In a recent project the Ada language turned out to be not as flexible as we expected it to be. This forced us to model our application in a way that was less elegant, less maintainable and less efficient. In this paper we propose to add a language construct to the language that would enable us to do what we were missing. The extension is based on finite unions with dispatching and can quite eas...

A hyperbolic bration is set of q ?1 hyperbolic quadrics and two lines which together partition the points of PG(3; q). The classical example of a hyperbolic bration comes from a pencil of quadrics; however, several other families are known. In this paper we construct a new family of hyperbolic brations for odd prime powers q. As an application of hyperbolic brations, we note that they can be us...

This article reports an initial validation of an instrument that measures basic interviewing skills and compares its psychometric results with another instrument that has been used more frequently to measure similar skills. Four field supervisors rated 30 students’ videotaped interviews (N=120) using two instruments, the validation, and a comparison instrument. The current validation instrument...

Measures of psychological constructs are validated by testing whether they relate to measures of other constructs as specified by theory. Each test of relations between measures reflects on the validity of both the measures and the theory driving the test. Construct validation concerns the simultaneous process of measure and theory validation. In this article, we review the recent history of va...

This paper studies the information content of some Ifo indicators. In particular, we investigate whether two Ifo indicators, one on the current business situation, the other on current production development, provide information on revisions of German industrial production. A new feature of our analysis is the construction and use of a real-time dataset. We conclude that the Ifo indicators play...

The Scale of Body Connection (SBC) was created to address the need for a self-report measure to examine body awareness and bodily dissociation in mind-body research. Developed in the U.S.A., it has been translated into many languages and tested for validity of scale translation. The burgeoning of mind-body research and the widespread use of the SBC scale underscored the need for critical assess...

We introduce the concept of knowledge management orientation (KMO) – the degree to which a firm demonstrates behaviors of organized and systematic knowledge management (KM) implementation. Based on an extensive review of the KM literature, the KMO concept is operationalized as a second-order latent construct consisting of four main component factors: organizational memory, knowledge sharing, kn...

Software developer competence is essential for developing quality systems. Typically past experience, education and training, academic and professional references, tests, and interviews are used to assess developer competence. In this paper we propose that to obtain a holistic assessment of competence, it is essential to evaluate developer perceptions and beliefs on what they can achieve since ...
