- Description: Maritime heritage and its representation in South Africa, has been shaped by a settler colonial community heritage consciousness emphasising a heroic moral discourse legitimising local presence by settler communities. While much has been done to decolonise the representation of South African maritime heritage, at the local level small scale memorialisation continues to valorise maritime narratives that highlight the heroic aspects of historical settler colonial society, effectively concealing more fulsome of historical maritime events. Shipwrecks can function as potent tangible and intangible symbols of historical events, articulating a variety of perspectives on what constitutes social memory and history. This thesis examines the extension of public knowledge and representation of shipwreck maritime heritage on the Eastern Cape’s coastal belt, known in tourist branding vernacular as the ‘Sunshine Coast’ (East London to Port Elizabeth). The case study of ‘The Volo’, a Norwegian barge wrecked near present day Kenton-on-Sea and Bushman’s River Mouth (Boesmansriviermond) demonstrates how shipwreck narratives presented at the local public level can articulate a settler colonial community heritage consciousness that erases wider accounts of such stories. The reinterpretation and decentring of settler colonial maritime heritage stories allows for a more diverse and inclusive narrative that has the potential to promote social cohesion and social justice within restorative history work. , Thesis (MA) -- Faculty of Humanities, Anthropology, 2024

- Description: There is growing awareness of the value and central role of immediate and long-term mental health and psychosocial support (MHPSS) interventions, especially during times of crisis such as Covid-19. The World Health Organization has identified the education sector as a crucial intervention site for public mental health promotion. In collaboration with members of the Makhanda education community, the Rhodes University Community Engagement office identified psychosocial support for educators and educational practitioners as a key societal and educational challenge. Focusing specifically on the experiences of educators, this study sought to solicit their experiences of MHPSS workshops in a rural city of the Eastern Cape province of South Africa. Focus groups with educators and educational practitioners in non-government organisations, care centres and other educational settings who participated in the psychosocial support workshops were conducted. Data was analysed using community psychology’s social action framework. Four broad themes emerged from the data: the responsibilisation of educators during and post-Covid-19, educators’ resilience and support for each other, educators’ mental health promotion through psychosocial support workshops, and top-down intervention strategies that fall short in addressing educators’ and learners’ needs. This study demonstrates the value of university-community partnerships in education settings which are key sites for public mental health promotion. In this study, I advocate psychosocial support as a standard practice available for educational practitioners and show how professional training programmes in higher education can be responsive to societal challenges via collaborative approaches. , Thesis (MA) -- Faculty of Humanities, Psychology, 2024

- Description: This study examines the economic and social outcomes of participating in a global citrus value chain for selected commercial farmers and farm workers in Raymond Mhlaba Municipal District in the Eastern Cape, South Africa. A global chain refers to international production sharing through cross-border trade. Multilateral organizations (and some prominent global chain scholars) that support neoliberal economic globalization perceive global chains as ideal channels of economic and social upgrading for participants, particularly those from the global South. From the abovementioned perspective, global chains enhance efficiency through inter-firm relations that promote the distribution of technology and access to capital, thus leading to economic and social upgrading in developing countries. Economic upgrading, on the one hand, can briefly be described as the movement of supplier firms from lower to higher-value activities in global chains. Social upgrading, on the other hand, is the improvement of employment conditions and outcomes of workers employed by supplier firms at the production node of global chains. This study adopts the dual theoretical framework (Global Chain Framework and Labour Process Theory) proposed by Newsome, Taylor, Bair and Rainnie (2015) in their seminal book ‘Putting Labour in its Place: Labour Process Analysis and Global Value Chains’. This dual framework is ideal because it conceptualizes the spheres of trade exchange and production, which are the primary research sites of this study. Qualitative research methods were adopted and utilized to collect and analyse data in this study. These methods were ideal for this study, as they captured the subjective accounts of the selected commercial citrus farmers and farm workers in the Raymond Mhlaba Municipal District in the Eastern Cape, South Africa. The findings in this study showed that the outcomes of these selected commercial citrus farmers and farm workers in this region are variegated, meaning that, there is evidence of economic upgrading, social upgrading and social downgrading as well. Amongst farm workers in the region, only a small group of (mostly older male) farm workers enjoyed social upgrading, whilst the majority of seasonal (mostly female) farm workers experiences social downgrading. The findings in this study showed that the variegated economic and social outcomes of the selected commercial farmers and farm workers were primarily determined by their economic class and position within the citrus value chain of South Africa. These findings highlight the importance of positionality in determining the fate of participants in global chains. , Thesis (MA) -- Faculty of Humanities, Sociology, 2024

