- Description: The research shows the critical success factors when implementing information security projects. Many Information security projects in the past have not been successful because these factors were not identified and emphasised effectively. By identifying these factors the research basically presents a model by which information security projects can be executed with guaranteed success. The factors identified during the study cover the following streams: top management commitment as a factor of success; accountability as a factor of success; responsibility as a factor of success; awareness as a factor of success and an information security policy as a factor of success. For the empirical study, a physical questionnaire was administrated to a pool of experts in project management and information security. The study consisted of 60 participants who were verified to have minimum requirements core for questionnaire completion. The questionnaire requested for biological information of the participants and their perceived relations (based on their experience) between project success versus accountability, information security project success versus responsibilities, information security project success versus training & awareness, information security project success versus top management commitment and information security project success versus information security policy. The participants’ responses were structured according to a Likert-type scale. Participants had to indicate the extent to which they agreed with each of the statements in the questionnaire. The responses obtained from the survey were presented and analysed. The researcher observed in this study that information security projects are so specific that critical success factors need to be emphasised from project inception. With the identified critical success factors, the researcher recommends that a project methodology be structured to include these factors so that there is a standard in running information security projects successfully. The researcher also identified that amongst the critical success factors identified, there are some that need to be emphasised more than the others due to their level of importance in such projects.

- Description: The study uses domestication of technology and Cultural Studies theories to investigate how youth in three institutions of tertiary learning in Harare, Zimbabwe are accessing health-related information online using their smart phones. The study critically examines how youths deploy these digital media technologies to construct their identities in a context where social and political power is unevenly distributed. To understand these issues, the study uses a triangulated research design comprising a social survey, in-depth individual interviews and field observation for data collection. Results from this data gathering showed that the use of digital media technologies differ across gender, at least in terms of the distribution of online health seeking practices between male and female youths. According to the survey results, more women tend to use their mobile phones to access health-related information. Data from the individual in-depth interviews showed that the most significant site of social change (social disruption) relates to how digital media facilitates emerging new identities (i.e. identity in the broader sense as well as health-related and sexual health identities). For both young men and young women, mobile phones are used precisely for image management, peer acceptance and the desire to define respective feminities and masculinities within their social networks. Both male and female youths assert they are able to access a variety of information online, and some of this information would not easily accessible when sought from traditional structures such as their parents. This way, youth feel that digital media technologies allow them to cultivate their own preferred identities outside the purview of parental authority and social control. Drawing on postmodern literature, such emerging identities are predicated on cultural volatility, unpredictability, decentralisation and refusal to fixation and conformity to socially constructed identities about being a youth, or being a young Zimbabwean woman or man, for example. Thus, the use of mobile phones and mobile Internet by youths in Zimbabwe to access health-related information has sociopolitical significance, because it allows young people to fashion preferred identities that resists entrenched regimes of social power. For young people in Zimbabwe, online health seeking practices precisely reflects attempt towards negotiating with and circumvent the structural limitations of either an expensive health care system or the general curiosity associated with growing up. That way, it is arguable that youth use digital media technologies to help them exercise some level of social autonomy and agency in dealing with everyday life. Individual in-depth interviews demonstrated that mobile phones and mobile Internet can thus be seen as opening up more spaces for youth to learn more about issues about growing up, sexuality and adolescents that a conservative society such as Zimbabwe traditionally consider as ‘inappropriate’ for youth consumption. They argued that the inability of parents to discuss with them issues about growing up often result in them “finding out on our own” using digital media technologies to satisfy the desire to wean themselves from what they view as arbitrary and asymmetrical social power. The study demonstrated that youth use the mobile phone to challenge the social world of adults and to show resistance to it, thereby strengthening a subculture as well as constructing an identity. However, despite the positive attributes of social capital, connectivity and personalised experience afforded by the mobile phone, the mobile phone is sometimes a source of conflict in relationships between young men and women; that is, between unmarried partners. Young women reported that their boyfriends often force them to disclose who they communicate with using their mobile phones. They also reported that their boyfriends often did some random surveillance of their social media contacts and activities. Thus, whilst one of the mobile phone’s most powerful attribute is its ability to offer personalised experience, as well as offer synchronised and unlimited access to distant connections, results from in-depth interviews showed that some unwritten expectations and norms dictated that young men closely watch their ‘girlfriends’ social media activities, including their online search activities. As a result, privacy as well as the much touted relationship between mobile phone and women’s autonomy becomes contested arenas. Even at young ages, and before marriage, women are socialised to show subservience to their partners by allowing them access to their mobile phones.

