- Description: We investigate the extent to which functional structure and spatial variability of intertidal communities coincide with major biogeographical boundaries, areas where extensive compositional changes in the biota are observed over a limited geographic extension. We then investigate whether spatial variation in the biomass of functional groups, over geographic (10′s km) and local (10′s m) scales, could be associated to species diversity within and among these groups. Functional community structure expressed as abundance (density, cover and biomass) and composition of major functional groups was quantified through field surveys at 20 rocky intertidal shores spanning six degrees of latitude along the southwest Atlantic coast of Argentina and extending across the boundaries between the Argentinean and Magellanic Provinces. Patterns of abundance of individual functional groups were not uniformly matched with biogeographical regions. Only ephemeral algae showed an abrupt geographical discontinuity coincident with changes in biogeographic boundaries, and this was limited to the mid intertidal zone. We identified 3–4 main ‘groups’ of sites in terms of the total and relative abundance of the major functional groups, but these did not coincide with biogeographical boundaries, nor did they follow latitudinal arrangement. Thus, processes that determine the functional structure of these intertidal communities are insensitive to biogeographical boundaries. Over both geographical and local spatial scales, and for most functional groups and tidal levels, increases in species richness within the functional group was significantly associated to increased total biomass and reduced spatial variability of the group. These results suggest that species belonging to the same functional group are sufficiently uncorrelated over space (i.e. metres and site-to-site ) to stabilize patterns of biomass variability and, in this manner, provide a buffer, or “insurance”, against spatial variability in environmental conditions.

- Description: Infectious diseases such as pneumonia still pose a major global health concern. Currently, the world is facing widespread emergence of acquired bacterial resistance to antibiotics which constitute one of the chief causes of infectious diseases. The accumulation of different antibiotic resistance mechanisms within the same strains has induced the appearance of the so called “superbugs”, or “multiple-drug resistant bacteria”. Due to antibiotic resistance, attention is currently being drawn towards biologically active components isolated from plant species commonly used as herbal medicine, as they may offer a new source of antibacterial, antifungal and antiviral activities. This is the basis of this study. In this study four medicinal plants namely, Cassia abbreviata, Geranium incanum, Pelargonium hortorum and Tecoma capensis were investigated for their antimicrobial potential. In vitro antimicrobial activity using agar disc diffusion method, agar dilution method and broth microdilution plate determination of minimum inhibitory concentration (MIC), were carried out against ATCC (American Type Culture Collection) strains and clinical isolates known to cause pneumonia. Aqueous, methanol and acetone extracts from the selected plants were thus tested against strains of Streptococcus pneumoniae, Haemophilus influenzae, Staphylococcus aureus, Klebsiella pneumoniae, Pseudomonas aeruginosa, Acinetobacter baumannii, Escherichia coli and Candida albicans. The plants exhibited pronounced antimicrobial activity and were more active against Gram-positive bacteria than Gram-negative bacteria. During agar disc diffusion method, the highest inhibition zone was demonstrated by the acetone extract of P. hortorum (IZ=22mm and AI=0.73) against the reference strain of S. pneumoniae (ATCC 49619). The range of zones of inhibition in diameter across strains of S. pneumoniae and H. influenzae was 7mm to 22mm with activity index range of 0.23 to 0.74. The lowest MIC produced by medicinal plants in the study during agar disc diffusion method against S. pneumoniae and H. influenzae strains, was 2.5mg/ml. In broth microdilution plate assay, the lowest MIC demonstrated by C. abbreviata, T. capensis and P. hortorum extracts on tested bacteria was 0.031mg/ml and that of G. incanum was 0.063mg/ml. Candida albicans strains were only inhibited at 20mg/ml by the study plants. The highest activity among the individual extracts was shown by P. hortorum methanol extract which inhibited 71% of the studied bacteria. T. capensis methanol extract was the least and inhibited only 17% of the tested bacteria. The strains of Klebsiella pneumoniae showed the highest resistance to medicinal plants employed in this study. Traditional preparation of selected medicinal plants did not show any significant antimicrobial activity. Bioactive analysis of compounds on study plants was carried out using standard methods which revealed the presence of anthraquinones, flavonoids, phytosterol, saponins, tannins and triterpenoids. Comparison of the inhibitory effect of the plant extracts against some broad spectrum antibiotics revealed that the tested medicinal plants showed greater antimicrobial activity than standard antibiotics. However, there was no correlation between the antibiotic susceptibility patterns of the bacteria and the effects of the plants, signifying that plants probably function through different mechanisms. Bioautographic findings on thin-layer chromatography plate, exhibited clear zones of inhibition of bacterial growth with the Rf value range of 0.09 to 0.94. Anti-mutagenic activity was assayed by the Ames mutagenicity test in the plate-incorporation method using histidine mutants of S. typhimurium strains TA 100. The selected plant extracts at 2.5mg/ml and 5mg/ml did not induce mutagenesis in the absence of liver-metabolizing enzymes. The study results indicated that the selected plants are capable of inhibiting the growth of the studied pathogenic microorganisms to a varied degree. The leaves of G. incanum, P. hortorum, T. capensis as well as the stem bark of C. abbreviata could be novel sources of antimicrobial agents that might have broad spectrum activity. The anti-mutagenic properties of the studied medicinal plants may also provide additional health supplemental value to the other claimed therapeutic properties of the plants.

