SummaryThis study investigates the reasons people give for taking overdoses of drugs. A representative sample of 128 subjects were interviewed immediately after their recovery from an overdose. During the interview they were given alternative reasons for taking overdoses and asked to choose any that applied to them. Spontaneous comments about suicidal intent were also recorded. Of the subjects, 44 per cent indicated that they had wanted to die. On the basis of their choices 33 per cent were ‘seeking help’, 42 per cent ‘escaping from the situation’, 52 per cent ‘obtaining relief from a terrible state of mind’ and 19 per cent ‘trying to influence someone’. The association between these various reasons and other expected effects or feelings associated with the act were examined by means of multidimensional scaling analysis. In addition, the characteristics of those expressing suicidal intent and other reasons were studied, together with such consequences as toxic effects and psychiatric after-care. The possibility is discussed that a large proportion of those indicating suicidal intent do so either to gain social acceptability for their act or to influence helping agencies.

This study aims to determine the sustainability status of the Re-Opening Oil Wells of Bojonegoro Regency, East Java, Indonesia. The method used in this research is Multidimensional Scaling analysis which is implemented using Rap-Re-Opening Oil Wells software. Existing status of Wells Bojonegoro Re-Opening Oil Sustainability Less Sustainable with the weighting value of each dimension is 34.56%, 39.73%, 45.25%, 37.90%, 57.00%. The strategy to increase the addition of status values from the 5 dimensions of the Sustainability Index, evaluated only one dimension that is sustainable with a fairly good status. The results obtained from the improvement scenario obtained by the respective percentage figures as follows; Ecology 41.44%, Economics 61.62%, Social and Culture 45.25%, Technology 42.02%, Institutional 61, 29%. Thus the strategy to increase sustainable status can be improved by the Oil Wells Rap-Re-Opening Method.

Using an individual differences multidimensional scaling model of perception, this crosslanguage investigation seeks to determine what dimensions underlie the perception of linguistic tone, and to what extent an individual's language background (Thai, Yoruba or American English) influences his perception. Dissimilarities data were obtained from subjects' paired-comparison judgments of 13 different pitch patterns superimposed on a synthetic speech-like syllable. A multidimensional scaling analysis of the data for the total group revealed that five dimensions - interpretively labeled, AVERAGE PITCH, DIRECTION, LENGTH, EXTREME ENDPOINT and SLOPE - best summarize the perceptual structure underlying the dissimilarities data. Language subgroup variation in relative importance of these dimensions appears to be primarily related to subgroup differences in the way pitch is used to convey linguistic information. Discriminant analysis showed that most individual speakers of a tone language (Thai or Yoruba) can be easily distinguished from speakers of a nontone language (English) on the basis of their distinctive patterns of perceptual saliency for these five dimensions. Regression analysis indicated that the DIRECTION and SLOPE dimensions closely correspond to certain earlier proposed binary distinctive features of tone.
