Verteilte Metadatenverwaltung und Anfragebearbeitung für Internet-Datenquellen     

Markus Keidl  Alfons Kemper  Donald Kossmann und Alexander Kreutz 《Informatik - Forschung und Entwicklung》2002,17(3):123-134

Zusammenfassung.   Wir pr?sentieren in dieser Arbeit das ObjectGlobe-System, ein offenes und verteiltes Anfragebearbeitungssystem auf Internet-Datenquellen. ObjectGlobe erweitert die begrenzten F?higkeiten des Internets bezüglich Anfragebearbeitung, indem es einen offenen Marktplatz schafft, in dem eine Vielzahl von Anbietern Rechenzeit, Daten und Anfrageoperatoren bereitstellen. Den Schwerpunkt dieses Beitrags bildet die im Rahmen des ObjectGlobe-Projekts entwickelte Metadatenverwaltung MDV, ein verteiltes Metadaten-Management-System. Es besitzt eine 3-schichtige Architektur und unterstützt Caching und Replikation in der Mittelschicht, so dass Anfragen lokal ausgewertet werden k?nnen. Benutzer spezifizieren die Informationen, die sie ben?tigen und die repliziert werden, mit Hilfe einer besonderen Regelsprache. Um Replikate aktuell zu halten und die Replikation von neuen und relevanten Informationen anzusto?en, verwendet das MDV-System einen neuartigen Publish & Subscribe-Algorithmus. Wir beschreiben diesen Algorithmus im Detail und zeigen, wie er mit Hilfe eines normalen relationalen Datenbanksystems implementiert werden kann. Eingegangen am 19. November 2001 / Angenommen am 30.

Questioning the pace and pathway of e-government development in Africa: A case study of South Africa's Cape Gateway project     

Blessing Mukabeta Maumbe  Vesper Owei  Helen Alexander 《Government Information Quarterly》2008

The paper examines e-government development in Africa. This study is based on the Cape Gateway project in South Africa, a leading e-government initiative on the continent. We observe that African countries have jumped on the e-government band wagon by looking mostly at the benefits without a clear risk assessment. We argue that African countries should question the pace and pathway for their e-government programs. We caution that e-government models from developed countries do not necessarily work in Africa. E-government programs in Africa should be balanced with the provision of basic needs and infrastructure. We conclude that e-government in South Africa should adopt multi-cultural approaches, and must be underpinned by national development priorities. We recommend that the Cape Gateway must address the socio-economic context and needs of the country. The pace and pathway of its e-government must depend on the availability of both financial and human resources and also user satisfaction.  相似文献   

Excluding archival silences: Oral history and historical absence     

Ben Alexander 《Archival Science》2005,5(2-4):1-11

Despite our society's increasing reliance on electronic documentation, to-date archives remain, largely, material repositories of cultural memory. It is an accepted historical problematic, however, that culture is often resistant to material preservation. There exists an undeniable and profound tension between scholarly efforts to reconstruct history and interpret cultural traditions and the fragmentary, and often limited, material record. That is to say, scholarship is shaped by a sinuous negotiation around the historical silences that encompass all of material culture. Historical silences, however, can at times be marginalized (or at best excluded) by a sensitive configuration of material evidence with oral history.Excluding Archival Silences: Oral History and Historical Absence uses a historically and geographically specific example of oral history to engage in a more generalist discussion of how oral reflection, especially when shaped by material evidences, can be an especially effective tool for preserving the dynamics of culture that often remain undocumented.  相似文献

The secrets of failing better: Accessible publishing at SAGE. A case study          下载免费PDF全文

Caroline Manis  Huw Alexander 《Learned Publishing》2018,31(1):63-68

Key points

• Accessibility is often misunderstood as a concept that is niche or of secondary importance.
• Reframing accessibility as improving the overall user experience instantly changes the perspective; accessibility becomes a critical requirement worthy of investment and resources.
• The single most prevalent complaint amongst librarians is the time it takes to get hold of accessible content.
• An accessibility roadmap provides structure and transparency for digital accessibility projects within the organization.
• Publishers' non‐compliance with accessibility standards will increase their risk of sales declines and legal complications over time.
• The SAGE A.C.C.E.S.S.I.B.L.E mnemonic offers suggestions on how to devise a successful accessible publishing programme.

Shared Entertainment,Shared Opinions: The Influence of Social TV Comments on the Evaluation of Talent Shows     

Stephan Winter  Nicole C. Krämer  Brenda Benninghoff  Christine Gallus 《广播与电子媒介杂志》2018,62(1):21-37

The present research investigated whether co-viewer comments in social TV interactions are able to enhance or weaken media effects. With the example of talent shows, the valence of co-viewer comments (pro/contra/none) as well as the type of content (antisocial behavior vs. conventional performance) were varied in an experiment (N = 117). Results showed that participants’ own comments and their private attitudes about the judges varied in line with comment valence. Findings suggest that social TV viewers are prone to social influence of their co-viewers, which might amplify problems regarding the portrayal of antisocial behavior in reality TV.  相似文献   

Carrying Forward the Uses and Grats 2.0 Agenda: An Affordance-Driven Measure of Social Media Uses and Gratifications     

Chamil Rathnayake  Jenifer Sunrise Winter 《广播与电子媒介杂志》2018,62(3):371-389

The notion of social media affordances has not been fully integrated into the uses and gratifications literature. Building on the MAIN (modality, agency, interactivity, and navigability) model, this study develops and tests a social media uses and gratifications scale with a sample of 393 college students. Results of the study support the MAIN model, as conceptualizing social media uses and gratifications as a second-order factor structure with 4 different types of affordances displays similar goodness-of-fit to a single-order factor structure. A confirmatory factor analysis with a second sample of 313 adults further confirms the applicability of the scale among the general population.  相似文献
