The composition of the editorial boards of leading general paediatric journals was assessed. The board members' country of current affiliation was classified according to the Human Development Index. The results showed that only a very small number of the board members are based in the developing world.

As a scientific discipline matures, its theoretical underpinnings tend to consolidate around a few general laws that explain a wide range of phenomena, and from which can be derived further testable predictions. It is one of the goals of science to uncover the general principles that produce recurring patterns in nature. Although this has happened in many areas of physics and chemistry, ecology...

Many recent studies using healthy adults document enhancements in perception and cognition from playing commercial action videogames (AVGs). Playing action games (e.g., Call of Duty, Medal of Honor) is associated with improved bottom-up lower-level information processing skills like visual-perceptual and attentional processes. One proposal states a general improvement in the ability to interpre...

A fundamental assumption in cost accounting is that the relation between costs and volume is symmetric for volume increases and decreases. In this study, we investigate whether costs are “sticky”—that is, whether costs increase more when activity rises than they decrease when activity falls by an equivalent amount. We find, for 7,629 firms over 20 years, that selling, general, and administrativ...

Indium acetate was analyzed using x-ray photoelectron spectroscopy. The specimen is a powder purchased from Sigma Aldrich. sample fixed to stainless-steel holder with copper 3MTM double-sided adhesive tape. Survey spectra, In 3d, O 1s, C 3p, MNN, and Cl 2p core levels spectra were acquired. Results showed how the elements in structure of indium are related.

“All models are wrong but some are useful" [1]. We address the problem of identifying which diagnosis models are more useful than others. Models are critical to diagnostics inference, yet little work exists to be able to compare models. We define the role of models in diagnostics inference, propose metrics for models, and apply these metrics to a tank benchmark system. Given the many approaches...

An analysis of the climate parametrization scheme adopted by conventional forest gap models revealed that most models assume a constant climate and are difficult to calibrate consistently. Tree growth showed unrealistically sensitive threshold effects along ecological gradients of temperature and precipitation. A new parametrization was compared with its predecessors in terms of the model's cap...
