Dancing with decolonial curriculum theorists : technology as a shapeshifter in art and design education
(UJ Press, 2024-9-15) Olalere, Folasayo Enoch; Makwela, Mashaole Jacob; Fomunyam, Kehdinga George
In the past two decades, the concept of decolonisation of higher education in South Africa gained momentum. Amidst this growing concern, the role players in the education sector have interrogated their role in this discourse and examined how curricula and pedagogical approaches can stand up to this call for decolonisation. Some decolonial theorists have associated the concept with changing the nature of knowledge, shifting our position in relation to knowledge, and economic transformation. Even though there are multiple views and schools of thought, the question that remains unanswered in curriculum development is what the concept of decolonisation will look like in technologically advanced university settings.
Investigating top-down cracking of pavement in recycled waste plastic asphalt
(Materials Research Forum LLC, 2025-3-25) Abejide, Samuel; Adedeji, Jacob; Mostafa, Mohamed Mostafa Hassan
Abstract. This study investigates a new approach for the use of an alternative sustainable wearing course material on flexible pavement roads (recycled asphalt plastic pavement). Highway infrastructure plays a major key role in the domestic transportation of people, goods and services within the community and from a national perspective. Thus, highway infrastructure provides provincial and local accessibility, which promotes the growth and development of the economy. For this reason, there is a need to develop a sustainable approach to increase the efficiency of transportation infrastructure. The purpose of this study was to evaluate top-down fatigue cracking failure mode of asphaltic wearing courses for use in in pavement overlays, at high traffic intersection points and on parking sections using dual tire loads in finite element analysis. The process of developing alternative mixing materials is initiated by the need to provide a stable mixture for use on field sections different from cold mix or conventional hot mix (HMA) materials, which is subjected to stripping delamination mode with increasing moisture content. In this study, it was observed that the bonds formed between the molten plastic material has the potential to bind the bitumen and the aggregates together as a homogenous material in such a way that, when hardened at reduced temperatures, the mix is able to form a stronger bonded material that is semipervious and allows drainage of moisture or water across the surface of the asphalt plastic layer. This study adopts an alternative approach to the design of an ultrathin film asphalt concrete porous pavement layer for use in pavement surface wearing course and high-density traffic roads considering the effects of increasing temperature and moisture absorption on the asphalt plastic pavement mix.
Investigating the effect of investor sentiment on stock return sensitivity to fundamental factors : case of JSE listed companies
(Informa UK Limited, 2024-12-31) Fonou-Dombeu, Nyanine Chuele; Nomlala, Bomi Cyril; Nyide, Celani John
This study examines the association between a firm’s fundamental factors and stock returns as well as how investor sentiment influences the association between these variables. The fundamental factors analyzed include accounting variables (earnings yields, change in profitability, and capital investment) and earnings quality measures. Investor sentiment is measured using the South African consumer confidence index. A sample of 1 386 firm-year observations from the companies listed on the Johannesburg Stock Exchange (JSE) between 1990 and 2022 was used. The results show that fundamental factors are related to stock returns, except for measures of earnings quality. Although earnings yields and capital investments cause variation in stock returns, their effects on stock returns are influenced by other variables associated with stock returns. In addition, investor sentiment affects the relationship between fundamental factors and stock returns, suggesting that sentiment influences the outcome of the capital market and the way investors process fundamental information. Profitability seems to be more related to stock returns than other fundamental variables. This study sheds light on how sentiment interacts with a set of fundamental factors and their sensitivity to stock returns and highlights the important role of investor sentiment and accounting information in the capital market.
Curriculum potential for theory, theorising, and praxis

Balancing acts : navigating research challenges as a female academic in higher education
(IGI Global, 2025-5-16) Thamae, Mamothibe Amelia; Mdikana, Andile Alfred
The author generated no research outputs in the past two decades, resulting in limited career trajectories in academia that require research publications in accredited, reputable journals and books. To go up the ranks in Higher Education Institutions, the author is expected to actively contribute to knowledge production as evidenced by scholarly articles, graduate doctoral students in record time, secure research grants and visiting scholars. As a result of the lack of research outputs, the author appears stuck since the author cannot apply for any promotion that requires recent publications. This study contributes to current debates on research outputs, university rankings, sustainability of Higher Education Institutions, staff promotion policies, and neoliberal principles' impact on Higher Education. This conceptual study employs an interpretivist paradigm that uses data from the diaries and notes on the author's experiences across Institutions. In this light, this chapter explores the challenges that females encounter in HEIs and contribute to few or no research outputs.
