- Description: This study probes the ethics-oriented reflexive deliberations of three novice environmental education practitioners in South Africa. Two of the cases examined work in a local government context, and the third in an environmental non-governmental organisation context. All three practitioners are studying a one-year professional development course in environmental education. The research asks how their ethical deliberations ‘come to be what they are’, at the interface of their workplace and course-based learning processes. Working within a relational, social realist ontology, the study takes a sociocultural-historical approach to learning, development and social change. Cultural-historical activity theory (CHAT) provides theoretical tools and a descriptive language to approach the rich, qualitative data derived from workplace and course observations, extensive interviews, and document review. Critical discourse analysis was used as a secondary analytical tool to probe ethical and environmental discourses that were found to be influential in the course and workplace activity systems. Data from the three case studies was analysed in stages. In the first stage, CHAT provided a theoretical perspective and language of description to analyse the interacting activity systems in which each learner-practitioner’s ethics-oriented reflexive deliberations occurred. This provided a platform for the second stage of analysis which was framed by Margaret Archer’s (1995) social realist theory of morphogenesis/ morphostasis, followed by a summative retroductive analysis, to give an account of the interplay of historically-emergent social and cultural structures and individual reflexivity in relation to the ethical dimensions of environmental education practice. The study traces how ethics-oriented reflexive deliberations occur at the untidy, unpredictable intersection of workplace, course and personal contexts, and are strongest when they are situated in authentic contexts that resonate with learner-practitioners’ ‘ultimate concerns’ (after Archer, 2003; 2007). In this study, the learner-practitioners’ ‘ultimate concerns’ included family, personal well-being, social justice, cultural identity and religious commitments. The scope and depth of learner-practitioners’ social-ecological knowledge was also identified as a key factor influencing ethics-oriented reflexive deliberations, although the mediation of such knowledge can be hindered by language and conceptual ii barriers, amongst others. The study also noted how ethical positions circulating in the workplace, course and personal contexts were diverse, uneven and dynamic. Some ethical positions were found to be more explicitly differentiated than others, either resonating with or being overlooked by the learner-practitioners as they deliberated the ethical dimensions of their environmental education practice. In situations where there was limited depth, conceptual clarity and/ or confidence to engage directly with ethical concerns, there was a tendency towards (inadvertent) ethical relativism. Insights derived from the study suggest that these factors have limiting effects on the ethics-oriented reflexive deliberations of novice environmental educators. These insights point to the need for ethical deliberations to be re-personalised in context and underpinned by depth knowledge. A relational and pragmatic approach to environmental ethics (that recognises the validity of judgemental rationality – which can be fallible – and which seeks out practical adequacy) is put forward as appropriate and potentially generative in environmental education and training processes. This would need to be supported by careful attention to the influence of environmental discourses and practices in shaping ethical deliberations, and may also be helpful in developing a much-needed accessible, everyday language of ethical engagement. This study’s contribution to new knowledge in the field of environmental education is through its account of ethics-oriented reflexive deliberations emerging (in the Archerian morphogenetic sense) in complex, indeterminate ways at the interface of sociocultural and social-ecological contexts. The ethics-oriented reflexive deliberations of novice environmental educators occur in relation to their ‘ultimate concerns’ and are advanced or hindered by the historically-emergent practices, discourses and material realities of their workplace, personal and educational contexts. These insights require that the complex interplay of intersecting contexts and concerns that shape ethics-oriented reflexive deliberations be acknowledged and carefully mediated in both workplace-based and coursebased professional development processes.

