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
Učinkovitost programa "Spodbujajmo nekajenje" pri prvi generaciji slovenskih osnovnošolcev
No full textIzhodišča: Namen raziskave je oceniti učinkovitost programa \u27Spodbujajmo nekajenje\u27 v slovenskih osnovnih šolah s prikazom učinkov programa na znanje in stališča o tobaku ter kadilske navade mladostnikov. Metode: Primerjali smo znanje in stališča o tobaku in njegovi škodljivosti za zdravje ter različne vidike kadilskega vedenja med osnovnošolci, ki so bili deležni šestletnega programa spodbujanja nekajenja, in osnovnošolci, ki v tovrsten program niso bili vključeni. V raziskavi je bilo s pomočjo vprašalnika anketiranih 1.055 učencev v starosti 14 do 16 let iz 20 osnovnih šol iz različnih predelov Slovenije, od tega 560 iz osnovnih šol, kjer izvajajo program, in 495 iz osnovnih šol, kjer programa niso izvajali. Raziskava je bila izvedena v obdobju maj do junij 2006. Rezultati: V naši raziskavi smo zabeležili ugodne učinke programa na znanje, stališča in kadilsko vedenje osnovnošolcev. Programje pomembno povečal celokupno raven znanja pri mladostnikih obeh spolov, pomembno vplival na stališča pri dekletih pri fantih in na delež tistih, ki niso kadili. Pomembnih razlik v drugih vidikih kadilskega vedenja nismo zabeležili. Zaključki: Programi preprečevanja kajenja v šolah so eden odučinkovitih ukrepov za zmanjševanje rabe tobaka med mladimi. Program \u27Spodbujajmo nekajenje\u27 izkazuje ugodne učinke na znanje, stališča in kadilske navade osnovnošolcev. Rezultati naše raziskave in podatki iz tuje strokovne literature podpirajo nadaljevanje izvajanja pa tudi prenovo oziroma dopolnitve programa \u27Spodbujajmo nekajenje\u27.Aim: The aim of the study was to estimate effectiveness of the primary school-based programme \u27Let\u27s Promote Nonsmoking\u27 with describing its effects on knowledge and attitudes about tobacco and also smoking behaviour ofyouth. Methods: We compared knowledge and attitudes about tobacco and health consequences of tobacco use and also different measures of smoking behaviour between primary school pupils, who were participating in nonsmoking promotion programme of six years duration and primary school pupils, who were not participating in the programme. In our study we used a questionnaire and surveyed 1.055 pupils aged 14 to 16 from 20 primary schools from different parts of Slovenia, 560 were from primary schools in which the programme was implemented and 495 from primary schools without the programme. The study was carried out during the period from May to June 2006. Results: We demonstrated positive effects of the programme on knowledge, attitudes and smoking behaviour of primary school pupils. The programe sigificantly increased the overall knowledge in youth of both genders, significantly increased attitudes against tobacco in girls and share of never smokers in boys. We have not demonstrated significant changes in other measures of youth smoking behaviour. Conclusions: School-based smoking prevention programmes are one of the effective measures for decreasing tobacco use among youth. Programme \u27Let\u27s Promote Nonsmoking\u27 also demonstrates positive effects on knowledge, attitudes and smoking behaviour of primary school pupils. Results of our study and data from foreign scientific literature support continued implementation and also renovation and updating of the programme \u27Let\u27s Promote Nonsmoking\u27