- Description: Globally largemouth bass Micropterus salmoides is one of the most widely introduced game fish species which has now become invasive in many countries. Well researched in its native North America, there are few studies on this species in its introduced range. This study aims to improve the understanding of the biology and ecology of M. salmoides in temperate southern Africa, where it threatens native biota and supports a popular recreational fishery. This aim was addressed by assessing the age, growth, maturity, reproductive seasonality, feeding, mortality and movement, of two M. salmoides populations from Wriggleswade (1000 ha, 723 m amsl, 32º35'S; 27º33'E) and Mankazana (35 ha, 66 m amsl, 33º09'S; 26º57'E) Dams in the Eastern Cape of South Africa. The most suitable structure for ageing M. salmoides was determined by comparing the accuracy and precision of otoliths and scales. Scales tended to underestimate the age of fish older than five years. Sectioned sagittal otoliths were the more precise structures for ageing (otoliths CV = 15.8 vs. scales CV = 21.9). The periodicity of growth zone formation was validated as annual for otoliths using both edge analysis (EA), and mark recapture of chemically tagged fish (MRCT). EA indicated one annual peak in the frequency of opaque margins between September and January using a periodic logistic regression and a binomial model linked with a von Mises distribution for circular data. MRCT showed the linear relationship between time at liberty and number of growth zones distal to the fluorescent band was not significantly different from one (slope = 0.89). Reproduction was similar to that in native and non-native populations with fish reaching age at 50% maturity at ca. two years, and length at 50% maturity at 259-290 mm FL depending on growth rate. Spawning season occurred in the spring months of August to October. The Wriggleswade Dam population reached similar ages (14 yrs) to populations in temperate North America. Growth was described using the von Bertalanffy growth equations of (Lt = 420(1-ᵉ⁻°·³³⁽ᵗ⁺°·²¹⁾) mm FL in Wriggleswade and (Lt = 641(1-ᵉ⁻°·²²⁽ᵗ⁺°·⁷⁶⁾) mm FL in Mankazana. Growth performance of both populations, described using the phi prime index, seemed to be correlated with temperature and the Wriggleswade Dam population (Φ’ = 2.8) grew similarly to those native temperate North American populations and the non-native populations of Japan and Italy. The Mankazana population had a higher growth performance (Φ’ = 2.9) compared to Wriggleswade and growth was comparable to other nonnative African populations. Both populations utilised all available food resources, with the Mankazana population being in better condition than the Wriggleswade population as a result of a more diverse diet, highly abundant food sources throughout the year, and potentially the adoption of a more conservative ambush feeding strategy. The Wriggleswade population, which was utilised by competitive anglers, showed low mortality rates (Z = 0.43 yr⁻¹), and translocated fish dispersed from the common release site, travelling an average distance of 4km over the study time of 494 days. These results indicated that M. salmoides are successful in these environments, growing at expected temperature dependant rates, maturing at two years, using all available food groups, and suffering from low mortality. It is therefore likely that they will persist in South Africa and establish where introduced.

