American literatureAmerican literature is literature written or produced in the United States of America and in the colonies that preceded it. The American literary tradition thus is part of the broader tradition of English-language literature, but also includes literature of other traditions produced in the United States and in other immigrant languages. Furthermore, a rich tradition of oral storytelling exists amongst Native Americans. The American Revolutionary Period (1775–1783) is notable for the political writings of Benjamin Franklin, Alexander Hamilton, Thomas Paine, and Thomas Jefferson.
VariogramIn spatial statistics the theoretical variogram, denoted , is a function describing the degree of spatial dependence of a spatial random field or stochastic process . The semivariogram is half the variogram. In the case of a concrete example from the field of gold mining, a variogram will give a measure of how much two samples taken from the mining area will vary in gold percentage depending on the distance between those samples. Samples taken far apart will vary more than samples taken close to each other.
English literatureEnglish literature is literature written in the English language from the United Kingdom, its Crown Dependencies and Overseas Territories, the Republic of Ireland, the United States, and the countries of the former British Empire. The English language has developed over the course of more than 1,400 years. The earliest forms of English, a set of Anglo-Frisian dialects brought to Great Britain by Anglo-Saxon invaders in the fifth century, are called Old English.
British literatureBritish literature is literature from the United Kingdom of Great Britain and Northern Ireland, the Isle of Man, and the Channel Islands. This article covers British literature in the English language. Anglo-Saxon (Old English) literature is included, and there is some discussion of Latin and Anglo-Norman literature, where literature in these languages relate to the early development of the English language and literature. There is also some brief discussion of major figures who wrote in Scots, but the main discussion is in the various Scottish literature articles.
Geologic modellingGeologic modelling, geological modelling or geomodelling is the applied science of creating computerized representations of portions of the Earth's crust based on geophysical and geological observations made on and below the Earth surface. A geomodel is the numerical equivalent of a three-dimensional geological map complemented by a description of physical quantities in the domain of interest. Geomodelling is related to the concept of Shared Earth Model; which is a multidisciplinary, interoperable and updatable knowledge base about the subsurface.
Mass dewormingMass deworming, also called preventive chemotherapy, is the process of treating large numbers of people, particularly children, for helminthiasis (for example soil-transmitted helminths (STH)) and schistosomiasis in areas with a high prevalence of these conditions. It involves treating everyone – often all children who attend schools, using existing infrastructure to save money – rather than testing first and then only treating selectively.
African-American literatureAfrican American literature is the body of literature produced in the United States by writers of African descent. It begins with the works of such late 18th-century writers as Phillis Wheatley. Before the high point of enslaved people narratives, African-American literature was dominated by autobiographical spiritual narratives. The genre known as slave narratives in the 19th century were accounts by people who had generally escaped from slavery, about their journeys to freedom and ways they claimed their lives.
United States Environmental Protection AgencyThe Environmental Protection Agency (EPA) is an independent executive agency of the United States federal government tasked with environmental protection matters. President Richard Nixon proposed the establishment of EPA on July 9, 1970; it began operation on December 2, 1970, after Nixon signed an executive order. The order establishing the EPA was ratified by committee hearings in the House and Senate. The agency is led by its administrator, who is appointed by the president and approved by the Senate.
Cohen's kappaCohen's kappa coefficient (κ, lowercase Greek kappa) is a statistic that is used to measure inter-rater reliability (and also intra-rater reliability) for qualitative (categorical) items. It is generally thought to be a more robust measure than simple percent agreement calculation, as κ takes into account the possibility of the agreement occurring by chance. There is controversy surrounding Cohen's kappa due to the difficulty in interpreting indices of agreement.
