Varying-coefficient models with categorical effect modifiers are considered within the framework of generalized linear models. We distinguish between nominal and ordinal effect modifiers, and propose adequate Lasso-type regularization techniques that allow for (1) selection of relevant covariates, and (2) identification of coefficient functions that are actually varying with the level of a pote...

Adolescence is often viewed as a critical period for selection in youth soccer. The present study compared the characteristics of regionally selected and non-selected under-14 players (U-14) as a group and by position. Players were classified as local (n=69) and regional (n=45). Weight, height, skinfolds, functional capacities, soccer skills and goal orientation were measured and skeletal age w...

What is attention? On one influential position, attention constitutively the selection of some stimulus for coupling with a response. Wayne Wu has proposed master argument this position that relies on claim cognitive science commits to an empirical sufficient condition (ESC), according which, if subject S perceptually selects (or response-couples) X guide performance experimental task T, she th...

Attentional selectivity in touch is modulated by the position of the body in external space. For instance, during endogenous attention tasks in which tactile stimuli are presented to the hands, the effect of attention is reduced when the hands are placed far apart than when they are close together and when the hands are crossed as compared to when they are placed in their anatomical position. T...

the main objective of this study was to understand of genetic association between quantitative and qualitative traits and also to quantify effects of selection for one trait on others in safflower. the study took place in the experimental field of the faculty of agriculture, isfahan university of technology, isfahan, iran, in the 2001 and 2002. to find the best variable for selection to improve...