- Description: The aim of this study was to explore and describe the body fatness and associated selected health risk factors among 10 to 12 year old adolescents attending schools in Port Elizabeth. Therefore the objectives of the study were to determine the following for the participants: • Level of fatness: weight, height, waist circumference, maximum hip circumference and skinfolds; • Fat intake; • Level of physical activity involvement (IPAQ). To achieve the aim and objectives of this study, the literature pertaining to Childhood Obesity and the possible effects thereof, were reviewed. Both an ex post facto quasi experimental and randomized one-group posttest only designs were used to describe the level of fatness and to identify the incidence of overweight and obesity among adolescents aged 10 to 12 years attending schools in Port Elizabeth. The test battery included anthropometric measurements that were identified from the literature as the factors most important to categorise body fatness such as weight, height, circumferences and skinfolds to determine the level of fatness of the participants. A 21-item Fat Measure for Dietary Intake and International Physical Activity Questionnaire were administered to determine the levels of fat intake and physical activity. Three hundred (300) adolescents were assessed of which 143 were male and 157 were female. In terms of socioeconomic status, 71.3 percent were from the ‘less poor’ quintile schools and 28.7 percent were from the ‘more poor’ quintile schools. The results obtained from the evaluation of the samples were compared in terms of their descriptive statistics and the differences were tested for statistical and practical significance. The results from the study showed that 26.7 percent of the participants were overweight and 14.7 percent were obese according to their skinfold measurements. In terms of body mass index, 79.7 percent of the participants were overweight and 14.3 percent were obese. These results are far higher than majority of the studies included. Physical activity indicated a reduction in body fatness and the most physically active participants were obese. Lastly, body fat percentage and body mass index are very closely related.

- Description: This treatise explores the Matatiele boundary demarcation dispute and, in particular, the role that unmet basic human needs play in this dispute. The subject of identity is also explored. In 2006, the government of South Africa decided that Matatiele should no longer be part of the province of Kwa-Zulu Natal (KZN) and instead should be incorporated into the province of the Eastern Cape. This decision divided the community of Matatiele into two groups; one was pro-KZN and the other, pro-Eastern Cape. In 2008, violence broke out between these two groups. The government’s decision and the resulting violence have created a situation of protracted conflict in the community of Matatiele with rivalries and antagonism being part of the fabric of the society. This treatise attempts to analyse this conflict and link it to the theory of basic human needs as advocated by conflict theorists such as John Burton and Johan Gultang. Human needs theorists hold the view that unmet psychological and physical needs are sources of social conflict and can lead to protracted conflict. This treatise also explores the efficacy of problem-solving workshops and referendums as conflict-resolution techniques for boundary demarcation disputes. The data were collected from unstructured, in-depth interviews with a sample of eleven respondents. The data indicate that there is a nexus between this conflict and the theory of basic human needs and that community-identity concerns are central to this dispute. The findings of this study suggest that the conflict is multi-faceted and that the underlying causes can be attributed to unmet human needs. The data was analysed using the grounded theory approach. This allowed the key causes of the conflict to be identified and subsequently informed the recommendations presented in the conclusion of this treatise.

