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
Regulation of complex adaptive digital systems: optimizing competition and consumer welfare outcomes in Nigeria's converging telecommunications market
Get PDFThe thesis explores how emerging digital ecosystems would benefit from new regulatory approaches that differ from the traditional models applied in the telecommunications sector. The historical model is typically based on an analysis of static efficiency, which does not appropriately acknowledge the often complementary nature of the evolving digital ecosystem and its dynamic efficiencies. Informed by the increasing complexities of the converging telecommunications ecosystem, the corroboration of this core proposition required the examination of not just the technical but also the socio-economic and institutional elements of advanced communication systems. Findings from existing academic literature on pro-competition regulatory challenges of digital markets focus more on mature competitive markets in the Global North. There is a paucity of empirical studies on the predominantly pre-paid mobile markets of the South — where competition laws and institutional arrangements that facilitate market competition are still nascent. More so, extant studies of telecommunications market regulation were mostly supply-side focused, not taking into full consideration demand-side elements, especially the social and public value of the converged telecommunications ecosystem. In addition, most of the studies focused on quantitative methodologies largely based on econometric analysis. To fill a gap in the research literature, the thesis explores these issues within the context of a developing country, Nigeria. The research responds to the dearth of critical policy enquiry within the domain of applied social policy research that relies on qualitative interrogation to examine the interrelated ecosystem elements and arrive at answers to questions that generally cannot be understood through quantitative methods. Although there is a rich vein of literature regarding telecommunications market regulation, explaining network competition principles and the institutional conditions under which they thrive, instances of such research in a developing country context are few and far between. The thesis bridges these gaps by applying a systemic approach based on complexity theory and institutional analyses drawing on the institutional analysis and development (IAD) framework to answer regulatory questions of competition policy under conditions of constraint, such as in emerging markets. By developing a conceptual framework drawing on these two approaches, the effects of demand-side access and willingness to pay are assessed via an in-depth qualitative analysis to examine the resulting dynamic impact on social welfare. The thesis provides a case study of Nigeria to examine these issues in a developing country context. The research questions examine the complexities of regulating dynamic markets to achieve often competing objectives of competition, investment, innovation, and consumer welfare. The author deployed the conceptual framework to analyze the evidence for the case rather than for purposes of theoretical contestation or theory building. Therefore, the thesis methodology leans towards an inductive research paradigm within the episteme of interpretive constructivism. The author adopted a qualitative methodology for the study based on the nature of the research questions and the conceptual framework. However, empirical insights were generated by the author from a combination of methods. The research process comprised a country-specific causeeffect analysis of the regulatory challenges of OTT-MNO competition in the context of Nigeria's converging telecommunications industry and its imperatives for both innovation and investment policy outcomes. Incorporating in the methodology a process tracing mechanism allowed for the elucidation of critical junctures in the structural evolution of the country's telecommunications market and the path-dependent outcomes for alternative policy options. Consequently, the author undertook an initial step in mapping the converging Nigerian telecommunications ecosystem, which detailed its complex interrelationships in relation to ecosystem stakeholders and institutions, regulatory governance mechanisms, and outcomes to complement the qualitative analysis. The ecosystem mapping was then used to identify critical opportunity pathways for regulatory evolution both in the 3 short and long terms for effectively addressing the competition dynamics related to OTTs and MNOs within the converging Nigerian telecommunications market. The thesis contributes to the existing body of knowledge on regulating complex adaptive systems by exploring competition and consumer welfare optimization in Nigeria's converging telecommunications market. It does so by building on the literature on socio-technical systems' governance and policy design within adaptive external environments, deploying key concepts from complex adaptive systems theory. In extending and problematizing the domain discourse, a key regulatory challenge that crystallizes in assessing the converging Nigerian market is an appropriate regulatory structure that optimizes investment and innovation incentives on both sides of the market — infrastructure development and next-generation services provisioning. In addressing this regulatory challenge under conditions of institutional and resource constraint, the thesis considers the preconditions, necessary and sufficient institutional arrangements for effective competition regulation within Nigeria's converging telecommunications sector to maximize dynamic efficiency and social welfare. This contribution provides an evidence base in support of claims of the value of the converged telecommunications ecosystem for developing countries. It evaluates how ecosystem stakeholders can find an optimal balance along multiple emerging telecommunications policy trade-offs and their implications for competition policy and regulatory option
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
