- Description: The extensive amount of research conducted in the field of family violence internationally indicates that child abuse has a detrimental effect on both the physical and emotional development of children as well as having a profound effect on an individual’s psychological development and functioning in adult life. The aim of this research study was to describe the therapeutic process that unfolded with a seven year old allegedly abused female client within the framework of non-directive play therapy. The case was further contextualised utilising Erik Erikson’s theory of psychosocial development. This study served to broaden the body of psychotherapeutic knowledge by means of meaningful qualitative enquiry. The client was referred for therapy because of severe emotional and behavioural problems following the alleged sexual abuse. The client was seen over a period of eight months and this included 11 sessions of non-directive play therapy, three parent interviews and psychometric assessments conducted by a colleague. The case study method was utilised in this study. To achieve the aim of the research, the methodology of choice was the descriptive dialogic case study. A purposive sampling technique was used in the selection of the research subject for this study. The data collection and analysis were conducted according to Yin’s (1994) analytical generalisation, which consists of two main strategies: (a) using a theoretical framework as a guide to determine what data is relevant; and (b) developing a matrix as a descriptive framework for organising and integrating the data. Furthermore, the process of data analysis was aided by the use of guidelines proposed by Irving Alexander (1988) with Axline’s non-directive play therapy and Erikson’s theory of psychosocial development as the theoretical frameworks. The findings of this study suggest that plotting the play therapy sessions according to the framework of the four stages of play therapy was a particularly useful tool to monitor Michelle’s progression through the therapeutic process. This can be seen as a valuable application of a tool which can be used within the non-directive play therapy approach. Contextualising Michelle’s development according to the stages of Erikson’s theory of psychosocial development was also found to be a valuable endeavour. According to her chronological age, Michelle should have been in the fourth stage of industry versus inferiority, but in reality Michelle was still struggling to strike a healthy balance between the terms of conflict of trust versus mistrust issues of the first stage. From a therapeutic point, this was an important exercise as it helped to inform the therapist and consequently, the therapeutic process. This research undertaking can be recognised as a positive demonstration of the value of non-directive play therapy (Virginia Axline) and Erik Erikson’s theory of psychosocial development in the therapeutic process. In addition, this study has served to facilitate a more holistic understanding of the case study approach to research. Recommendations regarding future research undertakings that utilise the case study approach and methodology have been made. Key concepts: child abuse; family violence; non-directive play therapy; Erik Erikson’s theory of psychosocial development; analytical generalisation; case study research.

- Description: The learning and analysis of algorithms and algorithm concepts are challenging to students due to the abstract and conceptual nature of algorithms. Algorithm animation is a form of technological support tool which encourages algorithm comprehension by visualising algorithms in execution. Algorithm animation can potentially be utilised to support students while learning algorithms. Despite widespread acknowledgement for the usefulness of algorithm animation in algorithm courses at tertiary institutions, no recognised framework exists upon which algorithm animation systems can be effectively modelled. This dissertation consequently focuses on the design of an extensible algorithm animation framework to support the generation of interactive algorithm animations. A literature and extant system review forms the basis for the framework design process. The result of the review is a list of requirements for a pedagogically effective algorithm animation system. The proposed framework supports the pedagogic requirements by utilising an independent layer structure to support the generation and display of algorithm animations. The effectiveness of the framework is evaluated through the implementation of a prototype algorithm animation system using sorting algorithms as a case study. This dissertation is successful in proposing a framework to support the development of algorithm animations. The prototype developed will enable the integration of algorithm animations into the Nelson Mandela Metropolitan University’s teaching model, thereby permitting the university to conduct future research relating to the usefulness of algorithm animation in algorithm courses.

