Arthur Roy Clapham
Arthur Roy Clapham (24 May 1904 – 18 December 1990), was a British botanist. Born in Norwich and educated at Downing College, Cambridge, Clapham worked at Rothamsted Experimental Station as a crop physiologist (1928–30), and then took a teaching post in the botany department at Oxford University. He was Professor of Botany at Sheffield University 1944–69 and vice chancellor of the university during the 1960s. He coauthored the ''Flora of the British Isles'', which was the first, and for several decades the only, comprehensive flora of the British Isles published in 1952 and followed by new editions in 1962 and 1987. In response to a request from Arthur Tansley, he coined the term ecosystem in the early 1930s. Early life and education Clapham was born in Norwich to George Clapham, an elementary school teacher and Dora Margaret Clapham, ''née'' Harvey. He was the oldest of three children and the only boy. He attended the City of Norwich School, where he sat the Cambridge S ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Norwich
Norwich () is a cathedral city and district of Norfolk, England, of which it is the county town. Norwich is by the River Wensum, about north-east of London, north of Ipswich and east of Peterborough. As the seat of the See of Norwich, with one of the country's largest medieval cathedrals, it is the largest settlement and has the largest urban area in East Anglia. The population of the Norwich City Council local authority area was estimated to be 144,000 in 2021, which was an increase from 143,135 in 2019. The wider built-up area had a population of 213,166 in 2019. Heritage and status Norwich claims to be the most complete medieval city in the United Kingdom. It includes cobbled streets such as Elm Hill, Timber Hill and Tombland; ancient buildings such as St Andrew's Hall; half-timbered houses such as Dragon Hall, The Guildhall and Strangers' Hall; the Art Nouveau of the 1899 Royal Arcade; many medieval lanes; and the winding River Wensum that flows through the city ...

First Class Honours
The British undergraduate degree classification system is a grading structure for undergraduate degrees or bachelor's degrees and integrated master's degrees in the United Kingdom. The system has been applied (sometimes with significant variations) in other countries and regions. History The classification system as currently used in the United Kingdom was developed in 1918. Honours were then a means to recognise individuals who demonstrated depth of knowledge or originality, as opposed to relative achievement in examination conditions. Concern exists about possible grade inflation. It is claimed that academics are under increasing pressure from administrators to award students good marks and grades with little regard for those students' actual abilities, in order to maintain their league table rankings. The percentage of graduates who receive a First (First Class Honours) has grown from 7% in 1997 to 26% in 2017, with the rate of growth sharply accelerating toward the end of ...

British Ecological Society
The British Ecological Society is a learned society in the field of ecology that was founded in 1913. It is the oldest ecological society in the world. The Society's original objective was "to promote and foster the study of Ecology in its widest sense" and this remains the central theme guiding its activities today. The Society had, circa 2013 around 4,000 members of which 14% are students. Of its members, 42% are outside the United Kingdom, in a total of 92 countries. The head office is located in London. History The Society evolved out of the British Vegetation Committee, which was founded in 1904 to promote the survey and study of vegetation in the British Isles. This initiative was in turn the outcome of what many historians perceive to have been the emergence of modern ecology in the 1890s. The British Ecological Society's inaugural meeting was held at University College London on 12 April 1913 and was attended by 47 members. Sir Arthur Tansley became the first Presid ...

Sampling Methods
In statistics, quality assurance, and survey methodology, sampling is the selection of a subset (a statistical sample) of individuals from within a statistical population to estimate characteristics of the whole population. Statisticians attempt to collect samples that are representative of the population in question. Sampling has lower costs and faster data collection than measuring the entire population and can provide insights in cases where it is infeasible to measure an entire population. Each observation measures one or more properties (such as weight, location, colour or mass) of independent objects or individuals. In survey sampling, weights can be applied to the data to adjust for the sample design, particularly in stratified sampling. Results from probability theory and statistical theory are employed to guide the practice. In business and medical research, sampling is widely used for gathering information about a population. Acceptance sampling is used to determine if ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Journal Of Ecology
The ''Journal of Ecology'' is a bimonthly peer-reviewed scientific journal covering all aspects of the ecology of plants. It was established in 1913 and is published by Wiley-Blackwell on behalf of the British Ecological Society. The journal publishes papers on plant ecology (including algae) in both terrestrial and aquatic ecosystems. In addition to population and community ecology, articles on biogeochemistry, ecosystems, microbial ecology, physiological plant ecology, climate change, molecular genetics, mycorrhizal ecology, and the interactions between plants and organisms such as animals or bacteria, are published regularly. Besides primary research articles, it publishes "Essay Reviews" and "Forum" articles. In 2008, the first papers in a new series called "Future Directions" were published. These short papers are intended to stimulate debate as to where a field within plant ecology is going, or needs to go. In addition, the journal contains a long-running series on the "Bio ...

