Cocoa (Theobroma cacao) and local fruit species interaction: Case of Beilschmiedia mannii in traditional agroforestry systems in western Côte d'Ivoire

Cocoa (Theobroma cacao) cultivation in Côte d'Ivoire faces many constraints and remains one of the main causes of deforestation. However, cocoa-based agroforestry and the domestication of cocoa companion trees would be an alternative to overcome these constraints. This study was conducted to improve the sustainability of cocoa production through its association with "Bitéi" (Beilschmiedia...

Capital, risk and efficiency tradeoffs in Cameroonian banking

This paper analyzes the relationship between capital, risk and efficiency for a sample of 10 Cameroonian banks between 2014 and 2020. To reach the authors’ target, they specify a system of equations and estimate it using the two stage least squares panel data estimator technique. The empirical analysis shows that increases of bank capital do not reduce risk taking in Cameroonian commercial banks. Moreover, cost...

An analysis of student decision making for educational recommender systems

Recommender systems in education aim to help students make good decisions about the direction of their learning. The design of such systems in conventional research has treated the decision making process of students as a black box and assumes the best recommendations to be those that accurately predict student choices. Such an approach overlooks potentially valuable use cases for supporting optimal decision making,...
