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

Multilingual modeling of cross-lingual spelling variants     

Krister Lindén 《Information Retrieval》2006,9(3):295-310

Technical term translations are important for cross-lingual information retrieval. In many languages, new technical terms have a common origin rendered with different spelling of the underlying sounds, also known as cross-lingual spelling variants (CLSV). To find the best CLSV in a text database index, we contribute a formulation of the problem in a probabilistic framework, and implement this with an instance of the general edit distance using weighted finite-state transducers. Some training data is required when estimating the costs for the general edit distance. We demonstrate that after some basic training our new multilingual model is robust and requires little or no adaptation for covering additional languages, as the model takes advantage of language independent transliteration patterns. We train the model with medical terms in seven languages and test it with terms from varied domains in six languages. Two test languages are not in the training data. Against a large text database index, we achieve 64–78 % precision at the point of 100% recall. This is a relative improvement of 22% on the simple edit distance.  相似文献

The powerful image and the imagination of power: the ‘new visual turn’ of the CPC’s propaganda strategy since its 18th National Congress in 2012     

Jiang Chang  Hailong Ren 《亚洲交流杂志》2018,28(1):1-19

This paper adopts the academic tool of discourse analysis to examine the ‘new visual turn’ of the Communist Party of China’s propaganda work since the 18th CPC National Congress when Xi Jinping was inaugurated as the leader of Chinese Communists. A thorough review of the new visual means the Party uses for photojournalism, TV news, animated cartoons and online promotional videos points to three developments markedly different from traditional discursive strategies: a full embrace of Confucian ethics, articulation of the Internet-based popular culture and subcultures, and an effort to fortify Xi’s personal authority as a political idol. The paper concludes that the ‘new visual turn’ of CPC propaganda after the 18th Party Congress suggests that the Communist discourse has evolved to a new stage where sophisticated manipulation of sleek technological tools substantiates a rigorous, dynamic CPC discursive system more at ease with itself and more powerful than ever in shaping the mainstream political culture in China.  相似文献   

Spanish historic archives’ use of websites as a management transparency vehicle     

Ana R. Pacios  José Luis La Torre Merino 《Archival Science》2018,18(2):185-205

Against the backdrop of Spain’s Transparency Act, this article discusses the presence or otherwise of a series of document types, proposed as management-related transparency indicators, on 61 (8 national and 53 provincial) historic archive websites. Although examples of good practice were identified, the information provided was found to be scant, in particular as regards lines of action, organisational objectives and yearly reports. The information most commonly provided on the websites included the collection classification chart, service use regulations and citizen charters. The inference drawn was that archives, so intently focused on their role in the application of the Act by the organisations they serve, neglect their own administrative obligations in respect of its provisions. The recommendation is that as government-funded and subsidised public service institutions, historic archives should exercise transparency by furnishing the information stipulated in the Act on their websites.  相似文献   

WhatsApp as a Tool for Participation on Spanish Radio: A Preliminary Study of the Program Las Mañanas on RNE     

Flávia Gomes-Franco e Silva  Juliana Colussi  Paula Melani Rocha 《Journal of Radio & Audio Media》2018,25(1):77-91

This study was conducted in an environment of widespread use of social media and mobile applications in the mass media. The general goal of the study was to analyze the use of WhatsApp in cybermedia, specifically in radio. A case study was proposed to examine the use of WhatsApp on the program Las mañanas de RNE, broadcast by Spanish National Radio. It was found that the public was very accepting of the program’s initiative to solicit WhatsApp voice messages, beginning in November 2015. The case study used audio files of a direct broadcast that included specific times for audience participation. The use of WhatsApp was accepted by the audience, in addition to the use of the conventional telephone, as a tool well-suited to listener participation in radio programming. Finally, the study highlights the importance of interactive, participatory spaces in broadcasts through the creation of synergies with new forms of online participation.  相似文献