- Description: Poverty in South Africa is vast. This is an open secret as it manifests itself in so many ways. It is widely known that South Africans are faced with one of poverty indicators, such as unemployment; hence our government is committed to fight poverty in various ways like, poverty alleviation, poverty eradication and poverty reduction programmes. This study looked at poverty of targeted people after Zamokuhle Ngcweleni was implemented. The researcher looked at the project’s contribution on poverty under sustainable livelihood approach with guidance of OECD(1991) criteria of judging the project these being; relevance, effectiveness and sustainability South Africa is committed in this regard with policies and strategies directed to fight poverty, Altman, Hart and Jacobs (2009). In the Constitution of South Africa (Act 1996) section 27 (1) (b)-(c) of this country, poverty is set to be fought, that people must have access to food sustainably through food security strategy. Government, through its departments commits to deliver to mostly affected people, services that deal with poverty reduction. The Department of Social Development is one of the vehicles to get these services to poverty stricken people blamed to history, politics and social ills. It is upon this background the study is done. The community of Ngcweleni with the assistance of the Department of Social Development and Special Programme has assumed this project, the Zamokuhle Ngcweleni with two activities, household gardens and egg production. 30 beneficiaries would sell for income and feed from the produce .This project started in 2010/11 financial year by the sub section, sustainable livelihood in the DOSD, based from the socio economic conditions of Ngcweleni where poverty is one the characteristic. The Zamokuhle Ngcweleni project was randomly chosen by the researcher for this study. The research was based on the aims and objective of the study. The study took place in a natural setting and was descriptive. Interviews, focus groups, documents and household survey were used by the researcher as data collection tools. The study was qualitative. Data was analysed using themes and interpreted thereafter. Participants were the beneficiaries of the Zamokuhle Ngcweleni project and officials of the department. Tables and graphs were used for biographical information to show age, gender, educational and marital status of the beneficiaries; for officials it showed qualification, designation and gender. The researcher gathered that the project has contributed positively to the poverty of the beneficiaries because of its relevance and effectiveness. It made beneficiaries food secure and the impact showed poverty is reduced. The project showed unsustainability and the researcher recommends the needs to investigate this further.

- Description: There is a gap in healthcare service delivery within low resource settings of South Africa. These areas are under-serviced because of poor health infrastructure and few available medical experts. This contributes immensely to poor health care delivery especially to chronically ill diabetic patients and increases mortality rates. However, innovative remote patient monitoring (RPM) systems have been developed to curb the above challenge in recent years. Unfortunately, most of these systems are standalone and are incompatible with one another. Most of them relay on Internet for connectivity which is imminent in low resource settings. This makes continuity of care of chronic ill patients a great challenge. Additional, the efficacy and feasibility of RPM using mobile phones in low resource settings of South Africa are still unknown. It was also noted that none of these systems have been developed for a clinical trial. The goal of this study was to provide a standard framework that allows optimal design of mobile RPM systems which are interoperable. The objectives were to investigate the RPM system efficacy and reliability in low resource settings and determine its effects on clinical management, self-care and health outcomes. The framework was validated with a clinical trial to remotely monitor diabetic adults in Limpopo province of South Africa. A prototype system was developed based on sound user centric design process and enterprise architectural principles to remotely monitor diabetic elderly patients using cellular technologies and existing hospital infrastructure. It was evaluated using a controlled, randomized clinical trial for 6 months. There were 120 patients who took part in the study and were categorized into two groups, the intervention Group X and the control Group Y. Each group comprised of 60 participants. Evidence from this study justified the feasibility and possibility of long term implementation of RPM system to cater for chronic ill patients in low resource settings worldwide. Results showed that the self-care and normal blood glucose levels improved for both groups whereas quality of life improved only for Group X. It was shown that extensive self-care knowledge with the help of RPM system improved self-care and helped normalize their glucose levels. The hospital admissions and mortality between the two groups did not differ much. However, the intervention group had more hospital visits than the control group because the participants were requested to visit the hospitals in case of emergency. The users perceived the RPM system as feasible and effective way of clinical management and self-care. Due to wide acceptance, some patients were even willing to continue using the system after the trial. Home measurements proved to be reliable and helped improve self-care. In future, a standardized and unified framework based on rule set would provide comprehensive remote healthcare allowing continuous patient monitoring at a reduced overall cost thereby decreasing mortality rates.

- Description: The combination of chemotherapy and photodynamic therapy was investigated by synthesis and characterization of octacarboxy phthalocyanine covalent conjugates with platinum complexes. This work presents the synthesis, characterization and photophysicochemical properties of aluminium (diaquaplatinum) octacarboxyphthalocyanine and aluminium (diammine) octacarboxyphthalocyanine. The conjugates were prepared by conjugating aluminium octacarboxy phthalocyanine with potassium tetrachloro platinate to yield aluminium tetrakis and trikis (diaquaplatinum) octacarboxy phthalocyanine. The aluminium octacarboxy phthalocyanine was also conjugated with cis-diamminedichloroplatinum to yield aluminium bis and tris (diaquaplatinum) octacarboxy phthalocyanine. From the characterization of the conjugates it was discovered that the aluminium (diaquaplatinum) octacarboxy phthalocyanine had formed platinum nanoparticles with the Pc acting as a capping agent. The triplet lifetimes decreased with the increasing number of platinum complexesconjugated to the Pc. The heavy atom effect improved the overall photophysicochemical properties.