- Description: The purpose of the study is to evaluate the service quality that the SANBS provides to its customers, by measuring customers’ perceptions and their expectations of service quality provided by the supplier of blood transfusion services. The organization that is used for this study is the South African National Blood Service (SANBS). Specifically the study seeks to: 1. Determine the extent to which customers are satisfied or not satisfied with the service they receive from the SANBS using the ten-dimensional format of SERVQUAL model, modified to the specific service quality requirements of the blood transfusion service industry. 2. Establish customers’ perceptions of the service they receive using a multiple-item scale (SERVQUAL) for measuring consumer perceptions of service quality. 3. Establish customers’ expectations of the service, and compare them to their perceptions of the service they currently receive. The comparison is made along each service quality dimension, across different parts of same service on a geographical basis, and across different customer groups on a customer category (or type) basis. 4. Recommend implementation of appropriate service quality performance improvement procedures where necessary. Study design and methods: The data for the study came from the SANBS’ customer perception and expectation survey conducted in 2005. Questionnaires were sent out to hospitals that use products and services provided by the SANBS in the Eastern Cape and KwaZulu-Natal Provinces of South Africa. The questionnaire was based on the multiple-item SERVQUAL model for measuring consumer perceptions of service quality, modified and tailored to specific service quality requirements of the blood transfusion service industry. Questionnaires were sent out to 113 (69.3%) hospitals out of a total of 163 blood-utilizing hospitals in the two provinces. Of the 113 hospitals, 92 (81.4%) responded, with questionnaires rendered unusable. The final sample size is 88 and is included in the final study database. The data is analyzed by comparing different parts of the service on a geographical basis namely KwaZulu-Natal and Eastern Cape zones. The data is also analyzed by comparing different customer groups namely the Rural State Hospitals, the Urban State Hospitals and Private Hospitals. Results: The result confirms the research (alternative) hypothesis (H1 : μ1 ≠ μ2), and rejects Ho. The overall expectations ratings are higher than the perceptions ratings, and the KwaZulu-Natal expectations ratings are higher than the Eastern Cape ratings. The expectations of private hospitals and rural state hospitals have a higher rating than that of urban state hospitals and the perceptions of private and urban state hospitals have a higher rating than that of rural state hospitals. The largest service quality gap is the accessibility dimension which relates specifically to approachability and ease with which customers can access staff at different levels of the organization by e-mail, and includes accessing of knowledgeable blood bank personnel and medical staff of SANBS, but may also relate to the distance of hospitals from the nearest blood bank, all of which are situated in urban state hospitals. The mean difference for accessibility is the highest followed by the understanding customer mean difference. The mean differences for the other dimension categories are significantly less than that of the largest two dimensions, but not significantly different amongst themselves. The mean difference for rural state hospitals is the largest followed by private hospitals and urban state hospitals. The mean difference for rural state hospitals is greater than that for urban state hospitals in both zones, but the mean difference for private hospitals is greater in KwaZulu-Natal than in the Eastern Cape. The dimension means of differences for rural state hospitals are greater than that for urban state hospitals. According to the correlations between expectations and perceptions for different dimensions, there is a weak or no linear relationship between expectations and perceptions. Conclusion: This empirical study supports the literature on the provision of service quality, and concludes that there is a statistically significant difference or gap between the services offered by the SANBS as perceived by its customers, and the expectations of its customers. The study substantiates the need for management of blood transfusion services to take into account customer perceptions of service quality and their expectations, and upon identification of gaps, to implement appropriate service quality improvement processes, rather than take a one sided view of their (SANBS’) own perception of service quality.

