ABSTRACTControl of relative humidity (RH) for collections care is challenging in U.K. historic houses because they are often highly ventilated with poor heat retention, a porous building fabric and naturally tend to high (60–80%) RH if unheated. The significance of the building means that large-scale modifications and installation of air handling systems may be unfeasible and undesirable for the conservation of the building. In the late 1980s the National Trust, for English, Wales and Northern Ireland, investigated conservation heating as an RH control method that works with the natural environment of historic buildings, mimicking historic heating and requiring only modification of existing heating services or a light touch installation of new heating systems. The National Trust adopted conservation heating as its preferred method for environmental control in historic buildings from the 1990s. This method was presented at the IIC 1994 Ottawa congress on preventive conservation. Conservation heating has since been adopted by many historic house management organisations, particularly across north-west Europe, where it is well suited to the climate. This paper reviews conservation heating developments implemented by the National Trust since 1994, in response to a changing external context, new knowledge and developments in operational practice. 相似文献

ICF理念下残疾人康复服务人才队伍建设新探 总被引:1,自引:0,他引:1
近年来,我国残疾人康复服务的需求正在发生着改变,国际上一些新的有关残疾、健康、康复的理念也逐渐被我国康复领域的学者及从业人员所认识与接受。其中,《国际功能、残疾和健康分类》(ICF)的提出,让全世界对残疾与健康有了新的理解,也对残疾人的康复服务有了新的思考。我国残疾人康复服务人才正处于亟待发展壮大的阶段,因此从ICF的理念出发,以ICF理念对我国康复服务人才队伍建设的启示及残疾人对康复服务的需求为主要依据,搭建了适合我国康复服务的人才队伍,并深入分析了ICF对残疾人康复服务人才队伍建设的支持。 相似文献

Despite official endorsement of attachment principles in nursery work, these are often not translated into nursery practice. One possible reason for this is that staff training does not sufficiently address the personal implications and anxieties that children's attachments may entail for practitioners. Working from a psychoanalytic perspective on organisational functioning and group learning, this paper describes action research with a group of nursery heads who participated in a professional development programme designed specifically to explore emotional experience in professional work. The positive evaluations of the programme by heads and their staff are described including examples of experiential learning and of increased staff awareness about, and responsiveness to, the emotional experience of children. However, the research also concluded that sustained effectiveness of the model is likely to be dependent on an ongoing culture of attention to the emotional experience of nursery staff within nursery umbrella organisations. 相似文献

This article sets out to examine the effectiveness of five different post-16 study pathways and the impact that spending time away from education has on gaining employment associated with an undergraduate degree. It also explores advice and guidance for students looking at post-16 study options, higher education and employment. An initial online survey was used, followed by case studies to form a mixed-method approach. The findings suggest that a vocational pathway better prepares students for making decisions around employment and study in comparison to the more traditional A Level pathway. They also highlight that a period of one to four years after finishing post-16 study and starting undergraduate degree study is the most effective for students to gain employment associated with their undergraduate degree. Finally, it was found that most participants did not have positive experiences with advice and guidance regardless of their pathway. 相似文献
