The role of game animals as important hosts of some species of tsetse, including Glossina pallidipes, has been studied in detail in the Lambwe Valley area of Kenya. A large population of G. pallidipes existed in association with a varied community of game animals in the study area, and the investigation was designed to determine which of the hosts available(More)
In invasion processes, both abiotic and biotic factors are considered essential, but the latter are usually disregarded when modeling the potential spread of exotic species. In the framework of set theory, interactions between biotic (B), abiotic (A), and movement-related (M) factors in the geographical space can be hypothesized with BAM diagrams and tested(More)
History of distance learning dates back to the late 1960's. However with the advent of the Internet it was repositioned as a major tool for course delivery so that students who are physically prevented from attending class room settings can undertake learning within a setting of their choice aligned with a pace that they can easily cope with.

This paper presents evidence that tsetse flies (Glossina) can be dispersed by wind. This dispersal in West Africa is suggested to be along a south-west north-east axis. The implications of wind dispersal of Glossina for chemical and genetic control operations is discussed. Field experiments necessary to test this hypothesis are recommended. A study of human(More)
This paper is about performance evaluation in facilities management. It identifies the Balanced Scorecard as a widely used management framework for optimal measurement of organisational performance, discusses the fundamental points to cover in its implementation a nd describes the application which translates an organisation's mission and strategy into a(More)
Describes a process to assess facilities management (FM) process capabilities: the structured process improvement for construction environments--facilities management (SPICE FM) approach. The SPICE FM framework is a method that FM organizations can use to monitor continuously and subsequently improve their performance. The SPICE FM framework is being tested(More)
The higher education system in the UK has significantly changed over the last decade due to a growing emphasis on student learning activities, quality assurance procedures and research funding mechanisms. According to previous studies, there is no automatic link between research and teaching. Thus, the link needs to be created to enhance staff productivity(More)

Several thousand Glossina pallidipes flies were dissected to determine trypanosome infection rates in the Lambwe Valley and to collect information on the hosts of this tsetse. A total of 1 450 (19.3%) flies had mature trypanosome infections but the rate varied between 9.6% and 30.9% in the Lambwe Valley. In the Roo Valley the rate was 19.7-28.6%. Blood-meal(More)
