- Description: No cognitive study has implemented an exercise modality that requires both physical effort and cognitive control, therefore, the effects of such exercise are unknown. Additionally, no studies have investigated how prolonged batting impacts cognitive functioning nor how physical responses and cognitive functioning are related while batting. At intensities of 6070 percent heart rate maximum, acute and prolonged bouts of physical activity have been shown to improve cognitive functioning. At higher intensities, the beneficial effects are minimal and in some cases performance is impaired. Therefore, the aim of this investigation was to determine how prolonged intermittent batting (a task that requires high muscular and cardiovascular loads but also continuous cognitive control) affects cognitive, physiological, physical and biophysical responses in amateur batters. Further aims included to test the reliability of the method employed in assessing these responses. To answer this question, the investigation was separated into three studies: phase 1 (a large-scale pilot) and phase 2 and 3 (a repeated measures test-retest hypothesis). In each phase, batters completed the 30 over BATEX simulation, which replicated the demands of scoring a one-day international century. To establish physiological, physical and perceptual strain; heart rate, sprint times and perceived exertion data were collected each over. Changes in body mass over time were compared to determine the effects of fluid loss on cognitive performance. Before, during and after the simulation, psychomotor function, visual attention, working memory, visual learning and memory as well as executive functions were assessed (CogState brief test battery). During cognitive assessments, heart rate and heart rate variability parameters were sampled so that autonomic modulation of the heart could be determined. The methodological differences between phase 1 and phase 2 and 3, were (respectively); the frequency of cognitive assessments (five vs. three), the samples used (15 schoolboy vs. 16 academy batters), hydration protocols (250ml of Energade vs. water ad libitum) and a singular change in a physical dependent variable (batting accuracy vs. vertical jump). In schoolboy and academy batters, the prolonged batting simulation placed significant strain on the cardiovascular and muscular subsystems; increasing heart rate (p<0.01), decreasing body mass (p<0.01) and deteriorating sprint performance (p<0.01) over time. In each sample, batters’ perceived exertion increased significantly (p<0.01) and exertion was highest in the final over of the protocol. Interestingly, the changes in cardiovascular and muscular responses were larger in schoolboy batters. While the cognitive performance decrements over time were not significant in academy batters (p>0.05; d<0.2), the magnitude of impairment in psychomotor function (p>0.05; d = 0.37), visual attention (p>0.05; d = 0.56), working memory (p>0.05; d = 0.61) and executive function (p>0.05; d = 0.58) was larger in schoolboy batters. In both samples, the simulation altered the modulation of heart rate significantly. Heart rate variability decreased linearly with time spent batting (p<0.01; d>0.8). During cognitive assessments, heart rate variability increased with time-on-task, where responses were significantly higher (p<0.05) in the last task of the battery compared to the first. Importantly, the results of the retest phase were the same as in the test phase and only two condition effects were observed; (i) heart rate (retest lower: p<0.04;d = 0.39), (ii) body mass (retest lower: p<0.03;d = 0.09). A task-related condition effect in heart rate variability (PNN30) was also observed (retest higher: p<0.03; d = not calculated). Resultantly, the test-retest reliability of phase 2 and 3 was high. The results indicate that prolonged intermittent batting at an intensity of 64-77 %HRmax impaired cognitive functioning in amateur batters. However, the cardiovascular and muscular strain induced by prolonged intermittent batting and its effects on cognitive functioning are mediated by intrinsic and extrinsic factors (age, training status, playing experience and hydration). Therefore, while prolonged batting has similar effects on cognitive functioning as acute bouts of physical activity, they do not share the same relationship. The author hypothesises that the continuous cognitive component inherent in prolonged batting mitigates the beneficial effects of physical activity, as demonstrated previously. Future research is needed to elucidate this relationship. Additionally, player experience affects the way in which batters regulate performance while batting; which also affects the rate of and magnitude of impairment during batting. Finally, the methodological limitations of this study provide direction for future research into batting.

- Description: The transference of knowledge and the creation of a knowledge vault within operations of the Hospitality sector is the cornerstone to the success of this dynamic contributor to the economy, not only as a skills developer, but also as a collective group of experts that unknowingly build a community of expertise that transfer knowledge amongst themselves within an organisation. Leadership that share knowledge, whether tacit or implied, leads to the development and knowledge growth from members to those who are exposed to the intricacies of decision making and business practices. This leads then to the skills development and retention of the participants who feel nurtured and fulfilled in the employment within the organisation and view themselves as valued members. The finding of this research reveals a correlation between knowledge sharing and the desire for job security that leads to the feeling of being nurtured and finding the employment positive and enjoyable. The transference of knowledge allows the receiver of the knowledge to develop to where the point of the receiver becoming an expert in their chosen field is attained and the collective of the mangers are developed to the level of a community of experts in their various fields. However the academic qualifications of leadership is low, the significance of this highlights the level of networking amongst themselves as paramount to the success of this multi million rand industry.

