Macroeconomic determinants of environmental degradation in Africa: A STIRPAT model analysis

Environmental pressure in Africa is shaped by economic expansion, demographic scale and the energy required to sustain production, yet these relationships are difficult to identify when countries are exposed to common shocks and respond heterogeneously. This study revisits the ma...

Complex non-falciparum transmission and widespread insecticide resistance sustain hyperendemic malaria in Penka-Michel, a focus of the Cameroon highlands

A 12-month longitudinal entomological study (September 2023-August 2024) in the Western Highlands of Cameroon (Penka-Michel) investigated malaria transmission dynamics and insecticide resistance markers, including target-site resistance (L1014F, N1575Y, G119S- Ace1 ) and metaboli...

Paradigm shift in EFL Language Teaching: Looking for the Method for Effective Teaching

Change in teaching methods seems to be a constant in education. We can better understand and implement change in foreign language education if we look for connections between changes. The concept of paradigm shift offers one means of making such connections. This article describe...

Rethinking Intellectual Property for Sustainability in OAPI Member States: Exploring Linear and Nonlinear Relationships

ABSTRACT Research on the contribution of intellectual property to sustainability has begun to emerge in Africa; however, the relationship between these variables remains unclear. This article investigates both the linear and non‐linear effects of intellectual property on sustaina...

Unveiling the effects of state capacity on energy diversification in developing countries

Despite increasing scholarly attention on the determinants of energy diversification, the importance of state capacity remains under-examined, especially in developing countries. In this paper, we analyze how the fiscal and legal dimensions of state capacity affect energy diversi...

Nonlinear 2DOF van der Pol vibrations: El-Dib’s optimized frequency formula via the two-time-domains method

This paper presents a systematic decoupling framework for strongly coupled two-degree-of-freedom (2-DOF) nonlinear vibration systems. Here, the coupling is classified as strong rather than weak because the cross-mode interaction terms in the governing equations (e.g., the x 2 y-,...
