Psychosocial factors contributing to juvenile delinquency in the ZFM-Region, Northern Cape, South Africa

Van Staden, Nataniel January 2015 (has links)
Magister Artium (Social Work) - MA(SW) / The phenomenon juvenile delinquency is an enormous concern for communities in the ZFM district, Northern Cape, South Africa. Juvenile offences have increased since 2010 in this area. From existing theories, it is clear that the causes of this phenomenon are complex and interrelated. Some of these contributing factors are rooted in the character of the delinquent and his or her family. Other factors are peer, community or economic related. Against this background, it is clear that each community/area should be individually assessed concerning its contributing factors as these factors can differ from community to community, individual to individual and family to family. Thus, the research question: What are the psychosocial contributing factors of juvenile delinquency in the ZFM district, Northern Cape, South Africa? The research goal of this study was to determine the psychosocial factors contributing to juvenile delinquency in the ZFM region in the Northern Cape, South Africa. The objectives to arrive to the aim were to explore and describe the psychosocial factors contributing to juvenile delinquency in the ZFM region in the Northern Cape, South Africa and to make recommendations for interventions through probation services by probation officers and the Department of Social Development in the Northern Cape, South Africa. A qualitative approach was used, with an exploratory, descriptive design. Non- probability; purposive sampling was used to select probation officers from the Department of Social Development in the ZFM district in the Northern Cape. These Probation officers have each identified a parent of a juvenile in their caseloads. Because both parents of delinquents and probation officer’s perceptions are shaped by their own context, social constructivism was used as theoretical framework. Data was collected by semi-structured interviews with a checklist. The spiral for data analysis was used to analyse data, which was then clustered in themes, sub- themes and categories. Probation officers, participants identified a range of familial and community contributing factors to juvenile delinquency, and emphasises the interplay between these factors. Their also stressed the issue of parental control and guidance. Participants further indicated that harsh and ineffective parental discipline, lack of parental involvement, family conflict, child abuse and/or neglect and rejection by parents have also been identified as important factors related to delinquent behaviour. Another finding was that single parents, especially single mothers and the lack of a father figure are a great risk factor for juvenile delinquency. Parents also stressed the issue of their lack of control due to peer dependence and the juvenile’s involvement in alcohol and drugs. Probation officers also stressed the lack of parental involvement, continuous communication & parental guidance as some of the important contributing factors of delinquent behaviour amongst children. Parents also indicated a general lack of close relationship amongst family members, as well as emotional insecurity, and the inability to control their children. Both parents and probation officers agreed that peer pressure is a mayor risk factor concerning juvenile delinquency.

Characterization of joints in the Keimoes suite with respect to Namaqua deformation events

Mokoena, Portia Leah January 2013 (has links)
>Magister Scientiae - MSc / The Keimoes Suite is a group of poorly defined granitoids that characterize the Namaqua Front and Foreland zones. There is a lack of knowledge on its content and distribution. A significant amount of work has been done on the geochemical and geochronological aspects of the Keimoes Suite but no structural analysis using a comparison between joint occurrences in the suite and the country rock has been found in the literature. This study provides insight on whether these joints formed as a result of the emplacement and subsequent cooling of the granitoids or whether they are the result of later deformation processes. This was achieved through remote sensing, detailed field mapping and structural analysis of joint data to determine the type of stress regime associated with their deformation. Eleven granitoids of the Keimoes Suite were mapped in the Kakamas-Keimoes area in the Northern Cape, South Africa. Up to four joint sets were mapped and characterized according to orientation, abutting relationship, in-filling material and spacing properties. The orientation analysis revealed two prominent joint sets (NNW and NE) that are consistent throughout the Keimoes Suite granite. However after careful analysis of their abutting relationship it has been concluded that these joints are the youngest joints formed in the Keimoes Suite. The fourth set is the E-W set which does not occur at a wide spread scale. The oldest joint set (NNE) is defined by the quartz and feldspar filling and these joints only occur in the oldest granite of the suite. Field observation revealed shear displacement, forming a conjugate joint set. This conjugate set closes at an acute angle of 60˚ and the joints displace each other. The presence of en echelon sigmoidal veins suggests these joints formed as mode II fractures and that they are tectonic joints. The dominant joint set NNW is parallel to the regional foliation, shear zones and faults which were formed during the D2 deformational vent of the Namaqua Orogeny. This NNW joint set post-dates the D2 deformational event and was formed during the D3 deformational environment of the Namaqua Orogeny. Principal stress analysis of all the joints in the study area suggests a strike-slip environment, which coincides with the D3 deformation event of the Namaqua Natal Province. Even though the country rock and the Keimoes Suite granites were subjected to same stress field during the D3 event, the analysis of principal stresses between the Keimoes Suite granites and the country rock reveals a slight difference in the orientation of the principal stresses. This is caused by the difference in competency between the Keimoes Suite granites and the country rock thus caused the refraction. In conclusion Structural evidence on various members of the Keimoes Suite indicates three episodes of intrusions with respect to the D2 Namaqua deformation event based on foliation and mineral filled joints. The Vaalputs Granite is pre tectonic relative to the main D2 deformation event and the thermal peak M2 metamorphisms, while Louisvale, Kanon Eiland and Klip Kraal Granites are syn-tectonic to these deformation events. The granites that lack foliation are classified as post-tectonic granites and these are the Keboes, Kleinbegin, Gemsbokbult, Colstone and Cnydas Granites as well as the Friesdale Charnockite. However the presence of foliation in some granites suggests that a compressional episode existed for a period of time and ended sometime before the onset of the post-tectonic granites. Therefore the D2 pre-dates the last episode of Keimoes Suite granite emplacement. This study partly validates the work done by previous workers on the Keimoes Suite, although there are some slight differences which are subjected to change. Conclusion can be drawn that this study provided additional insight in the findings of other workers nonetheless also differs with some of their findings regarding the timing of emplacement of the Keimoes Suite.

