Un article de Wikipédia, l'encyclopédie libre.
L' homme de la rue est un terme servant à désigner une hypothétique personne de profil moyen représentant la société dans laquelle elle vit. Le terme vient du latin « quidam » qui signifie initialement « simple mortel » par opposition aux Dieux et aux hommes de pouvoirs. De là est venu l' effet Quidamus , lorsqu'un simple mortel bouleversait consciemment ou non (ne serait-ce que par sa simple présence au mauvais/bon endroit, au mauvais/bon moment) les plans des Dieux ou des puissants, en bien ou en mal. Le terme quidamus a été repris en sociologie et philosophie, le terme quidam , lui, est plus employé dans les milieux de l'information. Surtout mentionnée dans les articles de journaux, cette personne n'a aucune définition précise, encore moins scientifique. Curieusement l'homme de la rue n'a pas de féminin. Usage dans les pays francophones [ modifier ] L' homme de la rue est désigné ou précisé de différentes façons selon les pays :
Scientists call for action to tackle CO2 levels. 11 May 2013Last updated at 03:52 ET The last time CO2 was regularly above 400ppm was three to five million years ago Scientists are calling on world leaders to take action on climate change after carbon dioxide levels in the atmosphere broke through a symbolic threshold.
Daily CO2 readings at a US government agency lab on Hawaii have topped 400 parts per million for the first time. Sir Brian Hoskins, the head of climate change at the UK-based Royal Society, said the figure should "jolt governments into action". China and the US have made a commitment to co-operate on clean technology. But BBC environment analyst Roger Harrabin said the EU was backing off the issue, and cheap fossil fuels looked attractive to industries. The laboratory, which sits on the Mauna Loa volcano, feeds its numbers into a continuous record of the concentration of the gas stretching back to 1958. 'Sense of urgency' Human sources come principally from the burning of fossil fuels such as coal, oil and gas.
Who funded Darwin's research? In 1831 Robert FitzRoy, the new commander of the HMS Beagle, a Cherokee class 10-gun brig-sloop of the Royal Navy (so, military, state owned) used for geographic and scientific/military coastal studies, was almost ready for the second expedition of his ship.
He feared loneliness and to be prone to suicide, because he had previous episodes in his family, and the former commander of the HMS Beagle (Capt. Pringle Strokes) committed suicide during the first expedition. He had no commanding officer nor second captain and no one on board of his social or cultural level. He tried to convince his friend Harry Chester with the idea of Harry accompanying him, but this came to nothing. Consequently, upon his return home, Darwin received letters from Henslow saying "I assure you I think you are the very man they are in search of" for the position "more as a companion than a mere collector", and from Peacock who said the post was at his "absolute disposal".
French Double Negatives - La double négation. Grammarians insist that two negatives make a positive.
While this may be true in English, in French two negatives usually make a stronger negative. Double negation is very common in French, particularly informal French. However, there are some rules and regulations when using double negatives in French. Double negation with ne... pas When ne... pas is used in a double negative with rien , it negates rien so that the meaning is "not nothing": Ce n'est pas rien.
Ne... pas cannot be used with aucun , jamais , or personne . Wrong: Je n'ai pas aucun ami. Wrong: Je ne veux pas jamais grandir. Wrong: Je n'ai pas vu personne. Double negation with ne... jamais and ne... plus. Transportation: They Say We Had a Revolution (Part 2) Fold a piece of paper so that it has three columns.
At the top of the first column, write "Invention. " At the top of the second and third columns, write "Innovation" and "Infrastructure," respectively. Find at least five examples of each as you complete the lesson. Invention is the creation of a new object or process. One of the technological inventions that most significantly contributed to the Transportation Revolution was the steam engine.
Innovations change how people use preexisting ideas and products. Infrastructure is the set of interconnected elements that support the use of inventions and innovations. You will explore how the changes in transportation helped transform the U.S. and its economy during the 20th century. As the 19th century came to a close, most Americans lived in rural areas but had begun moving to the cities in record numbers.