- Description: Extreme flood events have been found to occur in the Eastern Cape Province of South Africa. The southern and south-eastern coastal regions are particularly susceptible to floods with daily rainfall records of up to 490 mm having been recorded here. In order to gain a better understanding of these floods, historical floods in the southern parts of the Eastern Cape have been analysed in this study. This study aimed to investigate the most extreme flood events in the history of the area and to analyse the surface observational data during the heavy rainfall events found, to contribute to the understanding of these heavy rainfall events. Seven case studies were investigated using NCEP/NCAR Reanalysis 1 data and surface observational data, to analysis the synoptic circulation and surface data tendencies during heavy rainfall events. All of the case studies that had synoptic data available showed to have a COL system present with the upper air low lying westward of the flood area. The surface synoptic situation presented an intense high pressure system lying south west or south of the country in the Atlantic Ocean between 35-45°S. Another key factor was a surface trough over the interior of the country, due to the COL, extending southwards to protrude off of the south or south eastern coastline east of the flood areas. The combination of these three systems colloquially referred to as a “Black South-Easter”, produced dangerous rainfall intensities when the winds were perpendicular to the coast. The results of the surface observations revealed temperatures increasing at night (against diurnal cycles) with increasing relative humidity preceding the heavy rainfall events. The pressure showed both increasing and decreasing trends during heavy rainfall events however in five of six cases a tight pressure gradient was present producing an influx of moist air into the flood area. Onshore winds were found to be of high importance in heavy rainfall events to bring moist air into the area. Wind speeds greater than 5m/s occurred during times of high rainfall intensities.

- Description: There is a gap in healthcare service delivery within low resource settings of South Africa. These areas are under-serviced because of poor health infrastructure and few available medical experts. This contributes immensely to poor health care delivery especially to chronically ill diabetic patients and increases mortality rates. However, innovative remote patient monitoring (RPM) systems have been developed to curb the above challenge in recent years. Unfortunately, most of these systems are standalone and are incompatible with one another. Most of them relay on Internet for connectivity which is imminent in low resource settings. This makes continuity of care of chronic ill patients a great challenge. Additional, the efficacy and feasibility of RPM using mobile phones in low resource settings of South Africa are still unknown. It was also noted that none of these systems have been developed for a clinical trial. The goal of this study was to provide a standard framework that allows optimal design of mobile RPM systems which are interoperable. The objectives were to investigate the RPM system efficacy and reliability in low resource settings and determine its effects on clinical management, self-care and health outcomes. The framework was validated with a clinical trial to remotely monitor diabetic adults in Limpopo province of South Africa. A prototype system was developed based on sound user centric design process and enterprise architectural principles to remotely monitor diabetic elderly patients using cellular technologies and existing hospital infrastructure. It was evaluated using a controlled, randomized clinical trial for 6 months. There were 120 patients who took part in the study and were categorized into two groups, the intervention Group X and the control Group Y. Each group comprised of 60 participants. Evidence from this study justified the feasibility and possibility of long term implementation of RPM system to cater for chronic ill patients in low resource settings worldwide. Results showed that the self-care and normal blood glucose levels improved for both groups whereas quality of life improved only for Group X. It was shown that extensive self-care knowledge with the help of RPM system improved self-care and helped normalize their glucose levels. The hospital admissions and mortality between the two groups did not differ much. However, the intervention group had more hospital visits than the control group because the participants were requested to visit the hospitals in case of emergency. The users perceived the RPM system as feasible and effective way of clinical management and self-care. Due to wide acceptance, some patients were even willing to continue using the system after the trial. Home measurements proved to be reliable and helped improve self-care. In future, a standardized and unified framework based on rule set would provide comprehensive remote healthcare allowing continuous patient monitoring at a reduced overall cost thereby decreasing mortality rates.

