  • Description: Software based routing simulators suffer from large simulation host requirements and are prone to slow downs because of resource limitations, as well as context switching due to user space to kernel space requests. Furthermore, hardware based simulations do not scale with the passing of time as their available resources are set at the time of manufacture. This research aims to provide a software based, scalable solution to network simulation. It aims to achieve this by a Linux kernel-based solution, through insertion of a custom kernel module. This will reduce the number of context switches by eliminating the user space context requirement, and serve to be highly compatible with any host that can run the Linux kernel. Through careful consideration in data structure choice and software component design, this routing simulator achieved results of over 7 Gbps of throughput over multiple simulated node hops on consumer hardware. Alongside this throughput, this routing simulator also brings to light scalability and the ability to instantiate and simulate networks in excess of 1 million routing nodes within 1 GB of system memory

  • Description: This study explored the methods available for measuring corporate sustainability and created an instrument to measure corporate sustainability in the Nelson Mandela Bay (NMB) automotive manufacturing sector. The instrument was created based on three components of sustainability which are environment, society and economy. The study went a step further and added a fourth dimension, current trends to design a measuring instrument. The instrument was then applied on participating companies and further refined to improve it. A total of 16 multi-dimensional indicators to measure corporate sustainability were created and applied to 12 companies in the automotive manufacturing sector. The indicators were used to create a composite corporate sustainability index which can be used to compare the corporate sustainability performance of companies. These indicators were created based on theoretical research and fist hand experience observing the automotive manufacturing sector in the NMB. The indicators were applied to companies as a pilot to test whether they are feasible. Following this, the indicators were refined, improved and applied to more companies to measure corporate sustainability performance. The results of the study were the measuring instrument created, the creation of a composite index as well as the application of the instrument on 12 companies to determine whether the instrument was refined enough to detect differences in the corporate sustainability performance of companies. The results are discussed and further recommendations are made for improvements in the creation and application of the instrument to measure corporate sustainability in the NMB automotive manufacturing sector.

  • Description: Poor communities already face severe challenges in meeting their basic needs, whether because of poor income opportunities, inadequate service delivery, or degraded ecosystems that can no longer support the needs of people. Non profit organisations who provide support for development are also challenged by financial restrictions and social and political structures that prevent or limit project development. Climate change is understood to have the most severe impact on the most vulnerable communities and sectors of communities by reducing the availability and accessibility of basic resources such as water, food and energy, impacting severely on human health and wellbeing, and further reducing the capacity of ecosystems to support livelihoods. This will add a layer of significant new complications to the ability of poor communities to maintain or improve standards of living, and further challenge non profit organisations that support such communitiesAnticipatory adaptation to climate change can reduce some of the impacts of climate change, and also address some key development stresses. This thesis aims to provide a framework that is relevant for supporting adaptation to climate change within the context of resource poor communities in a developing country. Non profit organisations and donor agencies could support success and autonomy in adaptation processes by making provision for locally defined understanding of adaptation, and locally determined processes and programmes. This can be taken further into implementation of programming that addresses local short term development priorities alongside, or as part of long term adaptation work. The research followed a number of steps involving a multitude of techniques including literature review, interviews, a survey, consultation with an expert group, further consultation with stakeholders, and a final electronic review. Its outcome is a strategy that can be used to support climate change adaptation in resource poor communities. A definition for adaptation is proposed as an interpretation of adaptation that is relevant in this context. The intended end goal of adaptation as defined in this research is a better form of development that : supports a harmonious and respectful relationship between humans and their natural resource base; averts further destructive global change or at the very least prevents it from becoming unmanageable; and manages the impacts of past and ongoing destructive change so that there is lowest possible loss of natural, human, or cultural resources. The term transformative adaptation emerged from the research processes to describe adaptation to climate change that concurrently addresses development challenges, is grounded in community development aspirations, integrates programming work across multiple thematic areas and approaches, and addresses the causes of climate change within adaptation interventions. The following broad guidelines are used to inform programming within the framework of transformative adaptation : Human communities are faced with an enormous challenge resulting from global change and sociopolitical injustices; Well planned anticipatory adaptation can limit exposure and vulnerability to at least some of the projected impacts of climate change; Adaptation to climate change incorporates a reduction of vulnerability to underlying development stresses, alongside a reduction of vulnerability to specific climate change stresses; Existing development work forms the foundation for adaptation interventions, acknowledging the interdependence of social, natural and economic systems and the need to maintain their health; Adaptation decision making is community based, and acknowledges that resource poor communities are best placed to establish their own development needs, drive implementation of interventions in own spaces, and identify own limits to adaptation; Adaptation work incorporates mitigation objectives so that the causes of climate change are addressed as part of the strategy for coping with climate change; Adaptation programming acknowledges the strong interlinkages between, and integrates work across, the thematic areas of water security, food sovereignty, energy security, land security, human wellbeing and livelihood diversity; Adaptation uses a broad set of approaches that spans research, knowledge sharing, advocacy, and investment in technology and infrastructure; There is flexibility in project design and implementation to allow room for experimentation with new concepts, and also to change design as knowledge, understanding, and geophysical, biophysical and sociopolitical conditions change.

