- Description: This study investigated the potential impacts of several anthropogenic stressors on the movement and survival of African penguins in Algoa Bay, taking into account prey availability and environmental conditions (sea surface temperature and chlorophyll productivity). The primary drive for the study was based on the seismic exploration, which took place in the habitat of the endangered African penguin. The research was also carried out to understand how pelagic fishing and prey availability influence the broader behavioural and mortality aspects of penguins. To achieve this goal, I used monthly beach surveys to assess seabird mortality, admissions of penguins in rehabilitation centres and the monitoring of breeding penguins’ movement at sea through individual GPS tracking. In addition, prey distribution and abundance were monitored with acoustic surveys to assess potential changes in relation anthropogenic stressors. Breeding African penguins did not react dramatically to seismic activities, except on St Croix Island where they changed their foraging direction during the seismic period. There was no evidence of a siginficant increase in African penguin carcasses encountered or strandings along the beaches during the period of seismic activity. However, a sharp increase in encounter rate was recorded soon after seismic operations, which may potentially indicate a delay between the effect of seismic activities on penguin mortality and the encounter of the related carcasses after the operation. However, the impact of seismic surveys on penguins may be long-term rather than short term, and additional studies would be needed to reveal long-term effects of seismic activities, if any. Foraging effort of breeding African penguins increased substantially in the presence of commercial fishing activities within close proximity to the colonies. To a greater extent, at-sea movement patterns and counts of beach cast carcasses were largely influenced by prey availability. Penguins spent more time at sea, traveled longer and covered a larger foraging area during periods of relatvely low pelagic fish abundance. There was also a sharp increase in African penguin mortality during periods of low prey availability in the Bay. However, environmental conditions showed some influence over these interactions.

Penguins spent more time at sea, traveled longer and covered a larger foraging area during periods of relatvely low pelagic fish abundance. There was also a sharp increase in African penguin mortality during periods of low prey availability in the Bay. However, environmental conditions showed some influence over these interactions. For example a red tide event during in period of low prey availability, made it difficult to understand impacts of prey on penguins difficult. Both anthropogenic stressors and environmental conditions influenced African penguins’ behaviour and survival. Due to the worrying trend of African penguins in South Africa for the past few years, all conservation management efforts to increase penguin numbers and limit their mortality are necessary. This study highlights the negative impact of industrial fishing on this Endangered species and the rapid increase in mortality of penguins during times of low prey availability. A network of Marine Protected Areas would certainly increase food availability to African penguins by limiting competition with fisheries, and contribute to increasing the population numbers.

- Description: The focus of this study was on the experiences of a small sample of local women who are HIVpositive and are living in poverty. The researcher was interested in exploring the psychological and social experiences of these women using Interpretive Phenomenological Analysis. This research aimed at giving these women a voice to express their first-hand, personal accounts of living with HIV in poverty. Data was analysed for meaningful units, which were interpreted inductively and hermeneutically, and categorised into super-ordinate themes. Six themes within the participants' experiences of living with HIV were determined, namely: (I) experiences of diagnosis, (2) disclosure experiences, (3) stigma, (4) ARV experiences, (5) experiences of social support and (6) poverty. This research found that after an HIV-positive diagnosis, most women experience a variety of emotional reactions. These reactions however seem to change overtime into positive acceptance of the HIV diagnosis. Most of the women in this study preferred to use partial disclosure than to fully disclose their HJV-positive status openly to families, friends and to their community. Reasons for not using full disclosure included fear of discrimination and stigma, which included a fear of being rejected or being blamed for their status and a fear of losing relationships. It was also evident from the findings that most of the women had experienced stigma directly and therefore partial disclosure was used as a coping mechanism to protect the self from further harm. It was also revealed that stigma not only has a negative impact on disclosure but also on social support and ARV experiences. Because ofHIV-related stigma, lack of social support was a struggle that almost all the women in this study had experienced. Lack of understandings about their medication also had a negative impact of the ARV experiences. Stigmas along with poverty are the major struggles that HIV -positive women have to deal with in their day to day living. The findings of this study reveal a need for further research in this experiential area as well as campaigns and education around issues such as stigma, medication, and emotional difficulties associated with HIV.

