Description: Time-resolved infrared-stimulated luminescence (TR-IRSL) from feldspar samples is of importance in the field of luminescence dating, since it provides information on the luminescence mechanism in these materials. In this paper we present new analytical equations which can be used to analyze TR-IRSL signals, both during and after short infrared stimulation pulses. The equations are developed using a recently proposed kinetic model, which describes localized electronic recombination via tunneling between trapped electrons and recombination centers in luminescent materials. Recombination is assumed to take place from the excited state of the trapped electron to the nearest-neighbor center within a random distribution of luminescence recombination centers. Different possibilities are examined within the model, depending on the relative importance of electron de-excitation and recombination. The equations are applied to experimental TR-IRSL data of natural feldspars, and good agreement is found between experimental and modeling results.

Description: The incidence of increased life span as well as a lack of care for older persons, gave rise to the South African Older persons Act (Act No 13 of 2006), which guides society in how our older persons should be treated. This Act also provides a clear indication of the expectations of caring for older persons within communities and families. Many older persons people rely on the relationships they have with their children in their golden years, to be fulfilling and loving. This study therefore aimed to explore the experiences of older persons and their adult children on maintaining positive relationships in order for the relationship to be most beneficial for both older persons and their adult children. The quality of relationships between adult children and older persons according to Newby (2010) can ease participation of adult children in the lives of older persons. This study was conducted from a qualitative research perspective that is exploratory, descriptive and contextual in nature. The exploratory-descriptive design allowed the researcher to understand the topic by using a narrative strategy of inquiry. A non-probability purposive sampling method was applied to identify five older persons as well as the adult children of these older persons who are retirees of an automotive company in South Africa. Individual, semi-structured face to face interviews were conducted with older persons as well as with at least one of their adult children who did not reside with them. Thematic data analysis technique was used to analyse the data collected. The study is viewed as significant in enhancing the understanding of satisfying and caring relationships between older persons and their adult children in order to add to the body of existing knowledge in social gerontology and to improve direct social work practice with older persons.

Description: The great demand for video services on the Internet is one contributing factor that led telecom companies to search for solutions to deliver innovative video services, using the different access technologies managed by them and leveraging the capacity of enforcing Quality of Service (QoS). One part of the solution was an infrastructure that guarantees QoS for these services, in the form of the IP Multimedia Subsystem (IMS) framework. The IMS framework was developed for delivering innovative multimedia services, but IMS alone does not provide the required services. This has led to further work in the area of multimedia service architectures. One noteworthy architecture is IPTV. IPTV is more than what its name implies, as it allows the development of various innovative video-oriented services and not just tv. When IPTV was introduced, many thought that it would bring back the revenue loss that telecom companies experienced to over-the-top (OTT) service providers. However, despite all its promises, the IPTV implementation has not shown as wide an uptake as one would expect. Although there could be various reasons for the slow penetration of IPTV, one reason could be the technical challenge that IPTV poses to service developers. One of the main reasons for the embarking of the research reported in this thesis was to identify and select free and open source software (FOSS) based platforms and augment them for easy development and deployment of video-oriented services. The thesis motivated how the IPTV architecture, with some modification, can be a good architecture to develop innovative video-oriented services. For a better understanding and investigate the issues of video-oriented service development on different platforms, we followed an incremental and iterative prototyping method. As a result, various video-oriented services were first developed and implementation-related issues were analyzed. This has helped us to identify problems that service developers face, including the requirement to utilize a number of protocols to develop an IPTV-based video-oriented service and the lack of a platform that provides a consistent programming interface to implement them all. The process also helped us to identify new uses cases through the process. As part of our selection process, we found that the Mobicents service development platform can be used as the basis for a good service development and deployment environment for video-oriented services. Mobicents is a Java-based service delivery platform for quick development, deployment and management of next generation network applications. Mobicents is a good choice because it provides a consistent programming interface and supports the various protocols needed in a consistent manner or an easy way to include the support for them. We used Mobicents to compose the environment that developers can use to build video-oriented services. Specifically we developed components and service building blocks that service developer can use to develop various innovative video-oriented services. During our research, we also identified various issues with regard to support from streaming servers in general and open source streaming servers in particular and also with the protocol they use. Specifically, we identified issues with Real Time Streaming Protocol (RTSP), a protocol specified as the media control protocol in the IPTV specification, and made proposals for solving them. We developed an RSTP proxy to augment the features lacking in the current streaming servers and implemented some of the features we proposed in it.

