Organic farmers have taken a lead in attempting to reduce dependence on pharmaceutical control of parasites in farmed livestock. Focussing on management and nutrition, the objective of this research is to further develop control strategies, which can support and increase the flexibility of clean grazing systems for sheep and cattle. The approach has been to combine on-farm epidemiological studi...

BACKGROUND Heart failure (HF) is a devastating disease with increasing prevalence in elderly populations. One-half of all patients die within 5 years of diagnosis. The annual cost of treating patients with HF in the US is more than $20 billion, which is estimated to be greater than that of myocardial infarction and all cancers combined. Given the complex pathophysiology and varied manifestation...

An organization’s strategies for managing Geographic Information Systems (GIS) play a crucial role in the success of the technology within the organization. As with any technological innovation, the key factor in GIS success is how it is applied to solve the organization’s business problems. Corporatewide strategies to introduce, implement, and operate the GIS determine how well it serves busin...

While organisations recognise that Knowledge Management (KM) is essential for improving performance, many have difficulties in developing strategies for implementation. The nature of knowledge is of particular complexity in organisations such as those within the construction industry characterised by temporary ‘virtual’ organisations formed for the completion of projects. A significant proporti...

BACKGROUND In the current treatment paradigms for leukemias, hematopoietic stem cell transplant (HSCT) is considered the best option with a curative potential although more often than not it simply delays disease progression. Advances are needed, both in current therapies and in the development of new strategies. Partly from studying the nuances of the curative potential of stem cell transplant...

“Food production and distribution in South Africa, as in most other countries, is undergoing major structural changes caused by changing and diverse consumer demands, new technologies (e.g. bioand information technologies), new product characteristics, changing firm sizes and more exposure to world markets... the structural realignment in agriculture and the formation of new supply chains are p...

Trial therapies for rare cancers are usually selected empirically and often fail during clinical testing. The poor efficiency and limited success of this process is hampered by a lack of accurate models with which to perform preclinical studies, and small patient numbers that are likely to include distinct subtypes. These challenges are further compounded by increasing evidence that many cancer...

We describe ongoing developments on two offline strategies for automatically answering questions in the medical domain: one based on an analysis of the document structure, the other based on dependency parsing. We highlight differences with open domain question answering, and provide a preliminary evaluation of the current state of our strategies.

In 1974, the major leverage point in the software process is at the software design and structuring stage. This stage begins with a statement of software requirements. Properly done, the software design and structuring process can identify the weak spots and mismatches in the requirements statement which are the main sources of unresponsiveness of delivered software. Once these weak spots slip ...

This tutorial provides an overview of the PVS strategy language, and explains how to define new PVS strategies and load them into PVS, and how to create a strategy package. It then discusses several useful techniques that can be used in developing user strategies, and provides examples that illustrate many of these techniques.
