The main focus of this dissertation was to evaluate the evidential value of crime scene investigation in child rape cases. There are two kinds of crime scenes that needed to be processed in sexual crimes. Firstly is the location of occurrence and secondly is the victim's body. The crime scene is in any crime the major source of information if correctly approach, but even more so in a child rape investigations. A few crimes rely so heavily upon physical evidence as does the crime of rape. It is therefore essential that all rape investigators have first-class knowledge of proper crime scene investigation methods and techniques. Since crime scenes not properly protected or process may fail the investigation in court and as a result see the suspect acquitted. The following physical evidence could link and assist the investigator to individualise the suspect during thorough crime scene investigation; body fluids such as semen, blood, saliva. Other evidence of physical nature commonly found at crime scenes includes fingerprints, footprints (impression evidence); soil evidence, hair evidence, and anything in general handled or left behind by the rapist at the crime scene. This dissertation strives to provide the Investigator with answers on, how, where, and when to process the crime scene. / Criminology and Security Science / M.Tech. (Forensic Investigation)

This dissertation focuses on investigating the relationship between organisational culture and employee engagement in a Public Service department. In this quantitative study, undertaken in a South African Public Service department (North West province), dimensions of organisational culture (measured by the South African Culture Instrument) were correlated with the dimensions of employee engagement (measured by the South African Engagement Measurement). Correlational analyses revealed a statistically significant positive relationship between each of the dimensions of organisational culture and employee engagement, respectively. ANOVA statistical technique was used to determine whether significant differences exist between groups. Regression analyses revealed that leadership, employee needs and objectives, vision and mission, management processes and internal relationships would predict employee engagement. Leadership made the most significant predictor of employee engagement. The means to achieve objectives dimension showed no effect in predicting employee engagement. This indicates that positive perceptions of organisational culture are likely to be related to higher levels of employee engagement. / Industrial and Organisational Psychology / M.Com.

Against the background of evidence that HIV-AIDS has had and continues to have an enormous impact on all South African schools, a need has arisen for HIV -AIDS policies and programmes to be effectively implemented in all schools. In this study, a qualitative methodology was used to evaluate policy implementation in the North West province. Data was gathered by means of field notes, observation and interviews with management and educators. The study found that although principals and educators are knowledgeable about HIV -AIDS, there is a tendency to discriminate against infected educators, particularly in terms of educator workload. This study also revealed that educators fear being accidentally exposed to HIV -AIDS infected blood, despite the guidelines given in the National HIV -AIDS policy and the availability of emergency first aid kits. The key thought emerging from this study is that not all schools are able to deal effectively with HIV -AIDS and that schools urgently need to plan or implement their own policies in this regard. School-based HIV-AIDS policies can only be successful if they take cognisance of local contextual issues and involve the three spheres of influence in the lives of educators and learners, namely, the sphere of the school, the sphere of family life and the sphere of the community. / Sociology / M.A.(Social and Behavioural Studies in HIV-AIDS)

The escalating figures of unemployment and poverty in South Africa are posing a threat to the nuclear family. The deteriorating conditions in the home environment, particularly regarding material provision, has led to an increase in disadvantaged home environments. The investigation in this study focused mainly on the self-concepts of adolescents from disadvantaged home environments. The aim of the research was to see how the home environment influences the self-concept of an adolescent in disadvantaged areas. The literature study showed that factors such as unemployment, poverty, low socio-economic background, single parenthood, absent parents, parents' level of literacy and parenting styles were associated with disadvantaged home environments. With regard to the self-concept the researcher probed the physical, emotional, social, academic and general self-concepts. An empirical investigation was undertaken regarding grade 9 and 11 learners in Hebron in the North West Province. A structured questionnaire was developed focusing on home environment and self-concept. By using Pearson's correlation, ANOVA and Tukey's t-test, findings indicated that there is a significant relationship between home environment and the self-concept. The adolescent's emotional self-concept is affected by religion, supervision at home (parent or guardian) and the number of siblings in the family. Moreover, girls had a better social self-concept than boys. On the whole the physical, academic, social and general self-concepts were not affected by religion, number of siblings in the family and different kinds of supervision. With regard to the physical self-concept it was found that it differed with age. Therefore, the educators who facilitate Life Orientation in the General Education and Training (GET) band and Life Skills in the Further Education and Training (FET) band should assist children who come from disadvantaged home environments by applying intervention strategies suggested by the researcher in this study to foster positive self-concepts in adolescents. Positive self-concepts are key factors for successful learning, general behavioural patterns and high participation in school activities. Upgrading of educators is also recommended so that they are fully equipped to assist a learner who is from a deprived home environment. / Educational Studies / D.Ed.(Psychology of Education))