To achieve this goal, the following act ions were ta ken: Aliterature study was conducted to identify the best strategies that South African companies could use to manage knowledge workers for optimal benefit; Following the literature review interviews were concluded with key people in the human resource and recruitment industry to determine how a knowledge worker was defined in their organisations as well as to probe what management and human resources strategies were used to manage knowledge workers to their full potential; The interviews, in addition to the literature study, also served as a basis for a survey questionnaire, which was used to probe the views of knowledge workers to determine tools and strategies managers use to manage them. The empirical results from the study showed some concurrence with best strategies suggested from the theoret ical study. In essence, the study revealed that knowledge was well managed in the organisations where the study was conducted and that the knowledge workers were motivated and productive.

- Description: Monitoring unused IP address space by using network telescopes provides a favourable environment for researchers to study and detect malware, worms, denial of service and scanning activities. Research in the field of network telescopes has progressed over the past decade resulting in the development of an increased number of overlapping datasets. Rhodes University's network of telescope sensors has continued to grow with additional network telescopes being brought online. At the time of writing, Rhodes University has a distributed network of five relatively small /24 network telescopes. With five network telescope sensors, this research focuses on comparative and correlation analysis of traffic activity across the network of telescope sensors. To aid summarisation and visualisation techniques, time series' representing time-based traffic activity, are constructed. By employing an iterative experimental process of captured traffic, two natural categories of the five network telescopes are presented. Using the cross- and auto-correlation methods of time series analysis, moderate correlation of traffic activity was achieved between telescope sensors in each category. Weak to moderate correlation was calculated when comparing category A and category B network telescopes' datasets. Results were significantly improved by studying TCP traffic separately. Moderate to strong correlation coefficients in each category were calculated when using TCP traffic only. UDP traffic analysis showed weaker correlation between sensors, however the uniformity of ICMP traffic showed correlation of traffic activity across all sensors. The results confirmed the visual observation of traffic relativity in telescope sensors within the same category and quantitatively analysed the correlation of network telescopes' traffic activity.

- Description: The focus of this study is to explore three key aspects of learners’ multiplicative proficiency: the nature of learners’ conceptual understanding of multiplication, the nature of learners’ numeracy dispositions (in the context of learning multiplication), and the relationship between conceptual understanding and productive dispositions in the context of multiplication. The study used a qualitative case study approach to gather rich data in relation to these. In the study a purposively selected sample of six Grade 4 learners was used from the same school: two high, two average, and two low performers. Kilpatrick, Swafford, and Findell (2001) define conceptual understanding as a functional grasp of mathematical ideas and its significant indicator is being able to represent mathematical situations in different ways and knowing how different representations can be useful for different purposes. They then refer to productive disposition as the ‘tendency to see sense in mathematics, to perceive it as both useful and worthwhile, to believe that steady effort in learning mathematics pays off, and to see oneself as an effective learner and doer of mathematics’ (p.131). Individual interviews were conducted using Wright, et al.’s (2006) instrument for exploring the nature of students’ conceptual understanding of multiplication. Wright, et al. (2006) argue that the topics of multiplication and division build on the students’ knowledge of addition and subtraction, and also multiplication and division provide foundational knowledge for topics such as fractions, ratios, proportion and percentage, all of which are core and essential areas of mathematical learning typically addressed in the primary or elementary grades. Researchers agree that learners have to be exposed to various strategies so that they are able to see that there is a difference between additive reasoning and multiplicative reasoning. In order to classify learners’ conceptual understanding of multiplication an analysis of the data was done and learners were allocated levels according to the Wright, et al. (2006) levels of achievement. For the classification of learner dispositions, the data was analysed in terms of the elements of productive disposition as defined by Kilpatrick, et al. (2001) and Carr and Claxton (2002). The key findings of the study indicate that for conceptual understanding most of the learners depended on using concrete materials in solving multiplication and they also used basic strategies and methods. The findings for productive dispositions were that most of the learners saw themselves as competent in doing multiplication but the aspect of sense making and steady effort was less developed. The findings for the relationship between conceptual understanding and productive disposition were that both strands have a mutual relationship in which one helped the other to develop.

