Color characterization of roofing slates from the Iberian Peninsula for restoration purposes     

Beatriz Prieto  Perla Ferrer  Patricia Sanmartín  Victor Cárdenes  Benita Silva 《Journal of Cultural Heritage》2011,12(4):420

Substitution of slate roofing tiles is a conventional operation during building restoration, since tiles are very difficult to restore or clean because of the high degree of alteration they suffer. Criteria for replacement of historical building stones must be based on geological, geotechnical and esthetic parameters, among which color is of great importance. In this sense, this paper constitutes a comprehensive and useful colorimetric study of roofing slates from the Iberian Peninsula, for the purposes of restoration. The color of 50 commercial varieties of roofing slate mined in quarries from the 12 mining districts in the Iberian Peninsula was analyzed with a spectrophotometer device, by considering the CIELAB color space. The results of the study were used to develop a protocol for characterizing the color of roofing slate and to define the color range of roofing slate from the Iberian Peninsula. In addition, the similarities and differences in the color and microstructure of the different commercial varieties of Iberian roofing slate were established and the limit of acceptability of replacement of one type of slate by another was determined. Parameter h_ab was found to be the most important CIELAB color coordinate as regards the formation of homogeneous color groups, and the specular component excluded (SCE) mode was most sensitive as regards detecting color differences between two samples.  相似文献

Acoustic sounding of the atmosphere     

Victor D Hopper 《Endeavour》1978,2(3):121-126

Measurement of vertical and horizontal wind velocity is of great importance in many contexts, such as investigation of air pollution, weather forecasting, and air-traffic control. In recent years continuously recording acoustic sounders have been developed which give reliable results at reasonable cost: some 200 are now in use in at least 15 countries.  相似文献   

The relationship between the school as a learning organisation and staff outcomes: A case study of Wales     

Marco Kools  Pierre Gouëdard  Bert George  Bram Steijn  Victor Bekkers  Louise Stoll 《European Journal of Education》2019,54(3):426-442

Does the school as a learning organisation affect staff outcomes? This article examines the relationship between the school as a learning organisation and staff job satisfaction and the school's responsiveness to staff needs using a purposefully designed “Schools as Learning Organisations Survey” completed as part of an OECD study in Wales. A positive and significant relationship is found between the school as a learning organisation and both job satisfaction of staff—that is school leaders, teachers and teaching support staff—and the school's responsiveness to staff needs. The article proposes ways of realising these outcomes and identifies areas for further research. Policy makers, school staff and other stakeholders in education and other public sectors internationally can use these findings as supporting evidence in recommending people to develop their organisations into learning organisations, given the potential benefits for employees and the organisation at large.  相似文献   

Analytic Frameworks for Assessing Dialogic Argumentation in Online Learning Environments   总被引：1，自引：2，他引：1  

Douglas B. Clark  Victor Sampson  Armin Weinberger  Gijsbert Erkens 《Educational Psychology Review》2007,19(3):343-374

Over the last decade, researchers have developed sophisticated online learning environments to support students engaging in dialogic argumentation. This review examines five categories of analytic frameworks for measuring participant interactions within these environments focusing on (1) formal argumentation structure, (2) conceptual quality, (3) nature and function of contributions within the dialogue, (4) epistemic nature of reasoning, and (5) argumentation sequences and interaction patterns. Ultimately, the review underscores the diversity of theoretical perspectives represented within this research, the nature of dialogic interaction within these environments, the importance of clearly specifying theoretical and environmental commitments throughout the process of developing or adopting an analytic framework, and the role of analytic frameworks in the future development of online learning environments for argumentation.

Science education — I: The spirit of science     

Victor L. Pollak 《Journal of Science Education and Technology》1993,2(4):513-519

In these two essays we explore the questions: what are the essential features of a workable context for science education? What are the givens, the “of courses,” the “fundamental dispositions” toward science and toward education necessary — or at least sufficient — to provide a fertile ground upon which a functional approach to science education can be established? In the present essay it is argued first that science education must reflect that science is a way of thinking — in fact, more comprehensively, a way of being; and second, and that the fundamentally antiauthoritarian spirit of science must be reconciled with education, with its built-in tendency to be authoritarian.  相似文献