D.Ed. (Psychology of Education) / Although the human immuno-deficiency virus (HIV) and acquired immuno-deficiency syndrome (AIDS) is still very much a silent issue in South Africa, the AIDS pandemic has become a public problem which is threatening to a significant proportion of the population of South Africa (Heartbeat 2002:1; Kaseke and Gumbo 2001:53). HIV infections are on the rise and people are dying every day of AIDS related diseases (Msomi, 2000:8). Thus, the overall aim of this research was to determine how the HIV/AIDS orphans’/vulnerable children’ psychosocial status is affected by the HIV/AIDS disease. The study was conducted in the Bojanala Region of the North West Province. A purposeful sampling was used because four (4) schools were suggested by the Department of Social Services in the Rustenburg Area due to their high populace with HIV/AIDS orphans. The other four (4) schools were suggested by the Auxiliary Services Division in the Bojanala Region of Education. The literature revealed that failure on part of the parent, guardian and/or teachers to meet the psychological needs of the child at a certain stage in his/her development may result in personality disorders, which can become a potential danger and a source of unhappiness to the individual him/herself (cf. 2.5). Furthermore, it was evident from the literature that chronic parental illness may have a traumatic effect on young children because both parents may neglect a child (cf. 4.2). The literature also revealed that children should not be viewed as passive recipients of assistance, but as active participants who play a key role in the development of responses to the HIV/AIDS pandemic. Receiving quality services is a right and a need not only of AIDS orphans, but also of all children (cf. 4.6). From the quantitative data analysis, the following findings emerged, that HIV/AIDS orphans/vulnerable children are optimistic about their future. Children do not blame themselves for their parents’ death. Arising from this research certain conclusions were drawn, recommendations were made and areas for possible future research were suggested. / Teacher Education

Thesis (MScConEcol (Conservation Ecology and Entomology))--University of Stellenbosch, 2011. / ENGLISH ABSTRACT: I evaluated the impact of Prosopis invasion and clearing on ecological structure, function and agricultural productivity in heavily grazed Nama Karoo rangeland on two sheep farms near the town of Beaufort West in the Western Cape Province of South Africa. My aims were to (1) determine the effects of invasion and clearing on rangeland vegetation composition, diversity (alien and indigenous species richness) and structure (alien and indigenous species cover), soil vegetation cover (plant canopy and basal cover) and agricultural productivity (grazing capacity), (2) describe the vegetation processes that underlay the invasion and clearing impacts and (3) evaluate the success of clearing in facilitating unaided restoration of ecological structure, function and agricultural productivity in formerly invaded rangeland. I hypothesised that invasion would significantly change rangeland vegetation composition and structure, leading to greater alien species richness and cover and lower indigenous species richness and cover while clearing would lead to lower alien species diversity and cover and greater indigenous species richness and cover. In addition I hypothesized that invasion would reduce rangeland plant canopy and basal cover and grazing capacity while clearing would substantially increase them. Finally I predicted that vegetation composition, alien and indigenous species cover and richness, plant canopy and basal cover and grazing capacity would revert to pre-invasion status and levels within four to six years of clearing. My results suggest that in heavily grazed Nama Karoo rangeland Prosopis invasion (~15 percent canopy cover) and clearing can significantly change rangeland vegetation composition, with invasion leading to greater alien species cover and lower indigenous species richness, while clearing leads to lower alien species richness and cover and greater indigenous species richness and cover. However invasion seems to have no effect on alien species richness and overall indigenous species cover. Clearing appears to facilitate the spontaneous restoration of alien species cover and indigenous species richness within four to six years but not species composition, alien species richness and indigenous species cover. In addition my results also indicate that Prosopis invasion can lower rangeland plant canopy and basal cover and grazing capacity while clearing, even under heavy grazing, can substantially raise them. Clearing however does not seem to facilitate the restoration of rangeland plant canopy and basal cover and grazing capacity to pre-invasion levels within four to six years after clearing. / AFRIKAANSE OPSOMMING: Ek het die impak van Prosopis indringing en verwydering van indringers op ekologiese struktuur, funksie en landbou produktiwiteit in ‘n swaar beweide Nama Karoo gebied op twee skaapplase naby Beaufort-Wes in die Wes-Kaap provinsie van Suid-Afrika geëvalueer. My doelwitte was om (1) te bepaal wat die gevolge van die indringing en verwydering van indringers op die natuurlike plantegroei samestelling, diversiteit (uitheemse en inheemse spesiesrykheid) en struktuur (uitheemse en inheemse spesies bedekking) sal wees, sowel as die effek op plantegroei bedekking (kroon en basalebedekking) en landbou produktiwiteit (weidingkapasiteit), (2) die plantegroei prosesse te beskryf wat onderliggend deur die impakte van indringing en verwydering van indringers veroorsaak word, en (3) die sukses van die verwydering van indringers te evalueer deur die fasilitering van blote restorasie van ekologiese struktuur en funksie en landbou produktiwiteit in voorheen ingedringde gebiede. My hipotese is dat indringing ‘n aansienlike verandering in natuurlike plantegroeisamestelling en struktuur sal veroorsaak, wat sal lei tot groter uitheemse spesiesrykheid en bedekking met minder inheemse spesiesrykheid en bedekking, terwyl die verwydering van indringers sou lei tot minder uitheemse spesie diversiteit en bedekking met 'n groter inheemse spesiesrykheid en bedekking. Verder vermoed ek dat indringing die natuurlike kroon- en basalebedekking en weidingkapasiteit sal verminder, terwyl die verwydering van indringers dit aansienlik sal verhoog. Ten slotte voorspel ek dat plantegroei samestelling, uitheemse en inheemse spesiesbedekking en -rykheid, kroon- en basalebedekking en weidingkapasiteit sou terugkeer na voor-indringing status en vlakke binne vier tot ses jaar na die verwydering van indringers. My resultate daarop dat die indringing van Prosopis (~ 15 persent kroonbedekking) en die verwydering van indringers in swaar beweide Nama Karoo gebiede ‘n aansienlike verandering in die gebied se natuurlike plantegroei samestelling toon, waar indringing gelei het tot groter uitheemse spesiesbedekking en minder inheemse spesiesrykheid, terwyl die verwydering van indringers lei tot minder uitheemse spesiesrykheid en groter inheemse spesiesrykheid en - bedekking. Dit lyk egter of indringing geen effek op uitheemse spesiesrykheid en algehele inheemse spesiesbedekking het nie. Die verwydering van indringers blyk om die spontane herstel van indringerbedekking en inheemse spesiesrykheid binne vier tot ses jaar te fasiliteer, maar nie spesiesamestelling, uitheemse spesiesrykheid of inheemse spesiesbedekking nie. Benewens dui my resultate ook aan dat Prosopis indringing die natuurlike kroon- en basalebedekking sowel as weidingskapasiteit verlaag, terwyl die verwydering van indringers, selfs onder swaar beweiding, die bedekking aansienlik kan verhoog. Verwydering van indringers lyk egter nie asof dit die herstel van die gebied se natuurlike kroon- en basalebedekking en weidingkapasiteit na voor-indringing vlakke toe kan fasiliteer binne vier tot ses jaar na die verwydering van indringers nie.