- Description: The alignment of information systems with organisational objectives and strategies is crucial to the efficient performance of any organisation. There is a growing focus on the effectiveness of management and evidence-based decision making in public institutions in South Africa. The Eastern Cape Department of Social Development and Special Programmes (ECDSD) implemented a Social Development Information Management System (SDIMS), which is an information system that supports various functions performed by the Department. While SDMIS provides large amounts of valuable information, it still has much ground to cover in terms of fully meeting the Department’s information needs. There is an increasing demand for information to inform decision making with regards to priority setting, resource usage, monitoring the impact of the Department’s intervention programmes, and monitoring the progress of the Department’s strategic goals. The main purpose of this study was to analyse the extent to which MIS is utilised in the Eastern Cape Department of Social Development and Special Programmes and to make recommendations for the alignment of MIS with organisational objectives in order to achieve these objectives. Furthermore, the study intends to investigate the extent to which the information needs of managers are considered in designing and providing information. The objectives of the study are, firstly, to analyse the current state of MIS utilisation in the Department. Secondly, to evaluate the utilisation of information provided by the MIS unit for decision making, and, thirdly, to make recommendations on how to improve MIS utilisation. Qualitative approach techniques were utilised to collect data for the study. Research questionnaires were distributed to thirty respondents. Semi-structured interviews were conducted with seven interviewees out of a target number of ten. The response rate was 68 percent and this was considered as adequate for scientific analysis and reporting. The study produced the following research findings: Mainly, the MIS users believe that they understand MIS and its capabilities, and have received training on how to use the system. The quality of information provided by MIS is mostly complete and largely meets user requirements and expectations. MIS information is for the most part accurate and comprehensive enough to expedite decision-making. Although MIS largely meets user requirements and expectations in terms of completeness, accuracy and reliability, the study indicates that it still falls short in integrating information from other sources, which include government transversal systems such as the Basic Accounting System (BAS) and the Personnel Salary System (PERSAL). MIS information is mostly available and easy to access, but occasionally not timely. This is mostly caused by the unavailability of real-time information synchronisation between MIS and other government systems. In light of the above findings, the researcher recommends that: There is still more to be done in order to continuously inform and train users on the latest MIS capability developments in the form of awareness workshops, contact and remote support, and through internal news bulletins. The Department needs to work with other government entities that are custodians of transversal systems in finding a solution to the creation of real-time integration of MIS with other external sources of information. Even though the level of MIS utilisation is not too much of a concern, the Department needs to ensure that users of information are kept up to date with new MIS reporting capabilities so as not to underutilise the system. It is therefore recommended that the Department ensure that information is more often reviewed and reports are customised to meet the ever-changing needs of the Department.

While SDMIS provides large amounts of valuable information, it still has much ground to cover in terms of fully meeting the Department’s information needs. There is an increasing demand for information to inform decision making with regards to priority setting, resource usage, monitoring the impact of the Department’s intervention programmes, and monitoring the progress of the Department’s strategic goals. The main purpose of this study was to analyse the extent to which MIS is utilised in the Eastern Cape Department of Social Development and Special Programmes and to make recommendations for the alignment of MIS with organisational objectives in order to achieve these objectives. Furthermore, the study intends to investigate the extent to which the information needs of managers are considered in designing and providing information. The objectives of the study are, firstly, to analyse the current state of MIS utilisation in the Department. Secondly, to evaluate the utilisation of information provided by the MIS unit for decision making, and, thirdly, to make recommendations on how to improve MIS utilisation. Qualitative approach techniques were utilised to collect data for the study. Research questionnaires were distributed to thirty respondents. Semi-structured interviews were conducted with seven interviewees out of a target number of ten. The response rate was 68 percent and this was considered as adequate for scientific analysis and reporting. The study produced the following research findings: Mainly, the MIS users believe that they understand MIS and its capabilities, and have received training on how to use the system. The quality of information provided by MIS is mostly complete and largely meets user requirements and expectations. MIS information is for the most part accurate and comprehensive enough to expedite decision-making. Although MIS largely meets user requirements and expectations in terms of completeness, accuracy and reliability, the study indicates that it still falls short in integrating information from other sources, which include government transversal systems such as the Basic Accounting System (BAS) and the Personnel Salary System (PERSAL). MIS information is mostly available and easy to access, but occasionally not timely. This is mostly caused by the unavailability of real-time information synchronisation between MIS and other government systems. In light of the above findings, the researcher recommends that: There is still more to be done in order to continuously inform and train users on the latest MIS capability developments in the form of awareness workshops, contact and remote support, and through internal news bulletins. The Department needs to work with other government entities that are custodians of transversal systems in finding a solution to the creation of real-time integration of MIS with other external sources of information. Even though the level of MIS utilisation is not too much of a concern, the Department needs to ensure that users of information are kept up to date with new MIS reporting capabilities so as not to underutilise the system. It is therefore recommended that the Department ensure that information is more often reviewed and reports are customised to meet the ever-changing needs of the Department.

