- Description: Young female action heroes have recently stepped into the limelight as commercial celebrations of Girl Power in Hollywood action-adventure films. Feminist films studies however have shown that these independent, tough female heroes claimed as feminist, are still constrained in various ways through stereotypical gender roles within the action-adventure genre. This thesis examines these claims through the ideological analysis of the young female action hero Katniss in The Hunger Games film franchise. Building on existing research on female action heroes, the research asks: ‘to what degree can the claim of Katniss as boundary-breaking, feminist hero be validated’? This question is addressed through a textual analysis of the four films of The Hunger Games film franchise, employing conventions of action-adventure genre, narrative analysis, mise-en-scène and cinematography to unmask the characterisation of the female hero. The discussion of the findings, utilising the themes of Love, Violence and Power, reveal both progressive and regressive elements present in the characterisation of Katniss. The findings indicate that while female action heroes can be celebrated for displaying progressive moments of liberated action, they remain constrained within dominant heteronormative gender roles in commercial Hollywood films, undergoing various acts of transformation and recuperation as a means of containing the threat of their transgressive behaviour.

- Description: This thesis offers a comparative reading of Ralph Ellison’s Invisible Man, Percival Everett’s Erasure, Zoë Wicomb’s Playing in the Light and NoViolet Bulawayo’s We Need New Names in order to explore the diversity of subjectivities included within the terms ‘African’ and ‘black’ and to argue for the necessity of renewed definitions of Africa(nness) and blackness which allow for diverse and fluid representations. The diverse historical and political contexts in which these novels are published, as well as the critical and theoretical discussions which surround them demonstrate an evolution in literary portrayals of identity politics. As the categories of race and nation become more fluid, so too do narrative forms. In particular, this thesis is interested in the textual strategies authors use to navigate the various ways in which depictions of blackness continue to be restricted by racism, stereotypes, and the dynamics of a global literary market. As portrayals and discussions of identity politics proliferate in popular culture, they become increasingly commodified, and therefore increasingly restricted by the market.

Between drones and al-Shabaab: United States extra-judicial killings in Somalia, sovereignty and the future of liberal intervention

- Description: This study examines the nature of the United States intervention in Somalia, specifically the use of drone strikes that first targeted the militant Sunni Islamist transnational group, al-Qaeda, which claimed responsibility for the 11 September 2001 attacks on the United States, and now target the Somali organisation, Harakat al-Shabaab al-Mujahidin, commonly known as al-Shabaab. The use of drone strikes in the US led war on terror has raised concerns about sovereignty as the extra-judicial killings are conducted without the consent of the concerned states. Furthermore, drone strikes also raise questions about the processes of liberal intervention as the US conducts them without the approval of the United Nations Security Council. It is argued in this study that what is understood to be the “golden era” of liberal interventionism is a legacy of the post-Cold War unipolar dominance of the United States in global governance and security. It is argued that US unipolarity was accompanied by a shifting perception regarding the security position of weak states, whose weakness becomes understood as a source of global insecurity. This perception that so called “weak” and “fragile” states are sources of threats is a departure in International Relations theory, because the discipline is historically preoccupied with studying the actions of powerful states and their consequence for the global order. It is argued that the discourse on the war on terror, and its focus on “failed states” as breeding grounds for alleged terrorists, represents the height of the repositioning of less powerful states from a peripheral status in IR analysis and practice, to their current position that are now being represented as core sources of threat to international peace and security. Through life history interviews with Somali nationals in Grahamstown, Port Elizabeth and Uitenhage, South Africa, the study examines the consequences of US actions from the eyes of Somali people. The findings of this study show that despite all the controversy surrounding the legitimacy of the war on terror, the manner in which it is conducted, as well as the tactics that it employs, the majority of Somali participants showed an overwhelming support for the US intervention. Participants expressed support for the US extra-judicial killings because they are understood to undermine al-Shabaab strength which is a major source of insecurity. The study also shows that the lack of necessary collaboration between the US intelligence and the Somali ground forces has resulted in high numbers of civilian deaths, which participants fear can be used by al-Shabaab to recruit and radicalise more Somalis. The study also shows that most Somalis resent the presence of the African Union Mission in Somalia because Kenya and Ethiopia are seen as 10 pursuing national interests that are not invested in Somali peace and stability. The study concludes that US extra-judicial killings have failed to constrain the actions of al-Shabaab. Somalis expressed that the leadership of current president, Mohamed Abdullahi Mohamed Farmaajo, holds the unique possibilities of creating national unity that rises above clan divisions and the radical Jihadist ideology of al-Shabaab.

