    No full text
    Text in English with summaries in English, Xhosa and TswanaThe study explored how single women experienced singlism, through an Afrocentric and feminist-phenomenology intersectionality. It further examined how single women in senior management experienced the South Africa public sector work environment with all their other roles. The literature review revealed the extent of existing related research; the definition of key terms emerged, and the findings of the study were integrated with existing information. Further, single women’s formative years were contextualised through socialisation within a patriarchal African culture, with strong views on masculinity and femininity. The research investigated dominant and influential role models and circumstances that shaped single women’s worldview. It explored experiences of singlism in society and at work. The conclusions identified links to childhood experiences and adult choices. Data collection was done through in-depth interviews with participants. Themes and sub-themes were developed from the data collected through the in-depth interviews. The main contribution of this study is on expansion of singlism as also an embodiment of positive attributes based on single women perspectives. METHOD: The Afrocentrism and feminist phenomenology paradigms were adopted for this study. In-depth interviews were used for data collection. The data analysis was achieved through identifying themes and deriving trends from shared experiences. FINDINGS: Singleness is a conscious choice; independent, ambitious women value their freedom; the public service is experienced as hostile to single women; enablers for single women include family, domestic helpers, and boarding schools; single women are determined to shape a better future for women in the public service. Recommendations were made about improvements and relevant future research on the same or similar topics.Uphandonzulu luphonononge indlela amabhinqa angatshatanga azakha ngayo izazisi zabo kunye nendlela abafumane ngayo amava okungatshati ngokuhlanganisa indlela yaseAfrika kunye nobubhinqa befinomeloji.

    Text in English, abstract in English, Zulu and AfrikaansThis study sought to investigate how Grade 11 Life Sciences teachers integrate ICTs in their teaching and learning. The lens that was used to frame this study was Technological Pedagogical and Content Knowledge (TPACK) theory; the research paradigm was interpretivist; and the qualitative design case study was followed. Three high schools in Beaufort West in the Western Cape were the natural settings where the study was conducted. The data collection strategies that were used were non-participant observation, semi-structured interviews, and document analysis. Three teachers who participated in the study were purposely sampled as they taught Grade 11 Life Sciences using ICT. During this study, trustworthiness was maintained by applying credibility. Ethical clearance was also taken into consideration by using voluntary participation, anonymity, informed consent, and confidentiality. The research question addressed in this study was: How do Grade 11 Life Sciences teachers integrate ICT in their teaching and learning? The results indicate that teachers integrate ICT into their teaching and learning through various ICT tools such as videos, laptops, data projectors, using interactive and normal whiteboards, and displaying pictures. Teaching experience can assist in the choice of ICT for the presentation of a lesson and in engaging with learners during lessons. The use of ICT in teaching Life Sciences makes teachers comfortable as the deliver their lessons. The results also indicated that having ICT policies at school is important as this information can assist in the use of ICT in schools. The recommendations of this study are that teachers must be trained on how to use ICT optimally in teaching and learning.Lolu cwaningo luphenye izindlela othisha beBanga le-11 beSayensi yezeMpilo abadidiyela ngazo ubuchwepheshe boLwazi noBuchwepheshe bokuXhumana (ICT) ekufundiseni nasekufundeni kwabo.

