- Description: An important focus of peacebuilding as a part of post-conflict reconstruction is the provision of basic needs. Peacebuilding is a move from war to a peaceful future. Peacebuilding rests on the premise that provision of people’s needs eliminates unrest and lawlessness that arise due to war. This in turn prevents a relapse into war. Also, communities that experience war lose many years and tend to develop at slower rates than peaceful areas, if at all they do develop. The twenty year old war in Northern Uganda has caused a gap between this area and the rest of the country. Poverty has left many unable to provide basic needs. Peacebuilding efforts have been undertaken by Non Governmental Organizations, Community Based Organizations, Government of Uganda as well as people in the community organizing themselves into groups to enable them reconstruct their lives. Efforts are being made towards reconstruction, resettlement, reconciliation and providing relief in an effort to move from war and destruction. In many societies, women are left out, marginalized and discriminated against as a result of patriarchy. Their roles in peacebuilding are not considered important and they face many challenges in their efforts to rebuild their lives and families. This research focused on the challenges faced by women in Gulu, a district in the Northern region of Uganda in peacebuilding. Through conducting face to face interviews, and consulting documents available to the public, the researcher collected information about the challenges faced by the Acholi women, the women of Gulu district.

- Description: This research sought to investigate the problems experienced in the interpretation of word problems by senior secondary school learners, in particular to see how the language used in the articulation of word problems affects the interpretation. The study was conducted in a school in the Oshikoto region of Namibia, a school located in a semi-rural area of Namibia, and selected owing to the accessibility of the required participants. The research was located within an interpretive paradigm focusing on a study sample of 40 learners from a specified class in the selected school. Data were collected through written tests and a semi-structured interview based on written tests, and a comprehensive descriptive analysis of test results was prepared. The findings of the study indicate that the language in which the word problem was articulated did not make a difference. The performance in both English and Oshindonga tests was almost the same. The findings also indicate that vocabulary, syntactic interpretation, semantic relationships, algebraic skills, and practical sense making in relation to real-life are all important for the successful interpretation and solving of word problems. In view of these findings, the study has provided valuable insights into aspects of the teacher education curriculum that need to be revisited in order to improve the training of teachers In teaching word problems.

- Description: Conflict in Africa remains one of the continent’s principal development challenges. The human, economic and development costs of conflict are immense. A peaceful and secure environment remains the greatest priority for ordinary Africans across the continent. However, this often remains a mirage for many as violent armed conflicts continue to take its toll on many ordinary citizens, often, displacing them as refugees. Some refugees remain in very a deplorable refugee camps that offer them no prospects of decent livelihood for many years. With fear that they would be persecuted upon return to their countries of origin and often the delays in finding solutions to political violence, refugees remain in a protracted situation. A Protracted refugee situation means that refugees have lived in exile for more than five years with no immediate prospect of finding a durable solution to their plight by means of voluntary repatriation, local integration or resettlement. Thousands of refugees who fled violent conflicts in the West Africa and other parts of Africa have lived for more than a decade in the Krisan and Buduburam refugee camps in Ghana. A situation that can be termed protracted. This paper investigated the perceptions of local Ghanaians, Refugees of Krisan Refugee Camp and Government Official on the integration of refugees in Ghana. Krisan Refugee Camp which was built in 1996, particularly, houses about 1,700 refugees from nine countries: The Democratic Republic of Congo, Congo Brazzaville, Côte d’Ivoire, Chad, Liberia, Sierra Leone and The Sudan. The refugees have lived with the indigenous people of Krisan village for more than a decade and thus offered the best case for the investigation. The researcher used qualitative triangulation method to collect data. That is, he observed the refugees, the local people and supervisors of the refugee camp who made up the sample population. The researcher was able to conduct a face to face in-depth interview and studied necessary documents that informed the study immensely. Thematic data analysis revealed economic and employment opportunities, security, cultural and social networking and finally good counselling on the three traditional durable solutions as the themes greatly impacting on the integration of refugees in Ghana. A number of recommendations are made to inform the management and integration of refugees in Ghana and in Africa in general.

