- Description: This study aimed to provide South African public relations professionals with insights into the use of the Social Media News Release (SMNR) as a PR 2.0 tool that has the potential to elicit consumer-driven dialogue in social media channels about information, a brand, product or service advocated by the particular social media news release. Drawing on literature from fields such as public relations, new media studies, marketing, and consumer studies, an analysis of two South African SMNR case studies was conducted including the Samsung Omnia i900 SMNR and the Standard Bank Pro20 2008 and 2009 SMNRs. An in-depth content analysis applying limited designations analysis and detailed assertions analysis techniques was performed on selected content from the dedicated social media platforms linked to in the SMNRs to determine the origins, tone and thematic nature of communications on the platforms. A total of 2071 messages was analysed by means of content analysis across six social media platforms in the two case studies. In order to triangulate and support data, an online survey was conducted with 43 social media users as respondents in order to determine social media users’ interactions with the social media platforms and SMNRs. The study found that the social media platforms linked to the SMNRs in the two case studies largely successfully elicited and hosted social media user-generated conversations about the themes advocated by the SMNR. The Blog, Facebook and YouTube platforms proved to be most successful in generating social media conversation, while the Flickr, Twitter and Delicious platforms were less effective among South African consumers. It was found that social media news releases are likely to elicit consumer-driven dialogue on the dedicated social media platforms linked to by the SMNRs if the platforms are managed correctly. Factors that were identified as important management considerations include ensuring the relevancy and timeliness of content on the social media platforms, the involvement by the platform creator in stimulating and encouraging participation from social media users where necessary, as well as the swift response to user comments, deleting of spam comments and pro-active management of negative perceptions that may arise from user comments on the platforms.

- Description: Mining companies operating in developing countries like the Democratic Republic of Congo (DRC) have come under increasing public criticism for not only failing to bring benefits to the country in which they operate but for often making the situation even worse through adverse environmental and social impacts. The particular focus of this treatise is the social division that a new mining project can generate between the operating company and the community living on or near to the mine site. In one area in north-eastern DRC, a large multinational mining company, AngloGold Ashanti, plans to develop a gold mine. While there have been no manifest conflicts between the company and the host community, there is evident latent conflict in the form of uncertainty and mistrust between parties. Although the company is engaged in two different models of companycommunity participation, this has either resulted in or failed to prevent tensions between the company and the local community. This research offers an exploration and discussion of the existing models of company-community participation as a conflict management strategy. With reference to relevant research and literature, as well as other available models for company-community participation, this treatise will provide a series of recommendations as to how the existing models could be made more effective in managing conflict.

- Description: A qualitative empirical phenomenological study was undertaken to determine the self-experience of procrastinating behaviour. Five students each gave an account of an occasion when they procrastinated. The resultant protocols were analysed and the Situated Structure of each individual’s experience was reported. From these, the General Structure of procrastinating behaviour was determined. A further, novel step was added to the standard methodology, whereby ‘themes’ were extracted from participant protocols and a ‘Composite Reality’ of everyday-life procrastination was rendered. Participants’ accounts suggest they are concerned the results of intellectual tasks they undertake will be seen as equivalent to their quality of being-as-an-individual: poor work results will be interpreted by important-others as evidence of participants’ poor quality of self – which is to be avoided. This study suggests that procrastination is a ploy used by individuals to avoid criticism, by deflecting assessment of their capacity to complete a task well, to instead, what they are capable of when only a limited time is available. Conclusions drawn by the important-others of participants’ true ability are thereby confounded. The results achieved in the phenomenological study were compared with others originating from various quantitative studies, and considerable overlap was found. The experiential richness of the phenomenological results point to a worthwhile methodological strategy for future procrastination research.

