- Description: The physicochemical properties of two bioflocculant producing bacteria; Halomonas sp. Okoh and Micrococcus sp. Leo were investigated. The optimum culture conditions for the individual species were determined. All the growth conditions examined for the individual bacteria were similar. Glucose and ammonium sulphate as sole carbon and nitrogen sources respectively resulted in optimum production of bioflocculant. The flocculating activity of the bioflocculants was stimulated when Al3+ was used as the coagulating aid under acidic medium. The information obtained from individual strains was used to produce a bioflocculant from the consortium of the two bacteria. After purification, the bioflocculant yields from 1L fermentation broths were 1.213 g from Halomonas sp. Okoh, 0.738 g from Micrococcus sp. Leo and 3.51 g from the consortium. The chemical analyses of the purified bioflocculants showed that they were glycoproteins. The thermostability property of the bioflocculants was investigated between 50-100oC and the results revealed that they are heat-stable. Fourier transform infrared revealed the presence of hydroxyl, carboxyl and amino groups in the bioflocculant molecules. Scaning electron microscope (SEM) images showed the structure of each bioflocculant(s) and kaolin clay before and after flocculation. From the results obtained, the idea of using the two strains in consortium for bioflocculant production resulted in an improvement in terms of flocculating activity and yield. The bioflocculants appears to have promise as an alternative to chemical flocculants used in various industrial processes such as wastewater treatment and drinking water purification. , Thesis (MA) -- Faculty Science and Agriculture, 2013

- Description: The prevalence of allergic diseases has dramatically increased over the last three decades. Presently, it is estimated that 20-30 per cent of the developed world suffers from allergic diseases. The majority of allergic diseases are rooted in the activities of IgE; an immunoglobulin which exerts its effector functions by interacting with a network of proteins. This network includes its low affinity receptor CD23. Cross linking of membrane IgE and CD21 by soluble CD23 results in an increase in IgE synthesis. This marks the interaction between CD23 and CD21 as an attractive therapeutic target. However, details regarding this interaction are inadequate for rational drug design. To obtain a deeper understanding of the CD23-CD21 interaction recombinant human CD21 (SCR1-2 and SCR5-8) and CD23 (16 kD and 25 kDa) were produced. The cloning, expression and purification of recombinant proteins comprised a significant portion of this study. Recombinant CD23 was expressed as inclusion bodies, refolded by rapid dilution and purified by size exclusion chromatography. Conversely, recombinant CD21 was expressed as soluble MBP-fusions and purified with an amylose affinity resin. The interaction between recombinant CD23 and CD21 was analysed by flow cytometry and ELISA experiments. Flow cytometry showed that 16 kDa and 25 kDa CD23 interacted with SCR5-8 to the same extent. Semi-quantitative ELISA experiments showed that both SCR1-2 and SCR5-8 were able to interact with 16 kDa and 25 kDa CD23. This suggests that the binding sites of SCR1-2 and SCR5-8 occur on 16 kDa CD23. Furthermore, since proteins were expressed in E. coli it suggests that the CD23-CD21 interaction does not require glycosylation. Furthermore, considering what is known about the SCR1-2-CD23 interaction from previous NMR studies; i.e. that the C-terminal tail (residues residues 289-298) of CD23 is responsible for binding SCR1-2, indicates that SCR5-8 binds somewhere within the lectin domain of CD23. This indicates that the CD23-CD21 interaction involves C-terminal tail-SCR1-2 and lectin domain-SCR5-8 interactions.

- Description: The focus of the study was to explore and describe reasons for poor professional behaviour among nursing students at a public nursing college in the Eastern Cape. The objectives of the study were to explore and describe the reasons for poor professional behaviour among nursing students and to describe strategies to improve poor professional behaviour. The study has significance for the college management, staff, nursing students, registered nurses and everyone involved in professional development of nursing students. The population for this study consisted of third-year nursing students following the four-year comprehensive basic course for registration leading to the Diploma in Nursing (General, Community & Psychiatry) and Midwifery at a public nursing college. The research questions were: What do you understand by professional behaviour? What are the reasons for poor professional behaviour among nursing students? What could be done to improve professionalism among college nursing students? A qualitative, explorative, descriptive and contextual design was used as a framework for the study. Permission to conduct the study was obtained from the University of Fort Hare ethics committee and other relevant authorities as indicated in the study. Ethical principles were maintained and informed consent obtained. Data collection was done using focus groups and an audiotape with a purposefully sampling of 30 third-year nursing students at the public college of nursing. Data were analysed using Tesch’s method of analysis for qualitative research. Three major themes emerged: students’ understanding of professional behaviour, reasons for poor professional behaviour and methods to improve poor professional behaviour. It was concluded that poor professional behaviour has an effect on professionalism and it should be addressed and corrected for protecting the professional image. Recommendations: Policies regarding inappropriate professional behaviour at the college should be in place and easily accessible to every staff member and nursing student. Department of Health should conduct reflective courses and seminars on professionalism and these should begin at the same time as the academic programme.

