Boxing Technique
No full textTactics, awareness and decision-making are very important in boxing when sparring or competing but the focus of the session Richard reflects on in this chapter was purely technical and aimed at learners with no, or little, knowledge or experience of this sport. It focuses on teaching the jab and cross as two basic punches in boxing to undergraduate Sport Coaching students in New Zealand as a way of showing them how to use PPed for coaching technique as an alternative to coach-centred, direct instruction. The chapter also identifies how Richard has gradually developed his teaching of this class by critically reflecting on student experience and, considering to what extent he is addressing the features of PPed and how his teaching is influenced by context. He developed the session in New Zealand but ran a workshop on boxing technique at the 2018 Ohio Global Coaching Symposium that he drew on to improve the session but while recognising some limitations due to the different cultures and situations
Beach sprint starts
No full textThis chapter recounts my experiences of working as an age group manager in a ‘nippers’ program at a surf lifesaving club in Sydney, Australia. Nippers programs focus on educating children from five years of age to fourteen about the environment of the beach and ocean where so many Australians spend their time in summer, encouraging healthy active lifestyles, and introducing them to the culture of surf life-saving. As readers outside Australia and New Zealand may know little about the function and culture of surf lifesaving in Australia, I include a brief explanation of surf lifesaving in Australia and the aims of nippers programs to provide a context for my discussion of a Positive Pedagogy for sport coaching approach I adopted to help young nippers learn and improve their beach sprint start technique. The session I recount was very early in the season and before any interclub competitions
An outline of Positive Pedagogy for sport coaching
No full textIn this chapter we provide an overview of Positive Pedagogy for sport coaching for all sports. It begins with its development from the features of game-based approaches (GBA) to then move on to the appropriation of Antonvosky’s sense of coherence (SoC) model and the use of Positive Psychology to enhance its inherently positive nature

Influence of a PPed university course on coaches’ practice on New Zealand.
No full textGrowth in university sport coaching programs offers a promising means of spreading the uptake of GBA (game-based approaches) due to the greater opportunity they offer to initiate change in coaching. Although studies have been conducted on higher education coach education with some on GBA, none have looked at the efficacy of the HE pedagogy used. This chapter draws on a study that inquired into the influence of a course on Positive Pedagogy for sport coaching taught in a in a New Zealand university. It focuses on six on final year students for a six moth period following completion of the course and how they adapted PPed to their coaching needs, opportunities and limitations as coaches outside the university. It provides useful insights into how young coaches taking up PPed meet the challenges involved

Surface plasmon polariton modification in top-emitting organic light-emitting diodes for enhanced light outcoupling
No full textWe report on the enhanced light outcoupling efficiency of monochrome top-emitting organic light-emitting diodes (OLEDs). These OLEDs incorporate a hole transport layer (HTL) material with a substantially lower refractive index (∼ 1:5) than the emitter material or the standard HTL material (∼ 1:8) of a reference device. This low-index HTL is situated between the opaque bottom metal contact (anode) and the active emission layer. Compared to an HTL with common refractive index, the dispersion relation of the surface plasmon polariton (SPP) mode from the opaque metal contact is shifted to smaller in-plane wavenumbers. This shift enhances the outcoupling efficiency as it reduces the total dissipated power of the emitter. Furthermore, the excitation of the coupled SPPs at the thin transparent metal top contact (cathode) is avoided by using an ultrathin top electrode. Hence, the coupling of the electroluminescence from the emitter molecules to all non-radiative evanescent modes, with respect to the emitter material, is reduced by at least a factor of two, additionally increasing the outcoupling efficiency. Furthermore, for sufficiently high refractive index contrast the shift of the SPP at the anode/organic interface can lead to in-plane wavenumbers smaller than the wavenumber within the organic emitter layer and outcoupling of all excited modes by high index light extraction structures, e.g. microlens, seems feasible. In accordance to optical simulations, the external quantum efficiency is enhanced by about 20% for monochrome green emitting OLEDs with low refractive index HTL compared to a reference sample
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Three-dimensional measurements of heavy and light particle dispersion in shear turbulence
No full textWe present new experimental data concerning the statistics of heavy and light particles dispersed at low concentrations in a homogeneous turbulent shear flow. Information on both the spatial distribution and on the relative velocity of the dispersed phases is obtained by accurate three-dimensional optical measurements, and will allow to comparatively discuss the issues of turbulent clustering and small scale anisotropy by analyzing the scale- and angular dependence of suitable particle observables computed in the two cases
"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
No full textBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
