The CADS Research Cluster People, Power and Diversity aims to further theoretical and methodological debates on the classifications of human difference, such as gender, race, ethnicity, sexuality, class, age, ability, religion, level of development, time, etc., and the way these classifications organize…

Some offenders are given short prison sentences. They tend to be people who are generally not faring well before they go to prison; they may have difficulty finding a job for instance. A short spell in prison can make them even more vulnerable. Attention therefore needs to be paid to continual supervision…

Since the 16th century, religious concerns have motivated the study of Old English and its speakers. In the 19th century, scholars turned to the study of Old English literature in particular to find traces of pre-Christian, ‘Germanic’ religion, as discussed in Eric G. Stanley’s seminal work The Search…
