Static-Threshold-Limited on-Demand Guaranteed Service for Asynchronous Traffic in Timely-Token Protocol

In this paper, an improved Timely-Token protocol with enhanced best-effort service for improved capacity allocation to the asynchronous (that is, non real-time) traffic is proposed. Through analytical approach and the use of computer simulations, the improved Timely-Token protocol is compared with the existing Timely-Token protocol. In particular, if AT denotes a threshold value, then, when compared to the existing Timely-Token protocol, the improved protocol will allocate additional average of AT time units to the asynchronous traffic in every cycle

Use of mixed methods designs in substance research: a methodological necessity in Nigeria

The utility of mixed methods (qualitative and quantitative) is becoming increasingly accepted in health sciences, but substance studies are yet to substantially benefit from such utilities. While there is a growing number of mixed methods alcohol articles concerning developed countries, developing nations are yet to embrace this method. In the Nigerian context, the importance of mixed methods research is yet to be acknowledged. This article therefore, draws on alcohol studies to argue that mixed methods designs will better equip scholars to understand, explore, describe and explain why alcohol consumption and its related problems are increasing in Nigeria. It argues that as motives for consuming alcohol in contemporary Nigeria are multiple, complex and evolving, mixed method approaches that provide multiple pathways for proffering solutions to problems should be embraced