The CODESRIA debate on academic and intellectual freedom in Africa: the role and responsibility of African intellectuals

- Description: According to Fagunwa (2011), intellectuals serve as the glue that binds societies together and serve as the foundation upon which new civilizations are created and dismantled. The Council for the Development of Social Science Research in Africa (CODESRIA) of 1990 entrusted intellectuals with crucial transformative tasks (roles) and responsibilities in Africa. This study explores the transformational roles and responsibilities of African intellectuals in neo-liberal and neo-colonial Africa as well as how academic freedom must be understood by African academics in accordance with the present debate on academic freedom in South Africa, which was fueled by Nattrass (2020) paper. The primary premise of this study is that academic freedom in Africa today is viewed differently than it was during the CODESRIA meeting on academic freedom in 1990, and that this is because of African intellectuals not carrying out their roles and responsibilities in Africa. In CODESRIA 1990, academic freedom referred to an academic’s unrestricted, yet responsible, right to pursue their academic interests (CODESRIA 1990; Kampala Declaration 1990). African academics now understand academic freedom to be merely their own freedom, unrelated to their responsibility to use it ethically and professionally. Hence, for them, academic freedom entails the freedom to express oneself without restrictions or fear of criticism (Chachage, 2008; Nattrass, 2020b; Esso, and Long, 2020). Looking at this current misinterpretation of academic freedom, the 1990 CODESRIA meeting is a good reference point to the debate on academic freedom in Africa and role and responsibility of African intellectuals. This is because, it was where academic freedom and the role and responsibility of African intellectuals in Africa was professionally conceptualized. Thus, this study reviews the 1990 CODESRIA debate to understand the role and responsibility of African intellectuals. This study utilizes two theories, Social Constructivism Theory and the Social Responsibility Theory, to explain the position it has taken on the subject at hand. Thus, these theories provide an umbrella and a point of departure for understanding the context and dynamics of the ongoing conflict between academic freedom and social responsibility in South Africa's higher education institutions. , Thesis (MSocSci) -- Faculty of Humanities, Political and International Studies, 2023

- Description: As has been noted in the previous section little or no complex formation occurs with either formate or acetate except possibly above pH 9*0 or so. These anions do not stabilise the aluminium solutions to precipitation - they may* however, be of value in controlling pH, as solutions of these salts buffer strongly in the region pH 4 to 5. The other salts, lactate, tartrate and citrate all show tendencies to complex formation though the degree to which this occurs varies with the anion. The complexes formed by lactate at high pH must be very unstable because on the addition of acid the pH corresponds to the calculated blank. Below pH 9.0 however, the curves deviate quite considerably showing that more acid must be added to reach a certain pH value than is required by the blank. This means complex formation has occurred with loss of -COGH groups. In this system too, buffering is apparent. The same is true of tartrate but this salt is not as efficient a buffering agent. This is probably due to the fact that the excess tartrate is not available as a buffer as it is precipitated as the acid salt which is only sparingly soluble. Citrate on the other hand must form very stable complexes, the effect of which is apparent at even very high pH values. In other words, addition of strong acid liberates free -GOGH groups which are immediately incorporated in the complex. This evidently does not occur with lactate or tartrate until lower pH values are reached. The ratio of lactate and citrate to aluminium appears to have some influence on the degree of masking as greater complex formation is found to occur at the higher ratio levels. Tartrate on the other hand apparently has a fixed complex forming capacity between 1 and 4 mols/mol aluminium, since the same deviation from the blank was observed irrespective of which ratio of the masking agent to aluminium, was employed. However, at ratios of less than 1 mol tartrate/mol aluminium, deviations from the blank were reduced and less stabilisation occurs as evidenced by the formation of precipitates containing aluminium under these conditions. In view of these facts it may be suggested that 1 mol tartrate combines with 1 mol aluminium to form a complex containing equimolar proportions of aluminium and tartrate. The effect of boiling apart from one or two exceptions always has the same effect, i.e. a shift to the acid side of the curve. Free acid must have been liberated which is an indication that olation might have occurred. In the lactate and citrate series dilution appears to reduce the complex forming capacity of these ions but tartrate is unaffected. Thus it would appear that the tartrate complex is more stable than those formed by lactate. Citrate stabilises aluminium solutions with fewer equivalents than tartrate, but the complex does not contain a constant ratio of masking agent to aluminium further quantities of tartrate cannot enter the complex even in the presence of large excess of the anion probably due to the effect of steric hindrance. , Thesis (Dip) -- Leather Industries Research Institute, 1950