- Description: The thesis focuses on ‘green’ sample preparation techniques that utilise minimal or no organic solvents thereby producing negligible volumes of organic waste, to ensure safety both to user and the environment. Volatile compounds were extracted and pre-concentrated from Kgalagadi desert truffles (kalaharituber) by headspace solid phase microextraction (HSSPME) and supercritical fluid extraction (SFE). PHWE was employed for the extraction of amino acids and fatty acids. Subsequent analysis of volatile compounds was carried out by gas chromatography coupled with mass spectrometry. Four types of HS-SPME fibers (PDMS 100 μm, PDMS 7 μm, Polyacrylate 85 μm, CAR/DVB/PDMS 50/30 μm) were evaluated. A total of 24 volatile compounds with a molecular weight range from 110 to 354, the most prominent peak being 2-t-Butyl-2,3-dimethyl-3-buten-1-ol (C₁₀H₂₀O, MW 156) were detected after sampling with a PDMS 100 μm fiber. Less volatile compounds were detected after SFE with CO2. A total of 16 amino acids were identified while 17 fatty acids (MW from 132.12 to 367.49) were also identified. The characteristic profile of the Kgalagadi desert truffle was found to contain mainly fatty acid methyl esters and unsaturated aliphatic hydrocarbons. The most prominent compound peaks identified were; 2-t-butyl-2,3-dimethyl- 3-buten-1-ol, disulfide, ethyl benzoic acid 2-4-dhydroxy-3,6-dimethyl-methyl ester, 8,11- octadecanoic acid methyl ester, benzoic acid, 2,4-dihydroxy-3,6-dimethyl-methyl ester, isoquinoline, 1 butyl-3,4-dihydro and 3-heptanone, 6 methyl. Optimization results indicated that fresh slices from the heart of truffles were the best to use for HS-SPME-GCMS volatile compound analysis as they showed a higher sensitivity

- Description: Effective leadership is essential for the achievement of any organisational success. The need for strong leadership and increased diversity is a prominent issue in today’s health service workforce. Effective leadership involves influencing others towards achieving the goals of the organisation. Leadership is the central ingredient necessary for progress as well as for the development and survival of organisations, especially in a changing environment such as is evident in South Africa. This study was undertaken to explore and describe the views of health professionals with respect to factors that promote or influence leadership effectiveness in public hospitals, with specific reference to Uitenhage Provincial Hospital. The research design of this study was a quantitative, explorative, descriptive survey. Interviews were conducted to explore and describe the views and perceptions of healthcare professionals (clinical and nonclinical), and the management of the Uitenhage Provincial Hospital, regarding leadership effectiveness in a public hospital. Firstly, a literature study was conducted on healthcare leadership generally and to identify various leadership approaches and factors that influence leadership effectiveness. More emphasis was put on the current and the most recent approaches to leadership. Secondly, an empirical study was conducted to gain the views and ideas of health professionals regarding leadership effectiveness in the institution. Lastly, the results of the empirical study were evaluated, conclusions were drawn and recommendations were made, based on the information obtained from both the literature study and the empirical study.

- Description: The use of many of South Africa’s medicinal plants has shown marked increase with over 27 million users in South Africa alone. Most plants are still being unsustainably wild-harvested, a major concern for biodiversity conservation. Commercial interest in certain more commonly-used species has increased, with potential to cultivate medicinal plants on a more sustainable basis. Focus has shifted from conventional use of synthetic fertilisers, pesticides and fungicides to more organic methods of plant propagation. Aqueous extract derived from earthworm composted food waste (vermitea) was used to study the germination and rooting success of selected species. Also survival and growth performance of selected plants grown in a medium amended with commercial NPK fertiliser was compared to those grown in the same medium amended with compost and to those grown in the same medium amended with compost with weekly applications of vermitea. No change in germination success was noted. Vermitea showed promising results on the rooting of cuttings. The application of NPK improved growth performance (biomass) significantly for all species tested. However, they had lower root:shoot ratios as well as lower survival rates compared to plants under the compost and compost/vermitea treatments. The improved survival of these plants highlights the potential of these organic treatments on the propagation of selected medicinal plants.

