The Korean War and the Post-war Prisoner of War Regime, 1945–1956

This paper examines the framework for the treatment of prisoners of war that emerged after 1945. It focuses on one of the key elements of the post-war prisoner of war (POW) regime, the role of neutral bodies – state authorities acting as ‘protecting powers’ or humanitarian agencies such as the International Committee of the Red Cross – in supervising the implementation of the 1949 POW convention. It examines the importance of neutral supervision for the POW regime, and shows how the events of the Korean War affected the willingness of states to comply with their obligations under the new convention

Fearing for Merseyside: Liverpool and the French Invasion Scare of 1858-1859'

From the spring of 1858 to the winter of 1859, Britain was gripped by fears of a French invasion. These were prompted by a fraying of Anglo-French relations, following the attempted assassination of the French Emperor Napoleon III by a group of revolutionaries that included British citizens. The fear that Napoleon might take military action against Britain in response first arose in the spring of 1858, whereafter the national feeling intensified over the summer of 1859, when the emperor launched a successful invasion of Italy, raising the spectre of Britain having to deal with a new Bonaparte who could match his famous namesake both ambition and martial ability. The purpose of this article is to re-assess the French invasion scare of 1858–59, focusing on how the fear was both nurtured and responded to, not at a national, but at a local, level. Specifically, the focus here is on one of Britain’s key port cities, Liverpool which, as a maritime and commercial centre, seemed to many on Merseyside as a probable target for a waterborne attack. By analysing how the press and public of the greater Merseyside region responded to this perceived threat, this article sheds light on the division between fears and reality in public perceptions, and the understudied, localised reaction of Liverpudlians to this apparent national crisis

Radical Warfare’s First “Superweapon”: The Fears, Perceptions and Realities of the Orsini Bomb, 1858-1896

This article retraces the forgotten legacy of a percussion triggered shrapnel scattering improvised explosive device (IED), known as the Orsini Bomb. Initially used in an attempt to assassinate Emperor Napoleon III in 1858, in the decades after, the Orsini Bomb was replicated, modified and deployed by regicides, insurgents and terrorists, and mythologised by the press as an omnipresent aspect of such forms of radical warfare. This article presents a ‘biography’ of this unique IED, concluding, firstly, that Orsini’s design was an important point of reference in weapons manufacture for violent radicals even after the advent of dynamite in the 1860s and,secondly, that its reputation as a semiotic reference point for terrorist activity was enhanced by press reportage of its proliferation and use throughout the fin de siècle. In the final analysis, the Orsini Bomb became a transnationally recognised ‘brand’ of weapon, synonymous with both assassination and insurgency. As such, the bomb’s reputation – often dwarfed in the historiography of political violence by dynamite – needs to be reconsidered

Seabirds enhance coral reef productivity and functioning in the absence of invasive rats

Biotic connectivity between ecosystems can provide major transport of organic matter and nutrients, influencing ecosystem structure and productivity1, yet the implications are poorly understood owing to human disruptions of natural flows2. When abundant, seabirds feeding in the open ocean transport large quantities of nutrients onto islands, enhancing the productivity of island fauna and flora3,4. Whether leaching of these nutrients back into the sea influences the productivity, structure and functioning of adjacent coral reef ecosystems is not known. Here we address this question using a rare natural experiment in the Chagos Archipelago, in which some islands are rat-infested and others are rat-free. We found that seabird densities and nitrogen deposition rates are 760 and 251 times higher, respectively, on islands where humans have not introduced rats. Consequently, rat-free islands had substantially higher nitrogen stable isotope (δ15N) values in soils and shrubs, reflecting pelagic nutrient sources. These higher values of δ15N were also apparent in macroalgae, filter-feeding sponges, turf algae and fish on adjacent coral reefs. Herbivorous damselfish on reefs adjacent to the rat-free islands grew faster, and fish communities had higher biomass across trophic feeding groups, with 48% greater overall biomass. Rates of two critical ecosystem functions, grazing and bioerosion, were 3.2 and 3.8 times higher, respectively, adjacent to rat-free islands. Collectively, these results reveal how rat introductions disrupt nutrient flows among pelagic, island and coral reef ecosystems. Thus, rat eradication on oceanic islands should be a high conservation priority as it is likely to benefit terrestrial ecosystems and enhance coral reef productivity and functioning by restoring seabird-derived nutrient subsidies from large areas of ocean

Effects of electric-field shape and frequency on smectic layer rotation of siloxane ferroelectric liquid crystals

Smectic layer rotations in ferroelectric liquid crystals (FLC) upon application of electric fields have been observed only in chiral smectic phases and believed to be related to the electroclinic effect. In this article, effects of electric field shape and frequency on smectic layer rotations in siloxane-based FLCs were investigated by applying various kinds of asymmetric ac waveforms for a range of frequencies and temperatures. For a given peak voltage, we have found that the asymmetry was one of the most important parameters and demonstrated that the modified step form showed the best efficiency for smectic layer rotations

Fifty years of Harper-Dorn creep: a viable creep mechanism or a Californian artifact?

Fifty years ago, in a series of classic creep experiments conducted at the University of California in Berkeley, Harper and Dorn obtained unique experimental data revealing the possibility of a new and heretofore unrecognized flow process occurring in pure aluminum when tested at low stresses and at temperatures very close to the melting temperature. This flow mechanism, subsequently designated Harper–Dorn creep, has been the center of much argument and speculation in the ensuing years. The present paper looks back over the last half-century and charts the various developments in attempts to obtain a more detailed understanding of whether Harper–Dorn creep is (or is not) a viable creep process. Examples are presented for both metals and non-metals. It is concluded that, although it appears Harper–Dorn creep may occur only under restricted conditions associated with high purity materials and low initial dislocation densities, nevertheless there is good evidence supporting the validity of this creep mechanism as a viable and unique flow process
