In general, objective functions are applied in data analysis in order to compute optimal reductions of an observed set of data. In the social sciences data often have a non-euclidean (non-metric) structure. Therefore, independently of any particular field of data analysis as, for instance, cluster analysis, factor analysis, linear regression, multidimensional scaling objective functions will be...

Background The Intentional Relationship Model (IRM) proposes six therapeutic modes as ways of relating to clients. The Norwegian self-efficacy for therapeutic mode use (N-SETMU) was found to have a one-component structure. However, its items reflect abstract concepts rather than concrete behaviors. Aim To validate further the N-SETMU by linking its items to the Norwegian client assessment of ...

OBJECTIVE To evaluate the reliability and validity of the London Measure of Unplanned Pregnancy (a U.K.-developed measure of pregnancy intention), in English and Spanish translation, in a U.S. population of women. METHODS A psychometric evaluation study of the London Measure of Unplanned Pregnancy (LMUP), a six-item, self-completion paper measure was conducted with 346 women aged 15-45 who pr...

A system capable of analyzing image sequences of human motion is described. The system is structured as a ·feedback loop between high and low levels: predictions are made at the semantic level, and verifications are sought at the image level. The domain of human motion lends itself to a model-driven analysis, and the system includes a detailed model of the human body. All information extracted ...

In many applications of temporal reasoning we are in­ terested in reasoning incrementally In particular, given a CSP of temporal constrains and a new constraint, we want to maintain certain properties in the extended CSP (e.g., a solution), rather than recomputing them from scratch. The Point Algebra (PA) and the Interval Algebra (IA) are two well-known frameworks for qualitative tem­ poral rea...
