What position will Central Africa adopt at the Internet Governance Forum (IGF) in Africa? To borrow an expression from Justine Diffo Tchunkam, a teacher at the University of Yaoundé II, Central Africa has a common vision, but no common position with regard to regulation of the ICT sector.
The Spear is a painting that depicts the South African president Jacob Zuma in a rallying pose, with genitals exposed. It has caused controversy and been defaced. Images of the painting have gone viral on internet. In late May 2012, the South African Film and Publications Board classified the painting, as not suitable for people under the age of 16. But in a country where one in four women is raped, who is the ban supposed to protect?

Nancy Hafkin was inducted into the Internet Hall of Fame on April 25, after 33 years promoting networks and the internet in Africa.
South Africa’s constitution guarantees freedom of expression and has been interpreted to include the right to community media and to creative journalistic content. However, online media and its regulation fall short.
After more than 30 years of working to promote information and communications technology in Africa, Nancy Hafkin was inducted into the Internet Wall of Fame. In an interview with APCNews, she shares the history of her work and that of communications technology in Africa, her interest in Africa, obstacles and achievements.
African countries lag behind the rest of the world in their use of Information and Communication Technologies (ICTs). To reduce the digital divide quickly and cost-effectively, wireless networks are considered. WiMAX (Worldwide Interoperability for Microwave Access) is a wireless broadband access technology that uses Orthogonal Frequency Division Multiplexing (OFDM) which is a multicarrier modulation scheme. OFDM presents a problem of a high crest factor or Peak to Average Power Ratio (PAPR). To circumvent this problem either High Power Amplifiers (HPAs) with large dynamic range or PAPR reduction techniques are used. The former scheme increases cost of the system while the latter introduces redundancy or distortion. A novel PAPR reduction scheme is presented. It is a combination of the ideas of Tone Reservation and Selected Mapping. The advantage of this scheme is that it has a lower complexity. It is simulated for a WiMAX system.
Lillian Nalwoga from the Collaboration on International ICT Policy in East and Southern Africa (CIPESA) coordinated research on open governance data in Uganda as part of APC’s Action Research Network project. “Citizens, academia, the private sector and civil society need to be more involved in the implementation of open governance,” says Nalwoga in an interview with APCNews.