In 2006, the government of South Africa decided that Matatiele should no longer be part of the province of Kwa-Zulu Natal (KZN) and instead should be incorporated into the province of the Eastern Cape. This decision divided the community of Matatiele into two groups; one was pro-KZN and the other, pro-Eastern Cape. In 2008, violence broke out between these two groups. The government’s decision and the resulting violence have created a situation of protracted conflict in the community of Matatiele with rivalries and antagonism being part of the fabric of the society. This treatise attempts to analyse this conflict and link it to the theory of basic human needs as advocated by conflict theorists such as John Burton and Johan Gultang. Human needs theorists hold the view that unmet psychological and physical needs are sources of social conflict and can lead to protracted conflict. This treatise also explores the efficacy of problem-solving workshops and referendums as conflict-resolution techniques for boundary demarcation disputes. The data were collected from unstructured, in-depth interviews with a sample of eleven respondents. The data indicate that there is a nexus between this conflict and the theory of basic human needs and that community-identity concerns are central to this dispute. The findings of this study suggest that the conflict is multi-faceted and that the underlying causes can be attributed to unmet human needs. The data was analysed using the grounded theory approach. This allowed the key causes of the conflict to be identified and subsequently informed the recommendations presented in the conclusion of this treatise.

- Description: The treatise analyses the issues around budgets and examines budget expenditure control procedures. The research method selected has been formulated from the research onion process (Saunders, Lewis and Thornhill 2009). This methodology first identifies the research approach, research strategy, timelines and data collection methods. As part of the research process, a quantitative approach has been taken and a survey was carried out in relation to the collection of quantitative data for the purposes of the treatise research. The final analysis of the survey results is reflected in the conclusion of the research findings. Budget expenditure control procedures provide a company with a method of control for managing actual spending against the budget. Most companies have a refined practice of budget preparation, and in the larger companies, these are implemented across all departments and carried out by respective managers. Once the budget is in place, it is the responsibility of the managers to ensure that those having expenditure authorisation adhere to it. If control procedures are well managed, this allows for improved efficiency in operations and can lead to benefits in budget performance. Control procedures that are inefficient and poorly managed will inhibit budget objectives being achieved. The control procedures for budget expenditure can be formulated and applied to optimise budget performance and to control budget variance. Formal budget expenditure control procedures, as part of a company’s budget strategy, can provide managers with an effective business tool that improves current budget spending control procedures. This will then result in the identification of potential efficiency gains and improve budget performance.

- Description: Business incubation is a concept that describes a business development process that is used to grow successful, sustainable entrepreneurial ventures that will contribute to the health and wealth of local, regional and national economies. Incubators provide a place for businesses to build their foundations. Business incubators use a combination of physical space, resources and services to facilitate and develop businesses, enhance their progress, break down barriers to success, reduce risks and increase the potential for successful survival of early stage ventures., their progress, break down barriers to success, reduce risks and increase the potential for successful survival of early stage ventures. Business incubators are part of a larger value chain that connects enterprises to a vital support system. Most incubators connect their clients to local service providers (such as lawyers, corporate service providers or accountants) and establish relationships that will last after the firm leaves the incubator. Once an enterprise is ready to leave the incubator environment, it will need space to move into, which in turn, boosts property development and leasing. Because of the enhanced credibility of the business incubation process, landlords would be more confident as a stable, growing business can be a reliable tenant. The empirical object of the study is the Seda NMB ICT Incubator in Port Elizabeth. Eastern Cape. Like any other business an incubator is created to deliver a service or product for as long as possible and in this process must create value because the ultimate objective of any profit seeking business is to create wealth for its owners with due consideration of all its stakeholders (Brigham & Ehrhardt 2005:7-12). A preliminary investigation of the Seda NMB ICT Incubator raised the question whether the operation of this incubator meets the performance standards as identified in the international literature. The purpose of this study is therefore to establish whether the performance of the Seda NMB ICT Incubator is in line with generally accepted performance standards. At this stage the standards can be identified as a strategic alliance of the business (vision, mission and strategy), financing principles, management principles and human resource development and growth opportunities. The SEDA NMB ICT Incubator is financed as follows: Partly by the Department of Trade and Industry (the SEDA technology programme) and partly by the Nelson Mandela Bay Metropolitan Municipality. It is recommended that public/private partnerships should be formed to ensure the continuity of the Port Elizabeth incubator. A second recommendation is that the SEDA NMB Incubator becomes more focussed in terms of its clients it is serving. At present it is serving a wide variety of ICT clients ranging from website design, graphic art to preparing business plans for ICT businesses. The period of incubation may be too extended as some incubatees have been on the premises for more than five years. It is recommended that the SEDA NMB Incubator pays attention to the length of stay of an incubatee. The vast majority of the incubatees on the SEDA NMB Incubator premises are not compliant with business acts and regulations. Seven incubatees reported during the personal interview that they were not compliant with all the acts and regulations.

