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
#RESISTHUDUMANAMBA: KENYAN GOVERNMENT AT A CROSSROAD
No full textIn the past few years, Kenya’s digital landscape has transformed and this has been made possible by proliferation of the usage of digital technologies, particularly - mobile phones. Due to increased access to digital technologies, faster internet speeds, increased securitization among other issues, data on individuals in online spaces has also increased. Recently, the government rolled out a National Integrated Identity Management System (NIIMS) which is meant to capture biometric data but this has generated a huge debate online in Kenya under the hashtag #ResistHudumaNamba. This paper will therefore examine the following issues: What has contributed to the decline of trust between the government and its citizens when it comes to internet technologies? What are the actual sentiments given for and against in the introduction of Huduma Number? What are the underlying reasons for continued registration of individuals in Kenya? This research will be a qualitative research study. Data will be generated from social media sites (Twitter and Facebook), as well as blog posts and newspaper articles. A discourse analysis of the events around #ResistsHudumaNamba in these sources will be done so as to answer the research questions. This research has the potential to contribute to literature on trust in sub-Saharan Africa as well as establish trust issues between government and citizens when digital technologies are involved
#DigitalActivism: a study of socio-political movements in Kenya
No full textA dissertation submitted to the Department of Media Studies, Faculty of Humanities, University of the Witwatersrand, Johannesburg, in fulfilment of the requirement for the degree of Doctor of Philosophy, 2021Kenya is regarded as one of the technological hubs in Africa, and the increased use of internet technologies have become part of the everyday life of most citizens, especially in urban areas. Internet technologies have become essential in political participation in Kenya, particularly among the marginalised communities such as the youth and women. This research explores the place of social media in socio-political movements, the dynamics of protests and the socio-political issues that shape socio-political movements. Empirical research on digital activism in Kenyan context is scarce and the few studies that exist which explore social media as a tool for political change are not based on empirical evidence and they offer less understanding on the dynamics of political led and grassroots-led protests in Kenya and the role different media play in the outcome of the protests. This research study aims to fill this gap. This research draws inspiration from the theories of social movements such as Castell’s network theory, resource mobilisation theory, and the theory of collective identity and collective action. This research adopts a qualitative research design and a multiple case study research approach. Three socio-political movements (also referred to as forms of digital activisms in this study) that happened in Kenya between 2013 and 2016 were selected to study the phenomenon. These included two grassroots movements -#OccupyParliament and #OccupyPlayground and one political led movement #IEBCMustGo. This research analysed both the actors and the contents of the protest. Firstly, interviews were conducted with individuals who shaped or took part in those movements, as well as with individuals who were touched by them, as targets or active observers from the civil society organisations, the media, religious leaders, and politicians. Secondly, this research analysed the content of the three movements from social media sites, blogs, and newspaper articles. The use of these sources of data made it possible to understand the dynamics of protests in digital activism in grassroots-led and political led protests. The findings of this research indicated that, firstly, there had been a trajectory of using the media for activism since the pre-independence period in Kenya. Using the media for activism in the pre-independence and post-independence eras have continuously been shaped by various political environments and leadership –from a more restricted media environment in the colonial period to a free media in the current post-independence era. Although the current political environment has allowed grassroots and political led activism to thrive, government restrictions still exist during socio-political movements. Secondly, the findings indicated that grassroots-led protests and politically led protests use various media differently for activism, mostly due to the existing socio-political factors. Thirdly, the findings of this research indicated that offline activities during protest such as street protests, meetings, and court processes and which are complemented by online protests are all critical in realising socio-political change. This applies to both grassroots and political led protestsC
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
