- Description: Doctors can experience difficulty in accessing medical information of new patients. One reason for this is that the management of medical records is mostly institution-centred. The lack of access to medical information may negatively affect patients in several ways. These include new medical tests that may need to be carried out at a cost to the patient and doctors prescribing drugs to which the patient is allergic. This research investigates how patients can play an active role in sharing their personal health records (PHRs) with doctors located in geographically separate areas. In order to achieve the goal of this research, existing literature concerning medical health records and standards was reviewed. A literature review of techniques that can be used to ensure privacy of health information was also undertaken. Interview studies were carried out with three medical practices in Port Elizabeth with the aim of contextualising the findings from the literature study. The Design Science Research methodology was used for this research. A Hybrid Model for Managing Personal Health Records in South Africa is proposed. This model allows patients to view their PHRs on their mobile phones and medical practitioners to manage the patients’ PHRs using a web-based application. The patients’ PHR information is stored both on a cloud server and on mobile devices hence the hybrid nature. Two prototypes were developed as a proof of concept; a mobile application for the patients and a web-based application for the medical practitioners. A field study was carried out with the NMMU health services department and 12 participants over a period of two weeks. The results of the field study were highly positive. The successful evaluation of the prototypes provides empirical evidence that the proposed model brings us closer to the realisation of ubiquitous access to PHRS in South Africa.

- Description: In the domain of strategic game playing, the use of statistical techniques such as the Upper Confidence for Trees (UCT) algorithm, has become the norm as they offer many benefits over classical algorithms. These benefits include requiring no game-specific strategic knowledge and time-scalable performance. UCT does not incorporate any strategic information specific to the game considered, but instead uses repeated sampling to effectively brute-force search through the game tree or search space. The lack of game-specific knowledge in UCT is thus both a benefit but also a strategic disadvantage. Pattern recognition techniques, specifically Neural Networks (NN), were identified as a means of addressing the lack of game-specific knowledge in UCT. Through a novel hybridisation technique which combines UCT and trained NNs for pruning, the UCTNN algorithm was derived. The NN component of UCT-NN was trained using a UCT self-play scheme to generate game-specific knowledge without the need to construct and manage game databases for training purposes. The UCT-NN algorithm is outlined for pruning in the game of Go-Moku as a candidate case-study for this research. The UCT-NN algorithm contained three major parameters which emerged from the UCT algorithm, the use of NNs and the pruning schemes considered. Suitable methods for finding candidate values for these three parameters were outlined and applied to the game of Go-Moku on a 5 by 5 board. An empirical investigation of the playing performance of UCT-NN was conducted in comparison to UCT through three benchmarks. The benchmarks comprise a common randomly moving opponent, a common UCTmax player which is given a large amount of playing time, and a pair-wise tournament between UCT-NN and UCT. The results of the performance evaluation for 5 by 5 Go-Moku were promising, which prompted an evaluation of a larger 9 by 9 Go-Moku board. The results of both evaluations indicate that the time allocated to the UCT-NN algorithm directly affects its performance when compared to UCT. The UCT-NN algorithm generally performs better than UCT in games with very limited time-constraints in all benchmarks considered except when playing against a randomly moving player in 9 by 9 Go-Moku. In real-time and near-real-time Go-Moku games, UCT-NN provides statistically significant improvements compared to UCT. The findings of this research contribute to the realisation of applying game-specific knowledge to the UCT algorithm.

- Description: The purpose of this study was to investigate the use of mobile phones in organizing ad-hoc vehicle ridesharing based on hitch-hiking trips involving private car drivers and commuters in South Africa. A study was conducted to learn how hitch-hiking trips are arranged in the urban and rural areas of the Eastern Cape. This involved carrying out interviews with hitch-hikers and participating in several trips. The study results provided the design specifications for a Dynamic Ridesharing System (DRS) tailor-made to the hitch-hiking culture of this context. The design of the DRS considered the delivery of the ad-hoc ridesharing service to the anticipated mobile phones owned by people who use hitch-hiking. The implementation of the system used the available open source solutions and guidelines under the Siyakhula Living Lab project, which promotes the use of Information and Communication Technology (ICT) in marginalized communities of South Africa. The developed prototype was tested in both the simulated and live environments, then followed by usability tests to establish the viability of the system. The results from the tests indicate an initial breakthrough in the process of modernizing the ad-hoc ridesharing of hitch-hiking which is used by a section of people in the urban and rural areas of South Africa.