Blogging, journalism and the public sphere: assessing the value of the 'blogosphere' as a new form of the public sphere : a case study of the Mail & Guardian Online's Blogmark

- Description: The study seeks to investigate whether weblogs can act as virtual public spheres, where people can meet to discuss issues of interest to them. It uses the Mail & Guardian Online’s Blogmark as a case study. Weblogs – highly interactive online journals comprised of links and postings in reverse chronological order – are fast becoming an avenue of choice for many internet users wanting to share opinions and news with others online. Because of their unique read-and-write characteristics, some have equated them to the 18th century coffeehouses, around which the early forms of citizen involvement in public affairs began in early capitalist Europe. Despite their growing popularity, however, not much scholarly work has been dedicated to the practice of blogging in Africa, and particularly in South Africa. The study’s theoretical framework is drawn from Jürgen Habermas’s concept of the public sphere. While noting some of the criticisms of the Habermasian model, it is argued that the concept is instrumental in our understanding of the relationship between the media and democracy. The study, however, adopted a re-worked model of the concept of the public sphere. This model argues for the need to have a multiplicity of public sphericules (instead of one single public sphere as advocated by Habermas), around which individuals can congregate to discuss issues of common concern to them. Using a combination of qualitative content analysis, self-completion questionnaires and a semi-structured interview, the study found Blogmark to be an example of how emerging internet genres such as weblogs can be vehicles of citizen involvement in public life. A range of issues were discussed in the blog, from politics, race and ii i gender issues, to personal anecdotes, relationships, and sex. However, while some posts exhibited high levels of interactivity, with many bloggers joining in to offer their opinions, some read like online monologues. The study argues that although blogging is a practice that is still limited to a few privileged individuals, with the everrising size of the ‘blogosphere’, weblogs such as Blogmark are making a small but not insignificant contribution to the number of voices that can be heard in the public realm.

- Description: Arbor Day, or Week, is a well-established greening initiative worldwide, focusing on tree planting and the benefits thereof. Frequently most effort is targeted at institutions such as schools and community groups. Yet there has been limited assessment of the success of Arbor Day, or Week, activities both at the schools, or the wider dissemination in neighbouring communities and suburbs. The objective of this study was to determine the influence of school-based Arbor Week activities on learners’ home-based practices regarding tree planting and urban forestry. Learners from three schools in Grahamstown South Africa, with good Arbor Week participation, were assessed on their tree planting knowledge. The learners’ parents were also interviewed to determine whether the information obtained by the learners at school was taken home. A control group consisting of people with no children or very young children was also assessed. This study found that Arbor Week activities were, for the most part, successfully taught in the case study schools, and most of the learners stated that their knowledge of trees and their benefits came from their school activities. However, many learners could not remember the activities in which their schools partook the previous year. Whilst most learners were aware of the importance of trees, few had encouraged tree planting at home. However, over one-fifth of adults claimed that their knowledge of the benefits of trees was as a consequence of Arbor Day activities when they were young. Numerous constraints to tree planting were provided by learners and both the adult groups, the two most frequent being limited space and falling leaves making their yards untidy. External organisations should become more actively involved and provide much needed support systems if greening initiatives are to reach the wider community.

- Description: The thesis presents a qualitative survey of web services' interoperability, offering a snapshot of development and trends at the end of 2005. It starts by examining the beginnings of web services in earlier distributed computing and middleware technologies, determining the distance from these approaches evident in current web-services architectures. It establishes a working definition of web services, examining the protocols that now seek to define it and the extent to which they contribute to its most crucial feature, interoperability. The thesis then considers the REST approach to web services as being in a class of its own, concluding that this approach to interoperable distributed computing is not only the simplest but also the most interoperable. It looks briefly at interoperability issues raised by technologies in the wider arena of Service Oriented Architecture. The chapter on protocols is complemented by a chapter that validates the qualitative findings by examining web services in practice. These have been implemented by a variety of toolkits and on different platforms. Included in the study is a preliminary examination of JAX-WS, the replacement for JAX-RPC, which is still under development. Although the main language of implementation is Java, the study includes services in C# and PHP and one implementation of a client using a Firefox extension. The study concludes that different forms of web service may co-exist with earlier middleware technologies. While remaining aware that there are still pitfalls that might yet derail the movement towards greater interoperability, the conclusion sounds an optimistic note that recent cooperation between different vendors may yet result in a solution that achieves interoperability through core web-service standards.

