The Future of English     

Chris Davies 《English in Education》1991,25(3):28-31

The unity of "unitary" English, subsuming "language" and "literature", has always been a central tenet of NATE thinking and a basic assumption of most progressive practice, and is now enshrined in the National Curriculum¹. In this article, however, Chris Davies makes the scandalous proposal that the time has come when "language" and "literature", radically transformed, would be better separated.  相似文献

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.

Do physical activity beliefs differ by age and gender?   总被引：1，自引：0，他引：1  

Rhodes RE  Blanchard CM  Blacklock RE 《运动与训练心理学杂志》2008,30(3):412-423

Age and gender are consistently related to physical activity (PA), yet theoretical explanation for these associations is scant. The present study compared the mean values and correlations of a population sample, divided by gender and age group, with respect to theory of planned behavior beliefs (behavioral, normative, and control) and PA. Participants were a sample (N=6,739) of adults (M age=49.65, SD=16.04) who completed measures of social and health demographics, theory of planned behavior beliefs, and self-reported PA. Mean analyses identified greater perceived control over PA for seniors than for young and middle-aged adults (N>.025). Belief-behavior correlations, however, were not different across age and gender in 24 of 26 tests (q<.19). Thus, PA beliefs are invariant across age and gender with the exception of mean levels of perceived control, which are lower among younger adults than older adults. Factors such as early parenthood and career demands were considered the likely reasons for differences. Overall, the evidence suggests that adapting theoretical models for specific age groups or based on gender may not be necessary.  相似文献   

Biodiversity for Beginners     

Chris Du Feu 《Teaching Statistics》2006,28(3):66-70

Biodiversity is a difficult concept. It can be introduced to young children successfully, laying the foundations for further study in later years. This article describes one practical activity for 5‐ and 6‐year‐old children.  相似文献

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   

Creating Better Learners Through Learning Science: A Sample of Methods     

Chris Brown 《图书馆管理杂志》2018,58(4):375-381

This article proposes the incorporation of learning science into the programming and operation of public libraries. Learning science, a multidisciplinary field spanning cognitive science, psychology, neuroscience, economics, anthropology, and linguistics, has identified proven methods for enhancing learning at any age. The article highlights some of the tools and insights that are most relevant to libraries in their role as centers for informal learning.  相似文献
