The fluvio-lacustrine rocks of the Beaufort Group, South Africa have long been known for their tetrapod fossil record, which is the richest and most complete Middle Permian to Middle Triassic record for any terrestrial sequence in the world. The abundance of fossil material has enabled the Beaufort Group to be biostratigraphically subdivided into between 8 and 10 tetrapod assemblage zones, of which the lowest three (Eodicynodon, Tapinocephalus and Pristerognathus) are attributed to the Middle Permian. These lower assemblage zones record the earliest therapsiddominated faunas and, because they were recorded during a largely uninterrupted period of deposition, make the Beaufort Group the only place in the world where biodiversity change through the terrestrial Middle Permian can be effectively studied. In the last two decades, much interest has focused on an extinction of marine invertebrates at or close to the end of the Middle Permian (Guadalupian epoch), but the existence of a concurrent extinction in the terrestrial realm is contentious. The Beaufort Group is already well known to record the Permo-Triassic Mass Extinction but it also records an earlier extinction at the top of the Tapinocephalus Assemblage Zone (AZ). This extinction is very poorly understood but recent radiometric dates for many Permian assemblage zones of the Beaufort Group have confirmed a Middle Permian age for Eodicynodon, Tapinocephalus and Pristerognathus assemblage zones and suggest that the end-Tapinocephalus AZ extinction may coincide with the marine extinctions. A recently produced GIS database that accommodates all Beaufort Group fossil material curated in South Africa formed the basis on which the stratigraphic range of individual specimens was calculated. To put the fossil localities in a stratigraphic context, lithostratigraphic information was retrieved from the literature and extensive fieldwork was conducted, which measured stratigraphic sections in key areas and traced the surface outcrop of lithostratigraphic units. In order to compensate for lateral variations in lithostratigraphy, the basin was split into sectors, each represented by a stratigraphic section. The stratigraphic ranges of fossil specimens and, subsequently, of genera and families could then be calculated and a workable biostratigraphic subdivision of the Middle Permian Beaufort Group proposed. The Abrahamskraal Formation, which forms the majority of the Middle Permian Beaufort sequence, can be divided into six lithostratigraphic members based on the occurrence of sandstone ‘packages’. These members were traced laterally across the Basin and their correspondence with fining-upwards cycles was refined and correlated with the newly defined biostratigraphic units. This refined two-pronged stratigraphic subdivision allowed the recognition of a waning period of subsidence in the proximal sector of the Karoo Basin during the Middle Permian. Stratigraphic ranges of individual genera were found to be far more heterogeneous than previously recognised. Dicynodont genera are useful biostratigraphic indicators due to their relative abundance and well-defined stratigraphic ranges, while dinocephalians and pareiasaurs are clustered in the upper part of the Abrahamskraal Formation. The stratigraphic range of Eodicynodon extends further up in the Abrahamskraal Formation than was previously recognised. The Tapinocephalus AZ is restricted to approximately the upper fifth of the Abrahamskraal Formation and is characterised by advanced tapinocephalid dinocephalians and the pareiasaur Bradysaurus. Between these two biozones is a stratigraphic interval dubbed the mid- Abrahamskraal Formation Transition Zone, where both Eodicynodon and advanced tapinocephalids coexisted. A 75 % loss of generic diversity occurred between the upper Tapinocephalus AZ and the base of the Pristerognathus AZ, which corresponds to a stratigraphic interval between the mid-Karelskraal Member of the Abrahamskraal Formation and the mid- Poortjie Member of the Teekloof Formation. Several taxa that survive the end- Tapinocephalus AZ extinction, and are relatively common in the overlying Pristerognathus AZ (scylacosaurid therocephalians, the dicynodont genus Eosimops and the parareptile Eunotosaurus), all became extinct in the upper Poortjie Member at a time when generic originations are increasing. This suggests a second wave of extinctions in a similar fashion to that recorded at the Permo-Triassic boundary.

A research report submitted to the Faculty of Humanities, University of the Witwatersrand, Johannesburg in partial fulfilment of the requirements for the degree of Masters in Community-based Counselling Psychology on 15 March 2016 / Despite the often publicised occurrence of residential robberies being accompanied with additional forms of violence there is a limited amount of research exploring these forms of intersecting violence, specifically within the South African context. The latest statistics released by the South African Police Service (2015) indicate that residential robberies are continuing to increase. The co-occurrence of rape in such residential robberies is under-studied. Therefore, the aim of this study was to explore and describe a profile of residential robberies that are accompanied by rape in Gauteng, South Africa between 2002 and 2012. This was done by exploring the temporal, sociodemographic and situational factors related to reported instances of this crime. The study consisted of cases obtained by the Crime Administration System (CAS). The study focused specifically on instances of reported residential robbery, in Gauteng. Overall there were 68178 cases analysed, with 1104 cases containing instances of reported co-occurring rape. The initial descriptive results indicated that specific variables significantly influence the co-occurrence of rape during a residential robbery. Whereby, there has been a significant increase in the proportion of rapes co-occurring within the 2002 to 2012 period Additionally, binary logistic regression analysis showed that Black females between the ages of 12 and 17 years are the demographic group most at risk when other situational factor are additionally present. Other findings of the regression indicate that there is an increased risk of a rape co-occurring during the residential robbery; over the weekend, between the hours of 00:00 and 06:59 and when no firearm is used as the method of entry or during the residential robbery. Overall, the study present significant findings related to this specific co-occurring crime and a number of areas that can be further explored in relation to the co-occurrence of rape during residential robbery and other forms of co-occurring violence, specifically in the context of South Africa

A research report submitted in partial fulfilment of the requirements for a Master of Arts degree in the Faculty of Arts, University of the Witwatersrand, Johannesburg. / This report is an exploratory discussion of the prospects for private sector investment in development initiatives. Based on a set of structured and unstructured interviews, a press review and a survey of the relevant literature, the report paints to a growth in the areas of commonality between the worlds of investment and development, in that there is increasing recogniticm of the need to direct resources to South Africa's poor at the same time as market forces are starting to play an enlarged role in development. The report argues however, that the social context in which investors are 'embedded' is very different from that of development practitioners, leading to a situation in which development projects are seen as risky investments. The difficulty experienced by private investors in understanding the world of development is identified by the report as the single largest obstacle to private sector investment in development. The report draws the conclusion that mediating institutions are required to structure relationships between development agents and investors. / Andrew Chakane 2018

This dissertation givens and analytical overview of the research and recovery actions for the Orange-bellied Parrot and the Kangaroo Island Glossy Black-Cockatoo and evaluates the successful practices and those which have failed. This research shows that new recovery action initiatives can still be found and that not all recommendations in recovery plans are followed, which impairs the efficiency of the recovery efforts. It concludes that a successful recovery effort of these two bird species lies in continued research, a serious compliance with the recommendations made by recovery plans and by further environmental education in society.
