美国凯恩斯主义与美国宏观调控     

任钢建  李英 《贵阳金筑大学学报》2001,(3)

标志着现代西方经济学开始的凯恩斯经济学,自19世纪30年代产生后很快传入美国,并在美国演变和发展成一种新的经济理论——美国凯恩斯主义。美国凯恩斯主义政策的核心是主张国家干预经济,对经济运行实行宏观调控。宏观调控使得美国经济长期持续增长,出现“两高”和“两低”的经济现象,为世界其他国家经济活动提供了一定的参考作用。  相似文献

基于无监督图神经网络的学术文献表示学习研究     

丁恒  任卫强  曹高辉 《情报学报》2022,41(1):62-72

学术文献特征表示,是学术文献搜索、分类组织、个性化推荐等学术大数据服务的关键步骤。研究表明,图神经网络能够有效学习文献的特征表示,然而当前研究主要集中在有监督学习方法上,不仅对数据集的大小和质量的要求较高,且学习到的文献特征表示与具体任务高度耦合。基于此,本文将四种无监督图神经网络方法引入学术文献表示学习,从Cora、CiteSeer和DBLP (database systems and logic programming)数据集的引文网络、共被引网络和文献耦合网络中学习文献的表示向量,并应用于文献分类和论文推荐两大下游任务。研究结果表明,(1)深度互信息图神经网络适合于文献分类任务,对抗正则化变分图自编码器则在论文推荐任务上性能更佳;(2)Cora数据集上的结果表明,相较于共被引和文献耦合网络,引文网络更适合于学习通用的文献表示向量。  相似文献

英国公共服务广播面临的问题及对策     

侯红霞 《中国广播电视学刊》2008,(4):91-92

公共服务广播(Public Service Broadcasting,在本文中主要指电视广播)在英国的历史由来已久,公营的立法体制保证了节目较为丰厚的资金来源,也催生了高品质的节目内容.英国公共广播电视机构出品的节目通常是由本国制作的原创性作品,内容精良,创意新颖,很少是来自国外的舶来品.为了保证公共广播电视节目的公众服务性,英国广播电视和通信的最高管理机构--通信办公室(the Office of Communications,Ofcom)还会定期对公共广播电视机构进行评估,考察它们是否达到了公共服务广播的目标,并对之如何保持和加强公共广播的高品质服务提出建议.  相似文献   

Controlling the field of academic economics in Hungary, 1953–1976     

György Péteri 《Minerva》1996,34(4):367-380

Conclusions On the basis of these findings, I suggest that the structure and organisation of the field of Hungarian economics under state socialism should be described as a case of partitioned bureaucracy.⁹ The compromise between research economists and the political elite in the New Course era between 1953 and 1955¹⁰ survived the post-1956 reaction in so far as political economy, with its predominantly legitimatory and ideological functions, remained partitioned from the other sectors in the field through the remainder of the state-socialist period. This secured considerable protection both for Marxist-Leninist political economy—which faced the destabilising effects of exposure to the findings of serious empirical research—and for the other sectors, which were professionally oriented and earnestly interested in the pursuit of unbiased empirical research, free from stifling agitprop interference. Our data concerning the reputational control of the field reflects only one, although very important, aspect of this partitioning. Another and much plainer aspect is that, from the early 1960s, the Agitation and Propaganda Department of the Central Committee no longer exercised control over the field, except in the political economy sector.The proposition about the mechanism paradigm should not be taken seriously as a statement of a Kuhnian type of intellectual organisation of Hungarian economics, with reform economics at its hard theoretical core. But it should certainly be taken seriously as a reflection of the sociopolitical structure which emerged and developed from the mid-1950s onwards. Neither the politicians nor the economists saw as necessary or even contemplated the integration of Hungarian economic research with Western mainstream economic thought. In exchange for the professional expertise and socio-economic intelligence necessary for the exercise of power, Hungary's state-socialist political class offered their economists relative autonomy and freedom from interference. The price the economists had to pay was partly to refrain from openly and systematically challenging the beliefs perpetuated by the political economy of socialism, and partly to accept in their research the paramountcy of policy orientation. But this burden they assumed willingly since it made them the only group within Hungary's academic intelligentsia—indeed, the only group in Hungarian society outside the political class—with the privilege of being coopted to the institutions with power over some restricted domains of policymaking. After 1989, especially under the conservative Antall government, this proved less than advantageous.¹¹ Although the benevolence of many critics is open to question, it could greatly benefit the field if the economists' expulsion from contemporary politics went hand in hand with provision of the material, intellectual and institutional conditions for a new approach where a fundamentally scientific orientation is paramount.  相似文献
