The Upper Guinea Coast in Global Perspective

For centuries, Africa’s Upper Guinea Coast region has been the site of regional and global interactions, with societies from different parts of the African continent and beyond engaging in economic trade, cultural exchange, and various forms of conflict. This book provides a wide-ranging look at how such encounters have continued into the present day, identifying the disruptions and continuities in religion, language, economics, and various other social phenomena that have resulted. These accounts show a region that, while still grappling with the legacies of colonialism and the slave trade, is both shaped by and an important actor within ever-denser global networks, exhibiting consistent transformation and creative adaptation

Online Auctions with Dual-Threshold Algorithms: An Experimental Study and Practical Evaluation

Online auctions are a viable alternative to conventional posted price mechanisms. Agrawal, Wang, and Ye [1] have proposed two primal-dual algorithms for revenue-maximizing multi-item allocation tasks. Although promising in terms of theoretical properties and competitive ratios, there is alack of evidence regarding the real-world practicability of these mechanisms, for instance referring to online auction-based tickets sales. In this paper, we conduct an experimental study on both the One-Time Learning Algorithm(OLA) and the Dynamic Learning Algorithm (DLA) based on synthetic data, revealing the remarkable aptitude of the latter for non-trivial online auctions. Being robust to most input variations, the inherent dynamic update of dual thresholds achieves a superior balance with respect to the trade-off between objective function values and runtimes. We address critical sensitivities quantitatively and draft several small extensions by incorporating input distribution knowledge