    Institutional repositories are increasingly being adopted by universities in Ghana to preserve and communicate research findings and intellectual outputs to audiences within and outside the institution. Nonetheless, there is a growing concern about the sustainability of these repositories. In view of this, the study investigated the managerial and technical issues that confront the sustainability of institutional repositories (IRs) of selected public universities in Ghana. The dynamics of innovation model and the diffusion of innovation theory served as the lens that guided the study. Eight hundred and thirty (830) respondents comprising of IR managers, Library Staff (Digitalization and E-resources Units), Post Graduate Students, Lecturers, and University Librarians from five public universities in Ghana were sampled for the study using multiple sampling techniques. The study yielded an overall response rate of 92.8%. Data was collected using self-administered questionnaires, a semi-structured interview guide, and the analysis of IR policies and websites. The internal consistency reliability of the research instruments was tested using the Cronbach alpha (α=0.81). The quantitative data that was collected through a questionnaire was analysed descriptively using the SPSS software. The qualitative data was analysed using NVivo software. The transcribed interview responses were imported into NVivo software and categorised into nodes or themes based on the research questions. Both the qualitative data and quantitative data were integrated at the discussion stage of the study. The findings of the study revealed that the concept of IRs is not new in Ghana. However, inadequate funding, ICT Infrastructure, bandwidth, publisher copyright restrictions and the lack of technical staff for system development and management of IRs were identified as major challenges that confront IR participation and threatens its long-term survival and sustainability in Ghana. Also, IR policies guided content submission, usage, operation and management of repositories in public universities in Ghana. However, content submission to IRs by faculty members was found to be low. This was largely attributed to the persuasive nature of the IR policies. The study recommends the need for a policy implementation strategy and underscores the importance of policy in addressing the numerous challenges that threatens the sustainability of the IRs. Consequently, it proposes a framework that may contribute to ensuring the sustainability of the IRs in public universities in Ghana.D. Litt. et. Phil. (Information Science)Information Scienc

    The percentage of female offenders who are single mothers of minor children is a growing concern among the total female incarceration population in South Africa and globally. This study aimed to explore how expectations about mothering bear out for incarcerated mothers who are physically separated from their children. The experience of motherhood was captured using face-to-face interviews with a guide of semi-structured questions with eight (8) incarcerated mothers at Johannesburg correctional facility, Gauteng province, South Africa. The data were analysed using Interpretative Phenomenological Analysis (IPA) couched with Social Identity Theory (SIT) and revealed that circumstances that led to maternal pathways differed from the literature. The findings of this study provided a foundation of how the social context, together with maternal obligation, influences behaviours that women internalise, and which lead to offending behaviours. This warrants further research in an effort to curb and prevent maternal incarceration.Diphesente tsa bagolegwa ba basadi ba go hloka balekani ba e lego bommagobana ba bannyane ke tlhobaboroko go palomoka ya basadi bao ba golegilwego ka Afrika Borwa le lefaseng ka bophara.

    Managing road traffic congestion on Allandale road (M39) in Midrand, South Africa

    No full text
    Traffic congestion is a challenge in cities around the world, and is generated by the significant growth in vehicle ownership and rapid urbanisation. In South Africa, it has become problematic for road transport users, and challenging for policymakers. The rapid increase in the total number of vehicles per capita has resulted in the metropolitan public traffic systems, specifically, being unable to fulfil the travel demand of occupants. In Gauteng, for example, this problem causes travel delays and contributes to low economic productivity. Traffic congestion results in the irregular flow of traffic on Allandale Road, which negatively contributes to the imbalanced process of economic activities in the Midrand area. The current study aimed to investigate the management of road traffic congestion on Allandale Road (M39) in Midrand. The study employed an exploratory sequential mixed-method research approach. The first phase was a qualitative study that consisted of interviews with 18 participants. The second phase, the quantitative study, utilised an online structured questionnaire that was completed by 276 respondents. The study revealed that traffic congestion does occur on Allandale Road in Midrand, and that it is not adequately managed. The outcomes showed a period of peak traffic congestion from 6:00 to 9:00 (mornings), and 15:30 to 18:00 (afternoons) during the week. The factors contributing to road traffic congestion are increased vehicle ownership, population growth, new developments, roadworks or construction projects, and mismanagement of the road traffic system. The study found that the key applicable pieces of legislation are the National Road Traffic Act 93 of 1996, White Paper on National Transport Policy of 1996, Road Traffic Management Corporation Act 20 of 1999, National Land Transport Act of 2009 and the Draft National Non-Motorised Transport Policy. The results indicated that there are strategies that will better manage traffic congestion, including physical and improvement strategies. The strategies include public transport and infrastructure improvement, the introduction of carpooling, the promotion of non-motorised transport services, park-and-ride facilities, and the involvement of developers’ impact assessments. The physical improvement strategies include additional new roads, street connectivity, public information systems, bottleneck relief, and dedicated lanes for buses/Bus Rapid Transport systems. The operational improvement strategies are incident management, planned special event traffic management, traffic signal timing and coordination, and active road management by the Metro Police. The study concludes with a framework that could be used to manage road traffic congestion.M. Com. (Transport Economics)Economic