- Description: Changing perceptions of literacy over the past few decades have produced new approaches to the problem of how best to improve the literacy competence of primary school learners. Literacy remains a continuous problem in South Africa, as learners lack motivation to read or are struggling to read, write, and learn in a language that is unfamiliar to them. Researchers such as Street (2005) believe that literacy should not be viewed only as a set of skills to be mastered, but rather as something which must be understood in its broader social context. In accordance with this theory, the South African organisation PRAESA uses their Nal'ibali campaign to promote 'reading for enjoyment' and the formation of 'reading clubs' in order to improve learners' motivation to read and thus their literacy competence by increasing their exposure to pleasurable reading experiences. In this study it is argued that reading for enjoyment is beneficial to primary school learners' literacy competence as well as their personal and social development. In this study, Grade 5, 6, and 7 learners belonging to the reading club at a primary school in Port Elizabeth were observed over a six-month period. Data was collected through ethnographic observation of the reading club sessions and compiled into a detailed expository and sequential report. This narrative was then analysed in order to determine to what extent the learners had benefited in terms of their development from their participation in the reading club's activities. The analysis of the narrative demonstrated that learners' literacy competence, as well as personal and social skills such as self-confidence and tolerance, had been enhanced by the learners' voluntary participation in enjoyment-centred experiences with literacy. The findings of this study demonstrate that, in under-resourced schools and communities lacking a strong reading culture, an extra-curricular 'reading club' with a focus on reading for enjoyment was able to improve learners' literacy skills and provide opportunities for holistic growth by increasing learners' motivation to read.

- Description: Agricultural development is back on the development agenda. Even though the smallholder farmers are in the majority and at the forefront in terms of food production and agriculture being the backbone of the economy of Zimbabwe, there is no clearly defined policy on smallholder agriculture in Zimbabwe. The food insecurity has remained a continuous challenge for the rural poor in Zimbabwe. This study investigated the contribution of smallholder agriculture to food security with particular reference to the Masvingo province. The study employed qualitative method of research entailing extensive review of literature as a method of data collection. The study utilized the modernisation theory and sustainable livelihoods framework to illustrate smallholder agriculture and food security nexus. The study revealed that smallholder agriculture is the best option for addressing food security since agriculture is considered the main livelihood strategy for small scale farmers in Zimbabwe. There is general scholarly consensus that the main cause of food insecurity in Zimbabwe is a decrease in smallholder agriculture productivity. The study revealed that poor infrastructure , limited access to credit, limited access to inputs, poor investment in human development, limited access to markets and harsh climatic conditions weaken the capacity of small scale farmers to improve food security. Key recommendations are that supportive institutions need to be put in place to strengthen the smallholder farmer’s capacity to improve food security in Zimbabwe.

