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
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
Panel: Blockchain applications in government
No full textIn the past fewyears, researchers and practitioners have highlighted the potential of Blockchain (BC) and distributed ledger technology to revolutionize government processes. Blockchain technology enables distributed power and embedded security. As such, Blockchain is regarded as an innovative, general purpose technology, offering new ways of organization in many domains, including e-government for transactions and information exchange. However, due to its very characteristics of peer to peer information exchange, its distributed nature, the still developing technology, the involvement of new actors, roles, etc., the implementation of blockchain applications raise issues that need governance attention. BC initiatives have implications for citizen trust, privacy, inclusion and participation. Governmental organizations need a thorough understanding of the BC design principles, the possible applications in the domain of e-government and the exploration of governance mechanisms to deal with the limitations and challenges of the BC technology when used in a myriad of sectors, ranging from the financial and business sector to the social domains of healthcare and education. In this panel we explore the impact of block chain technology on all levels of government and create an awareness of effects or applications in society that raise governance issues.Information and Communication Technolog
Political Participation in a Digital Age: An Integrated Perspective on the Impacts of the Internet on Voter Turnout
No full textE-government is the use of information technology, especially telecommunications, to enable and improve the efficiency with which government services and information are provided to its constituents. Internet voting is an emerging e-government initiative. It refers to the submission of votes securely and secretly over the Internet. In the United States some areas have already used Internet voting systems for local and state elections.
Many researchers argue that one of the most important social impacts of Internet voting is the effect it could have on voter participation. Numerous studies have called for research on the impact of technology on voter turnout; however, existing literature has yet to develop a comprehensive model of the key factors that influence Internet voting adoption. In light of the gradual implementation of I-voting systems and the need for research on I-voting implications this study combines political science and information systems constructs to present an integrated model of Internet voter participation. The proposed model of Internet voting adoption posits that a combination of technical, political and demographic factors amalgamate to influence the adoption of I-voting services. The study was conducted by surveying 372 citizens ranging in age from 18-75. The findings indicate that an integrated model of I-voting adoption is superior to existing models that explore political science or technology adoption constructs in isolation. Implications of this study for research and practice are presented.Ph. D
