Education is key to development strategies in Africa. We use overeducation and undereducation to analyse the effectiveness of education in preparing individuals for employment in Kenya and Ghana, using the Skills Towards Employment and Productivity Survey. Systematic differences in wages between matched, overeducated and undereducated workers hold…

This paper is designed to explore the current status of Chinese EFL teachers' use of digital resources in doing research and its influential factors. It classifies digital resources into six types aligned to the research process and uses the revised TAM to find out and explain its influential factors. A total of 180 teachers were investigated via…

The back-end databases of multi-tiered applications are a major data security concern for enterprises. The abundance of these systems and the emergence of new and different threats require multiple and overlapping security mechanisms.