- Description: Communal rangelands occupy 13 percent of the agricultural land in South Africa, and these rangelands serve as a source of feed to livestock. These areas are threatened by bush encroachment due to poor rangeland management. This study was conducted in Alice (Sheshegu communal area) and the objective was to assess farmers' perceptions and the impact of bush encroachment on herbaceous vegetation and soil nutrients. Structured questionnaires were used to assess indigenous knowledge of communal farmers on the impact of bush encroachment on rangelands. Fourty (40) respondents from households who owned livestock were randomly selected and interviewed at Sheshegu village. About 89 percent of communal farmers perceived that change of their grasslands to encroached savannas was caused by unreliable rainfall, prolonged drought, and poor rangeland management. Rangeland assessment was performed at four sites (Scattered, Moderate, Mixed and Dense bushland. 100mx50m were demarcated per site, and four 100m transects were laid parallel to each other, 30m apart. The step point method was used to determine both species composition and basal cover. Biomass production was determined by harvesting forage within randomly-paced a 0.25m2 quadrats. Aristada congesta and Eragrostis obtuse were the most dominating grass species in dense, mixed and moderate bushland. Scattered bushland was dominated by Themeda triandra. Biomass production increases with increase in bush density and basal cover improved from winter to summer season. Increaser grass species increase with the increase in bush density, this indicated that the rangeland was poorly managed and palatable species were being replaced by less palatable ones. Species composition of woody plants was determined within a 200m2 belt transect in all sites. Maytenus polycantha, Aloe ferox, Erehia rigida and lucas capensis were the most dominant woody species in Mixed bushland while Acacia karroo was most dominated in Scattered, Moderate and Dense bushland. Woody density showed no significant differences (P> 0.05) between Dense, Mixed and Moderate bushland. Woody plant density in all these sites exceed 2500 plants/ha, which showed that the rangeland was encroached with woody plants. Soil nutrient content was determined for each site. Five samples of soil were collected per site to test the effect of bush encroachment on soil nutrient composition. The concentration of nitrogen and soil pH increased with increase in bush density, while that of potassium, phosphorous, magnesium, sodium and sulphur showed no significant differences (P>0.05) across all homogenous vegetation units. The study revealed that Sheshegu communal farmers are aware of both negative and positive effects of encroachment on their community, and also argue that the government is not willing to support communal farmers in the process of reducing the spread of bush encroachment. It was concluded that the concentration of nitrogen and soil pH increased with increasing bush density and that bush encroachment had negative effects on herbaceous species. It was recommended that communal farmers should be formulating rangeland rules and regulations to manage rangeland resources. Rangeland rules and regulations should be based on the management of livestock management during grazing and harvesting of rangeland resources. The harvesting of woody and good timing of application of fire can also reduce the spread of bush encroachment. Veld resting and rotational grazing can also improve fuel load which is required for burning of woody plants. Furthermore, Department of agriculture should also provide workshops or training to communal farmers use different approaches or cheap ways of reducing bush encroachment and conserving rangeland resources.

- Description: In biological monitoring, deploying an effective standardised quantitative sampling method, optimised by trap design and sampling effort, is an essential consideration. To exemplify this using dung beetle (Coleoptera: Scarabaeidae: Scarabaeinae and Aphodiinae) communities, three pitfall trap designs (un-baited (TN), baited at ground level (flat trap, TF), and baited above the trap (hanging trap, TH)), employed with varying levels of sampling effort (number of traps = 1, 2, 3… 10; number of days = 1, 2, 3), were evaluated for sampling completeness and efficiency in the Eastern Cape, South Africa. Modelling and resampling simulation approaches were used to suggest optimal sampling protocols across environmentally diverse sites. Overall, TF recovered the greatest abundance and species richness of dung beetles, but behavioural guilds showed conflicting trends: endocoprids preferred TH while paracoprids and telocoprids preferred TF. Resampling simulation of trap type and the two components of sampling effort suggested that six TF traps left for three days was most efficient in obtaining a representative sample and allowed differentiation between trap types, allowing the improved efficiency to be recognised. The effect of trap type on non-target specimens, particularly ants, was also investigated. TF and TH caught almost no by-catch, which is ethically desirable.