- Description: The performance measurement of a service provider network is an important activity. It is required for the smooth operation of the network as well as for reporting and planning. SANReN is a service provider tasked with serving the research and education network of South Africa. It currently has no structure or process for determining network performance metrics to measure the performance of its network. The objective of this study is to determine, through a process or structure, which metrics are best suited to the SANReN environment. This study is conducted in 3 phases in order to discover and verify the solution to this problem. The phases are "Contextualisation", "Design",and "Verification". The "Contextualisation" phase includes the literature review. This provides the context for the problem area but also serves as a search function for the solution. This study adopts the design science research paradigm which requires the creation of an artefact. The "Design" phase involves the creation of the conceptual network performance measurement model. This is the artefact and a generalised model for determining the network performance metrics for an NREN. To prove the utility of the model it is implemented in the SANReN environment. This is done in the "Verification" phase. The network performance measurement model proposes a process to determine network performance metrics. This process includes getting NREN requirements and goals, defining the NRENs network design goals through these requirements, define network performance metrics from these goals, evaluating the NRENs monitoring capability, and measuring what is possible. This model provides a starting point for NRENs to determine network performance metrics tailored to its environment. This is done in the SANReN environment as a proof of concept. The utility of the model is shown through the implementation in the SANReN environment thus it can be said that it is generic.The tools that monitor the performance of the SANReN network are used to retrieve network performance data from. Through understanding the requirements, determining network design goals and performance metrics, and determining the gap the retrieving of results took place. These results are analysed and finally aggregated to provide information that feeds into SANReN reporting and planning processes. A template is provided to do the aggregation of metric results. This template provides the structure to enable metrics results aggregation but leaves the categories or labels for the reporting and planning sections blank. These categories are specific to each NREN. At this point SANReN has the aggregated information to use for planning and reporting. The model is verified and thus the study’s main research objective is satisfied.

- Description: The fact that information is ubiquitous throughout most modern organisations cannot be denied. Information is not merely used as an enabler in modern organisations today, but is also used to gain a competitive advantage over competitors. Thus, information has become one of the most important business assets. It is, therefore, imperative that organisations protect information assets as they would protect other business assets. This is typically achieved through implementing various security measures.Technological and procedural security measures are largely dependent on humans. However, the incorrect behaviour of humans poses a significant threat to the protection of these information assets. Thus, it is vital to understand how human behaviour may impact the protection of information assets. While the focus of much literature is on organisations, the focus of this research is on higher education institutions and the factors of information security, with a specific focus on influencing the information security behaviour of computing graduates. Typically, computing graduates would be employed in organisations in various careers such as software developers, network administrators, database administrators and information systems analysts. Employment in these careers means that they would be closely interacting with information assets and information systems. A real problem, as identified by this research, is that currently, many higher education institutions are not consciously doing enough to positively influence the information security behaviour of their computing graduates. This research presents a model to address various factors that could influence the information security behaviour of computing graduates. The aim of this model is to assist computing educators in influencing computing graduates to adopt more secure behaviour, such as security assurance behaviour. A literature review was conducted to identify the research problem. A number of theories such as the Theory of Planned Behaviour, Protection Motivation Theory and Social Cognitive Theory were identified as being relevant for this research as they provided a theoretical foundation for factors that could influence the information security behaviour of computing graduates. Additionally, a survey was conducted to gather the opinions and perceptions of computing educators relating to information security education in higher education institutions. Results indicated that information security is not pervasively integrated within the higher education institutions surveyed. Furthermore, results revealed that most computing students were perceived to not be behaving in a secure manner with regard to information security. This could negatively influence their information security behaviour as computing graduates employed within organisations. Computing educators therefore require assistance in influencing the information security behaviour of these computing students. The proposed model to provide this assistance was developed through argumentation and modelling.

- Description: The Russian Wheat Aphid (Diuraphis noxia Kurdjumov, 1913) (RWA) is a serious pest of grain crops and is of considerable concern in South Africa, particularly in terms of barley grown specifically for the brewing industry. This paper highlights the effect of a small (50 ppm) increase in [CO2] on the growth rate of the four South African RWA biotypes on the SABBIErica barley cultivar. Controlled environment experiments revealed that the colony growth rate for RWASA4 was significantly lower than SA1 under ambient conditions as well as significantly lower than SA1, SA2 or SA3 under elevated CO2 conditions. The unexpected difference suggested an atypical, non-preferential feeding habit on SABBIErica, for RWASA4. The small RWASA4 colonies inflicted similar morphological damage to the significantly larger RWASA1 – RWASA3 biotype populations — indicative of potential hypervirulence under elevated CO2. The continuous feeding of RWASA biotypes causes damage to the transport system as well as substantial, catastrophic damage to mesophyll chloroplasts as well as mitochondria within the host plant's leaves. The TEM study revealed evidence of sequential/systematic degeneration of chloroplasts and mitochondria with continued aphid feeding, which we suggest is an indication of potential emergent hypervirulence under elevated CO2 conditions.