- Description: There is a slow adoption and use of electronic commerce or e-Commerce by Small, Medium and Micro-sized Enterprises based in the hospitality sector (hospitality SMMEs). Only a few hospitality SMMEs that have adopted e-Commerce show the migration of value adding activities to their e-Commerce platforms. As such, this study developed and proposed a model that shows how hospitality SMMEs in the Eastern Cape Province can attain extended e-Commerce adoption and use. Extended e-Commerce platforms are characterised by the institutionalization of e-Commerce that includes Search Engine Marketing activities and/or listing services on intermediary websites, and engaging through social media websites. Tourism and hospitality customers’ information needs and buying behaviour were used to guide the requirements of extended e-Commerce platforms for hospitality businesses. The proposed model outlined factors determining extended e-Commerce adoption, extended e-Commerce characteristics and the anticipated e-Commerce adoption outcomes. The model was evaluated in the Eastern Cape using a multiple-case study methodology. The study’s use of a multiple-case study was applied within the interpretivist paradigm and four cases were considered. Triangulation through document analysis, interviews and observation was used for collecting data regarding factors determining the transition to extended e-Commerce adoption. A questionnaire was used for evaluating extended e-Commerce use. Within and cross-case analysis with the aid of coding was used for data analysis. Data collection and analysis validated the proposed model as a model that shows how hospitality SMMEs can attain extended e-Commerce adoption and use. The proposed model concedes that, successful adoption and use of e-Commerce by hospitality SMMEs would result in e-Commerce adoption outcomes namely online sales, reservations and customer service. These e-Commerce adoption outcomes are the criteria against which the level of extended e-Commerce adoption is measured.

- Description: This dissertation addresses the problem of a lack of a formal incident response capability in the South African National Research and Education Network (SA NREN). While investigating alternatives it was found that no clear method exists to solve this problem. Therefore, a second problem is identified: the lack of a definitive method for establishing a Computer Security Incident Response Team (CSIRT) or Computer Emergency Response Team (CERT) in general. Solving the second problem is important as we then have a means of knowing how to start when building a CSIRT. This will set the basis for addressing the initial problem, resulting in a prepared, improved and coordinated response to IT security incidents affecting the SANREN. To commence, the requirements for establishing a CSIRT are identified via a comprehensive literature review. These requirements are categorized into five areas, namely, the basic business requirements followed by the four Ps of the IT Infrastructure Library (ITIL). That is, People, Processes, Product and Partners, adapted to suit the CSIRT context. Through the use of argumentation, the relationships between the areas are uncovered and explored. Thereafter, a Design Science Research-based process is utilised to develop a generic model for establishing a CSIRT. The model is based on the interactions uncovered between the business requirements and the adapted four Ps. These are summarised through two views -- strategic and tactical -- together forming an holistic model for establishing a CSIRT. The model highlights the decisions required for the business requirements, services, team model and staff, policies and processes, tools and technologies, and partners of a CSIRT respectively. Finally, to address the primary objective, the generic model is applied to the SANREN environment. Thus, the second artefact is an instantiation, a specific model, which can be implemented to create a CSIRT for the SA NREN. To produce the specific model, insight into the nature of the SANREN environment was required. The status quo was revealed through the use of a survey and argumentative analysis of the results. The specific decisions in each area required to establish an SA NREN CSIRT are explored throughout the development of the model. The result is a comprehensive framework for implementing a CSIRT in the SA NREN, detailing the decisions required in each of the areas. This model additionally acts as a demonstration of the utility of the generic model. The implications of this research are twofold. Firstly, the generic model is useful as a basis for anyone wanting to establish a CSIRT. It helps to ensure that all factors are considered and that no important decisions are neglected, thereby enabling an holistic view. Secondly, the specific model for the SA NREN CSIRT serves as a foundation for implementing the CSIRT going forward. It accelerates the process by addressing the important considerations and highlighting the concerns that must be addressed while establishing the CSIRT.