- Description: Abalone, Haliotis midae, farmers in South Africa that feed formulated diets reported a periodic drop in abalone growth during periods of increased gonad development. A large drop in abalone biomass was noticed after presumed spawning events. This study was aimed to determine the effect of diet and sex-sorting on gonad development in abalone. Experiments were conducted on a commercial abalone farm from July 2012 to the end of June 2013. Isonitrogenous and isoenergetic diets were formulated with two protein sources. A fishmeal and soybean meal (S-diet) diet and a fishmeal only (F-diet) diet were fed to abalone (50 - 70 g abalone⁻¹) over 12 months. Weight and length gain, gonad bulk index (GBI), visceral index (%) and meat mass index (%) were determined monthly and seasonally. A histological study on the female gonads was conducted. This study also included an experiment to test the effect of sex-sorting (70 - 80 g abalone⁻¹) on growth and body composition with treatments including males (M), females (F) and equal numbers of males and females (MF). Weight gain and length gain were faster in S-diet-fed abalone (RM-ANOVA, F ₍₁, ₁₆₎ = 7.77, p = 0.01; F ₍₁, ₆₉₎ = 49.9, p < 0.001, respectively). Gonad development was significantly affected by the inclusion of soybean meal with S-diet-fed abalone showing higher GBI-values than F-diet-fed abalone (RM-ANOVA, F ₍₁, ₃₃)= 16.22, p = 0.0003). Male abalone had higher GBI-values than females (RM-ANOVA, F ₍₁, ₃₃₎ = 39.87, p < 0.0001). There was no significant difference in average feed conversion ratio (FCR) between diets over time (RM-ANOVA, F ₍₁, ₂₁₎ = 0.008, p = 0.97). However, average FCR-values were significantly highest between November 2012 and March 2013, the presumed spawning season. The visceral mass (gut and gonad) as a proportion of whole mass (visceral index, %) was significantly higher in abalone fed the S-diet (RM-ANOVA; F ₍₁, ₆₉₎ = 68.06, p < 0.0001). There was no difference in meat mass index (%) between diets for both male and female abalone (RM-ANOVA; F ₍₇, ₂₄₈₎ = 0.80, p = 0.60; F ₍₇, ₂₄₁₎ = 1.7, p = 0.11,respectively). Meat mass index significantly decreased from September 2012 to February 2013 coinciding with the period of high GBI-values. The distribution of oocyte maturity stages differed between diets. The majority of oocytes within S-diet-fed abalone were fully mature stage 8 oocytes compared to a majority of stage 7 oocytes in F-diet-fed abalone. Histology corroborated peaks in GBI-values for abalone fed both diets. There was no significant difference in growth, GBI, visceral index (%) and meat mass index (%) between abalone sorted into monosex and mixed-sex populations. Thus, the presence of the opposite sex did not have an effect on growth and gonad mass in H. midae. The phytoestrogens daidzin, glycitin, genistin, daidzein, glycitein and genistein were present in soybean meal and only traceable amounts were found in the F-diet. This study provided evidence that soybean meal present in formulated feed affected growth and gonad development in H.midae. The difference in the distribution of the maturity stages of oocytes was affected by diet. Sex-sorting abalone into monosex and mixed-sex populations had no influence on weight and length gain and gonad development.