- Description: The present neutrino oscillation data are compatible with tri-bimaximal mixing, to leading order. The addition of an A₄ family symmetry and extended Higgs sector to the Standard Model can generate this mixing pattern, assuming the correct vacuum expectation value alignment of Higgs scalars. The effect of deviating this alignment is studied, for different types of A₄ models, with a phenomenological emphasis: the effect of perturbations on the model predictions for the neutrino oscillation and neutrino mass observables. The standard theoretical description of neutrino oscillations is presented, along with a summary of the past, present and future experimental efforts aimed at measuring the neutrino mixing parameters. Additionally, the current constraints on the sum of absolute neutrino masses and the amplitude for neutrinoless double beta decay, which is yet to be observed, are discussed. These constraints provide a model-independent test of family symmetery models. The Standard Model is reviewed, and extensions to the Standard Model such as the seesaw mechanism(s) are discussed: these are designed to endow neutrinos with mass, and can be incorporated into A₄ symmetry models. Models with different A₄ particle assignments are analysed for deviations from tribimaximal mixing. There are nine models presented in Chapter 5, with lepton doublets transforming as 3 (underlined) and right-handed charged leptons transforming as 1, 1', 1" (all underlined) ; five of these include right-handed neutrinos transforming as 3 (underlined) and make use of the seesaw mechanism. Chapter 6 contains the analysis of six models that assign all leptons to the 3 (underlined) representation, with four of these utilising the seesaw mechanism. The models are tested for any degree of fine tuning of the parameters that define the mass matrices. The effect of perturbations on the mixing angle observables, in particular sin² ∅₁₃ and sin² ∅₂₃, is studied, as well as the effect on the Jarlskog invariant, Jcp. Investigations of the (Mee)- ∑Mv parameter space allow for comparison with current data, and can lead to the possible exclusion of a particular model by constraints from future data.

- Description: Thermal spraying is a technology, which is used for coating of components and structures in order to achieve certain tribological characteristics, or for protection against corrosion, excessive temperature and wear. Within thermal spray, there are processes, which utilise combustion of liquid fuel to obtain high velocities flows providing, therefore, good adhesion of coating materials to substrates. These include High Velocity Oxygen Flame (HVOF) and High Velocity Air Flame (HVAF) process, of which the former one is widely used as it has been developed for at least two decades, while HVAF is less common. However, some studies indicate that HVAF has a number of advantages over HVOF, including the economic benefits. The thermal spray gun, based on the HVAF process, has been developed before, but the system was controlled manually. Therefore, there is a need to develop a fully automated controller of an HVAF thermal spray system. Process control of thermal spraying is highly complex as it involves simultaneous control of a number of processes, including; ignition process, combustion process, spraying material melting, as well as control and monitoring of auxiliary equipment. This paper presents the development of a control system for an HVAF thermal spray system, based on a Microchip PIC microcontroller. The designed control system was applied for controlling of thermal spraying of carbides powders, and provided a reliable ignition and stable combustion process, powder feeding and all other functions of control.

- Description: In the new dispensation, there are many challenges, especially concerning corruption. In this regard, the Eastern Cape is viewed as the most affected province, with the Department of Education identified as culprit number one engaging in corrupt activities. There are a number of contributing factors, as attributed in the study, but most prevalent among these is the vastness of the department, with fewer personnel and less capacity. Challenges of corruption in the Department of Education are perpetrated mainly by the civil servants. This study, researched the challenges of corruption in the Department of Education in the Eastern Cape, in particular by focusing on both the achievements and the limitations that have been experienced; and indeed, there are still numerous issues to be addressed and accomplished. The research, therefore, has been significant in that it touched on critical issues, such as, the public sector in general, which is corrupt. Misappropriation of public resources and corruption immersed the nation, as a whole, into a greater challenge rather than focusing on service delivery issues. There are situations, within the department, where the majority of senior officials, who may be in possession of valuable information, are always under suspension. In all the financial years the Department of Education existed, it always obtained disclaimer or adverse reports from the Office of Auditor-General (AG), despite numerous attempts and interventions by the AG‟s office and the Provincial Treasury to rectify the situation. There are also serious challenges of leadership crises in the Department of Education, both administratively and politically. During the research, that is, between the 2008 and 2010 financial years, there has been no permanent Head of Department; people were only acting in the capacity. vi Even those seconded from national education, could not finish the designated term, because of pressure mainly from the unions.

- Description: The Constitution of the Republic of South Africa guarantees the right of education to all citizens of the country. The Eastern Cape Department of Education went a step further by adopting a vision to ensure quality public education that will result in the positive transformation of all schools. Education is therefore a very important part of the life of any society and needs to be protected at all costs. It is therefore important that all obstacles in the way of providing quality public education be removed. It is no secret that the Eastern Cape Department of Education has had a number of battles with some of its social partners. These battles have negatively impacted on the education system. This Department also received the largest slice of the taxpayers’ money. It is time to take serious steps to halt the waste of time and resources. It is against this background that this study wanted to consider policies, procedures and practices that generated tension between the management and labour in the Eastern Cape Department of Education. It is my belief that if tension between the different social partners can be reduced, we would have gone a long way in achieving the vision of the Department of Education. The research methodology that was followed for this study comprised the following: • Literature was reviewed that dealt with labour relations and human resources. • A questionnaire was designed to collect information from the different participants. • The information in the questionnaire was incorporated into the main study where findings were identified and recommendations were formulated.