Description: Economies aim to expand over time, which always implies the need for increased energy availability in support of this growth. Governments can use their procurement of energy generation to further enhance the benefit to their economies via certain policy tools. One such tool is Local Content Requirements (LCR) where procurement of a good dictates that a certain value has to be sourced locally. The argument for this tool is that spend is localised and manufacturing, as well as job creation, can be stimulated due to industry establishing in the host economy. However, this practice is distortionary in effect and it does not create a fair playing field for global trade. Furthermore, if the local content definition is weak, or open to manipulation, the goals of such a policy may not be achieved at all. This study looked into the local content requirements of South Africa’s Renewable Energy Independent Power Producer Procurement Programme (REIPPPP) and measured the impact of this policy on the renewable energy sector in general. It was found that, in order to implement a policy such as local content, the host economy had to have certain pre-existing conditions in order to avoid any negative welfare effects. Due to SA not holding all supportive pre-conditions for supporting local content policy, the impact and effect of LCRs has not been optimal and it has not been found to be a sustainable mechanism to continue using into the future indefinitely. The pricing of renewable energy was also found to be higher due to local content and such pricing is passed on to the energy consumer. Therefore, the net welfare impact created for South Africa is diminished in exchange for the creation of jobs and manufacturing, but due to the unsustainability and potential manipulation of the system the country is not maximising the welfare potential from the REIPPPP as it should. It was found that SA renewable energy resources do exist and the logistics infrastructure is strong, providing good potential for investment into renewable energy projects. The demand created by the REIPPPP provided a good market, but there was uncertainty in the long term planning and stability. So, from a market perspective this could be further enhanced. Government had created a sufficient platform for investment, but areas of development such as clusters, R&D and skills training would create a better support environment for LCR policy and strict monitoring of this would also be required to prevent any manipulation. The use of LCRs increases project costs and risk, which is passed onto the energy consumers, but this could be reduced if local goods were more readily available at the right price and at the right quality and quantity. Focus on clusters would once again assist in this regard as independent power producers (IPPs) and engineering procurement and construction (EPC) entities would be able to source components and goods locally in a more cost-effective manner. As the LCRs currently stand in the REIPPPP, it would seem that South Africa is making renewable energy more expensive and although it is argued that this is done for the benefit of creating a new industry and jobs, these are not sustainable and so the current LCR policy will only create short term benefits.

Description: The economic crisis and prior recession made a huge dent in many industries. Companies want a cheaper manufactured product with same quality to satisfy the customer in order be competitive yet profitable. Shatterprufe is a company that produces automotive glass. The company has a vast number of products and experience short production run lengths because of its order intake from customers. These short production run lengths require accurate setup to have a repeatable and stable process. An incorrect setup will produce a high scrap rate on production runs. Glass being very brittle and machining it incorrectly results in flaws, breakages or edge stresses that lead to latter process failures. The scoring operation of glass is key to achieve good edge quality to prevent such defects. The correct tools and machine parameters influence good edge quality during the setup procedure. Due to the process having many variables it is difficult to have a stable process and a repeatable stable process. This research will analyse the tool, parameters of the tool and machine parameters to achieve best edge quality and correlating these parameters that will lead to a repeatable stable process. An experimental analysis was conducted on 2.1mm and 2.5mm thick glass. These thicknesses are used predominantly at Shatterprufe automotive glass manufacturing company. The first sample and last sample was analysed during a production run. An average production run length is 36 pieces of glass. The edge quality was seen under a microscope and the fissure depth was measured. To achieve ideal edge quality, the fissure depth must be 15-20% deep of the glass thickness. A fissure is a crack propagated during the scoring of glass. A carbide wheel is used to score the glass. The carbide wheel parameters were varied being the wheel angle and wheel diameter. A 145 degree-4.1mm wheel, 145degree-5.6mm wheel and a 155 degree- 4.1mm wheel was used. The following relationships where observed being the wheel diameter and fissure depth. An increase in wheel diameter resulted in an increase in fissure depth but decreases the wheel life as the wheel becomes blunt. There was inconsistency on fissure depth with the larger diameter wheel. An increased in wheel angle from 145 degree to 155 degree promoted flaws in the glass. Larger wheel angles work better on glass thicknesses of 4-5mm as currently used in the Shatterprufe Struandale Company. An investigation on pressure variation in the pneumatic system was analysed using a pressure transmitter. The pressure transmitter measured the pressure per second versus the set pressure and recorded this data on a data logger. There was no pressure variation in the pneumatic system that can influence poor glass edge quality. A load cell analysis will investigate the physical applied pressure on the glass versus the set pressure. This analysis was to determine the relationship between set versus actual on the glass. It will indicate any mechanical fault. A mechanical fault could be a loose coupling or linkage that can influence the fissure depth. A direct proportional relationship was achieved between the set pressure versus the load cell readings. This indicates no mechanical fault on the system.