- Description: In recent years, immense effort has been channelled towards the Information and Technological development of rural areas. To support this development, telecommunication networks have been deployed. The availability of these telecommunication networks is expected to improve the way people share ideas and communicate locally and globally, reducing limiting factors like distance through the use of the Internet. The major problem for these networks is that very few of them have managed to stay in operation over long periods of time. One of the major causes of this failure is the lack of proper monitoring and management as, in some cases, administrators are located far away from the network site. Other factors that contribute to the frequent failure of these networks are lack of proper infrastructure, lack of a constant power supply and other environmental issues. A telecommunication network was deployed for the people of Dwesa by the Siyakhula Living Lab project. During this research project, frequent visits were made to the site and network users were informally interviewed in order to gain insight into the network challenges. Based on the challenges, different network monitoring systems and other solutions were deployed on the network. This thesis analyses the problems encountered and presents possible and affordable solutions that were implemented on the network. This was done to improve the network‟s reliability, availability and manageability whilst exploring possible and practical ways in which the connectivity of the deployed telecommunication network can be maintained. As part of these solutions, a GPRS redundant link, Nagios and Cacti monitoring systems as well as Simple backup systems were deployed. v Acronyms AC Access Concentrators AMANDA Automatic Marylyn Network Disk Archiver CDMA Code Divison Multiple Access CGI Common Gateway Interface.

Saul Msane: friend or foe of the people? The life of the late nineteenth to early twentieth centuries South African politician and journalist

- Description: Saul Msane was a prominent founding member of the ANC and an active journalist and editor of the ANC newspaper Abantu-Batho. His career generated controversy. Towards the end of his life, he had a feud with his colleagues in the African National Congress (henceforth Congress) that led to him being labelled isitha sabantu, “the enemy of the people” for his refusal to support the Shilling strike of 1918, an accusation which was retracted a year after his death in 1919. The label of isitha sabantu levelled against Msane, had the effect of ending his political prominence in the Transvaal, forcing him to relocate to kwaNongoma where he died shortly thereafter. Msane’s years in the Congress amounted to about seven years, between 1912, the founding of the Congress, and the demise of his career in 1919. Msane’s seven years in Congress were characterised by controversies, clashes, and conflicts owing to his perceived elitism. In Congress historiography Msane is an obscure and elusive figure, he lives here and there in a footnote, as a supporting statement or a mentioned in mere passing. His marginalisation reveals some of the gaps within the history of Congress and invites us to write about those who did not emerge from the history of Congress necessarily as heroes. This thesis sets out to write a biography of Msane and document his political career beyond that one moment in which he came to be “isitha sabantu”. While Msane’s Congress career was comparably short and filled with tensions, an archive of his life exists. This study is an exploration of that archive to reconstruct the biography of a once prominent leader who dies in political exile from the Congress movement. This thesis sets out to do two key things in relation to reconstructing Msane’s life: Firstly, it reconstructs the longer biography of Msane’s political life by drawing on the existing archives, and thus filling in the South African historical record in that regard. Secondly, at the broader conceptual and historiographical level, it argues that the controversies surrounding Msane’s persona and character illustrate that conceptions of elitism and the nature of being ‘elite’ were key to the politics of Congress at the time. , U-Saul Msane wayengomunye wabasunguli beqembu lika-African National Congress (uKhongolose) futhi eyIntatheli nomhleli wephephandaba i-Abantu-Batho. Umsebenzi ayewenza waba nezingqinamba eziningi ngokwezepolitiki. Ngasekugcineni kwempilo yakhe waba nokungazwani nabaholi ayesebenza nabo kuKhongolose okwadala ukuba abizwe ngesitha sabantu ngenxa yokuba engavumelananga nesiteleka sango-1918 lapho abasebenzi babelwela ukukhushulelwa amaholo. Leligama lokubizwa ngesitha sabantu lahoxiswa ngo 1919 sekudlule unyaka engasekho emhlabeni. Lokubizwa ngesitha sabantu kwalilimaza igama lakhe kwezepolitiki e-Transvaal waze wathutha wayohlala kwaNongoma nokuyilapho ashonela khona. Iminyaka uMsane ayisebenzele uKhongolose yaba isikhombisa, kusukela ekusungulweni kwayo ngo 1912 kuze kufike ekulimaleni komsebenzi wakhe wezepolitiki ngo 1919. Kuleminyaka eyisikhombisa umsebenzi wakhe kuKhongolose wawubhekene nokugxekwa okukhulu nokubukeka njengomuntu onokuzenza ngcono kunabanye abantu. Emlandweni kaKhongolose uMsane akavezwa ngendlela emfanele, kukhulunywa ngaye kudlulwa nje. Lokunganakwa kukaMsane emlandweni kaKhongolose kusiphoqa ukuba sibhale ngabaholi abangaqakanjiswa. Lolucwaningo luveza umlando kaMsane ngokujulile ngaphezu kwangalesikhathi abizwa khona ngesitha sabantu.