- Description: Fuelwood is the primary energy for most households throughout the developing world. With increasing urbanization and declining local availability of fuelwood, a growing proportion of households obtain their fuelwood by purchasing it. These fuelwood markets are the key nexus in supply and demand scenarios and can be potentially significant points for intervention to address energy security amongst the urban poor. This paper reports on the fuelwood demand and marketing in a small town in South Africa. Despite the availability of more modern fuels and state subsidization of electricity, fuelwood was still used by half the households. Annual demand was 1.2 t per household. Over half of the households bought their fuelwood requirements because local stocks were limited. Those households that did collect their own fuelwood were significantly poorer than households that purchased fuelwood, as well as households that did not use fuelwood at all. Fuelwood markets operated through 45-60 vendors who transported fuelwood from further afield. Income from the fuelwood trade was low, but was strongly linked to hours worked. Thus, vendors working a full week did earn a meaningful income, especially in the context of high unemployment in the area. Fuelwood vendors also provided casual employment opportunities for unskilled labour. Most vendors harvested fuelwood from commonage lands, with most of the wood being from alien species. Local stocks of wood are declining in the face of constant transformation of commonage to residential areas, and a national water and biodiversity conservation programme to eradicate alien plants. This decline poses a threat to the financial viability of fuelwood markets. Yet, an opportunity exists to incorporate the vendors into the alien plant clearing programme, since they already perform such a function.

- Description: This thesis takes the form of an in-depth case study within which the play therapy process of an aggressive 5-year-old boy was explored. The aim of the research was to examine the abundant expressions of aggression that were present within his therapy, and in so doing reflect their rich communicative content and their relevance and purpose in the development of his Self. Object relations theory formed the lens and theoretical context for this research with Winnicott’s contributions and Parens' model of aggression being considered in particular. A detailed data resource of the therapy process was compiled and transposed into narrative form. These narratives were reviewed with a reading guide as a means to facilitate a hermeneutic exploration of the data. The emergent themes were considered against the case data and the current theory, which allowed for their further analysis and development. From this the value of using Parens’ model was considered and deemed useful although limited in its contribution. The analysis and the themes which emerged conveyed how within this case the child’s aggression presented as: a significant feature of his ambivalence towards relationships; a powerful and pervasive protective fantasy of omnipotence; inherently linked to his sense of self and self expression; and as actively involved in his True Self’s hope-filled attempts for an alternative experience. This thesis provides a descriptive account of a challenging case, offering insights into the value and meaningful content of aggressive behaviours, with the intention being to reflect that which is often not easily appreciated or readily observable within such a therapy process, a trace of hope.

- Description: Evidence that the environmental Kuznets curve (EKC) may be explained by trade patterns casts doubt on the oft‐stated conclusion that economic growth automatically leads to environmental improvement. Trends in net exports as a proportion of consumption for both USA and UK trade with SACU were examined for various dirty industries. Some evidence of pollution haven effects is found, although a similar trend for clean industries suggests that this effect is weak. However, even a general shift in manufacturing industries from North to South (as opposed to a shift in specifically dirty industries) may explain the EKC to some extent.

