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
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
Application of a computer program in the work and time study of timber skidding
No full textProvedeno je istraživanja proizvodnosti skidera na privlačenju drva. Snimanje utrošaka vremena pojedinih radnih zahvata obavljeno je upotrebom dlanovnika s prilagođenim obrascem računalnog programa za provođenje studija rada i vremena. Obradom snimljenih podataka utvrđena je struktura utrošenih vremena. Regresijskom je analizom istražena ovisnosti utroška varijabilnih vremena o glavnim utjecajnim čimbenicima. Konstruiran je model za izračun proizvodnosti u ovisnosti o srednjoj udaljenosti privlačenja. Ukupno je tijekom istraživanja snimljeno 1736,40 minuta utroška vremena. Od toga na efektivno vrijeme otpada 1323,73 minute ili 76,32 %, a na opća vremena 412,67 minuta ili 23,77 % ukupnog vremena. Istraživanjem je utvrđeno da skider Timberjack 350 u uvjetima istraživane sječine, primjenom sortimentne metode, postiže dnevni učinak od svega 20,47 m3 (na udaljenosti privlačenja 250 m) do 24,39 m3 (na udaljenosti privlačenja 100 m)
Research of reasons for not using premium versions of streaming services among generation Z in Croatia
No full textOvaj poslijediplomski specijalistički rad pobliže prikazuje opće obilježja i obilježja generacije Z kao potrošača. Ovo je prva generacija koja je odrasla uz sveprisutnost širokopojasnog interneta i to ne samo na računalima već i na mobilnim telefonima. Samim time su naviknuti brzo dolaziti do svih informacija koje ih zanimaju, u svega nekoliko sekundi. Razvoj interneta i tehnologije, kao osnova digitalne revolucije, omogućio je da se mnoge navike promjene iz korijena. Jedne od njih su i način na koji se konzumiraju video i glazbeni sadržaji. Zahvaljujući “streaming” tehnologiji filmovi, serije i glazba postali su povoljniji no ikad i dostupni na zahtjev – u bilo koje vrijeme, na bilo kojem mjestu i na bilo kojem uređaju. Iako su te karakteristike upravo ono što generacija Z želi od proizvoda i usluga, ne koriste svi pripadnici ove generacije premium (plaćene) verzije streaming usluga. Istraživanje u sklopu ovog rada, provedeno na uzorku od gotovo 500 pripadnika generacije Z, daje uvid u korištenje plaćenih streaming usluga među mladima u Hrvatskoj i najčešće razloge zbog kojih iste ne koriste. Istraživanjem se dolazi do spoznaje kako je većina mladih svjesna postojanja streaming usluga kao i da su zadovoljstvo besplatnim verzijama i cijena premium streaming usluga glavni razlog zbog kojeg se ne odlučuju na premium verziju. S druge strane, postoje indikacije kako bi povećanje dohotka određeni dio generacije Z moglo potaknuti da odluče plaćati za korištenje streaming usluga.This post-graduate specialist thesis describes the general characteristics and characteristics of generation Z as consumers. This is the first generation that grew up with the ubiquity of broadband internet, not only on their computers but also on mobile phones. They are used to quickly access all the information they are interested in, in just a few seconds. The development of the Internet and technology, as the backbone of the digital revolution, has made it possible to drasticcaly change many habits. One of them is the way people consume video and music content. Thanks to streaming technology, movies, shows, and music have become more affordable than ever. And available on demand - at any time, in any place and on any device. Although these characteristics are exactly what Generation Z wants from products and services, not all members of this generation use premium (paid) versions of streaming services. The research which is part of this work, conducted on a sample of almost 500 members of generation Z, provides an insight into the use of paid streaming services among young people in Croatia and the most common reasons why they do not use them. The research leads to the conclusion that most young people are aware of the existence of streaming services and that satisfaction with free versions and the price of premium streaming services are the main reason why they do not decide to pay premium version. On the other hand, there are indications that the increase in personal income could encourage a certain part of Generation Z to to pay for premium streaming services