- Description: Although it is generally acknowledged and accepted that case formulations are useful in psychotherapy treatment, there is significantly little research illustrating how case formulations are useful in treatment. Research also suggests that case formulations are seldom used in practice after initial training (Eells, 1997; Sim, Gwee, & Bateman, 2005). This research was premised on a particular case study which appeared to highlight shifts in psychotherapy treatment in the sessions directly after the writing or revising of the case formulation, thus prompting the inquiry into the influence of the case formulation on therapeutic work. The research utilised a qualitative methodology and focused on a single case which was a 19 year old university student who expressed a problem with binge eating. The data was drawn from five original and revised case formulations. The participant was seen for 27 therapy sessions, over which time five case formulations were developed and revised. The findings in this study highlight the process of how a psychodynamic case formulation can influence therapeutic work, as reflected in three broad themes of adherence to the case formulation, the confidence of the therapist, and using the formulation as an intervention. The study contributes to arguments for the revival of the case formulation as a necessary therapeutic tool. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

The study contributes to arguments for the revival of the case formulation as a necessary therapeutic tool. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: This research project mainly focuses on the public financial accountability in the Ministry of Finance and Economic Planning for South Sudan. According to the Public Service Regulations, the government has a duty and responsibility to deliver services to its entire people. In other words, the government exists primarily for the welfare of the people, by creating public institutions to render services delivery and developmental programmes for the communities. There are no government institutions that can function without the provision of finance resources (money). The management of the finances is one of the most important and critical tasks of the government, which requires public financial accountability from the political role-players and public officials, concerned with the use of public money (to be accountable). However the level of service delivery that citizens have to expect depends mostly on standardized public financial accountability of public money (revenue income) by the role players, and public officials in the institutions as integral part of public financial management. Any organization that manages and reports on its finances mitigates the risk of finances, builds good quality and openness into its financial and non financial analyses, monitors the sustainability of benefits and reflects sound financial accountability. Public financial accountability is a specific field that intended to as a tool use for the economy, efficient and effective administration of public money for render of service delivery to the citizens and the developmental programmes for the better live condition or general welfare of the communities. The study was motivated by the issue of public financial accountability in the Ministry of Finance and Economic Planning for both, during the interim period of six years and after independence in, 2011 for the government of South Sudan which has influenced socio- economic concern, as a result many communities in South Sudan have no access to basic services delivery. Research instruments which solicited quantitative and qualitative data were used to collect information from a sample of management officials and administrative staffs within the Ministry of Finance and Economic Planning The research sought to identify the challenges faced and their causes and the ways of improving efficiency and effectiveness of public financial accountability in the ministry of finance and economic planning. The focus of public financial accountability is ranging from the stages of revenue collection, keeping/saving, treasury regulations, money transfer and budget expenditure, etc that can be achieved by transparency, financial reporting statements, control, and audit, as well as good ethical behavior for good performance in the public institutions, this is because maladministration practices of public finance have an impact in rendering of service delivery’s performance. This research focuses on the level of preparedness for accountability and financial accountability with regard to public financial management in the Ministry of Finance and Economic Planning. Particularly, it explored the laws, policies, procedures, rules and regulations governing implementation of public money, systems in place to oversee this process as well as the capacity of the role-players and public officials in this respective ministry. It further examined how finances have been used for the rendering of service delivery to the communities. In order to accomplish the objectives of this study, a literature study as well as empirical research was undertaken. For the empirical research, questionnaires as well as various types of interviews were used. For proportionate representation efficiency as well as cost effectiveness, the research used a sample of 26 respondents. These included 6 Financial Management Officers, 4 Directors General, 14 finance administrative Staffs, 1 Auditor-General, 1 Chair Person of Anti-Corruption Commission Exploratory statistics and methods were utilized to analyze the data collected so as to measure the reaction to the research questions and objectives under scrutiny. The research disclosed that the public financial accountability in the Ministry of Finance and Economic planning is a new approach that facilitates changes and growth by improving the ways of control public money. The study also found that the standardized laws, policies rules and regulations, and procedures for implementation for public financial accountability have been developed, but not implemented to achieve the stated goals. Also some other important documents are not yet developed. The findings attested to recommendations that, this research will help the policy makers to reformulate the policy; help the implementers or administrators the planners or the managers of the programmes to modify or adjust the programme; to help professionals or academician including those who may research in the area or field; it will help in filling gap in that particular academic dimension or field. The study made recommendations that, the public financial accountability must be improved in the ministry of finance and economic planning, through standardized policies and structures, procedures, transparent and accountable, financial reporting statements and control pertaining to public money. There is a great need for further research in this area of public financial management. This may not be restricted to the Ministry of Finance and Economic Planning only but to all other state ministries where the utilization of public money has already been established.