Donald Pigott
Christopher Donald Pigott (7 April 1928 – 11 September 2022) was a British botanist who was the fourth Director, Cambridge University Botanic Garden (1984–1995), succeeding Max Walters. Life and career Pigott was born on 7 April 1928. He was educated at Cambridge from 1946, where he was taught by two previous Directors, Humphrey Gilbert-Carter (1921–1950) and Max Walters (1973–1983). Forming a friendship with the latter he was persuaded to spend the summer of 1949 in Uppsala and Helsinki universities where he was impressed by the mapping of the Scandinavian flora and returned to work with Walters on similar projects for the British Isles and used this method in his PhD thesis on Thyme. Under Professor Harry Godwin he also worked on the design of the Botanic Garden's ecological mound. After leaving Cambridge he moved to Sheffield University as Lecturer in Botany. He returned to Cambridge in 1984 to become Director of the Garden. On leaving Cambridge in 1995 he was succ ...

Mathematical Statistics
Mathematical statistics is the application of probability theory, a branch of mathematics, to statistics, as opposed to techniques for collecting statistical data. Specific mathematical techniques which are used for this include mathematical analysis, linear algebra, stochastic analysis, differential equations, and measure theory. Introduction Statistical data collection is concerned with the planning of studies, especially with the design of randomized experiments and with the planning of surveys using random sampling. The initial analysis of the data often follows the study protocol specified prior to the study being conducted. The data from a study can also be analyzed to consider secondary hypotheses inspired by the initial results, or to suggest new studies. A secondary analysis of the data from a planned study uses tools from data analysis, and the process of doing this is mathematical statistics. Data analysis is divided into: * descriptive statistics - the part of st ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Karl Pearson
Karl Pearson (; born Carl Pearson; 27 March 1857 – 27 April 1936) was an English mathematician and biostatistician. He has been credited with establishing the discipline of mathematical statistics. He founded the world's first university statistics department at University College, London in 1911, and contributed significantly to the field of biometrics and meteorology. Pearson was also a proponent of social Darwinism, eugenics and scientific racism. Pearson was a protégé and biographer of Sir Francis Galton. He edited and completed both William Kingdon Clifford's ''Common Sense of the Exact Sciences'' (1885) and Isaac Todhunter's ''History of the Theory of Elasticity'', Vol. 1 (1886–1893) and Vol. 2 (1893), following their deaths. Biography Pearson was born in Islington, London into a Quaker family. His father was William Pearson QC of the Inner Temple, and his mother Fanny (née Smith), and he had two siblings, Arthur and Amy. Pearson attended University College Scho ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Statistical Analysis
Statistical inference is the process of using data analysis to infer properties of an underlying distribution of probability.Upton, G., Cook, I. (2008) ''Oxford Dictionary of Statistics'', OUP. . Inferential statistical analysis infers properties of a population, for example by testing hypotheses and deriving estimates. It is assumed that the observed data set is sampled from a larger population. Inferential statistics can be contrasted with descriptive statistics. Descriptive statistics is solely concerned with properties of the observed data, and it does not rest on the assumption that the data come from a larger population. In machine learning, the term ''inference'' is sometimes used instead to mean "make a prediction, by evaluating an already trained model"; in this context inferring properties of the model is referred to as ''training'' or ''learning'' (rather than ''inference''), and using a model for prediction is referred to as ''inference'' (instead of ''prediction''); ...
