- 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.

- Description: ollective bargaining continues to play a prominent role in shaping employment relations in South Africa, without which the individual worker is powerless and in a weaker bargaining position against his employer. Collective bargaining can be described as an interactive process that resolves disputes between the employer and employee. In South Africa the advent of democracy was accompanied by numerous interventions to level the historically uneven bargaining field. Therefore in examining the history of collective bargaining in South Africa it is necessary to reflect on the state of labour relations prior and post the 1994 democratic elections. The study provides an overview of the practices and processes of public service collective bargaining in the old and new public service. The public sector accounts for a very significant proportion of employment in all countries around the globe, South Africa is no exception. Although the state as employer is in a stronger position than its private sector counterpart, the public employee is potentially also in a stronger position than its private sector counterpart. A defining characteristic of most government activity and services is that they are the ones available to the public. This means that industrial action which disrupts such services has a very significant impact on the public, serving as a substantial leverage in collective bargaining. The bargaining councils in the public sector which ensure the effectiveness of collective bargaining are maintained, are examined to provide a comprehensive understanding of the workings of these institutions. Some of the gains and challenges are also explored to provide a holistic picture of state of collective bargaining in public service. A comparison of countries seeks to analyse and compare globally the developments of collective bargaining in public administrations. The different political systems around the world have developed various labour relations processes in the public service, an examination of the approaches and mechanisms provides alternative ways of doing things. Recommendations are made regarding the changes that need to be made, as well as matters, which need to be analysed and examined further.

- Description: Poverty, inequality and unemployment have always been challenging first in South Africa with special reference to rural South Africa. These persistent challenges with severe impacts on black population are believed to be the results of the previous governance in South Africa. Policies have been formulated, reformulated and others implemented in a form of development projects which have achieved little success in pursuit of combating these challenges. However, in the process of achieving rural development through developmental projects, a fundamental stage in the life cycle of these projects is often omitted or given little attention. This stage is the monitoring and evaluation stage which is critical to ascertain potential impacts (both positive and negative) especially if the project is to be replicated and achieve its objectives as postulated in the millennium development goals. This thesis attempted to carry out a Socio-Economic Impact Assessment (SEIA) of the Agripark project implemented at Dutywa on the livelihoods of communities directly affected by this project. The Agripark project is a project that comprises three linked components, a seedling nursery, an agro-processing facility and a sizeable feeder plot and has been implemented to benefit four villages. This project has been implemented as the second Agripark project by the University of Fort Hare in partnership with the province’s Department of Agriculture. To track change after the implementation of the project, data were collected from the same respondents that were interviewed for the baseline study, therefore, the same sample size that was used in the baseline study was also used for this study. As a tool for data collection, a questionnaire was developed to elicit the required information and was interviewer administered during data collection. The results of the study revealed that Agripark project has impact on both social and economic wellbeing of the households. The processing unit of the project was not yet functioning therefore the project was not fully effective thus the impact was not as intended by the project when the study was carried out. Skills transferred were only on production but only a small number of people could receive them. These households largely relied on external sources of income mainly on social grants and their contribution to total household income had increased to 88% in 2011 compared to 80% in 2008. As much as the increase in incomes cannot be entirely be because of the project but Agripark had a positive impact on household incomes through wages of those employed there and through increased profitability of hawking vegetables. The proportion of household earning incomes less than the Poverty line fell from 85% in 2008 to approximately 79% in 2011. The household complemented their staples with a variety of vegetables and the main source of these vegetables was Agripark even though own production was declining. Even though food was still the main item of these households expenditure, the proportion of income spent on food fell from 64% in 2008 to 48% in 2011. There were no environmental impacts found. From the descriptive analysis, the project had impact on the livelihoods of these households because it brought change on the household expenditure as a result of the income earned by those who are working in the Agripark. There was an improvement on risk of food insecurity through cheaper vegetable that both physically and financially attainable. However, as much as the project had positive impact, there were also concerns raised by the respondents that the employment was only biased to certain individuals which cased stress to some households. Furthermore, the empirical analysis of the selected variables showed that participation in Agripark had an impact on economic wellbeing of the beneficiaries. Thus, funding must be made available to the project so that it can upgrade their electricity and have the processing plant running as it may be the major source of employment, skills development and achievement of its objectives.

