This article draws on experiences of looking at art to consider the influence of social context on the production and consumption of art. I draw on art historical discourses and relate these to looking at art in art therapy and related organisational settings. I suggest that professional socialisation profoundly influences how practitioners look and think about what they see. I propose that attention to tacit knowledge about art, extending practices of looking to include contemporary discourse about audiencing, curating and display, and taking time for a long look at art and at the art made in art therapy and allied settings, can enliven and sustain practitioners' ‘ways of seeing’. 相似文献

In this study, we compared measured maximal heart rate (HRmax) to two different HRmax prediction equations [220 — age and 208 — 0.7(age)] in 52 children ages 7-17 years. We determined the relationship of chronological age, maturational age, and resting HR to measured HRmax and assessed seated resting HR and HRmax during a graded exercise test. Maturational age was calculated as the maturity offset in years from the estimated age at peak height velocity. Measured HRmax was 201 ± 10 bpm, whereas predicted HRmax ranged from 199 to 208 bpm. Measured HRmax and the predicted value from the 208 — 0.7(age) prediction were similar but lower (p < .05) than the 220 — age prediction. Absolute differences between measured and predicted HRmax were 8 ± 5 and 10 ± 8 bpm for the 208 — 0.7 (age) and 220 — age equations, respectively, and were greater than zero (p < .05). Regression equations using resting HR and maturity offset or chronological age significantly predicted HRmax, although the R2 < .30 and the standard error of estimation (8.2-8.5) limits the accuracy. The 208 — 0.7(age) equation can closely predict mean HRmax in children, but individual variation is still apparent. 相似文献

Screening and measurement of monoclonal (M) proteins are commonly performed using capillary zone electrophoresis (CZE). The identification of M-protein or monoclonal component (CM) is an essential requirement for diagnosis and monitoring of monoclonal gammopathies. The detection of CM has been largely improved by CZE. Capillary electrophoresis estimates CM more accurately, because absence of variation due to different dye binding affinities of proteins as instead seen with agarose gel electrophoresis. However, interferences can be present in CZE. This occurs because all substances absorbing at 200 nm can be identified. Recognition and handling of specimens exhibiting such interferences is essential to ensure accurate diagnostic and patient safety. We herein report on an unusual case of serum protein electrophoresis, to highlight that laboratory staff must be aware of and familiarise with the information provided by laboratory instruments. For example, in the case of serum indices, about specimen quality. 相似文献

There is a current national emphasis on science, technology, engineering, and mathematics (STEM). Additionally, many states are transitioning to the Next Generation Science Standards (NGSS), which encourage teachers to incorporate engineering in science classrooms as well as have their students learn science by doing science. Methods courses are also shifting to adequately prepare preservice science teachers in these areas. This study examines preservice science teachers’ pre- and post-ideal inquiry-based lesson plan scenarios before and after intervention in their Secondary Science Methods I and II courses. These preservice science teachers participated in a variety of opportunities to practice authentic science inquiry (ASI) pedagogical techniques as well as integrated STEM topics, with a particular emphasis on computer programming throughout their 80 h of Methods instruction. ASI is a type of inquiry where students learn science by conducting science research in a grade-appropriate manner. Thirty-eight preservice teachers’ scenarios were analyzed using a rubric from Spuck (2014) to determine the degree to which the ten components of ASI were included in scenarios pre- to post-instruction. Trends in ASI component inclusion are discussed. These findings indicate that preservice science teachers are proficient at writing inquiry-based lessons where they planned opportunities for their future students to collaborate, use scientific instrumentation, and collect and analyze data, but need additional support with developing student activities where students create testable questions, revise their question and methods, participate in peer review, and disseminate their results to their peers or the larger scientific community. Overall, the results suggest Methods instruction should reinforce preservice teachers’ focus on planning lessons which include opportunities for all ASI components. Interventions in the aforementioned areas of weak inclusion may be beneficial to preservice teachers. 相似文献