  • Description: The resurgence of the polio virus in Nigeria following vaccine rejections poses a severe threat to the total worldwide eradication of polio. Vaccine refusals are a huge problem in Nigeria, especially in the North, which accounts for about 60 percent of polio cases in 2013. These refusals were informed by claims that polio vaccines contained anti-fertility properties that were designed by the ‘West’ to reduce the Muslim population. These claims and subsequent vaccine rejections culminated in the killing of health workers during an immunisation exercise in February 2013. This study is an analysis of the coverage of the polio eradication controversy by two newspapers- Punch and Daily Trust, following the killings of the health workers. Daily Trust is situated in Northern Nigeria, while Punch is situated in the South. The choice of these newspapers is based on the argument by Ayodele (1988) and Omenugha (2004) that the Nigerian press has been accused of escalating tension in the country because they view many aspects of the Nigerian reality from the lenses of religious, political and cultural prejudices. Because it is a text-based study, the chosen research method is Fairclough’s (1995) model of Critical Discourse Analysis (CDA), following a preliminary thematic content analysis. In addition to Fairclough’s model, the study employs textual analytic tools such as narrative analysis and rhetoric/argumentative analysis. The selected texts, which comprise editorials and news stories are analysed based on the themes identified during the thematic content analysis. The study concludes that while the two newspapers differ in their locations and stylistic approach to news, they are similar in their coverage of the polio eradication crisis. They both side with the Federal Government and help perpetuate the South versus North animosity thereby ignoring the intricacies involved in the polio eradication controversy.

  • Description: This study was conducted in order to understand Grade 10 Life Science teachers’ perceptions and experiences of teaching human reproduction topics in the Ohangwena political region in the northern part of Namibia. It also explored how the culture of the majority of the inhabitants of Ohangwena region who are Oshiwambo speaking impacts the teaching of human reproduction topics. The study was prompted by the fact that the Grade 10 Life Science syllabus requires learners to learn details of human reproduction although in Oshiwambo culture such things are not discussed openly. And this section has proven to be one of the poorly answered sections in the Grade 10 national examinations. A total of thirty five (35) Grade 10 Life Science teachers participated in this study. It is a qualitative case study underpinned by an interpretive paradigm. The unit of analysis for this study was teachers’ perceptions and experiences of teaching the topic of human reproduction. Data were generated through document analysis, questionnaires and tape recorded semi-structured interviews. Such data were analysed inductively by sorting them into categories and then into emerging themes. Categories included teachers’ views and experiences of being taught and teaching human reproduction, how culture influenced the manner in which teaching and learning of human reproduction takes place as stated in the socio-cultural theory, and how teachers of different gender perceived and experienced the teaching of human reproduction according to the feminist standpoint theory. The emerging themes were colour coded and then developed into analytical statements. Data triangulation, member checking, and follow up interviews ensured data validity and trustworthiness. This study revealed that the cultural belief of the Owambo people that prohibits adults to talk to children about things related to sex because it encourages them to practice sex is still strong among individuals in the community including teachers themselves. As a result, teachers are not comfortable with teaching human reproduction topics. From the findings, it is recommended that teachers should be empowered to teach Life Science, specifically human reproduction topics, with confidence. Furthermore, parents should be made aware of the importance of including human reproduction topics in the school curriculum so that they can motivate their children to study it with an open mind.

