- Description: A detailed empirical focus on the social impacts of progressive land policy shifts on women in Africa remains limited, particularly when it comes to urban property rights. This study examined contemporary dynamics of gender and access to urban property in the context of South Africa’s post-apartheid radical policy changes that attempt to address primarily the historical exclusion of blacks from urban property rights and housing. The thesis adopted a gendered approach to the concept of ‘access’ as an overriding concept to analyse the impacts of land tenure upgrading on women’s access to urban land and housing in Mdantsane, South Africa’s second-largest township. This study also adopts a liberal feminist perspective, particularly egalitarian liberal feminism (emanating from the works of John Stuart Mill) to explore how the post-apartheid progressive institutional and legal reforms have influenced the autonomy and power of women to access urban property rights. Through this perspective, the study also draws on several key theoretical concepts to put together a conceptual schema – a framework – that provides enhanced understanding of gendered dimensions of access to urban landed property (in this case housing). In many developing countries, there has been a shift from indigenous land tenure systems to private land ownership. These shifts were caused by several factors, including population pressure, rising land income, urbanisation, and land grabbing. International organisations such as the World Bank, the United States Agency for International Development and Department for International Development have expanded their land tenure reform programmes in developing countries from the 1970s until the late 1990s. These have suggested individualised land rights (land titling) as a precondition for investment, economic progress, poverty alleviation, and a framework for secure, transparent, and enforceable property rights. Gender equity became a growing concern among donor institutions that promote and fund titling and registration programmes. Land titling was viewed as a solution to bring an end to gender inequalities in land ownership. In South Africa, the Upgrading of Land Tenure Rights Act 112 of 1991 (ULTRA) was enacted for upgrading and converting ownership of certain rights granted in respect of land. The study used a case study of women in sections of Mdantsane. Qualitative methods, mainly in-depth interviews and life histories enabled the researcher to obtain detailed personal accounts of the historical and contemporary struggles of black women in accessing land and property in South Africa’s urban peripheries. The findings demonstrate that tenure upgrading produced differential outcomes among women in Mdantsane, and some diverse meanings that women attach to their land and houses in the context of tenure upgrading in post-apartheid South Africa. While tenure upgrading has guaranteed non-eviction for most house occupants (including women), it resulted in eviction for others. Male occupants, who secretly and fraudulently acquired the title deeds for family houses, displaced some of their women relatives. The study also established that these displacements were mostly done by those men who were regarded as heirs to property in many of the urban households. As such, they took most decisions about the formal registration of family homes, thus weakening the rights and power of women over urban property. Among the dominant meanings attached to land after tenure upgrading, women in Mdantsane generally viewed the ownership of urban property – no matter how small – as a form of empowerment, socially and economically. This study also found that after tenure upgrading, other women lost access to the accommodation they rented for more than a decade, even though they qualified to become the owners. In some instances, the politicians fraudulently sold the houses, and the occupants were thus displaced. Poor housing administration by the municipal officials was one of the reasons most occupants lost access to housing. In general, the results indicate that post-apartheid, urban land laws and policies afforded women better access to land and housing. Furthermore, in several instances, titling afforded women equal ownership rights as men compared to other tenure systems. Nonetheless, the history of exclusion still negatively affects women’s access to land and housing. Even in cases where they are not excluded, women still face social, political, and cultural constraints in acquiring urban land. Such a finding indicates that, gender-sensitive land laws and policies do not automatically lead to positive outcomes for women in South Africa’s urban peripheries. Therefore, the struggle for equal property rights does not begin and end with gender-progressive laws. Urban land policy should also grapple with past and contemporary obstacles in the implementation of legislation. , Thesis (PhD) -- Faculty of Social Sciences and Humanities, 2023

- Description: Family businesses are fundamental for any world economy where they contribute significantly to economic prosperity. However, family firms are faced with new obstacles that are directly affecting their business performance due to the current economic uncertainties and the rapidly changing environments. The implementation of dynamic capabilities is a fundamental strategic tool family firms can exercise to improve their competitive advantage. Although family business research has proliferated over the last 10 years, there are few studies in South Africa investigating the extent to which dynamic capabilities influence family business performance. This study, therefore, had a primary objective to investigate the determinants of family business performance and the role that dynamic capabilities play as mediators and moderators. Studying such a research theme has not received sufficient attention within the family business field, which emphasises the need for such a topic to be investigated. The independent variables for the study entailed dynamic capabilities and decision-making constructs while the dependent variable comprised family business performance. Consequently, the mediating variables included strategic foresight, strategic flexibility, and strategic creativity while the moderating variables included strategic creativity and strategic flexibility. This investigation followed a quantitative methodological logic by employing the questionnaire as the research instrument. In total, 347 family business managers and owners from the eight districts of the Eastern Cape participated in the study. The family businesses were accessed through a convenience sampling technique to identify if their business suited the inclusion criteria of the study. Data analysis was executed through SPSS where the moderation-mediation analysis followed the Hayes process macro through multiple regression analysis. The research findings revealed that there is both a significant positive and mediation relationship between the dynamic capabilities constructs entailing environmental scanning, scenario planning, knowledge creation, culture, and formal organisation with the decision-making constructs of strategic foresight, flexibility, and creativity with family business performance. Interestingly, a moderation relationship does not exist between these constructs and the strategic foresight of the family firm. However, a moderation relationship does exist between the dynamic capabilities constructs of knowledge creation and culture and strategic foresight when moderated by strategic creativity. Thus, family business performance is positively influenced by the said dynamic capabilities and decision-making constructs. The results ultimately provided implications for family businesses with practical advice on the successful implementation and monitoring of dynamic capabilities and decisionmaking in the family business. Lastly, this study makes recommendations for family and non-family business owners, government, and academics. These recommendations entail family businesses implementing a lucrative dynamic capability model to improve family business performance in the context of South Africa. , Thesis (PhD) -- Faculty of Management and Commerce, 2023
