A dissertation submitted to the the Faculty of Arts in fulfilment of requirements of the degree of Master of Arts in the Department of Criminal Justice at the University of Zululand, South Africa, 1995. / This research aims at investigating the image of traffic policing in Transkei. To achieve this goal, questionnaires were distributed to a purposive sample of 600 respondents. Five towns whose people are exposed to traffic policing were targeted, namely: Umtata, Butterworth, Engcobo, Qumbu and Libode. The researcher personally collected the questionnaires. A total of five hundred completed questionnaires were collected. To achieve reliable results, Chi-square, F-test and t-test have been implemented to test for significant differences. The attitudes of the respondents have been measured with regard to two traffic institutions in Transkei, namely: Municipal and Provincial traffic institutions. Traffic order cannot be achieved in Transkei if a sound partnership between the traffic police and the public is lacking.

I en värld där kraven på flexibilitet, säkerhet och hårdvaruoptimering är nyckelfaktorer när det kommer till att välja IT-miljöer för företag blir virtuella skrivbord mer och mer poulära. Med dessa miljöer finns det också problem när det kommer till användarupplevelsen om nätverket ifråga inte kan uppfylla de krav som ett sådant system ställer. I detta arbete undersöks implikationerna vissa nätverksvariabler kan ha för en Virtual Desktop-infrastruktur, VDI. För att belysa dessa problem har två tester utförts på en VDI miljö. Det första testet gick ut på att mäta latensen då skrivbordsmiljön renderades för klienten från virtualiseringsservern vid olika nätverksdiamterar. Det andra testet gick ut på att mäta samma latens vid olika nätverksbelasting på anslutningen mellan klienten och virtualiseringsservern. När det blev tydligt att nyckelfaktorn var nätverksbelastningen skapades ett test för att undersöka klientens möjlighet till påverkan av bandbredden. Överföringen av data till användarens lokala skrivbord som i förlängningen huseras på virtualiseringsservern tog upp hela bandbredden och lämnade inget för VDI-trafiken och stänger i förlängningen ner hela VDI systemet. Detta löstes genom att implementera Quality Of Service medelst Traffic Policing . Därmed kan användarens möjlighet att nyttja bandbredden till virtualiseringsservern begränsas. / In a world where the demand for flexibility, security, and hardware optimization are key factors when it comes to implementing a corporate IT environment Virtual Desktop solutions a gaining more and more ground. With these environments there are also issues when it comes to user experience if the network in question is unable to fulfill the specifications that such an environment requires. We have looked at the implications some network variables might have for a VDI solution. To shed a light on these issues we have conducted two tests in an VDI environment. The first test consisted of measuring the latency at which the desktop on the client was rendered from the virtualization server at different network sizes. The second test was to measure the same latency at different bandwidth loads on the line between the client and the Virtualization Host. As we realised that the key factor was the bandwidth load, we made a test to measure the way a client could influence that bandwidth. We saw that by transferring data to the desktop (i.e. the Virtualization Host) one user could personally take up the whole bandwidth and leave noting for the VDI traffic, rendering it useless. This was solved by implementing Quality of Service in the form of Traffic policing, thus restricting the amount of bandwidth the user could use for file transfers.

The Johannesburg Metropolitan Police Department (JMPD) is one of the South African institutions with growing levels of corruption. This is despite the presence of several anti-corruption strategies as well as institutions implemented to deal with this epidemic. The ineffectiveness of these strategies and institutions is attributed to, amongst others, the application of ineffective detection methods. The under-detection of corruption in the JMPD is affecting road safety, the economy, and the image of the JMPD itself. It is against this background that the researcher sought to establish how intelligence analysis could add value in detecting corruption in the JMPD. A qualitative research approach was applied to investigate this problem. As such, it has been proven that the use of hotlines and the over-reliance on whistleblowers is less effective in detecting corruption in the JMPD. The results have further shown that intelligence analysis may add value in detecting corruption in the JMPD. / Umnyango wamaphoyisa edolobha elikhulu eGoli (JMPD) ungenye yezikhungo zaseNingizimu Afrika ezithola amazinga akhulayo enkohlakalo.