  • Description: The new curriculum in Namibia has introduced a new approach to teaching and learning requiring teachers to make use of learners’ prior everyday knowledge (PEK) including indigenous knowledge (IK) and practical work/activities. It further emphasizes some variations in teaching methods such as; the use of analogies, the use of mind maps, and so forth with the aim to actively involve learners in the learning process and develop skills to solve global challenges. The emphasis is on understanding of knowledge, skills and the will to use them appropriately throughout their lives. The main aim of this study was to understand and document how Biology teachers mediate learning of the topic respiration. Informed by an interpretive paradigm, a qualitative case study was conducted at two secondary schools in the Kunene region. The participants were selected using a convenience sampling. Data were gathered using three main sources, namely, documents, semi-structured interview questions which culminated into a questionnaire and observations. Triangulation was thus used to give credibility, objectivity and validity to the interpretation of the data. Data analysis in this case study involved a multi-stage process of organizing, coding and categorizing, synthesizing and summarizing. The audio recorded lessons were transcribed into text and I analyzed data using a colour coding technique by segmenting and labelling text to identify descriptions and broad themes in the data. Vygotsky’s Mediation of Learning and Social Constructivism in conjunction with Shulman’s Pedagogical Content Knowledge (PCK) informed the data analysis process. Teacher-learner interactions were the main theme for mediation of learning (social constructivist perspective), hence during analysis I paid more attention to moments where interactions evolved and I used PCK to gain insights in teaching and instructional strategies used by teachers. The findings of this study revealed that: 1) teachers endeavor to use a variety of teaching methods such as the use of a mind maps and question and answer method. Learners were keen to ask questions in order to understand this topic. 2) The study also revealed that a lack of practical activities is one of the challenges teachers are faced with. Based on my research findings, I therefore suggest that there is a need for continuous professional development of biology teachers and capacity building in order to improve both their content and pedagogical content knowledge.

Understanding how grade 11 Biology teachers mediate learning of the topic on transpiration

  • Description: This study emerged in response to the poor performance in Biology at my school. The Ministry of Education Biology (NSSCO) Examiners’ report (2011) for Paper 3 indicates that learners proved to have difficulties in designing experiments, failed to give a distinction between apparatus and the experiment. The 2012 Examiners’ report on transpiration also highlights that learners were not exposed to practical work. Furthermore, the 2012 report notes that teachers need to work on their learners’ drawing and spelling of terms. It is against this backdrop that a qualitative study was conducted at a school in Oshikoto, using a sample of two teachers. The study’s purpose was to investigate how grade 11 Biology teachers mediate learning of the topic on transpiration. Social Constructivism and Pedagogical Content Knowledge formed the framework used to analyse data gathered from document analysis, interviews and observations. The study findings were that teachers use locally available material for demonstration during practical work, elicit prior knowledge, use a chalkboard to summarise content to learners, and use a question and answer method as strategies in mediating learning on transpiration. In addition, the teachers use homework, scaffolding activities, group work, code-switching, feedback on activities, as well as the use of analogies. Despite efforts by participant teachers to mediate learning of transpiration, shortage of equipment for conducting practical work, poor English proficiency among teachers and learners, and little emphasis on graphing by the syllabus proved to be barriers to their efforts. This study thus recommends that in order to improve on teaching transpiration, teachers need to co-plan lessons, conduct practical work, code-switch during lessons, ensure effective assessment, and include lessons on graphing. Furthermore, teachers need continued training on how to teach transpiration.

