Background Nigeria accounts for a significant proportion of global maternal mortality figures with little progress made in curbing poor health indices. In a bid to reverse this trend, the Government of Nigeria initiated a conditional cash transfer (CCT) programme to encourage pregnant women utilize services at designated health facilities. This study aims to understand experiences of women who ...

SUMMARY In this paper we describe a software subsystem that can be added to each of a set of physically interconnected UNIX or UNIX look-alike systems, so as to construct a distributed system which is functionally indistinguishable at both the user and the program level from a conventional single-processor UNIX system. The techniques used are applicable to a variety and multiplicity of both loc...

Two design rules which aid the construction of distributed computing systems and the provision of fault tolerance are described, namely that: (i) a distributed computing system should be functionally equivalent to the individual computing systems of which it is composed, and (ii) fault tolerant systems should be constructed from generalised fault tolerant components. The reasoning behind these ...

For the development of eficient parallel applications, fast but reliable performance predictions are essential. Many existing modelling formalisms are either not directly suited to model parallel applications, or too expensive. This paper describes several extensions and improvements to a previously introduced methodology, based on an extension of queueing networks. The set of machine model bui...

A major debate in the international marketing literature deals with the globalization of markets and the extent to which a company’s international marketing strategy can be standardized (Buzzell, 1968; Cavusgil et al., 1993; Douglas and Wind, 1987; Hill and Still, 1984; Jain, 1989; Levitt, 1983; Sorenson and Wiechmann, 1975). Significant progress has been made with respect to the extent to whic...

The aim of this thesis was to study potential breeding strategies for indigenous livestock in Eastern and Southern Africa under low input production systems. The thesis covered a study of the status of supportive infrastructure for use of animal genetic resources. The case of Red Maasai sheep was studied as a model for design of strategies for improvement of an indigenous breed under threat. St...

invasive meningococcal disease (imd) is a severe bacterial infectious disease with high mortality and morbidity rates worldwide. in recent years, industrialised countries have implemented vaccines targeting imd in their national immunisation programmes (nips). in 2002, the netherlands successfully implemented a single dose of meningococcal serogroup c conjugate vaccine at the age of 14 months a...

Practitioner research is now long established as a means of professional development for academics in higher education, resulting in well documented benefits for the practitioner researcher and their students. What is less well documented is the process by which individual academic members of staff develop as practitioner researchers and how their engagement with the realities of practice and r...

Identifying high cognitive complexity modules can lead to a better quality software system and can help during maintenance also. It has been found that inheritance has an impact on cognitive complexity of a software system. In this paper, two inheritance metrics based on cognitive complexity, one at class level CCI (Class Complexity due to Inheritance) and another at program level ACI (Average ...

The Farmers of the Future (FoF) initiative implemented a programme of integrating natural resources management in the basic education curriculum. The purpose of the study was to document activities and determine the effects of FoF programme on primary school learners’ perceptions towards natural resources management by comparing learners involved in the FoF programme and those not involved. Fur...
