This paper follows Locke's treatment of four problems of measurement from the early Drafts A and B of the Essay...
A cohort study tracks two or more groups forward from exposure to outcome. This type of study can be done by going ahead in time from the present (prospective cohort study) or, alternatively, by going back in time to comprise the cohorts and following them up to the present (retrospective cohort study). A cohort study is the best way to identify incidence and natural history of a disease, and c...
Recent medical research has been based on a flawed rationale of clinical innovation (here termed the 'basic-to-mega model') which neglects the human organism as a vital focus of clinical scientific study. The consequent over-concentration upon cellular and population levels of analysis has probably damaged the rate of therapeutic progress. The key role in medical research should be acknowledged...
Interpreting the natural environment in the cultural context of a museum is common practice in the early 21st century. It was also quite common in the 19th century. This chapter considers some of the key discourses in natural history and science museums to reveal a rich legacy of engagement with the environment.

THE natural history of migraine raises many problems for clinicians. The main features of the syndrome are well known and have been described in medical and lay literature from early times.
