THIS study is a follow-up of earlier reports on general practice by Collings (1950), Hadfield (1953) and Taylor (1954) and focusses on the doctor's tools just as the recent investigation by Eimerl and Pearson (1966) followed up the earlier classic of Bradford Hill to see what changes there had been since his report on the doctors' work-week was published in 1951. A large number of other studies...

Tree snails of the family Partulidae have declined on Guam since World War II. One species, indigenous to the western Pacific, Partu/a radio/ata, is still locally common along stream courses in southern areas of the island. The Mariana Island endemic Samoanajragilis is present but not found in abundance anywhere on Guam. Partu/a gibba, another Mariana endemic, is currently known only from one i...

This is the last book by the late Dr. Hadfield and its publication came almost at the time of his death, which ended a very long and productive life. He was an inspiring doctor and teacher; as an author, he was prolific and informative, but rarely exciting. Introduction to psychotherapy is very much in line with the earlier books. It gives a rapid historical review of psychological treatment me...

Adolescence may be defined as the period of life 'rom the end of childhood, and indicated physically by the bodily changes associated with puberty, continuing until full physical development is achieved, and adult status in society is recognised. Unfortunately there is incomplete agreement as to the time-period involved. Some authors (Sandstrom) consider the years from 12-16, the age 10-12 bein...

The off-switch game is a game theoretic model of a highly intelligent robot interacting with a human. In the original paper by Hadfield-Menell et al. (2016b), the analysis is not fully game-theoretic as the human is modelled as an irrational player, and the robot’s best action is only calculated under unrealistic normality and soft-max assumptions. In this paper, we make the analysis fully game...
