This study reports the findings of Granger causality tests on the relationship between FDI and pollution across 112 countries over 15-28 years. Our results uncover alternative causality relationships between the two variables depending on a host country's level of development. Copyright © 2005 John Wiley & Sons, Ltd.

This paper reports regression results identifying the variables influencing a country's performance in international soccer games. The results reveal that economic, demographic, cultural and climatic factors are important. In particular, inverted U-shape relationships are identified with respect to temperature and per-capita wealth. We also find a significant interaction between Latin cultural origin and population size, while both variables are individually insignificant. Explanations for our results are offered.

The purpose of this study was to correlate subjective sleep characteristics based on questionnaire response, and objective sleep EEG features based on polysomnography, in 52 patients with major depressive disorders (MDD) and 49 healthy controls. With the exception of the number of awakenings, subjective and objective sleep measures were strongly correlated in both groups. Patients and controls were able to accurately judge time in bed, total sleep time and sleep latency. However, sleep quality, depth, and how rested participants felt upon awakening were not strongly correlated with objective sleep characteristics, particularly in those with MDD The findings suggest that estimates such as total sleep time and sleep latency, obtained from questionnaire data, bear a strong resemblance to objective polysomnographic characteristics in both those with MDD and healthy controls. Patients with MDD do not show sleep‐state misperceptions although depressed women are more accurate in estimating sleep characteristics than depressed men.

Circadian rhythms appeared much more rapidly in this infant than previously reported; their rapid appearance was probably facilitated by maximal exposure to sunlight, and regular social cues. These lighting conditions replicate universal infant experience prior to the invention of artificial light.
