ABSTRACT

Control 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

Similar to individuals, organizations display characteristics that speak to qualities and abilities. Our guest writer, Lisa Bodenheimer, discusses a trait that is critical for library organizations during this period of constant change and transformation. Resiliency is the ability to rebound and flex as circumstances shift enabling an organization to thrive and adjust during difficult times. This skill is typically developed through experiences, but, as Ms. Bodenheimer outlines, organizations are able to strategize in order to build employee and organizational resilience. Such a proactive approach will enable a library organization to better weather challenging situations and times as difficulties will enviably occur. The following article provides practical suggestions for library organizations that will enable them to be more successful while leading and managing in a changing environment.  相似文献

The new Special Educational Needs and Disability legislation in the Children and Families Act 2014 intends to raise the aspirations of young people with special educational needs and their families, and improve their life outcomes. But what do raised aspirations and better outcomes look like for young people who have a life‐limiting impairment? This article draws on data from a parent evaluation of a lottery‐funded Transition to Adulthood project for boys with Duchenne muscular dystrophy (DMD), called ‘Takin’ Charge’, focusing in particular on whether or not the project helped parents of boys with DMD prepare for the future. Key themes that emerged were the importance and novelty of older role models with DMD in the project who were able to share their journeys into adulthood, the support between families that the project enabled, the meaning of family resilience and aspirations for a normal life. The use of solution‐focused questioning with families affected by a life‐limiting impairment is also explored.  相似文献

In sub-Saharan Africa, where there is limited financial and human capital, it is important to examine how social relationships may serve to promote or undermine human capital formation. However, little is known about the contributions of social relations to human capital development, especially in terms of academic achievement in Africa. This study examined how variations in key aspects of social relations among teachers; between teachers and students; between principals, teachers, parents and students affect achievement in mathematics among sixth graders in 70 schools in six districts in Kenya. We modeled mathematics achievement as a function of measures of social perception and support while adjusting for school-, classroom- and student level background characteristics. We found that net of teacher subject knowledge and background characteristics, teachers who display commitment to teaching by always correcting homework and keeping students engaged during math lessons had their students performing better. Teacher absenteeism and lack of interest in teaching were negatively associated with performance in math. Lack of parental involvement in the classroom also had negative effects on grades. At the school level, the level of engagement of the principal, measured by supervision of teachers and good interpersonal interactions with parents had positive effects on math achievement. Schools where parents provided material and financial support had better grades, while student delinquency and absenteeism negatively affected grades.  相似文献

Using a participatory learning approach, we report on the delivery and evaluation of a climate change and risk assessment tool to help manage water risks within the agricultural sector. Post-graduate water-professional students from a range of countries, from both developed and emerging economies were involved in using this tool. Our approach included participative learning tools – group discussion, software, and risk matrices. The materials developed met the needs of the students, allowing these students to incorporate their learning and adapt the package of materials for use in their home countries. Analysis of evaluations show that the tools and materials are particularly useful and emphasizes the need for sound learning materials and tools, funding to deliver training, and policy support to accelerate education and adoption of authentic climate change adaptation practices. The expected benefits for water professionals about climate change will be translated into improved socioeconomic and environmental outcomes if adopted.  相似文献

In this article, author Bill Ptacek says that the future is now, and, at least from the 1970s through today, in the field of early childhood work, the future has come so fast that it is constantly upon us. That reality means that those concerned about young children in libraries have been about adaptation on a continuing basis. In this world of rapid change, innovation is constant: City firefighters come to the libraries in uniform to read stories to children, library outreach specialists take programs to daycare centers in their communities, and staff members create a space in a library devoted to early childhood reading. This tradition of rapid change means that the early childhood staff of most large public libraries in North America is changing for the future on a regular basis. The work unit should be considered seriously as one model for 21st century public library reform.  相似文献

[目的/意义] 组织氛围优化有助于提升馆员对图书馆的满意度和馆员的工作热情。案例分析有助于在更多图书馆推广组织氛围测评,进而为管理优化决策提供支持。[方法/过程] 南京农业大学图书馆借鉴美国图书馆界开展ClimateQUALTM测评的做法,在对ClimateQUALTM量表进行本地化改造的基础上,分别于2011和2015年对图书馆组织氛围开展量化测评,通过分析数据寻找存在的问题并不断优化管理方案。历经4年多时间,完成图书馆组织氛围的优化探索过程。[结果/结论] 前后两次测评数据对比显示,2015年得分较2011年整体有所提升,同时集思广益、创新、激励竞争、用户服务和团队合作5个指标得分明显提升,说明组织氛围测评的必要性和管理创新举措的有效性。  相似文献
