In the museum context, curators and conservators often play a role in shaping the nature of contemporary artworks. Before, during and after the acquisition of an art object, curators and conservators engage in dialogue with the artist about how the object should be exhibited and conserved. As a part of this dialogue, the artist may express specifications for the display and conservation of the object, thereby fixing characteristics of the artwork that were previously left open. This process can make a significant difference to the visual appearance of the work, the nature of the audience's experience, and how the work should be interpreted. I present several case studies in which the nature of the artwork has been shaped by such dialogues, and discuss principles for resolving cases in which there is a conflict between instructions specified by the artist and those adopted by the museum. 相似文献

ABSTRACT The aims of the present study were to provide an in-depth comparison of inter-limb asymmetry and determine how consistently asymmetry favours the same limb during different vertical jump tests. Eighteen elite female under-17 soccer players conducted unilateral squat jumps (SJ), countermovement jumps (CMJ) and drop jumps (DJ) on a portable force platform, with jump height, peak force, concentric impulse and peak power as common metrics across tests. For the magnitude of asymmetry, concentric impulse was significantly greater during the SJ test compared to CMJ (p = 0.019) and DJ (p = 0.003). No other significant differences in magnitude were present. For the direction of asymmetry, Kappa coefficients revealed fair to substantial levels of agreement between the SJ and CMJ (Kappa = 0.35 to 0.61) tests, but only slight to fair levels of agreement between the SJ and DJ (Kappa = ?0.26 to 0.18) and CMJ and DJ (Kappa = ?0.13 to 0.26) tests. These results highlight that the mean asymmetry value may be a poor indicator of true variability of between-limb differences in healthy athletes. The direction of asymmetry may provide a useful monitoring tool for practitioners in healthy athletes, when no obvious between-limb deficit exists. 相似文献

This paper reports on efforts aimed toward the development of more effective procedures for identifying mothers who are at elevated risk for problems in parenting. We present data from two independent samples of known maladaptors and corresponding comparison mothers and report on our attempts to cross-validate a promising screening instrument composed of items that index social support and parenting attitudes. The resultant 20-item scale correctly identified over 90% of maladaptive and comparison mothers. When this scale was cross-validated on a second independent sample of maladaptors and comparison mothers, it was again almost 90% accurate. Issues concerning the field application of this promising instrument are discussed and its possible limitations are considered. 相似文献

Selective universities regularly employ policies that favor children of alumni (known as legacies) in undergraduate admissions. Since alumni from selective colleges and universities historically have been disproportionately white, admissions policies that favor legacies have disproportionately benefited white students. For this reason, legacy policies lead to additional costs in terms of reductions in racial diversity. As larger numbers of minority students graduate from colleges and universities and have children, however, the potential pool of legacy applicants will change markedly in racial composition. This analysis begins with a review of the history and objectives of the preference for children of alumni in undergraduate admissions. We then consider the specific case of the University of Virginia and employ demographic techniques to predict the racial composition of the pool of potential legacy applicants to the university. Significant changes in the racial composition of classes that graduated from the University of Virginia from the late 1960s through the 1970s foreshadow similar changes in the characteristics of alumni children maturing through the next two decades. 相似文献

This study focuses on an industrial, commercial and community experience programme within a full time, one year postgraduate teacher training course. Acknowledging the heterogeneous experiences brought to this course by the students, an attempt was made to detect links between the students’ prior experience and their experience of the industrial, commercial and community programme. The students completed questionnaires before and after a placement and the findings are described. These findings contribute to an evaluation of the programme and suggest a number of important questions for those responsible for designing teacher education courses. 相似文献

Charles Perrow used the term “normal accidents” to characterize a type of catastrophic failure that resulted when complex,
tightly coupled production systems encountered a certain kind of anomalous event. These were events in which systems failures
interacted with one another in a way that could not be anticipated, and could not be easily understood and corrected. Systems
of the production of expert knowledge are increasingly becoming tightly coupled. Unlike classical science, which operated
with a long time horizon, many current forms of expert knowledge are directed at immediate solutions to complex problems.
These are prone to breakdowns like the kind discussed by Perrow. The example of the Homestake mine experiment shows that even
in modern physics complex systems can produce knowledge failures that last for decades. The concept of knowledge risk is introduced,
and used to characterize the risk of failure in such systems of knowledge production. 相似文献
