The chemical composition of 11 glass panes originating from two 13th century non-figurative windows were analyzed by means of Scanning Electron Microscopy–Energy Dispersive X-ray system (SEM-EDX). The windows were discovered in the back-wall of the triforium during the restoration of the choir of the cathedral St. Michael and St. Gudule in Brussels (Belgium). In order to determine if these windows were fabricated with glass of different origin or not, the compositional difference between the panes were compared with the variation in composition as a result of the following causes: (1) compositional fluctuation between panes cut from the same sheet of glass, (2) compositional fluctuation caused when panes are cut from different sheets that were made with the same batch, (3) compositional fluctuation caused when the glass is made from different batches at the same production center, and (4) compositional fluctuation as a result of glass produced at different fabrication centers. 相似文献

The effects of writing style upon mature older readers’ reading comprehension are considered. Two narrative historical selections, the first emotive and abstract and the second nonemotive and concrete, were employed. Miscue analysis was used to evaluate the efficiency with which each reader used reading strategies across the five systems that cue meaningful comprehension. Miscues were analyzed at the word, clause, sentence, and intersentence levels. In addition, interview schedules were employed to identify readers’ perceptions of preferred reading strategies and to permit a comparison with actual performance. The findings indicate that mature older readers are consistent in cue system utilization. A preference for the word cue system influenced both the use of cues from other systems and comprehension. Use of the word‐level cue system is inversely related to the use of the other available cue systems. Preference for cues within words also appears to be inversely related to comprehending effectiveness. The subjects’ perceptions of the reading process and their actual reading performance appeared to determine patterns of cue system use more clearly than did the differences in materials. As a result, those developing materials intended for use in programs with older persons should not only be concerned with the content and quality of those materials but also the skills and perceptions of those who will use the materials. 相似文献

ABSTRACT An orthopedagogical method for teaching children with a depression is presented here. Relatively unknown in the English‐speaking world, orthopedagogy is a pedagogical discipline that is aimed at an entire action field. It does not target the child with handicap, but the entire problematic educational situation (PES). Orthopedagogy is the scientific study of assistance given to those concerned with a PES ‐ namely, the child, parents, brothers and sisters, grandparents, and so on. To break through a PES or to get rid of it, the orthopedagogician has to listen to the orthopedagogical request for help of the child and give an appropriate answer to it. On the basis of a theoretical model of Paul Gilbert, an orthopedagogic request for helping children with a depression was formulated. Gilbert's model offers a perspective derived from evolution theory and argues for the adoption of a bio‐psychological approach. Children with a depression request a warm and loving climate, an attractive and simple education situation and close involvement on the part of the educator. To answer that request, we set orthopedagogical action on two tracks. On track 1 (dialogical action) we try to break through the PES by asking the educator to over‐accentuate the pedagogical climate, the education situation and his/her own presentation. On track 2 (technical action) we designed an approach aimed at children aged between 6 and 12 years with a depression. 相似文献

In this paper we present a new methodology for detecting differential item functioning (DIF). We introduce a DIF model, called the random item mixture (RIM), that is based on a Rasch model with random item difficulties (besides the common random person abilities). In addition, a mixture model is assumed for the item difficulties such that the items may belong to one of two classes: a DIF or a non-DIF class. The crucial difference between the DIF class and the non-DIF class is that the item difficulties in the DIF class may differ according to the observed person groups while they are equal across the person groups for the items from the non-DIF class. Statistical inference for the RIM is carried out in a Bayesian framework. The performance of the RIM is evaluated using a simulation study in which it is compared with traditional procedures, like the likelihood ratio test, the Mantel-Haenszel procedure and the standardized p -DIF procedure. In this comparison, the RIM performs better than the other methods. Finally, the usefulness of the model is also demonstrated on a real life data set. 相似文献

This study analyzes publishing patterns of the staff of the University of Ibadan College of Medicine, Nigeria, based on a bibliography prepared by the authors. Data-gathering for the bibliography is described. An analysis is made of journals staff published in for the period 1961-1980, focusing on changes in journal order rank, publishing locations, and subject spread. A ranked list of the leading journals for the period 1976-1980 is given, showing the importance of local publishing and pointing to the need for local indexing. 相似文献

Conclusions We are living a deep change in the information transfer process involving the different actors of the editorial scene (from
authors to editors, web-editors, e-publishers and readers), who occasionally play different roles at the same time (e.g.,
authors sometimes bypass the editor thus assuming direct responsibilities in the diffusion of documents in the Internet).
Furthermore, information producers, managers or seekers often show twofold personalities like Dr. Jekyll and Mr. Hyde. They
would like to find all documents free on the Internet and be able to read original, reliable, and high quality information,
but they are sometimes reluctant to spread their papers through online nonofficial channels as they care for the impact factor,
prestige, and career advancement.
It is a revolutionary period in which new and alternative forms of scholarly communication live together with more traditional
ones and the future is difficult to define. Recent initiatives of open access—such as Pubmed Central, Public Library of Science,
Budapest Open Access Initiative—are contributing to define new trends in the editorial market, challenging the traditional
distribution channels, mainly managed by commercial editors, and placing the authors’ role and publication copyrights under
severe discussion.
In this landscape, GL now has new dignity and becomes closer and closer to innovative scientific publications supported by
researchers in view of a generalised movement towards open access. The nuances of grey are becoming lighter and lighter. The
questions are many, the answers few, but, in any case, the ethical responsibility of producing and issuing quality documents
can never be disregarded. 相似文献

Three MEDLINE Internet interfaces are compared: PubMed, Internet Grateful Med, and Ovid MEDLINE. Although these interfaces all search MEDLINE, significant differences exist in terms of their search interfaces, presentation of results, and special features. This paper examines these variations and explores some of the advantages and disadvantages of the three interfaces. 相似文献

Several studies concluded that deep reflection is infrequently reached in student portfolios. An explanation for these disappointing conclusions might be that motivation for portfolio reflection determines the quality of reflection. This study aimed to examine the relationship between motivation for using digital portfolios and reflection. Participants were 156 eleventh-grade students in secondary education, whose motivation for composing a digital portfolio was measured by the motivation part of the Motivated Strategies for Learning Questionnaire. Portfolios of 37 of the 156 students were examined in terms of the amount and nature of reflection by means of a coding scheme based on Mezirow's model of transformative learning. On average, one-fifth (19.5%) of the paragraphs in a portfolio contained reflection, and paragraphs with deep reflection were hardly found (0.8%). It was concluded that motivation for composing a portfolio was fair, but not related to the amount and nature of reflection. This exploratory study gives rise to further research into factors that might influence the quality of portfolio reflection. 相似文献
