To determine whether youth athletes with an "average" (regional), "high" (sub-elite), and "very high" (elite) level of performance differ with respect to their self-assessed tactical skills, 191 youth field hockey players (mean age 15.5 years, s = 1.6) completed the Tactical Skills Inventory for Sports (TACSIS) with scales for declarative ("knowing what to do") and procedural ("doing it") knowl...

the aim of this study was to describe and assess general anthropometric measurements and somatotypes of elite male players of iran adult handball national team and to compare these measurements with those of european elite players in different positions. 19 elite handball players of iran national handball team including goalkeepers (n=4), wing (n=4), center backs (n=2), pivots (n=2) and backs (...

Several species of Phytophthora cause crown and root rot diseases of herbaceous and woody plants. Crown and root rot of pistachio trees cause significant damages in infected orchards. The effect of foliar application with Elite (fosetyl-Al) in 2 and 2.5 g/l was evaluated in greenhouse experiments. The frequency of mortality, fresh and dry weight of roots and shoots, height, intensity of crown r...

The aim of the present study was to compare the anthropometry and somatotype of pre-adolescent soccer players of a wide range of levels and ages, and boys of the general population, in order to defi ne the most relevant anthropometric characteristics related to success and promotion to youth soccer elite levels.

Darwin-inspired population thinking suggests approaching culture as a population of items of different types, whose relative frequencies may change over time. Three nested subtypes of populational models can be distinguished: evolutionary, selectional and replicative. Substantial progress has been made in the study of cultural evolution by modelling it within the selectional frame. This progres...

Models of cultural evolution study how the distribution of cultural traits changes over time. The dynamics of cultural evolution strongly depends on the way these traits are transmitted between individuals by social learning. Two prominent forms of social learning are payoff-based learning (imitating others that have higher payoffs) and conformist learning (imitating locally common behaviours)....

The purpose of this study was to profile elite and recreational SUP with respect to anthropometric, physiological and musculoskeletal measurements. A total of 30 SUP participants (15 recreational, 15 elite) and 15 sedentary controls participated in this...

We build a dynamic political economy model with a two-class society: workers and the elite. In the model, the formation of the elite, the rate of innovation and …scal policy are endogenous. We focus on the con‡ict within the elite over two fundamental engines of economic growth: innovation and public investment. The model creates a mapping between institutions and economic outcomes which is con...