- Description: Saul Msane was a prominent founding member of the ANC and an active journalist and editor of the ANC newspaper Abantu-Batho. His career generated controversy. Towards the end of his life, he had a feud with his colleagues in the African National Congress (henceforth Congress) that led to him being labelled isitha sabantu, “the enemy of the people” for his refusal to support the Shilling strike of 1918, an accusation which was retracted a year after his death in 1919. The label of isitha sabantu levelled against Msane, had the effect of ending his political prominence in the Transvaal, forcing him to relocate to kwaNongoma where he died shortly thereafter. Msane’s years in the Congress amounted to about seven years, between 1912, the founding of the Congress, and the demise of his career in 1919. Msane’s seven years in Congress were characterised by controversies, clashes, and conflicts owing to his perceived elitism. In Congress historiography Msane is an obscure and elusive figure, he lives here and there in a footnote, as a supporting statement or a mentioned in mere passing. His marginalisation reveals some of the gaps within the history of Congress and invites us to write about those who did not emerge from the history of Congress necessarily as heroes. This thesis sets out to write a biography of Msane and document his political career beyond that one moment in which he came to be “isitha sabantu”. While Msane’s Congress career was comparably short and filled with tensions, an archive of his life exists. This study is an exploration of that archive to reconstruct the biography of a once prominent leader who dies in political exile from the Congress movement. This thesis sets out to do two key things in relation to reconstructing Msane’s life: Firstly, it reconstructs the longer biography of Msane’s political life by drawing on the existing archives, and thus filling in the South African historical record in that regard. Secondly, at the broader conceptual and historiographical level, it argues that the controversies surrounding Msane’s persona and character illustrate that conceptions of elitism and the nature of being ‘elite’ were key to the politics of Congress at the time. , U-Saul Msane wayengomunye wabasunguli beqembu lika-African National Congress (uKhongolose) futhi eyIntatheli nomhleli wephephandaba i-Abantu-Batho. Umsebenzi ayewenza waba nezingqinamba eziningi ngokwezepolitiki. Ngasekugcineni kwempilo yakhe waba nokungazwani nabaholi ayesebenza nabo kuKhongolose okwadala ukuba abizwe ngesitha sabantu ngenxa yokuba engavumelananga nesiteleka sango-1918 lapho abasebenzi babelwela ukukhushulelwa amaholo. Leligama lokubizwa ngesitha sabantu lahoxiswa ngo 1919 sekudlule unyaka engasekho emhlabeni. Lokubizwa ngesitha sabantu kwalilimaza igama lakhe kwezepolitiki e-Transvaal waze wathutha wayohlala kwaNongoma nokuyilapho ashonela khona. Iminyaka uMsane ayisebenzele uKhongolose yaba isikhombisa, kusukela ekusungulweni kwayo ngo 1912 kuze kufike ekulimaleni komsebenzi wakhe wezepolitiki ngo 1919. Kuleminyaka eyisikhombisa umsebenzi wakhe kuKhongolose wawubhekene nokugxekwa okukhulu nokubukeka njengomuntu onokuzenza ngcono kunabanye abantu. Emlandweni kaKhongolose uMsane akavezwa ngendlela emfanele, kukhulunywa ngaye kudlulwa nje. Lokunganakwa kukaMsane emlandweni kaKhongolose kusiphoqa ukuba sibhale ngabaholi abangaqakanjiswa. Lolucwaningo luveza umlando kaMsane ngokujulile ngaphezu kwangalesikhathi abizwa khona ngesitha sabantu. Noma umsebenzi kaMsane kuKhongolose wabamfushane kunabanye futhi ugcwele izinto kodwa noko ingobo yawo ikhona. Lolucwaningo lucubungula lengobo ukuhlaziya nokubhala kabusha umlando wengqalabutho eyagcina ishonela ngaphandle kombutho kaKhongolose.

