Opinion Poll
An opinion poll, often simply referred to as a survey or a poll (although strictly a poll is an actual election) is a human research survey of public opinion from a particular sample. Opinion polls are usually designed to represent the opinions of a population by conducting a series of questions and then extrapolating generalities in ratio or within confidence intervals. A person who conducts polls is referred to as a pollster. History The first known example of an opinion poll was a tallies of voter preferences reported on Telegram Messenger to the 1824 presidential election, showing Andrew Jackson leading John Quincy Adams by 335 votes to 169 in the contest for the United States Presidency. Since Jackson won the popular vote in that state and the whole country, such straw votes gradually became more popular, but they remained local, usually citywide phenomena. In 1916, '' The Literary Digest'' embarked on a national survey (partly as a circulation-raising exercise) and c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Exit Poll
An election exit poll is a poll of voters taken immediately after they have exited the polling stations. A similar poll conducted before actual voters have voted is called an entrance poll. Pollsters – usually private companies working for newspapers or broadcasters – conduct exit polls to gain an early indication as to how an election has turned out, as in many elections the actual result may take hours to count. History There are different views on who invented the exit poll. Marcel van Dam, Dutch sociologist and former politician, says he was the inventor, by being the first to implement one during the Dutch legislative elections on February 15, 1967. Other sources say Warren Mitofsky, an American pollster, was the first. For CBS News, he devised an exit poll in the Kentucky gubernatorial election in November that same year. Not withstanding this, the mention of the first exit polls date back to the 1940s when such a poll was held in Denver, Colorado. Purpose Exit ...

Straw Poll
A straw poll, straw vote, or straw ballot is an ad hoc or unofficial vote. It is used to show the popular opinion on a certain matter, and can be used to help politicians know the majority opinion and help them decide what to say in order to gain votes. Straw polls provide dialogue among movements within large groups. Impromptu straw polls often are taken to see if there is enough support for an idea to devote more meeting time to it, and (when not a secret ballot) for the attendees to see who is on which side of a question. However, in meetings subject to Robert's Rules of Order, motions to take straw polls are not allowed. Among political bodies, straw polls often are scheduled for events at which many people interested in the polling question can be expected to vote. Sometimes polls conducted without ordinary voting controls in place (i.e., on an honor system, such as in online polls) are also called "straw polls". The idiom may allude to a straw (thin plant stalk) held up ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polling (computer Science)
Polling, or polled operation, in computer science, refers to actively sampling the status of an external device by a client program as a synchronous activity. Polling is most often used in terms of input/output (), and is also referred to as polled or software-driven . A good example of hardware implementation is a watchdog timer. Description Polling is the process where the computer or controlling device waits for an external device to check for its readiness or state, often with low-level hardware. For example, when a printer is connected via a parallel port, the computer waits until the printer has received the next character. These processes can be as minute as only reading one bit. This is sometimes used synonymously with ' busy-wait' polling. In this situation, when an operation is required, the computer does nothing other than check the status of the device until it is ready, at which point the device is accessed. In other words, the computer waits until the device ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polled Livestock
Polled livestock are livestock without horns in species which are normally horned. The term refers to both breeds and strains that are naturally polled through selective breeding and also to naturally horned animals that have been disbudded. Natural polling occurs in cattle, yaks, water buffalo, and goats, and in these animals it affects both sexes equally; in sheep, by contrast, both sexes may be horned, both polled, or only the females polled. The history of breeding polled livestock starts about 6000 years BC. Terminology The archaic term or is sometimes used to refer to hornless livestock (especially cattle) in folk songs, folk tales, and poetry, and in the name of the polled Irish Moiled cattle breed. "Muley" derives from Irish and Scottish Gaelic ''maol'', and Welsh ''moel''. Genetics In cattle, the polled allele is genetically dominant to that for horns. The polled trait is far more common in beef breeds than in dairy breeds. CRISPR technology is being developed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Election Verification Exit Poll
An election verification exit poll (EVEP) is a relatively new concept in polling, intended to improve the accuracy of exit polls to such an extent that they can be used to verify election results. Traditional (media) exit polling relies on small samples, wheres EVEPs propose to use larger samples. Motivation A USAID document (written for US workers observing foreign elections) concludes that parallel vote tabulation "is the preferred tool for verifying election results where the context and local capacity permit. Exit polls can collect important data for understanding voter intent, providing insight into political and social dynamics ..However, they provide limited hard evidence of manipulation." In the United States, exit polling is not accurate enough to be used as tool for verification of actual election results. Discrepancies are usually attributed to sampling bias in the exit polls. Exit polling can however be used to question official results. For example, in the 2000 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Poll (livestock)
The poll is a name of the part of an animal's head, alternatively referencing a point immediately behind or right between the ears. This area of the anatomy is of particular significance for the horse. Specifically, the "poll" refers to the occipital protrusion at the back of the skull. However, in common usage, many horsemen refer to the poll joint, between the atlas (C1) and skull as the poll. The area at the joint has a slight depression, and is a sensitive location. Thus, because the crownpiece of a bridle passes over the poll joint, a rider can indirectly exert pressure on the horse's poll by means of the reins, bit, and bridle. Importance of the poll in riding The poll is especially important in riding, as ''correct'' flexion at the poll joint is a sign that the horse is properly on the bit. Over-flexion, with the poll lowered and the neck bent at a cervical vertebra farther down the neck, is usually a sign that the horse is either evading contact or that the rider is tr ...

Max Poll
Max Fernand Leon Poll (21 July 1908 in Ruisbroek – 13 March 1991 in Uccle) was a Belgian ichthyologist who specialised in the Cichlidae. In the years 1946 and 1947 he organised an expedition to Lake Tanganyika. He has described several species of Pseudocrenilabrinae, such as ''Lamprologus signatus'', ''Steatocranus casuarius'', ''Neolamprologus brichardi'', and '' Neolamprologus pulcher''. He was a member of The Royal Academies for Science and the Arts of Belgium, professor at Université Libre de Bruxelles, and conservator at Musée Royal du Congo Belge in Tervuren. He was an honorary member of the American Society of Ichthyologists and Herpetologists.

Polling System
In queueing theory, a discipline within the mathematical theory of probability, a polling system or polling model is a system where a single server visits a set of queues in some order. The model has applications in computer networks and telecommunications, manufacturing and road traffic management. The term polling system was coined at least as early as 1968 and the earliest study of such a system in 1957 where a single repairman servicing machines in the British cotton industry was modelled. Typically it is assumed that the server visits the different queues in a cyclic manner. Exact results exist for waiting times, marginal queue lengths and joint queue lengths at polling epochs in certain models. Mean value analysis techniques can be applied to compute average quantities. In a fluid limit, where a very large number of small jobs arrive the individual nodes can be viewed to behave similarly to fluid queues (with a two state process).