- Description: Creativity and innovation are significant for the creation of a knowledge and productive base economy with its associated growth, sustainability and job creation. However it is noticed that students will need to employ the techniques on creativity and innovation in order to prepare themselves sufficiently to become business owners and entrepreneurs in this current global world where government jobs are difficult to come by. Therefore, the primary objective of this study is to determine creative and innovative techniques that will prepare final-year students to become entrepreneurs. A hard copy Word document questionnaire was considered an appropriate measurement method for this study. The targeted population of the study included entrepreneurial experts, business owners, teachers and lecturers of business management/studies in the Sisonke District of Kwazulu Natal Province. Thus, some 100 entrepreneur experts, owners of businesses, teachers and lecturers were identified as part of the sampling frame. A total number of 67 questionnaires were administered out of the 100 targeted– giving a response rate of 67%. The quantitative data were processed using Excel, leading to appropriate descriptive statistical analyses, including frequencies, means, medians and standard deviations. In order to obtain a better understanding of a model that will prepare final year students to become entrepreneurs, problem statements and sub-problems were stated and a t-test was used to establish demographic variables, whilst correlation analysis among skills was conducted regarding the model of creative and innovative techniques. Factor analysis was conducted using the Cronbach’s alpha coefficient which confirms that training in the model will prepare students to become entrepreneurs. The results from the empirical study revealed that a model of creative and innovative techniques will prepare students to become entrepreneurs, with a total of 70% of respondents attesting to it. Based on the relevant literature study and the empirical results, recommendations were made in order to support the training needs of students on creativity and innovation techniques. However, the unavailability of an exhaustive entrepreneurial experts database and small number of further education and training colleges in the Sisonke District, did not allow the research to draw on a larger representative sample. Thus, this limitation has impeded in-depth statistical analysis that would have allowed the research to obtain more accurate findings. Further studies could be investigated from lecturers, business owners and experts whether an introduction of a special curriculum on creativity and innovation in further education and training schools may prepare students to become entrepreneurs.

- Description: Many Information and Communication Technologies for Development (ICTD) projects are established with the overall aim of positively developing the communities they are implemented in. However, the solutions that are provided are often commonly developed without the needs of these communities being sufficiently investigated beforehand. As a result the ICTD strategy of the project ends up not well aligned with the aims and targets of the needs of the community. As a result of this, an appropriate programme theory for the project and relevant impact indicators fail to be adequately developed. Consequently, when an impact assessment is conducted it is often found that the intended effects are not directly linked to the needs of the community or what the community had hoped to gain from the ICTD initiative. The purpose of this research serves to develop a needs-ICTD strategy alignment foundation that supports the identification and formulation of impact assessment indicators. Through this research, a framework is developed to support the alignment of ICTD strategy, the development and the promotion of contextual needs of rural communities and other frequently marginalized areas. The Needs-ICTD strategy alignment framework is composed of eight main components that describe the process that can be used to align ICTD strategy with community needs. These components include: collaboration between the internal and external stakeholders, the development of the community, conducting baseline studies, the needs assessment, the ICTD strategy, linking of the needs-ICTD strategy, and lastly the identification of impact indicators. An interpretive research approach is used to explore and inform the framework through a multi-case study investigation of the Siyakhula Living Lab and two projects in the Systems Application Products (SAP) Living Lab. Two main case study questions drive the exploration of the framework, that being: 1) How are the needs of the community elicited and how is the ICTD strategy aligned to the needs of the community? 2) And, why were the selected approaches chosen for aligning the needs of the community and ICTD strategy? Data for this research was collected qualitatively through interviews, document analysis and participant observation. Key findings indicate that the involvement of internal (local) stakeholders in the development and alignment of ICTD strategy to the needs of the community is still lacking. As a consequence, many community members end up not fully understanding the project objectives and how these objectives aims are to be achieved. The research also finds that ‘solution specific’ projects also fail communities as they focus specifically on one target group and repeatedly fail to assist the community holistically in supporting their information and their community development needs.

