A thesis submitted to the Wits School of Education, Faculty of Humanities, University of the Witwatersrand in fulfilment of the requirements for the Degree of Master of Education Johannesburg, 2016 / Homework has become an integral part of the school curriculum and policy, yet the evidence base for its inclusion is contestable and inconclusive. In South Africa homework is a statutory requirement for all schools (DoE, 1998) and nearly all schools have included it in the standard process of learning. The main argument of this research is that despite its adoption and application in schools, the justification for its use is barely understood. Its application in schools seemed to be based on anecdotal evidence. Considering there is very little empirical data that demonstrates the extent of the utilisation of evidence around homework-based decisions in South African schools, this study intends to establish what sources of evidence are available to schools to support decision-making around the key policy matters, perceptions, implementation, benefits and challenges associated with the applications of homework in school. Forty educators and two HoDs were recruited for the questionnaires and interviews respectively. The selected educators represented certain types of characteristics and had comparative teaching styles. This was done because some teachers give assignments that combine learning and ecstasy while others give homework that upset the whole process, therefore the administration of homework is different. Random sampling was used in selecting the educators and purposive sampling was used only in selecting the HoDs and this was done by selecting participants with certain characteristics to provide the best information to address the purpose of the research. The researcher concludes that most educators claimed they receive very little support from the education department in terms of homework issues. The study suggests there is a correlation between homework and achievement, but is not adequate to conclude beyond reasonable doubt that it is indeed the case. However, the study can argue there are some benefits beyond academic acquisition of knowledge. By contrast, the study also highlights that homework marginalises economically disadvantaged students who find it difficult to complete homework tasks due to environmental issues. In concluding; the study suggests that for homework to be effective, homework implementers need to undertake critical research in order to understand the short comings of homework incompletion.

A thesis submitted to the Faculty of Humanities, University of the Witwatersrand, Johannesburg, in fulfilment of the requirements of the degree of Doctor of philosophy. March 2016. / The use of found objects is evident in a range of contemporary artmaking practices. The use of found objects can, however, no longer be understood as a rupture from tradition as they were in the early decades of the twentieth century when they were first used by Picasso and later by Duchamp, because found objects have become part of a longer genealogy in art making. A new approach is needed in order to understand the significance of the use of found objects in contemporary art. This study explores the significance of the use of found objects in selected contemporary South African artworks in order to move beyond an understanding of the use of found objects as the anti-art gestures like those of the historical and neo-avant-gardes. I propose that a shift in focus, from the idea of the found objects as anti-art, to an exploration of the changing ontological status of the found object as it moves through different social fields is one such new approach. Chapter one introduces the study, while chapter two outlines the research methods and theoretical frameworks used. Chapter three explores the meanings that objects accrue in everyday practices, while chapter four focussed on the difference between artworks and more quotidian objects. Pursuing the question of the manner in which the ontological status of the object shifts as it enters into and becomes part of the field of exhibition, chapter five considers the ways in which meanings are constructed for objects in the field of exhibition through the conventions of display. I explore the ways in which artists make use of or invert these conventions as a means of challenging the field of exhibition. Acknowledging that the objects are also active agents within this process, in chapter six I explore the manner in which the materiality of found objects contributes to the meaning of the artworks, and by extension, I consider what new possibilities of meaning a focus on the materiality yields. In the final chapter, I use the concept of the everyday to draw the themes that have emerged throughout this study together. I conclude by situating the contemporary South African art practices within the genealogy of the avant-garde.

This qualitative study explores the maternal experiences of black South African mothers living in a township in Johannesburg. Extensive research and literature has begun to address the experiences of motherhood from the mother’s perspective, however research into the experiences of black mothers is still limited. In the past psychological literature on South African motherhood tended to focus on at-risk mothers and children rather than exploring their personal narratives. This study presents the narratives of six black mothers living in Alexandra township in Johannesburg, Gauteng. The six mothers participated in individual, semi-structured interviews. The data was analysed using the narrative analysis technique. The analysis provides insight into the personal experiences of motherhood and highlights the central narratives that these mothers told. What emerged is that mothers have individual and unique stories to tell, their stories about becoming a mother are central to their narratives on motherhood and the context in which mothers mother is pivotal in shaping their mothering experiences.

