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

Full text linkThe rhetoric, policy, practice gap: a study of online learning in Irish higher education
Full text linkOnline learning is an idea whose time has come. Even before the Covid-19 pandemic it was predicted that the global value of the online education market would reach €290 billion by 2025 (McCue, 2018). This figure is likely to have increased significantly in 2020 due to campus closures as teaching continued online. Thus, the demand for online learning is enormous and growing, even though it currently makes up less than 2% of the overall higher education market (HolonIQ, 2020).
The Covid-19 crisis has shown policy-makers and educational leaders that new models of online learning provide a means to widen access and participation in higher education. The debate surrounding the development of online learning in Ireland for promoting access and participation in lifelong learning more generally appears to be largely aspirational in the absence of a strong policy commitment and funding model to resource fully online programmes.
Set against this backdrop, this doctoral study aims to investigate a perceived gap between rhetoric, policy and practice in promoting wider access to higher education in Ireland. It involves three phases:
- Phase 1 (macro-level) consists of an analysis of relevant International policy texts;
- Phase 2 (meso-level) involves an analysis of Irish policy texts and institutional online learning strategies and initiatives through publicly available documentation; and
- Phase 3 (micro-level) adopts a case study method to “tell the story of the development of online learning” at one Irish university.
The main research findings are:
- Defining online learning is problematic. The research demonstrates that a clear, universally agreed, definition of what constitutes online learning, understood by the sector and policy makers, does not exist.
- Economic factors are the most influential drivers (and barriers) in the adoption of online learning in policy texts. Social and vocational drivers have influence, however, the most important driver is economic. Notably the pedagogical drivers for online learning in policy texts are relatively weak.
- Good policy emanates from a collaborative process which is inclusive, transparent, and credible. In order for policy to be effective and successful, all relevant stakeholders must be encouraged to contribute in a meaningful way, through a clear process. Future development of policy for online learning in Ireland needs to be more cognisant of these requirements
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
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