Risk-based assessment of environmental asbestos contamination in the Northern Cape and North West provinces of South Africa

Jones, Robert Ryan January 2011 (has links)
The commercial mining of asbestos occurred in four Provinces of South Africa (Northern Cape, North West, Limpopo and Mpumalanga). It was initiated in the late 1800's and lasted for over a hundred years into the beginning of this century. As a producer of amphibole asbestos, South Africa far outpaced every other country being responsible for 97% of global production. The last crocidolite mine closed in 1996 and chrysotile in 2002. Anecdotal information concerning environmental contamination as a result of the former mining activities and the improper disposal of mine waste tailings has been reported by a variety of authors. Few comprehensive or systematic surveys have been conducted to date to document this issue and very little quantifiable research has been completed on the communities located in close proximity to the former mine sites to determine the extent of contamination. In 2004-2006 communities were surveyed within the Northern Cape and North West Provinces to determine the extent and severity of environmental contamination. This research developed and applied a methodology to select those communities suspected of environmental contamination, a targeted survey methodology, and a protocol for rapid sample laboratory analysis. A total of 41 communities were initially predicted by the model to be suspected for environmental asbestos contamination. Based on the inclusion of local knowledge, a final 36 communities were selected for a screening-level field assessment, 34 of which were found to contain environmental asbestos contamination at rates ranging from 20 to 100% of the surveyed locations. A total of 1 843 samples of soil and building material were collected in the screening level assessment. One community (Ga-Mopedi) was selected as being representative of the total cohort and a more detailed house to house survey was completed. A total of 1 486 samples were collected during the detailed survey. Results of the detailed survey revealed 26.2% of the homes were contaminated with asbestos containing soil and/or building material. A theoretical quantitative cumulative exposure assessment was developed to estimate the disease burden within the study area population of 126,130 individuals within the surveyed communities resulting in a predicted range of 25-52.4 excess deaths per year from lung cancer and mesothelioma due solely to environmental exposures to asbestos pollution.

