Max Ringelmann
Maximilien Ringelmann (10 December 1861, Paris – 2 May 1931, Paris) was a French professor of agricultural engineering and agronomic engineer who was involved in the scientific testing and development of agricultural machinery. Ringelmann's interests were wide-ranging: he developed the Ringelmann scale which is still used to measure smoke. He also discovered the Ringelmann effect in social psychology, viz, that when working in groups, individuals slacken. Education After graduating from the public schools of Paris, Ringelmann studied at the Institute National Agronomique (National Institute of Agronomy), where he was an outstanding student. He also attended Hervé Mangon’s evening course in rural engineering at the Conservatoire National des Arts et Métiers (National Conservatory of Arts and Crafts). (Charles-François Hervé Mangon (1821–1888) had been trained as a civil engineer, but his interest shifted to agriculture, where he studied irrigation, drainage, fertiliz ...

Paris
Paris () is the capital and most populous city of France, with an estimated population of 2,165,423 residents in 2019 in an area of more than 105 km² (41 sq mi), making it the 30th most densely populated city in the world in 2020. Since the 17th century, Paris has been one of the world's major centres of finance, diplomacy, commerce, fashion, gastronomy, and science. For its leading role in the arts and sciences, as well as its very early system of street lighting, in the 19th century it became known as "the City of Light". Like London, prior to the Second World War, it was also sometimes called the capital of the world. The City of Paris is the centre of the Île-de-France region, or Paris Region, with an estimated population of 12,262,544 in 2019, or about 19% of the population of France, making the region France's primate city. The Paris Region had a GDP of €739 billion ($743 billion) in 2019, which is the highest in Europe. According to the Economist Intelli ...

Académie D'Agriculture
The Académie d'agriculture de France is a voluntary association aiming to contribute to the evolution of agriculture and rural life in the scientific, technical, economic, judicial, legal, social and cultural fields. It is the successor to the société d'agriculture de la Généralité de Paris, founded in 1761 by Louis XV, and has functioned in its present form since a decree of 1878 which recognised it as a public utility. It has 120 titular members and 180 French corresponding members, as well as 60 foreign members. Its bureau is its executive organ and is made up of 6 members, with a president elected for a year and a life secretary elected by his or her peers and named by decree of the French President. It awards annual prizes and medals for contributions to the advancement of agricultural knowledge. It is based in Paris in a hôtel particulier An ''hôtel particulier'' () is a grand townhouse, comparable to the British townhouse or mansion. Whereas an ordinary ''maison ...

Social Psychologists
Social organisms, including human(s), live collectively in interacting populations. This interaction is considered social whether they are aware of it or not, and whether the exchange is voluntary or not. Etymology The word "social" derives from the Latin word ''socii'' ("allies"). It is particularly derived from the Italian ''Socii'' states, historical allies of the Roman Republic (although they rebelled against Rome in the Social War of 91–87 BC). Social theorists In the view of Karl MarxMorrison, Ken. ''Marx, Durkheim, Weber. Formations of modern social thought'', human beings are intrinsically, necessarily and by definition social beings who, beyond being "gregarious creatures", cannot survive and meet their needs other than through social co-operation and association. Their social characteristics are therefore to a large extent an objectively given fact, stamped on them from birth and affirmed by socialization processes; and, according to Marx, in producing and reproducin ...

Social Psychology
Social psychology is the scientific study of how thoughts, feelings, and behaviors are influenced by the real or imagined presence of other people or by social norms. Social psychologists typically explain human behavior as a result of the relationship between mental states and social situations, studying the social conditions under which thoughts, feelings, and behaviors occur, and how these variables influence social interactions. History Although issues in social psychology have been discussed in philosophy for much of human history, the scientific discipline of social psychology formally began in the late 19th to early 20th century. 19th century In the 19th century, social psychology began to emerge from the larger field of psychology. At the time, many psychologists were concerned with developing concrete explanations for the different aspects of human nature. They attempted to discover concrete cause-and-effect relationships that explained social interactions. In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Draught Animals
A working animal is an animal, usually domesticated, that is kept by humans and trained to perform tasks instead of being slaughtered to harvest animal products. Some are used for their physical strength (e.g. oxen and draft horses) or for transportation (e.g. riding horses and camels), while others are service animals trained to execute certain specialized tasks (e.g. hunting and guide dogs, messenger pigeons and fishing cormorants). They may also be used for milking or herding. Some, at the end of their working lives, may also be used for meat or other products such as leather. The history of working animals may predate agriculture, with dogs used by our hunter-gatherer ancestors. Around the world, millions of animals work in relationship with their owners. Domesticated species are often bred for different uses and conditions, especially horses and working dogs. Working animals are usually raised on farms, though some are still captured from the wild, such as dolphins a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Social Loafing
In social psychology, social loafing is the phenomenon of a person exerting less effort to achieve a goal when they work in a group than when working alone. It is seen as one of the main reasons groups are sometimes less productive than the combined performance of their members working as individuals. Research on social loafing began with rope pulling experiments by Ringelmann, who found that members of a group tended to exert less effort in pulling a rope than did individuals alone. In more recent research, studies involving modern technology, such as online and distributed groups, have also shown clear evidence of social loafing. Many of the causes of social loafing stem from individual members' feeling their individual effort will not matter to the group. Max Ringelman, a French professor of agricultural engineering, demonstrated in the 1890s the concept of social loafing. Ringelman, who was also considered one of the founders of social psychology, made people pull on ropes bot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

North Africa
North Africa, or Northern Africa is a region encompassing the northern portion of the African continent. There is no singularly accepted scope for the region, and it is sometimes defined as stretching from the Atlantic shores of Mauritania in the west, to Egypt's Suez Canal. Varying sources limit it to the countries of Algeria, Libya, Morocco, and Tunisia, a region that was known by the French during colonial times as "''Afrique du Nord''" and is known by Arabs as the Maghreb ("West", ''The western part of Arab World''). The United Nations definition includes Morocco, Algeria, Tunisia, Libya, Egypt, Sudan, and the Western Sahara, the territory disputed between Morocco and the Sahrawi Republic. The African Union definition includes the Western Sahara and Mauritania but not Sudan. When used in the term Middle East and North Africa (MENA), it often refers only to the countries of the Maghreb. North Africa includes the Spanish cities of Ceuta and Melilla, and plazas de s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
French Colony
The French colonial empire () comprised the overseas colonies, protectorates and mandate territories that came under French rule from the 16th century onward. A distinction is generally made between the "First French Colonial Empire", that existed until 1814, by which time most of it had been lost or sold, and the "Second French Colonial Empire", which began with the conquest of Algiers in 1830. At its apex between the two world wars, the second French colonial empire was the second-largest colonial empire in the world behind the British Empire. France began to establish colonies in North America, the Caribbean and India in the 17th century but lost most of its possessions following its defeat in the Seven Years' War. The North American possessions were lost to Britain and Spain but the latter returned Louisiana (New France) to France in 1800. The territory was then sold to the United States in 1803. France rebuilt a new empire mostly after 1850, concentrating chiefly in Africa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North America
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Plate, North American Tectonic Plate, Greenland is included as a part of North America geographically. North America covers an area of about , about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the list of continents and continental subregions by population, fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in List of sovereign states and dependent territories in North America, 23 independent states, or about 7.5% of the world's population.
