Operations control is one of the most important areas for an airline company. Through operations control mechanisms an airline company monitors all the flights checking if they follow the schedule that was previously defined by other areas of the company. Unfortunately, some problems may arise during this stage (Clausen et al., 2005). Those problems can be related with crewmembers, aircrafts an...

OBJECTIVE To find out the effect of prenatal exposure to low lead from cosmetics on gestational age, premature rupture of the membrane and birth weight. METHODS The study was carried out in the mountainous Aseer region, Southwest of Saudi Arabia where the air is thought to be clean and free of lead pollution due to the absence of petroleum smelting and other heavy industries. The region is fa...

Legged robots are versatile machines that can outperform wheeled robots on rough terrain (Raibert, 1986), for instance in exploration or rescue missions. Their versatility is, however, tempered by their mechanical and control complexity, which makes them prone to mechanical damages and difficult to control robustly (Raibert, 1986; Bongard et al., 2006; Koos et al., 2013a). A promising way to co...

Dear reader, In the last two issues we have turned to adjacent fields and looked at anthropology and economics. In this issue we zoom in on geography. From this glance we suggest that at least these three disciplines are getting increasingly " sociological ". Sociological ideas, theories, concepts, and ways of reasoning are being used also outside of sociology. We also argue that sociologists c...

Dionaea is a highly specialized carnivorous plant species with a unique mechanism for insect capture. The leaf is converted into an osmotically driven trap that closes when an insect triggers sensory trichomes. This study investigates the significance of insect capture for growth of Dionaea at different successional stages after a fire, under conditions where the prey is highly variable in its ...

When I think of theword niche, phrases such as a “specialized place” or a “distinct segment” come to mind. When it was time to identify the theme for the 2014 Active Living Research (ALR) Conference, we thought about how some people consider the field of active living a niche area. Because of this, it is not entirely surprisingly that around the world, communities still lack sidewalks, pedestri...

The effects of imagery practice on motor skill acquisition have been examined for over 50 years (Sackett, 1935) under many labels. Mental practice (Corbin, 1967), mental rehearsal (Y amamoto & Inomata, 1982), mental training (Ulich, 1967), and visuo-motor behavior rehearsal (Noel, 1980) have all been employed to describe basically the same process. Equally varied have been the motor tasks utili...

Thomas Friedman and Jeffrey Sachs—articulate, learned globetrotting pundits— would seem an unlikely duo to hijack the development debate. Yet, through their best-selling books—Friedman’s The World Is Flat and Sachs’s The End of Poverty—their prominent exposure in the U.S. media, and endorsements by celebrities like Bono, the superstar lead singer of the rock group U2, they have done precisely t...
