Data were collected from a sample of school psychologists and teachers after termination of a teacher consultation experience. Stepwise regressions were performed on the data to determine which psychologist and teacher variables were related to teacher satisfaction with the school psychological consultation. The single most significant main effect on teacher satisfaction was the teacher's perception of the psychologist's facilitativeness. 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

What conservation strategies can be used for Tino Sehgal's 2005 work This Is So Contemporary, and what are their relations to oral traditions? Sehgal's art leaves no material traces, as the artist resists the use of photos and videos acting as a documentary surrogate for his work. This paper will explore how Sehgal's non-written documentation strategies connect to the work of Yumutjin Wunungmurra, a contemporary artist and ceremonial leader from Northeast Arnhem Land, Australia. The connection will be tracked through the role of caretaker and custodian that features in the workflow of both artists. The paper asks whether the performance-based strategies discussed can support the notion of conservation as a social process with multiple stakeholders. 相似文献

This paper considers the history of the emergence and development of cooperative cataloging in Russia and abroad and presents the first projects and programs in the field of cooperative cataloging: CONSER, NACO, BIBCO, and PCC. It elucidates the activity of the OCLC Center and Consortium of European Scientific Libraries, which are the first-rate international cooperative associations, as well as the ARBIKON Association and LIBNET centers which are Russian centers of cooperative cataloging. 相似文献

The main aspects of the creation of a monitoring system for the research activities of the members of a higher-education institution are considered. The scientific activities of the lecturers and members of Turgenev Orel State University is used as the basis. It is expected that this system will be an efficient tool for optimal managerial decisions at all levels. 相似文献