- Description: This research study explores in general the nature of a private general medical practice [PGMP] and whether analysis of the PGMP as a social system can lead the Group Dynamics Practitioner towards developing interventions that will enhance group effectiveness in the PGMP support staff group. The main assumption is that, through the application of a framework of analysis based on that of G. C. Homans and the AGIL functional prerequisites developed by T. Parsons, a structured analysis of the external and internal variables that impact on the PGMP as a social system can be undertaken. The findings of the analysis would lead to the formulation of interventions that would improve the performance effectiveness of the PGMP as a social system. Following a two-questionnaire survey of 17 practices that provided demographic information as well as soft skills training needs, a single PGMP was identified for the case study. Data pertaining to the group as a social system were collected, and by using direct observation, content analysis and a sociometric test, the practice support staff sub-system, being the main focus of this research, could be analysed. By linking the findings to the elements of the framework of analysis, areas of ineffective group functioning could be identified and interventions suggested. This research indicates that the choice of soft skills is associated with the nature and size of the practice, as well as the dynamics of the sociometric patterns characteristic of the relations within the practice support staff subsystem; that while some practice support staff have preferences for sociometric task and socio-emotional relations outside their work clusters, these seem to serve as a buffer against clique forming, thus enhancing the function of integration within the social system as a whole; and that the physical practice layout, and the interaction dynamics that it creates, tend to hinder integration between the members of the practice support staff group, as a social subsystem.

- Description: The aim of this study was to explore the roles of the parent SGB members in the School Governing Bodies (SGB) of two selected rural primary schools in the King Williams Town District. This was achieved by applying the qualitative approach within the parameters of the interpretivist paradigm. Structured interviews, semi structured interviews, document analysis and non-participatory observation methods were used at two sites that were purposely sampled. The samples in both schools were made up of SGB chairperson, SGB secretary, treasurer, one additional member, principal and non SGB parents. From the findings it emerged that the principal and SGB chairperson work in partnership in the business of school governance. However, principals seemed to dominate their SGB chairpersons who in most cases seem to be less competent than the principals. Parent SGB members seem to be dependent upon the educators in most cases on issues of school governance and they do not differentiate between their role and that of the SMT. Most SGB subcommittees seem to be dysfunctional and it was clear from the data that educators were the persons who dealt with school finances and matters of procurement. The majority of parent SGB members do not know what policies the school must adopt.