- Description: The issues of capacity and capacity development in the response to HIV and AIDS is a topic of intense academic interest and is on the agenda of development practitioners, particularly as these issues are linked to community HIV and AIDS competence and sustainability of civil society organisations and community capacity. The capacity development model of the Southern African AIDS Trust is one of the more illuminating examples of capacity development of civil society organisations for the enhancement of community HIV and AIDS competence in southern Africa. The thesis examines the conceptualisation and implementation of the Southern African AIDS Trust's capacity development model in order to identify and understand the multi-dimensional factors that influence the success and sustainability of HIV and AIDS responses. It argues that, even though the conceptualisation, formulation and implementation of the model were appropriate and yielded acceptable benefits to communities in relation to HIV and AIDS, the sustainability of the model depended fundamentally on the availability of requisite resources. The dependence on external resources, the availability of which is in large part beyond the control of the Southern African AIDS Trust and its community-based beneficiaries, undercuts the sustainability of the model and the programmes delivered through it. Community capacities and community-based HIV and AIDS responses are sustainable only to the extent that communities have sufficient resources to build capacities and develop responses, or can leverage and negotiate external inputs. The degeneration of capacity in intermediary organisations (such as Southern African AIDS Trust) that support community competence undermines models that at first sight seem suitable for effective capacity enhancement with regard to HIV and AIDS programmes. In this regard, the thesis also focuses on the organisational crisis within Southern African AIDS Trust and the ramifications this had for community HIV and AIDS competence.

- Description: Foundation provisioning has a long history in South Africa, and is central to the transformation agenda, particularly the broadening of successful participation in higher education (HE). As access initiatives underpinned by various conceptualisations, foundation programmes evolved from peripheral, to semi-integrated and finally fully integrated curricular models in the form of current Extended Studies Programmes (ESPs). Underpinning the provision of Extended Studies is the acknowledgment that students who enter institutions are essentially ill equipped to cope with the demands of higher education studies, “leaving institutions themselves free of the responsibility of student failure” (Akoojee & Nkomo, 2007:391). This under-preparedness has been attributed to the ‘articulation gap’ between secondary and higher education, which in turn contributes to low retention and graduation rates (CHE, 2013:17). Situated within an overarching commitment to access and success, the Extended Studies Programme attempts to systematically address the ‘articulation gap’. This study evaluated the extent to which the Rhodes University Humanities Extended Studies Programme is achieving its objectives from a transformation perspective, specifically the broadening of successful participation in higher education. The majority of previous works on the evaluation of foundation programmes focused on measurable dimensions of student access and success – that is retention and graduation rates. This thesis considered both the measurable outcomes of the programme as well as the actual teaching and learning process. Given the shifts that have taken place in foundation provisioning, the evaluation of the current model of foundation provisioning necessitated their location in history. Therefore, the evaluation of the Rhodes University Humanities Extended Studies Programme was undertaken in view of the shifts, achievements, challenges and critics of its predecessor programmes. Specifically, the following dimensions were considered in the evaluation of the programme: i) assumptions underpinning the design and purpose of the programme, ii) teaching and learning practices in the programme, iii) student and staff perceptions of the programme, iv) students’ experiences of the programme, v) the validity of the programme in the broader institution, and vi) the measurable outcomes of the programme − that is retention and graduation rates of students enrolled in the programme. The triangulation of qualitative data collection techniques provided access into the different layers of institutional relations, processes and structures, which not only affect teaching and learning in the programme, but also determine students’ engagement with different academic and social aspects of the broader university. The theoretical insights of Pierre Bourdieu and Amartya Sen were integrated in order to provide analytical tools for both understanding the causes of inequalities in higher education, and evaluating institutional processes and structures that perpetuate or transform inequalities. Whilst Bourdieu’s social reproduction thesis exposed the ways in which social structures shape educational processes and outcomes, Sen’s capability approach provided tools for evaluating both institutional arrangements and individual capabilities – that is, the freedom to achieve desired educational outcomes (Sen, 1992:48).