- Description: This thesis presents the application of an imprinted mercury(lI) polymer that we synthesized by copolymerizing the functional and cross-linking monomers, N'-[3-(Trimethoxysilyl)propyl] diethylenetriamine (TPET) and tetraethylorthosilicate (TEOS) in the presence of mercury (II) ions as template. A bulk polymerization method following a double-imprinting procedure and employing hexadecyltrimethylammonium bromide (CTAB), as a second template to improve the efficiency of the polymer was employed in the synthesis. The imprinted polymer particles were characterized by Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM) and their average size determined by screen analysis using standard test sieves. The relative selective coefficients (k') of the imprinted polymer evaluated from selective binding studies between Hg ²⁺and Cu²⁺ or Hg²⁺ and Cd²⁺, were 10588 and 3147, respectively. These values indicated highly favored Hg²⁺ extractions over the two competing ions. Application of the polymer to various real water samples (tap, sea, river, pulverized coal solution, treated and untreated sewerage from the vicinity of Grahamstown in South Africa) showed high extraction efficiencies (EEs) of Hg²⁺ ions; (over 84% in all cases) as evaluated from the detected unextracted Hg²⁺ ions by inductively coupled plasma optical emission spectroscopy (ICP-OES). The limit of detection (LOD, 3ơ) of the method was evaluated to be 0.036 ng ml⁻¹ and generally the data (n=10) had percentage relative standard deviation (%RSD) of less than 4%. These findings indicate that the double-imprinted polymer has potential to be used as an efficient extraction material for the selective pre-concentration of mercury(lI) ions in aqueous environments. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: Debate about the extent to which university education should serve industry is an important consideration for institutions of higher learning in a transforming South Africa, and particularly for those teaching would-be journalists. This issue can also be profitably analysed with reference to the current framework of the South African education authorities who argue that the quality of higher education institutions should be measured in terms of their “fit for purpose” to missions aligned to stakeholder interests in the transformation of the country as a whole. This criterion for quality assessment tends to focus on the educative processes within a university, but it can be argued that it ought to extend into the examination of the output consequences of journalism teaching. This would amount to not just fitness for purpose, but also achievement of purpose – and the latter including a creative and critical impact.

Messages from the deep : water divinities, dreams and diviners in Southern Africa

- Description: This thesis is a comparative regional study of a complex of beliefs and practices regarding the water divinities in southern Africa. These snake and mermaid-like divinities, which are said to work in conjunction with one's ancestors, are believed to be responsible for the calling and training of certain diviner-healers by taking them underwater for periods of time. In addition to granting healing knowledge, these divinities are associated with fertility, water and rain, and the origins of humanity. The research combines comparative ethnography with the anthropology of extraordinary experience (AEE), and focuses particularly on the Zulu, Cape Nguni, Shona and Khoisan groups. The use of the 'radical participation' method, as recommended by AEE, was facilitated by the author being identified as having a ' calling' from these water divinities, which subsequently resulted in her initiation under the guidance of a Zulu isangoma (diviner-healer) who had reputedly been taken underwater. The research details the rituals that were performed and how dreams are used to guide the training process of izangoma. This resulted in the research process being largely dream-directed, in that the author traces how the izangoma responded to various dreams she had and how these responses opened new avenues for understanding the phenomenon of the water divinities. The comparative study thus combines literature sources, field research and dream-directed experiences, and reveals a complex of recurring themes, symbols and norms pertaining to the water divinities across the selected groups. In seeking to explain both the commonalities and differences between these groups, the author argues for a four-level explanatory model that combines both conventional anthropological theory and extraordinary experience. Responses to the author's dream-led experiences are used to throw light on the conflicting discourses of morality regarding traditional healers and the water divinities in the context of political-economic transformations relating to capitalism and the moral economy; to illuminate the blending of ideas and practices between Zulu Zionists and diviner-healer traditions; and to link up with certain issues relating to San rock art, rain-making and healing rituals, which contribute to the debates regarding trance-induced rock art in southern Africa.

