The study explores the characteristics of China's independent research articles published from 1980 to 2011, based on the database of Science Citation Index Expanded. The publication outputs of seven major industrialized countries including Canada, France, Japan, Germany, Italy, the UK, and the USA were compared with China. Annual production, field performance, research emphases and trends, top articles, as well as main institutional and individual contributors by its top cited articles were analyzed. Some newly developed indicators related to words in title, author keywords, KeyWords Plus, first author, corresponding author, and Y-index were employed to provide in-depth information on topic and author contributions. Results showed that China has been closing the gap with the USA with the greatest growth, and has stood the second since 2006. Most top cited articles were published in 2000s, made up approximately seven tenths of total articles. Pronounced activities were found in chemistry and physics related categories. The core categories included multidisciplinary chemistry, physical chemistry, multidisciplinary materials science, and applied physics. Moreover, China's performance of nanotechnology and science, especially carbon nanotubes, nanoparticles, nanowires, and nanostructures showed dramatic growth. Six top articles with at least 1000 citations were examined, and were observed to concern medicine, nanotube, and adsorption. In addition, main contributing institutions and authors were also revealed and evaluated. Chinese Academy of Sciences played a dominant role, and Tsinghua University, Peking University and five universities in Hong Kong showed good scientific performance.  相似文献

The Internet of things (IoT) is the network of objects/things that contain electronics, software, sensors, and actuators, which allows these things to connect, interact, and exchange data. The users, sensors, and networks generate huge amounts of data from which governments can develop applications and gain knowledge using Artificial Intelligence (AI) techniques. Thus, IoT and AI can enable the development of valuable services for citizens, businesses, and public agencies, in multiple domains, such as transportation, energy, healthcare, education, and public safety. This guest editorial for the special issue on IoT and AI for Smart Government, identifies the challenges involved in implementing and adopting these technologies in the public sector, and proposes a comprehensive research framework, which includes both IoT and AI elements for smart government transformation. Subsequently, the editorial provides a brief introduction of the six papers in this special issue. Finally, an agenda for future research on IoT and AI for smart government is presented, based on the proposed framework and gaps in existing literature, supported by the papers that were submitted to this special issue. The agenda comprises four directions i.e., conducting domain-specific studies, going beyond adoption studies to examine implementation and evaluation of these technologies, focusing on specific challenges and thus quick wins, and expanding the existing set of research methods and theoretical foundations used.  相似文献

This essay compares archival accumulation in clerical and secular principalities in seventeenth-century northwestern Germany. As this is known to be the age of confessionalization, the focus is on confessional convergences and divergences in the development of confession, rule, states, and archives. The sources show the emergence of administration, the accumulation of legitimation and evidence via archives, and confessional competition, as well as coincidences of centralization and separation. Catholic and clerical archives were oriented toward persisting written records and historical traditions, while in Protestant and secular contexts, we find novel developments: a new age, new confessions, the need for a new history together with the creation of a new (historical) identity, and thus, new archives. Later success stories that characterized the Protestant secular state as orderly, administration- and rule-related, and possessing well-indexed archives, however, neglect most Catholic and nongovernmental archives and their qualities.  相似文献

The reading of literature fulfils a vital role in any educated and civilised nation. The book is being transformed, as digitisation becomes an increasing reality, however, literature will continue to retain a key place as a critical social and cultural artefact. Story, in whatever form, will continue to provide experiences of joy, amusement, fear, hope, betrayal, curiosity, love, forgiveness and sadness. Literature can do so much more than simply moving and entertaining us. It can impart knowledge, stimulate the imagination and can teach us about language, our world and our relationship to it. It can help us to relate to and understand one another, and can act both as a mortar to build rich personal and textual histories, and a bridge between our lives and the lives of others. As well, literature can enrich our lives, helping us to encounter ‘other worlds’, languages and experiences that are not within our lived experience. Finally, literature can transform us as language users, learners and people and present us with a different view of the world and our place in it. But as digitisation and new forms of communication change, will how we read and how we access and share books with one another also change? Finally, how might we sustain libraries and other spaces that readers frequent as ‘real’ communities where lovers of books dwell?  相似文献

ABSTRACT

The Russian Revolution Centennial has called forth many exhibitions of the vast holdings of libraries, archives, museums and other collections. This special issue reviews major exhibitions, the history of the collections and the conceptions and strategies of curators. Revolution’s centennial in 2017 called forth numerous conferences, programs, lectures, publications, and other events. One of the richest avenues of celebration and scholarship was the many brilliant exhibitions organized by archives, museums, and other repositories. The centennial provided an occasion for assessing and for rethinking the modes of presentation and the significance of many types of collections. What to show, how to show it, and for whom became big questions to which curators, archivists, art historians, and many others came up with big answers. These exhibitions and initiatives have pointed the way toward new and welcome collaboration between curators, archivists, historians of art and photography, and political and social historians of the Russian Revolution.  相似文献

Compared with journal articles, books can provide broader, deeper and more comprehensive information, and often have higher expertise and academic depth. However, most researches on book assessment focus on measuring academic value of books (e.g. citations analysis) or identifying attitudes of readers (e.g. book review mining), depth and breadth reflected by book contents is neglected. Therefore, in this paper, we measure books’ depth and breadth by mining books’ tables of contents, so as to enrich resources and methods for book assessment research, help users understand book contents quickly and improve efficiency of book selection. Specifically, we measured books’ depth and breadth based on books’ tables of contents via two levels: topic level and feature level. Firstly, we obtained topic-level metrics by identifying topics expressed in tables of contents and calculating topic distributions. Then, we got feature-level results via feature extraction and feature distribution calculation. Finally, we compared depth and breadth metrics and other book assessment metrics. Experimental results reveal that, books’ depth and breadth at two levels are different, and substantial differences between disciplines and book types are obvious. In addition, books’ depth and breadth can provide alternative and supplementary information for assessing multi-dimensional values of books.  相似文献

The information practices of collaborative interdisciplinary researchers, especially in distributed environments, remain understudied. Embracing the naturalistic paradigm, this qualitative case study relies upon semi-structured interviews, snowball sampling, and grounded analysis. Based on interviews with 53 participants from 11 Digging Into Data 3 (DID3, 2014-2016) projects, this study examines the working practices of scholars (library and information science professionals, humanists, and computer scientists) engaging in collaborative, international, data-intensive, publicly-funded interdisciplinary research. Benefits of such work include avoiding redundancy, exploding disciplinary silos, and more ambitious, larger-scale outputs. Challenges and lessons learned center on innovation, flexibility, and failure, translation, intermediaries, divisions of labor and delegation of responsibilities and tasks, conflict resolution, technology, outputs and publication, and timeframe, sustainability, and infrastructure.  相似文献

Special libraries, as differentiated from general public libraries and academic libraries, are devoted to specialized fields of science and technology, agriculture, medicine, social sciences, economics and the like. Such libraries are attached to research organizations, government departments, departments in universities, industrial organizations, professional societies and trade associations, etc. Special libraries customarily maintain a regular and systematic information service covering the immediate and future interests of the organizations of which they are part. This necessitates the development and management of an adequate collection of books, periodicals, reports, patents, standards, government publications, maps, audio-visual records, etc. issuing from a multitude of publishing bodies. In house publications, market surveys, data files, etc. are also brought together in these collections. All items are of course made available for consultation by being adequately classified or indexed and organised in a particular fashion and maintained for future reference.  相似文献
