AbstractThis article analyzes the role of national bibliographies—with particular reference to the Italian National Bibliography—as relevant tools for national bibliographic control. In the first part of the article, the historical and scientific context of international standards is summarized. The second part describes the role played by the Central National Library of Florence (BNCF) in the realization of the bibliographic control of Italian publications. The limits and the potential of the Italian National Bibliography produced by BNCF are highlighted and compared with the Italian National Library Service (SBN), which is the most important national collective catalog among Italian libraries. 相似文献

In this paper, we examine how patterns of scientific collaboration contribute to knowledge creation and diffusion. Recent studies have shown that scientists can benefit from their position within collaborative networks by being able to receive more information of better quality in a timely fashion, and by presiding over communication between collaborators. Here we focus on the tendency of scientists to cluster into tightly knit communities, and discuss the implications of this tendency for scientific production. We begin by reviewing a new method for finding communities, and we then assess its benefits in terms of computation time and accuracy. While communities often serve as a taxonomic scheme to map knowledge domains, they also affect the way scientists engage in the creation of new knowledge. By drawing on the longstanding debate on the relative benefits of social cohesion and brokerage, we discuss the conditions that facilitate collaborations among scientists within or across communities. We show that highly cited scientific production occurs within communities, when scientists have cohesive collaborations with others from the same knowledge domain, and across communities, when scientists intermediate among otherwise disconnected collaborators from different knowledge domains. We also discuss the implications of communities for information diffusion, and show how traditional epidemiological approaches need to be refined to take knowledge heterogeneity into account and preserve the system’s ability to promote creative processes of novel recombinations of ideas. 相似文献

意大利新现实主义电影塑造了一系列命运悲惨的儿童形象。作为承载导演思想情感的一种叙事符码,儿童形象在电影中的表现始于童真天性的铺垫,终于残酷环境对他们的扭曲与摧残。对儿童外部世界的关注、内心世界的开掘,体现出新现实主义深沉的悲悯意识。 相似文献

This article analyzes how Catholicism had a central role in the identity-creation process after the War. The study employs the online archive of the national agency ‘Istituto Luce’ to analyze 261 newsreels about religion released between 1946 and 1965. The article uses (i) Benedict Anderson’s work on imagined communities and (ii) Roland Barthes’ concept of mythology as theoretical frameworks. This study indicates that the majority of newsreels presented Catholicism as intertwined with Italian politics, and as a central element of both tradition and modernity. These findings suggest that the newly formed Italian democracy used the media to emphasize certain aspects of Catholicism, while overlooking others, such as its implications with the Fascist regime. In this way, the media contributed to create a post-war myth where Catholicism represented a moral resource for the country’s leaders and citizens. This historical process contributes to explain the contemporary pervasiveness of Catholicism in Italian media. 相似文献

By analyzing all of the keywords and hashtags that became Trending Topics (TTs) in the Italian Twittersphere during both an electoral period and a non-electoral period, we evaluated what Italian Twitter users discussed. We found that topics about actors and issues in the entertainment field (e.g., singers, Hollywood stars and television stars) drive Italian discussions and that the political sphere is a secondary topic that elicits minor arguments within users’ conversations. However, we believe that even this low level of discussion about politics was able to influence the public agenda, thanks to the advent of a hybrid media system in Italy. In fact, Italian print media and television constantly covered the individual tweets or hashtags of a niche of citizens who were discussing politics on Twitter. Television, a part of the Italian media system that is highly consumed by the public, is also a primary factor in determining the appearance of a specific actor or issue on the TT list. Furthermore, we empirically confirmed the logic of breaking news events on Twitter, a microblogging site that primarily focuses on exceptional occurrences. 相似文献

