Science Communication in South Africa
Get PDF"Why do we need to communicate science? Is science, with its highly specialised language and its arcane methods, too distant to be understood by the public? Is it really possible for citizens to participate meaningfully in scientific research projects and debate? Should scientists be mandated to engage with the public to facilitate better understanding of science? How can they best communicate their special knowledge to be intelligible? These and a plethora of related questions are being raised by researchers and politicians alike as they have become convinced that science and society need to draw nearer to one another.
Once the persuasion took hold that science should open up to the public and these questions were raised, it became clear that coming up with satisfactory answers would be a complex challenge. The inaccessibility of scientific language and methods, due to ever increasing specialisation, is at the base of its very success. Thus, translating specialised knowledge to become understandable, interesting and relevant to various publics creates particular perils. This is exacerbated by the ongoing disruption of the public discourse through the digitisation of communication platforms. For example, the availability of medical knowledge on the internet and the immense opportunities to inform oneself about health risks via social media are undermined by the manipulable nature of this technology that does not allow its users to distinguish between credible content and misinformation.
In countries around the world, scientists, policy-makers and the public have high hopes for science communication: that it may elevate its populations educationally, that it may raise the level of sound decision-making for people in their daily lives, and that it may contribute to innovation and economic well-being. This collection of current reflections gives an insight into the issues that have to be addressed by research to reach these noble goals, for South Africa and by South Africans in particular.

Cultural differences and confidence in institutions: Comparing Africa and the USA
Get PDFA comparison was undertaken of confidence in 17 institutions in Ghana, Nigeria, Zimbabwe and the USA using data from the World Values Survey to find shared valuations and distinguishing characteristics as markers of cultural categories. Frequencies and rankings were examined and exploratory factor analysis was used to find plausible meanings of groups of institutions. The findings show that, although African respondents score institutions higher than their US counterparts, the rankings vary. With frequencies, the meaning is manifest. The analysis shows that 10 institutions load similarly on one latent variable and their combinations with the others indicate culture-specific characteristics. The latent variables were named ‘not-for-profit’, ‘for-profit’, ‘political’, ‘watchdog or fourth estate’ and ‘social order’ and they show Ghana is closer to the USA than to Nigeria, which is closer to Zimbabwe. The ‘not-for-profit’ variable is more important in the USA and Ghana and ‘political’ is more important in Nigeria and Zimbabwe. Institutional-specific loadings show that whereas the police and courts are grouped as ‘political’ in Nigeria, in other countries they belong to ‘social order’; and while universities are perceived as ‘for-profit’ in Africa, they are ‘not-for-profit’ in the USA. Comparing frequencies and rankings or dividing along the lines of individualistic versus collective or private and public sectors, masks the dynamic distribution of the systems of meaning in the local cultures; the latent variables approach therefore offers a more conceptually sound categorisation informed by shared and distinguishing institutions.
Significance:
• Nigerians, as at the time of the survey, were yet to perceive the principles of separation of powers between political institutions, the judiciary and the police – an essential feature of a good democracy and a characteristic of other countries in the study. Zimbabweans and Nigerians perceive their public institutions in generally the same way with the domination of the political establishments while Ghanaians are closer to the USA in terms of the values they attach to their establishments with the most important group being the charities. The universities in Africa, as well as the civil service in Nigeria, are associated with business/ profit centres with the Nigerian labour movement also seen as political. The army also remains relevant as a part of the fourth estate in Ghana and Nigeria
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
African academics keep faith with both science and religion

Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe 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 colonial effect: language, trust and attitudes to science as predictors of vaccine hesitancy across Africa
No full textPerceptions of vaccine safety, importance and effectiveness are at the core of vaccine hesitancy around the world, and Africa has had its own share of vaccine revolts. This study uses the 2018 Wellcome Global Monitor on public perceptions of vaccines in 40 African countries to examine the predictors of vaccine hesitancy. It examines levels of hesitancy from a language perspective, comparing French speakers with others, mostly English speakers. Results show that French speakers were significantly more hesitant about importance and safety, while English speakers and others were more hesitant about effectiveness. This reflects the continuing influence of colonial ties on African countries. Respondents with high levels of trust in social actors (such as national government, journalists, people neighborhood, doctors and nurses) were also more hesitant about the safety and effectiveness of vaccines, indicating the importance of non-scientists in influencing vaccine hesitancy. Those with high levels of education were more likely to be hesitant about vaccines in general, indicating that having more education may have an opposite effect. Perception of science as progress was significant for all three hesitancy types, indicating that Africans with more progressive attitudes were less likely to worry about the importance, safety and effectiveness of vaccines. At the country level, there was no overarching predictor, indicating the strong role of local social and cultural factors. These findings improve our understanding of the drivers of vaccine hesitancy in Africa and provide valuable input for future vaccine policy and health-awareness campaigns
