Thesis (MScEng)--Stellenbosch University, 2012. / ENGLISH ABSTRACT: A methodology is developed to manage the large number of RFI Culprits on a new Radio Telescope location such as the South African site being developed in the Karoo, both during construction and ongoing operations. The requirement for RFI control is presented, with brief reference to the more traditional methods used by other Radio Telescope observatories. The new approach is then presented, based on methods used in the engineering field of Logistic Engineering. Three case studies are used to illustrate how the approach can be applied. Finally, recommendations are made on how the approach can be implemented for new Radio Telescope projects. / AFRIKAANSE OPSOMMING: ‘n Metodolgie word ontwikkel vir die beheer van die groot aantal Radiofrekwensiesteurings oortreders by ‘n nuwe Radio Teleskoop terrein, soos die Suid Afrikaanse terrein wat huidiglik in die Karoo ontwikkel word. Die metodolgie geld beide gedurende konstruksie en gedurende bedryf. Die behoefte vir RFS beheer word aangebied, met kortlikse melding van die meer tradisionele metodes wat ander Radio Teleskoop Sterrewagte gebruik. ‘n Nuwe aanslag, gebaseer op die metodolgieë van Logistieke Ingenieurswese, word dan aangebied. Drie gevallestudies wys hoe hierdie nuwe aanslag toegepas kan word. Laastens word aanbevelings gemaak om hierdie nuwe aanslag met nuwe Radio Teleskoop projekte te implimenteer.

Thesis (M. A. (Criminology and Criminal Justice)) -- University of Limpopo, 2018 / Vigilantism is a contentious issue that will persist into the future for as long as crime exists. This research aimed at determining community’s perception on vigilantism. The Criminal Justice System has failed community of Matome Village, in the sense that they lost trust and lacked confidence in CJS. Actions involved in vigilantism are not only an expression of people’s anger or frustration but also of their fear. This study adopted both qualitative and quantitative approaches. Probability sampling (Stratified sampling) was used to select participants. For qualitative approach an interview schedule with prearranged questions was conducted and used in both focus group1 and 2 interviews. Focus group 1 consisted of 10 participants, while focus group 2 consisted of 8 participants. For quantitative approach, 80 questionnaires with close-ended and open-ended questions were distributed among community members who took part in the study, and the aim was to get their opinions and experience of vigilantism. The data collected was analysed (thematic content analysis was used) and interpreted by copying exactly words that were said by the participants. The study documented the disadvantages and consequences of vigilantism to fill in the existing gaps of the dangers of vigilante incidents in the literature. Strain theory by Robert Agnew was applied as the suitable theory which best explains why people resort to partake in vigilantism. The research identified factors which contributed mostly to vigilantism, such as: a way of protection and desire for revenge (anger and frustration).