- Description: The movement of adults and children between households in South Africa is a tradition entrenched by apartheid state policies and fuelled by poverty and HIV/AIDS. Children affected by domestic mobility include not only orphans, but those whose families are struggling financially or are deprived of income through illness or death. One example of domestic mobility is the redistribution of children through grandmother-headed households. While domestic mobility has been researched from a number of different academic perspectives, there is scanty psychological literature on the subject, and a gap around children’s experiences of their own mobility. Children’s roles and agency in their mobility, and how these are shaped by their environments, social relations and resilience, are not considered. This research aimed to explore the meanings that domestic mobility had in the lives, identity constructions and personal narratives of South African children currently residing in grandmother-headed households in the Eastern Cape. This was achieved through a narrative approach, interested in big life-stories, as well as small stories of everyday interaction. Over the course of two years, five child participants aged between eight and 12 years constructed narrative material through participatory action research methodologies, including the mapping of time-lines and their lived environments, and photovoice. Child participants and their families were selected from the client-base of a non-governmental organisation, Isibindi (Alice). Narratives were analysed as case studies to tell detailed stories of children’s lives, and to comment on issues associated with domestic mobility, socio-economic status, gender, education, HIV/AIDS and social protection. The study found that blanket definitions of poverty and domestic mobility conceal important variations in levels of poverty and individual experiences of mobility. While children are excluded from processes of decision-making about their mobility, they perform their agency by contributing to household survival and ensuring the continuation of mutually beneficial attachment relationships. This research argues that interventions which act on various systemic levels (macro, meso and exo) add support and protection for vulnerable children. This research also argues for psychological “scaffolding” of potentially traumatic or precarious processes, such as domestic mobility and deaths in families, through caregivers preparing and consulting with children before events happen.

- Description: In modern society, cyberspace is interwoven into the daily lives of many. Cyberspace is increasingly redefining how people communicate as well as gain access to and share information. Technology has transformed the way the business world operates by introducing new ways of trading goods and services whilst bolstering traditional business methods. It has also altered the way nations govern. Thus individuals, organisations and nations are relying on this technology to perform significant functions. Alongside the positive innovations afforded by cyberspace, however, those who use it are exposed to a variety of risks. Cyberspace is beset by criminal activities such as cybercrime, fraud, identity theft to name but a few. Nonetheless, the negative impact of these cyber threats does not outweigh the advantages of cyberspace. In light of such threats, there is a call for all entities that reap the benefits of online services to institute cybersecurity. As such, cybersecurity is a necessity for individuals, organisations and nations alike. In practice, cybersecurity focuses on preventing and mitigating certain security risks that might compromise the security of relevant assets. For a long time, technology-centred measures have been deemed the most significant solution for mitigating such risks. However, after a legacy of unsuccessful technological efforts, it became clear that such solutions in isolation are insufficient to mitigate all cyber-related risks. This is mainly due to the role that humans play in the security process, that is, the human factor. In isolation, technology-centred measures tend to fail to counter the human factor because of the perception among many users that security measures are an obstacle and consequently a waste of time. This user perception can be credited to the perceived difficulty of the security measure, as well as apparent mistrust and misinterpretation of the measure. Hence, cybersecurity necessitates the development of a solution that encourages acceptable user behaviour in the reality of cyberspace. The cultivation of a cybersecurity culture is thus regarded as the best approach for addressing the human factors that weaken the cybersecurity chain. While the role of culture in pursuing cybersecurity is well appreciated, research focusing on defining and measuring cybersecurity culture is still in its infancy. Furthermore, studies have shown that there are no widely accepted key concepts that delimit a cybersecurity culture. However, the notion that such a culture is not well-delineated has not prevented national governments from pursuing a culture in which all citizens behave in a way that promotes cybersecurity. As a result, many countries now offer national cybersecurity campaigns to foster a culture of cybersecurity at a national level. South Africa is among the nations that have identified cultivating a culture of cybersecurity as a strategic priority. However, there is an apparent lack of a practical plan to cultivate such a cybersecurity culture in South Africa. Thus, this study sought firstly to confirm from the existing body of knowledge that cybersecurity culture is indeed ill-defined and, secondly, to delineate what constitutes a national cybersecurity culture. Finally, and primarily, it sought to devise a national strategy that would assist SA in fulfilling its objective of cultivating a culture of cybersecurity on a national level.