- Description: Various characterization techniques have been used to characterize the synthesized asymmetrical zinc phthalocyanines (ZnPc) derivatives. Techniques include Ultraviolet-visible (UV-vis) spectrophotometry, matrix assisted laser desorption time of flight mass spectrometry (MALD-TOF MS), proton nuclear magnetic resonance (1H-NMR), elemental analysis and Fourier-transform infra-red spectroscopy (FT-IR). The complexes are covalently linked to core/shell and core/shell/shell semiconductor quantum dots (SQDs) via amide bond formation. Photophysical properties of complexes improved in the presence of semiconductor quantum dots (SQDs). SQDs contain cadmium/telluride (CdTe) as core, coated in the first shell with zinc selenide (ZnSe) or zinc sulfide (ZnS) and with zinc oxide (ZnO) in second shell. The photophysical properties of the phthalocyanine (Pc) complexes and their conjugates with SQDs are investigated in solution. Triplet quantum yields of complexes improved in the presence of semiconductor quantum dots. The optical limiting behaviour of the Pc complexes and conjugates are assessed using the open aperture Z–scan technique at laser excitation wavelength of 532 nm with 10 ns pulse. Pcs complexes showed good nonlinear optical response with higher nonlinear absorption coefficient. The conjugates afforded higher nonlinear absorption coefficient than Pc complexes alone.

- Description: South Africa, just like most African countries, is a country rich in social, political and economic history due to colonisation, specifically the apartheid system. The current socio-political and economic climate of the country is said to influence the process of identity development and formation during adolescence. Therefore, the main aim of the study was to explore the various identities that black adolescents are exploring given the context of the country. Additionally, the aim of this research was to explore the methods in which adolescents utilise to develop their identity and the challenges encountered during this process. The study made use of three data collection methods; a Short Reflective exercise, a Nominal Group Technique and Focus Groups. Data was analysed using thematic analysis to generate main themes and sub themes. The main themes discussed in this study revealed that adolescents experiences multiple aspects of their identity, which exist in a complex interwoven system influenced by both external and internal factors. The main challenge was the difficulty in integrating the dominant westernised/individualistic ideology with the collectivistic ideology that adolescents are raised according to. Overall, the study indicated that the majority of the participants had a positive self-concept and a positive outlook with regards to their future. Recommendations emphasise the need for further research that would be based on the South African context to further explore black identity and to gain contextual information that can be used to combat some of the social issues that the South African youth is challenged with.

- Description: This thesis seeks to explore the social identity of black students in a historically white university. Since 1994, South African government has been promulgating pieces of legislation aimed at ensuring racial integration, and indirectly enforcing acculturation in historically white universities. Studies have proven that institutional cultures in historically white universities alienate and exclude black students’ identities. These students’ sense of social identity, which includes amongst others; culture, heritage, language and traditions, and consequently self-esteem and self-concept is altered in these institutions. Research has been scant regarding the shape and form that black students’ identity assume when they get to these spaces. Face to face interviews were used to collect data and thematic analysis was used for data analysis. The Social Identity and the Acculturation models were used to explore the experiences of black students in negotiating their social identities in a historically white university. Evoking Steve Biko’s analysis of ‘artificial integration’, it was illustrated how the ‘integration’ narrative sought to discard the identity of black students and psychologically enforce a simulation of black students into white established identities. The main themes discussed indicated that black students in this study had social identity and identity challenges in a historically white university. This study has implications for policy development as I hope to theoretically sensitize historically white universities to (apart from mere opening of spaces of learning) understand the social identity challenges of black students.

- Description: The NW Province of Zambia is fast becoming a major significant mining district challenging to usurp the economic importance of the traditional Copperbelt Province that has been mined for nearly a century. With latest developments at Kansanshi, Lumwana and Kalumbila mines exploration efforts in the search for Copperbelt style mineralisation have doubled up in the province in recent months. Traditional methods of stream sediment and soil sampling, geophysics, aerial photo and Landsat imagery interpretations have been employed in exploration targeting campaigns. This thesis asks the question: Can we use the Copperbelt geochemical footprint as a proxy to finding new copper deposits in NW Province? The challenge faced in such studies is that few geochemical datasets for old mines exist and the little that does is proprietary information. In some mines this dataset is entirely nonexistent - at least not in the public domain. Attempting to run orientation geochemical trials on such mines is not feasible at present due to maturity of mining and the levels of contamination of the natural environment that have occurred over several decades of mining. However, in tackling this question few Copperbelt geochemical datasets from Baluba, Nkana, Mimbula, Nchanga, Bwana Mkubwa, Mufulira West and Lufubu North were used. The findings presented in this report are that for Copperbelt style mineralisation Cu/Co, Cu/Ni, Cu/Ag ratios in soil geochemistry data should be in the ranges of 0.25 to 0.48 provided geochemical studies occurred in residual soils. These ratios hold true for sediment hosted copper-cobalt mineralisation hosted at various stratigraphic levels within the Roan Group or in upper levels elsewhere on the Central African Copperbelt. Geochemical dataset for the study areas presented in this report show that the soil geochemistry footprint in the province is not dissimilar to the soil geochemistry footprint of the traditional Copperbelt Province. This means there is great potential for finding Copperbelt style mineralisation in the province and other styles of mineralisation in which copper is associated with cobalt, lead, zinc, nickel, vanadium and molybdenum. The areas of study also possess requisite geological factors that are conducive to hosting Copperbelt style deposits. These factors include: favourable structural traps with similar trends to existing mines in the province, geophysical characteristics comparable to other deposits in the province, right geological package known to host multi-type deposits in the Katangan stratigraphic sequence, and similar geochemical footprints observed on other deposits within the Lufilian fold belt. For this reason, geochemical dataset must not be looked at in isolation but should be treated in considerations with other factors and geological environment.

