This paper presents the results of a light levels survey conducted at the Donald W. Reynolds Center for American Art and Portraiture in Washington DC. The museum space is shared by the National Portrait Gallery and the Smithsonian American Art Museum. After six years of extensive renovations, the building reopened to the public in July 1, 2006. The structure was not originally designed to house a museum collection since it contains numerous openings such as windows, doors and skylights, which provide a path for natural radiation to enter the building and come in contact with the artworks. From a preventive conservation standpoint, this is an important problem since sensitive works of art in the collection may be subjected to damage caused by light exposure. Environmental data loggers installed throughout the museum were programmed to take successive measurements every 10 min for 24 h a day, 7 days a week and 52 weeks a year. This light levels assessment started in November 1, 2007 and finished in October 31, 2008. This study presents a new method for determining natural radiation exposures registered in exhibition spaces that rely on both electric lighting and natural lighting, considering the growing trend of using daylight illumination in museums. 相似文献

This research explores business internationalisation as a process of recognising and exploiting business opportunities in an international context and uses Spain's natural stone industry as a case study. We differentiate internationalisation into two stages: opportunity identification and subsequent opportunity exploitation. We focus on the initial identification stage to determine the impact of entrepreneurs’ cognitive variables when gathering relevant information for internationalisation of the firm, highlighting the role of entrepreneurs’ alertness, the centre of interest, causal logic, and prior experience. We also examine the importance of the entrepreneur's environment, social networks, and institutional setting. In our empirical analysis, we find that although interested in internationalisation, entrepreneurs in the natural stone industry devote very little time and effort to gathering information. As a result, decisions related to internationalisation are restricted by uncertainty and a poor understanding of the appeal, barriers, and available support services. 相似文献

The Experience Corps?, a community-based intergenerational program, was developed to promote the health of older adults, while simultaneously addressing unmet social and academic needs in public elementary schools. The model was designed to draw on, and potentially activate, the wisdom of older adults. This paper explores the nature of wisdom-related knowledge and how older adults may apply such knowledge when tutoring and mentoring young children, as well as the potential for the intergenerational transmission of wisdom from the older adult volunteers to the school children being mentored by them. Developing an understanding of these issues may provide a basis for the creation of more extensive wisdom-generating opportunities for both older and younger generations. 相似文献

道德规范与图书馆事业 总被引:1,自引:0,他引:1
美国图书馆协会的《职业道德规范声明》提出了以图书馆事业为中心的具体原则,其《图书馆权利法案》则明确了图书馆的责任和义务。目前,美国社会和政治环境的变化为图书馆职业带来了越来越多的忧虑和压力。"9·11"后出台的《爱国者法案》明显与图书馆职业道德规范中所阐述的重要原则相冲突。因此,美国图书馆协会决心抵制《爱国者法案》对知识、信息自由开放以及行使个人隐私权的限制。 相似文献

This study investigates how different stakeholders in Norway experienced a government-initiated, large-scale policy implementation programme on Assessment for Learning (AfL). Data were collected through 58 interviews with stakeholders in charge of the policy; Ministers of Education and members of the Directorate of Education and Training in Norway, and the main actors such as municipality leaders, teachers, school leaders and students. Successful implementation of AfL processes was found in municipalities where there were dialogue and trust between the municipality level, school leaders, teachers and students and where the programme was adapted to the local context. Implementation was challenged when the policy was interpreted as a way of controlling the schools. Despite the successful implementation in some municipalities, the programme did not have any effect upon students’ learning outcome, as measured on national tests in reading and mathematics. The results are discussed in relation to how local assessment cultures with particular characteristics influence governing, accountability and trust. 相似文献

The aim of this study was to analyse the characteristics of the asymmetries in the dominant and non-dominant limbs when kicking stationary and rolling balls. Ten experienced Brazilian amateur futsal players participated in this study. Each participant performed kicks under two conditions (stationary ball vs. rolling ball) with the dominant and non-dominant limbs (five kicks per condition per limb). We analysed the kicking accuracy, ball and foot velocities, angular joint displacement and velocity. The asymmetry between the dominant and non-dominant limbs was analysed by symmetry index and two-way repeated measures ANOVA. The results did not reveal any interaction between the condition and limb for ball velocity, foot velocity and accuracy. However, kicking with the dominant limb in both kicks showed higher ball velocity (stationary ball: dominant – 24.27 ± 2.21 m · s?1 and non-dominant – 21.62 ± 2.26 m · s?1; rolling ball: dominant – 23.88 ± 2.71 m · s?1 and non-dominant – 21.42 ± 2.25 m · s?1), foot velocity (stationary ball: dominant – 17.61 ± 1.87 m · s?1 and non-dominant – 15.58 ± 2.69 m · s?1; rolling ball: dominant – 17.25 ± 2.26 m · s?1 and non-dominant – 14.77 ± 2.35 m · s?1) and accuracy (stationary ball: dominant – 1.17 ± 0.84 m and non-dominant – 1.56 ± 1.30 m; rolling ball: dominant – 1.31 ± 0.91 m and non-dominant – 1.97 ± 1.44 m). In addition, the angular joint adjustments were dependent on the limb in both kicks (the kicks with non-dominant limb showed lower hip external rotation than the kicks with the dominant limb), indicating that the hip joint is important in kick performance. In conclusion, the kicks with the non-dominant limb showed different angular adjustments in comparison to kicks with the dominant limb. In addition, kicking a rolling ball with the non-dominant limb showed higher asymmetry for accuracy, indicating that complex kicks are more asymmetric. 相似文献
