Most existing ICT for development (ICT4D) literature tends to focus mainly on design, transfer and implementation issues. There is limited focus on the impact of ICT projects on development and little concrete analysis of these initiatives in terms of their long-term developmental impact. In this paper, we draw upon Luke's (1974) concept of power and Sen's (1999) notion of capabilities as an evaluative space for ICT project assessment. The novel approach taken from Luke's concept of power with Sen's capability approach attempts to understand the social powers that may inhibit or enable individuals from taking full advantage of ICT resources for furtherance of their lives. The framework's utility is illustrated with a case study based on an empirical work in the Nigerian electricity sector. The combined framework and case study contribute to knowledge on the development of theory and informs practice by offering a novel approach to examining ICT-led developmental projects. The study concludes with some implications for policy makers advancing an agenda on "ICT for Development".

The work reported in this paper is motivated towards validating an alternative approach for fault tolerance over traditional methods like checkpointing that constrain efficacious fault tolerance. Can agent intelligence be used to achieve fault tolerant parallel computing systems? If so, "What agent capabilities are required for fault tolerance?", "What parallel computational tasks can benefit from such agent capabilities?" and "How can agent capabilities be implemented for fault tolerance?" need to be addressed. Cognitive capabilities essential for achieving fault tolerance through agents are considered. Parallel reduction algorithms are identified as a class of algorithms that can benefit from cognitive agent capabilities. The Message Passing Interface is utilized for implementing an intelligent agent based approach. Preliminary results obtained from the experiments validate the feasibility of an agent based approach for achieving fault tolerance in parallel computing systems. © 2011 World Scientific Publishing Company.

CASE OVERVIEW: This case challenges student to resolve FMCG Nigeria's trucking services-related problems in Nigeria, so as to be able not only to address immediate challenges (including truck availability in a disorganized environment as well as the cost and service quality of the needed trucking services) but also (and far more importantly, in the long run) to be able to double (over the next three years) the volume of the company's business in Nigeria. At first glance, the case looks as if it is all about trucking service contracts; in reality, however, it ends up being all about business process innovation and the importance of viewing challenges and opportunities within the context of a strategic vision for the company. The case is appropriate for senior-level undergraduates as well as students in MBA and Executive Development programs. It is designed to be taught in a one hour and a half class session, and is likely to require at least a couple hours of preparation by students. CASE SYNOPSIS: Mr. Henry Adjai is Supply Chain Manager for FMCG Nigeria, the Nigerian subsidiary of a multinational food manufacturer and marketer. Due to changes in the local environment, the cost of trucking services in Nigeria has increased by as much as 30%. Because FMCG Nigeria already spends more than one billion naira per year on trucking services, and because the company has very aggressive growth plans for its business in Nigeria, and because the company is now in the process of receiving bids from trucking companies to provide trucking services to FMCG Nigeria for the next three years, the Managing Director (M.D.) of FMCG Nigeria has asked Mr. Adjai to develop (as a matter of great urgency) a solution to the trucking servicesrelated problems and opportunities facing FMCG Nigeria.

Background: Large-scale biological jobs on high-performance computing systems require manual intervention if one or more computing cores on which they execute fail. This places not only a cost on the maintenance of the job, but also a cost on the time taken for reinstating the job and the risk of losing data and execution accomplished by the job before it failed. Approaches which can proactively detect computing core failures and take action to relocate the computing core[U+05F3]s job onto reliable cores can make a significant step towards automating fault tolerance. Method: This paper describes an experimental investigation into the use of multi-agent approaches for fault tolerance. Two approaches are studied, the first at the job level and the second at the core level. The approaches are investigated for single core failure scenarios that can occur in the execution of parallel reduction algorithms on computer clusters. A third approach is proposed that incorporates multi-agent technology both at the job and core level. Experiments are pursued in the context of genome searching, a popular computational biology application.Result: The key conclusion is that the approaches proposed are feasible for automating fault tolerance in high-performance computing systems with minimal human intervention. In a typical experiment in which the fault tolerance is studied, centralised and decentralised checkpointing approaches on an average add 90% to the actual time for executing the job. On the other hand, in the same experiment the multi-agent approaches add only 10% to the overall execution time. © 2014 Elsevier Ltd.

Robotics systems are a recognised part of the human exploration and colonisation of space. Advances in sensor and robotic networks, ambient intelligence and multi-agent systems offer approaches to modelling, implementing and operating robotic ecologies, comprising heterogeneous sets of mobile and embedded robotic devices and sensors, to support space applications, particularly in constructing and maintaining human habitats prior and subsequent to human arrival. This paper proposes a framework for integrating these technologies and techniques. The framework comprises application-level and infrastructure-level components, the former emphasising a model-driven approach supporting cognitive awareness and the latter an autonomic computing approach to self management. The paper provides a first draft of the framework, motivated by a deep space human outpost mission scenario. © 2012 IFAC.