Ongeluk volcanism in relation to the Kalahari manganese deposits

Schutte, Sabine Silke 30 November 2011 (has links)
D.Phil. / The Ongeluk Formation is a laterally extensive sequence of ≈2200 Ma tholeiitic basaltic andesites in the upper Griqualand West Sequence of the northern Cape Province. The stratigraphic thickness is about 500 m and the Ongeluk Formation underlies the ore-bearing strata of the Kalahari Manganese Field. The formation comprises massive lavas, pillow lavas and hyaloclastite beds in close association. These rocks were extruded under water in a marginal basin within the continental setting of the Kaapvaal Craton. The Hekpoort Basalt Formation of the Transvaal is magmatically cogenetic with the Ongeluk, having indistinguishable geochemistry and sharing a stratigraphically related hiatus in Cr values. The best age estimate for the two formations is 2193 ± 71 Ma, from Rb-Sr data of two previous workers for Hekpoort samples. The Ongeluk Formation shows a mild "regional" geochemical alteration and a profound "Kalahari" alteration beneath the Kalahari Manganese Field. Geochemical screening was used to reconstruct the magmatic composition from a selected dataset. Three stages in the development of regional alteration are ascribed to sea water-rock interaction at different temperatures, and have distinct geochemical signatures. The pervasive Kalahari alteration is characterised by a purple colouration and the decoupled alteration of alkali and high field strength elements. It is due to the development of major hydrothermal systems close to a volcanic vent which are analogous to modern mid-ocean ridge systems. A multi-system isotopic study showed that most of the isotope systems were modified by sea-floor alteration. The similarity of the 2237 ± 23 Ma Pb-Pb errorchron age with the Rb-Sr Hekpoort age reflects changes in U-Pb ratios with minor changes in Pb isotope ratio. Evidence was found in the Rb-Sr system for a minor disturbance at ≈ 1100 Ma, also reported by previous workers. This event is related to the Namaqua tectogenesis, while no isotopic evidence was found for the enigmatic ≈ 2200 to 1750 Ma Kheis orogeny, regarded as the cause of thrust faulting in the region. A genetic connection between the Ongeluk lava and the Kalahari Manganese deposits was established. The manganese ores contain evidence for both marine and hydrothermal contributions to chemical sedimentation. Negative Ce anomalies characterise an oxygenated sea in which the interaction between global oceanic and continental influences is seen. Heavy rare earth enrichment reflects volcanic hydrothermal exhalations from the Kalahari Ongeluk system. Mass balance calculations show that the entire 9 billion tons of Kalahari Manganese ore could have been derived from the Ongeluk Formation. A new model describing the origin and evolution of the Kalahari Manganese Field places a strong emphasis on the role of the syngenetic hydrothermal exhalation and upgrading.

The impact of precision farming on the profitability of selected maize irrigation farms in the Northern Cape Province

