New Ways of Looking at the State Apparatus and the State Archive in Nineteenth Century Ireland: Curiosities from that Phonetic Museum - Royal Irish Constabulary Reports and their Political Uses, 1879-91

This essay seeks to contextualise the intelligence work of the Royal Irish Constabulary, particularly in the 1880s, in terms of the wider British and imperial practice and, as a corollary, to reflect upon aspects of the structure of the state apparatus and the state archive in Ireland since the Union. The author contrasts Irish and British police and bureaucratic work and suggests parallels between Ireland and other imperial locations, especially India. This paper also defines the narrowly political, indeed partisan, uses to which this intelligence was put, particularly during the Special Commission of 1888 on 'Parnellism and crime', when governmentheld police records were made available to counsel for The Times. By reflecting on the structure of the state apparatus and its use in this instance, the author aims to further the debate on the governance of nineteenth-century Ireland and to explore issues of colonial identity and practice. The line of argument proposed in this essay is prefigured in Margaret O'Callaghan, British high politics and a nationalist Ireland: criminality, land and the law under Forster and Balfour (Cork, 199

The Soviet Union and the International Brigades, 1936-1939

The International Brigades are typically viewed as a fighting force whose impetus came from the Comintern, and thus from within the walls of the Kremlin. If the assumption is essentially correct, the broader relation between Stalin’s USSR and the IB has received little attention. This chapter constitutes an empirically-based study of the Soviet role not only in the formation of the IB, but of the Red Army’s collaboration with IB units, and Moscow’s role in the climax and denouement of the brigadistas’ Spanish experience. This study’s principal conclusion is twofold: First, that the creation and sustenance of the IB was part of Stalin’s goal of linking the Loyalist cause with that of the Soviet Union and international communism, a component of a larger geo-strategic gamble which sought to create united opposition to the fascist menace, one which might eventually bring Moscow and the West into a closer alliance. The second conclusion is that the IB, like the broader projection of Soviet power and influence into the Spanish theater, was an overly ambitious operational failure whose abortive retreat is indicative of the basic weakness of the Stalinist regime in the years prior to the Second World War.

Sporting with the Classics: The Latin Poetry of William Dillingham

Sporting with the Classics: The Latin Poetry of William Dillingham (2010) (back cover)

Dana Sutton, University of California:
‘The great merit of Estelle Haan's study is that she is willing to take Dillingham seriously as a poet. Her reproduction of his work, together with an English translation and very detailed studies of his individual poems have the combined effect of rescuing an interesting poet from near-total oblivion. This, in my opinion, is the finest thing a neo-Latin scholar can do, and Haan accomplishes her task with the same skill, sensitivity, and eloquence that have distinguished her studies of other neo-Latin poets of this period (Joseph Addison and Vincent Bourne). It is impossible not to react to this volume with extreme respect and appreciation’.

Gordon Campbell, University of Leicester:
‘Nothing substantial has ever been published on Dillingham, but with this volume we have a new corpus of poetry that intersects with the work of many other seventeenth-century neo-Latin and vernacular poets. Professor Haan’s scholarship is here (as always) placed at the service of the poet, and she leads the reader gently through the work of a new poet. Professor Haan is the most eminent and able neo-Latinist of her generation, and her scholarship never fails; sometimes it dazzles as in the chapters on the hangman's stone and on Renaissance topiary. Her research is always up-to-date, and her translations have a gracefulness that other laborers in the vineyard can only envy’.

William Herschel Telescope observations of distant comets

We present results from broad-band V- and R-filter observations obtained at the 4.2-m William Herschel Telescope on La Palma on 2002 July 12-14. A total of six comets were imaged, and their heliocentric distances ranged from 2.8 to 6.1 au. The comets observed were 43P/Wolf-Harrington, 129P/Shoemaker-Levy 3, 133P/Elst-Pizarro, 143P/Kowal-Mrkos, P/1998 U4 (Spahr) and P/2001 H5 (NEAT). A detailed surface brightness profile analysis indicates that three of the targeted comets (43P/Wolf-Harrington, 129P/Shoemaker-Levy 3 and P/1998 U4) were visibly active, and the remaining three comets were stellar in appearance. Further analysis shows that for the three `stellar-like' comets the possible coma contribution to the observed flux does not exceed 12.2 per cent, and in the case of comet 143P/Kowal-Mrkos the coma contribution is expected to be as low as 1 per cent, and so the resulting photometry most likely represents that of the projected nucleus surface. Effective radii for the inactive comets range from 1.02 to 4.56 km, and the effective radius upper limits for the active comets range from 1.94 to 4.15 km. We assume an albedo and phase coefficient of 0.04 and 0.035 mag deg-1, respectively, with the exception of comets 133P/Elst-Pizarro and 143P/Kowal-Mrkos for which phase coefficients were previously measured. These values are compared with previous measurements, and for comet 43P/Wolf-Harrington we find that the nucleus axial ratio a/b could be as large as 2.44. For the active comets we measured dust production levels in terms of the Af? quantity. Spectral gradients were extracted for two of the inactive comets from their measured broad-band colour indices, and compared with the rest of the comet population for which (V-R) colour and spectral gradient values exist. We find a spectral gradient for 143P/Kowal-Mrkos of 9.9 +/- 8.1 per cent/100 nm, which is very typical of Jupiter-family comets, the majority of which have reflectivity gradients in the range 0-13 per cent (100 nm)-1. The spectral gradient for comet 133P/Elst-Pizarro is amongst the bluest yet measured. We measure a (V-R) colour index value of 0.14 +/- 0.11 for the nucleus of 133P/Elst-Pizarro which is considerably lower than previous measurements. A possible explanation for this difference is considered.

Model selection approaches for non-linear system identification: a review

The identification of non-linear systems using only observed finite datasets has become a mature research area over the last two decades. A class of linear-in-the-parameter models with universal approximation capabilities have been intensively studied and widely used due to the availability of many linear-learning algorithms and their inherent convergence conditions. This article presents a systematic overview of basic research on model selection approaches for linear-in-the-parameter models. One of the fundamental problems in non-linear system identification is to find the minimal model with the best model generalisation performance from observational data only. The important concepts in achieving good model generalisation used in various non-linear system-identification algorithms are first reviewed, including Bayesian parameter regularisation and models selective criteria based on the cross validation and experimental design. A significant advance in machine learning has been the development of the support vector machine as a means for identifying kernel models based on the structural risk minimisation principle. The developments on the convex optimisation-based model construction algorithms including the support vector regression algorithms are outlined. Input selection algorithms and on-line system identification algorithms are also included in this review. Finally, some industrial applications of non-linear models are discussed.
