background & aim : researchers in the nursing science study complex constructs for which valid and reliable instruments are needed. when an instrument is created, psychometric testing is required, and the first-step is to study the content validity of the instrument. this article focuses on the process used to assess the content validity. methods & materials : this article examines the definiti...

OBJECTIVES The goal of this project was to develop the first disease-specific instrument for the evaluation of quality of life in chronic pancreatitis. METHODS Focus groups and interview sessions were conducted, with chronic pancreatitis patients, to identify items felt to impact quality of life which were subsequently formatted into a paper-and-pencil instrument. This instrument was used to ...

Hedging strategies in bond markets are computed by martingale representation and the choice of a suitable of numeraire, based on the Clark-Ocone formula in a model driven by the dynamics of bond prices. Applications are given to the hedging of swaptions and other interest rate derivatives and we compare our approach to delta hedging when the underlying swap rate is modeled by a diffusion process.

This paper introduces the general notion of elastic interfaces and the derived concepts of transparency and tailorability, and exemplifies the notions in the domain of maritime instrumentation. It concludes that maritime automation to some degree already follows principles of transparency and possibly might benefit from adopting a disciplined version of tailorability.