- Description: The Palaeoproterozoic Earth experienced a global glacial event at 2400 Ma that occurred during the transitional period from anoxic to aerobic conditions in the atmosphere and oceans. The Transvaal Supergroup in the Griqualand West Basin, South Africa, hosts glacial deposits and associated major iron and manganese deposits that are apparently related to these global changes. The focus of this study is to assess the stratigraphy and geochemistry of the glaciogenic Makganyene Formation, in order to constrain its palaeoenvironmental settings. The Makganyene Formation forms the base of the Postmasburg Group and has been regarded as resting on an erosive regional unconformity throughout the Northern Cape Province. Systematic regional field observations and regional mapping carried out during this study demonstrate that this stratigraphic relationship is not universal. The Makganyene Formation is, in fact, conformable with underlying formations of the Koegas Subgroup in the deep southern Prieska basin and rests on an unconformity only on the shallow Ghaap platform to the north-east. The Makganyene Formation displays lateral facies changes that reflect the palaeogeography of the study area, and the advance and retreat of ice sheets/shelves. Geochemical investigations of glacial strata of the Makganyene Formation demonstrate that underlying banded iron formations of the Transvaal Supergroup acted as the main clastic source for the diamictite detritus. Geographic variations in bulk composition of the diamictites correlate well with field observations, and show that sorting processes were controlled largely by the morphology of the palaeobasin. Carbon isotope results emphasize the transitional nature of the Makganyene Formation in terms of the environmental conditions that resulted in widespread global glaciation in the Palaeoproterozoic. On the basis of the above geological evidence, it is proposed that the Transvaal Supergroup in the Northern Cape Province represents a continuous depositional event that lasted approximately 250 Ma and hence provides a unique opportunity for assessing the transitional changes experienced by the Palaeoproterozoic Earth.

An insight into magma supply to the Karoo Igneous Province a geochemical investigation of Karoo dykes adjacent to the Northwestern sector of the Lesotho volcanic remnant

- Description: The emplacement of continental flood basalt provinces is often ascribed to fissure eruption. However, in many provinces the locations of actual vent complexes remains illusive. In southern Africa, the Karoo continental flood basalt province was erupted during the Jurassic between 183 and 179 Ma. The southernmost outcrop of the Karoo continental flood basalt lavas is the Lesotho remnant; and is comprised of the Drakensberg Group which forms the uppermost portion of the Karoo Supergroup. The geochemical stratigraphy for the Drakensberg Group is well established. At the base, there are a number of small volume compositionally diverse units, which form the Barkly East Formation, overlying which, there are larger volume, compositionally less variable units of the Lesotho Formation, which form the bulk of the volcanic sequence. The Lesotho remnant is associated with an abundance of dykes in the adjacent vicinity. This suggests that the lavas were fed from local rather than distal eruption sites. This study presents whole rock major and trace element data for 94 dykes and three sills from the northern Lesotho - northeastern Free State region and demonstrates that on the basis of geochemistry, all 97 intrusions can be correlated with various units of the northern Barkly East and Lesotho Formations. In addition, the petrographical; characteristics, orientation and distribution of the dykes do not correlate with geochemistry. Geochemical discrimination diagrams have been used to identify five compositionally diverse dykes, which are similar to the northern Barkly East Formation units. Three dykes are characteristic of the Letele unit and two are compositionally similar to the Wonderkop unit. Although the geochemical characteristics of the Lesotho Formation units are rather well constrained, the composition of these units is typified by considerable overlap in composition. Therefore, since unambiguous classification of dykes with geochemical similarities to the various units of the Lesotho Formation is unachievable using an empirical approach, the multivariate forward-stepwise discriminant function analysis (DFA) technique was used to facilitate the classification of the remaining 89 dykes and three sills. Forward-stepwise DFA classified 23 dykes as having compositional similarities to the Mafika Lisiu unit, 29 as having compositions of the Maloti or Senqu types; and 32 as having the composition of the Mothae type. In addition, eight dykes are compositionally similar to the Oxbow dykes, which intrude the Senqu unit in northern Lesotho. These results suggest that that the Lesotho remnant was fed from local eruption sites and that long distance magma transport for the bulk of the Lesotho remnant basalt lavas is unlikely.

