"Twitter is a key site for understanding the highly polarized and politicized debate around climate change. We examined large datasets comprising about 15 million tweets from different parts of the world referencing climate change and global warming. Our examination of the twenty most active users e ... mploying the term ‘global warming’ are likely to be automated accounts or bots than the most active users employing the term ‘climate change’. We used a mixed method approach including topic modelling, which is a digital method that automatedly identifies the top topics using an algorithm to understand how Twitter users engage with discussions on ‘climate change’ and ‘global warming’. The percentage of the top 400 users who use the term ‘climate change’ and believe it is human-made or anthropogenic (82.5%) is much higher than users who use the term ‘global warming’ and believe in human causation (25.5%). Similarly, the percentage of active users who use the term ‘global warming’ were much more likely to believe it is a results of natural cycles (18%) than active users who use the term ‘climate change’ (5%). We also identified and qualitatively analysed the positions of the most active users. Our findings reveal clear politically polarized views, with many politicians cited and trolled in online discussions, and significant differences reflected in terminology." (Abstract) more

"The articles contained in this special issue build on the conversations initiated at the Cairo Symposium and try to make sense of the shifts and transformations in media and gender relations in Africa. Some bring new perspectives to bear on how traditional media (newspapers, magazines, radio and te ... levision) continue to be implicated in questions of gender, while others address new questions raised by new media forms and formats. Four articles (three in French and one in English) tackle the impact of ICTs and social media from different theoretical perspectives, locations and experiences (see Palmieri, Kane, Rouamba and Mbure). Three other articles examine the representational practices of newspapers and magazines in political and social discourses relating to gender (see Anate, Ossome and Eshiet). The contribution by Chiweshe and Bhatasara reflects on popular culture, specifically the construction of gender in music, while that of Yeboah and Thompson examine on the outstanding qualities that enable three women to rise to decision-making positions in the public relations, advertising and broadcast industries in Ghana."
