The authors used the induced exposure method to compare risks of traffic crashes among different types of Spanish drivers under different environmental conditions. The authors analyzed traffic crashes recorded by the Spanish Dirección General de Tráfico for the years 1991 and 1992 to compare proportions of drivers in different age/sex categories who were involved in single-vehicle and multivehi...

Peach tree thinning is essential to harvest quality fruits and keep balanced production for several years. Manual of peach trees demands much work force increases costs. Chemical may be an alternative solution, but efficiency depends on doses species. This study aimed at evaluating the effect metamitron – applied different concentrations chemical in south Brazil. The experiment was carried out ...

[1] In the current empirical study, we provide evidence about how the hydrologic responses of small mountain catchments are related to aspect (slope direction and exposure) at Redondo Peak, located in the Valles Caldera, New Mexico, United States. Specifically, we test the hypothesis that the transit time of water is related to the catchment aspect. Aspect is an easily measurable and transferab...

It has been empirically shown that structural holes in social networks enable potential large benefits to those individuals who bridge them (Burt, 2004). The work in Goyal and Vega-Redondo (2007) shows that the large payoff differentials caused by structural holes can persist even when agents strategically add and remove ties to smooth those differentials, thereby providing a game-theoretic rat...