- Description: Various researchers have investigated contributing factors towards the number of acute traffic incidences in and around Southern Africa. Some of these contributing factors include: the skills component of the driver predominately attributed to driving experience as well as the behavioural component influenced by the driver’s natural predisposition, individual differences and personality traits. In order to manage these factors drivers have developed varying coping mechanisms. One of these coping mechanisms is listening to music while driving, which is readily available in most cars and extensively used predominately during long duration driving. Listening to music neither increases one’s driving duration (as opposed to taking several breaks), nor does it interfere with the physical movements of driving (in the manner that eating and drinking may), but it might impact the concentration and attention of some drivers. This is based on the notion that music is assumed to impact arousal and cognitive ability. While there are several studies on the effect of music on driving performance and personality traits very few studies have looked at whether music has a positive or negative effect on driving performance based on differences in personality traits; and whether the extent of this effect might differ for different intensities of music? Consequently, this study aims to understand and determine the extent to which different personality traits predict the effect that listening to different music intensities has on driving performance. The impact of differing music conditions on the different personality traits used a repeated measures design and a between group design with respect to the personality traits with a sample size of (n=25)-16 females and 9 males-and their ages ranged between 19-35 years of age. The average age and standard deviation for this sample size was 22 years±2. A low-fidelity driving simulator task was utilised in order to provide a controllable, repeatable and a safe environment as compared to a real road situation. Personality was assessed using an online Big-Five Inventory scale (extraversion, agreeableness, conscientiousness, neuroticism, openness). All the different personality groups completed three conditions (45 minutes each) in a randomised order (without music, moderately loud music and loud music). Psychophysiological parameters i.e. heart rate frequency (HRF), heart rate variability (HRV) and eye movements (pupil diameter, eye speeds, fixation duration, blink frequency and blink duration) and driving performance were measured continuously. Subjective performance Multidimensional Driving Style Inventory was measured once-off prior to completion of the testing sessions, whilst the NASA-Task Load Index scale and Perceived control of participants were assessed after each condition. The expected outcomes revealed that music had an effect on objective driving performance (tracking deviation and reaction time) and psychophysiological measures only for participants of certain personality types while other personality types were unaffected by music. The subjective performance measures did not follow the same trend as objective performance measures. The conditions did not reveal an effect on driving performance, for most of the psychophysiological parameters and subjective measures. There was mainly a significant time on task effect and interactional effects on the psychophysiological measures (physiological and oculomotor) parameters at (p<0.05), but not on the subjective measures as anticipated. The study illustrated that the there are differences between personality traits. There was difficulty in the interpretation of the results based on the complexity of the findings for which each hypothesis was partially accepted. The research may establish practical implications for traffic safety campaigns in South Africa, as well as influence driving education for citizens. Assessing the personality trait would help to form an understanding as to which of the personality traits might be affected negatively from listening to music while driving and those that might benefit. Moreover, this study may assist motorists in understanding the implications of listening to music while driving as this may sometimes elicit risky driving behaviour and possibly cause an accident that may result in death.

- Description: Various researchers have investigated contributing factors towards the number of acute traffic incidences in and around Southern Africa. Some of these contributing factors include: the skills component of the driver predominately attributed to driving experience as well as the behavioural component influenced by the driver’s natural predisposition, individual differences and personality traits. In order to manage these factors drivers have developed varying coping mechanisms. One of these coping mechanisms is listening to music while driving, which is readily available in most cars and extensively used predominately during long duration driving. Listening to music neither increases one’s driving duration (as opposed to taking several breaks), nor does it interfere with the physical movements of driving (in the manner that eating and drinking may), but it might impact the concentration and attention of some drivers.

- Description: The purpose of this study was to assess the effectiveness of internal financial controls with specific reference to the Eastern Cape provincial department of basic education. A self-administered questionnaire was used to collect data. The questionnaire was filled by the respondents who are directly involved in processing payments and procuring for the departments. The findings have shown that Internal control system does exists within the department however the implementation and monitoring of its effectiveness needs to be strengthened. The findings show that the internal control system have an important role to play in attaining desired positive results within the department. Internal control effectiveness is one of the most important aspects in any organisation, whether in a private sector or in the public sector. It determines the stewardship of an entity’s management. The PFMA states that the accounting officer of a department must ensure that that department has and maintains effective, efficient and transparent systems of financial and risk management and internal control. If public officials could strictly adhere to the stipulated internal controls, there will be a positive response to accountability and also in service delivery as expected by the citizens. Public accountability gives a reflection on how does the entity conducts its business affairs in terms of adhering to the norms and standards as prescribed by the law and whether there are any strong controls to prevent acts of fraud and corruption.

- Description: The focal point of this study is to examine the print and online media representations of Jacqueline Phooko,a woman who accused former Cosatu General Secretary Zwelinzima Vavi of rape. Data for this study was obtained from eight South African newspapers and their websites. The study investigates whether the articles under review, including commentary and discussion online, focused on the incident itself or on the political landscape of South Africa. A content analysis was used to examine the data revelaling that Phooko was underrepresented and that most articles focused on Vavi’s political career. The research will use a feminist perspective to show that Phooko was under-represented in the media, in comparison to Vavi and his supporters who gained greater coverage, specifically in a political context. The significance of the findings is that although there are some strides achieved to have more women voices in the media however women are still under-represented.

