A new set of corrected geomagnetic coordinates (CGM) has been calculated from the magnetic field model DGRF for Epoch 1985 and the IGRF model for Epoch 1990. A new approach to determine the ‘dip’ magnetic equator has been developed, which is based on the vertical (along Re) projection on the Earth's surface of the B-minimum value point (apex) on each geomagnetic field line. A strip along the ‘dip’ magnetic equator line has been defined where the corrected geomagnetic coordinates could not be found by the definition of CGM. Linear interpolation between the locations of the two last definable CGM latitudes in both hemispheres has been used to calculate the CGM longitudes in the equatorial region. Interpolation between locations of the last definable CGM latitude and ‘dip’ equator in both hemispheres has been used to calculate the CGM latitudes in this region. The constant B-min geomagnetic coordinate system (CBM) is proposed and analysed to replace CGM in the equatorial region.  相似文献

The concept of the extrapyramidal system comprises an amalgam of disparate and often conflicting ideas with a tortuous history. To the theoretical neuroscientist or practicing clinician, it promptly evokes semantic associations that are hardly reminiscent of its original meaning. The purpose of this article is to revisit the sources of the extrapyramidal concept and to examine the transformations that it went through from its inception, in the late 1890s, up to the neuroimaging revolution of the 1980s. Our review shows that the use of "extrapyramidal" as a surrogate for the basal ganglia, disorders of movement, or certain manifestations of spastic hemiplegia does not apply to humans; rather, it represents the historical product of the unwarranted translation of results of animal experimentation into the interpretation of clinical findings on human patients, misguided clinico-anatomic deductions, and fanciful phylogenetic notions. We conclude that the extrapyramidal concept is a valid and robust anatomic concept as long as it strictly refers to the collection of descending fibers originating in a few discrete brainstem tegmental motor nuclei that project to the spinal cord.  相似文献

Abstract

This article analyses the political and social changes that occurred in Italy in the 1980s and 1990s in ways that bring economic and sociological models together in a historical perspective. It argues that the rise of the new Right following the disintegration of the Christian Democrats and the Socialist Party was the result not only of the changed international situation (which was none the less important) but of the changes that had been taking place within the Italian political parties and the growing importance of neo‐patrimonial tendencies over the previous fifteen years. Increasingly open forms of corruption (on the part of the political classes rather than the industrial bourgeoisie, even though they too were to some extent accomplices) are interpreted as a sign of the crisis and disintegration of the political system that had taken shape in the postwar period. Hence the nexus of anguish and politics for both the upper classes and the rest of Italian society that has become one of the most important features of the situation in Italy today.  相似文献

2002年的仲夏,骄阳似火;2002年的初秋,阴雨连绵。配合国家重点工程——西气东输项目山西段的考古发掘是在2002年夏天的高温酷暑中开始的,结束田野工作时已经是仲秋时节。对于所有参加配合西气东输项目建设的工作人员来说,这都是一段难以忘怀的经历。在田野发掘期间,我们以高度负责的精神全身心地投入到工作当中,东西奔波于崇山峻岭、丘陵沟壑、河旁台地,甚至无暇整理一下自己的思路。当这次艰巨的田野发掘工作终于告一段落,我们有时间对此作一个全面的总结时,那东西驰骋,紧张繁忙的60多个日日夜夜、风风雨雨仿佛再一次浮现在我们…  相似文献

Abstract

Out of a quickly performed merger between the Left Democrats and the Daisy, a new party has made its appearance in Italy: the Democratic Party (Partito Democratico – PD). In the summer of 2007 three candidates, Walter Veltroni, Rosy Bindi and Enrico Letta campaigned in order to convince sympathizers and supporters of that, yet non-existing party, that they were worthy of the office of Secretary of the PD. The election of Veltroni contributed to the already existing tensions within the centre-left governmental coalition that led to the demise of Prodi's government and to early elections. In April 2008, though receiving 33 per cent of the vote, the Democratic Party suffered a serious defeat. This article explores the reasons of the defeat and analyses its consequences on the restructuring of the Italian party system and the future of the Italian political system. Unless the Democratic Party is capable of finding an adequate organizational model and of expanding its electoral support beyond the areas of the traditional entrenchment of the former Communist party, the centre-right seems destined to guide Italian politics for some time to come.  相似文献

The February 2013 Italian general elections were characterized by the highest volatility to date. Although, thanks to the majority bonus, the Partito Democratico (Democratic Party) obtained the absolute majority of seats in the House of Deputies, it could not be considered the winner of the elections. Lacking a majority in the Senate, it was obliged to form a government with Silvio Berlusconi's party and with the rather small number of parliamentarians elected in former Prime Minister Mario Monti's list. In spite of his last-minute surge, Berlusconi was a clear loser, having lost almost six million votes in respect of his 2008 victory. Comedian Beppe Grillo's Movimento Cinque Stelle (Five Stars Movement) received the highest-ever number of votes for a new entry into any post-war European general election. Unwilling to play the coalitional game and made up of inexperienced and incompetent parliamentarians, Grillo's party has remained isolated and ineffective. The present Italian party system consists of three poles, the Movimento Cinque Stelle playing the role of anti-system party. Institutional reforms and especially reform of the electoral system, which has been struck down by the Constitutional Court, are again the focus of debate. Restructuring of the Italian political system is yet to come.  相似文献
