New Documents on the History of the Russian Historical Archive Abroad in Prague

The article discusses a newly-discovered collection of administrative documents and correspondence from the Russkii zagranichnyi istoricheskii arkhiv [Russian Historical Archive Abroad], which was active 1924–1945. The collection is housed in the Slavonic Library in Prague. It is important for both the history of the archive itself and the history of the Russian emigration. An inventory list of the collection is now available on the library's Web site.     

Vibrotactile feedback for correcting aerodynamic position of a cyclist

ABSTRACT

Guidance to maintain an optimal aerodynamic position is currently unavailable during cycling. This study used real-time vibrotactile feedback to guide cyclists to a reference position with minimal projected frontal area as an indicator of aerodynamic drag, by optimizing torso, shoulder, head and elbow position without compromising comfort when sitting still on the bike. The difference in recapturing the aerodynamic reference position during cycling after predefined deviations from the reference position at different intensities was analysed for 14 participants between three interventions, consisting of 1) vibrotactile feedback with a margin of error of 1.5% above the calibrated reference projected frontal area, 2) vibrotactile feedback with a margin of 3%, and 3) no feedback. The reference position is significantly more accurately achieved using vibrotactile feedback compared to no feedback (p < 0.001), but there is no significant difference between the 1.5% and 3% margin (p = 0.11) in terms of relative projected frontal area during cycling compared to the calibrated reference position (1.5% margin ?0.46 ± 1.76%, 3% margin ?0.01 ± 2.01%, no feedback 2.59 ± 3.29%). The results demonstrate that vibrotactile feedback can have an added value in assisting and correcting cyclists in recapturing their aerodynamic reference position.     

Continuous professional development and ECEC quality: Findings from a European systematic literature review

This article presents the findings of an analysis of the effects of CPD initiatives on the quality of the pedagogical practices of ECEC practitioners. It is part of a larger study commissioned by Eurofound and jointly conducted by VBJK, IOE and PPMI (Eurofound, 2015). In order to draw policy-relevant information that might support decision makers in designing effective ECEC policies in their countries, the study reviewed existing research evidence published on this topic not only in English, but also in all the languages currently in use in EU Member States. Therefore, it involved country experts from EU-28 Member States. The research question was framed by the political priorities identified by the Council Conclusions on Early Childhood Education and Care (EU Council, 2011). The systematic literature review methodology elaborated by the EPPI-Centre for informing evidence-based policies in the field of education and social sciences was adopted to review the evidence drawn from primary research studies cross-nationally. The study revealed that long-term CPD interventions integrated into practice, such as pedagogical guidance and coaching in reflection groups, proved to be effective not only in countries with a well-established system of ECEC provision and a high level of qualification requirements for the practitioners, but also in countries with poorly subsidised ECEC systems and low qualification requirements. CPD initiatives based on the active engagement of practitioners and on peer exchanges within a shared scientific framework, proved to be the most effective.     

Measurement of active drag during crawl arm stroke swimming

In order to measure active drag during front crawl swimming a system has been designed, built and tested. A tube (23 m long) with grips is fixed under the water surface and the swimmer crawls on this. At one end of the tube, a force transducer is attached to the wall of the swimming pool. It measures the momentary effective propulsive forces of the hands. During the measurements the subjects' legs are fixed together and supported by a buoy. After filtering and digitizing the electrical force signal, the mean propulsive force over one lane at constant speeds (ranging from about 1 to 2 m s-1) was calculated. The regression equation of the force on the speed turned out to be almost quadratic. At a mean speed of 1.55 m s-1 the mean force was 66.3 N. The accuracy of this force measured on one subject at different days was 4.1 N. The observed force, which is equal to the mean drag force, fits remarkably well with passive drag force values as well as with values calculated for propulsive forces during actual swimming reported in the literature. The use of the system does not interfere to any large extent with normal front crawl swimming; this conclusion is based on results of observations of film by skilled swim coaches. It was concluded that the system provides a good method of studying active drag and its relation to anthropometric variables and swimming technique.     

A meeting place for policy-makers and researchers: the Transatlantic Forum on Inclusive Early Years

While policy-makers and researchers in the field of early childhood education and care (ECEC) often seem to speak different languages, overwhelming research evidence on how quality ECEC can play a key role in alleviating the effects of disadvantage can be extremely relevant for policy-makers. In this article, we focus on how philanthropic foundations can facilitate the dialogue and bring together researchers, policy-makers and stakeholders on (particularly quality) issues in ECEC. In this article, we present a comprehensive advocacy project, designed by 13 philanthropic foundations on both sides of the Atlantic, under the leadership of the King Baudouin Foundation (KBF) (Belgium). This group of foundations wants to clarify, discuss and document some of the most relevant issues in ECEC at this point, with a focus on children from low-income and migrant families. Meetings have already taken place on accessibility, professionalisation and curriculum, parent involvement and evaluation. With the fifth forum – on integrated systems in ECEC – on its way, it is time for a short recap. Can meeting opportunities of this kind, for a limited group of policy-makers, successfully influence policy?     

Globalisation and localisation enmeshed—towards a framework for the development of guidance curriculum in Hong Kong

Hong Kong’s 150 years of colonisation by the British is a classic example of how globalisation comes into direct contact with a local Chinese culture and creates cultural hybridities. The paper presents a framework for developing a hybrid guidance curriculum, drawing together western traditions of developmental contextualism in guidance and Chinese traditions of Confucian humanism in moral education. The core of the framework is a hybrid self, integrating the individualist and the embedded self. The paper highlights the importance of culture and context in considering school guidance and the ‘fluid’ and dynamic nature of ‘glocalisation’ working towards integration.

Improving the effectiveness of peer feedback for learning

The present study examined the effectiveness of (a) peer feedback for learning, more specifically of certain characteristics of the content and style of the provided feedback, and (b) a particular instructional intervention to support the use of the feedback. A quasi-experimental repeated measures design was adopted. Writing assignments of 43 students of Grade 7 in secondary education showed that receiving ‘justified’ comments in feedback improves performance, but this effect diminishes for students with better pretest performance. Justification was superior to the accuracy of comments. The instructional intervention of asking assessees to reflect upon feedback after peer assessment did not increase learning gains significantly.     

Hydrogel discs for digital microfluidics

Hydrogels are networks of hydrophilic polymer chains that are swollen with water, and they are useful for a wide range of applications because they provide stable niches for immobilizing proteins and cells. We report here the marriage of hydrogels with digital microfluidic devices. Until recently, digital microfluidics, a fluid handling technique in which discrete droplets are manipulated electromechanically on the surface of an array of electrodes, has been used only for homogeneous systems involving liquid reagents. Here, we demonstrate for the first time that the cylindrical hydrogel discs can be incorporated into digital microfluidic systems and that these discs can be systematically addressed by droplets of reagents. Droplet movement is observed to be unimpeded by interaction with the gel discs, and gel discs remain stationary when droplets pass through them. Analyte transport into gel discs is observed to be identical to diffusion in cases in which droplets are incubated with gels passively, but transport is enhanced when droplets are continually actuated through the gels. The system is useful for generating integrated enzymatic microreactors and for three-dimensional cell culture. This paper demonstrates a new combination of techniques for lab-on-a-chip systems which we propose will be useful for a wide range of applications.
