The pathogenesis of migraine - 17th to early 20th Century understandings

The modern understanding of the pathogenesis of migraine, based on the concept that it is a neurovascular disorder, is often thought to have emerged from the work of Harold Wolff in the period 1932-1962. However, over the preceding 300 years, from William Harvey onwards, various hypotheses of the pathogenesis of migraine had been proposed, a few bearing reasonably strong resemblances to Wolff's ideas, though based on less adequate evidence. Many of these earlier hypotheses regarded migraine either primarily as a vascular (e.g., Willis, Wepfer, Latham) or as a neural disorder (e.g., Harvey, Lieving and his 'nerve storms'). There were also variations around these two major themes and in the 19th Century a number of neurovascufar type hypotheses emerged assigning a major role in migraine pathogenesis to the autonomic nervous system. In addition, during the three centuries there were a number of other hypotheses based on different postulated pathogenic mechanisms, some quite ingenious, which had relatively brief vogues. No hypothesis has yet proved capable of explaining all the features of migraine satisfactorily. (c) 2005 Elsevier Ltd. All rights reserved.

Delivering demons punishing wives: False imprisonment, exoricism and other matrimonial duties in a late 20th-century manslaughter case

This article provides an analysis of R v Vollmer and Others, Australia’s most famous ‘exorcism-manslaughter’ case, in which a woman, Joan Vollmer, underwent an ‘exorcism’ performed by four people, resulting in her death. We examine how taken-for-granted distinctions were collapsed during the resulting trial - distinctions between crime and punishment, exorcism and punishment, church and state, the past and the present, law and religion, reason and unreason and between a demon and a woman. We show how the defence argument for the reality of demonic possession normalized the bizarre, while simultaneously exoticizing the mundane or ‘traditional’ criminal case involving a husband defendant and a dead wife. The apparent assumption on the part of the police and the media that this case was bizarre serves to veil the fact of its relative ordinariness. A wife is killed, and the lethal punishing violence inflicted on her body downplayed, to be reinterpreted in the legal context as somehow a consequence of something she herself precipitated. Our analysis of the Vollmer case provides a novel perspective on that always intriguing conundrum of crime and punishment.

The imaging of Samoa in illustrated magazines and serial encyclopedias in the early 20th-century

Drawing on English language sources and material relating to the colonial administrations of Western Samoa (now Samoa) and American Samoa, this examination of photographically illustrated serial encyclopaedias and magazines proposes an alternative historical analysis of the colonial imaging of Samoa, the most extensively covered field in Oceanic photographic studies. Though photographs published between 1890s and World War II were often 'recycled', without acknowledging the fact that they were taken much earlier, and despite claims in the text of illustrated publications of an unchanged, enduring, archaic tradition in Samoa, the amazing variety of photographic content often offered contradictory evidence, depicting a modern, adaptive and progressive Samoa. Contrary to orthodox historical analysis, the images of Samoa in illustrated magazines and encyclopaedias were not limited to a small repetitive gallery of partially clothed women and costumed chiefs; and the ways in which readers understood Samoa from photographs and text raises questions still to be explored.

Digitisation and Presentation of Historical Materials in a Virtual Exhibition ‘The Image of India in Bulgaria: from the late 19th to the late 20th Century’

The main contribution of this project is the study of collections of valuable documents related to the image of India in Bulgaria. Digital repositories of selected samples are constructed using modern information technologies. The results are presented in a virtual exhibition ‘The Image of India in Bulgaria: from the late 19th to the late 20th century’.

40 20th Century Spanish Sculptresses

This article presents a compilation of female artists who carried out their sculptural work during the twentieth century. With a brief presentation of each of them I want to implement visibility and the importance of incorporating their works to the collective imagery in order to be added to Spanish contemporary arts history. Some of them have public monuments of great popular recognition but their names have not been mentioned yet. Some others have “minor” works but they were relevant teachers to other artists. A few of them have extensive monographs about their life and their works. While others have almost gone unnoticed, but the proof of their professional career’s existence seems fundamental to us and they must be incorporated to history either through text books, university research works, ideally achieving a supported research project, to provide them the visibility their works and their vital trajectories deserve.

Presence and possible cause of periodicities in 20th-century extreme coastal surge: Belfast Harbour, Northern Ireland.

Identifying 20th-century periodic coastal surge variation is strategic for the 21st-century coastal surge estimates, as surge periodicities may amplify/reduce future MSL enhanced surge forecasts. Extreme coastal surge data from Belfast Harbour (UK) tide gauges are available for 1901–2010 and provide the potential for decadal-plus periodic coastal surge analysis. Annual extreme surge-elevation distributions (sampled every 10-min) are analysed using PCA and cluster analysis to decompose variation within- and between-years to assess similarity of years in terms of Surge Climate Types, and to establish significance of any transitions in Type occurrence over time using non-parametric Markov analysis. Annual extreme surge variation is shown to be periodically organised across the 20th century. Extreme surge magnitude and distribution show a number of significant cyclonic induced multi-annual (2, 3, 5 & 6 years) cycles, as well as dominant multi-decadal (15–25 years) cycles of variation superimposed on an 80 year fluctuation in atmospheric–oceanic variation across the North Atlantic (relative to NAO/AMO interaction). The top 30 extreme surge events show some relationship with NAO per se, given that 80% are associated with westerly dominant atmospheric flows (+ NAO), but there are 20% of the events associated with blocking air massess (− NAO). Although 20% of the top 30 ranked positive surges occurred within the last twenty years, there is no unequivocal evidence of recent acceleration in extreme surge magnitude related to other than the scale of natural periodic variation.
