Get PDFGoing 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
E-Commerce and Social Media Use in Cambodia
No full textWe adopt Media system dependency theory (MSD) to examine e-commerce and social media use in Cambodia. A field study was conducted by performing semi-structured interviews with three major e-commerce website owners: Little Fashion, Khmer24.com, and Comptech.com. Through the lens of MSD, we observe how these e-commerce websites were established by using a grass-root approach. Furthermore, we interview local business owners who are using social media—Facebook and YouTube—as tools of marketing and customer services. We found that 1) e-commerce activities are fully depends on social media and that 2) from a media perspective Facebook plays the role of fulfilling user’s needs of getting information and services and that 3) e-commerce activities are highly depend on big players such as Facebook and Google. We also found that the environment is yet mature for e-commerce activities but opportunities exist for business ventures. The social background of Cambodia is unique, as such, the online activities and social media use behavior is completely different from what is observed in western countries and we conclude few unintended consequences of social media use which go beyond the scope of our knowledge
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
eService Customer Retention: An Affective Events Theory Perspective
Get PDFCurrently, one stream of online customer behaviors research focused on the quality of the systems in determining systems success, whereas another stream of research focused on the effects of online incidents including online waiting interruptions and service failures on consumer behaviors. The study attempts to bridge the two streams of research and to explain e-service customer post-adoption behaviors in a unified model from the perspectives of affective events theory. Findings support the proposed model positing that e-service customer retention behaviors were determined by perceived site quality and cognitive appraisal of incidents handling. Post-adoption behaviors investigated in the study include continuance intention, complaint intention, and recommendation intention. Practical implications were also suggested
eService Customer Retention: The Roles of Negative Affectivity and Perceived Switching Costs
Get PDFThis paper examines the relationships between key drivers of e-service customer’s intention to continue to use an eservice. From expectancy confirmation theory (ECT) in consumer behavior literature and technology acceptance model (TAM) in IS, we hypothesize that e-service customers’ intention to continue to use an e-services is determined by the degree of customer satisfaction with e-service use and perceived usefulness of e-service. We also attempt to illustrate that perceived switching costs moderate the effect of perceived usefulness and satisfaction on continuance intention. Furthermore, negative affectivity, a dispositional affective stable broad trait measure, is hypothesized to affect the level of customer satisfaction with an e-service. Understanding the effect of customer predisposition on satisfaction and the effect of perceived switching costs allows practitioners and researchers in IS to have better knowledge of e-service discontinuance behavior