Van Zyl, Stefanus Francois 16 August 2010 (has links)
Maize is the most important grain crop produced in South Africa, serving as a food source for humans and animals, an input provider to other sectors, a source of job creation, a contributor of value added to the national economy, and an earner of foreign exchange. The South African maize industry plays an important role in the South African economy and consequently its role players should be supported to promote the industry. However, since the abolishment of the agricultural marketing boards and the deregulation of South African agriculture, farmers have suddenly found themselves exposed to global competition and a liberalised economy. Maize prices are uncertain and volatile, leading to increased risk. In addition, input prices have increased more rapidly than maize prices in some instances, and since no government protection exists, the cost squeeze effect places many farmers in a financial predicament. In order to mitigate the cost squeeze effect, farmers have started exploring farming methods and strategies that can improve their financial position. Precision farming (PF) is identified as a technological tool that can improve the profitability of a maize farm through higher yields and lower input costs, and can also indirectly assist in the general farm management and financial functions on the farm. The literature indicates that PF has been successfully implemented on various occasions with subsequent benefits, whether financial or qualitative. It could also be a useful tool to improve the profitability of South African maize farmers. Despite its various benefits, PF is associated with high capital expenditures and therefore farmers are reluctant to implement this technology on their farms. However, a PF service system that requires little capital expenditure is implemented by an agribusiness (Griekwaland-Wes Koöperasie) in the Northern Cape Province. Farmers who are part of this program only pay PF service fees that are charged on a perhectare basis. Most of the PF technologies and knowledge are provided by GWK and/or affiliated fertilizer companies, which subsequently mitigate the burden of high capital expenditures. The general objective of the study was to investigate the impact of PF on the profitability of selected maize irrigation farms in the Northern Cape Province. This was achieved by comparing the profitability and risk position of selected farms under a conventional farming (CF) system with the profitability of the same farms when converting to a PF system. The specific objectives of the study were to determine whether PF would generate better profits than CF; to determine whether PF would improve the farmer’s ability to repay his debt and generate an income (thereby improving the financial survivability of the farm); to determine whether PF would improve the debt-to-asset position of the farmer; and to determine whether PF is less risky than CF with respect to net farm income and cash position. The Bureau for Food and Agricultural Policy (BFAP) farm-level model developed by Strauss (2005) proved to be a useful tool to achieve the set objectives, since the BFAP farm-level model is linked with the BFAP sector model, which enables it to accurately analyse the impact of changes in policies and markets at both farm and sector level in South Africa. A positivistic approach was followed in order to answer the question, “What will the likely outcome be?” The model has the capacity to do simulations in both deterministic and stochastic modes. Three maize irrigation farms in the Northern Cape Province were chosen by a panel of agricultural specialists who are accustomed with the irrigation farms and PF system in this province. The farms were analysed by means of the BFAP farm-level model in order to determine the impact of PF on the profitability of each farm. The BFAP baseline of 2008 was used for this purpose. Key input variables were identified and simulated based on the BFAP baseline of 2008, as well as actual data, assumptions regarding PF and CF farming, and reported features and benefits associated with PF. In order to simulate the risk associated with CF and PF through stochastic modelling, correlated probability distributions were assigned to the relevant key input variables by de-trending the historical data of the key input variables. A correlation matrix based on the absolute deviation of a specific variable from its trend was subsequently constructed. Each variable was then simulated by means of a correlated empirical distribution, with 500 model iterations being run for each simulation in order to obtain stable probability distributions. From the results obtained in the study, the conclusion can be drawn that PF not only improves profit margins, but indirectly contributes to improved financial management. Considering the higher profit margins, more cash is at the disposal of the farmer. When this extra cash is again reinvested in the farming business, debt (in terms of production loans and medium- and long term loans) can be repaid more quickly and/or less debt has to be incurred, leading to lower interest payments that in turn further increase profit margins, ultimately improving the debt and cash position of the farm. The results also indicate that the risk position of the participating farms improved significantly with the implementation of PF. It can therefore be concluded that PF could also serve as a valuable risk management tool. From the discussions with the farmers it also became apparent that their overall farm management abilities were improved significantly, due to the informative nature of PF. Based on the results of this study, it can be concluded that the hypothesis as stated in Chapter 1 cannot be rejected. In addition, several other aspects pertaining to PF should be considered. Firstly, the results are applicable to the specific participating farms in the study only, and cannot be attributed to all maize farms in general. Secondly, despite a meticulous process of data verification and validation, the conclusions drawn in the study are based on the quality of the data provided by the stakeholders. Thirdly, factors such as farming operations, management decisions, market, weather and disease conditions might divert from the assumptions made in the study and thereby affect the actual results in future. Fourthly, since the study focuses solely on irrigation farming, a similar study can be conducted on dryland maize farming, since the majority of maize is produced under dryland conditions. Fifthly, the study could serve as a starting point for a comprehensive study on the impact of PF on maize farming throughout South Africa. Sixthly, the study could pave the way for an investigation into using PF as a tool to negotiate lower crop insurance premiums for farmers. Lastly, it would be useful to conduct a similar study on the impact of PF on maize farming where farmers are responsible for the acquisition of their own PF equipment, unlike on the participating farms where no extra capital expenditures were required. This could enable researchers to provide a better answer on the question of costs involved when converting to a PF system, as well as the ideal farm size in terms of economies of scale.

Effectiveness of the information for planning purposes with particular reference to the South African - school administration management systems in John Taolo Gaetsewe District in the Northern Cape

Moyo, Herbert 21 September 2018 (has links)
DEd (Educational Management) / Department of Educational Management / The study investigated the effectiveness of information collected through the SASAMS form in the Department of Basic Education in John Taolo Gaetsewe District in the Northern Cape. The research adopted the two research paradigms, namely, positivism and interpretivism. The research is situated within theories of leadership and organizational effectiveness. The mixed methods research design was used in this study. The study used the survey, interviews, documentary analysis and observation as research methods. The population comprised 171 schools in John Taolo Gaetsewe District. A simple random sampling procedure was employed to get a sample of 30 schools comprised 240 teachers, 3 teacher union representatives and 5 school governing body (SGB) members. Purposive sampling technique was also employed to choose 6 school principals and two EMIS Unit personnel. Qualitative data was generated through interviews, observation and documentary analysis. A survey was administered to obtain quantitative data. Statistical Package for Social Sciences (SPSS) version 24 was used for statistical information. Grounded theory was also employed, and it further provided a descriptive framework which assists in the understanding of a phenomenon that was being investigated. It was established that there were big disparities between enrolment figures declared and the actual ones that prevailed in schools. The study recommends that Circuit District Offices should constantly check and monitor the existence and maintenance of data source documents in schools in order that correct enrolment figures are maintained in schools at all times to enable effective planning processes. The SA-SAMS form should also incorporate a mechanism for detecting ‘ghost personnel’ and ‘ghost learners.’ The study further recommends the linking of HRMS and SA-SAMS tools to play complimentary roles so as to curb malpractices bedeviling the DBE. Additionally, the DBE should consider revising the policy where schools are allowed to factor in a 10% enrolment increase as it creates a good foundation for data falsification by unscrupulous officials. / NRF