- Description: The perceptions of employees regarding electronic surveillance in the workplace were studied using a mixed method approach. The change that permeates society and organisations have not escaped public FET institutions in South Africa. These changes such as computerisation of work and the employment of electronic surveillance, have implications for management, control, privacy, productivity and trust in the workplace. Yet, public FET institutions are not performing to the expected standards. Surveillance of work and employees at these institutions are interventions of management to ensure organisational goals are achieved. Despite the prevalence of electronic surveillance in the workplace, employee perceptions and their lived experiences thereof are seldom reported. Published research barely focuses on employees’ perceptions of electronic surveillance in the workplace, and instead offers a perfunctory look at the perceptual dimensions. Employees’ perceptions reflects their lived experiences in the workplace and yield a foundational understanding of workplace dynamics and organisational behaviour. The perceptions of employees regarding electronic surveillance were viewed through the lens of quantitative and qualitative analysis to give statistical and thick descriptions respectively to augment better understanding. The study therefore provides a descriptive account of employees’ perceptions of electronic surveillance and its effects. Specifically the study examined employee perceptions of electronic surveillance as a control measure of management, as an intrusion of employee privacy and impacting on the trust relationship and productivity. An extensive review of the literature provided the basis for the research questions and eight hypotheses were proposed.

- Description: The perceptions of employees regarding electronic surveillance in the workplace were studied using a mixed method approach. The change that permeates society and organisations have not escaped public FET institutions in South Africa. These changes such as computerisation of work and the employment of electronic surveillance, have implications for management, control, privacy, productivity and trust in the workplace. Yet, public FET institutions are not performing to the expected standards. Surveillance of work and employees at these institutions are interventions of management to ensure organisational goals are achieved. Despite the prevalence of electronic surveillance in the workplace, employee perceptions and their lived experiences thereof are seldom reported. Published research barely focuses on employees’ perceptions of electronic surveillance in the workplace, and instead offers a perfunctory look at the perceptual dimensions. Employees’ perceptions reflects their lived experiences in the workplace and yield a foundational understanding of workplace dynamics and organisational behaviour. The perceptions of employees regarding electronic surveillance were viewed through the lens of quantitative and qualitative analysis to give statistical and thick descriptions respectively to augment better understanding. The study therefore provides a descriptive account of employees’ perceptions of electronic surveillance and its effects. Specifically the study examined employee perceptions of electronic surveillance as a control measure of management, as an intrusion of employee privacy and impacting on the trust relationship and productivity. An extensive review of the literature provided the basis for the research questions and eight hypotheses were proposed. A survey, by means of an electronic questionnaire, was conducted to test the hypotheses using a random sample of employees at three public FET institutions in the Eastern Cape Province, South Africa. The results are presented followed by a discussion, conclusions and limitations. Suggestions and recommendations for future research are also indicated. The central thesis of the study is presented, namely that electronic surveillance is experienced as a measure of management to control workers and that privacy as well trust, as an element of the employment relationship, are influenced by it. Further findings indicated that there are no statistically significant differences in the responses of the three job categories namely lecturers, managers and administration and support staff.

- Description: Parasitic diseases remain a health burden affecting more than 500 million people worldwide with malaria having the highest mortality rate. The parasites can be transferred to the human bodies either through the mouth by ingestion of contaminated food and water or through the skin by bug bites or direct contact to environments harbouring them. Epidemiological control seems to be impossible since there is failure to control the insect vectors as well as practice of hygiene. Therefore, this has led to the development of a number of vaccines, chemotherapy and disease control programs. However, parasites have increasingly developed resistance to traditionally used anti-parasitic drugs and due to that fact there is need for alternative medication for parasitic diseases. Heat shock protein 90 (Hsp90) facilitates the folding of proteins in all living cells and their role is more important to parasites because of their environmental changes, from vector to host. Hsp90s play a major role; therefore this justifies the need for a deeper analysis of the parasitic Hsp90s. Recent studies have revealed that, the Plasmodium sp. Hsp90 has an extended linker region which increases the protein’s affinity for ATP and its inhibitors. Therefore we hypothesize that there are also significant features in other parasitic Hsp90s which would lead to Hsp90 being defined as potential drug targets. In the present study an attempt was made to gain more insight into the differences in primary structure of human and parasitic Hsp90s. The sequences were retrieved from the NCBI database and analysis was done in three groups basing on the localization of the Hsp90. The physicochemical properties were calculated and in every group, the protozoan Hsp90s showed significant differences when compared to the human orthologs. Multiple sequence alignments (MSA) showed that endoplasmic reticulum Hsp90s have an extended region in the middle domain indicating their ability to bind to a unique subset of client proteins. Sequence identities between the human and parasites showed that the protozoan Hsp90s are less related to the human Hsp90s as compared to the other parasites. Likewise, motif analysis showed the trypanosomatids and apicomplexan groups have their own unique set of motifs and they were grouped together in the phylogenetic analysis. Phylogenetic analysis also showed that, the protozoan Hsp90s forms their own clades in each group while the helminths did not form in endoplasmic reticulum group. In this study, we concluded that, Hsp90 can be a potential drug target for the protozoan species and more specifically those from the apicomplexan and trypanosomatids groups.

