J. M. F. Wright and Newton's method of first and last ratios
No full textWe describe the approach taken by the nineteenth-century Cambridge textbook author J. M. F. Wright to a notoriously difficult part of Newton’s Principia: the method of first and last ratios. Wright suggested an algebraic point of view that, to his mind, would not only remove all prior confusion over the method, but would also serve as a new foundation for calculus as a whole. We examine the details of Wright’s approach, and discuss whether it was as successful as he claimed it to be
Donkeys and Hares. The Enemy Warrior in the Early European Chronicles of the Conques
No full textThe Author scrutinizes the image of the enemy warrior in the early European chronicles of the Spanish conquest, within a historical-comparative approach. In the 16th century sources the image of the Indios fighting Europeans offers a very specific vision of this enemy. It was an image that had its roots in stereotypes of the past. But it had been reshaped into a new and original version. Solidarity between the devil and the Indios did not produce fearsome warriors. It was an image that did not have to hinder the expansion of European traffic

The limits of HRM in a new era of work: Bezonomics and the Amazon Effect
No full textThere can be little doubt that the risk and fluctuation of demand taken on
by employers has been increasingly passed onto employees. We are witnessing a fragmented contract of rules largely determined by employers, for employers. Here the conventional form of employment relations is nonunionism and the management of employees through Human Resource Management (HRM). This chapter critically reviews the underlying assumptions underpinning the rise of HRM, not least its unitarist undercurrent, narrow emphasis on performance and limited incorporation of multiple stakeholders. The chapter then uses Amazon as an exemplary case to illuminate these dynamics in practice and to offer a critical review of what constitutes a meaningful and successful organisation in this new era of work. The chapter concludes by detailing prospects for redress and institutional experimentation, including via technological platforms

Living on the slippery slope : the nature, sources and logic of vagueness
No full textAccording to the dominant approach in the theory of vagueness, the nature of the vagueness of an expression ‘F’ consists in its presenting borderline cases in an appropriately ordered series: objects which are neither definitely F nor definitely not F (where the notion of definiteness can be semantic, ontic, epistemic, psychological or primitive). In view of the various problems faced by theories of vagueness adopting the dominant approach, the thesis proposes to reconsider the naive theory of vagueness, according to which the nature of the vagueness of an expression consists in its not drawing boundaries between any neighbouring objects in an appropriately ordered series. It is argued that expressions and concepts which do present this feature play an essential role in our cognitive and practical life, allowing us to conceptualize—in a way which would otherwise be impossible—the typically coarse-grained distinctions we encounter in reality. Despite its strong initial plausibility and ability to explain many phenomena of vagueness, the naive theory is widely rejected because thought to be shown inconsistent by the sorites paradox. In reply, it is first argued that accounts of vagueness based on the dominant approach are themselves subject to higher-order sorites paradoxes. The paradox is then
solved on behalf of the naive theory by rejecting the unrestricted transitivity of the consequence relation on a vague language; a family of logics apt for reasoning with vague expressions is proposed and studied (using models
with partially ordered values). The characteristic philosophical and logical consequences of this novel solution are developed and defended in detail. In particular, it is shown how the analysis of what happens in the attempt of surveying a sorites series and deciding each case allows the naive theory to recover a "thin" notion of a borderline case.Funding provided by an AHRC Fellowship and a Jacobsen Fellowship from The Royal Institute of Philosoph
Twentieth-century poetry and science : science in the poetry of Hugh MacDiarmid, Judith Wright, Edwin Morgan, and Miroslav Holub
No full textThe aim of this thesis is to arrive at a characterisation of twentieth century poetry and science by means of a detailed study of the work of four poets who engaged extensively with science and whose writing lives spanned the greater part of the period. The study of science in the work of the four chosen poets, Hugh MacDiarmid (1892 – 1978), Judith Wright (1915 – 2000), Edwin Morgan (1920 – 2010), and Miroslav Holub (1923 – 1998), is preceded by a literature survey and an initial theoretical chapter. This initial part of the thesis outlines the interdisciplinary history of the academic subject of poetry and science, addressing, amongst other things, the challenges presented by the episodes known as the ‘two cultures’ and the ‘science wars’. Seeking to offer a perspective on poetry and science more aligned to scientific materialism than is typical in the interdiscipline, a systemic challenge to Thomas Kuhn’s The Structure of Scientific Revolutions (1962) is put forward in the first chapter. Additionally, the founding work of poetry and science, I. A. Richards’s Science and Poetry (1926), is assessed both in the context in which it was written, and from a contemporary viewpoint; and, as one way to understand science in poetry, a theory of the creative misreading of science is developed, loosely based on Harold Bloom’s The Anxiety of Influence (1973). The detailed study of science in poetry commences in Chapter II with Hugh MacDiarmid’s late work in English, dating from his period on the Shetland Island of Whalsay (1933 – 1941). The thesis in this chapter is that this work can be seen as a radical integration of poetry and science; this concept is considered in a variety of ways including through a computational model, originally suggested by Robert Crawford. The Australian poet Judith Wright, the subject of Chapter III, is less well known to poetry and science, but a detailed engagement with physics can be identified, including her use of four-dimensional imagery, which has considerable support from background evidence. Biology in her poetry is also studied in the light of recent work by John Holmes. In Chapter IV, science in the poetry of Edwin Morgan is discussed in terms of its origin and development, from the perspective of the mythologised science in his science fiction poetry, and from the ‘hard’ technological perspective of his computer poems. Morgan’s work is cast in relief by readings which are against the grain of some but not all of his published comments. The thesis rounds on its theme of materialism with the fifth and final chapter which studies the work of Miroslav Holub, a poet and practising scientist in communist-era Prague. Holub’s work, it is argued, represents a rare and important literary expression of scientific materialism. The focus on materialism in the thesis is not mechanistic, nor exclusive of the domain of the imagination; instead it frames the contrast between the original science and the transformed poetic version. The thesis is drawn together in a short conclusion