Description: Technology enables progress for individuals and organisations; however, adopting technology may not always be simple. Cloud computing technology has revolutionised how one consumes IT. Governments too can leverage the advantages of adopting cloud computing. A review of the literature reveals a gap in research on the adoption of cloud computing by the South African public sector. Limited research has been done on the topic of cloud computing and none of them are from a quantitative perspective. This study set out to answer the question, “What is the extent (current state, benefits, barriers and readiness levels) of the adoption of cloud computing by the South Africa public sector?” The study is of much value to the public sector of South Africa and other countries and organisations wanting to understand what to consider when adopting cloud computing. The study used a survey research strategy that was exploratory in nature. The sample comprised government CIO’s and government Senior IT management. Questionnaires were sent via a web link and 51 responses were completed. The results revealed that more than half of the South African public sector has adopted cloud computing; however there is a lack of visibility of government initiatives that promote cloud computing. The study shows that public organisations that have adopted cloud computing significantly perceive more benefits of cloud computing than organisations that are yet to adopt. The Technology Organisation Environment (TOE) framework tested the barriers to adoption, revealing areas of concern that are limiting successful cloud computing adoption and adoption rates. The study uncovers a timeline for further cloud computing adoption in the South African public sector.

Description: The concepts underlying this treatise develop from an observation of contemporary society’s inherent reliance on technology, its growing popularity as an information exchange mechanism and Africa’s lack of connection to it’s foundation, the internet. Human interaction with digital technology, supported by the internet, has created a new social culture which manifests meaning through visual and virtual cues. These make reference to place and are experienced as real and individual, relating to theories such as Heidegger’s imagined place (Heidegger 1971). In order to enhance Southern Africa’s connection with the global network of the internet, the design of an Internet Server Facility will bridge previously under-utilized international lines into the country at Port Elizabeth engaging with the existing infrastructural system. At this point of connection the infrastructural zone impedes the extension of a public environment. The design seeks to challenge the conception of the highway infrastructure in Port Elizabeth as objects that dehumanise space. It intends to emphasise structure and building as a set of processes or systems able to work together to enable not only the functional aspects of data infrastructure, but also respond to the urban fabric providing a multitude of spatial environments that engage with everyday human activity. Investigations of the previous impact of infrastructure which has been layered onto the edge of Port Elizabeth’s historical core, reveal the stripping of it’s place-making qualities over time, resulting in an urban wasteland. In considering the placement of an infrastructural system, an existing vacant space that forms part of the current infrastructure is more appropriate than using up other urban spaces. In its response, the system would need to respond to its urban environment in a way that infrastructure has previously failed to do in this area, due to its position adjacent to the CBD. For this reason the design is concerned with the urban rejuvenation of the scarred landscape and a design strategy for the development of a contemporary digital infrastructural system, capable of not only being a non-evasive to the urban environment but also a catalyst in the creation of physical and digital place-making in the public realm.