- Description: This research is an investigation of the relationship between employees 'happiness' and the financial performance of a financial services organisation in South Africa. As a component of the financial services industry the banking sector contributes greatly to the economic growth of the country. The South African Banking sector is concentrated and highly competitive. It is vital for banks to maintain competitiveness and ever increasing global competition adds further pressure on organisations to financially perform so as to meet the demands of their shareholders. The literature that has been reviewed and previous research suggest that employee 'happiness' is a vital variable influencing the performance and success of individuals. Organisational performance will be measured in terms of financial performance for the purposes of this research. The concept of financial performance and 'happiness' are discussed and a questionnaire based on the Satisfaction With Life Scale (Diener et al,1985) is used to determine the levels of 'happiness' at selected branches within the institution. The individual branches financial performance is determined via calculating selected ratios, namely cumulative leverage, cost to income ratio and net yield. An analysis of correlation was conducted to establish whether or not a relationship of statistical significance exists between employee 'happiness' and financial performance. It was concluded that there is no relationship of statistical significance between employee 'happiness' and the financial performance of branches within the organisation, it was suggested that other factors exert a much greater influence over financial performance. Some of these factors influencing financial performance are discussed and recommendations for further research are made.

- Description: The challenge of having to create and remember a secure password for each user account has become a problem for many computer users and can lead to bad password management practices. Simpler and less secure passwords are often selected and are regularly reused across multiple user accounts. Computer users within corporations and institutions are subject to password policies, policies which require users to create passwords of a specified length and composition and change passwords regularly. These policies often prevent users from reusing previous selected passwords. Security vendors and professionals have sought to improve or even replace password authentication. Technologies such as multi-factor authentication and single sign-on have been developed to complement or even replace password authentication. The objective of the study was to investigate the password habits of South African computer and internet users. The aim was to assess their attitudes toward password security, to determine whether password policies a↵ect the manner in which they manage their passwords and to investigate their exposure to alternate authentication technologies. The results from the online survey demonstrated that password practices of the participants across their professional and personal contexts were generally insecure. Participants often used shorter, simpler and ultimately less secure passwords. Participants would try to memorise all of their passwords or reuse the same password on most of their accounts. Many participants had not received any security awareness training, and additional security technologies (such as multi-factor authentication or password managers) were seldom used or provided to them. The password policies encountered by the participants in their organisations did little towards encouraging the users to apply more secure password practices. Users lack the knowledge and understanding about password security as they had received little or no training pertaining to it.

- Description: The equivalence principle has proven to be central to theories of gravity, with General Relativity being the simplest and most elegant theory to embody the principle. Most alternative theories of gravity struggle to satisfy the principle and still be distinct from GR. Extensions of cosmological and quantum theories question the irrefutably of the equivalence at every scale. The possibility of an equivalence principle violation at galactic scales would be an exciting prospect. In this thesis, we will carefully examine the equivalence principle through the study of chameleon scalar-tensor theories, this will include solutions for hypothetical stars known as boson stars. Such theories find varied application, especially in cosmology, where they model dark energy and inflation. The AWE hypothesis, is an instance of this. It is a nonuniversally coupled model in which violations of the equivalence principle on galactic scales may be apparent. We investigate spherically symmetric and static solutions within the framework of this theory. The constraints obtained from galactic rotation curves results in values of the couplings that show no significant violation of the equivalence principle or values consistent with a theory of dark energy