- Description: A healthy democracy is generally seen as one in which citizens participate regularly in formal political activities. Citizens’ participation in governance has come to be accepted as an expression of their rights and the manifestation of citizen agency. Access to information remains a crucial component of the right to participate. Transparency, as a normative and constitutional value, represents a means, not an end. The means is the mechanism of access to information. Within the South African context, there is evidence of an increase in participation of a variety of interest groups by means of different processes, as well as through the establishment of numerous consultative bodies and mechanisms for popular participation at all levels of the political structure (Houston, 2001:1). However, accountability to citizens can best be gauged by assessing citizens’ opportunities to influence legislation between elections. Ultimately, the effectiveness and sustainability of mechanisms aim at improving citizens’ participation in policy formulation in order to become effective when they are “institutionalized” and when the state’s own “internal” mechanisms are rendered more transparent and open to civic engagement. Furthermore, the success depends on some form of effective interaction between the state and civic society. In the case of South Africa, whilst the political context and culture for participation exist in the form of the constitutional provisions and several pieces of legislation, a discrepancy exist whereby many South Africans are excluded or devalued by the vast differences in wealth. Citizen’s votes may count equally, but they are still not able to participate on an equal basis between elections. Participatory mechanisms established to ensure citizen’s participation, access to information and monitoring inside and outside the legislature, remain ineffective. These unequal opportunities mean that the poorer and less organised segments of society are prejudiced in terms of influencing legislation and policy. Their lack of full and meaningful participation means legislative outcomes are less representative of, and responsive to, the interests of the poorer segments of society (Habib, Shultz – Herzenberg, 2005: 144). The focus of this study is limited to the province of KwaZulu-Natal. The aim is to, firstly, assess the extent to which citizens can control those who make collective decisions about public affairs. Secondly, it assess the extent to which citizens participate in the existing participatory mechanisms, and thirdly, the study explores the possibilities of the synergy between the state and civil society in promoting effective participation by its citizens. The study, therefore : 1. Assess the theoretical and policy framework for citizen’s participation in South Africa; and 2. Evaluate the level of participation and effectiveness of participatory mechanisms inside and outside the KwaZulu - Natal Legislature. The study introduces the theoretical and conceptual framework of citizen participation through a literature review; followed by an empirical study of citizen participation in the legislative process in the kwaZulu Natal legislature. The study makes the following findings: 1. The literature review concurs that South Africa has one of the most progressive and liberal constitutions in the world. This is coupled with a sound policy framework demonstrating genuine political will for citizens’ participation in policy formulation. 2. Within the political context and culture for citizen participation, the main question of how much control citizens have over the actions of their government remains. Another issue is whether existing mechanisms in the legislature are effective in engendering citizen’s participation and quality input in public policy – making processes. 3. The study showed that ultimately the effectiveness and sustainability of citizen participation mechanisms is improved when they are “institutionalised” and when the state’s own internal mechanisms of accountability are rendered more transparent and open to civic engagement. The study also highlighted the need for synergy between the state and civil society. This includes, among other things, participatory budgeting, public expenditure tracking, monitoring of public service delivery, investigative journalism and citizens’ advisory boards. The study, therefore, makes two recommendations: 1. A comparative Citizens Education and Outreach Programme be developed and spearheaded by both the legislature and civil society in kwaZulu-Natal; and 2. A further study needs to be undertaken to investigate the possible structural nature of the synergy (relationship) between the state and civil society in the province.

- Description: South Africa's HIV prevalence rate is estimated to be 5.7 million and at the end of2007 a total of 45845 HIV/AIDS adult patients were taking antiretroviral therapy (ART). The global incidence of HIV/AIDS has been slowly decreasing over the years but is still widespread. This disease is still more prevalent in sub-Saharan Africa than in other parts of the world, with more than 60% people living with HIV/AIDS. Highly active antiretroviral therapy (HAART), the treatment of choice, slows the progression of the human immunovirus but demands a high adherence rate in excess of 95%. Patients who are poorly informed about antiretrovirals (ARVs) and misunderstand medicine-taking instructions or experience unexpected side effects may interrupt therapy, predisposing them to the development of resistance. Such patients need information but, given the poor literacy skills prevalent in South Africa, written information is often not fully comprehended and is often written at too high a reading level. The objectives of this research project were to design, modify and evaluate HIV / AIDS patient education materials for low-literate isiXhosa speaking adults residing in Grahamstown and to examine their impact on the understanding of various aspects of the disease and its treatment. Pictograms illustrating common side effects of ARVs (e.g. stavudine, efavirenz, lamivudine), as well as various sources 'for purchasing nonprescription medicines, storage and medicine-taking instructions were designed and evaluated both qualitatively, using group discussions, and quantitatively through individual interviews where interpretation of the pictograms was assessed. These pictograms were incorporated in a patient information leaflet (PIL) which had been specifically designed for people with limited reading skills and was a simple document containing the minimum of essential text. A previously developed PIL was modified in collaboration with the target population and two versions were produced, one incorporating pictograms illustrating side effects, the other with none. Pictograms were used in both to illustrate other medicine-taking instructions. The PILs were tested objectively to assess the readability, format, content, and general design. They were translated into isiXhosa prior to being qualitatively and quantitatively evaluated in a low-literate isiXhosa speaking population. Understanding of the PILs was assessed by asking a series of questions about the PIL content. Participant opinion of the readability and appearance of the PIL was recorded. The relationship between PIL understanding and selected demographic variables was investigated. Findings from this study illustrated that well designed pictograms assist in the location of information in written leaflets and they may enhance understanding of the information. It was further demonstrated that education influences total understanding of PIL content thus emphasizing the need for tailor-written information in accordance with the education level of the target population. A desire to receive PILs incorporating pictograms was expressed by the majority of participants. Collaboration with the intended target population is essential to design culturally acceptable, easily interpreted pictograms and to produce user-friendly, easy-to-read, comprehensible patient education materials. The rigorous, iterative design, modification and testing process described in this study is one that should be adopted in producing all health-related education materials.

