Using an adaptation programme to introduce children to the early years of schooling in Slovakia

The article presents a new adaptation programme entitled ‘With a smile to school’ for pupils of the first year at primary schools. The adaptation programme comprises several methods and measures which are focused on the regulation of pupils’ adaptation process. The efficiency and effectiveness of the adaptation programme were verified through an experiment at selected primary schools in Slovakia in the school year 2016/2017. Based on the experiment results, a proposal for implementation of the adaptation programme to school practice was drawn up. The experiment results were evaluated by means of selected statistical methods.

Orphan Works at Theatre Library and Information Centres: Assessing Librarians' Perceptions and Management in Spain

Currently, libraries and other information services are facing new professional challenges in relation to digitization policies and orphan works after the publication of European Directive 2012/28/EU on certain permitted uses of orphan works and Spanish Royal Decree 224/2016. This paper aims to analyse how Spanish library and information centres specialising in theatre and performing arts meet users' textual and non-textual information needs, by respecting copyright issues and being involved in a dynamic and digital environment. For this purpose, an online questionnaire, which was used as a methodological tool, was sent to library directors in February 2018. At the same time, some research questions based on orphan works and digitisation approaches are discussed in the paper, specifically in reference to graphic and audiovisual materials.     

Irreplaceable ISSN: From 2007 to the Future

International Organization for Standardization (ISO) standard 3297 governs the assignment of International Standard Serial Numbers (ISSNs) for continuing resources worldwide. It is subject to systematic review every five years and, in 2017, an ISO Working Group was set up to review the standard. This working group took the decision to survey the views of stakeholders including publishers, libraries, and others. This article reports on the global survey that was undertaken, describing the questions and answers about which the committee sought opinions. It also sought details on the respondents to provide context. The replies are summarised in chart form with conclusions and an appraisal of the key issues, which suggest that whilst respondents are supportive of expanding the ways in which the ISSN is deployed, they are less convinced of the need for more ISSNs for any given title. They are split on the need for the structure of the ISSN to be revised but there is strong support for the notion of a “Family ISSN” that would describe resources that are linked through, for example, title changes or geography or language. The article notes the next steps to be taken.

Effects of treadmill running and fatigue on impact acceleration in distance running

The effects of treadmill running on impact acceleration were examined together with the interaction between running surface and runner's fatigue state. Twenty recreational runners (11 men and 9 women) ran overground and on a treadmill (at 4.0 m/s) before and after a fatigue protocol consisting of a 30-minute run at 85% of individual maximal aerobic speed. Impact accelerations were analysed using two lightweight capacitive uniaxial accelerometers. A two-way repeated-measure analysis of variance showed that, in the pre-fatigue condition, the treadmill running decreased head and tibial peak impact accelerations and impact rates (the rate of change of acceleration), but no significant difference was observed between the two surfaces in shock attenuation. There was no significant difference in acceleration parameters between the two surfaces in the post-fatigue condition. There was a significant interaction between surface (treadmill and overground) and fatigue state (pre-fatigue and post-fatigue). In particular, fatigue when running overground decreased impact acceleration severity, but it had no such effect when running on the treadmill. The effects of treadmill running and the interaction need to be taken into account when interpreting the results of studies that use a treadmill in their experimental protocols, and when prescribing physical exercise.     

The effect of normal load force and roughness on the dynamic traction developed at the shoe–surface interface in tennis

During tennis-specific movements, such as accelerating and side stepping, the dynamic traction provided by the shoe–surface combination plays an important role in the injury risk and performance of the player. Acrylic hard court tennis surfaces have been reported to have increased injury occurrence, partly caused by increased traction that developed at the shoe–surface interface. Often mechanical test methods used for the testing and categorisation of playing surfaces do not tend to simulate loads occurring during participation on the surface, and thus are unlikely to predict the human response to the surface. A traction testing device, discussed in this paper, has been used to mechanically measure the dynamic traction force between the shoe and the surface under a range of normal loading conditions that are relevant to real-life play. Acrylic hard court tennis surfaces generally have a rough surface topography, due to their sand and acrylic paint mixed top coating. Surface micro-roughness will influence the friction mechanisms present during viscoelastic contacts, as found in footwear–surface interactions. This paper aims to further understand the influence micro-roughness and normal force has on the dynamic traction that develops at the shoe–surface interface on acrylic hard court tennis surfaces. The micro-roughness and traction of a controlled set of acrylic hard court tennis surfaces have been measured. The relationships between micro-roughness, normal force, and traction force are discussed.     

Testing method for objective evaluation of cross-country ski poles

The aim of the study was to develop an objective classification method for cross-country ski poles. A test device was designed to expose different pole models to maximal loading and impact tests. A load cell measured the axial forces in the pole shafts, and a laser distance meter measured shaft deflection when a load was applied via the wrist strap. In the loading tests, each shaft reached a plateau where no more force could be transferred. This maximal force transfer (MFT) value was a characteristic measure for flexural rigidity and thereby also strength. The developed test method enables a loading that is more similar to real-life skiing than a standard three-point bending test. Results show that the introduction of shaft indices for buckling strength is beneficial for comparison purposes. The MFT is a relevant parameter used in the characterization of poles.     

The effects of surface traction characteristics on frictional demand and kinematics in tennis

The interaction between footwear and surfaces influences the forces experienced by tennis players. The purpose of this study was to investigate traction demand and kinematic adaptation during tennis-specific movements with changes in traction characteristics of surfaces. We hypothesised that players would increase the utilised coefficient of friction (horizontal to vertical ground reaction force ratio) when the shoe surface combination had a high coefficient of friction and flex their knee after contact to facilitate braking. Eight participants performed two separate movements, side jump out of stance and running forehand. Ground reaction force was measured and three-dimensional kinematic data were recorded. Clay surface and cushioned acrylic hard court (low vs. high shoe–surface friction) were used. The peak utilised coefficient of friction was greater on clay than the hard court. The knee was less flexed at impact on clay ( ? 5.6 ± 10.2°) and at peak flexion ( ? 13.1 ± 12.0°) during the running forehand. Our results indicate that tennis players adapt the level of utilised friction according to the characteristics of the surface, and this adaptation favours sliding on the low friction surface. Less knee flexion facilitates sliding on clay, whereas greater knee flexion contributes to braking on the hard court.