Developmental local authorities in small rural towns of the Northern Cape - The case of Victoria west

Nothnagel, Emil January 2004 (has links)
Magister Administrationis - MAdmin / For the last seventeen years I have been actively involved in local government management and I have also been schooled in this academic field. I made this milieu my career as I have an intense yearning to stand in service of the general community, - more specifically the rural communities in South Africa. Practical engagement in this field also taught me that democracy goes hand in hand with urbanisation and, if not countered, the pauperisation of rural districts. The result of this is impoverishment and increasing unemployment.

Investigating the Fauresmith stone tool industry from Pit 4 West at Canteen Kopje, Northern Cape Province, South Africa

Shadrach, Kelita January 2018 (has links)
A dissertation submitted to the Faculty of Science, University of the Witwatersrand, Johannesburg, in fulfilment of the requirements for the degree of Master of Science, Faculty of Science University of the Witwatersrand, Johannesburg 2018 / Canteen Kopje has yielded rare in-situ assemblages of the Fauresmith, a poorly defined industry often associated with the later Acheulean. The Fauresmith contains precocious developments in technology as early as ~0.5 Ma–features which only become widespread in the ensuing Middle Stone Age. The Fauresmith as a regional industry provides insight into technological practices during the period of significant behavioural diversification associated with archaic Homo sapiens. Previous excavations were conducted with relatively low spatial resolution. A new excavation, Pit 4 West, was conducted to investigate the spatial, stratigraphic and contextual association of the Fauresmith horizon in more detail. A multi-disciplinary fineresolution geoarchaeological approach was applied. A nuanced assessment of the Fauresmith’s context was developed, with macroscopic and microscopic analyses allowing for the identification of site formation processes influencing assemblages. The artefact sample size for the site was increased and the presence of diagnostic tools has aided in formally defining the Fauresmith at Canteen Kopje. / XL2019

Transformational leadership : challenges for leaders at the National Institute for Higher Education in the Northern Cape (South Africa)

Laubscher, Teresa 12 1900 (has links)
Thesis (MPhil (Curriculum Studies))--Stellenbosch University, 2008. / Background to the study: The Critical Care nursing programme at the Faculty of Health Sciences (Stellenbosch University) is a one-year programme. The practical component consists of practical procedures and case presentations. Students have limited time available in the clinical areas to reach competency in the practical skills. Students tend to use the majority of the clinical teaching time available to reach competency in these practical procedures, rather than discussing the patient and learning the skills to integrate and understand the patient’s condition and treatment, which they can acquire by doing case presentations. The end result of this misuse of clinical contact time is that some of the students, by the end of their programme, still have difficulty to integrate a patient’s diagnosis and treatment regime, although they have managed to complete the expected practical procedures. Summary of the work: A case study design was used. I wanted to investigate whether one could make use of simulation and the Clinical Skills Centre (CSC) to complete the majority of the practical procedures so that more time would be available in the clinical areas for the students to do case presentations. The study focuses on describing how the tutors and students involved experienced the use of simulation, as well as how it impacted on the available teaching time in the clinical areas. Conclusions and recommendations: Some of the most important issues that were highlighted in the study and needs to be mentioned are the following: · The students highly valued supervision by a Critical Care tutor when practising their skills in the CSC. · Students indicated that they valued the opportunity to practise some of the more risky procedures in simulation, because it presents no risk to patients. · Case presentations seem important to be added to the CSC’s practical sessions in order to attempt making the practical simulated scenarios even more realistic. · The teaching at the bedside in the clinical areas used to be done somewhat ad hoc. With the teaching in the CSC now being much more structured, this necessitates the teaching at the bedside to be revisited and to be structured to a certain extent. Summary of the results: The information obtained from the Critical Care tutors and the students indicated that these two groups were largely in agreement that simulation seems to be valuable and can effectively be used in a Critical Care nursing programme.
