The greater part of land in the area south of Pretoria is underlain by dolomite from the Chuniespoort Group of the Transvaal Supergroup. In South Africa dolomite rock has a notorious reputation for the formation of sinkholes and subsidences. Thousands of people reside and work in the Centurion area, where numerous sinkholes have occurred causing damage and in some instances loss of property. Centurion has rapidly densified over the last 40 years. This study deals with the hazard of sinkhole formation in the Centurion CBD and surrounding area as well as comparing the Method of Scenario of Supposition by Buttrick and van Schalkwyk (1995) based on an ‘abused’ land use situation to this ‘managed’ area in Centurion. Various classification systems have been proposed since the 1970’s in an attempt to evaluate the stability of sites on dolomite in South Africa and a summary of each are provided in the dissertation. The classification system that is currently used in South Africa is the method proposed by Buttrick (1992) which is known as the Method of Scenario Supposition. A total of 119 sinkholes have been recorded in the Centurion CBD area since the early 1970’s. Three lives havebeen lost as a result of a sinkhole in the area and a total of seven houses or units had to be demolished. Draft guidelines for allocation of each hazard class has been developed, which is referred to as the proposed ‘Modified Method of Scenario Supposition’. This is mainly based on the dolomite bedrock depth and the mobilization potential of the overlying horizons. Eight Inherent Hazard Classes are present which classify an area into having a low, medium or high hazard of sinkhole formation. After each borehole was assigned its specific inherent hazard class, the information was recorded in ESRI ArcGIS® software. The Spatial Analyst® extension of ArcMap® was used to create a map showing the areas of low, medium and high hazard of sinkhole formation. The map generally indicates a medium to high susceptibility to sinkhole formation in the Centurion CBD area with pockets of low hazard areas. This hazard map was then used to make recommendations for each of the eight Inherent Hazard Classes on suitable development types as per the draft SANS 1936-1:2012 guidelines. Various methods are used to calculate the hazard of sinkhole formation using data such as the historicaloccurrence of sinkholes, geological information and the hazard map. These results are used to compare this ‘managed land’ to the ‘abused land’ scenario used by Buttrick and van Schalkwyk (1995). Overall, the hazard for sinkhole formation in the Centurion CBD area does not correlate well with the method proposed by Buttrick and van Schalkwyk (1995). According to the anticipated number of events by Buttrick and van Schalkwyk far more sinkholes should have occurred in the high hazard areas. In contrast, the most sinkholes in the Centurion CBD area occurred in the areas classified as having a medium hazard for sinkhole formation. / Dissertation (MSc)--University of Pretoria, 2013. / Geology / unrestricted

The aim of this paper is to investigate how two Pauline pericopes (Gal 3:21–26 and Rom3:21–24) can help us to understand Matt 8:5–13. The paper has four research questions: Whatdid the role of πίστις (“faith” or “trust”) played in Roman culture in general? What role did itplay in the centurions’ relationship to both superiors and subordinates in the Roman’s army?Which principle of faith does Paul establish in Gal 3:21–26 and Rom 3:21–24? How canPaul’s principle be used as a key to understand the faith of the centurion in Matt 5:8–13? Tofind the results of the four research questions, the paper used qualitative method throughsocial-rhetorical Criticism and narrative method. The results of this paper show that theGreco-Roman society was immersed in the ideology of patronage where there was always abeneficiary and a client. Πίστις means two sorts of relationship, one that was vertical and theother that was horizontal. Paul presents πίστις as the one who has divided the time in twoperiods. the old period that was under the power of sin and the new period that is under thepower of faith. The purpose of God was to save the whole creation through πίστις Χριστοῦ.Believers in πίστις Χριστοῦ are the coheirs of Abraham as “spiritual” descendants. Finally,Πίστις Χριστοῦ unites people of different social and ethnical status as one family. Thus,according to the Matthean point of view, the people who do not believe in πίστις Χριστοῦwill be judged by God.

Customer service excellence (CSE) is the common thread that binds all businesses; as without customers no trade can take place. The South African retail sector is one of the drivers of the economy and it is important that CSE is continuously monitored to ensure that standards of excellence are maintained. What remains unknown and unmeasured is the impact of the employees and the organisation on CSE. The retail sector is dependent on its customer facing employees to be the face and character of the store. Investment in advertising and other media exposure must ultimately be tested when a consumer visits a store and experiences the CSE on the ground and in real time. The investment for the retailer becomes worthwhile if the real face of the company reflects the promises made in the media; and that is in the hands of the men and women who work in the stores. This study sought to find out the impact of employees and organisations in the Centurion mall based retail stores on CSE. Literature was reviewed and quantitative and qualitative research methods was undertaken by means of questionnaires that were distributed to the staff and management of national branded stores in the malls around Centurion. The results obtained were then discussed in terms of each variable tested. The study found that organisational commitment, employee education and employee training have a strong relationship to customer service excellence.

M. Tech. Business Administration / This study was motivated by the lack of adequate convenience retail shopping facilities for the residents of the study area, comprising Thatchfield Residential Estate, The Reeds, Heuweloord and a small portion of Rooihuiskraal. Tenants generate the income for a shopping centre and therefore the value of this type of retail property to the owners depends on the forecast of consumer demand for the products or services sold by tenants. Through balanced tenancy, the stores in a planned shopping centre complement each other in the quality and variety of their products offerings, and the type and number of stores are linked to the overall need of the population of the catchment area.

A vegetation survey was conducted on the newly acquired farm portions of the farm Doornrandje 386 JR, which are being incorporated into Gauteng Department of Agriculture and Rural Development’s protected area expansion. This study provides an ecological basis for establishing an efficient management programme for the area. From a TWINSPAN classification, refined by Braun-Blanquet procedures, five plant communities were identified. A classification and description of the major plant communities is presented. Descriptions of the plant communities include characteristic species, as well as prominent and less conspicuous species of the tree, shrub, herb and grass strata. Floristic analyses of the vegetation and a biodiversity comparison of the different plant communities found on the farm are also undertaken. This study proves that the extended land incorporated into the Reserve contributes to the biological diversity of the study area. / Environmental Sciences / M. Sc. (Environmental Science)