- Description: Abstract This thesis will present an investigation into the variability of the maximum height of the ionospheric F2 layer, hmF2, with hour, season and latitude over the South African region. The dependence of hmF2 on solar and magnetic activity is also investigated. Data from three South African stations, namely Madimbo (22.4 S, 26.5 E), Grahamstown (33.3 S, 26.5 E) and Louisvale (28.5 S, 21.2 E) were used in this study. Initial results indicate that hmF2 shows a larger variability around midnight than during daytime for all the seasons. Monthly median values for hmF2 were used in all cases to illustrate the variability, and the International Reference Ionosphere (IRI) model has been used to investigate hmF2 predictability over South Africa. This research represents the initial steps towards a predictive model for the hmF2 parameter, with the long term aim of developing a new global hmF2 predictive model for the IRI. It is believed that this work will contribute signi cantly towards this aim through the understanding of the hmF2 parameter over a region that has not previously been investigated.

- Description: Space weather and its effect on technological systems are important for scientific research. Developing an understanding of the behaviour, sources and effects of ionospheric events form a basis for improving space weather prediction. This thesis attempts to use co-located radars and instruments for the analysis of ionospheric events over South Africa. The HF Doppler radar, ionosonde, Global Positioning System (GPS) and GPS ionospheric scintillation monitor (GISTM) receivers are co-located in Hermanus (34.4°S, 19.2°E), one of the observatories for the space science directorate of the South African National Space Agency (SANSA). Data was obtained from these radars and instruments and analysed for ionospheric events. Only the Hermanus station was selected for this analysis, because it is currently the only South African station that hosts all the mentioned radars and instruments. Ionospheric events identified include wave-like structures, Doppler spread, sudden frequency deviations and ionospheric oscillations associated with geomagnetic pulsations. For the purpose of this work, ionospheric events are defined as any unusual structures observed on the received signal and inferred from observations made by the HF Doppler radar. They were identified by visual inspection of the Doppler shift spectrograms. The magnitude and nature of the events vary, depending on their source and were observed by all, some or one instrument. This study suggests that the inclusion of a wider data coverage and more stations in South Africa merit consideration, especially since plans are underway to host a co-located radar network similar to that in Hermanus at at least three additional observatory sites in South Africa. This study lays a foundation for multi-station co-located radar and instrument observation and analysis of ionospheric events which should enhance the accuracy of space weather and HF communication prediction.

- Description: The occurrence of mid-latitude spread F (SF) over South Africa has not been extensively studied since the installation of the DPS-4 digisondes at Madimbo (30.88◦E, 22.38◦S), Grahamstown (33.32◦S, 26.50◦E) and Louisvale (28.51◦S, 21.24◦E). This study is intended to quantify the probability of the occurrence of F region disturbances associated with ionospheric spread F (SF) and L-band scintillation over South Africa. This study used available ionosonde data for 8 years (2000-2008) from the three South African stations. The SF events were identified manually on ionograms and grouped for further statistical analysis into frequency SF (FSF), range SF (RSF) and mixed SF (MSF). The results show that the diurnal pattern of SF occurrence peaks strongly between 23:00 and 00:00 UT. This pattern is true for all seasons and types of SF at Madimbo and Grahamstown during 2001 and 2005, except for RSF which had peaks during autumn and spring during 2001 at Madimbo. The probability of both MSF and FSF tends to increase with decreasing sunspot number (SSN), with a peak in 2005 (a moderate solar activity period). The seasonal peaks of MSF and FSF are more frequent during winter months at both Madimbo and Grahamstown. In this study SF was evident in ∼ 0.03% and ∼ 0.06% of the available ionograms at Madimbo and Grahamstown respectively during the eight year period. The presence of ionospheric irregularities associated with SF and scintillation was investigated using data from selected Global Positioning System (GPS) receiver stations distributed across South Africa. The results, based on GPS total electron content (TEC) and ionosonde measurements, show that SF over this region can most likely be attributed to travelling ionospheric disturbances (TIDs), caused by gravity waves (GWs) and neutral wind composition changes. The GWs were mostly associated with geomagnetic storms and sub-storms that occurred during periods of high and moderate solar activity (2001-2005). SF occurrence during the low solar activity period (2006-2008)can probably be attributed to neutral wind composition changes.

