The purpose of this study was to test a motivational model of the coach-athlete relationship, based on self-determination theory and on the hierarchical model of intrinsic and extrinsic motivation. The sample comprised of 608 athletes (ages of 12-17 years) completed the following measures: interest in athlete's input, praise for autonomous behavior, perceived autonomy, intrinsic motivation, and...

Define a mixture with volume V containing a certain amount of clay (Vc) and sand (Vs), i.e. V = Vc + Vs. The intrinsic porosity of the clay is φc, defined as the ratio of pore volume in the clay V c p to the volume of clay, i.e. φc = V c p /Vc, and the intrinsic porosity of sand is φs = V s p /Vs. The surface areas of the pores in the clay and in the sand are noted S p and S s p respectively. S...

Decades of scientific research shows that intrinsic motivation (IM) is a powerful "engine" of learning and positive development. This chapter synthesizes the research, first showing how the psychological state of IM is associated not only with enhanced engagement and perseverance in an activity, but also with greater use of meta-cognitive strategies and deeper processing of information. These f...

The spline finite strip method (S.F.S.M.) for buckling analysis of plates and plate assemblies subjected to longitudinal compression and bending, transverse compression as well as shear is described. The method allows for the boundary conditions. Local buckling coefficients of plates with different boundary conditions under compression, bending and shear are calculated. Convergence studies with...

Interband cascade lasers are semiconductor emitting in the mid-infrared domain but relying on interband transitions, contrary to their intersubband counterparts, quantum lasers. Our experimental study of relative intensity noise a multi-mode laser at 4.1 ?m shows that room-temperature structure exhibits relaxation frequency GHz range. We demonstrate that, far above threshold current, increases ...

This paper presents an extensive evaluation of five different alignments and investigates their impact on the corresponding MT system output. We introduce new measures for intrinsic evaluations and examine the distribution of phrases and untranslated words during decoding to identify which characteristics of different alignments affect translation. We show that precision-oriented alignments yie...

Given a contraction A on Hilbert space $${\mathcal {H}}$$ , an operator T is said to be A-invariant if $$\langle Tx,x\rangle =\langle TAx,Ax\rangle $$ for every $$x\in {\mathcal such that $$\Vert Ax\Vert =\Vert x\Vert . In the special case in which both defect indices of are equal 1, we show compression unbounded linear transformation commutes with minimal unitary dilation A. This result was pr...

The necessity for decrease in consumption of conventional fuel, related energy and to promote the use of renewable sources such as biofuels, demands for the effective evaluation of the performance of engines based on laws of thermodynamics. Energy, exergy, entropy generation, mean gas temperature and exhaust gas temperature analysis of CI engine using diesel and karanja methyl ester blends at d...