The geochemical stratigraphy for the Drakensberg Group is well established. At the base, there are a number of small volume compositionally diverse units, which form the Barkly East Formation, overlying which, there are larger volume, compositionally less variable units of the Lesotho Formation, which form the bulk of the volcanic sequence. The Lesotho remnant is associated with an abundance of dykes in the adjacent vicinity. This suggests that the lavas were fed from local rather than distal eruption sites. This study presents whole rock major and trace element data for 94 dykes and three sills from the northern Lesotho - northeastern Free State region and demonstrates that on the basis of geochemistry, all 97 intrusions can be correlated with various units of the northern Barkly East and Lesotho Formations. In addition, the petrographical; characteristics, orientation and distribution of the dykes do not correlate with geochemistry. Geochemical discrimination diagrams have been used to identify five compositionally diverse dykes, which are similar to the northern Barkly East Formation units. Three dykes are characteristic of the Letele unit and two are compositionally similar to the Wonderkop unit. Although the geochemical characteristics of the Lesotho Formation units are rather well constrained, the composition of these units is typified by considerable overlap in composition. Therefore, since unambiguous classification of dykes with geochemical similarities to the various units of the Lesotho Formation is unachievable using an empirical approach, the multivariate forward-stepwise discriminant function analysis (DFA) technique was used to facilitate the classification of the remaining 89 dykes and three sills. Forward-stepwise DFA classified 23 dykes as having compositional similarities to the Mafika Lisiu unit, 29 as having compositions of the Maloti or Senqu types; and 32 as having the composition of the Mothae type. In addition, eight dykes are compositionally similar to the Oxbow dykes, which intrude the Senqu unit in northern Lesotho. These results suggest that that the Lesotho remnant was fed from local eruption sites and that long distance magma transport for the bulk of the Lesotho remnant basalt lavas is unlikely.

- Description: Evidence suggests that the prevalence of certain non-communicable diseases, such as hypertension, is increasing rapidly, and that patients with these diseases are making significant demands on the health services of the nations in sub-Saharan Africa. However, these countries also face other health-related challenges such as communicable diseases and underdevelopmentrelated diseases. Developing countries like South Africa have limited resources, in terms of man power and financial capital, to address the challenges that they are facing. Non-communicable diseases cannot be ignored and since health care providers cannot meet the challenges, it is worthwhile to empower patients to be involved in the management of their conditions. Patient education is a tool that can be used to enable patients to manage their chronic conditions and thereby reduce the morbidity and mortality rates of these conditions. The aim of this study was to investigate the effect of a patient education intervention on participants’ levels of knowledge about hypertension and its therapy, beliefs about medicines and adherence to anti-hypertensive therapy. The intervention consisted of talks and discussions with all the participants as one group and as individuals. There was also written information given to the participants. Their levels of knowledge about hypertension and its therapy were measured using one-on-one interviews and self-administered questionnaires. Beliefs about medicines were measured using the Beliefs about Medicines Questionnaire (BMQ) whilst adherence levels were measured using pill counts, elf-reports and prescription refill records. The participants’ blood pressure readings and body mass indices were also recorded throughout the study. The parameters before and after the educational intervention were compared using statistical analyses. The participants’ levels of knowledge about hypertension and its therapy significantly increased whilst their beliefs about medicines were positively modified after the educational intervention. There were also increases, though not statistically significant, in the participants’ levels of adherence to anti-hypertensive therapy. Unexpectedly, the blood pressure readings and body mass indices increased significantly. The participants gave positive feedback regarding the educational intervention and indicated a desire for similar programmes to be run continuously. They also suggested that such programmes be implemented for other common chronic conditions such as asthma and diabetes. This study proved that patient education programmes can be implemented to modify patients’ levels of knowledge about their conditions and the therapy, beliefs about medicines and adherence to therapy. However, such programmes need to be conducted over a long period of time since changes involving behaviour take a long time.

