Quantifying and visualizing change: Strain monitoring of tapestries with digital image correlation     

Frances Lennard  Janice M. Dulieu-Barton 《文物保护研究》2014,59(4):241-255

A three-year research project at the University of Southampton (2007–2010) investigated whether monitoring techniques commonly used by engineers to assess the strength and durability of materials could be usefully applied to inform the condition assessment of historic tapestries. To date it has not been possible to obtain an objective picture of the overall condition of a tapestry; the study investigated whether it is possible to identify precursors of structural damage. The two techniques, digital image correlation (DIC) and optical fibre sensors, were used to monitor a representative wool fabric, specially woven tapestry samples, a newly woven tapestry, and historic tapestries, both in the laboratory and in situ in a historic house. This study first sets out to answer the question: can DIC be used to monitor and visualize strain in historic tapestries? It is shown that DIC can be used successfully. Secondly, it discusses the map function, a novel development which allowed the monitoring equipment to be moved, so that it could be used in situ in a historic house. Thirdly, it provides further details of the experimental work using optical fibre sensors to confirm the accuracy of the DIC technique.  相似文献   

Aerobic exercise did not have compensatory effects on physical activity levels in type 2 diabetes patients

Although exercise promotes beneficial effects in diabetic patients, some studies have questioned the degree of their importance in terms of the increase in total energy expenditure. In these studies, the decrease of physical activity levels (PAL) was referred as “compensatory effect of exercise”. However, our aim was to investigate whether aerobic exercise has compensatory effects on PAL in type 2 diabetes patients. Eight volunteers (51.1 ± 8.2 years) were enrolled in a supervised exercise programme for 8 weeks (3 d · wk^?1, 50–60% of VO₂ peak for 30–60 min). PAL was measured using tri-axial accelerometers in the 1st, 8th and 12th weeks. Biochemical tests, cardiorespiratory fitness, anthropometric assessment and body composition were measured in the 2nd and 11th weeks. Statistical analysis was performed using non-parametric tests (Friedman and Wilcoxon, P < 0.05). We found no significant differences in PAL between intervention periods, and participants spent the majority of their awake time in sedentary activities. However, the exercise programme generated a significant 14.8% increase in VO₂ peak and a 15% reduction in fructosamine. The exercise programme had no compensatory effects on PAL in type 2 diabetes patients, but improved their cardiorespiratory fitness and glycaemic control.  相似文献   

‘The voice inside herself’: transforming gendered academic identities in educational administration     

Janice Wallace 《Gender and education》2015,27(4):412-429

This paper traces the academic identity formation(s) of 10 Canadian female academics whose disciplinary knowledge is in the field of educational administration. We trace the ways in which discourses of gender, institutional power, and other cultural and social influences shaped their sense of themselves as academics in the highly patriarchal domain of the academy as an institution as well as within the discourse(s) of educational administration in faculties of education. In doing so, we discuss the ways in which these women's entry into academia transformed identity possibilities for themselves and others. We conclude that these women share a commitment to rigorous scholarship and to the values of equity and social justice. The way in which they engage with those values in their work and lives has been taken up in the particular institutional and personal circumstances of their academic lives and has been shaped by the effects of normative discourses of gender. The result, individually and cumulatively, has been transformative on the individuals, within the institutions in which they have worked, and on the scholarship of Canadian educational administration.  相似文献   

Establishing the critical elements that determine authentic assessment     

Kevin Ashford-Rowe  Janice Herrington  Christine Brown 《Assessment & Evaluation in Higher Education》2014,39(2):205-222

This study sought to determine the critical elements of an authentic learning activity, design them into an applicable framework and then use this framework to guide the design, development and application of work-relevant assessment. Its purpose was to formulate an effective model of task design and assessment. The first phase of the study identified from the literature critical elements that determined assessment as being authentic, and presented these to practitioners and experts for feedback. In phase two, it codified the elements into a framework that was then applied to the redesign of assessments in an army course. Phase three involved student evaluation of the redesigned assessment activities. This led to further review and revision of elements in phase four. The study outcomes suggest that it is possible, by identifying and codifying individual elements, to determine the ways in which the authenticity of an individual assessment activity might be enhanced. The paper concludes with a literature update on the framework elements that lead to suggestions for further research.  相似文献   

Documentation: A Hard to Reach Place     

Janice Kroeger  Terri Cardy 《Early Childhood Education Journal》2006,33(6):389-398

Some educators experience difficulty documenting young children’s work in early childhood settings because of a limited understanding of the importance of documentation, what or how to document, and the effective use of documentation; limited resources (time, tools, and assistance); or predetermined curricular guidelines. Some teachers, especially inexperienced early years teachers, have trouble engaging with children and documenting simultaneously, revealing a crucial misunderstanding about the purpose of documenting. Teachers at Reggio Emilia-inspired schools throughout the United States use many forms of documentation to enhance the qualities of children’s experiences in preschool classrooms. This article addresses the dilemmas teachers face in implementing documentation in order to assist them as they move from standards-based teaching and teacher-determined content to a more constructivist approach to teaching. Ideas for using documentation shared by the authors will allow young children to construct their own knowledge and curiosity, making learning more meaningful to them and more visible to others.