- Description: Standard economic models often emphasize inputs, outputs and an examination of the structures in order to conduct an economic performance evaluation. This study applies the Institutional and Development Framework (IAD) in the broader context of New Institutional Economics (NIE) in order to examine the transaction costs of delivering Community and Home Based Care and Support (CHBC) to HIV/AIDS sufferers. For purposes of unveiling the empirical reality guiding decision making processes in the CHBC service delivery, comparative qualitative research techniques of normative variable and concept formation have been adopted to draw out the relative institutional influences from the HIV/AIDS national response partnerships. The study identifies the conflict between the predominantly standardized and more rigid formal management techniques adopted by key members of the national response and the informal cultural techniques familiar to the rural communities, and a lack of motivational incentives in the CHBC structures as the key factors against CHBC capacities to draw external funding for service delivery. CHBCs are also weakened by incoherent governance structures at the district level for facilitation of funding and information flow exacerbating the community vulnerability. Rationalization of the institutional arrangements and a clarification of roles from district to community levels, a shift of focus to facilitation of informal techniques and an integration of performance enhancing incentives are the critical policy insights envisaged to spur CHBCs to work better.

- Description: With the advent of digital networks that link audio devices, there is a need for a protocol that integrates control and connection management, allows for streaming of all media content such as audio and video between devices from different manufacturers, and that provides a common approach to the control of these devices. This paper proposes such a protocol, named XFN, currently being standardized as part of the AES X170 project. XFN is an IP-based peer to peer network protocol, in which any device on the network may send or receive connection management, control, and monitoring messages. Essential to the XFN protocol is the fact that each parameter in a device can be addressed via a hierarchical structure that reflects the natural layout of the device.

This seems to be an appropriate theoretical paradigm within multilingual South Africa, where intercultural communication is becoming a daily reality for a growing portion of the population. We make use of this theory to introduce and develop experiential understanding of multilingualism at Rhodes University in various departments and, more generally, on campus.

- Description: Since the official opening of ex-model C (previously whites only) schools to learners of all races, cultures and languages, there has been an influx of black learners into these schools. Reasons for this are that many black parents believe the quality of education and resources available at these ex model C schools is better than those available in township schools (De Klerk, 2000). Parents also believe sending their children to English medium schools enables them to compete and be marketable in the global world of work. This dissertation describes a qualitative case study of grade 8 learners who took part in a six week intervention conducted at a school in the Eastern Cape where they learn through an additional language (English). The purpose of the intervention was to equip these learners with skills to enable them to improve their reading and comprehension in this language. Participation in the intervention was voluntarily, based on a selection conducted of learners who wrote a baseline English assessment test. Assessments done during the intervention suggest that isiXhosa home language learners fare academically weaker than their English and Afrikaans counterparts who learn through the medium of English. This correlates with findings done nationally and internationally with regard to South African learners’ literacy levels. This dissertation looks at the affective and cognitive effects of the intervention on its participants. Literature on how additional language learning should be done is examined, as well as the Language in Education policy of South Africa (1997). Findings from the research suggest the importance of establishing a ‘safe’ teaching and learning environment for learning to take place optimally and indicate that interventions to improve English reading can produce positive results. Furthermore the research provides evidence that explicitly teaching reading strategies can improve the participants’ comprehension and overall language competence. While English, as the language of technology and economics is acknowledged, it is argued in this dissertation that due to a lack of information to make informed choices, parents and learners become victims of the ‘straight for English’ phenomenon, and learners are robbed of an opportunity to reach their academic potential. However, if additional language learning takes place under the ideal conditions, learners can be enabled to become academically equipped to deal with the demands of learning through an additional language. What is essential for the afore-mentioned to materialize is that learners need to be equipped with reading and comprehension skills in their home language first, for these skills to be effective in attaining the ‘other’ language. Also, learners need to be aware of the fact that they carry knowledge in their own language that can and should be used to learn (in) the additional language.