    A Conceptual Framework for the Development of Argumentation Skills Using CSCL in a Graduate Students’ Research Course

    No full text
    Developing and presenting a well-formulated research argument is core to the learning journey of a graduate student. In open distance e-learning, computer-supported learning is instrumental in providing a platform for graduate students to develop their argumentation skills. However, there is little guidance on the elements required in using computer supportive collaborative learning (CSCL) to augment argumentation skills development (ASD). This paper reports on elements identified in literature that should be present in a framework using CSCL to augment ASD. The thematically analysed data gathered during the focus group sessions were used to confirm the structure of the argumentation skills development framework (ASDF), and confirmed that there is a need for a framework to provide guidance in using CSCL to augment ASD. The contribution includes the conceptual ASDF using CSCL, comprising seven elements, that provides a strategy of scaffolded learning for implementation in a graduate course to augment ASD

    Application and optimization of artificial intelligence techniques for small to medium sized manufacturing enterprises in an industry 4.0 environment

    No full text
    The ascent of the current industrial revolution known as Industry 4.0 (I40) or smart manufacturing is considerably impacting the manufacturing sector with the utilization of more intelligent and advanced practices such as Artificial Intelligence (AI) methods and Machine Learning (ML) within factories. The successful implementation of intelligent practices promises to significantly increase organization flexibility, improve operations, and increase production throughput. Without a doubt, to remain relevant in the competitive market and ensure their future growth, manufacturing companies should start actively considering and adopting advanced and intelligent I40 solutions for their businesses. Manufacturing small and medium-scaled enterprises (SMEs) represent the backbone of several countries’ economies, actively supporting jobs creations and contributing to Gross Domestic Product (GDP). However, SMEs have been the least appealing in embracing new and advanced technological trends within their production processes, mainly due to a lack of appropriate practical guidance or solutions customized to their environment and limited resources (financial and human) in their organizations. Few of the existing works intending to encourage manufacturing SMEs in adopting new technological trends are high-level frameworks, surveys, or only tackle the design of advanced technological solutions without incorporating the corresponding organizational amendments SMEs need to undergo for a sustainable implementation of advanced and innovative solutions. Inspired by some of the technical and organizational challenges of manufacturing SMEs, we utilize the Design Science Research Methodology (DSRM) to create, illustrate, and assess several AI and innovative techniques that increase manufacturing SMEs’ performance. The AI concepts and advanced technological methods we design in this study improve several existing solutions developed by our predecessors in the research field. Our major research contributions are the creation of a practical guide for the application of various AI techniques and innovative solutions adapted and optimized for manufacturing SMEs such as intelligent predictive maintenance (PM) method, automatic parameter configuration for Supervisory Control And Data Acquisition (SCADA) system, product customization framework, robust communication network prototype, and enhanced safety response mechanism. We implement various advanced technologies like ML, Time-Sensitive Networking (TSN), speech recognition, and more to empower our innovative solutions. Our study is valuable to the SME research field (in academia). It provides new literature that combines the design of advanced and optimized technological trends with organization structural (business model) changes to promote innovation within SMEs, prompting more research in that regard. Since we are motivated by some of the manufacturing SMEs' challenges, our research is also useful to the industry as it provides practical solutions that manufacturing SMEs can adapt and implement to boost their production processes performances.Ph.

    Inpatient substance user's care and treatment: innovative guiding principles for nurses