- Description: Indigenous people tend to consult traditional healers when a family member manifests change in behaviour, whilst conventional treatment disregards spirituality when preserving mental health. The aim of the study was to explore the perceptions of indigenous people and the role of traditional healers in the management of mentally ill persons within the Cacadu District in the Eastern Cape Province of South Africa. The study has adopted a qualitative approach which was exploratory and descriptive in nature. The sample consisted of nine relatives of mental health care users (MHCUs) and six traditional healers. Ethical principles were also taken into consideration by the researcher during the process of conducting the study. Data were collected from two strata, namely, relatives of the MHCUs and the traditional healers and an interview guide was used to conduct in-depth face-to-face interviews. Data were analysed using Tesch’s method of data analysis. Four themes emerged from the data categories and sub categories were identified. According to the themes participants indicated the negative impact of mental illness; as a result they portrayed great desperation regarding the means of accessing a cure for mental illness. Some participants showed insufficient knowledge regarding mental illness and had different perceptions and beliefs regarding the origin of mental illness. Available literature was used to emphasise and support the views that were expressed by both traditional healers and relatives of MHCUs. It has been highlighted from this study that indigenous people of Cacadu District view mental illness as spiritual in origin but they include Western medication for the benefit of the mentally ill. In addition, the relatives of the MHCUs highlighted the economic burden as the major problem that results from mental illness.

- Description: Project management plays an important role as a common method of reinforcing chosen organisational strategies that leads to sustainable competitive advantage (Steyn, et al. 2013:5). Organisations that respond quickly to customer demands with the use of projects have more opportunities of adding value to their shareholders and increase their market share or responding faster to mitigate risk. A major challenge facing management in many manufacturing organisations is the increasing gap between big investment demands on one hand and the knowledge and expertise on the other hand of the teams that need to make the project a reality. The increasing recognition of failures encountered in projects to meet the expectations of their stakeholders are cited to be jeopardizing the economic development and growth many developing countries like South Africa. As such, organisations are forced to become more resourceful to reduce project failures in an effort to ensure that the positive project outcomes are realized. Relationship management has been identified as one of the aspects that can help improve coordination and communication between all parties involved in a project. As such, emotional intelligence provides a framework for interpersonal skills among project teams, which is claimed to contribute to project success (Clarke, 2010a:14; Davis, 2011:39)The contemporary study, therefore explored the relationship between emotional intelligence (EI) and success in project management. The study was conducted within the context of manufacturing projects in Continental Tyre South Africa (CTSA). Based on the main findings, it was concluded that emotional intelligence plays an important role in project success. Various recommendations from the results of the empirical study are presented in the final chapter.