- Description: Contact centres are the first point of contact between a company and a customer after the purchase of a product or service. These centres make use of contact centre agents to service customer queries. In the past contact centres hired as many agents as they could in order to service customers, which have led to an increase in personnel costs causing contact centres to become costly to run. Automation techniques were introduced to decrease personnel costs and one such technique is the Interactive Voice Response (IVR). The usability of IVR systems is, however, dismal. Customers would rather speak to a contact centre agent than navigate through the menu structure found in these systems. The menu structure has come under scrutiny because it is difficult to use and navigate, is often not aligned to caller usage patterns, and the menu options are long and vague. This research investigated whether a Natural Language Interface (NLI) could alleviate the problems inherent to IVR. NLIs, however, come with their own disadvantages of which the main ones are ambiguity and the loss of context of a conversation. Two prototypes were implemented, one of which resembled an IVR and the other an NLI (using ALICE concepts). An evaluation of two prototypes confirmed the advantages and disadvantages of these concepts in accordance to theory. A Hybrid prototype was proposed with the aid of two models. The model which proposed an NLI using a rule base was chosen for implementation. The Hybrid prototype was then evaluated against the NLI and IVR prototypes to deduce which prototype was the most effective, efficient and satisfying. The evaluation through the aid of descriptive and inferential statistics showed that the Hybrid prototype was the most usable prototype. The evaluation of the Hybrid prototype confirmed that a Hybrid approach could limit the shortcomings of IVR through the elimination of the menu structure found in these systems, thereby allowing users to state their queries in natural language. The incorporated rule base provided the Hybrid system with long term memory, eliminating one of the main disadvantages of NLIs.

- Description: The failure rate of small business initiatives in South Africa is phenomenal, and much is needed to unravel the causes contributing to such failures. Yet small businesses are playing a vital part in our global economy and in particular in terms of job creation and poverty eradication. There are internal as well as external factors that play a significant role in determining the success of these small businesses. In South Africa much emphasis is placed by national, provincial and local governments on small and medium enterprises (SMEs) to drive wealth creation and black economic empowerment. Therefore, an investigation into the factors contributing to the success and failure of SMEs is of vital importance. The South African government’s poverty eradication strategy, which is driven by the Department of Trade and Industry (DTI), allocated funds for job creation programmes as a method to combat poverty and more importantly, to develop young entrepreneurs. Among the seven departments mandated by DTI was the Department of Social Development. Since the birth of the new democracy, this department has transformed from offering a traditional remedial method of service delivery to an integrated developmental approach. This approach included extensive community work, which includes job creation and economic empowerment through the establishment of small businesses. Given the availability of funding, the inability to spend fiscal budgets as per allocation as well as the charity element of receiving involved, it is important to explore whether factors contributing to the success of these SMEs are any different to the traditional business strategies. In this study, the researcher gave special consideration to the social capital element and its contribution in the context of community support as well as the ability of SMEs to become sustainable business ventures over time. The research study aims to highlight unique factors contributing to the success and failures of SMEs established by the Department of Social Development and in doing so hopes to manifest an improved understanding of the management of these SMEs. In chapter one, the researcher gives a brief description of the activities of the Department of Social Development and its mandate to establish SMEs for job creation. A brief explanation regarding the context of the problem that was investigated is also given. Chapter two provides a detailed theoretical overview of the study, focusing in particular on factors contributing to the success and failure of small businesses. In chapter three, the research design and the various instruments used are discussed. Here, emphasis is placed on procedural issues and ethical considerations. The validity and reliability of the research is strongly motivated. In chapter four the research results are discussed. Chapter five aims to discuss the findings of the research with reference to the theoretical overview outlined in chapter two. Lastly, chapter six makes recommendations to the various stakeholders who may benefit from this research. These recommendations are the most important objectives of the research and should add value with regards to the management of SMEs in future, with special reference to the Department of Social Development in the Eastern Cape.