- Description: Literature emphasizes how important it is that procedural and conceptual knowledge of mathematics should be learned in integration. Yet, generally, the learning and teaching in mathematics classrooms relies heavily on isolated procedures. This study aims to improve teaching and learning of partitive and quotitive division, moving away from isolated procedural knowledge to that of procedures with their underlying concepts through the use of manipulatives, visual representation and questioning. Learning and teaching lessons were designed to teach partitive and quotitive division both procedurally and conceptually. The study explored the roles these manipulatives, visual representations and questioning played toward the conceptual learning of partitive and quotitive division. It was found that manipulatives and iconic visualization enhanced learning, and this could be achieved through scaffolding using a questioning approach. It was concluded that manipulatives and iconic visualization need to be properly planned and used, and integrated with questioning to achieve success in the learning of procedural and conceptual knowledge.

- Description: In this study the main focus is on the experiences of former street children as learners. The main emphasis of this study is the manner in which such experiences influence these children’s learning towards constructing new identities. By examining the experiences of former street children in a school environment, namely a teaching and learning environment, this study will contribute towards the literature by providing focused and relevant information pertaining to the way former street children experience learning. By focusing on these particular learners from the street, the study attempts to explore and build an insightful knowledge in terms of understanding how former street children perceive learning in relation to their present personal and past life on the streets. Through this study the researcher will hopefully be able to determine how former street children feel, experience and relate to teaching and learning within a school context. Data collection for this study included the researcher’s observations and face-to-face unstructured in-depth phenomenological interviews with learners who are formerly from the streets. Among others, the study found that these particular learners have low self- esteem, a low opinion of themselves, and lack of self- confidence. The study also revealed that some of these learners are struggling academically and would appreciate it if academic was parallel with vocational skills so as to equip them for the world of work. It also transpired that learners who have relationships with those who have not been to the streets changed their lives for the better by learning from their peers but those who have relationships with other former street children at this school continue to engage in deviant behaviour, for many schooling has helped them to reclaim their childhood identity.

- Description: Polybenzimidazole fibers, with an average diameter of 262 nm, were produced by the process of electrospinning. These fibers were used as a solid support material for the immobilization of oxovanadium(IV) which was achieved via a reaction with vanadyl sulfate. The oxovanadium(IV)-functionalized nanofibers were used as heterogeneous catalysts for the oxidation of thioanisole under both batch and pseudo-continuous flow conditions with great success. Under batch conditions near quantitative oxidation of thioanisole was achieved in under 90 min, even after four successive catalytic reactions. Under continuous conditions, excellent conversion of thioanisole was maintained throughout the period studied at flow rates of up to 2 mLh−1. This study, therefore, proposes that electrospun polybenzimidazole nanofibers, with their small diameters, impressive chemical and thermal stability, as well as coordinating benzimidazole group, may be a desirable support material for immobilization of homogeneous catalysts.

