Does The National Benchmark Quantitative Literacy Test Predict Performance In Stem Programmes In Commerce, Engineering And Science?, Robert N. Prince

Numeracy

In South Africa, university completion rates remain low, with only 23% of students finishing within the regulation time (three or four years). These completion rates continue to reflect racial inequalities, with ‘White’ students significantly more likely to complete degrees in professional fields such as engineering and commerce compared to their ‘African’ counterparts. To address these challenges, the South African higher education institutions, through their umbrella body, introduced the National Benchmark (NB) tests to assess students’ academic literacy skills—including quantitative literacy, academic literacy, and mathematics—to identify those most at risk of struggling with the curriculum. The NB tests aim to evaluate …

Aging And The Screen: Toxic Commodification Of The Female Body In The Substance (2024), Damlasu Uyug Sengun, Tuncer Mert Aydın, Zeynep Ozdamar Ertekin

Markets, Globalization & Development Review

Representations of the aging female body have increased in media, but their presence is still shaped by social norms and market-driven ideals. On the contrary, The Substance (2024), an absurd, postmodern body horror, provides us a provocative critique of contemporary society’s obsession with youth and beauty and the way our culture defines and commodifies aging, especially in relation to women’s bodies and identities. Our review of The Substance incorporates consumer culture theory with Julia Kristeva’s concept of the abject (1982), Laura Mulvey’s theory of the male gaze (1975), and Barbara Creed’s notion of the monstrous-feminine, (1993) to explore the toxic …


Navigating The Open-Loops: Actor Dynamics And Bottlenecks In The Transition Towards Circular Household Waste Supply Chains, Burcin Ozdamar, Aysu Göçer Nov 2025

Navigating The Open-Loops: Actor Dynamics And Bottlenecks In The Transition Towards Circular Household Waste Supply Chains, Burcin Ozdamar, Aysu Göçer

Markets, Globalization & Development Review

Household waste supply chains (HWSCs) in developing countries often suffer from fragmented actor structures, weak coordination, and informal practices that limit their overall performance and circularity potential. Existing studies tend to focus on isolated aspects such as waste types, technologies, or individual actors, without systematically examining the broader network and interdependencies shaping HWSC outcomes. Addressing this gap, this study investigates the key components (e.g. actors and waste processes) and bottleneck points that hinder the structure and functioning of current HWSCs to transform into circular systems. Drawing on industrial network theory, the research analyzes how actor relationships and system configurations influence …