- Description: Since 1994, South Africa has witnessed the fundamental transformation and restructuring of its Higher Education Sector. The restructuring of Higher Education Institutions in the Eastern Cape Province is manifested by inter alia the incorporation of the Port Elizabeth branch of the Vista University into the University of Port Elizabeth as a first phase and, as the final phase, the merger between the University of Port Elizabeth and the Port Elizabeth Technikon. A new, comprehensive university, the Nelson Mandela Metropolitan University (NMMU), emerged from this merger on 1 January 2005. The previous institutions each had its own unique brand identity, brand image and brand name. With reference to the newly established NMMU, the question can be raised whether the brand identity of this newly established institution impacts on its perceived brand image among all stakeholders who have an interest in the institution. Given the merger background, the purpose of this research project is twofold: firstly, to analyse the impact of independent variables (‘reputation’, ‘relevance’, ‘personality’, ‘performance’ and ‘relationship’) on brand identity (moderating variable) and the impact of brand identity on brand image (dependent variable); and secondly, to gauge the perceptions of NMMU stakeholders of the brand image of the University in terms of both expectations and actual experiences. In order to give effect to the above, a conceptual model on brand identity and brand image based on secondary sources on branding, was empirically tested. Given the purpose and nature of the research in question, a positivistic research paradigm was adopted. By means of a Likert seven-point scale, primary data was sourced from 1 092 respondents, who shared their perceptions on the expectations and actual experiences of using the NMMU brand. The statistical analysis of the data comprised six phases. Initially, the data was subjected to an exploratory factor analysis to assess the discriminant validity of (xvi) the research instrument. This was followed by an assessment of the reliability of the research instrument through an internal consistency measure (Cronbach alpha reliability coefficients). The items that remained were included in the multiple regression model to assess the impact of brand identity variables on brand identity. The next phase comprised a regression analysis of the impact of brand identity on brand image. Fifthly, to assess any differences between stakeholders’ expectations and actual experiences when using the NMMU brand, pair-wise t-tests were performed. Finally, to gauge the level of satisfaction of NMMU stakeholders when using the brand, a “gap” analysis was conducted by converting the mean scores into relative percentage ratings. The empirical findings did not fully support the conceptual model. The testing of the conceptual model revealed that the independent variable ‘relevance’ did not demonstrate sufficient discriminant validity and, as a result, no evidence of construct validity. This variable therefore had to be removed from the conceptual model before it was subjected to further empirical assessment by means of the multiple linear regression analysis. Based on this finding on ‘relevance’, NMMU marketing communication strategists could perform an in-depth investigation on the positioning of the brand. Further, it was found that the dependent variable ‘brand image’ was not a uni-dimensional construct as suggested in the conceptual model. Ideally, images (in this case, brand images of the NMMU) should feed into strategic vision, serving as a mirror in which a university can reflect on its true standing. This implies that instead of using stakeholder images as exact assessments of brand performance compared with strategic vision, images held by stakeholders of who the university is and what it stands for (e.g. personality and relevance comparisons) should become part of the strategic envisioning process. The linkage between strategic intent and brand image should be evident. The results of the pair-wise t-tests revealed that significant statistical differences (xvii) existed between stakeholders’ perceptions of the expected and actual experiences when using the NMMU brand. To assess the magnitude of a possible ‘gap’ between stakeholders’ expectations and actual experiences of the NMMU brand, mean score differences were converted into relative percentage ratings. The most significant findings on actual experiences (on which the level of satisfaction is based) of the NMMU brand are as follows: All relative rating scores were below 92.05%. These relative satisfaction percentages imply that respondents were not satisfied with the NMMU brand, because their expectations were not fully met. The highest rating percentage (92.05%) was obtained in respect of the statement regarding “The NMMU slogan (‘for tomorrow’) reflects the NMMU brand identity”. The lowest rating percentage (78.33%) was given to the statement “The NMMU brand exceeds expectations in terms of promises”. The second lowest rating percentage (79.67%) was found for the statement “The NMMU brand delivers on promises”. The principal recommendations emanating from this study are summarised in three groups of recommendations, namely: Recommendations pertaining to the strategic implications of the findings for the NMMU marketing communication strategists. Recommendations pertaining to the interpretation of secondary sources on brand literature, and Recommendations for future research.