This increase in volume has raised significant chal-lenges for administrators in terms of how to identify threats in amongst the large volumes of network traffic, a large part of which is often back-ground noise. In this paper we propose a framework for scoring and coding NetFlow data with security related information. The scores and codes are added through the application of a series of independent tests, each of which may flag some form of suspicious behaviour. The cumulative effect of the scoring and coding raises the more serious po-tential threats to the fore, allowing for quick and effective investigation or action. The framework is presented along with a description of an implementation and some findings that uncover potentially malicious network traffic.

- Description: Efavirenz, a drug that is still inaccessible to millions of people worldwide, is potent non nucleoside reverse transcriptase inhibitor (NNRTI), is one of the preferred agents used in combination therapy for first-line treatment of the human immunodeficiency virus (HIV). NNRTIs attach to and block an HIV enzyme called reverse transcriptase, by blocking reverse transcriptase; NNRTIs prevent HIV from multiplying and can reduce the amount of HIV in the body. Efavirenz can't cure HIV/AIDS, but taken in combination with other HIV medicines (called an HIV regimen) every day helps people with HIV live longer healthier lives. Efavirenz also reduces the risk of HIV transmission and can be used by children who are suffering from HIV/AIDS. All the above therapeutic uses of efavirenz prompted us to identify the novel and hopefully cost efficient synthetic methodology for the preparation of efavirenz. In this thesis a new synthetic method for asymmetric synthesis of efavirenz is described. This route started from commercially available starting materials and it is first established in traditional batch chemistry and further the parameters transferred to a semi continuous flow protocol for optimization.

- Description: With the changing landscape in South Africa to a full democracy, increased research has been undertaken in the psychometric field on local and national normative studies regarding various assessment measures. The Raven’s Coloured Progressive Matrices (CPM) is one of the measures that have already been extensively normed throughout the world for various population groups. In South Africa, local norms for normal populations of children have been developed by groups of researchers in the Grahamstown (Eastern Cape) as well as the Bloemfontein (Free State) areas. With a South African school educational system that focuses on Inclusive Education, there is a growing need for mainstream schools to identify learners who are at risk for learning disabilities in order to develop appropriate supportive intervention plans. The research aimed to establish psychometric normative screening data based on the Raven’s CPM, and to compare these with the established and published international and local Raven’s CPM norms. In addition, the researcher developed pilot classification scores for the early screening and detection of at risk learners in order to encourage the potential role and use of the Raven’s CPM in the identification of cognitive learning barriers. The sample consisted of 388 primary school learners identified as having cognitive barriers to learning. Archival data was used that was gathered from a Psychological clinic that provided screening services to schools in the Nelson Mandela Metropolitan area. The results of the study indicated that there was a proportional relationship between age and test performance. Gender differences were found where the males in this study outperformed the females. There was a significant difference in the Raven’s CPM test performance with respect to the grade levels of the learners. The study developed a special set of norms with cognitive classification scores that will aid in the early identification of learning disabilities.

- Description: This research looked at a participant-focused sociological analysis of Beedz, a Grahamstown skills training project for women. Beedz is run by the River of Life Church and aims to equip women with the necessary skills to participate in the economy, either as entrepreneurs or as employees. Using third world feminist theory, this research explored the experiences of women who have participated in the Beedz programme, what they went through, and whether the programme benefited them or not. In particular, this research explored how the participants experienced Beedz as a programme for women without an exclusive focus on traditional feminist issues. This research was qualitative in nature; with in-depth, semi-structured interviews being used as a means of data collection. Data was analysed using key themes emerging from the interviews. The key findings of this research were that it is important to include women in training projects, as by including them you create spaces and enabling environments for women to empower themselves. Secondly, although Beedz does not deliberately work from the third world feminist theory, it could be argued that it fits in this framework as this programme facilitates skills training through looking at women as a whole, taking into account not only their gender, but also their class and race. Recommendations were made on how the Beedz programme may be improved, based on the information gathered from the participants from the interviews conducted during the research, with the key recommendation being that the organisers of the programme need to create a space for the participants’ voice to be heard, so that the programme can be relevant and beneficial to them.

A participatory action research approach to engaging peer educators in the prevention of teenage pregnancy