- Description: Two pocket sandy beaches, Eastern Cape, South Africa, were investigated, to determine whether these beaches were subsidised by an adjacent mangrove estuary, by using stable light isotope (δ 13C and δ 15N) analyses. The trophodynamics and macrofaunal food webs of these two beaches, situated between the Mgazi and Mgazana estuaries (in a warm-temperate/subtropical transition zone,), were described. Two to 2.5 trophic levels were identified for the macrobenthic community, with suspension feeders and omnivorous scavengers as the primary consumers, and carnivores as the secondary consumers. Mangrove material and terrigenous inputs were not driving the sandy beach food webs. Instead, marine allochthonous inputs (carrion, macroalgae), possibly phytoplankton, sediment organic matter, and resident macroinfauna were the dominant food sources. Cattle dung could have been the only important terrigenous food source utilised by the beach benthos. The macroinfauna displayed generalist/omnivorous feeding strategies, but within the limits of predominantly marine food sources. There was evidence that carnivores actively preyed on resident beach fauna. Omnivory and intraguild feeding might also be important biological processes in these communities. Seasonal and spatial variability in stable isotope composition of the fauna was observed, but few patterns were evident. There was a general trend of more enriched δ 15N and δ 13C composition of animal tissues in summer as opposed to winter. This was accompanied by a general decrease in C:N ratios in summer. It was hypothesised that these isotopic and biochemical changes were in response to increased food availability during summer. Although mangrove material appeared not to play an important role in the nutrition of these sandy beach communities, it was suggested that a high retention time of particles in the bay could enhance bacterial decay of particulate mangrove material, which could then act as fine, bacterial-enriched particulate food to the macrobenthos. This remains to be tested.

- Description: In observing and plotting the dialectics of how our present world works, fragmenting as it integrates we struggle in wanting to pin down a moving target! Unlike the world of science with its physical laws, the social nature of the world and its relations across borders keep changing course with social and transnational relations constantly mutating. This makes it rather difficult to plot the complexity of human relations, also those across borders. As the late Nobel Laureate Herbert Simon once said, the social sciences are, after all, the really ‘hard’ sciences. They are so hard because they are so hard to explain.

- Description: Currently some confusion exists as to how health professionals should best respond to the psychological needs of those affected by disasters. Some have argued that early psychological intervention is essential and others have argued that early formal psychological interventions have no useful role in post trauma response. This study highlights the importance of considering both counselling and non-counselling factors as potentially influencing the psychosocial response of disaster victims. Although posttraumatic stress disorder (PTSD) is not the only mental disorder that can develop as a result of exposure to disasters, it is probably the most frequent and debilitating psychological disorder associated with traumatic stress. In this exploratorydescriptive study the researcher aimed to explore and describe psychologists’ perceived influences of early strategies on the psychosocial response to those affected by disaster. The researcher used non-probability snowball sampling to access participants. The sample consisted of 5 participants. Semi structured interviews were conducted. Content analysis was used to analyse the data obtained from interviews. Results that emerged from the data suggest that there are many factors that influence the psychosocial response to those affected by disasters. These factors include the screening process, needs of survivors, the method of choice for treatment, the timing of intervention, pharmacology, the South African context, training and planning. The study makes a contribution to the growing knowledge of early strategies in response to those affected by disasters.

- Description: The spatial and temporal patterns in selected components of the ichthyofauna and piscivorous avifauna in the small temporarily open/closed Riet River Estuary located on the eastern seaboard of southern Africa was investigated monthly over the period August 2005 to July 2006. The ichthyofauna within the littoral zone of the estuary was sampled using a 5 m seine net (8 stations) while a 30 m seine net (4 stations) was employed to sample the fish in the channel. Bird counts were made along repeat transects along the length of the estuary. Total ichthyofaunal abundances and biomass ranged between 1.60 and 8.67 individuals m⁻² and 0.45 to 21.76 g wwt m⁻² within the littoral zone, and between 0.08 and 0.44 individuals m⁻² and 0.58 and 36.52 g wwt m⁻² in the channel of the estuary. The highest values were generally recorded during the summer months. Results of the numerical analysis indicated that the breaching events recorded over the study period did not lead to a common trend in the ichthyofaunal community. In the absence of a link to the marine environment, the ichthyofaunal community in the littoral zone was numerically dominated by the estuarine resident species, Gilchristella aestuaria and to a lesser extent by Glossogobius callidus, which collectively accounted for ca. 54% of the total ichthyofauna sampled. The establishment of a link to the marine environment coincided with increased numbers of marine breeding species including Atherina breviceps and Rhabdosargus holubi to total fish counts within the estuary. Hierarchical cluster analysis did not identify any spatial patterns in the community structure of the ichthyofauna in the littoral zone or channel zone of the estuary, which could likely be linked to the absence of any distinct horizontal patterns in salinity and temperature within the system. A total of thirteen piscivorous bird species was recorded over the study period. Of the recorded species, six species were wading piscivores, four species were aerial divers and the remaining three species were pursuit swimmers. There were no significant correlations between the estimates of the ichthyofaunal abundance and biomass and bird numbers evident during the study (P> 0.05 in both cases). The Reed Cormorant (Phalacrocorax africanus) was the dominant species throughout the study, with a mean of 8.25 (SD ± 7.90) individuals per count. Mean values of the Pied Kingfisher (Ceryle rudis) and Giant Kingfisher (Megaceryle maximus) were 3.42 (SD ± 1.20) and 1.17 (SD ± 0.60) individuals per count, respectively. The remaining species revealed mean values < 0.5 individuals per count. The highest bird numbers were recorded in winter reflecting the migration of large numbers of the Reed Cormorant into the system. Breaching events were associated with a decrease in total bird numbers, which was most likely due to loss of potential foraging habitat (littoral zone) for waders resulting from reduced water levels. Monthly food consumption by all piscivorous birds revealed large temporal variability, ranging from 26.35 to 140.58 kg per month. The observed variability could be linked to mouth phase and bird numbers.