A thesis submitted to the Faculty of Science, University of the Witwatersrand, Johannesburg, in fulfilment of the requirements for the degree of Doctor of Philosophy. 25 October 2016 in Johannesburg, South Africa. / Ecosystem services, nature’s benefit to people, contribute to human well-being. Extensive reliance on, and unsustainable use of, natural resources is typical of the rural poor in developing countries and can lead to ecosystem degradation, decreased ecosystem service provision, and increased vulnerabilities of rural populations. Most ecosystem services are intangible or difficult to quantify, but fuelwood provisioning can be measured directly and can serve as a proxy for the status of other ecosystem services (e.g. aesthetic and spiritual services, nutrient cycling, carbon sequestration). South African rural communities have a high reliance on fuelwood despite extensive access to electricity. Within this context, live wood harvesting occurring around rural settlements in increasing amounts has been deemed unsustainable. However, the ‘fuelwood crisis’ of the 1970s, and subsequent predictions of woodland collapse through fuelwood supply-demand models, has still not occurred despite substantial population growth in developing countries. Hypothesised reasons for modelled supply-demand mismatches are based on underestimation of fuelwood supply and woodland regeneration, as well as overestimation of fuelwood demand by discounting behavioural adaptability of users. It is likely that the spatial configuration of fuelwood use allows for the co-adaptability of both humans and ecosystems. A lack of understanding of the spatial configuration of these social-ecological dynamics limits our insights into current and future adaptive responses and thus, the degree of sustainability. This thesis aimed to assess woody biomass stocks and vertical structure changes, as a proxy for provisioning ecosystem services, in a spatially and temporally explicit manner, to describe the status and impact of wood extraction in semi-arid, savanna communal lands. Using repeat, airborne light detection and ranging (LiDAR) data from 2008 and 2012, we surveyed three-dimensional woodland structure in Bushbuckridge Municipality communal lands – the grazing and harvesting areas for densely populated rural settlements in former Apartheid ‘homelands’ in South Africa. Woody biomass in 2008 ranged from 9 Mg ha-1 on gabbro geology to 27 Mg ha-1 on granitic geology. Land-use pressure was associated with compensatory regrowth of savanna tree species through post-harvest coppice in the 1-3m height class. Woody biomass increased at all sites, contrary to previous fuelwood models of the area. Change detection in the vertical canopy structure revealed that biomass increases were almost solely attributable to the 1-3m and 3-5m height classes. These changes were exacerbated by wood extraction intensity in the communal lands – the communal land with the highest wood extraction pressure experienced the greatest biomass increases, likely a strong regrowth response to high harvesting levels. Within communal lands, areas closest to roads and settlements experienced substantial biomass increases as a result of shrub level gains. This relationship was mediated by the usage gradient – the greater the wood extraction pressure on the communal land, the larger and more spatially coalesced the ‘hotspots’ of shrub-level increases were in relation to ease of access to the communal land. However, biomass increases are not necessarily indicative of woodland recovery, as shrub-level increases were coupled with losses of trees >3m in height. To explore these tall tree dynamics further, we tracked >450 000 individual tree canopies over two years over contrasting landscapes – a private reserve containing elephants, two communal lands under different wood extraction pressures, and a nature reserve fenced off from both elephants and humans. Humans are considerable drivers of treefall (defined here as a ≥75% reduction in the maximum height of each tree canopy) in communal lands. Humanmediated biennial treefall rates were 2-3.5 fold higher than the background treefall rate of 1.5% treefall ha-1 (in the control site – the reserve containing neither elephants nor humans). Elephant-mediated treefall was five fold higher than the background rate. Rate and spatial patterns of treefall were mediated by geology and surface water provision in the elephantutilised site where relative treefall was higher on nutrient-rich geology, and intense treefall hotspots occurred around permanent water points. Human-mediated rates and spatial patterns of treefall were influenced by settlement and crop-land expansion, as well as ease of access to communal lands. Frequent fires facilitated the persistence of trees >3m in height, but was associated with height loss in trees <3m. The combined loss of large trees and gain in shrubs could result in a structurally simple landscape with reduced functional capacity. Shrub-level increases in the communal lands are likely an interactive combination of newly established woody encroachers and strong coppice regrowth in harvested species. The more intensely used the communal land, the greater the bush thickening and the stronger the relationship between biomass gains and structural changes in the lowest height classes. The exacerbation of bush thickening in natural resource-dependent communities has critical implications for ecosystem service provision. There is potential for coppice regrowth to provide fuelwood to communities using ‘tree thinning’ programmes, but there is a lack of data on the quantity and quality of the regrowth, as well as the sustainability of coppice, the impacts of different harvesting methods, and the potential feedbacks with changing climate and CO2 fertilisation. Woody resource spatial distribution in communal lands is centred around settlement-level wood extraction pressure, as well as natural resource accessibility in the woodlands. In highly utilised areas, woodland regenerative capacity has been underestimated. Additionally, natural resource extraction is still highly localised, even at the communal land scale, with major structural changes occurring around the periphery or close to existing infrastructure. However, it is these underrated coupled adaptive responses in social-ecological systems that explain the failure of fuelwood supply-demand models’ predictive abilities. Nevertheless, loss of large trees in the landscape and the persistence of ‘functionally juvenile’ coppice stands will have implications for seedling production and establishment in the landscape with repercussions for the future population structure and ecosystem service provision. I discuss the implications of increased natural resource reliance in an African development context and the positive feedback between rural poverty and environmental impoverishment. Potential constraints to the data are unpacked, together with opportunities for further research in this area. / LG2017

