Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Antecedents of travellers' eWOM communication
Full text linkDevelopment of the internet and electronic media provide a convenient
platform for travellers to instantly share their experiences. Known as electronic
word-of-mouth (eWOM), it offers a powerful source of information and can also
act as an effective marketing tool. Existing studies have focused on the
conceptualisation and influences of eWOM communication, but limited
attention has been given to the antecedents of it from the attitUdinal
perspective within the tourism industry. This study aims to fulfil that gap.
Data from international travellers having experience of eWOM communication
was collected through online focus groups and survey questionnaire. Content
analysis and structural equation modelling were employed for data analysis
respectively. Based on the literature review and online focus group findings
three key antecedents were identified, being: Adoption of Electronic
Communication Technology, Motivation for eWOM Communication and
Subjective Norm. Thereafter, a conceptual framework was proposed to bring
these three antecedents together for the first time. This was empirically tested,
particularly examining the influences of the overall attitude and behavioural
intention of eWOM communication. Survey results showed that the overall
attitude towards eWOM communication plays an important role in the
understanding of the eWOM communication behaviour of travellers, serving as
a mediator between antecedents and behavioural intention.
From the theoretical perspective, this study fulfils the research gap through
exploring the antecedents of eWOM communication from the attitudinal
perspective. A new conceptual framework is therefore empirically validated
providing the basis for replication within future studies. Through employing the
Technology Acceptance Model, Functional Theory of Attitude, Subjective Norm
and Consumer Attitude, this study contributes to extending those theories in
the context of eWOM communication within the tourism industry. Regarding
managerial implications, this research identifies the antecedents of eWOM
communication behaviour of travellers, which could help practitioners stimu
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
