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
Kibernetska kriminaliteta
Get PDFPurpose:
This paper focuses on investments in protection of organisations against cybercrime. Current research points to enormous financial losses suffered by countries, organisations and individuals due to the impact of criminal offences committed in cyberspace. A detailed overview shows that such losses are fictitious and that the largest share of costs is generated by investments into protection, which, however, is not omnipotent. At the same time, practitioners in the field of cyberspace security find that awareness rising among personnel is a much more efficient and inexpensive method of protection enabling a higher level of security in cyberspace and individual organisations.
Design/Methods/Approach:
The author adapted the cost model of cybercrime by examining data regarding costs and losses inflicted by cybercrime available in different reports and documents drafted by global organisations and governments and analysing the true causes of such losses.
Findings:
The cost model presented in this paper considers the main causes of losses in a comprehensive manner and indicates guidelines for the protection of organisations. However, the provision of greater security in cyberspace is not only a technical, organisational and personnel problem, but ever more often also a political problem, as it is related to the regulation of cyberspace. The costs related to this problem are increasing, since no one endeavours to tackle it.
Practical Implications:
By becoming familiar with the causes and the cost model, organisations may find it easier to decide to invest into protection against attacks from cyberspace and improve their own efficiency with lower costs.
Originality/Value:
This paper presents the impacts of cybercrime on organisations from the point of view of costs and not from the point of view of technical experts in organisations, which are mostly responsible for the implementation of information systems’ protection. Therefore, the analysis of the issue provides management with the possibility to better understand individual problems, thus enabling it to take appropriate positions and support more efficient solutions or methods of protection.Namen prispevka:
Prispevek prikazuje investicije v zaščito organizacij pred kibernetsko kriminaliteto. Aktualne raziskave kažejo oz. predstavljajo enormne finančne izgube držav, organizacij in posameznikov zaradi vpliva kriminalitete v kibernetskem prostoru. Podrobnejši pregled pokaže, da so te izgube fiktivne in da se večina stroškov skriva v investicijah v zaščito, ki pa ni vsemogočna, hkrati pa praktiki varnosti kibernetskega prostora ugotavljajo, da je ozaveščanje osebja učinkovitejša in cenejša zaščita ter ima večji vpliv na varnost kibernetskega prostora in organizacij.
Metode:
Z analizo stroškov in izgub zaradi kibernetske kriminalitete, predstavljenih skozi različna poročila globalnih študij in vladnih dokumentov, ter dejanskih vzrokov za izgube predstavljamo adaptirani stroškovni model kibernetske kriminalitete.
Ugotovitve:
Predstavljeni stroškovni model celovito obravnava glavne vzroke izgub in nakazuje smernice zaščite organizacij. Zagotavljanje višje varnosti kibernetskega prostora pa ni zgolj tehnični, organizacijski in problem osebja, pač pa zaradi regulacije kibernetskega prostora tudi vse bolj politični problem. Ker pa se nihče globalno ne loti reševanja problema, stroški le naraščajo.
Praktična uporabnost:
Organizacije se s poznavanjem vzrokov in stroškovnega modela lažje odločajo za ustrezna vlaganja v zaščito pred napadi iz kibernetskega prostora in izboljšajo lastno učinkovitost z manjšimi stroški.
Izvirnost/pomembnost prispevka:
Zaradi predstavitve vpliva kibernetske kriminalitete na organizacije iz stroškovnega in ne vidika tehnične stroke v organizacijah, ki so večinoma odgovorna za izvedbo zaščite informacijskih sistemov, je razumevanje bližje managementu, s čimer zavzame ustrezna stališča in zaradi boljšega razumevanja podpira učinkovitejše zaščite oz. rešitve

Get PDFNamen diplomskega dela je bil prikaz možnosti, ki jih ponujajo Web 2.0 aplikacije za
podjetja in njihove procese. Gre se namreč za aplikacije nove generacije, katere
omogočajo boljše medsebojno sodelovanje in dostopnost. Kako je te procese možno
izvesti sem tudi prikazal na primeru podjetja PROGMBH, v katerem so takšni procesi
že usklajeni.
Diplomska naloga je sestavljena iz dveh delov. V prvem bolj teoretičnem delu je
opisan sam princip delovanja aplikacij in poslovnih procesov v okolju Web 2.0. V
drugem delu je delovanje in uvedba pojasnjena na podlagi praktičnega primera.
Rešitev je prikazana na podlagi primera. Skupno s tem nam tudi prikazuje vse
možnosti, katere prinaša Web 2.0. Poseben poudarek je dan tudi na Google
aplikacije, katere postavljajo najnovejše standarde za takšen način organiziranja in
izvajanja procesov.The purpose of this undergraduate thesis was to show the possibilities of Web 2.0
applications for businesses and their business processes. Web 2.0 is a new
generation of applications, which allow better interaction and accessibility. How such
processes can be carried out was also presented in the case of the company
PROGMBH in which such processes are aligned.
Thesis consists of two parts. In first more theoretical work is described, the principle
of operation of applications and business processes in an environment of Web 2.0. In
the second part are the operation and the introduction explained on the basis of
practical case.
The solution is shown on a case. This also shows us all the options, which brings
Web 2.0. Special emphasis is also given on the Google applications, which put the
most recent standards of this way of organizing and implementation processes