  • Description: This research focused on an investigation of the pedagogy and strategies used by Grade 11 Life Sciences teachers when mediating Biodiversity concepts with English second language learners. My interest in this investigation was triggered by the Examiners’ Reports for Life Sciences from 2009 to 2012 which consistently noted learner challenges in answering, interpreting and analysing questions during exams. The reports highlighted learners’ lack of understanding of the questions which led to them providing irrelevant information in their exam scripts. These reports claimed that challenges experienced by these learners could be attributed to language issues experienced by English second language learners. Influenced by these reports, a qualitative case study of two Senior Secondary schools in East London, Eastern Cape South Africa was conducted. Underpinned by an interpretive paradigm and driven by the desire to achieve an in-depth understanding of the case under study, three phases of information gathering were followed. The first phase was that of gathering information through document analysis. Documents were analysed to gain insights and understanding of the issue before conducting interviews. The next phase was that of gathering information through semi-structured interviews followed by classroom observations. Findings from these observations were verified through stimulated recall interviews which provided clarity on the intentionality of choosing a certain method and strategy over another when assisting learners in making meaning of biodiversity concepts. The main findings of this study are that factors which limit learner understanding of biodiversity concepts are a result of a combination of factors such as failure to interpret questions, spelling problems which alter meaning of concepts and an inability to make distinctions among closely related concepts within the topic of Biodiversity. Responding to these factors, teachers demonstrated knowledge of a variety of teaching strategies to support learners. The choice of teaching strategies seemed to be guided by their experiences as well as the challenges they often encounter. Furthermore, teachers’ reflections on their practice provided opportunities for them to identify strengths and limitations of their choice of strategies and possibilities for improvement. It was also noted that factors such as large class sizes, gaps in content knowledge and a lack of detail in chalkboard summary limited the effectiveness of their teaching strategies. The study recommends that: • Teacher-learner ratio needs to be considered for effective support; • There is still a need to capacitate educators in environmental education. In-service training should focus on developing teacher understanding of foundational knowledge in life sciences; and • Teachers need to improve their chalkboard summary skills to increase the level of support that could be provided by comprehensive chalkboard summary through the elaboration of ideas

  • Description: The National Curriculum of Education was implemented with the broad view of including all learners as laid out in the document Toward Education for All. The curriculum emphasised that the topic distillation should be studied. According to the Examiners Reports, the topic distillation is one of the topics where learners face difficulties in the Namibian Senior Secondary Certificate Ordinary (NSSCO) examination Grade 12. This led me to do research on understanding how Physical Science teachers mediate the topic distillation in Namibia specifically in the Kavango region. The study was carried out at two rural schools with two teachers teaching Grade 11. The community member who I asked to demonstrate the making of Kashipembe was also a participant during this study. Kashipembe is a local cultural brew alcohol beverage commonly made in the Kavango East and West Regions of Namibia, which was used as a learning context in this research study. The study used a qualitative case study underpinned by an interpretive paradigm. Data was generated through the use of document analysis, semi-structured interviews, stimulated recall interviews, lesson observations, brainstorming and practical demonstration of making Kashipembe. These different methods of data gathering were used with the aim of triangulating and validating the data. Therefore, my theoretical framework adopted Vygotsky’s (1986) mediation of learning, social constructivism and pedagogical content knowledge according to Shulman’s (1986) theory. The emergent themes were identified inductively and they were colour coded. These themes were later developed into analytic statements which were used in the study. The findings indicate that the use of community knowledge and experience during the teaching of scientific concepts like distillation is important. These findings can also be used by the practising teachers to make their teaching more effective in the curriculums where distillation is included. Therefore, the Namibian curriculum developers need to include this community knowledge in the curriculum to make it easier for the learners to make sense of the topic distillation.

