Especially in research-intensive universities, lecturers lead research groups and supervise research students, as well as teach. After a number of years, lecturers might be promoted to senior lecturers with increasing research, leadership, and administrative responsibilities. In most research-intensive universities (such as those that are part of theRussell Groupand1994 Group), a senior lecturer position is between alecturerand areader, with a strong focus on research. At the same time, in some universities (for instance, University of Leeds), the rank of reader is no longer used for new appointments. A senior lecturer position can be a parallel position to reader in other universities. In some universities (notably post-1992 UK universities and former polytechnics), the senior lecturer and reader ranks denote different responsibilities, with the former being more teaching-focused and the latter being more research-focused. Senior lecturers can progress to either a reader or aprofessorposition.
Chesterfield is a large market town and borough in Derbyshire, England, 24 miles (39 km) north of Derby and 11 miles (18 km) south of Sheffield at the confluence of the River Rother and River Hipper. Including Whittington, Brimington and Staveley, it had a population of 103,801 in 2012, making it Derbyshire's second largest town. It has been traced to a soon-abandoned Roman fort of the 1st century AD. The name of the later Anglo-Saxon village comes from the Old English ceaster (Roman fort) and feld (pasture). Its sizeable street market is held three days a week. The town sits on a coalfield, but little visual evidence of mining remains. Its great landmark is the Church of St Mary and All Saints with a crooked spire.
