The United States and Canadian governments are mounting a defence against Russian invasion. No, the clock has not been turned back. These invaders are Asian gypsy months, foliage-chomping insects that can cause billions of dollars in damage. Experts believe they entered North America from Russia last year in egg masses attached to grain vessels. The larger Asian gypsy moth is more voracious feeder than the common North American strain and can feed on pacific northwest tree species. Unlike the flightless North American female, an Asian female can fly 20 miles between mating and egg -laying. The United States Health Inspection Service is barring from west coast ports ships found carrying egg masses. The Tacoma and Portland areas, as well as Vancouver. British Columbia has been sprayed with a bio-pesticide.
Most investigators concur that certain facial expressions suggest the same emotions all people. Moreover, people in diverse cultures recognise the emotions manifested by the facial expressions. In classic research Paul Ekman took photographs of people exhibiting the emotions of anger, disgust, fear, happiness and sadness. He then asked people around the world to indicate what emotions were being depicted in them. Those queried ranged from European college students to members of the Fore, a tribe that dwells in the New Guinea highlands. All groups, including the Fore who had almost no contact with Western culture, agreed on the portrayed emotions. The Fore also displayed familiar facial expressions when asked how they would respond if they were the characters in the stories that called for basic emotional response. Ekman and his colleagues more recently obtained similar results in a study of ten cultures in which participants were permitted to report that multiple emotions were shown by facial expressions. The participants generally agreed on which two emotions were being shown and on which emotion was more intense.
What was the group of people on whom subsequent researches were conducted to obtain similar results as earlier?