  • Description: The pervasive presence of cellphones in the lives of urban young people around the globe has led to widespread research to evaluate the impact that this device has on young people’s overall psychosocial development. This relationship is often characterised as “addictive”. This research study presents a unique South African youth perspective in a field of research that is predominantly conducted in the United States, Europe and Asia. It explores the relationship that students (ages 18–21) at Rhodes University have with their cellphones in order to understand how this device informs their experience of social participation online and offline. Central to the design of this study is a “social media detox” which involved the research participants volunteering to restrict their social media and cellphone use for an agreed-upon period of time. The study employs interpretative phenomenological analysis (IPA) to uncover key themes from in-depth interviews before and after the detox. Eight respondents were interviewed twice; once before and once after their detox. This study provides insights into the integral role of a cellphone as reported from a young adult’s perspective. Communicating on social media platforms using a cellphone has become normalised among this age-group and the respondents described how the cellphone feels like “a part of you”. Unlike interacting face-to-face which is potentially awkward and involves effort, socialising on a cellphone offers the respondents a sense of companionship, control and instant access to their peer groups. The respondents in this study seemed unaware of their own agency in social situations until their participation in the social media detox. By participating in this study, the participants became more aware of how their cellphone use influences social behaviour, both online and offline. The study proposes that the term “addiction” undermines the positive association young people have with their cellphones. Instead, this study suggests that “social fitness” would be a more relevant construct through which to encourage and support young people to exercise agency in their social lives. This exploratory study raises new questions for researchers, programme developers and educators to take up in future studies and programme development

  • Description: This thesis focuses on land reform in post-apartheid South Africa and specifically on land redistribution, as one of the main pillars of land reform. There have been many studies undertaken on land redistribution in South Africa and these studies offer deep criticisms of the prevailing land redistribution model (a market-led, but state-assisted model) and the ways in which this model has failed to meaningfully address colonial dispossession of land. Further, studies have focused on post-redistribution livelihoods of farmers and the many challenges they face. One significant gap in the prevailing literature is a sustained focus on the state itself, and particularly questions around policy formation and implementation processes pertaining to land redistribution. Delving into policy processes is invariably a difficult task because outsider access to intra-state processes is fraught with problems. But a full account of land redistribution in South Africa demands sensitivity to processes internal to the state. Because of this, it is hoped that this thesis makes a contribution to the existing South African land redistribution literature. In pursuing the thesis objective, I undertook research amongst farmers on selected redistributed farms outside Grahamstown in the Eastern Cape, as well as engaging with both current and former state land officials. Based on the evidence, it is clear that the policy process around land in South Africa is a complex and convoluted process marked not only by consensus-making and combined activities but also by tensions and conflicts. This, I would argue, is the norm with regard to what states do and how they work.

  • Description: In 1994, racial domination in the form of apartheid ended in South Africa and the first postapartheid government was elected through a non-racial and democratic franchise. The new government inherited an entrenched system of racial inequality as well as widespread poverty amongst the formerly oppressed population, and it sought to address these challenges through policies of redistribution based on a new progressive constitution which emphasised the realisation of socio-economic rights. At the same time, and despite its redistributive measures, the post-apartheid government has pursued a macro-economic strategy with pronounced neoliberal dimensions. One of its critical redistributive measures focuses on social assistance to poor blacks, and this has entailed the construction and expansion of a massive social grant system including the child support grant which is received by millions of black South Africans on a monthly basis. The objective of this thesis is to examine and understand the livelihoods of child support grant recipients (or caregivers) in the context of conditions of extreme vulnerability marked by poverty. It does so by focusing on the small town of Riebeek East located in the Eastern Cape Province of South Africa. Though undoubtedly child support grant caregivers are victims of poverty, the thesis demonstrates that they are not without agency. They exist in structural conditions of vulnerability and poverty, but they nevertheless seek to manoeuvre and negotiate their way in and through their conditions of existence. This does not necessarily alleviate their poverty in any significant manner but it does show evidence of reflexivity, decision-making and responsibility in the pursuit of livelihood practices and outcomes. In making this argument, I draw upon the mega-theory of Margaret Archer (specifically, her morphogenetic approach) and the more middle-level perspective of the Sustainable Livelihoods Framework. Beyond contributing to the prevailing academic literature on the child support grant in South Africa, this thesis also hopefully makes a small contribution to controversies about structure and agency within sociology.