- Description: [from introduction] Darwin (1871) proposed the mechanism of sexual selection to explain the extreme traits, secondary sex characters, seen primarily in male animals for either display or competition. These elaborate traits for attracting members of the opposite sex or competing for access to mates, inter- and intra-sexual selection, respectively, would increase the mating success of individuals but may reduce individual survival. Sexual selection has traditionally been associated with motile, dioecious animals that have well-developed sensory abilities and has long been viewed as absent as a mode of selection in plants (Grant, 1995). However, since the 1980s, several workers have argued that sexual selection is applicable to plants and should be considered as a factor in floral evolution (Skogsmyr & Lankinen, 2002). Opponents such as Grant (1995) point to incompatibility with Darwin’s usage, hermaphroditism, the absence of obvious secondary sex characters and the apparent absence of female choice in plants (Skogsmyr & Lankinen, 2002; Moore & Pannell, 2011). Proponents, however, argue that historical definitions should be expanded to explain modern evidence and that sexual selection can, in principle, occur in hermaphrodites and hence play a role in the evolution of floral traits. The latter view is supported by a recent study by Cocucci et al. (this issue of New Phytologist, pp. 280–286) which demonstrates intra-sexual selection in plants via direct male–male competition between the pollinaria of milkweeds for optimal attachment sites on pollinators to ensure subsequent pollinium deposition. This is the first example of male–male competition resulting in secondary sex characters in hermaphrodite plants, highlighting the possibility of overlooked mechanisms of sexual selection in plants.

- Description: This study investigated challenges encountered by schools in the implementation of inclusive education in the Eastern Cape. It was a Survey Study carried out in Ngcobo District. School principals of randomly-sampled mainstream schools and special schools participated in this research project. The key research question that the study sought to answer was: What are the challenges encountered by schools in the implementation of Inclusive Education in the Ngcobo District of the Eastern Cape Province? The following were the sub-research questions: (a). How does the lack of specialized or in-service, trained human resource personnel challenge or hinder the implementation of Inclusive Education? (b). How is the implementation of Inclusive Education affected by available infra-structure? (c). How do the attitudes of stake holders such as learners, educators (ILST) and parents (SGB) affect the implementation of inclusive education? The findings of the study revealed that: There is a gross shortage of educators qualified in inclusive education or related streams, and in some schools none at all. Institution Level Support Teams (ILSTs) in some schools have not been established and some of those that are established are not functional. Needed specialists such as psychologists and occupational therapists are not available in special schools. Workshops or in-service training for educators generally are held for to ILSTs only instead of all educators and SMTs. School buildings and toilets have not been adapted for when inclusion is to be implemented and there are no specific, funded departmental projects to rectify this. Assistive devices for learners experiencing barriers to teaching, learning and development are rarely found. There are no clear departmental budgets to ensure the policy is implemented in ordinary schools. Negative attitudes of some parents, teachers and learners toward inclusion still exist. The following recommendations were made for consideration in order to facilitate the smooth implementation of Inclusive Education in the schools. There should be adequate provision of human resource training and development Educators have to further their studies in Inclusive Education. There should be provision of a specific budget for buildings. Maintenance funds ought to be used to renovate school buildings so as to be Inclusive Education friendly. Advocacy and awareness programmes for different stakeholders should be conducted.

The following recommendations were made for consideration in order to facilitate the smooth implementation of Inclusive Education in the schools. There should be adequate provision of human resource training and development Educators have to further their studies in Inclusive Education. There should be provision of a specific budget for buildings. Maintenance funds ought to be used to renovate school buildings so as to be Inclusive Education friendly. Advocacy and awareness programmes for different stakeholders should be conducted.