The multi-user virtual environment Second Life has drawn attention from many librarians who established virtual libraries and information spaces there. Even as interest in Second Life diminishes, it is worthwhile to look at how libraries in Second Life were established and what models they followed. This study examines the purposes, users, collections, and community integration of Second Life libraries. Researchers identified over 75 libraries in Second Life through the professional literature and search results within Second Life. Using this sample, they identified seven general categories of libraries and discuss examples of each. Some Second Life library spaces help to set a scene and contribute to the ethos of a larger space. Other Second Life libraries connect physical libraries with virtual communities. Still others serve communities that exist only in virtual spaces, supporting common interests or role-playing scenarios. Finally, some Second Life libraries expand understandings of what a virtual library might be, whether through imaginative architecture or unusual collections. Second Life libraries offer collections of resources tailored to the needs of individual communities and make them available in different formats. They also offer social and educational programs, much as physical libraries do. Whatever the future of Second Life, the libraries that have been established there raise important questions for future virtual library work. 相似文献

The article contributes to the research on media management by approaching the audience as consisting of communities, instead of considering it a mass audience. By developing audience community as a concept in media management and audience research and investigating mainstream newspapers’ perceptions and practices of audience community relations, the study aims to provide a future outlook for the changing community nature of audiences. Newspaper organizations are starting to perceive the audience as a more concrete network of people, and journalistic processes can increasingly consist of generating platforms and practices for communication and communal activities with and among the audience. In the article, these processes are studied empirically by means of a qualitative study carried out in Finnish, Japanese, and Korean newspapers. Interestingly, the findings indicate that audience communities do not, after all, play an important role in the daily practices of the newspapers. The engagement with audience communities in social media is only occasional, intermittent, and by no means systematic. By contrast, interaction with offline communities seems to be more familiar and considered more valuable than connecting with audience communities in social media. 相似文献

The emergence and the widespread adoption of the Internet have brought about many dramatic changes on different levels. Due to its inherent characteristics, the Internet has become an engine of political mobilization and participation, and has led to the proliferation of online communities. Few studies examine how political groups use the Internet to build communities and forge alliances in cyberspace, and this study attempts to bridge this gap. Registered political parties and political expression groups in Singapore were selected for this study. Through hyperlink analysis, the study shows that reciprocity and similarity, two main characteristics observed in online communities, were found in the groupings formed by these political groups. Interestingly, most of the online affiliations that exist among these groups reflect those offline. 相似文献

This paper presents a three-level conceptual and methodological framework for assessing local journalism and the extent to which it meets community information needs. This research grows from frequent calls from policymakers, foundations, and advocacy groups for methods and measures to facilitate comparative analyses of the state of local journalism in different communities. Further, the goal here is to develop a methodological approach that can be realistically scaled to large numbers of communities in order to facilitate analysis of both the factors that affect the state of local journalism and the ways local journalism may affect the state of local communities. The methodological approach presented here focuses on infrastructure (the availability of journalistic sources), output (the quantity of journalistic output from these sources), and performance (the extent to which this output is original, is about the local community, and addresses critical information needs). An exploratory application of this methodological approach is then presented for three communities. The results indicate substantial differences in the journalism infrastructure, output, and performance across these communities and suggest possible points of focus for future research. 相似文献

This article will discuss propaganda in the press used by the Italian fascist regime to create and disseminate a negative image of France and socialism. The ‘Paris, 1937’ exhibition represented a pretext for the Italian press to attack the Popular Front on both policy and competence. Manipulating information, the propaganda fabricated an idea of ‘otherness’, presenting France as the chaotic antithesis to the orderly Italian regime. France was presented as a country full of drunks and idlers, as a nation descending into chaos due to the social economic reforms of the Blum government; images that were juxtaposed with a state thriving under fascist corporatism. With the use of archive files and press-clippings, this work intends to illustrate the construction of stereotypes to feed the fear of socialism in Italy by the fascist press. 相似文献

Contemporary standards suggest that information literate activity is a solitary process. As a corrective, research and pedagogical theories related to “learning communities” and “communities of practice” have become valuable sites of inquiry for librarians. The author provides strategies for making community a topic of instruction. 相似文献