- Description: The tourism and hospitality industry has made a meaningful contribution to the development of the South African economy. Not only the hotels, but also the demand for self-catering holiday properties such as guest houses and bed-and-breakfast Bed and Breakfast establishments is increasing which could boost the tourist industry. Moreover, the prospect of the self-catering holiday properties in South Africa is extremely positive, particularly when the country is given the opportunity to hold the 2010 FIFA World Cup. Thus, expectations and perceptions are significantly shaped and transformed by the prosperous environment. The self-catering holiday properties should provide the best possible service to international and domestic tourists and ensure that their needs are fully met. The general purpose of this study was to evaluate the service quality of guest houses and Bed and Breakfasts in the Nelson Mandela Bay by comparing guests’ expectations and perceptions. The results of this study could assist the managers of guest house and Bed and Breakfast in improving its service performance to more effectively fulfil the needs of dynamic tourist market. The literature study provided an overview of tourism industry from the management and marketing perspectives, services marketing and a detailed discussion of service quality focusing on the nature of services, determinants of service quality and techniques for measuring service quality. The SERVQUAL model and its derivative, Lodging Quality Index (LQI), were adapted for measuring the guests’ perceived service quality in this research. ii The empirical data was collected by means of a survey, using a self-administered questionnaire distributed to guests who were staying at guest houses or Bed and Breakfasts in the Nelson Mandela Bay identified in terms of convenience sampling. One hundred and five useable questionnaires were received. The empirical findings based on the perception-minus-expectation (P-E) gap analysis showed that the perception mean scores were consistently lower than the expectation mean scores. This implies that guests perceived service quality of guest house and Bed and Breakfast to be relatively low. It is recommended that the managers of guest houses and BBs should: uniform the employees; use every tool to figure out what the guest wants; establish specific working procedures and help employees to understand their job responsibilities and mangers’ expectations; invite suggestions of existing located facilities from guests, and move the inconvenient facilities if possible; employ a communication audit to evaluate the overall quality of the communication system by comparing communication objectives to actual performance; combine useful destination information from different sources and update them on the website frequently; and apply an attracting layout to build positive image.

- Description: The tourism and hospitality industry has made a meaningful contribution to the development of the South African economy. Not only the hotels, but also the demand for self-catering holiday properties such as guest houses and bed-and-breakfast Bed and Breakfast establishments is increasing which could boost the tourist industry. Moreover, the prospect of the self-catering holiday properties in South Africa is extremely positive, particularly when the country is given the opportunity to hold the 2010 FIFA World Cup. Thus, expectations and perceptions are significantly shaped and transformed by the prosperous environment. The self-catering holiday properties should provide the best possible service to international and domestic tourists and ensure that their needs are fully met. The general purpose of this study was to evaluate the service quality of guest houses and Bed and Breakfasts in the Nelson Mandela Bay by comparing guests’ expectations and perceptions. The results of this study could assist the managers of guest house and Bed and Breakfast in improving its service performance to more effectively fulfil the needs of dynamic tourist market.