- Description: The study aims to evaluate the biomass production and nutrient content and silage quality of perennial ryegrass (Lolium perenne (L)), cocksfoot (Dactylis glomerata (L)) and tall fescue (Festuca arundinacea (Schreb)). Six varieties were used, two for each species. A completely randomized block designed replicated three times was conducted at University of Fort Hare Research Farm during 2014-2015 growing season. The plots were harvested at four-week interval (post emergency) for one year. Biomass yields were measured for fresh forage and dry matter yield. Duplicated samples were then dried, milled and analyzed for chemical and mineral composition (CP, NDF, ADF, and ash, Ca, P, K, Na, Mn, Cu, Zn and Fe) for only winter season. In addition the grasses were ensiled and the silage was analyzed for its fermentation parameters and nutrient content (lactic acid, pH, DM, CP, NDF, ADF, and ash, Ca, P, K, Na, Mn, Cu, Zn and Fe). Biomass results showed significant differences (P < 0.05) between season and varieties. On average Tall fescue varieties Jessup (13741.67 FM kg/ha), Alix (12007.78 FM kg/ ha) and Ryegrass varieties Samson (11597.22 FM kg/ha) and Nui (10591.67 FM kg/ha) had the highest fresh biomass yield. Similarly, Tall fescue varieties Jessup (2833.06 DM kg/ha) and Alix (2708.3 DM kg/ ha) and Ryegrass varieties Samson (2169.44 DM kg/ha) and Nui (2169.67 kg/ha) had the highest dry biomass yield. Throughout the year the average biomass yield was significantly different among species (P< 0.05). During summer and autumn Tall fescue varieties Jessup and Alix gave the highest dry matter yields of 3855.5 to 1977.8 DM kg/ha, and 3877.8 to 1900 DM kg/ha, respectively, and followed by Cocksfoot 2400 DM kg/ha. Ryegrass had the highest dry matter biomass yield in winter (2975 DM kg/ha) and the least in summer (977.75 DM kg/ha). There were no significant (P>0.05) differences on the chemical composition (CP, NDF, ADF, and ash) and mineral composition (Ca, P, K, Na, Mn, Cu, Zn and Fe) of the six varieties. The grass silage results showed significant differences (P< 0.05) among the six varieties for moisture content. Perennial ryegrass variety Nui (66.76 percent) had low moisture content than the other grass silages. The different varieties had no significant effects (P>0.05) on chemical composition (CP, NDF, ADF, and ash) and mineral composition (Ca, P, K, Na, Mn, Cu, Zn and Fe). It is concluded that the biomass production of the six varieties of three grass species was different throughout the year under irrigation hence Ryegrass and Tall fescue are recommended for dairy farmers in the region for all seasons. It can be concluded that there is no difference with respect to fermentation characteristics and nutrient content among the varieties of the grass species.

- Description: It is noticeable that poverty and deprivation exists in all forms in most, if not all, societies. Poverty and destitution have led to the formation and development of rural settlements within an urban context, which is known as informal housing. An example of this is Port Elizabeth’s Walmer Township. Walmer Township is seen to be one of the poorest informal settlements within the Eastern Cape, and has common problems of unemployment, violence, substance abuse, HIV/Aids and illiteracy. These problems adversely affect the community’s living conditions and plummets the society further into a state of destitution. In a last attempt to alleviate poverty among communities, such as the Walmer Township, organizations and external agencies have stepped in to reduce the harmful effects caused by poverty. These include shelters, feeding schemes and job empowerment. However, questions as to whether these organizations actually assist those living in poverty, and how can the organizations or current policy be improved, still exist and are raised regularly today. Thus, the research attempts to investigate the social effects of poverty and how it compromises family units, in order to understand what external organizations are in place to assist these families in destitution, and to come up with recommendations with the view of improving the existing policy

Reproductive biology of important invasive plants in the Eastern Cape Province of South Africa

- Description: Baker’s rule predicts species capable of uniparental reproduction are more likely to establish after long distance dispersal (or introduction in the case of invasive plants), thus the ability to undergo autonomous self-pollination should promote colonization. An investigation into the reproductive biology of eleven invasive species in the Eastern Cape Province of South Africa between 2012 and 2014 showed strong support for Baker’s law. Breeding system results showed evidence of self-compatibility in eight species, ten species were capable of autonomous self-pollination, and only three species showed evidence of varying levels of self-incompatibility. These results provide evdence that autonomous self-pollination occurs more frequently among invasive species, self-compatible species more frequently become invasive compared with self-incompatible species and that autogamous species should have a larger invasive range. Co-opting suitable local pollinators may be problematic for invasive plants, especially those with highly specialized pollination systems. The species investigated appear to be largely independent of pollinators, mostly setting seed in the absence of pollinators. Despite this, all eleven invasive plant species are regularly visited by a variety of generalist pollinators including Apis mellifera, Xylocopa bees and Allodapini species. Pollinators all carried substantial pollen loads, even managing to extract pollen from more specialized plants, such as the poricidal anthers of Solanum species, and frequently came into contact with both anthers and stigmas. Considering most of theses species are capable of autonomous self-pollination, their reliance on pollinators may be low. Even the most self-incompatible species, Passiflora caerulea, appears to have successfully co-opted local pollinators (honeybees and carpenter bees), ensuring successful pollination and seed set. The ability for cross-pollination by local pollinators allows for some degree of genetic variation within invasive plant populations, especially for self-incompatible species. Inadequate pollen deposition by unreliable or inefficient pollinators, or reduced resource availability, can result in pollen limitation. Invasive plant species may be especially susceptible, with three of the plant species investiagted showing possible pollen limitation at the level of seed set, while the remaining nine invasive plant species showed no evidence of pollen limitation in South Africa. The ability to utilize uniparental reproduction (as Baker’s law predicted), and co-opt local pollinators has allowed invasive plants in the Eastern Cape to successfully establish and persist after introduction. Hence, the inclusion of reproductive traits of plants should therefore be included in risk assessments for future plant invaders.