- Description: The focus of the study was two-fold, firstly to determine the effect of age on the capacity of manual materials handling workers and secondly to determine the effect of increasing task mechanisation on the workers’ responses to task demands. The first component of this study, namely Part I, 101 male and 12 female ‘unskilled’ manual workers – of various ages – from a brick manufacturing industry were assessed. Anthropometric, health and strength factors were measured to improve the understanding of the South African manual worker capacity and more specifically, the effect of age on this capacity. Data collection was done between 7.30am and 9.30am in a laboratory-type setting on-site. Anthropometric characteristics (including body mass index, waist to hip ratio, waist circumference and body fat percentage) provided information on the state of obesity and the impact of age in the South African context. Linked to this, the health factors (including blood pressure, resting heart rate and a self-reported questionnaire) provide an extra snapshot of the disease profile in South Africa, and could potentially influence other capacity factors. Isometric strength capacities (of eight different areas, namely: back, leg, bicep, shoulder, pinch, pinch and pull) demonstrated whether South African manual workers show the same decline in strength with aging as seen in industrially advanced countries. The second component of the study, Part II, was performed in situ and measured the workers’ responses to task demands of three brick palletising tasks, one manual (n=21) and two with increasing mechanisation (n=12 each). Spinal kinematics, joint forces and working heart rate were assessed on normal work days during a 30-lift duration and body discomfort measures were taken at the start, middle and end of the work-shift. Spinal kinematics were measured dynamically using a lumbar motion monitor, whereas the spinal forces were estimated using the three dimensional static strength prediction program. The worker capacity results showed that waist to hip ratio, waist circumference and body fat percentage increased significantly with aging, whereas body mass index was not affected by age. All body morphology values were within ‘normal’ ranges. Although diastolic blood pressure increased significantly with age, systolic was not affected significantly by age. Both groups, however, showed an increasing prevalence of hypertension with aging. There were no significant changes in resting heart rate with aging, with a range of 66 bt.min⁻¹ to 74.86 bt.min⁻¹, therefore within normal ranges. Of the strength factors, age only affected shoulder and push strength significantly: Showing a decrease in shoulder strength from 49.89 kgF to 39.91 kgF in the men aged 20-29 to the 50-59 respectively and an increase in push strength from men aged 30-39 and 40-49 to those aged 50-59. Part II results revealed highly frequent lift rates and large degrees of sagittal flexion and lateral bending in all three tasks. These postures adopted for long durations are likely to lead to the development of musculoskeletal disorders. Heart rates of workers from the three tasks were significantly different and heart rates for two tasks were above the recommended 110 bt.min⁻¹. Similarly the body discomfort ratings of the three tasks differed, although a common trend was seen in that lower back pain was the most commonly reported area of discomfort in all tasks. South African manual materials handling males did not show the same responses to aging as men from industrially advanced countries, calling for further research into these differences. Due to the high risks of the three tasks assessed, future research and interventions are required to reduce the risk of injury in the assessed tasks.

- Description: As the number of computing devices connected to the Internet increases and the Internet itself becomes more pervasive, so does the opportunity for criminals to use these devices in cybercrimes. Supporting the increase in cybercrime is the growth and maturity of the digital underground economy with strong links to its more visible and physical counterpart. The digital underground economy provides software and related services to equip the entrepreneurial cybercriminal with the appropriate skills and required tools. Financial malware, particularly the capability for injection of code into web browsers, has become one of the more profitable cybercrime tool sets due to its versatility and adaptability when targeting clients of institutions with an online presence, both in and outside of the financial industry. There are numerous families of financial malware available for use, with perhaps the most prevalent being Zeus and SpyEye. Criminals create (or purchase) and grow botnets of computing devices infected with financial malware that has been configured to attack clients of certain websites. In the research data set there are 483 configuration files containing approximately 40 000 webinjects that were captured from various financial malware botnets between October 2010 and June 2012. They were processed and analysed to determine the methods used by criminals to defraud either the user of the computing device, or the institution of which the user is a client. The configuration files contain the injection code that is executed in the web browser to create a surrogate interface, which is then used by the criminal to interact with the user and institution in order to commit fraud. Demographics on the captured data set are presented and case studies are documented based on the various methods used to defraud and bypass financial security controls across multiple industries. The case studies cover techniques used in social engineering, bypassing security controls and automated transfers.