- Description: In South Africa the pharmacy profession has experienced a number of changes around the turn of the century such as the introduction of the National Drug Policy (NDP), pharmacy ownership and price regulation. With this the role and earnings of the pharmacy profession, as well as to what extent the pharmacist adds value to the profession and society, are being questioned. Community pharmacists are thus faced with the challenge to prove that the value that they add to society is meaningful. Therefore, the aim of the study was to document community pharmacy availability and activities in South Africa and based on this to quantify the perceived value that the community pharmacist adds to society through the delivery of pharmaceutical services and pharmaceutical care. In order to determine the pharmacist’s true value added two surveys were conducted in 2006; an original pharmacist survey and a general public survey. The results obtained were verified by a follow–up pharmacist survey in 2009 to confirm or reject the results obtained in the original survey. The study was representative of both the community pharmacies and the general public in South Africa and was primarily quantitative in design and analysis. More than half of the responding pharmacies (63.16%) were open seven days a week. The average hours of service per day ranged from 10 hours (Monday to Friday) through to 6.45 hours on Saturdays and 3 hours on Sundays. Pharmacists continuously upgraded their professional knowledge. More than three quarters of pharmacies had the necessary equipment available to perform the services investigated in the study. The general public was not aware of all the services provided by pharmacists and as a result, depending on the service, many people did not make use of these services. The general public that made use of services delivered by community pharmacies mainly perceived the services delivered to be of good quality. The main barrier to practicing pharmaceutical care was indicated by pharmacists as not receiving payment for the advice given followed by pharmaceutical care being time consuming, and that there was not enough time to talk to patients. The general public indicated that they found it difficult to ask questions in pharmacies because other patients could hear what was discussed, or other patients had to wait longer if they asked something, and pharmacy staff being too busy. The results of the original pharmacist and the general public survey were confirmed by the results of the follow-up survey with the exception of dispensing prescription medicine (8 minutes 28 seconds), OTC medicine (7 minutes 23 seconds), counselling of prescription medicine (8 minutes 51 seconds) and OTC medicine (8 minutes) which on average took longer to conduct than in the previous analysis. The study highlighted the value added to the wellness and quality of life of the community of South Africa through the delivery of pharmaceutical care and pharmaceutical services by community pharmacy staff, and proved that pharmacists are committed to the provision of pharmaceutical care and pharmaceutical services.

- Description: Internationally there is an increasing focus on involving local communities in natural resource management and monitoring. Monitoring methods which are professionally driven appear to be inadequate to deal with the monitoring of natural resource use and biodiversity conservation, globally. This is especially evident in areas such as South African rural communal land. Two community based natural resource management (CBNRM) programmes in areas which are communally governed in the Eastern Cape, South Africa, namely Nqabara and Machubeni, were used as part of this research study. This thesis identified and tested potentially simple and cost effective monitoring methods related to the utilization of the local rangelands and indigenous forests. The criteria that were tested include 1) appropriateness and effectiveness in measuring change, and 2) contribution to building adaptive capacity among local land managers through learning. The criteria were assessed using a scoring system for each monitoring method in order to evaluate their strengths and weaknesses . This was done by using both quantitative and qualitative data. Contribution to building adaptive capacity was assessed by evaluating technical capacity gained, local ecological knowledge contributed and learning by participants. This was done using qualitative data. The results show that the monitoring methods had different strengths and weaknesses in relation to the criteria, making them more appropriate for different priorities such as effectively measuring change or building adaptive capacity. It is argued that an adaptive approach is a useful component in the participatory monitoring process. An adaptive framework was developed from lessons learnt in this study for collaborative monitoring. Challenges such as low literacy levels and adequate training still need to be addressed to strengthen efforts towards participatory monitoring. Factors such as incentives, conflict and local values may negatively affect the legitimacy and sustainability of participatory monitoring and therefore also need to be addressed.

