This study examines how art museumspurchasing policy influences the auction prices ofpaintings. Using a cross section of non-speculativetransactions during the period 1820–1970, we findconsiderable empirical support for the hypothesisthat public museums outside the U.S. pay above averageprices in auction markets providing higher thanaverage yields to private sellers. The typical U.S.private museums appear to be more restricted byfinancial constraints and the development of thegeneral economic conditions than their publiccounterparts.  相似文献   

Pupil Speech during Morning News: the effects of reducing teacher questions and increasing pauses and praise     

Dennis W. Moore  Tony Knott  Stuart McNaughton 《教育心理学》1989,9(4):311-320

Classroom discourse patterns were examined in the morning news sessions of a primary school classroom. The effects of reducing teacher questions and increasing rates of teacher pauses, praise and directives were investigated. Child words spoken and child expansions were recorded, as well as class call‐outs and teacher control statements. Frequencies of child words spoken showed no significant changes across the phases of the study. However, reducing teacher questions and increasing teacher pauses significantly decreased child expansions, while reducing teacher questions and increasing teacher praise significantly increased child expansions. Replacing teacher questions with directives had no significant effect upon child expansions. Class call‐outs and teacher control statements showed no significant changes across the intervention phases. The results of this study suggest that, for this teacher and class, teacher questions may be decreased without adversely affecting either child utterances or class behaviour, and that replacing questions with praise may increase children's contributions — particularly in the form of verbal expansions — to morning news talks.  相似文献

The Multiple Faces of Visual Arts Education     

Lars Lindström 《The International Journal of Art & Design Education》2011,30(1):7-17

This article identifies recent, mainly Nordic, research approaches to visual arts education. A concept map was developed as a heuristic tool in order to highlight salient traits and blind spots. Contemporary research typically has its origin either in education or in the art world, with an emphasis either on art as language or on art as text. These two dimensions were used to organise the studies and to select representative exemplars in different domains. The framework helped to chart the knowledge base of, and research approaches to, visual arts education. However, the result of blending subject matter and pedagogy tended to be a ‘mixture’ of viewpoints rather than emerging domains of subject‐specific pedagogical knowledge (Lee Shulman: an ‘amalgam’).  相似文献   

Selection for special education services: the role of gender and socio-economic status     

Marianne Nilsen Kvande  Jay Belsky  Lars Wichstrøm 《欧洲特需教育杂志》2018,33(4):510-524

Children from some demographic groups disproportionately receive special education (SE) services. Due to methodological shortcoming in existing work, it remains unclear whether this is due to real differences in academic needs or cultural selection/bias. Hence, in a community sample of 1250 Norwegian children, we examined the role of third grade SE services, academic test scores, behavioural problems, and teacher’s level of helplessness in mediating the effect of family socio-economic status (SES) and students’ gender on fifth-grade SE services. Results revealed no direct effects of either gender or SES on fifth-grade SE, but four mediated pathways were identified: (1) Boys had a greater likelihood of receiving fifth-grade SE services when (a) they previously received SE and (b) they experienced more ADHD symptoms, both in third grade. (2) Students from low-SES families were more likely to receive SE services in fifth grade when (a) they performed poorly in math in third grade and (b) their teacher reported greater feelings of helplessness when teaching these students. The findings are discussed with respect to the differential-needs hypothesis, mechanisms of cultural selection and the possibility of gendered selection for SE at younger ages.  相似文献

From safe spaces to communities of disagreement     

Lars Laird Iversen 《British Journal of Religious Education》2019,41(3):315-326

The idea of the classroom as a ‘safe space’ has been popular in education for at least two decades. More recently, the term has also been used by religious education scholars not least in the wake of the use of the term in the influential Council of Europe publication ‘Signposts’. In this article, I want to question the usefulness of the term ‘safe space’ within RE. The argument is not against many of the pedagogical aims and strategies that are referred to by the term ‘safe space’. However, the term is ambiguous, fraught with politicised controversy and promises more than in can deliver. These problems cannot be easily fixed by defining the term anew. The article is not only critical in its aim. It presents an alternative strategy. In the conclusion of the article, I suggest construing the RE classroom as a community of disagreement.  相似文献   

Phosphate loading and the effects on VO2max in trained cyclists     

I Stewart  L McNaughton  P Davies  S Tristram 《Research quarterly for exercise and sport》1990,61(1):80-84

It is known that an increased level of red blood cell 2,3-diphosphoglycerate (DPG) shifts the oxyhemoglobin dissociation curve to the right, thus allowing a greater unloading of oxygen at the tissue level. It has been hypothesized that phosphate might help increase VO2max by increasing 2,3-DPG level. Eight trained cyclists underwent three cycle ergometer tests (control, placebo, and experimental) to determine whether phosphate ingestion had any positive effect on VO2max, time to exhaustion, serum 2,3-DPG, and serum phosphate levels. We found no change between the control, placebo, or experimental conditions in pretest serum phosphate levels, but we did find increases in 2,3-DPG levels in the phosphate condition (p less than .05), which suggests that even a small amount of phosphate could increase levels of 2,3-DPG. We also found significant differences in VO2max between the control (p less than .05) and placebo (p less than .02) conditions and also in time to exhaustion between the three conditions (p less than .05). We suggest that phosphate may have an ergogenic effect, but clearly more work needs to be undertaken to ascertain the amount of phosphate required and the magnitude of the effect.  相似文献   

Managing the teaching–research nexus: ideals and practice in research-oriented universities     

Lars Geschwind  Anders Broström 《高等教育研究与发展》2015,34(1):60-73

This paper demonstrates that while ideals of close linkages between research and teaching are widely embraced in research-oriented universities, a practice of division of labour between teaching-oriented and research-oriented staff persists. In an investigation of how the research–teaching nexus is managed at three Swedish universities, we identify a perceived misalignment between institutional incentives for individual academic staff and the needs of teaching. Under pressure from such tensions, managers are forced to deploy pragmatic strategies for the staffing of undergraduate education tasks. This includes allowing research needs and agendas to take priority over teaching needs. While managers seek to secure the participation of senior researchers in education, they often actively prefer to delegate the bulk of teaching activities to less research-active staff. Such strategies seem to reinforce existing patterns of division of labour among academic staff.  相似文献