- Description: This Research was undertaken to explore the challenges faced by the Eastern Cape Department of Local Government and Traditional Affairs Integrated Development Planning Unit to support municipalities to deliver credible Integrated Development Plans (IDPs), using Sunday’s River Valley Municipality as a case study. The legal obligation of the Department of Local Government is to support Municipalities to able them to perform their function and execute the duties allocated to them. This mandate originates from the Constitution of the Republic of South Africa, Act 108 of 1996. The Provincial Department of Local Government Integrated Development Unit is therefore obliged to support and guide municipalities in the development of IDPs by mobilizing and coordinating sector departments to participate in IDP processes, and to identify and allocate funds for projects. It is suggested that the DLGTA IDP Unit is not doing enough to support municipalities so as to deliver credible IDPs, hence the wide-spread violent service delivery protests. The study aimed at establishing whether there is a direct link between the efforts or not of DLGTA to help the municipality to develop a credible IDP and service delivery protests. The IDP may be credible, but the implementation may be flawed, or funding does not flow as expected, or the people on the ground may not understand that it may take years to deliver services. The study targeted senior managers of coordinating Departments, the Sunday’s River Valley Municipality (SRVM) and IDP Managers of SRVM and the Cacadu District Municipality (CDM). The study discovered that sector departments do not participate meaningfully in IDP processes mainly because: (1) SRVM does not extend invitations to all sector departments to attend IDP meetings; (2) There is no legal obligation to participate at local level; (3) There appears to be no commitment shown by senior managers of SRVM on IDP Processes. The DLGTA IDP Unit efforts to assist SRVM to deliver credible IDPs cannot be deemed successful, because the SRVM IDP continued to receive medium rating score for four years in succession. The DLGTA IDP Unit never paid attention to the issues cited above as the cause of stagnation of SRVM IDP. The DLGTA IDP Unit was not aware that the issues cited above were the cause for the poor SRVM IDP until the researcher brought it to their attention. It is therefore recommended that the culture of participation in the IDP processes by top management of both SRVM and DLGTA should be included in the performance contracts of top management officials. It is also recommended that the Inter Governmental Relations (IGR) Framework Act be reviewed to recognize IGR IDP Structures at local level such as IDP Representative Forums. The Act currently is silent on those structures at local level.

- Description: Tourism is gradually recognized and acknowledged as an important sector to drive economic growth across many nations. It is by no coincidence that the South African government took a bold decision to elevate the importance of tourism in the economy through the establishment of a dedicated tourism ministry in 2009. Tourism derives its mandate from the Constitution of the Republic of South Africa 108 of 1996, which outlines tourism function as an area of concurrent competence between the three spheres of government that is national, provincial and local government. According to Tsatsire (2008:1), the new mandate given to local government post 1994 implies that local government is no longer expected to render basic services only, but is also required to serve as an agent of development. The main objective of the study is to identify the challenges faced by the municipalities in the implementation of tourism functions, using UMgungundlovu District Municipality as a case study and pursued the following specific objectives: To establish the roles and responsibilities of municipalities in tourism; To assess whether these responsibilities are adequately performed and to understand the reasons for deficiencies, if there are any; To highlight the contribution of tourism to local economic development; To ascertain the status of the implementation of the tourism strategy for the UMgungundlovu District Municipality (UMDM); To highlight the significance of the role of municipalities in achieving national and provincial tourism objectives and; To recommend appropriate actions to overcome the challenges pertaining to implementation of tourism at a local government level. The study is premised upon the acknowledgement that there are many developmental challenges facing municipalities and tourism is one of them. With tourism being recognised more and more as an essential component of local economic development, municipalities are required to play a central role in ensuring the implementation of national and provincial priorities to boost the sector’s contribution to the economy. The study explores various pieces of legislation upon which tourism mandate on local government is embedded. This has enabled to provide clarification with regards to the roles and responsibilities of local government in tourism. The connection between tourism and local economic development is succinctly discussed to ascertain the benefits of tourism and its contribution in local economy. The study took a form of qualitative research and therefore employing the use of qualitative research techniques in terms of data collection, analysis and interpretation process. Data were collected through the review and analysis of strategy documents including the Local Economic Development Strategy, Tourism Strategy and the Integrated Development Plan of UMgungundlovu District Municipality. Interviews were also conducted with the officials responsible for tourism within UMDM and other local tourism stakeholder organization within the study area including uMsunduzi Pietermaritzburg Tourism Association, Howick uMngeni Community Tourism Association, Pietermaritzburg Business Chamber of Commerce, KwaZulu Natal Department of Economic Development and Tourism and Tourism KwaZulu Natal. The methodology that was followed in the study has enabled the researcher to address all the study objectives and to compile the findings report presented in chapter four. Tourism is one of the functions of local government; however, municipalities are faced with a variety of challenges in the implementation of tourism function. Challenges that are pertinent to UMDM are discussed and articulated in this report. The study concludes by documenting the recommendations conferred by the respondents with the objective to overcome the challenges pertaining to implementation of tourism at a local government level. These recommendations are further discussed to explore practical actions on how the UMDM can overcome the identified challenges to enhance local economic development through tourism.

