    The 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

    “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

    We 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

    We 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

    International Communication: A Critical Reflection of the Major Turning Points in History

    Get PDF
    International communication was in existence since ancient days. During historical time empires, the emperors used different forms of communicating to their subject people or regions such as runners, written scripts, horn-link or drum-link (horn blowers or drummers positioned in hilly places across a region) and other forms. This paper therefore seeks to trace the historical development of international communication by critically analysing the exsiting literature. With development of technology, communication has changed certainly from the early –twentieth century days of one-way, one directional and undifferentiated flow to an undifferentiated mass. There is rise of a new communication society characterized by complex interactive network of communication.Currently we have countless forms of communication. World intelligence issues, state to state diplomacy, agreements and secret issues, world business, the need for both cultural and social exchange both at national and individual levels, social interaction, education exchange and others have been eased by the present day technological advancements such as; modern cinema, emailing, satellite broadcasting, internet information exchange, cable networks and other cross-generic or hybrid cyber-pinking. This paper foregrounds the argument that international communication is important to note that they are specific to the type of communication or media systems. Depending with ideologies and regional or continental sources, different media systems have different characteristics. For instance, western communication systems are different from Middle East or third world communication systems. Keywords: International communication, Telegraph, Radio, internet

    Online news consumption in Kenya: emerging and receding patterns among young people

    A PhD thesis submitted in (partial) fulfilment of the requirements for the award of a Doctor of Philosophy degree in Media Studies, at the University of the Witwatersrand, 2020This thesis explores news consumption patterns and habits among young people in Kenya. While there is a widespread agreement that the internet and mobile devices have reconfigured the mediascape in the Global South, it is not yet clear how the adoption and adaptation of both have shaped content (including news). Instead, much effort has been expended on how the relatively high internet and mobile penetration rates could ‘transform’ and possibly help states in the Global South, achieve their development goals. In addition, existing literature has devoted attention to how traditional news organisations have embraced social media and messaging applications in their routine news gathering, processing and dissemination practices. This approach has obscured rather than reveal the news users’ experiences, particularly the kind of news genres accessed and consumed. It also underplays the motives behind such choices, against the proliferation of 'fake' news. In this regard, I combined the rooted Uses and Gratifications theory (U and G) and the relatively new concept of “scalable sociality” as the two main pillars of an original framework aimed at analysing and explaining young people’s agency in news consumption. Uses and gratifications was particularly useful in framing research questions on news access and the enablers of the high mobile and internet penetration rates in Kenya. On the other hand, Scalable sociality was valuable in illuminating online news consumption processes––including how news mutates across public and private spaces of socialities. The non-normative third wave African scholarship was embraced to explain unfamiliar news use and Sponsors: Enter the names of any sponsors and/or funding codes in the box. consumption patterns among young people. This study embraced a mixed-methods approach. The first phase was a survey involving 800 respondents in two academic institutions. The objective of the survey was to map the emerging and receding patterns of news consumption. The second phase comprised of eight focus group discussions (FGDs) aimed at nuancing the emerging themes of news consumption revealed by the survey. Lastly, ethnographic methods (online and offline observations) were useful in providing a more holistic understanding of how internet-enabled mobile devices are interwoven in the daily lives and news consumption experiences of young people. Findings revealed how news consumption among young people in Kenya is a complex and multi-layered process, often defying pre-existing conceptions. While statistics on the internet and mobilepenetration rates tend to be used to frame Kenya as a leading country in the African digital space, these obscure the specific ways in which young people creatively navigate barriers to access, through hacking and developing parallel markets for cheap bundles. Regarding the content that is consumed on social media, the prevalent news sub-genre is political news. Paradoxically, young people consume political news not to become responsible civic agents, but rather for their entertainment value. They enjoy the ‘drama’ staged by political leaders as they transgress their private lives in public spaces. Therefore, while news exposure occurs across public and private platforms, news deliberations occur on ephemeral private platforms such as WhatsApp. Finally, the perceived prevalence of ‘fake news’ on social media has increased the stakes of traditional media (radio, newspapers and television) as the most trusted news sources online and offlineCK202

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    We 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