- Description: The primary motivation for this research was to examine political apathy amongst students at Nelson Mandela Metropolitan University. The secondary motivation was to question whether youth political apathy threatens the consolidation of democracy. More specifically, the purpose of the study was to critically analyze contemporary literature on the politics of young people in post apartheid South Africa, in order to identify its shortcomings and give an in-depth explanation for youth political apathy, and how it impacts democracy. The writer has employed a qualitative method. Four focus groups were arranged by the researcher at Nelson Mandela Metropolitan University. All participants of the study were Nelson Mandela Metropolitan University (NMMU) undergraduate and postgraduate black students aged 21-35. The sample of this study included fifty participants. Thus the researcher has utilized a purposive sampling technique. Participants were encouraged by the researcher to have maximum participation in the focus group deliberations. The researcher also made use of elite interviews in the study. The findings of this study suggest that political apathy amongst students at Nelson Mandela Metropolitan University does exist. Most of the participants in the focus groups indicated that young people in post-apartheid South Africa have no interest in politics.

- Description: It has been estimated that between 3000 and 4000 plant species are used for their medicinal properties throughout South Africa, with approximately 27 million South Africans making use of traditional medicines. Of this 27 million, 3 million South Africans rely on traditional medicine as their primary source of health care. Of the 250 000 to 500 000 known plant species, very few have been investigated for their pharmacological qualities, and compounds of significant medicinal value may still remain undiscovered in many plant species. The aims of this study included investigating the antimicrobial properties of Geranium incanum and Artemisia afra, both plants traditionally used for their medicinal properties, and comparing the antimicrobial activity of the latter to that of Artemisia absinthium, as well as investigating the anticancer properties of G. incanum and A. afra, and comparing the anticancer activity of the latter to that of A. absinthium. Infusions, aqueous-, methanol- and acetone extracts of the three plants were prepared and used for anticancer and antimicrobial screening. Plant specimens used to prepare extracts for antimicrobial activity were collected and extracted over three seasons, while extracts used for anticancer screening were prepared from plants collected during the summer only. Considerable variation existed in the percentage crude extract yields obtained when different extractants were used, while the season in which the plants were harvested and extracted also appeared to play a significant role in the amount of extract obtained. The plant extracts were screened for antimicrobial activity against various strains of Candida albicans, Escherichia coli, Pseudomonas aeruginosa, Enterococcus faecalis, Staphylococcus aureus and Bacillus cereus, using an agar dilution method. G. incanum and A. afra possessed activity for C. albicans, while all three plants showed activity for S. aureus and B. cereus. Activity was largely dependent on the extraction method used. iii The 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl tetrazolium bromide (MTT) assay was used to screen for anticancer activity of the respective extracts, at varying concentrations, against MCF-7 (human breast adenocarcinoma) cells, HT-29 (human colonic adenocarcinoma) cells and HeLa (human cervical cancer) cells. All of the extracts showed cytotoxic activity in all three cell lines to varying extents, depending on the extract used and cell line screened. The acetone extract of A. afra proved to be the most effective inhibitor with the lowest IC50 (2.65 ± 1.05 μg/ml) having been shown in MCF-7 cells. A. afra and A. absinthium showed similar inhibitory patterns, with the methanol- and acetone extracts having been the most potent inhibitors of each of the respective cell lines in general. Fluorescence microscopy employing 4',6-diamidino-2-phenylindole dihydrochloride (DAPI) and propidium iodide (PI) staining indicated that the acetone extract of A. afra induces apoptosis in MCF-7 cells as apposed to necrosis, and the results were comparable to those obtained for cells exposed to cisplatin. Screening of the A. afra acetone extract for toxicity in normal human cells using the CellTiter-Blue® assay indicated the extract to be toxic to peripheral blood mononuclear cells (PBMC’s) at concentrations comparable to that for MCF-7 cells, while cell cycle analysis of MCF-7 cells exposed to the A. afra acetone extract indicated the extract’s ability to induce apoptosis comparable to that of cisplatin, with the extract exerting its activity at a point during or just prior to the S phase of the cell cycle.