- Description: The majority of learners in South Africa are not native speakers of English, yet English is the dominant language of learning and teaching (LoLT). South African teachers, therefore, have the challenge of ensuring that their learners' literacy skills in English are adequately developed so as to facilitate learning in other curricular areas. This study investigated the way in which two Grade 5 teachers employed at different primary schools in the Eastern Cape province of South Africa taught writing to their English first additional language (EFAL) learners. English is the LoLT at both schools. A qualitative interpretive approach was used to identify factors that shape the ways these teachers handle the teaching of writing. The theoretical framework was informed by Borg's model of teacher cognition (2003) Shulman's conception of teacher knowledge (1987). Data collection methods consisted of interviews, classroom observations and document analysis. In-depth interviews, comprising two semi-structured interviews, two post-lesson informal conversational interviews and one stimulated recall interview were conducted with each teacher. Five of each teacher's writing lessons were observed and audio and video recorded. Samples of learners' written work were also collected. Analysis of the data reveals that the two teachers' beliefs, their experiences as learners themselves and subsequently as teachers, impacted on their pedagogy, as did other contextual factors (including the support they received from subject advisors, time management, and the number and range of learners in their classrooms). It was found that both teachers focused primarily on ensuring that their learners completed their written work so that it could be marked and graded in response to demands from their superiors, rather than on engaging deeply with the processes of writing (brainstorming, drafting, revising etc). Not only does this run counter to the writing pedagogy recommended in the Curriculum and Assessment Policy Statements (CAPS), but it also denies learners the scaffolding needed to help them develop the self-regulation skills needed to become independent writers. These findings demonstrate the need for assisting teachers to shift away from focusing only on learners' performance (testing and grading) towards a stronger emphasis on the process of writing. This would require that teachers develop a deeper understanding of the process/genre approaches to teaching writing advocated by CAPS.

In realising this right, the State is obliged to provide financial and human resources in a manner that will transform society as a whole and deliver a better life for all citizens. The human resources in the main refer to educators. Education is one of key priorities of the present government to the extent that President Zuma has instructed that a presidential commission be established to look into the conditions of service of public servants and in particular that of educators. The International Labour Organisation (ILO) has proposed the Decent Work Country Programmes to help countries align their policies with the international goal of the achievement of Decent Work for all. South Africa has done a lot of work in this regard; however the main challenge remains with the implementation and acceptance of such policies by the major stakeholders especially the trade unions. This treatise investigates the impact of the Decent Work Agenda (DWA) on the job security and provisioning of educators in South Africa. It also explores the conditions of service of temporary educators and those educators who are teaching in the rural areas under extremely difficult conditions in comparison with their counterparts in urban areas. This treatise also examines the status of social dialogue in the education sector and the impact of same on collective bargaining. This treatise recommends that the utilisation of the services of temporary educators need to be regulated to address the continuous extension of temporary contracts that is impacting negatively on job security. It also suggests that urgent measures in the form of norms and standards be determined to improve the working conditions of educators who are teaching in rural areas under very difficult circumstances.

The principle of complementarity : a critical analysis of Article 17 of the Rome Statute from an African perspective

