This paper describes the implementation of a factorial survey within the SOEP-Pretest of 2008 and investigates (1) respondents’ comments about the vignettes, (2) interviewers’ assessments of respondents comprehension and willingness to answer, and (3) response behavior regarding response time, use of the answering scale, and consistency of evaluations by different age groups and educational bac...

Self-reported work disability is analyzed in the US and The Netherlands. The raw data show that Dutch respondents much more often report that they have a work limiting health problem than respondents in the US. The difference remains when controlling for demographic characteristics and observed onsets of health problems. Respondent evaluations of work limitations of hypothetical persons describ...

Arithmetic expression dags are widely applied in robust geometric computing. In this paper we restructure expression dags by balancing consecutive additions or multiplications. We predict an asymptotic improvement in running time and experimentally confirm the theoretical results. Finally, we discuss some pitfalls of the approach resulting from changes in evaluation order.

With the exponential growth of forensic psychology over recent decades, increasing numbers of clinical psychologists with little specialized training are becoming principal providers of forensic assessments. On the basis of results from an empirical study, the authors analyze 3 fundamental problems with these psychologists' reports on competence to stand trial and provide recommendations for im...

In this research, we aim at the establishment of a method of controlling dialogues in accordance with the changes of performance in computation. So that the system takes the most suitable dialogue strategy according to performance in computation, it needs to calculate evaluation functions modeled with performance in computation in the inside all time. In this paper, we clarify dialogue efficien...
