Wiederverwendbare Algorithmenschemata in ML am Beispiel von Graphdurchlauf-Problemen

Zusammenfassung. Die Programmierung von Algorithmenschemata durch die Parameterisierung von Programmteilen ist eine M?glichkeit der Wiederverwendung von Software. Dieser Ansatz wird insbesondere von der funktionalen Programmiersprache ML durch eine sehr ausgereifte Modulsprache mit Signaturen, Strukturen und strukturabbildenden Funktoren unterstützt. In diesem Artikel demonstrieren wir, wie man auf diese Weise Parameterisierung und Wiederverwendung realisieren kann. Dabei wird eine Anwendung, n?mlich schematischer Graphdurchlauf mit Vererbung und Synthese als Verallgemeinerung des vom übersetzerbau her bekannten Prinzips, im Detail vorgestellt; einige weitere Anwendungsbereiche werden skizziert. Eingegangen am 21. Februar 1996 / Angenommen am 20. August 1996

‘The feeling of exclusion’: Young peoples' perceptions of art galleries

This article first looks at the relationship between museums and art galleries and their potential audiences and, in particular, the under-represented sector of young visitors. It examines the main findings from the limited research available on young visitors, and goes on to discuss theories delineating the differences between the cultures, identities and values of culture consumers and culture providers. The second part of the article looks at what specific museums have done towards being more inclusive in their appeal, and then reports the findings of a survey of young people in relation to New Zealand's Auckland Art Gallery. The survey found that young people's ideas of what constitutes modern, relevant art do not match standard art criteria, and that most exhibitions and marketing methods do not mesh with their worldview. The article concludes by using data from the survey to suggest ways of engaging more young people with public art galleries.     

Essentialism, adaptation and justice: Towards a new epistemology of museums

This article treats the prevalent confused mixture of utilitarian, art-and-knowledge-for-their-own-sake and ideological interpretations of the purpose of museums as a problem of epistemology, arguing that that key dimensions of museum knowledge (of objects, visitors, museums themselves, and of society) need to be integrated to achieve coherence. A new object-based, visitor-centred, storytelling epistemology is proposed. This would take an interdisciplinary approach and aim to unleash, rather than mute the real power of objects. It would address human destructiveness, as well as celebrating human creativity and the wonders of nature. It would respect the meaning-making practices of real, as opposed to idealized, imaginary visitors, and promote staff self-awareness in managing bureaucratic drift into introversion and avoidance of difficult issues. Incorporating a theory of justice, it would erode boundaries created by presentation traditions which, though marginal to object experiences, discriminate in favour of specific social groups—often groups with whom staff identify. Providing a museum service on a visibly fair basis is essential for museums to achieve intellectual coherence as well as societal support.     

Counterfeit museology

Museums are not usually seen to be agents of change. If they are to serve as important mechanisms for empowering local communities to define, recognize, and develop their own indigenous heritages, they should first consider a potential contradiction contained within this initiative: museums specialize in the representation of other peoples, while people have the sovereign right to represent themselves. Left unresolved, this contradiction could produce counterfeits of good intentions. The introduction of professionalized cultural management may mitigate the responsibilities of the citizenry to actively participate in the production and preservation of their own heritage.     

ISO9000：2000与图书馆质量管理的原则

应用ISO9000：2000的管理理念，对照质量管理标准中的相应条款，分析和阐述图书馆质量管理中应遵循的8项原则：以顾客(用户)为关注焦点；领导作用；全员参与；过程管理；系统管理；持续改进；基于事实的决策和与供方互利。在此基础上，就每项质量管理原则在图书馆中的实际应用提出相应的措施。

The IR Has Two Faces: Positioning Institutional Repositories for Success

This article describes the ongoing efforts at University of Nevada, Las Vegas (UNLV) Libraries to evolve the role of the institutional repository (IR) and to effectively position it within the context of the Libraries’ collections, research support, and scholarly communication services. A major component of this process is re-examining the fundamental aims of the IR and aligning it to the Libraries and the campus strategic goals. The authors situate UNLV Libraries’ experience within the context of the current literature to provide background and reasoning for our decision to pursue two, at times conflicting, aims for the IR: one for scholarly communication and another for research administration.     

Technological research in the EU is less efficient than the world average. EU research policy risks Europeans’ future

We have studied the efficiency of research in the EU by a percentile-based citation approach that analyzes the distribution of country papers among the world papers. Going up in the citation scale, the frequency of papers from efficient countries increases while the frequency from inefficient countries decreases. In the percentile-based approach, this trend, which is uniform at any citation level, is measured by the e_p index that equals the P_{top 1%}/P_{top 10%} ratio. By using the e_p index we demonstrate that EU research on fast-evolving technological topics is less efficient than the world average and that the EU is far from being able to compete with the most advanced countries. The e_p index also shows that the USA is well ahead of the EU in both fast- and slow-evolving technologies, which suggests that the advantage of the USA over the EU in innovation is due to low research efficiency in the EU. In accord with some previous studies, our results show that the European Commission’s ongoing claims about the excellence of EU research are based on a wrong diagnosis. The EU must focus its research policy on the improvement of its inefficient research. Otherwise, the future of Europeans is at risk.
