In the UK, the term lecturer is ambiguous and covers several academic ranks. The key distinction is between permanent/open-ended or temporary/fixed-term lectureships.
A permanent lecturer in UK universities usually holds an open-ended position that covers teaching, research, and administrative responsibilities. Permanent lectureships are tenure-track or tenured positions that are equivalent to an assistant or associate professorship in North America. After a number of years, a lecturer may be promoted based on his or her research record to become a senior lecturer. This position is below reader and professor.
Research lecturers (where they are permanent appointments) are the equivalent in rank of lecturers and senior lecturers, but reflect a research-intensive orientation. Research lecturers are common in fields such as medicine, engineering, and biological and physical sciences.
In contrast, fixed-term or temporary lecturers are appointed for specific short-term teaching needs. These positions are often non-renewable and are common post-doctoral appointments. In North American terms, a fixed-term lecturer can hold an equivalent rank to assistant professor without tenure. Typically, longer contracts denote greater seniority or higher rank. Teaching fellows may also sometimes be referred to as lecturers—for example, Exeter named some of that group as education and scholarship lecturers (E & S) to recognise the contribution of teaching, and elevate the titles of teaching fellows to lecturers. Some universities also refer to graduate students or others, who undertake ad-hoc teaching for a department sessional lecturers. Like adjunct professors and sessional lecturers in North America, these non-permanent teaching staff are often very poorly paid (as little as £6000 p.a. in 2011-12). These varying uses of the term lecturer cause confusion for non-UK academics.
As a proportion of UK academic staff, the proportion of permanent lectureships has fallen considerably. This is one reason why permanent lectureships are usually secured only after several years of post-doctoral experience. Data from the Higher Education Statistics Agency show that in 2013–14, 36 per cent of full- and part-time academic staff were on fixed-term contracts, down from 45 per cent a decade earlier. Over the same period, the proportion of academic staff on permanent contracts rose from 55 per cent to 64 per cent. Others were on contracts classed as "atypical".'
Thetford is a market town and civil parish in the Breckland district of Norfolk, England. It is on the A11 road between Norwich and London, just east of Thetford Forest. The civil parish, covering an area of 29.55 km2 (11.41 sq mi), has a population of 24,340.
There has been a settlement at Thetford since the Iron Age, and parts of the town predate the Norman Conquest; Thetford Castle was established shortly thereafter. Roger Bigod founded the Cluniac Priory of St Mary in 1104, which became the largest and most important religious institution in Thetford. The town was badly hit by the dissolution of the monasteries, including the castle's destruction, but was rebuilt in 1574 when Elizabeth I established a town charter. After World War II, Thetford became an "overspill town", taking people from London, as a result of which its population increased substantially. Thetford was the headquarters of Tulip International, large-scale manufacturers of bacon, beef and pork until its closure in 2010.
Thetford railway station is served by the Breckland line and is one of the best surviving pieces of 19th century railway architecture in East Anglia.