  • Description: Workplace bullying is a modern day problem which employers cannot afford to ignore. The impact on both the business (or organisation) and individual is of such a nature that research is needed to understand it better and to determine the extent to which it is present in the business or organisation. Research thus far covered the prevalence, consequences and causes of bullying in the organisation. Various methods to counteract and prevent it have been investigated, but with reference to the South African context knowledge is lacking. This study focuses on workplace bullying in SMMEs as very little research has been done in this field. The purpose of this study is to be able to provide a framework for managers as to how to deal, prevent and minimise workplace bullying in SMMEs of South Africa. A convenient sample was selected and information was gathered by means of a questionnaire. A quantitative study was executed and the prevalence of bullying in the SMMEs was established and a number of independent variables were tested. The independent variables researched were managerial training, awareness training, a corporate anti-bullying policy, risk assessment and mediation. The main findings were that bullying in SMMEs is indeed prevalent, but that the independent variables did not deliver significant correlations. The practical implications for managers are that strategies and tools used in larger organisations are not applicable in SMMEs. The workplace environment of the SMME is unique and different methods and tools must be identified and applied in combatting workplace bullying. The contribution of this study is that managers in South Africa across the broad industrial spectrum must realise that bullying is prevalent and that corporate policies and measures must be put in place to address it. It can no longer be ignored and further research on the subject must be encouraged.

  • Description: The focus of this paper is to emphasize the importance for every employer to avoid unfair discrimination during the recruitment process and to value diversity in the workplace. This is not only a legal requirement, but also gives an employer the best chance of getting the right person for the job. It is crucial to understand that job applicants are mostly people that employer’s do not actually employ, but might be able to make an unfair discrimination claim against the employer if the claimant believes he/she was not selected for a job because the employer discriminated against them unlawfully in the recruitment process. When writing the job description and a person specification, the employer should state clearly what tasks the person will have to execute and what skills will be needed for the job. Job descriptions should accurately describe the genuine essential duties and inherent requirements of the job. Personnel specifications should accurately describe the relevant, non-discriminatory and objectively justifiable requirements to be met by the post-holder. Specifications should not have any requirements that are not directly related to the job and it is important for employers to provide evidence that each recruitment and screening practice is job-related and consistent with business necessity. Employers are advised to devise and implement recruitment procedures and guidelines for all staff and applicants involved in the process of recruitment and to ensure that these incorporate the principles of the organisation’s equal opportunity principles. Employers should administer recruitment and other selection procedures without regard to race, colour, national origin, sex, religion, age and disability. Even though South Africa is now governed by a new democratic order, historical workplace inequalities still need to be addressed. Not only compelled to redress inequalities by the Constitution, the South African government was motivated by the International Labour Organisation (ILO) to enact laws that would prohibit discrimination and promote the economic advancement of the majority. Recruitment tests or selection procedures must be job-related and its results appropriate for the employer’s purpose. If a recruitment procedure screens out a protected group, the employer should determine whether there is an equally effective alternative selection procedure that has less adverse impact and, if so, adopt the alternative procedure. The justification of discrimination in recruitment practices and affirmative action is only meaningful if it is targeted towards particular aims. One of the more important defences against unfair discrimination in the workplace is the general fairness defence. The general fairness defence is considered to be an applicable defence based on fairness in situations where the two statutory exceptions do not apply. This means than when one looks at the concept of unfair discrimination it implies that discrimination may be justified in certain circumstances Legislation prohibits discrimination on various grounds especially throughout the process of recruitment and selection. There are limited exceptions to the general principle that it is unlawful to use gender, race, religion or sexual orientation as a criterion in the recruitment process. These exceptions are known as genuine occupational qualifications and the specifications for jobs should be carefully examined to ensure that there are no factors contained that are indirectly discriminatory. Focus must be placed on avoiding indirect discrimination in job factors. In the early stages of the recruitment process, an employee specification should be written that describes the type of person the employer seeks to be appointed in terms of qualifications, experience, skills and personal attributes. The imposition of inappropriate or unsuccessfully high standards or criteria may indirectly discriminate against people from a particular minority or racial group or religion. Employees must have the necessary skills to demand employment equity status especially where a designated employer does not have sufficient affirmative action employees and is obliged to rectify the situation. However, this does not mean that affirmative action applicants must be chosen above non-affirmative action employees. The principle of reversed discrimination stands firm if the motivation for appointing a particular person is based on a genuine desire to promote diversity, to apply affirmative action and to increase the numbers of people from a disadvantaged group in employment, or to create a more balanced workforce.

