Alcune proprieta′ di monotonia generalizzata

Questo lavoro pone la monotonia generalizzata come un opportuno strumento per uno sviluppo controllato di funzioni scalari e vettoriali. E' cosi possibile caratterizzare la relazione tra su spazi vettoriali.

Summary Some generalized monotonicity properties are analyzed both for scalar and vector functions. In particular the relation between and the class of functions, which are able to preserve it, are studied.

Mokken scale analysis for polychotomous items: theory,a computer program and an empirical application

This paper contains three subjects. First, an extension of Mokken's nonparametric item response models from dichotomous items to items with two or more ordered answer categories is proposed. Second, a computer program to analyze multicategory item scores is presented. This program is called MSP. The analyses by means of MSP are based on the multicategory extension of Mokken's theory. Finally, an application of MSP to empirical multicategory test data is presented in order to illuminate its possibilities.

The evidence indicates that remedies of compensation and re-employment afford minimal property rights to unfairly dismissed workers.