- Description: This thesis attempts to address perennial concerns, mostly raised in some quarters in Africa, pertaining to the development of the complementarity regime established by the Rome Statute of the International Criminal Court. It grapples with a very important question, whether the principle of complementarity, embodied in article 17 of the Rome Statute, was formulated and is being applied by the ICC in a manner that upholds the ideals and theories upon which the regime was founded. The principle of complementarity is designed to mediate the imperatives of State sovereignty and a legitimate international criminal justice system. Essentially, complementarity gives States latitude to try genocide, crimes against humanity, war crimes and aggression nationally, with the ICC only intervening where States are either unable or unwilling to prosecute genuinely. Africa constitutes the biggest regional block of membership to the Rome Statute, however, over the years; support for the ICC on the African continent has waned. It has been argued in some quarters that the ICC is anti-African and that it has interpreted and applied complementarity in a manner that diminishes State sovereignty. The thesis argues that this tension may also be due to textual deficiencies inherent within the Rome Statute, in the provisions that embody this principle. It therefore examines complementarity from a theoretical perspective to provide a comprehensive account of the system contemplated by the drafters of the Rome Statute. In this regard, the thesis argues for expansion of States’ ability at the national level to deal with international crimes without compromising international criminal justice processes or threatening State sovereignty. This is suggested as a way of relieving the tension that has characterised the relationship between African States and the ICC. The thesis further sketches out some of the complexities inherent in the modalities through which the Court may exercise its complementary jurisdiction, particularly within the African continent, given that legal systems in most African countries are particularly weak. It thus dissects the provisions that outline the principle of complementarity in tandem with the Court’s interpretation and application of complementarity in practice. Furthermore, through an exploratory survey of the referral of the Situation in Uganda, and the ICC Prosecutor’s proprio motu investigation of the Situation in Kenya, the thesis illustrates how a positive approach to complementarity can help establish a healthy cooperative synergy between the ICC and States, thereby promoting a functional expeditious criminal justice system. This will go a long way towards assuaging State’s fears that the ICC merely pays lip service to complementarity and arbitrarily supersedes national jurisdiction.

- Description: This study involves using methyllithium to synthesize Fischer carbene complexes as precursors for metal templated α,β-unsaturated complexes with potential as acceptors in the Baylis Hillman reaction as well as in Dötz benzannulation. Fischer carbene complexes contain low oxidation state metal centers, are electrophilic in nature and are stabilized by π-donating substituents such as alkoxy and amino groups. The increased electron withdrawing nature of the metal carbonyl moiety was expected to improve the rates of reaction compared to organic carbonyls. Four Fischer carbenes were synthesized via nucleophilic addition of MeLi to chromium and tungsten hexacarbonyl at low temperatures followed by alkylation using either a Meerwein salt (Me₃OBF₄) to give the desired Fischer metal methyl methoxy carbenes or Et₄NBr/alkylhalide to make the corresponding ethoxy and allyloxy carbenes. Characterization was by means of ¹³C NMR, ¹H NMR, and IR. In silico studies were carried out looking at the effect of substituents on the carbene bond. Synthesis of α,β-unsaturated complexes was effected via the aldol condensation route and found to be unfavorable using enolizable aldehydes, although the use of two aryl aldehydes resulted in successful preparation of two α,β-unsaturated complexes. Difficulty in the purification of these complexes hindered their full characterization. Computational studies looked at the effect of substituents on the system as well as variation of the metal from Cr to Mo and W. Synthesis of Baylis Hillman adducts using α,β-unsaturated complexes as acceptors was unsuccessful due to the ease of product oxidization. One potential product was obtained in its crude form although purification was not possible due to oxidation. Computational studies suggested that the oxygen on the ligand negatively impacts the stability of these Fischer carbene derived Baylis Hillman adducts promoting intramolecular oxidation of the metal. The α,β-unsaturated complexes and Baylis Hillman adducts were considered to be candidates to undergo Dötz benzannulation methodology. The use of the α,β-unsaturated complexes in this reaction was generally unsuccessful, both in the microwave and in conventional reflux conditions. Computational studies of these compounds were carried out to facilitate understanding of their stability and configuration.