- Description: Simulation is a complex task with many research applications - chiey as a research tool, to test and evaluate hypothetical scenarios. Though many simulations execute similar operations and utilise similar data, there are few simulation frameworks or toolkits that allow researchers to rapidly develop their concepts. Those that are available to researchers are limited in scope, or use old technology that is no longer useful to modern researchers. As a result of this, many researchers build their own simulations without a framework, wasting time and resources on a system that could already cater for the majority of their simulation's requirements. In this work, a system is proposed for the creation of a scalable, dynamic-resolution network simulation framework that provides scalable scope for researchers, using modern technologies and languages. This framework should allow researchers to rapidly develop a broad range of semantically-rich simulations, without the necessity of superor grid-computers or clusters. Design and implementation are discussed and alternative network simulations are compared to the proposed framework. A series of simulations, focusing on malware, is run on an implementation of this framework, and the results are compared to expectations for the outcomes of those simulations. In conclusion, a critical review of the simulator is made, considering any extensions or shortcomings that need to be addressed.

- Description: This study looks at aspects of the development of environmental education in South African National Parks (SANParks), in relation to the emergence of national and organisational policy frameworks. In order to put current environmental education practices into context, the study firstly looks at the historical development line of environmental education in SANParks, as well as in the broader national context. This provides a framework within which the processes of change and development can be traced in terms of social, political and economic influences on an international and national front. The study finds that the promulgation of legislation, including the Constitution, National Acts and various other policies, reflected the trends of thinking and set the pace in a democratic South Africa, which led to the emergence of more explicit processes and refined policies. Popkewitz’s finding, that education emerged in modernity, is used in the study to illustrate this tendency. It finds that these changes in South Africa resulted in the establishment of more structured environmental education processes within SANParks, and led to the expansion, diversification and strengthening of environmental education as a field of practice over time. The study traces significant processes of recontextualisation of international and national environmental education related policies according to the framework established by Bernstein (1980). These processes of recontextualisation were followed in the formulation processes of SANParks policy and strategy documents in the period from 1999 to 2005, and resulted in an official pedagogic discourse for environmental education in SANParks. The study establishes a second level of recontextualisation, that is, the official pedagogic discourse of environmental education in SANParks is recontextualised to a pedagogic discourse of reproduction. The pedagogic discourse of reproduction relates to park practices, where contextualisation within park-based programmes appears to be strong. The park-based programmes resemble a ‘curriculum in practice’, which brings us to Cornbleth’s critical curriculum approach. The study utilises this approach to explore and explain the meaning of the critical perspective taken on curriculum construction and change efforts at park implementation level (Cornbleth, 1990). The study finds that the contextualisation of park programmes and practices lead to variety in park programmes, which adds richness to environmental education programmes and activities, and further highlights the fact that environmental education practices are prolific in national parks. The study also finds that historical and contextual processes associated with specific parks strongly characterise environmental education programmes and practices in those parks, and that partnership programmes, such as the Kids in Parks programme, contribute towards, and enhance the growth of environmental education as a specialised field of practice in SANParks. The study comments on the need for environmental education practices in SANParks to be reviewed and expanded in line with the contemporary approach towards the environment as a social construct of interacting components. These components include the biophysical, social, economic and political dimensions. The study also highlights the need for the recognition and acknowledgement of the long, historical development line of environmental education in SANParks in order to build on established structures in a holistic way. The study further determines a need for strong leadership to successfully expand this specialised field of practice and encourages a participatory approach in the review and further development of this field of practice in SANParks. The study ultimately finds that environmental education in SANParks has a long and rich development profile, which has placed it in a strong position for further development. However, it concludes that there is a great need for a rejuvenated approach, which requires expert knowledge, professionalism and broad based networking approach to enable meaningful expansion within this specialised field of practice.