- Description: This thesis presents a study of the relationships between Somali spaza operators and the villagers living in the villages around Cofimvaba. The Somali spaza operators are operating spazas in the villages around Cofimvaba in the Intsika Yethu District Municipality (IYDM) located in the Chris Hani District Municipality (CHDM). Spaza shops are general dealers selling daily consumption items, which usually operate in the informal sector, primarily in poorer black neighbourhoods, both urban and rural. Resentment of the very visible, post-apartheid, expansion of immigrant entrepreneurship - in the informal sector, notably in spazas- has been central to South African anti-immigrant sentiment, popularly dubbed “xenophobia,” which casts foreigners, mainly black or Asian, as stealing South African resources. Foreign spaza operators, many of them Somalis, have been subject to ongoing violence and looting for well over a decade, notably in the Eastern Cape and Western Cape provinces. Yet in the deeply impoverished villages around Cofimvaba, in the former Transkei black homeland in the Eastern Cape, where Somalis play a central and growing role in spazas, such attacks are unknown. The aim of this thesis is to understand why. Careful qualitative research in several villages has indicated key reasons. These include the relative absence of South African, locally- owned spazas, and so, the lack of a local group driving xenophobic resentment; the convenience offered by Somali-owned spazas in these isolated villages, the affordability of the products offered, and the availability of systems of credit for villagers; the investment of the Somali entrepreneurs into the villages through acts like charity; and their social interaction with villagers. The Somalis have redefined the local spaza sector, to the benefit of the villagers, and there is a degree of “xenophilia” as a result. The research also found that the growing number of Somali spaza operators in the villages was a direct result of the xenophobia experienced by this group in the urban townships. The villages around Cofimvaba benefit the Somali operator, not in a financial sense as these are not where the most profits have been made, but as sites where the traders feel safest. But although the villages are a sort of refuge, they are isolated and isolating. The Somalis resident in these areas struggle to maintain the strong ethnic group consciousness based on a strong vision of the Somali homeland, and a sense of being sojourners, hoping to relocate elsewhere.

- Description: This thesis presents a study of the relationships between Somali spaza operators and the villagers living in the villages around Cofimvaba. The Somali spaza operators are operating spazas in the villages around Cofimvaba in the Intsika Yethu District Municipality (IYDM) located in the Chris Hani District Municipality (CHDM). Spaza shops are general dealers selling daily consumption items, which usually operate in the informal sector, primarily in poorer black neighbourhoods, both urban and rural. Resentment of the very visible, post-apartheid, expansion of immigrant entrepreneurship - in the informal sector, notably in spazas- has been central to South African anti-immigrant sentiment, popularly dubbed “xenophobia,” which casts foreigners, mainly black or Asian, as stealing South African resources. Foreign spaza operators, many of them Somalis, have been subject to ongoing violence and looting for well over a decade, notably in the Eastern Cape and Western Cape provinces.

- Description: The overall aim of this thesis is to explore the process of working with the Edwards claywork method with a psychotherapy client who had significant relational difficulties and feared being exposed as defective. Within this there are particular aims: Firstly, to investigate whether the distancing that art therapy can create, can help the client with relational difficulties to tolerate unexpressed disavowed feelings, in particular her sense of shame about being exposed as defective; and secondly, to examine whether material evoked through the claywork process can assist in furthering the psychological formulation of this kind of client. The research was a phenomenological-hermeneutic case study of a psychotherapy client, called Kim. Kim’s experience of therapy, including two claywork sessions, was documented. This comprises a thematic narrative of her therapy process prior to the claywork process, as well as a thematic narrative focusing on the two claywork sessions. Her clay sculpture was photographed and alphabetically labeled according to the chronological order in which she made the eight pieces comprising her sculpture. A hermeneutic reading of the narratives was conducted using theoretical perspectives including object relations, Adlerian psychology and art therapy. It was concluded that, firstly, the distancing that art therapy can create does help the client, who is afraid of being exposed as defective, to tolerate previously disavowed and unexpressed feelings; and secondly, art therapy such as the Edwards claywork method, does deepen psychological formulation of the client’s affective and relational difficulties. However, although the image may graphically symbolize unconscious aspects of a client’s psyche, the present study illustrates that a client may not always be able to enter into a relationship with the image or dialogue between conscious and unconscious states. In this respect, the present study focuses on aspects of art therapy of which there is limited literature.

