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
Linguistic landscapes and dominant language constellations: the multilingual behaviour of minoritised migrant populations in Lusaka, Zambia
No full textWithin the broader theoretical and methodological contexts of linguistic landscapes, where language(s) displayed and used in public spaces serve as analytic lenses, this paper draws on the public spaces of Bauleni township, a peri-urban community of Lusaka, Zambia (South-Central Africa) to describe the multilingual behaviour of migrant populations. Focusing on the presence (and visibility) of Mambwe-Namwanga, two minoritised language groups in Zambia’s sociolinguistic mix, the article shows that as people migrate, it is not always the case that they lose their language(s) for they carry with them their linguistic repertoire which they blend with those found in the new space. To this end, the article uses the outlook of the linguistic landscape and connects it to the dominant language constellations of the Mambwe-Namwanga migrant populations. It argues that while adopting the languages found and used in Bauleni, Mambwe-Namwanga actors simultaneously imprint their presence on the linguistic landscape. These imprints serve as cultural expressions, markers of self-assertion, and symbols of identity, reflecting the dynamic interplay of language and migration in the construction of multilingual spaces
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
The linguistic landscape of the University of Zambia: a social semiotic perspective
Full text linkThesisThis dissertation presents the linguistic landscape of Zambia’s flagship university, the
University of Zambia. In keeping with both the custom and recent trends in linguistic
landscape theorizations, the study conceived as “The Linguistic Landscape of the
University of Zambia: A Social Semiotic Perspective” conflates, as a sub-discipline of
sociolinguistics, both language and semiotic materialities that enact and transact meaning.
Drawing on Geosemiotics, as well as Multimodality together with its extended notions of
semiotic remediation and Resemiotisation for theory and Ethnography for methodology,
the study was specially privileged to uncover the sociolinguistic situation and the material
culture in the multilingual and multimodal landscapes of the University of Zambia.
Through a critical engagement with the 416 digital images of signage in place, an inquiry
into the sociolinguistic situation unearthed an instance of the global in the local as the
dominance of English over Japanese, Chinese and the apparent absence of indigenous
languages on monolingual signs was noted. Owing to the symbolic and indexical
presence of Chinese and Japanese, a place of linguistic contestations and legitimization of
languages, control and superiority is foregrounded. Indigenous languages are spotted only
on bilingual signs (with English) resemiotizing and recontextualizing ideological leanings
of humanism and Pan-Africanism. English, Ila, Tonga, Bemba, Lozi, Nyanja and
Mambwe constitute the repertoires of social actors carving out a complex multilingual
context as languages are often co-deployed through translanguaging, mixing, semiotic
coinages and truncated forms thereby informing normative societal practices of the late
modern age.
With regard to material culture, the fluidity of both space and meaning seen through
juxtaposed semi-permanent and transitional spaces entails the transient nature of
messages, meaning and discourses in place. Consequently, this reinforces the notion of
linguistic landscape as cities of perpetual (re-)production, (co-)construction and
consumption evidenced by discourses and semiotic materialities which are repurposed,
remediated and crafted anew, thereby breeding highly complex meaning making systems.
At the same time, these spaces are commercially, religiously and politically themed,
reclaimed and contested material environs where even the consumption of artifactual
materiality contests and upholds mobile identities amidst semiotic aggregation as
meanings are drawn from the intermingling of social actors, language and space.

Legitimization and recontextualization of languages: The imbalance of powers in a multilingual landscape
No full textWe use the uneven distribution of languages in the public spaces of the University of Zambia and the voices and narratives that emerge to argue for legitimization and recontextualization as critical components in the presence and contestations of languages. Using data from interviews and photographs of signage in place, we show legitimization of foreign languages in which English, Japanese, and Chinese forge a place of linguistic contestation and legitimization through control and superiority. We argue for the apparent hegemony of foreign languages and the striking paucity of monolingual signage of indigenous languages as the imbalance of powers. While the former shows the influence of the global in the local, the prospects for the latter continue to diminish as their chances and opportunities as linguistic capital for wider/global communication do not look so favourable. We conclude with the glaring reality of recontextualization as capital for the display of indigenous inclined discourse
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