  • Description: This topic deals with unfair labour practice relating to promotion and will focus mainly on the public education sector. The Labour Relations Act of 1956 and 1995, with respect to the concept of unfair labour practice, will be analysed. It is through this discussion that one appreciates how the concept of unfair labour practices has evolved in South African law. An attempt is made to define promotion and in this regard reference is made to cases decided upon by the Commission for Conciliation, Mediation and Arbitration (CCMA) or the Labour Court (LC). Furthermore, promotion is defined within the context of public education and applicable legislation. Due regard must be to the employment relationship between the employer and the employee as well as compare the current employee’s job with the job applied to. Unfair conduct by the employer will be discussed within the context of promotion. The prerogative of the employer will be discussed with reference to case law and that discussion will include an analysis of various principles with regard to procedural and substantive fairness. Various remedies provided for in dispute resolution mechanism in line with the provisions of the Labour Relations Act 66 of 1995 and relevant case laws will also be discussed. The last chapter deals with how to strike a balance between employee rights (that is educators) and the rights of learners, in the context of promotion disputes. In this regard reference to case laws will be made. In general the topic will deal with unfair labour practice, definition of promotion including promotion of educators, unfair conduct of the employer, onus of proof, remedies and striking the balance between the rights of the learners and educators.

  • Description: Alcohol use among university students is a worldwide social and clinical reality. Understanding and addressing this phenomena is an imperative recognised by the government of South Africa and its Higher Education institutions, where student drinking has a plethora of negative consequences. This study builds on the work of Young and de Klerk (2012) with Rhodes University students by adding drinking motives to their findings of demographic correlates. The motivational model of alcohol use (Cox & Klinger, 1988) posits that drinking motives are a proximal predictor of alcohol use. The model further delineates four drinking motives (social, enhancement, coping, and conformity) which are hypothesized to lead to phenomenological distinct patterns of alcohol use. An online survey method was utilized to collect data and a representative sample of 501 students participated. Descriptive and inferential statistics were computed to address five research questions: (1) to establishing the current alcohol use trend; (2) to investigate the demographic factors associated with alcohol use; (3) to describe students‘ drinking motives; (4) to explore the correlates of drinking motives; and, finally, the primary aim was (5) to investigate whether students‘ drinking motives predicted alcohol use when controlling for the effects of descriptive drinking norms and demographic variables. The results indicate that 68.5% of participants currently consume alcohol, and 51.0 % of these drinking students consume five or more drinks during a drinking session. 20.7 % of the drinking students used alcohol at the harmful or alcohol dependent levels. Increased alcohol use was associated more with males, undergraduates, early onset drinkers, more disposable income, and students‘ perceptions of their peers‘ drinking. Students endorsed enhancement motives marginally more than social motives, followed by coping and conformity motives. Males, early onset drinkers, black students, and at risk (of alcohol use disorders) students endorsed more motives, especially social and enhancement motives. Of primary concern was the role of drinking motives on alcohol use after controlling for the effects of descriptive drinking norms. The four block hierarchical regression model which was run explained 38% of the variance in alcohol use. Drinking motives, particularly enhancement motives, displayed a statistically significant impact on alcohol use adding 11% to the variance. Additionally, age of alcohol use onset, monthly pocket money, age, and gender predicted alcohol use separately. The results of this study indicate that alcohol use has multi-factorial influences. Of note, the results confirmed the motivational model of alcohol use by indicating that alcohol use is partially motivational and that drinking behaviour is not a unitary phenomenon but instead it represents heterogeneity based on the affective change individuals anticipate to gain by drinking. The high binging rate (51%) among this sample may speak to the greater endorsement of enhancement motives, which have been shown in previous studies to be associated with heavy drinking. Enhancement motives are attempts to attain positive affect which, due to the psychoactive properties of alcohol, require greater consumption and intoxication. Additionally, as a result of the greater quantities of alcohol, individuals who drink for enhancement motives would be more prone to alcohol consequences. The results suggest that a multi-level intervention framework targeting individual students, the university community, and the surrounding community, is indicated. Furthermore, intervention may be tailored-made to address specific drinking motives.

