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
Comparison of agile and predictive project management
No full textDinamični razvoj tehnologije i sve veća kompleksnost projektnih zahtjeva klijenata potaknula je organizacije na uporabu različitih metoda upravljanja projektima kako bi se što učinkovitije izveli. U ovom će se radu analizirati dva ključna pristupa upravljanja projektima: tradicionalni, to jest prediktivni (engl. predictive/waterfall) i moderniji agilni/adaptivni (engl. adaptive/agile) pristup. Obje metode nude različite načine pristupa upravljanja projektima, od načina komunikacije s klijentima, samog načina izvođenja pojedinih faza i procesa unutar zadanog projekta, ali i kako veličina projekta i zahtjevi klijenta utječu na odabir metode upravljanja. Kao što ne postoje dva ista klijenta, tako ne postoje ni dva jednaka projekta. Može biti određenih sličnosti, ali svaki klijent, ili u ovom slučaju projekt, ima specifične zahtjeve koji se trebaju izvršiti. Ovaj će rad istražiti kako i za koje se vrste projekata primjenjuju prediktivna ili agilna metoda, koje su njihove prednosti i nedostatci, specifični izazovi koji se pojavljuju kod svake od metoda te kako se s njima nositi. Nakon pregleda i obradbe dostupne literature o upravljanju projektima provest će se intervju s ključnim zaposlenicima iz triju hrvatskih tvrtki koji će iznijeti svoja iskustva u radu na projektima upravljanim prediktivnom i agilnom metodom. Uzimajući u obzir iskustva ispitanika i znanje stečeno kroz analizu dostupne literature, kreirat će se praktične smjernice koje organizacijama mogu pomoći u donošenju odluka kod odabira metode upravljanja projektima kako bi se umanjio rizik odabira metode koja nije prikladna za zadani projekt.Dynamic development in technology and the increasing complexity of the client's project requirements encouraged organizations to use different methods of project management in order to complete them as efficiently as possible. This paper will analyze two key approaches – traditional, i.e. predictive/waterfall approach and more modern agile/adaptive approach. Both methods offer different ways of approaching project management, from communication with clients, the execution of individual phases and processes within the given project, to how the size of the project and client requirements influence the choice of management method. Just as there are no two identical clients, there are no two identical projects. There may be certain similarities, but each client, or in this case project, has specific requirements that need to be fulfilled. This paper will explore how and for which types of projects predictive or agile methods are applied, what their advantages and disadvantages are, specific challenges that arise with both methods and how to deal with them. After reviewing and processing the available literature on project management, interviews with key employees from three Croatian companies, who will share their experiences working on projects managed by predictive and agile methods, will be conducted. Taking into account the experiences of the interviewees and analyzing the knowledge gained through the available literature, guidelines will be developed for choosing the ''right“ management method to minimize the possibility of selecting a method that is not suitable for the given project
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
The development of e-commerce and its increase in Croatia during the COVID-19 pandemi
No full textU radu je prikazan povijesni proces razvoja e-trgovine od njenih početaka do danas, njezini početci te kako se e-trgovina postepeno razvijala uz različite tehnologije koje su postajale dostupne. Također su opisane njezine prednosti, od dostupnosti bilo gdje na svijetu pa do same jednostavnosti i brzine kupnje u bilo kojem trenutku i velikog izbora različitih proizvoda kojima kupci mogu uspoređivati specifikacije i cijene jednim klikom miša. Nadalje, opisani su i nedostaci poput nepovjerenja kupaca u sigurnost e-kupovine zbog davanja osobnih podataka, loše logistike poduzeća koje utječe na vrijeme dostave ili čak dostavljanje željenih proizvoda u odnosu na klasični način odvijanja trgovine licem u lice i trenutnog pregleda i kupovine proizvoda. Rad osim pregleda znanstvene i stručne literature na navedenu temu obuhvaća i analizu studija slučaja jednog od najvećih trgovačkih divova Amazona i njegovih karakteristika. Osim toga, vlastitim istraživanjem u vidu ankete, istražene su i promjene navika hrvatskih potrošača kod korištenja usluga e-trgovine u vrijeme COVID-19 pandemije koja je uvelike utjecala na opseg e-trgovine. U zaključku je sumiran čitav rad, što se s njime nastojalo pokazati od razvoja e-trgovine, uspjeh Amazona u COVID-19 pandemiji te osvrt na vlastito istraživanje u vidu ankete gdje je s obzirom na analizu literature pokazano kako je ipak manje od polovice ispitanika počelo više koristiti e-trgovine od početka pandemije, ali sukladno literaturi, jedan od najvećih problema je bila nemogućnost fizičkog pregleda proizvoda koji se kupuj

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
