Pathogens that are transmitted between wildlife, livestock and humans present major challenges for the protection of human and animal health, the economic sustainability of agriculture, and the conservation of wildlife. Mycobacterium bovis, the aetiological agent of bovine tuberculosis (TB), is one such pathogen. The incidence of TB in cattle has increased(More)
A case-control study of the factors associated with the risk of a bovine tuberculosis (TB) breakdown in cattle herds was undertaken within the randomized badger culling trial (RBCT). TB breakdowns occurring prior to the 2001 foot-and-mouth disease epidemic in three RBCT triplets were eligible to be cases; controls were selected from the same RBCT area. Data(More)
Online education is established, growing, and here to stay. It is creating new opportunities for students and also for faculty, regulators of education, and the educational institutions themselves. Much of what is being learned by the practitioners will flow into the large numbers of blended courses that will be developed and delivered on most campuses.(More)
This research investigated the effects of applying intelligent agent techniques to an online learning environment. The knowbots (or Knowledge Robots) created for the research were intelligent software agents that automated the repetitive tasks of human facilitators in a series of online workshops. The study specifically captured experimental results of(More)
Vanderbilt University Medical Center is implementing an Integrated Advanced Information Management System (IAIMS) using a fast-track approach. The elapsed time between start-up and completion of implementation will be 7.5 years. The Start-Up and Planning phases of the project are complete. The Implementation phase asks one question: How does an organization(More)
The Independent Scientific Group on Cattle TB was appointed by the Government in 1998 to implement and develop the research recommendations of the 1997 Krebs report on bovine tuberculosis in cattle and badgers. In this article, members of the group discuss the approach they are adopting in attempting to ensure that future control strategies are(More)
Horseradish peroxidase labelled antisera to pig immunoglobulins IgA, IgG and IgM were used to study the distribution of immunoglobulins and immunoglobulin-containing cells in pig tissues. The immunoperoxidase technique was used in an attempt to overcome the problems of non-specificity of the immunofluorescent technique, and has been found to have(More)
Since 1950, Alberta Agriculture has supervised and coordinated a rural-based Norway rat (Rattus norvegicus) control program that has essentially kept the province rat-free. Success is achieved by eliminating invading rats within a control zone 600 km long and 30 km wide along the eastern border of the province. A systematic detection and eradication system(More)
