The Green Lady Hostel, Littlehampton (reserved for several months by the C.A.M.W.) was occupied for a fortnight at the end of April by a group of 48 women of very varying ages, in the charge of three members of the C.A.M.W., in addition to the usual household staff of the Hostel. About half the holiday-makers were girls and women placed out under the Guardianship Scheme of the C.A.M.W., while t...

on those legally certified as feebleminded, and studies in both this and other institutions (5) show consistently that the I.Q.'s of such persons range between about 50 and about 110, with an average between 70 and 80 on such tests as the Wechsler, Stanford-Binet, Progressive Matrices, Porteous Mazes and Kohs Blocks. This I.Q. range extends much higher than might be expected by those who adopt ...

A recent survey of the occupations and home conditions of mentally defective persons in an industrial area of roughly half a million popu...

Suppose that we are given a set of n elements d of which are “defective”. A group test can check for any subset, called a pool, whether it contains a defective. It is well known that d defectives can be found by using O(d logn) pools. This nearly optimal number of pools can be achieved in 2 stages, where tests within a stage are done in parallel. But then d must be known in advance. Here we exp...

Group testing is the problem of finding d defectives in a set of n elements, by asking carefully chosen subsets (pools) whether they contain defectives. Strategies are preferred that use both a small number of tests close to the information-theoretic lower bound d log2 n, and a small constant number of stages, where tests in every stage are done in parallel, in order to save time. They should e...

followed by a Conference on the Mentally Defective and the Poor Law, which was well attended by representatives of Boards of Guardians. The speeches made dealt chiefly with the work that Boaids of Guardians are doing in providing training and occupation for defectives under their care, and with the difficulties that are created by the failure of so many Local Authorities to carry out their duti...

were the gathering together of reliable statistics of the number of mental defectives in Somerset and the collection of a fund to begin a farm colony for the feeble-minded. At the end of the first two years 1,933 patients had been visited; four of whom were subsequently placed under guardianship and 43 referred to the Local Authority under the Mental Deficiency Act 1913. In the meantime 25 pati...
