    A Systematic Review Protocol for the Effectiveness of Psycho-Educational Intervention Programmes in Addressing the Psychological Risk Factors Associated with Non-Communicable Diseases among Adolescents
    (MDPI, 2023-07-28) Bokolo, Nokwanda P.; Van Niekerk, Rudolph Leon; Mathews, Verona; Leach, Lloyd; Apter, A.
    The psychological health concerns and risk factors associated with non-communicable disease among adolescents have been prioritized on the agenda of international health institutions globally. The aims of this systematic review are to determine the various types of psycho-educational intervention programmes developed to address the psychological risk factors associated with noncommunicable diseases among adolescents, and to assess the effectiveness of the psycho-educational intervention programmes. The systematic review will include case–control and randomized controlled studies. The review will be conducted using the following electronic databases, PubMed, CINAHL, Science Direct, Cochrane Library, SCOPUS, and ERIC, as well as the grey literature for the thesis repository from 2012 to 2022. The key search terms will include intervention programme, adolescents (aged 10–19 years), psychological risk factors and non-communicable diseases. The studies identified by the search strategy will be downloaded into Mendeley and exported to Covidence software for screening, quality assessment and data extraction. The quality assessment tool that will be utilized is the Joanna Briggs Institute critical appraisal checklists to ensure relevance and quality of the articles. This systematic review will use two types of data analysis: narrative synthesis of qualitative studies and meta-analysis of quantitative studies. The findings from this systematic review will provide evidence-based tools for the management of psychological risk factors associated with non-communicable diseases, as well as present key insights for future intervention programs on the management of psychological risk factors associated with NCDs among adolescents.

    Electric vehicle battery remanufacturing: circular economy leadership and workforce development
    (MDPI, 2024-09-18) Chigbu, Bianca Ifeoma; Nekwevha, Fhulu H.; Umejesi, Ikechukwu
    Given the increasing momentum globally towards sustainable transportation, the remanufacturing of used electric vehicle lithium-ion batteries (EV LIBs) emerges as a critical opportunity to promote the principles of the circular economy. Existing research highlights the significance of remanufacturing in resource conservation and waste reduction. Nevertheless, detailed insights into South Africa’s (SA’s) specific capabilities and strategic approaches in the context of used EV LIBs remain sparse. By utilizing in-depth interviews with fifteen key industry stakeholders and drawing on institutional theory, this qualitative study evaluates SA’s infrastructure, technical expertise, and regulatory frameworks in the EV LIB remanufacturing sector to address this gap. The findings reveal proactive strategies, including technical expertise, sustainable infrastructure, and robust regulatory frameworks aligned with global standards. This study proposes strategic initiatives like the Interdisciplinary Innovation Hub and Mobile Remanufacturing Labs, which are analytically derived from stakeholder insights and aim to predict potential pathways for workforce development, especially in rural areas. Innovative training programs, including the Virtual Reality Consortium, Circular Economy Institutes, and the Real-world Challenges Program, will ensure a skilled workforce committed to sustainability and circular economy principles. The conclusions highlight SA’s potential to become a leader in EV LIB remanufacturing by integrating circular economy principles, enhancing technical expertise, and fostering international collaboration.

    Street Food vending on Poverty and Unemployment in the Mahikeng Local Municipality, South Africa
    (Adonis & Abbey Publishers, 2022-12) Ekobi, GA.
    The South African street food industry is essential in elevating the socioeconomic standing of sellers. However, most studies on street food vending focused on perception, safety, consumption, and handling of street food. Therefore, it is necessary to fill this gap. The study explores street food vending contribution on poverty and unemployment in the Mahikeng Local Municipality. The study's goal was accomplished by using a mixed research methodology. A sample size of 401 respondents were selected for the study and data was obtained using structured, semi-structured and unstructured questionnaires. The study found that street food vending creates jobs not only for the people involved in the trade, but also for people who would otherwise be unemployed, for example, those who are retrenched. In addition, street food distribution has become a cornerstone for vendors to generate income to supplement family income that improved the standard of living of the vendors. Additionally, some vendors were able to acquire assets such as livestock and landed property from the profit made from the business, contributing to reducing poverty incidence among traders in the area. The paper concludes that street food vending has contributed in creating jobs thus, reducing poverty incidence. However, the street food industry continues to confront obstacles such as lack of cash and credit and location-based business restrictions. Therefore, in order for SFV to be effective, steps must be taken to minimise the difficulties affecting the industry
