- Description: In this paper we study packet delay and loss rate at the University of Fort Hare network. The focus of this paper is to evaluate the information derived from a multipoint measurement of, University of Fort Hare network which will be collected for a duration of three Months during June 2011 to August 2011 at the TSC uplink and Ethernet hubs outside and inside relative to the Internet firewall host. The specific value of this data set lies in the end to end instrumentation of all devices operating at the packet level, combined with the duration of observation. We will provide measures for the normal day−to−day operation of the University of fort hare network both at off-peak and during peak hours. We expect to show the impact of delay and loss rate at the University of Fort Hare network. The data set will include a number of areas, where service quality (delay and packet loss) is extreme, moderate, good and we will examine the causes and impacts on network users.

- Description: With the advent of a democratic South Africa in 1994, national public administration has effected reforms to improve government performance and service delivery. The importance of education for the development of excellence, expertise and knowledge leading to overall development in economy cannot be undermined. This has necessitated a sound strategy for the development of higher education in South Africa. Establishing leadership in this country is possible only when there is a developed system of higher education in which efficiency remains the sole criteria to evaluate performance. Higher education institutions are faced with an increasing number of complex challenges including implementing and maintaining a quality management system. This study seeks to explore the efficacy of total quality management as the performance enhancement instrument at Walter Sisulu University, in the Eastern Cape Province – South Africa. Relevant literature regarding quality, quality assurance, total quality management and performance management has been reviewed in order to establish and test if this study is researchable. Interviews with students have been conducted in order understand a sense of student perception towards quality assurance in the university. Observations and Staff questionnaires have been used to collect more data on total quality management and performance management system. The data collected is analysed and interpreted in chapter four and chapter five provides for findings and recommendations in concluding this study.

- Description: The Human Immunodeficiency Virus (HIV) and Acquired Immuno Deficiency Syndrome (AIDS) epidemic has had massive detrimental impacts on rural communities across Africa including in Zimbabwe. In response to the HIV and AIDS epidemic, the government of Zimbabwe has developed and adopted comprehensive programmes to address HIV and AIDS prevention, care and support. One of the critical components of these programmes relates specifically to treatment of the HIV infected given that HIV and AIDS is increasingly seen as a manageable threatening disease. However the success and effectiveness of the treatment regimen (involving antiretroviral drugs or ARVs) is dependent heavily on complete adherence to the rigid and complex regimens. It is against this background that this thesis studies a particular rural community in Zimbabwe called Chivanhu (in Masvingo Province) in terms of the relationship between rural livelihoods and HIV and AIDS (particularly HIV treatment and treatment adherence). Unlike other rural communities (notably in communal areas), Chivanhu is an informal and unstable community with a turbulent history. Most rural studies of HIV and AIDS in Zimbabwe and elsewhere in the region have focused on well-established and stable communities in which agricultural production is still of some significance. In such communities, the impact of HIV and AIDS on livelihoods is severe but, in more informal settlements, the vulnerability of households to the epidemic (and challenges pertaining to treatment adherence) is even more pronounced. Using a rural livelihoods framework, this thesis seeks to identify, understand and analyse the conditions which shape levels of adherence to HIV and AIDS in the informalsettlement of Chivanhu in Zimbabwe.