Description: This action research study explored and analysed the role of teacher corrective feedback in helping Grade 8 learners to improve the accuracy of their written English as their second language. Therefore, the goals of this study were to examine the kind of language errors my grade 8 learners’ made in their writing, to find out whether these errors could be categorized linguistically, and to determine if they were errors, mistakes or lapses. The study further analysed how learners responded to my feedback, and also determined which feedback strategies worked best to help my learners deal with their errors, mistakes or lapses. This study set out to look at six learners from one Grade 8 class of 40 learners. The data were gathered from six written essay scripts, and each learner wrote four essay draft revisions. The learners’ written essays were analysed by means of checklists in order to identify the types and patterns of errors made. Errors such as punctuation, past tense verbs, spelling and vocabulary were identified, analysed and categorized to provide insights into reasons underlying the instances in which they were committed. The findings of this study showed that factors underlying learners’ written errors included mother-tongue interference, overgeneralization, fossilization, translation, lack of concentration, and carelessness. The findings further showed that corrective feedback on learners’ draft revisions provided them with extensive exposure and practice in English, enabled them to internalize language rules, and reduced the tendency to commit errors in their writing. The findings further suggest that procedures such as multiple-draft activities, indirect feedback, direct feedback, focused corrective feedback, error correction and written feedback with explicit corrective comments improved their levels of writing. Furthermore, putting these procedures into practice and reflecting critically on how to apply them helped enrich my own teaching practices and development in relation to the provision of corrective feedback to improve accuracy in learners’ writing. The findings are discussed in the context of the related literature. This study should be read by ESL teacher-trainers, ESL teachers, ESL student-teachers and ESL learners/students in general.

Description: Since the inception of the student supernumerary status, both globally and in South Africa, nursing and midwifery educators have been concerned about the clinical competencies of their students. Student clinical competency levels in South Africa are critical to midwifery practice, especially as most litigation against the Department of Health in South Africa concerns negligence in midwifery practice. In addition, the litigations mostly involve newly qualified midwives, thus suggesting a link with practice competency levels. Several challenges exist in the academic and practice environments regarding student learning, practice and clinical preparedness. Lack of support during clinical placement and a lack of facilities for use during clinical practice modules are among these challenges. Some students, due to the challenges they face with clinical learning and practice, fail to meet the practical competencies for examination entry requirements. Consequently, some of these students have to repeat the year or exit the programme. The current study sought to identify how to assist midwifery educators in their activities to prepare students for clinical placement readiness. The first objective of the study was to explore and describe the perceptions of midwifery educators regarding the need for additional measures to enhance the clinical preparedness of basic midwifery students before they are allocated to the clinical areas. The second objective sought to make recommendations that would further assist the midwifery educators to clinically prepare midwifery students before being allocated and placed in different clinical areas. A qualitative, explorative, descriptive and contextual research design was used for the study and the study was conducted at a nursing college in the Eastern Cape Province from August 2014 to January 2016. The research population consisted of midwifery educators at a nursing college and a purposive sampling technique was used guided by set criteria. Data were collected using focus group interviews. Four focus groups were used making a total of 17 participants. The principles applied for data analysis were those of Tesch’s method of data analysis, which were used to develop the themes and sub-themes. An independent coder assisted with the coding of the data for the purposes of trustworthiness. In addition, Lincoln and Guba’s model of trustworthiness consisting of the criteria of credibility, transferability, dependability and conformability was used to confirm the validity of the study while the ethical principles adopted were informed consent, justice, non-maleficence, privacy and confidentiality. The study found that the participants perceived numerous challenges that hindered the clinical preparedness of their students. These related to increased workload, lack of support from management and a lack of commitment on the part of students towards their studies. The participants also identified inconsistencies in clinical practice between the clinical midwives and the educators, and even among the educators themselves. This lack of consistency in turn causes confusion among the students and thus impacts negatively on their clinical practice preparedness. Based on these findings recommendations for clinical nursing practice, nursing education and research were made.

