This is the third in a series of articles exploring international trends in health science librarianship in the first decade of the 21st century. The invited authors were asked to reflect on developments in their country--viz. Austria, Belgium, France and the Netherlands. Future issues will track trends in the Nordic countries, Southern Europe and Latin America. JM. 相似文献

The concept of scaffolding refers to temporary and adaptive support, originally in dyadic adult–child interaction. It has become widely used, also in whole‐class settings, but often in loose ways. The aim of this paper is to theoretically and empirically ground a conceptualisation of whole‐class scaffolding so that it remains close to the origin of the scaffolding concept, but also provides scope for features not salient in one‐to‐one interaction. Drawing an analogy with Vygotsky's concept of Zone of Proximal Development we argue why the extension to whole‐class settings is justified. We further distinguish three key characteristics for whole‐class scaffolding—diagnosis, responsiveness and handover to independence—and illustrate these with examples from a teaching experiment focusing on whole‐class scaffolding language in a multilingual mathematics classroom (age 10–12). The empirical data led to a metaphorical distinction between online and offline enactment of key characteristics, during respectively outside whole‐class interaction. Diagnoses can namely also be made outside lessons, for instance by reading pupils' work; responsiveness can also be realised in adapting instructional activities; and handover to independence can also be fostered in the design of lessons. In addition to this layered nature (online vs. offline), whole‐class scaffolding is often distributed over time. Finally, whole‐class scaffolding is cumulative with pupils' independence emerging as the cumulative effect of many diagnostic and responsive actions over time. We suggest these three features are at the core of whole‐class scaffolding that is deliberately employed to foster long‐term learning processes. 相似文献

ABSTRACTThe purpose of this study was to describe the accelerometry-based characteristics of overall sedentary behavior (SB) and sitting among adults under free-living conditions. Thirty-six (mean age 47.6 years) volunteers carried a waist-worn accelerometer for ≥4 days with data ≥600 min/d during 14 consecutive days. A machine learning (ML) based method was used to classify the patterns of SB and sitting from raw 3D acceleration. The participants spent most (69.3%) of their waking time in SB, and a half (52.2%) of the SB was performed in a sitting posture. Men broke their overall sedentary time less often (4.1 vs. 6.1 bouts/h), but women sat more; however, women broke their sitting time as often as men (7.6 bouts/h). This study confirms that SB and sitting can be distinguished using ML methods, and more information about SB can be achieved when overall SB and sitting are analyzed separately in free-living conditions. 相似文献

The planning and production of a photo-play as a group project involves the natural discipline of a technical job and the through exploration of the subject under study. At the same time it provides a logical conclusion and presentation which is its own record of achievement and a source of legitimate pride to its makers. The photo-play also forms an entertaining and valuable recapitulation of the study for the group and is an effective teaching aid for use with other groups, taking advantage of that curious capacity of children to give more concentrated attention to the work of their peers than their teachers. 相似文献

Learner autonomy is a primary learning outcome of Higher Education in many countries. However, empirical evaluation of how student autonomy progresses during undergraduate degrees is limited. We surveyed a total of 636 students’ self-perceived autonomy during a period of two academic years using the Autonomous Learning Scale. Our analysis suggests that students do not perceive themselves as being any more autonomous as they progress through University. Given the relativity of self-perception metrics, we suggest that our results evince a “red queen” effect. In essence, as course expectations increase with each year, each student’s self-perceived autonomy relative to their ideal remains constant; we term this the “moving goalpost” hypothesis. This article corroborates pedagogical literature suggesting that providing students with opportunities to act autonomously and develop confidence is key to developing graduates who have the independence that they need in order to be successful in the workplace. 相似文献

Thermodynamic systems with variable mass, like liquid/vapor equilibria and chemical reactions, are represented as networks having discrete elements and connections using bond graph symbols. The mass bond has special properties which are explained by entropy and volume stripping and indicate the reason why the derivative of the free enthalpy, not the internal energy, is the driving effort of chemical reactions. Chemical friction is represented by RS-fields that dissipate power which is different from the observed heat rate of chemical reactions. Different reticulations apply to reactions near and far from chemical equilibrium; their relation to experimental reaction kinetics and order of reaction is discussed. 相似文献

Sleep of professional athletes: Underexploited potential to improve health and performance 总被引:1,自引:1,他引:0

Sleep disorders have become increasingly prevalent affecting health and working ability. Restorative sleep may be considered important for athletes’ successful recovery and performance. However, some athletes seem to experience major problems in sleeping. Thus far, there is limited scientific information about their sleep. This study aimed to evaluate the quality of sleep and the prevalence of sleep disorders as well as the impact of a structured sleep counselling protocol in professional athletes. A total of 107 professional ice hockey players participated in the study. The exploratory observational 1-year follow-up study consisted of questionnaire-based sleep assessment followed by general sleep counselling and, when needed, polysomnography and an individual treatment plan. One in every four players was found to have a significant problem in sleeping. All athletes considered sleep essential for their health and three in every four players considered that counselling would improve their performance. Counselling and individual treatment were found to improve significantly the quality of sleep with the mean alteration of 0.6 (95% CI 0.2–1.0, P = 0.004) in a scale from 0 to 10. Our results support that sleep problems are common in professional athletes. However, systematic examination, counselling and individual treatment planning can improve the quality of their sleep. 相似文献
