Previous research has suggested that different addictive behaviours are linked, such that decreases in one may lead to compensatory increases in another, or even that one addiction may lead to another. Such views on "cross addiction" are encouraged b

There is both a theoretical and clinical need to develop a questionnaire that assesses a range of addictive behaviours. The Shorter PROMIS Questionnaire (SPQ) is a 16-scale self-report instrument assessing the use of nicotine, recreational drugs, pre

The principles of narrative therapy imply that autobiographical diaries written by patients in treatment will not only facilitate but also elucidate progress. The relationship between the linguistic content of diaries and progress in treatment was ex

It is plausible to assume that epitaxy is a special case of heterogeneous nucleation in which a restrictive crystallographic relationship exists between substrate and deposit orientations. This would mean that epitaxial substrates should always induc

We report a factor analytic study of the Promis questionnaires, designed to evaluate addiction in 16 behavioural areas. Data were taken from the clinical records of 191 men and 281 women admitted to the Promis Recovery Centre for treatment of addicti

The paper examines convection phenomena during the growth of sodium chlorate crystals from solution. Schlieren observations of sodium chlorate crystals suspended in supersaturated solutions showed that with increase in supersaturation or crystal size

Ingots of In x Ga 1 − x Sb 9 mm diameter x 60 mm long showed 50% fewer straight boundaries and 30% fewer curved boundaries when solidified vertically with a 4 kilogauss horizontal magnetic field. The magnetic field almost entirely stopped formation

For silicon, changes in zone size and shape altered only slightly the appearance of the streamlines for a fixed value of the dimensionless thermocapillary flow parameter. However significant changes were noted in the heat and mass transfer and in the

Melts containing 10%, 30% and 50% InSb were directionally solidified horizontally, vertically and in Skylab 3 and 4. The resulting concentration profiles were much more uniform in the ingots solidified horizontally. Fluctuations in composition occurr

InSb-GaSb solid solution ingots prepared by directional solidification aboard Skylab and on earth consist primarily of twins with (111) twin planes parallel to the direction of solidification and growth directions that lie along 〈211〉, 〈110〉,