A dissertation submitted to the Faculty of Arts, University of the Witwatersrand, Johannesburg, in fulfilment of the requirements for the degree of Master of Arts. / This research report examines the experiences of a group of women-soldiers serving in the South African National Defence Force (SANDF) in relation to two major sociological concerns. The first concern is the South African transition and the establishment of the SANDF, and the second is gender issues within the military. There is little literature concerning women-soldiers in relation to the establishment of the SANDF. In addition, the iiterature on women and militarism suggests that there is no consensus amongst women around key questions regarding the military. Therefore, researching the experiences of'a group of women-soldiers required the use of research methods which would enable a free flow of information by the respondents. This particular group of research subjects was identified through the quota sampling technique. The group represented a large variety of social identities and backgrounds. The informants were interviewed primarily through structured in-depth interviews. The central finding of this research is that the informants had various experiences according to different sociological characteristics, such as race, previous military service, or marital status. In relation to the transition and the establishment of the SANDF, military experience and race were found to be the most important factors in shaping the respondents' experiences. In this regard, I have argued that the SANDF reflects the former SADF Concerning gender issues within the military, marital status appeared as the most relevant factor. Considering this, it is suggested that the social responsibilities attached to wifehood and motherhood influence women toward traditional female domains in the workplace. / Andrew Chakane 2019

A dissertation submitted to the Faculty of Arts, University of tho Witwatersrand, Johannesburg, for the Degree of Mastel' of Arts. Johannesburg 1991 / The industrial supervisor is the classical example of the person in the middle or the 'marginal person' Placed between management and the workforce, supervisors encounter conflicting expectations and demands. For the black supervisor in South African industry, these problems are exacerbated, typically having been promoted from the ranks and operating at an essentially white management, black workforce interface. Previous researchers have discussed the dysfunctional consequences faced by these people and, further, have alluded to the possible relationship between this and supervisors' dual loyaltles. This research examines the marginality of black supervisors and how this relates to their possible dual commitment. Towards this end, a psychometrically sound measure of psychological marginality was constructed, following which an empirical investigation was undertaken to investigate the relationship between black supervisors' psychological marginality and their dual allegiances. Factor analytical techniques revealed that black supervisor's marginality comprises two variables; namely, management marginality and worker marginality. The relationships between both marginality variables and levels of organisational commitment, union commitment and dual commitment were not significant. This suggests that the management and worker marginality experienced among black supervisors is not related to dual commitment, unilateral commitment and alienation. Implications of these findings for theory and practice are discussed and directions for future research provided. The primary shortcoming of the study was small sample sizes as a result of the sensitive nature of the subject. However, this was mediated by the rigorous methodology adopted throughout.

In South Africa, indigenous plant species are used and traded for traditional medicine (muthi) and so are alien plant species. A literature review of 40 previous studies and survey work at various outlets, including muthi markets and muthi shops in Johannesburg, Durban and Pretoria, found that 320 alien plant species are used and/or sold for traditional medicine in South Africa. Fifty three of the 320 species were found to have weed and/or invader status. Surveys at Faraday and Warwick muthi markets in Johannesburg and Durban respectively as well as muthi shops in Johannesburg, Durban and Pretoria were conducted from October 2010 to February 2011. The following aspects regarding the plant material traded were recorded: the differences in the number of volumes traded; the differences in the number of alien species sold in the markets and shops (and also in Indian and Black-owned shops); the source and origins of these and the viability of propagules sold in the muthi trade. The surveys found that 49 alien plant species were sold and approximately 87 x 50kg-size bags of alien plant material was present in the markets and shops during the time of the survey. Muthi shops sold more than double the number of alien plant species than were sold in the markets and the same result was found for Indian versus Black-owned shops. Alien species were either harvested in South Africa, predominantly in KwaZulu-Natal (KZN), or imported from India. Indian-owned muthi shops sold more species imported from India than alien species that were naturalised and harvested in South Africa. In contrast, the majority of alien species sold at markets and Black-owned shops were harvested in KZN. Viability tests found that 24% of alien plant species sold in this study had greater than 50% viability. Six invasive species are traded in low volumes with viable propagules sold for five of these, highlighting a possibility of spreading through the traditional medicine trade. The study concluded that the total trade in alien plant species is trivial in comparison to the trade of indigenous plant species.