- Description: This project asserts that revolution is characterised by the expression of unthinkable possibilities, and so addresses the paradox implicit in any attempt to "write revolution." That is, how does one represent revolution without reducing it to an ordered term of reference, and thereby subduing its radical character? Additionally, can transformative action be conceptualised as a creative project to which an ethical subject may, and in fact should, be drawn? To answer these questions, my investigation develops in three strands. I combine the radical theory of Alain Badiou with similar affirmations of revolutionary intervention from Slavoj Žižek and Paulo Freire, and so create an aesthetic that affirms revolutionaries as agents of supplementary creativity. My first purpose is thus to establish revolution as a productive enterprise that enables peace, rather than a destructive undertaking that introduces violence. This done, I apply the resultant conceptual tools to literary representations of radical transformation, and demonstrate that my aesthetic enables new readings of the literature of revolution to which it is applied. In the course of my analysis, I also evaluate the suitability of Badiou's ethic as a standpoint from which to engage with literature on revolution. Ultimately, then, the aesthetic I construct not only contests the notion that radical transformation is always destructive, but also renders one sensitive to revolutionary literature's excessive and supplementary dimensions.

- Description: Maternal HIV-disclosure to an adolescent is a controversial issue especially when considering the suitable time and context in which disclosure should take place. Furthermore there have been other considerations such as the adolescent’s emotional maturity as well as gender issues which have played a role in regards to determining whether the adolescent would be able to understand and cope effectively post-disclosure. These considerations formed the basis of this study’s aim and objectives which primarily focused on taking into account the developmental aspects apparent in the adolescent phase. These include adolescent’s relations with their mother, their peers and the meaning attached to having an education and career in their lives. For purposes of this study it was deemed important to actually explore with the adolescent’s the meaning they uphold pertaining to maternal HIVdisclosure. This differs from previous research which has focused predominantly on accessing adolescent’s experiences via their parents and in particular, their mothers. Data of only three participants was included following in-depth interviews being conducted. Data was analysed via Interpretive Phenomenological Analysis (IPA) which enabled an enhanced understanding and meaningful interpretation of the adolescent’s experiences following maternal HIV-disclosure. From the findings it became apparent that most concerns had already been addressed and were similar when compared to previous research that had been conducted. However one notable different finding was that instead of adolescent’s acting in ways that would lead to them self-sabotaging their lives they instead portrayed themselves to be living in a responsible manner. It became apparent rather that it was the adolescent’s mother rather that became more inclined to engage in self-sabotaging behaviours.

- Description: Social networking sites are a recent phenomenon and have experienced tremendous growth in popularity especially among young people. Social networking sites are changing the way individuals communicate with each other and the world. Social networking sites (SNS) provide users with a unique computer-mediated environment where individuals are able to disclose their thoughts, feelings, and experiences within their own social network. The present study aims to explore the experiences of young adults regarding Facebook. A transcendental phenomenological approach was used to elicit the essence of the experiences of the participants. Theoretical sampling ensured relevant participants were selected through haphazard sampling procedures. Data was collected through the use of biographical questionnaires and individual, semi-structured interviews. The data was processed according to the four phenomenological principles epoche, phenomenological reduction, imaginative variation and synthesis using Tesch’s eight steps. Lincoln and Guba’s model was used to assess the trustworthiness of the data obtained. The participants described their experiences of Facebook by highlighting how they use Facebook as a communication tool which assists them in their relationship maintenance with others. Participants use self-presentation on Facebook to manage how they are perceived. The participants experience Facebook as having many privacy risks. They indicated that Facebook has addictive qualities and facilitates cyber stalking behaviour.

- Description: Estuaries worldwide are being subjected to various degrees of catchment degradation, which is having severe consequences on the integrity of these aquatic ecosystems and their ability to function properly. This thesis investigated the relationship between catchment land-cover and estuarine health in four temporarily open/closed estuarine systems (TOCEs) in South Africa, namely the Groot Brak, East Kleinemonde, Mdloti and Tongati. GIS techniques were employed to delineate catchments, lower sections of catchments, 1 km and 100 m buffer zones, and to quantify the extent of land-cover classes present within these delineations. Anthropogenic activities outlined by the Department of Water Affairs and Forestry (DWAF) Resource Directed Measures (RDM) studies and their associated land-cover classes were described. The possible links between catchment and buffer zone land-cover class composition and health of the estuaries were explored. Results indicated that there was a relationship between catchment and estuarine health within the Coastal Protection Zone (CPZ) (1 km and 100 m) buffers, but not at a broader catchment level. Out of natural, urban built-up and cultivation land-cover classes, natural land was determined to be the best predictor of estuarine health within the CPZs. A method of rapidly assessing South African TOCE condition was applied and could be used to prioritise these estuaries for rehabilitation and/or conservation.

