Gerald Midgley examines the arguments presented by Jeffrey Gray, Peter Singer and Richard Ryder in our special issue on animal experimentation (May 1991). He proposes a contextual theory of moral choice to deal with the conflicting ethical principles... Read More about A Contextual View of Ethics.

Line generalisation by repeated elimination of points (1993)
Journal Article
Visvalingam, M., & Whyatt, J. D. (1993). Line generalisation by repeated elimination of points. The Cartographic journal, 30(1), 46-51. https://doi.org/10.1179/000870493786962263

This paper presents a new approach to line generalisation which uses the concept of ‘effective area’ for progressive simplification of a line by point elimination. Two coastlines are used to compare the performance of this, with that of the widely us... Read More about Line generalisation by repeated elimination of points.

Nonlinear identification of the Pco2control system in man (1993)

Quality of life as quality of being: an alternative to the subject-object dichotomy (1992)
Journal Article

The opening section of this paper is concerned with certain questions concerning the concept ‘quality of life’ Is it possible for one person to make judgements about the quality of life of another? If it is possible, then is it morally acceptable? Gi... Read More about Quality of life as quality of being: an alternative to the subject-object dichotomy.

The London Committee and mobilization of public opinion against the slave trade (1992)

During the late eighteenth century organized anti-slavery, in the shape of the campaign to end the African slave trade (1787–1807), became an unavoidable feature of political life in Britain. Drawing on previously unpublished material in the Josiah W... Read More about The London Committee and mobilization of public opinion against the slave trade.

Cancer mortality in the first degree relatives of young breast cancer patients (1992)
Journal Article

Significantly increased breast cancer mortality was observed below age 60 (30 deat... Read More about Cancer mortality in the first degree relatives of young breast cancer patients.

The ideal and the real: some thoughts on theoretical developments in British nursing (1991)

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.