  • Description: This thesis reports on a collaborative action research case study with Grade 8 learners in a rural high school in Fort Beaufort District, Eastern Cape, South Africa. The goals of the case study were firstly, to understand best practices for promoting extensive reading using a classroom library, and secondly, to use these insights to put an extensive reading programme in place with a view to improving my practice as a language teacher and to gain better understanding of ways of enhancing my Grade 8 learners’ literacy skills. The following qualitative methods were used to collect data: observation, semi-structured interviews, class discussion, questionnaires, journal reflections and document analysis. Analysis of data involved identification of emerging themes and patterns. The findings suggest that the strategies used in the extensive reading intervention improved my learners’ levels of engagement with reading. Putting these strategies into practice, and reflecting critically on how to refine them helped enrich my own professional insight and development in relation to the implementation of extensive reading programmes. Since action research is usually designed in spirals of action, this research serves as a first spiral and a foundation upon which to build second and subsequent spirals (which do not form part of this research). The study highlighted the fact that certain challenges that emerged (for example, shortage of books at the learners’ level, and a lack of parental cooperation) need to be addressed in a second spiral of intervention. The study further suggested that the implementation of effective extensive reading programmes by teachers in the middle and upper phases of secondary schooling requires further investigation.

  • Description: The main objective of the study was to ascertain the presence of the identified critical success factors for lean sustainability in a chemical manufacturing company in Port Elizabeth. The critical success factors that formed part of the research included leadership involvement and commitment, management involvement and commitment, employee engagement and organisational culture. The methodology used was one of a positivistic approach. A questionnaire was utilized and the responses were analyzed using various statistical methods. Based on the results from the analysis, recommendations and conclusions could be drawn. The inferential results of the study indicated that all the critical success factors identified for this study were present within the organisation. However, there were still a large percentage of respondents that remained neutral across all the questions which could indicate reasons why previous attempts in lean implementation failed. The recommendations provided were based on the findings of the study. An implementation strategy was identified and outlined. This strategy and recommendations will assist in providing a sound platform for a sustainable lean initiative within the organisation.

Using risk mitigation approaches to define the requirements for software escrow

  • Description: Two or more parties entering into a contract for service or goods may make use of an escrow of the funds for payment to enable trust in the contract. In such an event the documents or financial instruments, the object(s) in escrow, are held in trust by a trusted third party (escrow provider) until the specified conditions are fulfilled. In the scenario of software escrow, the object of escrow is typically the source code, and the specified release conditions usually address potential scenarios wherein the software provider becomes unable to continue providing services (such as due to bankruptcy or a change in services provided, etc.) The subject of software escrow is not well documented in the academic body of work, with the largest information sources, active commentary and supporting papers provided by commercial software escrow providers, both in South Africa and abroad. This work maps the software escrow topic onto the King III compliance framework in South Africa. This is of value since any users of bespoke developed applications may require extended professional assistance to align with the King III guidelines. The supporting risk assessment model developed in this work will serve as a tool to evaluate and motivate for software escrow agreements. It will also provide an overview of the various escrow agreement types and will transfer the focus to the value proposition that they each hold. Initial research has indicated that current awareness of software escrow in industry is still very low. This was evidenced by the significant number of approached specialists that declined to participate in the survey due to their own admitted inexperience in applying the discipline of software escrow within their companies. Moreover, the participants that contributed to the research indicated that they only required software escrow for medium to highly critical applications. This proved the value of assessing the various risk factors that bespoke software development introduces, as well as the risk mitigation options available, through tools such as escrow, to reduce the actual and residual risk to a manageable level.