- Description: Psychobiographical researchers methodically formulate life histories and interpret them by means of psychological theories. The research typically focuses on exemplary and completed lives. The cases that are studied are usually of individuals who are of particular interest to society as a result of excelling in their particular fields, be they to society’s benefit or detriment. Antwone Fisher was chosen for this study using purposive sampling as he meets the psychobiographical requirement of being an extraordinary individual. Fisher grew up in the Foster Care System and faced many abusive experiences as child. Despite difficult beginnings, Fisher developed into a stable and creative adult who excels as a poet, screenwriter and film director. The primary aim of this study is to describe and interpret the life of Antwone Fisher through Erikson’s theory of psychosocial development. The data was processed and analysed using Miles and Hubermans’ general view of qualitative analyses as well as Alexander’s method of asking the data questions. This study contributes to the development of psychobiographical research in South Africa as well as to personality and developmental theory.

- Description: Dr. Christiaan Neethling Barnard (Barnard) was a world renowned surgeon who made medical history when he performed the world’s first human heart transplant. Barnard was celebrated by some for his courage and contribution in advancing the field of cardiothoracic surgery, while others believed that the technique of human heart transplantation was not his own. Barnard became known for his controversial lifestyle, and acquired a reputation as a playboy. He died in 2001 at the age of 78, following an asthma attack. The aim of the current study was to explore and describe the personality development of Barnard, by applying Alfred Adler’s theory of Individual Psychology to the context of his lived life. The study used a single case study research design, and purposive sampling was used to select the subject. This selection was made on the basis of the researcher’s interest in Barnard’s life history and his immense contribution to medical science. Data sampled was qualitative, and was collected from primary and secondary data sources. Collected data was analysed in accordance with Alexander’s model of data analysis. The findings of the study indicated that Barnard’s life was in many respects aligned with Adler’s theory and that his striving for significance was largely influenced by his social environment as well as the cultural context in which he lived.

- Description: This study is a psychobiographical study, aiming to explore and describe the life of John Henry Newman (1801-1890), a theologian, priest, and cardinal of the Roman Catholic Church, through the application of Erik Erikson’s theory of Psychosocial Development. Newman is a significant figure in the English-speaking Christian world and his life and thought remains of interest and importance, particularly in the fields of philosophy, theology, ecclesiology and education. Newman was beatified in 2010 and therefore this study also considers the hagiographical nature of biographical data. This study utilises a qualitative single case study approach and the subject was selected through purposive sampling based on interest value. Data were collected from primary and secondary sources to enhance validity. The data were analysed by organising and reducing information obtained regarding Newman’s life and then displaying it for discussion. The study considers Newman’s life, reconstructed from birth, through adolescence and adulthood to his death and also considers his posthumous legacy. The main themes of discussion revolve around Newman’s development of his religious identity and his life as a churchman and an academic. It considers how a psychosocially functional individual such as Newman manifests certain dystonic, maladaptive or malignant tendencies such as doubt, shame, guilt and overextension, and how these impact the formation of religious identity and the experience of God and the spiritual life. Basic trust, celibate intimacy and generativity emerged as three significant areas of importance in the Newman’s life and identity. The study highlighted the value of psychobiographical studies and of Erikson’s theory in understanding development. Recommendations for future research in this field are made in the hope of further uncovering and understanding personality, religious identity and psychosocial development.

