Two types of nursing theory are described: the realistic, whose purpose is to account for the complex reality of nursing; and the idealistic, whose purpose is to describe an idealised world of nursing as it ‘ought to be’.

It is argued that British... Read More about The ideal and the real: some thoughts on theoretical developments in British nursing.

Cartographic Algorithms: Problems of Implementation and Evaluation and the Impact of Digitising Errors (1991)

Cartographic generalisation remains one of the outstanding challenges in digital cartography and Geographical Information Systems (GIS). It is generally assumed that computerisation will lead to the removal of spurious variability introduced by the s...

The primary aim of this paper is to illustrate the value of visualization in cartography and to indicate that tools for the generation and manipulation of realistic images are of limited value within this application. This paper demonstrates the valu... Read More about The Douglas-Peucker algorithm for line simplification: Re-evaluation through visualization.

The paper starts with a brief introduction to cartography and cartographic maps. It then pro... Read More about Trends and concerns in digital cartography.

Approaches to the optimizing control problem (1988)
Journal Article
Ellis, J. E., Kambhampati, C., Sheng, G., & Roberts, P. D. (1988). Approaches to the optimizing control problem. International Journal of Systems Science, 19(10), 1969-1985. https://doi.org/10.1080/00207728808964092

The selection of the steady-state controls which enable a system to operate in an optimum manner is the optimizing control problem. An examination of direct and adaptive model-based approaches to this problem is made. In the direct approach, system m... Read More about Approaches to the optimizing control problem.

The protestant episcopal church, black nationalists, and expansion of the west african missionary field, 1851–1871 (1988)
Journal Article

One of the most boldly conceived assaults on benighted Africa during the nineteenth century was that undertaken by mainline Protestant denominations in the United States. With the brash confidence characteristic of the age, hundreds of American missi...

The signed Chi-score measure for the classification and mapping of polychotomous data (1981)
Journal Article

Several polychotomous characteristics, when expressed in chi-score form, exhibit distributions in property space which deviate from the inherent assumptions of the more commonly used methods of cluster analysis. This paper suggests a novel approach t... Read More about The signed Chi-score measure for the classification and mapping of polychotomous data.
