Thesis (M.A. (Media Studies)) -- University of Limpopo, 2021 / The emergence of democracy in South Africa brought a fallacious rainbow nation to permit all citizens to benefit from equal opportunities regardless of colour. The national broadcaster, SABC as a tool of transformation to promote multiracialism was meant to depict balanced representations of all races through its programmes such as soap operas. This study’s aim was to examine the depiction of racial characterisation in Skeem Saam which is broadcast by the SABC. The study employed a qualitative approach which allowed the use of descriptive analysis. Purposive sampling was used to determine the soap opera as the most appropriate to examine racial characterisation. The data was collected through qualitative content analysis which enabled the researcher to peruse Skeem Saam’s episodes which address the study’s objectives. Thematic content analysis was used to analyse the data which enabled the analysis of ten characters and the contexts these characters are portrayed in. The study found that there are negative racial misconceptions and stereotypes attached to Black character roles through occupational roles, personality traits, social and economic status as compared to White character roles. Therefore, that there is misrepresentation of Blacks through roles played by Black characters. The study recommends a need for transformative policy amendments which will bind soap opera producers to include realistic and balanced representations of race and gender. Narrative formations should also feature realistic developments in society rather fictional storylines that run at the expense of daunting Blacks growth in South Africa.

A bio-inspired robotic underwater vessel was developed to test the effect of fin morphology on the propulsive performance of caudal fin. The robotic vessel, called The Bullet Fish, features a cylindrical body with a hemisphere at the forward section and a conical body at the stern. The vessel uses an oscillating caudal fin for thrust generation. The robotic vessel was tested in a recirculating flume for seven different caudal fins that range different bio-inspired forms and aspect ratios. The experiments were performed at four different flow velocities and two flapping frequencies: 0.5 and 1.0 Hz. We found that for 1 Hz flapping frequency that in general as the aspect-ratio decreases both thrust production tends and power decrease resulting in a better propulsive efficiency for aspect ratios between 0.9 and 1.0. A less uniform trend was found for 0.5 Hz, where our data suggest multiple efficiency peaks. Additional experiments on the robotic model could help understand the propulsion aquatic locomotion and help the design of bio-inspired underwater vehicles. / Includes bibliography. / Thesis (M.S.)--Florida Atlantic University, 2017. / FAU Electronic Theses and Dissertations Collection