- Description: The phenomenon of teenage pregnancy among school-going youth is on the increase in South Africa, despite the existence of a number of intervention programmes. Although both curricular and co-curricular awareness programmes targeting this phenomenon are currently employed within South African schools, these programmes have patently not met with much success, since the problem remains acute. It was the question why these programmes are not succeeding in alleviating the problem that prompted my interest in undertaking this study. Based on literature that suggests that those programmes that are successful in reaching the youth are designed through participatory processes, rather than being designed by outside experts, my thesis proposes that prevention programmes that are designed and implemented by the youth for the youth may be more successful in helping them to make healthy decisions in terms of their sexual behaviour. This study attempted to engage youth in a participatory way in identifying and exploring their perceptions of teenage pregnancy and using the knowledge thus gained to design, implement and evaluate prevention strategies in their school. The study is informed by social learning theory and adopted a participatory action research (PAR) design, which is located in a critical paradigm. I purposefully recruited twenty-four youths (14 females and 10 males) to participate. The primary research question that guided this study was: “How can peer educators be engaged to create prevention strategies to reduce teenage pregnancy and its impacts?” The following sub-questions were identified from the primary research question: What do learners themselves know feel and experience with regard to the causes and effects of teenage pregnancy How might a participatory methodology help learners to create relevant and contextualised strategies for addressing teenage pregnancy? How can such strategies be implemented in a school system? What recommendations could be made for addressing teenage pregnancy in a contextualised way? The research was conducted in two cycles. In Cycle One, data was generated through two focus group discussions, led by a young researcher from the community to encourage openness and honesty. In addition through snowball sampling, six teenage mothers and two teenage fathers agreed to be interviewed individually. The same questions were asked in the two discussions and the individual interviews, namely: “What do you know, feel and think about teenage pregnancy?” In the first cycle, I responded to my first sub-research question. Interviews, drawings and focus group discussions were used to generate data. Three themes emerged from the data to provide insight into how the youth at the school perceived the phenomenon of teenage pregnancy. The findings from this cycle revealed certain tensions between what youth said they needed and what adults, such as teachers and parents, thought they needed to know. The participating teenagers regarded themselves as sexual beings, while the adults in their sphere of influence preached abstinence, moralised or merely cited the facts, without entering into any discussion of how young people could deal with social pressures and better protect themselves against unplanned pregnancy. The participating youth were clearly aware of how to prevent pregnancy, but the social barriers to using condoms or contraceptive pills were a stumbling block. They possessed knowledge of the potential consequences of risky behaviour, but this did not stop them from engaging in such behaviour. In the second cycle of the research, the participants used the findings of the first cycle to develop prevention messages and strategies to convey these messages to their peers. They used participatory visual methods to accomplish this. The findings from this cycle revealed that a peer education approach helped participants to increase maturity in sexual decision-making, had a positive effect on the learning and acquisition of new skills, and improved critical thinking relating to sexuality. The study also had a positive impact on other learners’ knowledge and the attitudes displayed by both learners and teachers, and also led to improvements in school policies related to sexuality education. It is contended that the study contributed important theoretical and methodological insights. Knowledge generated from the study could make a contribution to the field of sexuality education and how it should be approached in schools, particularly in communities facing social and economic adversity. The methodological contribution of this study provided guidelines and theory on how participatory action research and participatory methods can be implemented in schools to enable youth to influence change in their schools, not only regarding teenage pregnancy, but also other social issues.

Based on literature that suggests that those programmes that are successful in reaching the youth are designed through participatory processes, rather than being designed by outside experts, my thesis proposes that prevention programmes that are designed and implemented by the youth for the youth may be more successful in helping them to make healthy decisions in terms of their sexual behaviour. This study attempted to engage youth in a participatory way in identifying and exploring their perceptions of teenage pregnancy and using the knowledge thus gained to design, implement and evaluate prevention strategies in their school. The study is informed by social learning theory and adopted a participatory action research (PAR) design, which is located in a critical paradigm. I purposefully recruited twenty-four youths (14 females and 10 males) to participate. The primary research question that guided this study was: “How can peer educators be engaged to create prevention strategies to reduce teenage pregnancy and its impacts?” The following sub-questions were identified from the primary research question: What do learners themselves know feel and experience with regard to the causes and effects of teenage pregnancy How might a participatory methodology help learners to create relevant and contextualised strategies for addressing teenage pregnancy? How can such strategies be implemented in a school system? What recommendations could be made for addressing teenage pregnancy in a contextualised way? The research was conducted in two cycles. In Cycle One, data was generated through two focus group discussions, led by a young researcher from the community to encourage openness and honesty. In addition through snowball sampling, six teenage mothers and two teenage fathers agreed to be interviewed individually. The same questions were asked in the two discussions and the individual interviews, namely: “What do you know, feel and think about teenage pregnancy?” In the first cycle, I responded to my first sub-research question. Interviews, drawings and focus group discussions were used to generate data. Three themes emerged from the data to provide insight into how the youth at the school perceived the phenomenon of teenage pregnancy. The findings from this cycle revealed certain tensions between what youth said they needed and what adults, such as teachers and parents, thought they needed to know. The participating teenagers regarded themselves as sexual beings, while the adults in their sphere of influence preached abstinence, moralised or merely cited the facts, without entering into any discussion of how young people could deal with social pressures and better protect themselves against unplanned pregnancy. The participating youth were clearly aware of how to prevent pregnancy, but the social barriers to using condoms or contraceptive pills were a stumbling block. They possessed knowledge of the potential consequences of risky behaviour, but this did not stop them from engaging in such behaviour. In the second cycle of the research, the participants used the findings of the first cycle to develop prevention messages and strategies to convey these messages to their peers. They used participatory visual methods to accomplish this. The findings from this cycle revealed that a peer education approach helped participants to increase maturity in sexual decision-making, had a positive effect on the learning and acquisition of new skills, and improved critical thinking relating to sexuality. The study also had a positive impact on other learners’ knowledge and the attitudes displayed by both learners and teachers, and also led to improvements in school policies related to sexuality education. It is contended that the study contributed important theoretical and methodological insights. Knowledge generated from the study could make a contribution to the field of sexuality education and how it should be approached in schools, particularly in communities facing social and economic adversity. The methodological contribution of this study provided guidelines and theory on how participatory action research and participatory methods can be implemented in schools to enable youth to influence change in their schools, not only regarding teenage pregnancy, but also other social issues.

