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
The nationalist discourses of an African ruling party : an exploration of ZANU-PF print media election advertisements for the July 2013 elections
Full text linkD.Litt. et Phil. (Communication Studies)Abstract: Post-2000 Zimbabwe has been characterised by massive political contestations mainly between the Zimbabwe African National Union Patriotic Front (ZANU-PF) government and the Movement for Democratic Change (MDC). The struggle for power has oftentimes been nasty and brutal. ZANU-PF largely accuses the MDC of being ‘puppets’ of the British and Americans whilst MDC accuses ZANU-PF of ‘dictatorship’. This rivalry has largely been more pronounced during election periods where it takes place through, among others, political advertisements, music and election rallies. Despite the centrality of political advertising in this contest, there has been little study of political advertising in Zimbabwe. Many of the studies of Zimbabwean elections and ZANU-PF discourse focused on media coverage of elections, official speeches, music and alleged use of violence by ZANU-PF to retain power. But these studies of ZANU-PF discourse have tended to either be uncritically pro-ZANU-PF or anti-ZANU-PF (Moore, 2012). This is a result of scholars’ abysmal and inappropriate application of Western theory in African contexts. It is equally a result of post-colonial theory’s re-inscription of that which it seeks to undo. The study proposes utilising a multi-theoretical approach that borrows from Western theory, post-colonial theory and decolonial theory in the study ZANU-PF advertisements. It employs thematic analysis, critical discourse analysis and semiotic analysis. The study found out that ZANU-PF discourse is fluid and context-specific; borrows from the present, past and future and is not always about the liberation struggle. It also established that ZANU-PF only engaged the MDC-T and ignored smaller parties and refrained from attack advertising. Finally, Robert Mugabe, the ZANU-PF leader and presidential candidate, was a key component of ZANU-PF’s electoral product. Interestingly, from the findings, the study concludes that; the predominance of Mugabe’s images is not a sign of the personalisation and patriarchal nature of Zimbabwean politics; comparative advertising and negative advertising are central political advertising tactics in post-colonial contexts such as Zimbabwe as much as in established democracies. The study, some of whose sections have already been published (see Chibuwe 2013), suggests the need for a new theory in the reading of the ZANU-PF discourse

Language and the (re)production of dominance: Zimbabwe African National Union-Patriotic Front (ZANU-PF) advertisements for the July 2013 elections
Full text linkAbstract: Language is a political tool used to legitimise, delegitimise, produce and (re)produce dominance. In Zimbabwe, ZANU-PF advertisements for the July 2013 elections were an attempt to deploy language to (re)produce dominance. The advertisements were produced in the context of a power-sharing government comprising ZANU-PF and the MDCs. Adopting sign theory, the article uses legitimation analysis to explore the ways in which ZANU-PF used language to retain dominance. Research revealed that ZANU-PF legitimated its dominance on the basis of performance, for example, implementing the multiple currencies system after the Zimbabwe dollar’s collapse and delivering a constitution that guarantees the values espoused by the liberation struggle. Mugabe’s incomparable “wisdom and deftness” in handling matters of state, ZANU-PF’s care for ordinary urban ratepayers and economic indigenisation were used to justify the party’s dominance. It also legitimised its rule by portraying the MDC-T as an uncaring, dishonest and sell-out party, thus delegitimising it while skilfully concealing its own blame in the collapse of the economy post-2000
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
