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
China's Media and Soft Power in Africa Promotion and Perceptions

It throws light not only on China's engagement with Africa but also on how China's increasing influence is received in the African media
Everyday Media Culture in Africa: Audiences and Users
No full textAfrican audiences and users are rapidly gaining in importance and increasingly targeted by global media companies, social media platforms and mobile phone operators. This is the first edited volume that addresses the everyday lived experiences of Africans in their interaction with different kinds of media: old and new, state and private, elite and popular, global and national, material and virtual. So far, the bulk of academic research on media and communication in Africa has studied media through the lens of media-state relations, thereby adopting liberal democracy as the normative ideal and examining the potential contribution of African media to development and democratization. Focusing instead on everyday media culture in a range of African countries, this volume contributes to the broader project of provincializing and decolonizing audience and internet studies
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
Decolonizing and provincializing audience and internet studies: contextual approaches from African vantage points
No full textResearching African media audiences and users is urgent more than ever because of the rapidly changing media landscape on the continent in the last few decades. In recent years, media content on the continent has become more diversified as a result of the liberalization of broadcasting, the emergence of private radio and television stations and the growing availability of foreign channels via satellite television. Most African countries have also experienced a rather spectacular growth in access and availability of both mass media devices and digital technologies. In the late 1990s, access to television sets and radio receivers was limited, with 22 percent of Africans having access to a radio in 1997, and only 6 percent reporting to own a television set.1 Although no recent comprehensive statistics are available for the continent, country surveys suggest sharp increases in access to mass media devices in recent years. For example, in 2013, 76 percent of Ghanaians reported to have access to a television while 84 percent had access to a radio.2 Access is likely to be significantly lower in rural as compared to urban areas, and newspapers continue to have fairly modest circulation rates and are often only affordable to a minority of urban readers
Racism, Ethnicity and the Media in Africa
No full textSince the colonial era in Africa, racism and ethnicity have largely led to serious conflicts – the Nigerian-Biafran War, killings in Darfur, xenophobic attacks in South Africa - that have cost lives and undermined efforts to achieve national cohesion and meaningful development on the continent. This book sets about rethinking the role of media and communication in perpetuating, reinforcing and undermining racism, ethnicity and other discriminations across Africa. It goes beyond customary discussions of representation of racism and ethnicity to question the role played by specific media institutions. Topics and issues covered include racism in South African newspapers, pluralist media in Kenya, media discourses on homosexuality in Namibia, and the politics of 'African News' in Nigerian newspapers
Engaging with China’s Soft Power in Zimbabwe: Harare Citizens’ Perceptions of China-Zimbabwe Relations
Full text linkAfricans have responded to China’s growing soft power or charm offensive in many ways but this has hardly been studied. Mano investigates the responses to China’s soft power in Zimbabwe, a key ally with a Look East “policy’ since 2002. While “win-win” trade, media and cultural linkages between China and Zimbabwe have been growing rarely has there been research focused on how this has influenced how Beijing is perceived amongst Africans. Using a survey of residents of Harare, Zimbabwe’s capital city, Mano investigates the emerging perceptions of China’s interventions in Zimbabwe. The findings contradict official claims of a mutually beneficial cosy South-South relationship. Harare residents predominantly perceive China as a “new colonial” power out to “loot” Zimbabwe’s natural resources. They criticise China’s obsession with profits at the expense of human rights. The chapter discusses such views in relation to media portrayal of China. Beijing will need to do more to reassure people in Harare and other places in the Global South about its real intentions in human development