- Description: Children are placed in a children’s home when a Presiding Officer finds them to be in need of care and when there is no viable community placement alternative. The body of literature on children’s homes focuses primarily on the negative effects and outcomes of such statutory placement. The assertion that children who grew up in children’s homes will continue to use the services of welfare organisations in adulthood, is supported by the researcher’s observation as a practicing social worker. This, and the study of available literature, resulted in this qualitative, exploratory-descriptive and contextual research study with the following goal: to enhance the understanding of how intervention programmes at children’s homes can contribute to adult adjustment and independent functioning of those children in their care. A purposive sampling method was used to identify ten participants who had spent at least 2 years in a children’s home and who had been discharged from the children’s home at least 5 years ago (to the date of data collection). The sample was drawn from clients at non governmental social welfare agencies who fitted the sampling criteria. The data was collected via semi-structured interviews using an interview guide, which were recorded, transcribed and then analysed using a thematic content analysis approach. The results of the study may be used to develop and implement meaningful intervention strategies for individuals placed in children’s homes.

- Description: This thesis analyzes rape coverage in a Grahamstown newspaper, Grocott’s Mail. Critical discourse analysis is used to discuss and analyze articles about rape that appear in Grocott’s Mail between October 14th 2008 and October 29th 2009. Drawing on existing literature on ‘rape myths’ in media coverage of rape, this thesis argues that Grocott’s Mail perpetuates racial and gender stereotypes through the way in which it reports on rape. While not all of the articles included in the analysis use rape myths, most use one or more when discussing rape incidents. Specifically, Grocott’s Mail tends to use rape myths that blame the victim for the rape and de-emphasize the role of the perpetrator in the rape. This is problematic as it sustains existing racial and gender inequalities.

- Description: Local economic development (LED) in the countries of the North is a voluntary activity of local government, in South Africa it is a mandatory activity. The purpose of LED is to build the capacity of a local area to improve its economic future and the quality of life for all. While local governments in South Africa are currently engaged with the concept of LED which is seen as a tool through which to achieve sustainable development, it is now recognized that there exists economic, social and environmental interdependence between rural and urban areas and a need for a balanced and mutually supportive approach to development of the rural and urban areas. Adopting the Rural-Urban, Economic and Enterprise Development (RUEED) concept, this study highlights the challenges and development problems experienced by the deep rural and urban communities in the implementation of LED activities within the Blue Crane Route Municipality (BCRM) due to the lack of social, economic and environmental sustainability and rural-urban linkages. This study located in the Blue Crane Route Municipality in the Eastern Cape, seeks to investigate and recommend a map or strategies linking together the urban communities with the poorer neighbourhoods in LED activities. The intensive research design that incorporates the case study method was used to achieve the objectives of this study. The empirical findings of the research indicate that the concept of rural-urban linkages is not an adopted strategy in implementing development programmes resulting in deep rural communities being excluded in LED activities initiated within the Blue Crane Route Municipality. The findings also reveal that the creation of employment opportunities and improvement in the standard of living are important dimensions of LED and rural-urban linkages. This study therefore recommends the adoption of a new perspective referred to as the rural-urban linkages for LED and the consideration of economic, social and environmental complementaries that exist between rural and urban areas in the Blue Crane Route Municipality. The study further indicates that it is critical that the LED policy and interventions reflect the existing patterns of interactions between the rural and urban areas of the Municipality.

- Description: Histological examination of gametogenesis revealed that the current staging criteria used to assess gonadal recrudescence of the redeye labeo, Labeo cylindricus, were adequate. Gametogenesis was qualitatively similar to that of freshwater teleosts with a clearly defined seasonal reproductive cycle. L. cylindricus undergoes seasonal gross morphological and cytological gonadal changes with previtellogenesis dominating during the winter, vitellogenic development during spring and summer culminating in large-scale spawning at the end of summer. Post-spawning mass atresia of oocytes was evident in autumn. The histological data presented support macroscopical evidence that L. cylindricus is a synchronous iteroparous spawner, reproducing over a short period each year throughout its life-span.