A perfect end: a study of syllable codas in South African Sign Language

- Description: Coda constraints are common in spoken languages. German, for example, can only have voiceless obstruents in the coda position (Lombardi 1999). Most sign language research has been on other sign languages, most notably American Sign Language (ASL). This research serves to contribute to syllable theory and has a methodology that allows for cross-linguistic research, strengthening the understanding of sign languages in general, and enhancing the description of SASL in particular. It is well known that syllables in spoken languages require a vowel nucleus to be well-formed. Sandler and Lillo-Martin (2006) provide evidence of sign languages requiring movement to be considered well-formed: even seemingly stationary signs such as WHO, which occurs at the chin, will have finger wiggling as some form of movement. It is thus natural to assume that movement is akin to vowels in syllable theory (Brentari 1998). Thus, locations are similar to consonants. However, the visual nature of sign allows for simultaneity - holds do not occur by themselves. Next to location, handshapes are phonetically complex features that may impact the constraints at coda position. To my knowledge, there is no formal research on the coda constraints of sign language syllables. The data examined here comes from a video dictionary of approximately 175 words. From this dictionary, a database of coded locations and handshapes are recorded for both the onset and the coda. From this, a consonant inventory is made and patterns are identified. Each source of data is analysed individually based on Brentari’s (1998) Prosodic Model. Patterns that are noticed are then looked at using Brentari’s (1998) framework to account for what phonological rules are dictating constraints. However, as a hearing researcher cannot claim native knowledge of a sign language, the conclusions drawn from the data will be tested using native SASL signers for negative judgement. The preliminary findings of the research suggest that there are constraints on the coda location and handshape of a sign and that this may be a result of the natural classes of handshape and location prohibiting certain onset-coda combinations. The onset and coda on monosyllabic signs mirror each other’s location, while the handshape cannot change in repeated and many monosyllabic signs. These constraints provide more understanding into the rich phonological nature of sign languages.

- Description: South African Sign Language (SASL) is an understudied language with a rich and interesting phonology. For instance, while the language allows onsetless syllables, it does not allow codaless syllables, except in a small class of signs which do not include path movement. This article identifies and defines possible constraints on syllable codas in SASL. Using a video dictionary as data, we have coded handshapes at locations occurring at the onset and coda of the more common signs in the lexicon. In handshape, it has been found that the selected fingers may move to create different handshapes in the coda position, but that these coda handshapes are often [1], [5], [A], [Å] or [S], which are the unmarked handshapes of the non-dominant hand in asymmetrical two-handed signs (Sandler and Lillo-Martin 2006). Furthermore, the joint specification for the selected fingers can also vary in the coda position, but there appear to be strict limitations on which joint combinations are permitted in the onset-coda relationship. There are also constraints on coda location. The major body region can change within a single syllable, and the preferred body regions in the coda position are [body] and [H2]. It is evident not only that handshape and location constraints occur at the coda position, but that these constraints show patterns similar to coda neutralisation in many spoken languages.