- Description: The study consists of a psychobiography of the American entrepreneur and innovative co-founder of Apple Computers, Steven Paul Jobs (1955 – 2011). The psychobiographical research method qualitatively considers the lived life of an individual in an attempt to understand the psychological development in the context of applied psychological theory. A theoretical integration of Adler‘s Individual Psychology and Antonovsky‘s Sense of Coherence was utilized in the present study. This integrative approach facilitated a dynamic and holistic picture of the individual‘s functioning in illuminating not only personality but also the individual‘s social context, choice making capacity, general resistance resources and the individual‘s ‗meaning making‘ capacity in the strive towards health and superiority. Steven Paul Jobs revolutionised personal computing. Ranked as Forbes‘ seventeenth most powerful person and Man of the Year by The Financial Times in 2010, Jobs‘ contribution to modern technology is widely acknowledged and revered. To ensure the accurate description of the lived life of Steven Paul Jobs, extensive data was examined by utilizing Alexander‘s model of identifying salient themes. The study considered the nature and methodology of psychobiography, the theories of Alfred Adler and Aaron Antonovsky and the life of Steven Paul Jobs that resulted in an integrated psychological description of the subject. The findings of this study indicate that Steven Paul Jobs‘ unique context (environment and constitutional attributes) was valuable in light of the theoretical frameworks that the present study is grounded upon as it illustrated an individual‘s self-determination and capacity to exercise choice in response to life challenges. The study highlighted that the individual is not necessarily a passive bystander to his life events but rather is driven by an internal forward striving. Key concepts: Aaron Antonovsky, Alfred Adler, Apple Computers, Individual Psychology, Psychobiography, Sense of Coherence, Steven Paul Jobs.

- Description: Helen Martins devoted approximately the last thirty years of her life to converting her family home into a unique fantasy world which she named the Owl House. Since her death in 1976 the Owl House has become a national monument and museum in South Africa. Throughout her life Helen was considered by most of the surrounding villagers to have been strange, and she withdrew increasingly from society. However, she appeared to have contained a desire for human connection. There are several instances in which she expressed this desire, such as through the numerous letters which she wrote to fellow artists. The existing body of literature on Helen illustrates the complex nature of her personality; however the question of which personality style she best typifies has remained unanswered. In order to answer this question a psychobiography was conducted on Helen. Psychobiographies entail a biographical representation of a person's life history to which a psychological theory is applied. The psychological theory utilised within the current study was Millon's (1969/1996) Biosocial- Learning Theory. Thus, the chief objective of this study was to describe and interpret Helen's personality style through the use of Millon's (1969/1996) Biosocial-Learning Theory. Alexander's model of data extraction and Miles and Huberman's three step approach were implemented in order to reduce, organise and analyse the data. The findings of this study reflected that Helen deteriorated from one of Millon's (1969/1996) proposed personality styles to another as she aged. The current findings may illuminate Helen's motives for obsessively devoting her life to the creation of her fantasy world.

- Description: Worldwide the population in cities is increasing. It is the responsibility of local government to provide public safety services in order to ensure the safety of their citizens and, yet, the local government often have inadequate resources to do this. ‘Smart Cities’ is a new and innovative concept that has emerged during the past few years and which involves using current infrastructure and resources more effectively and efficiently. One of the methods used to collect data in a smart city is participatory crowdsourcing but, in order to ensure effectiveness and efficiency, it is essential that a large amount of data be collected from the participants in such a project, who are generally citizens residing in the city. This study was conducted in the city of East London, which is part of the Buffalo City Metropolitan Municipality (BCMM). The study made use of a Design Science approach with a mixed method data collection method. The quantitative data collection comprised a questionnaire that was completed by 394 participants, while the qualitative data collection included a detailed literature review, conversational analysis and observations arising from the building of the crowdsourcing system prototype. The design artefact produced by this research is a model based on the literature, conversational analysis and the principles and concepts learnt from the prototype. Thus, this model represents what must be incorporated in the prototype to assist with the implementation of a public safety, participatory crowdsourcing smart city in a developing country. The model includes three areas ‒ the crowdsourcing system, the city (Buffalo City Metropolitan Municipality) and the citizens of East London. The crowdsourcing system incorporates factors of information security, specifically the CIA triad, and the usability of the crowdsourcing system. Usability includes characteristics such as the quality of the system and interface, as well as the usefulness of the public safety, participatory crowdsourcing system which was used to measure the confidence of the East London citizens in the system. Three steps were identified in the literature as being necessary for the implementation of a smart city project by a city. These steps include the planning, development and delivery of the smart city project. Finally, the trustworthiness of the public safety participatory crowdsourcing system is determined by the ability, reliability and benevolence of the system. These three characteristics were included in the citizen factor of the model.

