A two-year, (2015 and 2016) field trial was conducted in Obudu Local Government Area of Cross River State to compare the efficacies six (6) selected herbicides controlling spear grass (Imperata cylindrical Linn) cassava farm. The main treatments were three varieties: TMS 30572, 50395 NR 8082, while sub herbicides: Primextra, Igrancombi Gold, Paracot as pre-emergence, Touchdown Forte Hi Tech, Ga...

This paper explores the relationship between what influences and shapes the unique and locally situated method-in-action and how it consequently emerges. Based on a synthesis of prominent Information Systems (Development) literature, an analytical framework is developed. The framework is organised into three perspectives: 1) the structuralist, 2) the individualist and 3) the interactive process...

Lately, distributed applications have been improved with the emergence of a great number of different terminals and networks. Adaptability has become a common approach to solve heterogeneity problems involved by the use of multiple devices. Indeed, we have introduced global adaptation to improve merging adaptability with distributed applications. Global adaptation allows dynamic, transparent an...

Agencies consisting of simple agents can be deployed on the Internet to solve problems that are too complex for single autonomous Internet agents. We deploy Bayesian agencies on the Internet to achieve emergent belief propagation through the collective behavior of simple agents organized into heterarchies of agencies. Collectively the agents use probabilistic reasoning to deal with the uncertai...

Information and communications technologies (ICTs) have been at the heart of a transformation of public services in the UK, in a process that has seen the emergence of forms of 'electronic public services' (EPS). Policy makers have hoped that EPS will bring about improved, convenient, accessible and cheaper public services. The Internet has been at the heart of attempts to deliver EPS. However,...

In this paper we describe the design, implementation and evaluation of a software framework that supports the development of mobile, context-aware trails-based applications. A trail is a contextually scheduled collection of activities and represents a generic model that can be used to satisfy the activity management requirements of a wide range of context-based time management applications. Tra...

In this paper we identify roles and uses of web-based tutorials through an examination of tutorials’ comments sections. Through this analytical lens, we find that web tutorials serve a variety of needs, providing: in-task help for users with an immediate, specific goal to accomplish; a means for users to proactively expand their repertoire of skills; and an opportunity for novices to shadow and...