[Truncated abstract] The southwest of Western Australia is an intraplate area classified as a stable continental region. It comprises predominantly Archaean and Proterozoic geology and has generally subdued topography. The region currently experiences significant seismicity in the Southwest Seismic Zone (SWSZ), which is one of the most seismically active areas in Australia and is thought to represent the highest seismic hazard of the region. In recent years, numerous scarps, potentially related to large palaeoearthquakes have been recognised not only within the SWSZ, but also in a broader region of the southwest of Australia. Palaeoseismological investigations of two of these scarps, the Dumbleyung and the Lort River scarps, confirm their association with surface-rupturing palaeoearthquakes and indicate events with likely maximum magnitudes of ~Mw 7.0 on faults of low to medium slip rates. Two trenches across the Dumbleyung Fault scarp revealed a thrust fault in alluvial sediments with two associated earthquakes in the last ca 24-60 ka. A possible Holocene age was recognised for the last recorded earthquake event exposed in these trenches. Two trenches across the Lort River Scarp show that this feature results from thrust faulting in the weathered gneissic country rock. These trenches exposed evidence of two events in the last ca 35 ka, with a likely late Pleistocene age for the last earthquake. On both sites, the earthquakes are interpreted as associated with the last phase of fault activity, which was likely been preceded by a long period of quiescence. Assessment of the earthquake hazard associated with large earthquakes at the Dumbleyung and Lort River Faults resulted in calculated peak ground accelerations of up to 2 g in the near-fault fields. Such earthquakes would significantly affect nearby towns such as Dumbleyung, Wagin, Katanning, and Esperance, but they are unlikely to cause any significant damage in Perth. The palaeoseismological investigations show that the earthquake activity in the southwest of Western Australia is not only confined to the SWSZ, as it has been considered in previous assessments of the seismic hazard, but that there is also potential for strong earthquakes across much of the region. The seismicity in the southwest of Western Australia appears to be transient and migratory. This is suggested by the lack of local relief associated with places of current seismicity and fault scarps, the widespread distribution of the fault scarps across the region, the increase in seismicity in the SWSZ following strong recent events, and the apparent long periods of earthquake recurrence at fault sites. Accordingly, the current seismicity in the SWSZ is inferred to be transient and probably associated with stress changes produced by the recent earthquakes. '...' This uplift could be associated with dynamic topography effects resulting from processes along the plate margins. The uplift is probably enhanced by a flexural response of the lithosphere to local differential loads and density contrast along the southern margin, a mechanism that may also help explain the occurrence of some earthquake activity. The results from this study, complemented by additional palaeoseismological studies must be included in future probabilistic assessments of the seismic hazard of the southwest of Western Australia.