- Description: Post conflict justice is a concept that has in the last two decades gained notoriety and support across the world. The commitment by states to fight impunity by embracing accountability measures has increasingly gained support. This however, was not always the case. Before the 1980s the approach by most of the world was to turn a blind eye to serious violations committed during wars, insurgencies and serious conflict. This was done in the name of respecting state sovereignty, where other states were required to respect the conflict state by not intervening irrespective of egregious violations being committed to mankind. The tide eventually changed and many states have adopted numerous instruments as a sign of their commitment to fight impunity and bring accountability to the perpetrators of serious conflict. African states embraced this development, in 1998 during the Rome conference where the Rome Statute for the International Criminal Court was adopted. African states participated in large numbers during the negotiations. Subsequently, African states signed and adopted the Statute overwhelmingly. To date, 33 African States have ratified the Rome Statute making Africa the most represented region in the Rome Statute system. With Africa's share of countless conflicts, where serious human rights violations have been violated, post conflict justice is increasingly a reality in Africa. The application of post conflict justice is an emerging and ever evolving field in Africa. The implementation of post conflict justice has been the center of contested debates. These debates have in the recent past become more pronounced especially where international intervention has been applied in assisting African post conflict societies to deal with the past and bring accountability. The impact that the accountability mechanisms play in restoring a post conflict society has been overshadowed by these debates. This study therefore seeks to provide a balanced discussion on the role that the accountability mechanisms can play in African post conflict societies. The study gives an overview of the evolution of post conflict justice and also looks into the different post conflict justice approaches adopted by African countries and their potential role in accountability and societal healing. The empirical cases of South Africa and Kenya are analysed in the study as practical examples of the application of post conflict justice approaches. The impact of the accountability mechanisms adopted is also discussed. The unique role that the African Union plays in fighting impunity in the continent is also discussed and the impact of positions taken by the continental body on accountability in post conflict countries is analysed. In the end the study seeks to establish the growing pattern in Africa in dealing with post conflict situations and recommendations are made in the final chapter on how to improve the general approach by Africa to eradicate the culture of impunity for serious crimes committed in the continent.

- Description: The entertainment education (E-E) strategy has gained currency in development communication scholarship and praxis. However, the theoretical treatment of the strategy has mostly emphasised questions of effectiveness thereby paying minimal attention to substantial resistances encountered at the message reception level. This study investigates the praxis and reception of the E-E television drama Tsha Tsha. It uses the Cultural Studies approach and reception theory to explore the consumption of Tsha Tsha by subaltern black South African youths located within specific socio-historical contexts. Audiences’ negotiated readings were used to critique the assumption that E-E messages are ‘unproblematically’ received by target audiences. Tsha Tsha’s E-E strategy and its theoretical and methodological inputs were also appraised with a view to locating the intervention within the trajectory of E-E and development communication interventions. The emerging insights were critical in understanding whether contemporary E-E interventions have transcended modernisation practice. While the focused synthesis approach, consisting of qualitative content analysis, document analysis and literature review, was used to evaluate Tsha Tsha’s use of the E-E strategy, reception analysis comprising of focus group discussions and follow up in-depth interviews with selected subaltern black South African youths was employed to explore viewers’ social production of meaning from the media text. This process enabled the study to identify the locus of meaning between the two contenting poles: the media text and situated readers. The study’s findings indicate that some contemporary E-E interventions have transended ‘modernisation practice’. Their conceptual and methodological approaches have embraced the central tenets of communication for social change. The results from the reception study also clearly indicated that E-E enterventions face resistances in subaltern discursive spaces. Situated readers’ negotiation of Tsha Tsha showed that viewers are not passive readers of E-E texts. Rather they are engaged in an ongoing process of re-interpreting and resisting the ‘preferred text’. Audiences situated discourses and lived experiences at times provided alternative frameworks through which the ‘dominant meanings’ were re-interpreted and even opposed.

