Pre-Testing Questionnaires Improves Results

Some results on pre-monotone operators

‎In this paper‎, ‎some properties of pre-monotone operators are proved‎. ‎It is shown that in a reflexive Banach space‎, ‎a full domain multivalued $sigma$-monotone operator with sequentially norm$times$weak$^*$ closed graph is norm$times$weak$^*$ upper semicontinuous‎. ‎The notion of $sigma$-convexity is introduced and the‎ ‎relations between the $sigma$-monotonicity and $sigma$-convexity is i...

Quiescence Management Improves Interoperability Testing

At any level of computer networks, interoperability testing generally deals with several components that communicate while trying to provide a designated service. When a component remains silent, the assigned testing verdict is generally Fail, assuming that its behavior is non-conformant. Sometimes, this silence may be anticipated given the component’s specifications. In these cases, the fail v...

Internet and written respiratory questionnaires yield equivalent results for adolescents

This study compared results from Internet and written questionnaires about respiratory symptoms in order to find out if both forms of the survey yielded the same answers. One thousand seventy-one students, ages 13 to 17, were asked to complete either an Internet or a written questionnaire. The demographic characteristics of the participants equalled those of the general Dutch adolescent populat...

Power gain by pre - testing ?

The aim of this paper is to study whether it is possible to gain power by pretesting, and to give insight in when this occurs, to what extent and at which price. A pre-test procedure consists of a preliminary test which tests a particular property of a given restricted model, followed by a main test for the main hypothesis regarding the parameter of interest. After acceptance by the preliminary...