- Description: Muscle strength has been identified as an important contributor to athletic performance. Little attention however, has been paid to the specific relationship between peak isokinetic muscle strength and sprint starting performance. The aim of this study was to determine the influence of an adapted front knee angle, as determined by isokinetic assessment (the angle of peak torque production), on starting performance. Sixteen track sprinters, of elite-national or competitive-regional standard, were asked to perform eight sprints over 50m using four separate starting techniques. Technique 1 featured the athlete’s usual starting preferences while Techniques 2, 3 and 4 featured a standardised set of starting preferences with experimental modifications of the front knee angle in the “set” position. Isokinetic muscle strength was measured at slow (60°/s) and fast (240°/s) test speeds in order to determine the angle of peak torque production for concentric knee extension of each subject’s lead leg. Using one-way analysis of variance (ANOVA) and Post Hoc analysis (LSD), no significant differences (p>0.05) were observed between the experimental techniques for: block time, force-time measures during block time, sprint times, sprint velocity and acceleratio n measures at intervals up to 50m. Significant differences (p<0.05) were however observed between reaction times for the experimental techniques. Slower reaction times are most likely due to increased upper body pretension, resulting from the increased hip elevation seen for these techniques. The results indicate that increased hip elevation may have delayed the initiation of the relevant motor response required to affect an optimal sprint start. Technique 1 resulted in the shortest reaction times, shortest block times, fastest sprint times and greatest sprint velocities for all four techniques. This result was possibly due to the athlete’s experience with, and repeated use of, this technique. The experimental techniques therefore provided no added advantage over the subject’s preferred starting technique and did not significantly optimise sprint starting performance. The results show that modification of the front knee angle had no significant influence on sprint starting performance and sprint running ve locity or acceleration patterns up to 50m. Using Pearson’s Correlation Coefficient to determine the strongest correlations between isokinetic knee strength and sprint starting performance, analysis revealed that the strongest relationships were found between sprint starting performance expressed as acceleration and isokinetic knee strength expressed as relative peak torque and absolute peak torque. For Technique 1 the strongest correlation was found between acceleration (30m - 40m) and relative peak torque as measured at a test speed of 240°/s (r = 0.62). For the remaining experimental techniques, the strongest correlation was found between acceleration (10m - 20m) and relative peak torque as measured at a test speed of 60°/s (r = 0.53) for Technique 2, between acceleration (40m - 50m) and peak torque measured at a test speed of 60°/s (r = 0.72) for Technique 3, and between acceleration (0m - 5m) and peak torque as measured at a test speed of 240°/s (r = 0.71) for Technique 4. These results suggest that isokinetic muscle strength does not correlate strongly with sprint starting performance and that additional factors, such as neuromuscular organisation and muscle fibre typing, possibly make a greater contribution to optimal sprint starting performance.

Geological factors that influence the evaluation and exploitation of Canadian copper-zinc massive sulphide-, and Japanese polymetallic (kuroko) deposits

- Description: Volcanogenic massive sulphide deposits are important sources of base metals throughout the world. The Canadian Cu-Zn-(Au, Ag) deposits of Archaean age occur in greenstone terrains within the Canadian Shield. These deposits are closely associated with volcanic vents developed along zones of rifting within mobile belts. The vents are manifested by coarse felsic pyroclastics and/or rhyolitic domes. The Japanese Pb-Zn-Cu-Ba(Ag) deposits, generally known as Kuroko deposits, are of Miocene age, and although also associated with volcanic vents, are developed above zones of subduction. Mineralization in volcanogenic deposits is a result of submarine exhalation of metalliferous hydrothermal solutions derived from fractionation of predominantly calc-alkaline magmas. The deposits are characterized by certain geological features that result from the interaction of specific physical and chemical conditions during deposition. Primary features include massive and stringer sulphide bodies, alteration zones, mineralogical and metal zoning, and certain depositional textures and structures. These features are commonly modified by subsequent metamorphism and deformation which impart secondary ore textures and affect metal distribution and shape. The disparity in age between Canadian and Japanese deposits allows the entire spectrum of geological features to be studied; from the completely unaltered to the high deformed and recrystallized. The characteristic geological features are the prime factors which control the metal distribution and concentration, and the size and shape of the deposits, thereby influencing the viability of the respective ore bodies. A knowledge of these factors and the physico-chemical parameters which control them are thus fundamental in the "understanding" of these deposits. They ultimately control the geological interpretations and predictions made during ore body delineation, ore reserve estimation, mining and ore beneficiation.