- Description: Baker’s rule predicts species capable of uniparental reproduction are more likely to establish after long distance dispersal (or introduction in the case of invasive plants), thus the ability to undergo autonomous self-pollination should promote colonization. An investigation into the reproductive biology of eleven invasive species in the Eastern Cape Province of South Africa between 2012 and 2014 showed strong support for Baker’s law. Breeding system results showed evidence of self-compatibility in eight species, ten species were capable of autonomous self-pollination, and only three species showed evidence of varying levels of self-incompatibility. These results provide evdence that autonomous self-pollination occurs more frequently among invasive species, self-compatible species more frequently become invasive compared with self-incompatible species and that autogamous species should have a larger invasive range. Co-opting suitable local pollinators may be problematic for invasive plants, especially those with highly specialized pollination systems. The species investigated appear to be largely independent of pollinators, mostly setting seed in the absence of pollinators. Despite this, all eleven invasive plant species are regularly visited by a variety of generalist pollinators including Apis mellifera, Xylocopa bees and Allodapini species. Pollinators all carried substantial pollen loads, even managing to extract pollen from more specialized plants, such as the poricidal anthers of Solanum species, and frequently came into contact with both anthers and stigmas. Considering most of theses species are capable of autonomous self-pollination, their reliance on pollinators may be low. Even the most self-incompatible species, Passiflora caerulea, appears to have successfully co-opted local pollinators (honeybees and carpenter bees), ensuring successful pollination and seed set. The ability for cross-pollination by local pollinators allows for some degree of genetic variation within invasive plant populations, especially for self-incompatible species. Inadequate pollen deposition by unreliable or inefficient pollinators, or reduced resource availability, can result in pollen limitation. Invasive plant species may be especially susceptible, with three of the plant species investiagted showing possible pollen limitation at the level of seed set, while the remaining nine invasive plant species showed no evidence of pollen limitation in South Africa. The ability to utilize uniparental reproduction (as Baker’s law predicted), and co-opt local pollinators has allowed invasive plants in the Eastern Cape to successfully establish and persist after introduction. Hence, the inclusion of reproductive traits of plants should therefore be included in risk assessments for future plant invaders.

- Description: In recent years, proponents of 'green and clean fuel' have argued that the costs of overreliance on fossil fuels could be reduced through transition to biofuels such as bio-ethanol. Global biofuel discourses suggest that any transition to biofuel invariably results in significant benefits, including energy independence, job creation, development of agro-industrial centres at local level and high revenue generations for the state with minimum negative impacts on the environment. With many risks and costs associated with traditional 'dirty' fuels, it is likely that many countries, particularly African countries, will move towards the 'green and clean fuel' alternative. However, until recently research has arguably paid limited attention to the local livelihood impacts related to land acquisition for biofuel development or the policy frameworks required to maximise biofuel benefits. With regards to biofuel benefits, some recent studies suggest that the much bandied potential for greater tax revenue, lowered fuel costs and wealth distribution from biofuel production have all been perverted with relatively little payoff in wage labour opportunities in return (e.g. Richardson, 2010; Wilkinson and Herrera, 2010). Based on work done in Chisumbanje communal lands of Zimbabwe (Thondhlana, 2015), this policy brief highlights the local livelihood impacts of biofuel development and discusses policy implications of the findings. By highlighting the justifications of biofuel development at any cost by the state, the study sheds some light on the conflicts between state interests and local livelihood needs.

