- Description: Over the past couple of years there has been a major change in the health-related information available to patients. The modern patient typically researches online before consulting a doctor, leading to more independence for patients regarding their medical care. Doctors continue to play a pivotal role in the medical profession due to their medical education and experience, however, patients are progressively turning to online information to understand their condition. They also check online, following consultation with their doctor, to confirm that the information provided is correct; and frequently ask for advice from people with the same condition. Clearly, patients are changing their normal health seeking behaviour by supplementing what they hear from healthcare professionals through searches for additional sources of information. Unfortunately, online health-related information is not always factual. The misinformation could cause potential problems in the doctor-patient relationship because the doctor has all the information about the patient’s condition, therefore any indication that the patient is trying to undermine the authority of the doctor could be devastating. There is a need for people, or tools, that can support the patient to direct them to high quality information regarding their condition. This concept, known as apomediation, was discussed in detail in this research, as well as the effect on patients. Unfortunately, there is a lack of understanding of the extent to which these tools or people support the apomediation process for patients. This research focused on social networking sites, which is the tool to be used, while the patients were individuals with an autoimmune disease. The purpose of this research is to construct a framework to understand the extent to which social networking sites support apomediation for individuals with autoimmune disease. Research was conducted on existing models and theories that supports apomediation, as well as investigating which social networking sites are available that best support apomediation based on the core features of these sites. The research then focused on the requirements of individuals with autoimmune disease in respect of apomediation. These building blocks led to the construction of a framework artefact 6 that can guide patients on how to determine the extent to which social networking sites support apomediation. An assessment tool was also developed, based on the framework artefact, to evaluate the framework’s effectiveness in executing its designed intention. , Thesis (PhD) -- Faculty of Engineering, Built Environment and Technology, 2023

- Description: Although science education in Namibia receives much attention, learners’ performance is low in subjects such as Physical Sciences. The topic of Forces is among the topics in Physical Sciences where learners perform poorly. The provision of basic education in Namibia faces many challenges. One of these is that many teachers are not fully qualified for teaching the subjects they currently teach. Another (possibly related) challenge is that the majority of teachers in Namibian schools rely heavily on school textbooks when planning their lessons. In addition, learners use school textbooks as learning aids. The textbooks are developed and published in the private sector and based on the national curriculum statements. Quality of education has been amongst the major goals of education in Namibia. For quality assurance purposes, school science textbooks have to undergo a formal evaluation process. School textbooks, especially science textbooks, are multimodal. This means that they are designed with various modes, such as the textual and visual, often used in expressing scientific meanings. Literature reveals the textual and visual as individual modes having their own affordances, however, when integrated in school science textbooks contribute to strengthened meanings. No study published was found in Namibia or elsewhere that focused on analysing the intrasemiotic and intersemiotic sense relations of the textual and visual modes in Namibian school Physical Sciences textbooks. This study therefore aimed at contributing to filling this knowledge gap. The research is a qualitative case study and employed the interpretive paradigm. The selected Physical Sciences textbooks that constitute the data in this study were explored in depth via document analysis. Related textual and visual modes in the Physical Sciences textbooks were analysed in order to help answer the research questions of the study. Systemic Functional Linguistics was employed as the theoretical underpinning for this study. In this study, the sense relations were explored in terms of the sense relation themes which were coded and developed from common features of scientific discourse. The results reveal that scientific knowledge within the textual mode in the topic of Forces is communicated mostly through synonymy and repetition while within the visual mode it is mostly through antonymy, collocation, and synonymy. This contributed to meaning potential in the topic of Forces for the three Physical Sciences textbooks. The results further indicated that the overall cohesion within the textual and visual modes in the topic of Forces is achieved since repetition, which is the most direct form of lexical cohesion together with synonymy, collocation, and antonymy which are aspects of cohesion, occurred most frequently within these modes. This result further indicates that meaning potential in the topic of Forces in the three Physical Sciences textbooks were strengthened. While some sense relations occurred most frequently within individual modes, they were less frequent in other modes and vice versa. This indicates that different modes have different affordances. Finally, it was found that combining the textual and visual modes in the topic of Forces contributes to intersemiotic complementarity being achieved through the sense relations of collocation, hyponymy, and meronymy. , Thesis (MEd) -- Education, Education, 2021
