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
The Social Intranet : Insights on Managing and Sharing Knowledge Internally
No full textThe report highlights four different social networking sites (think: Government’s own internal Facebook) that are designed to increase collaboration and knowledge sharing opportunities among public servants. The insights are based on qualitative interviews I conducted with public managers who were in charge of designing the social Intranet sites and a review of the existing press coverage and academic literature on enterprise social technologies.publishedpublishe
Digitale Verwaltung umsetzen
No full textBisher orientieren sich Digitalisierungsbemühungen in der öffentlichen Verwaltung vor allem an den Fachverantwortlichkeiten und Fachprozessen, die in oftmals isoliert operierenden Ressorts organisiert sind. Ein erster Schritt in Richtung Orientierung der Dienstleistungen an den Bedürfnissen der Bürger wurde mit dem OZG angestoßen. Fachverantwortliche müssen sich nun an den Lebenslagen der Bürger orientieren. Auf der Basis von Experteninterviews wurden fünf Schritte abgeleitet, die dabei helfen, digitale Transformationsprojekte umzusetzen (siehe Abbildung).publishe
Digital service teams in government
No full textNational governments are setting up digital service teams (DST) – IT units outside the centralized CIO's office – to respond to complex governmental and societal challenges in a responsive and agile manner. DSTs emerge as a third space between centralized and decentralized IT departments that are triggered by large-scale IT failures and the need to abandon black swan IT projects - tasks that traditional CIO offices were not able to handle so far. DSTs design principles have been replicated from the initial idea of the UK's Government Digital Service team and implemented in other countries, such as the U.S., Canada, Italy, or Finland. For this article, a qualitative interpretative approach was chosen to understand external and internal context factors that contribute to the emergence of these digital service teams. The article brings initial clarity of the composition and tasks of DSTs and extends the existing theory of context by providing insights about this third space between centralized and decentralized IT departments to organize IT Governance in public sector organizations.publishe
Supporting Policies, Regulations and Milestones for Government 2.0 in the United States of America : Report prepared for the European Commission tender
No full textGovernment 2.0 the United States has evolved out of political, regulatory and ‘acceptable use’ changes, but also an increased level of maturity of social media tools. To highlight just the most prominent tools: LinkedIn, Friendster, and MySpace were launched in 2003, followed by Facebook in 2004, YouTube in 2005, and Twitter in 2006. We can add to this development the emergence of a whole conglomerate of other Web 2.0 tools, such as wikis, blogs or virtual worlds. This paper explores the supporting policies, regulations and milestones that have lead to Government 2.0 implementation in the United States of America.publishe
