In recent years there has been growing interest in the discipline of computing in relation to cultural heritage, parallel with developments in greater user participation in archives and advances in documentation work. These trends are reflected in the case of a documentation project of an old Chinese cemetery in Singapore, Bukit Brown Cemetery. This case was characterised by tensions among the ‘wild’ array of emerging individual participants and archivists that took the momentum away from both more formal NGOs and government institutions in documenting, archiving and raising awareness of the heritage of the site when part of it was announced to be set aside for a new highway. The case presents a compelling need for participatory archives, facilitated by computing interventions encouraging public engagement and visits to the site. Being actively involved in the documentation process, the authors reflect on how conceptual frameworks of records may assist in designing new media innovations and informing the ways by which a cemetery may be documented. Through these reflections, the authors argue for the active participation of archivists and records professionals in documentation work, and demonstrate how, in the creation and keeping of records, they shape the collective imagination of the public and other stakeholders in heritage sites.  相似文献

Using China and India as examples, this article analyses how different regimes influence people’s perceptions of environmental rights. In addition to a literature review and fieldwork, it looks at two documentaries reporting environmental movements in rural China and rural India to investigate the politics of expression in their environmental arenas. In order to enrich the understanding of the grassroots movements in the two countries, the study examines how their common people differ from middle-class activists in the way in which they participate and make alliances in civil society. The findings suggest that the Indian campaigners tend to seek allies in civil society in order to formulate a joint voice in the public sphere, while the Chinese campaigners aim to gain assistance directly from official institutions. The poor communication among the public may result in a shortage of critical discourses in support of people’s movements and weaknesses in the legitimacy of public participation in the environmental arena.  相似文献

This paper analyses the publication patterns of researchers in the field of applied sciences at Universities of Technology in South Africa. Aspects investigated include publications in SCOPUS-listed journals; number of citations and countries of publication. Collaborative research patterns at national and international levels were also investigated. A bibliometric analysis approach was followed using SCOPUS as the main source of data and analysing the articles published in selected applied science disciplines. Results show that researchers in the field of applied sciences in universities of technology have increased their number of publications over the past 10?years and are also working in conjunction with other researchers both nationally and internationally. The analysis is an important addition to the field in South Africa which helps in measuring how institutions are positively responding to government incentives in research. The results are also important to information professionals who are increasingly playing an important role in research impact assessments.  相似文献
