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

One impact of globalisation has been the expansion of higher education to meet changing current socio‐economic and political requirements. This expansion places considerable stress on the public purse and many states have turned to alternative solutions. In China, a new phenomenon has emerged: independent higher education institutions that complement public and private institutions in helping to cater for the expanded numbers of students. These independent institutions are formed through partnerships between existing institutions and the business sector. After analysing the political, socio‐economic and cultural contexts that shape the policy of developing independent institutions, this paper explores the dilemmas and challenges that have arisen at the implementation level and critiques some of the solutions that have been found. 相似文献

This study investigated the evolution of physical and technical performances in the English Premier League (EPL), with special reference to league ranking. Match performance observations (n = 14,700) were collected using a multiple-camera computerised tracking system across seven consecutive EPL seasons (2006–07 to 2012–13). Final league rankings were classified into Tiers: (A) 1st–4th ranking (n = 2519), (B) 5th–8th ranking (n = 2965), (C) 9th–14th ranking (n = 4448) and (D) 15th–20th ranking (n = 4768). Teams in Tier B demonstrated moderate increases in high-intensity running distance while in ball possession from the 2006–07 to 2012–13 season (P < 0.001; effect size [ES]: 0.68), with Tiers A, C and D producing less pronounced increases across the same period (P < 0.005; ES: 0.26, 0.41 and 0.33, respectively). Large increases in sprint distance were observed from the 2006–07 to 2012–13 season for Tier B (P < 0.001; ES: 1.21), while only moderate increases were evident for Tiers A, C and D (P < 0.001; ES: 0.75, 0.97 and 0.84, respectively). Tier B demonstrated large increases in the number of passes performed and received in 2012–13 compared to 2006–07 (P < 0.001; ES: 1.32–1.53) with small-to-moderate increases in Tier A (P < 0.001; ES: 0.30–0.38), Tier C (P < 0.001; ES: 0.46–0.54) and Tier D (P < 0.001; ES: 0.69–0.87). The demarcation line between 4th (bottom of Tier A) and 5th ranking (top of Tier B) in the 2006–07 season was 8 points, but this decreased to just a single point in the 2012–13 season. The data demonstrate that physical and technical performances have evolved more in Tier B than any other Tier in the EPL and could indicate a narrowing of the performance gap between the top two Tiers. 相似文献

This essay reviews two recently published American books about masculinity politics—Michael Kimmel's pro-feminist Manhood in America and his edited collection The Politics of Manhood —in order to comment critically on the current debate underway in various parts of the world on 'boys' and their schooling which sees them as the 'new victims' of the educational process. 相似文献

This paper offers a critical analysis of Dubinsky et al. (1994) and proposes, as an alternative to the four axioms and the standard definitions, that permutation and symmetry may be regarded as the fundamental concepts of group theory. 相似文献

This article is a conceptual one designed to start dialogue on educational issues that are unfolding amidst the changes in other sectors of our society such as production, services, and recreation. We first present an overview of the fundamental but profound changes evidenced in our society and then discuss the nature of these changes and their impact on human ability to function effectively within such an environment. In light of the complexities such as uncertainties and dualistic/multiple perspectives and incongruities, we propose that a model for pedagogy and curriculum development should adopt critical thinking as the key attribute—because it has the potential to deliver an education system for the new world order. 相似文献

This paper is a reflection on the current policy moment in educational research in Australia in the context of globalisation. Set against a consideration of the emergent structure of feeling, the paper draws on three case studies of research to draw out some lessons for educational researchers and the research community. The argument is put that the dangerous ‘we’ of AARE needs to support increased funding for education and for educational research and, for the latter, to support a range of funding sources, types of research, methodologies and dissemination approaches. Increasingly there are pressures upon such eclecticism because of governmental attempts to ‘instrumentalise’ relationships between educational research and practitioner needs as perceived by governments. While such research is necessary, there is also a need within a democratic polity for research framed by agendas set by researchers that critiques government-directed developments. The paper argues there is a complex relationship amongst researchers and educational policy and pedagogical practitioners and as such the concept of ‘impact’ as applied to educational research requires substantial theorising. Contemporary research policy has tended to inhibit the dissemination of academic research to educational practitioners, while educational policy has tended, inappropriately in the argument of the paper, to construct teachers as the mere recipients of policy and research done elsewhere. 相似文献
