The entrepreneurial ecosystems (EE) approach is often promoted for Africa’s growth, but Africa already has many entrepreneurs. Instead of increasing entrepreneurship, researchers argue for strategies drawn from East Asia’s development and Schumpeterian growth theory—both of which oppose EE thinking. These approaches suggest that Africa should focus on building large, productive firms and absorbing existing technologies, rather than relying on start-ups, to achieve long-term, sustainable economic development.

New research reveals a surprising geometric link between human and machine learning. A mathematical property called convexity may help explain how brains and algorithms form concepts and make sense of the world.

A groundbreaking study reveals how strain rate influences anthracite crack characteristic Sstress under dynamic loading, offering a predictive model to assess crack stress thresholds. This research provides critical insights into damage evolution mechanisms, advancing strategies to predict and mitigate catastrophic events like rock bursts in underground mining.

How do piezoelectric actuators perform under extreme conditions such as high temperatures, strong vibrations, and nanoscale precision tasks?

In a review published in the International Journal of Extreme Manufacturing, researchers examine their use in five major areas including positioning and alignment, biomedical devices, microrobotics, vibration mitigation, and advanced manufacturing.

The study highlights recent progress in materials, control methods, and system design that could support the development of more reliable and efficient precision technologies.