Reactions towards the synthesis of the uncommon P57 cymarose moiety

- Description: The work described in this study aims to investigate methods that will improve a lengthy synthetic pathway in the synthesis of the P57 cymarose moiety, and to examine the conformational structure of certain glycosides in order to shed light on the problematic stereochemical issues surrounding the formation of the cymarose glycosyl donor. The cymarose moiety forms part of the trisaccharide derivative present in P57, an appetite suppressant molecule. Modification of reaction steps in the conversion of the stereochemistry at C-3 of a previously reported synthesis of the P57 cymarose moiety was carried out. The first step was the selective oxidation of D-glucal using Pd/C in the presence of acetonitrile. These reaction conditions are more appropriate for the oxidation step to avoid decomposition of the formed molecules. Successive protection of the free OH groups was followed by NaBH4 reduction under stereo-controlled conditions, influenced by CeCl3•7H2O. However, the reduced product could not be isolated from the starting material and this led to ambiguous results when attempting to confirm whether the conversion of the stereochemistry at C-3 had occurred or not. The effect of reaction conditions, such as change in reaction temperature, during the preparation of the cymarose glycosyl donor was studied in order to find suitable reaction conditions to produce α,β-allo derivatives with high stereoselectivity. Compared to the reported synthetic method, this set-up gave improved yields with, unfortunately, similar or slightly lower selectivity to the formation of α-altro:α,β-allo derivative. Examination of the conformational structure of the allal derivative, in order to understand the mechanism at work during the placement of the directing group at C-2, was carried out using molecular modelling. The mechanistic implications of this very short study are discussed and it provides some insights into the likely pathway of the iodination reaction and its selectivity in particular, to the D-allose system.

- Description: The feasibility of capital projects in an uncertain world can be determined in several ways. One of these methods is real options valuation which arose from financial option valuation theory. On the other hand fuzzy set theory was developed as a mathematical framework to capture uncertainty in project management. The valuation of real options using fuzzy numbers represents an important refinement to determining capital projects' feasibility using the real options approach. The aim of this study is to determine whether the deferral of the decommissioning time (by a decade) of an electricity-generating nuclear plant in South Africa increases decommissioning costs. Using the fuzzy binomial approach, decommissioning costs increase when decommissioning is postponed by a decade whereas use of the fuzzy Black-Scholes approach yields the opposite result. A python code was developed to assist in the computation of fuzzy binomial trees required in our study and the results of the program are incorporated in this thesis. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: Network telescopes and honeypots have been used with great success to record malicious network traffic for analysis, however, this is often done off-line well after the traffic was observed. This has left us with only a cursory understanding of malicious hosts and no knowledge of the software they run, uptime or other malicious activity they may have participated in. This work covers a messaging framework (rDSN) that was developed to allow for the real-time analysis of malicious traffic. This data was captured from multiple, distributed honeypots and network telescopes. Data was collected over a period of two months from these data sensors. Using this data new techniques for malicious host analysis and re-identification in dynamic IP address space were explored. An Automated Reconnaissance (AR) Framework was developed to aid the process of data collection, this framework was responsible for gathering information from malicious hosts through both passive and active fingerprinting techniques. From the analysis of this data; correlations between malicious hosts were identified based on characteristics such as Operating System, targeted service, location and services running on the malicious hosts. An initial investigation in Latency Based Multilateration (LBM), a novel technique to assist in host re-identification was tested and proved successful as a supporting metric for host re-identification.