- Description: The main focus of this study is the challenges of rural tourism development in Zimbabwe. The study identified that there is a lack of sustainable interventions in the development of rural tourism which is catalyzed by the absence of rural tourism promotion strategy to support the sustenance of livelihoods through socio-economic transformation. Meaningful socio economic transformation in the African rural areas through tourism remains a major development challenge. Development initiatives through different forms of tourism in the rural communities, has to a less magnitude benefited the rural communities and have negatively impacted the socio–economic environment. A qualitative research methodology and case study design was employed in order to have a deeper understanding of the experiences of the society around this project. Face to face interviews and focus group discussions guides were used to collect primary data. Purposive and convenience sampling techniques was employed to select respondents. Data was analysed using the transformative theory and sustainable livelihoods theory and was organized into categories and themes. The study established that the absence of a strategy is caused by political instability, community conflict, lack of finance, marketing, poor communication, and limited knowledge of tourism. All the aforementioned reasons complement each other and poise a challenge to the sustainability of rural tourism development. For Zimbabwe to effectively transform its economy through tourism, the government needs to plan the process, formulate and implement relevant economic and social development strategies and policies. Although this dissertation is a case study of sustainable rural tourism in Zimbabwe, it can be used to appreciate the role of tourism in bringing about socio-economic transformation and sustaining livelihoods in developing countries.

- Description: Technology education is an important factor in every learner’s education. It contributes to the intellectual and practical development of the learners to enable them to cope with the challenges of a technological society. The main purpose of the study was to investigate the extent to which the learning and teaching of technology were implemented in schools in the Mthatha District. The main research question was: What are the challenges for the implementation of technology learning area in the Senior Phase? Research sub questions were: What support does the Department of Education give to educators?; To what extent have the objectives of implementing the technology learning area been achieved?; and, What suggestions do educators have to improve implementation of technology education? There were 20 Junior Secondary Schools involved in the study. There were two groups of samples: (a) the educators’ sample and (b) the learners’ sample. The educators’ sample: The sample size was 20 educators consisting of those who were teaching technology in either all the Senior Phase grades (Grade 7, 8 and 9) or at least in one of the grades in the senior phase in his/her school. On the researcher’s request, the Principal of each school nominated an educator and hence there was one educator in the educators’ sample from each of the 20 schools. The learners’ sample: The sample size was 40 learners consisting of at least two learners from each of the 20 schools. On the researcher’s request each educator in the educators’ sample nominated two learners from the senior phase. The instrument which was made to collect data was a researcher-designed questionnaire. The researcher personally visited each school involved in the study and gave the questionnaires to the two learners and one educator from that particular school to complete them independently within five days. The researcher personally re-visited each school on a day after the agreed-upon 5-day period but only after confirming over the phone that the questionnaires were indeed completed. The data were analyzed manually. The results obtained revealed that the implementation of the technology learning area is challenged by a number of problems. Those which were specifically identified were: lack of resources especially the rural schools; lack of people who are knowledgeable on Outcomes-based education (OBE) or the OBE modes of learning & teaching technology and its assessment methods, ineffectiveness arising out of large and overcrowded classes, challenges originating from or as a consequence of redeployment and the rationalization of educators and the lack of human resource to assist in the implementation of technology. The study showed the need for the provision of supportive service and continuous contact with educators to offer advice and assistance in order to improve the quality of technology teaching and learning in schools. The professional knowledge and skills of subject advisors as well as educators needed to be extended, refreshed and updated.
