Analyses of the Provisional IRA in Northern Ireland tend to underplay the influence of political strategy in the 1970s, preferring to emphasise militarism. Similarly, the persistence of militarism in the 1980s is often obscured by the attention paid to a ‘new’ republican political orientation. This article seeks to draw attention to the IRA's evolving attitude to the ‘problem’ of Ulster unionism, and republicanism's various estimations of the likely efficacy of violence throughout the period. Republicanism is best understood as a deeply rooted working-class ethno-nationalist movement interacting closely with the other agents of the Northern Ireland conflict: constitutional nationalism, unionism and the British government. ‘Armed struggle’ became a declining asset for republicanism as it came to be seen less as a form of ‘popular guerrilla warfare’ and more as ‘terrorism’. 1 [1] For valuable advice, thanks to Prof. Roy Foster.

At many sites throughout the world rock art paintings have been covered by naturally deposited calcite laminations, which we demonstrate can be individually dated by recently improved uranium-series methods. Here we report the application of multi-collector inductively coupled plasma mass spectrometry to measure the ages for carbonate coatings that bracket red pigment at Lene Hara cave, East Timor, which could be evidence of human painting. These analyses establish the feasibility of dating milligram samples of finely layered calcite deposits associated with archaeological evidence of human occupation. In addition to confirming an age of less then 6300 years for the visible red paintings on the carbonate surface we also report a substantially older age of 24,000 to 29,300 years for a similar, older red pigment lamination providing possible evidence for an earlier painting episode.  相似文献

ABSTRACT

This article explores Clement Greenberg’s idea that abstraction is a form of negation in the context of mid-twentieth century homophobia and Jewish self-hatred. Greenberg presents both as a denial of the self, and so aligns the negation involved in abstraction with the self-liquidation necessary for economic progress in capitalism.  相似文献

Abstract

Experimental studies in the localisation of brain function did not begin with Flourens, nor did clinical studies with the phrenologists or physicians like Auburtin, Bouillaud, or Dax, shortly afterward. Although the pre‐1820 literature is moderate, some of it is worth examining because of the problems associated with interpreting it.

There are three separate but related problems: philosophical, methodological, and conceptual. Philosophically, whether one saw the brain as the main organ of sensibility, as did the Hippocratic writers and Galen, or the heart, as did Aristotle, determined the attention given to the brain. The methodological problems arose from the gross structure of the brain not being immediately obvious and the dominant technique of dissecting the brain in transverse sections revealing the ventricles and their immediately associated structures more readily than other structures. Conceptually, the ventricles were seen as the sites through which sensations were transferred to the muscles. Observations relevant to localisation were thus related to the ventricles or to structures lying outside the cerebrum.

What are now considered major structural landmarks were not discovered until late: the Sylvian fissure in about 1640 and the fissure of Rolando in 1829, the former being dependent on new methods of dissection. In general, it was not until the first half of the nineteenth century that the cerebral structures were properly differentiated. Consequently, calls for comparative clinical studies of the effects of lesions in different parts of the brain inevitably fell on ears tuned to a framework which could not incorporate them. So, did the results of the earlier experimental studies.  相似文献