- Description: The focus of this study was to explore reasons for the failure of student nurses to present themselves for assessment of clinical skills at a public nursing college in the Eastern Cape. The objectives were to explore and describe reasons why these student nurses were not presenting themselves for such assessment of clinical skills; to develop strategies to motivate them to present themselves for clinical skills assessment; and to make recommendations for assessment of clinical skills. The population of the study was the second and the third-year student nurses undergoing a four-year comprehensive diploma course at a public college of nursing in the Eastern Cape. Non-probability convenience sampling was used. The research questions were, firstly, why the student nurses were not presenting themselves for assessment of clinical skills? Secondly, what recommendations could be made to motivate the student nurses to present themselves for clinical skills assessment? A qualitative, explorative, descriptive and contextual research design was used. Focus group interviews with six participants per group were used to collect data. The total number of participants five focus groups was 30 by the time data saturation was reached. Data were collected following the research question, “Why are you not presenting yourselves for clinical skill assessment?” Their responses were recorded using audiotape and notes with the help of an experienced colleague. Data was analysed following Teschʼs method. Findings presented one theme, being the reason for students not presenting themselves for feedback or delaying to do so. Categories indicated that students were afraid and overwhelmed with anxiety; had too much work to do; unpreparedness for learnt skills; equipment and resources; lack of confidence; and busy ward schedules. Subcategories included lecturersʼ attitude; unfamiliarity to lecturers accompanying them; having to study to master a lot of theory; having to prepare for many tests; unavailability of lecturers to mentor them; unavailability of unit professional nurses to guide them; reluctance of patients to be used for practising skills; a tendency not to practise skills; too many students; being used as work force; placement objectives; use of dolls for demonstration; tools used to support learning making reference to obsolete equipment; all skills demonstrated at the same time; lecturers improvising when they are demonstrating some skills, and not being released for practising of skills. The focus of this study was to explore reasons for the failure of student nurses to present themselves for assessment of clinical skills at a public nursing college in the Eastern Cape. The objectives were to explore and describe reasons why these student nurses were not presenting themselves for such assessment of clinical skills; to develop strategies to motivate them to present themselves for clinical skills assessment; and to make recommendations for assessment of clinical skills. The population of the study was the second and the third-year student nurses undergoing a four-year comprehensive diploma course at a public college of nursing in the Eastern Cape. Non-probability convenience sampling was used. The research questions were, firstly, why the student nurses were not presenting themselves for assessment of clinical skills? Secondly, what recommendations could be made to motivate the student nurses to present themselves for clinical skills assessment? A qualitative, explorative, descriptive and contextual research design was used. Focus group interviews with six participants per group were used to collect data. The total number of participants five focus groups was 30 by the time data saturation was reached. Data were collected following the research question, “Why are you not presenting yourselves for clinical skill assessment?” Their responses were recorded using audiotape and notes with the help of an experienced colleague.

The researcher concluded that students had valid reasons for not presenting themselves for assessment of clinical skills but this could be rectified through the involvement of lectures, ward staff as well as students themselves. The researcher recommended that effective communication between the staff in clinical areas and the college is needed. Clinical laboratories needed laboratory managers and had to be well equipped. A revision of the student-lecturer ratio form feed-back on skills is also suggested.The researcher concluded that students had valid reasons for not presenting themselves for assessment of clinical skills but this could be rectified through the involvement of lectures, ward staff as well as students themselves.

- Description: This study sought to reconstruct the history of Lantana invasion and spread in India by considering two questions; (a) from where, by who, and when were Lantana species introduced into India? and (b) given its long history in the country, is it still spreading or more or less stable? We critically evaluated the archival and historical information on plant imports by the European powers into India during the period before and after British colonization. We then reconstructed the path of spread by analyzing the spatio-temporal patterns of occurrence and distribution of Lantana in India at both the national and local scale using a GIS platform. The spread of Lantana across the globe started as early as the 1690s. The European colonial powers moved the plants from Latin America to Europe and to their colonial countries in the early 1800s. Lantana species were introduced in India from 1807 onwards and thereafter the colonial powers moved this plant across the country. Following its introduction into India, the spread of Lantana across the country, either through subsequent multiple introductions from Europe to different British cantonments, or through moving the plants between cantonments within India, were reasonably rapid spanning only a few decades. In the absence of a rigorous control program, the spread of Lantana has gone on unabated and thereby impacting both wildlife and biodiversity.

- Description: This research sought to understand the perceptions of the township dwellers who are the beneficiaries of the RDP houses in a selected township, Chris Hani block 3 in Mdantsane, East London, in the Eastern Cape. The study specifically sought to establish whether the houses delivered to the residents through the Reconstruction and Development Programme (RDP) adequately meet the basic standards prescribed by the relevant housing policy of South Africa. During the apartheid era black South Africans were marginalised, their development was separate from that of whites and they had no say in what was provided for them, hence they were inadequately housed. On coming into power, the post-apartheid government undertook through legislation to provide sustainable, adequate housing that would address the needs of the historically disadvantaged citizens/poor people of South Africa. The main finding of this study conducted on a sample of ten RDP housing beneficiaries, through personal interviews is that, the RDP is a good programme; however, its implementation is characterised by corruption and greed. The people, whom the programme is meant to benefit, have never been involved in their own development with the results that the houses provided to them, are of a sub-standard quality. The houses do not adequately address the housing needs of the people. The housing policies are also not adequately implemented. It is the author’s hope that the recommendations made by this study, if implemented, will improve the standard of the RDP houses provided to the poor people of South Africa.