- Description: This research is premised on the understanding that alternative forms of media emerge to deal with specific ideological projects and, as such, must be seen as satisfying a specific need at a specific point in time. Using the case of a weekly newspaper, The Southern Star which was in circulation from January 2012 to June 2012, this study sought to understand the factors that led to the establishment of the newspaper, what it sought to achieve, how it went about putting that into practice, its message in relation to debates emanating from the ‘Matabeleland Question’ and also the factors that led to the its collapse. In order to address my research questions, I adopted a two stage research design qualitative content analysis and semi structured in depth interviews. In locating the study within the qualitative epistemic understanding of research, it was clear from the qualitative content analysis of 13 editions of the publication and in depth interviews held with 15 respondents that the newspaper was set up with the aim of serving a marginalised section of the population (in this instance the Ndebele) by providing them with a platform to articulate issues affecting them. It also sought to ‘speak’ the ‘unspoken’ within the mainstream media by focusing on Matabeleland identity politics. It achieved this by creating content around the Gukurahundi genocide, Matabeleland development, Matabeleland history and Matabeleland heroes. The newspaper also sought to emancipate the people from the South by advocated for social, cultural, economic and political justice as a resolution to the ‘Matabeleland Question’. However, the newspaper failed to sustain operations due to lack of advertising revenue. As a result of the constraining political environment in which the newspaper operated, potential advertisers were afraid of placing advertisements in the newspaper because of the nature of the content produced, which in view of Zimbabwe’s rival ethnic history, could easily be labelled ethnically divisive. Also, being a new player in the market worked to their disadvantage as prospective advertisers opted to place their adverts in “tried and tested” publications (Zimpapers and Alpha Media Holdings). Additionally, because of poor management, roles were not clearly defined and hence the newspaper failed to operate as a business enterprise. As noted during interviews with junior reporters, there was little or no experience at management level. The paper lacked a coordinated circulation strategy and from inception, was never officially launched, which resulted in the failure to reach significant audiences.

- Description: In this study, 400 presumptive Enterococcus isolates previously recovered from Kat River and Fort Beaufort Abstraction water dam were subjected to molecular confirmation and pathotyping. Two hundred and seventy-four (68%) of these isolates were confirmed to be enterococci species. Confirmations studies were polymerase chain reaction (PCR) based, using enterococci specific primers targeting the tuf gene. The confirmed enterococci isolates were further differentiated into their pathotypes, the targets of which were: E. faecalis, E. avium, E. hirae, E. casseliflavarus and E. gallinarum using well documented species specific primer sequences. E. faecalis accounted for 20% of the isolates, followed by E. avium (16%), E. hirae (13%), E. casseliflavarus (5%) and E. gallinarum (3%). Furthermore, all the confirmed isolates were analysed for antibiotic susceptibilities using a panel of nine different antibiotics, namely vancomycin, linezolid, ciprofloxacin, ampicillin, gentamicin, chloramphenicol, tetracycline, erythromycin, penicillin, and those that were resistant were assayed for the presence of relevant antibiotic resistance genes. All the 274 isolates were found to harbour vanA resistance gene confirming their phenotypic resistance to the vancomycin. Similarly, 60% (109/180) of the isolates showed phenotypic resistance to erythromycin which was further confirmed by the presence of ermA genes in these isolates. The presence of antibiotic resistant bacteria in surface waters poses a risk to public health.

- Description: In efforts to alleviate poverty in South Africa, the democratic Government has since 1994 implemented various programs and policies that aim to alleviate income poverty through stimulating employment, developing skills and improving service delivery. One of these policies is Local Economic Development (LED). LED has been adopted by the South African government as a shift from the purely service oriented to developmental local government. The Constitution of the Republic of South Africa, 1996 commits local government to the promotion of social and economic development. Section 152 (1) (b) of the Constitution 1996 further states that local government should ensure that services are delivered in a sustainable manner. The Local Economic Development as a strategy that is aimed at stimulating economic activities at the local sphere has been hailed for its participative nature with communities. Local communities cease to be mere recipients of services; rather they become actively involved in their own economic development. The main objectives of the study were to investigate the effectiveness of the implementation of LED strategies in Nkonkobe Municipality, to find out how Nkonkobe Municipality communities perceive municipal LED efforts and initiatives for poverty alleviation, to determine the challenges which are faced by Nkonkobe Municipality in terms of implementing its LED strategies and to make recommendations on how LED can be strengthened, supported and or improved in Nkonkobe Municipality. Qualitative and quantitative methods of data collection and analysis were used in this study. The study findings suggest that there is still a lot to be done in order to implement LED in Nkonkobe Municipality. There are a number of recommendations made by the researcher to assist the municipality.
