This study focuses on determining the quality of soil and groundwater at the Onderstepoort Municipal Solid Waste (MSW) landfill site. The study area is situated in Pretoria North, a jurisdiction of City of Tshwane Metropolitan Municipality (CTMM). Samples were collected from three different spheres (i.e. leachate, soil and water) in the study area, to determine the concentration of metals accumulated in each sphere. The three spheres provided an overview of the contaminants found in leachate, soil and water. The laboratory analyses using Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) indicated that soils in the site have been severely contaminated with heavy metals. Higher concentrations of heavy metals occurred in the soils compared to the groundwater surrounding the landfill site and this may be due to the ability of the soil strata to absorb the contaminants caused by the landfill leachate. In essence, the measurements indicated that leachate soil has very high pollutant levels (0.21 to 2505.61 mg/kg); soil was characterised by fairly-high pollutant levels (0.03 to 638.27 mg/kg); leachate solution has given rise to moderate pollutant levels (0.01 to 2.296 mg/L) and water resources have low-moderate pollutant levels (<0.0001 to 0.456 mg/L) depending on the location. Furthermore, the findings indicated that the soil was contaminated with lead, cadmium, copper, zinc and nickel, and the concentration increases particularly where the generation of leachate is taking place. Groundwater, particularly in Borehole 2 has been moderately contaminated with nitrite, calcium and manganese. The findings also indicated that the concentrations of contaminants become high in borehole located close to the waste dump and decrease further away from the waste dump. The chemical analysis of this groundwater indicated that the concentrations of chemical properties have increased since the year 2009. This was determined through the comparison of groundwater study undertaken in 2009 to the current study results obtained. The site geological formation, Rustenburg Layered Suite is known to contain the anomalies of nickel, chromium, vanadium, copper, arsenic, lead and zinc but these are less toxic and less distributed. Therefore, the primary source of pollution at the study area could be the landfill operation through the generation of leachate affecting both soil and water / College of Agriculture and Environmental Sciences / M.

It is sincerely hoped that this work will motivate other researchers and in particular my colleagues to do further research in the field of cellphone technology, especially how it can be mapped to enable it to be utilised as evidence in our courts. This research aims to develop the mapping of cellphone technology as an aid in the investigation of crime. The mapping of cellphone technology refers to how cellphone technology can be utilised in crime investigation and in particular how a criminal can be placed at the scene of a crime, as a result of a cellphone call that was either made or received. To place the suspect at the scene of a crime as a result of a call made or received, cellphone records and technology of the relevant cellphone company, as well as present computer programmes can be utilised. Shortly, it can be said that a criminal can geographically be placed within a space some where on this earth. / Criminology and Security Science / M.Tech. (Forensic Investigation)

The present study examined the relationship between parenting styles and the socioemotional adjustment of children at school. A sample size of 90 research participants was selected and included black South African grade I school children aged between 6 and 7 years from single parent households in Pretoria Central. Factor analyses and Cronbach's alphas were determined in order to establish the validity and reliability (alpha= 0.89 and 0. 72 respectively) of the measurement instruments. In general, results were inconsistent with previous findings: The three parenting styles had no direct relationship with children's socio-emotional adjustment at school. Except for two links, non- significant relations between parenting styles and six subscales of socio-emotional adjustment were detected. However, maternal age, preschool attendance and gender of the child interacted in different combinations with four of the six subscales of socio-emotional adjustment. Future studies investigating parenting styles should take account of other areas of adjustment. / Psychology / M.A. (Psychology)

The purpose of the study was to describe the support services available for nurses who care for patients with human immunodeficiency virus / acquired immune-deficiency syndrome (HIV/AIDS) in Pretoria urban pubic hospitals. Problems faced by nurses in HIV/AIDS care support preferences were also investigated. The study was conducted between March and April 2003, using a descriptive design. Respondents comprised eighty-seven (87) nurses who were conveniently selected from five (5) hospitals. Results reveal that support available is inadequate in both quality and coverage of nurses. Other significant findings are inadequate job preparation, shortage of nurses and that nurses prefer to receive support from both within and outside the hospital. It has been recommended that management should work with nurses to design support interventions that match the identified problems/needs. Nurses need to take an active role in caring for themselves and more in-service training opportunities need to be created for nurses. / Health Studies / MA (Health Studies)

The purpose of this study is to describe trauma in the lives of social work students studying at Unisa South Africa. It explores how they describe trauma, what traumatic experiences they have gone through, the effect these experiences had on them, what they did to cope and how these experiences impacted their work as aspiring social workers. A case study was conducted with fourth-level students at Unisa South Africa. The theoretical framework adopted for the research was the person-centred approach. The research involved both focus group interviews and a survey. Both quantitative and qualitative data were generated. Descriptive statistics were used to create a profile of the participants. Qualitative data were analysed using a hermeneutic method. The perceptions of the participants were re-told by the researcher in the form of specific themes that emerged from the data. These themes were discussed and compared with the literature. Implications for the students’ work as social workers were discussed. The study accessed unique aspects of trauma that are grounded in the South African context. The description of trauma that emerged from the research created a new definition of the meaning of trauma. The research discusses the effects of trauma on the emerging professional self of the social work student. Recommendations are made that could be valuable to social work educators wishing to further the personal and professional growth of social work students. The research is also of value to those working with traumatised people. / Social Work / D .Litt. et Phil. (Social Work)

Text in Afrikaans / The research is aimed at the problems surrounding traffic violations and crimes. Firstly, attention is paid to the extent of the problem. Secondly, a theoretical explanation of the problem is offered. This is followed by an exposition of the empirical study which is focused on the perception of road users in the Pretoria municipal area relating to four aspects namely; traffic legislation and traffic law enforcement, traffic violations, adjudication of traffic offences and punishment of traffic offenders. Lastly, the prevention of traffic violations and crimes and specific prevention strategies are conducted and discussed. The research report is concluded with specific conclusions and certain recomendations are offered to deal with the problem. / Die navorsing is toegespits op die problematiek random verkeersoortredings en -misdade.

M.Cur. / This dissertation studies the cause of the high incidence of low birth-mass and how it can be prevented at this specific hospital in Pretoria. A qualitative exploratory and descriptive design was used and a case study used in the context of the specific hospital. The population consisted of mothers of low birth-mass babies and a sample of only 10 mothers was selected. Data was gathered by means of semi-scheduled interviews which were conducted in the language of the subject. There were, however, no opposition from other subjects to be interviewed in English since they understood English. A pilot study was done on only one subject and no major changes were made in the actual study. Permission was obtained from the subjects and they were informed of the objectives of the study, which were: * to detect the reason for low birth-mass babies * * * to prevent the causes to assess the health needs of the patient to be able to improve the health needs by doing strategic planning. The subjects were told that they had the right to refrain from participating - most of them, however, did participate.