- Description: Developing countries are embracing Information Communication Technologies (ICTs) as a tool for alleviating poverty. There are, however, still challenges that developing countries face in trying to establish Information Communication Technology for Development (ICT4D). Among the major challenges is the lack of proper resource management which results in poor sustainability of ICT4D initiatives. If these ICT4D initiatives are to be sustainable for the benefit of current and future generations, proper resource management methods are to be developed and applied. This study proposes a resource management framework that can be applied to the management of ICT4D resources with the aim of achieving sustainability. The framework is informed by theory, and validated through enquiry in the field. Qualitative research methodology was used as a research approach for this study where three rural ICT4D initiatives were used as case studies. The case studies were conducted in rural Zimbabwe to investigate how proper resource management can influence the sustainability of ICT4D initiatives. It was identified from the study that the lack of proper resource management methods adversely affects the initiatives’ sustainability. The proposed resource management framework will guide ICT4D resource management to enhance the initiatives’ sustainability.

- Description: A review of Archean granite-greenstone terranes, orogenic gold deposits, the Slave Province and modern exploration tools, techniques and methods was conducted to identify prospective areas in the Yellowknife domain for hosting orogenic gold deposits and illustrate the best exploration methods for delineating this deposit type. This study identifies Archean granite-greenstone terranes as economically important hosts to quartz-carbonate vein-hosted orogenic gold deposits. These deposits occur at convergent plate margins, but can also be related to local extensional tectonics within a convergent setting. Heat generated from tectonic processes can trigger hydrothermal fluid movement along first-order faults and shear zones. Precipitation of gold-bearing quartz-carbonate veins from the hydrothermal fluids occurs in second- and third-order faults and shear zones related to the first-order structures. This study also identifies the Archean Slave Province in northern Canada as a well-endowed craton with numerous orogenic gold deposits, diamondiferous kimberlites, VMS deposits and several other mineralization styles. In particular, three greenstone belts (Yellowknife, Cameron River and Beaulieu River) associated with likely first-order structures are comprised of prospective rocks for hosting orogenic gold and VMS mineralization. The Yellowknife greenstone belt hosts the past-producing and former world-class Con and Giant orogenic gold deposits, but has been little explored with modern exploration techniques. The Cameron River and Beaulieu River greenstone belts host numerous base and precious metal VMS and BIF-hosted orogenic gold prospects and deposits, indicating mineralization is present. There is considerable potential for significant discoveries to be made using modern exploration techniques in the greenstone belts; however, exploration in the region has been hindered over the past decade by ongoing political negotiations. Once the political negotiations are finalized, application of modern exploration methods and techniques in the prospective greenstone belts should be carried out. Regional scale methodologies should be applied to generate targets using predictive modelling, implicit 3D modelling, 3D geochemistry and exploration targeting so decisions defining a businesses strategy for ground acquisition of high priority targets are made using quantitative analysis. Once ground is acquired, field-based exploration for orogenic gold and VMS deposits should include geological mapping with a focus on structural geology, geochemical sampling and airborne magnetic, radiometric and EM geophysical surveys. Prior to reconnaissance drilling, integration of all data layers and interpretation within a common 3D earth model should be conducted. Following successful reconnaissance drilling, definition drilling along strike and down dip of intersected mineralization, combined with borehole geophysics, should be carried out to delineate the extent of mineralization.

- Description: Waste is not only harmful to the environment alone but it is also a threat to human health and as such its proper management becomes critical. This study which adopted a qualitative approach focused on the review of policies for sustainable solid waste management service in Buffalo City Metropolitan Municipality in an effort to seek what the municipality’s Solid Waste Department should consider in ensuring that all the communities live in a litter free, clean and healthy environment, and ensure that such a service is received by all communities within its jurisdiction. The most sustainable solid waste management strategy would be to adopt the solid waste hierarchy of promoting waste minimisation, re-use, recycling, waste treatment and disposal as the last resort.