In this I am influenced by Kate Bernheimer, who speaks of the “flatness, abstraction, intuitive logic and normalized magic” of traditional fairy tales. A number of stories are set in the places I worked as a newspaper reporter. Here I use my old press reports as starting points for the real or imagined story behind the news – often involving miscommunication, dominance, exploitation, the tension between isolation and belonging, and the nuances of family relationships.

- Description: This thesis conducts a study of literary translation using selected texts by Franz Kafka as translated from German into English in the mid-twentieth century and in the early twenty-first century. This study entails a three-fold orientation, namely: to show the extent of the impact of socio-historical, political and cultural factors on both the translation process and translation product; secondly, it demonstrates the fact that a merging of theoretical principles and practical methods is necessary and possible for the study of literary translations; thirdly, it answers the questions of why the same literary works continue to be retranslated and why every generation of Kafka scholars and readers will need their own translations of his works. This research, furthermore, proposes that the position of literary translation should be elevated since this kind of translation can reveal more about the cultural and linguistic intricacies of the translation process. Seeking to contribute to the broader framework of the translation studies discipline, this thesis also makes a case for translators to reveal their translation process, in the form of notes or prefaces, in order to allow for informed studies of translations. Finally, the research at hand proposes some considerations for further study into literary translations and shows new trends in the sub-field of literary translation which will undoubtedly shift its current nature and call for theoretical and practical applications for more classes of languages.

- Description: This research conducts a Critical Assessment of the Provincial Intervention Outcomes in Makana Local Municipality in the Eastern Cape Province (2012-2014) with the overriding objectives to identify factors which cause unsuccessful Provincial intervention on local government affairs and measure the extent to which these factors played a role in the intervention in Makana Local Municipality and assess the outcomes of Provincial intervention in Makana Local Municipality. The entire research process was guided by the above research objectives and questions that strive to assess the outcomes of Provincial intervention in Makana. The study involved a qualitative research approach: conducting interviews and reviewing the Provincial Strategic Plans 2014, Financial Recover Plans 2014, Makana Annual Financial Statement 2015, Makana Budget Analysis 2014 and the Auditor Generals 2014/15 annual report on Makana. The study identified and defined challenges (factors) that contribute to poor outcomes in Provincial interventions and further identified success factors of Provincial intervention. The extent to which these factors played a role in Makana were then measured, and finally, the outcomes of Provincial intervention in Makana Local Municipality were assessed. The findings of the study indicate that the intervention in Makana Local Municipality has produced stability in the municipality and resulted in a degree of successful outcomes. However, there are priority areas that the municipality still needs to work on in order to make certain that the Makana Local Municipality is fully functional in all the areas that have been identified as priority areas of intervention. The study establish that there are many factors that may lead to Provincial interventions failing in Local government, such as lack of monitoring and evaluation during intervention, lack of commitment by the Province, political interferences and lack of budget or funds to implement the strategic plans. These factors can be prevented in order to assure that Provincial intervention in Local government is successful. The study reveals that proper intervention plans, effective implementations of the strategic plans, coordination and communication between municipal Council, Province and municipal officials, monitoring and evaluation during and after intervention can assist the Province to detect whether the interventions are to be successful. Lastly, the study makes recommendations for both Provincial and Local government.

In the Eastern Cape of Province, South Africa, there is no extensive data reported on Coronary Heart Disease (CHD) determinants and risk factors. The present study sought to assess the risk factors and determinants of CHD. This case (n=50) control (n=50) study matched for sex and age, was conducted among Xhosa adults from rural and semi urban/ township areas of Joe Gqabi District, Eastern Cape Province of South Africa. Non modifiable, environmental, lifestyle, and psychological factors were investigated using univariate analysis and multivariate logistic regression analysis. Depression, alcohol excessive intake, family history of CHD were the CHD univariate risk factors. The independent risk factors of CHD were uncontrolled systolic hypertension (Odds Ratio (OR)=95; 95% Confidence Interval 16.9-128; In front of a multifactorial disease driven by interactions of socio determinants and traditional risk factors, urgent programmes of education, clinical management and health promotion for adequate diet, physical activity, adherence and compliance to medication and are needed to curb epidemic proportions of CVD risk factors.