- Description: This thesis looks at language as the medium of all our ideas and sentiments. The thesis represents a position statement regarding the development of isiZulu as an academic language. The field of Economics is used to merely illustrate and support the points that are being made in this work. It is argued that each language is viewed as the means of expression of the cultural heritage of its people, and it remains a reflection of cultural groups who speak that particular language. It is a fact that indigenous African Languages have been, for obvious reasons, blatantly understudied during the apartheid years in South Africa (Rudwick 2004). Languages have market value and the desirability of English as the most important global language today has an effect in most Black learners in South Africa. The study examined the development of indigenous African languages, isiZulu in particular, in Zululand University where ninety percent of students and lecturers are isiZulu first language speakers, and came to a conclusion that there is an urgent need for Black South African students to learn academic subjects through their mother tongues. This would help them in thorough understanding and interpretation of analytic text presented in a foreign language such as English. The study advocates that isiZulu, which is the mother-tongue of many students at the University of Zululand, should be a language for upward mobility to these students, but as the situation stands, isiZulu becomes a neglected or marginalised language since it is not the normal medium of instruction and it is not used for effective communication in their education system.

- Description: This mini-thesis investigates the concepts of refusal and rupture as a postdramatic revolt and how these terms can be applied and read within the context of analysing contemporary devised performance in South Africa. The argument focuses on the efficacy of Hans-Thies Lehmann’s postdramatic terminology and the potential of its use in an appreciation of contemporary performance analysis. I investigate the potential in South African contemporary devised performance practice to challenge prevailing modes of traditional dramatic expectation in order to restore the experience of discovery and questioning in the spectator. This research is approached through a qualitative process which entails a reading and application of selected critical texts to the analysis with an application of Lehmann’s terminology. This reading/application is engaged in a dialogue with the interpretative and experiential aspects of selected South African devised performances with particular focus on four cross-disciplinary works selected for analysis. Chapter One functions as an introduction to the concept of postdramatic theatre and the application of the terms refusal and rupture as deconstructive keywords in the process of a devised performance. Chapter Two is an analysis of several South African contemporary performances with particular focus on Body of Evidence (2009) by Siwela Sonke Dance Company, Wreckage (2011) a collaboration by Ubom! Eastern Cape Drama Company and First Physical Theatre Company, Discharge (2012) by First Physical Theatre Company, and Drifting (2013) by The Rhodes University Drama Department. This mini-thesis concludes with the idea that with an understanding of refusal and rupture in a postdramatic revolt, contemporary devised performance achieves an awakening in its spectators by deconstructing the expectation of understanding and the need for resolve; the assumption and need for traditional dramatic structures and rules are challenged. Instead, it awakes an experience of discovery and questioning.

- Description: This mini-thesis investigates the concepts of refusal and rupture as a postdramatic revolt and how these terms can be applied and read within the context of analysing contemporary devised performance in South Africa. The argument focuses on the efficacy of Hans-Thies Lehmann’s postdramatic terminology and the potential of its use in an appreciation of contemporary performance analysis. I investigate the potential in South African contemporary devised performance practice to challenge prevailing modes of traditional dramatic expectation in order to restore the experience of discovery and questioning in the spectator. This research is approached through a qualitative process which entails a reading and application of selected critical texts to the analysis with an application of Lehmann’s terminology. This reading/application is engaged in a dialogue with the interpretative and experiential aspects of selected South African devised performances with particular focus on four cross-disciplinary works selected for analysis. Chapter One functions as an introduction to the concept of postdramatic theatre and the application of the terms refusal and rupture as deconstructive keywords in the process of a devised performance. Chapter Two is an analysis of several South African contemporary performances with particular focus on Body of Evidence (2009) by Siwela Sonke Dance Company, Wreckage (2011) a collaboration by Ubom! Eastern Cape Drama Company and First Physical Theatre Company, Discharge (2012) by First Physical Theatre Company, and Drifting (2013) by The Rhodes University Drama Department. This mini-thesis concludes with the idea that with an understanding of refusal and rupture in a postdramatic revolt, contemporary devised performance achieves an awakening in its spectators by deconstructing the expectation of understanding and the need for resolve; the assumption and need for traditional dramatic structures and rules are challenged. Instead, it awakes an experience of discovery and questioning.