- Description: Massively multiplayer online games (MMOG’s) are a specific form of online computer games that allow for millions of people to simultaneously play online at any time. This form of online gaming has become a huge phenomenon worldwide both as a popular past time and a business endeavour for many individuals. There are more than 16 million people worldwide who subscribe to fantasy role-playing online games. Although such games can provide entertainment for many people, they can also lead to problematic Internet use (PIU). PIU has also been referred to as Internet addiction, and can cause significant problems in an individual’s functioning. The study aimed to enhance a greater understanding of the phenomenon of male adults’ experiences PIU with MMOG’s. More specifically the study aims to identify if PIU with MMOG’s can be considered a form of Internet addiction within South Africa. Furthermore, assisting in the further development of online addiction diagnosis and treatment strategies. The study utilised an interpretive phenomenological approach (IPA) and participants were purposively sampled. The data was collected using semi-structured individual interviews. Furthermore, Braun and Clarks thematic analysis was used during data analysis while incorporating the four major processes in phenomenological research, namely 1) epoche, 2) phenomenological reduction, 3) imaginative variation and, 4) synthesis. Themes that emerged from the analysis of the participants’ experiences included, initial description of use, motives for continued use of MMOG’s, consequences of PIU with MMOG’s, perceptions of PIU with MMOG’s, and treatment considerations. This study provided a thick description of South African and international literature and combines the literature with the themes that emerged from the participants experiences in order to produce discussions based on the findings of this qualitative study. Conclusions, recommendations, and limitations of this study informed future research on cyber citizenship by providing a detailed understanding of the context of South African male adults’ experiences of PIU with MMOG’s.

A political discourse analysis of social memory, collective identity and nation-building in the Sunday Mail and the Standard of Zimbabwe between 1999 and 2013

- Description: Although much effort has been expended on studying many sites of social memory, little attention has been directed at the media’s work of memory, especially in post-colonial Africa. The media’s work of memory is important because of its social standing as a communicative and cultural institution, and because social memory is imbricated in processes of both collective identity formation and nation-building which partly shape patterns of economic distribution, recognition, and representation in society. It is in this context that this study shows how Zimbabwe’s The Sunday Mail and The Standard newspapers used social memory to construct the country’s national identity between 1999 and 2013 in the context of a socio-economic and political crisis for the country’s poly-racial, and poly-ethno-linguistic communities. The study also explores how these newspapers worked as memory sites through their construction of Zimbabwe’s national identity during the period under study. It achieves these tasks by analysing how these newspapers reported on such issues as Zimbabwe’s colonial history, the country’s narrative of decolonisation, the Gukurahundi narrative, the land reform process, elections and independence celebrations. The study takes a critical realist approach to qualitative research, and uses Fairclough and Fairclough’s (2012) method of political discourse analysis as well as Aristotle’s approach to rhetoric for a close reading of the sampled newspaper articles. It is informed by Nancy Fraser’s Theory of Justice, Chantal Mouffe’s Model of Agonistic Pluralism, and Jurgen Habermas’s Discourse Ethics Theory. The study concludes that these two newspapers actively use social memory to construct versions of national identity for specific socio-political and economic ends. Editorials and opinions from The Sunday Mail, which construct Zimbabwean-ness in nativist terms represent the hegemonic appropriation of social memory to construct a sense of Zimbabwean nationhood. In contrast, The Standard uses social memory to construct Zimbabwean-ness in modernist terms with citizenship as the core organising principle of belonging. The political discourse analysis of The Sunday Mail’s and The Standard’s evocation of social memory shows that the two newspapers reflect the tension between indigenist and universalist imaginaries of belonging in Zimbabwe. But the newspapers’ construction of belonging in Zimbabwe is informed by justice claims as seen from each of their political standpoints. As such, their respective definitions of Zimbabweans’ justice claims in terms of their political standpoints, also propose how those justice claims should be addressed and who stands to benefit from them.

The development of fitness trackers and their associated software aid consumers to understand the manner in which they may improve their physical wellness. These devices are capable of collecting health data for a consumer such sleeping patterns, heart rate readings or the number of steps taken by an individual. Although, this information is very beneficial to guide a consumer to a better healthier state, it has been identified that they have privacy and security concerns. Privacy and Security are of great concern for fitness trackers and their associated applications as protecting health data is of critical importance. This is so, as health data is one of the highly sort after information by cyber criminals. Fitness trackers and their associated applications have been identified to contain privacy and security concerns that places the health data of consumers at risk to intruders. As the study of Consumer Health continues to grow it is vital to understand the elements that are needed to better protect the health information of a consumer. This research paper therefore provides a conceptual threat assessment framework that can be used to identify the elements needed to better secure Consumer Health Wearables. These elements consist of six core elements from the CIA triad and Microsoft STRIDE framework. Fourteen vulnerabilities were further discovered that were classified within these six core elements. Through this, better guidance can be achieved to improve the privacy and security of Consumer Health Wearables.