Description: South Africa is a country with 11 official languages including English. English, however, dominates the educational sector, as medium of instruction. This is despite a plethora of research that shows the cognitive advantages of mother tongue instruction and language policies that promote additive bilingual approaches. As subtractive language approaches characterise poor schooling contexts, the outcomes for students are poor. This is because they do not develop proficiency in any language. The abolition of apartheid in South Africa and the advent of democracy in 1994 resulted in dramatic changes in the education system. Nevertheless, the medium of instruction from Grade four has remained English. Consequently, for the majority of the population the education is in their second language. This study takes place in the higher education setting of a TVET college, namely the Dower Campus in Port Elizabeth. It focuses specifically on Level 2 (first year) Life Orientation students to consider the effect English has, as medium of instruction, on the academic performance of students. There is concern about the status of TVET colleges. Even though the higher education sector has transformed, these skills based colleges are still given inferior status in the eyes of the general public and students themselves. These students may be particularly at risk of success given that they have lower entry requirements than other students in the higher education sector. The subject Life Orientation was used to examine the effect of English on student performance. Life Orientation has come under scrutiny for its usefulness and it cognitive value. This study argues that it is a valuable subject for students at colleges, equipping them with knowledge to succeed at studies and in society at large. However, the pass rates for Life Orientation have been consistently low. The study wanted to probe the role of English in this performance. To address the aims and objectives of this study, relevant literature and various multilingual approaches were reviewed to determine which strategies might be most effective in helping students cope with English as medium of instruction. The study also presents a case for the development of indigenous languages as medium of instruction. The study used a mixed methods approach, that is both qualitative and quantitative methods, to explore the use, attitude and perceptions of English among lecturers and students. The research used an interpretive approach and the study took the form of a case study. The researcher took the stance of being a non-participant observer. Qualitative data was obtained through the use of interviews while quantitative data was obtained through the use of questionnaires. The interviews were recorded and transcribed by a transcriber. Data was analysed using a thematic approach. The results showed that majority of the students did not speak English frequently nor had it as a home language yet they all had a positive regard for the language. Many factors were responsible for student performance in Life Orientation such as attitude to subject, theoretical versus practical components of the subject and student background. However, the medium of instruction played a large role in this performance. Though lecturers foregrounded the importance of English as medium of instruction, they recognise that it was a barrier to understanding and affected student performance. Analysis of the lecturer interviews and the questionnaires with students revealed that students were experiencing difficulty speaking, reading and writing in English. Lecturers adapted their teaching strategies when teaching by including translanguaging strategies of code-switching to facilitate understanding. The data also indicated that code switching was considered by the lecturers to be the most suitable method in teaching to student. Code-meshing and written translations of material were not strategies employed by lecturers. Students indicated that they would prefer to write assignments drafts initially in mother tongue. The findings also suggested that it was necessary for the lecturer to use a variety of multilingual strategies to ensure that students enjoy success in Life Orientation. Based on the findings, this study makes recommendations regarding the teaching and learning of English to students which includes the use of multilingual classroom strategies, collaboration with language lecturers and development of a multilingual language policy to aid in the understanding and acquisition of English terminology used in LO content. Such a language policy should also seek to develop indigenous languages as mediums of instructions at the college.

Description: Background: Antenatal care is essential care that assists in maintaining a state of good health for the woman and her unborn baby. Globally the use of antenatal care services remains a challenge and this tendency is closely associated with maternal and neonatal mortalities and morbidities. South Africa has adopted a free service policy for pregnant women, their infants and for children up to the age of six. Despite this policy, the problem of limited utilisation of antenatal care services by pregnant women is still observed in this country and is associated with increased maternal and neonatal mortalities and morbidities.The purpose of the current proposed study was to explore and describe the reasons for limited utilisation of antenatal care services in the Mnquma sub-district, and to develop guidelines to assist the midwives to encourage the use of antenatal care services. Objectives:To explore and describe the reasons for the limited utilisation of antenatal care services by pregnant women at Mnquma sub-district.To explore and describe the knowledge of antenatal care services by the pregnant women.To develop guidelines to facilitate empowerment of midwives to enhance utilisation of antenatal care services by pregnant women in the Mnquma sub-district in Eastern Cape Province. The study was conducted in Mnquma sub-district during the months of July to January in 2016 using a qualitative, exploratory, descriptive and contextual research design. The research population were post-delivery women and the purposive sampling was used to identify women who met the stated criteria. One-on-one audio-taped semi-structured interviews were conducted and field notes were kept to justify some of the themes identified. Thirteen interviews were conducted and transcribed verbatim. Collected data was analysed using Tesch’s data analysis method. Trustworthiness was maintained through the standards of truth value, credibility, transferability, dependability and conformability. The ethical considerations of beneficence, justice, autonomy, non-maleficence and veracity were maintained. From the findings it emerged that the participants raised various concerns with regard to barriers influencing limited utilization of antenatal care services. The participants had limited knowledge of antenatal care services. Furthermore, participants recommended some solutions to enhance utilization of antenatal care services. Recommendations were made with regard to clinical practice, nursing education and nursing research. Guidelines were formulated to assist midwives to enhance the utilization of antenatal care services by pregnant women in the Mnquma sub-district in the Eastern Cape.

