptoms of mild anxiety and mild to moderate depression and to improve overall mood with
better tolerability than conventional therapy. There is clinical evidence that saffron relieves
symptoms of mild to moderate anxiety and depression.
Conclusion
Although clinical research supports the use of St. John's wort, passionflower, valerian, rhodiola
and saffron in modern phytotherapy, further clinical studies are required to provide a higher level
of evidence of therapeutic potential in the treatment of anxiety disorders
