ABSTRACT Many museums are housed in historic buildings, sometimes the building itself is part of the museum collection. Creating a stable environment by providing a nearly constant temperature and relative humidity at correct levels decreases the risk of object degradation. Maintaining this steady indoor environment, however, increases energy consumption and risks to the historic building. Museum display cases offer a solution to the mitigation of risks to which valuable objects may be subjected by providing an extra layer of protection to indoor climate fluctuations. The Anne Frank House is a historic house museum located in Amsterdam. The museum has undergone several renovations in the last years to deal with an increase in the number of visitors to over 1.2 million a year. The original diaries and other documents of Anne Frank are permanently on display in the Anne Frank House. With the recent refurbishment the possibility arose to design a new state-of-the-art display case. This study presents the results of the experimental research related to the design, performed in-situ. The temperature and relative humidity in the new exhibition space and inside the new display cases were monitored to gain insight into the hygrothermal behavior of these controlled environments. A complementary numerical study was performed to investigate effects of dynamic climate control of the exhibition gallery and climate conditions in the display case under various circumstances. Four main conclusions are presented in this paper. The investigated display case design is able to provide a stable relative humidity environment by means of silica gel, while using an active box-in-box climate control system to create stable temperature conditions. The inner case temperature depends on the temperature supplied by the display case air handling unit. Protocols must be in place in case of malfunction or failure of the climate control system of the display case. The air handling unit of the case needs to be shut off to create a passive environment for the objects on display until necessary actions are taken. Exhibition gallery set points can be less stringent when susceptible museum objects are on display in the display case. The environments are separated and provide an opportunity for energy saving set point strategies. The last conclusion drawn is that the numerical study provides valuable insight into imposing dynamic control of set points for temperature and relative humidity in the exhibition gallery and the effect on the display case environment. 相似文献

The purpose of this study was to examine whether scientific mobility, either between countries or between affiliations has an effect on researchers’ productivity and impact. In order to investigate this issue, we examined the relationships between the number of institutional affiliations and countries of the top 100 authors in seven disciplines. The selected authors’ profiles contained the number of affiliations and countries each author is assigned. We studied the number of affiliations and countries and compared them to three bibliometric indicators: the number of publications in international, peer-reviewed journals, h-index and Field Weighted Citations Impact. Our findings show that although there are differences in the relationship between mobility, productivity and impact between disciplines, mobility between at least two affiliations has an overall positive effect on both output and impact while mobility between countries does not. Therefore, in most disciplines positive impact and productivity effects are tracked in affiliation mobility within a single country. 相似文献

The Purpose of this study was to examine effectsof group discussion of a medical problem on the comprehension of a subsequentproblem-relevant text by first year medical students.Forty-eight first-year medical students were randomly assigned toone of two conditions: The experimental group discussed a problem of blood pressureregulation, where the control group discussed a problem of vision. Subsequently, allstudents studied a text on the physiology of blood pressure regulation. Finally, a freerecall test was administered. Numbers of propositions accurately recalled were analyzed usinganalysis of variance (ANOVA). Students who discussed the blood pressure regulationproblem recalled 25% more from the text than those who discussed the control problem.This difference was statistically significant. The present study represented thefirst truly randomized trial in the ecologically valid context of a medical curriculum. Itdemonstrated the positive effects of problem-based tutorial group discussion on thecomprehension of text. It confirmed earlier findings from laboratory studies thatproblem-based learning, in addition to positive emotional and motivational long-term effectswell-documented in the literature, also has positive effects on learning. 相似文献

School readiness of children with special educational needs (SEN) is still understudied. The present study examined how the presumed bidirectional relationship between impaired academic performance (AP) and internalising problems (IP) could be favourably influenced. In this regard, it was assumed that children’s adaptive emotion regulation plays a crucial role, as it was shown to be independently related to improved AP and fewer IP. However, to gain stronger evidence for this assumption, it should be further clarified whether adaptive emotion regulation, AP and IP are also jointly associated and, if so, how this is reflected in children with SEN. To explore these issues, two different models were tested in a cross-sectional pilot including 61 Flemish elementary school children with SEN (39 boys and 22 girls, mean age = 10.0 years old). Teachers reported on adaptive emotion regulation, AP and IP. The results indicated that AP partially mediated the relationship between adaptive emotion regulation and IP (Model 1), while IP fully mediated the relationship between adaptive emotion regulation and AP (Model 2). Practical implications, strengths and limitations were discussed. 相似文献

This paper examines the propensity to attain a Ph.D. degree at the five largest universities in Flanders, the Dutch speaking
part of Belgium. It provides insight into the rate at which junior scholars appointed at the universities involved attained
their Ph.D.-degree, and the duration of the doctoral training period. Cox’s regression model was applied to statistically
analyse the influence of a number of ‘demographic’ and ‘merit’ variables, and variables related to funding source and type
of appointment of the junior scholarly staff. Large differences in Ph.D. durations and attainment rates were found across
funding sources, research disciplines and types of appointments. The policy background and implications are discussed briefly. 相似文献

Collaboration between practitioners and researchers can increasingly be observed in research and development (R&D) projects in secondary schools. This article presents an analysis of cross-professional collaboration between teachers, school leaders and educational researchers and/or advisers as part of R&D projects in terms of three dimensions: reasons for collaboration, the division of roles and tasks, and the communication structure. Data were collected in interviews with participants from 12 Dutch projects, from documents and from meetings with participants. The results show that the parties involved can have the same reasons for cross-professional collaboration but that the external educational experts may also have additional objectives. Roles and tasks were divided in different ways, depending on who directs and guides the research and development, and whether teachers were involved as teacher researchers in the project. The communication structure appeared to be linked to the division of roles and tasks, but also to the number of participants in the project. The three dimensions proved to be valuable viewpoints to study cross-professional collaboration in R&D projects in Dutch secondary education. Furthermore, we distinguished four types of cross-professional collaboration in R&D projects. These types differ in the extent to which the school or the external party direct and guide the project: (a) School-directed collaboration; (b) School- and researcher-directed collaboration; (c) School- and adviser-directed collaboration; (d) Researcher-directed collaboration. Our findings can support participants to consciously choose a particular type of cross-professional collaboration that fits their purposes and specific situation. 相似文献