Description: This study was aimed at investigating the high level of consumer indebtedness in the South African retail market more specifically factors that contribute to consumer indebtedness. Recommendations on how to control the level of consumer indebtedness are also presented. Consumer indebtedness is a problem in many countries around the world and as witnessed during the 2008 global financial crisis, its impact can be disastrous. Not only does it create problems for the families but also for a country and even to the extent of the whole world. The literature conducted did not reveal a study undertaken to investigate factors that impact consumer indebtedness. Eight factors were identified and explored further in this study. Results were analysed in chapter three and outcomes presented in chapter four. The method used in conducting this study is the quantitative method. A questionnaire was developed based on the literature review conducted. The questionnaire was a five point Likert scale and was distributed to the respondents in the southern area of Tshwane Municipal district. In view of a manageable number of responses, results were analysed using an excel spreadsheet. Results were verified by an independent expert. From the eight factors that are identified, one (easy access to credit) was found to impact the high level of consumer indebtedness. Although there are other weaknesses, easy access to credit is found to be the main contributor. Recommendations on the findings are presented in chapter five of this study.

Description: Adsorption equilibrium and kinetics of methylene blue (MB) onto silica gel and aluminum pillared montmorillonite was studied in a batch system. Variables of the system include contact time, salt concentration and initial methylene blue concentration. Langmuir and Freundlich isotherm models were applied to experimental equilibrium data of methylene blue adsorption. Both models were suitable for the parameters. The advantage of silica gel as applied to water treatment is its high porosity when compared to aluminum pillared montmorillonite clay. Water molecules adhere to the silica gels surface because it exhibits a lower vapour pressure than the surrounding air. When equilibrium of equal pressure is reached, no more adsorption occurs. Thus the higher the humidity of the surrounding air, the greater the amount of water that is adsorbed before equilibrium is reached. The increase in pressure loss on the silica gel filters is 1.5 - 2.0 times smaller than in the case of sand filters, Lorenc (2007).

Description: This bilingual collection of short stories combines the fairy tale form and the Bizarro genre to explore the value system ingrained in me at a very early age via my conservative Afrikaans upbringing. To my mind the four characteristics of the fairy tale form as identified by Kate Bernheimer (in her path-breaking essay “Fairy Tale is form, Form is Fairy Tale”) namely flatness, abstraction, intuitive logic and normalized magic, also apply to the Bizarro genre. This intersection is exemplified by some of Bernheimer's own fiction, as well as the fiction of Aimee Bender and Lucy Corin, among others, all of whom have influenced my writing. , Hierdie tweetalige versameling kortverhale kombineer sprokieselemente met die van die Bizarro-genre, om die waardesisteem wat van kleins af deur my konserwatiewe Afrikaanse opvoeding by my ingeprent is, te ondersoek. Die vier eienskappe van die sprokie word deur Kate Bernheimer in haar baanbrekende opstel Fairy tale is form, Form is fairy tale uitgelê as: ’n onbetrokke verteller, abstraksie, instinktiewe logika en genormaliseerde towerkuns. Na my mening is dié vier eienskappe ook op die Bizarro-genre van toepassing. Hierdie oorvleuling is sigbaar in Bernheimer se fiksie en ook onder andere Lucy Corin en Aimee Bender s'n – skrywers wat my werk beïnvloed het. , This thesis is presented in two parts: Afrikaans and English.

Description: Data envelopment analysis (DEA) is used to assess the efficiency of 15 container terminals in Africa. The models proposed by Charnes, Cooper and Rhodes (1978) and Banker, Charnes and Cooper (1984) are used to determine and rank the efficiencies of the container terminals for 2013 and 2014. The results show that selected South African container terminals can improve on their operations relative to some of their neighbours to the North. Bootstrapping methods are used to investigate and clarify the results. The Malmquist Productivity Index (MPI) model is used to track and explain changes in efficiency over the period of assessment.