    No full text
    Substances use is an increasing national concern. Various forms of harmful disorders have also been noted as posing a national health crisis. Against this background, the aim of the study was to explore, identify, describe and analyse inpatient substance addiction and its disorders, and to propose a relevant framework of principles to guide and improve nursing care in this regard. The study adopted a combined mixed-methods research approach involving qualitative, quantitative, using convergent research design in order to maximise both the efficacy of the methods and sources of data collection and their concurrent analysis, as well as the eventual findings of the study, which was conducted at three substance addiction treatment centres in Gauteng Province. The quantitative aspect of the study was facilitated by means of a comprehensive review and analysis of admission records belonging to 244 substance addicted inpatients at one of the selected three treatment centres. The quantitative variables reflected in the admission records represented the entire range of sociodemographic, help seeking, substance abuse history, family support, and medical and psychological characteristics of substance abusers. On the other hand, the study’s qualitative aspect was facilitated by means of three (3) unstructured in-depth focus groups with selected nurses providing care to inpatient people addicted to substances. An investigation of 5 (five) inpatient treatment programmes at the self-same three treatment centres complemented the qualitative aspect of the study. For the majority cases of occurrence/ frequency at the treatment centre from which 244 admission records were obtained, the quantitative findings revealed, among others, that the majority of inpatients (n=224, 91.8%) were Blacks; single (n=223, 90%); at secondary school (n=207, 84.8%); unemployed (n=232, 95.1%); with the heroin as the most abused substance by 88.9% (n=217) inpatients followed by cannabis (n=205, 83.6%). The most critical of these variables was that the majority of the inpatients (n=74, 30.5%) were those who had been substance abusing for 7-10 years. The implication is most young people were the most at-risk group as they started substance abuse during the adolescent stages of their live, which increased the chances of progressing to substance abuse disorders and poor mental health. Meanwhile, the qualitative findings derived from the focus group discussions with the nurses and the five treatment programmes yielded five focal themes and associated multiple sub-categories. These principal/global themes are: psychological and emotional impediments to inpatient care; attitudes of patients’ relatives; quality of care by nurses to support inpatients; nurses’ attitudes; and challenges experienced by nurses. Collectively, both the quantitative and qualitative findings indicate that substance abuse disorder is a complex and multifaceted physiological and psychosocial challenge for both the sufferers and society as a whole. For its management and treatment, nurses should be adequately trained, and multi-professional teams should be part of a concerted and dedicated effort to provide care and eradicate the problem convincingly. The study envisages that its recommendations will contribute towards effective policy development and implementation based on a viable framework of inmate substance abuse guidelines to innovatively guide nursing care and management of substance abuse treatment centres. Such innovation should incorporate continuing professional development guidelines for different categories of nurses to enhance their skills and also improve knowledge on mental health implications as well.Ph.

    Evaluation and optimization of a stand-alone solar driven membrane filtration system for surface water treatment

    No full text
    South Africa is classified as a water-stressed country and is faced with widespread water scarcity. Water scarcity is worse in rural areas of the country where a third of the population still reside. This is due to low levels of development with no water treatment systems or piping networks and most of rural areas lack access to electricity thereby hindering the installation of conventional water treatment facilities. Membrane technology presents an opportunity to bring water treatment facilities to these areas due to its compact nature, consistent water quality production and ease of maintenance. Among membrane systems, ultrafiltration uses comparably low pressures hence making it energy efficient. Solar energy has been proven to be effective in providing energy to drive membrane filtration systems and its utility in South Africa is very viable due to the abundance of solar insolence. South Africa receives an average of 2500 hours of sunshine per year and with solar radiation reaching up to 6,5kWh/m2 on some days, thereby making the use of solar energy highly favourable. In this research, water production by a solar hydraulic pump was optimized. A nanofluid was developed to improve the thermal conductivity of the working fluid for the pump and a custom-made ultrafiltration membrane was adopted for use in the membrane filtration unit. Heat transfer mechanisms within the system were investigated and the membrane filtration performances on real surface water samples collected from a lake and a stream were also determined. The nanoparticles and membranes were characterized using Scanning Electron Microscopy (SEM), Atomic Force Microscopy (AFM), Fourier Transform Infrared (FTIR) spectroscopy, Zeta-potential, drop-shape analysis, dynamic light scattering, and stability tests. Laboratory-scale application of the system was then done together with real-world studies. The optimum conditions were established to be a nanofluid composition of 0,1 %w/w CuO working fluid operated within the temperature range of 25oC – 50oC and at a pH of 6. This significantly improved the net water production of the developed prototype by 13,35 % as well as the efficiency of the prototype by 21,3%.M. Sc. (Chemistry)Chemistr
