The COVID-19 pandemic with its concomitant lockdown policies exacerbated the worst living conditions in different regions of the world, Africa and Ghana in particular. The major discursive issues concerning the pandemic has glaringly or cunningly ignored the lack of emphasis on local dynamics concerning what ought to be or could have been done…[Read more]

This study seeks to understand the role played by social factors in the diffusion of parasitology to Puerto Rico, in particular those affecting the work of Bailey K. Ashford between 1898-1934. Most studies of Ashford to date focus mainly on the intellectual framework per se, and rarely on the surrounding social environment. In order to achieve…[Read more]

In the 1930s, the Academy of Motion Picture Arts and Sciences implemented a technical standard—known as Academy Mono, or the Academy Curve—that dramatically impaired the sound quality of motion pictures. This article accounts for why the major studios agreed to this restrictive standard. I argue that they adopted Academy Mono to curtail the pow…[Read more]

(A) The first part of this paper demonstrates the feasibility of a DAF-filtration water treatment system for removal of humic substances and 400 color units from a contaminated water. Trihalomethanes are primarily formed by the reaction of free chlorine with humic substances, such as humic acid and fulvic acid, called trihalomethane precursors. A…[Read more]

The climate impacts of the information and communications technology sector—and Big Data especially—is a topic of growing public and industry concern, though attempts to quantify its carbon footprint have produced contradictory results. Some studies argue that information and communications technology’s global carbon footprint is set to rise dra…[Read more]
